The term "and/or" as used herein includes any and all combinations of one or more of the associated listed items.
Referring to fig. 1 and 3, the present invention provides an anti-vibration energy storage battery 10 for a forklift, comprising: the battery pack comprises a shell 100, a cover body 200, a protection assembly 300 and a plurality of battery cells 400.
The shell 100 is opened on one side, and the cover 200 is used for closing the opening; the protection assembly 300 comprises a support wood board 310, an epoxy baffle 320, a middle pressure-bearing sponge 330 and a plurality of support sponges 340, wherein two ends of the middle pressure-bearing sponge 330 are respectively connected with the support wood board 310 and the epoxy baffle 320, a plurality of electric cores 400 are positioned between the support wood board 310 and the epoxy baffle 320, the electric cores 400 are distributed at intervals along the long side direction of the support wood board 310, and the support sponges 340 are arranged on the epoxy baffle 320 and propped against the cover body 200; a structural adhesive (not shown) is filled between the epoxy spacer 320 and the interior cavity of the housing 100.
Preferably, referring to fig. 2 and 3, the housing 100 is provided with a handle 110. Cover 200 is provided with guard plate 230, and housing 100 is provided with relief groove 120 matching guard plate 230. The guard 230 is used to secure the electrical connector.
Compared with the prior art, the shock-resistant energy storage battery 10 for the forklift has the following advantages:
1. An intermediate pressure-bearing sponge 330 is arranged between the supporting wood board 310 and the epoxy partition board 320, and a supporting sponge 340 is arranged between the epoxy partition board 320 and the cover body 200, and the sponge is used for buffering the internal battery cell 400, absorbing vibration generated in the forklift cargo transporting process and improving the overall shock resistance of the battery.
2. The gap between the epoxy spacer 320 and the housing 100 is filled with structural adhesive, so that the internal battery cell 400 cannot be directly taken out even if the user removes the cover 200, the difficulty of self-replacing the battery cell 400 by the user is improved, and the safety problem caused by self-replacing the battery cell 400 is avoided.
In the above embodiment, the structural adhesive is filled between the epoxy spacer 320 and the inner cavity of the housing 100, so that the epoxy spacer 320 is adhered to the housing 100, and when repairing is performed by a serviceman, the structural adhesive is required to be melted by means of a tool such as a hot air gun, or the structural adhesive is cut off by a cutting tool to take out the internal battery cell 400, so that the disassembly difficulty of the battery cell 400 is increased, and the probability of the user to replace the battery cell 400 by himself is reduced, thereby improving the safety performance of the forklift battery. The battery module aims to enable a user to actively contact a forklift manufacturing party when encountering a battery fault problem, and a professional maintainer performs maintenance operation to avoid a safety problem caused by self-maintenance of the battery, wherein the scheme increases the disassembly difficulty of the battery cell 400 through the structural adhesive, but the user can observe the filling position of the structural adhesive after disassembling the cover body 200 and still has the condition of self-disassembling the battery cell 400; on the other hand, the forklift is more applied to open outdoor scenes such as construction sites, and the like, and the places lack monitoring, so that the risk of losing the battery cell 400 is high, and therefore, how to avoid the battery cell 400 to be disassembled by non-maintenance personnel is a problem to be solved.
In order to solve the above-mentioned problem, referring to fig. 2, a bent edge 210 is provided at the edge of the cover 200, and the bent edge 210 extends into the housing 100 and is locked together by a screw.
Referring to fig. 4, a fastening module 500 is disposed at a position where the bending edge 210 contacts the housing 100, and the fastening module 500 includes a movable plate 510, a first spring 520, a second spring 530, a nut 540, a locking slider 550, a sliding bar 560 (as shown in fig. 7), an unlocking screw 570, and a fastening screw 580 matching the nut 540.
Referring to fig. 4 and 5, the movable plate 510 is located on a side of the bending edge away from the housing 100, the first spring 520 is located between the movable plate 510 and the bending edge 210, and the unlocking screw 570 is threaded with the movable plate 510 after passing through the housing 100 and the bending edge 210. When the unlocking screw 570 is screwed down, the movable plate 510 is tightly attached to the bending edge 210 (as shown in fig. 5); after the unlocking screw 570 is removed, the first spring 520 provides an elastic force to jack up the movable plate 510 (as shown in fig. 6).
