Technical Field

[0001] This application relates to the field of chassis battery swapping technology, and in particular to a first locking component for chassis battery swapping, a locking mechanism for chassis battery swapping, a chassis, and a vehicle. Background Technology

[0002] In recent years, new energy vehicles have experienced rapid development. Among these developments, considering the long charging times and difficult battery maintenance associated with new energy vehicles, battery-swapping models using fast-swap batteries have been introduced.

[0003] In related technologies, the locking components for chassis battery swapping installed on the vehicle frame have a complex structure, and the time required to complete the unlocking and locking actions is long, resulting in low battery swapping efficiency. Furthermore, dust and other debris can easily enter the battery device through the mounting holes on the vehicle frame, affecting the battery device's lifespan. Utility Model Content

[0004] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a first locking assembly for chassis battery swapping. This first locking assembly helps improve battery swapping efficiency and reduces the risk of dust and other debris entering the battery device.

[0005] The first objective of this application is to provide a first locking component for chassis battery swapping.

[0006] The second objective of this application is to provide a locking mechanism for chassis battery swapping.

[0007] The third objective of this application is to propose a chassis.

[0008] The fourth objective of this application is to propose a vehicle.

[0009] In a first aspect, this application proposes a first locking assembly for chassis battery swapping. The first locking assembly is disposed on the vehicle frame and used for mounting a battery device. The battery device has a second locking assembly, which includes a locking rod. The vehicle frame has a mounting hole, and the locking rod is reciprocating relative to the mounting hole. The first locking assembly includes a latching member disposed on the vehicle frame and movable relative to the vehicle frame. The first locking assembly has an unlocked state and a locked state. In the unlocked state, the latching member avoids the mounting hole to avoid the movement of the locking rod. In the locked state, the latching member at least blocks the mounting hole and cooperates with the locking rod extending out of the mounting hole to limit the movement of the locking rod.

[0010] In the above technical solution, by making the latching component movable relative to the vehicle frame, the latching component can selectively avoid or at least block the mounting hole. When the latching component at least blocks the mounting hole, it can cooperate with the locking rod extending from the mounting hole to limit the movement of the locking rod. In this process, there is no need to drive the locking rod, which helps to reduce the complexity of unlocking and locking actions when mounting or dismounting the battery device, thereby improving battery swapping efficiency. In addition, since the latching component can at least block the mounting hole, it helps to reduce the risk of dust or rainwater and other debris falling into the battery device through the mounting hole.

[0011] According to some embodiments of this application, the latch is reciprocating relative to the frame to allow the first locking assembly to switch between the unlocked state and the locked state.

[0012] In the above technical solution, by enabling the card connector to reciprocate relative to the vehicle frame, it is beneficial to simplify the power transmission path used to drive the card connector to move, thereby improving the unlocking and locking efficiency of the first locking component, which in turn is beneficial to further improve the battery swapping efficiency, and also helps to reduce the structural complexity of the first locking component and reduce the production cost of the first locking component.

[0013] According to some embodiments of this application, the first locking assembly includes a rotating member that cooperates with the latching member to drive the latching member to move.

[0014] In the above technical solution, by setting a rotating component, the reciprocating movement of the locking component can be realized, and the structure of the first locking component can be simplified, thereby reducing the production cost of the first locking component.

[0015] According to some embodiments of this application, there are multiple snap-fit ​​members, and the rotating member cooperates with each of the multiple snap-fit ​​members. The rotating member rotates to drive each snap-fit ​​member to move, and each snap-fit ​​member is used to block or avoid the corresponding hanging hole.

[0016] In the above technical solution, by setting multiple locking components and having the rotating component cooperate with multiple locking components respectively, it is beneficial to further simplify the structure of the first locking component, reduce the production cost of the first locking component, and reduce the complexity of the unlocking and locking actions of the first locking component, thereby improving the locking and unlocking efficiency of the first locking component and thus improving the battery swapping efficiency.

[0017] According to some embodiments of this application, the rotating member includes a gear and a drive shaft, the gear being disposed on the drive shaft; the snap-fit ​​member includes a rack portion and a blocking portion, the rotating member engaging with the rack portions of the two snap-fit ​​members respectively to drive the two snap-fit ​​members to move towards each other or away from each other, and in the locked state, at least one blocking portion is provided below the locking rod.

[0018] In the above technical solution, by constructing the rotating part and the locking part to cooperate in a gear and rack manner, it is beneficial to improve the transmission accuracy of the rotating part and the locking part, and also beneficial to improve the transmission efficiency of the rotating part and the locking part. At the same time, it is beneficial to improve the compactness of the cooperation between the rotating part and the locking part, reduce the space required to arrange the first locking component, and by setting a blocking part on the locking part, it is possible for the locking part to limit the locking rod.

[0019] According to some embodiments of this application, in the locked state, each of the locking rods has two blocking portions of the latching members below it, and the two blocking portions are located on both sides of the locking rod in the direction of movement of the latching members.

[0020] In the above technical solution, in the locked state, by providing two blocking parts of the latching member below each locking rod, and placing the two blocking parts on both sides of the locking rod in the direction of movement of the latching member, it is beneficial to reduce the risk of the locking rod shifting or shaking in the locked state, thereby improving the stability of the battery device mounting.

[0021] According to some embodiments of this application, each of the blocking portions is provided with a slot, and in the locked state, a portion of the locking rod is located within the slot.

[0022] In the above technical solution, by providing a slot for each blocking part, and in the locked state, a part of the locking rod is located in the slot, so that the blocking part can clamp the locking rod, which helps to reduce the risk of the locking rod shaking, thereby reducing the risk of the battery device shaking when mounted on the vehicle frame and improving the mounting stability of the battery device.

[0023] According to some embodiments of this application, both the locking rod and the blocking portion have mating bevels at their ends facing each other's sidewalls.

[0024] In the above technical solution, by providing a mating inclined surface at the ends of the locking rod and the blocking part facing each other, the locking rod is guided even when there is a positional deviation between the locking rod and the blocking part in the vertical direction, thereby reducing the risk of damage to the blocking part and the locking rod during the mating process due to the positional deviation between the locking rod and the blocking part.

[0025] According to some embodiments of this application, the drive shaft is fitted with a ball bearing.

[0026] In the above technical solution, by installing a ball bearing around the drive shaft, the ball bearing can provide stable support for the drive shaft and help reduce the impact of frictional resistance on the drive shaft, improve the smoothness of the drive shaft rotation, and since the ball bearing has a certain elasticity and self-aligning ability, when there is a positional deviation in the drive shaft, the ball bearing can compensate for the error, so as to facilitate the insertion and engagement of the drive shaft and the transmission rod, and help improve the success rate of the insertion and engagement of the drive shaft and the transmission rod.

[0027] According to some embodiments of this application, the first locking assembly further includes a pressure plate placed on the side of the ball bearing opposite to the frame and in contact with the ball bearing to limit the displacement of the ball bearing.

[0028] In the above technical solution, by setting a pressure plate that contacts and cooperates with the ball bearing on the side of the ball bearing away from the frame, the displacement of the ball bearing is restricted, the displacement of the ball bearing caused by the force acting on the side away from the frame is reduced, the assembly reliability of the ball bearing is improved, and the wear between the ball bearing and the drive shaft is reduced.

[0029] According to some embodiments of this application, the first locking component further includes a guide for guiding the movement of the latching member.

[0030] In the above technical solution, by setting a guide, the locking component can move along a specific trajectory, which helps to improve the accuracy of the locking component's movement, thereby improving the efficiency of the locking component in locking and unlocking the locking rod.

[0031] According to some embodiments of this application, the first locking component further includes a bracket base, the bracket base having a through hole corresponding to the hanging hole, and the first locking component being disposed on the bracket base.

[0032] In the above technical solution, by setting a support base, it is possible to achieve modular assembly of the first locking component and the support base, thereby improving the production and assembly efficiency of the locking mechanism.

[0033] Secondly, this application proposes a locking mechanism for chassis battery swapping, comprising: a first locking component, the first locking component being the aforementioned first locking component, the first locking component being disposed on the vehicle frame; and a second locking component, the second locking component being located on the battery device, the second locking component including a locking rod, wherein in the unlocked state, the latching member avoids the hanging hole to avoid the movement stroke of the locking rod, and in the locked state, the latching member at least blocks the hanging hole and cooperates with the locking rod extending out of the hanging hole to limit the movement stroke of the locking rod.

[0034] In the above technical solution, by making the latching component movable relative to the vehicle frame, the latching component can selectively avoid or at least block the mounting hole. When the latching component at least blocks the mounting hole, it can cooperate with the locking rod extending from the mounting hole to limit the movement of the locking rod. In this process, there is no need to drive the locking rod, which helps to reduce the complexity of unlocking and locking actions when mounting or dismounting the battery device, thereby improving battery swapping efficiency. In addition, since the latching component can at least block the mounting hole, it helps to reduce the risk of dust or rainwater and other debris falling into the battery device through the mounting hole.

[0035] According to some embodiments of this application, there are multiple locking rods, each of which has a locking protrusion at its top. In the locked state, at least one latching member is provided below each locking protrusion to limit its travel. In the unlocked state, the latching member avoids the travel of the locking rod.

[0036] In the above technical solution, by setting multiple locking rods, it is beneficial to improve the stability of battery device mounting and reduce the risk of battery device falling off the vehicle frame. By setting a locking protrusion on the top of each locking rod, it is convenient for the latching component to cooperate with the locking rod, thereby facilitating the latching component to limit the movement stroke of the locking rod.

