[0063] In the embodiments of this application, words such as "exemplarily" or "for example" are used to indicate examples, illustrations, or explanations. Any embodiment or design described as "exemplarily" or "for example" in the embodiments of this application should not be interpreted as being preferred or advantageous over other embodiments or designs. Rather, the use of words such as "exemplarily" or "for example" is intended to present the relevant concepts in a concrete manner.

[0064] See also Figures 1-11 In a first aspect, embodiments of the present application provide a battery pack assembly 100, which is applied to a vehicle 1000 and includes a battery pack 1, a compartment 7, and a locking structure 2. A plug-in portion 74 is provided at one end of the compartment 7, which allows the battery pack 1 to be inserted into the interior space 78 of the compartment 7. The walls of the compartment 7 can limit the battery pack 1 to a certain extent, so that the battery pack 1 can be installed in the compartment 7.

[0065] Optionally, the plug-in portion 74 may be an opening, the opening being in communication with the inner space 78 of the accommodating compartment 7 , and the battery pack 1 may be inserted into the inner space 78 of the accommodating compartment 7 through the opening.

[0066] Optionally, the plug-in portion 74 may further include a switch door for opening or closing an opening connected to the internal space 78 of the accommodating compartment 7 . When the switch door is open, the battery pack 1 may be inserted into the internal space 78 of the accommodating compartment 7 through the opening.

[0067] The locking structure 2 is provided on the wall of the accommodating compartment 7 , and the locking structure 2 has a first state. Alternatively, the locking structure 2 can be provided on the bottom wall 71 , the top wall or the side wall of the accommodating compartment 7 .

[0068] When the locking structure 2 is in the first state, at least a portion of the locking structure 2 is located within the internal space 78, cooperating with the battery pack 1 to prevent movement of the battery pack 1 in the insertion direction (as indicated by direction e1 in the figure) and in the opposite direction of insertion (as indicated by direction e2 in the figure). By operating the locking structure 2 to transition to the first state, a locking engagement is established between the locking structure 2 and the battery pack 1, enabling rapid locking between the battery pack 1 and the wall of the accommodating compartment 7. This allows the battery pack 1 to be stably installed within the accommodating compartment 7, simplifying installation.

[0069] When the locking structure 2 is in the first state, at least a portion of the locking structure 2 is located in the internal space 78, which may include the following situations: For example, when the locking structure 2 is in the first state, a portion of the locking structure 2 is located in the internal space 78, and this portion of the locking structure 2 can cooperate with the battery pack 1 located in the internal space 78. For another example, when the locking structure 2 is in the first state, the entire locking structure 2 is located in the internal space 78, and the locking structure 2 can cooperate with the battery pack 1 located in the internal space 78.

[0070] It should be noted that the internal space 78 of the accommodating compartment 7 refers to the space area in the accommodating compartment 7 that can be used to place the battery pack 1, that is, the space area composed of the area where the relevant structures on the accommodating compartment 7 will not interfere with the battery pack 1.

[0071] Illustratively, the locking structure 2 can form a mating relationship with the battery pack 1 in a direction perpendicular to the insertion direction to prevent the battery pack 1 from moving in the insertion direction and in a direction opposite to the insertion direction. For example, if the length direction of the battery pack 1 is consistent with the insertion direction of the battery pack 1, the locking structure 2 can form a mating relationship with the battery pack 1 in the thickness direction of the battery pack 1 or the width direction of the battery pack 1, or the locking structure 2 can form a mating relationship with the battery pack 1 in both the thickness direction and the width direction of the battery pack 1.

[0072] Exemplarily, the locking structure 2 can be extended or moved in a direction perpendicular to the insertion direction to form a matching relationship with the battery pack 1 .

[0073] Optionally, a matching structure is provided on the battery pack 1, and the locking structure 2 is locked and matched with the matching structure. For example, the matching structure may be a groove, a limiting hole, etc.

