DETAILED DESCRIPTION

[0041] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments so that those skilled in the art can implement the invention with reference to the description.

[0042] It should be understood that terms such as “having”, “including” and “comprising” used herein do not preclude the existence or addition of one or more other elements or combinations thereof.

[0043] like Figures 1-13 As shown, the present invention provides a battery pack that is easy to disassemble and fix, including: an upper cover 1, a lower shell 2 and a battery body 3, the battery body 3 and related circuit components (such as Figure 3 As shown, the charging plate 31, PC sheet 32, shock-absorbing rubber ring 33, etc. are arranged in the lower shell 2, and the upper cover 1 is connected to the lower shell 2 through the middle cover 4. The middle cover 4 seals the battery body 3 in the lower shell 2. The upper cover 1 and the middle cover 4 are detachably connected. A connecting component is provided on the upper cover 1, and the connecting component is movably connected to the upper cover 1. The connecting component extends to the outside of the upper cover 1 and is connected to the snap-in slot on the device. A plurality of compression springs are provided between the battery pack and the mounting surface of the device. The springs are evenly distributed around the battery pack (usually located on the mounting surface where the device contacts the bottom of the battery pack). When the connecting component is unlocked, the compression spring releases the stored elastic potential energy, providing an outward thrust to the battery pack, helping the user to remove the battery pack from the device more easily. At the same time, the elastic force of the spring can buffer the impact force during the disassembly and assembly process to a certain extent, protecting the battery pack and the device from damage.

[0044] The connecting assembly includes an operating member, a resetting member, and a connecting member;

[0045] The operating member is movably connected to the upper cover 1 and is used to control the connection and separation between the connecting member and the device, helping the user to easily install the battery pack on the device or remove it from the device. To facilitate user operation, the surface of the operating member is designed with a non-slip texture, and the position and angle of the operating member are ergonomically designed to ensure that the user can easily and comfortably perform the unlocking operation through the operating member;

[0046] The reset member is provided between the upper cover 1 and the connecting member, and / or between the upper cover 1 and the operating member, and the reset member provides a force for the connecting member so that the connecting member always has a tendency to flip or extend in a direction away from the upper cover 1;

[0047] The connector extends from the inside of the upper cover 1 to the outside of the upper cover 1 and is used to connect the battery pack to the device and fix it on the device.

[0048] The top of the upper cover 1 is provided with a receiving groove, and the side wall of the upper cover 1 and / or the side wall of the middle cover 4 are provided with a movable groove, and the receiving groove is provided on the outer top surface of the upper cover 1 and is connected to the movable groove;

[0049] The operating member is disposed in the receiving slot, thereby reducing the size of the battery pack and being movably connected to the receiving slot;

[0050] The connecting member extends to the outside of the upper cover 1 through the movable groove. In order to increase the firmness of the connection, the connecting member can be a hook adapted to the snap-fit ​​groove.

[0051] The working principle and beneficial effects of the above technical solution: Through the design of the above structure, the battery pack can be quickly and conveniently disassembled and fixed, which significantly shortens the operation time and improves the use efficiency. It ensures that the battery pack has good stability and reliability in a fixed state and can adapt to different use environments and working conditions. The structural design is simple and reasonable, easy to manufacture and assemble, and reduces production costs. At the same time, it has a certain versatility and can be applied to a variety of equipment of different specifications and types. The present invention is applicable to a variety of fields such as electric vehicles, electric bicycles, power tools, energy storage power stations, etc. In the field of electric vehicles, it can significantly shorten the battery replacement time and improve the use efficiency of electric vehicles; in the field of power tools and energy storage equipment, the structure can facilitate users to replace and maintain the battery pack, reduce the use cost, and improve the reliability and service life of the equipment. Therefore, this battery pack structure has broad application prospects and market value.

[0052] In the first embodiment, the operating member is the first operating member 51, the reset member is the first reset member, the connecting member is the first connecting member 71, the accommodating groove is the first accommodating groove, and the movable groove is the first movable groove. The first accommodating groove and the first movable groove can be connected to each other, for example, respectively on the outer top surface of the upper cover 1 and the side wall of the upper cover 1, and located at the corner where the outer top surface and the side wall are connected, forming a groove with openings on the top surface and the side surface; the first accommodating groove and the first movable groove can also be set separately, the first accommodating groove is set on the upper cover 1, and the first movable groove is set at the bottom of the side wall of the upper cover 1 (or the top of the side wall of the middle cover 4). Take the first accommodating groove and the first movable groove as an example, both of which are set on the upper cover 1, and the two are connected to each other to form a groove with openings on the top surface and the side surface.

