Description

Technical Field

[0001] The present application relates to the field of vehicle technology, and in particular to a buckle auxiliary device, a buckle assembly, a battery pack and a vehicle. Background Art

[0002] As an important component of new energy vehicles, the battery pack plays an important role in providing energy for new energy vehicles. In order to ensure the normal operation of the battery cells in the battery pack, a water cooling system is usually provided on the new energy battery box to cool the battery cells.

[0003] The water spout serves as the inlet and outlet interface of the water cooling system. During the production and transportation of battery packs, a water spout protection cover is installed at the water spout to protect the water spout and prevent pollutants from entering the water cooling system and causing the water pump to be blocked. At the same time, it can prevent the coolant from leaking from the water spout.

[0004] However, after the existing faucet protection cover (first component) and the faucet (second component) are installed, they are prone to loosening or even falling off, and cannot produce a good protection effect. Summary of the invention

[0005] The purpose of the present application is to provide a buckle auxiliary device, a buckle assembly, a battery pack and a vehicle, aiming to solve the problem that the first component and the second component are easily loosened or dropped after installation.

[0006] In order to achieve the above object, the present invention adopts the following technical scheme:

[0007] In a first aspect, the present application provides a snap-on auxiliary device for assisting the snap to connect a first component and a second component. The snap-on auxiliary device may include an elastic support member, a first abutment member and a second abutment member, wherein the first abutment member and the second abutment member are arranged at intervals, the elastic support member is elastically connected between the first abutment member and the second abutment member, the first abutment member is used to abut against the first component, and the second abutment member is used to abut against the snap.

[0008] Since the elastic support member is elastically connected between the first abutment member and the second abutment member, it can provide a supporting force to the first abutment member and the second abutment member, thereby ensuring that the first abutment member abuts against the first component and the second abutment member abuts against the buckle, and then the buckle auxiliary device can form an interference fit with the gap between the first component and the buckle. In this way, the buckle auxiliary device can make the buckle tightly connected with the slot on the second component, thereby effectively reducing the loosening or falling between the first component and the second component.

[0009] In some embodiments, the buckle auxiliary device may further include a first limiter, which may be connected to the second abutment member and abut against the buckle. In this way, the first limiter may limit the buckle auxiliary device to prevent the buckle auxiliary device from falling off between the first component and the buckle.

[0010] In some embodiments, the first position-limiting member includes a first protrusion, and a side wall of the first protrusion can abut against the buckle. In this way, when the buckle auxiliary device slides between the first component and the buckle, the first side wall of the first protrusion abuts against the edge of the buckle, thereby limiting the position of the buckle auxiliary device and preventing the buckle auxiliary device from falling off between the first component and the buckle.

[0011] In some embodiments, the buckle auxiliary device may further include a connecting member, which is connected between the first abutting member and the second abutting member and is spaced apart from the elastic supporting member. In this way, the connecting member and the elastic supporting member can both provide supporting force to the first abutting member and the second abutting member, thereby preventing the first abutting member and the second abutting member from being damaged.

[0012] In some embodiments, the elastic support member is tilted between the first abutment member and the second abutment member. In this way, the elastic support member can provide support force for the first abutment member and the second abutment member while being elastically deformed, thereby adjusting the support force of the elastic support member according to the position change of the buckle auxiliary device, so that the first abutment member and the second abutment member can clamp the buckle and the first component, thereby reducing the loosening or falling off between the first component and the second component.

[0013] In some embodiments, along the direction from the elastic support member to the connecting member, the gap between at least part of the first abutting member and the second abutting member gradually decreases. In this way, by adjusting the position of the buckle auxiliary device, it can form different cooperation with the buckle and the first component, thereby achieving locking and loosening of the buckle and the first component, which is convenient for operation.

[0014] In some embodiments, the second abutment member includes a first plate body, a second plate body and a first bent connection portion, wherein the first plate body is connected to the elastic support member, the second plate body is connected to the connecting member, one end of the first bent connection portion is connected to the first plate body, and the other end of the first bent connection portion is bent toward one end close to the first abutment member and connected to the second plate body.

