Detailed Embodiment

[0032] The following will describe the detailed embodiments of the present disclosure with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only for the purpose of illustrating and explaining the present disclosure, and are not used to limit the present disclosure.

[0033] In the present disclosure, unless otherwise stated, the orientation terms such as "upper, lower, left, right" generally refer to the usage state of the support member, and "inner, outer" refer to the contour of the support member itself. In addition, it should be noted that the terms such as "first, second" are used to distinguish one element from another, and do not have an order or importance. Additionally, in the description with reference to the accompanying drawings, the same reference numerals in different drawings represent the same elements.

[0034] The inventors have found through research that in the related art, a distribution box repair cover is installed on the upper cover of the battery pack, and the distribution box repair cover is fixed to the upper cover by screws. Since the upper cover is made of thin steel plate by stamping, it is prone to deformation under local stress. When the distribution box repair cover is installed by screws, the upper cover receives a downward pressing force, resulting in local deformation of the upper cover in this area, thereby causing uneven compression of the sealing foam between the distribution box repair cover and the upper cover, and there is a risk of sealing failure.

[0035] To solve the above technical problems, asFigures 1-4 As shown, the first aspect of the present disclosure provides a support member for supporting between the upper cover 1 of the battery pack and the tray 2 and / or the cold plate 3 of the battery pack. The support member 4 includes: a main body 5, a support portion 6, and a strengthening portion 7. Among them, the main body 5 is connected to the tray 2 and / or the cold plate 3 of the battery pack, the support portion 6 is connected to the main body 5 and supports the upper cover 1; the strengthening portion 7 is connected to the main body 5 and the support portion 6.

[0036] Through the above technical solution, by arranging a support member between the upper cover 1 of the battery pack and the tray 2 and / or the cold plate 3 of the battery pack. For example, when the support member 4 is arranged between the upper cover 1 of the battery pack and the cold plate 3 of the battery pack, the main body 5 in the support member 4 is arranged between the cold plate 3 of the battery pack and the upper cover 1, the main body 5 of the support member 4 is connected to the cold plate 3, the support portion 6 of the support member 4 supports the upper cover 1, and the strengthening portion 7 of the support member 4 connects the main body 5 and the support portion 6 to strengthen the supporting force of the support portion 6 on the upper cover 1. Thus, through the arrangement of the support member 4, stable support can be provided for the upper cover 1, avoiding local deformation of the upper cover 1 after being stressed, resulting in sealing failure of the battery pack at the upper cover 1 part. For example, the position where the support member supports the upper cover can be close to the repair cover of the distribution box, thereby avoiding local immutability of the upper cover due to the installation of the repair cover of the distribution box, thereby improving the overall sealing performance and safety of the battery pack. However, the present disclosure is not limited thereto, and the support member can also support at any suitable position of the upper cover, and the number of support members can also be one or more to support multiple positions of the upper cover simultaneously, for example.

[0037] It can be understood that the above setting of the support member 4 between the upper cover 1 of the battery pack and the cold plate 3 of the battery pack is illustrative. In other embodiments, the support member 4 can also be arranged between the upper cover 1 of the battery pack and the tray 2 of the battery pack, as long as the support portion 6 of the support member 4 can stably support the upper cover 1. Of course, in other embodiments, the support member 4 can also be arranged between the upper cover 1 of the battery pack, the tray 2 of the battery pack, and the cold plate 3. For example, a part of the main body 5 of the support member 4 is connected to the tray 2, and another part is connected to the cold plate 3. The support portion 6 of the support member 4 supports the upper cover 1, and through the strengthening portion 7, the supporting force of the support portion 6 on the upper cover 1 can be strengthened, so as to provide sufficient supporting force for the upper cover 1 to prevent the upper cover 1 from being deformed by stress.

[0038] It should be noted that in the present disclosure, the case where the support member 4 is arranged between the upper cover 1 of the battery pack and the cold plate 3 of the battery pack will be used as an example for elaboration.

