Description

Technical Field

[0001] The utility model relates to the field of batteries, in particular to a battery box, a battery and an injection mold. Background Art

[0002] Batteries are used to store electrical energy and can be used alone or in combination. Combination use allows multiple batteries to be arranged in sequence in a pre-opened space, or multiple batteries to be arranged on a support structure such as a rack or cabinet. Of course, different installation and setting methods can also be adopted according to different application scenarios and usage requirements.

[0003] The heat dissipation effect of the battery during actual use is particularly important. It is necessary to avoid the internal temperature of the battery box being too high, which may affect the service life, safety of use and product performance. The batteries in the related art usually dissipate heat through fans, but the air guide channel provided in conjunction with the fan will cause the product's protection level to be low. The reason is that the air guide channel needs to be connected to the outside of the battery box to guide the airflow to flow inside the battery box for heat dissipation. If the battery box is configured as a closed design, although it can improve the protection level of the battery and improve the waterproof and dustproof performance, the battery will instead cause the temperature to be too high due to the cancellation of the fan heat dissipation structure.

[0043] Figure 1 The battery box 10 in some embodiments of the present invention is shown. The battery box 10 is used to store battery cells and related components. Figures 1 to 4 As shown, the battery box 10 includes a cover body 1, a heat conducting plate 2 and a connecting structure 3; the cover body 1 is provided with a relief groove 11 (the relief groove 11 is shown in FIG. Figure 3 ), the bottom of the avoidance groove 11 is provided with a mounting through hole 12 (the mounting through hole 12 is shown in Figure 4 ).

[0044] It can be understood that the cover 1 plays a role of shielding and protection. The avoidance groove 11 can be configured to be set on the side of the cover 1 closer to the battery cell, and the installation through hole 12 passes through the two opposite sides of the cover 1. The heat conducting plate 2 is used to conduct heat. The connecting structure 3 is used to connect the heat conducting plate 2 and the cover 1.

[0045] like Figure 3 and Figure 4 As shown, the heat conducting plate 2 is arranged in the mounting through hole 12, the peripheral side wall a of the heat conducting plate 2 is adapted to the hole wall b of the mounting through hole 12, the peripheral side wall a of the heat conducting plate 2 and the groove wall c of the avoidance groove 11 jointly define a sealing groove 21, and a sealing rubber layer 22 is arranged in the sealing groove 21, and the sealing rubber layer 22 is respectively connected to the groove wall c of the sealing groove 21 and the peripheral side wall a of the heat conducting plate 2.

[0046] It can be understood that since the mounting through hole 12 passes through the cover body 1, the heat conducting plate 2 arranged in the mounting through hole 12 can respectively perform heat exchange on the upper and lower sides of the cover body 1, thereby exporting the heat in the battery box 10 to the outside. The heat conducting plate 2 is plate-shaped, and its upper and lower surfaces are used for the main heat exchange, and the peripheral side wall a is located between the upper and lower surfaces. The contour of the peripheral side wall a is adapted to the contour of the hole wall b, that is, the peripheral side wall a and the hole wall b are in surface contact, thereby avoiding excessive fitting gaps or fitting intervals between the peripheral side wall a and the hole wall b, and making the two fit as closely as possible, thereby improving the sealing between the peripheral side wall a and the hole wall b. The sealant layer 22 plays a role of further sealing and isolation, further isolating the intrusion of dust and liquid.

[0047] like Figure 3 and Figure 4 As shown, the connection structure 3 includes a protrusion 31 and a mounting groove 32 (the protrusion 31 and the mounting groove 32 are shown in FIG. Figure 4 ), the protrusion 31 is inserted into the mounting groove 32, the protrusion 31 is adapted to the mounting groove 32, one of the protrusion 31 and the mounting groove 32 is arranged on the peripheral side wall a of the heat conducting plate 2, and the other of the protrusion 31 and the mounting groove 32 is arranged on the hole wall b of the mounting through hole 12.

[0048] It can be understood that the plug-in fit between the protrusion 31 and the mounting groove 32 can position the heat conducting plate 2 in the mounting through hole 12. The profile of the protrusion 31 is adapted to the profile of the groove wall c of the mounting groove 32, so that each position of the protrusion 31 is in contact with the groove wall c, thereby eliminating the matching gap between the protrusion 31 and the mounting groove 32 as much as possible.

[0049] It should be noted that the raised portion 31 may be configured to include a plurality of raised portions distributed at intervals, or the raised portion 31 may be configured to have a uniform shape without any discontinuous positions.

[0050] like Figures 1 to 4 As shown, in some embodiments of the battery box 10, the battery box 10 also includes a base 4, a cover 1 is disposed on the base 4, and the cover 1 and the base 4 together define a receiving cavity 41; the avoidance groove 11 is located on the side of the cover 1 facing the receiving cavity 41.

