Description

Technical Field

[0001] This utility model relates to the field of aluminum shell structure technology, specifically a double-through aluminum shell tenon and mortise structure. Background Technology

[0002] Battery cells are the most basic components of modules and battery packs. A module is made up of one or more battery cells connected in series or parallel, and usually includes a protective circuit board, connectors and insulating materials, etc.

[0003] The modules can be modified to add or remove cells as needed to meet the requirements of different usage scenarios, while the battery pack is composed of multiple modules connected in a certain way to form a whole;

[0004] The dual-channel aluminum shell structure is designed to accommodate and protect the internal battery cells or other components. Lithium batteries are used in existing mobile phones and other electronic products, and they are protected by a dual-channel aluminum shell. However, most existing dual-channel aluminum shells use welding to connect the upper and lower aluminum shells. Welding is a non-removable connection. Therefore, when a single aluminum shell is deformed or damaged, both the upper and lower aluminum shells need to be replaced together. At this time, the intact aluminum shells that have not been deformed or impacted will also be scrapped, which greatly reduces the actual utilization efficiency of the structure, results in a certain amount of material waste, and increases maintenance and repair costs, making it impractical. Utility Model Content

[0005] The purpose of this utility model is to provide a double-through aluminum shell tenon and mortise structure to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a double-through aluminum shell tenon and mortise structure, comprising an upper aluminum shell and a lower aluminum shell, wherein the upper aluminum shell and the lower aluminum shell have the same surface area, and lower tenon blocks are fixedly installed on both sides of the lower surface of the upper aluminum shell, and tenon block holes are opened on the side of the lower tenon blocks. Lower tenon plates are fixedly installed at the center of the lower surface of both ends of the upper aluminum shell, and two symmetrically distributed tenon plate holes are opened on the lower tenon plates. Lower mortise grooves adapted to the lower tenon blocks are opened on both sides of the upper surface of the lower aluminum shell, and side through holes are opened at the bottom side of the lower mortise grooves. A plug with a diameter adapted to the hole is provided in the side through hole, and a magnetic ring is fixedly installed on the outside of the side through hole. A magnetic sheet is fixedly installed at the tail end of the plug. Strip mortise grooves adapted to the lower tenon plates are opened on the upper surface of both ends of the lower aluminum shell.

[0007] Preferably, the side of the strip mortise is provided with a mating hole that matches the tenon hole, and both the mating hole and the tenon hole are threaded holes.

[0008] Preferably, the outer side of the mating hole is provided with a threaded pin that matches the hole diameter.

[0009] Preferably, a cross groove is formed on the outer surface of one end of the screw pin.

[0010] Preferably, the lower aluminum shell is provided with a number of films on its side, and the number of films is the same as the number of side through holes.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This utility model features a double-through aluminum shell tenon and mortise structure, which allows for extremely convenient tenon and mortise connection between the upper and lower aluminum shells. This facilitates rapid assembly of the upper and lower aluminum shells. The upper and lower aluminum shells are designed with a tenon and mortise-and-mortise separation structure. Therefore, when one shell is deformed by external impact, only the deformed shell needs to be removed and replaced with a new shell of the same type. There is no need to replace the entire aluminum shell assembly. Compared to traditional welded integrated structures, this utility model's tenon and mortise connection separation structure allows for targeted shell replacement, effectively improving the utilization efficiency of the other shell, avoiding the waste of structural materials from uniform removal, effectively reducing actual maintenance and repair costs, lowering later usage costs, and offering better practicality.

[0022] Please see Figure 1-5 The present invention provides an embodiment of a double-through aluminum shell tenon structure, comprising an upper aluminum shell 1 and a lower aluminum shell 6, wherein, in order to make the vertical and horizontal planes of the upper aluminum shell 1 and the lower aluminum shell 6 coincide after being connected, the surface areas of the upper aluminum shell 1 and the lower aluminum shell 6 are the same.

[0023] Both sides of the lower surface of the upper aluminum shell 1 are fixedly installed with lower tenon blocks 4. The lower tenon blocks 4 have tenon holes 5 on their sides. The lower tenon plates 2 are fixedly installed at the center of the lower surface of the front and rear ends of the upper aluminum shell 1. The lower tenon plates 2 have two symmetrically distributed tenon holes 3 to facilitate connection with the structure of the lower aluminum shell 6.

[0024] The upper surface of the lower aluminum shell 6 is provided with lower mortise grooves 7 on both sides that are adapted to the lower tenon block 4. A side through hole 8 is provided at the bottom side of the lower mortise groove 7. A plug 10 with a diameter adapted to the hole is provided in the side through hole 8. A magnetic ring 9 is fixedly installed on the outside of the side through hole 8. A magnetic sheet 11 is fixedly installed at the tail end of the plug 10.

