After the vehicle is fully charged, if the driver starts the vehicle without pulling out the charging gun, the pulling piece will be forced to move along with the dragging of the charging gun by the vehicle, and the elastic piece can respond to the pulling of the charging gun to move from the initial state to the final state.

For ease of illustration, only the content related to the embodiments of the present application is shown.

[0063] Please refer to Figures 1 to 3 The embodiments of the present application provide a charging device 100, which comprises a charging pile 110, a charging gun 120, a pulling device 130 and a prompting device 140. In the embodiments of the present application, the height direction of the charging pile 110 is a first direction F1, the width direction of the charging pile 110 is a second direction F2, and the length direction of the charging pile 110 is a third direction F3. The width direction and the length direction are not necessarily smaller than the length, and can also be equal. The first direction F1, the second direction F2 and the third direction F3 are used for illustrative purposes.

[0064] The charging gun 120 is electrically connected to the charging pile 110. "Electrically connected" means that the charging gun 120 and the charging pile 110 can establish a connection relationship through a conductive line. The circuit inside the charging pile 110 transmits electric energy to the charging gun 120 through the connected wire, and the charging gun 120 transmits the electric energy to the device to be charged. The electrically connected charging pile 110 can control the charging gun 120. The charging pile 110 can send control signals to the charging gun 120 through the electrical connection, for example, control the charging power, charging start and stop and other operations of the charging gun 120. At the same time, the charging gun 120 can also feed back the state information of itself (for example, whether the charging gun 120 and the charging pile 110 are connected normally, whether the charging gun 120 is overheated, etc.) to the charging pile 110 through the electrical connection.

[0065] The pulling device 130 comprises a box 131 arranged on the charging pile 110, and a pulling piece 132, an elastic piece 133 and a limiting piece 134 arranged in the box 131.

[0066] The pulling device 130 is a device for pulling the charging gun 120 out of the vehicle after starting. Specifically, the elastic member 133 is elastically fitted between the pulling member 132 and the box 131. The elastic member 133 can be a coil spring, but can also be a disc spring or other elastic component, and can be set according to actual conditions.

[0067] The "elastic fitting" means that the elastic member 133 can provide an elastic force acting between the pulling member 132 and the box 131. There can be the following cases: case one, one end of the elastic member 133 can be connected to the pulling member 132, and the other end can be connected to the limiting member 134 in the box 131, in the initial state, the elastic member 133 can be in a natural length state, when the pulling member 132 is moved by an external force, the elastic member 133 can be further compressed, and the elastic member 133 generates an elastic force opposite to the direction of the external force; case two, one end of the elastic member 133 can be connected to the pulling member 132, and the other end can be connected to the top of the inner wall of the box 131, in the initial state, the elastic member 133 can be in a natural length state, when the pulling member 132 is moved by an external force, the elastic member 133 can be stretched, and the elastic member 133 generates an elastic force opposite to the direction of the external force; case three, one end of the elastic member 133 can be connected to the pulling member 132, and the other end can be connected to the bottom of the inner wall of the box 131, the elastic member 133 can be in a natural length state, the pulling member 132 is separated from the limiting member 134, when the pulling member 132 is moved by the external force of the vehicle dragging the charging gun 120, the pulling member 132 compresses the elastic member 133, and the elastic member 133 generates an elastic force opposite to the direction of the external force.

[0068] Of course, other ways can also be used, which can be set according to actual conditions, and are not specifically limited here.

[0069] The "moving path of the pulling member 132" refers to the route through which the pulling member 132 moves relative to the box 131. For example, the moving path of the pulling member 132 can be a straight line, or can be a curved line, and can be set according to actual conditions. Figure 3For example, the pulling piece 132 can be moved relative to the box 131 along the first direction F1. When the pulling piece 132 is moved by an external force, the direction of gravity of the pulling piece 132 is on the same straight line as the moving direction, and the applied external force is mainly used to overcome the gravity of the pulling piece 132, which can make the applied external force more easily act on the pulling piece 132, so that the pulling piece 132 is more easily moved relative to the box 131. Of course, the pulling piece 132 can also be moved in other directions, which can be set according to actual conditions and is not specifically limited here. The limiting piece 134 is a component for limiting the movement range of the pulling piece 132. After the pulling piece 132 moves along the movement path for a distance, the pulling piece 132 abuts against the limiting piece 134, which can limit the movement of the pulling piece 132. In addition, the limiting piece 134 can be integrally connected with the box 131 or fixedly connected with the box 131, which can be set according to actual conditions and is not specifically limited here.