[0051] It can be understood that the seat body 4 includes a bottom plate 42 and a plurality of side plates 43 arranged along the periphery of the bottom plate, and each side plate 43 is connected in sequence to form a ring, so that the seat body 4 has an upward opening 44. The accommodating cavity 41 serves to store the battery cells and other components on the battery. The avoidance groove 11 is exposed in the accommodating cavity 41, so that the sealant layer 22 is also exposed in the accommodating cavity 41, thereby avoiding the sealant layer 22 from being exposed outside the battery box 10 and being worn, etc., and ensuring the sealing effect of the sealant layer 22.

[0052] like Figure 3 and Figure 4 As shown, in some embodiments of the battery box 10 , the battery box 10 further includes a thermally conductive adhesive layer 5 , and the thermally conductive adhesive layer 5 is disposed on the side of the heat conductive plate 2 facing the accommodating cavity 41 .

[0053] It can be understood that the thermally conductive adhesive layer 5 plays a role in transferring heat. Specifically, the thermally conductive adhesive layer 5 can be configured to be formed by various common adhesives that can be used for heat conduction in the prior art. More specifically, the corresponding thermally conductive adhesive is filled or coated on the thermally conductive plate 2, and after the thermally conductive adhesive is cured, a thermally conductive adhesive layer 5 with excellent thermal conductivity can be formed.

[0054] Preferably, the heat-conducting adhesive layer 5 can be configured as an organic silicon adhesive flame retardant adhesive layer. The organic silicon adhesive flame retardant adhesive layer has excellent thermal conductivity and can quickly transfer heat.

[0055] like Figure 3 and Figure 4 As shown, in some embodiments of the battery box 10 , an annular mounting groove 32 is provided along the peripheral side wall a of the heat conducting plate 2 , and the protrusion 31 is annular and is disposed on the hole wall b of the mounting through hole 12 .

[0056] It can be understood that the mounting groove 32 is configured to be connected end to end after being extended around the peripheral side wall a of the heat conducting plate 2, so that the mounting groove 32 is annular. Correspondingly, the protrusion 31 also extends along the center of the mounting through hole 12 around the hole wall b and then connected end to end, so that the protrusion 31 is also annular.

[0057] like Figure 3 As shown, in some embodiments of the battery box 10 , a plurality of structural ribs 13 are disposed on the cover 1 , and at least a portion of the structural ribs 13 enclose a position-avoiding groove 11 on the surface of the cover 1 .

[0058] It can be understood that the structural ribs 13 play a reinforcing role, improving the strength and durability of the cover body 1. In this embodiment, the avoidance groove 11 is configured to be surrounded by the structural ribs 13, avoiding the avoidance groove 11 from being formed by reducing the thickness of the cover body 1, and ensuring the strength of the setting position of the avoidance groove 11.

[0059] like Figures 1 to 3 As shown, in some embodiments of the battery box 10, the heat conducting plate 2 includes an aluminum plate. It can be understood that the aluminum plate refers to a pure aluminum plate, and aluminum has excellent thermal conductivity and can effectively improve the heat dissipation effect of the battery box 10.

[0060] In some embodiments of the battery box 10, the heat conducting plate 2 comprises an aluminum alloy plate. It can be understood that the aluminum alloy plate is made of an aluminum alloy material, which has higher strength and avoids deformation, and also has excellent thermal conductivity.

[0061] In some embodiments of the battery box 10, the heat conducting plate 2 includes a copper plate. It can be understood that the copper plate has excellent thermal conductivity, and the use of the heat conducting plate 2 made of copper can improve the heat dissipation effect.

[0062] In some embodiments of the battery box 10, the heat conducting plate 2 includes a graphene plate. It can be understood that the graphene plate is made of graphene material, and graphene has good thermal conductivity.

[0063] The connection between the cover 1 and the heat conducting plate 2 has at least the following embodiments:

[0064] In a first embodiment, the cover 1 is injection molded on the heat conducting plate 2 .

[0065] It can be understood that the injection-molded cover body 1 will make the molded cover body 1 and the heat conducting plate 2 fit more tightly, further improving the sealing performance of the connection position between the two.

[0066] It should be noted that the heat conducting plate 2 and the cover body 1 are made of different materials and have different shrinkage rates, so there may be a certain gap between the contact positions of the two. However, in a further embodiment, by providing a sealant layer 22, the gap between the two can be further sealed to ensure the sealing protection performance and reach the IP67 protection level.

[0067] In a second embodiment, the battery box 10 further includes a snap-fit ​​member, and the cover 1 is connected to the heat conducting plate 2 via the snap-fit ​​member.