[0037] According to some embodiments of this application, the first locking assembly includes a rotating member that cooperates with the latching member to drive the latching member to move; the second locking assembly includes a transmission rod that cooperates with the rotating member to drive the rotating member to rotate.

[0038] In the above technical solution, by setting up mutually cooperating transmission rods and rotating parts, power can be transmitted to the locking parts, thereby facilitating the movement of the locking parts.

[0039] According to some embodiments of this application, the rotating member includes a drive shaft that cooperates with the transmission rod, and the drive shaft and the transmission rod are plugged into each other.

[0040] In the above technical solution, the drive shaft and the transmission rod are plugged into each other to facilitate the positioning and installation of the drive shaft and the transmission rod, thereby improving the convenience of production and assembly of the locking mechanism and thus improving the production efficiency of the locking mechanism.

[0041] According to some embodiments of this application, the transmission rod is provided with a top-open spline groove, and at least a portion of the drive shaft is formed as a spline, the spline being located within the spline groove.

[0042] In the above technical solution, by setting a top-open spline groove on the transmission rod and forming at least a part of the drive shaft as a spline, the transmission rod and the drive shaft can form a spline insertion fit, which helps to reduce the risk of slippage between the drive shaft and the transmission rod, improve the effect and efficiency of power transmission between the transmission rod and the drive shaft, and facilitate the disassembly and maintenance of the transmission rod and the drive shaft.

[0043] According to some embodiments of this application, the top of the spline groove is provided with a guide surface that extends obliquely toward the interior of the spline groove.

[0044] In the above technical solution, by setting a guide surface at the top of the spline groove that extends inward toward the spline groove, the spline is guided and positioned during the spline insertion into the spline groove, which helps to improve the convenience of the insertion and engagement of the drive shaft and the transmission rod.

[0045] According to some embodiments of this application, the second locking assembly further includes a check mechanism that cooperates with the transmission rod. The check mechanism has a check state and a rotation state. In the check state, the rotational freedom of the transmission rod is restricted, and in the rotational state, the transmission rod can be driven to rotate.

[0046] In the above technical solution, by setting a check mechanism, the check mechanism can restrict the rotational freedom of the transmission rod in the check state, thereby restricting the position of the latching member and improving the stability of the latching member in the locked state. This helps to reduce the risk of the locking protrusion and the latching member disengaging, and further helps to reduce the risk of the battery device falling off. When the check mechanism is in the rotating state, the transmission rod can be driven to rotate to adjust the position of the latching member, thereby facilitating the release of the latching member from the limiting engagement state with the locking protrusion.

[0047] According to some embodiments of this application, the check mechanism includes: a fixed seat adapted to be fixed to the battery device; a mating member that engages with the transmission rod to drive the transmission rod to rotate synchronously; and a check member that engages with the mating member and is movably engaged with the fixed seat. In the check state, the check member engages with the fixed seat to restrict the rotation of the mating member, and in the rotation state, the check member disengages from the fixed seat to drive the mating member to rotate synchronously.

[0048] In the above technical solution, by setting a check valve and a mating part, the check valve and the mating part are mated, and the check valve is selectively mated with the fixed seat, so as to switch the working state of the check valve mechanism by switching the mating state of the check valve and the fixed seat, thereby facilitating the adjustment of the limiting effect of the check valve mechanism on the transmission rod.

[0049] According to some embodiments of this application, in the check state, the check member and the fixed seat are engaged, and the check member is movable relative to the engaging member to switch to the rotation state.

[0050] In the above technical solution, since the fixing seat is fixed to the battery device, in the check state, by engaging the check member with the fixing seat, the rotational freedom of the check member is restricted, thereby achieving the purpose of restricting the rotational freedom of the mating member. By making the check member movable relative to the mating member, it is convenient to release the engagement state between the check member and the fixing seat, thereby facilitating the release of the restriction on the rotational freedom of the check member, and thus facilitating the restoration of the rotational freedom of the mating member.

[0051] According to some embodiments of this application, the mating component and the transmission rod are plugged into each other; the locking mechanism further includes an anti-loosening component, which is inserted into the mating component and the transmission rod respectively.

[0052] In the above technical solution, by inserting the mating parts into the transmission rod, the positioning and assembly of the mating parts and the transmission rod are facilitated. By setting anti-loosening parts, the reliability of the mating parts and the transmission rod is improved, and the risk of the power transmission effect being affected due to loosening of the mating parts and the transmission rod is reduced.

[0053] Thirdly, this application proposes a chassis comprising: a frame having mounting holes; a battery assembly replaceably mounted on the frame; and a locking mechanism, wherein a first locking component is mounted on the frame, a second locking component is mounted on the battery assembly, a locking rod passes through the mounting holes such that a locking protrusion is positioned above the mounting holes, and a snap-fit ​​component switches to the locked state to be positioned below the locking protrusion to position the battery assembly.

[0054] The chassis has the same advantages as the aforementioned locking mechanism, which will not be elaborated here.

[0055] According to some embodiments of this application, the battery device includes a battery housing, the locking rod includes a fixed rod and a lock head that are fixedly connected, the fixed rod is fixed to the housing, and the lock head extends out of the battery housing and is provided with the locking protrusion.

[0056] In the above technical solution, a fixing rod is provided to fix the lock head to the battery box, and to make it easy for the locking protrusion to be suspended above the battery box, so that the locking protrusion can pass through the hanging hole and cooperate with the snap-fit.

[0057] According to some embodiments of this application, the battery device is provided with a receiving groove, and the locking rod is provided with a stop protrusion, which abuts against the bottom wall of the receiving groove.

[0058] In the above technical solution, by setting a receiving groove on the battery device and setting a stop protrusion on the locking rod, the locking rod and the battery device are positioned so that the locking protrusion can be suspended above the battery box, thereby facilitating the locking protrusion to pass through the hanging hole and cooperate with the snap-fit ​​component.

[0059] Fourthly, this application proposes a vehicle comprising the aforementioned chassis.

[0060] The vehicle described above shares the same advantages as the chassis mentioned above, and will not be elaborated upon here.

[0064] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly 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.

[0066] In this application, the reference to "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment that is mutually exclusive with other embodiments.

For example, they can refer to direct connection or indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0068] In this application, the term "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, in this application, the character " / " generally indicates that the preceding and following related objects have an "or" relationship.

[0069] In the embodiments of this application, the same reference numerals denote the same components, and for the sake of brevity, detailed descriptions of the same components are omitted in different embodiments. It should be understood that the thickness, length, width, and other dimensions of various components in the embodiments of this application shown in the accompanying drawings, as well as the overall thickness, length, width, and other dimensions of the integrated device, are merely illustrative and should not constitute any limitation on this application.

[0070] In this application, "multiple" means two or more (including two).

[0071] The battery device mentioned in the embodiments of this application refers to a single physical module comprising multiple battery cells to provide higher voltage and capacity. The battery device includes a housing for encapsulating multiple battery cells or multiple battery modules, the housing preventing liquids or other foreign matter from affecting the charging or discharging of the battery cells.

[0072] In recent years, new energy vehicles have experienced rapid development, with their driving range now comparable to that of traditional gasoline vehicles. However, considering the long charging times and difficult battery maintenance associated with new energy vehicles, battery-swapping models using fast-swap batteries have been introduced.

[0073] In related technologies, the locking mechanism for chassis battery swapping installed on the vehicle frame has a complex structure, and the time required to complete the unlocking and locking actions is long, resulting in low battery swapping efficiency. Furthermore, it is easy for dust and other debris to enter the battery device through the mounting holes on the vehicle frame, affecting the battery device's lifespan.

[0074] Based on the above considerations, in order to improve battery swapping efficiency and reduce the risk of dust and other debris entering the battery device, a first locking assembly for chassis battery swapping is proposed. The first locking assembly is located on the vehicle frame and is used to mount the battery device. The battery device has a second locking assembly, which includes a locking rod. The vehicle frame has a mounting hole, and the locking rod can reciprocate relative to the mounting hole. The first locking assembly includes a latching member, which is located on the vehicle frame and movable relative to the vehicle frame. The first locking assembly has an unlocked state and a locked state. In the unlocked state, the latching member avoids the mounting hole to avoid the movement of the locking rod. In the locked state, the latching member at least blocks the mounting hole and cooperates with the locking rod extending out of the mounting hole to limit the movement of the locking rod.

[0075] In the above technical solution, by making the latching component movable relative to the vehicle frame, the latching component can selectively avoid or at least block the mounting hole. When the latching component at least blocks the mounting hole, it can cooperate with the locking rod extending from the mounting hole to limit the movement of the locking rod. In this process, there is no need to drive the locking rod, which helps to reduce the complexity of unlocking and locking actions when mounting or dismounting the battery device, thereby improving battery swapping efficiency. In addition, since the latching component can at least block the mounting hole, it helps to reduce the risk of dust or rainwater and other debris falling into the battery device through the mounting hole.

[0076] Please refer to Figure 1 Vehicle 1000 can be a new energy vehicle, such as a pure electric vehicle, a hybrid electric vehicle, or a range-extended electric vehicle. Vehicle 1000 includes a chassis 200, which serves as the frame supporting the entire vehicle body. Battery device 220 provides power to vehicle 1000; for example, it can act as the operating power source. Vehicle 1000 may also include a controller and a motor. The controller controls the battery to supply power to the motor, for example, to meet the power needs of starting, navigation, and driving. In some embodiments of this application, battery device 220 can not only serve as the operating power source for vehicle 1000 but also as its drive power source, replacing or partially replacing fuel or natural gas to provide driving power to vehicle 1000.

