Description

Technical Field

[0001] This application relates to the field of vehicle technology, and in particular to vehicle-side charging devices, charging systems, and vehicles. Background Technology

[0002] The charging system used in vehicles includes a ground-side charging device and a vehicle-side charging device installed on the vehicle. The vehicle-side charging device includes a vehicle-side charging interface, and the ground-side charging device includes a ground-side charging interface. When the vehicle needs to be charged, the vehicle-side charging interface is connected to the ground-side charging interface.

[0003] Vehicle-mounted charging devices are typically equipped with a cover assembly. When the vehicle is not charging, the cover assembly is closed to block the vehicle-mounted charging interface and prevent rainwater, mud, and other foreign objects from entering. When the vehicle needs to be charged, the cover assembly is opened to expose the vehicle-mounted charging interface, allowing the vehicle-mounted charging interface to connect to the ground charging interface.

[0004] However, the reliability of the cover component in the relevant technology is poor. When the vehicle-side charging device is not charging, the cover component may accidentally open, affecting the protection of the vehicle-side charging interface and thus its performance. Furthermore, during charging, the vehicle-side charging device and the ground-side charging device are only connected to the vehicle-side charging interface through the ground-side charging interface, resulting in poor connection reliability. All of the above situations can easily lead to charging abnormalities. Utility Model Content

[0005] Therefore, it is necessary to provide a vehicle-side charging device, a charging system, and a vehicle to address the issues of poor reliability of the cover component in related technologies, which affects the protection effect on the vehicle-side charging interface, and poor connection reliability between the ground-side charging interface and the vehicle-side charging interface during charging.

[0006] In a first aspect, this application provides a vehicle-side charging device applied to a vehicle, comprising:

[0007] The vehicle-side connector includes a vehicle-side charging interface for connecting to the ground-side charging interface of a ground-side charging device to charge the vehicle.

[0008] A cover assembly is movably disposed on the vehicle-end connector. The cover assembly has a covered position and an open position to cover or open the vehicle-end charging interface.

[0009] When the cover assembly is in the covered position, the locking assembly is used to lock the relative position of the cover assembly and the vehicle-end connector. When the cover assembly is in the open position and the vehicle-end charging interface is connected to the ground-end charging interface, the locking assembly is used to lock the relative position of the vehicle-end connector and the ground-end charging device.

[0010] In one embodiment, the vehicle-end connector further includes a first base, a locking component is disposed on the first base, and the cover component further includes a first mating portion;

[0011] When the cover assembly is in the blocked position, the locking assembly locks with the first mating part. When the ground charging interface is connected to the vehicle charging interface, the locking assembly locks with the ground charging device.

[0012] In one embodiment, the locking assembly includes a locking actuator, which includes a locking end for locking with a first mating part. When the cover assembly is in the blocked position, a first receiving cavity is formed between the first base and the cover assembly, and the locking end is located in the first receiving cavity.

[0013] In one embodiment, a first receiving groove is provided on the first base, the first receiving groove having a first opening, and when the cover assembly is in the blocking position, the cover assembly blocks the first opening to form a first receiving cavity between itself and the first base; or...

[0014] The cover assembly is provided with a second receiving groove, which has a second opening. When the cover assembly is in the blocking position, the first base blocks the second opening to form a first receiving cavity between itself and the cover assembly.

[0015] In one embodiment, when the cover assembly is in the open position and the vehicle-side charging interface is connected to the ground-side charging interface, a second receiving cavity is formed between the ground-side charging device and the first base, and the locking end is located in the second receiving cavity.

[0016] In one embodiment, a first receiving groove is provided on the first base, the first receiving groove having a first opening. When the cover assembly is in the open position and the vehicle-side charging interface is connected to the ground-side charging interface, the ground-side charging device blocks the first opening to form a second receiving cavity between itself and the first base; or...

[0017] When the locking end is locked in place with the ground charging device, the locking end protrudes outward from the first base. The ground charging device is provided with a third receiving groove with a third opening. During the connection between the vehicle charging interface and the ground charging interface, the third opening is used for the locking end to be embedded in the third receiving cavity. When the cover assembly is in the open position and the vehicle charging interface is connected to the ground charging interface, the first base blocks the third opening to form a second receiving cavity with the ground charging device.

[0018] In one embodiment, the locking end protrudes outward from the first base; or...

[0019] The locking actuator is embedded in the first base so that the locking actuator is not exposed outside the first base.