[0015] Since the gap between at least part of the first abutment member and the second abutment member gradually decreases along the direction from the elastic support member to the connecting member, the gap between the first plate body and the first abutment member can be larger than the gap between the second plate body and the first abutment member.

[0016] In this way, when the first plate is located between the buckle and the first component, the buckle auxiliary device and the gap between the buckle and the first component can form an interference fit due to the supporting effect of the elastic support member, so that the buckle and the second component are clamped tightly, and the first component is not easy to fall off the second component. When the second plate is located between the buckle and the first component, the gap between the first abutment member and the second plate is reduced, so that the buckle auxiliary device and the gap between the buckle and the first component can form a clearance fit, so that the buckle and the second component can be loosened, and the first component is easy to be removed from the second component.

[0017] In some embodiments, the first stopper is connected to an end of the first plate away from the first bent connection portion. In this way, the first stopper can prevent the buckle auxiliary device from sliding off between the buckle and the first component without interfering with the movement from the first plate to the second plate, thereby allowing the buckle and the first component to switch smoothly from a locked state to a released state.

[0018] In some embodiments, the first abutment member includes a third plate body, a fourth plate body and a second bent connection portion, the third plate body is connected to the elastic support member, the fourth plate body is connected to the connecting member, one end of the second bent connection portion is connected to the third plate body, and the other end of the second bent connection portion is bent toward one end close to the second abutment member and connected to the fourth plate body.

[0019] In this way, when the first plate and the third plate are located between the buckle and the first component, due to the supporting effect of the elastic support member, the buckle auxiliary device and the gap between the buckle and the first component can form an interference fit, thereby clamping the buckle and the second component, and the first component is not easy to fall off from the second component. When the second plate and the fourth plate are located between the buckle and the first component, due to the reduction of the gap between the second plate and the fourth plate, the buckle auxiliary device and the gap between the buckle and the first component can form a clearance fit, thereby loosening the buckle and the second component, and facilitating the removal of the first component from the second component.

[0020] In some embodiments, the buckle auxiliary device may further include an elastic stopper, which is disposed on the second plate and can abut against at least a portion of the first component. In this way, when the first plate and the third plate are located between the buckle and the first component, the elastic stopper can abut against at least a portion of the first component, thereby preventing the second plate from sliding into the gap between the buckle and the first component, causing the first component to loosen or slide off the second component.

[0021] In some embodiments, the elastic stopper may include a second protrusion, which is protruding from the second side wall of the second plate. In this way, when the first plate and the third plate are located between the buckle and the first component, the second protrusion abuts against the first component, thereby limiting the buckle auxiliary device and preventing the second plate from sliding into the gap between the buckle and the first component.

[0022] In some embodiments, there is a movable gap between at least part of the second protrusion and the second plate body. Thus, when the buckle auxiliary device is transformed from a locked state to a loosened state, the second protrusion can be elastically deformed by a worker applying a thrust to the second plate body, thereby sinking into the movable gap, so that the second plate body enters the gap between the buckle and the first component, thereby loosening the buckle and the first component, and facilitating the removal of the first component.

[0023] In some embodiments, the snap-on auxiliary device may include a first supporting foot, a second supporting foot and a pushing member, the first supporting foot and the second supporting foot each include an elastic supporting member, a first abutting member and a second abutting member, and at least a portion of the pushing member is connected between the first supporting foot and the second supporting foot.

[0024] In this way, the first supporting leg and the second supporting leg can both be used to form an interference fit with the gap between the first component and the buckle, so that the buckle is tightly connected to the clamping groove on the second component, further reducing the looseness or falling between the first component and the second component. At least part of the pusher is connected between the first supporting leg and the second supporting leg, which can facilitate the simultaneous pushing of the first supporting leg and the second supporting leg of the buckle auxiliary device into the gap between the first component and the buckle, making it easier for the operator to operate.