[0077] Combination Figures 2 to 6 as well as Figure 10 and Figure 11In some embodiments of this application, a first locking assembly 110 for chassis battery swapping is disposed on the vehicle frame and used to mount a battery device 220. The battery device 220 has a second locking assembly, which includes a locking rod 122. The vehicle frame has a mounting hole 211, and the locking rod 122 can reciprocate relative to the mounting hole 211. The first locking assembly 110 includes a latching member 112, which is disposed on the vehicle frame and movable relative to the vehicle frame. The first locking assembly 110 has an unlocked state and a locked state. In the unlocked state, the latching member 112 avoids the mounting hole 211 to avoid the movement of the locking rod 122. In the locked state, the latching member 112 at least blocks the mounting hole 211 and cooperates with the locking rod 122 extending out of the mounting hole 211 to limit the movement of the locking rod 122.

[0078] In the above technical solution, by making the latching member 112 movable relative to the vehicle frame, the latching member 112 can selectively avoid or at least block the mounting hole 211. When the latching member 112 at least blocks the mounting hole 211, the latching member 112 can cooperate with the locking rod 122 extending out of the mounting hole 211 to limit the movement of the locking rod 122. In this process, there is no need to drive the locking rod, which helps to reduce the complexity of the unlocking and locking actions when mounting or dismounting the battery device 220, thereby improving the battery swapping efficiency. In addition, since the latching member 112 can at least block the mounting hole 211, it helps to reduce the risk of dust or rainwater and other debris falling into the battery device 220 through the mounting hole 211. Please combine Figures 2 to 6 For example, the locking bar 122 provided on the battery device 220 can pass through the mounting hole 211 and reciprocate relative to the mounting hole 211. Before battery swapping, the battery device 220 is mounted on the vehicle frame. At this time, the locking bar 122 extends out of the mounting hole 211, and the latching member 112 moves to a position that at least blocks the mounting hole 211. The latching member 112 can engage with at least a portion of the locking bar 122 extending from the mounting hole 211 to limit the travel of the locking bar 122. For example, before battery swapping, the locking bar... The top of the locking rod 122 extends out of the hanging hole 211. At least a portion of the locking member 112 can be located at a position opposite to the hanging hole 211 in the vertical direction and can be engaged with the top of the locking rod 122 in the vertical direction to limit the movement of the locking rod 122 and improve the stability of the battery device 220 when it is mounted on the vehicle 1000. Since the locking member 112 blocks at least a portion of the hanging hole 211, the risk of dust or rainwater and other debris falling into the battery device 220 through the hanging hole 211 can be effectively reduced.

[0079] Combination Figure 10 and Figure 11When a battery swap is required, the latching member 112 moves to a position vertically offset from the mounting hole 211 to avoid it. Under the weight of the battery device 220, the locking rod 122 tends to move downwards vertically. Since the latching member 112 avoids the mounting hole 211, it does not interfere with the movement of the locking rod 122. Therefore, the locking rod 122 can be driven downwards and disengaged from the mounting hole 211 under the weight of the battery device 220, allowing the battery device 220 to move relative to the frame, facilitating its removal.

[0080] Combination Figures 2 to 6 After the original battery device 220 mounted on the frame is removed, the new battery device 220 can be positioned with the frame. At this time, the locking rod 122 can pass through the mounting hole 211 from bottom to top, and the top of the locking rod 122 can extend out of the mounting hole 211. The latching member 112 moves to a position that at least blocks the mounting hole 211. The latching member 112 can cooperate with the locking rod 122 extending out of the mounting hole 211 to limit the movement of the locking rod 122.

[0081] Therefore, during the battery swapping process, the locking lever 122 on the battery device 220 does not need to be driven, which helps to reduce the complexity of the unlocking and locking actions when mounting or dismounting the battery device 220, thereby improving the battery swapping efficiency.

[0082] Combination Figures 2 to 6 In some embodiments of this application, the latch 112 is reciprocating relative to the frame so that the first locking assembly 110 switches between an unlocked state and a locked state.

[0083] In the above technical solution, by enabling the card connector 112 to reciprocate relative to the vehicle frame, it is beneficial to simplify the power transmission path for driving the card connector 112 to move, thereby improving the efficiency of unlocking and locking of the first locking component 110, which in turn is beneficial to further improve the battery swapping efficiency, and also helps to reduce the structural complexity of the first locking component 110 and reduce the production cost of the first locking component 110.

[0084] For example, combined Figure 10 and Figure 11When a battery swap is required, the latching member 112 can be moved (for example, the latching member 112 can move forward relative to the frame) to a position that is vertically offset from the mounting hole 211 to avoid the mounting hole 211. Under the weight of the battery device 220, the locking rod 122 tends to move downward in the vertical direction. Since the latching member 112 avoids the mounting hole 211 at this time, the latching member 112 will not interfere with the movement of the locking rod 122. Therefore, the locking rod 122 can be driven downward under the weight of the battery device 220 and disengage from the mounting hole 211, so that the battery device 220 can move relative to the frame, which facilitates the removal of the battery device 220.

[0085] Combination Figures 2 to 6 After the original battery device 220 mounted on the frame is removed, the new battery device 220 can be positioned with the frame. At this time, the locking rod 122 can pass through the mounting hole 211 from bottom to top, and the top of the locking rod 122 can extend out of the mounting hole 211. The latching member 112 can move in the opposite direction to the above-mentioned direction of movement (for example, the latching member 112 can move backward relative to the frame) to a position that at least blocks the mounting hole 211. The latching member 112 can cooperate with the locking rod 122 extending out of the mounting hole 211 to limit the movement stroke of the locking rod 122.

[0086] Since reciprocating motion can be achieved through a simple linkage mechanism or a gear and rack mechanism, there is no need to set up complex gearboxes or other devices, which can effectively reduce the structural complexity of the first locking assembly 110 and reduce the production cost of the first locking assembly 110.

[0087] Combination Figures 4 to 6 In some embodiments of this application, the first locking assembly 110 includes a rotating member 111, which cooperates with the latching member 112 to drive the latching member 112 to move.

[0088] In the above technical solution, by setting the rotating member 111, the reciprocating movement of the snap-fit ​​member 112 can be realized, and the structure of the first locking component 110 can be simplified, and the production cost of the first locking component 110 can be reduced.

[0089] For example, the rotating member 111 can be poweredly connected to an external driving device, which can drive the rotating member 111 to rotate. While the rotating member 111 is rotating, it can drive the latching member 112 to move. For example, the rotating member 111 can be a cam mechanism, which cooperates with the latching member 112. When the cam mechanism rotates clockwise, the latching member 112 can move in a direction to avoid the hanging hole 211 under the drive of the cam mechanism, so that the first locking component 110 can be switched to the unlocked state. When the cam mechanism rotates counterclockwise, the latching member 112 can move in a direction to at least block the hanging hole 211 under the drive of the cam mechanism, so that the first locking component 110 can be switched to the locked state.

[0090] It should be noted that the "external drive device" can be the motor of the battery swapping station.

[0091] It is understood that the above-described configuration of the rotating component 111 as a cam mechanism and the driving method of the cam mechanism to the snap-fit ​​component 112 are only examples of this application and should not be construed as limiting this application. The rotating component 111 can also be configured in other ways, which can be determined according to actual production requirements, and no specific limitation is made here.

[0092] Reference Figures 4 to 6 In some embodiments of this application, there are multiple snap-fit ​​members 112, and the rotating member 111 cooperates with multiple snap-fit ​​members 112 respectively. The rotating member 111 rotates to drive each snap-fit ​​member 112 to move, and each snap-fit ​​member 112 is used to block or avoid the corresponding hanging hole 211.

[0093] In the above technical solution, by setting multiple snap-fit ​​components 112 and having the rotating component 111 cooperate with multiple snap-fit ​​components 112 respectively, it is beneficial to further simplify the structure of the first locking component 110, reduce the production cost of the first locking component 110, and reduce the complexity of the action when the first locking component 110 is unlocked and locked, thereby improving the locking and unlocking efficiency of the first locking component 110 and thus improving the battery swapping efficiency.

[0094] For example, the battery device 220 is provided with multiple locking rods 122, and the frame is provided with multiple hanging holes 211. Each hanging hole 211 is used to pass through a corresponding locking rod 122. Multiple latching members 112 are provided, and each latching member 112 is provided with at least one hanging hole 211. When the rotating member 111 rotates, the rotating member 111 can simultaneously drive the multiple latching members 112 that cooperate with it, so that the multiple latching members 112 that cooperate with it can simultaneously avoid or block the corresponding hanging hole 211 without having to drive each latching member 112 individually. This helps to simplify the structure of the first locking component 110 and reduces the complexity of the first locking component 110's unlocking and locking actions, improving the locking and unlocking efficiency of the first locking component 110, thereby improving the battery swapping efficiency.

[0095] Please combine Figure 5 , Figure 6 , Figure 8 and Figure 9 In some embodiments of this application, the rotating member 111 includes a gear 1111 and a drive shaft 1112, with the gear 1111 disposed on the drive shaft 1112; the snap-fit ​​member 112 includes a rack portion 1121 and a blocking portion 1122, and the rotating member 111 meshes with the rack portions 1121 of the two snap-fit ​​members 112 respectively to drive the two snap-fit ​​members 112 to move towards each other or away from each other. In the locked state, at least one blocking portion 1122 is provided below the locking rod 122.