[0074] Optionally, the battery pack 1 includes a battery pack body 11 and a bracket 12 fixed to the battery pack body 11 , and the bracket 12 is provided with a matching structure capable of matching with the locking structure 2 .

[0075] Optionally, a plurality of locking structures 2 are provided at intervals.

[0076] According to the battery pack assembly 100 of the embodiment of the present application, the accommodating compartment 7 allows the battery pack 1 to be directly inserted into the internal space 78 of the accommodating compartment 7 by providing the plug-in portion 74, so that the accommodating compartment 7 forms a certain limiting effect on the battery pack 1; further, through the cooperation of the locking structure 2 and the battery pack 1, the battery pack 1 can be quickly locked with the wall of the accommodating compartment 7, which can prevent the battery pack 1 from moving arbitrarily in the insertion direction or the opposite direction, thereby facilitating the stable installation of the battery pack 1 in the accommodating compartment 7, thereby making the installation operation of the battery pack 1 simple.

[0077] In some optional embodiments, the locking structure 2 further has a second state, and the locking structure 2 can move between the first state and the second state. When the locking structure 2 is in the second state, the locking structure 2 is located outside the internal space 78.

[0078] By operating the locking structure 2 to move it from the first state to the second state, the locking structure 2 can achieve a locking and matching relationship with the battery pack 1.

[0079] Optionally, the locking structure 2 may be operated manually or automatically to move the locking structure 2 from the first state to the second state.

[0080] Among them, the outside of the internal space 78 can be the inside of the wall of the accommodating compartment 7, that is, the locking structure 2 is arranged using the space of the wall itself, or an avoidance installation area is formed on the wall for setting the locking structure 2; the outside of the internal space 78 can also be the outside of the wall of the accommodating compartment 7, that is, the locking structure 2 is located outside the wall, but it will not interfere with the placement of the battery pack 1, and the space occupied by the locking structure 2 outside the wall does not belong to the internal space 78.

[0081] The locking structure 2 being located outside the internal space 78 may mean that the entire locking structure 2 is located outside the internal space 78 , or that part of the locking structure 2 is located outside the internal space 78 .

[0082] By enabling the locking structure 2 to switch between the first state and the second state, the locking mechanism not only effectively prevents the battery pack 1 from sliding or falling out in the insertion direction and the opposite direction during use, but also ensures that the battery pack 1 can be quickly removed with simple operations when necessary. For example, in an emergency, the battery pack 1 can be quickly removed, which helps improve the safety of the vehicle 1000.

[0083] See also Figure 1-Figure 2 Combined with Figures 8-12 In some optional embodiments, the locking structure 2 includes a locking member 21 and a driving structure 22. The driving structure 22 is connected to the locking member 21 and is configured to drive the locking member 21 to move along a first direction from a first position to a second position. When the locking member 21 is in the first position, the locking member 21 is located outside the interior space 78, and the locking structure 2 is in the second state. When the locking member 21 is in the second position, at least a portion of the locking member 21 is located within the interior space 78, and the locking structure 2 is in the first state.

[0084] Exemplarily, the locking member 21 may be a post, a pin, a hook, a block, or the like mechanical component.

[0085] Exemplarily, the driving structure 22 may be a motor, a hydraulic cylinder, a pneumatic device, or a manual operating mechanism.

[0086] Optionally, the first direction may be any direction intersecting the insertion direction, for example, the first direction may be a direction perpendicular to the insertion direction.

[0087] Optionally, the locking member 21 can slide, swing, or rotate between the first position and the second position.

[0088] Among them, at least a portion of the locking member 21 is located in the internal space 78 , including the following situations: for example, a portion of the locking member 21 is located in the internal space 78 ; for another example, the entire locking member 21 is located in the internal space 78 .

[0089] Illustratively, when the battery pack 1 is correctly installed, the drive structure 22 moves the locking member 21 from the first position to the second position, and the locking structure 2 switches to the previous first state to ensure the safe fixation of the battery pack 1 so that the battery pack 1 is stably installed in the internal space 78 of the accommodating compartment 7.

