Description

Technical Field

[0001] The utility model relates to the technical field of batteries, in particular to a plugging component, a high-voltage socket with the same and a battery pack. Background Art

[0002] When an electric vehicle is running normally, the power system is in a high-voltage state. A high-voltage interlock circuit needs to be set to detect the connection condition between the battery pack and external high-voltage components. The battery pack is usually provided with a high-voltage socket that is plugged and connected with the plug of the external high-voltage component. When the high-voltage socket and the plug are in a stable plugged connection state, the high-voltage interlock circuit forms a conducting low-voltage loop, so that the electronic control system can detect the current of the high-voltage interlock circuit, and then judge that the high-voltage socket and the plug are stably plugged, and the power system forms a complete high-voltage loop, so that the vehicle can be used stably and reliably. When the high-voltage socket and the plug are loose or disconnected, the high-voltage interlock circuit is disconnected, so that the electronic control system can judge that a fault occurs in the high-voltage loop, so that the vehicle can adjust the driving state in time or perform maintenance treatment in time before starting, so that the vehicle can run and be used reliably and safely.

[0003] In the related art, the high-voltage interlock circuit usually needs to be integrally processed and provided with plugging components on the high-voltage socket and the plug of the external high-voltage component respectively. The plugging components are connected to the low-voltage wire harness of the high-voltage interlock circuit. After the high-voltage socket and the plug are plugged, the plugging components can be plugged and connected following the plugging of the high-voltage socket and the plug, and separated following the detachment of the plug and the high-voltage socket, so that the high-voltage interlock circuit can detect the connection state between the high-voltage socket and the plug.

[0004] Since the plugging structures are respectively arranged on the high-voltage socket and the plug and integrally processed with the high-voltage socket and the plug respectively, when the high-voltage socket is produced, a matching plug needs to be produced for use. The plug must be kept consistent with the port model of the high-voltage socket to make the plugging components cooperate stably and reliably, so that the high-voltage socket has high production process requirements during production and processing, and the production cost of the high-voltage socket is relatively high.

[0034] The embodiments of the present utility model will be described in detail below. The examples of the embodiments are shown in the drawings, wherein the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions from beginning to end. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present utility model and should not be construed as a limitation to the present utility model.

[0035] First, refer to Figures 1-5 A brief description is given to the battery pack according to the embodiment of the third aspect of the present utility model. The battery pack includes a housing and a high-voltage socket. The high-voltage socket can be used to cooperate with the plug of an external high-voltage component for plugging and connecting, and the plug can be plugged into the high-voltage socket along the first direction.

[0036] Next, refer to Figures 1-5 Describe the plug-in assembly 100 according to the embodiment of the first aspect of the present utility model.

[0037] As Figure 2 and Figure 3 shown, the plug-in assembly 100 according to the embodiment of the first aspect of the present utility model includes: a first plug-in member 10, a second plug-in member, and an elastic member. The first plug-in member 10 is provided with a first contact 14 and a second contact 15 of the high-voltage interlock circuit; the second plug-in member 20 is plugged and cooperated with the first plug-in member 10 along the first direction (such as the up and down direction shown in Figure 2 ), the second plug-in member 20 is provided with a conductive member 24, and the conductive member 24 is configured to cooperate with the first contact 14 and the second contact 15 to conduct the high-voltage interlock circuit; the elastic member is elastically deformable along the first direction, and both ends are respectively connected to the first plug-in member 10 and the second plug-in member 20. The second plug-in member 20 is configured to compress the elastic member after the high-voltage socket and the plug are plugged and fixed, so as to conduct the high-voltage interlock circuit.

[0038] In this embodiment, the plug-in component 100 includes a first plug-in member 10 and a second plug-in member 20. The first plug-in member 10 is plug-fitted with the second plug-in member 20 along a first direction, and an elastic member is connected between the first plug-in member 10 and the second plug-in member 20. When the plug is plugged into the high-voltage socket, the plug can apply a pressing force to the plug-in component 100 along the first direction, and the elastic member can be compressed under the clamping action of the plug and the high-voltage socket, so that the plugging degree of the first plug-in member 10 and the second plug-in member 20 along the first direction can be further increased. After the plug is plugged into the high-voltage socket in place, the first contact 14 and the second contact 15 in the first plug-in member 10 can contact and conduct with the conductive member 24 of the second plug-in member 20, so that the high-voltage interlock circuit is conducted, and the electric control system can detect the current or the formed pulse width modulation signal of the high-voltage interlock circuit, and then can judge that the high-voltage socket and the plug are stably connected.

