Description

Technical Field

[0001] The utility model relates to the technical field of battery assembly devices, in particular to a battery assembly package. Background Art

[0002] Chinese Patent with publication number CN110931697A discloses a battery combination structure and a combined battery pack. The battery pack includes a connecting column. On the outer wall of the connecting column, relying positions are circumferentially and spacedly recessed. Each relying position can be filled with a group of battery units. Each group of battery units includes at least one battery. An adhesive layer is coated on the surface of the relying position. The outer wall of the battery can adhere to the adhesive layer to play a role of pre-positioning. The battery pack further includes cover plates arranged at both ends of the battery. The cover plates are made of conductive materials. A conductive connecting piece is arranged between the cover plates. After all the battery units rely on and adhere to the connecting column, all the battery units are connected in series by welding the connecting piece and the cover plates to each other. After being connected in series, a battery pack body is formed. The outside of the battery pack body is integrally wrapped with a protective layer.

[0003] The above-mentioned battery pack is formed by combining multiple batteries and is mostly used in power tools. During use, each battery may be damaged to varying degrees. When some of the batteries are damaged, the most economical way for consumers is to replace the damaged batteries. However, most of the above-mentioned protective layers are formed by tightly wrapping with a plastic film and cannot be restored once disassembled. Without the protective layer, it is very difficult to fix the battery and the cover plate only by relying on the adhesive layer on the surface of the relying position, resulting in the battery pack being unable to be used normally. And this plastic film needs to be wrapped by specific mechanical equipment. Therefore, consumers can only solve the problems caused by the damage of some batteries in the battery pack by replacing the whole battery pack, resulting in a high replacement cost. Therefore, there is still room for improvement in this battery pack. Summary of the Utility Model

[0004] Aiming at the reason that the existing combined battery or battery pack cannot be restored after the protective layer is disassembled, when only some batteries in the battery pack are damaged, consumers still need to replace the whole battery pack, resulting in a high replacement cost. The purpose of the utility model is to provide a battery assembly package that can replace any single battery and still be able to be used normally after replacement.

[0005] In order to solve the above technical problems, the utility model is solved by the following technical solutions:

[0006] A battery assembly pack includes a connecting column and several batteries. Mounting seats are provided at both ends of the connecting column. At least one mounting seat is detachably connected to the connecting column. The outer wall of the connecting column is circumferentially and spacedly recessed with mounting positions that cooperate with the mounting seats to form positions for the batteries to be installed and rely on. Connecting parts that can conduct electricity are provided at both ends of the mounting positions. At least one elastic connecting piece that can elastically abut against the electrodes of the battery and has conductivity is provided on each pair of connecting parts. A protective sleeve that can wrap all the mounting positions is sleeved between the mounting seats along the connecting column. A limiting mechanism that can limit or release the protective sleeve from detaching from the mounting seat is provided on the mounting seat.

[0007] Adopting the above solution, the operation steps for taking and placing the batteries in this solution are as follows: First, the protective sleeve can be sleeved on one of the mounting seats and abutted against the mounting seat. Then, the batteries are successively placed into the mounting positions along the connecting column from the other end of the protective sleeve. After all the batteries are installed, the other mounting seat is installed. The elastic abutment between the elastic connecting piece and the battery is used to press the battery to form an effective conductive connection. During the installation process, the batteries are limited by the protective sleeve. After all the batteries are installed, the other mounting seat is installed. At this time, all the batteries are abutted by the elastic connecting pieces. At this time, even if the protective sleeve is pulled out from the mounting seat, the batteries will not scatter. Therefore, the protective sleeve in this solution can be repeatedly disassembled and assembled. After removing the protective sleeve, any battery in the battery assembly pack can be replaced. If a battery detaches from the mounting position due to external influence during the replacement process, the battery can also be reinstalled according to the above installation steps. In this solution, there is no need to set an adhesive layer at the mounting position, which will not stick to the battery and is convenient for taking and placing the battery. Therefore, when only a part of the batteries in the battery assembly pack are damaged, the user only needs to replace the damaged batteries, which can reduce the replacement cost, is more economical and practical, and can also indirectly reduce the cost of recycling waste batteries and is more environmentally friendly.

