Description

Technical Field

[0001] The utility model relates to the technical field of motorcycles, and particularly relates to a motorcycle seat, a battery cover assembly and a motorcycle. Background Art

[0002] With the development of motorcycles, motorcycles have changed from traditional fuel motorcycles to electric motorcycles. After the change of motorcycle types, in order to reduce the modification of motorcycles, it has become very common to change the original fuel tank position of fuel motorcycles to the battery position. For example, a battery fixing assembly and an electric motorcycle battery accommodating structure with a patent publication number of CN219447216U and an application date of April 2023. In this patent, the battery is fixed from above by a battery fixing assembly connected to the frame. Before the battery is taken out, the lock of the vehicle cover needs to be opened first, so that after the vehicle cover rotates and opens, the battery compartment can be exposed, facilitating the loosening of the upper pressing of the battery by the battery fixing assembly. In this way, it is relatively convenient to take out the battery. As long as the vehicle cover is rotated and opened, and then the battery fixing assembly is unlocked.

[0003] With the change of vehicle models and the fuel-free of electric motorcycles, there have also appeared in the prior art solutions for further simplifying the structure of electric motorcycles. For example, an electric motorcycle with a patent publication number of CN220430382U and an application date of August 2023. In this patented technology, the battery is still placed in the battery compartment, but in this patent, the vehicle cover is omitted and an integrated seat is used instead, allowing the seat to extend above the battery, thereby using the seat to form a cover for the battery compartment, eliminating the vehicle cover / battery compartment cover in the prior art and making the structure more concise. At the same time, the extension of the seat also improves the comfort of the motorcycle.

[0004] However, the current such a solution has the following problems:

[0005] First, when the seat is disassembled, the battery can be directly seen, and the anti-theft function of the battery is slightly weak.

[0006] Second, the front end of the seat abuts against the edge and overlaps on the casing. In the case where the battery occupies a large area, only the edge of the front end of the seat is supported, resulting in poor force on the front end of the seat.

[0007] Second, the battery is still fixed from above or from the side above the battery by means of a limiting structure or a fixing structure alone. The internal movable space of the battery is relatively large. When the motorcycle is driving on bumpy roads, there is still a situation of battery shaking / vibration, which is not conducive to the fixation of the battery and the riding experience of the rider. Moreover, the shaking / vibration of the battery on the bumpy road is likely to cause the wires to become loose and lead to serious accidents. Summary of the Utility Model

[0008] The utility model aims to provide a motorcycle seat cushion to solve the problems of weak anti-theft function and poor force bearing at the front end of the seat cushion in the prior art when only the seat cushion is used to cover the top of the battery.

[0009] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0010] A motorcycle seat cushion comprises a seat cushion body which is detachably connected to a motorcycle, and a battery cover which is rotatably connected to a frame. A first locking structure is provided between the seat cushion and the frame, and the seat cushion extends forward along the length direction of the frame to above the battery cover.

[0011] The principle and advantage of this solution are: when this solution is adopted, because the seat body extends to the top of the battery cover, the motorcycle seat is ensured to have sufficient length to ensure comfort and overall simplicity of appearance. At the same time, a battery cover that can be rotatably opened is provided under the seat body, so that in order to take out the battery, in addition to disassembling the seat body, it is also necessary to open the battery cover before the battery can be easily taken out. Compared with the existing technology, it takes into account the simplicity of appearance while also improving the anti-theft function of the battery.

[0012] In addition, when adopting this solution, because the front end of the seat cushion body is directly pressed against the battery cover, the middle part of the seat cushion body can be directly in contact with the battery cover when the seat cushion body is designed, so that the seat cushion body is supported by the power of the battery cover, thereby improving the bearing strength of the seat cushion body.

[0013] Preferably, as an improvement, there is a concave-convex fit between the portion of the seat cushion body extending to the battery cover and the battery cover, so that the portion of the seat cushion body extending to the battery cover can be positioned and limited with the battery cover through the concave-convex fit.

[0014] The utility model also provides a battery cover assembly, including the motorcycle seat cushion, and also includes a battery cover plate for pressing the battery from above, one end of the battery cover plate is rotatably connected to the motorcycle frame, and a first locking structure is provided between the other end and the frame.

[0015] When this solution is adopted, the seat cushion transfers its weight to the battery cover, and the battery cover then presses the battery from the top, so that during driving, the battery can be compressed by the weight of the rider, thereby reducing the probability of battery shaking. It is also convenient to place batteries with larger discharge capacity in the same battery accommodation space, so as to improve the vehicle's endurance configuration while ensuring that the volume of the vehicle remains unchanged.

