Description

Technical Field

[0001] This utility model belongs to the field of automotive parts technology, and in particular relates to a clamping device for applying film to the shell of an automotive rearview mirror. Background Technology

[0002] The rearview mirror housing is the external structure that encloses the core components of the rearview mirror. Although it may seem like a "decorative part", it actually plays four core roles: protection, functional integration, appearance adaptation, and aerodynamic optimization. It is a key component in the car's exterior that combines practicality and aesthetics.

[0003] As a prominent and vulnerable component of vehicle exteriors, the rearview mirror housing is easily damaged by scratches, corrosion, and sun exposure. Window tinting can specifically address these issues. Removing the rearview mirror housing before tinting makes the process easier. To elevate and support the rearview mirror housing during tinting, a clamping device for tinting rearview mirror housings has been designed. This device uses a reaction force to apply a reverse clamping force to the inner cavity of the rearview mirror housing. This ensures the rearview mirror is supported and secured while preventing the clamp from covering the housing surface and causing inconvenience during tinting. Utility Model Content

[0004] The purpose of this utility model is to provide a clamping device for applying film to the outer shell of a car rearview mirror, which can support and fix the rearview mirror while avoiding the "clamp" covering the surface of the outer shell, thus avoiding the inconvenience of applying film to the outer shell, thereby solving the above-mentioned technical problems.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A clamping device for applying film to the shell of a car rearview mirror includes a support base: two sliders are slidably connected to the inner cavity of the support base; cylinders are welded to the front and rear sides of the inner cavity of the sliders; a ring is slidably connected to the inner cavity of the cylinder; a spring is welded between the ring and the slider; a ball is rotatably connected to the inner cavity of the ring; multiple semi-circular grooves are opened on the front and rear sides of the inner cavity of the support base; the surface of the ball is rotatably connected to the inner cavity of the semi-circular groove; a protrusion is welded to the top of each of the two sliders; an abutment plate is welded to the opposite side of each of the two protrusions; and a rubber pad is fixedly connected to the end of the abutment plate opposite to the protrusion.

[0006] Preferably, the bottom of the support base has two guide grooves, and the bottom of each of the two sliders is welded with an extension plate.

[0007] Preferably, the surface of the extension plate extends through the guide groove to the bottom of the support base, and the surface of the extension plate is welded with an edge-sealing piece.

[0008] Preferably, both the surface of the edge banding piece and the bottom of the support base are provided with screw holes, and bolts are threaded into the inner cavity of the screw holes.

[0009] Preferably, a rubber ring is slidably connected to the surface of the bolt, and a roller is installed at the bottom of the slider.

[0010] Preferably, the surface of the roller is slidably connected to the bottom of the inner cavity of the support seat.

[0011] The beneficial effects of this utility model are:

[0012] 1. This utility model allows two sliders to slide separately, thereby causing the two contact plates and rubber pads to adhere to the inner wall of the housing. This results in the rearview mirror housing being clamped and fixed in the opposite direction, thus achieving the purpose of supporting and fixing the rearview mirror while avoiding the "clamp" covering the surface of the housing, which would make it inconvenient to apply a film to the housing.

[0013] 2. By setting up the roller, this utility model can reduce the friction between the bottom of the slider and the inner wall of the support seat during the sliding of the slider in the inner cavity of the support seat, and can avoid the slider from getting blocked during sliding.

[0021] In the following description, embodiments of the clamping device for applying film to the car rearview mirror housing according to the present invention will be described with reference to the accompanying drawings.

