[0003] However, when the battery pack needs maintenance, it may be necessary to disassemble or replace it. The battery pack is rigidly connected to the vehicle body, which makes the installation and disassembly of the battery pack more complicated and the maintenance efficiency lower.

[0010] In one possible implementation, the inner wall of the cavity with the connection opening is at least partially inclined.

[0011] In one possible implementation, multiple guide grooves are formed on the inner wall of the receiving cavity, one end of which is connected to the connection port, and the lock cylinder is correspondingly arranged in the guide groove.

[0012] In one possible implementation, the battery pack further includes: a cell module disposed within the cavity of the housing; a detection unit for detecting the operating condition information of the cell, including temperature and voltage; and the vehicle further includes: a control unit electrically connected to the detection unit and the locking element respectively, to control the operating state of the locking element according to the detection results of the detection unit.

These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0033] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0034] As shown in the background section, in the prior art, the battery pack is connected to the vehicle body by welding or other methods and fixed to the bottom of the vehicle. When the battery pack needs to be inspected, it may be necessary to disassemble or replace the battery pack. The rigid connection between the battery pack and the vehicle body makes the installation and disassembly of the battery pack more complicated and the maintenance efficiency lower.

[0035] To address the aforementioned technical problems, this application provides a vehicle comprising a body and a battery pack. The body includes two mounting beams opposite each other along a first direction. Multiple mounting slots are formed on the mounting beams along a second direction. Each mounting slot has a locking space, and a locking element is disposed within the locking space. The battery pack includes a housing and locking engagement devices. The locking engagement devices are located on opposite sides of the housing along the first direction, each corresponding to a mounting slot. Each locking engagement device includes a connector and a locking cylinder. The connector is inserted into the mounting slot and has a receiving cavity with a circumferentially connected port communicating with the receiving cavity. The locking cylinder is at least partially located within the receiving cavity and is configured to move within the receiving cavity to pass through the connecting port and engage with the locking element, or to retract from the connecting port into the receiving cavity to disengage from the locking element. When the lock cylinder and locking element engage, the locking mechanism locks with the mounting slot, securing the battery pack to the vehicle body. When the lock cylinder and locking element disengage, the locking mechanism releases from the mounting slot, and the battery pack detaches from the vehicle body under its own weight, thus completing the battery pack removal. This method allows for battery pack installation and removal simply by controlling the movement of the locking element within the receiving cavity, improving maintenance efficiency.

[0036] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.

[0037] See Figures 1 to 5As shown, this application embodiment provides a vehicle, including: a body and a battery pack 200, wherein the body includes two mounting beams 100 opposite each other along a first direction, the mounting beams 100 having a plurality of mounting slots 110, the inner wall of the mounting slots 110 having a locking space 111 and a locking member 112 disposed in the locking space 111; the battery pack 200 includes: a housing 210 and a locking engagement device 220; the locking engagement device 220 corresponds one-to-one with the mounting slots 110, and the locking engagement device 220 includes an insert The connector 221 and the lock cylinder 222 are provided. The connector 221 has a receiving cavity 2211. The connector 221 has a plurality of connection ports 2212 that communicate with the receiving cavity 2211 at intervals along the circumference. The lock cylinder 222 is movably disposed in the receiving cavity 2211. The lock cylinder 222 is adapted to extend from the connection port 2212 into the locking space 111 to lock and engage with the locking member 112, or to retract from the locking space 111 through the connection port 2212 into the receiving cavity 2211 to disengage from the locking member 112.

[0038] In the embodiments of this application, Figure 1 The X direction is the first direction, the Y direction is the second direction, and the Z direction is the third direction. Locking devices 220 are located on opposite sides of the housing 210 along the first direction, and the positions of the locking devices 220 and the mounting grooves 110 correspond one-to-one. Both the locking devices 220 and the mounting grooves 110 are spaced apart along the second direction. When installing the battery pack 200, if... Figure 4 As shown, the connector 221 is inserted into the corresponding mounting slot 110. The lock cylinder 222 is moved so that part of the lock cylinder 222 extends from the connector 2212 into the locking space 111 and engages with the locking member 112. The locking member 112 prevents the lock cylinder 222 from moving further. Thus, part of the lock cylinder 222 is located in the receiving cavity 2211, and part is located in the locking space 111, thereby locking the locking engagement device 220 with the mounting slot 110, and thus fixing the battery pack 200 to the vehicle body. When removing the battery pack 200, as follows... Figure 5 As shown, it is only necessary to control the lock cylinder 222 to disengage from the locking member 112, so that the lock cylinder 222 is completely retracted into the receiving cavity 2211 through the connection port 2212. At this time, there is no positional relationship between the locking device 220 and the mounting groove 110. The battery pack 200 falls under its own weight, and the plug 221 slides relative to the mounting groove 110 in a third direction until it is disengaged from the mounting groove 110, thereby removing the battery pack 200.

