Description

Technical Field

[0001] This utility model relates to the field of battery pack technology, and in particular to a snap-fit ​​housing structure for battery packs. Background Technology

[0002] Batteries with high charge / discharge capacity density, such as lithium-ion batteries, are often not used alone. Instead, they are assembled into battery packs and housed together with their internal components in a casing made of materials such as synthetic resin. Subsequently, this integrated battery pack is installed in devices that require power.

[0003] Currently, the upper and lower housings used to secure battery packs are mainly installed using two methods: ultrasonic welding or screw fastening. However, these two methods are not only relatively expensive, but also quite cumbersome during installation. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, the present invention provides a snap-fit ​​housing structure for battery packs.

[0005] The technical solution is: a snap-fit ​​housing structure for a battery pack, including a lower cover, a battery pack, and an upper cover. The battery pack is disposed in the lower cover, and the upper cover is disposed on the top of the battery pack. The upper cover has two through holes spaced apart on its top. The structure also includes a snap-fit ​​assembly and a limiting assembly. The snap-fit ​​assembly is disposed between the upper cover and the lower cover, and the limiting assembly is disposed on the snap-fit ​​assembly. The snap-fit ​​assembly is used to stably connect the upper cover and the lower cover, and the limiting assembly is used to limit the snap-fit ​​assembly.

[0006] Furthermore, the buckle assembly includes a long plate, a short plate, and a locking plate. Buckle assemblies are provided between the front and rear sides of the upper and lower covers, and the two are arranged in an upside-down manner. Taking the front buckle assembly as an example, a long plate is fixedly connected to the front bottom of the upper cover, and a short plate is fixedly connected to the front top of the lower cover. Two locking plates are fixedly connected to the short plate at intervals, and two limiting openings that cooperate with the locking plates are opened at intervals on the long plate.

[0007] Furthermore, the limiting assembly includes a fixing seat, a plug plate, and a socket. The fixing seat is fixedly connected to the side walls of the long plate on the front side and the short plate on the rear side, which are far apart from each other. The plug plate is slidably arranged in both fixing seats. The socket is fixedly connected to the side walls of the short plate on the front side and the long plate on the rear side, which are far apart from each other. The lower part of the two plug plates can be inserted into the adjacent socket.

[0008] Furthermore, it also includes rubber blocks, which are embedded and fixedly connected to the lower sidewalls of the two insert plates that are far apart from each other.

[0009] Furthermore, it also includes anti-slip rings, with two anti-slip rings fixedly connected at intervals on the outer walls of both the upper and lower covers.

[0010] Furthermore, it also includes corner protectors, with corner protectors fixedly connected to the four corners of the bottom of the lower cover and the four corners of the top of the upper cover.

[0011] The beneficial effects of this utility model are as follows: by cooperating with the upper limit opening of the card plate and the long plate, a stable connection between the upper and lower covers of the battery pack is achieved, which not only reduces manufacturing costs but also greatly simplifies the installation process. In addition, by inserting the insert plate to fix the long plate, the problem of card plate loosening caused by deformation of the long plate is effectively prevented, further enhancing the stability of the connection. This not only improves the assembly efficiency of the battery pack but also ensures its stability and safety during use. Attached Figure Description

Detailed Implementation

[0017] The present invention will now be described more fully below with reference to the accompanying drawings, in which presently preferred embodiments of the invention are shown. However, the present invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided for thoroughness and completeness and to fully convey the scope of the invention to those skilled in the art.

[0018] Example: A snap-fit ​​housing structure for battery packs, such as Figures 1-4As shown, it includes a lower cover 1, a battery pack 2, and an upper cover 3. The lower cover 1 houses the battery pack 2, and the top of the battery pack 2 has positive and negative wires for connecting the batteries in the battery pack 2 in series or parallel. The top of the battery pack 2 has the upper cover 3, which has two through holes 4 at intervals for the positive and negative wires to pass through. It also includes a snap-fit ​​assembly and a limiting assembly. The snap-fit ​​assembly is provided between the upper cover 3 and the lower cover 1, and the limiting assembly is provided on the snap-fit ​​assembly. The snap-fit ​​assembly is used to stably connect the upper cover 3 and the lower cover 1, and the limiting assembly is used to limit the snap-fit ​​assembly.