[0039] After the plug is plugged into the high-voltage socket in place, the pressure formed by the cooperation between the plug and the high-voltage socket can suppress the elastic force of the elastic member, so that the relative positions of the first plug-in member 10 and the second plug-in member 20 along the first direction are kept stable, so that the high-voltage interlock circuit can maintain a stable conduction state when the plug and the high-voltage socket are stably plugged. When the plug and the high-voltage socket are loose or detached, the pressure on the elastic member formed by the cooperation between the plug and the high-voltage socket is reduced, so that the elastic member drives the first plug-in member 10 and the second plug-in member 20 to move away from each other along the first direction, and then the conductive member 24 is disconnected from the first contact 14 and the second contact 15, and the circuit of the high-voltage interlock circuit is disconnected. At this time, the electric control system can judge that there are problems such as loose connection or plug detachment between the high-voltage socket and the plug according to the change of the current or the pulse width modulation signal in the high-voltage interlock circuit, so that the electric control system can timely control the operating conditions of each high-voltage component in the power system to keep the vehicle in a stable, reliable and safe operating and using state. For example, it can timely give a warning for disconnecting the high-voltage circuit, so that the vehicle can have more time to take effective measures.

[0040] It can be understood that the high-voltage interlock circuit needs to form a connected loop. In this embodiment, the first plug-in member 10 is provided with a first contact 14 and a second contact 15 to cooperate with the conductive member 24, which is convenient for connecting and assembling with the low-voltage wire harness of the high-voltage interlock circuit, so that a loop can be formed between the first contact 14 and the second contact 15 through the conductive member 24, thus meeting the use requirements of the plug-in component 100.

[0041] In this embodiment, the second plug-in member 20 presses the elastic member after the high-voltage socket and the plug are plugged and fixed. Here, the pressing of the elastic member means that after the plug and the high-voltage socket are plugged in place, the second plug-in member 20 can make the elastic member in a certain degree of compression state under the pressure formed between the high-voltage socket and the plug. Specifically, the first plug-in member 10 and the second plug-in member 20 in this embodiment can be arranged between the surface of the high-voltage socket facing the plug and the plug. When the plug and the high-voltage socket are plugged, the plug can cooperate with the high-voltage socket to apply pressure to the plugging assembly 100, so as to meet the use requirements of the plugging assembly 100.

[0042] In this embodiment, the plugging assembly 100 connects the first plug-in member 10 and the second plug-in member 20 by setting an elastic member, and can separate the first plug-in member 10 and the second plug-in member 20 at the same time when the high-voltage socket and the plug are loose or separated, so that the high-voltage interlock circuit can be turned on and off in cooperation with the on and off of the high-voltage circuit, so that the plugging assembly 100 can well meet the detection requirements of the high-voltage interlock circuit for the high-voltage circuit.

[0043] In this embodiment, the first plug-in member 10 and the second plug-in member 20 of the plugging assembly 100 are connected by an elastic member to form a unified whole. The first contact 14 and the second contact 15 in the first plug-in member 10 can cooperate to conduct the high-voltage interlock circuit under the pressure when the plug and the high-voltage socket are plugged, and keep conducting or disconnecting the high-voltage interlock circuit following the change of the plugging state of the plug and the high-voltage socket through the elastic member, which can well meet the requirements of high-voltage interlock detection.

[0044] The plugging assembly 100 in this embodiment can well meet the requirements of high-voltage interlock detection through the plugging cooperation of the first plug-in member 10 and the second plug-in member 20 and the setting of the elastic member, so that the plugging assembly 100 can be arranged on the high-voltage socket to meet the use requirements, thus avoiding the relatively high production process requirements caused by the separate processing of the high-voltage socket and the plug, and avoiding the need to manufacture a matching plug when the high-voltage socket is produced and processed. As a result, the production cost of the high-voltage socket and the plug is lower, the high-voltage socket can be easily plugged with various types of plugs, making the applicability of the high-voltage socket wider. When the plugging assembly 100 is damaged or fails and needs to be replaced, only the high-voltage socket can be replaced, thus reducing the cost of replacing the plugging assembly 100 of the battery pack to a certain extent.

[0045] According to the plug-in assembly 100 of the embodiments of the present utility model, by providing a first plug-in member 10 and a second plug-in member 20, the first plug-in member 10 and the second plug-in member 20 are plugged and matched along a first direction, and both ends of the elastic member along the first direction are respectively connected to the first plug-in member 10 and the second plug-in member 20, which can well meet the need for high-voltage interlock detection between a high-voltage socket and a plug. The structure is simple and can be integrally arranged on the high-voltage socket, reducing the production process requirements of the high-voltage socket and avoiding the production of matching plugs, thereby making the production cost of the high-voltage socket lower and the applicability wider, and reducing the replacement cost when the battery pack replaces the plug-in assembly 100.

