In order to provide sufficient power for new energy vehicles and meet the long endurance demand, a battery pack with large volume and heavy weight is generally assembled on the new energy vehicle.

[0003] In the related art, when assembling the battery pack on the vehicle, an assembler first needs to drive a forklift or other transfer tool with the battery pack to move the battery pack to a designated position. Then the battery pack is unloaded from the transfer tool. Finally, multiple assemblers cooperate to tighten each bolt for connecting the battery pack and the vehicle body by manual mode to complete the assembly.

[0054] The specific embodiments of the present application have been shown by the above-mentioned drawings, and will be described in more detail hereinafter. These drawings and textual descriptions are not intended to limit the scope of the concept of the present application by any means, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0055] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0056] Unless otherwise defined, all technical terms used in the embodiments of this application have the same meaning as commonly understood by those skilled in the art.

[0057] To make the technical solutions and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0058] Firstly, combining Figure 1 and Figure 2 As shown in the figure, this application provides a vehicle, which includes a body 100, a battery pack 200 and a locking mechanism 300.

[0059] The vehicle body 100 includes a body component 110 and a mounting bracket 120. The mounting bracket 120 is mounted on the ground-facing side of the body component 110 and has a first guide groove 121 and a second guide groove 122 disposed opposite to each other. It is understood that the interior of the body component 110 is used to provide a cabin for the user and to house various devices. In some embodiments, the mounting bracket 120 may include a first mounting member 128 and a second mounting member 129 disposed opposite to each other. The first mounting member 128 has a first guide groove 121 on the side facing the second mounting member 129, and the second mounting member 129 has a second guide groove 122 on the side facing the first mounting member 128. The first guide groove 121 is recessed in a direction away from the second mounting member 129, and the second guide groove 122 is recessed in a direction away from the first mounting member 128. It should be noted that the extending direction of the first guide groove 121 and the extending direction of the second guide groove 122 are the same, for example, they may be parallel to the length or width direction of the body component 110.

[0060] The battery pack 200 includes a housing 210, a first guide 220, and a second guide 230. The housing 210 includes a first side 211 and a second side 212 facing each other. The first guide 220 and the second guide 230 are respectively connected to the first side 211 and the second side 212. It is understood that the battery pack 200 also includes a power battery module, which can be installed within the housing 210 and can provide power for the vehicle's operation.

[0061] The locking mechanism 300 is mounted on the main body 110 and can switch between an unlocked state and a locked state.

[0062] The first guide 220 moves along the first guide slot 121, and the second guide 230 moves along the second guide slot 122 until the battery pack 200 moves to the target position, and the locking mechanism 300 changes from the unlocking state to the locking state to fix the battery pack 200 and the mounting bracket 120. It can be understood that the first guide slot 121 and the second guide slot 122 can guide and position the first guide 220 and the second guide 230, respectively, so that the battery pack 200 is more convenient to move to the target position, and the assembly efficiency of the battery pack 200 and the vehicle body 100 is improved. At the same time, the limiting effect of the first guide slot 121 and the second guide slot 122 on the first guide 220 and the second guide 230, respectively, can ensure that the battery pack 200 is assembled in place. Moreover, the battery pack 200 is fixed on the mounting bracket 120 by the locking mechanism 300, and since a large number of operators are not required to participate, the fixing process is more convenient and rapid, and the assembly efficiency of the battery pack 200 and the vehicle body 100 is further improved.

[0063] The following will be described in detail with reference to the accompanying drawings. Figures 1 to 6 The various component structures and functions of the vehicle provided by the embodiments of the present application will be described in more detail.

[0064] In some embodiments, the locking mechanism 300 includes a first locking assembly and a second locking assembly. The first locking assembly is used to connect the first guide 220 and the first guide slot 121 when the first locking assembly is in the locking state. The second locking assembly is used to connect the second guide 230 and the second guide slot 122 when the second locking assembly is in the locking state. In this way, the first locking assembly and the second locking assembly can be used to more efficiently lock the battery pack 200 and the mounting bracket 120.

