[0003] The battery modules inside the battery pack need to be connected to each other. The existing connectors for connecting the battery modules inside the battery pack are usually connected to the connecting copper bars of the battery pack by bolts or other methods that are not easy to disassemble. The connection process between the modules inside the battery pack is complicated and not easy to disassemble and install. Utility Model Content

[0004] One of the purposes of the present invention is to provide a connection device to solve the problem of complicated connection process between battery modules in the existing battery pack. The second purpose is to provide a vehicle.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0006] The embodiment of the present application provides a connection device, including a conductive body and a plurality of clamping members. The plurality of clamping members are distributed at both ends of the conductive body. One end of the clamping member is connected to the conductive body, and the other end is formed with a clamping groove.

[0007] According to the above-mentioned technical means, the connection device provided in the embodiment of the present application has multiple clamps distributed at both ends of the conductive body. One end of the clamp is connected to the conductive body, and the other end is formed with a clamping groove. In actual use, the clamps located at both ends of the conductive body can be respectively connected to the two battery modules that need to be connected to each other, so that a passage is formed between the two battery modules that need to be connected to each other. Since the other end of the clamp is formed with a clamping groove, in the actual installation process, the clamps located at both ends of the conductive body can be respectively connected to the connecting copper bars of the two battery modules that need to be connected to each other in the form of plug-in. In this way, the connection process between the battery modules inside the battery pack can be simplified, and it is convenient for the staff to connect the battery modules.

[0008] In some embodiments, the clamping member includes a first clamping member and a second clamping member. One end of the first clamping member is connected to the conductive body. The second clamping member is located on a side of the conductive body away from the first clamping member, and one end is connected to the conductive body. The first clamping member and the second clamping member are arranged with a relative spacing, and the spacing between the first clamping member and the second clamping member forms a clamping groove.

[0009] According to the above technical means, when the connecting device is connected to the connecting copper bars of two battery modules that need to be connected to each other by plugging, the first clamp and the second clamp can be against the two sides of the connecting copper bars of the two battery modules that need to be connected to each other, and the friction between the first clamp and the second clamp and the connecting copper bars of the two battery modules that need to be connected to each other can ensure the stability of the connection between the connecting device and the connecting copper bars of the two battery modules that need to be connected to each other.

[0010] In some embodiments, the first clamp and the second clamp are elastic sheet structures. The first clamp is bent at one end away from the conductive body to form a first protrusion. The second clamp is bent at one end away from the conductive body to form a second protrusion. The first protrusion protrudes toward the direction close to the second clamp, and the second protrusion protrudes toward the direction close to the first clamp.

[0011] According to the above technical means, since the first clamping member and the second clamping member can be elastic sheet structures, the first clamping member and the second clamping member can have good elastic force, and the clamping effect of the first clamping member and the second clamping member is stable. The first protrusion and the second protrusion can ensure that the first clamping member and the second clamping member are in contact with the clamped object, thereby ensuring the clamping effect of the first clamping member and the second clamping member.

[0012] In some embodiments, the connection device further comprises a retaining member, which is connected to the first clamping member and the second clamping member and is used to apply a force to the first clamping member and the second clamping member in a direction of approaching each other.

[0013] According to the above technical means, the retaining member can improve the clamping effect of the first clamping member and the second clamping member, so that the connection between the first clamping member and the second clamping member and the connecting copper bars of the two battery modules that need to be connected to each other is more stable.

[0014] In some embodiments, the first clamping member includes a first connection portion and a plurality of second connection portions; the first connection portion is connected to the conductive body, one end of the second connection portion is connected to the first connection portion, and there are intervals between the plurality of second connection portions. The second clamping member includes a third connection portion and a plurality of fourth connection portions; the third connection portion is connected to the conductive body, one end of the fourth connection portion is connected to the third connection portion, and there are intervals between the plurality of fourth connection portions. The retaining member is clamped in the intervals between the plurality of second connection portions and the intervals between the plurality of fourth connection portions; a portion of the retaining member is located on a side of the plurality of second connection portions away from the plurality of fourth connection portions, and on a side of the plurality of fourth connection portions away from the plurality of second connection portions.

