[0002] In order to improve the energy density of the battery pack, most of the existing battery packs adopt a module-free structure. For power batteries, long copper bars are required for high-voltage electrical connections. In addition, a large number of high-voltage and low-voltage wiring harnesses are generally arranged inside the battery pack to achieve high and low voltage connections. However, since a large number of battery cells are directly arranged in the box, the space inside the box is limited, which makes wiring more difficult. Summary of the invention

[0009] In one of the embodiments, the mounting portion includes a plurality of clamping plates spaced apart in the wiring groove along the Y direction and connected to the base plate, and a clamping portion for clamping the electrical connector is formed between two adjacent clamping plates.

[0010] In one of the embodiments, a limit buckle is provided at one end of each clamping plate away from the base plate along the Z direction to prevent the electrical connector from withdrawing from the clamping portion, and a guide surface inclined toward the clamping portion is provided on the side of the limit buckle facing away from the clamping portion.

[0011] In one of the embodiments, the clamping plate located on at least one side of each of the clamping portions is formed with an arc-shaped protrusion on a side facing the clamping portion.

[0015] A battery module is accommodated in the battery installation cavity, and the height of the battery module is higher than the height of the longitudinal and transverse beams to form a concave cavity for installing the electrical connector fixing seat; and

[0016] The electrical connector is connected to the mounting portion of the electrical connector fixing seat.

[0017] In addition, the present application also provides an electrical device, including a battery pack as described in the above preferred embodiment.

[0036] See also Figure 1 and Figure 6 The present invention provides a battery pack 10. In addition, the present invention also provides an electrical device.

[0037] The above-mentioned electrical equipment includes the above-mentioned battery pack 10, and can be provided with electrical energy by the above-mentioned battery pack 10. Among them, the above-mentioned electrical equipment can be vehicles, spacecraft, electric toys, electric tools, energy storage equipment, and amusement equipment, etc. The vehicle can be a fuel vehicle, a gas vehicle or a new energy vehicle, and the new energy vehicle can be a pure electric vehicle, a hybrid vehicle or an extended-range vehicle, etc.; the spacecraft includes an airplane, a rocket, a space shuttle and a spacecraft, etc.; the electric toys include fixed or mobile electric toys, for example, game consoles, electric car toys, electric ship toys or electric airplane toys, etc.; the electric tools include metal cutting electric tools, grinding electric tools, assembly electric tools and railway electric tools, for example, electric drills, electric grinders, electric wrenches, electric screwdrivers, electric hammers, impact drills, concrete vibrators and electric planers, etc.; the energy storage equipment can be an energy storage wall, a base station energy storage, a container energy storage, etc.; the amusement equipment can be a carousel, a jumping machine, etc. This application does not impose any special restrictions on the above-mentioned electrical equipment.

[0038] For new energy vehicles, the battery pack 10 can be used as a driving power source to replace fossil fuels to provide driving power.

[0039] Please refer again Figure 1 and Figure 2In one embodiment of the present invention, a battery pack 10 includes an electrical connector fixing seat 100 , a box body (not shown), a battery module 300 and an electrical connector 400 .

[0040] The box body has a storage space inside for accommodating the battery module 300. The outer contour of the box body can be designed according to the installation space of the battery pack 10 during actual application. For example, the box body in this embodiment is designed in a square shell shape. The box body is provided with longitudinal and transverse beams 210. One or more longitudinal and transverse beams 210 can be provided, and multiple longitudinal and transverse beams 210 can be arranged parallel to each other or crosswise. The longitudinal and transverse beams 210 can increase the overall strength and modulus of the box body, thereby helping to improve the reliability of the battery pack 10. Moreover, the top wall of the longitudinal and transverse beams 210 is provided with a fixing groove 211, and the electrical connector fixing seat 100 is installed above the longitudinal and transverse beams 210 through the fixing groove 211. In addition, the top wall of the longitudinal and transverse beams 210 is generally provided with holes, grooves and other structures for installing other components.

[0041] The longitudinal and transverse beams 210 divide the interior of the box into a plurality of battery installation cavities (not marked in the figure), and the battery module 300 is accommodated in the battery installation cavity, and the height of the battery module 300 along the Z direction is higher than the height of the longitudinal and transverse beams 210, so a concave cavity 101 for installing the electrical connector fixing seat 100 is enclosed between the longitudinal and transverse beams 210 and the adjacent battery module 300. Each battery module 300 includes a plurality of battery cells, and a plurality of battery cells can be connected in series, in parallel, or in series and in parallel to form a module and then placed in the above-mentioned battery installation cavity. Alternatively, a plurality of battery cells can also be directly placed in the above-mentioned battery installation cavity in a non-module design. At this time, the battery module 300 is only a general term for a plurality of battery cells, and does not refer to a traditional module structure. The above-mentioned battery cell can be a lithium-ion battery, a sodium-ion battery or a magnesium-ion battery, and its external contour can be a cylinder, a flat body, a cuboid or other shapes, but it is not limited thereto. Specifically in this embodiment, the above-mentioned battery cell is a lithium-ion square shell battery.

