In this way, after the first support 1 and the second support 2 are assembled, the electrode posts of the batteries abut against the first welding piece 34, the bottom ends of the battery cases of the batteries abut against the second welding piece 42, and the batteries fixed in the first positioning area 3 on the first support 1 and the batteries fixed in the second positioning area 4 on the first support 1 can be connected in series through the connecting wire on the first support 1.
In combination with the above, after the first support 1 and the second support 2 are assembled, the first welding area and the second welding area are coplanar on one side of the first support 1, and therefore, the first welding piece 34 and the second welding piece 42 are coplanar, so that the first welding piece 34 and the electrode column are welded conveniently through a one-time penetration welding process on the first welding piece 34 and the second welding piece 42, the second welding piece 42 and the bottom end of the battery shell are welded, and the welding efficiency is improved.

Because the first welding area and the second welding area on the first bracket 1 are positioned on the same plane, two ends of the connecting wire are coplanar, so that the welding of the connecting wire with the electrode column and the bottom end of the battery shell is realized through a one-time penetration welding process at two ends of the connecting wire, and the welding efficiency is improved.
In the present embodiment, in order to ensure that the batteries fixed between the first bracket 1 and the second bracket 2 do not shift when the first bracket 1 and the second bracket 2 are assembled, in some embodiments, as shown in fig. 4 or fig. 5, the second positioning region 4 is formed with a second positioning cavity 41, and the second positioning cavity 41 is used for accommodating the bottom of the battery housing.
Therefore, 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, the heat dissipation of the batteries is facilitated, and the problems that the batteries are natural or explode due to the fact that the heat dissipation is not urgent are solved.
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 protrusions can be a prismatic cavity or a cylindrical cavity, and the like, as long as the bottom of the battery shell extends into the second positioning cavity 41, and the side wall of the battery shell can be abutted against the side wall of the second positioning cavity 41, so that the battery shell is not limited in the embodiment of the application.
The columnar bulge is of a columnar hollow structure, and a cavity formed by the columnar hollow structure forms a second positioning cavity 41; or the columnar protrusion is a columnar solid structure, and at this time, a plurality of columnar protrusions extend from the second positioning area 4 to the support close to the corresponding side, and are distributed along the circumferential direction to enclose the second positioning cavity 41.
In other embodiments, as shown in fig. 4 or fig. 5, the first positioning region 3 is formed with a first positioning cavity 32, the protrusion 31 is located in the first positioning cavity 32, and the first positioning cavity 32 is used for accommodating the top of the battery shell.
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, the heat dissipation of the batteries is facilitated, and the problems of nature or explosion and the like of the batteries due to the fact that the heat dissipation is not urgent are solved.
The structure of the first positioning cavity 32 is similar to that of the second positioning cavity 41, and reference may be made to the above description for details, which are not described in detail in this embodiment of the present application.
Illustratively, the first positioning cavity 32 is a cavity surrounded by a columnar protrusion extending from the first positioning area 3 to the bracket near the corresponding side, and the columnar protrusion is a columnar hollow structure, and a cavity surrounded by the columnar hollow forms the first positioning cavity 32.
Of course, in the embodiments of the present application, the battery may be limited 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 region 3 is used to abut against the top end of the battery case, and the protrusion 31 of the first positioning region 3 may be a block-shaped protrusion or an annular protrusion. Illustratively, as shown in fig. 4 or 5, the protrusion 31 of the first positioning region 3 has a ring shape.
Wherein, when the arch 31 of first locating area 3 is the annular, can increase the butt area to the top of battery case to improve the steadiness fixed to the battery.
In some embodiments, in combination with the above description of the first positioning region 3 having the first positioning cavity 32 and the protrusion 31 located in the first positioning cavity 32, when the protrusion 31 has a ring shape, as shown in fig. 6, an annular space is formed between the protrusion 31 and the cavity wall of the first positioning cavity 32, and the annular space contains the adhesive.
In this way, when the top end of the battery case abuts on the projection 31, the region of the top end face of the battery case located outside the annular projection can be bonded to the corresponding bracket by the adhesive, thereby further ensuring the stability of the battery fixation.