[0020] In one embodiment, the first base has an internal mounting cavity, and the locking assembly includes a locking actuator and a lock body. The lock body is located in the mounting cavity and is driven to connect with the locking actuator so that the locking actuator can lock into the first mating part or the ground charging device.

[0021] In one embodiment, the locking actuator is movably disposed relative to the first base, the locking actuator having a locked position and an unlocked position, and the lock body includes a drive part and a transmission part, the drive part being drivenly connected to the locking actuator through the transmission part.

[0022] In one embodiment, the locking component further includes:

[0023] The manual unlocking unit is connected to the transmission unit. By operating the manual unlocking unit, the locking actuator can be driven to switch from the locked position to the unlocked position.

[0024] In one embodiment, the vehicle-side charging device further includes:

[0025] The sensor, which is in communication with the locking assembly, is used to detect the connection signal between the vehicle-side charging interface and the ground-side charging device. When the sensor detects that the vehicle-side charging interface and the ground-side charging device are connected in place, it sends a locking signal to the locking assembly, which then locks the ground-side charging device and the vehicle-side connector.

[0026] Secondly, this application provides a charging system comprising:

[0027] The vehicle-side charging device of any of the above embodiments;

[0028] A ground-end charging device includes a ground-end charging interface, which is used to connect to the vehicle-end charging interface of a vehicle-end charging device to supply power to the vehicle.

[0029] The vehicle-side charging device also includes a first signal module, which is disposed on the vehicle-side connector and is used to provide a characteristic light source; the ground-side charging device also includes an image acquisition module, which is used to identify the position information of the characteristic light source in order to determine the relative position information of the ground-side charging interface and the vehicle-side charging interface.

[0030] In one embodiment, the cover assembly of the vehicle-side charging device has a first surface on which a first signal module is disposed. When the cover assembly is in the open position and the vehicle-side charging interface is connected to the ground-side charging interface, the image acquisition module is disposed opposite to the first surface.

[0031] In one embodiment, the cover assembly further includes a first mating portion disposed on a first surface, at least a portion of which protrudes from the first surface;

[0032] The first signal module includes at least two light-emitting elements, which are used to provide a characteristic light source. At least one light-emitting element is located on one side of the first mating portion along a first direction, and at least one light-emitting element is located on one side of the first mating portion along a second direction. The first direction and the second direction are perpendicular.

[0033] In one embodiment, the vehicle-side charging device is installed at the bottom of the vehicle, and the ground-side charging device is installed on the ground.

[0034] Thirdly, this application provides a vehicle that includes the vehicle-side charging device of any of the above embodiments.

[0035] The aforementioned vehicle-side charging device, installed on the vehicle, keeps the cover assembly in a shielded position when charging is not required, protecting the vehicle-side charging interface from rainwater, mud, and other foreign objects. A locking assembly secures the cover assembly to the vehicle-side connector, reducing or preventing accidental opening of the cover assembly and improving the protection of the vehicle-side charging interface. This also reduces or prevents corrosion or damage to the charging interface due to dust and water ingress, improving its performance and reducing contact problems or short circuits caused by degraded performance, thus reducing charging anomalies and improving charging reliability. When charging is required, the locking assembly is released, opening the cover assembly and exposing the vehicle-side charging interface. The vehicle-side charging interface is then connected to the ground charging interface of the ground charging device. The locking assembly again secures the relative positions of the vehicle-side connector and the ground charging device, reducing the possibility of the charging interface becoming detached during charging, reducing charging anomalies, and further improving charging reliability.

[0056] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0057] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0058] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0059] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0060] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0061] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0062] See Figure 1 and Figure 2 This application provides a vehicle-side charging device 6000, which is applied to a vehicle and includes a vehicle-side connector 6100, a cover assembly 6200, and a locking assembly 6400. The vehicle-side connector 6100 includes a vehicle-side charging interface 6110, which is used to connect with the ground charging interface 1100 of the ground charging device 1000 to charge the vehicle. The cover assembly 6200 is movably disposed on the vehicle-side connector 6100 and has a covered position and an open position to cover or open the vehicle-side charging interface 6110. When the cover assembly 6200 is in the covered position, the locking assembly 6400 is used to lock the relative position between the cover assembly 6200 and the vehicle-side connector 6100. When the cover assembly 6200 is in the open position and the vehicle-side charging interface 6110 is connected to the ground charging interface 1100, the locking assembly 6400 is used to lock the relative position between the vehicle-side connector 6100 and the ground charging device 1000.

