DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] The object of the present invention is to provide a battery swap station opening and closing door mechanism and a battery swap station, so as to simplify the overall structure and improve the load-bearing capacity and battery swap efficiency.

[0032] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0033] Reference Figure 1 to Figure 6 The present embodiment provides an opening and closing door mechanism 100 of a battery swap station, comprising an opening and closing door fixed frame, an opening and closing door movable plate 1 and an opening and closing door mechanism.

[0034] The opening and closing door fixing frame is used to be installed above the tunnel, and a closed door position is provided on the opening and closing door fixing frame. The opening and closing door moving plate 1 is installed on the opening and closing door fixing frame, and can reach and leave the closed door position by shifting. The opening and closing door mechanism is installed on the opening and closing door fixing frame, and is used to drive the opening and closing door moving plate 1 to shift.

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

[0036] This embodiment does not adopt the method of lifting the electric vehicle before replacing the battery, but sets a pit below the battery replacement position of the vehicle, and the battery replacement equipment 600 is located in the pit. Before the vehicle drives to the battery replacement position, the opening and closing door movable plate 1 is in the closed door position. After the vehicle drives to the battery replacement position, the front wheels of the vehicle have passed the closed door position, and the battery pack of the vehicle is located directly above the closed door position. At this time, the opening and closing door mechanism moves the opening and closing door movable plate 1 away from the closed door position, and the battery replacement equipment 600 extends upward from the pit, and the battery replacement is realized through subsequent operations.

[0037] The above battery replacement process does not require the installation of a lifting device, which simplifies the structure of the battery replacement station and reduces the construction cost of the battery replacement station. In addition, since the vehicle lifting process is omitted, the owner and passengers can complete the battery replacement without getting off the vehicle, which improves the user experience and battery replacement efficiency.

[0038] As a possible example, in this embodiment, the opening and closing door fixing frame includes a side plate and a top plate 2, the number of the side plates is multiple and parallel to each other, and the upper edges of the side plates are connected to the top plate 2. When the opening and closing door movable plate 1 is in the door closing position, its upper surface is flush with the top plate 2. By making the opening and closing door movable plate 1 in the door closing position equal in height to the top plate 2, the vehicle can smoothly pass the opening and closing door movable plate 1, thereby reducing vehicle bumps.

[0039] As a possible example, in this embodiment, the door opening and closing mechanism includes a translation mechanism, a translation block 7, a connecting rod 9, a guide groove 6 and a rolling body 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 plate. There are multiple connecting rods 9 and they are parallel to each other. The first end of the connecting rod 9 is hinged to the translation block 7 through the first hinge shaft 8, and the second end of the connecting rod 9 is hinged to the door opening and closing moving plate 1 through the second hinge shaft 10, so that the connecting rod 9, the door opening and closing moving plate 1 and the translation block 7 form a parallelogram connecting rod 9 mechanism. The guide groove 6 is connected to the side plate and is used to guide the rolling body 12.

[0040] When the translation mechanism moves the translation block 7 closer to the door closing position, the rolling body 12 moves upward along the guide groove 6, increasing the distance between the door opening and closing moving plate 1 and the translation block 7 until the connecting rod 9 is perpendicular to the translation block 7 (the vertical angle has a stronger load-bearing capacity). When the translation mechanism moves the translation block 7 away from the door closing position, the rolling body 12 moves downward along the guide groove 6, decreasing the distance between the door opening and closing moving plate 1 and the translation block 7.

[0041] When the rolling body 12 does not enter the guide groove 6, the lower surface of the door moving plate 1 contacts the translation block 7, and the door moving plate 1 is supported by the translation block 7. As the translation block 7 approaches the door closing position, the rolling body 12 enters the guide groove 6 and moves upward in the guide groove 6, driving the entire door moving plate 1 to gradually move away from the translation block 7. When the door moving plate 1 is at the same height as the top plate 2, the translation block 7 stops the translation process.

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

[0043] As a possible example, in this embodiment, the translation mechanism includes a driving sprocket, a driven sprocket, a first chain 5 and a driving assembly. The driving sprocket and the driven sprocket are both rotatably mounted on the side plate, 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 driving sprocket, that is, the translation block 7 only translates but does not rotate.

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

[0046] As a possible example, in this embodiment, the first chain 5 is connected to the translation block 7 through a connecting rod 11. There are multiple connecting rods 11. The lower ends of the multiple connecting rods 11 are respectively fixed on different 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, those skilled in the art may also select other methods to connect the translation block 7 to the first chain 5. For example, the translation block 7 and the first chain 5 may be connected by welding or tying.

[0048] As a possible example, in this embodiment, the driving assembly includes a motor 14, a reducer, a 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 reducer, the output end of the reducer is connected to one end of the coupling 13, the other end of the coupling 13 is connected to the first sprocket, the first sprocket and the second sprocket are connected through the second chain transmission, and the second sprocket is connected to the driving sprocket in one piece. By providing a reducer, the position control accuracy of the opening and closing door moving plate 1 is improved.

[0049] Exemplarily, the motor 14 is preferably a servo motor to further improve the control accuracy.

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

[0051] When the door is in the closed position, the left opening and closing door movable plate 1 is at least partially stored under the left top plate 2, and the right opening and closing door movable plate 1 is at least partially stored under the right top plate 2.

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

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

[0054] Reference Figure 1The present embodiment further provides a battery swap station, including the above-mentioned battery swap station opening and closing door mechanism 100, and also including a front wheel centering positioning device 200, a down ramp 300, a rear wheel centering positioning device 400, an up ramp 500 and a battery swap device 600. The front wheel centering positioning device 200 is located in front of the battery swap station opening and closing door mechanism 100, and the down ramp 300 is located in front of the front wheel centering positioning device 200. The rear wheel centering positioning device 400 is located behind the battery swap station opening and closing door mechanism 100, and the up ramp 500 is located behind the rear wheel centering positioning device 400. The battery swap device 600 is arranged in the tunnel.

[0055] The front wheel centering positioning device 200 is used to center the front wheels of the vehicle, and the rear wheel centering positioning device 400 is used to center the rear wheels of the vehicle. Through centering positioning, the position of the vehicle in the width direction is adjusted to facilitate subsequent battery replacement operations.

[0056] The present invention uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only used to help understand the method and core ideas of the present invention. At the same time, for those skilled in the art, according to the ideas of the present invention, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as limiting the present invention.
