Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, and in particular to a car remote control key. Background Technology

[0002] A car remote key is a key that allows you to unlock or lock the car from a distance without inserting it into the keyhole. Its working principle is generally as follows: when the keypad on the remote key is pressed, triggering a microswitch underneath, the key emits a weak radio wave. This signal is received by the car's antenna, ultimately controlling the locking or unlocking of the doors.

[0003] In some existing remote control keys, in order to reduce the gap between adjacent buttons, the button panel of adjacent button structures is often a non-independent integrated button panel structure. That is, the integrated button panel is provided with multiple trigger posts for triggering the corresponding micro switches. For example, a pivot is provided at the center of the inner side wall of the integrated button panel to form a rocker-like structure, and trigger posts are provided at opposite ends of the integrated button panel. When the trigger post at one end of the button panel is pressed down by a certain stroke to trigger the corresponding micro switch, the trigger post at the other end will tilt upward by the same stroke to ensure that the two trigger posts will not trigger the corresponding micro switches at the same time.

[0004] Existing integrated keypads include two-button and four-button types. Two-button keypads have two trigger posts that can trigger two microswitches, while four-button keypads have four trigger posts that can trigger four microswitches. However, because the structures of two-button and four-button keypads are different, the housings are not interchangeable, and manufacturers need to produce multiple housings, resulting in high production costs. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the prior art by providing a car remote control key that can be adapted to the same housing, whether it is a two-button keypad or a four-button keypad, and can also prevent user errors and prevent changes to the vehicle status.

[0006] The technical solution of this utility model is as follows: A car remote control key includes an upper shell, a lower shell, and a button plate hinged to the upper shell. The upper shell and the lower shell enclose a mounting chamber for mounting a micro switch. The upper shell and the button plate enclose a mounting groove. The button plate has a pressing surface. The lower end face of the pressing surface has multiple trigger posts. The trigger posts extend into the mounting groove. The bottom of the upper shell has a through hole corresponding to the position of the trigger posts, so that when pressed, the trigger posts can enter the mounting chamber through the through hole and trigger the micro switch. The lower end face of the pressing surface also has at least one limiting post. The bottom of the upper shell has a limiting surface corresponding to the position of the limiting post, so as to limit the trigger posts from triggering the micro switch.

[0007] By adopting the above technical solution, without changing the shell structure, it can be adapted to keypads with different structures. Only different keypads need to be produced, which can meet the needs of different customers. According to the customer's needs, the corresponding keypad can be installed. Moreover, the two keypads have only minor structural differences and can be produced using the same injection mold. It can also avoid user errors and prevent changes to the vehicle's status.

[0008] A further feature of this invention is that each trigger post and limit post are integrally formed on the lower end surface of the keypad, and the distance from the trigger post to the micro switch is greater than the distance from the limit post to the limit surface.

[0009] With the above-mentioned further settings, the one-piece molded structure is robust and has good synchronization. When the pressing surface is pressed, the trigger post and the limit post move down synchronously, but the limit post will first come into contact with the limit surface, thereby restricting the contact between the trigger post and the micro switch, that is, it cannot press the micro switch.

[0010] A further feature of this invention is that the bottom of the upper shell is provided with a groove for connecting the mounting groove and the mounting chamber, and a lever is hinged in the groove. The keypad is hinged to the lever so that the keypad swings relative to the lever.

[0011] Further configuration: The lower end face of the keypad is provided with two connecting plates, the two connecting plates are provided with a first hinge hole, the toggle block is provided with a first hinge shaft that mates with the first hinge hole, the inner side wall of the slot is provided with a second hinge shaft, and the toggle block is provided with a second hinge hole that mates with the second hinge shaft.

[0012] With the above-mentioned further configuration, the keypad can swing relative to the toggle block, and the toggle block can swing relative to the housing, enabling multiple positions for pressing and activating different circuits.

[0013] A further improvement of this invention is as follows: the trigger post includes two oppositely arranged first posts and two oppositely arranged second posts, the first posts and the second posts are arranged at 90°, the two connecting plates are located between the two second posts, and the limiting posts are also provided in two, respectively located on one side of the second posts.

[0014] Further configuration: Each through hole is located on the outer periphery of the groove and is arranged in pairs opposite each other, with the first hinge shaft and the second hinge hole arranged at 90°.

[0015] With the above-mentioned further design, the button panel used in this utility model has a two-button and a four-button structure, with the two buttons arranged opposite each other, which makes the overall structure stable and prevents it from shifting when pressed. When using the two-button structure, a limiting post is set on one side of each of the two second pillars, so that when the second pillar is pressed, the second pillar cannot move down to trigger the micro switch due to the restriction of the limiting post and the limiting surface. The micro switch can only be triggered by pressing the first pillar. When using the four-button structure, there is no need to set a limiting post, and the micro switch can be triggered in four directions.

[0016] A further improvement of this utility model is that the lower end face of the upper shell is integrally formed with a baffle, the lower end of the baffle is open, and the inner side wall of the baffle is provided with a number of positioning protrusions.

[0017] With the above-mentioned further configuration, the circuit board is positioned and installed on each positioning protrusion, which makes installation convenient and ensures structural stability after installation.

[0018] A further improvement of this invention is that both the first hinge shaft and the second hinge shaft are provided with inclined surfaces.

[0019] The above-mentioned further design facilitates the insertion of the hinge shaft into the hinge hole, making the assembly and disassembly of the keypad, upper shell, and toggle convenient and quick.

