[0044] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0045] The battery module 1 of a vehicle according to an embodiment of the present invention is described below with reference to the accompanying drawings.

[0046] like Figures 1-6 As shown, the battery module 1 of the vehicle according to an embodiment of the present invention includes a tray 10, a battery section 20, a support member 30, and a power distribution assembly 40.

[0047] The vehicle frame 70 defines a housing 700 with an opening on at least one side. A tray 10 is fixed to the frame 70 to cover the opening of the housing 700. The tray 10 and the housing 700 cooperate to define a receiving cavity. The battery unit 20 is placed on the surface of the tray 10 and located in the receiving cavity, so as to protect the battery unit 20 by the shell formed by the housing 700 and the tray 10, and at the same time provide a relatively sealed working environment for the battery unit 20, so that the battery unit 20 can be charged and discharged stably.

[0048] It should be noted that the opening can be a top opening, a bottom opening, or a side opening of the housing 700; there are no strict limitations. When the tray 10 is installed onto the frame 70, the battery section 20 is adapted to extend into the receiving cavity through the opening.

[0049] The use of the frame 70 to form part of the housing of the battery section 20 makes it easier to eliminate redundant structures such as the housing of the battery module 1, simplify the production process, and reduce material costs. At the same time, after the battery module 1 is installed on the frame 70, the overall weight of the frame 70 and the battery module 1 can be reduced, thereby achieving vehicle lightweighting, improving energy efficiency, and indirectly increasing the vehicle's driving range.

[0050] Specifically, this application directly embeds the battery module 1 into the vehicle frame, which improves the utilization rate of the space in the vehicle chassis. This allows more battery cells to be accommodated in a limited space, which is conducive to increasing the capacity of the battery module 11.

[0051] The power distribution component 40 is mainly responsible for the distribution of electrical energy, circuit protection, and system safety management in the battery section 20. The support member 30 is fixed to the surface of the tray 10 and located on one side of the battery section 20. The power distribution component 40 is located on the tray 10. The power distribution component 40 includes a connector 41, which is installed on the support member 30 to support the connector 41. The housing 700 is provided with a clearance opening 711 for the exposed connector 41, so that external parts can be electrically connected to the connector 41 on the support member 30 through the clearance opening 711, thereby realizing the electrical connection between the power distribution component 40 and the external parts and realizing the power supply of the battery module 1 to the outside.

[0052] In other words, by setting a support member 30 on the tray 10, the position of the connector 41 is supported by the support member 30, so that the connector 41 is opposite to the clearance opening 711 on the housing 700, and external parts can be electrically connected to the connector 41 through the clearance opening 711.

[0053] Specifically, in some existing technologies, the battery pack housing is an independent structure, and the connector can be directly set on the battery pack housing during battery pack manufacturing. However, since this application is a CTC battery structure, the battery section 20 housing is defined by the frame 70. The frame 70 and the battery module 1 are manufactured independently. When manufacturing the battery module 1 separately, if the connector 41 is set on the tray 10, pollutants and other items on the ground can easily contaminate the connector 41 when the vehicle is in motion. There is also a certain risk when the vehicle is hit by stones or when it is in water. At the same time, it will occupy the vertical space of the chassis and affect the arrangement of other structures on the chassis.

[0054] Therefore, when manufacturing the battery module 1 independently, it is impossible to place the connector 41 on the tray 10. Therefore, this application provides a support member 30 on the tray 10 and a clearance opening 711 on the housing 700. The support member 30 is used to support the connector 41. In this way, after the battery module 1 is installed on the frame 70, external parts can be connected to the connector 41 on the support member 30 through the clearance opening 711, which solves the problem of the electrical connector 41 in the CTC battery structure.

[0055] Therefore, according to the embodiment of the present utility model, the battery module 1 of the vehicle is provided with a support member 30 on the tray 10, and the connector 41 is supported by the support member 30, so that the connector 41 can be electrically connected to external parts through the clearance opening 711 on the frame 70, thus solving the problem of the electrical connector 41 in the CTC battery structure.