[0016] Preferably, as an improvement, an elastic pressing block is fixed under the battery cover, and the elastic pressing block is used to press against the top of the battery after the battery cover is restricted by the first lock structure, so as to reduce vibration while ensuring that the battery is pressed tightly.

[0017] Preferably, as an improvement, the first lock structure includes a lock hook and a lock catch. The lock hook includes a fixedly installed seat body, a driving bolt rotatably connected to the seat body, a handle rotatably connected to the driving bolt. A latching portion for latching with the handle is fixed on the seat body. The handle includes a latching portion and a pushing plate formed integrally and located on both sides of the rotation center. The latching portion is used for latching with the latching portion. A torsion spring is sleeved on the rotation center of the handle. One end of the torsion spring abuts against the lower part of the pushing plate, and the other end of the torsion spring abuts against the driving bolt. The driving bolt is located above the pushing plate and can abut against the pushing plate. A hook body is also rotatably connected to the driving bolt. The hook body can be latched with the lock catch. One of the lock hook and the lock catch is installed on the frame and the other is installed on the battery cover plate.

[0018] Advantageous effects: When adopting this solution, when it is necessary to unlock the first lock structure, only the driving bolt needs to be rotated. When the driving bolt is rotated, the driving bolt presses the pushing plate of the handle, so that the handle rotates against the elastic force of the torsion spring. After the handle rotates, the latching portion disengages from the latching portion on the seat body, so that the driving bolt can rotate freely around the rotation center. Under free rotation, the hook body can be disengaged from the lock catch, thus releasing the latching of the first lock structure and facilitating the opening of the battery cover plate. When the battery cover plate is pressed down and closed, only need to first hook the hook body on the lock catch, and then rotate the driving bolt to drive the latching portion of the handle to latch with the latching portion of the seat body again. After the latching is completed, the hook body will no longer be disengaged from the lock catch; the entire unlocking and locking process is simple and convenient to operate.

[0019] Preferably, as an improvement, a gas spring is rotatably connected to the frame. One of the pressure cylinder and the piston rod of the gas spring is rotatably connected to the frame, and the other is rotatably connected to the bottom of the battery cover plate, so that after the first lock structure is unlocked, the battery cover plate can be automatically opened by the gas spring.

[0020] It also includes a surrounding limiting member fixed on the frame for limiting the side of the battery. The surrounding limiting member limits around the battery to reduce the shaking of the battery during driving.

[0021] The surrounding limiting member includes a front limiting member, side limiting members located on the left and right sides of the battery, and a rear limiting member located at the rear of the battery. The front limiting member and the rear limiting member limit the battery from the front and rear. By the surrounding limiting member, the limiting of the battery is improved, and the shaking of the battery during the motorcycle driving is reduced.

[0022] Preferably, as an improvement, each of the four-sided limit members includes a protrusion protruding towards the side wall of the battery, and the protrusion faces a recessed area provided on the side wall of the battery, so as to further increase the front-back, left-right limit on the battery and prevent the battery from shaking. In addition, when a thief wants to directly lift out the battery after opening the battery cover in the conventional way, the protrusion will be restricted within the recessed area on the side wall of the battery, thus blocking the thief from directly lifting away the battery. If the thief wants to steal the battery, he will surely need to disassemble the semi-frame to complete it, which greatly increases the difficulty of theft and thus improves the security.

[0023] Preferably, as an improvement, the four-sided limit members are made of elastic limit members or plastic materials with toughness, so as to improve the shock absorption performance after vibration or extrusion occurs. At the same time, when the battery cover is opened and the battery is lifted upwards, only a relatively large force needs to be provided to lift out the battery without disassembling the four-sided limit members, which helps to improve the anti-theft performance and takes into account the convenience of battery disassembly and assembly.

[0024] The present utility model also provides a motorcycle, which includes the battery pressing cover assembly installed on the frame, and further includes a receiving box fixed on the frame. The receiving box is located behind the battery and is located below the seat body, so as to increase the receiving space of the motorcycle through the setting of the receiving box.

[0045] Embodiment 1

[0046] Combined withFigures 1 to 4 , a motorcycle seat cushion, including a seat cushion body 6. The seat cushion body 6 is detachably connected to the motorcycle and is located above the battery cover 7 that can be flipped open. The seat cushion body 6 extends forward along the length direction of the vehicle frame 1 above the battery cover 7, and the seat cushion body 6 can abut against the battery cover 7 to press the battery cover 7 tightly. In addition, to improve the cooperation between the seat cushion body 6 and the battery cover 7, a hanging bushing 61 is fixedly installed on the seat cushion body 6. The hanging bushing 61 is clamped by the cushion pad and the housing of the seat cushion body 6. A jack 71 is opened on the battery cover 7, and the hanging bushing 61 can be inserted into the jack 71 to achieve concave-convex cooperation.

