Description

Technical Field

[0001] The utility model relates to a motion conversion mechanism of a P button pressure block and belongs to the field of automobile parts. Background Art

[0002] The traditional hand-shift gear is arranged at the bottom of the steering wheel. Since it is more convenient to operate while the vehicle is driving, it has gradually replaced other gear shifting methods and become the mainstream.

[0003] For example, a Chinese utility model with publication number CN211175319U discloses a waterproof structure for an electronic shift handle button for automobiles, including a handle frame and a circuit board, wherein a flexible pad covering the circuit board and a waterproof platform suspending the circuit board are arranged in the handle frame. The utility model utilizes the existing limited space to design a waterproof platform, suspends the P gear button circuit board, and the circuit board is covered with a rubber pad to achieve effective isolation from the liquid flowing down the gap. However, although it has a waterproof effect, the overall structure is still relatively complex and the cost is relatively high. Utility Model Content

[0004] The purpose of the utility model is to overcome the shortcomings and deficiencies of the prior art and to provide a motion conversion mechanism for a P button pressure block.

[0005] A motion conversion mechanism of a P button pressure block, comprising a shell, a mounting cavity being provided in the shell, a P button, a pressure block, a micro switch and a circuit board electrically connected to the micro switch being installed in the mounting cavity, the P button being horizontally arranged in the shell, the P button comprising a pressing portion and a pushing portion connected to the pressing portion and extending into the mounting cavity, the lower end surface of the pushing portion abutting against the pressure block, the micro switch being located below the pressure block and abutting against the pressure block, the P button drives the pushing portion to move vertically through a pressing action to trigger the micro switch to connect to the circuit board, the motion conversion mechanism forms a compact overall structure by concentrating the P button, the pressure block, the micro switch and the circuit board in a shell, thereby reducing space occupancy and improving design flexibility, converting linear motion into vertical motion through the pressure block, simplifying the complex motion conversion process in a traditional shifting mechanism, reducing the possibility of mechanical wear and improving the durability of the system.

[0006] Preferably, the lower end surface of the pushing portion gradually tilts upward from the end close to the pressing portion to the end away from the pressing portion, and the upper end surface of the pressing block and the lower end surface of the pushing portion are matched at an inclination angle to abut against each other. The matching design of the inclination angle between the pressing block and the lower end surface of the pushing portion can achieve more efficient force transmission. When the user presses the P button, the force can be more evenly applied to the pressing block, thereby effectively triggering the micro switch and reducing the force loss. The resistance can be increased or decreased by changing the angle of the inclined surface of the pressing block, thereby meeting the force value requirement, thereby achieving dynamic adjustment of the pressing resistance.

[0007] Furthermore, a limiting groove is provided on the shell, and one end of the pressing block extends into the limiting groove and abuts against its bottom surface. The limiting groove is used to limit the movement stroke of the pressing block to avoid dislocation of the pressing block during the pushing process, which affects the normal use of the mechanism.

[0008] Preferably, the P button includes a mounting groove opening downward, the micro switch is arranged in the mounting groove, and the circuit board is arranged at the bottom of the micro switch. The mounting groove opening downward is designed so that the micro switch can be easily embedded in the mounting groove, which can simplify the installation process and facilitate subsequent maintenance and replacement. The user only needs to easily disassemble it for inspection or replacement without disassembling the entire mechanism. By arranging the circuit board at the bottom of the micro switch, space is saved and the compactness of the entire structure is improved. This longitudinal layout helps to achieve higher integration in a limited installation space, making the device design more flexible and beautiful.

[0009] Furthermore, the outside of the micro switch is coated with waterproof rubber, and the waterproof rubber extends to the outside of the circuit board. By coating the outside of the micro switch with waterproof rubber, moisture and other liquids can be effectively blocked from entering the inside of the switch, thereby improving the reliability and stability of the equipment in a humid environment and reducing the risk of failure due to moisture intrusion. The waterproof rubber coating can provide additional protection to prevent dust, dirt and chemicals from damaging the micro switch and circuit board, thereby extending the service life of the entire device and ensuring its long-term stable operation. The external waterproof rubber forms a protective barrier, which effectively isolates the micro switch and circuit board from direct contact with the external environment, thereby reducing circuit failures caused by corrosion and maintaining the stability of signal transmission.

[0010] Preferably, the push part, the pressure block, the micro switch and the circuit board are arranged in a stacked structure, which can effectively reduce the height of the overall device and save installation space. This compact design enables the device to be efficiently integrated in a limited space and meet the needs of miniaturization.

[0011] Preferably, a return rubber fixed to the inner wall is provided in the mounting cavity, and the P button also includes a reset block, which abuts against the top of the return rubber. The reset block pushes the return rubber to deform through the pressing action of the P button. The design of the return rubber can ensure that after the P button is pressed, the button can be quickly and smoothly reset to its initial state, avoiding the button from being in a pressed state for a long time, thereby improving the response speed and reliability of the device. By designing the interaction between the reset block and the return rubber, clearer pressing feedback can be provided, making it easier for users to judge the state of the button during operation, thereby improving the intuitiveness of use.

[0012] Preferably, a buckle cover is provided on the shell, and the buckle cover is used to protect the shell and parts inside the shell, prevent external interference, etc., and improve the service life and use effect of the motion conversion mechanism.

[0013] The beneficial effects of the utility model are as follows: the motion conversion mechanism forms a compact overall structure by concentrating the P button, the pressure block, the micro switch and the circuit board in a shell, thereby reducing space occupancy and improving design flexibility. The linear motion is converted into vertical motion by the pressure block, which simplifies the complex motion conversion process in the traditional shifting mechanism, reduces the possibility of mechanical wear, and improves the durability of the system.
