Description

Technical Field

[0001] This utility model belongs to the technical field of mobility scooter controllers, and more specifically, it relates to a quick-release structure for an elderly mobility scooter controller. Background Technology

[0002] As an important means of transportation for the elderly, the stability of elderly mobility scooters and the ease of maintenance directly affect the user experience. The controller, as the core control component of the scooter, is responsible for regulating key functions such as power output and speed adjustment. Existing elderly mobility scooter controllers mainly consist of a mounting base, controller body, internal electronic components, a heat dissipation mechanism, and wiring harnesses. During installation, the mounting base is first fixed to the inside of the scooter frame by welding or bolting. Then, multiple sets of bolts are used to secure the controller body to the upper part of the mounting base, thus completing the overall assembly. The heat dissipation mechanism often uses a finned structure to increase the heat dissipation area and ensure efficient heat dissipation for the controller. The wiring harness uses wire harnesses to electrically connect various sensors, actuators, and other components of the scooter to the internal electronic components of the controller, thereby ensuring stable transmission of control commands for the entire vehicle.

[0003] Existing application number CN202322151053.0 discloses an electric mobility scooter controller, belonging to the field of electric vehicle technology. It aims to solve the problem in existing technologies where water and dust easily seep into the inner side of the frame, corroding the wires, especially those with connectors, which can affect transmission quality. The controller includes a main body, a collection box, a protective enclosure assembly, and heat dissipation fins. One side of the main body is fixedly connected to the collection box, which is fixedly fitted onto the outside of the main body. The protective enclosure assembly is slidably installed inside the collection box. The heat dissipation fins are spaced apart from the collection box and arranged around the outer wall of the main body. One side of the main body has an opening through which multiple connecting wires extending outward from the inside of the main body pass. This electric mobility scooter controller can intercept dust and water seeping into the surface of the connecting wires from around the frame, effectively improving the service life of the connecting wires and ensuring the transmission quality between lines.

[0004] Based on the above, existing controllers for elderly mobility scooters mostly use multiple sets of bolts to fasten the controller body to the mounting base to complete the overall assembly. This assembly method requires turning multiple sets of bolts one by one during disassembly and assembly, making the process cumbersome. During maintenance, it is difficult for maintenance personnel to accurately track the number of times the controller has been disassembled and maintained. This not only affects the accuracy of judging the wear cycle of core components but also hinders targeted troubleshooting of historical faults, easily leading to repeated and ineffective repairs. Furthermore, the lack of clear disassembly and assembly records for traceability may also pose a risk of maintenance personnel unauthorized replacement of controller components. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides a quick-release structure controller for elderly mobility scooters. This addresses the issue that existing controllers typically use multiple sets of bolts to secure the controller body to the mounting base for assembly. This assembly method requires manually rotating multiple sets of bolts during disassembly and assembly, making the process cumbersome. Furthermore, maintenance personnel find it difficult to accurately track the number of times the controller has been disassembled and maintained, which not only affects the accuracy of judging the wear cycle of core components but also hinders targeted troubleshooting of historical faults, easily leading to repeated and ineffective repairs. In addition, the lack of clear disassembly and assembly records poses a risk of maintenance personnel unauthorized replacement of controller components.

[0006] The purpose and function of this utility model's quick-release structure for an elderly mobility scooter controller are achieved through the following specific technical means: A quick-release mechanism controller for an elderly mobility scooter includes a mounting base, a controller body, a transmission frame, a drive knob, an observer, a quick-release assembly, and a marking assembly. The controller body is located on the upper part of the mounting base; the transmission frame is located on the front side of the mounting base; the drive knob is rotatably connected to the front side of the transmission frame; the observer is fixedly mounted on the upper part of the mounting base; the quick-release assembly is located inside the mounting base; and the marking assembly is located inside the observer.

[0007] Furthermore, the quick-release assembly includes: a snap-fit ​​slot and a limiting bracket. Multiple sets of snap-fit ​​slots are provided, and multiple sets of snap-fit ​​slots are opened inside the mounting base. Multiple sets of limiting brackets are provided, and multiple sets of limiting brackets are fixedly installed at the bottom of the controller body. The size and position of the limiting brackets and snap-fit ​​slots are matched.