[0065] In combination with Figure 2 and Figure 4 As shown in the figure, in some embodiments, the first locking assembly includes a first motor 310 and a first connecting piece 320 connected to each other. The first motor 310 is installed on the body member 110, and the first connecting piece 320 is connected to the first motor 310. When the first motor 310 is started, the first connecting piece 320 is telescopically movable along the axial direction of the first motor 310. It should be noted that the first connecting piece 320 can be connected to the output shaft of the battery.

[0066] The first guiding groove 121 is provided with a first mounting hole 123, and the first guide 220 is provided with a second mounting hole 221 on the side facing the bottom of the first guiding groove 121. The first mounting hole 123 is opposite to the second mounting hole 221, and the end of the first connecting piece 320 away from the first motor 310 is connected to the first mounting hole 123 and the second mounting hole 221 when the first locking assembly is in the locked state. It can be understood that when the battery pack 200 moves to the target position, the first locking assembly changes from the unlocked state to the locked state, and at this time, the end of the first connecting piece 320 away from the first motor 310 extends towards the first mounting hole 123 and sequentially penetrates into the first mounting hole 123 and the second mounting hole 221, thereby fixing the first guide 220 and the second guide 230 together. It should be noted that the first mounting hole 123 and the second mounting hole 221 can be fixed to the outer wall of the first connecting piece 320 by a threaded connection.

[0067] As shown in Figure 4 some embodiments, the first guiding groove 121 includes opposite first and second groove walls 124 and 125 connected to the two sides of the bottom of the first guiding groove 121. The end of the first groove wall 124 away from the bottom is connected to a first baffle 126, and the end of the second groove wall 125 away from the bottom is connected to a second baffle 127. The first baffle 126 extends towards the second groove wall 125, and the second baffle 127 extends towards the first groove wall 124.

[0068] As shown in Figure 4 the first guide 220 includes a fixed part 222, a connecting part 223 and a clamping part 224. The two sides of the fixed part 222 are connected to the first side 211 of the housing 210 and one side of the connecting part 223, respectively, and the other side of the connecting part 223 is connected to the clamping part 224. The cross-sectional area of the clamping part 224 is greater than that of the connecting part 223. When the battery pack 200 and the mounting bracket 120 are assembled, the clamping part 224 is located in the groove of the first guiding groove 121, the inner walls of the first and second baffles 126 and 127 abut the side of the clamping part 224 away from the bottom, and the two sides of the connecting part 223 abut the ends of the first and second baffles 126 and 127. In this way, the clamping part 224 can be prevented from disengaging from the first guiding groove 121, thereby improving the stability of the connection between the first guide 220 and the first guiding groove 121, i.e., the stability of the connection between the battery pack 200 and the mounting bracket 120.

[0069] As shown in Figure 4 some embodiments, the first guide 220 is of a hollow structure, thereby achieving the effect of weight reduction and further achieving the lightweight of the battery pack 200.

[0070] It should be noted that the second locking assembly in the embodiments of the present application has the same structure as the first locking assembly, the first guide slot 121 and the second guide slot 122 have the same structure, and the first guide 220 and the second guide 230 also have the same structure. The second locking assembly fixes the second guide 230 and the second guide slot 122 together in the same principle as the first locking assembly fixing the first guide slot 121 and the second guide slot 122 together, which can be referred to the above description, and the present application will not be repeated here.

[0071] In combination Figures 1 to 5 As shown in the drawings, in another aspect, the embodiments of the present application also provide an assembly system, which comprises a transfer mechanism 400, a controller 440 and a vehicle as described in any one of the above embodiments of the present application. It should be noted that the vehicle has the same composition as the vehicle in the above embodiments of the present application, and therefore the embodiments of the present application will not be repeated here.