[0039] The number of locking devices 220 and mounting slots 110 can be set according to factors such as the length of the vehicle body, the weight of the battery pack 200, and the load-bearing capacity of a single locking device 220. This application embodiment does not limit this, as long as the battery pack 200 can be stably fixed to the vehicle body.

[0040] Furthermore, during the maintenance of the battery pack 200, when disassembling the battery pack 200, a support member can be installed below the battery pack 200. After the lock cylinder 222 disengages from the locking member 112, the support member can lift the battery pack 200, allowing it to slowly descend until it is disconnected from the vehicle body. This prevents the battery pack 200 from falling rapidly and damaging it. In the event of a collision or other accident that causes thermal runaway or other malfunctions in the battery pack 200, the lock cylinder 222 can be promptly disengaged from the locking member 112 to allow the battery pack 200 to fall off quickly, preventing it from catching fire and endangering the safety of the vehicle's occupants. This also facilitates fire rescue operations. The specific disassembly method of the battery pack 200 can be adjusted according to the actual application scenario, and this application embodiment does not impose any limitations on this.

[0041] Therefore, the vehicle provided in this application embodiment only needs to control the movement of the lock cylinder 222 within the receiving cavity 2211, allowing the lock cylinder 222 to extend or retract into the receiving cavity 2211, to complete the installation or removal of the battery pack 200. This simplifies operation and improves the efficiency of battery pack 200 maintenance and replacement. The movement of the lock cylinder 222 can be controlled by a power structure within the lock cylinder 222 itself, or by a corresponding structure within the locking member 112 or the connector 221 to drive the lock cylinder 222 towards or away from the locking member 112. This application embodiment does not limit this, as long as the movement of the lock cylinder 222 within the receiving cavity 2211 can be flexibly controlled.

[0042] See also some of the possible implementation methods. Figures 1 to 5 As shown, in this embodiment of the application, the mounting groove 110 extends along the vehicle height direction, the plug 221 extends along the vehicle height direction, the locking space 111 is formed by the inner wall of the mounting groove 110 being recessed radially outward, and the locking space 111 surrounds the mounting groove 110, and the radial inner end of the locking member 112 is located inside the opening of the locking space 111.

[0043] Understandably, in the vehicle's height direction (i.e., the aforementioned third direction), both the mounting groove 110 and the connector 221 extend along this third direction. The locking space 111 extends radially outward along the mounting groove 110. The radially inner end of the locking member 112 is located inside the opening of the locking space 111, thereby restricting the movement of the connector 221 relative to the mounting groove 110 along the third direction. This locks the locking engagement device 220 with the mounting groove 110, securing the battery pack 200 to the vehicle body. Simultaneously, the locking space 111 surrounds the mounting groove 110, thereby restricting the sliding of the connector 221 relative to the mounting groove 110 at multiple angles, further improving the stability of the lock between the locking engagement device 220 and the mounting groove 110.

[0044] See also some of the possible implementation methods. Figure 1 , Figure 2 and Figure 3 As shown, the housing 210 of this application embodiment has side beams 211 extending in the second direction on both sides opposite to each other along the first direction, and the plug-in members 221 are all provided on the side beams 211.

[0045] In some embodiments, the housing 210 is provided with side beams 211 on opposite sides along the first direction. The side beams 211 can protect the battery pack 200, prevent the housing 210 from direct impact, and improve the safety of the battery pack 200 and the vehicle's side impact resistance. Multiple connectors 221 are arranged at intervals along the second direction on the side beams 211. The connectors 221 can be integrally formed with the side beams 211 to improve the connection strength between the connectors 221 and the side beams 211, thereby ensuring a stable connection between the battery pack 200 and the vehicle body. Alternatively, the connectors 221 can be fixed to the side beams 211 by welding or other methods. This application embodiment does not limit this.

[0046] See also some of the possible implementation methods. Figures 1 to 5 As shown, in this embodiment of the application, the surface of the locking member 112 facing the mounting groove 110 is formed as a spherical surface, and a portion of the surface of the locking space 111 is formed as a spherical surface that is continuous with the surface of the locking member 112; the lock cylinder 222 is formed as a locking ball, and when the lock cylinder 222 and the locking member 112 are locked together, a portion of the locking ball is in contact with the spherical surface, and the other portion is locked in the connection port 2212.