[0047] When adopting this embodiment, not only the space above the battery 2 is blocked by the seat cushion body 6, but also the space above the battery 2 is blocked by the battery cover 7, which increases the difficulty of removing the battery 2, thereby improving the anti-theft function.

[0048] In addition, the seat cushion is designed to extend above the battery cover 7, making the seat cushion more simple and generous and more comfortable.

[0049] Embodiment Two

[0050] Combined with Figure 5 , this embodiment also provides a battery pressing cover assembly, including the above-mentioned motorcycle seat cushion, and further including a battery cover 7 for pressing the battery 2 from above. The left end of the battery cover 7 is rotatably connected to the motorcycle frame 1, and there is a first locking structure 8 between the right end and the frame 1. The number of the first locking structures 8 in this embodiment is 2. The first locking structure 8 is used to lock the battery cover 7 to the frame 1.

[0051] An air spring 72 is rotatably connected to the frame 1. The air spring 72 is also called a hydraulic strut. One of the pressure cylinder and the piston rod of the air spring 72 is rotatably connected to the frame 1, and the other is rotatably connected to the bottom of the battery cover 7. In this embodiment, the pressure cylinder of the air spring 72 is rotatably connected to the frame 1, and the free end of the piston rod of the air spring 72 is rotatably connected to the bottom of the battery cover 7.

[0052] An elastic pressing block 73 is fixed below the battery cover 7. The elastic pressing block 73 is used to abut against the top of the battery 2 after the battery cover 7 is restricted by the first locking structure 8. In this embodiment, the elastic pressing block 73 is made of an elastic rubber block. The elastic pressing block 73 of this embodiment presses on the hard handle 20 of the battery 2. The hard handle 20 is arched and arched upward. By setting the hard handle 20, it is convenient to press the battery 2 from the top of the battery 2 by using the hard handle 20, and it is also convenient to directly lift the battery 2 when the battery 2 is taken out upward.

[0053] In this embodiment, through the design of the elastic pressing block 73 and the seat cushion body 6 in Embodiment 1 abuts against the battery cover plate 7, after the rider sits on the seat cushion, the weight of the rider will be transmitted from the seat cushion body 6 through the battery cover plate 7 to the elastic pressing block 73, so that the elastic pressing block 73 presses the battery 2 tightly. Ensure that during driving, even on bumpy roads, the battery 2 can be firmly pressed to reduce the amplitude of vibration. Compared with the prior art that only relies on the form of the limiting member, this embodiment utilizes the weight of the rider to ensure the stability of the battery 2, reduce the impact on the battery 2, and improve the riding experience at the same time.

[0054] In addition, the battery 2 should be directly pressed by the elastic pressing block 73 under the battery cover plate 7, so that the top of the battery 2 can be closer to the battery cover plate 7. Thus, in the same planar space, the height of the battery 2 in this embodiment can be designed higher, thereby increasing the capacity of the battery 2 and increasing the endurance of the motorcycle without increasing its size.

[0055] In addition, the presence of the first lock structure 8 makes it necessary to unlock the first lock structure 8 first to remove the battery 2 after the seat cushion body 6 is removed, improving the anti-theft performance of the battery 2.

[0056] To improve the stable installation of the seat cushion, a second lock structure 62 and a fastening component 63 are provided between the seat cushion and the vehicle frame 1. One of the second lock structure 62 and the fastening component 63 is located in a section in the middle of the seat cushion, and the other is located in a section at the tail of the seat cushion. In this embodiment, the second lock structure 62 is located in a section at the tail of the seat cushion, and the fastening component 63 is located in a section in the middle of the seat cushion; the second lock structure 62 includes a lock seat 621 and a lock core 622. If one of the lock seat 621 and the lock core 622 is fixed on the vehicle frame 1, the other is fixed on the seat cushion. In this embodiment, the lock seat 621 is fixed on the vehicle frame 1, and the lock core 622 is fixed at the bottom of the seat cushion. The second lock structure 62 is a conventional mechanical lock structure that realizes unlocking through a cable. After inserting the key and turning the key, the second lock structure 62 is unlocked.