Referring to fig. 5 and 9, in order to ensure structural stability, in one embodiment, a blocking protrusion 220 is provided on the cover 200, the blocking protrusion 220 is located on a moving track of the movable plate 510, and after the movable plate 510 is jacked up, the movable plate 510 is blocked by the blocking protrusion 220, and the movement range of the movable plate 510 is limited by the blocking protrusion 220; in another embodiment, the bent edge 210 is provided with a limiting pin 214 (as shown in fig. 5 and 6), the limiting pin 214 penetrates through the movable plate 510 and the first spring 520, and the limiting pin 214 provides guiding to prevent the movable plate 510 from shaking when moving.
Referring to fig. 7 and 13, a chute 211, a through hole 212 for accommodating a nut 540, and a limiting groove 213 for accommodating a locking slider 550 are formed on the bent edge 210, two ends of the limiting groove 213 are respectively communicated with the through hole 212 and the chute 211, an extending direction of the chute 211 is perpendicular to an extending direction of the limiting groove 213, one end of a sliding bar 560 is rotatably disposed on the movable plate 510, the other end of the sliding bar 560 is disposed in the chute 211, and preferably, a pulley 561 is disposed on one side of the sliding bar 560 located in the chute 211.
The second spring 530 is used to urge the lock slide 550 closer to the nut 540. I.e., the locking slider 550 is located between the nut 540 and the sliding bar 560, and the second spring 530 provides an elastic force to keep the locking slider 550 in contact with the nut 540 and located at a side close to the nut 540 without being subjected to an external force.
Referring to fig. 5 and 6, the fastening screw 580 passes through the housing 100 and is screwed with the nut 540, the outer side of the nut 540 is provided with external teeth 541, the locking slider 550 is provided with profiling teeth 551 meshed with the external teeth 541, and the external teeth 541 are provided with a stop surface 51 and an inclined surface 52 (as shown in fig. 12).
Referring to fig. 8 and 12, when a maintenance person tightens the fastening screw 580 (as shown by the arrow direction in fig. 8), a torsion force is generated to make the stop surface 51 abut against the tooth surface of the profiling tooth 551, and at this time, the nut 540 is locked by the profiling tooth 551 and cannot rotate, and the fastening screw 580 rotates relative to the nut 540, so as to lock the fastening screw 580;
Referring to fig. 7 and 11, when the maintenance personnel rotates the fastening screw 580 reversely (as shown by arrow direction in fig. 7), the generated torsion force makes the inclined surface 52 abut against the tooth surface of the profiling tooth 551, and at this time, the contact position of the inclined surface 52 and the profiling tooth 551 generates a component force parallel to the limiting groove 213, so that the locking slider 550 slides towards the side of the sliding bar 560 (i.e. the direction away from the nut 540), the nut 540 rotates along with the fastening screw 580, and the threaded connection between the nut 540 and the fastening screw 580 is maintained in this state. That is, the nut 540, the locking slider 550 and the second spring 530 cooperate together to form a ratchet structure, so that the nut 540 can rotate only in one direction.
It should be emphasized that the extending direction of the sliding slot 211 is perpendicular to the extending direction of the limiting slot 213, and the sliding slot 211 is communicated with the limiting slot 213, when the movable plate 510 approaches to or departs from the bent edge 210, the sliding bar 560 swings, so that the sliding bar 560 enters or leaves the sliding track of the locking slider 550, and when the sliding bar 560 is located outside the sliding track of the locking slider 550 (as shown in fig. 9), the locking slider 550 can slide in the limiting slot 213; when the slide bar 560 is located within the sliding track of the lock slider 550 (as shown in fig. 10), the lock slider 550 is blocked from sliding by the slide bar 560.
The fastening module 500 prevents non-maintenance personnel from disassembling the cell 400 as follows:
The screw cap structure of the fastening screw 580 and the unlocking screw 570 is identical, and when the cover 200 is fixed to the housing 100, only the position of the screw cap is visible from the outside, so that the fastening screw 580 and the unlocking screw 570 cannot be distinguished from each other from the external appearance by a non-maintenance person;
Because the fastening screw 580 and the unlocking screw 570 are both in the tightened state, the movable plate 510 and the bending edge 210 are tightly attached together, at this time, the distance between the movable plate 510 and the bending edge 210 is small, and the two ends of the sliding bar 560 are respectively located on the movable plate 510 and the bending edge 210 (one end is rotationally connected with the movable plate 510, and the other end is located in the sliding slot 211), so that the sliding bar 560 is inclined, and one end located in the sliding slot 211 is far away from the center of the sliding slot 211 (i.e. the locking slider 550 is not blocked, as shown in fig. 9 and 11).