[0070] When the charging gun 120 is subjected to an external force (for example, a drag force generated on the charging gun 120 when the vehicle is started without pulling down the charging gun 120), the pulling piece 132 can be moved relative to the box 131 by the external force. Through the movement of the pulling piece 132, the elastic piece 133 is elastically deformed, thereby playing a role of buffering the external force. At the same time, the pulling piece 132 gradually approaches the limiting piece 134 located on the movement path of the pulling piece 132 during the movement. When the elastic piece 133 is in the final state, the limiting piece 134 limits the movement of the pulling piece 132. At this time, the pulling piece 132 can exert a pulling force on the charging gun 120, thereby pulling down the charging gun 120 from the started vehicle, reducing the occurrence of safety accidents such as the charging pile 110 being dragged down, and playing a certain protection role. The pulling device 130 can flexibly cope with possible unexpected situations after charging is completed, and ensure the safe and stable operation of the charging equipment 100.

[0071] The prompting device 140 is a device for prompting the driver that the charging gun 120 is not pulled down, and includes a detection piece 141 and a prompting piece 142 electrically connected. Specifically, the detection piece 141 is located on the movement path of the pulling piece 132, and the detection piece 141 can generate a detection signal in response to the movement of the pulling piece 132. The prompting piece 142 is used to prompt in the case that the detection signal is a preset detection signal.

[0072] For example, the detection member 141 can be a pressure sensor, the pulling member 132 can be moved towards the direction where the pressure sensor is located under the external force, and the pulling member 132 can generate a gradually increasing pressure on the pressure sensor as the pulling member 132 gradually approaches the pressure sensor. When the movement of the pulling member 132 causes the pressure sensor to bear a pressure corresponding to the preset detection signal, the pressure sensor detects that the detection signal is exactly the preset pressure value. At this time, the pressure sensor transmits a signal to the prompting member 142, and the prompting member 142 receives the signal and prompts the driver that the charging gun 120 has not been pulled out.

[0073] For another example, the detection member 141 can also be a displacement sensor, which is located on the movement path of the pulling member 132 and can measure the displacement of the pulling member 132. In the initial state, the displacement sensor can have an initial reading, which corresponds to the initial position of the pulling member 132, and the displacement value of the initial position can be set to zero (of course, it can also be set to other values according to actual conditions). When the pulling member 132 moves under the external force, the displacement sensor detects the displacement change of the pulling member 132. The displacement sensor can be pre-set with a specific displacement value as a preset detection signal. When the pulling member 132 moves a certain displacement and the corresponding displacement value reaches the preset detection signal, the displacement sensor transmits the preset detection signal to the prompting member 142, and the prompting member 142 prompts the driver that the charging gun 120 has not been pulled out after receiving the signal.

[0074] For another example, the detection member 141 can also be a distance sensor, which is located on the movement path of the pulling member 132. In the initial state, the distance sensor can detect the initial distance value between the pulling member 132, which is used for subsequent judgment of whether the pulling member 132 moves and the distance of the movement. At this time, the distance value corresponding to the detection signal generated by the distance sensor is the initial distance, and this detection signal can be transmitted to the prompting member 141, but the prompting member 141 will not prompt because the corresponding distance does not reach the preset detection signal. When the pulling member 132 moves under the external force, the distance between the pulling member 132 detected by the distance sensor will change. The distance sensor can be pre-set with a distance corresponding to the pulling member 132 as a preset detection signal. When the pulling member 132 moves to the preset distance, the distance detected by the distance sensor reaches the preset distance. At this time, the detection signal generated by the distance sensor is exactly the preset detection signal, and the distance sensor transmits the signal to the prompting member 142, and the prompting member 142 prompts the driver that the charging gun 120 has not been pulled out after receiving the signal.

[0075] It can be understood that the detection member 141 can be set according to actual conditions, which is not specifically limited herein.

[0076] The prompt member 142 can be a component that generates an alarm sound (e.g., a buzzer), a component that gives a voice prompt of information such as "charging gun abnormal, please check", or other forms of prompt member 142, which can be set according to actual conditions and is not specifically limited here.

