A battery box bracket includes a bracket structure, an elastic docking device disposed in the first mounting part, positioning devices disposed at the four corners near the elastic docking device, and locking devices disposed on both sides of the positioning device. This patent can adjust the force on the connector, making the connector less prone to mechanical damage and improving the service life of the connector; it can withstand a 3T overturning moment, ensuring high safety; and it achieves a weight reduction effect. However, this patent does not address how to install and fix the connector or how to determine if it is properly fixed.

[0004] Therefore, how to securely fix the battery box and bracket, and how to determine if they are properly secured, are urgent problems that need to be solved. Summary of the Invention

[0005] The purpose of this invention is to overcome the defects of the prior art by providing a disassembly and assembly bracket for a subway train battery box and its alignment detection method.

[0006] The objective of this invention can be achieved through the following technical solutions: According to one aspect of the present invention, a mounting bracket for a subway train battery box is provided, comprising a control unit, an alarm unit, a main frame, a locking unit, and a sensor unit. The control unit, alarm unit, and locking unit are all mounted on the main frame, and the sensor unit is mounted on the locking unit. The control unit is communicatively connected to the alarm unit and the sensor unit, respectively.

[0007] As a preferred technical solution, the locking unit includes a pin, a pressing block, an ejection mechanism, a locking cabinet, and a locking mechanism. The pin is installed in the locking cabinet through the ejection mechanism and the locking mechanism, and the pressing block passes through the locking cabinet and the pin and is connected to the locking mechanism.

[0008] As a preferred technical solution, the locking mechanism includes a pressing block spring and a locking block. The locking block is mounted on the locking cabinet via the pressing block spring, and the pressing block and the locking block are in contact.

[0009] As a preferred technical solution, the pin includes a receiving cavity that accommodates a locking block and a compressed pressing block spring.

[0010] As a preferred technical solution, the ejection mechanism includes a pin spring, and the bottom of the pin is mounted on the locking cabinet via the pin spring.

[0011] As a preferred technical solution, the moving directions of the ejection mechanism and the locking mechanism are perpendicular to each other.

[0012] As a preferred technical solution, the sensor unit includes a pressure sensor, which is disposed on the end face of the pin, and the pressure sensor is communicatively connected to the control unit.

[0013] As a preferred technical solution, the locking unit is installed on the side of the main frame.

[0014] As a preferred technical solution, the alarm unit includes a buzzer, which is communicatively connected to the control unit.

[0015] According to another aspect of the present invention, an alignment detection method is provided for a disassembly bracket for a subway train battery box as described above, the method comprising: S1. After aligning the battery box with the locking unit, activate the locking unit; S2. The locking unit is inserted into the battery box. If the sensor unit contacts the battery box, a contact signal is emitted. S3. If the control unit receives a contact signal, it will trigger the alarm unit.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. The locking unit of the present invention can achieve precise alignment and rigid locking of the battery box and bracket, avoid displacement and shaking during movement, and ensure accurate assembly position; the sensor unit monitors in real time whether the locking action is in place, eliminating the need for manual judgment based on experience, thus preventing safety hazards such as false locking and incomplete locking; the control unit automatically triggers the alarm unit according to the sensor signal to remind when locking is not completed, thus preventing accidents caused by movement without locking.

[0017] 2. This invention uses a pressure sensor to check whether the pin is inserted correctly. The pressure sensor is located on the end face of the pin. When correctly inserted, the end face of the pin perfectly matches the socket of the battery box, that is, the end face of the pin does not contact any surface, and the pressure sensor will not be triggered. If it is not installed correctly, the pressure sensor will contact other structures and generate a pressure signal. The control unit will know that it is not properly fitted after receiving the signal.

[0018] 3. The present invention is provided with a locking mechanism consisting of a pressure block spring and a locking block. By pressing the pressure block, the locking block is pushed to compress the pressure block spring, thereby unlocking the pin and allowing it to be pushed out by the ejection mechanism to complete the fixing of the battery box.

[0019] 4. The present invention provides a receiving cavity, which facilitates the smooth ejection of the pin under the action of the ejection mechanism after the locking block is compressed.

[0020] 5. The present invention is provided with an ejection mechanism consisting of a pin and a spring, which ejects the pin under the action of the pin and spring after the pin is unlocked.

