Description

Technical Field

[0001] This invention relates to the field of detachable mobility scooter technology, and more specifically, to a detachable mobility scooter. Background Technology

[0002] With the increasing sophistication of transportation, personal mobility vehicles have gradually become a convenient tool for many people to travel short distances daily.

[0003] However, if a mobility scooter has a non-detachable, integral structure like a standard car, it would require larger transport components during transportation, thus increasing the difficulty of transport.

[0004] In addition, due to the complex mechanical transmission structure of the mobility scooter, it is quite difficult to achieve the following performance simultaneously: 1. The installer can easily disassemble and install the scooter; 2. The disassembly and assembly parts can maintain good stability when the scooter is in use; 3. The disassembly and assembly structure itself can not affect the normal use of other components on the scooter. Summary of the Invention

[0005] This invention provides a detachable mobility vehicle that overcomes some or all of the shortcomings of the prior art.

[0006] According to the present invention, a detachable mobility scooter includes a mobility scooter body, the mobility scooter body including a front body and a rear body that are detachably connected by a detachable structure, the detachable structure including a front detachable part located at the front body and a rear detachable part located at the rear body; the front detachable part and the rear detachable part are provided with connecting components that are connected and cooperate with each other on both sides in the horizontal longitudinal direction.

[0007] The front detachment has an L-shaped front connecting plate at the middle of its horizontal longitudinal direction, and an L-shaped abutment opening is formed at the front connecting plate; the rear detachment has a rear connecting plate at the middle of its horizontal longitudinal direction, and a vertically penetrating insertion groove is formed at the rear connecting plate; a pin assembly with a vertically penetrating abutment opening is provided between the front connecting plate and the insertion groove to limit the connection or separation of the two.

[0008] The mobility scooter of this invention can be divided into a front body and a rear body, so that the front body and the rear body can be transported or produced separately during transportation and production, thereby facilitating transportation and improving production efficiency.

[0009] It is worth noting that, compared with the prior art, the front and rear vehicle bodies in this invention are connected by a disassembly structure. During the installation process, the front and rear disassembly parts of the front and rear vehicle bodies are first aligned, and then the two sides of the front and rear disassembly parts are limited and connected in the horizontal and longitudinal direction by the connecting assembly, thereby achieving pre-positioning. Then, the pin assembly is inserted vertically into the insertion groove at the rear connecting plate, thereby limiting and connecting the middle of the front and rear disassembly parts in the horizontal and longitudinal direction as well. In addition, the two sides and the middle of the front and rear vehicle bodies are connected by the connecting assembly, thus ensuring better stability during use.

[0010] Specifically, during the disassembly process, the pin assembly is pulled upward from the insertion slot and the front vehicle body is rotated with the front wheel as the fulcrum, thereby disengaging the connecting components and completing the disassembly. The operation is simple and convenient.

[0011] Preferably, the pin assembly includes, from top to bottom, a handle, a pin seat for fastening with the front connecting plate, and a plug block for inserting into the plug slot. The lower part of the plug block protrudes horizontally toward the rear to form a limiting part, which is used to limit the plug slot in the vertical direction.

[0012] Specifically, during use, the plug block is inserted vertically into the plug slot, thereby creating a horizontal limit between the plug block and the plug slot; at the same time, the pin seat and the front connecting plate have corresponding screw holes, so that the pin seat and the front connecting plate can be fastened together by bolts.

[0013] Therefore, it can be understood that the limiting connection between the front detachable part and the pin assembly is achieved by the connection between the pin holder and the front connecting plate, and the limiting connection between the rear detachable part and the pin assembly is achieved by the connection between the insertion block and the insertion slot. Thus, the pin assembly can better serve as an intermediate transition to limit the connection between the front and rear detachable parts, and the connection process is simple. In this structure, it is only necessary to insert the insertion block into the insertion slot and then fasten the pin holder to the front connecting plate.

[0014] Furthermore, since the plug block is vertically inserted into the plug slot, the fit between the plug block and the plug slot cannot achieve vertical positioning. Therefore, the vertical positioning of the common connector formed by the pin assembly, the front disassembly part, and the rear disassembly part is only achieved through the fastening connection between the pin seat and the front connecting plate. However, since the vehicle is prone to bumps during driving, vertical vibration is likely to occur. As the usage time increases, the bolts are also prone to loosening due to repeated bumps, which directly affects the connection stability of the common connector.