[0077] The elastic member 133 can switch between the initial state and the final state in response to pulling of the charging gun 120. When the charging gun 120 is in a normal state without being pulled by external force, the elastic member 133 is in the initial state, the pulling member 132 and the limiting member 134 are separated from each other, and the entire pulling device 130 is in a relatively stable state, which can make the normal use and charging process of the charging gun 120 more stable. When the charging gun 120 is pulled by external force (for example, the driver starts the vehicle without pulling out the charging gun 120 after the vehicle is fully charged, thereby generating a drag force on the charging gun 120), the external force will be transmitted to the pulling member 132 through the charging gun 120, and the pulling member 132 will move as the external force gradually increases.

[0078] In combination with the use scenario shown by the aforementioned elastic member 133, the elastic member 133 can be in a compressed state in the initial state and in a further compressed state in the final state. Of course, the elastic member 133 can also be in a stretched state in the initial state and in a further stretched state in the final state. Specifically, when the elastic member 133 is in the initial state, the pulling member 132 is connected to one end of the elastic member 133 and the limiting member 134 in the box body 131 is connected to the other end of the elastic member 133, in combination with the foregoing description Figure 3 , the pulling member 132 can compress the elastic member 133, and the elastic member 133 is in a compressed state in the initial state. When one end of the elastic member 133 is connected to the pulling member 132 and the other end is connected to the top of the inner wall of the box body 131, the pulling member 132 can stretch the elastic member 133, and the elastic member 133 is in a stretched state in the initial state. When the elastic member 133 is in the final state, the pulling member 132 abuts against the limiting member 134, and the elastic member 133 is in a further compressed state or in a further stretched state in the final state. At this time, the limiting member 134 will limit the further movement of the pulling member 132, and then the pulling member 132 will exert a pulling force on the charging gun 120, thereby pulling the charging gun 120 off the vehicle. The configuration of the elastic member 133 and the corresponding position can be set according to the configuration of the elastic member 133 and the corresponding position, which is not specifically limited here.

[0079] In this way, in the case that the driver starts the vehicle without pulling out the charging gun 120, the pulling element 132 in the pulling device 130 is forced to move along with the vehicle dragging the charging gun 120, and the pulling element 120 generates movement in the process that the elastic element 133 responds to the pulling of the charging gun 120 from the initial state to the final state, so that the elastic element 133 is deformed. When the elastic element 133 is in the final state, the pulling element 132 abuts against the limiting element 134, the limiting element 134 limits the movement of the pulling element 132, at this time, the pulling element 132 exerts a pulling force on the charging gun 120 to pull out the charging gun 120 from the vehicle. At the same time, the detection element 141 in the prompting device 140 can generate a detection signal in response to the movement of the pulling element 132, and the prompting element 142 electrically connected to the detection element 141 will prompt in the case that the detection signal is a preset detection signal, reminding the driver that the charging gun 120 is not pulled out, which can reduce the occurrence of safety accidents of the charging pile 110 being dragged down, thereby improving the safety after charging.

[0080] In some embodiments, please continue to refer to Figure 2 and Figure 3 The pulling element 132 comprises a pulling body 132a, a first matching element 132b and a second matching element 132c.

[0081] Specifically, the pulling body 132a has a first end e1 and a second end e2 arranged oppositely, the first end e1 is matched with the elastic element 133, and the second end e2 constitutes an extension end s. The pulling body 132a can be arranged in a substantially rod shape, or can be arranged according to actual conditions, which is not specifically limited here. The first matching element 132b is arranged at the first end e1, and the second matching element 132c is arranged on the pulling body 132a and located between the first end e1 and the second end e2. Wherein, the elastic element 133 is in the initial state, the first matching element 132b is separated from the limiting element 134; the elastic element 133 is in the final state, the first matching element 132b abuts against the limiting element 134. The detection element 141 is arranged in the box body 131, and the detection element 141 is used to generate a detection signal in response to the movement of the second matching element 132c.

[0082] When the pulling element 132 moves, the first matching element 132b can be matched with the elastic element 133, so that the elastic element 133 is deformed. The second end e2 of the pulling body 132a constitutes an extension end s which can be connected with the charging gun 120, so that the pulling body 132a can also move when the charging gun 120 is dragged.

