Description

Technical Field

[0001] This utility model relates to the field of battery pack lead wire technology, specifically an adjustable battery pack lead wire device. Background Technology

[0002] The battery pack is composed of multiple battery packs integrated together. All the battery packs are connected to a single wire, and the wire is led out from the battery pack to the outside by a lead-out device. The battery pack can be connected to external devices through this wire.

[0003] The lead-out device on the existing battery pack has a simple structure. After the wire extends from the lead-out device, the length of the extended part is fixed. When the distance between the battery pack and the external device is close, the length of the wire is too long relative to the distance between the battery pack and the device. The lead-out device cannot retract the excess part of the wire, so the wire will drag between the battery pack and the device, affecting the connection of other lines. Moreover, after the wire is led out by the lead-out device, it is directly exposed to the outside, making the wire easy to be damaged. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide an adjustable battery pack lead wire outlet device.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an adjustable battery pack lead-out device, which is located on the side of the battery pack body, with the battery lead-out device located inside.

The movable disk is a circular block, and a groove is formed on the outer periphery of the circular block. The battery lead-out coil is wound in the groove. A through hole is formed at the center of the rear side of the movable disk, and a fixing shaft is provided in the through hole and fixedly connected to the fixing plate. An electric slip ring is fitted on the outer side of the fixed shaft. The battery wire is electrically connected to the battery pack body through the electric slip ring. An outlet is provided on the side of the fixed plate away from the battery pack body. A wire sheath is provided on the outer side of the fixed plate. The wire sheath consists of a fixed sleeve, a movable sleeve, and a sleeve. The fixed sleeve is fixedly connected to the outlet. The sleeve is connected between the fixed sleeve and the movable sleeve. The outer end of the battery wire extends from the outlet and passes through the inner side of the wire sheath. The fixed sleeve is fixedly connected to the outer end of the battery wire. A connecting rod is fixedly connected to the front side of the movable plate. An opening is provided on the front side of the fixed plate. The connecting rod is movably connected in the opening and extends to the outside of the fixed plate. A crank is fixedly connected to the end of the connecting rod.

[0006] As described above, a number of locking teeth are fixedly connected to the front edge of the movable disk, and a movable plate is provided above the movable disk that is movably connected to the fixed plate. A locking block that engages with the locking teeth is fixedly connected to the movable plate. Both the locking teeth and the locking block are triangular, and the locking block and the locking teeth are arranged in opposite directions.

[0007] As described above, a first spring is fixedly connected between the side of the movable plate facing away from the movable disc and the fixed plate. A slot is provided on the front side of the fixed plate. A lever is fixedly connected to the movable plate, and the lever extends through the slot to the outside of the fixed plate.

[0008] As described above, the opposite ends of the fixed sleeve and the movable sleeve are both closed and have through holes. The sleeve is a corrugated tube, with both ends inserted into the fixed sleeve and the movable sleeve respectively. The sleeve is fixedly connected to both the fixed sleeve and the movable sleeve. The battery wire passes through the through hole and the sleeve in sequence.

[0009] As described above, both the fixed sleeve and the movable sleeve are round tubes, and the ends of the movable sleeve and the fixed sleeve in the same direction are bent outward with scraped edges. The movable sleeve is sleeved on the outside of the fixed sleeve, and annular magnets are fixedly connected to the opposite sides of the scraped edges of the fixed sleeve and the movable sleeve.

[0010] As described above, a first guide rod is provided in the groove of the movable disk. The first guide rod is arranged parallel to the axis of the movable disk and is slidably connected in the groove.

[0011] As described above, two second guide rods are provided between the movable disc and the outlet, and both second guide rods are movably connected to the fixed plate. Each of the two second guide rods has a limiting groove on its periphery that matches the battery wire.