[0096] In the above technical solution, by constructing the rotating part 111 and the locking part 112 to cooperate in the manner of gear 1111 and rack, it is beneficial to improve the transmission accuracy of the rotating part 111 and the locking part 112, and also beneficial to improve the transmission efficiency of the rotating part 111 and the locking part 112. At the same time, it is beneficial to improve the compactness of the cooperation between the rotating part 111 and the locking part 112, and reduce the space required for arranging the first locking assembly 110. By providing a blocking part 1122 on the locking part 112, the locking part 112 can limit the locking rod 122.

[0097] For example, each gear 1111 may have a corresponding latching member 112 on both sides in the radial direction. A rack portion 1121 may be formed on the sidewalls of the two latching members 112 that are facing each other. Each gear 1111 meshes with the rack portion 1121 of the two latching members 112. At the same time, the gear 1111 is mounted on the drive shaft 1112. The drive shaft 1112 drives the gear 1111 to rotate. When the gear 1111 rotates, it can drive the two latching members 112 that mesh with it through the rack portion 1121 to move towards each other or away from each other, so that each latching member 112 can switch between a locked state and an unlocked state.

[0098] When the latching member 112 moves to the locked state, at least one blocking part 1122 is provided below the locking rod 122. The blocking part 1122 can limit the locking rod 122 below the locking rod 122, thereby limiting the battery device 220 and locking the battery device 220 to the frame.

[0099] In the locked state, a blocking part 1122 may be provided below the locking rod 122; in other examples, in the locked state, two blocking parts 1122 may be provided below the locking rod 122, and the two snap-fit ​​pieces 112 may be located on both sides of the locking rod 122 respectively; it is understood that in the locked state, the specific number of blocking parts 1122 below the locking rod 122 can be determined according to actual production requirements, and is not specifically limited here.

[0100] It is understood that the above-described configuration of the rotating part 111 and the snap-fit ​​part 112 using a gear 1111 and a rack structure is only one embodiment of this application and should not be construed as a limitation of this application. The rotating part 111 and the snap-fit ​​part 112 can also be configured to use a screw nut or other structures for cooperation. The specific cooperation method between the rotating part 111 and the snap-fit ​​part 112 can be determined according to actual production requirements and is not specifically limited here.

[0101] Please combine Figures 2 to 6 In some embodiments of this application, in the locked state, each locking lever 122 is provided with two blocking portions 1122 of the latching member 112 below it, and the two blocking portions 1122 are located on both sides of the locking lever 122 in the moving direction of the latching member 112.

[0102] In the above technical solution, in the locked state, by providing two blocking parts 1122 of the latching member 112 below each locking rod 122, and positioning the two blocking parts 1122 on both sides of the locking rod 122 in the moving direction of the latching member 112, it is beneficial to reduce the risk of the locking rod 122 shifting or shaking in the locked state, thereby improving the stability of the battery device 220 mounting.

[0103] For example, each gear 1111 has two locking members 112 with a blocking part 1122 on the same side of one end, and the blocking parts 1122 of the two locking members 112 are arranged opposite to each other in the moving direction of the locking members 112. When the locking members 112 move to the locked state under the drive of the rotating member 111, the blocking parts 1122 of the two locking members 112 are located on both sides of the locking rod 122 and below the locking rod 122 in the moving direction of the locking members 112, so as to simultaneously support and limit the locking rod 122 on both sides of the locking rod 122, improve the uniformity of the force on the locking rod 122 in the locked state, thereby helping to reduce the risk of the locking rod 122 shifting or shaking, and thus helping to improve the stability of the battery device 220 when it is mounted on the frame, and reduce the risk of the battery device 220 shaking or even falling off.

[0104] Please combine Figures 2 to 6 In some embodiments of this application, each latching member 112 includes two blocking portions 1122, which are respectively located at both ends of the latching member 112 in the moving direction. The blocking portions 1122 at the same end of the two latching members 112 corresponding to each gear 1111 are arranged opposite to each other in the moving direction of the latching member 112. In the locked state, two blocking portions 1122 of the latching member 112 are provided below each locking rod 122, and the two blocking portions 1122 are located on both sides of the locking rod 122 in the moving direction of the latching member 112.

[0105] In the above technical solution, each latching member 112 is designed to include two blocking parts 1122, and the two blocking parts 1122 are respectively located at both ends of the latching member 112 in the moving direction. The blocking parts 1122 at the same end of the two latching members 112 corresponding to each gear 1111 are arranged opposite to each other in the moving direction of the latching member 112, so that the two latching members 112 corresponding to each gear 1111 can lock and limit the two locking rods 122 respectively. This helps to simplify the structure of the locking mechanism 100, reduce the production cost of the locking mechanism 100, and facilitate the disassembly, assembly and maintenance of the locking mechanism 100.

[0106] Please combine Figure 8 and Figure 9 In some embodiments of this application, each blocking part 1122 is provided with a slot 1123, and in the locked state, a portion of the locking rod 122 is located in the slot 1123.

[0107] In the above technical solution, by providing a slot 1123 for each blocking part 1122, and in the locked state, a portion of the locking rod 122 is located in the slot 1123, so that the blocking part 1122 can clamp the locking rod 122, which helps to reduce the risk of the locking rod 122 shaking, thereby reducing the risk of the battery device 220 shaking when mounted on the vehicle frame and improving the mounting stability of the battery device 220.

[0108] For example, each gear 1111 has two locking members 112 with a blocking part 1122 on the same side. The blocking parts 1122 of the two locking members 112 are arranged opposite to each other in the moving direction of the locking members 112. When the locking members 112 are moved to the locked state under the drive of the rotating member 111, the blocking parts 1122 of the two locking members 112 are located on both sides of the locking rod 122 in the moving direction of the locking members 112. The slots 1123 of the two blocking parts 1122 are open in the direction facing each other. A part of the locking rod 122 extends into the slot 1123. The two blocking parts 1122 can clamp the locking rod 122 on both sides of the locking rod 122 to reduce the risk of the locking rod 122 shifting or shaking. This helps to reduce the risk of the battery device 220 shaking or even falling off and improves the stability of the battery device 220 when it is mounted on the vehicle frame.

[0109] Please combine Figure 8 and Figure 9 In some examples of this application, the inner wall surface of the slot 1123 is adapted to the outer contour of the portion of the locking rod 122 located within the slot 1123. For example, the locking rod 122 can be constructed as a cylindrical rod, and the inner wall surface of the slot 1123 provided for each blocking part 1122 is constructed as an arc-shaped wall surface to improve the effect of the blocking parts 1122 on both sides of the locking rod 122 clamping the locking rod 122 and improve the stability of the locking rod 122.

[0110] Please combine Figure 6 and Figure 7 In some embodiments of this application, the locking rod 122 and the blocking part 1122 are both provided with mating inclined surfaces 130 at the ends of their sidewalls facing each other.

[0111] In the above technical solution, by providing a mating inclined surface 130 at the ends of the locking rod 122 and the blocking part 1122 facing each other, the locking rod 122 is guided even when there is a positional deviation between the locking rod 122 and the blocking part 1122 in the vertical direction, thereby reducing the risk of damage to the blocking part 1122 during the engagement of the locking rod 122 due to the positional deviation between the locking rod 122 and the blocking part 1122.

[0112] For example, the top of the locking rod 123 may be provided with a locking protrusion 123. The locking protrusion 123 may be constructed as a square protrusion. The edge of the locking protrusion 123 facing the blocking part 1122 may be provided with a chamfer to form a mating slope 130. Correspondingly, the edge of the blocking part 1122 that can contact and engage with the locking protrusion 123 may be provided with a chamfer to form a mating slope 130. When it is necessary for the blocking part 1122 to support and limit the locking protrusion 123, the locking protrusion 123 may be provided with a chamfer. Furthermore, when the locking protrusion 123 and the blocking part 1122 interfere with each other during the process of the blocking part 1122 moving to the locked state due to the positional deviation in the vertical direction, the mating inclined surface 130 provided on the locking protrusion 123 and the blocking part 1122 can make contact and engage to guide the locking protrusion 123 upward, thereby reducing the risk of damage to the locking protrusion 123 and the blocking part 1122 due to mutual interference.

[0113] It is understood that the structural shape of the locking protrusion 123 and the forming method of the mating surface of the blocking part 1122 are merely examples for the purpose of illustration and should not be construed as a limitation of this application. The structural shape of the locking protrusion 123 and the forming method of the mating surface of the blocking part 1122 can be determined according to actual production requirements and are not specifically limited here.

[0114] Combination Figure 5 and Figure 6 as well as Figure 8 and Figure 9 In some embodiments of this application, the drive shaft 1112 is fitted with a ball bearing 113.

[0115] In the above technical solution, by mounting a ball bearing 113 around the drive shaft 1112, the ball bearing 113 can provide stable support for the drive shaft 1112, and help reduce the impact of frictional resistance on the drive shaft 1112, improving the smoothness of the drive shaft 1112's rotation. At the same time, since the ball bearing 113 has a certain elasticity and self-aligning ability, when there is a positional deviation in the drive shaft 1112, the ball bearing 113 can compensate for the error, so as to facilitate the insertion and engagement of the drive shaft 1112 and the transmission rod 121, and help improve the success rate of the insertion and engagement of the drive shaft 1112 and the transmission rod 121.

[0116] For example, the ball bearing 113 is sleeved on the radial outer side of the drive shaft 1112, and the ball bearing 113 can be interference-fitted with the drive shaft 1112 to improve the connection reliability between the drive shaft 1112 and the ball bearing 113, reduce the risk of relative sliding between the drive shaft 1112 and the ball bearing 113, thereby improving the effectiveness of power transmission.

