Description

Technical Field

[0001] This utility model belongs to the field of battery technology, and in particular relates to a self-locking anti-detachment battery structure for electric off-road motorcycles. Background Technology

[0002] Existing electric bicycles, electric e-sports vehicles, and other vehicles typically feature a concealed battery design. They have a hollow frame tube, and the battery is installed inside the hollow frame tube. The hollow frame tube has a locking interface, and the battery has a corresponding positioning pin. After the battery is inserted into the hollow frame tube, the positioning pin is locked into the locking interface, so that the battery can be fixed to the hollow frame tube.

[0003] However, the connection stability is poor when using only a single positioning pin and card interface. In some complex road sections, the positioning pin may detach from the card interface, causing the battery to fall off. At the same time, the existing battery is also inconvenient to remove after unlocking.

[0004] In addition, existing batteries usually have an outer cover installed on one side, firstly to protect the battery, and secondly to match the design of the vehicle body to achieve a hidden effect. However, since the vehicle body and battery are basically produced by different manufacturers, and the outer cover is produced together with the battery, the color of the outer cover on the outside of the battery cannot match the color of the vehicle body. Utility Model Content

[0005] The purpose of this utility model is to provide a self-locking anti-detachment battery structure for electric off-road motorcycles to solve the technical problems of unstable battery-body connection, inconvenient battery removal, and inability to unify the color of outer parts and body in existing electric bicycles, electric e-sports vehicles, etc.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a self-locking anti-detachment battery structure for electric off-road motorcycles, including a battery housing, a detachable outer stop on one side of the battery housing, and a limiting part on the top of the battery housing for cooperating with a self-locking mechanism fixed in the frame.

[0007] Preferably, the battery casing has a mounting hole on one side, and the outer retainer has a connecting hole corresponding to the mounting hole. The connecting hole and the mounting hole are connected by a fastener.

[0008] Preferably, a handle is movably provided on the battery housing, and a handle groove for receiving the handle is also provided on the upper surface of the battery housing.

[0009] Preferably, the self-locking mechanism includes a connecting seat mounted on the vehicle frame and a lock disposed on the connecting seat, the lock having a self-locking tongue assembly and a deadbolt tongue assembly.

[0010] Preferably, the upper surface of the limiting part is provided with a first limiting groove and a second limiting groove, and the first limiting groove and the second limiting groove are respectively disposed below the anti-locking tongue group and the self-locking tongue group for their extension and limiting.

[0011] Preferably, the bottom of the connecting seat is provided with an ejection assembly for quickly ejecting the battery housing. The ejection assembly includes a push shaft body and a spring. The connecting seat has an ejection groove for the push shaft body to move. The spring is located between the top wall of the push shaft body and the ejection groove.

[0012] Preferably, the connecting seat has a mounting position for placing the lock, and the mounting position has a through groove for the deadbolt assembly and the self-locking bolt assembly to extend to the bottom of the connecting seat.

[0013] Preferably, an abutment is installed in the second limiting groove. When the limiting part and the self-locking mechanism are fixedly connected, the push shaft body abuts against the abutment and retracts into the push-out groove so that the spring enters the pre-compression state.

[0014] Preferably, the anti-locking tongue assembly includes an anti-locking tongue and a first drive plate integrally formed with the anti-locking tongue. The first drive plate has an anti-locking groove, and a locking rod is provided in the anti-locking groove. The locking rod is connected to a lock cylinder, and a transmission part is connected to the side of the locking rod away from the lock cylinder. The transmission part is provided with a push rod for pushing the self-locking tongue assembly to disengage it from the second limiting groove.

[0015] Preferably, a battery compartment for mounting the battery housing is provided on one side of the vehicle frame. The self-locking mechanism is located on the top of the battery compartment. When the battery housing is installed in the battery compartment, the self-locking tongue group in the self-locking mechanism extends into the second limiting groove. After the lock is locked, the locking tongue group extends into the first limiting groove, and the push-out component is simultaneously put into a pre-pressurized state.

[0016] Compared with the prior art, this utility model has the following advantages through the above technical solution: 1. By setting a detachable outer baffle on one side of the battery casing, the outer baffle can be quickly replaced to unify the color of the outer baffle and the vehicle body. Specifically, the outer baffle is fixed to the battery casing by bolt connection, forming a connection hole for the bolt at the connection point. If the user does not need to disassemble and replace it, a label can be affixed to the connection hole to seal it, thereby increasing the overall aesthetics. If the user needs it, a seal with a pull ring can be set here. When the outer baffle needs to be disassembled, the seal can be removed by pulling the ring to disassemble the outer baffle. Through the above method, different colored outer baffles can be quickly replaced, thereby achieving consistency between the outer baffle and the vehicle body color, solving the technical problem of the inability to unify the color of the outer baffle and the vehicle body in existing electric bicycles, electric e-sports vehicles, etc. In addition, the disassembly and assembly method can also make the color of the outer baffle different from the color of the vehicle body, highlighting personalization.

