In the related art, the battery support comprises a first support and a second support, wherein the first support is provided with a plurality of first positioning areas arranged at intervals, the second support is provided with a plurality of second positioning areas arranged at intervals, the plurality of first positioning areas are in one-to-one correspondence with the plurality of second positioning areas, and the corresponding first positioning areas are opposite to the second positioning areas.
The first positioning area and the second positioning area are respectively provided with a welding hole, so that the first positioning area is abutted against the top end of the battery shell, the electrode column of the battery is exposed at the welding hole, the second positioning area is abutted against the bottom end of the battery shell, and the to-be-welded area of the bottom end surface of the battery shell is exposed at the welding hole.
The applicant found that, when the battery is assembled in the above manner, in order to realize the series connection of the battery, there are both the top end and the bottom end of the battery case at one side of the first bracket, and the electrode post of the battery is caused to be out of the same plane with the bottom end of the battery case at one side of the first bracket (the electrode post protrudes out of the top end of the battery case), so that the first welding area (the welding section of the electrode post) and the second welding area (the area to be welded at the bottom end of the battery case) at one side of the first bracket are not in the same plane. As such, when the electrical connection of the plurality of batteries is completed, two welding processes are required, thereby reducing welding efficiency.
Embodiments of the present application provide a battery holder 10. As shown in fig. 1 and 2, the battery holder 10 includes: the first support 1 and the second support 2 are oppositely arranged, the first support 1 faces one side of the second support 2, and at least one first positioning area 3 and at least one second positioning area 4 are arranged on one side of the second support 2 facing the first support 1.
The first positioning areas 3 of the first bracket 1 are in one-to-one correspondence with the second positioning areas 4 of the second bracket 2, the second positioning areas 4 of the first bracket 1 are in one-to-one correspondence with the first positioning areas 3 of the second bracket 2, and the corresponding first positioning areas 3 are opposite to the second positioning areas 4. In this way, a battery can be limited between the corresponding first positioning zone 3 and second positioning zone 4 when the battery to be fixed is assembled by means of the battery holder 10.
And when realizing spacing to the battery, one side of first support 1, one side between the second all has first welded zone (the welding terminal surface of electrode post) and second welded zone (the waiting welded zone of battery housing's bottom), in order to guarantee first welded zone and the second welded zone of one side of first support 1 to and first welded zone and the second welded zone of one side of second support 2 all lie in the coplanar, as shown in fig. 3 and fig. 4, first location area 3 has protruding 31, protruding 31 is used for the top of butt battery housing, and protruding 31 corresponding second location area 4 is used for the bottom of butt battery housing.
Wherein the height of the protrusions 31 is equal to the height of the electrode posts of the battery protruding from the top end of the battery case. In this way, through the arrangement of the protrusions 31 in the first positioning area 3, the distance between the outer side face of the first support 1 and the outer side face of the second support 2 can be limited, and then when a plurality of batteries are limited through the first support 1 and the second support 2, the first welding area and the second welding area on one side of the first support 1 and the first welding area and the second welding area on one side of the second support 2 are all located on the same plane, so that when welding operation is performed, welding of the first welding area and the second welding area can be completed through one welding process, and welding efficiency is improved.
In the embodiment of the application, when a plurality of batteries are fixed through the first bracket 1 and the second bracket 2, in order to ensure that the first positioning area 3 on the first bracket 1 is opposite to the corresponding second positioning area 4 on the second bracket 2 and the second positioning area 4 on the first bracket 1 is opposite to the corresponding first positioning area 3 on the second bracket, optionally, a foolproof protrusion 31 is arranged on the first bracket 1, and a foolproof groove is arranged on the second bracket 2. Thus, on assembling the first bracket 1 and the second bracket 2, the fool-proof protrusion 31 on the first bracket 1 extends into the fool-proof groove on the second bracket 2.
The first bracket 1 and the second bracket may be detachably connected by a buckle, or may be detachably connected by a fixing bolt, etc., which is not limited in the embodiment of the present application.
In some embodiments, as shown in fig. 5, the first positioning area 3 has a first welding tab 34, the second positioning area 4 has a second welding tab 42, and the first bracket 1 and the second bracket 2 are both provided with at least one connecting wire, and two ends of the connecting wire are respectively connected with the first welding tab 34 and the second welding tab 42 on the same bracket.
In this way, after the first bracket 1 and the second bracket 2 are assembled, the electrode column of the battery is abutted against the first welding tab 34, the bottom end of the battery shell of the battery is abutted against the second welding tab 42, and the series connection of the battery fixed on the first positioning area 3 on the first bracket 1 and the battery fixed on the second positioning area 4 on the first bracket 1 can be realized through the connecting wire on the first bracket 1.
