Description

Technical Field

[0001] The present invention relates to the technical field of electric vehicles, and in particular to a battery box locking device. Background Art

[0002] With the increasing awareness of environmental protection and the advocacy of energy conservation and emission reduction in recent years, the use of gasoline vehicles has become less and less, and the use of new energy vehicles has become more and more popular. New energy vehicles are vigorously promoted because of their environmental protection, fast power response, low noise and light vibration. New energy vehicles are powered by batteries to drive the vehicle. Therefore, the battery life and whether the battery is easy to charge or replace are important indicators that people consider.

[0003] New energy trucks have a heavy load, require a lot of power, and use a large battery capacity. Therefore, it takes a long time to charge the battery of a new energy truck. Therefore, new energy trucks generally use battery replacement to replenish electricity. The battery size and weight of new energy trucks are relatively large, and it is not easy to replace the battery. At the same time, during the driving process of the vehicle, due to the impact of bumps and inertia, the battery often shakes or collides, which can easily damage the battery. In order to prevent the battery from shaking, one or more locking devices are generally required to fix it, but the operation of the locking device is cumbersome, and some locking devices are also prone to getting stuck or locking problems.

[0025] This embodiment discloses a battery box locking device, such as Figure 1 As shown, this may include:

[0026] Frame assembly 10;

[0027] The locking assembly 20 includes a first fixing unit 21, a driving unit 23, a locking unit 24, and a supporting unit 25; one end of the first fixing unit 21 is detachably connected to the frame assembly 10, and the other end is detachably connected to one side of the locking unit 24; the supporting unit 25 is detachably connected to the frame assembly 10, and is arranged on a side of the locking unit 24 away from the first fixing unit 21; the driving unit 23 includes a guide portion 231, a fixing seat 232, and a driving portion 233; the driving portion 233 includes a first driving rod 2331, a second driving rod 2332, and a third driving rod 2333; the fixing seat 232 is detachably connected to the frame assembly 10; one end of the guiding portion 231 is rotatably connected to the fixing seat 232; one end of the first driving rod 2331 is hinged to the guiding portion 231; the second driving rod 2332 is hinged to the first driving rod 2 331 is slidingly connected and slides along the length direction of the first driving rod 2331; the end of the second driving rod 2332 away from the guide part 231 is hinged to one end of the third driving rod 2333; the outer peripheral side of the third driving rod 2333 is threadedly connected to the first fixed unit 21; when the guide part 231 rotates, the third driving rod 2333 is driven to rotate by the first driving rod 2331 and the second driving rod 2332; the third driving rod 2333 rotates to drive the end of the first fixed unit 21 close to the locking unit 24 to move toward or away from the supporting unit 25; the locking device includes a locking state; the locking state includes the third driving rod 2333 driving the distance between the locking unit 24 and the supporting unit 25 to be less than or equal to the first distance; in the locked state, the angle between the second driving rod 2332 and the third driving rod 2333 is less than or equal to the first angle.

[0028] In recent years, new energy vehicles have become more and more popular due to their environmental protection, fast power response, low noise and light vibration. New energy vehicles are powered by batteries to drive the vehicle, which requires the battery to have good endurance. Therefore, the battery needs to be charged or replaced frequently. New energy trucks, due to their large battery size and weight and long charging time, often use battery replacement. Therefore, whether the battery is easy to replace is an important indicator of the performance of new energy trucks. Moreover, during the driving process of the vehicle, the battery often shakes due to the impact of bumpy road conditions and vehicle inertia. In order to prevent the battery from shaking, one or more locking devices are generally required to fix it, but the locking device often has the problem of being stuck, which in turn affects the replacement of the battery.