[0039] In order to improve the supporting strength of the support member 4 on the upper cover 1, in some feasible embodiments, the support portion 6, the strengthening portion 7, and at least part of the main body 5 jointly form a polygonal strengthening structure. As Figure 2 、 Figure 3 and Figure 5As shown, the support member 4 is disposed between the upper cover 1 and the cold plate 3. The cold plate 3 can be a boat-shaped cold plate. The main body 5 is inclined and abuts against the side wall of the cold plate 3. The support portion 6 extends along the width direction of the cold plate and abuts against the upper cover 1. The first end of the support portion 6 is fixedly connected to the upper end of the main body 5, the second end of the support portion 6 is fixedly connected to the first end of the reinforcing portion 7, and the second end of the reinforcing portion 7 is fixedly connected to the middle portion of the main body 5. Thus, a polygonal reinforcing structure is jointly formed by the upper portion of the main body 5, the support portion 6 and the reinforcing portion 7 to improve the supporting strength of the upper cover 1. Of course, the structure in which the upper portion of the main body 5, the support portion 6 and the reinforcing portion 7 jointly form a polygonal reinforcing structure is illustrative. In other embodiments, it may also be that the whole main body 5, the support portion 6 and the reinforcing portion 7 jointly form a polygonal reinforcing structure. For example, the upper end of the main body 5 is fixedly connected to the first end of the support portion 6, the first end of the reinforcing portion 7 is fixedly connected to the second end of the support portion 6, and the second end of the reinforcing portion 7 is fixedly connected to the lower end of the main body 5.

[0040] In some implementable ways, the support portion 6 includes a support plate 61 for fitting the upper cover 1, and the reinforcing portion 7 includes a reinforcing plate 71. Both the support plate 61 and the reinforcing plate 71 can be rectangular. One end of the support plate 61 is fixedly connected to the main body 5, and the reinforcing plate 71 is fixedly connected between the other end of the support plate 61 and the main body 5. The polygonal reinforcing structure can be a triangular reinforcing structure. The support plate 61, the reinforcing plate 71 and at least part of the main body 5 jointly form the triangular reinforcing structure. As Figure 5 shown, the main body 5 is inclined and abuts against the cold plate 3. The two ends of the support plate 61 are respectively fixedly connected to the upper end of the main body 5 and the first end of the reinforcing plate 71 by welding, and the second end of the reinforcing plate 71 is fixedly connected to the middle portion of the main body 5 by welding. Thus, the support plate 61, the reinforcing plate 71 and the upper portion of the main body 5 jointly form a triangular reinforcing structure. In this way, when the support portion 6 supports the upper cover 1 through the setting of the triangular reinforcing structure, the support portion 6 can bear more loads, so that the support member 4 stably supports the upper cover 1 and prevents the upper cover 1 from deforming after being stressed. It can be understood that the above-mentioned polygonal reinforcing structure being a triangular reinforcing structure is illustrative. In other embodiments, the polygonal reinforcing structure can also be a quadrilateral or other polygons.

[0041] To facilitate the manufacture of the support member 4, in some implementable ways, the main body 5, the support portion 6 and the reinforcing portion 7 are configured as an integral part. For example, the support member 4 can be configured to be formed by integral die-casting or can be formed by rolling steel, so that the support member 4 is easy to manufacture. At the same time, the structure of the integrally provided support member 4 is more stable and the overall strength is higher, so that it can stably support the upper cover 1.

[0042] In some implementable ways, to facilitate the arrangement of the wire harnesses inside the battery pack and the routing of the wire harnesses, a wire harness fixing portion 8 is provided on the main body 5. The wire harness fixing portion 8 is used to fix the wire harness or fix the wire harness through a connecting member mounted on the wire harness fixing portion 8. For example, the wire harness fixing portion 8 can be a through hole and is arranged at intervals on the main body 5. The connecting member connected to the wire harness fixing portion 8 can be a cable tie, and the cable tie is snap-fitted in the through hole. The wire harness can be any wire harness. For example, it can be a low-voltage lead-out wire harness. The low-voltage lead-out wire harness can be fixed on the main body 5 by the restraint of the cable tie, thus facilitating the arrangement of the low-voltage lead-out wire harness and routing the low-voltage lead-out wire harness. Alternatively, in some embodiments, the wire harness can be directly fixed by the wire harness fixing portion without using a connecting member. For example, the wire harness fixing portion can include two oppositely arranged clamping jaws to clamp and fix the wire harness by the two clamping jaws. The present disclosure is not limited thereto.