[0015] Preferably, the limiting part includes a first limiting block located on the upper side and a second limiting slider located on the lower side. The first limiting block is used to abut against the rear connecting plate and is longer than the second limiting slider in the horizontal direction. A limiting groove is formed on the side wall of the horizontally upper side of the insertion groove, which is inclined from top to bottom for sliding cooperation with the second limiting slider. The L-shaped abutment opening at the front connecting plate includes a vertical through-hole in the vertical direction and a horizontal through-hole in the horizontal direction. A vertical connecting rod is connected between the handle and the pin seat, which can abut against the lower end wall of the horizontal through-hole. The vertical connecting rod is used to abut against the horizontal through-hole at an angle so that the second limiting slider can slide into the limiting groove.

[0016] Preferably, the connecting assembly includes two front axle fixing plates located at the front disassembly section. The two front axle fixing plates are arranged relatively parallel to each other along the horizontal longitudinal direction, and both front axle fixing plates are inclined towards the rear vehicle body side. The upper part of each of the two front axle fixing plates is provided with a first connecting rod extending to its outer side along the horizontal longitudinal direction, and the lower part of each of the two front axle fixing plates is provided with a second connecting part penetrating along the horizontal longitudinal direction.

[0017] Preferably, the second connecting part includes a second abutting surface in the shape of a semi-circular arc, a second steep slope surface that is abruptly connected to the second abutting surface on the side of the second abutting surface facing the front of the vehicle body, and a second sliding surface that is gently connected to the second abutting surface on the side of the second abutting surface facing the rear of the vehicle body.

[0018] Preferably, the connecting assembly includes two rear axle fixing plates at the rear detachment section. The two rear axle fixing plates are arranged relatively parallel to each other along the horizontal longitudinal direction. The upper part of the two rear axle fixing plates forms a first connecting part that extends through the horizontal longitudinal direction. The first connecting part is used to detachably connect with a first connecting rod. The lower part of the two rear axle fixing plates is provided with a second connecting rod that is arranged along the horizontal longitudinal direction and extends to its outer side. The second connecting rod is used to detachably connect with the second connecting part.

[0019] Preferably, the first connecting part includes a first abutting groove with an arc-shaped cross section arranged at an inclination. The first abutting groove has an opening on the side facing the front vehicle body for inserting the first connecting rod. The bottom wall of the first abutting groove is used to abut against the first connecting rod to cooperate with the weight of the first connecting rod to form a positioning. The upper end surface of the first abutting groove has a first arc-shaped surface for sliding guidance with the first connecting rod.

[0020] Preferably, a positioning frame arranged in a horizontal longitudinal direction is connected between the two front axle fixing plates. A square connecting slot is formed in the middle of the positioning frame. A bent pin fixing tube is provided at the connecting slot to engage with it. The lower end of the pin fixing tube is fixedly connected to a support tube provided at the front of the vehicle body, and the upper end of the pin fixing tube is vertically connected to the front connecting plate.

[0021] Preferably, a seat body is movably connected above the front connecting part; a seat positioning seat is fixedly connected to the lower middle part of each of the two front axle fixing plates and is arranged at an upward angle; a seat shaft hole and a positioning pin hole are formed in the horizontal longitudinal direction at the position of the two front axle fixing plates above the first connecting rod.

[0022] Preferably, a seat support rod is movably connected to the upper end of the seat positioning seat, the lower end of the seat support rod is movably connected to the seat positioning seat, and the upper end of the seat straight rod is connected to the seat body; a seat support plate is movably connected inside the seat shaft hole, and a positioning horizontal tube arranged in a horizontal longitudinal direction is connected between the upper ends of the two seat support plates, and a fixed U-shaped seat for fixed connection with the seat body is sleeved on the positioning horizontal tube.

