[0030] With reference to the accompanying drawings, the technical solutions in the embodiments of the present application will be described clearly and completely. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments of the present application, all the other embodiments obtained by those skilled in the art without creative efforts are within the scope of the present application.

[0031] The utility model discloses a kind of battery swap station opening and closing door mechanism and battery swap station, to simplify overall structure, improve carrying capacity and battery swap efficiency.

[0032] In order to make the above-mentioned purposes, features and advantages of the present application more apparent, easy to understand, the present application will be further described in detail below with reference to the drawings and specific embodiments.

[0033] With reference to Figures 1-6 The embodiment provides a kind of battery swap station opening and closing door mechanism 100, including opening and closing door fixed frame, opening and closing door moving plate 1 and opening and closing door mechanism.

[0034] Opening and closing door fixed frame is used to be installed above tunnel, and opening and closing door fixed frame is equipped with door closing position.Opening and closing door moving plate 1 is installed on opening and closing door fixed frame, and can reach and leave door closing position by the way of displacement.Opening and closing door mechanism is installed on opening and closing door fixed frame, for driving opening and closing door moving plate 1 displacement.

[0035] The working principle of the battery swap station opening and closing door mechanism 100 of the embodiment is as follows:

[0036] The embodiment does not use the mode of lifting electric vehicle to replace battery, but sets tunnel below vehicle battery replacement position, and battery replacement equipment 600 is located in tunnel.Before vehicle drives to battery replacement position, opening and closing door moving plate 1 is in door closing position.After vehicle drives to battery replacement position, vehicle front wheel has driven through door closing position, and the battery pack of vehicle is located just above door closing position, at this time, opening and closing door mechanism removes opening and closing door moving plate 1 from door closing position, and battery replacement equipment 600 extends upward from tunnel, and battery replacement is realized by subsequent operation.

[0037] The above-mentioned battery replacement process does not need to set lifting device, simplifies the structure of battery swap station, and reduces the construction cost of battery swap station.In addition, since the vehicle lifting process is saved, the owner and passenger can complete battery replacement without getting off the vehicle, improve user experience and battery replacement efficiency.

[0038] As a possible example, in the embodiment, the fixed frame of the swing door comprises side plates and a top plate 2, the side plates are parallel to each other and the upper edges of the side plates are connected to the top plate 2. The upper surface of the swing door moving plate 1 is flush with the top plate 2 when the swing door moving plate 1 is in the closed position. By making the swing door moving plate 1 in the closed position flush with the top plate 2, the vehicle can pass the swing door moving plate 1 smoothly and the vehicle bumping is reduced.

[0039] As a possible example, in the embodiment, the swing door mechanism comprises a translation mechanism, a translation block 7, connecting rods 9, a guide slot 6 and rolling bodies 12. The translation mechanism is located below the top plate 2 and is used to translate the translation block 7 along the length direction of the side plates. The connecting rods 9 are parallel to each other and the first ends of the connecting rods 9 are hinged to the translation block 7 through first hinge shafts 8, and the second ends of the connecting rods 9 are hinged to the swing door moving plate 1 through second hinge shafts 10, so that the connecting rods 9, the swing door moving plate 1 and the translation block 7 form a parallelogram connecting rod 9 mechanism. The guide slot 6 is connected to the side plates and is used to guide the rolling bodies 12.

[0040] When the translation mechanism makes the translation block 7 close to the closed position, the rolling bodies 12 move upward along the guide slot 6, so that the distance between the swing door moving plate 1 and the translation block 7 increases, until the connecting rods 9 are perpendicular to the translation block 7 (the perpendicular angle has stronger bearing capacity).

[0041] When the rolling bodies 12 do not enter the guide slot 6, the lower surface of the swing door moving plate 1 contacts the translation block 7 and the swing door moving plate 1 is supported by the translation block 7. As the translation block 7 approaches the closed position, the rolling bodies 12 enter the guide slot 6 and move upward in the guide slot 6, driving the entire swing door moving plate 1 to gradually move away from the translation block 7. When the swing door moving plate 1 is flush with the top plate 2, the translation process of the translation block 7 stops.