Wherein, in combination with the above, after the first bracket 1 and the second bracket 2 are assembled, the first welding area and the second welding area are coplanar at one side of the first bracket 1, and therefore, the first welding tab 34 and the second welding tab 42 are coplanar, so that the welding of the first welding tab 34 and the electrode column is conveniently realized on the first welding tab 34 and the second welding tab 42 through a one-time penetration welding process, and the welding of the second welding tab 42 and the bottom end of the battery shell is realized, thereby improving the welding efficiency.
In other embodiments, as shown in fig. 4, the first positioning area 3 and the second positioning area 4 each have a welding hole 5.
The welding holes 5 of the first positioning area 3 are used for exposing electrode columns of the battery, and the welding holes 5 of the second positioning area 4 are used for exposing areas to be welded at the bottom end of the battery shell. So, after first support 1 and second support 2 accomplish the assembly, can all set up the connecting wire in first support 1 one side that deviates from second support 2 to and in second support 2 one side that deviates from first support 1 to realize the series-parallel connection of a plurality of batteries between first support 1 and the second support 2.
For two batteries connected in series, taking the first bracket 1 as an example, one end of a connecting wire on the first bracket 1 extends to a welding hole 5 of the first positioning area 3 and covers an electrode column of the battery, and the other end of the connecting wire on the first bracket 1 extends to a welding hole 5 of the second positioning area 4 and covers a to-be-welded area at the bottom end of the battery shell. Because the first welding area and the second welding area on the first bracket 1 are positioned on the same plane, the two ends of the connecting wire are coplanar, so that the welding of the connecting wire, the electrode column and the bottom end of the battery shell is realized through a one-time penetration welding process at the two ends of the connecting wire, and the welding efficiency is improved.
In the embodiment of the present application, in order to ensure that the battery fixed between the first bracket 1 and the second bracket 2 is not displaced when the first bracket 1 and the second bracket 2 are assembled, in some embodiments, as shown in fig. 4 or 5, the second positioning area 4 is formed with a second positioning cavity 41, and the second positioning cavity 41 is used to accommodate the bottom of the battery case.
Thus, the stability of the battery is ensured by limiting the bottom of the battery shell through the second positioning cavity 41. Meanwhile, due to the limitation of the wall thickness of the second positioning cavity 41, a certain gap exists between two adjacent batteries, so that a heat dissipation channel can be formed around the batteries, heat dissipation of a plurality of batteries is facilitated, and the problems of nature or explosion of the batteries due to the fact that the heat dissipation is not urgent are avoided.
The second positioning cavity 41 is a cavity surrounded by columnar protrusions extending from the second positioning area 4 to the bracket near the corresponding side. The second positioning cavity 41 surrounded by the columnar protrusion may be a prismatic cavity, or may be a cylindrical cavity, so long as the bottom of the battery case extends into the second positioning cavity 41, and the side wall of the battery case can abut against the side wall of the second positioning cavity 41, which is not limited in the embodiment of the present application.
Wherein, the columnar bulge is a columnar hollow structure, and a cavity surrounded by the columnar hollow forms a second positioning cavity 41; or the columnar protrusions are of a columnar solid structure, and a plurality of columnar protrusions extend towards the bracket near the corresponding side of the second positioning area 4, and the columnar protrusions are distributed along the circumferential direction so as to enclose a second positioning cavity 41.
In other embodiments, as shown in fig. 4 or 5, the first positioning area 3 is formed with a first positioning cavity 32, and the protrusion 31 is located in the first positioning cavity 32, and the first positioning cavity 32 is used to accommodate the top of the battery case.
Thus, the stability of the battery is ensured by limiting the top of the battery shell through the first positioning cavity 32. Meanwhile, due to the limitation of the wall thickness of the first positioning cavity 32, a certain gap exists between two adjacent batteries, so that a heat dissipation channel can be formed around the batteries, heat dissipation of a plurality of batteries is facilitated, and the problems of nature or explosion of the batteries due to the fact that the heat dissipation is not urgent are avoided.
The structure of the first positioning cavity 32 is similar to that of the second positioning cavity 41 described above, and reference is specifically made to the above description, which is not repeated in the embodiment of the present application.
The first positioning cavity 32 is exemplified by a cavity surrounded by columnar projections extending toward the bracket near the corresponding side in the first positioning area 3, and the columnar projections are a columnar hollow structure, and the cavity surrounded by the columnar hollows forms the first positioning cavity 32.
Of course, in the embodiment of the present application, the limit of the battery may be achieved by combining the two embodiments. That is, as shown in fig. 4 or 5, the first positioning area 3 is formed with a first positioning cavity 32, and the second positioning area 4 is formed with a second positioning cavity 41.
In the embodiment of the present application, the protrusion 31 of the first positioning area 3 is used to abut against the top end of the battery case, and the protrusion 31 of the first positioning area 3 may be a block-shaped protrusion or an annular protrusion. As shown in fig. 4 or 5, the projection 31 of the first positioning area 3 is ring-shaped, for example.
Wherein, when the protruding 31 of first location district 3 is annular, can increase the area of abutment to the top of battery case to improve the steadiness to battery fixation.