At this time, the fastening screw 580 is turned, and the threaded connection between the fastening screw 580 and the nut 540 cannot be released, and the specific principle is as follows: the torsion generated by the rotation of the fastening screw 580 makes the inclined surface 52 prop against the tooth surface of the profiling tooth 551, at this time, the contact position of the inclined surface 52 and the profiling tooth 551 generates a component force parallel to the limiting groove 213, so that the locking slider 550 slides towards the side of the sliding bar 560 (i.e. away from the nut 540), that is, the locking slider 550 cannot block the rotation of the nut 540, and the nut 540 can rotate synchronously with the fastening screw 580, so that the threaded connection between the nut 540 and the fastening screw 580 is maintained, and the cover 200 is prevented from being detached.
The cover 200 is removed as follows:
Maintenance personnel can obtain a maintenance manual of the forklift battery, and can check the distribution positions of the unlocking screw 570 and the fastening screw 580 on the maintenance manual;
First, the distribution position of the unlocking screw 570 is confirmed, and the unlocking screw 570 is removed. Since the unlocking screw 570 passes through the casing 100 and the bending edge 210 and is in threaded connection with the movable plate 510, the movable plate 510 can be unlocked by directly rotating the unlocking screw 570;
after the unlocking screw 570 is separated from the movable plate 510, the movable plate 510 is jacked up by the first spring 520, at this time, the distance between the movable plate 510 and the bending edge 210 is increased, and a pulling force is generated to drag the sliding baffle 560, and the sliding baffle 560 swings around the connection point of the sliding baffle 560 and the movable plate 510 under the action of the pulling force, so that one end of the sliding baffle 560 located in the sliding slot 211 slides to the rear of the locking slide block 550 (as shown in fig. 10 and 11), at this time, the sliding baffle 560 blocks the locking slide block 550, and the locking slide block 550 is locked;
then, the fastening screw 580 is rotated, and at this time, the component force of the contact position of the inclined surface 52 and the profiling tooth 551 cannot push the locking slide 550 to slide, that is, the nut 540 is locked at this time, the fastening screw 580 can be loosened normally by a maintainer, and the cover 200 can be detached after the fastening screw 580 and the unlocking screw 570 are removed.
It should be noted that, the nut 540, the locking slider 550 and the second spring 530 cooperate together to form a ratchet structure, so that the nut 540 can rotate only in one direction. The locking slider 550 is slid only when the threaded connection between the fastening screw 580 and the nut 540 is released, and when the maintenance person tightens the fastening screw 580 after the maintenance operation is completed, the stop surface 51 on the external teeth 541 abuts against the tooth surface of the profile modeling tooth 551 to lock the nut 540, and the fastening screw 580 can be tightened smoothly. That is, the locking operation of the screw does not have to distinguish between the unlocking screw 570 and the fastening screw 580, thereby improving the installation efficiency of the cover 200.
The above embodiment has the following advantageous effects:
1. Since the cover 200 must be removed first, the fastening screw 580 must be removed to remove the unlocking screw 570. The nut parts on the unlocking screw 570 and the fastening screw 580 are the same, and the unlocking screw 570 and the fastening screw 580 cannot be distinguished from the appearance, so that a non-maintainer cannot know which screw should be screwed first, only a maintainer of a forklift battery producer can know the distribution positions of the unlocking screw 570 and the fastening screw 580, and the probability of the battery cell 400 being taken out at will is further reduced;
2. The nut 540 rotates synchronously with the unlocking screw 570 when the non-maintainer screws the same, so as to generate the false impression of 'sliding teeth' of the screw, thereby eliminating the concept of disassembling the battery cell 400, avoiding the user from replacing the battery cell 400 by himself, improving the safety performance of the battery, preventing the battery cell 400 from being taken away by an external person, and reducing the loss probability of the battery cell 400.
Preferably, a plurality of sliding bars 560 are provided, and the sliding bars 560 are grouped in pairs, and two sliding bars 560 in the same group extend into the same chute 211. The movable plate 510 is provided with a plug block 511 (as shown in fig. 4), and two sliding levers 560 in the same group are rotatably provided on the plug block 511. When the movable plate 510 approaches (or moves away from) the bending edge 210, the two sliding rods 560 in the same group move away (or move close) from each other, so that the stress of the movable plate 510 is more balanced, and the movable plate 510 is prevented from being blocked due to deflection during movement.
The above examples illustrate only a few embodiments of the invention, which are described in detail and are not to be construed as limiting the scope of the invention.