[0021] 6. This invention forms a complete control process from alignment and locking insertion to signal detection and alarm prompts, eliminating the need for manual observation and judgment. It achieves intelligent management and control by forming a closed loop from mechanical locking to status perception and alarm prompts, reducing manual intervention, minimizing human error, and improving the automation and safety of disassembly and assembly operations.

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0024] Example 1 like Figure 1 As shown, a mounting bracket for a subway train battery box includes a control unit, an alarm unit, a main frame 1, a locking unit, and a sensor unit. The control unit, alarm unit, and locking unit are all mounted on the main frame 1, and the sensor unit is mounted on the locking unit. The control unit is communicatively connected to the alarm unit and the sensor unit.

[0025] In this embodiment, a battery mounting and dismounting bracket with small size and weight was designed and manufactured. It is used in conjunction with the hydraulic lifting vehicle 12 or hydraulic pallet truck at the work site. It can be used in a small space, which enhances the adaptability of the tooling. It can help maintenance personnel complete the work quickly in a relatively limited work space, reduce the labor intensity of maintenance personnel, and improve work efficiency.

[0026] The battery box 11 has a socket on its body. After aligning the socket with the locking unit, the locking unit is inserted into the socket to fix the battery box 11 to the bracket.

[0027] The main frame 1 is also equipped with a shovel foot 2 and a limiting foot plate 3, which are used by other equipment to adjust the position of the main frame 1. During the disassembly of the battery box 11, this bracket is placed on the hydraulic lifting trolley 12. The shovel foot 2 and the limiting foot plate 3 can effectively limit the placement position and improve safety.

[0028] like Figure 2 and Figure 3 As shown, the locking unit includes a pin 4, a pressing block 6, an ejection mechanism, a locking cabinet, and a locking mechanism. The pin 4 is installed in the locking cabinet through the ejection mechanism and the locking mechanism. The pressing block 6 passes through the locking cabinet and the pin 4 and is connected to the locking mechanism.

[0029] The locking mechanism includes a pressing block spring 9 and a locking block 13. The locking block 13 is mounted on the locking cabinet by the pressing block spring 9, and the pressing block 6 and the locking block 13 are in contact.

[0030] The pin 4 includes a receiving cavity 14, which accommodates the locking block 13 and the compressed pressing block spring 9.

[0031] The ejection mechanism includes a pin spring 10, and the bottom of the pin 4 is mounted on the locking cabinet via the pin spring 20.

[0032] The ejection mechanism and the locking mechanism move in directions perpendicular to each other.

[0033] The sensor unit includes a pressure sensor, which is disposed on the end face of the pin 4, and the pressure sensor is communicatively connected to the control unit.

[0034] In this embodiment, the locking cabinet includes a stop body 5, a stop rear plate 7, and a stop bottom plate 8. The stop body 5 and the stop bottom plate 8 are both installed on the stop rear plate 7. The stop bottom plate 8 is located at the bottom of the stop body 5. The stop body 5, the stop rear plate 7, and the stop bottom plate 8 form the movable chamber of the pin 4.

[0035] An opening is provided on the stop body 5, and a through hole is also provided on the corresponding pin 4. The locking block 13 is connected to the stop rear plate 7 through the pressing block spring 9. The locking block 13 and the pressing block 6 are in contact in the through hole of the pin 4. Pressing the pressing block 6 pushes the locking block 13 and compresses the pressing block spring 9, thus unlocking the pin 4. Then, under the action of the pin spring 10, the pin 4 is pushed out, and the extended pin 4 cooperates with the socket on the battery box 11 to complete the fixation. In this process, a receiving cavity 14 is also provided on the pin 4, which is close to the locking block 13 and the pressing block spring 9. When the pressing block spring 9 is compressed, the locking block 13 approaches the stop rear plate 7. At this time, the pin 4 moves outward. In order to avoid the locking block 13 causing obstruction, the receiving cavity 14 accommodates the locking block 13 and the pressing block spring 9 during the movement of the pin 4.