[0015] According to the above technical means, the intervals between the plurality of third connecting parts and the intervals between the plurality of fourth connecting parts can provide installation positions for the retaining member. In the process of clamping the clamping member on the connecting copper bar, the retaining member and the clamping member are located on the same side of the connecting copper bar, which can avoid interference between the retaining member and the connecting copper bar, and facilitate the connection of the clamping member and the connecting copper bar. The retaining member can limit the movement of the second connecting part and the fourth connecting part in the direction away from each other, thereby maintaining the stability of the object clamped by the second connecting part and the fourth connecting part.

[0016] In some embodiments, a plurality of first abutment portions are formed on the retaining member, a portion of the first abutment portions are located on a side of the plurality of second connection portions away from the fourth connection portion, and another portion of the first abutment portions are located on a side of the plurality of fourth connection portions away from the plurality of second connection portions.

[0017] According to the above technical means, multiple first abutting portions can respectively abut against multiple second connecting portions and multiple fourth connecting portions to limit the first clamping member and the second clamping member from moving away from each other, thereby ensuring the stability of the connection between the first clamping member and the second clamping member and the connecting copper busbar.

[0018] In some embodiments, the retaining member is also formed with multiple second abutment portions, which are spaced apart from the first abutment portions; a portion of the second abutment portions is located on the side of the multiple second connection portions away from the fourth connection portions, and another portion of the second abutment portions is located on the side of the multiple fourth connection portions away from the multiple second connection portions.

[0019] According to the above technical means, since the second abutting portion is spaced apart from the first abutting portion, the second abutting portion and the first abutting portion can abut against the plurality of second connecting portions and the plurality of fourth connecting portions from different positions. In this way, the retaining member can apply pressure to the plurality of second connecting portions and the plurality of fourth connecting portions from different positions to bring them closer to each other, and the force can be dispersed to different positions of the plurality of second connecting portions and the plurality of fourth connecting portions, thereby preventing the plurality of second connecting portions and the plurality of fourth connecting portions from being deformed.

[0020] In some embodiments, mounting parts are formed at both ends of the conductive body, and a plurality of clamping members are respectively connected to the mounting parts at both ends of the conductive body. The connecting device also includes an insulating member, which is covered on the outside of the conductive body and located between the two mounting parts.

[0021] According to the above technical means, the insulating member can reduce the area of ​​the conductive body exposed to the outside world, and can reduce the risk of electric shock during installation and maintenance operations. At the same time, the insulating member can also protect the conductive body from being scratched.

[0022] In some embodiments, the connection device further comprises two protection members, which are connected to the conductive body and are respectively disposed around the two mounting portions.

[0023] According to the above technical means, the protective member can form protection around the installation part to reduce the risk of workers touching the installation part.

[0024] The present application also provides a vehicle, comprising the above-mentioned connecting device, which can be connected to a battery module.

Since a clamping groove is formed at the other end of the clamp, in the actual installation process, the clamps at both ends of the conductive body can be respectively connected to the connecting copper bars of the two battery modules that need to be connected to each other by plugging. In this way, the connection process between the battery modules inside the battery pack can be simplified, and it is convenient for the staff to connect the battery modules.

DETAILED DESCRIPTION

[0046] In order to enable ordinary persons in the art to better understand the technical solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings.

[0047] It should be noted that the terms "first"-"second" and the like in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. Instead, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0048] The embodiment of the present application provides a vehicle, which may include a vehicle body and a connecting device. A battery pack may be provided on the vehicle body. The battery pack may include a plurality of battery modules, and the connecting device is used to connect different battery modules to achieve circuit connection between the battery modules.

[0049] Next, the connection device provided in the embodiment of the present application is further introduced. Figure 1 As shown, Figure 1 One of the structural schematic diagrams of the connection device 100 provided in the embodiment of the present application, the connection device 100 may include a conductive body 1 and a plurality of clamps 2. The conductive body 1 may be made of a conductive material, and current may flow in the conductive body 1 and the clamps 2. Exemplarily, the conductive body 1 may be made of copper, so that the conductive body 1 may have good conductive properties. In addition, the size of the conductive body 1 may be adjusted according to actual usage requirements to ensure that the conductive body 1 can meet different current carrying requirements. For example, when the voltage between two battery modules that need to be connected to each other is high and the current passing through is large, the size of the conductive body 1 may be appropriately increased.