[0083] The first matching part 132b can separate the part in contact with and interacting with the limiting part 134 from the pulling body 132a. When the elastic part 133 is in the final state, the first matching part 132b is in abutment with the limiting part 134, which can better limit the movement of the pulling part 132, thereby better achieving the function of limiting. The second matching part 132c can be used to trigger the detection part 141 to generate a detection signal. By arranging the second matching part 132c, the detection part 141 can more effectively detect the movement of the pulling body 132. The second matching part 132c can make the generation of the detection signal more accurate and reliable. When the pulling part 132 moves under force, the second matching part 132c moves accordingly. The position change of the pulling part 132 is sensed by the detection part 141 and converted into a detection signal. When the second matching part 132c moves to make the detection signal of the detection part 141 a preset detection signal, the prompt part 142 electrically connected to the detection part 141 will prompt, prompting the driver that the charging gun 120 has not been pulled out.

[0084] The connection mode of the first matching part 132b and the pulling body 132a can be integral connection, welding, threaded connection, interference fit, etc. It can be set according to the actual situation, which is not limited here. Similarly, the connection mode of the second matching part 132c and the pulling body 132a can also be integral connection, welding, threaded connection, interference fit, etc. It can be set according to the actual situation, which is not limited here. For example, the first matching part 132b and the second matching part 132c are roughly block-shaped. Figure 3 In this way, the pulling body 132a can move with the first matching part 132b and the second matching part 132c during movement, so that the first matching part 132b can more accurately cooperate with the limiting part 134, and the position of the second matching part 132c can be more effectively detected by the detection part 141. In addition, the second matching part 132c is located between the first end e1 and the second end e2. In the initial state, the second matching part 132c can be in contact with the limiting part 134, or the second matching part 132c can be separated from the limiting part 134. It can be set according to the actual situation, which is not limited here.

[0085] When the pulling member 132 is not moved, the elastic member 133 is in the initial state, and the first matching member 132b is separated from the limiting member 134. In the case that the driver starts the vehicle without pulling out the charging gun 120, the pulling body 132a is forced to move along with the vehicle dragging the charging gun 120, the first matching member 132b moves to make the elastic member 133 deformed, and the first matching member 132b gradually approaches the limiting member 134. The elastic member 133 is in the final state, and the first matching member 132b abuts against the limiting member 134, which can limit the movement of the pulling body 132a. Then, the pulling body 132a exerts a pulling force on the charging gun 120, so as to pull out the charging gun 120 from the vehicle.

[0086] The detection member 141 is arranged in the box body 131, and is configured to generate a detection signal in response to the movement of the second matching member 132c. Specifically, the second matching member 132c moves during the movement of the pulling body 132a, and the detection member 141 generates the detection signal by detecting the movement of the second matching member 132c. When the elastic member 133 is in the final state and the first matching member 132b abuts against the limiting member 134, the second matching member 132c makes the detection member 141 generate a preset detection signal, and at this time, the preset detection signal is converted into an electrical signal and transmitted to the prompt member 142 electrically connected to the detection member 141, so that the prompt member 142 can give a corresponding prompt to remind the driver that the charging gun is not pulled out.

[0087] In this way, when the elastic member 133 is in the initial state, the first matching member 132b is separated from the limiting member 134, so that the normal plug-pull operation of the charging gun 120 is not hindered, and the charging process is more smoothly performed. In the case that the driver starts the vehicle without pulling out the charging gun 120, when the elastic member 133 reaches the final state due to the movement of the pulling body 132a, the first matching member 132b abuts against the limiting member 134, which can limit the further movement of the pulling member 132a, and the pulling body 132a exerts a pulling force on the charging gun 120 to pull out the charging gun 120 from the vehicle, thereby effectively reducing the occurrence of safety accidents such as the charging pile being pulled down. Meanwhile, the detection member 141 can generate a detection signal in response to the movement of the second matching member 132c, and when the preset detection signal is detected, the detection signal can be transmitted to the prompt member 142 electrically connected to the detection member 141, so as to remind the driver that the charging gun is not pulled out, thereby reducing the occurrence of safety accidents and improving the safety after the charging is completed.

[0088] In some embodiments, please continue to refer to Figure 3 The elastic member 133 is located between the first matching member 132b and the limiting member 134.

