Description

Technical Field

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

[0002] The vehicle chassis battery swap device is the core component of the electric vehicle battery swap station, which is mainly responsible for the rapid replacement of battery packs. In addition, the battery swap platform adopts a layered architecture to meet the needs of different levels of applications, and integrates automation equipment and safety monitoring systems to improve the efficiency and safety of battery swaps. Together, these components ensure that the battery swap platform can provide efficient and safe battery replacement services for electric vehicles.

[0003] For example, patent application number 202310158566.6 discloses a battery swapping platform and a charging and swapping station, in which a first lifting device and a second lifting device are arranged on both sides of the front wheel positioning device and the rear wheel positioning device along the width direction of the platform, without occupying the space below the front wheel positioning device and the rear wheel positioning device. This also greatly reduces the height of the platform body, which is conducive to the vehicle to enter the battery swapping platform more conveniently and smoothly, thereby improving the user's battery swapping experience.

[0004] The front wheel alignment device uses a V-shaped roller arrangement to form a pit, the purpose of which is to limit the movement of the front wheel, thereby limiting the movement of the vehicle. After the vehicle is replaced, it needs to overcome the obstacles in the process of driving out of the pit; moreover, when the rear wheel passes through the pit, it will be bumpy, thus affecting the user's battery replacement experience.

[0005] At the same time, when the vehicle is positioned by the front wheel and rear wheel positioning devices, the push plate directly contacts the tires, thereby pushing the vehicle to move on the rollers to achieve positioning. The above driving method causes a sense of frustration when the vehicle is pushed, reducing the comfort of the occupants. Summary of the invention

[0007] In order to solve the above technical problems, the technical solution adopted by the present invention is: A new energy vehicle chassis battery replacement device, comprising a base plate platform, a front wheel positioning device and a rear wheel positioning device; the front wheel positioning device and the rear wheel positioning device are both fixed on the base plate platform; the front wheel positioning device comprises a jacking assembly, a support frame and a pair of oppositely arranged inclined roller assemblies, the inclined roller assembly comprises a positioning push plate, an inclined roller bracket, a fixed inclined roller and a movable inclined roller; the fixed inclined roller and the movable inclined roller are both provided with a plurality of them, and the fixed inclined roller and the movable inclined roller are arranged in an X-shaped staggered manner; the two ends of the fixed inclined roller are respectively rotatably connected to the two sides of the inclined roller bracket, one side of the inclined roller bracket is hinged with a swing frame, and the other side of the inclined roller bracket is provided with an arc groove, the arc groove is slidably connected with a movable frame, and the two ends of the movable inclined roller are respectively rotatably connected to the swing frame and the movable frame; The jacking assemblies are provided with two, and the two jacking assemblies are respectively located on both sides of the support frame, and each inclined roller assembly corresponds to a jacking assembly; the support frame is jacked up by the two jacking assemblies or the movable frame in the corresponding inclined roller assembly is pushed by the jacking assemblies to move along the arc groove; The positioning push plates in the two inclined roller assemblies are both slidably connected to the support frame. A first driving assembly is arranged in the support frame, and the positioning push plates in the two inclined roller assemblies are driven by the first driving assembly to move relative to or away from each other.

[0008] At least one fixed oblique roller located on the outside of the oblique roller assembly is fixedly connected to a first driving gear, and a first driving rack meshing with the first driving gear is fixed on the positioning push plate. When the positioning push plate and the first driving rack move, the corresponding fixed oblique roller is driven to rotate.

[0009] The support frame is fixedly connected with a first connecting plate, and the movable frame is fixedly connected with a second connecting plate; the lifting assembly includes a base and a slide, and the slide is fixedly connected with a first telescopic cylinder; the slide is slidably connected to the base; the movement of the slide drives the first telescopic cylinder to be located below the first connecting plate or the second connecting plate.

[0010] A return spring is arranged between the base and the slide, a push rod is fixedly connected to the slide, and the positioning push plate contacts the push rod to push the slide to move.

[0011] The first driving assembly includes a driving motor and a forward and reverse screw; the forward and reverse screw is rotatably connected to the support frame, and the positioning push plates in the two inclined roller assemblies are both threadedly connected to the forward and reverse screw; the outer shell of the driving motor is fixedly connected to the support frame, and the forward and reverse screw is driven to rotate by the driving motor.

[0012] The rear wheel positioning device comprises a rear wheel positioning frame, support rollers and a rear wheel push plate; a plurality of rotatable support rollers are provided on both sides of the rear wheel positioning frame; two rear wheel push plates are provided and are respectively slidably connected to the two sides of the rear wheel positioning frame; a second drive assembly is provided between the two rear wheel push plates, and the two rear wheel push plates are driven to move relative to or away from each other by the second drive assembly.

DETAILED DESCRIPTION

[0020] 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.

