Description

Technical Field

[0001] The utility model relates to the technical field of automotive buttons, and particularly to a structure for preventing a rotary button from coming out. Background Art

[0002] In existing automotive switches, buttons that are pressed and rotated in the up and down directions are often used, such as window switches. Such buttons are usually pivotally connected to two side plates on a button mounting base and are provided with a reset structure, so that the button can rotate around a rotating shaft when the user presses or pulls it upward to realize the operation control of the corresponding structure, and can be reset by relying on the reset structure after rotation for the next operation.

[0003] During production, the inventor found that to meet the assembly requirements, the hanging amount of the button on the rotating shafts of the two side plates of the mounting base is small, and to meet the demolding requirements, the positioning bottom support of the mounting base cannot exactly cooperate with the lower end limit of the button, resulting in a gap between the lower end parts on both sides of the button and the side wall of the positioning bottom support of the mounting base; and the two side plates on the mounting base have a relatively high force-bearing height and a relatively thin wall thickness, and due to matching reasons, the side plates cannot be further strengthened, resulting in strong elasticity; when pulling the button directly, it can meet the requirement of strong stretching without the button coming off from the housing, but when pulling one side of the button (the side close to the rotating shaft), due to the strong elasticity of the two side plates, a relatively small force may cause the button to come out.

[0004] In summary, to bring a good experience to customers, the inventor designs a structure for preventing a rotary button from coming out, making it more stable during use. Content of the Utility Model

[0005] The purpose of the utility model is to overcome the defects and deficiencies existing in the prior art, and provide a structure for preventing a rotary button from coming out. The technical solution adopted by the utility model is as follows:

[0006] A structure for preventing a rotary button from coming out, including a button body and a mounting bracket. Two mounting side plates are provided in pairs on the mounting bracket, and a positioning bottom support is provided between the two mounting side plates. There is a demolding gap between the outer walls on both sides of the positioning bottom support and the two mounting side plates; the button body is pivotally connected between the two mounting side plates through button side plates on both sides thereof, and the button side plates extend into the demolding gap; an installation hole is opened at the bottom of the mounting bracket corresponding to the demolding gap, and a limit baffle penetrates into the demolding gap from bottom to top through the installation hole until it is located between the inner side wall of the button side plate and the outer side wall of the positioning bottom support to limit the inner side wall of the button side plate.

[0007] Preferably, a rotating shaft protrudes from the inner wall of the mounting side plate, and a shaft hole for the rotating shaft to pass through is opened on the button side plate.

[0008] Preferably, the mounting side plate is connected to the mounting frame via an L-shaped connecting portion, and the mounting side plate and the L-shaped connecting portion are combined to form a U-shaped structure. The outer side of the top of the limit baffle has a stepped surface, and the stepped surface and the inner wall of the mounting side plate enclose a limit cavity with three sides (left and right sides and the bottom) of the limit cavity, and the lower end of the button side plate is limited in the limit cavity.

[0009] Preferably, the limit baffle has an extended side plate, and the extended side plate extends laterally from the limit baffle toward the inner side wall of the installation side plate, so that the limit baffle and the extended side plate are laterally limited between the installation side plate and the positioning base.

[0010] Preferably, a positioning base plate is provided at one end of the limit baffle away from the button body, and the positioning base plate at least partially extends to a position below the positioning base bracket so that the positioning base bracket limits the limit baffle in the vertical direction.

[0011] Preferably, the end of the limit baffle away from the button body has a positioning base plate, the positioning base plate is arranged below the mounting hole, the limit baffle passes through the mounting hole and is located above the mounting hole, and the width of the positioning base plate is greater than the width of the mounting hole.

[0012] Preferably, a groove is provided on the positioning base plate, and a limiting protrusion cooperating with the groove is arranged around the mounting hole.

[0013] Preferably, a lower plate is provided below the mounting frame, and the positioning base plate is limited between the lower plate and the positioning base.

