Description

Technical Field

[0001] This invention belongs to the field of personal mobility vehicle technology, and specifically relates to a storage structure and storage method for a personal mobility vehicle. Background Technology

[0002] As a means of transportation for people's daily travel, personal mobility vehicles are popular among consumers because they are easy to carry and have a high safety factor.

[0003] Currently available mobility scooters can be folded and unfolded for easy storage. However, the chassis of these scooters are relatively large, resulting in a significant space requirement when folded, making them inconvenient to store. The technology disclosed in Chinese utility model patent CN222793729U presents a chassis comprising a first chassis frame, a second chassis frame, and a locking mechanism. The first and second chassis frames are arranged opposite each other along a first direction, with the first chassis frame sliding relative to the second chassis frame to allow the chassis to be folded or unfolded. When the chassis is in the folded state, the first chassis frame slides onto the second chassis frame, with at least partial overlap between the two. The chassis is configured as a retractable chassis, capable of both unfolding and folding, thus resulting in a smaller space-consuming and portable mobility scooter when folded.

[0004] The aforementioned technology allows the base to be extended and folded for storage, but during the folding process, the folding seat and chassis cannot be linked. In actual folding and storage, the seat needs to be operated separately. Therefore, a more convenient folding and storage structure is needed for a commuter vehicle, which is convenient for users to fold and store, increases folding sales, and also achieves a small space occupation after folding, making it easy to store. Summary of the Invention

[0005] In order to overcome the shortcomings of the prior art, the present invention aims to provide a storage structure for a mobility scooter, which is easy to fold and occupies little space after folding, making it convenient to store, as well as a method for storing the mobility scooter.

[0006] The objective of this invention is achieved as follows:

[0007] A storage structure for a mobility scooter includes a chassis and a folding seat mounted on the chassis. The chassis includes a first frame and a second frame, with the first frame sliding relative to the second frame to allow the chassis to be folded or unfolded. A mounting bracket is slidably mounted on the second frame. The folding seat includes a folding bracket, a seat cushion mounted on the folding bracket, and a backrest mounted on the seat cushion. One folding bracket is hinged to the mounting bracket, and the other folding bracket is hinged to the second frame. The mounting bracket drives the folding seat to unfold or fold.

[0008] A third link is provided between the backrest and the folding bracket. One end of the third link is hinged to the second link, and the other end of the third link is hinged to the backrest.

[0009] A first rack is provided along the length of the mounting frame, a gear is provided on the second frame, and a second rack is provided along the length of the first frame. The gear is meshed between the first rack and the second rack.

[0010] During the folding or unfolding of the first and second frames, the gear meshes with the first rack and rotates, causing the mounting bracket and folding seat to fold or unfold relative to the second frame.

[0011] When the folding bracket is folded, the third link causes the backrest to fold outwards towards the seat cushion.

[0012] Further configured as follows: the folding bracket includes a first link and a second link, the lower end of the first link is hinged to the mounting bracket, the upper end of the first link is slidably connected to the seat cushion, the upper end of the second link is hinged to the seat cushion, and the lower end of the second link is hinged to the second frame.

[0013] The seat cushion has a horizontal sliding groove. When unfolded, the upper end of the first connecting rod abuts against one end of the sliding groove. When folded, the upper end of the first connecting rod slides to the other end of the sliding groove.

[0014] One end of the third link is hinged to the second link, and the other end of the third link is hinged to the backrest; when the folding bracket is folded, the third link drives the backrest to fold outwards towards the seat cushion.

[0015] The mounting bracket is further configured such that a third limiting groove is provided on the mounting bracket, one end of the rotating shaft of the gear extends into the third limiting groove, the mounting bracket slides in the length direction of the third limiting groove, and the third limiting groove restricts the mounting bracket from disengaging from the second frame.

[0016] A further configuration includes a first locking device that secures and unfolds the mounting bracket and the second frame.

[0017] The first locking device includes a first fixing block disposed on the second frame and a first locking member hinged to the mounting bracket. After the first locking member is connected to the first fixing block, it restricts the mounting bracket from sliding relative to the second frame.

[0018] The first locking member is further configured such that one end is hinged to the mounting bracket, and the other end of the first locking member is provided with a locking slot that engages with the first fixing block; a first reset member is provided on the first locking member, and the first reset member drives the locking slot to remain locked with the first fixing block.

[0019] The mounting bracket is further configured such that an operating component is hinged to the mounting bracket, the middle part of the operating component is hinged to the mounting bracket, and the inner and outer ends of the operating component form a "7" shape.