The adhesive may be a structural adhesive, a double-sided adhesive, or the like. The adhesive has a certain fluidity so that after the annular space is filled with the adhesive, when the battery is in the first positioning cavity 32, the redundant adhesive can be extruded out of the annular space, thereby avoiding the adhesive from interfering with the butting of the protrusion 31 and the top end of the battery shell.
Optionally, the protrusion 31 is in the shape of a triangular ring. Thus, while satisfying the abutment on the top end of the battery case, the annular space can be made larger with the side wall of the first positioning cavity 32 in the wall surrounding area, so that after the adhesive is filled in the annular space, the bonding area on the top end of the battery case can be increased, and the stability of battery fixation can be further improved.
In some embodiments, as shown in fig. 7 and 8, the side of the protrusion 31 facing away from the center of the first positioning region 3 has a rib 33, and the rib 33 is lower than the supporting surface 311 of the protrusion 31 facing away from the first positioning region 3, or is flush with the supporting surface 311 of the protrusion 31 facing away from the first positioning region 3.
In this way, the reinforcing rib 33 is arranged on one side of the bulge 31 far away from the center of the first positioning area 3, so that the strength of the bulge 31 is ensured, and the situation that the bulge 31 is damaged and deformed is avoided; the ribs 33 provided at the same time do 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 region 3 is parallel to the first positioning region 3, and the surface of the reinforcing rib 33 facing away from the first positioning region 3 is flush with the supporting surface 311 of the protrusion 31 facing away from the first positioning region 3, or lower than the supporting surface 311 of the protrusion 31 facing away from the first positioning region 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 departing from the first positioning region 3 at the joint with the protrusion 31 may form a chamfer structure facing away from the first positioning region 3 and recessed, at this time, in order to avoid the chamfer structure protruding out of the supporting surface 311 of the protrusion 31 departing from the first positioning region 3, so as to interfere the abutment of the protrusion 31 and the top end of the battery case, the surface of the reinforcing rib 33 departing from the first positioning region 3 may be slightly lower than the supporting surface 311 of the protrusion 31 departing from the first positioning region 3.
Alternatively, the dimension of the reinforcing ribs 33 in the direction perpendicular to the first positioning region 3 is gradually decreased in the direction away from the projection 31. That is, the surface of the reinforcing rib 33 departing from the first positioning area 3 is an inclined surface forming a certain included angle with the first bracket 1. Thus, the material consumption of the reinforcing ribs 33 can be reduced, and the supporting strength of the protrusions 31 can be ensured.
Alternatively, in combination with the above explanation that the protrusion 31 is annular, one side of the protrusion 31 away from the center of the first positioning region 3 has a plurality of ribs 33, and the plurality of ribs 33 are uniformly distributed along the circumferential direction. In this way, the plurality of reinforcing ribs 33 distributed uniformly improve the overall support strength of the annular projection 31.
The embodiment of the application also provides a battery pack. The battery pack comprises a plurality of batteries and the battery support 10 in the above embodiment, the plurality of batteries are fixed between the first support 1 and the second support 2, the bottom end of a battery shell of one battery abuts against the second positioning area 4, and the top end of the battery shell abuts against the corresponding protrusion 31 of the second positioning area 4.
In this way, in combination with the battery holder 10, since the first welding area and the second welding area on one side of the first holder 1 and the first welding area and the second welding area on one side of the second holder 2 are located on the same plane, when welding operation is performed, welding of the first welding area and the second welding area can be completed through one-time welding process, so that welding efficiency is improved, assembly efficiency of a battery pack is improved, and assembly quality of the battery pack is improved.
The embodiment of the application also provides electric equipment which can be energy storage equipment, a vehicle and the like. The electric equipment comprises the battery pack according to the above embodiment. Therefore, by combining the battery pack, under the condition of higher assembly efficiency and assembly yield, the use cost of the electric equipment using the battery pack can be effectively reduced, and the service life is prolonged.
