[0073] For traditional CTP (Cell to Pack) battery packs, the high-voltage connector is typically a single, integrated unit. The high-voltage connector is directly integrated into the battery pack at the battery factory, and the interface is sealed. The battery pack is then secured to the vehicle frame at the assembly stage via external connection points. However, for CTC (Cell to Chassis) battery packs, the cells and distribution box are directly integrated into the vehicle chassis. One end of the integrated high-voltage connector needs to connect to the distribution box, while the other end needs to penetrate the vehicle frame for connection to the Battery Management System (BMS) or other structures. This makes the traditional high-voltage connector installation method for CTP battery packs unsuitable for CTC battery packs.

[0074] In related technologies, to facilitate the electrical connection between high-voltage connectors and distribution boxes, high-voltage connectors are typically made in a split configuration. One portion of the connector is installed together with the distribution box, and then the entire assembly is installed into the receiving cavity formed by the vehicle chassis. However, the installation of the assembly formed by one portion of the connector and the distribution box onto the vehicle chassis still suffers from difficulties in assembly and low positioning accuracy, hindering rapid and efficient assembly and reducing the assembly efficiency of the high-voltage connectors.

[0075] To address the aforementioned technical problems, embodiments of this application provide an installation structure, a plug-in assembly, a battery system, a vehicle, and an energy storage device. By providing a guide with a guide groove on the mounting body, when installing the first plug-in, the first plug-in can be controlled to move in the direction toward the second mounting surface, so that the first plug-in moves into the guide groove through the second opening. In this way, the guide groove can provide a precise track for the movement of the first plug-in, improving the installation efficiency of the first plug-in while reducing installation errors caused by the uncertainty of manual operation.

[0076] In addition, the first connector is directly engaged in the guide groove, which can also improve the connection strength between the first connector and the mounting body.

[0077] To make the above-mentioned objectives, features, and advantages of the embodiments of this application more apparent and understandable, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0078] This application provides an installation structure 100, which can be a standalone component or a part of a vehicle or energy storage device. In some embodiments, when the vehicle's battery pack eliminates the need for a separate housing and integrates the battery directly onto the vehicle frame, the installation structure 100 can be part of the vehicle frame.

[0079] The mounting structure 100 is used to mount the connector 200 (please refer to...). Figures 8 to 11 That is, the mounting structure 100 serves as the mounting carrier for the connector 200. The connector 200, mounted on the mounting structure 100, can be used to connect to the distribution box 20 (see reference). Figures 8 to 11 ).

[0080] Please refer to Figure 13 and Figure 14 The connector 200 includes a first connector 210 and a second connector 220. The first connector 210 and the second connector 220 are detachably connected, for example, the first connector 210 and the second connector 220 are connected by a plug-in method.

[0081] Please refer to Figures 1 to 5The mounting structure 100 provided in this application embodiment includes a mounting body 110, which may be a part of a vehicle frame. The mounting body 110 includes a first mounting surface 111 and a second mounting surface 112. The first mounting surface 111 and the second mounting surface 112 are adjacent to each other, and the first mounting surface 111 intersects the second mounting surface 112. In some embodiments, the mounting body 110 may include a top plate and a side plate, which together form a cavity for accommodating a battery. The first mounting surface 111 may be the inner surface of the side plate, and the second mounting surface 112 may be the inner surface of the top plate.

[0082] The mounting structure 100 also includes a guide 120, which is disposed on the first mounting surface 111. For example, the guide 120 may be welded or otherwise fixedly connected to the first mounting surface 111.

[0083] Please refer to Figure 2 and Figure 5 The mounting structure 100 also includes an opening disposed on the guide member 120. The opening includes a first opening 1211 and a second opening 1212 that are interconnected. Both the first opening 1211 and the second opening 1212 communicate with the inner cavity of the guide groove 121. Alternatively, the first opening 1211 and the second opening 1212 are interconnected and together form a communication structure with the guide groove 121.

[0084] The first opening 1211 is disposed opposite to the first mounting surface 111, that is, the guide groove 121 penetrates the surface of the guide member 120 opposite to the first mounting surface 111 along a first direction, wherein the first direction is perpendicular to the first mounting surface 111. Figure 3 and Figure 5 In the X direction.

