Description

Technical Field

[0001] The utility model belongs to the technical field of a battery-changing bottom bracket lock frame, and in particular relates to a battery-changing bottom bracket lock frame. Background Art

[0002] New energy is a device that uses battery modules as energy supply, such as new energy vehicles. When working, the battery modules integrated and installed on the battery rack provide kinetic energy for the vehicle.

[0003] However, the shortcomings of new energy equipment are also quite obvious. The battery module has a certain service life. When the battery module exceeds its service life, the battery's ability to provide electrical energy is reduced, the vehicle's endurance time and mileage are shortened, and other defects are manifested.

[0004] Therefore, when the battery reaches the end of its service life during the use of new energy equipment, the battery module needs to be replaced. Specifically, the battery module is removed from the frame and then replaced.

[0005] At present, the battery rack for installing the battery module is fixed on the vehicle frame, and bolts and other fastening structures are commonly used for fastening. However, with the increase of service life, bolts and other mounting structures are easy to rust at the mounting position, resulting in the difficulty of disassembly of the battery rack, such as bolt breakage. In the case of severe rust, the mounting position needs to be cut off and then replaced by welding.

[0006] Obviously, the traditional installation structure is not only cumbersome to disassemble and replace, but also once the above-mentioned rust occurs, the installation structure needs to be cut, which leads to damage to the battery rack and other structures during the disassembly and installation process. The damage to the structure greatly reduces the stability of the battery rack.

[0007] In the actual working process, the installation structure is often rusted and cut, and the battery rack is installed after disassembly. However, the welding position is weak, which leads to the breakage of the installation structure of the battery rack during use. The battery rack carrying the battery falls off the frame, which can easily cause safety accidents. Utility Model Content

[0008] Based on the above background, the purpose of the utility model is to provide a battery replacement base lock frame.

[0022] Preferably, a mounting plate for assembling the vertical seat body is fixedly connected to the cylindrical shell, and the mounting plate is fastened to the vertical seat body by a plurality of fastening bolts.

[0023] Preferably, the locking hole structure includes a circular hole portion that cooperates with the pin head, and side hole portions that are adapted to the locking protrusion are integrally formed on both sides of the circular hole portion.

[0043] Example 1

[0044] like Figure 1-5 As shown, a battery-swapping base lock frame includes a lock frame beam 1 fixedly mounted on a vehicle frame; specifically, the lock frame beam 1 is fastened to the vehicle frame beam by a bolt structure using an existing fastening method.

[0045] At the same time, the battery rack for installing the battery module is installed on the lock frame beam 1. The battery rack is installed on the lock frame beam 1 in a convenient disassembly installation mode, so that the lock frame beam 1 is used as a transfer structure, which is convenient for disassembly, replacement and maintenance of the battery rack and battery module structure.

[0046] Specifically, a plurality of rotating locking mechanisms 4 are assembled and connected to the locking frame beam 1 , and the battery rack can be detachably assembled on the locking frame beam 1 through the rotating locking mechanisms 4 .

[0047] Specifically, a long slot structure is provided on the right side wall of the lock frame beam 1; a plurality of installation openings are provided on the long slot structure, and the rotating locking mechanism 4 includes a card plate 45 fixedly installed on the lock frame beam 1 (the card plate 45 is limited in the installation opening by providing upper card slots on the side walls on both sides of the installation opening, and the card plate 45 is fixed after being connected and connected, and there is a gap between the card plate 45 and the slot wall of the long slot structure), and the rotating locking mechanism 4 also includes a pin fixed to the card plate 45 by a rotating pin, and the pin includes a pin head 421, and a protruding locking protrusion 4211 is integrally formed on the pin head 421. Specifically, two locking protrusions 4211 are symmetrically arranged at an angle of 180 degrees apart on the pin head 421.

[0048] Correspondingly, a locking hole structure 451 adapted to the pin head 421 and the locking protrusion 4211 is provided on the card plate 45. Under normal circumstances, the pin head 421 and the locking protrusion 4211 penetrate the locking hole structure 451 and are located on the inner side of the locking hole structure 451. When the locking head is rotated until the locking protrusion 4211 is vertical, it is blocked on the inner side of the locking hole structure 451.

[0049] Specifically, the lock hole structure 451 is adapted to the shape of the pin head 421-locking protrusion 4211, and the lock hole structure 451 is as follows: the lock hole structure 451 includes a circular hole portion that cooperates with the pin head 421, and side hole portions that are adapted to the locking protrusion 4211 are integrally formed on both sides of the circular hole portion. After the pin head 421 is rotated until the locking protrusion 4211 is in a horizontal state, the pin head 421 and the locking protrusion 4211 maintain the unlocking device, and the pin head 421 is rotated to a vertical state. The locking protrusion 4211 is blocked on the inner side of the circular hole portion, and it is now in a locked state.

