Description

Technical Field

[0001] This utility model relates to the field of battery box manufacturing and processing technology, and in particular to a device for opening heat dissipation holes in a battery box. Background Technology

[0002] A battery compartment is a container used to hold and protect batteries. It can be a standalone unit or an integral part of a device. Its main functions are to secure the batteries, preventing them from shifting inside the device, and to provide insulation to prevent accidental short circuits between the positive and negative terminals. Additionally, the battery compartment provides an interface for the electrical connection between the battery and the device, facilitating the transfer of current.

[0003] A tooling for opening holes in a battery box cover is disclosed in Chinese utility model patent with publication number CN218018794U. Although the above-mentioned prior art greatly improves the accuracy of opening holes in the battery box cover, the materials used for battery boxes vary depending on their purpose, and most are made of plastic. When opening holes in plastic battery boxes, since the plastic battery box is hollow and has no internal support, drilling the outer wall will squeeze the battery box. Thus, when the feed speed is too fast or the drilling pressure is too high, stress concentration will occur in the plastic battery box, leading to cracking. This is especially true for some thin-walled plastic battery boxes, which are more susceptible to this effect. Therefore, it is necessary to design an opening device that can reduce the tendency of battery box openings to crack. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a battery box heat dissipation hole opening device.

[0005] This utility model is achieved by the following technical solution: a battery box heat dissipation hole opening device, including a drilling machine, a drilling table installed in the middle of the drilling machine, an auxiliary component that can position and support the battery box on the top side of the drilling table, an adjustment component that drives the auxiliary component to adjust its position at the bottom of the auxiliary component, a sliding groove opened on the top of the drilling table, and the auxiliary component including a support box set on the top side of the drilling table and two sliding blocks that are slidably set inside the sliding groove.

[0006] With the above technical solution, when making a hole in the battery box, the auxiliary component will support the battery box from inside, and the adjustment component will adjust the position of the auxiliary component so that the auxiliary component is located in the center of the hole. In this way, when supporting the battery box, it can also play a role in positioning the battery box during the hole making. This setting can reduce the problem of cracking when making a hole in the battery box, and can also play a role in positioning during the hole making.

[0007] As a further improvement to the above solution, the support box has an opening facing downwards, a positioning hole is provided on the top side of the support box, and the tops of the two sliding blocks extend upwards into the interior of the support box.

[0008] With the above technical solution, two sliding blocks are used to hold the support box in place inside, which fixes the position of the support box and facilitates positioning when making holes.

[0009] As a further improvement to the above solution, each of the two sliding blocks has a plug-in groove on its top, a limit block is fixedly installed inside each of the two plug-in grooves, a limit strip is provided on the opposite side of each of the two sliding blocks, a connecting block is fixedly installed on the side of each of the two limit strips near the adjacent sliding block, one side of each of the two connecting blocks extends into the interior of the adjacent plug-in groove, and a plug-in interface adapted to the limit block is provided at the bottom of each of the two connecting blocks, and each of the two connecting blocks is plugged into the adjacent sliding block through the adjacent limit block.

[0010] With the above technical solution, the limiting strip and the connecting block are inserted into the insertion slot of the sliding block, so that the positions of the two limiting strips are fixed and the position of the support box that abuts against them is fixed, thereby preventing the support box from shifting.

[0011] As a further improvement to the above solution, the adjustment assembly includes a bidirectional threaded rod disposed inside the sliding groove, both ends of which pass through the drilling table and extend to the outside of which a rotating block is fixedly installed.

[0012] Using the above technical solution, rotating the two rotating blocks will cause the bidirectional threaded rod to rotate.

[0013] As a further improvement to the above solution, both sliding blocks are threaded onto a bidirectional threaded rod.

[0014] Using the above technical solution, the rotation of the bidirectional threaded rod will cause the two sliding blocks to move closer to or further apart.

[0015] As a further improvement to the above solution, each of the rotating blocks has a fixing plate fixedly installed on both sides with a drilling table, and a friction block is provided on one side of each of the fixing plates. Each friction block has a plurality of push rods fixedly installed on the side away from the rotating block. One end of each push rod passes through the adjacent fixing plate and is fixedly installed with a limiting block. Each push rod is fitted with a push spring, and both ends of each push spring abut against the adjacent fixing plate and the friction block, respectively.