[0072] The transfer mechanism 400 comprises a transfer trolley 410 for carrying the battery pack 200, a first driving assembly 420 and a second driving assembly 430, which are respectively installed on the transfer trolley 410. A controller 440 is in signal connection with the first driving assembly 420, the second driving assembly 430 and the locking mechanism 300 respectively. Thus, the controller 440 and the first driving assembly 420 can transmit signals, and the controller 440 and the second driving assembly 430 can transmit signals. It should be noted that the signal connection in the embodiment of the present application can be realized by a hard wire or by wireless connection. The controller 440 is configured to control the first driving assembly 420 to drive the transfer trolley 410 to move in a first direction, and the controller 440 is further configured to control the second driving assembly 430 to drive the battery pack 200 to move in a second direction, and the controller 440 is further configured to control the locking mechanism 300 to switch between the unlocked state and the locked state, and the first direction and the second direction are perpendicular. It should be noted that one of the first direction and the second direction is parallel to the length direction of the vehicle body 100, and the other is parallel to the width direction of the vehicle body 100. When the controller 440 controls the first driving assembly 420 to drive the transfer trolley 410 to move in the first direction, the battery pack 200 on the transfer trolley 410 also moves in the first direction. Thus, the battery pack 200 can move in two perpendicular directions under the driving of the first driving assembly 420 and the second driving assembly 430, and the battery pack 200 can move in four directions of front, back, left and right, thereby improving the flexibility of the movement of the battery pack 200. It should be understood that when the battery pack 200 carried by the transfer trolley 410 moves to the target position, the locking mechanism 300 changes from the unlocked state to the locked state, so as to assemble the battery pack 200 and the vehicle body 100 together. The connection principle of the assembly process is the same as that of the connection between the first guide 220 and the second guide 230 and the first guide slot 121 and the second guide slot 122 in the above embodiment of the present application.

[0073] The assembly system provided in the embodiment of the present application can directly or indirectly move the battery pack 200 to the target position by using the controller 440, and assemble the battery pack 200 and the vehicle body 100 together. That is, the battery pack 200 can be automatically transferred and installed without the participation of personnel, which not only improves the assembly efficiency, but also ensures that the battery pack 200 is assembled in place, avoiding the problem that the assembly position of the battery pack 200 is deviated due to the operation error of personnel.

[0074] As Figure 3As shown, in some embodiments, the first drive assembly 420 includes a second motor 421, a first sprocket (not shown), a second sprocket (not shown), and a first chain (not shown). The transfer vehicle 410 includes a support plate 411, a first wheel 412 and a second wheel 413 disposed opposite each other, connected by a drive shaft. The second motor 421 is signal-connected to a controller 440, allowing the controller 440 to control the operating state of the second motor 421. The second motor 421 can be mounted on the support plate 411. The first sprocket is sleeved on the output shaft of the second motor 421 so that the first sprocket can rotate synchronously with the output shaft of the second motor 421. The second sprocket is sleeved on the drive shaft so that the drive shaft can rotate synchronously with the second sprocket, thereby allowing the first wheel 412 and the second wheel 413 to rotate synchronously with the drive shaft. The first chain meshes with both the first and second sprockets. When the second motor 421 rotates, it first drives the first sprocket to rotate, then the first chain rotates with the first sprocket, and subsequently the second sprocket rotates under the drive of the first chain. This sequentially drives the drive shaft, the first wheel 412, and the second wheel 413 to rotate, allowing the transfer vehicle 410 to move along the first direction. It should be noted that the above is only one example structure of the first drive assembly 420. Other first drive assemblies 420 capable of enabling the transfer vehicle 410 to move along the first direction can be applied in this application embodiment. This application embodiment does not list all the configurations of the first drive assembly 420.

[0075] like Figure 3 As shown, in some embodiments, the assembly system further includes a lifting mechanism 500 located on a transfer vehicle 410. The side of the lifting mechanism 500 facing away from the transfer vehicle 410 carries the battery pack 200. The lifting mechanism 500 is signal-connected to a controller 440, which controls the lifting mechanism 500 to be in a raised or lowered state, so that the height of the first guide member 220 is consistent with the height of the first guide groove 121, and the height of the second guide member 230 is consistent with the height of the second guide groove 122. This ensures that the first guide member 220 and the second guide member 230 can move along the grooves of the first guide groove 121 and the second guide groove 122, respectively. It should be understood that the distance between the mounting bracket 120 and the ground varies on different vehicles, and therefore the distance between the battery pack 200 and the mounting bracket 120 also varies. The lifting mechanism 500 allows for more flexible adjustment of the battery pack 200's position in the height direction to meet the assembly requirements of mounting brackets 120 located at different heights in different vehicles.