[0057] The fastening component 63 includes a wedge surface member 631 and a fastening door 632 that are matched with a wedge surface. If one of the wedge surface member 631 and the fastening door 632 is fixed on the vehicle frame 1, the other is fixed on the seat cushion. The fastening door 632 is provided with a wedge surface, and the wedge surface member 631 and the fastening door 632 are matched through the wedge surface. After the seat cushion slides along the vehicle frame 1, the wedge surface member 631 can be inserted into the fastening door 632 to realize the upper and lower fastening of the wedge surface member 631 and the fastening door 632, improving the stability of the seat cushion on the vehicle frame 1. In this embodiment, the wedge surface member 631 is integrally formed at the lower part of the shell of the seat cushion body 6, and the fastening door 632 is fixed on the vehicle frame 1.

[0058] In this embodiment, the front, middle, and rear positions of the seat cushion are defined by the concave-convex fit between the second locking structure 62, the fastening assembly 63, and the seat cushion body 6 and the battery cover 7, improving the stability of the seat cushion on the motorcycle.

[0059] Embodiment Three

[0060] Combined with Figures 6 to 9 , in this embodiment, a specific design is made for the first locking structure 8. The first locking structure 8 includes a locking hook 81 and a lock catch 82. The locking hook 81 includes a fixed seat body 811, a driving bolt 812 rotatably connected to the seat body 811. A clasping hand 813 is rotatably connected to the driving bolt 812. A clasping portion for clasping with the clasping hand 813 is fixed on the seat body 811. The clasping hand 813 includes a clasping portion 8131 and a pushing plate 8132 formed integrally and located on both sides of the rotation center. The clasping portion 8131 is used for clasping with the clasping portion. A torsion spring 8133 is sleeved on the rotation center of the clasping hand 813. One end of the torsion spring 8133 abuts against the lower part of the pushing plate 8132, and the other end of the torsion spring 8133 abuts against the driving bolt 812. The driving bolt 812 is located above the pushing plate 8132 and can abut against the pushing plate 8132. A hook body 814 is also rotatably connected to the driving bolt 812. The hook body 814 and the lock catch 82 can be clasped. If one of the locking hook 81 and the lock catch 82 is installed on the vehicle frame 1, the other is installed on the battery cover 7. In this embodiment, the seat body 811 of the locking hook 81 is fixed on the battery cover 7, and the lock catch 82 is fixed on the vehicle frame 1.

[0061] When this embodiment is adopted, when it is necessary to unlock the first locking structure 8, only the driving bolt 812 needs to be rotated. When the driving bolt 812 is rotated, the driving bolt 812 presses the pushing plate 8132 of the clasping hand 813, causing the clasping hand 813 to rotate against the elastic force of the torsion spring 8133. After the clasping hand 813 rotates, the clasping portion 8131 disengages from the clasping portion on the seat body 811, enabling the driving bolt 812 to rotate freely around the rotation center. Under free rotation, the hook body 814 can be disengaged from the lock catch 82, thus releasing the clasping of the first locking structure 8 and facilitating the opening of the battery cover 7. When the battery cover 7 is pressed down to close, only need to first hook the hook body 814 on the lock catch 82, and then rotate the driving bolt 812 to make the driving bolt 812 drive the clasping portion 8131 of the clasping hand 813 to clasp with the clasping portion of the seat body 811 again. After the clasping is completed, the hook body 814 will no longer be disengaged from the lock catch 82; the entire unlocking and locking process is simple and convenient to operate.

[0062] Embodiment Four

[0063] Combined with Figures 10 to 18 , Embodiment Four makes a further optimized design on the basis of Embodiment Two and / or Embodiment Three, specifically as follows:

Specifically, the surrounding limiting member includes a front limiting member 15, side limiting members 14 located on the left and right sides of the battery 2, and a rear limiting member 16 located at the rear of the battery 2. The front limiting member 15 and the rear limiting member 16 limit the battery 2 from the front and rear, and the limiting of the battery 2 is improved through the surrounding limiting member, avoiding the shaking of the battery 2 during the running of the motorcycle.

[0065] The surrounding limiting members all include a protrusion 141 protruding towards the side wall of the battery 2, and the protrusion 141 is opposite to a recessed area 21 provided on the side wall of the battery 2; the surrounding limiting members adopt elastic limiting members or a plastic material with toughness (such as PP material), so as to improve the shock absorption performance after vibration or extrusion occurs, and at the same time, when the battery cover 7 is opened and the battery 2 is lifted upwards, only a relatively large force needs to be provided to lift the battery 2 without disassembling the surrounding limiting members, which helps to improve the anti-theft performance and takes into account the convenience of the disassembly and assembly of the battery 2.

[0066] In this embodiment, the side limiting members 14 on the left and right sides are fixed on the inner wall of the vehicle frame 1, so as to block the side limiting members 14 through the vehicle frame 1, improving the aesthetics while making it difficult for thieves to know which structure specifically restricts the battery 2, thereby increasing the difficulty of theft and improving the safety.
