When a first feature is "below," "below," or "below" a second feature, it may mean that the first feature is directly below or diagonally below the second feature, or simply means that the first feature is at a lower level than the second feature.

[0058] like Figure 1-14 As shown, the utility model provides a motorcycle seat, comprising a seat body 100, a back cushion 200 and a locking assembly.

[0059] The back cushion 200 is disposed at the rear end of the seat body 100 , and the front end of the back cushion 200 is hinged to the seat body 100 so that the second end of the back cushion 200 can rotate relative to the seat body 100 .

[0060] Specifically, if Figure 1 、 6 As shown in Figure 11, a first connecting element 500 is fixedly provided on the top of the seat body 100. The first connecting element 500 is U-shaped. A first hinge shaft 700 is provided in the middle of the first connecting element 500. The first hinge shaft 700 is connected to both sides of the first connecting element 500. A second connecting element 600 is fixedly connected to the front end of the cushion 200. The second connecting element 600 is hinged to the first connecting element 500 through the first hinge shaft 700.

[0061] The locking assembly is provided on the back cushion 200 and the seat body 100 and is used to lock the back cushion 200 so that the back cushion 200 cannot rotate (ie cannot rotate in the forward direction or in the reverse direction) or cannot rotate in the reverse direction.

[0062] It should be noted that the positive direction mentioned in the present invention refers to the direction in which the cushion 200 moves from the initial position to the working position, and the reverse direction is the direction opposite to the positive direction, that is, the direction in which the cushion 200 moves from the working position to the initial position.

[0063] When in use, the cushion 200 is rotated to the target position. Under the action of the locking component, the cushion 200 cannot be rotated toward the initial position, so that the user can lean on the cushion 200, thereby achieving the purpose of providing the user with a place to lean on, and further achieving the purpose of providing the user with a more comfortable resting environment.

[0064] The motorcycle seat provided by the present invention can provide a more comfortable resting environment for the user. At the same time, when in use, the user only needs to manually rotate the cushion 200 to the target position and then use the locking assembly to lock the cushion 200. It is easy to operate, does not require an additional power device, has low cost, and saves resources.

[0065] like Figure 1-14 As shown, the locking assembly includes a locking disk 310 and a locking element 320 .

[0066] The locking plate 310 is coaxially arranged at the hinge center of the cushion 200 and the seat body 100. The locking plate 310 is rotationally connected to the seat body 100 and fixedly connected to the cushion 200. The outer peripheral wall of the locking plate 310 is provided with a first locking portion.

[0067] Specifically, the locking plate 310 is coaxially sleeved on the first hinge shaft 700 and is rotationally connected to the seat body 100 through the first hinge shaft 700. The locking plate 310 is fixedly connected to the second connecting element 600.

[0068] The locking element 320 is correspondingly provided with a second locking portion adapted to the first locking portion. The locking element 320 has a locking position and an unlocking position. The locking element 320 is movably connected to the seat body 100 so that the locking element 320 can reciprocate between the locking position and the unlocking position.

[0069] Among them, when the locking element 320 is in the locked position, the second locking part and the first locking part cooperate so that the cushion 200 can only rotate in the positive direction or cannot rotate; when the locking element 320 is in the unlocked position, the second locking part and the first locking part are separated so that the cushion 200 can rotate in both the positive direction and the reverse direction.

[0070] like Figure 4 、 9 As shown in Figures 12, 13, and 14, the locking assembly also includes an elastic element 330.

[0071] Both ends of the elastic element 330 are connected to the locking element 320 and the seat body 100 respectively. In a natural state, the elastic element 330 applies elastic force to the locking element 320 so that the locking element 320 tends to move from the unlocked position to the locked position.

[0072] During use, when the locking element 320 is placed in the locked position, under the action of the elastic force of the elastic element 330, the locking element 320 can only move from the locked position to the unlocked position when overcoming the elastic force of the elastic element 330, so as to achieve the purpose of keeping the locking assembly in the locked state.

[0073] like Figure 3 、 4 As shown in Figures 5, 8, 9 and 10, the first locking portion is a first one-way tooth structure 311 provided on the outer peripheral wall of the locking disk 310, and the second locking portion is a second one-way tooth structure 321 that cooperates with the first one-way tooth structure 311.

[0074] When the locking element 320 is in the locking position, the second one-way tooth structure 321 cooperates with the first one-way tooth structure 311 to prevent the cushion 200 from rotating in the reverse direction.