[0042] The electrical connector 400 is used to electrically connect to the battery module 300 or other components in the battery pack 10. The electrical connector 400 is generally divided into a high-voltage electrical connector and a low-voltage electrical connector. Among them, the high-voltage electrical connector is used to input or output electrical energy, and the low-voltage electrical connector is used to transmit low-voltage electrical signals. The electrical connector 400 can be in various forms, for example, it can be a copper bus or a wiring harness.

[0043] Please also read Figure 3The electrical connector 400 is connected to the electrical connector fixing seat 100, so that the electrical connector fixing seat 100 is arranged in the cavity 101 formed by the longitudinal and transverse beams 210 and the battery module 300. It can be seen that by setting the electrical connector fixing seat 100, the space above the longitudinal and transverse beams 210 can be used to install the electrical connector 400, so that the electrical connector 400 can be arranged along the extension direction of the cavity 101, thereby facilitating wiring.

[0044] Please also read Figure 4 and Figure 5 In one embodiment of the present invention, the electrical connector fixing seat 100 is provided with a fixing portion 111, an elastic abutting portion 112 and a mounting portion 113. The electrical connector 400 is connected to the mounting portion 113 of the electrical connector fixing seat 100. The fixing portion 111 of the electrical connector fixing seat 100 is inserted into the fixing groove 211, and the elastic abutting portion 112 of the electrical connector fixing seat 100 abuts against the surface of the longitudinal and transverse beams 210 to generate elastic deformation. In this way, the fixing portion 111 cooperates with the elastic abutting portion 112 to reliably fix the electrical connector fixing seat 100 on the longitudinal and transverse beams 210.

[0045] The fixing portion 111 can be specifically in the form of a buckle, with a barb. The fixing portion 111 is elastic, and can be elastically deformed during the insertion process of the fixing groove 211 so that the barb can smoothly extend into the fixing groove 211, and restore the deformation when the barb moves to the inner side of the top wall of the longitudinal and transverse beams 210, so that the stop surface of the barb abuts against the inner side of the top wall of the longitudinal and transverse beams 210. In this way, the stop surface of the barb cooperates with the elastic abutting portion 112 to clamp the top wall of the longitudinal and transverse beams 210 along the Z direction, so that the electrical connector fixing seat 100 is reliably fixed to the longitudinal and transverse beams 210.

[0046] More specifically, the distance between the lowest point of the elastic abutting portion 112 and the barb stop surface is less than the wall thickness of the top wall of the longitudinal and transverse beams 210. Thus, the elastic abutting portion 112 can abut against the surface of the longitudinal and transverse beams 210 and generate elastic deformation during the process of the fixing portion 111 being inserted into the fixing groove 211.

[0047] In the present embodiment, the electrical connector fixing seat 100 includes a side plate 110, and a fixing portion 111, an elastic supporting portion 112 and a mounting portion 113 are all arranged on the side plate 110; the side plate 110 is provided with two relatively spaced cutting grooves 102 along the X direction, and the cutting groove 102 extends to the bottom edge of the side plate 110 along the Z direction, and the portion of the side plate 110 located between the two cutting grooves 102 forms a first elastic sheet 110a, and the portion of the side plate 110 located on the side of the cutting groove 102 facing away from the first elastic sheet 110a forms a second elastic sheet 110b; the fixing portion 111 is arranged at the end of the first elastic sheet 110a, and the end of the second elastic sheet 110b is curled into an arc shape to serve as the elastic supporting portion 112.

[0048] The first elastic piece 110a makes the fixing part 111 have greater elasticity, thereby ensuring that the fixing part 111 can be smoothly inserted into the fixing groove 211. The elastic abutting part 112 obtained by curling the end of the second elastic piece 110b is in the shape of an arc plate, which has greater elasticity itself, and the second elastic piece 110b can give the elastic abutting part 112 greater elasticity, so that the elastic abutting part 112 can smoothly undergo elastic deformation to abut against the top wall of the longitudinal and transverse beams 210. Moreover, the contact area between the arc-shaped elastic abutting part 112 and the top wall of the longitudinal and transverse beams 210 is larger, and the abutment is more reliable.

[0049] Specifically in this embodiment, the curling angle of the elastic abutting portion 112 is A, wherein 90°<A<300°. The curling angle A refers to the central angle corresponding to the elastic abutting portion 112. When A is 90 degrees, the elastic abutting portion 112 is just semicircular. When 90°<A<300°, the elastic abutting portion 112 has greater elasticity.

[0050] Furthermore, in this embodiment, there are two side panels 110, which are arranged relatively spaced apart along the Y direction. The electrical connector fixing seat 100 also includes a bottom plate 120. The two bottom plates 120 are connected between the second spring sheets 110b along the Y direction and are located above the elastic supporting portion 112. The bottom plate 120 and the side panels 110 are arranged to form a wiring groove 103 through which the power supply connector 400 passes.