[0020] In the locked state: the inner end of the operating member abuts against the first locking member, restricting the first locking member from swinging open relative to the hinge point.

[0021] Further configured as follows: an operating component is hinged on the mounting frame, the middle part of the operating component is hinged to the mounting frame, the inner end of the operating component is movably connected to the first locking component to form a hinge section, the outer end of the operating component extends outward to form an operating section, the hinge section and the operating section are in the shape of a "7", the first locking component is provided with a movable groove, and the hinge column on the hinge section is slidably disposed in the movable groove.

[0022] In the locked state: the operating section moves the hinge section to one end of the movable groove due to gravity, the first locking member is abutted by the hinge section and restricted from swinging open relative to the hinge point. The operating section causes the operating member to drive the hinge pin of the hinge section to slide and abut to the other end of the movable groove, and causes the first locking member to swing around the hinge axis of the first locking member, so that the lock opening is opened with the first fixed block.

[0023] A further feature is provided: a second locking device is provided between the folding bracket and the seat cushion to secure the two together;

[0024] The second locking device includes a second locking member hinged to the seat cushion, a sliding rod at the upper end of the folding bracket, a sliding groove on the seat cushion of the folding seat, the sliding rod sliding in the sliding groove, and a second locking port on the second locking member that engages with the sliding rod.

[0025] The seat cushion is further configured to have a fixing device that keeps the second locking member in an open and locked state.

[0026] The fixing device includes a first limiting groove and a second limiting groove provided on the seat cushion. The second locking member is provided with a fixing rod that is adapted to the first limiting groove and the second limiting groove. When the fixing rod is connected and fixed to the first limiting groove, the second locking member remains in a fixed state of being engaged with the sliding rod. When the fixing rod is connected and fixed to the second limiting groove, the second locking port remains in a state of being disengaged from the sliding rod.

[0027] A method for storing a personal mobility vehicle: including the storage structure described above, the specific steps include:

[0028] Step A: Move the fixing rod from the first limiting groove to the second limiting groove so that the second locking member is disengaged from the sliding rod. The fixing rod and the second limiting groove fix the second locking member and the sliding rod in an open state.

[0029] Step B: Operate the operating component to make the first locking component swing, so that the latch is disengaged from the first fixing block;

[0030] Step C: Continue pulling the operating component. The mounting bracket moves inward toward the first frame. The first rack drives the gear to rotate. The gear meshes with the second rack. The rotating gear drives the second frame to move inward toward the first frame.

[0031] Step D: The lower end of the first link moves inward with the mounting bracket, and the upper end of the second link slides to the other end of the sliding groove, causing the first and second links to be retracted downward. One end of the third link moves downward with the second link, and the other end of the third link drives the backrest to fold outward.

[0032] The advantages of this invention over the prior art are as follows:

[0033] 1. Through the gear and rack mechanism, the chassis can move the mounting frame during lateral folding, creating a linkage during the lateral movement. Users do not need to operate the mounting frame separately, nor do they need to fold and unfold the folding bracket separately. At the same time, the folding seat is connected to the mounting frame and the second frame through the structure of the first and second links, and the third link is connected to the second link and the backrest. This allows the folding seat to unfold and fold during the movement of the mounting frame, causing the backrest to fold outwards towards the seat cushion, making it convenient for users to fold and unfold. The operation is simple.

[0034] Second, the first locking device enables the locking and unlocking of the mounting bracket and the second frame, facilitating use; the second locking device enables the locking and unlocking of the folding bracket and the seat cushion; at the same time, the combined use of the first and second locking devices provides a double safety measure to prevent accidental opening.

[0035] Third, the vehicle can be stored using this structure, making it convenient for users to store the chassis and folding seat together. The backrest folds outward, making the folded vehicle even lower and the entire product more flat. Attached Figure Description

Detailed Implementation

[0051] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0052] See Figures 1 to 13As shown, a storage structure for a mobility scooter includes a chassis 1 and a folding seat 2 mounted on the chassis 1. The chassis 1 includes a first frame 11 and a second frame 12. The first frame 11 slides relative to the second frame 12 to allow the chassis 1 to be stored or unfolded. A mounting bracket 13 is slidably mounted on the second frame 12. The folding seat 2 includes a folding bracket 21. One folding bracket 21 is hinged to the mounting bracket 13, and the other folding bracket 21 is hinged to the second frame 12. The mounting bracket 13 drives the folding seat 2 to unfold or be stored.