[0075] When the locking element 320 is in the unlocking position, the second one-way tooth structure 321 is separated from the first one-way tooth structure 311 , so that the cushion 200 can rotate in both the forward direction and the reverse direction.

[0076] Specifically, in the working state, under the action of the elastic force of the elastic element 330, the locking element 320 tends to move from the unlocked position to the locked position. When the cushion 200 is rotated in the positive direction, the cushion 200 rotates in the positive direction with the locking disk 310. Under the interaction of the guiding inclined surfaces of the first one-way tooth structure 311 and the second one-way tooth structure 321, the locking element 320 overcomes the elastic force of the elastic element 330 and moves from the locked position to the unlocked position, thereby achieving the purpose of enabling the cushion 200 to rotate in the positive direction.

[0077] When the back cushion 200 is rotated in the reverse direction, the back cushion 200 rotates with the locking plate 310 in the reverse direction. Under the interaction of the stop surfaces of the first one-way tooth structure 311 and the second one-way tooth structure 321, the locking plate 310 cannot be rotated in the reverse direction, and thus the back cushion 200 cannot be rotated in the reverse direction.

[0078] When the cushion 200 needs to be rotated from the working position to the initial position, the locking element 320 is placed in the unlocking position, so that the first one-way tooth structure 311 and the second one-way tooth structure 321 are separated, thereby allowing the cushion 200 to rotate in the opposite direction.

[0079] The locking assembly of this structure has a simple structure, a reasonable design, and is easy to operate.

[0080] like Figure 3 、 4As shown in Figures 5, 8, 9 and 10, in this embodiment, the locking element 320 is hinged to the first connecting element 500 through the second hinge shaft 800, and the elastic element 330 is a torsion spring.

[0081] Optionally, the motorcycle seat provided by the present invention further includes an unlocking assembly, which is provided on the seat body 100 and the back cushion 200 .

[0082] In the working state, when the rotation angle of the cushion 200 exceeds a preset angle, the unlocking component places the locking element 320 in the unlocked position and maintains the locking element 320 in the unlocked position so that the cushion 200 can rotate in the opposite direction; when the cushion 200 rotates to the initial position, the unlocking component releases the restriction on the locking element 320 so that the locking element 320 can move back and forth between the unlocked position and the locked position.

[0083] Specifically, during use, when the angle of rotation of the cushion 200 exceeds a preset angle, the unlocking assembly places the locking element 320 in the unlocked position and maintains the locking element 320 in the unlocked position to separate the first locking part from the second locking part, thereby allowing the cushion 200 to rotate in both the forward direction and the reverse direction.

[0084] When the backrest 200 rotates to the initial position, the unlocking assembly releases the restriction on the locking element 320 so that the locking element 320 can reciprocate between the unlocking position and the locking position.

[0085] like Figure 2 、 3 As shown in Figures 4, 5, 7, 8, 9, and 10, the unlocking component includes an unlocking disk 410 and a switching structure.

[0086] The unlocking plate 410 is coaxially disposed at the hinge center of the back cushion 200 and the seat body 100. The unlocking plate 410 is rotatably connected to the seat body 100. The outer peripheral wall of the unlocking plate 410 is provided with an unlocking portion 411. The distance between the side wall of the unlocking portion 411 and the axis of the locking plate 310 is greater than or equal to the radius of the locking plate 310. When the unlocking portion 411 corresponds to the locking element 320, the locking element 320 can be maintained in the unlocked position by the unlocking portion 411.

[0087] like Figure 2 、 3 As shown in Figures 4, 5, 7, 8, 9 and 10, the unlocking disk 410 is sleeved on the first hinge shaft 700 and is rotatably connected to the first hinge shaft 700.

[0088] The switching structure is provided on the back cushion 200 and the unlocking disk 410 .

[0089] When the rotation angle of the cushion 200 exceeds a preset angle, the cushion 200 places the unlocking disk 410 in the first position through the switching structure so that the unlocking portion 411 corresponds to the locking element 320, thereby driving the locking element 320 to the unlocked position and maintaining it in the unlocked position.

[0090] When the cushion 200 rotates to the initial position, the cushion 200 places the unlocking disk 410 in the second position through the switching structure to separate the unlocking portion 411 from the locking element 320, thereby allowing the locking element 320 to reciprocate between the unlocking position and the locking position.

[0091] Preferably, the unlocking portion 411 is arc-shaped.

