[0036] Referring to Figure 1 、 Figures 4-5 In one embodiment, the frame 70 comprises a front pipe 71, a load-bearing frame 72, a loading frame 73 and a reinforcing beam 75. The front pipe 71 is provided for the front fork of the motorcycle 100 to pass through and allows the front fork to rotate in the front pipe 71. The load-bearing frame 72 and the loading frame 73 are both configured in two groups. The two groups of load-bearing frames 72 and loading frames 73 are connected to the front pipe 71 and form an enclosure. The load-bearing frame 72 comprises an upper beam 721 and a rear beam 722. The loading frame 73 comprises a bottom beam 731 and a lower beam 732. The two ends of the upper beam 721 are respectively connected to the front pipe 71 and the top end of the rear beam 722. The bottom beam 731 and the lower beam 732 are located on the side of the upper beam 721 relatively close to the ground. The bottom end of the rear beam 722 is connected to the lower end of the bottom beam 731. The two ends of the lower beam 732 are respectively connected to the front pipe 71 and the front end of the bottom beam 731. The top end and the bottom end of the rear beam 722 are respectively the end of the rear beam 722 relatively far from the ground and the end relatively close to the ground. The two bottom beams 731 form the bottom side of the frame 70 closest to the ground. The cushion support 10 is located on the side of the load-bearing frame 72 relatively far from the loading frame 73. The power battery 80 is placed in the enclosure. The two ends of the reinforcing beam 75 are respectively fixedly connected to the two lower beams 732 and used for supporting the power battery 80. The space between the two upper beams 721 forms a battery passage for the power battery 80 to pass through so as to move in or out of the enclosure.

[0037] Further, referring to Figures 4-5 , the frame 70 further comprises a load seat 74 fixed to the load carrier 72, the load seat 74 comprises a plurality of sets of mounting portions, each set of mounting portions defines an installation position as a whole, and forms a detachable fixed connection with the cushion support platform 10, the height of the plurality of installation positions from the ground changes in a decreasing trend along the extension direction of the load carrier 72, the extension direction of the load carrier 72 includes the extension direction of the upper beam 721, the upper beam 721 extends away from the front pipe 71 and gradually approaches the ground and the bottom beam 731. When the cushion support platform 10 is connected with any set of mounting portions, the position of the cushion support platform 10 is the installation position of this set of mounting portions. Therefore, the frame 70 provides a plurality of installation positions corresponding to different sitting heights by setting a plurality of sets of mounting portions, so that the frame 70 can provide a plurality of sitting heights, and by switching the mounting portion connected with the cushion support platform 10, the cushion support platform 10 can be transferred from the installation position defined by the disassembled mounting portion to a new installation position, and the height of the cushion on the cushion support platform 10 changes accordingly.

[0038] Further, referring to Figures 1-2 , the top of the power battery 80 is provided with a battery handle 81 for the user to hold, the top of the power battery 80 is the end of the power battery 80 relatively far away from the reinforcing beam 75 and relatively close to the battery passageway, the battery handle 81 comprises a holding rod, and the extension direction of the holding rod is the same as the extension direction of the upper beam 721. The battery handle 81 not only can be held by the user to exert a lifting force to take out the power battery 80 from the cage, but also can be used to jointly lift and support the quick disassembly and assembly cushion unit with the frame 70. Specifically, the cushion support platform 10 comprises a cushion support 11, each set of mounting portions is detachably connected with the cushion support 11, and the frame 70 supports the cushion support 11 through the load carrier 72 and the load seat 74; the detachable cushion 20 comprises a front mounting portion 21 and a rear mounting portion 22, the front mounting portion 21 is detachably connected with the battery handle 81, the rear mounting portion 22 is detachably connected with the cushion support 11, and the power battery 80 supports the front mounting portion 21 through the battery handle 81. In this way, the quick disassembly and assembly cushion unit not only exerts a force on the load carrier 72 through the cushion support 11, but also exerts a force on the loading carrier 73 through the power battery 80, so that the pressure of the quick disassembly and assembly cushion unit on the frame 70 is dispersed to different positions, thereby improving the stress condition of the frame 70 and avoiding local concentrated stress on the frame 70.

