Description

Technical Field

[0001] The present invention belongs to the technical field of battery replacement devices, and specifically relates to a battery replacement structure for a new energy vehicle. Background Art

[0002] New energy vehicle chassis battery replacement technology is a technology that replaces batteries by removing and replacing the battery pack at the bottom of the electric vehicle chassis. This technology has significant advantages, including short battery replacement time and no change in the weight of the front and rear axles of the vehicle body.

[0003] For example, the invention patent application with patent application number 201810921983.0 discloses a battery swap device, which includes: a bottom platform; a battery placement platform above the bottom platform; and a connecting component connecting the bottom platform and the battery placement platform, wherein the connecting component includes an elastic member so that the battery placement platform can be tilted relative to the bottom platform. The structure of the battery swap device can be adaptively adjusted according to the tilt of the bottom of the vehicle.

[0004] Its adaptive adjustment is achieved through the cooperation between the positioning pin and the positioning hole. Specifically, during the lifting process, as the positioning pin is inserted into the inclined positioning hole, the battery placement platform will also adaptively adjust and tilt, thereby being parallel to the bottom plane of the vehicle.

[0005] Although this positioning method can achieve adaptive adjustment, adaptive adjustment is required during the disassembly and assembly process; and during the above-mentioned adaptive adjustment process, the locating pin is inserted into the locating hole at an angle, and then the whole is straightened, which will cause greater resistance between the locating pin and the locating hole, resulting in damage to the locating pin or the locating hole on the vehicle.

[0006] At the same time, a series of rollers are arranged on it for conveying batteries, but during the overall movement of the device, the arrangement of the rollers may cause the batteries to slide randomly and fall off. Summary of the invention

[0007] In response to the above technical problems, the present invention provides a new energy vehicle battery replacement structure, which adopts a planar contact method to adjust and maintain parallelism with the bottom of the vehicle, and only adjusts the angle when disassembling.

[0008] In order to solve the above technical problems, the technical solution adopted by the present invention is: A new energy vehicle battery replacement structure, comprising a bottom plate, a fixed support plate, a movable support plate and an adjustment plate, wherein a walking mechanism is provided on the bottom plate, and the bottom plate is driven to move by the walking mechanism; a lifting mechanism is provided between the fixed support plate and the bottom plate, and the fixed support plate is driven to rise and fall by the lifting mechanism; the movable support plate is connected to the fixed support plate by a ball joint; an elastic support column in contact with the fixed support plate is fixedly connected to the movable support plate; A support column is fixedly connected to the adjustment plate, and the support column is slidably connected to the fixed support plate and extends through the fixed support plate; there are four support columns, each of which is threadedly connected to an adjustment strut, and the top of the adjustment strut is in contact with the lower surface of the movable support plate; a telescopic mechanism is provided between the adjustment plate and the fixed support plate.

[0009] The walking mechanism adopts a wheeled walking mechanism, and the lifting mechanism adopts a scissor-type lifting mechanism.

[0010] The top of the adjusting support rod is hemispherical and a circle of protrusions is arranged on the adjusting support rod.

[0011] The elastic support column includes a fixed column and a movable column. The movable column is slidably connected to the fixed column, and a spring is arranged between the movable column and the fixed column. The fixed column is fixedly connected to the movable support plate, and the lower end of the movable column contacts the fixed support plate.

[0012] The lower end of the movable column is hemispherical; and four elastic support columns are provided.

[0013] A pair of support roller assemblies are fixedly connected to the bottom plate, and the support roller assembly includes a support frame and a support roller. A plurality of support rollers are provided, and the plurality of support rollers are rotatably connected to the upper end of the support frame; the fixed support plate, the movable support plate and the adjustment plate are all provided with through holes that cooperate with the support roller assembly.

[0014] An anti-slip pad is fixedly connected to the upper surface of the movable support plate.

[0015] The telescopic mechanism adopts an electric telescopic rod.

[0016] Compared with the prior art, the present invention has the following beneficial effects: The movable support plate is connected to the middle part of the fixed support plate by a ball joint, so that the movable support plate has a certain degree of freedom, and it can better fit with the bottom of the vehicle, thereby ensuring the parallelism between the movable support plate and the bottom of the vehicle.