[0117] When the drive shaft 1112 tilts or shifts due to external force or assembly deviation, the ball bearing 113 can adjust the position of the drive shaft 1112 by the rolling of the internal balls to compensate for the error. This prevents the drive shaft 1112 from failing to engage with the transmission rod 121 due to tilting or shifting, and helps to improve the success rate of engagement between the drive shaft 1112 and the transmission rod 121.

[0118] In some examples, the outer contour of the drive shaft 1112 can be a polygon, and the shape of the wall of the ball bearing 113 opposite to the drive shaft 1112 is adapted to the outer contour of the drive shaft 1112 to improve the reliability of the fit between the drive shaft 1112 and the ball bearing 113.

[0119] Combination Figure 5 and Figure 6 as well as Figure 8 and Figure 9 In some embodiments of this application, the frame is provided with mounting holes 2121, and the ball bearing 113 is sleeved on the drive shaft 1112 and disposed in the mounting holes 2121.

[0120] In the above technical solution, by setting mounting holes 2121 on the frame, the ball bearing 113 is positioned and installed, which helps to improve the assembly stability of the ball bearing 113, reduce the risk of the ball bearing 113 moving, and thus improve the cooperation effect between the ball bearing 113 and the drive shaft 1112.

[0121] For example, the frame may be provided with mounting holes 2121, and the diameter of the mounting holes 2121 is smaller than the outer diameter of the ball bearing 113, so that the ball bearing 113 can be interference-fitted with the frame, thereby improving the support effect of the frame on the ball bearing 113 and improving the assembly stability of the ball bearing 113. This, in turn, helps to improve the reliability of the fit between the ball bearing 113 and the drive shaft 1112, and further helps to improve the effectiveness of power transmission of the drive shaft 1112.

[0122] Combination Figures 4 to 6 as well as Figure 8 and Figure 9 In some embodiments of this application, the first locking assembly 110 further includes a pressure plate 114, which is placed on the side of the ball bearing 113 away from the frame and contacts the ball bearing 113 to limit the displacement of the ball bearing 113.

[0123] In the above technical solution, by setting a pressure plate 114 that contacts and cooperates with the ball bearing 113 on the side of the ball bearing 113 away from the frame, the displacement of the ball bearing 113 is restricted, the displacement of the ball bearing 113 caused by the force acting on the side away from the frame is reduced, the assembly reliability of the ball bearing 113 is improved, and the wear between the ball bearing 113 and the drive shaft 1112 is reduced.

[0124] For example, the pressure plate 114 is disposed on the frame and located on the side of the ball bearing 113 away from the frame. The pressure plate 114 can contact and engage with the ball bearing 113 on the side away from the frame to limit the ball bearing 113 on the side away from the frame. When the ball bearing 113 is subjected to a force in the direction away from the frame, the ball bearing 113 can maintain positional stability under the limiting action of the pressure plate 114, preventing relative sliding between the ball bearing 113 and the drive shaft 1112, thereby helping to reduce wear between the ball bearing 113 and the drive shaft 1112.

[0125] Combination Figure 5 and Figure 6 as well as Figure 8 and Figure 9 In some examples, the frame is provided with mounting holes 2121, and the ball bearing 113 is sleeved on the drive shaft 1112 and disposed in the mounting holes 2121. By providing a pressure plate 114 that contacts and engages with the ball bearing 113 on the side of the ball bearing 113 away from the frame, the ball bearing 113 is limited on the side away from the frame, reducing the risk of the ball bearing 113 coming out of the mounting holes 2121 when subjected to a force in the direction away from the drive rod 121, thereby improving the assembly stability of the ball bearing 113 and the frame.

[0126] Combination Figure 5 and Figure 6 as well as Figure 8 and Figure 9 In some embodiments of this application, two pressure plates 114 are provided on the side of the ball bearing 113 away from the frame. The two pressure plates 114 are in contact with the ball bearing 113 and are located on both sides of the drive shaft 1112.

[0127] In the above technical solution, by setting two pressure plates 114 on the side of the ball bearing 113 away from the frame, and making the two pressure plates 114 contact the ball bearing 113 respectively, it is beneficial to improve the uniformity of force on the ball bearing 113 and reduce the risk of the ball bearing 113 becoming misaligned, thereby further improving the assembly stability of the ball bearing 113. By arranging the two pressure plates 114 on both sides of the drive shaft 1112 to avoid the drive shaft 1112, it is beneficial to reduce the risk of the pressure plates 114 interfering with the rotation of the drive shaft 1112, thereby improving the power transmission effect of the drive shaft 1112.

[0128] For example, the ball bearing 113 is provided with two pressure plates 114. Both pressure plates 114 are located on the side of the ball bearing 113 away from the frame and are in contact with the ball bearing 113 to limit the ball bearing 113 and improve the limiting effect of the ball bearing 113. The two pressure plates 114 are respectively located on both sides of the drive shaft 1112 in the radial direction and are spaced apart from the drive shaft 1112 to improve the uniformity of force on the ball bearing 113 while avoiding interference of the pressure plates 114 with the rotation of the drive shaft 1112. This is beneficial to improving the smoothness of the rotation of the drive shaft 1112, thereby improving the power transmission effect of the drive shaft 1112.

[0129] Combination Figures 4 to 6 as well as Figure 8 and Figure 9 In some embodiments of this application, the pressure plate 114 is fixedly mounted on the frame and located on the side of the ball bearing 113 away from the frame.

[0130] In the above technical solution, fixing the pressure plate 114 to the frame helps to improve the assembly stability of the pressure plate 114, thereby improving the effectiveness of the pressure plate 114 in limiting the ball bearing 113.

[0131] For example, bolt holes may be provided on the frame, the bolt holes being located circumferentially outside the mounting hole 2121, and the pressure plate 114 may be fixedly mounted on the frame by bolts to facilitate the installation and removal of the pressure plate 114.

[0132] Combination Figure 8 and Figure 9 In some specific examples, the ball bearing 113 is provided with two pressure plates 114. Each pressure plate 114 is fixed to the frame by bolts at its end in the extension direction. This improves the uniformity of the force on the ball bearing 113 and further improves the assembly stability of the pressure plate 114, thereby improving the effectiveness of the pressure plate 114 in limiting the ball bearing 113.

[0133] It is understood that the above-mentioned method of fixing the pressure plate 114 to the frame with bolts is only an example of this application and should not be construed as a limitation of this application. The pressure plate 114 can also be fixedly installed on the frame in other ways, such as by welding or snap-fitting. The method of fixing the pressure plate 114 to the frame can be determined according to actual production requirements and is not specifically limited here.

[0134] Combination Figures 8 to 11 In some embodiments of this application, the first locking component 110 further includes a guide 115 for guiding the movement of the card connector 112.

[0135] In the above technical solution, by setting the guide 115, the locking member 112 can move along a specific trajectory, which helps to improve the accuracy of the movement of the locking member 112, thereby improving the efficiency of locking and unlocking the locking member 112 on the locking rod 122.

[0136] For example, the snap-fit ​​member 112 may be provided with a guide groove, and the guide member 115 may be embedded in the guide groove. The snap-fit ​​member 112 slides with the guide member 115 through the guide groove, so that the snap-fit ​​member 112 can move along the extension direction of the guide member 115, thereby realizing the function of the guide member 115 guiding the movement stroke of the snap-fit ​​member 112.

[0137] Combination Figures 8 to 11 In some embodiments of this application, the cross section of the guide 115 is "I" shaped in the moving direction of the locking rod 122, so as to improve the reliability of the engagement between the guide 115 and the snap-fit ​​112 and reduce the risk of the snap-fit ​​112 and the guide 115 disengaging from each other.

[0138] For example, in the moving direction of the locking rod 122, which can also be understood as the up-down or vertical direction, the cross-sectional area of ​​the middle position of the guide member 115 is smaller than the cross-sectional area of ​​the two ends of the guide member 115. The shape of the guide groove on the latching member 112 is adapted to the shape of the guide member 115. In the moving direction of the locking rod 122, the end of the guide member 115 can be limited to cooperate with the latching member 112 to reduce the risk of the latching member 112 and the guide member 115 disengaging from each other, improve the reliability of the cooperation between the latching member 112 and the guide member 115, and thus improve the effectiveness of the guide member 115 in guiding the latching member 112.

[0139] Combination Figures 8 to 11 In some embodiments of this application, the guide 115 is fixedly connected to the vehicle frame to improve the assembly reliability of the guide 115 and reduce the risk of the guide 115 moving, thereby improving the stability of the movement of the snap-fit ​​112.

[0140] In some examples, the guide 115 can be fixedly connected to the frame via threaded fasteners (such as screws or bolts), and multiple threaded fasteners can be provided in the extending direction of the guide 115 to further improve the assembly reliability of the guide 115 and facilitate the assembly and disassembly of the guide 115. In other examples, the guide 115 can be fixedly connected to the frame by welding to improve the assembly reliability of the guide 115. It is understood that the specific fixed connection method between the guide 115 and the frame can be determined according to actual production requirements, and no specific limitation is made here.

[0141] In some embodiments of this application, the first locking assembly 110 further includes a bracket base, the bracket base having a through hole for the locking rod 122 to pass through, the first locking assembly 110 being disposed on the bracket base, and the drive shaft 1112 of the rotating member 111 passing through the bracket base and cooperating with the transmission rod 121.

[0142] In the above technical solution, by setting a support base, the first locking component 110 and the support base can be modularly assembled, which helps to improve the production and assembly efficiency of the locking mechanism 100.