[0056] The battery module 1 of a vehicle according to a specific embodiment of the present invention is described below with reference to the accompanying drawings.

[0057] In some specific embodiments of this utility model, such as Figures 1-6As shown, the vehicle's battery module 1 includes a tray 10, a battery section 20, a support member 30, and a power distribution assembly 40.

[0058] In some embodiments of this utility model, such as Figure 3 , Figure 4 As shown, the vehicle's battery module 1 also includes a sealing assembly 50. The sealing assembly 50 is disposed on and sealed with the support member 30. The sealing assembly 50 is arranged around the connector 41. The sealing assembly 50 is adapted to be located inside the clearance opening 711 to seal with the inner wall of the clearance opening 711, thereby sealing the gap between the inner wall of the clearance opening 711 and the support member 30. This prevents external impurities from entering the receiving cavity from the gap between the inner wall of the clearance opening 711 and the support member 30, thus fully protecting the components inside the receiving cavity and preventing external impurities from contaminating or damaging the battery section 20 and the power distribution assembly 40 inside the receiving cavity.

[0059] It should be explained here that the surface area of ​​the support member 30 facing the clearance opening 711 is larger than that of the clearance opening 711. At the same time, the sealing assembly 50 can seal the gap between the inner wall of the clearance opening 711 and the support member 30, so as to seal the outer edge of the clearance opening 711 on the housing 700 when the battery module 1 is engaged with the frame 70, so as to ensure the sealing of the receiving cavity when the electrical connector 41 is exposed from the clearance opening 711.

[0060] In some optional embodiments of the present invention, the power distribution assembly 40 includes a plurality of connectors 41, which are spaced apart from the support member 30.

[0061] Specifically, the battery module 1 has multiple connectors 41, including high-voltage connectors and low-voltage connectors. The multiple connectors 41 are integrated on the support member 30. On the one hand, this facilitates the electrical connection between the multiple connectors 41 and external components. On the other hand, it helps to reduce the space occupied by the multiple connectors 41, thereby improving the utilization rate of the internal space of the battery module 1.

[0062] The sealing assembly 50 is arranged around the plurality of connectors 41. The sealing assembly 50 is adapted to be located within the clearance opening 711 to seal against the inner wall of the clearance opening 711, thereby sealing the gap between the inner wall of the clearance opening 711 and the support member 30. This prevents external impurities from entering the receiving cavity through the gap between the inner wall of the clearance opening 711 and the support member 30, thus fully protecting the components inside the receiving cavity and preventing external impurities from contaminating or damaging the battery section 20 and the power distribution assembly 40 inside the receiving cavity.

[0063] In some optional embodiments of this utility model, such as Figure 4As shown, the sealing assembly 50 includes an annular mounting portion 53 and a first sealing ring 51. The mounting portion 53 is fixed to the support member 30 and is sealed to the support member 30. The first sealing ring 51 is sleeved on the mounting portion 53 and is located between the inner wall of the clearance opening 711 and the mounting portion 53. The first sealing ring 51 is used to fully seal the gap between the mounting portion 53 and the inner wall of the clearance opening 711.

[0064] Since the mounting part 53 and the support member 30 are sealed together, a first sealing ring 51 is provided between the mounting part 53 and the inner wall of the clearance opening 711 to fully seal the gap between the inner wall of the clearance opening 711 and the support member 30, so as to prevent external impurities from entering the receiving cavity and to prevent contamination or damage to the battery part 20 and the power distribution component 40 in the receiving cavity.

[0065] In some embodiments, such as Figure 4 As shown, the first sealing ring 51 is used to seal the gap between the inner wall of the clearance opening 711 and the mounting part 53. The size of the first sealing ring 51 can be designed according to the size of the clearance opening 711, and the thickness of the first sealing ring 51 can be designed according to the length of the inner wall of the clearance opening 711 and the distance between the clearance opening 711 and the support member 30, so that the first sealing ring 51 can fully seal the gap between the inner wall of the clearance opening 711 and the mounting part 53.

