[0036] The following is for reference. Figures 1-6 A support assembly 100 according to an embodiment of the present invention is described.

[0037] According to the bracket assembly 100 of the present invention, the bracket assembly 100 includes a bracket 1, the bracket 1 having a plurality of mounting portions 2 for mounting electrical connectors 3; the plurality of mounting portions 2 are spaced apart along a first direction. Specifically, the bracket 1 can be made of an insulating material, such as plastic, rubber, ceramic, etc., or it can be made of a metal material coated with an insulating material. Two or more mounting portions 2 can be provided on the bracket 1, corresponding to the mounting of two or more electrical connectors 3. The electrical connectors 3 can be connecting bars of opposite polarity or connecting bars of the same polarity in the battery device 200. By spaced apart along the first direction, a safe distance can be maintained between the electrical connectors 3, effectively avoiding short circuits or arcing. It should be noted that the first direction can be the width direction or the length direction of the bracket 1, and is not limited here. In some embodiments, the plurality of mounting portions 2 can be provided on both sides of the bracket 1 along the first direction, or the plurality of mounting portions 2 can penetrate the bracket 1, as long as the plurality of mounting portions 2 can be spaced apart, and is not limited here. In some embodiments, the mounting part 2 can be a snap fastener that can hold the electrical connector 3, or it can be a through hole or a slot that can be installed by passing the electrical connector 3 through the through hole or slot. The mounting part 2 can also be an adhesive layer, as long as it can install the electrical connector 3, and there is no limitation here.

[0038] According to the bracket assembly 100 of the present invention, a plurality of electrical connectors 3 are respectively installed on a plurality of mounting portions 2, and the plurality of mounting portions 2 are spaced apart along a first direction, so that the plurality of electrical connectors 3 are spaced apart, which can ensure that a safe distance is maintained between the electrical connectors 3, and the plurality of electrical connectors 3 are not easy to contact each other, preventing short circuits and arcing between the electrical connectors 3, and improving the safety performance of the battery device 200 and the electrical equipment.

[0039] According to some embodiments of the present invention, the mounting portion 2 is constructed as at least one of a mounting hole or a mounting groove. Specifically, multiple mounting portions 2 can be mounting grooves, which penetrate the bracket 1, and the electrical connector 3 passes through the mounting groove. As shown in the accompanying drawings, in this embodiment, two mounting portions 2 are provided, and both mounting portions 2 are mounting grooves. In other embodiments, multiple mounting portions 2 can be mounting holes, which penetrate the bracket 1, and the electrical connector 3 passes through the mounting hole; or multiple mounting portions 2 can be a combination of a mounting hole and a mounting groove. The structural design of the mounting hole or mounting groove facilitates the fixing and disassembly of the electrical connector 3. According to some embodiments of the present invention, the mounting portion 2 penetrates the bracket 1 along a second direction, which intersects with the first direction. Specifically, the second direction may be the width direction of the bracket 1, and the first direction may be the length direction of the bracket 1, with the first and second directions perpendicular to each other. In other embodiments, the second direction is inclined relative to the first direction, suitable for different application scenarios. The through-through design in the second direction forms a through-structure, facilitating the insertion of the electrical connector 3 from both sides of the bracket 1, while also ensuring the stability of the electrical connector 3.

[0040] According to some embodiments of the present invention, the bracket 1 is provided with a cavity 11, and the mounting part 2 penetrates through two opposite side walls 12 of the cavity 11 along the second direction, so as to form sub-mounting parts 2 on the two side walls 12 respectively. Specifically, the bracket 1 is constructed as a hollow structure, and a cavity 11 is formed inside the bracket 1. The cavity 11 has multiple side walls 12. Since the mounting part 2 penetrates the bracket 1 along the second direction, that is, penetrates the cavity 11, a portion of the electrical connector 3 is simultaneously installed in the cavity 11. Different electrical connectors 3 located in the cavity 11 can be protected and air-isolated, improving safety. At the same time, two sub-mounting parts 2 are formed on the two opposite side walls 12 of the cavity 11 along the second direction, which can be used for double installation of the electrical connector 3, facilitating the positioning and installation of the electrical connector 3.