[0063] The vehicle-mounted charging device provided in this application is installed on a vehicle. When charging is not required, the cover assembly 6200 is in a shielded position to cover the vehicle-mounted charging interface 6110, isolating it from rainwater, mud, and other foreign objects. The locking assembly 6400 locks the relative position of the cover assembly 6200 and the vehicle-mounted connector 6100, reducing or preventing accidental opening of the cover assembly 6200. This improves the protection of the vehicle-mounted charging interface 6110, reducing or preventing corrosion or damage caused by dust and water ingress. It also helps improve the performance of the vehicle-mounted charging interface 6110, reducing the risk of poor contact or short circuits due to decreased performance. To reduce charging anomalies or failures and improve the reliability of the charging process, the locking component 6400 is released from the lock between the cover component 6200 and the vehicle connector 6100 when the vehicle needs to be charged. This allows the cover component 6200 to be in the open position, exposing the vehicle charging interface 6110. The vehicle charging interface 6110 is then connected to the ground charging interface 1100 of the ground charging device 1000. The locking component 6400 locks the relative positions of the vehicle connector 6100 and the ground charging device 1000, reducing the possibility of the vehicle charging interface 6110 and the ground charging interface 1100 becoming detached during the charging process, thus reducing charging anomalies and improving the reliability of the charging process.

[0064] It should be noted that the vehicle-side charging device 6000 provided in this application can be applied to various vehicles, such as electric vehicles and hybrid vehicles, and can be installed at the front, rear, side, bottom or top of the vehicle. The specific installation position can be flexibly adjusted according to the overall layout of the vehicle and charging needs to adapt to the design requirements of different vehicle models.

[0065] This application does not limit the specific connection method between the cover assembly 6200 and the vehicle-side connector 6100. For example, it can be a rotary connection or a sliding connection, as long as it can protect the vehicle-side charging interface 6110. Compared with a rotary connection, a sliding connection is more prone to slow or stuck movement of the cover assembly 6200 due to sliding wear after long-term use, posing a risk of structural failure. At the same time, in harsh environments such as mud and snow, dirt can easily accumulate at the sliding connection location, further increasing the risk of structural failure.

[0066] The following embodiments are all illustrated using the example of the cover assembly 6200 being rotatably connected to the vehicle end connector 6100.

[0067] See Figure 5For example, the vehicle-side connector 6100 includes a first base 6130, and a vehicle-side charging interface 6110 is disposed on the first base 6130. The cover assembly 6200 includes a cover body 6210 and a flip drive member 6220. One end of the cover body 6210 is rotatably connected to the first base 6130, and the flip drive member 6220 is disposed on the first base 6130 and drivenly connected to the cover body 6210 to cause the cover body 6210 to rotate relative to the first base 6130. The cover body 6210 has a first surface 6212, and the first base 6130 has a second surface 6134. When the cover body 6210 is in the covered position, the first surface 6212 and the second surface 6134 are disposed opposite to each other. The cover 6210 is provided with a protective groove 6213, the opening of which extends through the first surface 6212. When the cover 6210 is switched from the open position to the covered position, the vehicle-side charging interface 6110 gradually fits into the protective groove 6213 from its opening. This design further enhances the protection of the vehicle-side charging interface 6110.

[0068] Furthermore, the present application does not limit the number of locking components 6400. For example, two locking components 6400 are provided, one locking component 6400 is used to lock the vehicle end connector 6100 and the cover assembly 6200, and the other locking component 6400 is used to lock the vehicle end connector 6100 and the ground charging device 1000.

[0069] In some embodiments, there is one locking component 6400, which can lock the vehicle-end connector 6100 and the cover assembly 6200, as well as the vehicle-end connector 6100 and the ground charging device 1000. This arrangement helps to simplify the structure of the device and reduce the number of parts.

[0070] The following embodiments are described using a locking component 6400 as one example.

[0071] See Figures 1 to 4 In some embodiments, the locking component 6400 is disposed on the first base 6130, and the cover component 6200 further includes a first mating portion 6230. When the cover component 6200 is in the obstructed position, the locking component 6400 locks into the first mating portion 6230. When the ground charging interface 1100 is connected to the vehicle charging interface 6110, the locking component 6400 locks into the ground charging device 1000. Disposing the locking component 6400 on the first base 6130 allows the same locking component 6400 to separately lock the cover component 6200 to the vehicle connector 6100 and to the ground charging device 1000.