[0089] Specifically, when the charging gun 120 is not subjected to external force dragging, the pulling member 132 does not produce movement, the elastic member 133 is in an initial state, and the elastic member 133 does not affect the normal static state of the pulling body 132a. When the charging gun is subjected to external force dragging, the external force is first transmitted to the pulling body 132a and then acts on the first matching member 132b. Since the elastic member 133 is located between the first matching member 132b and the limiting member 134, the first matching member 132b will exert pressure on the elastic member 133 under the action of the external force, so that the elastic member 133 is elastically deformed. In the process of being elastically deformed, the elastic member 133 will store energy and generate a corresponding reaction force. This reaction force will be transmitted to the pulling body 132a through the first matching member 132b, thereby playing a role of buffering the external force. With the continuous increase of the external force, the deformation of the elastic member will also gradually increase, and the elastic member 133 gradually changes from the initial state to the final state, so that the first matching member 132b abuts against the limiting member 134. At this time, the limiting member 134 will limit the movement of the first matching member 132b, thereby limiting the further displacement of the pulling body 132a, and reducing the risk of over-dragging of the charging gun 120.

[0090] In this way, by locating the elastic member 133 between the first matching member 132b and the limiting member 134, when the charging gun 120 is subjected to accidental dragging, the pulling body 132a is subjected to external force and moves, the first matching member 132b moves to compress the elastic member 133 and thereby absorb and store energy, thereby reducing the direct impact of the external force and effectively reducing the impact of the instantaneous impact force on the pulling device 130 and the charging pile 110. At the same time, when the charging gun 120 is subjected to dragging, the first matching member 132b can abut against the limiting member 134 when the elastic member 133 deforms to a certain extent, i.e., when the elastic member is in the final state.

[0091] Of course, in other embodiments, the elastic member 133 can also be located between the first matching member 132b and the box body 131, and can also be located between the second matching member 132c and the box body 131. The specific mode can be set according to the actual situation, and is not specifically limited here.

[0092] In some embodiments, please continue to refer to Figure 3 The elastic member 133 is sleeved outside the pulling body 132a and located between the first matching member 132b and the limiting member 133.

[0093] Specifically, sleeving the elastic member 133 outside the pulling body 132a can make more full use of the space around the pulling body 132a to install the elastic member 133, reducing the occupation of too much additional space. Compared with placing the elastic member 133 at other independent positions, sleeving the elastic member 133 outside the pulling body 132a can make the structure of the entire pulling device 130 more compact.

[0094] In this way, the elastic member 133 is sleeved outside the pulling body 132a and located between the first matching member 132b and the limiting member 133, so that the elastic member 133 and the pulling body 132a are more closely and stably structured, and the pulling body 132a is more stably located in the box body 131 when not subjected to external force, and the movement process of the pulling body 132a is more stable.

[0095] Of course, the elastic member 133 can also not be sleeved on the pulling body 132a, but be located between the first matching member 132b and the limiting member 133 alone, which can be set according to actual conditions.

[0096] In some embodiments, please continue to refer to Figure 3 One end of the elastic member 133 is connected to the first matching member 132b, and the other end is connected to the limiting member 134.

[0097] Specifically, the elastic member 133 is connected between the first matching member 132b and the limiting member 134, which can make the pulling member 132 more stably located in the box body 131 when the elastic member 133 is in an initial state. When the pulling member 132 moves under external force, the distance between the first matching member 132b and the limiting member 134 gradually decreases, and the elastic member 133 connected between the first matching member 132b and the limiting member 134 can play a buffering role, reducing damage to the charging device 100. In addition, after the pulling member 132 pulls the charging gun 120 off the vehicle, the elastic member 133 connected between the first matching member 132b and the limiting member 134 is in a final state, and the elastic member 133 needs to return to the original state to release the elastic potential energy, which can make the pulling member 132 return to the original position.

[0098] In this way, by connecting one end of the elastic member 133 to the first matching member 132b and the other end to the limiting member 134, the elastic member 133 can make the pulling body 132a more stably located in the box body 131, and also play a role in buffering external force. The elastic member 133 connected between the first matching member 132b and the limiting member 134 can also make the pulling member 132 return to the initial position, so that the charging device can be operated next time, improving the repeatability and stability of the device.

