Description

Technical Field

[0001] This disclosure relates to the field of vehicle technology, and more particularly to a mobility scooter seat and a mobility scooter. Background Technology

[0002] With the accelerating aging of the population, mobility scooters for the elderly have become an important tool for short-distance travel due to their ease of operation and stable ride. As the core load-bearing component of the scooter, the seat's structural design directly affects user convenience, space utilization, and passenger safety, while the folding function is one of the key indicators for evaluating the practicality of a mobility scooter.

[0003] The folding function in a mobility scooter usually requires an articulated structure. Traditional articulated structures do not have a specific anti-loosening solution designed for the dynamic usage scenarios at the articulation points, making the bolts at the articulation connection points easy to loosen. Summary of the Invention

[0004] This disclosure provides a mobility scooter seat and a mobility scooter to at least solve the above-mentioned technical problems existing in the prior art.

[0005] The first aspect of this disclosure provides a personal mobility vehicle seat, including: a base, a seat bracket, a folding bracket, a support frame, a locking component, and an anti-loosening component; The two ends of the support frame are rotatably connected to the base and the seat bracket, respectively. One end of the folding bracket is rotatably connected to the seat bracket, and the other end of the folding bracket is rotatably connected to the base through a first rotating member, so that the base, the seat bracket, the folding bracket and the support frame form a quadrilateral structure. The locking component is disposed on the seat bracket so that when the seat bracket moves to a preset position, the folding bracket is locked. The anti-loosening component is fixedly connected to the base, and the anti-loosening component cooperates with the first rotating component to restrict the movement of the first rotating component.

[0006] Furthermore, the anti-loosening component includes a sleeve, a support column, and a limiting member; One end of the support column is fixedly connected to the base, and the other end of the support column is fixedly connected to the sleeve; The first rotating member passes through the sleeve, the limiting member is threadedly engaged with the sleeve, and the end of the limiting member near the first rotating member abuts against the first rotating member.

[0007] Furthermore, the base includes a first support and a second support spaced apart from each other; The number of folding brackets is two, namely a first folding bracket and a second folding bracket; The first folding bracket is provided with a first rotating hole, and the second folding bracket is provided with a second rotating hole. The first rotating component passes through the first rotating hole, the sleeve and the second rotating hole and is rotatably connected to the first support and the second support.

[0008] Furthermore, the two ends of the sleeve abut against the first folding bracket and the second folding bracket, respectively.

[0009] Furthermore, the first support is provided with a threaded hole, and the second support is provided with a mounting hole; The first rotating component is a first bolt, which passes through the mounting hole, the first rotating hole, the sleeve, and the second rotating hole in sequence before being threaded into the threaded hole. Furthermore, a nut is provided at the end of the support column away from the sleeve; The nut is connected to the base by fasteners.

[0010] Furthermore, the seat bracket has a sliding groove, and the folding bracket has a locking slot; The locking component includes a sliding member that slides in conjunction with the slide groove. When the sliding member engages with the slot, the folding bracket is fixed relative to the base and the seat bracket.

[0011] Furthermore, the support frame and the seat bracket are rotatably connected via a second rotating member; The locking component includes an elastic element, one end of which is connected to the sliding element, and the other end of which is connected to the second rotating element.

[0012] Furthermore, the locking component includes a pull rod, which is connected to the sliding member. The second aspect of this disclosure provides a mobility scooter, including the mobility scooter seat described in the first aspect.

[0013] The technical solution provided in this disclosure has the following advantages compared with the prior art: The mobility scooter seat provided in this embodiment includes a base, a seat frame, a folding bracket, a support frame, a locking component, and an anti-loosening component. Both ends of the support frame are rotatably connected to the base and the seat frame, respectively. One end of the folding bracket is rotatably connected to the seat frame, and the other end of the folding bracket is rotatably connected to the base via a first rotating member. This forms a quadrilateral structure with the base, seat frame, folding bracket, and support frame, allowing the seat frame to move to different positions and thus enabling the seat to fold or unfold. The locking component is located on the seat frame to lock the folding bracket when the seat frame moves to a preset position. The anti-loosening component is fixedly connected to the base and cooperates with the first rotating member to restrict its movement. The fixed connection of the anti-loosening component to the base and its cooperation with the first rotating member to restrict its movement effectively reduces the possibility of loosening at the connection between the first rotating member and the base due to rotation (or long-term rotation) with the folding bracket during use, improving the stability, reliability, and safety of the seat structure. This not only ensures the stability of the seat structure but also reduces noise and wear caused by loosening at the connection between the first rotating member and the base, extending the seat's service life.