[0008] Preferably, the limiting mechanism includes a flange protruding from the outer wall of one of the mounting seats for one end of the protective sleeve to abut against and a movable limiting member elastically telescoped on the outer wall of the other mounting seat. When the movable limiting member pops out, it limits the protective sleeve from detaching from the mounting seat.

[0009] Preferably, the movable limiting member includes a push-button bead embedded in the outer wall of the mounting seat.

[0010] Adopting the above solution, when the protective sleeve is sleeved between the mounting seats, one end of the protective sleeve abuts against the flange on one of the mounting seats, and the push-button bead on the other mounting seat automatically pops out, limiting the protective sleeve between the two mounting seats. When replacing the battery, as long as the protective sleeve is pulled in the direction away from the flange, the protective sleeve is driven to squeeze the push-button bead to the retracted state, and then the protective sleeve can be taken out. At this time, the battery is still retained in the mounting position by being abutted by the elastic connecting piece, and people can pick out the damaged battery for replacement.

[0011] Preferably, at least two movable limiting members are spacedly arranged on the outer wall of the mounting seat.

[0012] Preferably, a matching structure is provided inside the protective cover to prevent the battery from shifting in the installation position.

[0013] Preferably, the matching structure includes a blocking block provided at the corresponding position of the inner wall of the protective cover and the installation position for abutting against the outer wall of the battery. The blocking block is made of an elastic material, and is in an elastic interference fit with the battery after being matched with the battery.

[0014] With the above solution, the inner wall size of the protective cover must be larger than the mounting seat to be smoothly sleeved therein. Therefore, there is a gap between the protective cover and the outer wall of the battery. During the use of the power tool, the vibration generated may cause the battery to shift, resulting in connection failure. Using the elastic interference of the blocking block against the battery can reduce the possibility of the battery shifting due to the above reasons and make the connection more stable.

[0015] Preferably, guiding inclined surfaces are provided at both ends of the blocking block.

[0016] With the above solution, during the process of the battery being inserted into the installation position, it gradually approaches the blocking block by means of the guiding inclined surface until it is in an elastic interference fit state, increasing the installation convenience.

[0017] Preferably, both mounting seats are detachably connected to the connecting columns.

[0018] With the above solution, multiple batteries can be quickly connected in series end to end to form a battery pack. The length of the battery pack increases. In this solution, as long as connecting columns of different lengths are separately produced, the requirements for battery packs of different lengths can be met, and the mounting seats remain unchanged. The above structure effectively reduces the outer profiles of the mounting seats and the connecting columns, further reducing the difficulty of mold design and the difficulty of demolding during production, facilitating design and production; moreover, the mounting seats and the connecting columns are generally plastic parts formed by injection molding. Separating production is convenient for demolding and blanking, and can effectively reduce the production cost.

[0019] Preferably, a slot for guiding the insertion of the connecting column is recessed on the surface of the mounting seat facing the connecting column, and a fastener for connecting and fixing the two is provided between the mounting seat and the connecting column.

[0020] The utility model has adopted the above technical solutions and has remarkable technical effects:

[0021] 1. The protective cover in this solution can be disassembled and reassembled repeatedly. After removing the protective cover, any battery in the battery assembly pack can be replaced. If a battery detaches from the installation position due to external influence during the replacement process, the battery can also be reinstalled. In this solution, there is no need to set an adhesive layer at the installation position, which will not stick to the battery and facilitates the removal and placement of the battery. Therefore, when only a part of the batteries in the battery assembly pack are damaged, the user only needs to replace the damaged batteries, which can reduce the replacement cost, is more economical and practical, and can also indirectly reduce the cost of recycling waste batteries, making it more environmentally friendly.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0030] The present utility model will be further described in detail below with reference to the drawings and embodiments.

