Description

Technical Field

[0001] The utility model relates to the technical field of vehicle accessories, and more specifically, to a switch fixing structure. Background Art

[0002] Automobile electrical switches are mainly arranged at the instrument panel and interior trim panel positions that are easy for the driver and passengers to operate. It is required that the switch is closely and reliably fitted with the interior trim panel. Usually, the switch part is fixed by means of snap connection and screw connection.

[0003] However, the current fixing of the switch part has the following disadvantages: When using the screw connection fixing structure, it is necessary to control the tightening torque of the screw to ensure the tightening torque and avoid loosening. The layout space of the screw and the assembly tool needs to be considered in the structural design, and the installation is cumbersome; When using the snap connection fixing structure, due to the limitation of material deformation, the requirement for the fitting accuracy is high. During the assembly process, forces are applied in both the transverse and longitudinal directions of the fitting parts. The tightness of the fit depends on the control of material deformation under interference fit. Therefore, in the high and low temperature and strong amplitude environment of the vehicle, the snap-connected interior structure is prone to looseness and gap phenomena.

[0004] In view of this, the applicant has specifically proposed this application after studying the existing technologies. Summary of the Utility Model

The panel is provided with a cavity suitable for installing the fixing base, and the fixing base is provided with an inner cavity for installing the switch part; Elastic parts that can rotate relative to the fixing base are symmetrically arranged on both sides of the fixing base. One side of the elastic part passes through the fixing base and extends into the inner cavity. When the switch part is installed into the inner cavity, the outer side wall of the switch part can abut against one side of the elastic part and make it rotate downward, so that the other end of the elastic part rotates upward and can abut against the panel.

[0007] As a further optimization, the elastic part includes a shaft part as the rotating end, a first abutting part close to the inner cavity side and capable of abutting against the switch part, and a second abutting part far from the inner cavity side and capable of abutting against the panel; The elastic part is provided in a convex shape.

Specific embodiments

[0024] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model. Therefore, the following detailed description of the embodiments of the present utility model provided in the accompanying drawings is not intended to limit the scope of the present utility model to be protected, but merely represents the selected embodiments of the present utility model. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] As shown by Figures 1 to 6 the embodiments of the present utility model provide a switch fixing structure for an electrical switch component 3 in a vehicle, including a panel 2, a fixed base 1, and a switch component 3. The panel 2 is provided with a hole cavity 4 suitable for installing the fixed base 1. Among them, in this embodiment, an extension is formed by extending the upper end of the fixed base 1 outward, so that when the main body of the fixed base 1 is adapted to be installed in the hole cavity 4, it is limited on the panel 2 through this extension. The fixed base 1 is provided with an inner cavity 5 for installing the switch component 3. Among them, in this embodiment, the upper and lower ends of the inner cavity 5 are open, so that the switch component 3 can be installed on the fixed base 1 from top to bottom, and the lower end of the switch component 3 can be used for electrical connection with the vehicle.

[0026] Preferably, elastic members 6 that can rotate relative to the fixed base 1 are symmetrically arranged on both sides of the fixed base 1. One side of the elastic member 6 passes through the fixed base 1 and extends into the inner cavity 5. When the switch member 3 is inserted into the inner cavity 5, the outer sidewall of the switch member 3 can abut against one side of the elastic member 6 and cause it to rotate downward, so that the other end of the elastic member 6 rotates upward and can abut against the panel 2. In this embodiment, the elastic member 6 includes a shaft portion 7 as a rotating end, a first abutting portion 8 near the inner cavity 5 and capable of abutting against the switch member 3, and a second abutting portion 9 away from the inner cavity 5 and capable of abutting against the panel 2. A lever structure is formed between the shaft portion 7 and the fixed base 1. When the switch member 3 is inserted into the fixed base 1 from top to bottom, the switch member 3 will press down the first abutting portion 8 located in the inner cavity 5, causing the second abutting portion 9 to rotate upward until it abuts against the lower end of the panel 2. When the switch member 3 is further moved downward, the elastic member 6 will deform, thereby gradually increasing the force exerted by the first abutting portion 8 against the sidewall of the switch member 3. Finally, when the installation is completed, the two elastic members 6 symmetrically arranged on both sides of the inner cavity 5 form a lever arm inside and outside. The force longitudinally exerted by the second abutting portion 9 against the lower end of the panel 2 is converted into a stable pressing torque exerted by the first abutting portion 8 on the switch member 3, thereby fastening the switch member 3 to the fixed base 1 to complete the installation. The structure is simple and the installation is convenient. Even when the material of the vehicle panel 2 deforms due to temperature difference or under strong amplitude conditions, the elasticity of the elastic member 6 can always provide a stable pressing torque, further ensuring the fastening effect of the installation.

[0027] Among them, in order to axially limit the switch member 3 on the fixed base 1, a head portion 10 is radially outwardly extended at the head end of the switch member 3; a limiting platform 11 adapted to receive the head portion 10 is provided on the inner sidewall of the inner cavity 5. The head portion 10 of the switch member 3 is received by the limiting platform 11 for axial limitation.

[0028] Preferably, the elastic member 6 is provided in a convex shape. By setting the elastic member 6 in a convex shape, the contact length or area of the ends of the first abutting portion 8 and the second abutting portion 9 for abutting can be increased, so that the pressing and fitting of the switch member 3 is more stable.

[0029] Preferably, an installation groove 12 for installing the elastic member 6 is recessed on the outer sidewall of the fixed base 1. The installation groove 12 is horizontally arranged and communicated with the inner cavity 5 and provided with an opening 13; the shaft portion 7 is installed in the installation groove 12 so that the first abutting portion 8 extends into the inner cavity 5 from the opening 13. By providing the installation groove 12 and the separately configured elastic member 6, the installation, disassembly or replacement can be simpler. At the same time, in the way of assembly connection of the elastic member 6, the production of the fixed base 1 and the elastic member 6 can be made simpler, reducing the production cost. Further, the elastic member 6 is provided in a bent shape, so that after the elastic member 6 is inserted into the installation groove 12, its shaft portion 7 can be relatively stably maintained at a position close to the bottom of the installation groove 12, and the bent shape can also more conveniently generate a pressing torque.

[0030] Preferably, guiding grooves 14 communicating with the installation groove 12 are longitudinally arranged on both sides of the installation groove 12. By providing the guiding grooves 14, the second abutting portion 9 can be matched during rotation, so as to be limited in the radial direction to ensure stability. At the same time, the guiding grooves 14 can also limit the flipping angle of the elastic member 6.

[0031] Preferably, a pressing groove 15 is arranged on the side wall of the inner cavity 5, and the pressing groove 15 is communicated and arranged at the lower end of the opening 13. The pressing groove 15 is matched with the first abutting portion 8 to further limit it, so that the elastic member 6 can only perform a flipping action. The pressing groove 15 can also provide a flipping space for the first abutting portion 8 when the switch member 3 is fitted into the fixed base 1.

[0032] Preferably, a sleeve 16 is arranged at the end of the second abutting portion 9, and the sleeve 16 is made of PVC material to increase the friction force between the elastic member 6 and the contact end of the panel 2.

[0033] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, various changes and modifications can be made to the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