[0090] For example, when the battery pack 1 needs to be replaced, or when an emergency occurs and the battery pack 1 needs to be removed, the drive structure 22 drives the locking member 21 to move from the second position to the first position, so that the locking structure 2 switches from the first state to the second state, at which time the battery pack 1 can be easily inserted or removed. By providing the drive structure 22, the position of the locking member 21 can be flexibly controlled by the drive structure 22 according to the requirements of the use scenario of the battery pack 1 to achieve control of the matching relationship between the locking structure 2 and the battery pack 1. In addition, the drive structure 22 can accurately drive the locking member 21 to the desired position, ensuring that each locking action is accurate and correct, thereby enhancing the reliability of the system.

[0091] See also Figures 8-12 In some optional embodiments, the driving structure 22 includes a first elastic member 221 and a stop member 222, the first elastic member 221 is connected to the locking member 21, and the stop member 222 can move from the locked position to the unlocked position.

[0092] When the stopper 222 is in the locked position, the stopper 222 prevents the locking member 21 from moving toward the internal space 78, and causes the first elastic member 221 to be in an elastic deformation state to accumulate elastic force directed toward the internal space 78; when the stopper 222 is in the unlocked position, the stopper 222 releases the locking member 21, and the elastic force drives the locking member 21 to move toward the internal space 78.

[0093] During the assembly process of the battery pack assembly 100, the stop member 222 can be used to limit the locking member 21. The existence of the stop member 222 ensures that the locking member 21 will only move from the second position to the first position under specific operations, such as manual operation or receipt of an automated control signal. This avoids malfunction of the locking member 21 due to accidental touch or other unexpected situations, thereby improving the safety of the system.

[0094] For example, the action of switching the stopper 222 from the locked position to the unlocked position can be performed manually or automatically by electric, pneumatic or other means.

[0095] By setting the first elastic member 221, the first elastic member 221 can provide kinetic energy for the locking member 21, and the elastic force accumulated by the first elastic member 221 can act quickly at the moment when the stop member 222 releases the locking member 21, quickly pushing the locking member 21 into the correct position, that is, entering the internal space 78 and forming a matching relationship with the battery pack 1.

[0096] By setting the stopper 222, the operator only needs to perform simple operations (such as pressing a button, pulling a pull ring) to complete the complex locking / unlocking process. When the stopper 222 switches from the locked position to the unlocked position, the first elastic member 221 can automatically respond and complete the subsequent actions, which is conducive to further simplifying the user's operating steps.

[0097] See also Figure 12 In some optional embodiments, the stopper 222 is connected to a handle 2221, and the handle 2221 is used to drive the stopper 222 to move from the locked position to the unlocked position. By providing the handle 2221, the operator can operate more easily.

[0098] For example, the handle 2221 may be a pull ring structure, and the operator may hold the pull ring and pull the stopper 222 to drive the stopper 222 to move from the indicated position to the unlocked position.

[0099] See also Figure 10-11 In some optional embodiments, the locking structure 2 further includes a first clamping portion 31 and a second clamping portion 32. The first clamping portion 31 is relatively fixed to the wall of the accommodating compartment 7, and the second clamping portion 32 is provided on the locking member 21. The locking member 21 can also move from the second position to the third position in the opposite direction of the first direction. When the locking member 21 is in the third position, the second clamping portion 32 cooperates with the first clamping portion 31 to clamp, and the locking member 21 is located outside the internal space 78.

[0100] Exemplarily, the locking structure 2 is provided on the bottom wall 71 of the accommodating compartment 7, and the first clamping portion 31 is relatively fixed to the bottom wall 71 of the accommodating compartment 7. Exemplarily, the locking structure 2 is provided on the side wall of the accommodating compartment 7, and the first clamping portion 31 is relatively fixed to the side wall of the accommodating compartment 7.