[0050] At the same time, the pinning member also includes a screw rod 42 fixedly connected to the pin head 421, and the pinning member also includes a shell member threadedly connected to the screw rod 42; the battery rack is installed on the shell member.

[0051] Specifically, the screw rod 42 is rotated to adjust the posture of the pin head 421 - locking protrusion 4211 from a horizontal state to a vertical state (i.e., the locking protrusion 4211 is converted from horizontal to vertical and then blocked on the inner side of the locking hole structure 451).

[0052] Specifically, the shell member includes a cylindrical outer shell 41, and the screw 42 is threadedly connected to the cylindrical outer shell 41 (specifically, the right end position of the cylindrical outer shell 41, where an adaptive threaded hole structure is opened); the cylindrical outer shell 41 is fixedly connected to a mounting base, and the screw 42 passes through the mounting base; at the same time, the battery rack is fixedly mounted on the mounting base.

[0053] Specifically, the mounting base includes a vertical seat body portion 44 for fixing and mounting the cylindrical housing 41 (the pin head 421 also passes through the assembly hole position on the vertical seat body portion 44).

[0054] Correspondingly, a mounting plate 43 for assembling the vertical seat body 44 is fixedly connected to the cylindrical outer shell 41 (similarly, a through hole structure that overlaps the assembly hole on the vertical seat body 44 is provided on the mounting plate 43, and the pin head 421 passes through the above-mentioned assembly hole and through hole structure and rotates freely in the hole structure), and the mounting plate 43 is fastened to the vertical seat body 44 by a plurality of fastening bolts.

[0055] The vertical seat portion 44 is assembled and connected with a vertically arranged horizontal seat portion 2 (in order to further facilitate disassembly, the horizontal seat portion 2 can be plugged into the vertical seat portion 44), and the battery rack is fixedly mounted on the horizontal seat portion 2.

[0056] During the working process, the operator uses a wrench or other tools to screw the screw 42 (in order to facilitate the screwing of the screw 42, a hexagonal groove is opened on the end of the screw 42). At this time, after the screw 42 is rotated, the posture of the pin head 421-locking protrusion 4211 is adjusted from a horizontal state to a vertical state. Due to the change in posture, the locking protrusion 4211 is blocked on the inner side of the locking hole structure 451 in a vertical state. At this time, the battery rack and the shell part are both in a locked state. When the battery rack needs to be disassembled, the pin head 421-locking protrusion 4211 is rotated to a horizontal state. At this time, the battery rack is moved sideways until the pin head 421-locking protrusion 4211 is disengaged from the locking hole structure 451 to achieve unlocking.

[0057] The above method can realize the easy removal of the heavy battery rack with the battery module installed on the load from the frame in an extremely labor-saving and convenient way, and the pin locking method has high stability and is not easy to rust and fall off during use, thus greatly improving the disassembly and assembly efficiency and reducing the difficulty of disassembly and assembly during the replacement and maintenance of the battery rack and battery module.

[0058] Example 2

[0059] like Figure 1-5 As shown, based on the structure of Example 1, since the lock frame beam 1 carries a heavy battery rack, in order to improve its mechanical stability, a plurality of reinforcing plate mechanisms corresponding to the rotating locking mechanism 4 are fixedly connected in the long slot structure. The reinforcing plate mechanism is used to realize internal support to the lock frame beam 1, so as to improve its compressive resistance.

[0060] Specifically, the reinforcing plate mechanism includes reinforcing plates 31 arranged on both sides (at the same time, the inner side of the reinforcing plate 31 is fixedly connected with a connecting rib plate 313, which improves the structural strength of the reinforcing plate 31).

[0061] The shell member is blocked and limited between the reinforcing plates 31. At the same time, the shell member is arranged between the reinforcing plates 31, and the shielding of the reinforcing plates 31 is used to protect the shell member.

[0062] The shape of the reinforcing plate 31 is as follows: the reinforcing plate 31 includes a vertical plate body portion 311 (playing a reinforcing support role) vertically welded in the long trough structure, and the vertical plate body portion 311 is integrally formed with a bent tail plate portion 312; the tail plate portion 312 forms a blocking portion to protect the shell member.

[0063] Specifically, the trailing plate portions 312 of the reinforcing plates 31 at the front and rear sides are bent in opposite directions and arranged to be in an open shape, so as to effectively isolate and protect the housing member.

[0064] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the present invention should also fall within the protection scope of the present invention.
