Description

Technical Field

[0001] The utility model relates to the technical field of automobile accessories, in particular to a car remote control key. Background Art

[0002] With the rapid development of the automobile industry, automobile keys have also developed rapidly, and new requirements have been placed on keys. In particular, the key force at the raised position of the button shell is relatively large. At the same time, the shell is subjected to relatively large pressure for a long time, which makes it impossible to recover after being deformed by pressure, resulting in a concave surface and affecting normal use; in addition, the shell is greatly deformed after assembly, and the size is difficult to control. A large gap is likely to appear at the installation position, which directly affects the sealing effect of the internal components; in addition, since most automobile keys are directly connected to the lower cover by buckling the upper cover, when the battery is used up, it is necessary to replace the battery. Due to the small gap at the buckling position, it is very inconvenient to open the key cover. Utility Model Content

[0040] The operating principle of the utility model is as follows:

[0041] like Figure 1 , Figure 6 to Figure 7 As shown, before the upper cover 1 and the lower cover 6 are buckled onto the lining cover 2, the control circuit board 5 is first placed in the lower cover 6, and then the limiting protrusion 44 is inserted into the limiting slot 50, and the first limiting column 45 extends into the first limiting hole 51, and the second limiting column 47 extends into the second limiting hole 52. At this time, the lower end surfaces of the first button rod 41 and the second button rod 42 are respectively abutted against the upper end surfaces of the micro switches 501 at the corresponding positions; the connecting plate 40 made of ABS material provides elastic force for the return of the button rod. At the same time, the integral connection between the button rod and the button plate 4 simplifies the problem of multi-part assembly and improves assembly efficiency.

[0042] Then, if Figures 1 to 5 As shown, a sealing gasket 3 is covered on the outer side of the key plate 4. Specifically, the mounting holes at corresponding positions are sleeved on the outer side of the key rod, and the upper end surface of the key rod at the corresponding position abuts against the bottom of the mounting hole, that is, the support sleeve 30 is sleeved on the outer side of the key rod, and the third limiting column 31 extends into the third limiting hole 53. At this time, the sealing gasket 3 covers the outer sides of the key plate 4 and the control circuit board 5, and the lower end surface of the sealing gasket 3 fits with the upper end surface of the lower cover 6, thereby covering and sealing the key plate 4 and the control circuit board 5.

[0043] Then, if Figure 1 , Figure 2 , Figure 4 , Figure 5 and Fig. 9 As shown, the inner lining cover 2 is covered on the outer side of the sealing gasket 3. Specifically, a placement hole 20 emerges from the upper end surface of the support sleeve 30 at the corresponding position, the second clamping block 22 extends into the second clearance hole 23 and the upper end surface of the second clamping block 22 is fixed with the lower end surface of the first clamping block 60 by snapping, and the first positioning plate 61 extends into the third clearance hole 24 to limit the position. At this time, the lower cover 6 is fixedly connected to the inner lining cover 2.

[0044] Then, if Figure 1 , Figure 3 , Figure 4 and Figure 8 As shown, the upper cover 1 is covered on the outer side of the inner lining cover 2. Specifically, the fixing column 10 is inserted into the fixing hole 25, the second positioning plate 11 extends into the second clearance hole 23, the third clamping block 12 extends into the clearance groove 26, and the lower end surface of the inner lining cover 2 abuts against the upper end surface of the third clamping block 12 for limiting position. At the same time, the protruding end of the support sleeve 30 abuts against the inner side wall of the upper cover 1, and the upper end surface of the support boss 27 abuts against the inner side wall of the upper cover 1. At this time, the upper cover 1 is fixedly connected to the inner lining cover 2.

[0045] The provided sealing gasket 3 and inner lining cover 2 can not only seal the control circuit board 5, but also support the non-button position of the upper cover 1, significantly improving the pressing feel of the button position; the notch 201 provided on the connecting ring 21 is convenient for prying open the connection position between the upper cover 1 and the lower cover 6, so as to quickly open the key shell; at the same time, the provided inner lining cover 2 is respectively connected with the upper cover 1 and the lower cover 6 by snapping, dispersing the connection position, and while ensuring a tight connection, it is also possible to save effort in opening the upper cover 1 and the lower cover 6 separately.

[0046] It should be noted that if Figures 1 to 3 As shown, a thin-walled section is provided at the raised position of the upper cover 1, especially at the position corresponding to the first button rod 41 and the second button rod 42. The wall thickness of the thin-walled section is preferably 0.5 mm. Under the same force, the deformation of the thin-walled section under pressure is larger, that is, at the button rod position where a larger force is required, only a smaller force is needed to meet the requirement of the button deformation while satisfying the button response. According to the factors of the finger pressing force and the pressing angle, when the pressing stroke range of the thin-walled section is 0.1 mm to 0.7 mm, the micro switch 501 can be well squeezed and the control circuit board 5 can respond, while improving the pressing feel.
