Unity2D How to implement jump from platform to platform?

Question

Unity

There are two platforms (top and bottom). I'm trying to do it like this:

The code

var jumpVector = new Vector2(0, jumpSpeed * jumpDirection * Time.deltaTime);

        if (Input.GetKey(KeyCode.Space) && onGround)
        {

            characterRigidbody.AddForce(new Vector2(0, jumpForce * jumpDirection));

            while (!onGround)
            {
                characterRigidbody.velocity = jumpVector;
            }

            jumpDirection *= -1;

            characterRigidbody.gravityScale *= -1;
        }

AddForce было написано, потому что без него объект не может достаточно оттолкнуться от платформы, а скорость прыжка должна быть одной, без замедлений и ускорений.

How to do it right? I am sure that I write only crutches ...

I don’t rummage for the unit, but I’ll give you a tip. If the object is on the platform, then when moving the platform, do += or -= (not =, because then the object will have the same coordinates with the platform, i.e. it will be inside it) of the coordinates of both the platform and the object.
