[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] In one embodiment, see Figure 1-Figure 3 A direct-press push-button electronic parking switch comprises a switch base 9, which is detachably connected to a switch housing 4, on which a button seat 3 is arranged, and the switch housing 4 is provided with rib grooves and buckles, so that the button seat 3 can slide smoothly inside the switch housing 4. The button seat 3 has rib groove guides and buckles that cooperate with the housing, so that the button seat 3 will not have the risk of shaking or falling out in the housing, and can slide smoothly on the housing. A button 1 is arranged on the button seat 3, and working symbols can be added on the surface of the button 1 by spraying paint and laser engraving or spraying paint and pad printing. The button 1 is provided with anti-mistake rib grooves and buckles, which cooperate with the rib grooves and buckles of the button seat 3 to ensure its integrity with the button seat 3 to prevent mis-installation and avoid falling off.

[0018] In one case of this embodiment, a PCB assembly 7 connected to a switch base 9 by bolts is provided inside the switch housing 4, and a micro switch 6 cooperating with the button 1 is welded on the PCB assembly 7 to realize function input. The PCB assembly 7 is provided with micro switches 6 and electrical components such as LEDs to provide working instructions for the switch, and a pin header is welded on the PCB to facilitate connection with the vehicle body line speed sheath to realize function output. A pin 8 is welded on the bottom of the PCB assembly 7 to realize function output.

[0019] In one case of this embodiment, the surface of the PCB assembly 7 is covered with a conductive rubber 5. The conductive rubber 5 is installed on the PCB board and has an interference fit with the button seat 3. When the button 1 is pressed directly, the button seat 3 drives the rubber to press down. When the stroke is satisfied, one particle of the conductive rubber 5 acts on the micro switch 6 and the other acts on the PCB board. This switch uses the micro switch 6 to realize the normally open and normally closed functions, and the particles on the PCB assembly 7 only provide force value and feel. When the external force is removed, the micro switch 6 resets under the action of its own resilience, and the elastic force of the conductive rubber 5 provides the feel and operating force of the switch.

[0020] In one case of this embodiment, a light guide 2 is disposed inside the button seat 3. The light guide 2 is provided with anti-error ribs, and cooperates with the anti-error grooves of the button seat 3. The button 1 and the button seat 3 are assembled to achieve fastening and prevent falling off.

[0021] During the implementation of this embodiment, when in the initial state, the conductive rubber 5 and the micro switch 6 are in a pre-stressed state. When the button 1 is subjected to an external force and moves downward along the guide rib, it drives the button seat 3 to move downward in the switch housing 4. When the movement corresponds to the switch stroke, the button 1 is stopped by the maximum limit of the rubber. At this time, the normally open end of the micro switch 6 is turned on, and the switch corresponding parking function signal output is realized; when the external force is removed, the conductive rubber 5 provides a rebound force to reset the button 1. When the button 1 is subjected to an external force again, it will move along the last movement trajectory. This time, the normally closed end of the micro switch 6 is turned on, and the automatic parking function is unlocked; when the external force is removed, the rubber provides a rebound force to reset the button 1 again.

[0022] The utility model is applicable to a direct-pressure button type electronic parking switch, which adopts a direct-pressure button 1, is more convenient and quick to operate, and improves driving safety. A micro switch 6 is adopted to realize the function, which saves cost. Four small-area surface contacts and four elastic structures are assembled with accessories, so that the switch can greatly weaken the abnormal noise caused by driving vibration. The contact of the elastic buffer structure is adopted to reduce the impact noise after pressing down and rebounding, and a silent gear position feeling of the switch is realized.

[0023] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.