[0053] The top of the first operating member 51 is located at the top opening of the first receiving groove, and the bottom is connected to one end of the first connecting member 71. The other end of the first connecting member 71 extends to the outside of the upper cover 1, forming a Figure 1 The L-shaped structure shown in FIG. 5 is a schematic diagram of an embodiment of the present invention, and a first rotating shaft 81 is provided at the connection between the first operating member 51 and the first connecting member 71 . The first rotating shaft 81 is movably connected to the first accommodating groove through a first resetting member, and the first resetting member can be a torsion spring.

[0054] The first embodiment can be directly set on the upper cover 1, so the sealing between the upper cover 1 and the middle cover 4 is the best among the three embodiments of the present application. Different upper covers 1 or connecting components of different sizes and models can be replaced according to the size and model of the battery pack and the equipment. It is suitable for mass production and is also suitable for use in small-volume and light-weight battery packs.

[0055] In the first embodiment, the connecting assembly can be unlocked by rotating counterclockwise around the first rotating shaft 81. Figure 1 can also be the first shaft 81 as the axis, the clockwise rotation mode, unlocking, depending on the direction of rotation, the contact position of the hand and the first operating member 51 is also different.

[0056] Furthermore, we provide an embodiment suitable for small and medium-sized battery packs as a second embodiment. In this embodiment, the operating member is the second operating member 52, the reset member is the second reset member 62, the connecting member is the second connecting member 72, the accommodating groove is the second accommodating groove, and the movable groove is the second movable groove;

[0057] Because in this embodiment, the second receiving groove is communicated with the interior of the upper cover 1, and the sealing between the upper cover 1 and the middle cover 4 is poor, the second movable groove can be set on the middle cover 4, such as Figure 4 and Figure 5 As shown, the inner wall of the second receiving groove is provided with a sliding groove for the second operating member 52 to slide. Whether in a locked state or an unlocked state, a portion of the second operating member 52 is always located in the sliding groove, thereby preventing the second operating member 52 from falling out of the sliding groove. The sliding groove is located on the inner wall of the second receiving groove opposite to the second movable groove, as shown in FIG. Figures 2 to 5 As shown;

[0058] The top of the second operating member 52 is located at the top opening of the second receiving groove, and the bottom is connected to one end of the second connecting member 72, and the other end of the second connecting member 72 extends from the second movable groove to the outside of the middle cover 4. The second operating member 52 and the second connecting member 72 are L-shaped. Figure 4 and Figure 5 As shown, a groove for installing the second reset member 62 is provided on a side of the second operating member 52 facing the slide groove (or a side located in the slide groove), and the second operating member 52 is connected to the upper cover 1 through the second reset member 62 .

[0059] A first limiting member 91 is provided in the second receiving groove (usually at the inner bottom of the second receiving groove), and a second limiting member 92 is provided on the second operating member 52 (or the second connecting member 72). When the battery pack is locked, the first limiting member 91 abuts against the second limiting member 92. Figure 4 and Figure 5As shown; when the battery pack is unlocked, the first limiting member 91 is separated from the second limiting member 92.

[0060] The first limiting member 91 is provided on the inner wall opposite to the sliding groove, and the top surface of the first limiting member 91 is arc-shaped, so as to guide the movement direction of the finger inserted into the second receiving groove.

[0061] A baffle 11 is provided on the inner top surface of the upper cover 1 , and one end of the second restoring member 62 abuts against the baffle 11 , and the other end abuts against the second operating member 52 .

[0062] When installing the battery pack, align the battery pack with the installation position on the device and gently push it in. The second connecting member 72 will retract when squeezed and squeeze the second restoring member 62. When the second connecting member 72 reaches a position relative to the card slot of the device, the second restoring member 62 returns to its original state, so that the second connecting member 72 is firmly stuck in the card slot of the device, thereby fixing the battery pack.