[0022] Example 1:

[0023] Figure 1-4This invention illustrates a clamping device for applying film to the outer shell of a car rearview mirror, comprising a support base 1. Two sliders 2 are slidably connected to the inner cavity of the support base 1. Cylindrical tubes 3 are welded to the front and rear sides of the inner cavity of each slider 2. A ring 4 is slidably connected to the inner cavity of each cylinder 3. A spring 5 is welded between the ring 4 and the slider 2. A ball bearing 6 is rotatably connected to the inner cavity of the ring 4. Multiple semi-circular grooves 7 are formed on the front and rear sides of the inner cavity of the support base 1. The surface of the ball bearing 6 is rolled within the inner cavity of the semi-circular grooves 7. The tops of the two sliders 2 are welded with… The support base 1 has two protrusions 8, and two contact plates 9 are welded to the opposite sides of the two protrusions 8. A rubber pad head 10 is fixedly connected to the opposite end of the contact plate 9 and the protrusion 8. Two guide grooves 11 are opened at the bottom of the support base 1. An extension plate 12 is welded to the bottom of the two sliders 2. The surface of the extension plate 12 passes through the guide grooves 11 to the bottom of the support base 1. An edge piece 13 is welded to the surface of the extension plate 12. A screw hole 14 is opened on the surface of the edge piece 13 and the bottom of the support base 1. A bolt 15 is threaded into the inner cavity of the screw hole 14.

[0024] Example 2:

[0025] Figure 1-4 This invention illustrates a clamping device for applying film to the outer shell of a car rearview mirror, comprising a support base 1. Two sliders 2 are slidably connected to the inner cavity of the support base 1. Cylindrical tubes 3 are welded to the front and rear sides of the inner cavity of each slider 2. A ring 4 is slidably connected to the inner cavity of each cylinder 3. A spring 5 is welded between the ring 4 and the slider 2. A ball bearing 6 is rotatably connected to the inner cavity of the ring 4. Multiple semi-circular grooves 7 are formed on the front and rear sides of the inner cavity of the support base 1. The surface of the ball bearing 6 is rotatably connected to the inner cavity of the semi-circular grooves 7. A protrusion is welded to the top of each slider 2. 8. Abutment plates 9 are welded to the opposite sides of the two protrusions 8. A rubber pad head 10 is fixedly connected to the opposite end of the abutment plate 9 and the protrusion 8. A rubber ring 16 is slidably connected to the surface of the bolt 15. A roller 17 is installed at the bottom of the slider 2. The surface of the roller 17 is slidably connected to the bottom of the inner cavity of the support seat 1. By setting the roller 17, the friction between the bottom of the slider 2 and the inner wall of the support seat 1 can be reduced during the sliding of the slider 2 in the inner cavity of the support seat 1, so as to avoid the slider 2 from being blocked during sliding.

[0026] Working principle: When using this utility model, the user places the rearview mirror housing onto the surface of the support base 1. Since the rearview mirror housing is irregularly shaped, the two sliders 2 need to be slid separately. During this process, the sliding extension plate 12 drives the sliders 2 to slide. When the sliders 2 slide, the surface of the ball bearing 6 rolls against the inner wall of the support base 1. When it contacts the semi-circular groove 7, the rebound force of the spring 5 causes the ball bearing 6 to enter the inner cavity of the semi-circular groove 7, thereby initially positioning the contact plate 9 and the rubber pad head 10. Then, the bolt 15 is tightened into the inner cavity of the screw hole 14, thereby fixing the contact plate 9. Then, the above operation is performed on the other side of the slider 2, thereby causing the rubber pad head 10 to adhere to the inner wall of the housing. This allows the inner cavity of the rearview mirror housing to receive a reverse clamping and fixing force, thereby supporting and fixing the rearview mirror while avoiding the "clamp" covering the surface of the housing, which would make it inconvenient to apply the housing film.

[0027] In summary, this clamping device for applying film to the car rearview mirror housing achieves this by sliding the two sliders 2 separately, thereby causing the two contact plates 9 and the rubber pad head 10 to adhere to the inner wall of the housing. This results in a reverse clamping and fixing force on the inner cavity of the rearview mirror housing, thus supporting and fixing the rearview mirror while preventing the "clamp" from covering the surface of the housing and causing inconvenience in applying the film.