[0143] For example, the bracket base can serve as the mounting carrier for the first locking assembly 110, providing support for the first locking assembly 110. Structures such as gear 1111, guide 115, snap-fit ​​112, and pressure plate 114 can be disposed on one side surface of the bracket base. Ball bearing 113 can be embedded in the bracket base. Drive shaft 1112 is connected to gear 1111 and passes through ball bearing 113. The end of drive shaft 1112 away from gear 1111 extends out from the side of bracket base away from gear 1111 and other components, so as to cooperate with components disposed on the side of bracket base away from gear 1111 and other components (such as transmission rod 121). Locking rod 122 can extend out from the side of bracket base away from gear 1111 and other components through through hole and selectively lock into snap-fit ​​112.

[0144] In short, components such as gear 1111, guide 115, snap-fit ​​112, pressure plate 114, and ball bearing 113 can be pre-installed on the bracket base to form an installation module with the bracket base as the carrier. The installation module can then be further installed on the frame and positioned and installed with components such as locking rod 122. This eliminates the need to position each component of the first locking assembly 110 separately with the frame, which helps to improve the production and assembly efficiency of the locking mechanism 100.

[0145] In some other embodiments of this application, the first locking component 110 can be directly mounted on the vehicle frame to simplify the structure of the locking mechanism 100 and reduce the production cost of the locking mechanism 100.

[0146] It should be noted that in the embodiment where the locking mechanism 100 includes a bracket base, the aforementioned mounting hole 2121 is formed on the bracket base so that the ball bearing 113 can be embedded in the bracket base. The frame is provided with a hole structure opposite to the mounting hole 2121 so that the drive shaft 1112 can pass through the bracket base. In addition, the through hole is directly opposite to the hanging hole 211 so that the locking rod 122 can pass through the bracket base. In the embodiment where the first locking assembly 110 is directly mounted on the frame, the aforementioned mounting hole 2121 is formed on the frame so that the ball bearing 113 can be mounted on the frame.

[0147] Combination Figures 2 to 6 as well as Figure 10 and Figure 11 According to some embodiments of this application, the locking mechanism 100 for chassis battery swapping includes: a first locking component 110 and a second locking component. The first locking component 110 is the first locking component 110 described above, and the first locking component 110 is adapted to be disposed on the vehicle frame. The second locking component is located in the battery device 220. The second locking component includes a locking rod 122. In the unlocked state, the latching member 112 avoids the hanging hole 211 to avoid the movement stroke of the locking rod 122. In the locked state, the latching member 112 at least blocks the hanging hole 211 and cooperates with the locking rod 122 extending out of the hanging hole 211 to limit the movement stroke of the locking rod 122.

[0148] In the above technical solution, by making the latching member 112 movable relative to the vehicle frame, the latching member 112 can selectively avoid or at least block the mounting hole 211. When the latching member 112 at least blocks the mounting hole 211, the latching member 112 can cooperate with the locking rod 122 extending out of the mounting hole 211 to limit the movement of the locking rod 122. In this process, there is no need to drive the locking rod, which helps to reduce the complexity of the unlocking and locking actions when mounting or dismounting the battery device 220, thereby improving the battery swapping efficiency. In addition, since the latching member 112 can at least block the mounting hole 211, it helps to reduce the risk of dust or rainwater and other debris falling into the battery device 220 through the mounting hole 211.

[0149] For example, please combine Figures 2 to 6The locking lever 122, mounted on the battery assembly 220, can pass through the mounting hole 211 and reciprocate relative to the mounting hole 211. Before battery swapping, the battery assembly 220 is mounted on the vehicle frame. At this time, the locking lever 122 extends from the mounting hole 211, and the latching member 112 moves to a position that at least blocks the mounting hole 211. The latching member 112 can engage with at least a portion of the locking lever 122 extending from the mounting hole 211 to limit the travel of the locking lever 122. For example, before battery swapping, the locking lever 122... The top of the latch 112 extends out of the hanging hole 211. At least a portion of the latch 112 can be located at a position opposite to the hanging hole 211 in the vertical direction and can be engaged with the top of the locking rod 122 in the vertical direction to limit the movement of the locking rod 122 and improve the stability of the battery device 220 when it is mounted on the vehicle 1000. Since the latch 112 blocks at least a portion of the hanging hole 211, the risk of dust or rainwater and other debris falling into the battery device 220 through the hanging hole 211 can be effectively reduced.

[0150] Combination Figure 10 and Figure 11 When a battery swap is required, the latching member 112 moves to a position vertically offset from the mounting hole 211 to avoid it. Under the weight of the battery device 220, the locking rod 122 tends to move downwards vertically. Since the latching member 112 avoids the mounting hole 211, it does not interfere with the movement of the locking rod 122. Therefore, the locking rod 122 can be driven downwards and disengaged from the mounting hole 211 under the weight of the battery device 220, allowing the battery device 220 to move relative to the frame, facilitating its removal.

[0151] Combination Figures 2 to 6 After the original battery device 220 mounted on the frame is removed, the new battery device 220 can be positioned with the frame. At this time, the locking rod 122 can pass through the mounting hole 211 from bottom to top, and the top of the locking rod 122 can extend out of the mounting hole 211. The latching member 112 moves to a position that at least blocks the mounting hole 211. The latching member 112 can cooperate with the locking rod 122 extending out of the mounting hole 211 to limit the movement of the locking rod 122.

[0152] Therefore, during the battery swapping process, the locking lever 122 on the battery device 220 does not need to be driven, which helps to reduce the complexity of the unlocking and locking actions of the locking mechanism 100 when mounting or dismounting the battery device 220, thereby improving the battery swapping efficiency.

[0153] Combination Figures 2 to 6 as well as Figure 10 and Figure 11In some embodiments of this application, there are multiple locking rods 122, and each locking rod 122 has a locking protrusion 123 on its top. In the locked state, each locking protrusion 123 has at least one latching member 112 below it to limit its movement stroke. In the unlocked state, the latching member 112 avoids the movement stroke of the locking rod 122.

[0154] In the above technical solution, by setting multiple locking rods 122, it is beneficial to improve the stability of the battery device 220 mounting and reduce the risk of the battery device 220 falling off the vehicle frame. By setting a locking protrusion 123 on the top of each locking rod 122, it is convenient for the latching member 112 to cooperate with the locking rod 122, thereby making it easier for the latching member 112 to limit the movement stroke of the locking rod 122.

[0155] For example, when the battery device 220 is mounted on the vehicle frame, at least one latching member 122 is provided below each locking protrusion 123. The latching member 122 can limit the locking protrusion 123 below the locking protrusion 123 to restrict the vertical movement of the locking protrusion 123. Since the locking rod 122 with the locking protrusion 123 is provided on the battery device 220, the latching member 112 can limit the vertical movement of the battery device 220 through the locking protrusion 123 to realize the mounting of the battery device 220 on the vehicle frame.

[0156] Combination Figures 4 to 6 In some embodiments of this application, the first locking assembly 110 includes a rotating member 111, which cooperates with a snap-fit ​​member 112 to drive the snap-fit ​​member 112 to move; the second locking assembly includes a transmission rod 121, which cooperates with the rotating member 111 to drive the rotating member 111 to rotate.

[0157] In the above technical solution, by setting up a transmission rod 121 and a rotating component 111 that cooperate with each other, power can be transmitted to the locking component 112, thereby facilitating the movement of the locking component 112.

[0158] For example, the transmission rod 121 can be selectively connected to an external drive device. When the external drive device is connected to the transmission rod 121, the external drive device can drive the transmission rod 121 to rotate. The transmission rod 121 cooperates with the rotating member 111 to drive the rotating member 111 to rotate relative to the frame. The rotating member 111 cooperates with multiple locking members 112 to drive the multiple locking members 112 to move. The multiple locking members 112 can cooperate with the locking protrusions 123 of multiple locking rods 122 to limit the movement of the locking rods 122.

[0159] Please combine Figures 2 to 6Before battery swapping, the battery device 220 is mounted on the vehicle frame. At this time, multiple latching members 112 are in a locked state. That is, at least one latching member 112 is provided below each locking protrusion 123. The latching member 112 can limit the locking protrusion 123 below the locking protrusion 123 to restrict the vertical movement of the locking protrusion 123. Since the locking rod 122 with the locking protrusion 123 is provided on the battery device 220, the latching member 112 can limit the vertical movement of the battery device 220 through the locking protrusion 123 to lock the battery device 220 on the vehicle frame.

[0160] Combination Figure 10 and Figure 11 When a battery swap is required, the external drive unit is powered to drive the transmission rod 121 to rotate. The transmission rod 121 drives multiple locking parts 112 to move to the unlocked state through the rotating part 111. At this time, each locking part 112 and its corresponding locking protrusion 123 are offset in the vertical direction so that the locking part 112 can avoid the locking protrusion 123 on the moving trajectory of the locking rod 122. That is, at this time, the locking part 112 releases the locking rod 122, so that the locking rod 122 can move relative to the frame, thereby allowing the battery device 220 to move relative to the frame, which facilitates the removal of the battery device 220.

[0161] Combination Figures 2 to 6 After the original battery device 220 mounted on the frame is removed, the new battery device 220 can be positioned with the frame. The external drive device drives the transmission rod 121 to rotate. The transmission rod 121 drives multiple locking parts 112 to move to the locked state through the rotating part 111. At this time, at least one locking part 112 is provided below the locking protrusion 123 of each locking rod 122 of the battery device 220. The locking part 112 can limit the locking protrusion 123 below the locking protrusion 123 to limit the vertical movement of the locking protrusion 123. The locking part 112 can limit the vertical movement of the battery device 220 through the locking protrusion 123 to lock the battery device 220 on the frame, thus achieving the purpose of mounting the new battery device 220 on the frame.