[0101] When the locking structure 2 switches from the first state to the second state, the locking member 21 can move in the opposite direction of the first direction to disengage the locking structure 2 and the battery pack 1 .

[0102] By providing a first clamping portion 31 and a second clamping portion 32 that cooperate with each other, during the process of switching the locking structure 2 from the first state to the second state, when the locking member 21 moves to the third position, a stable clamping relationship is formed between the first clamping portion 31 and the second clamping portion 32, which can enable the locking member 21 to be stably maintained outside the internal space 78, thereby preventing the locking member 21 from interfering with further disassembly and assembly of the battery pack 1.

[0103] See also Figure 3 as well as Figures 8-12 In some optional embodiments, the locking structure 2 further includes a fixed cylinder 4, which is disposed on the wall of the accommodating compartment 7, and the locking member 21, the driving structure 22 and the first clamping portion 31 are all disposed on the fixed cylinder 4.

[0104] The fixed cylinder 4 provides a stable guide path for the locking member 21 , ensuring the accuracy and stability of the locking member 21 during movement. The locking member 21 can stably move between the first position and the second position under the driving action of the driving structure 22 .

[0105] By setting up a fixed cylinder body 4, the locking member 21, the driving structure 22 and the first clamping portion 31 are integrated in the fixed cylinder body 4. The fixed cylinder body 4 can effectively protect these components, reduce or prevent the entry of dust, moisture and other pollutants, thereby reducing the impact of these factors on the locking structure 2, which is beneficial to improving the reliability and service life of the locking structure 2.

[0106] Illustratively, the assembly process of the battery pack assembly 100 may include the following steps: first, the battery pack 1 is inserted into the internal space 78 of the accommodating compartment 7 through the plug-in portion 74; then, the handle 2221 is manually pulled to move the stop member 222 from the locked position to the unlocked position, and the stop member 222 releases the locking member 21, thereby causing the elastic force accumulated by the elastic member 221 and directed toward the internal space 78 to drive the locking member 21 to move toward the internal space 78; finally, the locking member 21 moves from the second position to the first position, thereby switching the locking structure 2 from the second state to the first state, and forming a mating relationship with the battery pack 1, and the battery pack 1 is installed in the accommodating compartment 7.

[0107] Exemplarily, the disassembly process of the battery pack assembly 100 may include the following steps: first, the locking member 21 is moved from the first position to the third position in the opposite direction of the first direction to enable the first clamping portion 31 and the second clamping portion 32 to switch the locking structure 2 from the first state to the second state, and the locking structure 2 and the battery pack 1 are disengaged; then, the battery pack 1 can be removed from the internal space 78 of the accommodating compartment 7 via the plug-in portion 74.

[0108] Optionally, a positioning shaft 23 is fixedly connected to the bottom surface of the fixed cylinder 4 , and the locking member 21 is sleeved on the outer side of the positioning shaft 23 and can move relative to the positioning shaft 23 .

[0109] A limiting member is further provided at one end of the positioning shaft 23 away from the bottom surface. When the locking member 21 moves to the first position, the locking member 21 abuts against the limiting member.

[0110] See also Figure 5-Figure 11In some optional embodiments, the battery pack 1 includes a battery pack body 11 and an unlocking structure 5 connected to the battery pack body 11. The unlocking structure 5 is used to drive the locking structure 2 from the first state to the second state. By integrating the unlocking function into the battery pack body 11, it can automatically trigger the locking structure 2 on the accommodating compartment 7 to unlock, thereby achieving more efficient and intelligent unlocking of the battery pack 1 and the locking structure 2, facilitating the removal of the battery pack 1.

[0111] Optionally, the power used by the unlocking structure 5 to drive the locking structure 2 to move from the first state to the second state may come from the battery pack body 11 or from a separately provided driving component.

[0112] Optionally, the unlocking structure 5 can be a hydraulic or pneumatic driven structure, or a connecting rod linkage, electric gear driven structure, etc. For example, when the locking structure 2 needs to be unlocked, the locking structure 2 can be controlled to move by the pneumatic driven structure.

