[0001] This utility model belongs to the field of automotive protection technology, and more specifically, it relates to an external automotive rear cover protection device. Background Technology

[0002] It acts as a buffer layer when a vehicle is involved in a collision or scratch, reducing the damage to the rear cover, preventing wear and tear on the paint during loading and unloading, and extending the lifespan of the cover. In terms of decoration, the rich variety of styles and colors can satisfy the diverse aesthetics of car owners and enhance the vehicle's recognizability. In addition, it can temporarily cover up rear imperfections and maintain the overall appearance of the vehicle, making it a powerful choice for car owners to protect their beloved cars. Existing external car rear cover protection devices are fixed by adhesive during installation, which needs to be firmly fixed to prevent them from falling off in the event of a collision. The adhesive is very sticky, making it difficult to remove after replacement. Therefore, an external car rear cover protection device is proposed. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides an external automotive rear cover protection device. By injecting a solvent into the valve body, the adhesive layer loses its stickiness, making the buffer pad easy to remove. This solves the problem mentioned in the background technology that during installation, the adhesive method needs to be firmly fixed to prevent it from falling off in the event of a collision, and the adhesive has a high viscosity, making it difficult to remove after replacement.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an external automotive rear cover protection device, comprising a buffer pad, an mounting groove on the inner side of the buffer pad, a retainer fixed on the inner side of the mounting groove, a cavity inside the retainer, multiple first through slots on the side of the retainer away from the buffer pad, an adhesive layer fixed on the side of the retainer away from the buffer pad, multiple second through slots on the outer side of the adhesive layer, two valve bodies embedded inside the buffer pad, each valve body comprising two small pillars and one large pillar, each of the two small pillars having a first connecting slot inside, the large pillar having a second connecting slot inside, a diaphragm fixed on the inner side of the second connecting slot, and the buffer pad comprising a buffer layer, a waterproof layer, and a tear-resistant layer.

[0005] As a preferred embodiment of this invention, the interior of the first through groove is connected to the interior of the cavity.

[0006] As a preferred embodiment of this invention, the depth of the mounting groove is equal to the sum of the thicknesses of the adhesive layer and the retainer.

[0007] As a preferred embodiment of this invention, the positions of the plurality of second through slots correspond to the positions of the plurality of first through slots.

[0008] In a preferred embodiment of this invention, the interior of the first communicating groove is connected to the interior of the cavity.

[0009] As a preferred embodiment of this utility model, the interior of the second connecting groove is connected to the interior of the two first connecting grooves.

[0010] As a preferred embodiment of this invention, the retainer is made of a rigid material.

[0011] This utility model provides an external vehicle rear end cover protection device, which has the following beneficial effects:

[0012] This external rear-end cover protection device allows for the replacement of the bumper pad by injecting a solvent into the first connecting groove of one of the valve bodies. The solvent then enters the second connecting groove through the first connecting groove and is forced through the diaphragm by pressure. Afterward, it enters the cavity inside the retainer. The solvent passes through the first through groove on the cavity, thereby contacting the adhesive layer and causing it to lose its adhesiveness. This makes the bumper pad easy to remove, solving the problem that during installation, the adhesive method requires a firm fixation to prevent it from falling off in the event of a collision, and the adhesive has a high viscosity, making it difficult to remove after replacement.

[0013] 2. This external vehicle rear cover protection device, by setting a diaphragm in the valve body, can effectively block external air from entering the cavity of the retainer through the first and second connecting grooves on the valve body, and prevent moisture in the air from contacting the adhesive layer through the first connecting groove on the cavity, thereby reducing the life of the adhesive layer.

[0021] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0022] In the description of this utility model, unless otherwise stated, "a plurality of" means two or more; the terms "upper," "lower," "left," "right," "inner," "outer," "front end," "rear end," "head," "tail," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. In addition, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0023] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0024] Please see Figures 1 to 6This utility model provides a technical solution: an external automotive rear-end cover protection device, including a buffer pad 1. An installation groove 2 is formed on the inner side of the buffer pad 1. A retainer 3 is fixed inside the installation groove 2. A cavity 4 is formed inside the retainer 3. Multiple first through grooves 5 are formed on the side of the retainer 3 away from the buffer pad 1. An adhesive layer 6 is also fixed on the side of the retainer 3 away from the buffer pad 1. Multiple second through grooves 7 are formed on the outer side of the adhesive layer 6. Two valve bodies 8 are embedded inside the buffer pad 1. Each valve body 8 includes two small pillars 801 and one large pillar 802. A first connecting groove 80 is formed inside each of the two small pillars 801. 3. The interior of the large column 802 is provided with a second connecting groove 804. A diaphragm 9 is fixed inside the second connecting groove 804. The buffer pad 1 includes a buffer layer 101, a waterproof layer 102 and a tear-resistant layer 103. The interior of the first through groove 5 is connected to the interior of the cavity 4. The depth of the mounting groove 2 is equal to the sum of the thicknesses of the adhesive layer 6 and the retainer 3. The positions of the multiple second through grooves 7 correspond to the positions of the multiple first through grooves 5 respectively. The interior of one of the first connecting grooves 803 is connected to the interior of the cavity 4. The interior of the second connecting groove 804 is connected to the interiors of the two first connecting grooves 803. The retainer 3 is made of rigid material.

[0025] The buffer pad 1 is fixed to the rear of the car by the adhesive layer 6. In the event of a collision, the buffer layer 101 in the buffer pad 1 absorbs the impact. At the same time, the tear-resistant layer 103 effectively reduces the possibility of the buffer layer 101 being torn by external forces. When the buffer pad 1 needs to be replaced, a solvent is injected into the first connecting groove 803 of one of the valve bodies 8. The solvent enters the second connecting groove 804 through the first connecting groove 803 and is forced through the diaphragm 9 by pressure. Then, it enters the cavity 4 in the retainer 3. The solvent comes into contact with the adhesive layer 6 through the first through groove 5 on the cavity 4, causing the adhesive layer 6 to lose its adhesiveness, making the buffer pad 1 easy to remove. This solves the problem that when it is fixed by adhesive during installation, it needs to be firmly fixed to prevent it from falling off in the event of a collision. The adhesive has a high viscosity, which makes it difficult to remove after replacement.

[0026] The specific usage and function of this embodiment: This utility model fixes the buffer pad 1 to the rear of the car through the adhesive layer 6. In the event of a collision, the buffer layer 101 in the buffer pad 1 absorbs the impact. At the same time, the tear-resistant layer 103 effectively reduces the possibility of the buffer layer 101 being torn by external force. When the buffer pad 1 needs to be replaced, a solvent is injected into the first connecting groove 803 of one of the valve bodies 8. The solvent enters the second connecting groove 804 through the first connecting groove 803 and breaks through the barrier of the diaphragm 9 by pressure. Then, it enters the cavity 4 in the retainer 3. The solvent comes into contact with the adhesive layer 6 through the first through groove 5 on the cavity 4, causing the adhesive layer 6 to lose its adhesiveness, making it easy to remove the buffer pad 1.

[0027] By setting a diaphragm 9 in the valve body 8, external air can be effectively blocked from entering the cavity 4 of the retainer 3 through the first connecting groove 803 and the second connecting groove 804 on the valve body 8, thus preventing the moisture in the air from contacting the adhesive layer 6 through the first connecting groove on the cavity 4, thereby reducing the life of the adhesive layer 6.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