[0025] In the second aspect, the present application further provides a buckle assembly, including a buckle body and the above-mentioned buckle auxiliary device, the buckle auxiliary device is used to assist the buckle body in connecting the first component and the second component. It should be noted that the technical effects brought about by the implementation of the second aspect can refer to the technical effects brought about by the corresponding implementation in the first aspect, and will not be repeated here.

[0026] In a third aspect, the present application further provides a battery pack, including the above-mentioned buckle assembly. It should be noted that the technical effects brought about by the implementation of the third aspect can refer to the technical effects brought about by the corresponding implementations in the first and second aspects, and will not be repeated here.

[0027] In some embodiments, the battery pack may further include a faucet and a faucet protective cover, wherein the faucet constitutes at least a portion of the second component, the faucet protective cover constitutes at least a portion of the first component, and the snap body is disposed between the first component and the second component.

[0028] Since the snap body is arranged between the first component and the second component, the snap body can connect the faucet protective cover and the faucet, and the snap auxiliary device can form an interference fit with the gap between the faucet protective cover and the snap body, so that the snap body and the faucet can be tightly connected, thereby effectively reducing the loosening or falling between the faucet protective cover and the faucet.

[0029] In some embodiments, the faucet protection cover and the buckle body are an integrated structure, which can reduce the number of parts and components, thereby reducing the difficulty of material management.

[0030] In a fourth aspect, the present application further provides a vehicle, comprising the above-mentioned battery pack. It should be noted that the technical effects brought about by the implementation of the fourth aspect can refer to the technical effects brought about by the corresponding implementation in the third aspect, which will not be repeated here.

[0045] As an important component of new energy vehicles, the battery pack plays an important role in providing energy for new energy vehicles. In order to ensure the normal operation of the battery cells in the battery pack, a water cooling system is usually provided on the new energy battery box to cool the battery cells.

[0046] The water spout serves as the inlet and outlet interface of the water cooling system. During the production and transportation of battery packs, the water spout is easily damaged by squeezing or friction. Therefore, a water spout protection cover is provided at the water spout to protect the water spout from being worn or squeezed by other components. At the same time, the water spout protection cover can prevent pollutants from entering the water cooling system and causing blockage of the water pump.

[0047] The existing faucet protection cover is connected to the faucet through a buckle. However, when the buckle is buckled, the faucet protection cover is easy to loosen or even fall off, and cannot provide a good protection effect for the faucet.

[0048] Based on this, an embodiment of the present application provides a snap-on auxiliary device, by making the first abutment piece of the snap-on auxiliary device abut against the faucet protective cover, and the second abutment piece abut against the buckle, the gap between the snap-on auxiliary device and the buckle and the faucet protective cover can be interference fit, so that the buckle can clamp the faucet, thereby preventing the faucet protective cover from falling off the faucet.

[0049] Please refer to Figure 1 , Figure 2 and Figure 3 , Figure 1 This is one of the structural schematic diagrams of a buckle auxiliary device 100 provided in an embodiment of the present application. Figure 2 A schematic diagram of the structure of a battery pack 1000 provided in an embodiment of the present application is shown in FIG. Figure 3 for Figure 2 A cross-sectional view of a battery pack 1000 is shown.

[0050] The buckle 01 is connected between the first component 02 and the second component 03 , wherein the second component 03 has a slot, and the buckle 01 is buckled into the slot, so that the first component 02 can be fixedly connected to the second component 03 .

[0051] It should be noted that the first component 02 and the second component 03 can be any two parts that need to be detachably connected, and the first component 02 and the second component 03 include but are not limited to any two detachably connected parts on the vehicle, for example, the detachable connection between the vehicle interior panel and the vehicle body, the detachable connection between the battery pack and the battery pack shell, or the detachable connection between the faucet 031 and the faucet protective cover 021, which is not limited in the present application.

[0052] Due to the gap between the buckle 01 and the first component 02 , during the production or transportation process, the buckle 01 and the slot on the second component 03 may become loose, causing the first component 02 to fall off from the second component 03 .