[0068] It is understandable that the buckle connection through the buckle piece can improve the assembly convenience of the two. The cover body 1 can be configured to be arranged on the cover body 1 or the heat conducting plate 2. Of course, a buckle position that is clamped with the buckle piece also needs to be opened at the corresponding position.

[0069] In a third embodiment, the battery box 10 further includes a screw member, and the cover 1 is connected to the heat conducting plate 2 via the screw member.

[0070] It can be understood that the threaded member can be configured to penetrate the cover 1 and be screwed to the heat conducting plate 2, or the threaded member can be configured to penetrate the heat conducting plate 2 and be screwed to the cover 1. The threaded member can be configured as a bolt, a screw or other threaded connector in the prior art.

[0071] Figure 4 A battery 20 is shown. The battery 20 includes a battery box 10 and a plurality of battery cells 30 . The battery cells 30 are arranged in sequence. A cover 1 is disposed on each battery cell 30 , and a heat conducting plate 2 faces each battery cell 30 .

[0072] It can be understood that the battery cells 30 are used to store electric energy. The cover 1 is located above each battery cell 30 , and the heat of each battery cell 30 is transferred to the heat conducting plate 2 , and then further transferred to the outside through the heat conducting plate 2 .

[0073] like Figure 4 As shown, in some embodiments of the battery 20, the battery 20 also includes a circuit board 40, which is arranged between the cover 1 and each battery cell 30, each battery cell 30 is connected to the circuit board 40, and the heat conducting plate 2 is respectively abutted against the circuit board 40 and each battery cell 30, so that the heat conducting plate 2 exchanges heat with the circuit board 40 and each battery cell 30 respectively.

[0074] It can be understood that the circuit board 40 is used to connect various battery cells on the one hand, and is also used to install corresponding circuit elements required by the battery on the other hand.

[0075] During actual use of the battery, the circuit board 40 generates a large amount of heat due to the passage of current and the operation of the installed circuit elements, and the heat conducting plate 2 can conduct the heat of the circuit board 40 to achieve cooling.

[0076] Furthermore, heat can be transferred between the circuit board 40 and the heat conducting plate 2 and between the battery cell and the heat conducting plate 2 through the heat conducting adhesive, thereby increasing the heat exchange rate and further improving the heat dissipation effect.

[0077] The injection mold of the utility model has an injection molding cavity, a profiling groove is provided in the injection molding cavity, the profiling groove is used to accommodate the heat conducting plate 2, a cover molding gap is defined between the heat conducting plate 2 and the inner wall of the injection molding cavity, and the cover molding gap is used to be filled with injection molding material to form a cover body 1.

[0078] It can be understood that the injection mold can be correspondingly assembled on the injection molding equipment in the prior art, and the injection molding rubber material is injected into the injection molding cavity of the injection mold through the injection molding equipment. The groove wall profile of the profiling groove is adapted to the heat conducting plate. After the heat conducting plate is placed in the profiling groove, the heat conducting plate will fully contact with each position of the inner wall surface of the profiling groove, thereby preventing the rubber material from being injected between the heat conducting plate and the profiling groove.

[0079] The cover molding gap between the inner wall of the injection molding cavity and the heat conducting plate will be filled with rubber, and this part of the rubber will contact the peripheral side wall a of the heat conducting plate 2. In this way, the cover body 1 will be directly formed on the peripheral side wall a after the rubber is cooled. Since the rubber is in direct contact with the peripheral side wall a, the contact position of the cover body 1 and the heat conducting plate 2 will maintain a very close fit, thereby ensuring the sealing to a certain extent.

[0080] In the description of the above embodiments, the up, down, left, and right orientation relationship refers to the orientation of the product when it is normally used, that is, the cover body 1 is located at the top and the base body 4 is located at the bottom. The top and bottom refer to the up and down position relationship when the product is properly placed or in normal use.

[0081] The implementation of this utility model has the following beneficial effects:

[0082] The utility model relates to a battery box, a battery and an injection mold, wherein the battery includes a battery box; on the battery box, on the one hand, a heat conducting plate is fixed to a mounting through hole by adopting a connecting structure, and the connecting structure can also play a role of sealing protection to a certain extent; on the other hand, a sealing layer is arranged in the sealing groove to improve the sealing between the heat conducting plate and the cover body, thereby further improving the sealing protection effect. In addition, due to the arrangement of the heat conducting plate, heat exchange can be performed on both sides of the cover body through the heat conducting plate, and in actual application, even if the battery box is completely closed, the heat conducting plate can still discharge the heat inside the battery box to the outside in time, thereby avoiding excessive temperature inside the battery box, and thus avoiding high temperature life attenuation of the battery cell. Therefore, the utility model can further avoid excessive temperature inside the battery box when the battery box is configured to be fully closed to improve the protection level.