[0050] A plurality of clamping members 2 are distributed at both ends of the conductive body 1. One end of the clamping member 2 is connected to the conductive body 1, and the other end is formed with a clamping groove 21. In this way, in actual use, the clamping members 2 located at both ends of the conductive body 1 can be respectively connected to two battery modules that need to be connected to each other, so that a passage is formed between the two battery modules that need to be connected to each other.

[0051] Since the other end of the clamping member 2 is formed with a clamping groove 21, in the actual installation process, Figure 2 As shown, Figure 2 The schematic diagram of the connection device 100 provided in the embodiment of the present application is in use. The clamping members 2 at both ends of the conductive body 1 can be connected to the connecting copper bars of the two battery modules that need to be connected to each other by plugging. In this way, the connection process between the battery modules inside the battery pack can be simplified, and it is convenient for the staff to connect the battery modules.

[0052] In order to improve the corrosion resistance of the conductive body 1, in some embodiments, the surface of the conductive body 1 may be nickel-plated, so that the surface of the conductive body has better corrosion resistance.

[0053] For example, Figure 3 As shown, Figure 3 The second structural diagram of the connection device 100 provided in the embodiment of the present application, the number of the clamping members 2 can be two, along Figure 3 In the left and right directions, the clamping member 2 can be connected to the two ends of the conductive body 1 respectively. It can be understood that in practical applications, the number of the clamping members 2 can be set according to actual needs, and it is only necessary to ensure that the clamping member 2 can play a role in connection and circuit conduction.

[0054] Exemplarily, there may be two clamping members 2 , and the two clamping members 2 may be respectively disposed at two ends of the conductive body 1 . In this case, the connecting device 100 may connect two battery modules that need to be connected to each other.

[0055] In some embodiments, Figure 4 As shown, Figure 4 This is one of the partial structural diagrams of the connection device 100 provided in the embodiment of the present application, the clamping member 2 includes a first clamping member 22 and a second clamping member 23. One end of the first clamping member 22 is connected to the conductive body 1, and the second clamping member 23 is located on the side of the conductive body 1 away from the first clamping member 22, and one end is connected to the conductive body 1. The first clamping member 22 and the second clamping member 23 are arranged relatively spaced apart, and the space between the first clamping member 22 and the second clamping member 23 forms a clamping groove 21.

[0056] When the connecting device 100 is connected to the connecting copper bars of two battery modules that need to be connected to each other by plugging, the first clamp 22 and the second clamp 23 can be against the two sides of the connecting copper bars of the two battery modules that need to be connected to each other, and the friction between the first clamp 22 and the second clamp 23 and the connecting copper bars of the two battery modules that need to be connected to each other can ensure the stability of the connection between the connecting device 100 and the connecting copper bars of the two battery modules that need to be connected to each other.

[0057] In addition, when the first clamping member 22 and the second clamping member 23 are damaged during long-term use, the staff can replace them according to the actual damaged parts without replacing the entire part, which can reduce the maintenance cost of the vehicle.

[0058] In the actual application process, it can be understood that the first clamping member 22 and the second clamping member 23 can be made of copper, so that the first clamping member 22 and the second clamping member 23 can also have good electrical conductivity. In addition, the size of the first clamping member 22 and the second clamping member 23 can also be adjusted according to actual use requirements. For example, the thickness of the first clamping member 22 and the second clamping member 23 can be 0.5 mm to 1.5 mm, so that the first clamping member 22 and the second clamping member 23 can have good elasticity and can also ensure the electrical conductivity.

[0059] In order to ensure the clamping effect of the first clamping member 22 and the second clamping member 23, in some embodiments, as Figure 5 As shown, Figure 5 The schematic diagram of the structure of the clamping member 2 provided in the embodiment of the present application, the first clamping member 22 and the second clamping member 23 can be elastic sheet structures. In this way, the first clamping member 22 and the second clamping member 23 can have good elastic force, and the clamping effect of the first clamping member 22 and the second clamping member 23 is stable.