[0039] Further, referring to Figures 1-2The quick detachable seat cushion unit further comprises a quick detachable positioning member 25 arranged on the front mounting portion 21, and the quick detachable positioning member 25 is detachably connected with the battery handle 81. When the quick detachable positioning member 25 is connected with the battery handle 81, the freedom of the front mounting portion 21 from the battery handle 81 is limited by the quick detachable positioning member 25, so that the connection between the front mounting portion 21 and the battery handle 81 is stable and not easy to be separated. When the quick detachable seat cushion unit needs to be detached, the quick detachable positioning member 25 needs to be separated from the battery handle 81 to release the freedom of the front mounting portion 21 from the battery handle 81. Optionally, the quick detachable positioning member 25 is detachably connected with the front mounting portion 21. Referring to Figures 2-4 In some embodiments, the front mounting portion 21 and the handle rod of the battery handle 81 form a sliding fit along the extension direction of the upper beam 721, and the extension direction of the upper beam 721 is the extension direction of the handle rod. The front mounting portion 21 is provided with a plurality of positioning holes 26 for the quick detachable positioning member 25 to pass through, and the plurality of positioning holes 26 are arranged along the extension direction of the handle rod. In this way, the connection between the front mounting portion 21, the quick detachable positioning member 25 and the battery handle 81 can adapt to the height adjustment of the sitting posture, and the sliding fit between the front mounting portion 21 and the battery handle 81 can adapt to the switching of the seat cushion platform 10 between different mounting positions.

[0040] Optionally, the battery handle 81 is provided with a positioning member counterbore, and the quick detachable positioning member 25 can further extend into the positioning member counterbore after passing through the positioning hole 26, so as to form a detachable connection with the battery handle 81. In this way, the quick detachable positioning member 25 and the battery handle 81 are easier to detach. Referring to Figures 1-3 In some embodiments, the detachable seat cushion 20 further comprises a cover plate portion 23 for supporting the hips of a user. The cover plate portion 23 is arranged above the front mounting portion 21 and above the rear mounting portion 22, and covers the quick detachable positioning member 25 passing through the positioning hole 26. The cover plate portion 23 and the front mounting portion 21 can form a detachable connection. When it is necessary to release the locking state between the front mounting portion 21 and the battery handle 81, the cover plate portion 23 and the front mounting portion 21 are first detached to make the cover plate portion 23 be lifted, so that the quick detachable positioning member 25 is exposed, and then the quick detachable positioning member 25 is sequentially withdrawn from the positioning member counterbore and the positioning hole 26. In the daily driving process, the cover plate portion 23 remains arranged on the front mounting portion 21. As shown in Figure 4 The front mounting portion 21 and the rear mounting portion 22 of the detachable seat cushion 20 are respectively supported and elevated by the battery handle 81 and the seat cushion support 11, and the cover plate portion 23 is removed. When the detachable seat cushion 20 is detached from the seat cushion platform 10, the cover plate portion 23, the front mounting portion 21 and the rear mounting portion 22 are detached as a whole and moved away. The edges of the front mounting portion 21 and the rear mounting portion 22 are matched with the edge of the cover plate portion 23, so as to limit the cover plate portion 23 from being offset and swung relative to the front mounting portion 21 and the rear mounting portion 22.