[0053] A first rack 41 is provided along the length of the mounting frame 13, and a gear 42 is provided on the second frame 12. The gear 42 and the first rack 41 are meshed together.

[0054] During the folding or unfolding of the first frame 11 and the second frame 12, the gear 42 meshes with the first rack 41 and rotates, causing the mounting bracket 13 and the folding seat 2 to fold or unfold relative to the second frame 12. This structure allows the chassis 1 to move the mounting bracket 13 during lateral folding, creating a linkage during lateral movement. The user does not need to operate the mounting bracket 13 separately, nor does the user need to fold or unfold the folding bracket 21 separately, making folding and unfolding convenient and simple to operate.

[0055] The folding seat 2 includes a seat cushion 22 mounted on a folding bracket 21. The folding bracket 21 includes a first connecting rod 211 and a second connecting rod 212. The lower end of the first connecting rod 211 is hinged to the mounting frame 13, and the upper end of the first connecting rod 211 is slidably connected to the seat cushion 22. The upper end of the second connecting rod 212 is hinged to the seat cushion 22. The hinge between the second connecting rod 212 and the seat cushion 22 can be a direct hinge or an indirect hinge with other rods. For example, the second connecting rod 212 is hinged to the first connecting rod 211. The first connecting rod 211, the second connecting rod 212, the second frame 12, and the mounting frame 13 together form a triangular support structure. The second frame 12 and the mounting frame 13 together form the bottom edge of the triangular support. The lower end of the second connecting rod 212 is hinged to the second frame 12.

[0056] The seat cushion 22 has a horizontally arranged sliding groove 222. In the unfolded state, the upper end of the first connecting rod 211 abuts against one end of the sliding groove 222. In the folded state, the upper end of the first connecting rod 211 slides to the other end of the sliding groove 222. Through the structure of the first connecting rod 211 and the second connecting rod 212, and their connection with the mounting frame 13 and the second frame 12, the folding seat 2 can be unfolded and folded during the movement of the mounting frame 13, facilitating user operation.

[0057] The folding seat 2 includes a backrest 23 mounted on a seat cushion 22. A third link 3 is provided between the backrest 23 and the folding bracket 21. One end of the third link 3 is hinged to a second link 212, and the other end of the third link 3 is hinged to the backrest 23. When the folding bracket 21 is folded, the third link 3 drives the backrest 23 to fold outward from the seat cushion 22.

[0058] The first connecting rod 211 and the second connecting rod 212 are arranged in an "X" shape. One end of the third connecting rod 3 is hinged to the upper end of the second connecting rod 212. During the downward retraction of the second connecting rod 212, one end of the third connecting rod 3 is driven to move downward. The other end of the third connecting rod 3 is hinged to the backrest 23, and the hinge point is located above the hinge between the backrest 23 and the seat cushion 22. The upper end of the first connecting rod 211 moves towards the other end of the sliding groove 222. The side of the seat cushion 22 that is hinged to the backrest 23 swings towards the second connecting rod 212. The third connecting rod 3 drives the backrest 23 to swing outward, thereby realizing the folding of the backrest 23 outward. To facilitate the folding of the backrest 23, the end of the third connecting rod 3 that is hinged to the backrest 23 can be bent; alternatively, the end of the third connecting rod 3 that is hinged to the backrest 23 can be movably connected to the backrest 23 via a movable rod.

[0059] A second rack 43 is provided along the length of the first frame 11, and a gear 42 is meshed between the first rack 41 and the second rack 43. Through the gear 42 transmission of the two racks and the gear 42, the storage or unfolding of the first frame 11 and the second frame 12 can be synchronized with the storage and unfolding of the mounting frame 13 and the second frame 12. At the same time, the transmission efficiency of the two racks is faster and more stable, which facilitates the operation and storage.

[0060] The mounting bracket 13 is provided with a third limiting groove 131. One end of the rotating shaft of the gear 42 extends into the third limiting groove 131. The mounting bracket 13 slides along the length of the third limiting groove 131, which restricts the mounting bracket 13 from disengaging from the second frame 12. Users can move directly within the third limiting groove 131 during unfolding and folding without worrying about excessive movement; operation is convenient.

[0061] Meanwhile, in order to facilitate the smooth and stable movement of the mounting frame 13, a guide rib 110 is provided on the first frame 11, and a guide groove 132 adapted to the guide rib 110 is provided on the mounting frame 13. The guide groove 132 moves laterally along the guide rib 110.