[0012] As described above, the groove has sliding grooves on both the front and rear sides, and sliders are slidably connected in both sliding grooves.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] like Figure 1-6 As shown, this utility model provides a technical solution: an adjustable battery pack lead wire lead-out device. The lead-out device is located on the side of the battery pack body 1, and the battery lead wire 3 is located inside the lead-out device. The lead-out device includes a fixing plate 2, and an mounting plate 4 is integrally connected to the periphery of the fixing plate 2. The mounting plate 4 has mounting holes for matching screws. The fixing plate 2 is fixed to the outside of the battery pack body 1 by the mounting plate 4 and screws. The fixing plate 2 is hollow. A movable disk 5 is movably connected inside the fixing plate 2. The movable disk 5 is a circular block, and a groove is opened on the outer periphery of the circular block. The battery lead wire 3 is wound in the groove. A through hole is opened on the rear side of the movable disk 5 at the axis. A fixing shaft 12 is installed in the through hole and is fixedly connected to the fixing plate 2. An electric slip ring 13 is sleeved on the outside of the fixing shaft 12. The battery lead wire 3 is electrically connected to the battery pack body 1 through the electric slip ring 13. The electric slip ring 13 consists of an inner ring and an outer ring, and the inner ring and the outer ring can rotate. The inner ring is fixedly connected to the fixed shaft 12 and electrically connected to the internal wires of the battery pack body 1. The outer ring is fixedly connected to the movable disk 5 and electrically connected to the inner end of the battery wire 3. The fixed plate 2 has an outlet on the side away from the battery pack body 1. The outer side of the fixed plate 2 is provided with a wire sheath 6. The wire sheath 6 is composed of a fixed sleeve 602, a movable sleeve 601, and a sleeve 603. The fixed sleeve 602 is fixedly connected to the outlet. The sleeve 603 is connected between the fixed sleeve 602 and the movable sleeve 601. The outer end of the battery wire 3 extends from the outlet and passes through the inner side of the wire sheath 6. The fixed sleeve 602 is fixedly connected to the outer end of the battery wire 3. A connecting rod is fixedly connected to the front side of the movable disk 5. An opening is opened on the front side of the fixed plate 2. The connecting rod is movably connected in the opening and extends to the outside of the fixed plate 2. A crank 8 is fixedly connected to the end of the connecting rod.

[0026] According to the overall structure of the device, the fixing plate 2 is installed on the outside of the battery pack body 1 by the mounting plate 4 and screws. The battery wires 3 are coiled and stored by the fixing plate 2 and the movable plate 5, providing a regular place for the excess battery wires 3, thereby preventing the battery wires 3 from dragging between the battery pack body 1 and the equipment. The outer end of the battery wires 3 extends from the outlet and passes through the wire sheath 6 composed of the fixing sleeve 602, the movable sleeve 601 and the sleeve 603. When the battery pack body 1 is connected to the external equipment, the movable sleeve 601 is pulled outward, thereby moving the battery. When the lead wire 3 is pulled outward, the electrical connection between the battery lead wire 3 and the battery pack body 1 is maintained by the electric slip ring 13 when the movable disk 5 rotates. At the same time as the battery lead wire 3 is pulled out, the movable sleeve 601 and the fixed sleeve 602 are separated, thereby unfolding the sleeve 603 and covering the outside of the pulled-out part of the battery lead wire 3. The lead wire sheath 6 provides protection for the pulled-out part of the battery lead wire 3 to prevent damage to the battery lead wire 3. When the battery pack body 1 is disconnected from the equipment, the crank handle 8 can be turned to drive the movable disk 5 to rotate and rewind the battery lead wire 3 into the fixed plate 2 to prevent the battery lead wire 3 from being exposed and damaged.

[0027] like Figure 3 , 5 As shown, several locking teeth 9 are fixedly connected to the front edge of the movable disk 5. A movable plate 14 is provided above the movable disk 5 and is movably connected to the fixed plate 2. A locking block 16 that engages with the locking teeth 9 is fixedly connected to the movable plate 14. Both the locking teeth 9 and the locking block 16 are triangular, and the locking block 16 is arranged opposite to the locking teeth 9. A first spring 17 is fixedly connected between the side of the movable plate 14 facing away from the movable disk 5 and the fixed plate 2. A slot is opened on the front side of the fixed plate 2. A lever 15 is fixedly connected to the movable plate 14, and the lever 15 extends through the slot to the outside of the fixed plate 2.

[0028] The movable disk 5 is fixed by the engagement of the triangular locking teeth 9 and the locking block 16, restricting the rotation of the movable disk 5 and thus fixing the pull-out length of the battery wire 3. The lever 15 can drive the movable plate 14 to deflect, thereby moving the locking block 16 away from the locking teeth 9 and releasing the restriction on the movable disk 5. At this time, the battery wire 3 can be pulled out or retracted. When the movable plate 14 deflects, it will compress the first spring 17. When the lever 15 is released, the elastic force of the first spring 17 pushes the movable plate 14 to reset, so that the locking block 16 engages with the locking teeth 9, and fixes the movable disk 5 again.