[0047] In practical implementation, the lock cylinder 222 is a locking ball. The lock cylinder 222 rolls within the receiving cavity 2211 to achieve locking or disengagement with the locking member 112. Each locking member 112 corresponds one-to-one with the connecting port 2212. The surface of the locking member 112 facing the mounting groove 110 is a spherical surface. A portion of the surface of the locking space 111 is formed as a spherical surface continuing the surface of the locking member 112. The curvature of the two spherical surfaces can be consistent with the outer surface of the locking member 112. The portion of the lock cylinder 222 extending out of the connecting port 2212 fits against the spherical surfaces of the locking member 112 and the locking space 111, locking it together with the locking member 112. The other portion is located within the receiving cavity 2211 and is engaged with the connecting port 2212. Multiple lock cylinders 222 simultaneously engage with multiple locking members 112, thereby locking the locking engagement device 220 to the mounting groove 110. The inner diameter of the connection port 2212 can be set to be smaller than the diameter of the lock cylinder 222 to prevent the lock cylinder 222 from rolling out of the connection port 2212, which helps to ensure the stability of the locking device 220.

[0048] See also some of the possible implementation methods. Figures 1 to 5As shown, in this embodiment of the application, the locking member 112 is an electromagnetic member, and the locking ball is a magnetic member; when the locking member 112 is energized, the locking member 112 is in contact with the locking ball; when the locking member 112 is de-energized, the locking member 112 is out of contact with the locking ball.

[0049] In some embodiments, the locking element 112 is an electromagnetic element, and the locking ball is a magnetic element. The locking element 112 can be electrically connected to the vehicle's battery management system. By controlling the energization and de-energization of the locking element 112, the locking ball can be locked or disengaged from the locking element 112. When the locking ball is in the receiving cavity 2211, the locking element 112 is energized, and the locking element 112 attracts the locking ball to move towards the locking element 112. The locking ball passes through the corresponding connection port 2212 and connects with the locking element 112, thereby fixing the battery pack 200 to the vehicle body. When the battery pack 200 needs to be removed, the locking element 112 only needs to be de-energized. The locking ball loses the attraction of the locking element 112, thereby disengaging from the locking element 112 and returning to the receiving cavity 2211. The locking engagement device 220 disengages from the mounting groove 110, and the battery pack 200 falls off the vehicle body.

[0050] See also some of the possible implementation methods. Figures 1 to 5 As shown, in this embodiment of the application, the inner wall of the receiving cavity 2211 with the connection port 2212 is at least partially inclined.

[0051] It should be noted that the inner wall of the receiving cavity 2211 can be partially inclined inward. In this way, when the locking member 112 is de-energized, the locking ball can roll down along the inclined inner wall under the action of gravity and thus retract into the receiving cavity 2211. This prevents the locking ball from getting stuck at the connection port 2212 and affecting the disassembly of the battery pack 200, which helps to improve the disassembly efficiency of the battery pack 200.

[0052] See also some of the possible implementation methods. Figures 1 to 5 As shown, the inner wall of the receiving cavity 2211 in this embodiment of the application has multiple guide grooves (not shown in the figure), one end of the guide groove is connected to the connection port 2212, and the lock cylinder 222 is correspondingly disposed in the guide groove.

[0053] It is understandable that guide grooves can also be formed on the inner wall of the receiving cavity 2211. Each guide groove corresponds to a locking ball, with one end connected to the connection port 2212 and the other end located inside the receiving cavity 2211. When the locking element 112 is de-energized, the locking ball rolls along the guide groove back into the receiving cavity 2211. When the locking element 112 is energized, the locking ball moves along the guide groove to the corresponding connection port 2212 and forms a locking engagement with the locking element 112. This ensures that when the locking element 112 is energized, the locking ball can accurately move to the corresponding connection port 2212, preventing deviation of the locking ball's movement path that could prevent some locking elements 112 from forming a locking engagement with the locking ball. This improves the stability of the connection between the locking engagement device 220 and the mounting groove 110.

[0054] See also some of the possible implementation methods. Figure 1 , Figure 2 , Figure 4 and Figure 6 As shown, the battery pack 200 in this embodiment of the application further includes: a cell module 230 and a detection unit 240. The cell module 230 is disposed in the inner cavity of the housing 210. The detection unit 240 is used to detect the operating condition information of the cell, including temperature and voltage. The vehicle further includes: a control unit 300, which is electrically connected to the detection unit 240 and the locking member 112 respectively, so as to control the working state of the locking member 112 according to the detection result of the detection unit 240.