[0099] Of course, one end of the elastic member 133 can not be connected to the first matching member 132b, and the other end can not be connected to the limiting member 134, so that the elastic member 133 can be directly sleeved on the pulling body 132a, which can be set according to actual conditions, and is not specifically limited here.

[0100] In some embodiments, please continue to refer to Figure 3, the elastic member 133 is in the initial state, the pulling device 130 is in the normal unstressed state, the first matching member 132b abuts against the inner wall of the box body 131, so that the pulling member 132 can remain relatively stable, so that the pulling member 132 will not move randomly when it is not stressed.

[0101] In this way, by abutting the first matching member 132b against the inner wall of the box body 131, the stability of the entire charging device 100 can be improved, and the pulling device 130 can form a relatively stable structure with the box body 131 in the initial state. At the same time, due to the abutment of the first matching member 132b against the inner wall of the box body 131, the possibility of movement of the pulling member 132 can be reduced when the elastic member 133 is in the initial state, thereby improving the stability of the charging process and improving the reliability of the charging device 100.

[0102] Of course, the first matching member 132b can also not abut against the inner wall of the box body 131, and can be set according to actual conditions, which is not specifically limited here.

[0103] In some embodiments, please continue to refer to Figure 3 The limiting member 134 is provided with a guide hole k, and the pulling body 132a is arranged in the guide hole k.

[0104] Specifically, the limiting member 134 can be fixedly connected with the box body 131, and the limiting member 134 can separate the box body 131 into two cavities Q (a first cavity Q1 and a second cavity Q2). The limiting member 134 can be located in the middle of the inside of the box body 131, or can be located at other positions inside the box body 131, and can be set according to actual conditions. For example, Figure 3 For example, the limiting member 134 separates the box body 131 into two cavities Q (a first cavity Q1 and a second cavity Q2), and the pulling body 132a is arranged in the guide hole k and located in the two cavities Q.

[0105] The guide hole k on the limiting member 134 provides a direction for the movement of the pulling body 132a. When the charging gun 120 is dragged by an external force, the pulling body 132a will move under the action of the force. Since the pulling body 132a is arranged in the guide hole k, the guide hole k can guide the pulling body 132a, so that the pulling body 132a moves along a specific straight line direction, reducing the risk of deviation, shaking or irregular movement. In addition, the shape and size of the guide hole k can be set according to the shape and size of the pulling body 132a, so that the pulling body 132a can be arranged in the guide hole k and also can move through the guide hole k. The size of the guide hole k can be set according to actual conditions, which is not specifically limited here.

[0106] In this way, the guide hole k is arranged on the limiting member 134, and the pulling body 132a is arranged in the guide hole k, so that the pulling body 132a is always kept in a relatively stable linear movement direction, and the stability and reliability of the pulling device 130 are improved.

[0107] In some embodiments, please continue to refer to Figure 4 The detection member 141 is configured as a pressure sensor.

[0108] Specifically, in the process that the charging gun 120 is dragged to move the pulling member 132 under the dragging force, the second matching member 132c gradually approaches the pressure sensor, and a gradually increasing pressure is generated on the pressure sensor. The pressure sensor can sense the change of the pressure, and when the preset pressure value is reached, the pressure sensor can transmit a signal to the prompting member 142, so that the prompting member 142 gives a prompt. Inside the box body 131, the space is usually limited, and the volume of the pressure sensor is small, so it is convenient to install on the movement path of the pulling member 132. Compared with other sensors, the pressure sensor can be more compactly installed in the box body 131, so that the dragging force is converted into a pressure signal for detection. In addition, since the pulling device 130 may be worn or unstable during the movement of the pulling member 132, if other sensors are used, it may lead to inaccurate detection of the pulling member 132, and the detection member 141 configured as a pressure sensor can improve the accuracy of detection.

[0109] In this way, by configuring the detection member 141 as a pressure sensor, when the pulling member 132 gradually approaches the detection member 141, the detection member 141 can more accurately detect the signal, and when the preset detection signal is reached, it can effectively transmit to the prompting member 142 to remind the driver that the charging gun 120 is not pulled out, reduce the occurrence of safety accidents such as the charging pile 110 being pulled down due to the charging gun 120 being dragged, and improve the safety after charging is completed.