[0066] In some embodiments, the first sealing ring 51 may deform to absorb the assembly deviation between the inner wall of the clearance opening 711 and the mounting part 53, thereby enabling the mounting part 53 to be smoothly installed at the clearance opening 711, and the first sealing ring 51 can fully seal the gap between the mounting part 53 and the inner wall of the clearance opening 711.

[0067] In some specific embodiments of this utility model, such as Figure 4 As shown, the sealing assembly 50 also includes a second sealing ring 52, which is disposed on the side of the mounting portion 53 facing the support member 30. The second sealing ring 52 is located between the mounting portion 53 and the support member 30 to seal the gap between the mounting portion 53 and the support member 30.

[0068] Specifically, the first sealing ring 51 can seal the gap between the mounting part 53 and the inner wall of the clearance opening 711, and the second sealing ring 52 can seal the gap between the mounting part 53 and the support member 30. The sealing assembly 50 can fully seal the gap between the support member 30 and the inner wall of the clearance opening 711, preventing external impurities from entering the receiving cavity through the gap between the mounting part 53 and the inner wall of the clearance opening 711 and through the gap between the mounting part 53 and the support member 30, and preventing contaminants from contaminating or damaging the battery part 20 and the power distribution assembly 40 in the receiving cavity.

[0069] In some embodiments, such as Figure 4As shown, the second sealing ring 52 is arranged around the multiple connectors 41, and the size of the second sealing ring 52 can be designed according to the number and arrangement of the connectors 41.

[0070] In some embodiments, the second sealing ring 52 may deform to absorb assembly deviations between the support member 30 and the mounting portion 53, while simultaneously using the second sealing ring 52 to fully seal the gap between the support member 30 and the mounting portion 53.

[0071] In some other specific embodiments of this utility model, the side of the mounting part 53 facing the support member 30 is coated with sealant, and the side of the mounting part 53 facing the support member 30 is glued to the support member 30. At the same time, the sealant can fill the gap between the mounting part 53 and the support member 30 to fully seal the gap between the mounting part 53 and the support member 30.

[0072] In some embodiments, such as Figure 8 , Figure 9 As shown, the outer peripheral wall of the mounting part 53 is provided with a first groove 5311. The first groove 5311 is used to accommodate the first sealing ring 51 so that the first sealing ring 51 can be sleeved on the mounting part 53. The first groove 5311 is used to limit the position of the first sealing ring 51, so as to prevent the first sealing ring 51 from falling off the mounting part 53, and so that the first sealing ring 51 can fully seal the gap between the mounting part 53 and the inner wall of the clearance opening 711.

[0073] In some specific embodiments of this utility model, such as Figure 4 As shown, the mounting portion 53 includes an annular first portion 531 and an annular second portion 532. The second portion 532 intersects and connects with the end of the first portion 531 facing the support member 30. The second portion 532 protrudes toward the middle of the first portion 531. A first sealing ring 51 is provided on the first portion 531, and a second sealing ring 52 is provided on the second portion 532.

[0074] Specifically, the second part 532 protrudes toward the middle of the first part 531 so that the side of the mounting part 53 facing the support member 30 has a larger surface area, thereby increasing the mating area between the mounting part 53 and the support member 30 and improving the sealing reliability between the mounting part 53 and the support member 30.

[0075] In some embodiments, such as Figure 4 As shown, the vehicle's battery module 1 also includes a fastener 61, which passes through the second part 532 and the support member 30 to fix the mounting part 53 to the support member 30.

[0076] When the mounting part 53 is installed in the clearance opening 711, the position of the mounting part 53 can be moved so that the side of the mounting part 53 facing the support member 30 is sealed and engaged with the support member 30, and then the second part 532 and the support member 30 are fixed together by the fastener 61.

[0077] In some embodiments, such as Figure 4 , Figure 9 As shown, the outer periphery of the first part 531 is provided with an annular first groove 5311, and the first sealing ring 51 is disposed in the first groove 5311 to limit the position of the first sealing ring 51 and prevent the first sealing ring 51 from coming off the first part 531.