[0053] The buckle auxiliary device 100 provided in the embodiment of the present application can be used to assist the buckle 01 in connecting the first component 02 with the second component 03. The buckle auxiliary device 100 may include an elastic support member 10, a first abutment member 20 and a second abutment member 30, wherein the first abutment member 20 and the second abutment member 30 are arranged at intervals, the elastic support member 10 is elastically connected between the first abutment member 20 and the second abutment member 30, the first abutment member 20 is used to abut against the first component 02, and the second abutment member 30 is used to abut against the buckle 01.

[0054] Since the elastic support member 10 is elastically connected between the first abutment member 20 and the second abutment member 30, it can provide supporting force to the first abutment member 20 and the second abutment member 30, thereby ensuring that the first abutment member 20 abuts against the first component 02, and the second abutment member 30 abuts against the buckle 01, so that the buckle auxiliary device 100 can form an interference fit with the gap between the first component 02 and the buckle 01.

[0055] In this way, the buckle auxiliary device 100 can tightly connect the buckle 01 with the buckle slot on the second component 03, thereby effectively reducing the loosening or falling between the first component 02 and the second component 03.

[0056] In order to prevent the buckle auxiliary device 100 from slipping out in the gap between the first component 02 and the buckle 01, in some embodiments of the present application, the buckle auxiliary device 100 may also include a first limiting member 40, which may be connected to the second abutting member 30, and the first limiting member 40 may abut against the buckle 01.

[0057] In this way, the first limiting member 40 can limit the buckle auxiliary device 100 to prevent the buckle auxiliary device 100 from falling off between the first component 02 and the buckle 01.

[0058] Please refer to Figure 1 , Figure 2 and Figure 4 , Figure 4 for Figure 1 The top view of the buckle auxiliary device 100 is shown. In some embodiments of the present application, the first limit member 40 includes a first protrusion 41, and the first side wall 401 of the first protrusion 41 can abut against the buckle 01.

[0059] In this way, when the buckle auxiliary device 100 slides between the first component 02 and the buckle 01, the first side wall 401 of the first protrusion 41 abuts against the edge of the buckle 01, thereby limiting the buckle auxiliary device 100 and preventing the buckle auxiliary device 100 from falling off from between the first component 02 and the buckle 01.

[0060] In addition, since the elastic support member 10 can be elastically connected to the first abutment member 20 and the second abutment member 30 , the buckle auxiliary device 100 can elastically deform the elastic support member 10 so that the first protrusion 41 passes through the gap between the buckle 01 and the first component 02 .

[0061] In some embodiments of the present application, the buckle auxiliary device 100 may further include a second limit member, which may be connected to the first abutment member 20 , and the second limit member may also include a protrusion, and the side wall of the protrusion may abut against the first component 02 .

[0062] In this way, when the buckle auxiliary device 100 slides between the first component 02 and the buckle 01, the side wall of the protrusion abuts against the edge of the first component 02, thereby limiting the buckle auxiliary device 100 and further preventing the buckle auxiliary device 100 from falling off from between the first component 02 and the buckle 01.

[0063] In order to prevent the first abutment 20 and the second abutment 30 from irreversibly deforming or breaking due to pressure, in some embodiments of the present application, the buckle auxiliary device 100 may also include a connecting member 50, which is connected between the first abutment 20 and the second abutment 30 and is spaced apart from the elastic support member 10.

[0064] In this way, the connecting member 50 and the elastic supporting member 10 can both provide supporting force to the first abutting member 20 and the second abutting member 30, thereby preventing the first abutting member 20 and the second abutting member 30 from being damaged.

[0065] In some embodiments of the present application, the elastic support member 10 is obliquely disposed between the first abutment member 20 and the second abutment member 30. In this way, the elastic support member 10 can provide support force for the first abutment member 20 and the second abutment member 30 while being easy to elastically deform, thereby adjusting the support force of the elastic support member 10 according to the position change of the buckle auxiliary device 100, so that the first abutment member 20 and the second abutment member 30 can clamp the buckle 01 and the first component 02, thereby reducing the looseness or falling off between the first component 02 and the second component 03.