[0060] Continue to refer to Figure 5 , the first clamping member 22 is away from the conductive body 1 ( Figure 2) is bent to form a first protrusion 221, and one end of the second clamping member 23 away from the conductive body 1 is bent to form a second protrusion 231. The first protrusion 221 protrudes in a direction close to the second clamping member 23, and the second protrusion 231 protrudes in a direction close to the first clamping member 22. The first protrusion 221 and the second protrusion 231 can ensure that the first clamping member 22 and the second clamping member 23 are in contact with the clamped object, thereby ensuring the clamping effect of the first clamping member 22 and the second clamping member 23.

[0061] In actual application, the first protrusion 221 and the second protrusion 231 can be arranged opposite to each other, and the distance between the first protrusion 221 and the second protrusion 231 is less than the thickness of the clamped object. In this way, when the first protrusion 221 and the second protrusion 231 are clamped on both sides of the clamped object, the first clamping member 22 and the second clamping member 23 are in a stretched elastic deformation state, and the reaction force generated by the first clamping member 22 and the second clamping member 23 can increase the friction between the first protrusion 221 and the second protrusion 231 and the clamped object.

[0062] In some embodiments, Figure 6 As shown, Figure 6 The second partial structural diagram of the connection device 100 provided in the embodiment of the present application, the connection device 100 may also include a retaining member 3. The retaining member 3 is connected to the first clamping member 22 and the second clamping member 23, and is used to apply a force toward the first clamping member 22 and the second clamping member 23 in the direction of approaching each other. In this way, the retaining member 3 can improve the clamping effect of the first clamping member 22 and the second clamping member 23, so that the connection between the first clamping member 22 and the second clamping member 23 and the connecting copper busbars of the two battery modules that need to be connected to each other is more stable.

[0063] In some embodiments, Figure 6 As shown, the first clamping member 22 includes a first connecting portion 222 and a plurality of second connecting portions 223. The first connecting portion 222 is connected to the conductive body 1. In this way, the first connecting portion 222 can connect the first clamping member 22 and the conductive body 1 together. One end of the second connecting portion 223 is connected to the first connecting portion 222, and there is a gap between the plurality of second connecting portions 223.

[0064] The second clamping member 23 includes a third connection portion 232 and a plurality of fourth connection portions 233. The third connection portion 232 is connected to the conductive body 1. In this way, the third connection portion 232 can connect the second clamping member 23 and the conductive body 1 together. The third connection portion 232 is connected to the conductive body 1, one end of the fourth connection portion 233 is connected to the third connection portion 232, and the plurality of fourth connection portions 233 are spaced apart from each other.

[0065] like Figure 2 As shown, the retaining member 3 is clamped to a plurality of third connecting portions 232 ( Figure 5 ) and the intervals between the plurality of fourth connection portions 233 ( Figure 5 ). In this way, the intervals between the plurality of third connecting parts 232 and the intervals between the plurality of fourth connecting parts 233 can provide installation positions for the retaining member 3. In the process of clamping the clamping member 2 on the connecting copper bar, the retaining member 3 and the clamping member 2 are located on the same side of the connecting copper bar, which can avoid interference between the retaining member 3 and the connecting copper bar, and facilitate the connection between the clamping member and the connecting copper bar.

[0066] A portion of the retaining member 3 is located on a side of the plurality of second connection parts 223 away from the plurality of fourth connection parts 233, and a side of the plurality of fourth connection parts 233 away from the plurality of second connection parts 223. In this way, the retaining member 3 can limit the second connection parts 223 and the fourth connection parts 233 from moving in a direction away from each other, thereby maintaining the stability of the second connection parts 223 and the fourth connection parts 233 clamping the object.

[0067] For example, Figure 6 As shown, the ends of the first clamping member 22 and the second clamping member 23 away from the conductive body 1 can be a plurality of pins arranged at intervals. A portion of the retaining member 3 is clamped in the intervals between the plurality of pins.