[0008] Furthermore, the quick-release assembly also includes: a sliding plate and a first lead screw. The sliding plate is fixedly installed on one side of the transmission frame and is slidably connected inside the mounting base. The end of the first lead screw is fixedly installed on the front side of the drive knob and is threadedly connected inside the mounting base. The transmission frame is rotatably connected to the outer side of the end of the first lead screw.

[0009] Furthermore, the quick-release assembly also includes: an arc-shaped through groove and a limiting arc groove. Multiple sets of the arc-shaped through groove are provided, and multiple sets of the arc-shaped through groove are formed inside the sliding plate. Multiple sets of the limiting arc groove are provided, and multiple sets of the limiting arc groove are formed inside the sliding plate.

[0010] Furthermore, the marking assembly includes a rotating shaft and a driven gear, wherein the rotating shaft is rotatably connected inside the mounting base; the driven gear is coaxially fixedly connected to the outside of the rotating shaft, and the driven gear is rotatably connected inside the mounting base.

[0011] Furthermore, the marking assembly also includes a drive rack, which is fixedly mounted on one side of the sliding plate.

[0012] Furthermore, the marking assembly also includes: a second lead screw, a marking block, and a one-way limiting mechanism. The second lead screw is rotatably connected to the top of the rotating shaft; the marking block is vertically slidably connected inside the observer, and the marking block is threadedly connected to the outside of the second lead screw; the one-way limiting mechanism is fixedly installed at the middle position between the rotating shaft and the second lead screw.

[0013] Compared with the prior art, the present invention has the following beneficial effects: Firstly, this invention features a quick-release assembly. A drive knob, linked to a first lead screw, moves the transmission frame and sliding plate, switching the positions of the arc-shaped through groove and the limiting arc groove on the sliding plate. During installation, the arc-shaped through groove aligns with the snap-fit ​​groove, facilitating the quick insertion of the limiting frame of the controller body. During tightening, the limiting arc groove moves to the upper part of the snap-fit ​​groove, forming a stable limit. Disassembly is achieved simply by turning the drive knob, eliminating the need to rotate bolts one by one, significantly simplifying the assembly and disassembly process, improving maintenance efficiency, and solving the problem of cumbersome traditional bolt assembly operations.

[0014] Secondly, this invention features a marking component. A sliding plate drives a drive rack, which in turn meshes with a driven gear to rotate the shaft. Utilizing a ratchet and pawl structure of a one-way limiting mechanism, the rotating shaft can only drive the second lead screw in one direction, causing the marking block to rise vertically with each tightening operation. Maintenance personnel can observe the height of the marking block through a transparent viewing device, allowing them to intuitively understand the maintenance frequency. This provides a basis for judging the wear cycle of core components and troubleshooting historical faults, reducing repetitive repairs. Furthermore, traceable maintenance records reduce the risk of unauthorized component replacement.

[0015] This utility model has the advantages of quick disassembly, convenient maintenance, and the ability to record the number of disassembly and assembly operations. Disassembly can be performed simply by turning the drive knob, which greatly improves the efficiency of operation. Moreover, it does not require a complex electrical structure to record the number of disassembly operations, and its structure is simple and low in cost. Attached Figure Description

[0023] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0024] Example 1: As attached Figure 1 To be continued Figure 6 As shown: This utility model provides a quick-release structure controller for elderly mobility scooters, including a mounting base 1, a controller body 2, a transmission frame 3, a drive knob 4, an observer 5, and a quick-release assembly. The controller body 2 is located on the upper part of the mounting base 1; the transmission frame 3 is located on the front side of the mounting base 1; the drive knob 4 is rotatably connected to the front side of the transmission frame 3; the observer 5 is fixedly installed on the upper part of the mounting base 1; and the quick-release assembly is located inside the mounting base 1.

[0025] The quick-release assembly includes: a snap-fit ​​slot 101 and a limit bracket 201. Multiple sets of snap-fit ​​slots 101 are provided and are opened inside the mounting base 1. Multiple sets of limit brackets 201 are provided and are fixedly installed at the bottom of the controller body 2. The size and position of the limit brackets 201 and the snap-fit ​​slots 101 are matched.