[0021] like Figure 1-11 As shown, a new energy vehicle chassis battery replacement device includes a base plate platform 1, a front wheel positioning device 2 and a rear wheel positioning device 3; the front wheel positioning device 2 and the rear wheel positioning device 3 are both fixed on the base plate platform 1.

[0022] The front wheel positioning device 2 includes a lifting assembly 20, a support frame 21 and a pair of inclined roller assemblies 22 arranged relatively in the support frame 21. The inclined roller assembly 22 includes a positioning push plate 220, an inclined roller bracket 221, a fixed inclined roller 222 and a movable inclined roller 223; a plurality of fixed inclined rollers 222 and movable inclined rollers 223 are provided, and the fixed inclined rollers 222 and movable inclined rollers 223 are arranged in an X-shaped staggered manner; both ends of the fixed inclined roller 222 are rotatably connected to the two sides of the inclined roller bracket 221, that is, the inclination angle of the fixed inclined roller 222 is fixed.

[0023] A swing frame 224 is hinged on one side of the inclined roller bracket 221, and an arc groove 226 is provided on the other side of the inclined roller bracket 221. The arc groove 226 is slidably connected to a movable frame 225. The movable frame 225 is provided with a corresponding connecting shaft, and each movable frame 225 is connected through the connecting shaft. The two ends of the movable inclined roller 223 are rotatably connected to the swing frame 224 and the movable frame 225 respectively. By pushing the connecting shaft to move in the arc groove 226, the movable frame 225, the movable inclined roller 223 and the swing frame 224 are driven to move, thereby changing the inclination angle of the movable inclined roller 223.

[0024] Specifically, two jacking assemblies 20 are provided, and the two jacking assemblies 20 are respectively located on both sides of the support frame 21, and the support frame 21 is jacked up by the two jacking assemblies 20. Thus, the vehicle located on the front wheel positioning device 2 is jacked up to replace the chassis battery. The support frame 21 is slidably connected to the bottom plate platform 1.

[0025] Furthermore, each inclined roller assembly 22 corresponds to a lifting assembly 20 , and the lifting assembly 20 pushes the movable frame 225 in the corresponding inclined roller assembly 22 to move along the arc groove 226 , thereby changing the inclination angle of the movable inclined roller 223 .

[0026] The positioning push plates 220 in the two inclined roller assemblies 22 are both slidably connected to the support frame 21. A first driving assembly 23 is provided in the support frame 21. The first driving assembly 23 drives the positioning push plates 220 in the two inclined roller assemblies 22 to move relative to or away from each other; that is, the front wheels of the vehicle located on the inclined roller assemblies 22 can be pushed / clamped.

[0027] When the chassis battery needs to be replaced, the first drive assembly 23 drives the positioning push plates 220 in the two inclined roller assemblies 22 to move relative to each other, thereby pushing the front wheels of the vehicle located on the inclined roller assemblies 22 to move; the rear wheel positioning device 3 operates synchronously to drive the rear wheels of the vehicle located on the rear wheel positioning device 3 to move, thereby realizing the overall mobile positioning of the vehicle.

[0028] After the chassis battery is replaced, the first drive assembly 23 drives the positioning push plates 220 in the two inclined roller assemblies 22 to move in opposite directions; the rear wheel positioning device 3 operates synchronously, that is, the front and rear wheels of the vehicle are not clamped. At this time, the movable frame 225 in the corresponding inclined roller assembly 22 is pushed by the jacking assembly 20 to move along the arc groove 226, reducing the inclination angle between the movable inclined roller 223 and the ground, and jacking up the front wheel of the vehicle; that is, the depth of the groove formed between the movable inclined roller 223 and the fixed inclined roller 222 is reduced. At this time, the vehicle can easily drive away from the front wheel positioning device 2, reducing the resistance, ensuring that the vehicle can pass smoothly, and improving the comfort of the vehicle when passing.

[0029] Furthermore, when the positioning push plate 220 contacts the front wheel of the vehicle and pushes the front of the vehicle to move, since the positioning push plate 220 contacts the tire and the tire is connected to a shock-absorbing component, the vehicle body will shake during the initial pushing process, which will also reduce the comfort of the occupants. To this end, the battery replacement device adopts the following structural settings: A first driving gear 227 is fixedly connected to at least one fixed skew roller 222 located on the outside of the skew roller assembly 22, that is, only some of the fixed skew rollers 222 are provided with the first driving gear 227. A first driving rack 228 meshing with the first driving gear 227 is fixed to the positioning push plate 220, and the movement of the positioning push plate 220 and the first driving rack 228 drives the fixed skew rollers 222 located on the outside to rotate.

[0030] When the chassis needs to be replaced, the first drive rack 228 moves and meshes with the corresponding first drive gear 227 through the movement of the positioning push plate 220 to drive the corresponding fixed inclined roller 222 to rotate, and the fixed inclined roller 222 will drive the wheels thereon to move when it rotates; as the positioning push plate 220 moves, until it moves to the fixed inclined roller 222 where the first drive gear 227 is not provided, the front wheels of the vehicle are clamped and fixed. In the above initial pushing process, the movement of the vehicle is driven by the rotation of the fixed inclined roller 222, so the shaking of the vehicle can be reduced to a large extent, and the comfort of the occupants can be improved.