[0113] See also Figure 5-Figure 11 In some optional embodiments, the unlocking structure 5 includes a telescopic device that can be extended to push the locking structure 2 from the first state to the second state.

[0114] For example, when the battery pack 1 needs to be removed from the accommodating compartment 7, the telescopic device on the battery pack 1 starts to work, for example, the telescopic device can be extended by electric, pneumatic or hydraulic drive.

[0115] By providing a telescopic device, the telescopic device can provide a stable and controllable thrust by extending, ensuring that the locking structure 2 accurately moves from the first state to the second state, so that the battery pack 1 can be disengaged from the locking structure 2.

[0116] See also Figure 5-Figure 11 In some optional embodiments, the telescopic device includes a telescopic cylinder 51 that communicates with the internal space 78 of the battery pack body 11, or a pressure relief valve is provided between the telescopic cylinder 51 and the internal space 78 of the battery pack body 11. In this way, the telescopic cylinder 51 can automatically respond to the gas within the battery pack body 11, causing it to extend, thereby providing power to the locking structure 2, allowing the locking structure 2 to move from the first state to the second state. In this way, when a large amount of gas is generated within the battery pack body 11 due to an emergency such as thermal runaway, the locking structure 2 can automatically respond and unlock, allowing the battery pack 1 to be removed, thereby preventing it from causing further damage to the vehicle 1000 or causing a more serious safety accident.

[0117] Optionally, the pressure relief valve can be connected to the telescopic cylinder 51 through a pipe 52. In this way, when the pressure relief valve is opened, high-pressure gas will reach the telescopic cylinder 51 through the pipe 52, pushing it to extend, thereby driving the locking structure 2 to switch from the first state to the second state.

[0118] For example, when the battery pack body 11 experiences thermal runaway, the temperature rises sharply, causing a series of irreversible chemical reactions inside the battery pack body 11. These reactions generate a large amount of heat and gas, which accumulate inside the battery pack body 11. These gases can enter the telescopic cylinder 51 and push it to extend, thereby driving the locking structure 2 to switch from the first state to the second state.

[0119] See also Figures 8-11 In some optional embodiments, the battery pack 1 further includes a bracket 12, on which both the battery pack body 11 and the unlocking structure 5 are mounted. By integrating the battery pack body 11 and the unlocking structure 5 on a single bracket 12, the assembly process is simplified, the modularity of the system is improved, and maintenance and replacement are facilitated.

[0120] For example, a special pipe 52 may be designed inside the bracket 12 , and the pipe 52 can collect and guide the high-pressure gas generated inside the battery pack 1 to the telescopic cylinder 51 .

[0121] Optionally, the bracket 12 is provided with a matching structure that matches the locking structure 2 .

[0122] Optionally, the bracket 12 is a die-cast structure.

[0123] See also Figures 1-6 In some optional embodiments, a first plug connector 61 is provided at the end of the accommodating compartment 7 away from the plug-in portion 74, and a second plug connector 62 is provided at the front end of the battery pack 1 along the insertion direction. When the battery pack 1 is inserted into the internal space 78, the second plug connector 62 mates with the first plug connector 61. During the insertion of the battery pack 1 into the internal space 78 of the accommodating compartment 7, the first plug connector 61 and the second plug connector 62 can be docked. In this way, the operator only needs to insert the battery pack 1 into the accommodating compartment 7 and ensure that it is properly installed. The second plug connector 62 and the first plug connector 61 automatically complete the electrical connection, eliminating the need for additional manual operation steps, which helps to further simplify the installation operation.