[0043] In some implementable ways, the main body 5 is attached to the tray 2 and / or the cold plate 3. The main body 5 has a convex structure 9, and the wire harness fixing portion 8 is provided on the convex structure 9. Taking the main body 5 attached to the cold plate 3 as an example, the main body 5 has opposite first wall surface 51 and second wall surface 52. The first wall surface 51 is attached to the cold plate 3. The main body 5 can be fixedly connected to the cold plate 3 by welding or bonding. The main body 5 has a convex structure 9, and the wire harness fixing portion 8 is provided on the convex structure 9. The convex structure 9 protrudes from the second wall surface 52 and is concave with respect to the first wall surface 51 to form a groove 53 that is concave with respect to the first wall surface 51. The groove 53 is used to avoid the connecting member of the wire harness fixing portion 8, so as to facilitate the installation of the connecting member of the wire harness fixing portion 8 on the convex structure 9. In addition, the provision of the groove 53 can also allow a clamping member to clamp the convex structure 9, so as to facilitate the clamping member to clamp the main body 5 and the cold plate 3 for welding and fixing.

[0044] It can be understood that the above-mentioned attachment of the main body 5 to the cold plate 3 is illustrative. In other embodiments, the main body 5 can also be attached to the tray 2, as long as it can provide an installation position for the main body 5.

[0045] Of course, in some implementable ways, a positioning portion 10 is provided on the main body 5. When the support member 4 is fixed to the cold plate 3, the position of the support member 4 and the cold plate 3 can be positioned through the positioning portion 10, so as to facilitate the support member 4 to be fixed at a preset position on the cold plate 3, so that the support member 4 can support the upper cover 1.

[0046] Specifically, to facilitate the support of the upper cover 1 by the support member 4 while also facilitating the positioning and installation of the support member 4 and the cold plate 3, the support portion 6 is provided at the top end of the main body 5, and the positioning portion 10 is provided at the bottom end of the main body 5. In this way, by separately providing the support portion 6 and the positioning portion 10 at the top and bottom ends of the main body 5, the portion for positioning the main body 5 and the portion for supporting the upper cover 1 can be separated, avoiding interference between positioning and support. The positioning portion 10 is provided at the bottom end of the main body 5, enabling the support member 4 to be positioned with the cold plate 3. By providing the support portion 6 at the top end of the main body 5, the support member 4 can support the upper cover 1. Additionally, by providing the positioning portion 10 at the bottom end of the main body 5, the positioning portion 10 can also play a role in supporting the support member 4.

[0047] In some implementable ways, to facilitate the positioning of the support member 4 and the cold plate 3, the positioning portion 10 includes a positioning groove and / or a positioning protrusion. For example, the positioning portion 10 includes a positioning groove. The number of positioning grooves can be multiple and are arranged at intervals along the extending direction of the support member 4. The cold plate 3 is provided with mating protrusions corresponding to the positioning grooves one by one. Thus, the support member 4 can be assembled with the cold plate 3 by clamping the protrusion structure 9 of the support member 4 with a clamping member. When the support member 4 is in contact with the cold plate 3 and the positioning groove mates with the positioning protrusion, at this time, the support member 4 is located at a preset position of the cold plate 3, and the support portion 6 of the support member 4 supports the upper cover 1.