[0078] The second part 532 has an annular second groove 5321 on the side facing the support member 30. The second sealing ring 52 is disposed in the second groove 5321 to limit the position of the second sealing ring 52 and prevent the second sealing ring 52 from coming off the second part 532.

[0079] When the mounting part 53 is placed in the clearance opening 711, the first sealing ring 51 can seal the gap between the inner wall of the clearance opening 711 and the mounting part 53. At the same time, the position of the mounting part 53 in the clearance opening 711 can be adjusted so that the plane of the mounting part 53 facing the support member 30 abuts against the support member 30, so that the second sealing ring 52 can seal the gap between the mounting part 53 and the support member 30.

[0080] In some embodiments, such as Figure 4 , Figure 7 As shown, the support member 30 is provided with a mating blind hole 31, which is fixedly engaged with the fastener 61 so as to fix the mounting part 53 and the support member 30 together using the fastener 61.

[0081] Meanwhile, by using the matching blind hole 31 to fix the fastener 61, it is possible to avoid the formation of through holes on the support 30, and prevent external impurities from entering the receiving cavity through the gap between the fastener 61 and the through hole.

[0082] In some embodiments, such as Figure 4 , Figure 5 As shown, in the thickness direction of the second part 532, the fastener 61 is disposed to overlap at least part of the stop portion of the second part 532 and the second sealing ring 52, so that the fastener 61 applies force to the second sealing ring 52, thereby pressing the second sealing ring 52 so that the second sealing ring 52 can fully seal the gap between the support member 30 and the mounting part 53.

[0083] Specifically, the second part 532 and the second sealing ring 52 are sandwiched between the protruding head of the fastener 61 and the support member 30, so that the fastener 61 and the stop portion of the second part 532 and at least part of the second sealing ring 52 overlap, so that the clamping force of the fastener 61 on the second part 532 can be applied to the second sealing ring 52, thereby pressing the second sealing ring 52 and ensuring the sealing effect of the second sealing ring 52 on the second part 532 and the support member 30.

[0084] In some specific embodiments of this utility model, such as Figure 4 As shown, the support member 30 is provided with a mating groove 32, and the connector 41 extends into the mating groove 32 to reserve space for the installation of the connector 41 on the support member 30, so that the connector 41 can be installed on the support member 30. In this way, when the support member 30 and the clearance opening 711 on the housing 700 are directly opposite each other, the connector 41 can be exposed from the clearance opening 711.

[0085] A sealing gasket 62 is provided between the connector 41 and the support member 30 to seal the gap between the connector 41 and the support member 30, so as to prevent external contaminants from entering the receiving cavity through the gap between the connector 41 and the support member 30, and to prevent contaminants from causing pollution or damage to the battery section 20 or the power distribution assembly 40 in the receiving cavity.

[0086] In some embodiments, such as Figure 5 , Figure 7 As shown, the inner wall of the mating groove 32 is provided with a protruding first stop portion 33, and the outer periphery of the connector 41 is provided with a protruding second stop portion 411. The sealing gasket 62 is sandwiched between the first stop portion 33 and the second stop portion 411 to improve the sealing between the inner wall of the mating groove 32 and the outer periphery of the connector 41.

[0087] In some embodiments, such as Figure 5 As shown, the connector 41 extends into the mating groove 32, the first stop portion 33 and the second stop portion 411 are arranged in the axial direction of the mating groove 32, and the sealing gasket 62 is clamped between the first stop portion 33 and the second stop portion 411 to form a gap with a longer path between the first stop portion 33 and the second stop portion 411, further increasing the difficulty for contaminants to enter the receiving cavity through the gap between the connector 41 and the mating groove 32.

[0088] In some embodiments, the power distribution assembly 40 includes a plurality of connectors 41, some of which are high-voltage connectors and others are low-voltage connectors. The support member 30 is provided with a plurality of mating slots 32, and the plurality of connectors 41 are respectively disposed in the mating slots 32.