[0124] See also Figure 2 and Figure 4In some optional embodiments, a second elastic member 76 is provided at one end of the accommodating compartment 7 away from the plug-in portion 74. When the battery pack 1 is inserted into the internal space 78, the second elastic member 76 elastically deforms and generates an elastic force directed toward the battery pack 1. The elastic force of the second elastic member 76 directed toward the battery pack 1 can further enhance the installation stability of the battery pack 1 in the internal space 78 of the accommodating compartment 7. When the battery pack 1 needs to be removed from the accommodating compartment 7, the elastic force directed toward the battery pack 1 provided by the elastic member 221 can also help to more easily remove the battery pack 1. For example, when the battery pack 1 needs to be removed from the accommodating compartment 7, the second elastic member 76 can disengage the first plug connector 61 and the second plug connector 62.

[0125] In addition, during the driving of the vehicle 1000 , the elastic member 221 can absorb part of the vibration energy, reducing the impact on the battery pack 1 and its internal components.

[0126] See also Figure 2 In some optional embodiments, the accommodating compartment 7 includes a bottom wall 71, the surface of which facing the interior space 78 is a first surface 711. The first surface 711 slopes downward, extending from the end of the accommodating compartment 7 away from the plug-in portion 74 toward the plug-in portion 74. The sloped first surface 711 acts as a natural guide, facilitating the movement of the battery pack 1 relative to the accommodating compartment 7 from within the accommodating compartment 7 toward the plug-in portion 74, thereby facilitating removal of the battery pack 1 from the accommodating compartment 7.

[0127] For example, when the battery pack body 11 experiences thermal runaway, the pressure relief valve opens, and the high-pressure gas in the battery pack body 11 reaches the telescopic cylinder 51 through the pipe 52, pushing it to extend, thereby driving the locking structure 2 to switch from the first state to the second state, and the locking structure 2 and the battery pack 1 are disengaged from the locking relationship. At this time, the elastic force of the second elastic member 76 pointing to the battery pack 1 can drive the battery pack 1 to move along the first surface 711 toward the plug-in portion 74, and move to the outside of the accommodating compartment 7 under the action of the inclined first surface 711.

[0128] See also Figure 2In some optional embodiments, the inclination angle of the first surface 711 is greater than or equal to 3° and less than or equal to 5°. Exemplarily, the inclination angle of the first surface 711 may be 3°, 4°, 4.5° or 5°, etc. If the inclination angle of the first surface 711 is less than 3°, the inclination angle is too small, which will cause the first surface 711 to be almost horizontal and unable to effectively guide the movement of the battery pack 1; if the inclination angle of the first surface 711 is greater than 5°, the large inclination angle will make it easier for the battery pack 1 to "slide" due to gravity, thereby affecting the alignment accuracy of the plug connector and increasing the difficulty of installing the battery pack 1. By making the inclination angle of the first surface 711 greater than or equal to 3° and less than or equal to 5°, the first surface 711 can effectively guide the movement of the battery pack 1 without increasing the difficulty of installing the battery pack 1.

[0129] See also Figure 2-Figure 3 Combined with Figures 8-11 In some optional embodiments, the locking structure 2 is provided on the bottom wall 71. The bottom wall 71 can provide stable support for the locking structure 2. Exemplarily, the locking member 21 of the locking structure 2 can move between a first position and a second position in a direction perpendicular to the bottom wall 71, so that the locking structure 2 can switch between the first state and the second state.

[0130] Optionally, a sinking groove is provided on the bottom wall 71, and the fixed cylinder body 4 is fixed in the sinking groove.

[0131] See also Figure 1-Figure 4 In some optional embodiments, the accommodating compartment 7 includes a bottom wall 71, a cover 72, and an end cover 73, with the cover 72 being connected to the bottom wall 71. The bottom wall 71, the cover 72, and the end cover 73 together form an internal space 78 for accommodating the battery pack 1. Exemplarily, a second elastic member 76 and a first plug connector 61 are provided on a portion of the end cover 73 that is opposite the plug-in portion 74 along the first direction.

[0132] Optionally, the cover 72 may be a metal cover 72 , for example, a steel cover 72 .

[0133] Optionally, a reinforcement structure 721 is provided on the cover body 72 to help improve the overall structural strength of the cover body 72 .