[0162] Combination Figure 5 and Figure 6 as well as Figure 8 and Figure 9 In some embodiments of this application, the rotating member 111 includes a drive shaft 1112 that cooperates with the transmission rod 121, and the drive shaft 1112 and the transmission rod 121 are inserted into each other.

[0163] In the above technical solution, the drive shaft 1112 and the transmission rod 121 are inserted and fitted together to facilitate the positioning and installation of the drive shaft 1112 and the transmission rod 121, thereby improving the production and assembly convenience of the locking mechanism 100 and thus improving the production efficiency of the locking mechanism 100.

[0164] In some examples, the end of the transmission rod 121 facing the drive shaft 1112 may have a groove that opens towards the drive shaft 1112. The drive shaft 1112 can be inserted into the groove to achieve a plug-in fit between the drive shaft 1112 and the transmission rod 121. Furthermore, the drive shaft 1112 and the transmission rod 121 may have an interference fit to improve the power transmission effect between the drive shaft 1112 and the transmission rod 121. In some other examples, the transmission rod 121 and the drive shaft 1112 can be a non-standard plug-in fit; in still other examples, the transmission rod 121 and the drive shaft 1112 can be a spline plug-in fit; it is understood that the specific plug-in fit between the drive shaft 1112 and the transmission rod 121 can be determined according to actual production requirements, and no specific limitation is made here.

[0165] Combination Figure 8 and Figure 9 as well as Figure 12 and Figure 13 In some embodiments of this application, the transmission rod 121 is provided with a top-open spline groove 1211, and at least a portion of the drive shaft 1112 is formed as a spline, with the spline located within the spline groove 1211.

[0166] In the above technical solution, by providing a top-open spline groove 1211 on the transmission rod 121 and forming at least a portion of the drive shaft 1112 as a spline, the transmission rod 121 and the drive shaft 1112 can form a spline insertion fit, which helps to reduce the risk of slippage between the drive shaft 1112 and the transmission rod 121, and improves the effect and efficiency of power transmission between the transmission rod 121 and the drive shaft 1112. At the same time, it facilitates the disassembly and maintenance of the transmission rod 121 and the drive shaft 1112.

[0167] For example, a spline groove 1211 may be provided at one end of the transmission rod 121 near the drive shaft 1112. The spline groove 1211 is open at one end facing the transmission rod 121. At least a portion of the drive shaft 1112 may be formed as a spline and inserted into the spline groove 1211 through the open end of the spline groove 1211, so that the transmission rod 121 and the drive shaft 1112 can form a spline insertion fit. Since the contact area of ​​the spline is large, the spline insertion fit between the transmission rod 121 and the drive shaft 1112 can withstand a larger torque than other methods, and its torque transmission is more stable, which helps to avoid slippage during transmission and improves the reliability of transmission between the transmission rod 121 and the drive shaft 1112.

[0168] In some examples, the end of the drive shaft 1112 near the transmission rod 121 is formed as a spline; in other examples, the entire drive shaft 1112 is formed as a spline. It is understood that the specific part of the drive shaft 1112 that is formed as a spline can be determined according to actual production requirements, and no specific limitation is made here.

[0169] Combination Figure 8 and Figure 9 as well as Figure 12 and Figure 13 In some embodiments of this application, the top of the spline groove 1211 is provided with a guide surface 1212 that extends obliquely toward the interior of the spline groove 1211.

[0170] In the above technical solution, by providing a guide surface 1212 that extends obliquely toward the inside of the spline groove 1211 at the top of the spline groove 1211, the spline is guided and positioned during the process of inserting the spline into the spline groove 1211, which is beneficial to improve the convenience of the insertion and engagement of the drive shaft 1112 and the transmission rod 121.

[0171] For example, a guide surface 1212 is provided at one end of the spline groove 1211 near the drive shaft 1112. In the direction in which the drive shaft 1112 extends toward the transmission rod 121, the cross-sectional area of ​​the portion of the spline groove 1211 with the guide surface 1212 is gradually reduced, so as to guide the spline into the spline groove 1211 during the process of the spline being inserted into the spline groove 1211, thereby improving the convenience of the spline and the spline groove 1211 being inserted and mated, which in turn helps to improve the convenience of the drive shaft 1112 and the transmission rod 121 being inserted and mated.

[0172] Combination Figure 5 and Figure 6 as well as Figures 12 to 14In some embodiments of this application, the second locking assembly further includes a check mechanism 124, which cooperates with the transmission rod 121. The check mechanism 124 has a check state and a rotation state. In the check state, the rotational freedom of the transmission rod 121 is restricted, and in the rotational state, the transmission rod 121 can be driven to rotate.

[0173] In the above technical solution, by setting a check mechanism 124, the check mechanism 124 can restrict the rotational freedom of the transmission rod 121 in the check state, thereby restricting the position of the latching member 112 and improving the stability of the latching member 112 in the locked state. This helps to reduce the risk of the locking protrusion 123 disengaging from the latching member 112, and further helps to reduce the risk of the battery device 220 falling off. When the check mechanism 124 is in the rotating state, the transmission rod 121 can be driven to rotate to adjust the position of the latching member 112, thereby facilitating the release of the latching member 112 from the limiting engagement with the locking protrusion 123.

[0174] For example, when the battery device 220 is mounted on the vehicle frame, the check mechanism 124 is in a check state to restrict the rotational freedom of the transmission rod 121. Since the transmission rod 121 cooperates with the drive shaft 1112, and the drive shaft 1112 is provided with a gear 1111, which cooperates with the locking member 112, when the rotational freedom of the transmission rod 121 is restricted, the rotational freedom of the drive shaft 1112 and the gear 1111 are also restricted. At the same time, the locking member 112 cannot move under the action of the gear 1111, so that the locking member 112 can be kept in the position that cooperates with the locking boss limit, thereby improving the positional stability of the locking boss, which in turn improves the stability of the battery device 220 mounting and reduces the risk of the battery device 220 falling off.

[0175] When a battery swap is required, the check mechanism 124 switches to the rotation state, and the transmission rod 121 can be driven to rotate. The transmission rod 121 can drive the locking member 112 to move through the drive shaft 1112 and the gear 1111. The locking member 112 can move to a position that avoids the locking rod 122, so as to release the locking member 112 from the limiting engagement with the locking boss. The battery device 220 can be removed from the frame.

[0176] Combination Figure 5 and Figure 6 as well as Figures 12 to 14In some embodiments of this application, the check mechanism 124 includes: a fixed base 1241, a mating member 1242, and a check member 1243. The fixed base 1241 is adapted to be fixed to the battery device 220. The mating member 1242 cooperates with the transmission rod 121 to drive the transmission rod 121 to rotate synchronously. The check member 1243 cooperates with the mating member 1242 and is movably engaged with the fixed base 1241. In the check state, the check member 1243 cooperates with the fixed base 1241 to restrict the rotation of the mating member 1242. In the rotation state, the check member 1243 disengages from the fixed base 1241 to drive the mating member 1242 to rotate synchronously.

[0177] In the above technical solution, by setting a check member 1243 and a mating member 1242, the check member 1243 and the mating member 1242 are mated together, and the check member 1243 is selectively mated with the fixed seat 1241, so as to switch the working state of the check mechanism 124 by switching the mating state of the check member 1243 and the fixed seat 1241, thereby facilitating the adjustment of the limiting effect of the check mechanism 124 on the transmission rod 121.

[0178] For example, the fixed base 1241 is fixed to the battery device 220, the check member 1243 is disposed in the fixed base 1241, the mating member 1242 is disposed in the fixed base 1241, and the two axial ends of the mating member 1242 respectively protrude from the fixed base 1241. The end of the mating member 1242 facing the transmission rod 121 can cooperate with the transmission rod 121, and the end of the mating member 1242 away from the transmission rod 121 is used for transmission cooperation with an external drive device. The check member 1243 cooperates with the mating member 1242, and at the same time, the check member 1243 is movably cooperated with the fixed base 1241.

[0179] When the check mechanism 124 is in the check state, the check member 1243 cooperates with the fixed seat 1241, and the fixed seat 1241 can limit the check member 1243 so that the fixed seat 1241 can restrict the rotation of the mating member 1242 through the check member 1243; when the check mechanism 124 switches to the rotation state, the check member 1243 moves to the position where it is disengaged from the fixed seat 1241. At this time, the fixed seat 1241 releases the limit on the check member 1243, thereby releasing the effect of restricting the rotation of the mating member 1242. The mating member 1242 can transmit power to the locking member 112 through the transmission rod 121, the drive shaft 1112 and the gear 1111 to drive the locking member 112 to move. Combination Figure 5 and Figure 6 as well as Figures 12 to 14 In some embodiments of this application, in the check state, the check member 1243 and the fixed seat 1241 are engaged, and the check member 1243 can move relative to the mating member 1242 to switch to the rotation state.

[0180] In the above technical solution, since the fixing seat 1241 is fixed to the battery device 220, in the check state, by engaging the check member 1243 with the fixing seat 1241, the rotational freedom of the check member 1243 is restricted, thereby achieving the purpose of restricting the rotational freedom of the mating member 1242. By making the check member 1243 movable relative to the mating member 1242, it is convenient to release the engagement state between the check member 1243 and the fixing seat 1241, thereby facilitating the release of the restriction on the rotational freedom of the check member 1243, and thus facilitating the restoration of the rotational freedom of the mating member 1242.