[0076] like Figure 3As shown, in some embodiments, the lifting mechanism 500 includes a lifting section 510 and a supporting section 520. The supporting section 520 is connected to the top of the lifting section 510 and can be used to support the battery pack 200. The lifting section 510 is mounted on the support plate 411 of the transfer vehicle 410 and is signal-connected to the controller 440 for driving the supporting section 520 closer to or further away from the support plate 411. The second drive assembly 430 includes a third motor 431 and at least one push rod 432. The housing 210 includes a third side 213, with its two ends connected to the first side 211 and the second side 212, respectively. The third motor 431 is mounted on the supporting section 520. One end of the push rod 432 is connected to the output shaft of the third motor 431. The other end of the push rod 432 is connected to the third side 213. When the third motor 431 rotates, it can drive the push rod 432 to move in a second direction, for example, towards or away from the third motor 431. The third motor 431 can be connected to the controller 440 via a signal, so that the controller 440 can control the working state of the third motor 431.

[0077] like Figure 3 As shown, in some embodiments, the side of the support portion 520 that supports the battery pack 200 is provided with multiple support portions 521 with a semi-circular cross-section. These support portions 521 extend along the direction from the first guide member 220 to the second guide member 230, with the arcuate surface of the support portion 521 facing the battery pack. The bottom surface of the battery pack 200 abuts against the support portion 521. It is understood that the support portion 521 can reduce the friction between the battery pack 200 and the support portion 520, making it easier for the push rod 432 to push the battery pack 200.

[0078] like Figure 5As shown, in some embodiments, the assembly system further includes a position sensor assembly 600, which is mounted on the transfer vehicle 410 and signal-connected to a controller 440. The controller 440 determines the position of the transfer vehicle 410 based on the position information sent by the position sensor. It should be noted that the position sensor assembly 600 may include a first sensor, a second sensor, and a third sensor, respectively signal-connected to the controller 440. The first sensor monitors the movement position of the transfer vehicle 410 along a first direction, and the controller 440 determines, based on the signal fed back from the first sensor, that the transfer vehicle 410 has moved to the assembly position along the first direction. The second sensor monitors the movement position of the battery pack 200 along a second direction, and the controller 440 determines, based on the signal fed back from the second sensor, that the battery pack 200 has moved to the target position along the second direction. The third sensor monitors the lifting height of the lifting device, and the controller 440 determines, based on the signal fed back from the third sensor, the distance between the support portion 520 of the lifting device and the support plate 411 of the transfer vehicle 410, i.e., the current lifting height of the lifting device. By cooperating with multiple sensors, the position of the battery pack 200 can be precisely adjusted, improving the accuracy of the battery pack 200 assembly position. In some embodiments, the sensor assembly 600 further includes a fourth sensor signal-connected to the controller 440. The fourth sensor is connected to a motor in the locking mechanism 300, for example, the fourth sensor is signal-connected to the first motor 310 and the motor in the second locking assembly. Based on the signal fed back by the fourth sensor, the controller 440 determines whether the first locking mechanism 300 and the second locking mechanism 300 are in a locked or unlocked state. It is understood that by setting multiple sensors, the position of the battery pack 200 can be determined more accurately, thereby assembling the battery pack 200 with the mounting bracket 120 more accurately and efficiently. It should be noted that the aforementioned multiple sensors can be position sensors.

[0079] like Figure 5 As shown, in some embodiments, the assembly system further includes an image acquisition device 700, which is signal-connected to the controller 440. The image acquisition device 700 can be mounted on the vehicle body 100 to acquire image information of the battery pack 200. This allows for the determination of whether the battery pack 200 is damaged, preventing the assembly of a damaged battery pack 200 onto the vehicle body 100 and thus ensuring the effectiveness of the battery pack 200 assembly.