[0025] In this structural design, when it is necessary to connect the upper aluminum shell 1 and the lower aluminum shell 6 with a tenon and tenon, several lower tenons 4 of the upper aluminum shell 1 can be aligned with the lower mortise 7 of the lower aluminum shell 6. After alignment, the upper aluminum shell 1 can be manually pressed to insert several lower tenons 4 of the upper aluminum shell 1 into the lower mortise 7. In this way, through the cooperation of the lower tenons 4 and the lower mortise 7, the initial positioning connection between the upper aluminum shell 1 and the lower aluminum shell 6 can be completed, and the tenon and tenon positioning between the upper aluminum shell 1 and the lower aluminum shell 6 can be completed.

[0026] After the lower tenon 4 is fully inserted into the lower mortise 7, the tenon hole 5 of the lower tenon 4 can be horizontally aligned with the side through hole 8 of the lower mortise 7. At this time, a plug 10 can be inserted into the tenon hole 5 and the side through hole 8. The plug 10 can be used to make an insertion-type positioning connection between the lower tenon 4 and the mortise 7. In actual use, the inserted plug 10 can effectively prevent the lower tenon 4 from coming out of the lower mortise 7, thereby effectively preventing the upper aluminum shell 1 and the lower aluminum shell 6 from separating from each other. It has a good tenon and mortise structure positioning effect, increases the connection stability between the two shells, and improves the use effect.

[0027] Meanwhile, since a magnetic ring 9 is provided on the outside of the side through hole 8, the magnetic sheet 11 of the plug 10 can magnetically attract each other with the magnetic ring 9 during the insertion of the plug 10. In actual use, this structure can effectively prevent the plug 10 from falling out of the hole through the fixing effect of magnetic attraction, and has a good magnetic connection effect, increasing the structural stability of the plug 10.

[0028] Furthermore, strip-shaped mortises 13 adapted to the lower tenon plate 2 are provided on the upper surfaces of both the front and rear ends of the lower aluminum shell 6.

[0029] The strip-shaped mortise 13 has a mating hole 14 on its side that matches the tenon hole 3. Both the mating hole 14 and the tenon hole 3 are threaded holes. For the convenience of installing a columnar structure for fixed connection in the above two holes, please refer to the appendix of the instruction manual. Figure 1 as well as Figure 5 As shown, a threaded pin 15 adapted to the diameter of the hole 14 is provided on the outside of the hole 14, and a cross groove 16 is provided on the outer surface of one end of the threaded pin 15.

[0030] According to the above description, when the tenon blocks 4 of the upper aluminum shell 1 are aligned with the mortise 7 of the lower aluminum shell 6, the tenon plate 2 below the upper aluminum shell 1 can be aligned with the strip mortise 13 simultaneously. During the tenon-mortise connection between the tenon blocks 4 of the upper aluminum shell 1 and the mortise 7 of the lower aluminum shell 6, the tenon plate 2 below it can be inserted into the corresponding strip mortise 13 simultaneously.

[0031] After the lower tenon plate 2 is fully inserted into the strip mortise 13, the tenon plate hole 3 can be horizontally aligned with the mating hole 14. After the tenon plate hole 3 and the mating hole 14 are aligned, the screw pin 15 can be screwed into the two through a screwdriver. In this way, the screw pin 15 completes the threaded connection between the lower tenon plate 2 and the strip mortise 13. In actual use, the use of the screw pin 15 can further improve the connection strength between the upper aluminum shell 1 and the lower aluminum shell 6, and prevent the plug 10 from falling off due to external impact, which would cause the upper aluminum shell 1 and the lower aluminum shell 6 to separate. It can provide the final connection reinforcement for the shell structure of the tenon and mortise connection, and greatly improve the stability of the connection.

[0032] Furthermore, after the screw pin 15 of this utility model is fully screwed in, it can be directly placed inside the hole, as detailed in the attached instruction manual. Figure 4 As shown, there are no extra structural protrusions during actual use, which increases the hidden connection effect of the shell and reduces the space occupation effect.

[0033] In this embodiment, to improve the side-mounted anti-detachment effect of the plunger 10, a number of films 12 are provided on the side of the lower aluminum shell 6. The number of films 12 is the same as the number of side through holes 8. In actual use, the films 12 can be attached to the outer aluminum shell of the plunger 10, as detailed in the attached instruction manual. Figure 4 As shown, the film 12 can be used to prevent the plug 10 from falling off due to external impact, thereby improving the insertion stability of the plug 10.