[0085] The second opening 1212 is located on one side of the first opening 1211 and is opposite to the second mounting surface 112. That is, the second opening 1212 is the bottom opening of the guide member 120. Specifically, the guide groove 121 penetrates the surface of the guide member 120 opposite to the second mounting surface 112 along a second direction. The second direction intersects the first direction; for example, the second direction and the first direction are perpendicular to each other. The second direction is... Figure 3 and Figure 5 In the Z-direction.

[0086] The first connector 210 moves through the second opening 1212 into the guide groove 121 and is engaged within it. Thus, as the first connector 210 moves along the second direction toward the mounting structure 100, it can move into the guide groove 121 with the aid of the guide member 120. In this way, the guide groove 121 provides a precise track for the movement of the first connector 210, improving the installation efficiency of the first connector 210 while reducing installation errors caused by the uncertainty of manual operation.

[0087] In addition, the first connector 210 is directly engaged in the guide groove 121, which can also improve the connection strength between the first connector 210 and the mounting body 110.

[0088] In some embodiments, the width of the guide groove 121 in the first direction tends to decrease in the second direction and in the direction pointing to the second mounting surface 112; the first direction is perpendicular to the first mounting surface 111, and the second direction is perpendicular to the second mounting surface 112.

[0089] In other words, with Figure 5 Taking the orientation shown as an example, the width of the guide groove 121 decreases from bottom to top. During the process of the first connector 210 being inserted into the guide groove 121 through the second opening 1212, the sidewall of the guide groove 121 exerts a gradually increasing squeezing force on the first connector 210, forming an effective clamping effect. This clamping force not only further enhances the connection strength between the first connector 210 and the mounting body 110, but also effectively resists the influence of adverse factors such as external vibration and impact, ensuring that the connection part can remain stable under complex working conditions, thereby improving the reliability and service life of the entire mounting structure 100 and connector 200.

[0090] It should be understood that the width of the guide groove 121 decreases in the first direction, which can be interpreted as the width of the guide groove 121 gradually decreasing in the first direction. Alternatively, it can be understood that the width of the guide groove 121 in the first direction only needs to be less than the width of its top, and does not need to be limited to a gradual decrease.

[0091] Please continue to refer to this. Figure 5The guide groove 121 includes a guide wall 1213 disposed opposite to the first mounting surface 111, and the guide wall 1213 is inclined in a direction away from the first mounting surface 111. Alternatively, the guide wall 1213 is inclined relative to a second direction and extends in a direction away from the first mounting surface 111. This further increases the width of the second opening 1212 of the guide groove 121 in the first direction. The wider second opening 1212 provides more operating space for the insertion of the first connector 210, which improves installation efficiency and reduces installation time. Furthermore, when the first connector 210 enters the guide groove 121 through the second opening 1212, the inclined guide wall 1213 can guide the first connector 210 along a preferred path into the guide groove 121, effectively avoiding problems such as jamming and collision during insertion, and improving the accuracy and reliability of installation.

[0092] In one possible implementation, the second opening 1212 also penetrates the guide 120 along a third direction, wherein the third direction, the second direction, and the first direction intersect each other. The third direction can... Figure 2 Center Y direction.

[0093] In this way, the guide groove 121 forms a structure with three openings. When the first plug 210 enters the guide groove 121 through the second opening 1212, the first plug 210 can pass through the guide groove 121 along the third direction, and can freely change the position of the first plug 210 in the guide groove 121. It can also increase the contact area between the first plug 210 and the guide 120, thereby increasing the pressing force between the two and improving the connection stability of the two.

[0094] Please continue to refer to this. Figure 2 The guide member 120 provided in this application embodiment includes a first guide plate 122 and two second guide plates 123. The first guide plate 122 is connected to the first mounting surface 111. For example, the first guide plate 122 can be welded to the first mounting surface 111 of the mounting body 110.

[0095] Two second guide plates 123 are disposed on the side of the first guide plate 122 opposite to the first mounting surface 111 and are arranged at intervals. For example, the two second guide plates 123 are spaced apart along a third direction. In this way, the first guide plate 122 and the two second guide plates 123 enclose a guide groove 121. The two second guide plates 123 and the first guide plate 122 can be separate structures or integral parts. Exemplarily, the two second guide plates 123 and the first guide plate 122 are integrally formed, which can improve the structural strength of the guide member 120.