[0023] The positioning pin hole is connected to a seat positioning pin arranged in the horizontal longitudinal direction. The seat positioning pin is used to screw into the positioning pin hole to position and connect with the seat support plate. Attached Figure Description

[0033] To further understand the content of this invention, a detailed description of the invention is provided in conjunction with embodiments. It should be understood that the embodiments are merely illustrative and not limiting of the invention.

[0034] Example 1

[0035] Combination Figure 1 This embodiment provides a detachable mobility scooter, which includes a scooter body 100. The scooter body 100 includes a front body 110 and a rear body 120 that are detachably connected by a detachable structure. Figure 4 and Figure 5 The disassembly structure includes a front disassembly part 400 located at the front body 110 and a rear disassembly part 500 located at the rear body 120; the front disassembly part 400 and the rear disassembly part 500 are provided with connecting components that connect and cooperate with each other on both sides in the horizontal longitudinal direction.

[0036] Combination Figure 2 and Figure 3 The front detachment part 400 has an L-shaped front connecting plate 410 at the middle of its horizontal longitudinal direction, and an L-shaped abutment opening 420 is formed at the front connecting plate 410; combined Figure 5 A rear connecting plate 510 is horizontally arranged at the middle of the rear disassembly section 500 in the longitudinal direction, and a vertically penetrating insertion groove 520 is formed at the rear connecting plate 510; combined with Figure 3 A pin assembly 300 is provided between the front connecting plate 410 and the insertion slot 520, with a vertically penetrating abutment opening 420 for limiting the connection or separation of the two.

[0037] Specifically, in this embodiment, the main body 100 of the mobility scooter can be divided into a front body 110 and a rear body 120, so that the front body 110 and the rear body 120 can be transported or produced separately during transportation and production, thereby facilitating transportation and improving production efficiency.

[0038] It is worth noting that, compared with the prior art, in this embodiment, the front vehicle body 110 and the rear vehicle body 120 are connected by a disassembly structure. During the installation process, the front disassembly parts 400 and 500 of the front vehicle body 110 and the rear vehicle body 120 are first aligned, and then the two sides of the front disassembly parts 400 and the rear disassembly parts 500 are limited and connected in the horizontal longitudinal direction by the connecting assembly, thereby achieving pre-positioning. Then, the pin assembly 300 is inserted vertically into the insertion groove 520 at the rear connecting plate 510, thereby limiting and connecting the middle of the front disassembly parts 400 and the rear disassembly parts 500 in the horizontal longitudinal direction as well. Then, the two sides and the middle of the front vehicle body 110 and the rear vehicle body 120 are assembled and connected with the connecting assembly.

[0039] Specifically, during the disassembly process, the pin assembly 300 is pulled upward from the insertion slot 520 and the front vehicle body 110 is rotated with the front wheel as the fulcrum, thereby causing the connecting assembly to disengage and thus completing the disassembly.

[0040] The detailed structure and principles are described below:

[0041] In this embodiment, combined with Figure 3 , Figure 4 as well as Figure 6 The pin assembly 300 includes, from top to bottom, a handle 310, a pin seat 320 for fastening with the front connecting plate 410, and a plug block 330 for inserting into the plug groove 520. The lower part of the plug block 330 protrudes horizontally to the rear to form a limiting part 340, which is used to limit the plug groove 520 in the vertical direction.

[0042] Specifically, during use, the plug block 330 is inserted vertically into the plug groove 520, thereby creating a horizontal limit between the plug block 330 and the plug groove 520; at the same time, the pin seat 320 and the front connecting plate 410 have corresponding screw holes, so that the pin seat 320 and the front connecting plate 410 can be fastened together by bolts.

[0043] Therefore, it can be understood that the limiting connection between the front detachable part 400 and the pin assembly 300 is achieved by the connection between the pin seat 320 and the front connecting plate 410, and the limiting connection between the rear detachable part 500 and the pin assembly 300 is achieved by the connection between the insertion block 330 and the insertion slot 520. Thus, the pin assembly 300 can better serve as an intermediate transition to limit the connection between the front detachable part 400 and the rear detachable part 500, and the connection steps are simple. In this structure, it is only necessary to insert the insertion block 330 into the insertion slot 520 and then fasten the pin seat 320 to the front connecting plate 410.

