Description

Technical Field

[0001] The invention relates to the technical field of new energy vehicles, and in particular to a remotely controllable battery box quick release device. Background Art

[0002] In recent years, the number of electric vehicles has been increasing. Currently, most electric vehicle battery boxes (including batteries) are fixed with bolts. Once there is a problem with the battery, it is difficult for people to get close due to high temperature smoke and fire that produces toxic gases. Even the whole vehicle may be scrapped due to problems with the battery box. At the same time, this installation method is not convenient for daily maintenance, so it is necessary to develop a battery box installation structure that can achieve quick release. For example, the Chinese invention patent with publication number CN107994178A describes this situation. The current patent structure of the quick release device is a manual device. Once the battery box has special conditions such as rapid fire, the time required from the driver leaving the driving seat to getting off the car with special tools, opening the battery compartment door and starting to remove the battery box is still relatively long, and the fire cannot be controlled in time.

DETAILED DESCRIPTION

[0026] The embodiment of the present invention provides a remotely controllable battery box quick release device, such as Figure 1-7 As shown, it includes a battery box 1, an upper bracket 2, a lower bracket 3, a locking mechanism 4, an actuator 5, and a cylinder 6.

[0027] like Figure 1 As shown, the battery box 1 is fixedly mounted on the upper bracket 2, and the lower bracket 3 is fixed on the vehicle carrier.

[0028] like Figure 3 As shown, the upper bracket 2 and the lower bracket 3 are connected by transverse sliding through a sliding assembly, and the sliding assembly includes guide rails 8 arranged transversely on both sides of the lower bracket 3. Sliders that can slide on the guide rails 8 are arranged on both sides of the upper bracket 2. The slides are L-shaped and surrounded by the guide rails 8. Guide wheels 9 are arranged on the slides, and the guide wheels 9 are slidably adapted to the bottom surface of the guide rails 8.

[0029] In order to facilitate the upper bracket 2 to slide on the lower bracket 3, the lower bracket 3 is provided with pulleys 16 along the lateral direction thereof, and the pulleys 16 are slidably adapted to the bottom surface of the upper bracket 2. The pulleys 16 are used to support the upper bracket 2 and reduce the friction between the upper bracket 2 and the lower bracket 3.

[0030] The locking mechanism 4 is arranged on the lower bracket 3 , and the actuator 5 is arranged on the upper bracket 2 . When the upper bracket 2 slides into the lower bracket 3 laterally, the locking mechanism 4 can lock the actuator 5 .

[0031] like Figure 3 As shown, the cylinder 6 is arranged on the lower bracket 3 , and the extrusion head 7 on the output end of the cylinder 6 corresponds to the actuator 5 . The extrusion head 7 can laterally squeeze the actuator 5 to push the upper bracket 2 away from the lower bracket 3 .

[0032] Specifically, Figure 3 and Figure 4 As shown, the actuator 5 includes an unlocking body 51, a guide slide 54, a fixed post 55 and a second spring 56. The end of the unlocking body 51 corresponding to the extrusion head 7 is the inner end, and the end away from the extrusion head 7 is the outer end. The outer ends of the unlocking body 51 are provided with limiting bevels 52 for being limited by the locking mechanism 4 on both sides, and the spacing between the limiting bevels 52 on both sides is smaller outside and larger inside. The extrusion head 7 corresponds to the inner end of the unlocking body 51. The unlocking body 51 body is not fixedly connected to the upper bracket 2. Two guide slide grooves 53 are provided on the unlocking body 51, and the two guide slide grooves 53 are arranged side by side. A guide slide 54 is slidably adapted in each guide slide groove 53, and the guide slide 54 is fixed on the upper bracket 2, and the fixed post 55 is fixed on the unlocking body 51. The second spring 56 connects the guide slide 54 and the fixed post 55. By providing the second spring 56, the unlocking body 51 has a tension in the inner direction to prevent the unlocking body 51 from automatically sliding to the outer end.

