[0002] As more and more new energy vehicle companies enter the battery swap business, the design of battery swap stations has become more and more perfect. However, it is currently still limited by the inability to unify battery structures, making the types of battery swap stations more diversified.

[0003] Battery swapping can be roughly divided into two categories, one is chassis battery swapping, and the other is front-end battery swapping. For the battery rack compartment door, the structure is mostly a style of lifting up and down and dragging horizontally. The original intention of this structure is to occupy less space. At present, a certain front-end battery swap station adopts a lifting and folding type, which further reduces the size of a single door panel and has a higher space utilization rate. However, for front-end battery swapping, folding doors have certain defects. If extreme weather is encountered during the battery swapping process, there is no suitable component to protect the connection area between the vehicle and the station during the battery swapping process, and the existing compartment door adopts the structure of motor + guide rail + synchronous belt, which is relatively expensive. Utility Model Content

[0004] In response to the shortcomings existing in the relevant technologies, the utility model provides a two-way door structure for the battery compartment of an electric vehicle, which solves the problem of protecting the connection area between the battery swap station and the vehicle when extreme weather is encountered during the front-end battery swap process, as well as the technical problems of high cost and difficulty in installation and debugging.

[0006] The lower door is connected to the main frame through hinge II; the fan-shaped rain cloth is arranged in the gaps on both sides of the upper door and the main frame, one end of which is connected to the upper door and the other end is connected to the main frame; the brush is connected to the side of the upper door away from the mounting pin shaft.

[0007] In a possible implementation, when the electric push rod I is extended, it pushes the upper door to open outward.

[0008] In a possible implementation, the electric push rod II and the hinge II are installed on the inner side of the overall frame, and when the electric push rod II is retracted, the lower compartment door opens inward.

[0009] In a possible implementation, when the upper compartment door and the lower compartment door are closed, the entrance and exit of the battery compartment are sealed.

[0010] In a possible implementation, one end of the electric push rod I is hinged to the overall frame via a pin.

[0023] In order to solve the problem of protecting the connection area between the battery swap station and the vehicle when extreme weather occurs during the front-end battery swap process, as well as the problems of high cost and difficulty in installation and debugging, the present application provides a two-way door structure for the battery compartment of an electric vehicle.

[0024] In a possible embodiment, a two-way door mechanism of a battery compartment of an electric vehicle battery replacement system is provided, comprising: a general frame 1, installed at the entrance and exit of the battery compartment; an electric push rod Ⅰ2, one end of which is hinged on the general frame 1, and the other end is connected to the upper compartment door 5 through the upper compartment door push rod 304 on the upper compartment door 5; a hinge Ⅰ3 is installed on the outer side of the upper compartment door, one end of which is installed on the general frame 1, and the other end of which is installed on the upper compartment door 5, and the upper compartment door 5 can rotate along the pin shaft of the hinge Ⅰ3; the upper compartment door 5 is installed on the general frame 1 through the hinge Ⅰ3, and the upper compartment door 5 can rotate along the pin shaft of the hinge Ⅰ3; an electric push rod Ⅱ202, one end of which is connected to the general frame 1 through the pin shaft, and the other end is connected to the lower compartment door 7; the lower compartment door 7 is connected to the general frame 1 through the hinge Ⅱ303; a fan-shaped rain cloth 4 is arranged in the gaps on both sides of the upper compartment door 5 and the general frame 1, one end of which is connected to the upper compartment door 5, and the other end of which is connected to the general frame 1; a brush 6 is connected to the side of the upper compartment door 5 away from the installation pin shaft.

[0025] See also Figure 1 and Figure 2 ,In the above scheme, the general frame 1: is located at the entrance and exit of the battery compartment, providing the main support and fixed base of the mechanism;

[0026] Electric push rod Ⅰ2: one end is hinged on the main frame 1, and the other end pushes the upper door 5 through the upper door push rod 304 to control the opening and closing of the upper door 5;

[0027] Hinge Ⅰ3: installed at the connection between the upper door 5 and the main frame 1, installed on the outer side of the upper door 5, as a connecting piece, so that the upper door 5 can rotate or swing along the pin of the hinge Ⅰ3;

[0028] Upper door 5: mounted on the main frame 1 through hinge Ⅰ3, and can be rotated along its pin axis to open or close the battery compartment;

[0029] Electric push rod II 202: one end is installed on the main frame 1 through a pin shaft, and the other end is connected to the lower door 7 to control the opening and closing of the lower door;

[0030] Lower compartment door 7: connected to the main frame 1 through hinge II 303, used to open or close another part of the battery compartment;

[0031] Fan-shaped rain cloth 4: set in the gap between the upper door 5 and the main frame 1 to protect the interior from rain erosion;

[0032] Brush 6: Installed on the non-pin shaft side of the upper door 5, the brush 6 is a flexible structure. When opened, it will not scratch the car due to the close distance of the car, ensuring that the battery replacement process is blocked when the upper door is opened. The contact between the brush and the car can completely block the car without damaging it, and cooperate with the lower door to prevent foreign objects and rainwater from entering the gap.