[0041] According to some embodiments of the present invention, an insulating isolator 4 is provided inside the cavity 11, and the insulating isolator 4 is disposed between two adjacent mounting portions 2 to isolate multiple electrical connectors 3. Specifically, the insulating isolator 4 can be made of a highly insulating material, such as ceramic, quartz glass, alumina, plastic, etc.; the insulating isolator 4 can be connected to the inner wall of the cavity 11 by means of bonding, snap-fitting, plugging, etc., and is located between two adjacent mounting portions 2. With this arrangement, when the electrical connectors 3 are installed in the mounting portions 2, the insulating isolator 4 is located between two adjacent electrical connectors 3, and the insulating isolator 4 can effectively block the electrical gap between the electrical connectors 3, and at the same time, it is beneficial to prevent breakdown under high electric field strength, eliminating the risk of electrical gap breakdown under extreme working conditions (such as vibration, thermal expansion).

[0042] According to some embodiments of the present invention, the insulating isolator 4 is engaged with the inner wall hole of the cavity 11. Specifically, one of the insulating isolator 4 and the inner wall of the cavity 11 is provided with an insertion hole and the other is provided with a pin. In the embodiments of this application, the inner bottom wall of the cavity 11 is provided with a pin, and the bottom surface of the insulating isolator 4 is provided with an insertion hole. The hole-pin engagement structure facilitates installation and positioning.

[0043] According to some embodiments of the present invention, the insulating separator 4 is made of at least one of oxide ceramics and nitride ceramics. Specifically, the insulating separator 4 can be made of oxide ceramics, such as alumina ceramics; the insulating separator 4 can also be made of nitride ceramics, such as silicon nitride ceramics; or the insulating separator 4 can be made of a mixture of oxide ceramics and nitride ceramics, further improving the insulation performance between the electrical connectors 3.

[0044] According to some embodiments of the present invention, the volume resistivity of the insulating separator 4 is greater than or equal to 1×10 14 Ω·cm. Specifically, the volume resistivity of insulating element 4 is 1×10⁻⁶. 14 Ω·cm, 1.2×10 14 Ω·cm, 1.5×10 14 Ω·cm, 2×10 14 Ω·cm and 3×10 14 Ω·cm, etc., can effectively block the electrical gap between electrical connectors 3 and prevent breakdown.

[0045] According to some embodiments of the present invention, the insulating insulating element 4 has a temperature resistance greater than or equal to 1600°C. Specifically, the temperature resistance of the insulating insulating element 4 can be 1600°C, 1700°C, 1800°C, 1900°C, 2000°C, etc., which can prevent the insulating insulating element 4 from melting in high-temperature environments such as thermal runaway, thus providing safety performance.

[0046] According to some embodiments of the present invention, the insulating spacer 4 extends along the second direction and has a gap with at least one sidewall 12. Specifically, the insulating spacer 4 is attached to one sidewall 12 along the second direction, and the insulating spacer 4 is spaced apart from another sidewall 12 along the other side of the second direction, or the insulating spacer 4 is spaced apart from the sidewall 12 on both sides along the second direction. This design can reserve an expansion gap between the insulating spacer 4 and the support 1 to accommodate differences in material thermal deformation.

[0047] According to some embodiments of the present invention, the gap ranges from greater than or equal to 0.5 mm to less than or equal to 1 mm. Specifically, the gap can be 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm, 0.9 mm, and 1 mm, etc. This setting can satisfy the expansion gap and also allow the insulating insulating member 4 to be located more between adjacent electrical connectors 3.

[0048] According to some embodiments of the present invention, the width of the insulating isolator 4 along the first direction is greater than 19.1 mm. Specifically, the width of the insulating isolator 4 along the first direction can be 19.2 mm, 20 mm, etc., which can meet the requirements of the calculated value of the electrical clearance standard in GB / T 16935.1-2008.