[0033] like Figure 4 and 6As shown, the locking mechanism 4 includes two groups of card rods 40 and two groups of locking assemblies, the two groups of card rods 40 are arranged on the upper bracket 2, and the two groups of locking assemblies are arranged on the lower bracket 3. The two groups of card rods 40 and the locking assemblies are symmetrically arranged on both sides of the unlocking body 51. The locking assembly includes a shell 41, a lock hook body 42, and a lock tongue body 44. The shell 41 is fixed on the lower bracket 3, and the lock hook body 42 and the lock tongue body 44 are rotatably connected to the shell 41. The lock tongue body 44 is provided with a lock tongue rear hook 45 and a lock tongue front hook 46. The end of the lock hook body 42 is provided with a limiting hook 43 that can hook the lock tongue rear hook 45 or the lock tongue front hook 46. The lock tongue body 44 is located between the lock tongue rear hook 45 and the lock tongue front hook 46 for the card rod 40 to be inserted into the groove 47. The rotating shafts of the lock hook body 42 and the lock tongue body 44 are sleeved with a torsion spring, and the two ends of the torsion spring abut against the fixed carrier. Under normal conditions, the lock hook body 42 and the lock tongue body 44 are as follows: Figure 6 In the state shown, the groove 47 faces the latching rod 40 on the upper bracket 2 .

[0034] When the upper bracket 2 slides into the lower bracket 3 laterally, the latch rod 40 at the bottom of the upper bracket 2 gradually enters the groove 47 and drives the lock tongue body 44 to rotate until the lock tongue front hook 46 is hooked on the limit hook 43, thus completing the locking of the upper bracket 2.

[0035] like Figure 6 As shown, a micro switch 17 is also provided on the housing 41. When the limit hook 43 hooks the front hook 46 of the lock tongue, the rear hook 45 of the lock tongue contacts the micro switch 17. The micro switch 17 is electrically connected to a monitoring device, which may be an indicator light or other device, and is not specifically limited thereto. It is used to transmit a signal that the limit hook 43 locks the front hook 46 of the lock tongue.

[0036] The locking mechanism 4 further includes two sets of unlocking rods 48, which are symmetrically arranged on both sides of the unlocking body 51 and are laterally slidably adapted on the lower bracket 3. The unlocking rods 48 are linked with the lock hook body 42. Specifically, a sliding shaft is fixed on the lock hook body 42, and a groove body is provided on the unlocking rod 48 for the sliding shaft to move. The width of the groove body is greater than the diameter of the sliding shaft. When the unlocking rod 48 moves laterally, the lock hook body 42 can be linked to rotate. A roller 49 is provided at one end of the unlocking rod 48 that contacts the unlocking body 51.

[0037] like Figure 7 As shown, when the front hook 46 of the lock tongue is hooked on the limiting hook 43, the roller 49 at the end of the unlocking rod 48 is located on the limiting bevel 52 of the unlocking body 51. The lateral displacement of the unlocking body 51 is limited by the unlocking rod 48, thereby limiting the lateral displacement of the upper bracket 2.

[0038] The device also includes two sets of auxiliary reset components, which include a push rod 10 and a push block 13. Slide holes 11 are provided on both sides of the lower bracket 3 for the push rod 10 to slide horizontally. A spring 12 is sleeved on the push rod 10. The push block 13 is arranged on the upper bracket 2 and corresponds to the end of the push rod 10. When the upper bracket 2 slides into the lower bracket 3 until the front hook 46 of the lock tongue is hooked on the limit hook 43, the push block 13 on the upper bracket 2 will squeeze the push rod 10 for a certain distance and compress the spring 12. The tension of the spring 12 is not enough to push open the front hook 46 of the lock tongue and the limit hook 43. When the cylinder 6 pushes open the unlocking body 51 until the front hook 46 of the lock tongue is separated from the limit hook 43, the auxiliary reset component can assist the upper bracket 2 to continue to pop open until it is separated from the lower bracket 3.

[0039] The front and rear ends of the upper bracket 2 are respectively provided with a positioning column 14 and a positioning column 2 15, and the lower bracket 3 is provided with a limit block for limiting the positioning column 14 and the positioning column 2 15. When the limit hook 43 hooks the front hook 46 of the lock tongue, the positioning column 14 and the positioning column 2 15 contact the limit block.

[0040] Working principle: When the vehicle battery box has a fire or other faults, the control system controls the cylinder 6 to quickly push the extrusion head 7, so that the unlocking body 51 moves toward the outer end, and the limit bevel 52 of the unlocking body 51 gradually pushes the unlocking rod 48, and the lock hook body 42 is linked to rotate. At the same time, the clamping rod 40 also moves outward with the upper bracket 2 until the limit hook 43 is separated from the front hook 46 and the rear hook 45 of the lock tongue in turn, and the clamping rod 40 is separated from the groove 47, and the unlocking is completed. With the assistance of the push rod 10, the upper bracket 2 is pushed out of the lower bracket 3, and the battery box 1 is quickly released with one button. When the control system and the cylinder 6 fail, the invention can still realize the manual pulling of the unlocking body 51 to achieve the quick release function.

[0041] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