[0029] like Figure 4As shown, the opposite ends of the fixed sleeve 602 and the movable sleeve 601 are both closed and have through holes. The sleeve 603 is a corrugated tube, and its two ends are respectively inserted into the fixed sleeve 602 and the movable sleeve 601. The sleeve 603 is fixedly connected to both the fixed sleeve 602 and the movable sleeve 601. The battery wire 3 passes through the through hole and the sleeve 603 in sequence. The fixed sleeve 602 and the movable sleeve 601 are both round tubes, and the ends of the movable sleeve 601 and the fixed sleeve 602 in the same direction are bent outward with scraped edges. The movable sleeve 601 is sleeved on the outside of the fixed sleeve 602. The opposite sides of the scraped edges of the fixed sleeve 602 and the movable sleeve 601 are fixedly connected to annular magnets 18.

[0030] The corrugated tube structure allows the sleeve 603 to extend and retract along the length of the battery wire 3 as it is pulled out. When the battery wire 3 is pulled out, the sleeve 603 covers the outside of the battery wire 3, thus protecting it from damage. When the battery wire 3 is retracted, the movable sleeve 601 can cover the outside of the fixed sleeve 602. The movable sleeve 601 and the fixed sleeve 602 are sealed together by a sealing ring to close the outlet, preventing external debris from getting stuck in the outlet and affecting the pulling out of the battery wire 3. The scraping edge and the annular magnet 18 allow the movable sleeve 601 and the fixed sleeve 602 to be magnetically attracted and fixed, thus fixing the movable sleeve 601 when the battery wire 3 is retracted.

[0031] like Figure 2 , 6 As shown, a first guide rod 10 is provided in the groove of the movable disk 5. The first guide rod 10 is arranged parallel to the axis of the movable disk 5 and is slidably connected in the groove. Two second guide rods 7 are provided between the movable disk 5 and the outlet. Both second guide rods 7 are movably connected to the fixed plate 2. Limiting grooves matching the battery wires 3 are opened on the periphery of both second guide rods 7. Sliding grooves are opened on both the front and rear sides of the groove. Sliding sliders 11 are slidably connected in both sliding grooves. The two ends of the first guide rod 10 are movably connected to the adjacent sliding sliders 11. A second spring 19 is fixedly connected between the two sliding sliders 11 and the sliding groove.

[0032] The battery wire 3, wound on the movable disk 5, is secured and limited by the first guide rod 10 to prevent it from loosening and tangling between different numbers of turns. The battery wire 3 is pulled and limited by the second guide rod 7 to facilitate its pull-out from the fixed plate 2. The first guide rod 10 can move within the groove through the slide and slider 11. When the battery wire 3 is pulled out, the number of turns on the movable disk 5 decreases, and the battery wire 3 separates from the first guide rod 10. At this time, the first guide rod 10 moves towards the battery wire 3 under the force of the second spring 19, keeping it in contact with the battery wire 3. When the battery wire 3 is wound up, the number of turns increases, and the retraction of the battery wire 3 pushes the first guide rod 10 outward and compresses the spring, thus keeping the first guide rod 10 in contact with the battery wire 3, thereby securing and limiting the battery wire 3 and preventing it from loosening.

[0033] Working principle: When the battery pack body 1 needs to be connected to an external device, push the lever 15 to cause the movable plate 14 to separate the locking block 16 from the locking tooth 9, releasing the fixation of the movable disc 5. Then pull the movable sleeve 601 outward to pull the battery wire 3 outward. At this time, the movable sleeve 601 and the fixed sleeve 602 separate, allowing the sleeve 603 to unfold and cover the outside of the battery wire 3 for protection. After pulling the battery wire 3 to a suitable length, release the lever 15. The movable plate 14 returns to its original position under the elastic force of the first spring 17, causing the locking block 16 to engage with the locking tooth 9 and fix the movable disc 5. When the battery pack body 1 is disconnected from the device, push the lever 15 again and turn the rocker handle 8 to drive the movable disc 5 to rotate, winding the battery wire 3 into the fixed plate 2.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