[0068] In some embodiments, Figure 6 As shown, a plurality of first abutting portions 31 are formed on the retaining member 3, a portion of the first abutting portions 31 is located on a side of the plurality of second connecting portions 223 away from the fourth connecting portion 233, and another portion of the first abutting portions 31 is located on a side of the plurality of fourth connecting portions 233 away from the plurality of second connecting portions 223. In this way, the plurality of first abutting portions 31 can abut against the plurality of second connecting portions 223 and the plurality of fourth connecting portions 233, respectively, to limit the first clamping member 22 and the second clamping member 23 from moving in a direction away from each other, thereby ensuring the stability of the connection between the first clamping member 22 and the second clamping member 23 and the connecting copper busbar.

[0069] In some embodiments, Figure 6 As shown, the retaining member 3 is also formed with a plurality of second abutting portions 32, and the second abutting portions 32 are spaced apart from the first abutting portions 31. A portion of the second abutting portions 32 is located on a side of the plurality of second connecting portions 223 away from the fourth connecting portion 233, and another portion of the second abutting portions 32 is located on a side of the plurality of fourth connecting portions 233 away from the plurality of second connecting portions 223. In this way, the second abutting portions 32 can also abut against the plurality of second connecting portions 223 and the plurality of fourth connecting portions 233, respectively, to limit the first clamping member 22 and the second clamping member 23 from moving in a direction away from each other, thereby improving the stability of the connection between the first clamping member 22 and the second clamping member 23 and the connecting copper bar.

[0070] At the same time, since the second abutting portion 32 is spaced apart from the first abutting portion 31, the second abutting portion 32 and the first abutting portion 31 can abut against the plurality of second connecting portions 223 and the plurality of fourth connecting portions 233 from different positions. In this way, the retaining member 3 can apply pressure to the plurality of second connecting portions 223 and the plurality of fourth connecting portions 233 from different positions to approach each other, and the force can be dispersed to different positions of the plurality of second connecting portions 223 and the plurality of fourth connecting portions 233, thereby preventing the plurality of second connecting portions 223 and the plurality of fourth connecting portions 233 from being deformed.

[0071] In some embodiments, Figure 7 As shown, Figure 7 The schematic diagram of the partial structure of the conductive body 1 and the insulating member 6 provided in the embodiment of the present application shows that the conductive body 1 is provided with mounting portions 11 at both ends, and the plurality of clamping members 2 are respectively connected to the mounting portions 11 at both ends of the conductive body 1. The mounting portions 11 can provide mounting positions for the plurality of clamping members 2.

[0072] like Figure 1 As shown, two mounting portions 11 may be formed at both ends of the conductive body 1, and a plurality of clamping members 2 may be respectively connected to the mounting portions 11 at both ends of the conductive body 1. Figure 6 As shown, the mounting portion 11 may be provided with a first connection hole 112, the third connection portion 232 and the first connection portion 222 may be provided with a second connection hole 24, and the connecting device 100 may further include a rivet 5. The rivet 5 penetrates the first connection hole 112 and the second connection hole 24 to connect the first clamping member 22 and the second clamping member 23 to the mounting portion 11 together.

[0073] It is understandable that the clamping member 2 can also be connected to the mounting portion 11 in other ways, and it is only necessary to ensure that the clamping member 2 can be stably connected to the mounting portion 11 during the use of the connecting device 100.

[0074] like Figure 7 As shown, the connection device 100 may further include an insulating member 6, which may be disposed outside the conductive body 1 and between the two mounting portions 11. In actual application, the insulating member 6 may be made of an insulating material, and the insulating member 6 may reduce the area of ​​the conductive body 1 exposed to the outside, and may reduce the risk of electric shock during installation and maintenance operations of the staff. At the same time, the insulating member 6 may also protect the conductive body 1 from being scratched.

[0075] In some embodiments, Figure 6As shown, the connection device 100 may also include two protective members 4. The two protective members 4 are connected to the conductive body 1 and are respectively covered on the circumference of the two mounting portions 11. The protective members 4 may also be made of an insulating material, so that the protective members 4 may form a protection on the circumference of the mounting portion 11, reducing the risk of the staff touching the mounting portion 11. Exemplarily, the protective member 4 may be made of a plastic material. In this way, the protective member 4 has a good insulating effect.

[0076] The above are only specific implementations of the present application, but the protection scope of the present application is not limited thereto, and any changes or substitutions within the technical scope disclosed in the present application should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