[0018] To make the objectives, features, and advantages of this disclosure more apparent and understandable, the technical solutions in the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this disclosure, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

[0019] Combination Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the mobility scooter seat provided in this embodiment includes a base 1, a seat bracket 2, a folding bracket, a support frame 4, a locking component 5, and an anti-loosening component 6. Both ends of the support frame 4 are rotatably connected to the base 1 and the seat bracket 2, respectively. One end of the folding bracket is rotatably connected to the seat bracket 2, and the other end of the folding bracket is rotatably connected to the base 1 via a first rotating component 7, so that the base 1, seat bracket 2, folding bracket, and support frame 4 form a quadrilateral structure, allowing the seat bracket 2 to move to different positions, thereby realizing the folding or unfolding function of the seat. The locking component 5 is disposed on the seat bracket 2 so that when the seat bracket 2 moves to a preset position, the folding bracket is locked. The anti-loosening component 6 is fixedly connected to the base 1, and cooperates with the first rotating component 7 to restrict the movement of the first rotating component 7. The base 1, seat bracket 2, folding bracket, and support frame 4 form a quadrilateral structure, which has a certain stability, can evenly distribute force, and withstand the user's weight as well as the vibration and impact generated during driving. Meanwhile, the locking component 5 locks the folding bracket when the seat support 2 moves to the preset position, further ensuring the stability of the seat during use and preventing the seat structure from loosening or deforming due to accidental rotation of the folding bracket, thus improving the reliability and safety of the seat. The anti-loosening component 6 is fixedly connected to the base 1 and cooperates with the first rotating component 7 to restrict the movement of the first rotating component 7. This effectively reduces the possibility of the first rotating component 7 loosening at the connection with the base 1 due to rotation (or long-term rotation) with the folding bracket during use, improving the stability, reliability, and safety of the seat structure. This not only ensures the stability of the seat structure but also reduces noise and wear caused by loosening at the connection between the first rotating component 7 and the base 1, extending the service life of the seat.

[0020] The first rotating component 7 can be a rotating shaft, a rotating rod, or a bolt, or at least any one or a combination of two of the above.

[0021] In some specific embodiments, the anti-loosening component 6 includes a sleeve 61, a support column 62, and a limiting member. One end of the support column 62 is fixedly connected to the base 1, and the other end of the support column 62 is fixedly connected to the sleeve 61. The support column 62, with one end fixed to the base 1 and the other end fixed to the sleeve 61, forms a rigid support structure, providing a stable mounting carrier for the first rotating component 7 and preventing the first rotating component 7 from shifting or shaking due to unstable support. The first rotating component 7 passes through the sleeve 61, and the limiting member 63 is threadedly engaged with the sleeve 61, with the end of the limiting member 63 near the first rotating component 7 abutting against it. The limiting member 63 and the sleeve 61 are threadedly engaged, and by rotating the limiting member 63, the abutting force between it and the first rotating component 7 can be precisely adjusted, firmly fixing the first rotating component 7 according to actual usage requirements and preventing loosening due to vibration, force, etc. The limiting member 63 directly abuts against the first rotating member 7, forming a physical block and restricting the movement space of the first rotating member 7 axially. Compared with the anti-loosening method that relies solely on the friction of the connecting member itself, it is more stable.

[0022] The limiting member 63 can be a bolt or a connector including a head and a rod, wherein the rod is threaded for threaded engagement with the sleeve 61.

[0023] In some specific embodiments, the base 1 includes a first support 11 and a second support 12 spaced apart; there are two folding brackets, namely a first folding bracket 31 and a second folding bracket 32; the first support 11 and the second support 12 of the base 1 are spaced apart, and together with the two symmetrical folding brackets, a balanced force-bearing structure is formed. When the seat is unfolded or folded, the external force can be evenly distributed to the two folding brackets, avoiding deformation or damage caused by excessive force on one side.

[0024] The first folding bracket 31 has a first rotating hole 311, and the second folding bracket 32 ​​has a second rotating hole 321. The first rotating component 7 passes through the first rotating hole 311, the sleeve 61, and the second rotating hole 321 and is rotatably connected to the first support 11 and the second support 12. The first rotating component 7 passes through the rotating holes of the two folding brackets and the sleeve 61, firmly connecting the two folding brackets and the base 1 into a whole, reducing the relative sway between the components and further improving the overall structural rigidity of the seat. The two folding brackets rotate synchronously around the first rotating component 7 and cooperate with the supports of the base 1, ensuring that the movement trajectories of the left and right sides are completely consistent during the folding or unfolding of the seat, and there will be no unilateral jamming or offset. The sleeve 61 is set between the first folding bracket 31 and the second folding bracket 32 ​​to axially limit the two folding brackets. Optionally, the first rotating component 7 passes through the sleeve 61, and the two can adopt a small clearance fit (such as a transition fit) to reduce the radial sway space of the first rotating component 7 in the sleeve 61. The overlapping sleeve 61 axially limits the two folding brackets (restricting the folding brackets from being squeezed in the middle or separated to the sides), which can prevent the folding brackets from generating additional stress on the first rotating component 7 due to displacement, and indirectly reduce the probability of the first rotating component 7 becoming loose.