[0033] This embodiment can achieve effective control of the upper door 5 and the lower door 7 through the operation of the electric push rod I2 and the electric push rod II202, ensuring the efficiency of the battery replacement process and the protection of the environment.

[0034] In a possible implementation, when the electric push rod Ⅰ2 is extended, it pushes the upper warehouse door 5 to open outward.

[0035] In the above scheme, when the electric push rod Ⅰ2 is extended, it pushes the upper door 5 to open outwards, thereby realizing the opening of the upper door.

[0036] Hinge Ⅰ3: One end is fixedly connected to the main frame 1, and the other end is connected to the upper door 5. The design of hinge Ⅰ3 allows the upper door 5 to rotate along the pin shaft at its center, and effectively converts the thrust of the electric push rod Ⅰ2 into the opening action of the upper door.

[0037] Upper door 5: connected to the main frame 1 through hinge Ⅰ3, so that it rotates around the pin shaft. When the electric push rod Ⅰ2 is extended, the driving force is transmitted to the upper door 5 through the upper door push rod 304. Due to the connecting action of hinge Ⅰ3, the driving force is converted into rotational torque, causing the upper door 5 to swing outward.

[0038] In a possible implementation, when the electric push rod II 202 contracts, the lower compartment door 7 opens inward.

[0039] In the above scheme, the electric push rod II 202 is connected to the main frame 1 through a pin shaft and can perform a contraction action under signal drive.

[0040] Hinge II 303: connects the main frame 1 and the lower door 7. When the electric push rod II 202 contracts, the lower door 7 rotates inward along the connection between the hinge II 303 and the main frame 1.

[0041] In a possible implementation, when the upper compartment door 5 and the lower compartment door 7 are closed, the entrance and exit of the battery compartment are sealed.

[0042] In the above scheme, the upper door 5 and the lower door 7, when in the closed state, cooperate with the main frame 1 to ensure that there is no gap. For example, sealing can be achieved by installing rubber or soft plastic strips on the edges of the doors, which not only improves the sealing performance but also reduces wear.

[0043] In a possible implementation, in the battery swapping system used in the present invention, when the battery swapping cart replaces the battery at the upper compartment door 5, the battery is visually positioned through the camera lens 10 on the battery swapping cart.

[0044] In the above scheme, the camera lens 10 is used to monitor and record the battery replacement process in real time to ensure the correctness and safety of the operation. The camera lens can be high-definition and can effectively shoot under low-light conditions.

[0045] In a possible implementation, one end of the electric push rod Ⅰ2 is hinged to the main frame 1 through a pin.

[0046] In the above scheme, the electric push rod I2 is hingedly mounted on the main frame 1 through a pin shaft, so that it can rotate in a small range, push the upper warehouse door push rod 304, and then push the upper warehouse door to rotate.

[0047] In a possible implementation, the hinge II 303 is installed on the inner side of the lower compartment door 7 .

[0048] In the above solution, the electric push rod II 303 pushes the lower door 7 to rotate inward along the hinge II 303, thereby realizing the inward opening of the lower door 7.

[0049] See also Figure 3 When the electric car 8 goes to the battery compartment to replace the battery, the upper compartment door 5 opens outward, the lower compartment door 7 opens inward, and the battery 301 extends out of the battery compartment entrance and exit to the front end of the electric car 8 to complete the battery replacement.

[0051] The lower door is connected to the main frame through a hinge. One end of the electric push rod is connected to the lower door and the other end is connected to the main frame support. When the electric push rod is extended, the lower door is closed, and when it is compressed, the lower door is opened inward.

[0052] The utility model of the battery compartment bidirectional door mechanism of the electric vehicle battery replacement system realizes the outward opening of the upper compartment door through the coordinated work of the electric push rod I and the hinge I, while the action of the electric push rod II controls the inward opening of the lower compartment door, thereby effectively realizing the bidirectional opening function.