[0080] like Figure 5As shown in the figure, in some embodiments, the assembly system further comprises a code scanning device 800, which is in signal connection with the controller 440. The code scanning device 800 can be installed on the vehicle body 100, and is used for scanning a target code identifier on the battery pack 200. The target code identifier is used to indicate the model of the battery pack 200, for example, can be a two-dimensional code or a bar code corresponding to the battery pack 200, and the like. Thus, the model of the battery pack 200 can be accurately identified, so as to avoid the phenomenon that the battery pack 200 is incorrectly assembled due to the mismatch between the battery pack 200 and the vehicle body 100, and ensure that the battery pack 200 matched with the vehicle body 100 is assembled.

[0081] As shown in the figure, Figure 5 As shown in the figure, in some embodiments, the assembly system further comprises a display 900, which is in signal connection with the controller 440. The display 900 has a display function, and is used to display assembly information corresponding to the assembly signal based on the assembly signal sent by the controller 440. For example, the assembly information can be the current position of the battery pack 200, the current position of the transfer trolley 410, the working state of the locking mechanism 300, and the like.

[0082] As shown in the figure, Figure 6 On the other hand, the embodiment of the present application also provides an assembly method, which is applied to the assembly system as described in any one of the above embodiments of the present application, and can be executed by the controller 440. It should be noted that the assembly method provided by the embodiment of the present application is applied to the assembly system which belongs to the same inventive concept as the assembly system provided by the above embodiment of the present application, and the components and principles of the assembly system are the same, so the embodiment of the present application will not be described here. The assembly method provided by the embodiment of the present application comprises steps 101 to 103.

[0083] In step 101, the controller 440 generates a first movement instruction based on the current position of the transfer trolley 410 and the to-be-assembled position.

[0084] The first movement instruction is used to instruct the first driving assembly 420 to drive the transfer trolley 410 to move to the to-be-assembled position in the first direction. It can be understood that when the transfer trolley 410 moves, the battery pack 200 placed on the transfer trolley 410 also moves synchronously with the transfer trolley 410. In some embodiments, the first movement instruction comprises a first movement distance. The first driving assembly 420 drives the transfer trolley 410 to move in the first direction by the first movement distance to the to-be-assembled position based on the first movement instruction.

[0085] In some embodiments, the controller 440 sends the first movement instruction to the second motor 421 in the first driving assembly 420, and the second motor 421 drives the transfer trolley 410 to move to the to-be-assembled position in the first direction in response to receiving the first movement instruction.

[0086] In step 102, the controller 440 generates a second movement instruction in response to the transfer vehicle 410 reaching the position to be assembled.

[0087] The second movement instruction is used to instruct the second driving assembly 430 to drive the battery pack 200 to move in a second direction, so that the battery pack 200 moves to a target position, and the second direction is perpendicular to the first direction. In some embodiments, the second movement instruction includes a second movement distance. The second driving assembly 430 drives the battery pack 200 to move in the second direction by the second distance to the target position based on the second movement instruction. It can be understood that the second driving assembly 430 drives the battery pack 200 to move in the second direction, that is, the second driving assembly 430 drives the first guide 220 to move in the first guide slot 121, and drives the second guide 230 to move in the second guide slot 122.

[0088] In some embodiments, the controller 440 sends the second movement instruction to the third motor 431 in the second driving assembly 430. The third motor 431 drives the battery pack 200 to move in the second direction to the target position in response to receiving the second movement instruction.

[0089] In step 103, the controller 440 generates a locking instruction in response to the battery pack 200 moving to the target position.

[0090] The locking instruction is used to control the locking mechanism 300 to be in a locked state. It should be understood that when the locking mechanism 300 is in the locked state, the battery pack 200 and the mounting bracket 120 are fixed together by the locking mechanism 300.

[0091] In some embodiments, the controller 440 sends the locking instruction to the motor in the locking mechanism 300, and the motor in the locking mechanism 300 changes from an unlocked state to a locked state in response to receiving the locking instruction. It should be noted that the controller 440 can determine that the locking mechanism 300 is in the locked state based on a signal fed back by a fourth sensor connected to the motor in the locking mechanism 300. The signal fed back by the fourth sensor may, for example, indicate the rotation direction and the number of rotations of the motor in the locking mechanism 300.