[0134] See also Figure 1-Figure 4In some optional embodiments, the accommodating compartment 7 includes a bottom wall 71, a cover body 72 and an end cover 73. The cover body 72 is connected to the bottom wall 71. The plug-in portion 74 and the end cover 73 are arranged between the opposite ends of the cover body 72 and the bottom wall 71. The bottom wall 71, the cover body 72, the end cover 73 and the plug-in portion 74 form an internal space 78, which can effectively prevent dust, moisture and other pollutants in the external environment from entering, thereby avoiding damage to the battery pack 1 and its internal components, and can also form an effective limiting effect on the battery pack 1 to prevent the battery pack 1 from shaking at will.

[0135] See also Figure 1-Figure 3 In some optional embodiments, the bottom wall 71 is provided with a connecting portion 79, and the edge of the cover 72 is connected to the connecting portion 79. This is conducive to the stable installation of the cover 72 to ensure that it can effectively cover the internal space 78.

[0136] Optionally, a connecting protrusion 7211 is formed on one end of the reinforcement structure 721 facing the bottom wall 71, and the connecting protrusion 7211 can be received in the connecting portion 79 to connect the cover 72 to the bottom wall 71. Exemplarily, the connecting protrusion 7211 is formed as a round head structure, and an arc-shaped mounting groove is formed in the connecting portion 79, and the mounting grooves are used to accommodate the round head structure.

[0137] See also Figure 1-Figure 2 Combined with Figure 13 In some optional embodiments, the plug-in portion 74 is a door 75 provided at one end of the accommodating compartment 7, and the door 75 is used to open or close the internal space 78. Thus, after the battery pack 1 is inserted into the internal space 78, the internal space 78 can be closed by opening and closing the door, thereby effectively protecting the internal battery pack 1 and other structures from the influence of the external environment.

[0138] Optionally, the door 75 can be connected to the cover 72 via a hinge structure 77, and the door 75 can rotate relative to the cover 72 to open or close the internal space 78. The hinge structure 77 can be connected between the cover 72 and the door 75 by spot welding.

[0139] See also Figure 2-Figure 3 In some optional embodiments, the battery pack assembly 100 further includes a guide rail 8 disposed within the interior space 78 and extending along the insertion direction of the battery pack 1. The guide rail 8 cooperates with the battery pack 1 to guide the insertion direction of the battery pack 1. The provision of the guide rail 8 provides guidance for the battery pack 1, ensuring that the battery pack 1 is accurately installed into the accommodating compartment 7 along a predetermined path. This further avoids problems such as misalignment caused by improper manual operation.

[0140] Optionally, the guide rail 8 is an extruded part, and the guide rail 8 is an aluminum part.

[0141] Optionally, the battery pack 1 is provided with a roller assembly 13, which can be correspondingly accommodated in the guide rail 8 and move relative to the guide rail 8. Specifically, the roller assembly 13 includes a roller fixing structure 132 and a roller 131 rotatably mounted on the roller fixing structure 132. The roller assembly 13 also includes a welding fixing ring 133, which is fixedly connected between the roller fixing structure 132 and the battery pack 1. The roller assembly 13 also includes a fastener 134, which is used to fix the roller 131 to the roller fixing structure 132. The roller assembly 13 also includes a gasket 135, which is located between the fastener 134 and the roller 131.

[0142] Exemplarily, roller assemblies 13 are provided on both sides along the width direction of the battery pack 1, and multiple roller assemblies 13 are provided on one side, for example, four, six, eight or nine roller assemblies 13 are provided on one side.

[0143] Optionally, the A surface of the roller fixing structure 132 is about 3-5 mm lower than the roller 131, so that the roller 131 can roll smoothly. The end surface of the roller fixing structure 132 is about 0.5-1 mm higher than the roller 131, which is conducive to ensuring the installation stability of the roller 131.

[0144] Optionally, the guide rail 8 is welded to the bottom wall 71 .

