Description

Technical Field

[0001] The utility model relates to the technical field of battery boxes, in particular to a waterproof battery box. Background Art

[0002] When the battery box is used in a humid environment, water may enter the battery box, causing the inside of the battery box to rust, resulting in circuit short circuit, battery damage and other problems. Therefore, battery boxes with waterproof function are widely used. Existing waterproof battery boxes usually include a base and a top cover. A sealing ring is arranged between the base and the top cover, and the base and the top cover are locked by screws to squeeze the sealing ring to achieve sealing. For example, a waterproof battery box disclosed in Chinese patent CN205582990U includes a box body, and the adjacent surfaces of the base and the top cover of the box body are relatively provided with flanges and grooves. An elastic seal for the flange to be squeezed is embedded in the groove, and the top cover and the base are locked by screws evenly distributed on the four corners to achieve sealing. When installing this scheme, it is necessary to first place the elastic seal in the groove of the top cover, then align the top cover with the base, and finally tighten the screws in sequence. Among them, when the elastic seal is accommodated in the groove and covers the base downward, the elastic seal is easy to fall off from the groove under the action of gravity. At the same time, there are a large number of screws that need to be locked, and the degree of tightening of each screw will also affect the sealing of the elastic seal. In addition, due to the structure of the battery box, if multiple batteries need to be connected in series, such as 6, 8, 10, etc., the width of the existing battery box will be very large, which is not conducive to carrying. When used on the device to be connected, the space occupied is also large, so the capacity of the existing battery box is generally small. In summary, the existing waterproof battery box has the problems of inconvenient installation and small capacity. Utility Model Content

Example

[0034] Combination Figures 1 to 18 The present embodiment provides a waterproof battery box, including a base 1, an upper cover 2 and a bracket 3. The base 1 is provided with a receiving cavity 11. The upper cover 2 and the base 1 are detachably configured and are sleeved with an elastic sealing member 21 (such as an O-ring) for extrusion sealing with the inner wall of the receiving cavity 11. The bracket 3 is adaptively connected with the upper cover 2, and the bracket 3 can be placed in or removed from the receiving cavity 11 by moving the upper cover 2 in an operable manner. Among them, multiple battery installation slots 31 are provided on both sides of the bracket 3, and metal sheet sockets 32 are provided at both ends of each battery installation slot 31. The batteries 34 in each battery installation slot 31 are sequentially connected in series through corresponding metal sheets 33 and are electrically connected to the power line 4. The battery 34 can be a dry cell or a rechargeable battery, such as a lithium battery.

[0035] It should be mentioned that, in this embodiment, the upper cover 2 and the base 1 are detachable, which can facilitate the replacement of the battery 34. The upper cover 2 is provided with an elastic seal 21 to achieve a waterproof effect. At the same time, the elastic seal 21 is provided on the upper cover 2 and then assembled with the base 1 to prevent the elastic seal 21 from slipping during the assembly process. In addition, the bracket 3 is adapted to be connected with the upper cover 2, and the upper cover 2 can be disassembled to synchronously insert or remove the bracket 3, so that the battery 34 can be installed in the battery installation slots 31 on both sides of the bracket 3, so as to realize a double-row arrangement of the battery 34, thereby saving the battery box space and increasing the capacity. At the same time, by inserting the metal sheet 33 into the socket 32 ​​to electrically connect with the battery 34, the circuit line can be simplified, the length of the battery installation slot can be shortened, and the overall volume of the battery box can be further reduced.

[0036] In a preferred embodiment, the extending direction of the accommodating cavity 11 is the same as the length direction of the battery 34, and the opening position of the accommodating cavity 11 is used to connect with the upper cover 2. Exemplarily, the accommodating cavity 11 is formed by drawing the shell of the base 1 during drawing, and the parting surface of the base 1 can be set on the top end surface of the base 1 during the mold forming process, thereby avoiding the formation of a parting line on the side of the base 1, and improving the aesthetics of the battery 34 box.

[0037] On the basis of the above-mentioned embodiment, in an optional embodiment of the utility model, the upper cover 2 includes a top plate 22 for shielding the accommodating cavity 11 and a connecting portion 23 that is retracted and convexly arranged along the top plate 22, and a sealing groove 231 is concavely arranged along the outer wall of the connecting portion 23, and the elastic sealing member 21 is sleeved in the sealing groove 231, so that the elastic sealing member 21 can be limited, and the elastic sealing member 21 can be prevented from slipping off, thereby ensuring the sealing effect. Preferably, the top plate 22 is in the shape of a runway, the sealing groove 231 is arranged in a square with the top plate 22, and the elastic sealing member 21 is an anisotropic sealing ring arranged in the shape of a runway, and is made of rubber or silicone.

[0038] Furthermore, the connection portion 23 is provided with a plurality of slots 232, each of which is located below the sealing slot 231, and the bracket 3 is provided with buckles 35 corresponding to the slots 232, and the buckles 35 are engaged with the slots 232 to connect the upper cover 2 and the bracket 3, so that the upper cover 2 drives the bracket 3 to move synchronously. In addition, for upper covers 2 with different appearances, only the slots 232 at the same position need to be provided to adapt to the same bracket 3, thereby improving the compatibility of the bracket 3 and reducing the production cost.

At the same time, a plurality of grooves 371 are arranged along the periphery of the upper end surface 36 and the lower end surface 37 of the bracket 3. On the one hand, the friction of the bracket 3 during the placement process can be reduced, and on the other hand, the bracket 3 can be prevented from squeezing the gas in the accommodating cavity 11 to generate resistance during the placement process. The arrangement of the grooves 371 is conducive to air discharge and reduces resistance during the installation process.

The metal piece 13 is preferably made of copper or stainless steel, so as to avoid the problem of slipping of the screw 5 during the tightening process. In addition, the plurality of protruding teeth 132 provided on the outer wall of the metal piece 13 can increase the bite force between the metal piece 13 and the plastic piece, and prevent the metal piece 13 from falling off the base 1.

[0042] On the basis of the above-mentioned embodiment, in an optional embodiment of the utility model, the upper cover 2 is provided with an outlet hole 25 for the power cord 4 to pass through, and a waterproof plug 41 is installed or formed on the power cord 4 to seal with the outlet hole 25, and a sealing ring 411 and / or an arc-shaped protrusion 412 are formed on the waterproof plug 41 to abut and seal with the inner wall of the outlet hole 25. Preferably, the waterproof plug 41 and the power cord 4 are formed by secondary injection molding, wherein a sealing ring 411 (O-ring) is sleeved on the waterproof plug 41, and arc-shaped protrusions 412 are formed at the upper and lower ends of the sealing ring 411 to further seal the outlet hole 25, and at the same time, the O-ring can be partially shielded to prevent the O-ring from leaking out of the gap of the outlet hole 25, thereby enhancing the aesthetics.
