[0028] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0029] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0030] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0031] Example

[0032] Reference Figures 1 to 5 , is an embodiment of the utility model, which provides a spare tire cover for an automobile, including a cover 100, a driving assembly 200 disposed on the cover 100, and an expansion assembly 300 connected to the driving assembly 200, wherein the driving assembly 200 includes a piston body 202 and a gas cylinder 204;

[0033] The cover plate 100 is used to cover the trunk of the car, cover the spare tire of the car, and provide a flat surface for the trunk. The driving component 200 is used to inflate or deflate the expansion component 300 and is installed on the cover plate 100. The inflation or deflation process is achieved by squeezing / extracting air from the piston body 202 in the air cylinder 204.

[0034] During inflation, the piston body 202 compresses the inner cavity of the air cylinder 204 downwards, and when the piston body 202 and the air cylinder 204 are locked, the expansion assembly 300 expands and comes into close contact with the recessed portion of the spare tire hub, and is supported between the cover plate 100 and the spare tire;

[0035] When the air is deflated, when the piston body 202 is pulled upward out of the inner cavity of the air cylinder 204, the expansion assembly 300 contracts and separates from the recessed portion of the spare tire hub;

[0036] The cover plate 100 is conveniently installed in the trunk, and the gas cylinder 204 is conveniently installed on the cover plate 100. Specifically, the cover plate 100 is provided with a handle 101 for lifting the cover plate 100. The cover plate 100 is provided with an adapting hole 102. The gas cylinder 204 is sleeved on the adapting hole 102. The gas cylinder 204 has a lip 205 at the opening, and the gas cylinder 204 is fixed to the cover plate 100 with a ring 204a sleeved on the gas cylinder 204. The lip 205 on the gas cylinder 204 is placed on the upper surface of the cover plate 100 and the cover plate 100 is clamped from the lower surface of the cover plate 100 through the ring 204a to form a three-layer structure. Then, the three are fixed by screws and other fixing parts to complete the installation of the gas cylinder 204 on the cover plate 100.

[0037] In order to realize that when the piston body 202 compresses the inner cavity of the air cylinder 204 downward during inflation, and when the piston body 202 and the air cylinder 204 are locked, the expansion assembly 300 expands and contacts closely with the recessed part of the spare tire hub, and is supported between the cover plate 100 and the spare tire, specifically, a rotary cover 201 is provided on the piston body 202, and the rotary cover 201 and the piston body 202 are connected by a shaft 201b so that the rotary cover 201 can rotate freely, a limiting member 201a is provided on the rotary cover 201, and a recess 205a is provided on the lip 205. When the piston body 202 compresses the inner cavity of the air cylinder 204 downward, the rotary cover 201 rotates, and the limiting member 201a is screwed into the recess 205a of the lip 205, and vice versa, the limiting member 201a is separated from the recess 205a;

[0038] Furthermore, the stoppers 201a are evenly distributed in an annular shape on the rotary cover 201, and the recesses 205a are evenly distributed in an annular shape on the lip 205, thereby increasing the stability of the locking;

[0039] The limiting block 201a-1 of the limiting member 201a is matched with the locking groove 205a-1 of the recess 205a. After locking, the piston body 202 is locked more stably when the vehicle is running.

[0040] In order to quickly take out the spare tire when locked and to facilitate and quickly deflate the piston body 202, specifically, a reset member 203 is provided on the piston body 202 and / or the air cylinder 204. After the piston body 202 is squeezed, the reset member 203 is used to enable the piston body 202 to move upward. The elastic potential energy of the reset member 203 can not only further increase the stability of the lock, but also allow the piston body 202 to gradually rise from the air cylinder 204, allowing the expansion assembly 300 to shrink and separate from the recessed part of the spare tire hub. The reset member 203 can be set as a magnet installed inside the air cylinder 204, and another magnet is installed on the piston body 202. The two magnets of the same polarity repel each other to generate a repulsive force, which can also be achieved by setting a spring.

[0041] Specifically, the expansion component 300 includes a main body 301, a sealing connection hole 301a and an expansion body 302. The expansion body 302 protrudes from the side of the main body 301 and cooperates with the depression of the spare tire hub. The sealing connection hole 301a is sealed with the connecting head 204b at the bottom of the air cylinder 204. The main body 301 is set not to expand in the upward and downward directions to avoid pushing out the cover plate 100. The expansion body 302 is installed on the side and fills the depression of the spare tire hub after expansion, so that the expansion component 300 forms a connection structure with the spare tire after inflation. At the same time, after the main body 301 expands, it has a supporting effect on the cover plate 100.

[0042] Importantly, it should be noted that the construction and arrangement of the present application shown in a plurality of different exemplary embodiments are only exemplary. Although only a few embodiments are described in detail in this disclosure, it should be readily understood by those who refer to this disclosure that many modifications are possible (e.g., the size, scale, structure, shape and ratio of various elements, and parameter values ​​(e.g., temperature, pressure, etc.), installation arrangements, use of materials, color, directional changes, etc.) without substantially departing from the novel teachings and advantages of the subject matter described in the application. For example, the element shown as integrally formed can be composed of multiple parts or elements, the position of the element can be inverted or otherwise changed, and the nature or number or position of the discrete element can be changed or changed. Therefore, all such modifications are intended to be included in the scope of the present utility model. The order or sequence of any process or method steps can be changed or reordered according to alternative embodiments. In the claims, any "device plus function" clause is intended to cover the structure of performing the function described herein, and is not only structurally equivalent but also equivalent structure.

Therefore, the present invention is not limited to a specific embodiment, but extends to various modifications that still fall within the scope of the appended claims.

[0043] Additionally, in order to provide a concise description of example embodiments, all features of an actual embodiment (ie, those features that are not relevant to the best mode presently contemplated for carrying out the invention or those that are not relevant to implementing the invention) may not be described.

[0044] It will be appreciated that in the development of any actual implementation, as in any engineering or design project, numerous implementation-specific decisions may be made.