[0044] Furthermore, since the plug block 330 is vertically inserted into the plug slot 520, the fit between the plug block 330 and the plug slot 520 cannot achieve vertical positioning. Therefore, the vertical positioning of the common connector formed by the pin assembly 300, the front disassembly part 400, and the rear disassembly part 500 is only achieved through the fastening connection between the pin seat 320 and the front connecting plate 410. However, since the vehicle is prone to bumps during driving, vertical vibration is likely to occur. As the usage time increases, the bolts are also prone to loosening due to repeated bumps, which directly affects the connection stability of the common connector.

[0045] Therefore, furthermore, the limiting part 340 formed at the lower part of the plug block 330 in this embodiment can better limit the plug slot 520 and the plug block 330 in the vertical direction. The specific structural principle is described below:

[0046] In this embodiment, combined with Figure 6 The limiting part 340 includes a first limiting block 341 located on the upper side and a second limiting slider 342 located on the lower side. The first limiting block 341 is used to abut against the rear connecting plate 510 and is longer than the second limiting slider 342 in the horizontal direction. Figure 5 as well as Figure 8 The side wall of the insertion groove 520 is inclined from top to bottom and has a limiting groove 530 for sliding cooperation with the second limiting slider 342.

[0047] Combination Figure 7 and Figure 8 The L-shaped abutment opening 420 at the front connecting plate 410 includes a vertical through-hole 421 extending vertically and a horizontal through-hole 422 extending horizontally; a vertical connecting rod is connected between the handle 310 and the pin seat 320, which can abut against the lower end wall of the horizontal through-hole 422. The vertical connecting rod is used to tilt against the horizontal through-hole 422 so that the second limiting slider 342 can slide into the limiting groove 530.

[0048] Specifically, during use, the assembler can first place the vertical connecting rod against the lower end wall of the horizontal opening 422, thereby tilting the entire pin assembly 300 so that the second limiting slider 342 can slide tilted into the limiting groove 530; then slide until the first limiting block 341 abuts against the rear connecting plate 510 and cannot slide further, then restore the tilted pin assembly 300 to vertical. At this time, the first limiting block 341 facilitates the formation of a vertical abutment limit between the limiting grooves 530; then the pin seat 320 is fastened to the front connecting plate 410 with bolts. At this point, the common connecting body formed by the pin assembly 300, the front detachable part 400, and the rear detachable part 500 is assembled. The fastening connection can limit the pin assembly 300 and the front detachable part 400 in both the horizontal and vertical directions. The vertical abutment limit can limit the pin assembly 300 and the rear detachable part 500 in the vertical direction. The connection between the aforementioned insertion block 330 and the insertion slot 520 can limit the pin assembly 300 and the front detachable part 400 in the horizontal direction.

[0049] Therefore, the pin assembly 300 in this embodiment can stably assemble and connect the front detachable part 400 and the rear detachable part 500 with relatively simple assembly operations, making the operation convenient and the connection stable.

[0050] Understandably, when the pin assembly 300 returns to a vertical position, the first limiting block 341 and the limiting groove 530 no longer form a sliding fit. The inclined limiting groove 530 forms a vertical limit on the first limiting block 341, which means that the entire pin assembly 300 can form a better limiting fit with the rear disassembly part 500 in the vertical direction. This results in the common connection body formed by the pin assembly 300, the front disassembly part 400, and the rear disassembly part 500 having two limiting points in the vertical direction: a bolted fastening connection and a vertical limiting point between the first limiting block 341 and the limiting groove 530. This makes the connection of the entire common connection body more stable and also prevents the bolted fastening connection from wearing and loosening due to prolonged use and vibration, thus providing better safety.

[0051] Specifically, since the aforementioned pin assembly 300 can only connect the front vehicle body 110 and the rear vehicle body 120 in the middle of the horizontal longitudinal direction, but cannot connect the two on both sides of the horizontal longitudinal direction, it is still difficult to ensure the overall connection stability between the two.