[0096] by Figure 5Taking the orientation shown as an example, the longitudinal cross-sectional shape of the guide member 120 is similar to an inverted L-shape. In this way, the area between the two second guide plates 123 forms the first opening 1211 of the guide groove 121, and the area between the two second guide plates 123 and the first mounting surface 111 forms the second opening 1212 of the guide groove 121.

[0097] When the guide member 120 includes two second guide plates 123, each second guide plate 123 is inclined in a direction away from the first mounting surface 111, so that the guide member 120 has two inclined guide walls 1213, which better guides the first plug-in 210 into the guide groove 121 along the preferred path, effectively avoiding problems such as jamming and collision of the first plug-in 210 during the insertion process, and improving the accuracy and reliability of installation.

[0098] It should be noted that when the guide member 120 includes the second guide plate 123, the inner surface of the second guide plate 123 facing the first mounting surface 111 can be entirely inclined relative to the second direction, so that the entire inner surface of the second guide plate 123 constitutes the guide wall 1213. Alternatively, a portion of the inner surface of the second guide plate 123 may constitute the guide wall 1213.

[0099] In some embodiments, please refer to Figure 5 Each second guide plate 123 includes a first guide portion and a second guide portion that are connected to each other, and the first guide portion is connected to the first guide plate 122.

[0100] The tilt angle of the second guide portion relative to the plane where the first mounting surface 111 is located is greater than the tilt angle of the first guide portion relative to the plane where the first mounting surface 111 is located. For example, the tilt angle of the first guide portion relative to the second direction can also be zero.

[0101] When the first connector 210 enters the guide groove 121 along the second guide portion with a larger tilt angle, the larger tilt angle can provide a stronger guiding force, quickly and accurately guiding the first connector 210 to the predetermined position, reducing the adjustment time of the first connector 210 in the guide groove 121, and greatly improving the installation efficiency.

[0102] In addition, the smaller tilt angle of the first guide portion can increase the contact area between the first guide portion and the first connector 210, thereby increasing the connection strength between the first connector 210 and the mounting body 110.

[0103] In one possible implementation, please refer to Figure 3 and Figure 4The mounting body 110 is provided with a mounting hole 113, which is located on the first mounting surface 111 and communicates with the guide groove 121, extending through the mounting body 110 in the first direction. The mounting hole 113 is used to accommodate the connection portion of the first connector 210 and the second connector 220.

[0104] It should be noted that the diameter of the mounting hole 113 can be the same everywhere or different. For example, the mounting hole 113 includes a first mounting hole 1131 and a second mounting hole 1132 that are interconnected, and the diameter of the first mounting hole 1131 is smaller than the diameter of the second mounting hole 1132.

[0105] Thus, along the first direction, the first mounting hole 1131 and the second mounting hole 1132 form two stepped surfaces, one of which faces the guide groove 121 and the other of which faces away from the guide groove 121.

[0106] The first mounting hole 1131 is used to accommodate a portion of the first connector 210. Thus, the stepped surface facing the guide groove 121 provides support for the first connector 210, effectively increasing the contact area and support points between the first connector 210 and the mounting body 110. This allows the first connector 210 to experience a more uniform and stable constraint force within the mounting body 110, thereby significantly improving the connection strength between the first connector and the mounting body. The second mounting hole 1132 is used to accommodate a portion of the second connector 220. Thus, the stepped surface facing away from the guide groove 121 provides support for the second connector 220, further improving the connection strength between the second connector 220 and the mounting body 110.

[0107] This application also provides a plug-in component 10, please refer to... Figures 6 to 9 The plug-in assembly 10 includes a plug-in member 200 and the mounting structure 100 described in any of the above embodiments. The plug-in member 200 includes a first plug-in member 210 and a second plug-in member 220.

[0108] Please refer to Figure 10 , Figure 11 and Figure 12 The first connector 210 is partially engaged in the guide groove 121 of the mounting structure 100 and exposed within the mounting hole 113 of the mounting structure 100. The second connector 220 is partially located within the mounting hole 113 of the mounting structure 100 and is detachably connected to the first connector 210. The first connector 210 can be plugged into the second connector 220.