[0017] 2. By incorporating a self-locking mechanism within the vehicle frame and a limiting part on the battery casing that can connect with the self-locking mechanism, quick installation and removal of the battery casing can be achieved. Specifically, when assembling the battery casing, first place the battery casing on one side of the battery compartment of the vehicle frame, aligning the limiting part at its top with the connecting seat in the self-locking mechanism. Then, push the battery casing into the battery compartment. At this point, the limiting part will first push the self-locking tongue assembly on the connecting seat upwards until the second limiting groove on the limiting part moves to below the self-locking tongue assembly. At this point, the self-locking tongue assembly is affected by the spring force. When the self-locking tongue assembly is pushed into the second limiting groove, the battery casing is fully installed in the battery compartment, and the initial limiting of the battery casing and the frame is also completed. Then, the lock in the self-locking mechanism is locked by controlling the key, so that the locking tongue assembly in the lock extends to the first limiting groove on the limiting part, thus completing the secondary limiting. The double locking method improves the stability of the connection between the frame and the battery casing, and solves the technical problem of unstable connection between the battery and the body in existing electric bicycles, electric e-sports vehicles and other vehicles, which leads to the battery being easy to fall off.

[0018] 3. By setting an ejection assembly inside the mounting base, the ejection assembly consists of a push shaft body and a spring. The push shaft body moves within the ejection groove on the mounting base and is confined within the ejection groove. The spring is used to abut against the push shaft body and the ejection groove. When the battery housing is not installed, the spring is released, and the push shaft body is in an ejected state within the ejection groove. When the battery housing is installed, the abutment at the top of the battery housing pushes the push shaft body back into the ejection groove and compresses the spring to store force. At the same time, the self-locking tongue group falls into the first limiting groove, completing the initial locking and putting the push shaft body in a pre-pressurized state. When unlocking (i.e., the self-locking tongue group exits the first limiting groove), the pressure on the spring is contacted, the spring is released, and the push shaft body is ejected. After the push shaft body is ejected, it abuts against the battery housing, thus applying a pushing force to the battery housing, thereby pushing one end of the battery housing out of the battery compartment, realizing the quick disassembly of the battery housing, making it easier to remove the battery housing, and solving the technical problem of the inconvenience of removing the battery in existing electric bicycles, electric gaming vehicles, and other vehicles.

[0024] like Figure 1-11As shown: A self-locking anti-detachment battery structure for electric off-road motorcycles includes a battery housing 1, a battery body inside the battery housing 1, a detachable outer stop 2 on one side of the battery housing 1, and a limiting part 101 on the top of the battery housing 1 for connecting with a self-locking mechanism 40 fixed in the frame 20. In this embodiment, the limiting part 101 is the top cover of the battery housing 1. The battery housing 1 is composed of an outer shell, a top cover, and a bottom cover, and has a cavity formed inside for accommodating the battery body. The top cover, as the limiting part 101, is used to connect the self-locking mechanism 40 to achieve fixed installation of the battery housing 1, while the bottom cover is used to connect the controller.

[0025] like Figure 1 As shown: A mounting hole 104 is provided on one side of the battery housing 1. In this embodiment, the mounting hole 104 is located on one side of the top cover, i.e., the limiting part 101, to prevent the outer shell surrounding the battery body from being damaged and to increase the service life of the product. The outer retainer 2 is provided with a connecting hole 201 corresponding to the mounting hole 104. The connecting hole 201 and the mounting hole 104 are connected by a fastener. During installation, the connecting hole 201 on the outer retainer 2 is first aligned with the mounting hole 104 on the limiting part 101. An internal thread can be provided in the mounting hole 104 or a nut can be fixed in it. Then, the fastener is passed through the connecting hole 201 and extends into the mounting hole 104, and is fastened to the internal thread or the fixing nut in it by screwing to realize the connection between the outer retainer 2 and the battery housing 1. In this embodiment, the fastener is a fixing bolt. When disassembly is required, the bolt can be unscrewed to remove it from the mounting hole 104, which is very convenient.