[0181] For example, the fixed base 1241 may be provided with meshing teeth for engaging with the check member 1243. In the check state, the check member 1243 engages with the meshing teeth so that the fixed base 1241 can restrict the rotation of the check member 1243. The check member 1243 is movably sleeved on the mating member 1242, and the check member 1243 and the mating member 1242 are in a circumferential upper limit engagement. That is, the check member 1243 can move relative to the mating member 1242, but the check member 1243 cannot rotate relative to the mating member 1242. Therefore, the fixed base 1241 can restrict the rotation of the mating member 1242 through the check member 1243. The mating member 1242 limits the locking member 112 through the transmission rod 121, the drive shaft 1112 and the gear 1111 so that the position of the locking member 112 remains stable.

[0182] When a battery swap is required, the external drive unit can extend into the fixed base 1241 and drive the check member 1243 to move relative to the mating member 1242. The check member 1243 is disengaged from the fixed base 1241. The external drive unit cooperates with the mating member 1242 to drive the mating member 1242 to rotate. The mating member 1242 drives the locking member 112 to move through the transmission rod 121, drive shaft 1112 and gear 1111, thereby adjusting the position of the locking member 112 to release the locking member 112 from the limiting engagement with the locking boss, which facilitates the disassembly of the battery device 220.

[0183] Combination Figure 5 and Figure 6 as well as Figures 12 to 14 In some embodiments of this application, the check mechanism 124 further includes a reset member 1245. The reset member 1245 is elastically supported between the fixed base 1241 and the check member 1243. During the movement of the check member 1243 relative to the mating member 1242, the reset member 1245 undergoes elastic deformation. When the external driving device releases the driving force on the check member 1243, the check member 1243 can be reset under the drive of the reset member 1245, so that the check mechanism 124 can switch from the self-rotation state to the check state.

[0184] Combination Figures 12 to 14In some embodiments of this application, the mating member 1242 and the transmission rod 121 are inserted into each other; the locking mechanism 100 also includes an anti-loosening member, which is inserted into the mating member 1242 and the transmission rod 121 respectively.

[0185] In the above technical solution, by inserting the mating part 1242 into the transmission rod 121, the positioning and assembly of the mating part 1242 and the transmission rod 121 can be facilitated. By setting the anti-loosening part, the reliability of the mating part 1242 and the transmission rod 121 can be improved, and the risk of the power transmission effect being affected due to the loosening of the mating part 1242 and the transmission rod 121 can be reduced.

[0186] For example, a slot may be provided at the end of the transmission rod 121 facing the mating member 1242, and the mating member 1242 may be inserted into the slot to achieve the insertion and engagement of the mating member 1242 and the transmission rod 121. At the insertion and engagement position of the mating member 1242 and the transmission rod 121, an anti-loosening member is sequentially inserted into the mating member 1242 and the transmission rod 121 along the radial direction of the transmission rod 121. The anti-loosening member can fix the mating member 1242 and the transmission rod 121 in the direction of the insertion and engagement, thereby reducing the risk of the mating member 1242 and the transmission rod 121 being affected by loosening of the engagement, and is conducive to improving the engagement reliability of the mating member 1242 and the transmission rod 121, and reducing the risk of the mating member 1242 and the transmission rod 121 disengaging.

[0187] In some examples, the mating part 1242 and the transmission rod 121 can be splined, which is beneficial to improving the power transmission effect between the mating part 1242 and the transmission rod 121.

[0188] Combination Figures 2 to 6 According to an embodiment of this application, the chassis 200 includes: a frame, a battery device 220, and a locking mechanism 100. The frame is provided with a mounting hole 211. The battery device 220 is replaceably mounted on the frame. The locking mechanism 100 is the locking mechanism 100 described above. A first locking component 110 is mounted on the frame, and a second locking component is mounted on the battery device 220. A locking rod 122 can pass through the mounting hole 211 so that a locking protrusion 123 is located above the mounting hole 211. A snap-fit ​​member 112 switches to a locked state and is located below the locking protrusion 123 to position the battery device 220.

[0189] In the above technical solution, since the chassis 200 includes the locking mechanism 100, the battery replacement device 220 can be quickly replaced. Furthermore, since the locking mechanism 100 has a simple structure, it is beneficial to save the space required to arrange the locking mechanism 100, thereby increasing the space on the chassis 200 for arranging other components. At the same time, it is beneficial to simplify the structure of the chassis 200, reduce the production cost and weight of the chassis 200, and improve the production and assembly efficiency of the chassis 200.

[0190] For example, the locking lever 122 is connected to the battery device 220. The locking lever 122 can pass through the hanging hole 211 and make the locking protrusion 123 located above the hanging hole 211. The latching member 112 is located between the locking protrusion 123 and the hanging hole 211. In the locked state, the latching member 112 can move to the bottom of the locking protrusion 123 to restrict the movement of the locking protrusion 123. It can also be understood that the latching member 112 can lock the locking protrusion 123 above the hanging hole 211. Since the locking lever 122 is connected to the battery device 220, the latching member 112 can lock the battery device 220 on the frame, thereby realizing the mounting of the battery device 220 on the frame.

[0191] Furthermore, when the latching member 112 locks the locking protrusion 123 above the hanging hole 211, the latching member 112 and the locking protrusion 123 can block the hanging hole 211, thereby reducing the risk of dust and other debris entering the battery device 220 through the hanging hole 211 and the setting position of the locking rod 122. This helps to reduce the risk of increased rotational torque of components such as the transmission rod 121 due to the accumulation of dust and other debris in the battery device 220, and thus helps to improve the service life of the locking mechanism 100.

[0192] Combination Figures 2 to 6 In some examples of this application, the frame includes a battery bracket 212 for carrying a battery device 220, a mounting hole 211 is formed on the battery bracket 212, a first locking component 110 is disposed on the battery bracket 212, and a locking protrusion 123 can pass through the mounting hole 211 and engage with the first locking component 110 disposed on the battery bracket 212 to mount the battery device 220 on the battery bracket 212.

[0193] Combination Figures 2 to 6 In some embodiments of this application, the battery device 220 includes a battery housing 221, and the locking rod 122 includes a fixed rod 1221 and a lock head 1222 that are fixedly connected. The fixed rod 1221 is fixed to the housing, and the lock head 1222 extends out of the battery housing 221 and is provided with a locking protrusion 123.

[0194] In the above technical solution, by setting a fixing rod 1221, the lock head 1222 is fixed on the battery box 221, and the locking protrusion 123 is suspended above the battery box 221, so that the locking protrusion 123 can pass through the hanging hole 211 and cooperate with the snap-fit ​​member 112.

[0195] For example, the battery box 221 is provided with a limiting hole for installing the locking rod 122. During the installation of the locking rod 122, the lock head 1222 can be inserted into the limiting hole from the top of the battery box 221 first, and then the fixing rod 1221 can be inserted into the limiting hole from the bottom of the battery box 221 and connected to the lock head 1222. After the fixing rod 1221 and the lock head 1222 are assembled, the fixing rod 1221 can be further fixed to the battery box 221. The lock head 1222 can be fixedly connected to the battery box 221 through the fixing rod 1221 to improve the assembly reliability of the lock head 1222.

[0196] In some examples, the fixing rod 1221 and the lock head 1222 can be threaded together to facilitate the disassembly and maintenance of the fixing rod 1221 and the lock head 1222.

[0197] In some examples, the fixing rod 1221 can be fixedly connected to the battery box 221 by a threaded connector (such as a bolt) to facilitate the assembly and disassembly of the fixing rod 1221 from the battery box 221.

[0198] Combination Figures 2 to 6 In some embodiments of this application, the battery device 220 is provided with a receiving groove 222, and the locking rod 122 is provided with a stop protrusion 125, which abuts against the bottom wall of the receiving groove 222.

[0199] In the above technical solution, by providing a receiving groove 222 on the battery device 220 and by providing a stop protrusion 125 on the locking rod 122, the locking rod 122 and the battery device 220 are positioned, and the locking protrusion 123 is suspended above the battery box 221, so that the locking protrusion 123 can pass through the hanging hole 211 and cooperate with the snap-fit ​​member 112.

[0200] For example, the battery device 220 includes a battery housing 221. The portion of the battery housing 221 near the vehicle frame is provided with a receiving groove 222. The locking rod 122 includes a fixing rod 1221 and a lock head 1222. A stop protrusion 125 is provided on the lock head 1222. During the process of installing the lock head 1222 into the battery housing 221, the stop protrusion 125 can abut against the bottom wall of the receiving groove 222 to position the lock head 1222 and prevent the lock head 1222 from further entering the battery housing 221. This facilitates the locking protrusion 123 being suspended above the battery housing 221, and further facilitates the locking protrusion 123 passing through the hanging hole 211 and engaging with the snap-fit ​​member 112.

[0201] In some embodiments of this application, a stop protrusion 125 is provided on both radial sides of the lock head 1222, and a positioning groove is formed in the receiving groove 222 along its radial direction. The receiving groove 222 is located on both radial sides of the lock head 1222 and is provided in a one-to-one correspondence with the stop protrusion 125. The stop protrusion 125 can be embedded in the positioning groove to restrict the rotational freedom of the lock head 1222, which is beneficial to improve the stability of the lock head 1222 and reduce the risk of the lock head 1222 disengaging from the fixing member due to the rotation of the lock head 1222.

[0202] Please refer to Figure 1 The vehicle 1000 according to the embodiments of this application includes the chassis 200 described above.

[0203] Since the vehicle 1000 includes the aforementioned chassis 200, and the chassis 200 includes the aforementioned locking mechanism 100, it is beneficial to improve the battery swapping efficiency of the vehicle 1000 and to achieve weight reduction and cost reduction of the vehicle 1000.

[0204] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other.

[0205] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