[0109] In practical use, the first connector 210 is first moved along the second direction, so that it moves along the guide groove 121 of the mounting structure 100, so that it can be engaged in the guide groove 121 while also being exposed in the mounting hole 113 of the mounting structure 100. Then, the second connector 220 is inserted into the mounting hole 113 and connected to the first connector 210. In this way, by making the connector 200 a separate component and having it cooperate with the guide 120 of the mounting structure 100, the assembly difficulty of the connector 200 is reduced.

[0110] Please refer to Figure 14 The first connector 210 is sealed to the mounting body 110 of the mounting structure 100 via a first sealing member 230. In some embodiments, the first sealing member 230 may be sleeved on the first connector 210, so that the first sealing member 230 can be sealed to the inner wall of the mounting hole 113. In other embodiments, the first sealing member 230 may also be disposed on the end face of the first connector 210 facing the first mounting surface 111, and a sealed connection is formed between the first sealing member 230 and the first mounting surface 111.

[0111] To enhance the stability of the first seal 230, a sealing groove (not shown in the figure) is provided on the end face of the first connector 210 facing the mounting body 110, and the first seal 230 is housed within the sealing groove. In this way, the sealing groove provides a dedicated space for the first seal 230, greatly reducing the risk of the first seal 230 falling off due to force, thereby ensuring that the sealing performance between the first connector 210 and the mounting body 110 remains stable and reliable.

[0112] Please continue to refer to this. Figure 14 The first connector 210 includes a guide portion 211, which cooperates with the guide wall 1213 of the mounting structure 100 to achieve precise insertion of the first connector 210 and the guide groove 121 of the mounting body 110.

[0113] In one possible implementation of the guide portion 211, the guide portion 211 is a guide ramp. This guide ramp is inclined relative to the plane containing the first mounting surface 111 and extends toward the mounting body 110. During the insertion of the first connector into the mounting body, the guide ramp gradually contacts the guide wall of the mounting structure. As the insertion deepens, the guide ramp slides along the guide wall, guiding the first connector 210 to move accurately along a predetermined path, thereby achieving precise insertion.

[0114] In another possible implementation of the guide portion 211, the guide portion 211 is a guide groove. The guide groove is also inclined relative to the plane containing the first mounting surface 111 and extends towards the mounting body 110. The second guide plate 123 of the mounting structure 100 slides in the guide groove. When the first connector 210 is inserted, the guide groove slides along the second guide plate 123. The inclined arrangement of the guide groove allows the first connector to receive more precise guidance during insertion, effectively reducing shaking and deviation during insertion, and enabling the first connector 210 to reach the installation position more accurately.

[0115] In one possible implementation, the second connector 220 is sealed to the mounting body 110 of the mounting structure 100 via the second seal 240, ensuring good sealing at the connection between the two and preventing the intrusion of external substances.

[0116] The relative positions of the second seal 240 and the second connector 220 can be selected in various ways. In some embodiments, please refer to... Figure 7 , Figure 8 and Figure 9 The second connector 220 includes a connector section located within the mounting hole, and a second seal 240 surrounding the connector section and sealingly connected to the inner wall of the mounting hole 131. When the second connector is inserted into the mounting hole, the second seal is pressed between the connector section and the inner wall of the mounting hole, forming a reliable sealing barrier to prevent external dust, moisture, etc., from entering the mounting hole. Simultaneously, during insertion, it can quickly seal and connect with the mounting body 110, and also enables rapid assembly between the first connector 210 and the second connector 220.

[0117] And / or, please refer to Figure 15 and Figure 16 The second connector 220 also includes an outer section located outside the mounting hole; the end face of the outer section facing the mounting body 110 is sealed to the mounting body 110 through the second sealing member 240.

[0118] When both the outer section and the plug section of the second plug-in 220 are sealed to the mounting body 110 through the second seal 240, the sealing performance of the plug-in assembly 10 can be greatly improved.

[0119] This application also provides a battery system, including a power distribution box 20 and a plug-in assembly 10 as described in any of the above embodiments. The first plug-in member 210 of the plug-in assembly 10 is connected to the power distribution box 20 via a connecting strip 30, facilitating electrical connection between the power distribution box 20 and other structures.

[0120] Since the embodiments of this application include the plug-in component 10, they possess all the structure and all the beneficial effects of the plug-in component 10, and this embodiment will not be further limited here.