[0026] By providing a detachable outer cover 2 on one side of the battery casing 1, the outer cover 2 can be quickly replaced to match the color of the outer cover and the vehicle body. Specifically, the outer cover is fixed to the battery casing 1 with bolts, creating a bolt hole 201 at the connection point. If the user does not need to disassemble or replace it, a label can be affixed to the connection hole 201 to seal it and improve the overall aesthetics. If the user requires it, a pull ring can be provided at this point. When the outer cover needs to be removed, the pull ring can be used to remove the seal and disassemble the outer cover 2. In this way, different colored outer cover 2s can be quickly replaced, thus achieving color consistency between the outer cover 2 and the vehicle body, solving the technical problem of not being able to unify the color of the outer cover and the vehicle body in existing electric bicycles, electric gaming scooters, and other vehicles. In addition, the disassembly and reassembly method also allows the color of the outer cover to be different from the body color, highlighting personalization.

[0027] like Figure 4 as well as Figure 9As shown: A handle 105 is movably provided on the battery housing 1. Both ends of the handle 105 are hinged to the battery housing 1. The upper surface (top cover) of the battery housing 1 is also provided with a handle groove 106 for storing the handle 105. One side of the handle groove 106 is provided with a slot for easily moving the handle 105 stored in the handle groove 106. By setting the handle 105, it is easier to take out and carry the battery when it needs to be charged, which increases the portability of the battery housing 1. At the same time, the design of the foldable handle 105 will not occupy the coverage area of ​​the battery housing 1.

[0028] like Figure 1 as well as Figure 3-8 and Figure 10 As shown: The self-locking mechanism 40 includes a connecting seat 3 installed on the frame 20 and a lock 4 set on the connecting seat 3. The lock 4 is fixedly installed on the connecting seat 3 by a fixed thread connection. The lock 4 has a self-locking tongue assembly 401 and a deadbolt tongue assembly 402. The self-locking tongue assembly 401, through the cooperation of a spring pin, can push the battery housing 1 into the movable groove of the lock 4 during the connection process between the connecting seat 3 and the battery housing 1, and at the same time, the spring is in a pre-compressed state. When the battery housing 1 is installed in place, the self-locking tongue assembly 401 will correspond to the second limiting groove 103. At this time, the spring will be released, so that the locking tongue of the self-locking tongue assembly 401 is engaged in the second limiting groove 103, completing the initial limiting. The overall structure is simple, easy to use, and the locking is completed by pushing the battery housing 1 into the battery compartment 100, which is convenient and convenient.

[0029] By providing a self-locking mechanism 40 within the frame 20 and a limiting part 101 on the battery housing 1 that can cooperate with the self-locking mechanism 40, quick installation and removal of the battery housing 1 can be achieved. Specifically, when assembling the battery housing 1, the battery housing 1 is first placed on one side of the battery compartment 100 of the frame 20, with the limiting part 101 at its top aligning with the connecting seat 3 in the self-locking mechanism 40. Then, the battery housing 1 is pushed into the battery compartment 100. At this time, the limiting part 101 will first push the self-locking tongue assembly 401 on the connecting seat 3 upwards until the second limiting groove 103 on the limiting part 101 moves to below the self-locking tongue assembly 401. Under the influence of spring force, it is pushed down into the second limiting groove 103. When the self-locking tongue assembly 401 is located in the second limiting groove 103, the battery housing 1 is completely installed in the battery compartment. At the same time, the initial limiting of the battery housing 1 and the frame 20 is completed. Then, the lock 4 in the self-locking mechanism 40 is locked by the key, so that the anti-locking tongue assembly 402 in the lock 4 extends into the first limiting groove 102 on the limiting part 101, thus completing the secondary limiting. The stability of the connection between the frame 20 and the battery housing is improved by the double locking method, which solves the technical problem of unstable connection between the battery and the body in existing electric bicycles, electric e-sports vehicles and other vehicles, which leads to the battery being easy to fall off.

[0030] like Figure 4 , Figure 7 and Figure 9 As shown: The upper surface of the limiting part 101 is provided with a first limiting groove 102 and a second limiting groove 103. The size and depth of the first limiting groove 102 and the second limiting groove 103 are respectively matched with the anti-locking tongue group 402 and the self-locking tongue group 401. The first limiting groove 102 and the second limiting groove 103 are respectively arranged below the anti-locking tongue group 402 and the self-locking tongue group 401 for their extension and limitation. At the same time, pads are installed in the first limiting groove 102 and the second limiting groove 103 respectively. The pad in the second limiting groove 103 is an abutment 107, which is used to push the push-out component 5 to put it in a pre-pressed state.

