The electrical component is connected to one side of the battery module. The electrical component includes: a panel having a connection portion; a limiting member detachably disposed on the panel. An installation space is defined between the limiting member and the connection portion. The limiting member is provided with a first positioning portion extending into the installation space; a connection terminal having a second positioning portion. Through the cooperation of the first positioning portion and the second positioning portion, the connection terminal is allowed to extend into the installation space to be connected to the connection portion.

[0006] In the battery device according to the present application, the first positioning portion is provided on the limiting member, and the second positioning portion is provided on the connection terminal. Through the cooperation of the first positioning portion and the second positioning portion, the connection terminal is allowed to extend into the installation space, realizing the anti-fooling function during the assembly of the connection terminal.

[0007] In some embodiments, the first positioning portion includes a positioning protrusion provided on the limiting member, and the second positioning portion includes a recessed area provided on the connection terminal. The recessed area is used to avoid the positioning protrusion, allowing the connection terminal to extend into the installation space.

[0008] In this embodiment, by providing that the first positioning portion includes a positioning protrusion and the second positioning portion includes a recessed area, the setting method of the positioning protrusion and the recessed area is simple, and thus the processing method of the limiting member and the connection terminal is simple.

[0009] In some embodiments, the positioning protrusion is an annular plate-like structure.

[0010] In this embodiment, by setting the positioning protrusion as an annular plate-like structure, when the limiting member is installed on the panel, the positioning protrusion can play a role in cooperating with the recessed area, and can also reduce the weight of the limiting member, thereby reducing the cost of the limiting member.

[0011] In some embodiments, the connection terminal includes a first connection end and a second connection end connected along a first direction. The first connection end is located at an end of the second connection end away from the connection line for connecting to the connection portion. In a second direction, the thickness of the second connection end is greater than that of the first connection end, and the first connection end is disposed on a side close to the second connection end, so that a recessed area is formed on the other side close to the second connection end between the first connection end and the second connection end.

The annular rib abuts against the inner peripheral wall of the installation cavity.

[0020] In this embodiment, by providing an annular rib on the limiting member, at least part of the annular rib extends into the installation cavity and abuts against the inner peripheral wall of the installation cavity, which can tightly seal the first opening and prevent water or dust in the external environment from entering the installation cavity, and can improve the safety when the connecting terminal is connected to the connecting portion.

[0021] In some embodiments, the first positioning portion is spaced apart from the annular rib.

[0022] In this embodiment, by setting the first positioning portion to be spaced apart from the annular rib, the structural strength of the limiting member can be increased.

[0023] In some embodiments, the limiting member includes a limiting body. Both the annular rib and the first positioning portion are connected to a side of the limiting body facing the connecting portion.

An installation space is defined between the connecting portion of the limiting member and the panel. The limiting member is provided with a first positioning portion extending into the installation space; the connection terminal has a second positioning portion. Through the cooperation of the first positioning portion and the second positioning portion, the connection terminal is allowed to extend into the installation space to be connected to the connecting portion, realizing the anti-fooling function during the assembly of the connection terminal.

The vehicle 100 can be a new energy vehicle, and the new energy vehicle can be a pure electric vehicle, a hybrid vehicle, an extended-range vehicle, or the like. A battery device 101 is disposed inside the vehicle 100, and the battery device 101 can be disposed at the bottom, the head, or the tail of the vehicle 100.

[0058] In some embodiments of the present application, the battery device 101 can not only be used as an operating power source of the vehicle 100, but also be used as a driving power source of the vehicle 100, replacing or partially replacing fuel or natural gas to provide driving power for the vehicle 100.

[0059] Figure 2 is a schematic diagram of an electrical component 10 according to some embodiments of the present application, Figure 3 is a schematic diagram of the separation of the limiting member 30 and the panel 20 according to some embodiments of the present application, Figure 4 is a front view of the panel 20 according to some embodiments of the present application, Figure 5 is Figure 4 a cross-sectional view taken along line A-A in Figure 6 is a front view of the panel 20 according to some other embodiments of the present application, Figure 7 is Figure 6 a cross-sectional view taken along line B-B in Figure 8 is a perspective view of the limiting member 30 according to some embodiments of the present application, Figure 9 is a perspective view of the connection terminal 40 according to some embodiments of the present application.