[0048] Of course, it can be understood that the above-described manner in which the positioning portion 10 is configured as a positioning groove is illustrative. In other embodiments, the positioning portion 10 can also be a positioning protrusion, and correspondingly, the cold plate 3 is provided with positioning grooves corresponding to the positioning protrusions one by one. In addition, in other embodiments, the positioning portion 10 can also be a combination of a positioning protrusion and a positioning groove. Of course, in this case, the cold plate 3 is provided with positioning grooves and positioning protrusions that cooperate with the positioning protrusion and the positioning groove in the positioning portion 10, so that the support member 4 can be accurately positioned with the cold plate 3, enabling the support member 4 to support the upper cover 1.

[0049] To facilitate the accommodation of excess or extruded solder and reduce sealing problems caused by positions such as the solder flow channel sealing surface, in some implementable ways, the main body 5 is welded to the cold plate 3. The main body 5 can be fixedly connected to the cold plate 3 by brazing. The main body 5 is provided with solder receiving grooves 11. The number of solder receiving grooves 11 can be multiple. The solder receiving grooves 11 can be a strip-shaped hole or multiple strip-shaped holes arranged at intervals. In this way, through the provision of the solder receiving grooves 11, excess solder can be accommodated, reducing sealing problems caused by positions such as the solder flow channel sealing surface.

[0050] Of course, it can be understood that the above-mentioned main body 5 can also be welded to the tray 2. Through the solder receiving groove 11 provided on the main body 5, excess solder can be accommodated, reducing sealing problems caused by positions such as the solder flow path sealing surface.

[0051] In some implementable ways, in order to facilitate the fixed connection between the support member 4 and the cold plate 3, an avoidance portion 12 is provided on the main body 5. The shape of the avoidance portion 12 can be set according to the shape of the lead-out interface of the battery pack. For example, the avoidance portion 12 can be a rectangular notch. The avoidance portion 12 can avoid the lead-out interface of the battery pack. In this way, by avoiding the setting of the support member 4, the lead-out interface of the battery pack can be avoided, facilitating the positioning and fixed connection between the support member 4 and the cold plate 3.

[0052] In order to enable the support member 4 to avoid the lead-out interface of the battery pack and not affect the support for the upper cover 1, in some implementable ways, the avoidance portion is spaced apart from the support portion 6 and / or the strengthening portion 7. For example, the avoidance portion 12 can be located below the support portion 6 and the strengthening portion 7. In this way, the avoidance portion 12 is located below the support portion 6 and the strengthening portion 7, so as to avoid the lead-out interface of the battery pack, facilitating the positioning and fixed connection between the support member 4 and the cold plate 3. At the same time, the setting of the avoidance portion 12 does not reduce the sizes of the support portion 6 and the strengthening portion 7, so that the cooperation between the support portion 6 and the strengthening portion 7 provides stable support for the upper cover 1.

[0053] The second aspect of the present disclosure provides a battery pack, including an upper cover 1, a tray 2, a cold plate 3, and the above-mentioned support member 4. The support member 4 is attached to the tray and / or the cold plate 3. The upper cover 1 is fixedly connected to the tray 2, and the cold plate 3 is disposed between the tray 2 and the upper cover 1. In this way, by providing the support member 4 between the upper cover 1 of the battery pack and the tray 2 and / or the cold plate 3 of the battery pack. For example, when the support member 4 is disposed between the upper cover 1 of the battery pack and the cold plate 3 of the battery pack, the main body 5 in the support member 4 is disposed between the cold plate 3 of the battery pack and the upper cover 1 of the battery pack. The main body 5 of the support member 4 is connected to the cold plate 3. The support portion 6 of the support member 4 supports the upper cover 1. The strengthening portion 7 of the support member 4 connects the main body 5 and the support portion 6 to strengthen the supporting force of the support portion 6 on the upper cover 1. Thus, through the setting of the support member 4, stable support can be provided for the upper cover 1, avoiding local deformation of the upper cover 1 after being stressed, resulting in sealing failure of the battery pack in the upper cover 1 part.