[0047] In this embodiment, the first plug-in member 10 is provided with the first main body 11, the second plug-in member 20 is provided with the second main body 21 and the second main body 21 is provided with the slot 201, and the opening of the slot 201 faces the first main body 11. After the plug-in assembly 100 is assembled, the second main body 21 is plugged and connected to the first main body 11, so that the second main body 21 and the first main body 11 can form a good connection structure strength, and the overall structure of the first plug-in member 10 and the second plug-in member 20 can be kept stable relatively well, and to a certain extent, the plug-in assembly 100 can be more convenient and easier to take and use.

[0048] In this embodiment, when the plug is plugged into the high-voltage socket, the first main body 11 can move relative to the second main body 21 along the first direction and continue to move into the slot 201 along with the movement of the plug, so that the conductive member 24 in the slot 201 can gradually move towards the first contact 14 and the second contact 15. Furthermore, when the plug is plugged into the high-voltage socket in place, the conductive member 24 can contact and conduct with the first contact 14 and the second contact 15, thereby making the high-voltage interlock circuit conduct.

[0049] In this embodiment, the second main body 21 is provided with the slot 201, which can well meet the need for the plug-in connection between the first plug-in member 10 and the second plug-in member 20 and the relative movement along the first direction, and can provide a good installation and arrangement position and a protective effect for the conductive member 24, so that the plug-in assembly 100 can operate stably and reliably after being assembled.

[0051] In this embodiment, the first body 11 is provided with a first channel 101 and a second channel 102, and the conductive member 24 is provided with a first rod body 241 and a second rod body 242. The first rod body 241 is inserted into the first channel 101 along the first direction, and the second rod body 242 is inserted into the second channel 102 along the first direction. The structure is simple. The cooperation between the first rod body 241 and the first channel 101 can play a role in guiding and plugging and fixing, and the cooperation between the second rod body 242 and the second channel 102 can play a role in guiding and plugging and fixing, so that the first plug-in member 10 and the second plug-in member 20 can be plugged and connected and relatively moved along the first direction more stably and reliably.

[0052] In this embodiment, one end of the first channel 101 facing away from the second plug-in member 20 is provided with a first contact 14, and one end of the second channel 102 facing away from the second plug-in member 20 is provided with a second contact 15.

[0060] When the plug is plugged into the high-voltage socket, the second plug-in member 20 is further inserted into the first plug-in member 10 along the first direction relative to the first plug-in member 10 under the pressure formed by the cooperation of the plug and the high-voltage socket. The second sleeve 22 follows the second main body 21 and further penetrates into the first sleeve 12, so as to cooperate with the first sleeve 12 to stably and reliably compress the elastic member against the elastic force of the elastic member. The inner wall of the receiving cavity can play a good limiting role on the elastic member, enabling the elastic member to elastically deform stably along the first direction, so that the elastic member can apply a separating force between the first plug-in member 10 and the second plug-in member 20 along the first direction. Thus, when the plug-in of the high-voltage socket and the plug becomes loose or the plug falls off, the elastic member can stably, effectively and timely drive the first plug-in member 10 and the second plug-in member 20 to separate, so that the high-voltage interlock detection operation of the plug-in assembly 100 runs more stably.

[0061] In this embodiment, the cooperation between the first sleeve 12 and the second sleeve 22 can further improve the stability and reliability of the plug-in connection between the first plug-in member 10 and the second plug-in member 20, enabling the first plug-in member 10 and the second plug-in member 20 to cooperate more stably and reliably.

[0062] In some examples of the present utility model, such as Figure 4 and Figure 5 as shown, the number of the first sleeves 12 can be multiple. The multiple first sleeves 12 are respectively arranged on both sides of the first body 11 in the third direction (such as the front-back direction shown in Figure 4 ). The number of the second sleeves 22 and the elastic members are both provided as multiple. The multiple second sleeves 22 and the multiple elastic members are arranged in one-to-one correspondence with the first sleeves 12. The third direction intersects with the first direction.

[0063] In this embodiment, arranging multiple first sleeves 12 in one-to-one correspondence with multiple second sleeves 22 and multiple elastic members can enable the multiple elastic members to cooperate more stably, reliably and timely to drive the first plug-in member 10 and the second plug-in member 20 to disengage, so that the conductive member 24 and the first contact 14 and the second contact 15 can disconnect the high-voltage interlock circuit in time when the plug and the high-voltage socket become loose or fall off, thereby performing the high-voltage interlock detection operation more stably and accurately, and enabling the plug-in assembly 100 to operate more stably and reliably.