[0092] The unlocking component of this structure has a simple structure and a reasonable design. By rotating the cushion 100 and making the rotation angle of the cushion 100 exceed the preset value, the locking element 320 can be placed in the unlocked position. By rotating the cushion 100 back to the initial position, the locking element 320 can be placed in the locked position. The operation is convenient.

[0093] like Figure 2 、 3 As shown in , 4 and 5 , the switching structure includes a first toggle element 421 .

[0094] The first toggle element 421 is fixedly connected to the cushion 200. Specifically, Figure 4 、 5 As shown, the first shifting element 421 is fixedly connected to the second connecting element 600. The unlocking disk 410 is correspondingly provided with a first blocking wall 422 and a second blocking wall 423 that cooperate with the first shifting element 421.

[0095] Among them, in the working state, when the rotation angle of the cushion 200 exceeds a preset value, the cushion 200 applies a force to the first blocking wall 422 through the first toggle element 421, thereby driving the unlocking disk 410 to rotate to the first position, so that the unlocking portion 411 corresponds to the locking element 320, thereby achieving the purpose of keeping the locking element 320 in the unlocked position; when the cushion 200 rotates to the initial position, the cushion 200 applies a force to the second blocking wall 423 through the first toggle element 421, thereby driving the unlocking disk 410 to rotate to the second position, so that the unlocking portion 411 is separated from the locking element 320, thereby achieving the purpose of enabling the locking element 320 to move between the unlocked position and the locked position.

[0096] The switching structure of this structure has the advantages of simple structure, reasonable design and convenient operation.

[0097] like Figure 7 、 8As shown in , 9 and 10 , the switching structure includes a second toggle element 431 .

[0098] The second toggle element 431 is fixedly connected to the cushion 200. Specifically, Figure 9 、 10 As shown, the second shifting element 431 is fixedly connected to the second connecting element 600 .

[0099] The unlocking disk 410 is correspondingly provided with a third blocking wall 432 that cooperates with the second toggle element 431 . The locking disk 310 is provided with a driving portion 433 . The unlocking disk 410 can move from the second position to the first position under the action of gravity.

[0100] Among them, in the working state, when the rotation angle of the cushion 200 exceeds a preset value, the cushion 200 drives the locking element 320 to the unlocked position through the driving part 433, and the unlocking disk 410 moves from the second position to the first position under the action of gravity, so that the unlocking part 411 corresponds to the locking element 320, thereby achieving the purpose of keeping the locking element 320 in the unlocked position; when the cushion 200 is rotated to the initial position, the cushion 200 applies a force to the third blocking wall 432 through the second toggle element 431 to drive the unlocking disk 410 to rotate to the second position, so that the unlocking part 411 is separated from the locking element 320, thereby achieving the purpose of enabling the locking element 320 to move between the unlocked position and the locked position.

[0101] The switching structure of this structure has the advantages of simple structure, reasonable design and convenient operation.

[0102] like Figure 11-14 As shown, the first locking portion is a plurality of locking holes 312 opened on the locking disk 310 and extending along the axial direction of the locking disk 310. The plurality of locking holes 312 are arranged in sequence at intervals around the axial direction of the locking disk 310, and the second locking portion is a locking pin 322 adapted to the locking hole.

[0103] When the locking element 320 is in the locking position, the locking pin 322 cooperates with the locking socket 312 to prevent the back cushion 200 from rotating, thereby achieving the purpose of keeping the back cushion 200 at the target position.

[0104] When the locking element 320 is in the unlocked position, the locking pin 322 and the locking socket 312 are separated, so that the backrest 200 can be rotated in both the forward and reverse directions.

[0105] like Figure 11-14 As shown, the locking element 320 is provided with an operating portion 900 to facilitate moving the locking element 320 .

[0106] like Figure 13-14As shown, the elastic element 330 is a spring.

[0107] like Figure 1 、 6 As shown in Figures 11, the front end of the back cushion 200 is hinged to the middle part of the seat body 100 so that when the back cushion 200 is in the working position, the rear end of the seat body 100 can still carry people. When the back cushion 200 is in the initial position, the back cushion 200 is located above the rear end of the seat body 100 and is supported by the rear end of the seat body 100, so that people can still be carried above the back cushion 200.

[0108] In the specification of the present invention, a large number of specific details are described. However, it is understood that the embodiments of the present invention can be practiced without these specific details. In some instances, well-known methods, structures and techniques are not shown in detail so as not to obscure the understanding of this specification.

[0109] Finally, it should be noted that 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 above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or make equivalent replacements for some or all of the technical features therein.