[0034] Working principle: When it is necessary to connect the upper aluminum shell 1 and the lower aluminum shell 6 with a tenon and tenon, several lower tenons 4 of the upper aluminum shell 1 can be aligned with the lower mortise 7 of the lower aluminum shell 6. After alignment, the upper aluminum shell 1 can be manually pressed to insert several lower tenons 4 of the upper aluminum shell 1 into the lower mortise 7. In this way, through the cooperation of the lower tenons 4 and the lower mortise 7, the initial positioning connection between the upper aluminum shell 1 and the lower aluminum shell 6 can be completed, and the tenon and tenon positioning between the upper aluminum shell 1 and the lower aluminum shell 6 can be completed.

[0035] After the lower tenon 4 is fully inserted into the lower mortise 7, the tenon hole 5 of the lower tenon 4 can be horizontally aligned with the side through hole 8 of the lower mortise 7. At this time, a plug 10 can be inserted into the tenon hole 5 and the side through hole 8. The plug 10 can be used to make an insertion-type positioning connection between the lower tenon 4 and the mortise 7. In actual use, the inserted plug 10 can effectively prevent the lower tenon 4 from coming out of the lower mortise 7, thereby effectively preventing the upper aluminum shell 1 and the lower aluminum shell 6 from separating from each other. It has a good tenon and mortise structure positioning effect, increases the connection stability between the two shells, and improves the use effect.

[0036] Meanwhile, since a magnetic ring 9 is provided on the outside of the side through hole 8, the magnetic sheet 11 of the plug 10 can magnetically attract the magnetic ring 9 during the insertion process. In actual use, this structure effectively prevents the plug 10 from falling out of the hole through magnetic attraction, providing a good magnetic connection effect and increasing the structural stability of the plug 10. Additionally, the adhesive sheet 12 of this invention can be attached to the outer aluminum shell of the plug 10, as detailed in the attached instruction manual. Figure 4 As shown, the film 12 can be used to prevent the plug 10 from falling off due to external impact, thereby improving the insertion stability of the plug 10.

[0037] When the tenon blocks 4 of the upper aluminum shell 1 are aligned with the mortise 7 of the lower aluminum shell 6, the tenon plate 2 below the upper aluminum shell 1 can be aligned with the strip mortise 13 simultaneously. During the tenon-mortise connection between the tenon blocks 4 of the upper aluminum shell 1 and the mortise 7 of the lower aluminum shell 6, the tenon plate 2 below it can be inserted into the corresponding strip mortise 13 simultaneously.

[0038] After the lower tenon plate 2 is fully inserted into the strip mortise 13, the tenon plate hole 3 can be horizontally aligned with the mating hole 14. After the tenon plate hole 3 and the mating hole 14 are aligned, the screw pin 15 can be screwed into the two through a screwdriver. In this way, the screw pin 15 completes the threaded connection between the lower tenon plate 2 and the strip mortise 13. In actual use, the use of the screw pin 15 can further improve the connection strength between the upper aluminum shell 1 and the lower aluminum shell 6, and prevent the plug 10 from falling off due to external impact, which would cause the upper aluminum shell 1 and the lower aluminum shell 6 to separate. It can provide the final connection reinforcement for the shell structure of the tenon and mortise connection, and greatly improve the stability of the connection.

[0039] Furthermore, after the screw pin 15 of this utility model is fully screwed in, it can be directly placed inside the hole, as detailed in the attached instruction manual. Figure 4 As shown, there are no extra structural protrusions during actual use, which increases the hidden connection effect of the shell and reduces the space occupation effect;

[0040] When separation is required, simply tear off the film 12, then remove several plugs 10, unscrew several screws 15, and manually pry the two aluminum shells apart to complete the separation between the upper aluminum shell 1 and the lower aluminum shell 6.

[0041] Based on the above description, the double-through aluminum shell tenon and mortise structure of this utility model can extremely easily complete the tenon and mortise connection between the upper aluminum shell 1 and the lower aluminum shell 6, facilitating rapid assembly of the upper aluminum shell 1 and the lower aluminum shell 6. The upper aluminum shell 1 and the lower aluminum shell 6 are designed with a tenon and mortise-and-mortise separation structure. Therefore, when a shell is deformed by external impact, only the deformed aluminum shell needs to be removed and replaced with a brand new aluminum shell of the same type. There is no need to replace the entire aluminum shell assembly. Compared with the traditional welded integrated structure, the tenon and mortise connection separation structure of this utility model allows for targeted shell replacement, thereby effectively improving the actual utilization efficiency of the other shell, avoiding the waste of structural materials due to uniform removal, effectively reducing actual maintenance and repair costs, reducing later use costs, and improving practicality.

[0042] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
