[0028] like Figure 1-6 As shown, the car remote key button includes a housing 1, a button 2, and a circuit board 3. The housing 1 is hinged to the button 2 via a cross shaft 4. Specifically, the button 2 is a circular plate, and the housing 1 has a circular mounting groove that mates with the button 2.

[0029] The cross-shaped axis 4 facilitates the pressing of button 2, causing button 2 to rotate along the cross-shaped axis 4. This allows button 2 to cooperate with circuit board 3 to control the vehicle, making the remote key convenient, quick, and more practical.

[0030] Reference Figure 4-6 The cross shaft 4 has a horizontal shaft 7, the button 2 has a mounting hole 11 that mates with the horizontal shaft 7, the cross shaft 4 has a side hole 8, and the housing 1 has a convex shaft 14 that mates with the side hole 8. The horizontal shaft 7 on the cross shaft 4 and the mounting hole 11 on the button 2 work together to achieve a hinge between the cross shaft 4 and the button 2. The side hole 8 on the cross shaft 4 and the convex shaft 14 work together to achieve a hinge between the cross shaft 4 and the housing 1, thereby enabling the button 2 to rotate on the housing 1 when the button 2 is pressed. Specifically, there are two horizontal shafts 7 and two side holes 8. The two horizontal shafts 7 and the two side holes 8 are arranged in a cross shape on the cross shaft 4. The button 2 has two mounting holes 11, and the housing 1 has two convex shafts 14.

[0031] The cross shaft 4 is provided with a weight-reducing groove 9, thereby reducing the weight of the cross shaft 4 and the weight of the entire key.