[0110] Figure 3 Partially shows Figure 5 Partially shows a local enlarged structure schematic view of the charging equipment; Figure 1 Partially shows a part of the charging equipment provided by some embodiments of the present application. For convenience, only the content related to the embodiments of the present application is shown.

[0111] In some embodiments, please continue to refer to Figure 4 , and refer to Figure 5 and Figure 4 The charging equipment 100 further comprises a reset device 150 and a traction member 160.

[0112] Specifically, the reset device 150 comprises a rotating member 151 rotatably arranged at the extended end s of the pulling member 132, and an elastic element 152 arranged around the rotating member 151. The rotating member 151 is a component rotatably arranged at the extended end s of the pulling member 132. The rotating member 151 serves to provide a basis for the arrangement of the elastic element 152. The elastic element 152 is a component with elasticity, which can be a coil spring or a disc spring, or the like, and can be arranged according to actual conditions, which is not specifically limited herein. For example, as shown in the figure, the elastic element 152 is a coil spring arranged around the rotating member 151. One end of the elastic element 152 is fixedly connected to the rotating member 151, and the elastic element 152 has a terminal end t. The pulling member 160 has a connecting end c and a pulling end q arranged oppositely, the connecting end c is connected to the terminal end t, and the pulling end q is connected to the charging gun 120. The pulling member 160 can be a pulling rope or other pulling component, which can be arranged according to actual conditions, which is not specifically limited herein. In addition, the pulling end q can be detachably connected to the charging gun 120, and the connecting end c can also be detachably connected to the terminal end t, so that the pulling member 160 can be replaced more conveniently when it is damaged. Figure 6

[0113] Due to the arrangement of the elastic element 152, the charging gun 120 can continue to move a certain displacement when subjected to a dragging force. At this time, the pulling device 130 is in a relatively static state, and the elastic element 152 connected to the charging gun 120 through the pulling member 160 will be deformed with the movement of the charging gun 120. In the case of the coil spring as the elastic element 152, the coil spring will be further stretched with the rotation of the rotating member 151, thereby storing elastic potential energy. When the charging gun 120 is dragged to a certain extent, the deformation of the coil spring reaches a relatively stable state. The pulling member 132 starts to move in the first direction F1, and when the first cooperating member 132b moves to abut against the limiting member 134, the movement of the pulling member 132 is limited, and the pulling member 132 generates a pulling force on the charging gun 120, thereby pulling the charging gun 120 off the vehicle. Subsequently, the coil spring returns to the original state, releases the elastic potential energy, and the elastic restoring force of the coil spring drives the rotating member 151 to rotate reversely, the rotation of the rotating member 151 drives the pulling member 160 to retract, and the pulling member 160 can pull the charging gun 120 towards the charging device 100, so that the charging gun 120 gradually returns to the initial position.

[0114] In this way, by arranging the reset device 150, the charging gun 120 can be pulled back to the original position by the elastic element 152 through the pulling member 160 after being pulled off, thereby reducing the occurrence of the charging gun 120 falling to the ground after being pulled off, and reducing the damage to the charging device 100.

[0115] Figure 5 As shown in the figure, Figure 1 ​The partial charging device is shown in a cross-sectional structure schematic view in the cross-sectional direction of B-B. For ease of illustration, only the content related to the embodiments of the present application is shown.

[0116] In some embodiments, please continue to refer to Figure 4 , Figure 5 and Figure 6 , and refer to Figure 1 , the charging device 100 further comprises a sleeve member 170 and a fastening assembly 170.

[0117] The sleeve member 160 is a component for sleeving the charging gun 120. Specifically, the sleeve member 160 is sleeved outside the charging gun 120. The fastening assembly 170 is a component for fastening the traction member 160 to the charging gun 120. The fastening assembly 170 comprises a mounting member 181 provided on the sleeve member 160, and a fastening member 170 threadedly matched with the mounting member 180. The mounting member 180 and the fastening member 170 are components for connecting the traction member 160 to the charging gun. The mounting member 180 is provided with a threaded hole w matched with the fastening member 182, so as to achieve the pressing and fixing of the traction end q, and the mounting member 180 is provided with a channel d in communication with the threaded hole w.