[0029] In this embodiment, if Figure 1As shown, in order to prevent the battery on the new energy vehicle from shaking, a battery box locking device can be set on the battery box. The battery box locking device may include: a frame assembly 10 and a locking assembly 20. The frame assembly 10 can be connected to the vehicle, so that a separate space can be provided to store the battery and protect the battery. The locking assembly 20 can be set on the frame assembly 10 and detachably connected to the frame assembly 10 to fix the battery and prevent the battery from shaking. Figure 3 As shown, the locking assembly 20 may include a first fixing unit 21, a driving unit 23, a locking unit 24, and a supporting unit 25. The upper end of the first fixing unit 21 is fixed to the frame assembly 10 by bolts, so that the locking assembly 20 can be fixed to the frame assembly 10, providing a fulcrum for the locking assembly 20 during locking or loosening. The lower end of the first fixing unit 21 is detachably connected to the upper side of the locking unit 24, so that the entire locking assembly 20 can be connected to the frame assembly 10 through the first fixing unit 21, and the frame assembly 10 is then connected to the vehicle, thereby preventing the battery from moving relative to the vehicle. The supporting unit 25 is detachably connected to the frame assembly 10, and is used to place and support the battery. As shown Figure 2 As shown, the support unit 25 can be disposed at the lower portion of the frame assembly 10, parallel to the lower edge of the frame assembly 10. The driving unit 23 can drive the locking unit 24 to move up and down, thereby locking and releasing the battery. Figure 3 As shown, the driving unit 23 may include a guide portion 231, a fixing seat 232, and a driving portion 233. The driving portion 233 may be driven to move in the horizontal direction by rotating the guide portion 231, thereby causing the first fixing unit 21 to move, and finally driving the locking unit 24 to move up and down, thereby locking or releasing the battery. The fixing seat 232 may be fixed to the frame assembly 10 by bolts, so as to facilitate replacement of the driving unit 23 after it is damaged. Figure 3 and Figure 4 As shown, the right end of the guide portion 231 can pass through the interior of the fixing seat 232, can rotate inside the fixing seat 232, and can be hinged with the left end of the driving portion 233, thereby driving the driving portion 233 to rotate, and then driving the first fixing unit 21 to move, thereby causing the locking unit 24 to move up and down. Figure 3 and Figure 4As shown, the driving part 233 may include a first driving rod 2331, a second driving rod 2332, and a third driving rod 2333. The first driving rod 2331 may be a hollow tubular structure, which is sleeved on the second driving rod 2332, and the first driving rod 2331 may slide on the second driving rod 2332. The right end of the second driving rod 2332 is hinged to the left end of the third driving rod 2333. The outer peripheral side of the third driving rod 2333 is threadedly connected with the first fixing unit 21. In this way, when the guide part 231 is rotated, the guide part 231 drives the first driving rod 2331 to rotate, and the first driving rod 2331 drives the second driving rod 2332 to rotate, while the second driving rod 2332 can slide in the first driving rod 2331, so that when the position of the third driving rod 2333 is adjusted, the third driving rod 2333 drives the first fixing unit 21 to move. Then the locking unit 24 is pushed up and down to achieve the purpose of locking or releasing the battery. The battery may have a support surface and a locking surface. The support surface is generally the bottom surface, which is placed on the support unit 25, and the locking surface may be the contact surface with the locking unit 24. The first distance is the distance between the battery support surface and the locking surface. When the locking device is in the locked state, the lower surface of the locking unit 24 is in contact with the upper surface of the battery support unit 25 (such as Figure 2 ) is less than or equal to the first distance. This ensures that the battery is locked. In the locked state, the angle between the second drive rod 2332 and the third drive rod 2333 is less than or equal to the first angle. Figure 3 As shown, the angle between the second drive rod 2332 and the third drive rod 2333 is the angle between the left extension lines of the second drive rod 2332 and the third drive rod 2333. If the first angle is set to be small, the angle of inclination of the first drive rod 2331 and the second drive rod 2332 is small, the force in the vertical direction is small, and the loss of force during the transmission process is small. If the first angle is too large, the angle of inclination of the first drive rod 2331 and the second drive rod 2332 is large, and the loss of force during the transmission process is large. When rotating the guide part 231, a lot of force is required to twist the guide part 231. This may cause the locking device to be stuck and unable to rotate, so the first angle can only be set to be small. Therefore, the angle between the second drive rod 2332 and the third drive rod 2333 can be set to be less than or equal to the first angle.

[0030] In another embodiment, if Figure 2 As shown, when the locking device is in a relaxed state, the distance between the lower surface of the locking unit 24 and the upper surface of the battery support unit 25 is greater than the first distance, and at this time there is a gap between the locking unit 24 and the upper surface of the battery, and the battery is in a relaxed state. At this time, the battery 32 can be easily removed.

[0031] In another embodiment, the support unit 25 may include a support portion 251 and a second plug portion 252. The support portion 251 may be configured as a plane for placing the battery 32 and providing support for the battery 32. The second plug portion 252 may be disposed at the bottom of the support portion 251 for fixing the support portion 251.

[0032] In some embodiments, the first angle is 0° to 15°.

[0033] In this embodiment, in order to prevent the first driving rod 2331 and the second driving rod 2332 from being tilted at a large angle due to the first angle being too large, thereby causing the locking device to be stuck and the guide portion 231 to be unable to be twisted, the first angle can be set to 0° to 15°.

[0034] In some embodiments, Figure 3 , Figure 4 and Figure 5 As shown, the locking unit 24 includes a first guide portion 241 and a locking portion 243; the first guide portion 241 includes a first guide seat 2411, a first guide rod 2412, a first sliding portion 2413, and a second guide seat 2414; the first guide seat 2411 is detachably connected to the frame assembly 10; the second guide seat 2414 is detachably connected to the frame assembly 10; one end of the first guide rod 2412 is detachably connected to the first guide seat 2411, and the other end is detachably connected to the second guide seat 2414; the first sliding portion 2413 is slidably connected to the first guide rod 2412; the first sliding portion 2413 moves toward or away from the support unit 25 along the length direction of the first guide rod 2412; the first sliding portion 2413 is detachably connected to the locking portion 243.