[0062] In order to fix the mounting bracket 13 and the second frame 12 in the unfolded state: a first locking device is provided between the mounting bracket 13 and the second frame 12 to fix the two in the unfolded state.

[0063] The first locking device includes a first fixing block 51 disposed on the second frame 12 and a first locking member 52 hinged to the mounting bracket 13. After the first locking member 52 is connected to the first fixing block 51, it restricts the mounting bracket 13 from sliding relative to the second frame 12. The first locking member 52 and the first fixing block 51 cooperate to achieve locking. The first fixing block 51 can be a round rod connecting both sides of the second frame 12 or a round rod disposed on one side of the second frame 12.

[0064] The specific structure is as follows: one end of the first locking member 52 is hinged to the mounting bracket 13, and the other end of the first locking member 52 is provided with a locking slot 521, which is engaged with the first fixing block 51; a first reset member 525 is provided on the first locking member 52, which drives the locking slot 521 to remain locked with the first fixing block 51. The first reset member 525 is a tension spring or a torsion spring, and in this embodiment, a torsion spring is preferred. The first locking member 52 is hinged to the mounting bracket 13 through a hinge shaft, and the torsion spring is sleeved on the hinge shaft. One end of the torsion spring abuts against the mounting bracket 13, and the other end of the torsion spring abuts against the first locking member 52. The torsion spring drives the first locking member 52 to remain engaged with the first fixing block 51.

[0065] In this embodiment, an operating member 6 is hinged to the mounting bracket 13. The middle part of the operating member 6 is hinged to the mounting bracket 13. The inner and outer ends of the operating member 6 form a "7" shape, which acts as a lever for easy operation by the user. In the locked state, the inner end of the operating member 6 abuts against the first locking member 52, restricting the first locking member 52 from swinging open relative to the hinge point. When unlocking is required, the user operates the outer end to release the inner end from the abutment restriction with the first locking member 52, making it easy for the user to open the first locking member 52. The operating member 6 and the first locking member 52 can be operated independently. The operating member 6 only abuts against and fixes or unlocks the first locking member 52. Alternatively, the operating member 6 and the first locking member 52 can be linked. After the operating member 6 abuts against and fixes or unlocks the first locking member 52, the user can continue to operate the operating member 6 to unlock the first locking member 52 from the first fixing block 51.

[0066] Specifically, the structure of the operating component 6 is as follows: the operating component 6 is hinged on the mounting frame 13, the middle part of the operating component 6 is hinged to the mounting frame 13, the inner end of the operating component 6 is movably connected to the first locking component 52 to form a hinge segment 61, the outer end of the operating component 6 extends outward to form an operating segment 62, the hinge segment 61 and the operating segment 62 are in the shape of a "7", the first locking component 52 is provided with a movable groove 522, and the hinge post 63 on the hinge segment 61 is slidably disposed in the movable groove 522; the two ends of the movable groove 522 respectively form an abutment end 523 and an unlocking end 524.

[0067] In the locked state: the operating section 62 moves the hinge section 61 towards one end of the movable groove 522 due to gravity. At this time, the hinge pin 63 abuts against the abutting end 523, and the first locking member 52 is restricted by the hinge section 61 to swing open relative to the hinge point. Operating the operating section 62 causes the operating member 6 to drive the hinge pin 63 of the hinge section 61 to slide and abut against the other end of the movable groove 522. At this time, the hinge pin 63 abuts against the unlocking end 524, and the hinge pin 63 drives the first locking member 52 to swing around the hinge axis of the first locking member 52, so that the lock opening 521 opens with the first fixing block 51.

[0068] A second locking device is provided between the folding bracket 21 and the seat cushion 22 to fix the two together. At this time, the folding seat 2 can be locked. In the locked state, even if the first locking device is opened, it cannot be folded and stored. The second locking device realizes the locking and opening of the folding bracket 21 and the seat cushion 22. At the same time, the combined setting of the first locking device and the second locking device achieves a double insurance effect to prevent accidental opening.

[0069] Specifically, the second locking device includes a second locking member 71 hinged to the seat cushion 22, a sliding rod 72 at the upper end of the folding bracket 21, a sliding groove 222 on the seat cushion 22 of the folding seat 2, the sliding rod 72 sliding in the sliding groove 222, and a second locking slot 711 on the second locking member 71 that engages with the sliding rod 72.

[0070] In this embodiment, the first link 211 and the second link 212 are arranged in an "X" shape, and the intersection of the first link 211 and the second link 212 is hinged through a hinge shaft; a sliding rod 72 is provided at the upper end of the first link 211. For ease of production, the sliding rod 72 is a screw that is locked to the first link 211, or it can be a cylinder that is connected to the first link 211.