[0066] In some embodiments of the present application, along the direction from the elastic supporting member 10 to the connecting member 50 , the gap between at least part of the first abutting member 20 and the second abutting member 30 gradually decreases.

[0067] In this way, when one end of the buckle auxiliary device 100 close to the elastic support member 10 is located between the buckle 01 and the first component 02, due to the supporting effect of the elastic support member 10, the first abutment member 20 can abut against the first component 02, and the second abutment member 30 can abut against the buckle 01, so that the buckle auxiliary device 100 forms an interference fit with the gap between the buckle 01 and the first component 02, thereby clamping the buckle 01 and the second component 03, and the first component 02 is not easy to fall off from the second component 03.

[0068] When one end of the buckle auxiliary device 100 close to the connecting member 50 is located between the buckle 01 and the first component 02, since the gap between at least part of the first abutment member 20 and the second abutment member 30 is reduced, the buckle auxiliary device 100 can form a clearance fit with the gap between the buckle 01 and the first component 02, thereby loosening the buckle 01 and the second component 03, making it easier to remove the first component 02 from the second component 03.

[0069] In this way, by adjusting the position of the buckle auxiliary device 100, it can form different cooperation with the buckle 01 and the first component 02, thereby realizing the locking and loosening of the buckle 01 and the first component 02, which is easy to operate.

[0070] In some embodiments of the present application, the second abutment member 30 includes a first plate body 31, a second plate body 32 and a first bent connection portion 33, wherein the first plate body 31 is connected to the elastic support member 10, the second plate body 32 is connected to the connecting member 50, one end of the first bent connection portion 33 is connected to the first plate body 31, and the other end of the first bent connection portion 33 is bent toward one end close to the first abutment member 20 and connected to the second plate body 32.

[0071] In this way, since the gap between at least part of the first abutment member 20 and the second abutment member 30 gradually decreases along the direction from the elastic support member 10 to the connecting member 50, the gap between the first plate body 31 and the first abutment member 20 can be made larger than the gap between the second plate body 32 and the first abutment member 20.

[0072] In this way, when the first plate body 31 is located between the buckle 01 and the first component 02, due to the supporting effect of the elastic support member 10, the buckle auxiliary device 100 can form an interference fit with the gap between the buckle 01 and the first component 02, thereby clamping the buckle 01 and the second component 03, and the first component 02 is not easy to fall off from the second component 03.

[0073] When the second plate body 32 is located between the buckle 01 and the first component 02, the gap between the first abutment member 20 and the second plate body 32 is reduced, so that the buckle auxiliary device 100 can form a clearance fit with the gap between the buckle 01 and the first component 02, thereby loosening the buckle 01 and the second component 03, making it easier to remove the first component 02 from the second component 03.

[0074] In some embodiments, the first limiting member 40 is connected to an end of the first plate 31 away from the first bending connection portion 33 .

[0075] In this way, the first limit member 40 can prevent the buckle auxiliary device 100 from slipping between the buckle 01 and the first component 02 without interfering with the movement from the first plate body 31 to the second plate body 32, thereby allowing the buckle 01 and the first component 02 to switch smoothly from a locked state to a released state.

[0076] In some embodiments of the present application, the first abutment member 20 includes a third plate body 21, a fourth plate body 22 and a second bent connection portion 23, the third plate body 21 is connected to the elastic support member 10, the fourth plate body 22 is connected to the connecting member 50, one end of the second bent connection portion 23 is connected to the third plate body 21, and the other end of the second bent connection portion 23 is bent toward one end close to the second abutment member 30 and is connected to the fourth plate body 22.

[0077] In this way, when the first plate body 31 and the third plate body 21 are located between the buckle 01 and the first component 02, due to the supporting effect of the elastic support member 10, the buckle auxiliary device 100 can form an interference fit with the gap between the buckle 01 and the first component 02, thereby clamping the buckle 01 and the second component 03, and the first component 02 is not easy to fall off from the second component 03.

