[0014] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. The following description, with reference to the accompanying drawings, is provided to aid in understanding exemplary embodiments of the present invention as defined by the claims and their equivalents. It includes various specific details to aid understanding, but these are to be considered exemplary only. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of the present invention. Furthermore, detailed descriptions of functions and structures well known in the art will be omitted to make the specification clearer and more concise.

[0015] like Figure 1-6 As shown, a quick-release motorcycle backrest tail rack includes a connector 1 fixed to the motorcycle body. The connector 1 includes an upper bearing surface 11 and a rear bearing surface 12, which are perpendicular to each other and intersect to form an L-shaped structure. The connector 1 has several quick-release connection holes 2 at the intersection of the upper bearing surface 11 and the rear bearing surface 12, and locking movable parts 3 are provided at both ends of the connector 1. It also includes a backrest body 4, and a backrest connecting part 41 is provided at the bottom of the backrest body 4. The connecting part 41 is provided with a plurality of quick-release connecting posts 5; the top ends of the two ends 410 of the backrest connecting part 41 are provided with first locking fixing parts 61, and the rear ends of the ends 410 are provided with second locking fixing parts 62; when the quick-release connecting post 5 is inserted forward into the quick-release connecting hole 2, the locking movable part 3 is connected to the second locking fixing part 62; when the backrest body 4 is flipped so that the quick-release connecting post 5 is inserted downward into the quick-release connecting hole 2, the locking movable part 3 is connected to the first locking fixing part 61.

[0016] The backrest connection part 41 includes a top plate 411 and a back plate 412. A plurality of quick-release connecting posts 5 are fixedly installed below the top plate 411. The first locking fixing part 61 is provided at both ends of the top plate 411, and the second locking fixing part 62 is provided at both ends of the back plate 412.

[0017] The quick-release connection hole 2 includes an upper quick-release hole 211 located at the rear edge of the upper bearing surface 11, an upper limit hole 212 located in front of the upper quick-release hole 211, a rear quick-release hole 221 located at the top edge of the rear bearing surface 12, and a rear limit hole 222 located below the rear quick-release hole 221; the upper quick-release hole 211 is connected to the upper limit hole 212 and the rear quick-release hole 221 respectively, and the rear quick-release hole 221 is connected to the rear limit hole 222 and the upper quick-release hole 211 respectively.

[0018] The width of the upper quick-pass hole 211 is greater than the width of the upper limit hole 212, and the width of the rear quick-pass hole 221 is greater than the width of the rear limit hole 222.

[0019] The diameter of the quick-release connecting post 5 is greater than the width of the upper limit hole 212 and the rear limit hole 222, and the diameter of the quick-release connecting post 5 is less than the width of the upper quick-penetration hole 211 and the rear quick-penetration hole 221.

[0020] The quick-release connecting post 5 has a reduced diameter section 51 in the middle, and the diameter of the reduced diameter section 51 is smaller than the width of the upper limit hole 212 and the rear limit hole 222.

[0021] According to the quick-release motorcycle backrest and tail rack described in this application, when the backrest body 4 is upright and used as a backrest, the quick-release connecting post 5 is inserted forward into the quick-release connecting hole 2, and the reduced diameter part 51 is inserted into the upper limit hole 212, restricting the vertical movement between the top plate 411 and the upper bearing surface 11. At the same time, the locking movable part 3 is connected to the second locking fixing part 62, fastening the rear plate 412 and the rear bearing surface 12 and restricting their forward and backward movement, so that the backrest body 4 can stand firmly on the connector 1 as a backrest. During disassembly, the locking movable part 3 is opened, and the quick-release connecting post 5 is moved backward into the upper quick-release hole 211, which allows the backrest body 4 and the connector 1 to separate.

[0022] According to the quick-release motorcycle backrest / tail rack described in this application, when the backrest body 4 is laid flat and used as a motorcycle rear rack / tail rack, the backrest body 4 flips over and drives the quick-release connecting post 5 downward into the quick-release connecting hole 2. The reduced diameter part 51 is inserted into the rear limiting hole 222, restricting the forward and backward movement between the top plate 411 and the rear bearing surface 12; at this time, the backrest body 4 also has no space to move downward. At the same time, the locking movable part 3 is connected to the first locking fixing part 61, further securing the top plate 411 and the rear bearing surface 12, preventing the backrest body 4 from flipping over. During disassembly, the locking movable part 3 is opened, and the quick-release connecting post 5 is moved upward into the rear quick-release hole 221, which allows the backrest body 4 and the connecting part 1 to separate.

[0023] Special note: Regarding the quick-release motorcycle backrest and tail rack described in this application, the positional descriptions of bottom, top, and rear ends are based on the orientation of the backrest body when it is installed at the rear of the motorcycle and in a vertical position, to clearly express the relative positional relationships. However, since this product has a conversion function, when the backrest body 4 is flipped to be used as a tail rack (i.e., the backrest body is in a horizontal position), its actual position after the conversion should be understood in conjunction with the accompanying drawings of this application.

[0024] The quick-release motorcycle rear rack described in this application uses a latch, also known as a buckle, which is a component used to fasten two items. It consists of a movable part and a fixed part, achieving opening and closing through engagement and disengagement. It features vibration damping and reusability. Its working principle is based on the lever principle; pressing the lever towards the base generates a locking force, and the force is released when the lever is vertically returned to its original position, allowing for separation. Alternatively, existing stainless steel tailgate locks, electric vehicle trunk locks, etc., can be directly used, selecting appropriate sizes and specifications. However, the fixed part of the latch needs to be two pieces, used in conjunction with one movable part.

[0025] The quick-release motorcycle backrest / tail rack described in this application enables quick removal and functional conversion of the backrest, facilitating rapid removal or conversion of functions. When laid flat, it can be used as a motorcycle rear rack / tail rack; when upright, it can be used as a backrest. The structure is simple and reliable, and the function conversion method is convenient.

[0026] The present invention has been described in detail above. Specific examples have been used to illustrate the principle and implementation of the present invention. The description of the above embodiments is only for the purpose of helping to understand the method and core idea of ​​the present invention. At the same time, for those skilled in the art, there will be changes in the specific implementation and application scope based on the idea of ​​the present invention. Therefore, the content of this specification should not be construed as a limitation of the present invention.

[0027] Through the above description of the embodiments, those skilled in the art can clearly understand that this utility model is implementable. Of course, the situations listed above are merely examples, and this utility model is not limited thereto. Those skilled in the art should understand that other modifications or simplifications of the technical solutions of this utility model can be appropriately applied to this utility model and should be included within the scope of this utility model.