[0017] When the movable support plate is fitted to the bottom of the vehicle, the top of each adjusting support rod is made to contact the lower surface of the movable support plate by rotating the adjusting support rod, thereby fixing the tilt angle of the movable support plate.

[0018] After the battery is removed, the lifting mechanism drives the movable support plate and the battery downward; then the telescopic mechanism drives the adjustment support rod downward so that the adjustment support rod does not contact the movable support plate; under the action of the elastic support column, the movable support plate is parallel to the ground, thereby ensuring that the battery is in a horizontal state rather than a tilted state during transportation.

[0019] When the battery is installed again, the adjusting support rod is driven upward by the telescopic mechanism so that the adjusting support rod contacts the movable support plate, thereby changing the angle of the movable support plate to make it parallel to the bottom of the vehicle.

[0020] A support roller assembly is provided, which will not contact the battery during the disassembly and assembly process, thereby preventing the battery from sliding. When the battery needs to be removed from the movable support plate, the battery can be supported by the support roller assembly, and the battery can be easily removed from the movable support plate.

DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0023] like Figure 1-6 As shown, a new energy vehicle battery replacement structure includes a base plate 1, a fixed support plate 2, a movable support plate 3 and an adjustment plate 4. A walking mechanism 5 is provided on the base plate 1. The base plate 1 is driven to move by the walking mechanism 5, so that the overall movement of the structure can be achieved. Specifically, a handle is fixedly connected to the base plate 1, and the handle can be used to promote the overall movement.

[0024] A lifting mechanism 6 is provided between the fixed support plate 2 and the bottom plate 1. The fixed support plate 2 is driven to rise and fall by the lifting mechanism 6. After the fixed support plate 2 is lifted, the vehicle chassis battery is replaced.

[0025] The movable support plate 3 is connected to the middle part of the fixed support plate 2 by a ball joint 7; specifically, a ball socket is provided on the fixed support plate 2, and a corresponding ball head is provided on the movable support plate 3, and the ball joint between the two is realized by the cooperation between the ball head and the ball socket. An elastic support column 8 in contact with the fixed support plate 2 is fixedly connected to the movable support plate 3, and the movable support plate 3 is supported by the elastic support column 8 so that the movable support plate 3 is in a horizontal state when it is not affected by an external tilting force.

[0026] A support column 9 is fixedly connected to the adjustment plate 4, and the support column 9 is slidably connected to the fixed support plate 2, and the support column 9 can extend through the fixed support plate 2; there are four support columns 9, and each support column 9 is threadedly connected with an adjustment support rod 10, and the top of the adjustment support rod 10 can contact the lower surface of the movable support plate 3. By rotating each adjustment support rod 10 to change the extension length of each adjustment support rod 10, the inclination angle of the movable support plate 3 can be changed. A telescopic mechanism 11 is provided between the adjustment plate 4 and the fixed support plate 2, and by extending the telescopic mechanism 11, each adjusted adjustment support rod 10 can be moved down without contacting the movable support plate 3.

[0027] The specific operation process is as follows: the structure is moved as a whole to the bottom of the lifted vehicle through the walking mechanism 5 as needed. First, the fixed support plate 2 and the movable support plate 3 are driven to rise by the lifting mechanism 6 until the movable support plate 3 fits with the bottom of the vehicle; when the bottom of the vehicle is not horizontal, the movable support plate 3 will also change its angle accordingly after fitting with the bottom of the vehicle, and the elastic support column 8 will be elastically deformed. After that, each adjustment strut 10 is rotated to change its extension length (in the initial state, it is fully retracted, and even if the movable support plate 3 is in a horizontal state, it does not contact the adjustment struts 10), so that the top of each adjustment strut 10 can contact the lower surface of the movable support plate 3, that is, the tilted movable support plate 3 is supported by each adjustment strut 10.

[0028] When the battery is separated from the bottom of the vehicle, the fixed support plate 2 and the movable support plate 3 are driven downward by the lifting mechanism 6 until the movable support plate 3 is away from the bottom of the vehicle; then the telescopic mechanism 11 is extended, so that each adjusted adjustment strut 10 can be moved downward without contacting the movable support plate 3. At this time, the elastic support column 8 releases elastic potential energy, so that the movable support plate 3 is in a horizontal state during the battery transportation process. At the same time, in order to prevent the elastic support column 8 from randomly expanding and contracting during the movement of the battery, a pad can be inserted between the movable support plate 3 and the fixed support plate 2.