[0121] It should be noted that the connecting strip 30 can be connected to the first plug-in 210 by bolts to improve the connection strength between the connecting strip and the first plug-in 210.

[0122] Please refer to 12. The connecting strip 30 is at least partially made of an elastic material, and a portion of the connecting strip 30 protrudes along a direction perpendicular to the second mounting surface of the mounting structure 100 to form an elastic deformation portion 31. The shape of the elastic deformation portion 31 can be arc-shaped or wavy.

[0123] Thus, as the first connector 210 moves along the guide groove 121, it creates tensile stress on the connecting strip 30, stretching its length. In actual manufacturing and installation, it is difficult to guarantee perfect dimensional and positional accuracy between components. The elastic deformation portion 410 of the connecting strip 30 has a certain elastic deformation capacity, which can compensate for positional deviations between the first connector 210 and other components caused by manufacturing errors and installation deviations. For example, when there is a slight deviation in the connection position between the first connector 210 and the connecting strip 30, the elastic deformation portion 310 can automatically adjust the shape and position of the connecting strip 30 through elastic deformation, ensuring a good electrical and mechanical connection between the first connector 210 and the connecting strip 30, and improving the stability and reliability of the connection.

[0124] Please continue to refer to this. Figure 13 and Figure 14 The battery system also includes a carrier 40 and multiple battery cells 50. The multiple battery cells 50 and the distribution box 20 are both mounted on the carrier 40. For example, the multiple battery cells 50 are arranged in an array on the carrier 40 and located on one side of the distribution box 20.

[0125] The carrier 40 is also used to connect to the mounting body 110 of the plug-in assembly 10 and to form a closed chamber with the mounting body 110. The closed chamber is used to accommodate multiple battery cells 50 and the distribution box 20.

[0126] Please combine Figure 3 and Figure 13 First, multiple battery cells 50 and the distribution box 20 are installed on the carrier 40, and the first connector 210 is electrically connected to the distribution box 20 through the connecting strip 30.

[0127] After that, along Figure 3 The first connector 210 moves along the guide groove 121 of the guide member 120 in the second direction Z direction towards the mounting body 110 until the first connector 210 moves to the mounting hole 113 of the mounting body 110 and exposes the insertion section of the first connector 210.

[0128] Then, the second connector 220 is inserted into the mounting hole 113 and connected to the first connector 210.

[0129] During the movement of the first connector 210 along the guide groove 121 of the guide member 120, given that the width of the guide groove 121 tends to decrease, the elastic deformation portion of the connecting strip 30 can adaptively stretch with the change in the width of the guide groove 121, avoiding interference problems between the connecting strip 30 and the first connector 210 or the guide member 120 that may occur due to changes in the width of the guide groove 121. For example, in the region where the width of the guide groove 121 gradually narrows, without the adaptive adjustment of the elastic deformation portion, the connecting strip 30 may be squeezed or collided with the sidewall of the guide groove, hindering the normal movement of the first connector 210.

[0130] Meanwhile, given that a first sealing element 230 is provided on the end face of the first connector 210 facing the mounting body 110, the first sealing element 230 can also achieve automatic sealing between the first connector 210 and the mounting body 110 after the first connector 210 moves into place.

[0131] It should be noted that the carrier 40 and the mounting body 110 require conventional fixed connection and sealing. This embodiment will not elaborate further here.

[0132] This application also provides a vehicle, which includes a vehicle body frame and a battery system as described in any of the above embodiments, wherein the battery system mounting body can be a part of the vehicle body frame. This eliminates the need for a separate battery casing for the battery system, allowing it to be directly integrated into the vehicle body frame, reducing the overall weight of the vehicle and contributing to an increase in driving range.

[0133] Furthermore, in this embodiment, by configuring the connector 200 as a split structure, the connector 200 includes a first connector 210 and a second connector 220. In this way, the first connector 210 and the second connector 220 can be connected together without setting an opening on the carrier 40, thus realizing the rapid assembly of the connector 200.

[0134] This application also provides an energy storage device, including the battery system described in any of the above embodiments. Since the energy storage device provided in this application includes the battery system described in any of the above embodiments, it possesses all the structure and beneficial effects of a battery system, and will not be described in detail here.