[0035] In this embodiment, if Figure 3 , Figure 4 and Figure 5 As shown, the locking unit 24 may include a first guide portion 241 and a locking portion 243. Figure 5 As shown, the first guide portion 241 can be disposed on the left side of the locking assembly 20. Figure 2 As shown, the first guide portion 241 may be located in the space between the side plate 112 and the locking portion 243 to guide the locking portion 243 to move up and down. Figure 5 As shown, the first guide portion 241 may include a first guide seat 2411, a first guide rod 2412, a first sliding portion 2413, and a second guide seat 2414. Figure 3 and Figure 4 As shown, the first guide seat 2411 can be fixed on the frame assembly 10 by bolts. The second guide seat 2414 can be fixed on the frame assembly 10 by bolts. Figure 5As shown, the first guide rod 2412 passes through the first guide seat 2411 and the second guide seat 2414 respectively. The first guide rod 2412 can be interference fit with the first guide seat 2411 and the second guide seat 2414 respectively. Thereby, the first guide rod 2412 is in a vertical direction. The upper end of the first guide rod 2412 can be detachably connected to the first guide seat 2411 by bolts, and the lower end of the first guide rod 2412 can be detachably connected to the second guide seat 2414. In this way, the position of the first guide rod 2412 can be easily adjusted, thereby adjusting the angle of the locking portion 243, so that the locking portion 243 is in closer contact with the battery, thereby achieving a better locking effect. Figure 5 As shown, the first sliding portion 2413 may be a hollow structure, which is sleeved on the first guide rod 2412. The first sliding portion 2413 may slide up and down along the first guide rod 2412. Figure 5 As shown, the right end of the first sliding portion 2413 can be detachably connected to the left end of the locking portion 243. When the first sliding portion 2413 slides up and down along the first guide rod 2412, the locking portion 243 can only move up and down, thereby achieving the purpose of locking and releasing the battery.

[0036] In some embodiments, Figure 3 and Figure 4 As shown, the locking assembly 20 also includes a second fixing unit 22; the second fixing unit 22 is arranged on a side of the first fixing unit 21 away from the guide portion 231; one end of the second fixing unit 22 is detachably connected to the frame assembly 10, and the other end is detachably connected to a side of the locking unit 24; the outer peripheral side of the third driving rod 2333 is threadedly connected to the second fixing unit 22; the third driving rod 2333 rotates to drive the end of the second fixing unit 22 close to the locking unit 24 to move toward or away from the support unit 25.

[0037] In this embodiment, if Figure 3 and Figure 4As shown, the locking assembly 20 may further include a second fixing unit 22. The second fixing unit 22 may be similar to the first fixing unit 21. The second fixing unit 22 may be arranged on the right side of the first fixing unit 21. In this way, the support of the driving unit 23 may be more stable, and the force applied to the locking unit 24 may be more uniform, so as to achieve a better locking effect. One end of the second fixing unit 22 may be detachably connected to the frame assembly 10, and the other end may be detachably connected to one side of the locking unit 24. In this way, the second fixing unit 22 may be fixed to the frame assembly 10, and the driving unit 23 may be moved in the horizontal direction while providing a fulcrum for the second fixing unit 22, thereby driving the locking unit 24 to move up and down, so as to achieve the purpose of locking and releasing the battery. The outer peripheral side of the third driving rod 2333 may be threadedly connected to the second fixing unit 22. The third driving rod 2333 may drive a part of the second fixing unit 22 to move left or right by rotation, thereby driving the locking unit 24 to move up and down, so as to achieve the effect of locking and releasing the battery.

[0038] In some embodiments, Figure 3 and Figure 4 As shown, the locking unit 24 also includes a second guide portion 242; the second guide portion 242 is arranged on a side of the first guide portion 241 away from the guide portion 231; the second guide portion 242 includes a third guide seat 2421, a second guide rod 2422, a second sliding portion 2423, and a fourth guide seat 2424; the third guide seat 2421 is detachably connected to the frame assembly 10; the fourth guide seat 2424 is detachably connected to the frame assembly 10; one end of the second guide rod 2422 is detachably connected to the third guide seat 2421, and the other end is detachably connected to the fourth guide seat 2424; the second sliding portion 2423 is slidably connected to the second guide rod 2422; the second sliding portion 2423 moves along the length direction of the second guide rod 2422 toward or away from the support unit 25; the second sliding portion 2423 is detachably connected to the locking portion 243.

[0039] In this embodiment, if Figure 3 and Figure 4 As shown, the locking unit 24 may further include a second guide portion 242. The second guide portion 242 may have the same structure as the first guide portion 241. The second guide portion 242 is the same as the first guide portion 241 and may be disposed in the space between the side plate 112 and the locking portion 243 to guide the locking portion 243 to move up and down.