[0041] The detachable cushion unit of the utility model further includes a cushion lock 30, a pulling piece 40 and a lock body 50, the cushion lock 30 is movably arranged in one of the cushion support platform 10 and the detachable cushion 20, and can shift between a preset locking position and a preset unlocking position, the pulling piece 40 is connected with the cushion lock 30, and is used for being pulled by a user to drive the cushion lock 30 to shift from the locking position to the unlocking position, and the lock body 50 is arranged in the other one of the cushion support platform 10 and the detachable cushion 20. In the locking position, the cushion lock 30 locks and fixes the lock body 50, and restricts the detachable cushion 20 from being detached from the cushion support platform 10, and in the unlocking position, the cushion lock 30 unlocks the lock body 50, and allows the detachable cushion 20 to be detached from the cushion support platform 10. The locking position and the unlocking position are two positions passed through by the cushion lock 30 when the cushion lock 30 is moved relative to the cushion support platform 10 or the detachable cushion 20. The detachable cushion unit of the utility model will be described in detail below by taking the embodiment that the cushion lock 30 is movably arranged in the cushion support platform 10 and the lock body 50 is arranged in the detachable cushion 20 as an example.

[0042] In some embodiments, the cushion support platform 10 further includes a guide part 12 fixedly arranged relative to the cushion support 11, and the detachable cushion 20 further includes an adapting part 24 arranged in the rear arranging part 22, and the guide part 12 and the adapting part 24 can be slidably matched along the length direction of the rear arranging part 22. In the state that the cushion lock 30 shifts to the unlocking position and unlocks the lock body 50, the adapting part 24 can move upwardly and rearwardly or move downwardly and forwardly along the guide part 12. The length direction of the rear arranging part 22 is configured such that when the adapting part 24 moves upwardly and rearwardly along the length direction of the rear arranging part 22, the contact area between the guide part 12 and the adapting part 24 decreases, the detachable cushion 20 can gradually move away from the front pipe 71 and gradually move away from the ground, and the detachable cushion 20 tends to be detached from the cushion support platform 10; and when the adapting part 24 moves downwardly and forwardly along the length direction of the rear arranging part 22, the contact area between the guide part 12 and the adapting part 24 increases, the detachable cushion 20 can gradually move close to the front pipe 71 and gradually move close to the ground, and the detachable cushion 20 tends to be installed in place with the cushion support platform 10.

[0043] It should be noted that after the guide part 12 cooperates with the adapting part 24, the guide part 12 is located on the side of the adapting part 24 that is relatively far away from the ground, and therefore the freedom of the adapting part 24 to move upwardly and away from the ground is limited by the guide part 12. In this way, the detachable cushion 20 cannot move away from the ground to be detached from the cushion support platform 10, and therefore the installation of the detachable cushion 20 can be ensured to be reliable and the detachable cushion 20 can be prevented from being accidentally detached from the cushion support platform 10. Specifically, the detachable activity of the detachable cushion 20 relative to the cushion support platform 10 includes the adapting part 24 moving upwardly and rearwardly along the length direction of the rear arranging part 22. Referring to Figures 2-3 、 Figures 5-6The seat support 11 includes a guide frame 14, and a seat lock 30 is slidably disposed on the guide frame 14. The guide frame 14 extends along the length direction of the rear placement portion 22 and limits the seat lock 30 to slide along the length direction of the rear placement portion 22 when it is moved.

[0044] With this configuration, the user can stand behind the motorcycle 100 and pull the pull-out member 40 along the length of the rear mounting portion 22, causing the seat lock 30 to slide from the locked position to the unlocked position along the length of the rear mounting portion 22 and unlocking the lock body 50. The user can then continue to pull the removable seat 20 backward and upward along the length of the rear mounting portion 22 from its original position. When unlocking and removing the removable seat 20, the user does not need to change their standing position, and the two backward pulling actions maintain the same direction of force, allowing for quick completion without the need for external tools. When unlocking and removing the removable seat 20, the user can apply minimal pulling force along the length of the rear mounting portion 22. Therefore, the length of the rear mounting portion 22 serves as a preset sliding direction. In some embodiments, both the seat lock 30 and the removable seat 20 slide relative to the seat support 10 along this preset sliding direction.