In some embodiments, in combination with the description that the first positioning area 3 has the first positioning cavity 32 and the protrusion 31 is located in the first positioning cavity 32, when the protrusion 31 is in a ring shape, as shown in fig. 6, an annular space is formed between the protrusion 31 and a cavity wall of the first positioning cavity 32, and an adhesive is contained in the annular space.
In this way, by filling the adhesive in the annular space, when the top end of the battery case abuts against the protrusion 31, the region of the top end surface of the battery case outside the annular protrusion can be adhered to the corresponding bracket by the adhesive, thereby further ensuring the stability of battery fixation.
The adhesive can be structural adhesive, double-sided adhesive or the like. The adhesive has a certain fluidity so that when the battery is in the first positioning cavity 32 after the adhesive is filled in the annular space, the excessive adhesive can be extruded out of the annular space, thereby avoiding the adhesive from interfering with the abutting of the protrusion 31 and the top end of the battery case.
Alternatively, the protrusion 31 has a triangular ring shape. In this way, the annular space larger than the side wall surrounding area of the first positioning chamber 32 can be formed while the contact with the top end of the battery case is satisfied, so that the adhesive area of the top end of the battery case can be increased after the annular space is filled with the adhesive, thereby further improving the stability of the battery fixation.
In some embodiments, as shown in fig. 7 and 8, the side of the protrusion 31 away from the center of the first positioning area 3 has a reinforcing rib 33, and the reinforcing rib 33 is lower than the supporting surface 311 of the protrusion 31 facing away from the first positioning area 3 or is flush with the supporting surface 311 of the protrusion 31 facing away from the first positioning area 3.
In this way, the reinforcing rib 33 is arranged on one side of the protrusion 31 far from the center of the first positioning area 3, so that the strength of the protrusion 31 is ensured, and the damage and deformation of the protrusion 31 are avoided; the reinforcing rib 33 provided at the same time does not interfere with the abutment of the projection 31 with the top end of the battery case.
Optionally, the surface of the reinforcing rib 33 facing away from the first positioning area 3 is parallel to the first positioning area 3, and at this time, the surface of the reinforcing rib 33 facing away from the first positioning area 3 is flush with the supporting surface 311 of the protrusion 31 facing away from the first positioning area 3, or is lower than the supporting surface 311 of the protrusion 31 facing away from the first positioning area 3.
It should be noted that, in the manufacturing process of the first bracket 1 and the second bracket 2, in order to facilitate demolding, the surface of the reinforcing rib 33 facing away from the first positioning area 3 may form a chamfer structure facing away from the first positioning area 3 at the joint with the protrusion 31, and the chamfer structure is concave, so that the protrusion 31 of the chamfer structure is prevented from facing away from the supporting surface 311 of the first positioning area 3, and thus the surface of the reinforcing rib 33 facing away from the first positioning area 3 may be slightly lower than the supporting surface 311 of the protrusion 31 facing away from the first positioning area 3, so as to avoid the contact between the protrusion 31 and the top end of the battery case.
Alternatively, the dimension of the reinforcing ribs 33 in the direction perpendicular to the first positioning area 3 gradually decreases in the direction away from the projections 31. I.e. the surface of the reinforcing rib 33 facing away from the first positioning area 3 is an inclined surface forming an angle with the first bracket 1. In this way, the strength of the support for the protrusion 31 can be ensured while reducing the amount of the reinforcing rib 33.
Alternatively, in combination with the above explanation of the protrusion 31 having a ring shape, the side of the protrusion 31 away from the center of the first positioning area 3 has a plurality of reinforcing ribs 33, and the plurality of reinforcing ribs 33 are uniformly distributed in the circumferential direction. In this way, the strength of the overall support for the annular projection 31 is improved by the plurality of reinforcing ribs 33 which are uniformly distributed.
The embodiment of the application also provides a battery pack. The battery pack includes a plurality of batteries and the battery support 10 according to the above embodiment, the plurality of batteries are fixed between the first support 1 and the second support 2, the bottom end of the battery housing of a battery is abutted to the second positioning area 4, and the top end of the battery housing is abutted to the protrusion 31 corresponding to the second positioning area 4.
Thus, in combination with the above-mentioned battery support 10, because the first welding area and the second welding area on one side of the first support 1 and the first welding area and the second welding area on one side of the second support 2 are all located on the same plane, when the welding operation is performed, the welding of the first welding area and the second welding area can be completed through one welding process, so that the welding efficiency is improved, the assembly efficiency of the battery pack is further improved, and meanwhile, the assembly quality of the battery pack is improved.
The embodiment of the application also provides electric equipment which can be energy storage equipment, vehicles and the like. The electric equipment comprises the battery pack. Therefore, by combining the battery pack, under the conditions of higher assembly efficiency and assembly yield, the use cost of the electric equipment can be effectively reduced for the electric equipment using the battery pack, and the service life of the electric equipment is prolonged.