[0092] It should be noted that the operation principles of the first driving assembly 420, the second driving assembly 430 and the locking mechanism 300 involved in the assembly method provided by the embodiments of the present application are the same as the operation principles of the first driving assembly 420, the second driving assembly 430 and the locking mechanism 300 in the assembly system provided by the embodiments of the present application, and therefore the embodiments of the present application will not be described here.

[0093] By using the assembling method provided in the embodiment of the present application, the battery pack 200 can be automatically moved in two directions perpendicular to each other in a flexible manner, and when the battery pack 200 moves to the target position, the battery pack 200 can be fixed on the mounting bracket 120 by using the locking mechanism 300. Thus, an automatic assembling process without the participation of a large number of personnel is realized, which not only saves a large amount of manpower and reduces costs, but also improves the assembling efficiency of the battery pack 200 and the vehicle body 100.

[0094] As shown in Figure 7 On the other hand, the embodiment of the present application also provides an assembling method, which is applied to the assembling system as described in any one of the above embodiments of the present application. It should be noted that the assembling system to which the assembling method provided in the embodiment of the present application belongs to the same inventive concept as the assembling system provided in the above embodiments of the present application, and the components and principles of the assembling system are the same, so the embodiment of the present application will not be described here. The assembling method can be executed by the controller 440. The assembling method provided in the embodiment of the present application includes steps 201 to 208.

[0095] In step 201, the controller 440 generates a first movement instruction based on the current position of the transfer trolley 410 and the position to be assembled.

[0096] The first movement instruction is used to instruct the first driving assembly 420 to drive the transfer trolley 410 to move to the position to be assembled in the first direction. It should be noted that step 201 is the same as step 101, so the embodiment of the present application will not be described here.

[0097] In some embodiments, the controller 440 obtains the current position of the transfer trolley 410 and the position to be assembled based on a start signal, wherein the start signal can be generated by a start control in response to a first trigger operation of the start control, and the start control is in signal connection with the controller 440. The first trigger operation can be a pressing operation of the start control by the operator.

[0098] In step 202, the controller 440 obtains a target distance in response to the transfer trolley 410 reaching the position to be assembled.

[0099] The target distance is the distance between the first guide 220 and the first guide groove 121 in the height direction.

[0100] In step 203, the controller 440 generates a lifting instruction based on the target distance.

[0101] The lifting instruction is used to instruct the lifting mechanism 500 to ascend or descend by a target distance. In some embodiments, the controller 440 sends the lifting instruction to the lifting part 510, and the lifting part 510 drives the bearing part 520 to ascend or descend by the target distance relative to the bearing plate 411 based on the lifting instruction, so that the first guide 220 and the second guide 230 on both sides of the battery pack 200 on the bearing part 520 reach the height consistent with the first guide groove 121 and the second guide groove 122 respectively, ensuring that the first guide 220 can move in the first guide groove 121 and the second guide 230 can move in the second guide groove 122. It should be noted that the distance between the mounting bracket 120 on different vehicles and the ground is different, and thus the distance between the battery pack 200 and the mounting bracket 120 is also different. By cooperating the controller 440 and the lifting mechanism 500, the distance between the battery pack 200 and the mounting bracket 120 can be adjusted to meet the needs of the mounting bracket 120 of different heights, ensuring efficient and accurate assembly of the battery pack 200.

[0102] In some embodiments, the third sensor generates a lifting position signal in response to the lifting part 510 having ascended or descended by the target distance, and sends the lifting position signal to the controller 440. The controller 440 controls the lifting part to stop working in response to receiving the lifting position signal. It can be understood that by setting the third sensor, the working state of the lifting part can be controlled more timely, avoiding excessive ascent or descent of the lifting part.

[0103] In step 204, the controller 440 acquires the image information of the battery pack 200 in response to the transfer trolley 410 reaching the assembly position.