[0045] Optionally, a guide groove is formed between the side of the guide portion 12 closest to the ground and the seat cushion support 11. The guide groove extends along the length of the rear mounting portion 22 to allow the adapter portion 24 to slide inside. The opening of the guide groove opens toward the rear end of the removable seat cushion 20, so that the adapter portion 24 can move backward and upward along the length of the rear mounting portion 22 and exit the guide groove. When the adapter portion 24 is located in the guide groove, the removable seat cushion 20 and the seat cushion support 10 are in the installed position. At this time, the position of the removable seat cushion 20 just meets the requirements of the user sitting on the removable seat cushion 20. The guide portion 12 and the seat cushion support 11 together clamp and fix the adapter portion 24. This design further restricts the degree of freedom of the removable seat cushion 20 to deflect and move relative to the seat cushion support 10. When the seat cushion lock 30 unlocks the lock body 50, the removable seat cushion 20 can only slide precisely along the length direction of the rear placement part 22, thereby ensuring that when the user pulls out the removable seat cushion 20, the front end of the removable seat cushion 20 is always supported and lifted by the seat cushion support 10 and will not fall off.

[0046] The removable seat cushion 20 and the seat cushion support 10 are located at Figure 2 When the installation is in place as shown, the adapter 24 is inserted to the maximum depth in the guide limiting groove. At this time, if the pulling force acting on the pull-out member 40 is removed and the seat lock 30 is moved to the locking position, the seat lock 30 abuts against and stops the lock body 50, and at the same time restricts the removable seat 20 from moving backward and upward along the length direction of the rear placement part 22. This prevents the adapter 24 from exiting the guide limiting groove and ensures that the adapter 24 is reliably clamped and fixed by the guide part 12 and the seat support 11.

[0047] In some embodiments, the cushion lock 30 is hookingly connected with the lock body 50 in the locked position, and is mutually disengaged and unhooked with the lock body 50 in the unlocked position. Specifically, referring to Figure 3 and Figure 6 , the cushion lock 30 is a movable hook plate 31 slidingly arranged in the guide frame 14, the movable hook plate 31 is provided with a through hole 32 and a guide hole 33, the lock body 50 includes a pin portion 51 and an anti-extraction portion 52, both ends of the pin portion 51 are respectively connected with the bottom of the detachable cushion 20 and the anti-extraction portion 52, the detachable cushion 20 and the movable hook plate 31 are respectively located on the opposite sides of the guide frame 14, the guide frame 14 includes a guide column 141 extending into the guide hole 33, the opening shape of the guide hole 33 is strip-shaped and extends along the length direction of the rear seating portion 22, the inner wall of the guide hole 33 is slidingly matched with the guide column 141, so that the movable hook plate 31 slides along the length direction of the rear seating portion 22 to shift between the locked position and the unlocked position; the pin portion 51 extends into the through hole 32 from the side of the movable hook plate 31 close to the detachable cushion 20, and the anti-extraction portion 52 extends out of the through hole 32 from the side of the movable hook plate 31 away from the detachable cushion 20. When the movable hook plate 31 locks the lock body 50, the pin portion 51 abuts against the inner wall of the through hole 32, and the anti-extraction portion 52 abuts against the side of the movable hook plate 31 away from the detachable cushion 20 to limit the pin portion 51 from exiting the through hole 32.