[0078] When the second plate 32 and the fourth plate 22 are located between the buckle 01 and the first component 02, the gap between the second plate 32 and the fourth plate 22 is reduced, so that the buckle auxiliary device 100 can form a clearance fit with the gap between the buckle 01 and the first component 02, thereby loosening the buckle 01 and the second component 03, making it easier to remove the first component 02 from the second component 03.

[0079] Since the first limiting member 40 is connected to one end of the first plate 31 away from the first bent connection portion 33, the buckle auxiliary device 100 can be prevented from slipping from between the buckle 01 and the first component 02, but it cannot be prevented from sliding to a relaxed state when the buckle auxiliary device 100 is in a locked state, thereby causing the first component 02 to loosen or slip from the second component 03.

[0080] Therefore, please refer to Figure 2 and Figure 5 , Figure 5 for Figure 1 The second structural schematic diagram of the snap-on auxiliary device 100 is shown. In some embodiments of the present application, the snap-on auxiliary device 100 may also include an elastic limiter 60, which is arranged on the second plate 32, and the elastic limiter 60 can abut against at least part of the first component 02.

[0081] In this way, when the first plate body 31 and the third plate body 21 are located between the buckle 01 and the first component 02, the elastic limit member 60 can abut against at least part of the first component 02, thereby preventing the second plate body 32 from sliding into the gap between the buckle 01 and the first component 02, causing the first component 02 to loosen or slip off the second component 03.

[0082] In some embodiments, the elastic stopper 60 may include a second protrusion 61 , and the second protrusion 61 is protruded from the second side wall 321 of the second plate body 32 .

[0083] In this way, when the first plate body 31 and the third plate body 21 are located between the buckle 01 and the first component 02, the second protrusion 61 abuts against the first component 02, thereby limiting the buckle auxiliary device 100 and preventing the second plate body 32 from sliding into the gap between the buckle 01 and the first component 02.

[0084] Since the second protrusion 61 is protruded from the second side wall 321 of the second plate body 32, the second plate body 32 is prevented from sliding into the gap between the buckle 01 and the first component 02, which may make it difficult for the buckle auxiliary device 100 to switch from a locked state to a released state. Therefore, in some embodiments of the present application, there is a movable gap between at least a portion of the second protrusion 61 and the second plate body 32.

[0085] In this way, when the buckle auxiliary device 100 is converted from a locked state to a relaxed state, the staff applies a thrust to the second plate body 32, and the second protrusion 61 can undergo elastic deformation, thereby sinking into the movable gap, allowing the second plate body 32 to enter the gap between the buckle 01 and the first component 02, thereby loosening the buckle 01 and the first component 02, making it easier to remove the first component 02.

[0086] In order to facilitate the second protrusion 61 to enter between the buckle 01 and the first component 02, in some embodiments, the second protrusion 61 can be arc-shaped. In this way, due to the guiding effect of the arc surface, when a thrust is applied to the second plate 32, it is easier to enter between the buckle 01 and the first component 02 without causing scratches or damage to the first component 02.

[0087] Since the second protrusion 61 is protrudingly disposed on the second side wall 321 of the second plate body 32, when entering between the buckle 01 and the first component 02, the second protrusion 61 can abut against at least a portion of the first component 02 to form an interference fit in the protruding direction. In this way, when the first component 02 is removed, the buckle auxiliary device 100 will not fall off the first component 02, thereby reducing the difficulty of material management in the factory.

[0088] Please refer to Figure 1 to Figure 5 In some embodiments of the present application, the buckle auxiliary device 100 may include a first supporting foot 110, a second supporting foot 120 and a pushing member 130, the first supporting foot 110 and the second supporting foot 120 both include an elastic supporting member 10, a first abutting member 20 and a second abutting member 30, and at least a portion of the pushing member 130 is connected between the first supporting foot 110 and the second supporting foot 120.

