[0033] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention; obviously, the described embodiments are only a part of the embodiments of the implementation mode of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0034] Referring to the accompanying drawings, in the embodiment of this implementation mode, the power supply device of a wheelchair or a mobility scooter includes a bearing frame 1 and a power supply body 2. Among them, the bearing frame 1 is arranged on the vehicle frame, and the bearing frame 1 is arranged on the vehicle frame of the wheelchair or the mobility scooter for installing and carrying the power supply body 2. The power supply body 2 contains a battery, a housing, etc.

[0035] Among them, a first power supply connection and communication component 3 is arranged on the bearing frame 1, and the first power supply connection and communication component 3 is configured at the front part of the bearing frame 1; a second power supply connection and communication component 4 is arranged on the power supply body 2, and the second power supply connection and communication component 4 is configured at the front part of the power supply body 2; the first power supply connection and communication component 3 and the second power supply connection and communication component 4 are correspondingly matched. When the power supply body 2 is installed on the bearing frame 1, the power supply body 2 will be connected through the first power supply connection and communication component 3 and the second power supply connection and communication component 4 to transmit power. The first power supply connection and communication component 3 on the bearing frame 1 will be connected to electrical equipment (such as a motor, etc.) on the vehicle.

[0036] Among them, a connecting slider 5 is arranged on the power supply body 2, and a connecting chute 6 is arranged on the bearing frame 1. The connecting chute 6 and the connecting slider 5 are correspondingly matched, so that when the power supply body 2 is installed on the bearing frame 1, the connecting slider 5 can slide and cooperate in the connecting chute 6 for connection.

[0037] Among them, the connecting slide groove 6 includes a slider loading port 7, and the slider loading port 7 is for the connecting slider 5 to be installed and placed, and the front end of the slider loading port 7 is connected to the first clamping portion 8. The front part of the connecting slider 5 is provided with a second clamping portion 9, and the first clamping portion 8 is clamped and matched with the second clamping portion 9, and the second clamping portion 9 is fixedly connected with the first clamping portion 8 by clamping and matching. The first clamping portion 8 and the second clamping portion 9 are located at the front and are clamped together. After the connecting slider 5 is installed and placed in the slider loading port 7, when the connecting slider 5 slides forward, the second clamping portion 9 can be clamped with the first clamping portion 8; when the connecting slider 5 slides backward, the second clamping portion 9 and the first clamping portion 8 can be disengaged and released from the clamping state, and the connecting slider 5 can be taken out from the slider loading port 7.

[0038] In addition, a locking groove 10 is provided on the carrier 1, and a locking component 11 is provided on the power supply body 2. The locking component 11 is a locking component 11 extended by a spring (located in the shell of the power supply body, not shown in the figure). The locking component 11 can be extended (extended toward the bottom of the power supply body 2 in the figure) through the spring. The locking component 11 corresponds to the locking groove 10. The locking component 11 is inserted into the locking groove 10 to lock in place, so that the connecting slider 5 slides forward in the connecting slide groove 6 to lock the relative position, thereby preventing the power supply body 2 from shifting on the carrier 1.

[0039] When in use, place the power supply body 2 on the carrier 1, let the connecting slider 5 correspond to the connecting slide groove 6, so that the connecting slider 5 can be installed and placed in the slider loading port 7 of the connecting slide groove 6, and then push the power supply body 2 forward so that the connecting slider 5 can slide forward in the connecting slide groove 6, let the first clamping part 8 and the second clamping part 9 cooperate to clamp and fix, let the power connection component 1 3 and the power connection component 2 4 connect and energize, and when sliding forward to the position, the locking component 11 will be inserted into the locking groove 10 to cooperate to lock and lock the relative position , the power supply body 2 is assembled on the carrier 1, and the operation is convenient. The position of the power supply body 2 after being assembled on the carrier 1 is relatively stable and not easy to shift. When disassembly is required, only the locking component 11 is separated from the locking groove 10, and the power supply body 2 can be moved back and out, so that the power connection component 2 4 and the power connection component 1 3 can be disengaged and separated, and the second clamping part 9 and the first clamping part 8 can also be disengaged and released. The connecting slider 5 can be taken out from the slider loading port 7, and the power supply body 2 can be separated and removed from the carrier 1. In the power supply device of the wheelchair or scooter, the power supply body 2 and the carrier 1 are easy to disassemble and assemble, and convenient to use.

[0040] The following optimization or further explanation may be performed based on the above embodiments.

[0041] For example, the connecting slider 5 is located on the lower side of the power supply body 2. The upper side of the carrier 1 is the installation and placement position of the power supply body 2. The carrier 1 includes a carrier plate 13, a positioning locking groove 10, and a connecting chute 6 located on the carrier plate 13. The power supply body 2 can be stably supported by the carrier 1 (its carrier plate 13). During the disassembly and assembly process, the weight of the entire power supply body 2 can be supported by the carrier 1 and slid, which is convenient for disassembly and assembly and makes it easier.

[0042] In addition to the carrier plate 13, the carrier 1 can also be additionally provided with a power supply positioning side stop 14, which increases convenience and enables faster assembly. For example, the carrier 1 further includes a power supply positioning side stop 14. The power supply positioning side stop 14 is arranged on the left side, right side, and front side of the carrier plate 13. Through the power supply positioning side stop 14, the power supply body 2 can be quickly and conveniently positioned, that is, the connecting slider 5 on the power supply body 2 is quickly aligned with the slider insertion port 7 of the connecting chute 6, and the rear side position allows the power supply body 2 to enter and exit. Among them, the power supply positioning side stop 14 can be directly connected to the carrier plate 13, which is convenient for the entire carrier 1 to be installed on the frame of a wheelchair or a mobility scooter. The inner sides of the power supply positioning side stops 14 are respectively provided with positioning guiding parts 15, and the positioning guiding parts 15 cooperate to guide the positioning of the power supply body 2. For example, the positioning guiding parts 15 adopt positioning guiding surfaces (such as guiding curved surfaces or guiding arc surfaces, etc.). The inner sides of the power supply positioning side stops 14 can also be provided with reinforcing ribs 16, and the positioning guiding parts 15 can be arranged on the reinforcing ribs 16, which not only plays a role in strengthening the structure but also can play a role in positioning and guiding, and the structure is more optimized. The carrier 1 is arranged on the frame, for example, at a position below the seat cushion of the frame.