[0029] When the battery needs to be installed, the entire structure is moved to the bottom of the lifted vehicle through the walking mechanism 5. First, the batteries on the fixed support plate 2 and the movable support plate 3 are driven to rise through the lifting mechanism 6; then, the telescopic mechanism 11 is retracted to move the adjusted adjustment struts 10 upward to contact the movable support plate 3, that is, the angle of the movable support plate 3 is changed by the previously adjusted adjustment struts 10. And because the length of the adjusted adjustment struts 10 remains unchanged, after it is lifted, it can ensure that the inclination angle of the movable support plate 3 is the same as the inclination angle when it was disassembled before. Finally, align the battery installation position of the vehicle chassis, and extend the battery into the bottom of the vehicle chassis through the lifting mechanism 6 for installation.

[0030] Furthermore, the traveling mechanism 5 is preferably a wheeled traveling mechanism, and the lifting mechanism 6 is preferably a scissor-type lifting mechanism.

[0031] Furthermore, the top shape of the adjusting strut 10 is preferably hemispherical, and a circle of protrusions 20 is provided on the adjusting strut 10 , and the adjusting strut 10 can be easily rotated through the circle of protrusions 20 , thereby changing the extension length of each adjusting strut 10 .

[0032] Furthermore, the elastic support column 8 includes a fixed column 12 and a movable column 13, the movable column 13 is slidably connected to the fixed column 12, and a protrusion is provided at the lower end of the movable column 13, and the fixed column 12 is provided with a constriction, so as to ensure that the movable column 13 will not be separated from the fixed column 12 after installation. A spring 14 is provided between the movable column 13 and the fixed column 12; the fixed column 12 is fixedly connected to the movable support plate 3, and the lower end of the movable column 13 is in contact with the fixed support plate 2. When the angle of the movable support plate 3 changes, the spring 14 will be deformed to generate elastic potential energy; when the external force is removed, the elastic potential energy can be released by the spring 14 to reset the movable support plate 3 to a horizontal state.

[0033] Furthermore, the shape of the lower end of the movable column 13 is preferably hemispherical; and there are preferably four elastic support columns 8, although the specific number can be set according to actual conditions.

[0034] Furthermore, after the chassis battery is disassembled, when the chassis battery needs to be removed from the movable support plate 3, the sliding friction between the two causes a large resistance when removing the chassis battery. For this purpose, the following structure is also provided: A pair of support roller assemblies 15 are fixedly connected to the base plate 1, and the support roller assembly 15 includes a support frame 16 and a support roller 17. A plurality of support rollers 17 are provided, and the plurality of support rollers 17 are rotatably connected to the upper end of the support frame 16; the fixed support plate 2, the movable support plate 3 and the adjustment plate 4 are all provided with through holes 18 that cooperate with the support roller assembly 15, and the support roller 17 can pass through the through holes 18 and be located above the movable support plate 3.

[0035] With the above-mentioned structural arrangement, during the disassembly and installation process, the support roller 17 is located below the movable support plate 3, that is, the battery is in a planar contact state with the movable support plate 3. When the battery needs to be removed, the fixed support plate 2 and the movable support plate 3 are driven downward by the lifting mechanism 6, so that the support roller 17 can pass through the through hole 18 and be located above the movable support plate 3 to contact the battery and lift the battery; at this time, the battery and the support roller 17 are in a rolling friction state, that is, the battery can be removed relatively easily.

[0036] Furthermore, in order to prevent the battery from sliding during the removal and installation process, an anti-skid pad 19 is fixedly connected to the upper surface of the movable support plate 3, and the friction between the battery and the anti-skid pad 19 is increased. After the battery is lifted up by the support roller 17, there is a gap between the battery and the anti-skid pad 19.

[0037] Furthermore, the telescopic mechanism 11 preferably adopts an electric telescopic rod, and the number of the electric telescopic rods can be two or more according to actual conditions. The two ends of each electric telescopic rod are fixedly connected to the adjustment plate 4 and the fixed support plate 2 respectively.

[0038] Only the preferred embodiments of the present invention have been described in detail above, but the present invention is not limited to the above embodiments.