[0025] like Figure 4 As shown, both the first folding bracket 31 and the second folding bracket 32 ​​are provided with a first bushing 91 and a second bushing 92. The first bushing 91 and the second bushing 92 are fixedly connected to the first folding bracket 31 or the second folding bracket 32, which can reduce friction and protect the first folding bracket 31 and the second folding bracket 32.

[0026] Optionally, the two ends of the sleeve 61 abut against two second bushings 92 respectively.

[0027] In some specific embodiments, the two ends of the sleeve 61 abut against the first folding bracket 31 and the second folding bracket 32, respectively. The abutment of the two ends of the sleeve 61 against the two folding brackets directly restricts the axial movement of the two folding brackets towards the center or towards the sides, preventing misalignment during folding, unfolding, or use. In conjunction with the first support 11 and the second support 12 of the base 1, it ensures that the two folding brackets always maintain a symmetrical state, preventing uneven force distribution on the left and right sides due to axial displacement, and avoiding deformation or damage to the brackets.

[0028] In some specific embodiments, the first support 11 is provided with a threaded hole, and the second support 12 is provided with a mounting hole; the first rotating component 7 is a first bolt, which passes sequentially through the mounting hole, the first rotating hole 311, the sleeve 61, and the second rotating hole 321 before being threadedly connected to the threaded hole. It should be noted that, as... Figure 4 As shown, the front end of the first bolt has threads, and the front end of the first bolt is threadedly connected to the threaded hole of the first support 11.

[0029] The first bolt passes through the mounting hole of the second support 12, the folding bracket, and the sleeve 61 in sequence, and then connects with the threaded hole of the first support 11 to form a through-type rigid connection. This connection method can firmly lock the two folding brackets and the two supports into a whole, greatly improving the impact resistance and deformation resistance of the folding structure and preventing the separation or shaking of parts during use. The threaded connection between the first bolt and the first support 11 has self-locking properties, and can resist external forces such as vibration and impact by relying on the friction between the threads, preventing the bolt from loosening on its own during long-term use, and achieving basic anti-loosening without relying on other anti-loosening components.

[0030] In some specific implementation methods, such as Figure 4 As shown, a nut 64 is provided at the end of the support column 62 away from the sleeve 61; the nut 64 is connected to the base 1 by a fastener 93, which can realize a detachable rigid connection between the anti-loosening component 6 and the base 1, while strengthening the support stability of the sleeve 61, making the anti-loosening structure more reliable and maintenance more flexible.

[0031] In some specific embodiments, the seat support 2 has a sliding groove 21, and the folding support has a locking slot 33; the locking component 5 includes a sliding member 51, which slides in conjunction with the sliding groove 21. When the sliding member 51 is engaged with the locking slot 33, the folding support is fixed relative to the base 1 and the seat support 2. When the sliding member 51 is engaged with the locking slot 33, the rigid fit of the mechanical structure directly restricts the rotation of the folding support, which can more stably withstand external forces during seat use, preventing the seat from collapsing or shifting due to accidental rotation of the folding support, thus greatly improving safety. When the sliding member 51 moves out of the locking slot 33, the folding support can rotate relative to the base 1 and the seat support 2, allowing the seat to fold.

[0032] The slider 51 can be a rod, a slider, or a rotating shaft.

[0033] In some specific embodiments, the support frame 4 and the seat bracket 2 are rotatably connected via the second rotating member 8; the locking component 5 includes an elastic member 52, which can be a spring. One end of the elastic member 52 is connected to the sliding member 51, and the other end of the elastic member 52 is connected to the second rotating member 8. When the folding bracket rotates to the preset position (the sliding member 51 slides into the slot 33), the tension of the elastic member 52 will drive the sliding member 51 to automatically slide along the slide groove 21 to the slot 33 and complete the locking, without the user having to manually push the sliding member 51, achieving the convenient effect of locking as soon as it is in place, which is especially suitable for the needs of scooter users to quickly adjust the seat. The elastic member 52 can apply a continuous preload to the sliding member 51, making the fit between the sliding member 51 and the slot 33 tighter and eliminating the gap between them. When unlocking, the user can push the sliding member 51 to overcome the force of the elastic member 52 to disengage from the slot 33. The elasticity of the elastic member 52 can buffer the movement speed of the sliding member 51 and avoid damage to the components due to excessive operation.

[0034] The second rotating component 8 can be a rotating shaft, a rotating rod, or a bolt, or at least any one or a combination of two of the above.

[0035] In some specific embodiments, the locking component 5 includes a pull rod 53, which is connected to the slider 51, providing the slider 51 with a precise and labor-saving operating carrier, completely solving the problem of inconvenient operation of the slider 51, and improving the reliability and security of the unlocking operation. The mobility scooter provided in this embodiment includes the mobility scooter seat provided in this embodiment. Since the mobility scooter and the mobility scooter seat provided in this embodiment have the same advantages, they will not be described again here.