[0049] According to some embodiments of the present invention, a first sealing element 5 is also included. The cavity 11 is used to fill an insulating medium. The first sealing element 5 is provided with a clearance hole 51 for the electrical connector 3. The first sealing element 5 is disposed in the sub-mounting part 2 to seal between the side wall 12 and the sub-mounting part 2. Specifically, the cavity 11 can be filled with insulating colloid, insulating plastic, etc., to further insulate the multiple electrical connectors 3. At the same time, when the bracket 1 is applied in the battery device 200, the insulating medium can also seal the two receiving cavities to prevent cross-contamination. When the electrical connector 3 is installed in the sub-mounting part 2, there is a gap between the electrical connector 3 and the sub-mounting part 2. Since the insulating medium is initially fluid, the first sealing element 5 can seal the gap between the electrical connector 3 and the sub-mounting part 2, preventing the insulating medium from flowing out and facilitating assembly and manufacturing.

[0050] According to some embodiments of the present invention, the first sealing member 5 is provided with at least one first flange 52, and the first sealing member 5 is fitted into the sub-mounting portion 2 so that the first flange 52 is in a limiting engagement with at least one side of the sidewall 12 along the second direction. Specifically, in the embodiments of this application, such as Figure 3 The first sealing member 5 has two first flanges 52, with a gap between them to allow the first sealing member 5 to fit into the side wall 12, thus ensuring that the first flanges 52 and the side wall 12 are locked in place and that the first sealing member 5 is fixed in place. In another embodiment of this application, such as Figure 2The two first seals 5 on the two sub-mounting parts 2 opposite to each other along the second direction can be integrally formed. The first flange 52 of one first seal 5 is located on the outer side of one side wall 12 along the second direction, and the first flange 52 of the other first seal 5 is located on the outer side of the other side wall 12 along the second direction. This arrangement can ensure that the first seals 5 can be fixed and not fall off.

[0051] According to some embodiments of the present invention, the first sealing element 5 is a silicone component. Silicone has good elasticity and high temperature resistance, which facilitates the installation of the electrical connector 3 and improves high-temperature safety. In other embodiments, the first sealing element 5 may be made of rubber, plastic, or the like.

[0052] According to some embodiments of the present invention, the temperature resistance range of the first seal 5 is greater than or equal to -65°C and less than or equal to 250°C. Specifically, the temperature resistance range of the first seal 5 can be -65°C, -40°C, 0°C, 20°C, 80°C, 150°C, 200°C, and 250°C, etc., so that the first seal 5 can be adapted to different high and low temperature environments.

[0053] According to some embodiments of the present invention, the cavity 11 has an opening facing a third direction, and the support assembly 100 further includes a protective cover 6, which covers the opening and is connected to the support 1. The third direction, the second direction, and the first direction intersect each other. Specifically, the third direction can be the height direction of the support 1, that is, the cavity 11 opens upward toward the support 1, which facilitates the injection of sterilization medium and prevents leakage. The protective cover 6 can be connected to the support 1 by means of adhesive, snap-fit, screw, etc., and close the opening, which facilitates the protection of the electrical connectors 3 inside the cavity 11.

[0054] According to some embodiments of the present invention, a second sealing element 7 is further included. The second sealing element 7 is disposed around the opening and sealed between the protective cover 6 and the bracket 1. The bracket 1 has a second flange around the opening, and the second sealing element 7 is disposed inside the second flange. Specifically, the second sealing element 7 is an annular sealing element, and the second flange is an annular flange. The second sealing element 7 abuts between the protective cover 6 and the bracket 1 to prevent the insulating medium from overflowing. The second sealing element 7 is located inside the second flange, which can limit the second sealing element 7 to prevent it from being misaligned and affecting the sealing effect. The second sealing element 7 can be sealed to the protective cover 6 and the bracket 1 by adhesive bonding.