[0031] Furthermore, first connecting plates 229 are fixedly connected to both sides of the support frame 21, and the movable frame 225 is fixedly connected to a second connecting plate 2210; the lifting assembly 20 includes a base 200 and a slide 201, and a first telescopic cylinder 202 is fixedly connected to the slide 201; the slide 201 is slidably connected to the base 200. The base 200 is fixedly connected to the bottom plate platform 1.

[0032] When the chassis needs to be replaced, the carriage 201 moves and drives the first telescopic cylinder 202 to be located below the first connecting plate 229, and the support frame 21 and the front part of the vehicle located on the support frame 21 are lifted up by the first telescopic cylinder 202 to replace the chassis. When the vehicle is replaced, the carriage 201 moves and drives the first telescopic cylinder 202 to be located below the second connecting plate 2210, and the movable frame 225 is lifted up by the first telescopic cylinder 202, thereby reducing the inclination angle between the movable inclined roller 223 and the ground.

[0033] Furthermore, a return spring 203 is provided between the base 200 and the slide 201, and both ends of the return spring 203 are fixedly connected to the base 200 and the slide 201 respectively; a push rod 204 is fixedly connected to the slide 201, and the positioning push plate 220 contacts the push rod 204 to push the slide 201 to move.

[0034] During the battery replacement process, the two positioning push plates 220 move toward the middle, that is, each positioning push plate 220 does not contact the corresponding push rod 204, and under the action of the reset spring 203, the first telescopic cylinder 202 is located below the first connecting plate 229. When the battery replacement is completed, the two positioning push plates 220 move outward, and each positioning push plate 220 contacts the corresponding push rod 204 to push the slide 201 to move, so that the first telescopic cylinder 202 is located below the second connecting plate 2210, and the reset spring 203 generates elastic potential energy. That is, the above-mentioned structural setting can realize the adaptive movement of the position of the first telescopic cylinder 202 during and after the battery replacement.

[0035] Furthermore, two first telescopic cylinders 202 are fixedly connected to the slide 201, and two first connecting plates 229 are fixedly connected to both sides of the support frame 21. The first telescopic cylinder 202 near the movable frame 225 cooperates with the second connecting plate 2210 to lift the movable frame 225.

[0036] Furthermore, the first driving assembly 23 includes a driving motor 230 and a forward and reverse screw 231; the forward and reverse screw 231 is rotatably connected to the support frame 21, and the positioning push plates 220 in the two inclined roller assemblies 22 are both threadedly connected to the forward and reverse screws 231 (a corresponding nut is fixed on each positioning push plate 220); the housing of the driving motor 230 is fixedly connected to the support frame 21, and the forward and reverse screws 231 are driven to rotate by the driving motor 230, and the driving motor 230 and the forward and reverse screws 231 can be connected by transmission means such as gears.

[0037] Furthermore, the rear wheel positioning device 3 can adopt a common structural setting in the prior art, which includes a rear wheel positioning frame 30, a support roller 31 and a rear wheel push plate 32; a plurality of rotatable support rollers 31 are provided on both sides of the rear wheel positioning frame 30; two rear wheel push plates 32 are provided and are respectively slidably connected to the two sides of the rear wheel positioning frame 30; a second drive component 33 is provided between the two rear wheel push plates 32, and the two rear wheel push plates 32 are driven to move relative to or away from each other by the second drive component 33. As above, the second drive component 33 can be driven by a screw nut. A second telescopic cylinder 36 is fixedly connected between the rear wheel positioning frame 30 and the bottom plate platform 1, and the rear wheel positioning frame 30 is lifted up by the second telescopic cylinder 36.

[0038] As above, in order to further reduce the shaking of the vehicle during the initial pushing process, the rear wheel positioning device 3 is also set up in the same principle as the above-mentioned front wheel positioning device 2. That is, a second drive gear 34 is provided on the support roller 31 located on the outside of the support roller 31, and the corresponding second drive rack 35 meshing with the second drive gear 34 is fixed on the two rear wheel push plates 32. The operation principle of the two is the same, that is: when the chassis needs to be replaced, the second drive rack 35 moves and meshes with the corresponding second drive gear 34 through the movement of the rear wheel push plate 32, driving the corresponding support roller 31 to rotate, and when the support roller 31 rotates, it will drive the wheel on it to move; as the rear wheel push plate 32 moves, until it moves to the support roller 31 where the second drive gear 34 is not provided, the rear wheel of the vehicle is clamped and fixed.

[0039] Furthermore, in order to protect the tire of the vehicle, a rubber plate is fixedly connected to the inner side of the positioning push plate 220, that is, the positioning push plate 220 is in contact with the tire (wheel) through the rubber plate.

[0040] 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.