[0145] For example, during the assembly of the battery pack assembly 100 , the installation can be completed by aligning the roller assembly 13 of the battery pack 1 with the entrance of the guide rail 8 and gently pushing it in, which greatly simplifies the operation steps.

[0146] Optionally, the guide rail 8 has a track 83 , and the roller 131 can be accommodated in the track 83 and can roll along the track 83 .

[0147] See also Figure 2-Figure 3 In some optional embodiments, guide rail 8 includes opposing second guide rails 81 and 82 , spaced apart and perpendicular to the insertion direction of battery pack 1. Both second guide rails 81 and 82 cooperate with battery pack 1 to guide insertion. Thus, second guide rails 81 and 82 are located on either side of battery pack 1, providing dual-sided guidance and support, ensuring that battery pack 1 maintains the correct orientation throughout insertion, and avoiding tilting or misalignment that could be caused by a single-sided guide rail 8 .

[0148] Optionally, both the first guide rail 81 and the second guide rail 82 have a track 83, so that the first guide rail 81 and the second guide rail 82 can effectively limit the roller along the arrangement direction of the first guide rail 81 and the second guide rail 82 and the height direction, and thus can effectively limit the battery pack 1.

[0149] See also Figure 1-Figure 2 In a second aspect, the present application provides a vehicle 1000, which can be a fuel-powered vehicle, an electric vehicle, a hybrid vehicle, a gas vehicle, a methanol vehicle, a solar vehicle, etc. Furthermore, the vehicle 1000 can be a passenger vehicle such as a sedan, a Sport Utility Vehicle (SUV), or a Multi-Purpose Vehicle (MPV), or can also be a bus, a truck, or a semi-trailer, etc., and the present application does not impose any specific restrictions on this.

[0150] In some embodiments, a vehicle 1000 includes the aforementioned battery pack assembly 100. The battery pack assembly 100 is easy to install and operate, thereby improving the production efficiency of the vehicle 1000.

[0151] In some optional embodiments, a vehicle 1000 includes a vehicle body 10, and a battery pack assembly 100 is disposed above a top wall of the vehicle body 10. The battery pack assembly 100 reduces the space occupied by the interior of the vehicle body 10, and the operating space above the top wall of the vehicle body 10 is larger, facilitating the installation of the battery pack assembly 100.

[0152] In some embodiments, the vehicle 1000 is integrated with a power generation device above the top wall of the vehicle body 10. For example, the power generation device is a solar power generation device or a wind power generation device. The power generation device can charge the battery pack 1 of the vehicle 1000 to provide power for certain electrical systems of the vehicle 1000.

[0153] Specifically, the power generation device may include the above-mentioned battery pack assembly 100 and a solar panel. Solar energy can convert sunlight energy into electrical energy, and the battery pack 1 is used to store the electrical energy converted by the solar panel.

[0154] For example, a solar panel can be composed of a plurality of photovoltaic cells.

[0155] For example, the power generation device is located on the top of vehicle body 10, that is, on the roof. This prevents the power generation device from occupying interior space 78 of vehicle 1000, preserving space for passengers and cargo. Furthermore, it increases the contact area between the power generation device and the external environment, enabling the power generation device to efficiently convert energy.

[0156] In some optional embodiments, when the battery pack assembly 100 is used in a solar power generation device, the solar power generation device includes a solar panel connected to the accommodating compartment 7, and the second plug connector 62 of the battery pack 1 and the first plug connector 61 of the accommodating compartment 7 are electrically connected to form a safe and reliable charging path from the solar panel to the battery pack 1.

[0157] Optionally, a solar panel is disposed on the cover 72 .

[0158] In the description of the embodiments of the present application, specific features, structures, materials or characteristics may be combined in an appropriate manner in any one or more embodiments or examples.

[0159] The above are only specific embodiments of the present application, but the scope of protection of this application is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in this application should be included in the scope of protection of this application. Therefore, the scope of protection of this application should be based on the scope of protection of the claims.