[0054] The distribution box is a core component in the battery pack. To facilitate the placement of the distribution box in the battery pack and the repair of the distribution box, the battery pack further includes a distribution box repair cover 13. The upper cover 1 has an installation part 14 for installing the distribution box repair cover 13. Among them, the installation part 14 can be an installation opening provided on the distribution box repair cover 13. The support part 6 is supported at a support position of the upper cover 1 adjacent to the second installation part 14. The distribution box repair cover 13 can be fixedly connected to the upper cover 1 by screws. Thus, when it is necessary to repair or replace the distribution box in the battery pack, the screws can be rotated to separate the distribution box repair cover 13 from the upper cover 1. During the installation process of the distribution box repair cover 13, since the upper cover 1 is a relatively thin steel plate, part of the upper cover 1 is prone to deformation when installing the screws. By arranging the support part 6 at a support position of the upper cover 1 adjacent to the second installation part 14, the strength of the upper cover 1 at this position can be enhanced, and stable support can be provided for the upper cover 1, avoiding local deformation of the upper cover 1 after being stressed, resulting in the sealing failure of the battery pack at the upper cover 1 part.

[0055] In some implementable ways, the support part 6 is bonded to the upper cover 1. For example, the support part 6 can be bonded to the upper cover 1 through structural adhesive. In this way, the support part 6 can not only play a supporting role for the upper cover 1, but also provide partial adhesive force when the battery pack vibrates, avoiding the upward movement of the upper cover 1 and improving the structural strength of the upper cover 1.

[0056] To facilitate the connection between the cold plate 3 and the support member 4, in some implementable ways, the cold plate 3 has a side plate section 31 that extends obliquely towards the upper cover 1. The first wall surface 51 of the main body 5 is fitted and supported on the side plate section 31. Thus, through the setting of the side plate section 31, enough installation space can be formed between the cold plate 3 and the upper cover 1 to install the support member 4. In particular, the support plate 61, the reinforcement plate 71 and the main body 5 in the support member 4 together form a triangular reinforcement structure. In addition, through the setting of the side plate section 31, it is also convenient to place the support member 4 as a whole into the battery pack and fix the support member 4 to the cold plate 3 by welding.

[0057] Of course, the connection between the cold plate 3 and the support member 4 described above is illustrative. In other embodiments, the support member 4 is fitted to the tray 2. The tray 2 has a side plate section 31 that extends obliquely towards the upper cover 1. The first wall surface 51 of the main body 5 is fitted and supported on the side plate section 31. Thus, through the setting of the side plate section 31, enough installation space can be formed between the tray 2 and the upper cover 1 to install the support member 4.

[0058] In addition, to facilitate the positioning of the support member 4 and the cold plate 3, in some implementable embodiments, a mating portion connected to the positioning portion 10 on the main body 5 is provided on the side plate section 31, and the mating portion is configured as a mating protrusion and / or a mating groove. For example, when the positioning portion 10 on the main body 5 is configured as a positioning groove, the mating portion on the side plate section 31 is a mating protrusion corresponding one-to-one to the mating groove. When the support member 4 and the cold plate 3 are installed, first, the groove 53 of the support member 4 is clamped by the clamping member and moved to insert and position the mating groove and the mating protrusion, so that the support member 4 can be accurately positioned with the cold plate 3, so that the support member 4 can support the upper cover 1, thereby preventing the upper cover 1 from deforming under force, resulting in the sealing failure of the battery pack in the upper cover 1 part, thereby improving the overall sealing performance and safety of the battery pack.

[0059] The third aspect of the present disclosure provides an electrical device including the above-mentioned battery pack. It can be understood that the electrical device can be a pure electric vehicle, a hybrid vehicle, or any other suitable vehicle or device with a battery pack. By providing the support member 4 in the above battery pack, the overall sealing performance and safety of the battery pack can be improved. Thus, the safety and stability of the vehicle using the above battery pack are also correspondingly improved.

[0060] The preferred embodiments of the present disclosure have been described in detail above in conjunction with the accompanying drawings. However, the present disclosure is not limited to the specific details in the above embodiments.

[0061] In addition, it should be noted that, in the above specific embodiments, the various specific technical features described can be combined in any suitable manner without contradiction.