[0060] According to the battery device 101 of the first aspect of the present application, the battery device 101 includes: a battery module and an electrical component 10. The electrical component 10 is connected to one side of the battery module. The electrical component 10 includes: a panel 20, and the panel 20 has a connecting portion 21; a limiting member 30, the limiting member 30 is detachably arranged on the panel 20, and an installation space 34 is defined between the limiting member 30 and the connecting portion 21. The limiting member 30 is provided with a first positioning portion extending into the installation space 34; a connection terminal 40, the connection terminal 40 has a second positioning portion. Through the cooperation of the first positioning portion and the second positioning portion, the connection terminal 40 is allowed to extend into the installation space 34 to be connected to the connecting portion 21.

[0061] Exemplarily, the electrical component 10 is connected to one side of the battery module. The electrical component 10 can be used to collect the current of the battery module and supply it to the electrical device. The electrical component 10 includes a connection terminal 40. The current of the electrical component 10 is supplied to the electrical device through the connection terminal 40. One end of the connection terminal 40 is connected to the connecting portion 21 of the panel 20, and the other end is connected to the connection line of the electrical device. For example. The connection terminal 40 is a high-voltage terminal.

[0062] When the connection terminal 40 is connected to the connecting portion 21, it has a fixed installation posture. If the connection terminal 40 is not connected to the connecting portion 21 in a fixed installation posture, it may cause the connection terminal 40 to be not installed in place, resulting in a connection abnormality between the connection terminal 40 and the connecting portion 21, and further causing the connection terminal 40 to fail to work properly. In the present application, the limiting member 30 is provided with a first positioning portion, and the connection terminal 40 is provided with a second positioning portion. Through the cooperation of the first positioning portion and the second positioning portion, the connection terminal 40 is allowed to extend into the installation space 34 to be connected to the connecting portion 21; if the connection terminal 40 does not extend into the installation space 34 in a fixed installation posture, resulting in the first positioning portion and the second positioning portion not being in a cooperative state, the first positioning portion will block the connection terminal 40 from extending into the installation space 34, and further causing the connection terminal 40 to be unable to be connected to the connecting portion 21 of the panel 20.

[0063] In a specific example, the first positioning portion may be a positioning protrusion 32 provided on the limiting member 30, and the second positioning portion may be a positioning groove provided on the connection terminal 40, and the positioning protrusion 32 may be located within the positioning groove; the first positioning portion may also be a hook provided on the limiting member 30, and the second positioning portion may also be a card slot provided on the limiting member 30, and the hook may be located within the card slot. When the connection terminal 40 moves towards the installation space 34 in a fixed installation posture, the positioning protrusion 32 may be located within the positioning groove of the connection terminal 40. When the connection terminal 40 moves towards the installation space 34 in other postures, the positioning protrusion 32 may block the connection terminal 40 from moving towards the installation space 34; when the connection terminal 40 moves towards the installation space 34 in a fixed installation posture, the hook may be located within the card slot of the connection terminal 40. When the connection terminal 40 moves towards the installation space 34 in other postures, the hook may block the connection terminal 40 from moving towards the installation space 34, thereby preventing the connection terminal 40 from being reversely inserted into the installation space 34 and realizing the anti-fooling function during the assembly of the connection terminal 40.

[0064] In another specific example, the panel 20 is provided with two connection portions 21, one being a positive connection portion and the other being a negative connection portion. Correspondingly, there are two connection terminals 40, one being a positive connection terminal and the other being a negative connection terminal. There are two limiting members 30, and one limiting member 30 restricts the installation posture of the positive connection terminal so that the positive connection terminal 40 is connected to the positive connection portion; one limiting member 30 restricts the installation posture of the negative connection terminal so that the negative connection terminal 40 is connected to the negative connection portion.

[0065] According to the battery device 101 of the present application, a first positioning portion is provided on the limiting member 30, and a second positioning portion is provided on the connection terminal 40. Through the cooperation of the first positioning portion and the second positioning portion, the connection terminal 40 is allowed to extend into the installation space 34, realizing the anti-fooling function during the assembly of the connection terminal 40.

[0066] In some embodiments, referring to Figures 4 - 9 , the first positioning portion includes a positioning protrusion 32 provided on the limiting member 30, and the second positioning portion includes a recessed area 43 provided on the connection terminal 40. The recessed area 43 is used to avoid the positioning protrusion 32 to allow the connection terminal 40 to extend into the installation space 34.