[0089] In this way, the first support leg 110 and the second support leg 120 can both be used to form an interference fit with the gap between the first component 02 and the buckle 01, so that the buckle 01 is tightly connected to the clamping groove on the second component 03, further reducing the looseness or falling between the first component 02 and the second component 03. At least part of the pusher 130 is connected between the first support leg 110 and the second support leg 120, which can facilitate the first support leg 110 and the second support leg 120 of the buckle auxiliary device 100 to be pushed into the gap between the first component 02 and the buckle 01 at the same time, which is convenient for the staff to operate.

[0090] When the buckle auxiliary device 100 is used, the initial state is that the first component 02 and the second component 03 are buckled together by the buckle 01 , and the buckle auxiliary device 100 is separated from the buckle 01 , the first component 02 and the second component 03 .

[0091] Align the end of the snap-on auxiliary device 100 away from the connecting member 50 with the gap between the first component 02 and the buckle 01, apply a thrust to the snap-on auxiliary device 100 along the direction from the connecting member 50 to the elastic support member 10, and when the first plate body 31 and the third plate body 21 are pushed to the gap between the first component 02 and the buckle 01, the first component 02 and the second component 03 can be locked.

[0092] When the first component 02 and the second component 03 need to be disassembled, a thrust is applied to the buckle auxiliary device 100 again along the direction from the connecting member 50 to the elastic support member 10. When the second protrusion 61 is pushed to the gap between the first component 02 and the buckle 01, the first component 02 and the second component 03 can be loosened.

[0093] In this way, during the operation, the staff only needs to push in one direction to complete the locking and loosening transition of the first component 02 and the second component 03, thereby simplifying the operation process.

[0094] The embodiment of the present application further provides a buckle assembly, which may include a buckle body 011 and the above-mentioned buckle auxiliary device 100 , and the buckle auxiliary device 100 is used to assist the buckle body 011 in connecting the first component 02 and the second component 03 .

[0095] Please refer to Figure 2 to Figure 5 , an embodiment of the present application further provides a battery pack 1000, which may include a snap assembly.

[0096] In some embodiments of the present application, the battery pack 1000 may further include a faucet protection cover 021 and a faucet 031, wherein the faucet 031 constitutes at least a portion of the second component 03, the faucet protection cover 021 constitutes at least a portion of the first component 02, and the snap body 011 is disposed between the first component 02 and the second component 03.

[0097] Since the snap body 011 is arranged between the first component 02 and the second component 03, the snap body 011 can connect the faucet protection cover 021 and the faucet 031, and the snap auxiliary device 100 can form an interference fit with the gap between the faucet protection cover 021 and the snap body 011, so that the snap body 011 and the faucet 031 can be tightly connected, thereby effectively reducing the loosening or falling between the faucet protection cover 021 and the faucet 031.

[0098] It can be understood that in other embodiments of the present application, the battery pack 1000 as a whole can constitute at least a part of the first component 02, and the structural member connected to the battery pack 1000 constitutes at least a part of the second component 03. Exemplarily, the structural member connected to the battery pack 1000 can be a battery pack shell or a battery pack base, etc., which is not limited in the present application.

[0099] The battery pack 1000 can be connected to the structural member via the buckle body 011, and the buckle auxiliary device 100 is connected between the buckle body 011 and the battery pack 1000 to assist the buckle body 011 in fastening the battery pack 1000 to the structural member. In this way, the buckle assembly can reduce the shaking between the battery pack 1000 and the structural member.

[0100] In some embodiments of the present application, the faucet protection cover 021 and the buckle body 011 are an integrated structure, which can reduce the number of parts and components, thereby reducing the difficulty of material management.

[0101] The embodiment of the present application also provides a vehicle, which may include the above-mentioned battery pack. In this way, it is possible to prevent the faucet protection cover 021 from falling off from the faucet 031, thereby preventing the faucet from being damaged or the water cooling system from being polluted.