[0052] Furthermore, the two are connected on both sides in the horizontal longitudinal direction by a connecting component, which can cooperate with the pin assembly 300 to realize the assembly and disassembly of the front body 110 and the rear body 120. The specific structural principle is as follows:

[0053] In this embodiment, combined with Figure 2 , Figure 3 and Figure 4 The connecting assembly includes two front axle fixing plates 210 located at the front disassembly section 400. The two front axle fixing plates 210 are arranged relatively parallel to each other along the horizontal longitudinal direction, and both front axle fixing plates 210 are inclined towards the rear vehicle body 120. The upper part of each of the two front axle fixing plates 210 is provided with a first connecting rod 220 extending to its outer side along the horizontal longitudinal direction, and the lower part of each of the two front axle fixing plates 210 is provided with a second connecting part 230 penetrating along the horizontal longitudinal direction.

[0054] In this embodiment, combined with Figure 3 and Figure 4 and Figure 9 The second connecting part 230 includes a second abutting surface 231 in the shape of a semi-circular arc. A second steep slope surface 232 is formed on the side of the second abutting surface 231 facing the front vehicle body 110 and is circumferentially connected to the second abutting surface 231. A second sliding surface 233 is formed on the side of the second abutting surface 231 facing the rear vehicle body 120 and is circumferentially connected to the second abutting surface 231.

[0055] In this embodiment, combined with Figure 3 and Figure 5The connecting assembly includes two rear axle fixing plates 540 at the rear detachment portion 500. The two rear axle fixing plates 540 are arranged relatively parallel to each other along the horizontal longitudinal direction. The upper part of the two rear axle fixing plates 540 forms a first connecting portion 550 that extends along the horizontal longitudinal direction. The first connecting portion 550 is used to detachably connect and cooperate with the first connecting rod 220. The lower part of the two rear axle fixing plates 540 is provided with a second connecting rod 560 that is arranged along the horizontal longitudinal direction and extends to its outer side. The second connecting rod 560 is used to detachably cooperate with the second connecting portion 230.

[0056] In this embodiment, the first connecting part 550 includes a first abutting groove 551 with an arc-shaped cross section arranged at an inclination. The first abutting groove 551 has an opening on the side facing the front vehicle body 110 for inserting the first connecting rod 220. The bottom wall of the first abutting groove 551 is used to abut and cooperate with the first connecting rod 220 to form a positioning in accordance with the gravity of the first connecting rod 220. The upper end surface of the first abutting groove 551 has a first arc-shaped surface 570 for sliding guidance with the first connecting rod 220.

[0057] Specifically, the first connecting rod 220 at the front axle fixing plate 210 and the first connecting portion 550 at the rear axle fixing plate 540 serve as the first connecting unit in the connecting assembly, and the second connecting rod 560 at the rear axle fixing plate 540 and the second connecting portion 230 at the front axle fixing plate 210 serve as the second connecting unit in the connecting assembly.

[0058] Specifically, for the first connecting unit, during use, the first connecting rod 220 can slide into the first abutment groove 551 at the first connecting portion 550; in its natural state, the first connecting rod 220 is positioned at the bottom wall of the first abutment groove 551. For the second connecting unit, during use, the second connecting rod 560 can be engaged at the second abutment surface 231 of the second connecting portion 230. Furthermore, since the second abutment surface 231 is circumferentially abutted by a second steep slope surface 232, the second connecting rod 560 is less likely to slide out along the second steep slope surface 232. In addition, the second abutment surface 231 has a circumferentially gently connected second sliding surface 233 on the side facing the rear vehicle body 120, making it easier for the second connecting rod 560 to slide out smoothly along the second sliding surface 233.

[0059] The specific usage and assembly principles are as follows:

[0060] During normal use, due to gravity, the front vehicle body 110 may tend to move downward with the front wheel as the fulcrum. At this time, the first connecting rod 220 at the front vehicle body 110 may move along the lower bottom wall of the first abutment groove 551. At this time, the second connecting part 230 at the front vehicle body 110 will also have this tendency to move. However, under this tendency, the second connecting rod 560 will move relative to the second steep slope 232. Since the connection between the second steep slope 232 and the second abutment surface 231 is not smooth, a certain degree of jamming can be formed in this direction of movement, so that the two will not be disconnected due to this tendency of movement.