[0089] In some examples, the power distribution assembly 40 includes a power distribution section 42, a wiring harness 43, and a connector 41. The power distribution section 42 is electrically connected to the battery section 20, and the connector 41 is electrically connected to the power distribution section 42 via the wiring harness 43. Since the wiring harness 43 is made of a flexible material, the connector 41 needs to be supported by a support member 30.

[0090] In some examples, the battery module 1 also includes a fastener (not shown in the figure), and the support 30 and the connector 41 are fixedly connected by the fastener to fix the connector 41 on the support 30 and prevent the connector 41 from coming out of the mating slot 32.

[0091] The fasteners can be screws or bolts, etc.

[0092] The chassis device 7 according to an embodiment of the present invention is described below. Figure 1 , Figure 2 As shown, the chassis device 7 according to an embodiment of the present invention includes a frame 70, a connecting cover 80, and a battery module 1 of the vehicle according to the above embodiment of the present invention.

[0093] The frame 70 includes two first crossbeams 71 arranged along a first direction and two longitudinal beams 72 arranged along a second direction. The first direction is perpendicular to the second direction (it should be understood that the above direction is only for the convenience of describing the drawings and does not limit the actual setting position and direction of the battery module 1 of the vehicle). Each first crossbeam 71 is connected between the two longitudinal beams 72, and the connecting cover 80 is fixed to the frame 70.

[0094] The first crossbeam 71, the longitudinal beam 72, and the connecting cover 80 together define the housing 700. The clearance opening 711 is provided on the first crossbeam 71 and / or the longitudinal beam 72. The tray 10 is fixed to the housing 700 to fix the battery module 1 on the frame 70.

[0095] The clearance 711 is located on the first crossbeam 71 and / or the longitudinal beam 72. This way, when the external parts are electrically connected to the connector 41, the connection position of the external parts and the connector 41 can avoid occupying the space of the chassis in the vertical direction, thus avoiding affecting the arrangement of other structures on the chassis.

[0096] Specifically, by providing a clearance opening 711 on the first crossbeam 71 and / or the longitudinal beam 72, the connector 41 is exposed through the clearance opening 711, so that external components can be electrically connected to the connector 41 through the clearance opening 711, thereby enabling the battery unit 20 to supply power to external components.

[0097] According to the embodiment of the present utility model, the battery module 1 of the vehicle is provided with a support member 30 on the tray 10, and the support member 30 is used to support the connector 41, so that the connector 41 can be electrically connected to external parts through the clearance opening 711 on the frame 70, thus solving the problem of the electrical connector 41 in the CTC battery structure.

[0098] Other configurations and operations of the frame 70 according to embodiments of the present invention are known to those skilled in the art and will not be described in detail here.

[0099] In some embodiments of this utility model, the clearance opening 711 is provided on the first crossbeam 71.

[0100] Specifically, due to the limitations of the vehicle chassis space, the length of the longitudinal beam 72 is usually greater than the length of the first crossbeam 71. In addition to setting the first crossbeam 71, a second crossbeam can also be set between the two longitudinal beams 72 to ensure the overall strength of the frame 70. Therefore, the clearance 711 is set on the first crossbeam 71 to ensure the overall structural strength of the frame 70 and the load-bearing capacity of the frame 70.

[0101] In some embodiments, the frame 70 further includes a second crossbeam, the second crossbeam and the first crossbeam 71 are arranged along a first direction, and the first crossbeam 71 is connected between two longitudinal beams 72 to improve the overall structural strength of the frame 70.

[0102] In some embodiments, the open opening is the bottom opening of the housing 700, and the clearance opening 711 is an opening provided on the side of the housing 700. That is, the bottom opening and the clearance opening 711 are provided on two adjacent walls of the housing 700. This makes it convenient to observe the fit between the clearance opening 711 and the support member 30 from the bottom opening when the tray 10 is installed on the frame 70. This makes it easier to install the support member 30 to the clearance opening 711 and make the connector 41 protrude from the clearance opening 711.