[0067] Exemplarily, the positioning protrusion 32 can be integrally formed on the limiting member 30, which can make the overall structure of the limiting member 30 more stable and reduce the risk of damage caused by loosening or breaking at the connection.

[0068] The first positioning portion includes a positioning protrusion 32. The setting method of the positioning protrusion 32 is simple, which also makes the processing method of the limiting member 30 simple; the second positioning portion includes a recessed area 43. The setting method of the recessed area 43 is simple, which also makes the processing method of the connection terminal 40 simple.

[0069] When the connection terminal 40 extends into the installation space 34 in a fixed installation posture, the recessed area 43 is used to avoid the positioning protrusion 32, allowing the connection terminal 40 to extend into the installation space 34. If the connection terminal 40 extends into the installation space 34 in other postures, the recessed area 43 cannot avoid the positioning protrusion 32, and the positioning protrusion 32 will block the connection terminal 40 from extending into the installation space 34 in other postures. Therefore, the connection terminal 40 can only move towards the installation space 34 in a fixed installation posture, realizing the anti-misassembly function during the assembly of the connection terminal 40.

[0070] In this embodiment, by setting the first positioning portion to include the positioning protrusion 32 and the second positioning portion to include the recessed area 43, the setting methods of the positioning protrusion 32 and the recessed area 43 are simple, and thus the processing methods of the limiting member 30 and the connection terminal 40 are simple.

[0071] In some embodiments, referring to Figures 3 - 5 、 Figure 8 , the positioning protrusion 32 is an annular plate-like structure.

[0072] Exemplarily, the positioning protrusion 32 is an annular plate-like structure, that is, the positioning protrusion 32 surrounds the limiting member 30. When the limiting member 30 is installed on the panel 20, the position of the positioning protrusion 32 does not need to be considered. No matter how the installation position of the limiting member 30 is adjusted, the function of the positioning protrusion 32 can be satisfied; moreover, since the positioning protrusion 32 is an annular plate-like structure, the weight of the limiting member 30 can be reduced, thereby reducing the cost of the limiting member 30.

[0073] In this embodiment, by setting the positioning protrusion 32 as an annular plate-like structure, when the limiting member 30 is installed on the panel 20, the positioning protrusion 32 can play a role in cooperating with the recessed area 43, and the weight of the limiting member 30 can also be reduced, thereby reducing the cost of the limiting member 30.

[0074] In some embodiments, referring to Figures 3 - 7 、 Figure 9 , the connection terminal 40 includes a first connection end 41 and a second connection end 42 connected along a first direction (refer to the X direction in Figure 4 ). The first connection end 41 is located at the end of the second connection end 42 away from the connection line for connecting to the connection portion 21. In a second direction (refer to Figure 5In the Y direction (as shown in the figure), the thickness of the second connection end 42 is greater than that of the first connection end 41, and the first connection end 41 is disposed on the side close to the second connection end 42, so as to construct a recessed area 43 between the first connection end 41 and the second connection end 42 on the other side close to the second connection end 42, wherein the first direction is perpendicular to the second direction.

[0075] Exemplarily, the connection terminal 40 includes a connected first connection end 41 and a second connection end 42. The first connection end 41 is connected to the connection portion 21, the second connection end 42 is connected to the connection wire, and the thickness of the second connection end 42 is greater than that of the first connection end 41. The first connection end 41 is disposed on the side close to the second connection end 42, and the recessed area 43 is located between the first connection end 41 and the second connection end 42 and on the other side of the second connection end 42.

[0076] If a concave area is also formed on one side in the second direction between the first connection end 41 and the second connection end 42, the concave area is disposed opposite to the recessed area 43 in the second direction, and the recessed area 43 is located between the first connection end 41 and the second connection end 42 and on the other side of the second connection end 42, such that the depth of the recess of the recessed area 43 in the second direction is greater than the depth of the recess of the concave area in the second direction.

[0077] If the connection terminal 40 extends into the installation space 34 in other postures, the concave area cannot avoid the positioning protrusion 32, and the positioning protrusion 32 will block the connection terminal 40 from extending into the installation space 34 in other postures. Furthermore, the connection terminal 40 can only move towards the installation space 34 in a fixed installation posture, realizing the anti-misassembly function during the assembly of the connection terminal 40.

