A quick-disassembly wheelchair

Abstract

This utility model discloses a quick-detachable wheelchair, comprising a front section with an A-axis and a B-axis; a motor section with a motor hook for detachably connecting to the A-axis and B-axis; and a quick-release lever rotatably mounted on the motor section. When in the locked position, the quick-release lever prevents the motor hook from disengaging from the A-axis and B-axis. When the quick-release lever is lifted to the unlocked position, the front section of the wheelchair is allowed to separate from the motor section. Through this structure, the wheelchair is connected to the motor hook via a specific pivot at the front, and mechanically locked using a quick-release lever with a self-resetting spring, achieving a balance between secure connection and convenient disassembly. In daily use, the lever is reliably locked by the spring, preventing accidental separation. When transport is required, the user can quickly disassemble the wheelchair into two main modules (front and rear) simply by pulling the lever by hand.

[0015] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0016] Reference Figure 1-5 This utility model provides a quick-disassembly wheelchair, comprising: a front part 1 of the wheelchair and a motor part 2, which are quickly connected and separated by a detachable connection mechanism. The front part 1 of the wheelchair is provided with an A-axis and a B-axis extending laterally.

[0017] The motor part 2 is provided with a motor hook for detachably connecting with the A-axis and B-axis of the front part 1 of the wheelchair. Specifically, the motor hook includes an upper hook and a lower hook provided on the motor part 2. The upper hook is used to connect with the A-axis and the lower hook is used to connect with the B-axis.

[0018] To enable quick assembly and disassembly, a quick-release lever 3 is provided on the motor part 2. The quick-release lever 3 is rotatably mounted on the motor part 2 via the C-axis and can rotate between the locked and unlocked positions. When the quick-release lever 3 is in the locked position, its structure blocks the opening side of the motor hook, thereby preventing the motor hook from disengaging from the A-axis and B-axis and ensuring reliable connection. When disassembly is required, the quick-release lever 3 is lifted upward and rotated to the unlocked position. At this time, the opening of the motor hook is opened, allowing the A-axis and B-axis of the front part 1 of the wheelchair to disengage from the hook, thereby achieving the separation of the front part 1 of the wheelchair from the motor part 2.

[0019] To ensure safe use and prevent accidental unlocking, a reset spring 8 is provided. One end of the reset spring 8 is connected to the motor part 2, and the other end is connected to the quick-release lever 3. Under the tension of the reset spring 8, the quick-release lever 3 is continuously biased toward the locked position, which has the tendency to automatically lock.

[0020] The core structure of the motor part 2 includes the motor 9 and the motor fixing plate group. The motor fixing plate group consists of the motor fixing plate left 4 and the motor fixing plate right 5, which are respectively fixed on both sides of the motor 9. An anti-detachment hook 6 is rotatably installed between the left and right motor fixing plates through the rotating shaft 7. The anti-detachment hook 6 constitutes the key upper hook part of the motor hook mentioned above. The anti-detachment hook 6 is linked with the quick release lever 3. That is, the action of the quick release lever 3 can control the rotation opening and closing of the anti-detachment hook 6. The specific installation method of the reset spring 8 is: one end of it is fixed through the hole (A in the attached figure) and the corresponding bolt (B in the attached figure) on the motor fixing plate group.

[0021] In addition, the motor part 2 also includes a walking mechanism and a linkage unhooking mechanism, specifically composed of a connecting rod 12, a left hook part 11, a right hook part 13, a left wheel 10, a right wheel 14, and a handle 15. The left wheel 10 is installed on the left hook part 11, and the right wheel 14 is installed on the right hook part 13. The left hook part 11 and the right hook part 13 are respectively connected to the two ends of the connecting rod 12. The handle 15 is installed on the aforementioned anti-detachment hook 6. Through this structure, when the handle 15 is operated, the anti-detachment hook 6 can be driven to move, thereby linking the left hook part 11 and the right hook part 13 through the connecting rod 12 to achieve simultaneous unhooking of the hooks on both sides.

[0022] Specifically, for assembling motor part 2: fix the left motor fixing plate 4 and the right motor fixing plate 5 to both sides of the motor 9 by passing bolts through the corresponding through holes (C, D, E, F shown in the figure). Then, use the rotating shaft 7 to install the anti-detachment hook 6 between the left and right motor fixing plates so that it can rotate around the rotating shaft 7. Next, hang one end of the reset spring 8 at hole A of the motor fixing plate group and fix it with bolts B and other parts, and connect the other end to the quick release pull rod 3.

[0023] Next, assemble the walking and linkage parts: install the left wheel 10 onto the left hook part 11, install the right wheel 14 onto the right hook part 13, then install the left hook part 11 and the right hook part 13 onto both ends of the connecting rod 12 respectively, and finally, install the handle 15 onto the anti-detachment hook 6.

[0024] Working principle: When it is necessary to connect the motor part 2 to the front part 1 of the wheelchair, first put the B shaft of the front part 1 of the wheelchair into the lower hook of the motor part 2, and then press down the front part of the wheelchair so that its A shaft falls into the upper hook formed by the anti-detachment hook 6. At this time, under the action of the return spring 8, the quick release lever 3 is automatically in or can be moved to the locked position, locking the connection. The anti-detachment hook 6 can rotate around the rotating shaft 7, but its rotation is restricted when the quick release lever 3 is locked, which plays a safety role in preventing the A shaft from falling off.

[0025] When separation is required, lift the quick-release lever 3 to the unlock position to lift the front part 1 of the wheelchair upwards, so that the A-axis and B-axis can be disengaged from the upper and lower hooks respectively. Alternatively, the hooks on both sides can be released by operating the handle 15.

[0026] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