[0014] The beneficial effects of the utility model are as follows: the technical scheme arranges an easily installed limit baffle in the demolding gap between the positioning base and the mounting side plate of the mounting frame, so that the limit baffle fills the space of the demolding gap and limits the button side plates on both sides of the button body. When the button is pushed from one side of the button (the side close to the rotating shaft), the limit baffle will limit the button side plate to resist deformation of the button in the opposite direction of the pivot joint, thereby preventing the button body and the mounting side plate from detaching, thereby avoiding the button from falling out.

[0028] Embodiment 1

[0029] As Figures 1-9As shown in the figure, a functional module for controlling a car window includes a face cover 1. A button area 101 is provided on the face cover 1. A button and a structure for preventing the rotary button from coming out are arranged in the button area 101. The button includes a button body 2. The button body 2 is installed on an injection-molded mounting bracket 3. Two mounting side plates 31 are arranged in pairs on the mounting bracket 3, and there is a positioning base 32 between the two mounting side plates 31. There is a demolding gap between the outer walls of both sides of the positioning base 32 and the two mounting side plates 31. In this embodiment, the top of the mounting side plate is 1.1 mm thick, the root is 1.3 mm thick, and the stress height is 11.2 mm. When pulling the button directly, it can withstand more than 110 N stably.

[0030] The button body 2 is pivotally connected between the two mounting side plates 31 through button side plates 21 on both sides thereof. The button side plates 21 extend into the demolding gap. An installation hole 301 is opened at the bottom of the mounting bracket 3 corresponding to the demolding gap. The limit baffle 4 penetrates into the demolding gap from bottom to top through the installation hole 301 until it is located between the inner side wall of the button side plate 21 and the outer side wall of the positioning base 32 to limit the inner side wall of the button side plate 21.

[0031] A rotating shaft 311 protrudes from the inner wall of the mounting side plate 31. A shaft hole for the rotating shaft 311 to pass through is opened on the button side plate 21. In this embodiment, the hanging amount between the button side plate and the rotating shaft is (0.99 - 1.06) mm on one side, and the rotating shaft basically does not protrude from the shaft hole.

[0032] The mounting side plate 31 is connected to the mounting bracket 3 through an L-shaped connecting part 33. The mounting side plate 31 and the L-shaped connecting part 33 form a U-shaped structure, so that there is a gap between the mounting side plate 31 and the mounting bracket 3 for the button housing to be embedded.

[0033] Refer to Figure 7 , a stepped surface 41 is provided on the outer side of the top end of the limit baffle 4. The stepped surface 41 and the inner wall of the mounting side plate 31 enclose a limit cavity with three-sided (left, right, and lower sides) limits. The lower end of the button side plate 21 is limited in the limit cavity.

[0034] Furthermore, the limit baffle 4 has an extended side plate 42. The extended side plate 42 extends horizontally from the limit baffle 4 towards the inner side wall of the mounting side plate 31, so that the limit baffle 4 and the extended side plate 42 are horizontally limited between the mounting side plate 31 and the positioning base 32.

[0035] Further, a positioning base plate 43 is provided at one end of the limit baffle 4 away from the button body 2. The positioning base plate 43 is disposed below the mounting hole 301, and at least part of the positioning base plate 43 extends to a position below the positioning base support 32 to vertically limit the limit baffle 4 by the positioning base support 32. The limit baffle 4 passes through the mounting hole 301 and is located above the mounting hole 301. The width of the positioning base plate 43 is greater than the width of the mounting hole 301. A groove is formed on the positioning base plate 43, and a limit protrusion 34 cooperating with the groove is arranged around the mounting hole 301.

[0036] Further, to make the cooperation between the limit baffle 4 and the mounting bracket more stable, in this embodiment, a positioning protrusion 44 is further provided on the extending side plate, so that the positioning protrusion 44 is in positioning cooperation with other structures inside the mounting bracket or abuts against other structures of the mounting bracket to prevent the limit baffle from shaking.

[0037] Finally, a lower plate 5 is arranged below the mounting bracket 3, so that the positioning base plate 43 is limited between the lower plate 5 and the positioning base support 32 of the mounting bracket.

[0038] The above-disclosed are only the preferred embodiments of the present invention. Of course, the scope of the rights of the present invention cannot be limited thereby. Therefore, equivalent changes made according to the claims of the present invention still fall within the scope covered by the present invention.