[0048] The shape of the through hole 32 is not limited, as long as the opening size of the through hole 32 meets the following requirements: when the movable hook plate 31 is pulled to the unlocked position by the puller 40, the lock body 50 can exit or re-enter the through hole 32 along the axial direction of the pin portion 51. As shown in Figure 3 and Figure 6 , in some embodiments, the opening shape of the through hole 32 is strip-shaped and extends along the length direction of the rear seating portion 22. It can be understood that in other embodiments, the opening shape of the through hole 32 can also be oval, polygonal or other irregular shapes. After the cushion lock 30 is driven by the puller 40 and shifted to the unlocked position, the user can apply a lifting force to the detachable cushion 20 to make the rear seating portion 22 of the detachable cushion 20 slightly deform upward, the lifting force includes a vector acting along the axial line of the pin portion 51, so that the lock body 50 can be driven to exit the through hole 32 along the axial direction of the pin portion 51, and then the user can pull the detachable cushion 20 upward and backward along the preset sliding direction to make the fitting portion 24 exit the guide limiting slot. Therefore, the disassembly movement of the detachable cushion 20 relative to the cushion support 10 also includes the exit of the lock body 50 from the through hole 32 along the axial line of the pin portion 51 and the upward deformation of the rear seating portion 22. The axial direction of the pin portion 51 is perpendicular to the length direction of the rear seating portion 22, or they can also form other angles.

[0049] Further, in some embodiments, the quick detachable cushion unit further comprises a reset member 60 for driving the cushion lock 30 to shift from the unlocking position to the locking position, the reset member 60 comprising an acting end 61, an elastic section 63 and a mounting end 62, the acting end 61 and the mounting end 62 being connected to two ends of the elastic section 63 respectively, the acting end 61 being connected to the cushion lock 30, the mounting end 62 being connected to one of the cushion support 10 and the detachable cushion 20, the elastic section 63 being capable of elastically deforming to drive the acting end 61 to move relative to the mounting end 62, thereby achieving the driving effect on the cushion lock 30. Referring to Figures 5-6 , the elastic section 63 is a cylindrical spring section, the cylindrical spring section being in a stretched state, the acting end 61 being hooked to the movable hook plate 31, the mounting end 62 being hooked to the cushion support 11, the axial direction of the elastic section 63 being the same as the aforementioned preset sliding direction, the elastic section 63 having a potential energy of contraction deformation to drive the acting end 61 to move close to the mounting end 62, thus the movable hook plate 31 has a tendency to move along the axial direction of the elastic section 63 towards the front tube 71 and the ground under the pulling force of the acting end 61.

[0050] Specifically, when the user pulls the pulling member 40, the pulling force of the pulling member 40 acting on the movable hook plate 31 is sufficient to offset the contraction deformation of the elastic section 63, thereby the tendency of the movable hook plate 31 to move along the axial direction of the elastic section 63 away from the front tube 71 and the ground can be overcome, so as to make the movable hook plate 31 move away from the locking position and shift to the unlocking position; after the user cancels the pulling force acting on the pulling member 40, the potential energy of the contraction deformation of the elastic section 63 makes the acting end 61 move along the axial direction of the elastic section 63 close to the mounting end 62, while driving the movable hook plate 31 to move along the axial direction of the elastic section 63 close to the front tube 71 and the ground, thereby making the movable hook plate 31 move away from the unlocking position and shift to the locking position. Since the reset member 60 always keeps the pulling force acting on the movable hook plate 31, the movable hook plate 31 can be kept in the locking position for a long time, the pin portion 51 always abuts against the inner wall of the through hole 32 and the anti-disengagement portion 52 always abuts against the side of the movable hook plate 31 facing away from the detachable cushion 20. It can be understood that in other embodiments, the reset member 60 can also be cancelled, or the type of the reset member 60 is not limited to the elastic element shown in the drawings, but can also use a push rod, a motor or the like as the reset member 60. Figures 5-6

[0051] Further, referring to Figure 6 ​The pulling member 40 comprises a pulling rope 41 and a rope end fastener 42, the rope end fastener 42 fixes one end of the pulling rope 41 to the movable hook plate 31. A user can apply pulling force to the pulling rope 41 to drive the movable hook plate 31 to slide from the locking position to the unlocking position. The pulling rope 41 extends from between the cushion support 11 and the rear mounting portion 22, and extends out of the tail end of the detachable cushion 20, the tail end of the detachable cushion 20 comprises the end of the rear mounting portion 22 opposite to the front mounting portion 21, and the front end of the detachable cushion 20 comprises the end of the front mounting portion 21 opposite to the rear mounting portion 22. In this way, when a user pulls the pulling rope 41 rearward and upward to move the cushion lock 30 to the unlocking position, the user can also pull the pulling rope 41 upward slightly, the pulling rope 41 abuts against the rear mounting portion 22 and drives the rear mounting portion 22 to deform slightly upward, the deformed rear mounting portion 22 forms a gap with the cushion support 10, which allows the user to put fingers into the gap to hold the detachable cushion 20.