[0031] like Figure 7 As shown: The bottom of the connecting seat 3 is provided with an ejection assembly 5 for quickly ejecting the battery housing 1. The ejection assembly 5 includes a push shaft body and a spring. The spring is sleeved on the push shaft body. The connecting seat 3 is provided with an ejection groove 301 for the push shaft body to move. The spring is located between the push shaft body and the top wall of the ejection groove 301.

[0032] like Figure 8 As shown: The connecting seat 3 has a mounting position for placing the lock 4. The mounting position is provided with a through groove 302 for the deadbolt assembly 402 and the deadbolt assembly 401 to extend to the bottom of the connecting seat 3. The through groove 302 has two corresponding to the first limiting groove 102 and the second limiting groove 103 respectively.

[0033] like Figure 4 , Figure 7 and Figure 9 As shown: An abutment 107 is installed in the second limiting groove 103. When the limiting part 101 and the self-locking mechanism 40 are fixedly connected, the push shaft body abuts against the abutment 107 and retracts into the push-out groove 301 so that the spring enters the pre-compression state.

[0034] An ejection assembly 5 is provided inside the mounting base 3. The ejection assembly 5 consists of a push shaft body and a spring. The push shaft body moves within the ejection groove 301 on the mounting base 3 and is confined within the ejection groove 301 (interference fit). The spring abuts against the push shaft body and the ejection groove 301. When the battery housing 1 is not installed, the spring is released, and the push shaft body is in an ejected state within the ejection groove. When the battery housing 1 is installed, the abutment 107 at the top of the battery housing 1 pushes the push shaft body back into the ejection groove 301 and compresses the spring to store force. At the same time, the self-locking tongue assembly 401 falls into the first... Within the limiting groove 102, initial locking is completed, placing the push shaft body in a pre-pressurized state. When unlocking (i.e., the self-locking tongue group 401 exits the first limiting groove 102), the pressure applied to the spring is contacted, the spring is released, and the push shaft body is pushed out. After the push shaft body is pushed out, it abuts against the battery housing 1, thus applying a pushing force to the battery housing 1, thereby pushing one end of the battery housing 1 out of the battery compartment 100, realizing the quick disassembly of the battery housing 1, making it easier to remove the battery housing 1, and solving the technical problem that it is inconvenient to remove the battery in existing electric bicycles, electric gaming vehicles, and other vehicles.

[0035] like Figure 11 As shown: The deadbolt assembly 402 includes a deadbolt and a first drive plate integrally formed with the deadbolt. The first drive plate has a deadbolt groove 403, within which a locking rod 404 is located. The locking rod 404 is connected to a lock cylinder 405. A transmission part 406 is connected to the side of the locking rod 404 away from the lock cylinder 405. The transmission part 406 has a push rod 407 for pushing the deadbolt assembly 401 to disengage it from the second limiting groove 103. In use, by inserting a key into the lock cylinder 405, when unlocking is required, the key controls the lock cylinder 405 to rotate clockwise, and the lock cylinder 405 drives the locking rod 404 to move synchronously. Afterwards, the locking rod 404... 4. The transmission unit 406 is rotated, causing the push rod 407 on the transmission unit 406 to push the drive block of the self-locking tongue assembly upward. Since the drive block of the self-locking tongue assembly and the push rod 407 are in contact, the drive block is pushed upward, thereby causing the lock tongue located below the drive block to disengage from the second limiting groove 103 to complete the unlocking. When it is necessary to lock, simply turn the key in the opposite direction, which causes the lock cylinder 405 to rotate counterclockwise and simultaneously drives the lock rod 404 to rotate. This causes the lock rod 404 to move in the anti-locking groove 403 on the first drive plate and drive the first drive plate to move downward, causing the lock tongue in the anti-locking tongue assembly 402 to engage in the second limiting groove 103, thus completing the anti-locking process.

[0036] like Figure 1-2As shown: A battery compartment 100 for installing the battery housing 1 is provided on one side of the frame 20. The battery compartment 100 includes a mounting position for the battery housing 1 and a mounting position for the controller, and the two are connected. At the same time, the battery compartment 100 is arranged at an angle on one side of the frame 20, so when taking out or putting in the battery housing 1, it is not necessary to enter from the bottom, but can be directly inserted from the side, which is very convenient. The self-locking mechanism 40 is located at the top of the battery compartment 100. When the battery housing 1 is installed in the battery compartment 100, the self-locking tongue group 401 in the self-locking mechanism 40 extends into the second limiting groove 103. After the control lock 4 is locked, the locking tongue group 402 extends into the first limiting groove 102, and at the same time, the push-out component 5 is in a pre-pressed state.
