[0028] To make the above-mentioned objects, features, and advantages of the present invention more clearly understood, the following detailed description of specific embodiments of the present invention is provided in conjunction with the accompanying drawings. The following description sets forth many specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art may make similar modifications without violating the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0029] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly attached to the other element or there may be an intermediate element. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be an intermediate element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only implementation methods.

[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0031] like Figure 1-4As shown, a motorcycle seat backrest provided in this embodiment includes a mounting rod frame 1, a rear frame 2, a backrest structure 3 and a limiting structure 4.

[0032] See also Figure 1 and Figure 3 The mounting rod frame 1 is installed on the rear side of the motorcycle seat, and side frame rods 11 are respectively provided at both ends of the mounting rod frame 1. The mounting rod frame 1 and the two side frame rods 11 are integrally formed to improve the structural strength. The two side frame rods 11 are parallel to each other and are respectively located on both sides of the motorcycle seat, and the front ends of the two side frame rods 11 extend toward the front side of the motorcycle.

[0033] Both ends of the rear frame 2 are respectively provided with vertical rods 21 that bend downward and extend. The two vertical rods 21 are integrally formed with the rear frame 2 to improve the structural strength. The bottom ends of the two vertical rods 21 are respectively provided with sliding sleeves 22. The two sliding sleeves 22 are respectively slidably mounted on the two side frame rods 11. By moving the sliding sleeves 22, the distance between the rear frame 2 and the passenger can be changed as a whole.

[0034] like Figure 1 As shown, in one embodiment, mounting blocks 12 are respectively provided on the inner sides of the mounting rod frame 1 and the two side frame rods 11. The mounting blocks 12 can be connected to the motorcycle body. It can be understood that the mounting blocks 12 can be connected to the motorcycle body by bolts or fixed to the motorcycle body by welding. The side wall of the sliding sleeve 22 is provided with a through hole 221 for the mounting block 12 to pass through, so as to avoid the mounting block 12 interfering with the movement of the sliding sleeve 22.

[0035] The backrest structure 3 is installed between the two upright poles 21 .

[0036] See also Figure 1 Specifically, the two uprights 21 are each provided with a sliding groove 213 on one side thereof. The backrest structure 3 comprises a back panel 31, a back cushion 32, and a slide plate 33. The back cushion 32 is mounted on the front side of the back panel 31 to provide back cushioning for the occupant, enhancing comfort. Two slide plates 33 are provided on either side of the back panel 31 and are longitudinally slidably connected to the two sliding grooves 213. By sliding the slide plates 33 longitudinally, the overall height of the backrest structure 3 can be adjusted to move the back cushion 32 to the most comfortable position for the occupant, enhancing the user experience. It should be noted that the slide plates 33 have damping within the sliding grooves 213, allowing them to remain stationary within the sliding grooves 213 when no external force is applied, making them easy to adjust at any time.

[0037] The limiting structure 4 can allow or prevent the two uprights 21 from moving toward the rear side of the motorcycle. When the rider moves the sliding sleeve 22 to a suitable position, the uprights 21 can be limited by the limiting structure 4 so that when the rider leans against the backrest structure 3, the uprights 21 will not be forced to move backward, thereby providing sufficient supporting force.

[0038] See also Figure 1-Figure 4 In one embodiment, the tops of both side frame bars 11 are formed with strip grooves 111 extending along their lengths. The bottoms of both upright bars 21 are formed with control grooves 211 connected to the inner ring of the sliding sleeve. A notch 212 is formed on the outer sides of the upright bars 21 and connected to the control grooves 211. The limiting structure 4 includes an oblique rack 41 and a shift lever 42. The two oblique racks 41 are respectively disposed within the two strip grooves 111, and each of the oblique teeth of the oblique rack 41 is inclined toward the front of the motorcycle. The two shift levers 42 are respectively slidably mounted within the control grooves 211. The bottoms of the shift levers 42 are provided with latching teeth 421, which are inclined toward the rear of the motorcycle. A spring 422 is connected between the top of the shift lever 42 and the top wall of the control groove 211. The spring 422 provides an elastic force to push the shift lever 42 downward. A shift tab 423 is provided on one side of the shift lever 42, extending beyond the notch 212.

[0039] When the vertical rod 21 is pushed toward the rear side of the motorcycle, the latch tooth 421 will be pressed against the other side of a certain bevel tooth on the bevel rack 41 and cannot move, thus realizing the one-way limit of the vertical rod 21. The passenger can directly pull the vertical rod 21 toward himself to adjust the distance between the backrest structure 3 and the back, which is convenient to operate. If the passenger is large, the two paddles 423 can be pushed upward at the same time to make the latch tooth 421 away from the bevel rack 41, thereby canceling the movement restriction of the vertical rod 21 and facilitating the front and rear adjustment of the vertical rod 21.

[0040] The utility model utilizes the vertical rod 21 to move forward and backward on the side frame rod 11 to adjust the distance between the backrest structure 3 and the passenger, enabling adaptive adjustment based on the user's body shape, thereby improving passenger comfort. Furthermore, the backrest structure 3 can be adapted to the passenger's back, keeping the passenger as close to the driver as possible, thereby aligning the vehicle's center of gravity and improving passenger safety. The limiting structure 4 can unidirectionally restrict the movement of the vertical rod 21, facilitating operation and adjustment.

[0041] Since the passenger will apply a backward thrust to the entire vertical rod 21 when leaning against the backrest structure 3, in order to increase the supporting force of the backrest and improve product safety, it is preferred that the rear sides of the two vertical rods 21 are respectively provided with supporting diagonal rods 214, and the bottom ends of the supporting diagonal rods 214 are in contact with the top surface of the side frame rod 11.

[0042] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some or all of the technical features therein. These modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the various embodiments of the present invention, and they should all be included in the scope of the claims and description of the present invention.