[0104] In some embodiments, the first sensor sends a first position signal to the controller 440 in response to the transfer trolley 410 reaching the assembly position. The controller 440 determines that the transfer trolley 410 reaches the assembly position in response to receiving the first position signal. It can be understood that the first position signal can more accurately reflect the position of the transfer trolley 410, ensuring that the transfer trolley 410 is transported in place.

[0105] In some embodiments, the controller 440 generates an image acquisition instruction and sends the image acquisition instruction to the image acquisition device 700 in response to the transfer trolley 410 reaching the assembly position. The image acquisition device 700 acquires the image information of the battery pack 200 in response to receiving the image acquisition instruction, and sends the image information to the controller 440. The image information refers to the appearance image of the battery pack 200.

[0106] In step 205, the controller 440 determines that the battery pack 200 is in an undamaged state based on the image information of the battery pack 200, and generates a second moving instruction.

[0107] The second moving instruction is used to instruct the second driving assembly 430 to drive the battery pack 200 to move in a second direction, so that the battery pack 200 moves to a target position, and the second direction is perpendicular to the first direction. It should be understood that when the transfer trolley 410 moves in the first direction, the battery pack 200 located on the transfer trolley 410 also moves synchronously with the transfer trolley 410. By controlling the battery pack 200 to move in the first direction and the second direction in turn, the battery pack 200 can be flexibly moved in four directions of front, back, left and right. It should be noted that the battery pack 200 in the undamaged state means that the outer surface of the battery pack 200 does not have missing parts and is not deformed by extrusion. The method provided in the application can avoid the situation that the damaged battery pack 200 caused by collision during the transfer process is still assembled, that is, the damaged battery pack 200 is assembled on the vehicle body 100 to affect the normal use of the vehicle, by using the controller 440 to determine the appearance image of the battery pack 200 and only when it is undamaged to move to the next step.

[0108] In step 206, the controller 440 identifies the battery pack 200 in response to the transfer trolley 410 reaching the position to be assembled, to obtain the target model corresponding to the battery pack 200.

[0109] It should be noted that the battery pack 200 generally has a target code identifier for indicating the model of the battery pack 200. In some embodiments, the controller 440 generates an identification instruction in response to the transfer trolley 410 reaching the position to be assembled, and sends the identification instruction to the code scanning device 800. The code scanning device 800 identifies the target code identifier of the battery pack 200 located at the position to be assembled in response to receiving the identification instruction, obtains the target model, and sends the target model to the controller 440, wherein the target model is the model corresponding to the target code identifier.

[0110] In step 207, the controller 440 determines that the battery pack 200 meets the assembly condition based on the target model and the matching model set, and generates a second moving instruction.

[0111] The matching model set includes at least one to-be-matched model, and the assembly condition is that the target model is the same as any to-be-matched model. It should be noted that the controller 440 pre-stores the matching model set, and the to-be-matched model in the matching model set corresponds to the battery pack 200 that can be assembled to the current vehicle body 100 to meet the use demand of the vehicle. It should be understood that this method can ensure that the battery pack 200 meeting the assembly condition is assembled to the mounting bracket 120, and avoid that other battery packs 200 not meeting the use demand of the vehicle are mistakenly assembled to the mounting bracket 120 to affect the normal use of the vehicle. Thus, the correctness of the assembly of the battery pack 200 is ensured on the basis of improving the assembly efficiency of the battery pack 200.

[0112] It should be noted that the method of steps 204 to 205 and the method of steps 206 to 207 are two ways to achieve that the controller 440 generates the second moving instruction in response to the transfer trolley 410 reaching the position to be assembled. One of the two methods can be executed, or the two methods can be executed respectively, and the execution sequence of the two methods is not limited in the embodiments of the present application.

[0113] In step 208, the controller 440 generates a locking instruction in response to the battery pack 200 moving to the target position.

[0114] The locking instruction is used to control the locking mechanism 300 to be in the locking state. It can be understood that when the locking mechanism 300 is in the locking state, the first guide 220 has been fixedly connected with the first guide groove 121, and the second guide 230 has been fixedly connected with the second guide groove 122, that is, the battery pack 200 and the mounting bracket 120 are in a fixedly connected state, and at this time the battery pack 200 has been assembled.