[0042] Similarly, when the translation block 7 moves away from the closed position, the entire swing door moving plate 1 gradually approaches the translation block 7 until it is placed on the translation block 7.

[0043] As a possible example, in the embodiment, the translation mechanism comprises a driving sprocket, a driven sprocket, a first chain 5 and a driving assembly. The driving sprocket and the driven sprocket are both rotatably installed on the side plates, and the driving sprocket and the driven sprocket are transmission connected through the first chain 5. The driving assembly is used to drive the driving sprocket to rotate. The translation block 7 is connected to the upper horizontal part of the first chain 5 or to the lower horizontal part of the first chain 5.

[0044] When the driving assembly drives the driving sprocket to rotate, the translation block 7 is always located between the driving sprocket and the driven sprocket, that is, the translation block 7 only translates and does not rotate.

[0045] However, the actual implementation is not limited thereto. For example, the translation mechanism can also be other structures such as a hydraulic cylinder, as long as the reciprocating linear motion of the translation block 7 along the length direction of the side plate can be achieved.

[0046] As a possible example, in the embodiment, the first chain 5 is connected to the translation block 7 through the connecting rods 11, the number of the connecting rods 11 is multiple, the lower ends of the multiple connecting rods 11 are respectively fixed on different chain links of the first chain 5, and the upper ends of the connecting rods 11 are fixedly connected to the translation block 7.

[0047] In addition, the person skilled in the art can also select other ways to connect the translation block 7 and the first chain 5. For example, the translation block 7 and the first chain 5 are connected by welding or binding.

[0048] As a possible example, in the embodiment, the driving assembly includes a motor 14, a speed reducer, a shaft coupling 13, a first sprocket, a second sprocket and a second chain. The output shaft of the motor 14 is connected to the input end of the speed reducer, the output end of the speed reducer is connected to one end of the shaft coupling 13, the other end of the shaft coupling 13 is connected to the first sprocket, the first sprocket and the second sprocket are connected through the second chain, and the second sprocket is integrally connected to the driving sprocket. By setting the speed reducer, the position control precision of the opening and closing door moving plate 1 is improved.

[0049] For example, the motor 14 is preferably a servo motor to further improve the control precision.

[0050] As a possible example, in the embodiment, the number of the top plates 2 and the opening and closing door moving plates 1 is two, the closed door position is between the two top plates 2, and the two top plates 2 are respectively for the left wheel and the right wheel of the vehicle to pass through. The two opening and closing door moving plates 1 jointly close the closed door position, and the two opening and closing door moving plates 1 each correspond to an opening and closing door mechanism.

[0051] When the closed door position is opened, the left opening and closing door moving plate 1 is at least partially accommodated below the left top plate 2, and the right opening and closing door moving plate 1 is at least partially accommodated below the right top plate 2.

[0052] As a possible example, in the embodiment, the length direction of the side plate is parallel to the width direction of the vehicle, the top plate 2 is fixed with a stroke anti-collision roller 3, and the axis of the stroke anti-collision roller 3 is parallel to the length direction of the vehicle.

[0053] The two stroke anti-collision rollers 3 are respectively used to limit the limit positions of the vehicle driving to the left and to the right, so as to avoid the vehicle from rushing out of the opening and closing door mechanism 100 of the battery swap station from the left side or the right side.

[0054] Reference Figure 1The embodiment also provides a battery swap station, comprising the battery swap station opening and closing door mechanism 100, and further comprising a front wheel centering positioning device 200, a downhill ramp 300, a rear wheel centering positioning device 400, an uphill ramp 500 and a battery swap device 600.

[0055] The front wheel centering positioning device 200 is used for centering positioning of the front wheels of the vehicle, and the rear wheel centering positioning device 400 is used for centering positioning of the rear wheels of the vehicle.

[0056] The principle and implementation mode of the utility model are described by applying specific examples in the utility model, and the above embodiment is only used for helping to understand the method and core idea of the utility model; meanwhile, according to the idea of the utility model, the specific implementation mode and application range will be changed by the general technical personnel in the field. In conclusion, the content of the specification should not be understood as the limitation of the utility model.