[0055] In practical implementation, if the cell module 230 experiences thermal runaway, it will rapidly generate a large amount of high-temperature gas, causing the entire battery pack 200 and even the vehicle to catch fire. To ensure the safety of the vehicle's occupants, a detection unit 240 can be installed inside the battery pack 200. The detection unit 240 can monitor the operating conditions of the cell module 230 in real time to determine whether the battery pack 200 is at risk of thermal runaway. For example, the operating conditions can include voltage and temperature. When the detection unit 240 detects that the voltage is greater than the preset voltage value or the temperature is greater than the preset temperature value, it proves that the battery pack 200 is at risk of thermal runaway or has already experienced thermal runaway. At this time, the control unit 300 controls the locking component 112 to cut off the power, allowing the battery pack 200 to quickly detach from the vehicle body under its own weight. This can prevent the battery pack 200 from causing the entire vehicle to catch fire, providing time for the occupants to escape. At the same time, the separation of the battery pack 200 from the vehicle body also helps to reduce the difficulty of fire rescue, thereby ensuring the safety of the occupants. The operating condition information can also be other information such as current. This application embodiment does not impose any restrictions, as long as it can promptly determine the thermal runaway state of the battery pack 200.

[0056] See also some of the possible implementation methods. Figure 1 , Figure 2 , Figure 4 and Figure 6As shown, the embodiments of this application also include: an alarm unit; the alarm unit is electrically connected to the control unit 300, and the control unit 300 is further configured to control the working state of the alarm unit according to the detection result of the detection unit 240.

[0057] Specifically, the alarm unit may include alarm devices such as buzzers and warning lights, which can promptly notify the driver and passengers that the battery pack 200 is in a thermal runaway state through sound signals and optical signals, so that the driver and passengers can react in time, escape the vehicle, and avoid danger. At the same time, the alarm unit may also include a communication device. When the battery pack 200 experiences thermal runaway, the control unit 300 can promptly send alarm information through the communication device so that firefighters can quickly arrive at the scene for rescue, which helps to reduce the losses caused by the thermal runaway of the battery pack 200.

[0058] See also some of the possible implementation methods. Figure 1 , Figure 2 , Figure 4 and Figure 6 As shown, the embodiments of this application also include: a remote control unit, which is communicatively connected to the control unit 300, and the remote control unit controls the engagement state of the locking member 112 and the locking engagement device 220 through the control unit 300.

[0059] It is understandable that, in addition to controlling the engagement state of the locking member 112 and the locking engagement device 220 based on the operating condition information of the battery pack 200, a remote control unit can also be set up. When the battery pack 200 needs to be repaired, the remote control unit can be used to control the locking member 112 and the locking engagement device 220 to lock or disengage, thereby completing the installation and disassembly of the battery pack 200, which is beneficial to improving the maintenance efficiency of the battery pack 200.

[0060] In summary, the vehicle provided in this application embodiment includes a vehicle body and a battery pack 200. The vehicle body has a mounting beam 100 with multiple mounting slots 110. Each mounting slot 110 contains a locking member 112. The battery pack 200 includes a housing 210 and a locking engagement device 220. The locking engagement device 220 includes a connector 221 and a lock cylinder 222. The connector 221 is inserted into the mounting slot 110 and has a receiving cavity 22. 11. Multiple connection ports 2212 are provided around the circumference of the connector 221 to communicate with the receiving part. Each connection port 2212 corresponds to a locking member 112. The locking cylinder 222 moves within the receiving cavity 2211 to pass through the connection port 2212 and lock with the locking member 112, thereby fixing the battery pack 200 to the vehicle body. Alternatively, the locking cylinder 222 retracts into the receiving cavity 2211 and disengages from the locking member 112, thereby detaching the battery pack 200 from the vehicle body. In this way, when the battery pack 200 is under maintenance, the installation and removal of the battery pack 200 can be completed by controlling the movement of the locking cylinder 222 within the receiving cavity 2211. This is convenient and helps to improve the maintenance efficiency of the battery pack 200. At the same time, when the battery pack 200 experiences problems such as thermal runaway, the locking cylinder 222 can be controlled to retract into the receiving cavity 2211, allowing the battery pack 200 to quickly detach from the vehicle body so that the vehicle occupants can escape in time and improve their safety.