[0031] Embodiment

[0032] A battery 2 assembly pack, according to Figure 1 、 2, as shown in Fig. 4, it includes a connecting column 1 and several battery sections 2. Mounting seats 3 are arranged at both ends of the connecting column 1. Circumferentially spaced depressions are provided on the outer wall of the connecting column 1 to form mounting positions 4 that cooperate with the mounting seats 3 for the installation and support of the batteries 2. At least one mounting seat 3 is detachably connected to the connecting column 1. In this embodiment, both mounting seats 3 are detachably connected to the connecting column 1. Connecting parts 5 that can conduct electricity are arranged at both ends of the mounting position 4. After all the batteries 2 are installed in the mounting position 4, conductive sheets are welded between the connecting parts 5 for series connection. At least one elastic connecting piece 51 that can elastically abut against the electrodes of the battery 2 and has conductivity is provided on each pair of connecting parts 5. In this embodiment, the elastic connecting piece 51 is a spring. A protective sleeve 6 that can wrap all the mounting positions 4 is sleeved between the mounting seats 3 along the connecting column 1. According to Figure 3 , as shown, a slot 11 for guiding and inserting the connecting column 1 is recessed on the surface of the mounting seat 3 facing the connecting column 1. A fastener for connecting and fixing the two is provided between the mounting seat 3 and the connecting column 1. In this embodiment, the fastener is a screw 12. A threaded hole 13 for cooperating with the screw 12 is provided at the end of the connecting column 1, and a through hole 14 for the screw 12 to pass through is provided at the bottom of the slot 11.

[0033] A limiting mechanism that can limit or release the protective sleeve 6 from detaching from the mounting seat 3 is provided on the mounting seat 3. According to Figure 4 , as shown, the limiting mechanism includes a flange 7 protruding from the outer wall of one of the mounting seats 3 for the end of the protective sleeve 6 to abut against, and a movable limiting member elastically telescoping on the outer wall of the other mounting seat 3. When the movable limiting member pops out, it limits the protective sleeve 6 from detaching from the mounting seat 3. According to Figure 3 、 5 , as shown, in this embodiment, the movable limiting member includes a pressing ball 8 embedded in the outer wall of the mounting seat 3. Three groups of pressing balls 8 are spaced on the outer wall of the mounting seat 3, and each group of pressing balls 8 is aligned with one mounting position 4.

[0034] A matching structure that can prevent the battery 2 from shifting on the mounting position 4 is provided inside the protective sleeve 6. According to Figure 2 、 6 , as shown in Fig. 7, the matching structure includes a resisting block 9 provided at the corresponding position of the inner wall of the protective sleeve 6 and the mounting position 4 for resisting against the outer wall of the battery 2. The resisting block 9 is made of an elastic material, and is in an elastic interference fit with the battery 2 after cooperation. Guide slopes 10 are provided at both ends of the resisting block 9.

[0035] Combining the above structures, referring to Figures 1 to 7It can be known that the protective cover 6 in this embodiment can be disassembled and assembled repeatedly. After removing the protective cover 6, any battery 2 in the battery 2 assembly package can be replaced. If the battery 2 detaches from the installation position 4 due to external influence during the replacement process, the battery 2 can also be reinstalled. In this solution, the adhesive layer is omitted at the installation position 4, which will not stick to the battery 2 and facilitates the removal and placement of the battery 2. Therefore, when only a part of the batteries 2 in the battery 2 assembly package are damaged, the user only needs to replace the damaged battery 2, which can reduce the replacement cost, is more economical and practical, and can also indirectly reduce the cost of recycling waste batteries 2, making it more environmentally friendly;

[0036] In this embodiment, the mounting base 3 and the connecting column 1 are detachably connected, which has two advantages:

[0037] The first is to facilitate the removal and placement of the battery 2. The operation steps for removal and placement are as follows: First, put the protective cover 6 on one of the mounting bases 3 and press against the mounting base 3, and then put the batteries 2 into the installation positions 4 one by one along the connecting column 1 from the other end of the protective cover 6. After all the batteries 2 are installed, then install the other mounting base 3, and use the elastic abutment between the elastic connecting member 51 and the battery 2 to press the battery 2 to form an effective electrical connection. During the installation process, the battery 2 is limited by the protective cover 6, and after all the batteries 2 are installed, then install the other mounting base 3;

[0038] The second is to facilitate production and design. The head and tail of multiple batteries 2 are butted to quickly form a series of battery 2 groups in series. After the battery 2 groups are formed, the length increases. In this solution, as long as the connecting columns 1 of different lengths are produced separately, the requirements for battery 2 groups of different lengths can be met, and the mounting base 3 remains unchanged. The above structure effectively reduces the outer contour of the mounting base 3 and the connecting column 1, further reducing the difficulty of mold design and the difficulty of demolding during production. Moreover, the mounting base 3 and the connecting column 1 are generally plastic parts formed by injection molding. Separating production facilitates demolding and blanking, and can effectively reduce the production cost.

[0039] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