[0063] The second implementation is the same as the first implementation, both using finger pressing to lock and unlock. The corresponding battery pack is of moderate size and weight, and the battery pack can be removed from or placed in the device with just one hand. For battery packs that are larger in size and heavier and cannot be taken in and out with one hand, we provide a third implementation.

[0064] In this embodiment, the operating member is the third operating member 53, the reset member is the third reset member 63, the connecting member is the third connecting member 73, the accommodating groove is the third accommodating groove, and the movable groove is the third movable groove;

[0065] The third operating member 53 is composed of a handle 531 and a transmission rod 532. A second rotating shaft 82 is provided on the top of the transmission rod 532. The transmission rod 532 is movably connected to the handle 531 through the second rotating shaft 82, so that the handle 531 can be flipped around the second rotating shaft 82 as the rotation axis and placed flat in the third receiving groove when not in use. Figure 6 As shown, it can be operated upright when in use. Figure 10 and Figure 11 shown.

[0066] The transmission rod 532 passes through the upper cover 1 from the inner bottom surface of the third accommodating groove and extends into the upper cover 1. A third reset member 63 is provided on the transmission rod 532. The third reset member 63 is located inside the upper cover 1. A third limit member 93 is provided on the inner top surface of the upper cover 1. A fourth limit member 94 is provided on the transmission rod 532. The third connecting member 73 is provided on the transmission rod 532.

[0067] The inner bottom surface of the third receiving groove is provided with a through hole, the inner diameter of which is not less than the outer diameter of the transmission rod 532, so that the transmission rod 532 can move up and down in the axial direction. The transmission rod 532 extends into the upper cover 1 through the through hole. The third limiting member 93 is tubular and is sleeved on the outside of the transmission rod 532. Figure 7-Figure 9 、 Figure 12 and Figure 13 As shown, the top of the third stopper 93 is connected to the inner top surface of the upper cover 1, and the inner diameter of the third stopper 93 is larger than the inner diameter of the through hole, so that the inner bottom surface of the upper cover 1 forms a step inside the third stopper 93 for abutting the third reset member 63, as shown in FIG. Figure 9 As shown, the third reset member 63 is located in the third limiting member 93, and a slot is provided at the bottom of the third limiting member 93. The fourth limiting member 94 can be a limiting column and is provided along the radial direction of the transmission rod 532. Figure 7 and Figure 9 As shown, one end of the third reset member 63 is connected to the inner top surface of the upper cover 1 , and the other end is connected to the fourth limit member 94 . The third connecting member 73 is provided on the transmission rod 532 and is located below the fourth limit member 94 .

[0068] Furthermore, the fourth limit member 94 divides the transmission rod 532 into two parts, the upper and lower parts. The part located below the fourth limit member 94 is provided with an external thread. The third connecting member 73 is composed of a clamping plate and two nuts. The clamping plate is sleeved on the part with the external thread of the transmission rod 532. The clamping plate is clamped up and down by the nuts. By adjusting the relative position of the nut on the transmission rod 532, the relative position of the clamping plate can be adjusted.

[0069] When the connecting assembly is in a locked state, the fourth limit member 94 is located in the card slot of the third limit member 93, the handle 531 is placed flat in the third accommodating groove, and the end of the card plate of the third connecting member 73 away from the transmission rod 532 is located outside the upper cover 1 and is connected to the card slot of the device. The third reset member 63 is in a stressed state to prevent the fourth limit member 94 from falling out of the card slot of the third limit member 93.

[0070] When the locking state is released, the handle 531 is lifted from the third receiving groove. Figure 11 As shown, pressing down the handle 531 causes the fourth limiting member 94 to disengage from the slot of the third limiting member 93. When the handle 531 is pressed down, the battery pack will move downward, causing the hook-shaped third connecting member 73 to separate from the connecting slot of the device. Then, the handle 531 is rotated with the transmission rod 532 as the axis to rotate the third connecting member 73 to the inside of the upper cover 1, thereby releasing the lock between the battery pack and the device. Then, the downward pressure of the handle 531 is gradually reduced, so that the fourth limiting member 94 is stuck at the bottom of the third limiting member 93 and the lock is released. Figure 12 and Figure 13As shown, at this time, the third restoring member 63 is in a state of tension, and after the lock is released, the battery pack can be lifted from the device by the handle 531.

[0071] Through the above structural design, the third embodiment can be applied to battery packs with larger weight and volume.