[0051] The two side plates 110 are provided with fixing parts 111 and elastic supporting parts 112, so that the connection between the electrical connector fixing seat 100 and the longitudinal and transverse beams 210 is more firmly established. Moreover, the wiring groove 103 can also store the electrical connector 400, preventing the electrical connector 400 from scattering during the installation process, and further facilitating wiring.

[0052] The specific form of the mounting portion 113 can be set according to the type of the electrical connector 400. For example, please refer to Figure 3 and Figure 4 In one embodiment, the electrical connector 400 is a wire harness. Correspondingly, the mounting portion 113 includes mounting holes 1131 opened in the two first elastic sheets 110a, and the two mounting holes 1131 are staggered.

[0053] The wire harness as the electrical connector 400 can be first tied with a cable tie 20, and then the cable tie 20 is installed in the mounting hole 1131, so as to connect the wire harness to the mounting portion 113. The cable tie 20 for wrapping the high-voltage wire harness is installed in the mounting hole 1131 of one first spring piece 110a, while the cable tie 20 for wrapping the low-voltage wire harness is installed in the mounting hole 1131 of another first spring piece 110a. Since the two mounting holes 1131 are staggered, the distance between the low-voltage wire harness and the high-voltage wire harness can be increased. In this way, the influence of the high-voltage current in the high-voltage wire harness on the low-voltage electrical signal in the low-voltage wire harness can be reduced, thereby reducing the data fluctuation transmitted through the low-voltage wire harness.

[0054] Also, please see Figure 6 and Figure 7 In another embodiment, the electrical connector 400 is a copper busbar. Correspondingly, the specific form of the mounting portion 113 will be different from that of the previous embodiment.

[0055] Please refer to Figure 8 and Fig. 9 In this embodiment, the mounting portion 113 includes a plurality of clamping plates 130 spaced apart in the wiring groove 103 along the Y direction and connected to the bottom plate 120 , and a clamping portion 1132 for clamping the electrical connector 400 is formed between two adjacent clamping plates 130 .

[0056] The number of the clamping plates 130 can be set according to the number of copper bars to be fixed. For example, three clamping plates 130 are arranged in the wiring trough 103, and two clamping parts 1132 are formed in total, so two copper bars can be fixed at the same time. The copper bar as the electrical connector 400 can be passed through the clamping part 1132, and the distance between two adjacent clamping plates 130 is slightly smaller than the thickness of the copper bar. Therefore, when the copper bar passes through the clamping part 1132, the clamping plates 130 on both sides will be squeezed, so that the clamping plates 130 on both sides are elastically deformed to clamp the copper bar.

[0057] Furthermore, in this embodiment, a limit buckle 131 is provided at one end of each clamping plate 130 away from the bottom plate 120 in the Z direction to prevent the electrical connector 400 from withdrawing from the clamping portion 1132, and a guide surface (not shown) inclined toward the clamping portion 1132 is provided on the side of the limit buckle 131 facing away from the clamping portion 1132. The limit buckle 131 can limit the position of the copper busbar to improve the reliability of installation, and the guide surface can guide the copper busbar, thereby facilitating the insertion of the copper busbar into the clamping portion 1132.

[0058] In addition, in this embodiment, the clamping plate 130 located at least on one side of each clamping portion 1132 is formed with an arc-shaped protrusion 132 on the side facing the clamping portion 1132. Specifically, the arc-shaped protrusion 132 may be formed on both clamping plates 130 on both sides of each clamping portion 1132, or only on one clamping plate 130 on one side. Taking the case of three clamping plates 130 as an example, the arc-shaped protrusion 132 may be formed on both sides of the middle clamping plate 130, or only on the two clamping plates 130 located on both sides facing the clamping portion 1132.

[0059] When the copper bar is clamped into the clamping portion 1132 , the clamping plates 130 on both sides may fail to clamp the copper bar due to processing errors and other reasons. However, the arc-shaped protrusions 132 can squeeze the copper bar inward, so that the copper bar is reliably clamped in the clamping portion 1132 .

[0060] When assembling the battery pack 10 and the electrical connector fixing seat 100, the fixing portion 111 can be inserted into the fixing groove 211 on the longitudinal and transverse beams 210 of the box body along the Z direction, and the elastic abutting portion 112 can be abutted against the surface of the longitudinal and transverse beams 210 to generate elastic deformation. The fixing portion 111 cooperates with the elastic abutting portion 112 to fix the electrical connector fixing seat 100 on the longitudinal and transverse beams 210. Electrical connectors 400 such as low-voltage wiring harnesses, high-voltage wiring harnesses and copper busbars can be connected to the mounting portion 113, so that they are arranged in the concave cavity 101 formed by the longitudinal and transverse beams 210 and the battery module 300 through the electrical connector fixing seat 100. It can be seen that the electrical connector fixing seat 100 can use the space above the longitudinal and transverse beams 210 to install the electrical connector 400, thereby facilitating wiring.

[0061] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0062] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
