Abstract
Description
Technical Field
[0001] This utility model belongs to the field of motorcycle technology, and more specifically, it is an electrically adjustable motorcycle backrest. Background Technology
[0002] Traditional motorcycle backrests are fixed, and the average rider cannot lean against the backrest located at the rear. Only when multiple people are riding can the rear passenger lean against the backrest. This reduces the riding comfort of a single rider. If the motorcycle backrest could be flexibly adjusted to meet the leaning needs of single or multiple riders, the riding comfort of the motorcycle would be improved. Utility Model Content
[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an electrically adjustable motorcycle backrest that can adjust the front and back position and angle of the backrest according to the number of riders and different leaning needs, thereby improving the flexibility and comfort of the backrest.
[0004] This utility model provides the following technical solution: an electrically adjustable backrest for a motorcycle, including a motorcycle body, a seat and a rear support mounted on the motorcycle body, the backrest being mounted on the rear support, and the rear support being movable forward and backward on the motorcycle body via a translation mechanism, wherein when the translation mechanism electrically controls the rear support to move forward and backward, the backrest moves forward and backward to a certain position above the seat for leaning; the backrest is rotatably mounted on the rear support via a rotation mechanism, wherein when the rotation mechanism electrically controls the backrest to rotate, the angle is changed for leaning.
[0005] As an improvement, the translation mechanism includes a lower rail, an upper rail, a first motor, and a first drive shaft. There are two sets of lower rails installed on both sides of the motorcycle body. The upper rail is set on the lower rails to cooperate and perform forward and backward translation. The first motor is set between the two sets of lower rails. The first drive shaft extends from the first motor to both sides to the upper rails, and the first drive shaft and the upper rail are connected and driven by a transmission structure.
[0006] As an improvement, the rotating mechanism includes a fixed frame, a rotating frame, a second motor, and a second drive shaft. There are two sets of fixed frames installed on both sides of the rear support. The rotating frames are installed on both sides of the backrest. The rotating frames are rotatably mounted on the fixed frames on both sides. The second motor is located on one side of the fixed frame. The second drive shaft extends from the second motor to the rotating frames on both sides. The second drive shaft and the rotating frame are driven by a transmission structure.
[0007] As an improvement, the motorcycle body is equipped with mounting brackets on both sides, and a mounting plate extends downward from the lower rail. The mounting plate and mounting bracket are provided with several mounting holes for corresponding installation and are fixed by fasteners.
[0008] As an improvement, an installation platform is formed on the upper surface of the rear bracket.
[0009] The beneficial effects of this invention are as follows: The backrest can be moved forward and backward via an electric button, allowing the rider to lean against it when riding alone, and to move behind the passenger when there is another passenger, thus improving the flexibility of the backrest when there are different numbers of passengers. The backrest angle can also be adjusted via an electric button, allowing the person leaning against it to adjust the backrest to a comfortable angle according to their height and body type, thereby improving the comfort of leaning against it. Attached Figure Description
[0010] Figure 1 This is a three-dimensional structural diagram of a portion of the motorcycle according to the present invention.
[0011] Figure 2 This is a three-dimensional structural diagram of the motorcycle after the rear support has been partially removed according to this utility model. Detailed Implementation
[0012] The specific embodiments of this utility model are described in detail below with reference to the accompanying drawings.
[0013] like Figure 1 , 2 The image shows a specific embodiment of the electrically adjustable motorcycle backrest of this utility model. This embodiment includes a motorcycle body 1, a seat 2 mounted on the motorcycle body 1, and a rear support 3. A backrest 4 is mounted on the rear support 3. The rear support 3 is movable forward and backward on the motorcycle body 1 via a translation mechanism 5. When the translation mechanism 5 electrically controls the rear support 3 to move forward and backward, the backrest 4 moves forward and backward to a position above the seat 2 for leaning. The backrest 4 is rotatably mounted on the rear support 3 via a rotation mechanism 6. When the rotation mechanism 6 electrically controls the backrest 4 to rotate, the angle changes for leaning.
[0014] In use, the seat 2 and the rear support 3 are positioned opposite each other at the front and rear of the motorcycle body 1. The rear support 3 can be moved forward by activating the translation mechanism 5, thus reaching a position above the seat 2. The motorcycle seat 2 is generally designed for two people, one driver in front and one passenger in the back. If the passenger is small, three people can squeeze in. Taking two people as an example, the forward position of the rear support 3 is such that one person can lean against the backrest 4, and the rear position is such that one person can lean against the backrest 4 when two people are sitting. The electric buttons of the translation mechanism 5 and the rotation mechanism 6 are preferably located at the front of the motorcycle for easy adjustment by the driver before riding. After adjusting the front and rear position of the rear support 3, the position of the backrest 4 is determined. The passenger can activate the rotation mechanism 6 to adjust the front and rear angle of the backrest 4 according to their own comfort, which improves the flexibility and comfort of the backrest 4 and makes it more suitable for single-person driving.