[0118] Wherein, the traction end q extends into the threaded hole w through the channel d, and the fastening member 182 presses the part of the traction end q in the threaded hole w by means of the threaded hole w. Specifically, the fastening member 182 can be advanced or retreated in the threaded hole w by rotating the fastening member 182. When the traction end q extends into the threaded hole w through the channel d, the fastening member 182 presses the traction end q by means of the threaded hole w. This can make the connection between the traction member 160 and the charging gun 120 more firm and reliable. When the charging gun 120 is dragged by external force, the fastening assembly 180 can prevent the traction member 160 from easily separating from the charging gun 120.

[0119] In addition, the traction end q of the traction member 160 can be detachably tied on the fastening member 180, which can be set according to actual conditions and is not specifically limited here.

[0120] In other embodiments, the sleeve member 170 can also be provided with a component such as a bell that can emit a sound. When the driver forgets to pull out the charging gun 120 and starts the vehicle at the same time, the component such as the bell that can emit a sound can better remind the driver that the charging gun 120 has not been pulled out, reduce the risk of the charging gun 120 being excessively dragged, and improve the safety after charging.

[0121] In some embodiments, please continue to refer to Figure 4 and Figure 1 , the elastic element 133 is configured as a coil spring.

[0122] The shape of the coil spring is similar to that of a mosquito coil, which can be better wound on the rotating member 151, so that the elastic element 133 can be better matched with the rotating member 151.

[0123] In this way, by configuring the elastic element 133 as a coil spring, when the charging gun 120 is dragged for a distance, the coil spring will be stretched and store elastic potential energy. Once the external force disappears, the coil spring can gradually release the elastic potential energy, thereby being able to play a buffering role, and the coil spring can pull the charging gun 120 back to the initial position smoothly through the traction member 160. In addition, the elastic restoring force of the coil spring is relatively stable and will not be significantly weakened due to frequent use, so that the charging device 100 can maintain good reset performance during long-term use.

[0124] In some embodiments, please continue to refer to Figure 4 and Figure 7 The traction member 160 is configured as a rope member.

[0125] In the charging device 100, since the position and movement direction of the charging gun 120 will change at any time, the rope member can flexibly follow the movement of the charging gun 120 to bend and stretch. At the same time, the rope member is easy to replace, and if the rope member is worn, broken, or the like during use, it can be more conveniently replaced without a complex maintenance process, which can improve the maintainability of the charging device 100.

[0126] Figure 1 Part of the structure of the charging device of some embodiments of the application is shown; only the content related to the embodiments of the application is shown for ease of description.

[0127] In some embodiments, please continue to refer to Figure 7 and refer to ​ The charging device 100 further comprises a current sensor I, a voltage sensor V, and a processor U.

[0128] Specifically, the current sensor I is arranged in the charging pile 110, and the current sensor I is located on the current path of the charging pile 110. The voltage sensor V is arranged in the charging pile 110, and the voltage sensor V is located at the output voltage end of the charging pile 110. In the path of the current from the power grid into the charging pile 110 and flowing to the electric vehicle, the voltage sensor V can be installed at the output voltage end of the charging pile 110, and the voltage sensor can be used to monitor the size of the output voltage of the charging pile 110. The current sensor I can be used to collect current data in real time. The processor U is electrically connected to the current sensor I and the voltage sensor V.

[0129] When the electric vehicle is connected to the charging pile 110 and starts charging, the current sensor I and the voltage sensor V of the charging pile 110 will collect current and voltage data in real time and send them to the processor U. The processor U can determine whether the current load type is an electric vehicle, the charging mode of the electric vehicle, and the load size of the charging power by comparing these data with the preset threshold. In addition, the processor U can also dynamically adjust the charging power and charging strategy according to the real-time battery status and charging demand of the electric vehicle to ensure the safety and efficiency of the charging process. When the battery power is low, the charging pile 110 may use a larger charging power for fast charging, and when the battery power is close to full, the charging power may be reduced to avoid overcharging.

[0130] In this way, through the cooperative work of the current sensor I, the voltage sensor V and the processor U, the charging device 100 can more accurately monitor and control the current and voltage during the charging process, ensuring the safe, efficient and stable operation of the charging process.

[0131] The technical features of the above-mentioned embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described, but as long as the combination of the technical features does not exist contradictory, it should be considered as the scope of the present application.