[0016] With the above technical solution, after the rotating block is manually rotated by the staff, it will fit into the friction block. In this way, under the restriction of the friction block, the rotating block cannot rotate automatically due to vibration.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] This invention, by setting up an auxiliary component and an adjustment component, provides support for the battery box inside when an opening is made, and adjusts the position of the auxiliary component to center it at the opening location. In this way, when supporting the battery box, it can also position the battery box during the opening. This design can reduce the problem of cracking when the battery box is opened, and also provide a positioning effect during the opening process. Attached Figure Description

[0027] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0028] Please combine Figures 1-6This embodiment of a battery box heat dissipation hole opening device includes a drilling machine 1, a drilling table 2 installed in the middle of the drilling machine 1, an auxiliary component that can position and support the battery box on the top side of the drilling table 2, an adjustment component that drives the auxiliary component to adjust its position at the bottom, a sliding groove 5 opened on the top of the drilling table 2, and the auxiliary component includes a support box 301 disposed on the top side of the drilling table 2 and two sliding blocks 302 that are slidably disposed inside the sliding groove 5.

[0029] When the sliding block 302 moves away from the inner wall of the sliding groove 5, it will hold the support box 301 in place inside the support box 301, thereby fixing the position of the support box 301 and facilitating the support and positioning of the battery box that needs to be drilled.

[0030] The support box 301 has its opening facing downwards, and a positioning hole is provided on the top side of the support box 301. The tops of the two sliding blocks 302 extend upwards into the interior of the support box 301.

[0031] Both sliding blocks 302 have insertion slots 6 on their tops. Limiting blocks 7 are fixedly installed inside both insertion slots 6. Limiting strips 8 are provided on the opposite sides of both sliding blocks 302. Connecting blocks 9 are fixedly installed on the side of both limiting strips 8 near the adjacent sliding block 302. One side of both connecting blocks 9 extends into the interior of the adjacent insertion slots 6. Insertion interfaces that are compatible with the limiting blocks 7 are provided at the bottom of both connecting blocks 9. Both connecting blocks 9 are inserted into the adjacent sliding blocks 302 through the adjacent limiting blocks 7.

[0032] The limiting strip 8 and the connecting block 9 are inserted into the insertion slot 6 of the sliding block 302. This fixes the position of the two limiting strips 8 and the position of the support box 301 that abuts against them, thereby preventing the support box 301 from shifting.

[0033] The adjustment assembly includes a bidirectional threaded rod 401 disposed inside the sliding groove 5. Both ends of the bidirectional threaded rod 401 pass through the drilling table 2 and extend to the outside of which a rotating block 402 is fixedly installed.

[0034] Both sliding blocks 302 are threaded onto the bidirectional threaded rod 401.

[0035] Rotating the two rotating blocks 402 will cause the bidirectional threaded rod 401 to rotate.

[0036] Rotation of the bidirectional threaded rod 401 will cause the two sliding blocks 302 to move closer to or further apart.

[0037] Each rotating block 402 has a fixing plate 10 fixedly installed on both sides of the drilling table 2. Each fixing plate 10 has a friction block 11 on one side. Each friction block 11 has a plurality of push rods 12 fixedly installed on the side away from the rotating block 402. One end of each push rod 12 passes through the adjacent fixing plate 10 and is fixedly installed with a limiting block. Each push rod 12 is fitted with a push spring 13. Both ends of each push spring 13 abut against the adjacent fixing plate 10 and the friction block 11, respectively.

[0038] After the operator manually rotates the rotating block 402, it will come into contact with the friction block 11. Thus, under the restriction of the friction block 11, the rotating block 402 cannot rotate automatically due to vibration.

[0039] The implementation principle of the battery box heat dissipation hole opening device in this application embodiment is as follows: the matching limiting strip 8 and connecting block 9 are inserted into the insertion slot 6 of sliding block 302. The limiting block 7 and the insertion interface of connecting block 9 will prevent the connecting block 9 from sliding left and right. After the bidirectional threaded rod 401 rotates, the movement of the two sliding blocks 302 will move the connecting block 9 and the limiting strip 8 together. Then, the support box 301 is placed on top, covering the two sliding blocks 302 and the limiting strip 8 inside the support box 301.

[0040] Next, the worker manually rotates the two rotating blocks 402, which allows the bidirectional threaded rod 401 to rotate. The rotation of the bidirectional threaded rod 401 causes the two sliding blocks 302 to move in opposite directions. After the sliding blocks 302 move, they abut against the sides of the support box 301 from the inside. Furthermore, the two ends of the limiting strip 8 abut against the upper and lower sides of the support box 301. Thus, the left and right sides and the upper and lower sides of the support box 301 are all abutted, and the support box 301 will not move.

[0041] The push spring 13 will push the friction block 11 to stay in contact with the rotating block 402, preventing the rotating block 402 from rotating automatically due to vibration during drilling.

[0042] Finally, the staff can place the battery box cover that needs to be drilled on the support box 301 to drill the hole. After drilling is completed, the staff can remove the battery box by hand.

[0043] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