[0019] like Figure 2 and Figure 3 As shown, the buckle assembly includes a long plate 51, a short plate 52, and a locking plate 53. Buckle assemblies are provided between the front and rear sides of the upper cover 3 and the lower cover 1, and the two are arranged in an upside-down manner. Taking the buckle assembly on the front side as an example, the long plate 51 is welded and fixed to the front bottom of the upper cover 3, and the short plate 52 is welded and fixed to the front top of the lower cover 1. Two locking plates 53 are welded and fixed at intervals on the short plate 52, and two limiting openings 54 that cooperate with the locking plates 53 are opened at intervals on the long plate 51.

[0020] like Figure 2 , Figure 3 and Figure 4 As shown, the limiting assembly includes a fixing base 61, a plug plate 62, and a socket 63. The fixing base 61 is welded and fixed to the side walls of the long plate 51 on the front side and the short plate 52 on the rear side, which are far apart from each other. The plug plate 62 is slidably disposed in both fixing bases 61. The socket 63 is welded and fixed to the side walls of the short plate 52 on the front side and the long plate 51 on the rear side, which are far apart from each other. The lower part of the two plug plates 62 can be inserted into the adjacent socket 63.

[0021] In use, the operator first places the battery pack 2 properly inside the lower cover 1. Then, a top cover 3 that matches the size of the lower cover 1 is selected, and the positive and negative wires of the battery pack 2 are passed through the two through holes 4 opened at the top of the top cover 3. Then, the top cover 3 is firmly placed on top of the battery pack 2 and gradually pressed down. As the top cover 3 continues to move down, the long plate 51 on the front side will also move down, so that the two locking plates 53 on the front side can be smoothly inserted into the pre-opened limiting openings 54 on the front long plate 51. At the same time, the two locking plates 53 on the rear side will also move down with the lower cover. The upper cover 3 and the lower cover 1 move downwards in cooperation with each other and finally snap into the corresponding limiting opening 54 on the rear long plate 51. In this way, the upper cover 3 and the lower cover 1 can achieve a stable connection. Compared with ultrasonic welding or screw tightening, this method not only greatly reduces costs but also greatly simplifies the installation process. After the snap plate 53 is successfully snapped into the limiting opening 54, the staff inserts the two insert plates 62 downwards into the adjacent sockets 63. The purpose of this step is to reduce the deformation that the long plate 51 may undergo in the front-back direction, thereby effectively preventing the snap plate 53 from becoming loose due to deformation.

[0022] It also includes rubber blocks 7, which are embedded and bonded to the lower sidewalls of the two insert plates 62 that are far apart from each other.

[0023] By setting the rubber block 7, the friction between the plug plate 62 and the socket 63 is further increased. Even when the upper cover 3 and the lower cover 1 are placed upside down, the plug plate 62 can be firmly kept in the socket 63 and will not easily come off.

[0024] It also includes anti-slip rings 8, with two anti-slip rings 8 being welded and fixed at intervals on the outer walls of the upper cover 3 and the lower cover 1.

[0025] By setting up anti-slip rings 8, when staff hold the upper cover 3 or the lower cover 1, the anti-slip rings 8 can increase the friction between them and their hands, thereby effectively avoiding the risk of falling.

[0026] It also includes corner protectors 9. Corner protectors 9 are welded and fixed at the four corners of the bottom of the lower cover 1, and corner protectors 9 are also fixedly connected at the four corners of the top of the upper cover 3.

[0027] By setting corner protectors 9, the four corners of the battery pack 2 are effectively protected against external impacts, thereby protecting the battery pack 2 from damage.

[0028] Those skilled in the art should understand that the above embodiments do not limit the present invention in any way, and all technical solutions obtained by means of equivalent substitution or equivalent transformation fall within the protection scope of the present invention.