[0043] Among them, the positioning locking groove 10 is arranged at the tail of the carrier 1, and the positioning locking component 11 is arranged at the tail of the power supply body 2, which is convenient for unlocking operations. The positioning locking component 11 is also equipped with an unlocking pressing component 17. By pressing the unlocking pressing component 17, the elastic force of the spring can be overcome, and the positioning locking component 11 can be retracted to disengage from the positioning locking groove 10, and with the cooperation of unlocking, the power supply body 2 can be retracted backward and removed. Among them, the unlocking pressing component 17 and the spring cooperate correspondingly to overcome the elastic force of the spring and cooperate with unlocking.

[0044] For example, the unlocking pressing member 17 is connected to a spring (such as a compression spring, etc.). The unlocking pressing member 17 can cooperate with the spring to overcome the elastic force of the spring for unlocking (such as causing the compression spring to retract). The unlocking pressing member 17 is connected to the in-place locking member 11. Pressing the unlocking pressing member 17 can drive the in-place locking member 11 to retract and unlock from the extended state. The in-place locking member 11 is arranged on the lower side of the power supply body 2, and the unlocking pressing member 17 is arranged on the lower side of the power supply body 2. The same-side arrangement facilitates connection and unlocking operations. The in-place locking member 11 is arranged relatively downward on the power supply body 2, and the unlocking pressing member 17 is arranged relatively downward on the power supply body 2. The power supply body 2 is also provided with an extension limiting portion (such as a corresponding blocking and limiting portion is provided on the housing of the power supply body 2). The extension limiting portion is used for the in-place locking member 11 to perform extension limiting cooperation (under the action of the spring), so that the extension distance of the in-place locking member 11 can be limited. The unlocking pressing member 17 is located at the rear side of the in-place locking member 11. A tail grasping and unlocking operation space of the power supply body 2 is left at the rear side of the carrier 1. When the power supply body 2 is installed on the carrier 1, the unlocking pressing member 17 at the tail of the power supply body 2 is not supported and blocked by the carrier 1 and is suspended at the rear side of the carrier 1. During operation, the carrier 1 does not affect the grasping of the power supply body 2 and does not affect the pressing and unlocking of the unlocking pressing member 17, which is more convenient.

[0045] In addition, a retraction guiding surface 19 (such as an inclined surface or a curved surface, etc.) is provided on the front side of the in-place locking member 11. When the power supply body 2 slides forward, the in-place locking member 11 can retract under the action of the retraction guiding surface 19 until the in-place locking member 11 moves to the in-place locking groove 10 and then extends. The in-place locking member 11 is inserted into the in-place locking groove 10. A locking anti-retreat surface 20 is provided on the rear side of the in-place locking member 11. After the in-place locking member 11 is inserted into the in-place locking groove 10, the locking anti-retreat surface 20 can prevent the in-place locking member 11 from disengaging and retreating from the in-place locking groove 10 before unlocking.

[0046] It can also be optimized. A grasping portion 21 is further provided on the pressing surface of the unlocking pressing member 17 (such as a pressing block). The pressing surface is arranged relatively downward with respect to the power supply body 2. The grasping portion 21 is convenient for the user to grasp and facilitates the picking up and placing of the power supply body 2. In addition, grasping depressions (such as being adapted to the shape of fingers, etc.) are provided on the grasping portion 21, making grasping more convenient and comfortable. The grasping portion 21 and the tail of the power supply body 2 form a grasping area, which is convenient for the operator to grasp. The tail (grasping area) of the power supply body 2 can be grasped without affecting other structures, such as single-handed grasping.

[0047] For example, the first clamping portion 8 includes a clamping flat head, such as a protruding portion at the edge of the connecting groove; the second clamping portion 9 includes a clamping notch, which is arranged forward relative to the power supply body 2, that is, the entrance of the clamping notch faces forward, so that when the power supply body 2 moves forward, the clamping notch can smoothly engage with the clamping flat head. In addition, the clamping notch also has a clamping side wall 22 (such as a clamping arc or curved or inclined side wall), which can be clamped forward when the power supply body 2 moves forward.

[0048] For another example, a lifting and slot-leaving guide surface 23 (such as a curved surface or an inclined surface) is provided at the rear portion of the connecting slider 5. The lifting and slot-leaving guide surface 23 is arranged on the lower side of the connecting slider 5 so that when the power supply body 2 slides backward, the lifting and slot-leaving guide surface 23 can act on the rear edge position of the connecting slot 6 (that is, the rear edge of the connecting slot 6 is the lifting edge 24). The lifting and slot-leaving guide surface 23 cooperates with the rear edge of the connecting slot 6, so that the connecting slider 5 can be detached from the connecting slot 6 during the backward sliding process of the power supply body 2.

[0049] One of the power connection component 1 3 and the power connection component 2 4 includes a plug, and the other includes a socket; the plug and the socket are plugged in and matched with each other, when the power body 2 moves forward, the plug is inserted into the socket and connected; when the power body 2 moves backward, the plug is pulled out of the socket and separated. Assembly can be completed by putting and pushing, and disassembly can be completed by pulling and taking.