[0072] For example, the ground charging device 1000 includes a second mating part 1300, a locking form of the locking component 6400 and the first mating part 6230, and the locking form of the locking component 6400 and the second mating part 1300 is the same.

[0073] See Figures 1 to 4 The locking assembly 6400 includes a locking actuator 6410, which includes a locking end 6411. The locking end 6411 is used to lock into the first mating part 6230. When the cover assembly 6200 is in the blocked position, a first receiving cavity is formed between the first base 6130 and the cover assembly 6200, and the locking end 6411 is located within the first receiving cavity. When the cover assembly 6200 is in the blocked position, the locking end 6411 is located within the first receiving cavity, which protects the locking end 6411, reducing or preventing accidental contact or damage to the locking end 6411, and helping to improve the stability of locking and unlocking.

[0074] In some embodiments, the locking actuator 6410 is embedded in the first base 6130 so that the locking actuator 6410 is not exposed outside the first base 6130. The first base 6130 is provided with a first receiving groove 6131, which has a first slot 61311. When the cover assembly 6200 is in the blocked position, the cover assembly 6200 blocks the first slot 61311 to form a first receiving cavity with the first base 6130. Exemplarily, when the cover assembly 6200 is rotatably connected to the first base 6130, the first slot 61311 penetrates the second surface 6134 of the first base 6130. When the cover assembly 6200 switches from the open position to the blocked position, the cover assembly 6200 blocks the first slot 61311. When the locking actuator 6410 is locked with the first mating part 6230, the locking end 6411 is located in the first receiving groove 6131.

[0075] See Figures 6 to 8 In other embodiments, the cover assembly 6200 is provided with a second receiving groove 6211, which has a second opening 62111. When the cover assembly 6200 is in the blocked position, the first base 6130 blocks the second opening 62111 to form a first receiving cavity between itself and the cover assembly 6200. Exemplarily, the cover body 6210 is provided with a second receiving groove 6211, the second opening 62111 penetrating the first surface 6212 of the cover body 6210, and a locking end 6411 protruding outward from the first base 6130. When the cover assembly 6200 switches from the open position to the blocked position, the locking end 6411 is inserted into the second receiving groove 6211 from the second opening 62111.

[0076] In some embodiments, when the cover assembly 6200 is in the open position and the vehicle-side charging interface 6110 is connected to the ground-side charging interface 1100, a second receiving cavity is formed between the ground-side charging device 1000 and the first base 6130, and the locking end 6411 is located within the second receiving cavity. When charging the vehicle, the locking end 6411 is located within the second receiving cavity to reduce or avoid damage or accidental contact of the exposed locking end 6411, thereby improving the stability of the locking end 6411.

[0077] This scheme does not limit the way the second receiving cavity is formed.

[0078] In some embodiments, the locking actuator 6410 is embedded within the first base 6130 so that the locking actuator 6410 is not exposed outside the first base 6130. The first base 6130 is provided with a first receiving groove 6131, which has a first slot 61311. When the cover assembly 6200 is in the open position and the vehicle-side charging interface 6110 is connected to the ground-side charging interface 1100, the ground-side charging device 1000 blocks the first slot 61311 to form a second receiving cavity (not shown) between itself and the first base 6130. For example, in use, the vehicle-side charging interface 6110 and the ground-side charging interface 1100 are plugged into each other along the first direction. When the vehicle-side charging interface 6110 and the ground-side charging interface 1100 are plugged into each other, the second surface 6134 of the first base 6130 faces the ground-side charging device 1000, and during the plugging process of the vehicle-side charging interface 6110 and the ground-side charging interface 1100, the ground-side charging device 1000 blocks the first slot 61311.

[0079] In other embodiments, when the locking end 6411 is locked to the ground charging device 1000, the locking end 6411 protrudes outward from the first base 6130. The ground charging device 1000 is provided with a third receiving groove with a third opening. The third opening is used for the locking end 6411 to be embedded in the third receiving groove. When the vehicle charging interface 6110 is connected to the ground charging interface 1100, the first base 6130 blocks the third opening to form a second receiving cavity (not shown) between itself and the ground charging device 1000.

[0080] This solution does not limit the specific form of the locking component 6400. The locking component 6400 can be set as a mechanical lock, electronic lock, electromagnetic lock, etc., as long as it can lock with the cover component 6200 and the vehicle end connector 6100 respectively, and lock the vehicle end connector 6100 with the ground end charging device 1000.

