Description

Technical Field

[0001] This application relates to the technical field of electric wheelchairs, and particularly to a battery box installation mechanism for an electric wheelchair. Background Art

[0002] Electric wheelchairs provide great convenience for people with limited mobility, enabling them to carry out daily activities more independently. As one of the core components of an electric wheelchair, the battery not only needs to provide stable power output but also must be easy to replace and maintain to ensure user safety and long-term use of the device.

[0003] Based on this, there is an electric wheelchair proposed in the publication number CN219814524U. Although the battery box is set on the side of the electric wheelchair and can be disassembled and assembled on the electric wheelchair, since the switch is embedded in the battery box and the battery box needs to be observed visually to achieve quick disassembly and assembly, and the battery box is obliquely set, the hand needs to apply force obliquely backward, so the human body needs to tilt obliquely backward when applying force with the hand, and it requires visual observation to achieve quick disassembly and assembly.

[0004] The above content is only used to assist in understanding the technical solution of this application and does not represent an admission that the above content is the closest prior art to this application. Summary of the Invention

[0005] Based on this, this application provides a battery box installation mechanism for an electric wheelchair to solve one of the above technical problems.

[0006] The technical solution adopted by this application to solve its technical problems includes: a wheelchair frame; a fixing plate, both ends of which are installed on the wheelchair frame, and a locking plate and a lower abutting plate are formed on one side of the fixing plate; a battery box, the bottom end of which abuts against the lower abutting plate, a support block is installed at the top end of the battery box, a locking block is rotatably arranged on the support block, the locking block and the support block are connected by a rotating shaft, and a torsion spring is sleeved on the rotating shaft; a control assembly, installed on the other side of the fixing plate where the battery box is arranged, for controlling the electric wheelchair.

[0007] In some embodiments, a connection groove is formed on the locking plate, and a part of the locking block enters the connection groove in the locked state.

[0008] In some embodiments, several first extension parts are formed at both ends in the width direction of the fixing plate for fixing the control assembly on the fixing plate.

[0009] In some embodiments, a second extension part is further formed on one side of the fixing plate, a connection plug is arranged on the second extension part, and a connection socket matching with the connection plug is formed on the battery box.

[0010] In some embodiments, the support block is integrally L-shaped, with a receiving groove formed thereon, and the torsion spring is configured to apply a force that always rotates the locking block towards the receiving groove.

[0011] In some embodiments, the locking block is integrally Z-shaped, and one end thereof that cooperates with the receiving groove is integrally provided with an inclined surface and additionally extends with a part of a barb.

[0012] In some embodiments, a switch button and a power indicator are provided on the battery box.

[0013] In some embodiments, a charging base is installed on the battery box, and a charging cover is rotatably provided on the charging base.

[0014] In some embodiments, two plug-in plates and a butting groove are formed at the bottom end of the battery box. When the battery box is plugged into the wheelchair frame, the plug-in plates are located on both sides of the fixing plate, and the lower butt plate cooperates with the butting groove.

[0015] The beneficial effect of the present application is that since the battery box is disposed in a forward direction and the switch is provided at the upper end of the battery box, the hand only needs to apply a downward force to remove the battery box. When the battery box is installed, the plug-in plates and the lower butt plate can play a positioning role, and the inclined surface of the locking block causes the locking block to rise along the upper locking plate when the battery box is installed. When it reaches the connection groove, it will automatically fall under the action of the torsion spring, effectively improving the convenience of the battery box. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0022] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the fact that those of ordinary skill in the art can implement them.

[0023] In the embodiments of the present application, please refer to Figures 1-3 As shown, the present application provides a mounting mechanism for the battery box 3 of an electric wheelchair, mainly including: a wheelchair frame 1; a fixed plate 2, both ends of which are installed on the wheelchair frame 1, and an upper locking plate 21 and a lower abutting plate 22 are formed on one side of the fixed plate 2; a battery box 3, the bottom end of which abuts against the lower abutting plate 22, a support block 31 is installed at the top end of the battery box 3, a lock block 32 is rotatably arranged on the support block 31, the lock block 32 is connected to the support block 31 through a rotating shaft 33, and a torsion spring 331 is sleeved on the rotating shaft 33; a control assembly 4, which is installed on the other side of the fixed plate 2 where the battery box 3 is arranged, and is used to control the electric wheelchair.

[0024] Specifically, when it is necessary to disassemble the battery box 3, only need to press one end of the lock block 32 with a finger and rotate it outward, and the lock block 32 will disengage from the connecting groove 211 of the upper locking plate 21, and the battery box 3 can be taken out smoothly. When it is necessary to install the battery box 3, the plugging plate 38 and the abutting groove 39 play a positioning role, and the lock block 32 will slide upward along the upper locking plate 21 and then enter the connecting groove 211 to complete the installation.

[0025] Next, some preferred / improved embodiments based on the above embodiments will be further elaborated. Any one or a combination of multiple of the following embodiments can be selected.

[0026] Specifically, a connection groove 211 is formed on the locking plate 21. In the locked state, a part of the lock block 32 enters the connection groove 211. This setting makes it impossible to normally remove the battery box 3 in the locked state.

[0027] Referring to Figure 2 As shown, in order to install the control assembly 4 on the fixed plate 2 without random shaking, several first extension parts 23 are formed at both ends of the fixed plate 2 in the width direction to fix the control assembly 4 on the fixed plate 2.

[0028] Specifically, a second extension part 24 is further formed on one side of the fixed plate 2. A connection plug 25 is arranged on the second extension part 24. A connection socket 34 matching the connection plug 25 is formed on the battery box 3. With this setting, when the battery box 3 needs to be installed on the fixed plate 2, the connection plug will naturally cooperate with the connection socket during the installation process of the battery box 3.

[0029] Preferably, since the lock block 32 abuts against the support block 31 under the action of the torsion spring 331, the lock block 32 is not parallel to the support block 31, resulting in a poor fixing effect of the lock block 32. Therefore, the support block 31 is integrally L-shaped, and a receiving groove is formed thereon. The torsion spring 331 is used to apply a force that always rotates the lock block 32 towards the receiving groove.

[0030] Preferably, in order to strengthen the fixing effect of the lock block 32 on the battery box 3 and make the installation of the battery box 3 simpler, the lock block 32 is integrally Z-shaped. One end thereof cooperating with the receiving groove is integrally provided with an inclined surface and extends out an additional part of a barb 321.

[0031] Preferably, a switch button 35 and a power indicator light 36 are arranged on the battery box 3. With this setting, it is convenient to optimize the user experience.

[0032] Referring to Figure 2 As shown, a charging seat 37 is installed on the battery box 3. A charging cover 371 is rotatably arranged on the charging seat 37. With this setting, the charging cover 371 can effectively protect the internal parts of the charging seat 37 and is convenient for charging.

[0033] Referring to Figure 1 As shown, two plug-in plates 38 and a butting groove 39 are formed at the bottom end of the battery box 3. When the battery box 3 is plugged into the wheelchair frame 1, the plug-in plates 38 are located on both sides of the fixed plate 2, and the lower butt plate 22 cooperates with the butting groove 39. With this setting, the butting groove 39 and the plug-in plates 38 can play a role in positioning and installing during the installation of the battery box 3.