[0078] For example, in the second direction, the cross-section of the first connection end 41 is rectangular, which is convenient for the first connection end 41 to be connected to the connection portion 21; the cross-section of the second connection end 42 is circular, which is convenient for the second connection end 42 to be connected to the connection wire.

[0079] In this embodiment, by setting the thickness of the second connection end 42 to be greater than that of the first connection end 41, and the first connection end 41 is disposed on the side close to the second connection end 42, and the recessed area 43 is located between the first connection end 41 and the second connection end 42 and on the other side of the second connection end 42, only the recessed area 43 can avoid the positioning protrusion 32. Furthermore, the connection terminal 40 can only move towards the installation space 34 in a fixed installation posture, realizing the anti-misassembly function during the assembly of the connection terminal 40.

[0080] In some embodiments, referring to Figures 3 - 5 、 Figure 9 , the direction of the first connection end 41 towards the connection portion 21 is the second direction. In the second direction, the side surface of the first connection end 41 towards the connection portion 21 is coplanar with the side surface of the second connection end 42 towards the connection portion 21.

[0081] The side of the first connection end 41 facing the connection portion 21 and the side of the second connection end 42 facing the connection portion 21 are coplanar. A recessed area 43 is machined on one side of the connection terminal 40 facing the second direction. Only one side of the connection terminal 40 facing the second direction is machined, making the machining method of the connection terminal 40 simple.

[0082] When the connection terminal 40 extends into the installation space 34 in other postures, the positioning protrusion 32 will block the connection terminal 40 from extending into the installation space 34 in other postures. As a result, the connection terminal 40 can only move into the installation space 34 in a fixed installation posture, realizing the anti-misassembly function during the assembly of the connection terminal 40.

[0083] In this embodiment, by setting the side of the first connection end 41 facing the connection portion 21 and the side of the second connection end 42 facing the connection portion 21 to be coplanar, only one side of the connection terminal 40 facing the second direction can be machined, making the machining method of the connection terminal 40 simple; moreover, the connection terminal 40 can only move into the installation space 34 in a fixed installation posture, realizing the anti-misassembly function during the assembly of the connection terminal 40.

[0084] In some embodiments, referring to Figure 9 , there is an arc transition between the first connection end 41 and the second connection end 42.

[0085] In this embodiment, by setting an arc transition between the first connection end 41 and the second connection end 42, stress concentration between the first connection end 41 and the second connection end 42 can be avoided, and the structural strength of the connection terminal 40 can be increased.

[0086] In some embodiments, referring to Figures 3 - 5 , Figure 8 , the electrical component 10 further includes: a wiring housing 50, the wiring housing 50 is connected to the panel 20, an installation cavity 51 is formed in the wiring housing 50, the installation cavity 51 has a first opening and a second opening oppositely arranged along the second direction, and a third opening 52 arranged on one side facing the first direction. The limiting member 30 is detachably installed at the first opening, the first positioning portion extends into the installation cavity 51, the connection portion 21 is located at a position opposite to the second opening, and the connection terminal 40 extends into the installation cavity 51 through the third opening 52.

[0087] Exemplarily, the connection terminal 40 extends into the installation cavity 51 through the third opening 52, and the wiring housing 50 can protect the connection terminal 40; the connection portion 21 is arranged opposite to the second opening, and the connection terminal 40 extends into the installation cavity 51 through the third opening 52 to be connected to the connection portion 21, and the wiring housing 50 also protects the connection portion 21.

[0088] In a specific example, the limiting member 30 can be pre-installed at the first opening, and then the connection terminal 40 is inserted into the installation cavity 51 from the third opening 52.

[0107] Exemplarily, using a connecting member to connect the connection terminal 40 and the connection portion 21 can increase the connection strength between the connection terminal 40 and the connection portion 21. For example, the connecting member can be a bolt.

[0108] In a specific example, the limiting member 30 can be pre-installed at the panel 20 first, and then the connection terminal 40 is installed into the installation space 34. After determining the installation posture of the connection terminal 40, the limiting member 30 is removed, and then a connecting member is passed through the first connection hole 22 and the second connection hole 411 to connect the connection terminal 40 and the connection portion 21.