[0052] Further, referring to Figure 3 The anti-disengagement portion 52 comprises a limiting side 521 and a sliding side 522, the limiting side 521 protrudes from the outer circumferential wall of the pin portion 51 to abut against the side of the cushion lock 30 opposite to the detachable cushion 20, and the distance of the sliding side 522 from the axis of the pin portion 51 decreases in the direction away from the limiting side 521. As preferred, the anti-disengagement portion 52 is conical or circular-tapered and is fixed to the end of the pin portion 51 opposite to the detachable cushion 20, the bottom of the cone or the circular taper forms the limiting side 521, and the outer circumferential wall of the cone or the circular taper forms the sliding side 522. When a user prepares to reinstall the detachable cushion 20 to the cushion support 10, the user first slightly bends the rear mounting portion 22 to deform the rear mounting portion 22 to facilitate the alignment of the fitting portion 24 with the opening of the guide limiting slot, and then presses and hits the detachable cushion 20, specifically, the user can press and hit the portion of the cover plate portion 23 covering the rear mounting portion 22, since this portion of the cover plate portion 23 and the rear mounting portion 22 are inclined with respect to the horizontal direction and the vertical direction, the pressure when the user presses and hits the detachable cushion 20 can provide a forward pushing vector, the forward pushing vector drives the fitting portion 24 to move forward and downward along the preset sliding direction and to be inserted into the guide limiting slot, and the pressing and hitting of the detachable cushion 20 by the user can drive the anti-disengagement portion 52 to slide against the opening edge of the through hole 32 through the sliding side 522, thus the lock body 50 drives the movable hook plate 31 to move to the unlocking position through the anti-disengagement portion 52, and the position of the through hole 32 changes accordingly, when the pin portion 51 is arranged in the through hole 32 and the sliding side 522 is away from the opening edge of the through hole 32, the force of the reset member 60 acting on the movable hook plate 31 drives the movable hook plate 31 to return to the locking position.

[0053] Thus, the user is more convenient and fast when reinstalling the detachable cushion 20 to the cushion support 10, and the operation is simple and convenient. When reinstalling the detachable cushion 20, the puller 40 does not need to be pulled to drive the cushion lock 30 to move to the unlocking position. Even if the cushion lock 30 is in the locking position, the lock body 50 can automatically drive the cushion lock 30 to move to the unlocking position to make the pin part 51 penetrate into the through hole 32 by tapping the detachable cushion 20, and the operation can be completed by hand without the aid of tools. After the sliding contact side 522 leaves the opening edge of the through hole 32, the reset part 60 drives the movable hook plate 31 to reset until the inner wall of the through hole 32 abuts against the pin part 51. The user only needs to listen to the impact sound of the inner wall of the through hole 32 abutting against the pin part 51 to confirm that the detachable cushion 20 is reinstalled in place.

[0054] As shown in Figure 3 and Figure 6 When the cushion lock 30 in the locking position is connected with the lock body 50, the lock body 50 abuts against the movable hook plate 31 on the side away from the detachable cushion 20 through the limiting side 521, and the movable hook plate 31 abuts against the pin part 51 of the lock body 50 through the inner wall of the through hole 32.

[0055] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description simple, all possible combinations of the technical features in the above-mentioned embodiments are not described, but as long as the combinations of the technical features do not exist contradictory, they should be considered as the scope of the present disclosure.