[0071] When the scooter is in the unfolded state, with both the first locking device and the second locking device locked, the two devices work together to provide double protection, preventing accidental unlocking and avoiding the scooter from folding due to the opening of one locking device, thus improving safety.

[0072] The seat cushion 22 is provided with a fixing device that keeps the second locking member 71 in the open and locked states. The fixing device keeps the second locking member 71 in the open and locked states, which facilitates the folding operation. When folding and storing, the fixing device can be opened first to keep the second locking member 71 in the open and locked states. Only after keeping it in the open state can the seat 2 and the mounting bracket 13 be folded and stored.

[0073] The specific structure is as follows: The fixing device includes a first limiting groove 223 and a second limiting groove 224 provided on the seat cushion 22. The seat cushion 22 is provided with a downwardly protruding convex plate 221. The convex plate 221 is provided with an arc-shaped groove 225. The two ends of the arc-shaped groove 225 form the first limiting groove 223 and the second limiting groove 224. The sliding groove 222 is also provided on the convex plate 221. The second locking member 71 is provided with a fixing rod 81 that is adapted to the first limiting groove 223 and the second limiting groove 224. When the fixing rod 81 is connected and fixed to the first limiting groove 223, the second locking member 71 remains in a locked state with the sliding rod 72. When the fixing rod 81 is connected and fixed to the second limiting groove 224, the second locking port 711 remains in a disengaged state from the sliding rod 72. In order to facilitate the movement of the fixing rod 81 in the first limiting groove 223 and the second limiting groove 224, the second locking member 71 is provided with a movable groove for the fixing rod 81 to move.

[0074] The second locking member 71 has a tension spring 82 between the hinge shaft 83 on the seat cushion 22 and the fixed rod 81. The tension spring 82 pulls the fixed rod 81 and the hinge shaft 83, and drives the fixed rod 81 to maintain abutment with the first limiting groove 223 or the second limiting groove 224. There is an arc-shaped guide surface 226 between the first limiting groove 223 and the second limiting groove 224. The fixed rod 81 moves between the first limiting groove 223 and the second limiting groove 224 through the guide surface 226.

[0075] A method for storing a mobility scooter: Specific steps include:

[0076] Step A: Move the fixing rod 81 from the first limiting groove 223 to the second limiting groove 224, so that the second locking member 71 is disengaged from the sliding rod 72. The fixing rod 81 and the second limiting groove 224 fix the second locking member 71 and the sliding rod 72 in an open state.

[0077] Step B: Operate the operating component 6 to make the operating component 6 drive the first locking component 52 to swing, so that the latch is disengaged from the first fixing block 51.

[0078] Step C: Continue pulling the operating component 6, the mounting bracket 13 moves inward to the inside of the first frame 11, the first rack 41 drives the gear 42 to rotate, the gear 42 meshes with the second rack 43, and the rotating gear 42 drives the second frame 12 to move inward to the inside of the first frame 11.

[0079] Step D: The lower end of the first link 211 moves inward with the mounting bracket 13, and the upper end of the second link 212 slides to the other end of the sliding groove 222, so that the first link 211 and the second link 212 are retracted downward. One end of the third link 3 moves downward with the second link 212, and the other end of the third link 3 drives the backrest 23 to fold outward.

[0080] The first rack 41 and the second rack 43 are of the same length. The gear 42 is located at the front end of the second frame 12. In the folded state, the tail end of the first rack 41 and the head end of the second rack 43 mesh with the gear 42. In the unfolded state, the head end of the first rack 41 and the tail end of the second rack 43 mesh with the gear 42. This folding method allows the first frame 11 and the second frame 12 to make full use of the internal space of the first frame 11 when folded. The backrest 23 of the folding seat 2 is folded outward, which can reduce the height after folding and reduce the space occupied compared to folding inward. The folding method of the mounting bracket 13 moving inward and the backrest 23 folding outward can make full use of the space in the length direction after the first frame 11 and the second frame 12 are folded, making the whole product more flat.

[0081] The mobility scooter also includes a foldable steering handle 9, which is a feature of existing technology. The folded chassis 1 and foldable seat 2 are located under the folded steering handle 9, making the entire mobility scooter easy to store and carry when folded.

[0082] The above embodiments are merely preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape, and principle of the present invention should be covered within the scope of protection of the present invention.