[0026] The quick-release assembly also includes: a sliding plate 301 and a first lead screw 401. The sliding plate 301 is fixedly installed on one side of the transmission frame 3 and is slidably connected inside the mounting base 1. The end of the first lead screw 401 is fixedly installed on the front side of the drive knob 4 and is threadedly connected inside the mounting base 1. The transmission frame 3 is rotatably connected to the outer side of the end of the first lead screw 401.

[0027] The quick-release assembly also includes: an arc-shaped through groove 302 and a limiting arc groove 303. Multiple sets of arc-shaped through grooves 302 are provided, and multiple sets of arc-shaped through grooves 302 are opened inside the sliding plate 301. Multiple sets of limiting arc grooves 303 are provided, and multiple sets of limiting arc grooves 303 are opened inside the sliding plate 301.

[0028] The specific usage and function of this embodiment are as follows: Turning the drive knob 4 rotates the first lead screw 401, which rotates within the mounting base 1 via its thread. This movement of the first lead screw 401 moves the transmission frame 3, which in turn moves the sliding plate 301. The sliding plate 301 then moves the arc groove 302 and the limiting arc groove 303. When the controller body 2 needs to be installed, turn the drive knob 4 forward, causing the sliding plate 301 to move the arc groove 302 to a position fully aligned with the locking groove 101. At this point, the locking groove 101 is in a connected state, allowing the limiting frame 201 at the bottom of the controller body 2 to be aligned with and inserted into the locking groove 101. Then, turn the drive knob 4 in the reverse direction, causing the sliding plate 301 to move in the opposite direction until the limiting arc groove 303 moves directly above the locking groove 101, providing a stable limit for the limiting frame 201. This completes the quick locking of the controller body 2 with the mounting base 1. During disassembly, simply turn the drive knob 4 in the forward direction to disengage the limiting arc groove 303 from the limiting position and realign the arc through groove 302 with the snap-fit ​​groove 101, and then the controller body 2 can be removed.

[0029] Example 2: Based on Example 1, such as Figures 1 to 6 As shown, it also includes: a marker component, which is set inside the observer 5.

[0030] The marking assembly includes a rotating shaft 501 and a driven gear 502. The rotating shaft 501 is rotatably connected inside the mounting base 1. The driven gear 502 is coaxially fixedly connected to the outside of the rotating shaft 501 and rotatably connected inside the mounting base 1.

[0031] The marking assembly also includes a drive rack 304, which is fixedly mounted on one side of the sliding plate 301.

[0032] The marking assembly also includes: a second lead screw 503, a marking block 504, and a one-way limiting mechanism 505. The second lead screw 503 is rotatably connected to the top of the rotating shaft 501; the marking block 504 is vertically slidably connected inside the observer 5 and threadedly connected to the outside of the second lead screw 503; the one-way limiting mechanism 505 is fixedly installed at the middle position between the rotating shaft 501 and the second lead screw 503.

[0033] The specific usage and function of this embodiment are as follows: As the sliding plate 301 moves with the transmission frame 3, it synchronously drives the drive rack 304 on one side to move. When the drive rack 304 moves to the position where it meshes with the driven gear 502, it drives the driven gear 502 to rotate, thereby driving the coaxially fixed rotating shaft 501 to rotate synchronously. The rotating shaft 501 and the second lead screw 503 are connected by a one-way limiting mechanism 505. This one-way limiting mechanism 505 adopts a ratchet and pawl transmission structure, allowing the rotating shaft 501 to drive the second lead screw 503 to rotate only in one direction. During the operation of fastening and snapping the controller body 2, the rotational torque of the rotating shaft 501 can be transmitted to the second lead screw 503 through the one-way limiting mechanism 505, driving the second lead screw 503 to rotate, and then driving the marker block 504 to rise vertically upward along the inside of the observer 5 through the threaded engagement. Since the front side of the observer 5 is made of transparent material, maintenance personnel can visually judge the number of times the controller needs to be disassembled and maintained by observing the lifting height of the marker block 504. When the drive knob 4 is turned in the opposite direction to disassemble the controller body 2, the reverse rotation torque of the rotating shaft 501 cannot be transmitted to the second lead screw 503 through the one-way limit mechanism 505. The marker block 504 will not reset in the reverse direction, but can only be raised with each tightening operation, thereby realizing the recording of the number of maintenance.