[0036] like Figure 4 As shown, the hydraulic lifting trolley 12 and the bracket for disassembling and assembling the battery box are pushed together to the bottom of the battery box 11. Initially, the pin 4 is in the retracted state. As the hydraulic lifting trolley 12 is slowly raised, the position of the bracket for disassembling and assembling the battery box is adjusted to align it. When the hydraulic lifting trolley 12 is raised to the correct position, the pressing block 6 is pressed. At this time, the pin 4 pops upward under the action of the pin spring 10, and the battery box 11 is then restrained on the bracket. At this time, the fixing screws of the battery box 11 can be removed so that it can fall on the bracket. When the pin 4 is not needed, the pin 4 is pressed directly. During the descent of the pin 4, the pressing block 6 will be locked into the pin 4 under the action of the pressing block spring 9, so the pin 4 cannot extend.

[0037] The pressing block 6 can be divided into a pressing part and a connecting part, which are in sequential contact with the locking block 13. When the pin 4 is locked, the connecting part spans the stop body 5 and the pin 4 to lock. When the pin 4 is unlocked, the connecting part is completely located in the pin 4 and pushes the locking block 13 to be flush with the receiving cavity 14. The pressing part does not extend into the pin 4, so that the connecting part moves with the pin 4. If it is to be relocked later, under the action of the pressing block spring 9, the locking block 13 and the connecting part are pushed, so that the connecting part spans the stop body 5 and the pin 4 again, and pushes the pressing part to reset, thus completing the locking.

[0038] The pin 4 needs to extend and lock, which is achieved using two springs. Therefore, the axes of the two springs must be perpendicular to each other, so that the moving directions of the ejection mechanism and the locking mechanism are perpendicular to each other, thus completing the extension and locking simultaneously.

[0039] A pressure sensor is installed on the top end face of the pin 4. To achieve the locking unit's snap-fit, a socket is provided on the battery box 11. After the pin 4 extends, it enters the socket to complete the fixation. The socket and the pin 4 are the same size, that is, when the pin 4 is inserted into the socket, the top end face of the pin 4 will not contact any component, and there will be no pressure to trigger the pressure sensor. If the position is not aligned, during the upward movement of the pin 4, the pressure sensor on its top end face will contact other components, such as the edge of the socket, and thus be detected by the pressure sensor as a contact signal. After receiving the contact signal, the control unit can know that the battery box 11 and the bracket are not aligned and will issue an alarm signal.

[0040] The locking unit is installed on the side of the main frame 1.

[0041] In this embodiment, for ease of operation, the locking unit is installed on the side of the main frame 1, preferably one locking unit on each side, and a pressure sensor is installed on each locking unit.

[0042] The alarm unit includes a buzzer, which is communicatively connected to the control unit.

[0043] In this embodiment, a buzzer is used for alarm, emitting a sharp sound to remind the user.

[0044] This invention simplifies the overall structure of the bracket, reducing its weight and size, making it particularly suitable for use in smaller spaces. It can meet the needs of most working conditions under limited working environments and conditions. The pop-out pin 4 on the fixture effectively limits the displacement of the battery box 11, and the spring and pin can be quickly retracted when not in use, which is convenient and quick. To facilitate compatibility with various tool carts on site, the frame is equipped with feet and limiting structures for easy matching with different tool carts. This fixture can efficiently complete the work, greatly facilitating the operation of on-site personnel and improving work efficiency.

[0045] By using springs and pins to restrict the position of the battery box 11, the installation and removal of the battery box 11 can be made safer. This spring and pin structure is compact and small in size. Through the interaction of two sets of springs, the springs and pins can quickly and easily exert their restrictive effect. This tooling is highly adaptable, easy to operate, and has low maintenance costs. It can improve on-site work efficiency.

[0046] Example 2 A method for aligning and detecting the mounting and dismounting bracket for a subway train battery box, the method comprising: S1. After aligning the battery box with the locking unit, activate the locking unit; S2. The locking unit is inserted into the battery box. If the sensor unit contacts the battery box, a contact signal is emitted. S3. If the control unit receives a contact signal, it will trigger the alarm unit.

[0047] In this embodiment, during use, the locking unit is first aligned with the socket on the battery box, and then the pressing block 6 is pressed to make the pin 4 pop out and lock. If a sensor signal is received during this process, it indicates that the current position is not aligned, and an alarm is triggered by a buzzer.

[0048] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in the present invention, and these modifications or substitutions should all be covered within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