[0115] In some embodiments, the second sensor sends a second position signal to the controller 440 in response to the battery pack 200 moving to the target position. The controller 440 determines that the battery pack 200 moves to the target position in response to receiving the second position signal, and controls the second driving assembly 430 to stop working. That is, when the battery pack 200 moves to the target position, the controller 440 can control the second driving assembly 430 to stop pushing the battery pack 200 in time to avoid the battery pack 200 from moving too much.

[0116] In some embodiments, the fourth sensor sends a third position signal to the controller 440 in response to the locking mechanism 300 being in the locking state. The controller 440 controls the locking mechanism 300 to stop working in response to receiving the third position signal. Thus, energy consumption is avoided due to the locking mechanism 300 still being in the working state when it is locked in place.

[0117] In some embodiments, the controller 440 sends an assembly signal to the display 900. The display 900 displays assembly information corresponding to the assembly signal based on the assembly signal. For example, the assembly signal can be the signal fed back by each sensor in the sensor assembly 600 to the controller 440. The assembly information can be the current position of the battery pack 200, the current position of the transfer trolley 410, the working state of the locking mechanism 300, and other assembly information determined based on the assembly signal, so as to facilitate the staff to know the current assembly progress of the battery pack 200 in time.

[0118] In some embodiments, the controller 440 generates a fault signal in response to not receiving the assembling signal within a preset time, and sends the fault signal to the display 900. The display 900 generates and displays fault prompt information corresponding to the fault signal in response to the fault signal. Thus, the worker can know that there may be a fault in a component of the assembly system by seeing the fault prompt information, and then can troubleshoot and solve the fault in a timely manner to ensure the normal operation of the assembly system.

[0119] In some embodiments, the controller 440 generates a stop instruction based on the stop signal, where the stop instruction is used to instruct the first driving assembly 420, the second driving assembly 430, the locking mechanism 300, and the lifting mechanism 500 to be in a stop working state. It should be noted that the stop signal can be generated by the stop control in response to a second trigger operation of the stop control, and the stop control is in signal connection with the controller 440. The second trigger operation can be a pressing operation of the stop control by the operator. In this way, when a fault occurs or the transfer is completed, the operator can press the stop control in a timely manner to make each mechanism in a stop working state, and then can troubleshoot in a timely manner or avoid each mechanism consuming too much energy in an unnecessary working state for a long time. It should be noted that the start control and the stop control in the embodiments of the present application can be physical buttons or controls displayed on the display 900.

[0120] In some embodiments, the controller 440 generates a recovery instruction in response to the locking mechanism 300 being in the locked state, where the recovery instruction is used to instruct the second driving assembly 430, the lifting mechanism 500, and the first driving assembly 420 to retreat to the corresponding initial positions in sequence. That is, the third motor 431 drives the push rod 432 to retreat to the corresponding first initial position when both the first guide 220 and the second guide 230 on both sides of the battery pack 200 are not clamped into the first guide slot 121 and the second guide slot 122 in response to receiving the recovery instruction. Then the lifting part 510 drives the carrying part 520 to rise or fall to the second initial position corresponding to the assembling position of the battery pack 200 in response to receiving the recovery instruction and the push rod 432 having retreated to the first initial position. Finally, the second motor 421 drives the transfer trolley 410 to retreat to the starting position of loading the battery pack 200 in response to receiving the recovery instruction and the carrying part 520 being in the second initial position. Thus, the transfer trolley 410 can continue to carry the battery pack 200 and perform the above steps to install the next battery pack 200 on the corresponding vehicle body 100.

[0121] In the present application, the terms "first" and "second" are only for descriptive purposes, and cannot be understood as indicating or implying relative importance. The term "a plurality of" means two or more, unless otherwise explicitly limited.

[0123] It is understood that the application is not limited to the precise construction described in the specification above and shown in the drawings, and that various modifications and changes can be made by those skilled in the art without departing from the scope of the application.