[0020] A further feature of this invention is that the upper shell has a plurality of connecting hooks along its circumference, and the lower shell has a plurality of connecting slots along its circumference. Each connecting hook is engaged in the corresponding connecting slot to achieve the connection between the upper shell and the lower shell.

[0021] With the above-mentioned further design, the structure is simple, easy to install, requires no other tools, and is sturdy and not easily loosened after installation. Attached Figure Description

[0028] like Figure 1-10As shown, a car remote control key includes an upper shell 14, a lower shell 15, and a button plate 2 hinged to the upper shell 14. The upper shell 14 and the lower shell 15 enclose a mounting chamber 11 for mounting a micro switch. The upper shell 14 and the button plate 2 enclose a mounting groove 12. A circuit board can also be installed inside the mounting chamber 11. The micro switch is connected to the circuit board. The micro switch and the circuit board are prior art and will not be described in detail, nor are they shown in the accompanying drawings. The button plate 2 has a pressing surface 24, and the lower end face of the pressing surface 24 has multiple trigger posts 21, each extending into the mounting groove 12. The bottom of the upper shell 14 has through holes 121 corresponding to the positions of the trigger posts 21, so that the trigger posts 21 can pass through when pressed. The micro switch is triggered by entering the mounting chamber 11 through the through hole 121. The lower end face of the pressing surface is also provided with at least one limiting post 22. The bottom of the upper shell 14 is provided with a limiting surface 122 corresponding to the position of the limiting post 22 to limit the trigger post 21 from triggering the micro switch. With the structure of the shell 1 unchanged, it can be adapted to keypads 2 with different structures. Only different keypads 2 need to be produced to meet the needs of different customers. According to the customer's needs, the corresponding keypad 2 can be installed. Moreover, the structures of the two keypads 2 are only slightly different and can be produced using the same injection mold. When injection molding the keypad 2, the molding of the two keypads 2 can be achieved by adjusting the length of the ejector pin. It can also avoid user errors and prevent changes to the vehicle status.

[0029] Each trigger post 21 and limit post 22 is integrally formed on the lower end surface of the keypad 2. The distance from the trigger post 21 to the micro switch is greater than the distance from the limit post 22 to the limit surface 122. The integrally formed structure is sturdy and has good synchronization. When the pressing surface 24 is pressed, the limit post and the trigger post move down synchronously. The limit post 22 will first come into contact with the limit surface 142, thereby restricting the contact between the trigger post and the micro switch, that is, the micro switch cannot be pressed.

[0030] The bottom of the upper shell 14 is provided with a slot 123 for connecting the mounting groove 12 and the mounting chamber 11. A lever 3 is hinged in the slot 123. The keypad 2 is hinged to the lever 3 so that the keypad 2 can swing relative to the lever 3. The lower end face of the keypad 2 is also provided with two connecting plates 23. The two connecting plates 23 are provided with first hinge holes 231. The lever 3 is provided with a first hinge shaft 31 that mates with the first hinge hole 231. A second hinge shaft is provided on the inner side wall of the slot 123. 124, the lever 3 is provided with a second hinge hole 32 that mates with the second hinge shaft 124. The button plate 2 can swing relative to the lever 3, and the lever 3 can swing relative to the housing 1, enabling multiple positions for pressing and activating different circuits. The trigger post 21 includes two opposing first posts 211 and two opposing second posts 212. Four pressing surfaces are also provided. The first posts 211 and the second posts 212 are set at 90°. Two connecting plates 23 are located between the two second posts 211 and 212. Between 12, two limiting posts are also provided, and are respectively provided on one side of the two second posts 212; each through hole 121 is provided on the outer periphery of the slot 123, and is arranged opposite to each other in pairs.

The button plate 2 used in this utility model has a two-key and four-key structure, which is arranged opposite to each other in pairs, so that the overall structure has good stability and does not shift when pressed. When the two-key structure is used, a limiting post 22 is provided on one side of each of the two second posts 212, so that the pressing has a first limiting post 22. When the second column 212 is in position, due to the restriction of the limiting column 22 and the limiting surface 122, the second column 212 cannot move down to trigger the micro switch. The micro switch can only be triggered by pressing the first column 211. However, when a four-button structure is adopted, there is no need to set the limiting column 22, and the micro switch can be triggered in four directions. The first hinge shaft 31 and the second hinge shaft 124 are both provided with inclined surfaces, which facilitates the insertion of the hinge shaft into the hinge hole, making the disassembly and assembly of the button plate, the upper shell and the toggle block convenient and quick.

[0031] The lower end face of the upper shell 14 is integrally formed with a retaining wall 13. The bottom of the retaining wall 13 is open, and the inner side wall of the retaining wall 13 is provided with several positioning protrusions 131. The circuit board is mounted on each positioning protrusion 131 for positioning and installation, which is convenient for installation and the structure is stable after installation. The retaining wall 13 is integrally formed with the upper shell 14 and does not affect the installation of other components inside the shell 1. The open bottom of the retaining wall 13 facilitates the installation of the circuit board. Specifically, the connection between the upper shell 14 and the lower shell 15 is as follows: the upper shell 14 is provided with several connecting hooks 141 along its circumference, and the lower shell 15 is provided with several corresponding connecting slots 151 along its circumference. Each connecting hook 141 is hooked into the corresponding connecting slot 151 to realize the connection between the upper shell 14 and the lower shell 15. Of course, other connection methods can also be used, such as screw connection. This utility model adopts a snap-fit ​​connection structure, which is simple and convenient to install. No other tools are required for installation, and the structure is firm and not easy to loosen after installation. The end of the housing is provided with a hanging hole 16, which can be used to hang pendants or keys.