[0064] It can be understood that the first plug-in member 10 and the second plug-in member 20 have a certain volume in space. When the first plug-in member 10 and the second plug-in member 20 are plug-connected and cooperate in the first direction, the first plug-in member 10 and the second plug-in member 20 extend in a certain range in other directions. In this embodiment, arranging multiple first sleeves 12 on both sides of the first body 11 in the third direction can enable the first plug-in member 10 and the second plug-in member 20 to obtain a relatively uniform elastic force of the elastic members within the extension range in the third direction, so that when the first plug-in member 10 and the second plug-in member move towards each other or away from each other in the first direction, the overall structure of the first plug-in member 10 and the second plug-in member can move more stably and reliably, so that the conductive member 24 can be more stably conducted with or disconnected from the first contact 14 and the second contact 15, and the plug-in assembly 100 can operate more stably and reliably.

[0065] For example, the number of the first sleeves 12 can be two, three, four, five, etc. The first sleeves 12 can be respectively arranged on both sides of the first body 11 in the third direction. The second sleeves 22 and the elastic members can be arranged in one-to-one correspondence with the first sleeves 12.

[0066] In some examples of the present utility model, such as Figure 3As shown, the first body 11 is provided with limiting ribs 13 on both sides of the second direction, and the second plug-in connector 20 may also include a clip 23, which is arranged on both sides of the second body 21 in the second direction, and the clip 23 is connected to the second body 21 at one end away from the first body 11 along the first direction, and a card groove 231 is formed on the side of the clip 23 facing the second body 21 in the second direction, and the first body 11 and the second body 21 are connected by the limiting rib 13 and the card groove 231.

[0067] In this embodiment, a clamping member 23 is provided on both sides of the second main body 21 in the second direction, and the clamping member 23 is provided with a clamping groove 231. The first main body 11 is provided with limiting ribs 13 on both sides of the second direction. The first main body 11 and the second main body 21 are clamped and connected through the limiting ribs 13 and the clamping groove 231. This can prevent the first connector 10 and the second connector 20 from being completely separated under the force generated by the elastic deformation of the elastic member when the plug is too loose or falls off from the high-voltage socket, so that the first connector 10 and the second connector 20 can stably and reliably maintain a good connection structure, so that the overall structure of the plug assembly 100 can be more stable and reliable during use.

[0068] In this embodiment, the card slot 231 is formed on the side of the card connector 23 facing the second body 21. Specifically, the second body 21 can be formed with avoidance grooves on both sides of the second direction. The opening of the avoidance groove faces the first body 11 and penetrates the second body 21 along the second direction to communicate with the slot 201. When the first connector 10 and the second connector 20 are assembled, as the first body 11 extends into the slot 201, the limiting ribs 13 on both sides of the first body 11 can pass through the avoidance groove to abut against the external card connector 23 and gradually slide into the card slot 231. The limiting ribs 13 can abut against the side wall of the card slot 231 in the first direction close to the opening of the avoidance groove, so that the limiting ribs 13 and the card slot 231 are clamped and fixed to resist the elastic force of the elastic member, so that the first connector 10 and the second connector 20 can form a stable connection position relationship and connection structure state.

[0069] In this embodiment, the end of the clamping member 23 away from the first main body 11 along the first direction is connected to the second main body 21. Specifically, the clamping member 23 and the second main body 21 can have a certain gap in the second direction to facilitate the movement of the limiting rib 13. The end of the clamping member 23 away from the first main body 11 is connected to the second main body 21, which can facilitate the connection and fixation of the clamping member 23, avoid the connection part between the clamping member 23 and the first main body 11 hindering the movement of the limiting rib 13, and enable the clamping member 23 to cooperate well with the limiting rib 13 to perform the clamping operation.

[0070] In an embodiment of the present utility model, the card slot 231 can extend along the first direction, and there can be a gap between the side wall surface of the card slot 231 facing away from the limiting rib 13 and the limiting rib 13. In this way, when the plug is inserted into the high-voltage socket, the limiting rib 13 can move in the card slot 231 along the first direction, so as to meet the need for relative movement between the first plug-in member 10 and the second plug-in member 20.

[0073] In this embodiment, the plug-in assembly 100 is snap-connected to the socket body, with a simple structure, convenient fixation, and easy assembly. The plug-in assembly 100 can be processed and manufactured separately, so that when the plug-in assembly 100 needs to be replaced, it can be replaced separately, which well avoids the problem of high replacement cost caused by the overall replacement of the socket body and the plug-in assembly 100, and makes the replacement cost of the battery pack lower when replacing the plug-in assembly 100. In this embodiment, the plug-in assembly 100 is snap-connected to the socket body. Specifically, the first plug-in member 10 of the plug-in assembly 100 can be snap-connected to the socket body, and the plug-in assembly 100 can be arranged on one side surface of the socket body for plugging and mating with the plug to meet the use requirements of the plug-in assembly 100.