[0015] As an improved specific implementation, the translation mechanism 5 includes a lower rail 51, an upper rail 52, a first motor 53, and a first drive shaft 54. The lower rail 51 consists of two sets and is installed on both sides of the motorcycle body 1. The upper rail 52 is set on the lower rail 51 to cooperate and perform forward and backward translation. The first motor 53 is set between the two sets of lower rails 51. The first drive shaft 54 extends from the first motor 53 to both sides to the upper rail 52, and the first drive shaft 54 and the upper rail 52 are connected and driven by a transmission structure.
[0016] like Figure 2 As shown, the upper rail 52 is smoothly positioned via the lower rails 51 installed on both sides, allowing for smooth forward and backward movement of the upper rail 52. The rear bracket 3 is mounted on the upper rail 52. The first motor 53 can be mounted on the rear bracket 3 and move together with the upper rail 52, or it can be mounted on the motorcycle body 1, depending on the actual design. The first motor 53 is connected to the first drive shaft 54 on both sides and extends from the first drive shaft 54 to the upper rail 52 to engage with it for transmission. The transmission structure between the first drive shaft 54 and the upper rail 52 can adopt, for example, a rack and pinion transmission structure. A gear is installed at the first drive shaft 54, and a rack is installed at the upper rail 52. The first motor 53 drives the first drive shaft 54 to rotate forward or backward, thereby driving the first drive shaft 54 to rotate forward or backward, which in turn drives the gear to rotate forward or backward, causing the meshing rack to move forward or backward, thus moving the upper rail 52 forward or backward and adjusting the fore-and-aft position of the backrest 4. The overall structure of the rear bracket 3 can cover other components behind it, achieving both aesthetic appeal and structural protection.
[0017] As an improved specific implementation, the rotating mechanism 6 includes a fixed frame 61, a rotating frame 62, a second motor 63, and a second drive shaft 64. The fixed frame 61 consists of two sets and is installed on both sides of the rear support 3. The rotating frames 62 are installed on both sides of the backrest 4. The rotating frames 62 are rotatably mounted on the fixed frames 61 on both sides. The second motor 63 is located on one side of the fixed frame 61. The second drive shaft 64 extends from the second motor 63 to the rotating frames 62 on both sides, and the second drive shaft 64 and the rotating frames 62 are driven by a transmission structure.
[0018] like Figure 2 As shown, the fixed frame 61 is mounted on the upper rail 52. A hole-shaft structure can be used between the rotating frame 62 and the fixed frame 61 to allow relative rotation. The second motor 63 is housed on the outside of one side of the fixed frame 61 and extends to the other side via a second drive shaft 64. The two sides of the second drive shaft 64 engage with the two sides of the rotating frame 62 for transmission. The transmission structure between the second drive shaft 64 and the rotating frame 62 can employ, for example, a multi-gear meshing transmission structure. A gear is installed at the second drive shaft 64, and an internal ring gear is installed at the rotating frame 62. The gears mesh with the internal ring gear for further transmission. The second motor 63 drives the second drive shaft 64 to rotate forward or backward, which in turn drives the gear set to rotate forward or backward, causing the rotating frame 62 to rotate forward or backward, thereby adjusting the front-to-back angle of the backrest 4. The overall structure of the rear support 3 can cover the second motor 63, the fixed frame 61, and other components, achieving both aesthetic appeal and structural protection. The lower structure of the backrest 4 can cover the second drive shaft 64, achieving both aesthetic appeal and structural protection.
[0019] As an improved specific implementation, the motorcycle body 1 is provided with mounting brackets 11 on both sides, and the lower rail 51 extends downward to provide a mounting plate 55. The mounting plate 55 and the mounting brackets 11 are provided with a number of corresponding mounting holes and are installed and fixed by fasteners 56.
[0020] like Figure 2 As shown, the mounting brackets 11 on both sides extend from front to back, forming a structural reinforcement at the bottom; the mounting plate 55 extends downward and has mounting holes at the bottom for alignment with the mounting holes on the mounting brackets 11. Then, the structure is locked in multiple positions by fasteners 56, which can stably arrange the rear bracket 3 and the backrest 4.
[0021] As an improved specific implementation, an installation platform is formed on the upper surface of the rear bracket 3.
[0022] like Figure 1 As shown, the installation platform can be used to install cargo boxes, thereby expanding the storage capacity of motorcycles.
[0023] The above are merely preferred embodiments of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are within its protection scope. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within its protection scope.