[0055] According to some embodiments of the present invention, the second sealing element 7 is a ceramicized silicone foam component. Under high-temperature environments such as thermal runaway, the ceramicized silicone foam component can form a ceramic layer to maintain sealing performance.

[0056] According to some embodiments of the present invention, the inner wall of the second flange is inclined in a direction away from the second seal 7 and forms an angle with a third direction. The inclined orientation of the inner wall of the second flange towards the direction away from the second seal 7 further prevents the leakage of the insulating medium and also provides guidance for the installation of the second seal 7. Furthermore, the angle is greater than or equal to 5° and less than or equal to 25°. Specifically, the angle can be 5°, 8°, 10°, 15°, 20°, or 25°. An angle that is too small will not provide the functions of preventing leakage and guiding, while an angle that is too large will affect the wall thickness and structural strength.

[0057] According to some embodiments of the present invention, the bracket 1 is provided with a first snap-fit ​​portion 14, and the protective cover 6 is provided with a second snap-fit ​​portion 61, the first snap-fit ​​portion 14 and the second snap-fit ​​portion 61 engaging with each other. Specifically, in the embodiments of this application, the bracket 1 is provided with a first snap-fit ​​portion 14 at both ends along the second direction, and the protective cover 6 is provided with a second snap-fit ​​portion 61 at both ends along the second direction. The bracket 1 and the protective cover 6 are engaged with each other through the first snap-fit ​​portion 14 and the second snap-fit ​​portion 61, which improves the ease of installation.

[0058] According to some embodiments of the present invention, the protective cover 6 is provided with an injection hole 62, which communicates with the cavity 11. In the initial state, the insulating medium is liquid, and the injection hole 62 on the protective cover 6, which communicates with the cavity 11, facilitates improved injection efficiency. According to some embodiments of the present invention, the protective cover 6 is provided with an observation hole 63, which communicates with the cavity 11. The observation hole 63 has at least one overflow groove 64 circumferentially arranged therefrom. Specifically, the protective cover 6 is provided with an observation hole 63, which allows observation of the filling status inside the cavity 11, preventing both insufficient and excessive filling. Furthermore, the observation hole 63 may have at least one overflow groove circumferentially arranged. This allows for setting a filling amount that meets requirements when the insulating medium overflows from the overflow groove, and also prevents the insulating medium from overflowing to the outside, thus improving filling efficiency.

[0059] According to some embodiments of the present invention, the protective cover 6 has a wire harness slot 65 on the side opposite to the bracket 1. When the bracket assembly 100 is applied to the battery device 200 or electrical equipment, the wire harness slot 65 on the protective cover 6 can be used to secure communication wire harnesses, etc. The integrated wire harness slot 65 in the protective cover 6 reduces cost and installation difficulty.

[0060] According to some embodiments of the present invention, the bracket 1 has a mounting groove 15 on the side opposite to the protective cover 6. When the bracket assembly 100 is applied to the battery device 200 or electrical equipment, the bracket 1 can be mounted on the structural components of the battery device 200 or electrical equipment through the mounting groove 15, thereby improving installation reliability and installation efficiency.

[0061] According to a second aspect embodiment of the present invention, a battery device 200 includes a support assembly 100 according to any embodiment of the first aspect, a battery pack 8, and a plurality of electrical connectors 3, wherein the electrical connectors 3 are electrically connected to the battery pack 8 and are connected to a mounting portion 2. Specifically, the battery device 200 may be a battery pack or an automotive chassis (CTC technology), etc. The battery pack 8 may be one or more.

[0062] According to a second aspect embodiment of the present invention, in the battery device 200, a plurality of electrical connectors 3 are respectively mounted on a plurality of mounting portions 2, and the plurality of mounting portions 2 are spaced apart along a first direction, so that the plurality of electrical connectors 3 are spaced apart and the plurality of electrical connectors 3 are not easy to contact each other, thereby preventing short circuits and arcing between the electrical connectors 3, and the battery device 200 has high safety performance.

[0063] According to some embodiments of the present invention, the housing 9 is further included.