[0061] During disassembly, firstly, the fastening connection of the pin assembly 300 is released, and then the pin assembly 300 is lifted upward. At this time, the pin assembly 300 drives the front vehicle body 110 to move upward with the front wheel as the fulcrum. At this time, the first connecting rod 220 at the front vehicle body 110 slides out along the first arc-shaped surface 570 on the upper wall of the first abutment groove 551. Simultaneously, under this movement trend, the second connecting rod 560 will also form a relative movement trend towards the second sliding surface 233. Because the rear vehicle body 120 mentioned by the second connecting rod 560 will also form a downward movement trend with the rear wheel as the fulcrum, the second connecting rod 560 can also slide out along the second sliding surface 233. Therefore, both connecting units can be released by simply pulling up the pin assembly 300.

[0062] Therefore, the connection component can maintain a stable connection during normal use, and can be easily disassembled by simply operating the pin component 300. The operation is simple and convenient.

[0063] In addition, the front body 110 and the rear body 120 are equipped with matching plugs and sockets for connecting wires, so that the plugs and sockets can be separated during disassembly and connected during installation, thereby enabling a stable power supply to the vehicle body.

[0064] In this embodiment, combined with Figure 3 A positioning frame 240 arranged in a horizontal longitudinal direction is connected between the two front axle fixing plates 210. A square connecting slot is formed in the middle of the positioning frame 240. A bent pin fixing tube 250 is provided at the connecting slot to engage with it. The lower end of the pin fixing tube 250 is fixedly connected to the support tube 260 provided at the front vehicle body 110, and the upper end of the pin fixing tube 250 is vertically connected to the front connecting plate 410.

[0065] Specifically, the positioning bracket 240 can better connect the front connecting plate 410 and the aforementioned pin assembly 300 to the support tube 260 at the front vehicle body 110, thereby providing a stable placement position for the pin assembly 300 and providing the prerequisite for subsequent installation personnel to pull the pin assembly 300 to move the front vehicle body 110.

[0066] In this embodiment, combined with Figure 2 and Figure 4 The seat body 130 is movably connected above the front connecting part; the seat positioning seat 270 is fixedly connected to the lower middle part of the two front axle fixing plates 210, and the seat shaft hole 280 and the positioning pin hole are formed through the two front axle fixing plates 210 in a horizontal longitudinal direction at the position above the first connecting rod 220.

[0067] In this embodiment, a seat support rod 271 is movably connected to the upper end of the seat positioning seat 270, and the lower end of the seat support rod 271 is movably connected to the seat positioning seat 270. The upper end of the seat rod is connected to the seat body 130. A seat support plate 2100 is movably connected inside the seat shaft hole 280. A positioning horizontal tube 430 arranged in a horizontal longitudinal direction is connected between the upper ends of the two seat support plates 2100. A fixed U-shaped seat 440 for fixed connection with the seat body 130 is sleeved on the positioning horizontal tube 430.

[0068] A seat positioning pin 290 arranged in a horizontal longitudinal direction is connected in the positioning pin hole. The seat positioning pin 290 is screwed into the positioning pin hole to be positioned and connected with the seat support plate 2100.

[0069] Specifically, since the pin assembly and connecting assembly in this embodiment are arranged separately, the seat body 130 can be directly installed via the seat positioning pin 290. Furthermore, since the seat body 130 is directly positioned above the front connecting portion, firstly, the seat body 130 can shield the pin assembly 300 to prevent accidental operation; secondly, the stable connection between the connecting assemblies can be understood as a one-way limiting connection. The limiting is only released when the front vehicle body 110 is lifted by the pin assembly 300, allowing upward movement with the front wheels as a fulcrum. Therefore, under normal conditions, when the driver sits on the seat body 130 and presses down on the front vehicle body 110, the connecting assembly remains stable. Simultaneously, the aforementioned pin assembly 300, in conjunction with the connecting assembly, ensures a relatively stable connection between the front vehicle body 110 and the rear vehicle body 120 in both the horizontal and vertical directions.

[0070] It is readily understood that those skilled in the art can combine, split, or reorganize the embodiments provided in this application to obtain other embodiments, all of which do not exceed the protection scope of this application.