[0081] For example, when the locking component 6400 is in the form of an electromagnetic lock, the first mating portion 6230 provided on the cover component 6200 can magnetically engage with the locking component 6400. Similarly, the second mating portion 1300 of the ground charging device 1000 can magnetically engage with the locking component 6400. In other words, the locking component 6400 can achieve magnetic engagement with the first mating portion 6230 of the cover component 6200 or the vehicle connector 6100 through electromagnetic attraction, thereby achieving locking or unlocking.

[0082] In some embodiments, the locking component 6400 takes the form of an electronic lock. The following embodiments illustrate this using the example of the locking component 6400 being an electronic lock.

[0083] See Figures 1 to 4 In some embodiments, the first base 6130 has a mounting cavity 6132 inside. The locking assembly 6400 includes a locking actuator 6410 and a lock body 6420. The lock body 6420 is located inside the mounting cavity 6132 and is drivenly connected to the locking actuator 6410 so that the locking actuator 6410 can lock into the first mating part 6230 or the ground charging device 1000. Placing the lock body 6420 inside the mounting cavity 6132 avoids exposing the lock body 6420, contributing to the miniaturization of the device.

[0084] In some embodiments, the locking actuator 6410 is movably disposed relative to the first base 6130, and the locking actuator 6410 has a locked position and an unlocked position. The lock body 6420 includes a drive portion 6421 and a transmission portion 6422, and the drive portion 6421 is drivenly connected to the locking actuator 6410 through the transmission portion 6422. Exemplarily, both the drive portion 6421 and the transmission portion 6422 are located within the mounting cavity 6132.

[0085] See Figures 1 to 5In some embodiments, the locking actuator 6410 is slidably disposed relative to the first base 6130. When the locking actuator 6410 is embedded in the first base 6130: the first mating portion 6230 disposed on the cover 6210 protrudes from the first surface 6212 of the cover 6210, the first receiving groove 6131 on the first base 6130 communicates with the mounting cavity 6132, and the locking end 6411 of the locking actuator 6410 extends from the mounting cavity 6132 into the first receiving groove 6131, or is embedded from the first receiving groove 6131 into the mounting cavity 6132. When the cover assembly 6200 is in the obstructed position, the first mating portion 6230 is embedded in the first receiving groove 6131 and locks in engagement with the locking end 6411. For example, the first mating part 6230 is provided with a first locking hole 6231, and the locking end 6411 includes a locking rod that can pass through the first locking hole 6231 and lock into the first mating part 6230.

[0086] See Figures 6 to 8 In some embodiments, the locking actuator 6410 is slidably disposed relative to the first base 6130. When the locking end 6411 of the locking actuator 6410 protrudes from the first base 6130, a sliding groove is provided on the second surface 6134 of the first base 6130. The sliding groove communicates with the mounting cavity 6132. The locking end 6411 is slidably disposed in the sliding groove along the extension direction of the sliding groove. The cover body 6210 of the cover assembly 6200 is provided with a second receiving groove 6211. The second opening 62111 of the second receiving groove 6211 penetrates the first surface of the cover body 6210. The sidewall of the second receiving groove 6211 forms a first mating part 6230. A first locking hole 6231 is provided on the sidewall of the second receiving groove 6211. The locking end 6411 includes a locking rod that can pass through the first locking hole 6231 and lock into the first mating part 6230.

[0087] See Figure 3 and Figure 7 In some embodiments, the locking assembly 6400 further includes a manual unlocking part 6430, which is connected to the transmission part 6422. By operating the manual unlocking part 6430, the locking actuator 6410 can be driven to switch from the locked position to the unlocked position. When the drive part 6421 of the locking assembly 6400 fails, the manual unlocking part 6430 can be manually operated to drive the transmission part 6422 to unlock, which helps to improve the emergency use performance of the device.

[0088] For example, the drive unit 6421 drives the transmission unit 6422 to slide relative to the first base 6130. The manual unlocking unit 6430 includes a rope, one end of which is located inside the mounting cavity 6132 and connected to the transmission unit 6422, and the other end is an operating end located outside the first base 6130 for operation by an operator.

[0089] In some embodiments, the vehicle-side charging device further includes a sensor communicatively connected to a locking assembly 6400. The sensor detects the connection signal between the vehicle-side charging interface 6110 and the ground-side charging device 1000. When the sensor detects that the vehicle-side charging interface 6110 and the ground-side charging device 1000 are properly connected, it sends a locking signal to the locking assembly 6400, which then locks the ground-side charging device 1000 and the vehicle-side connector 6100. Proper connection between the vehicle-side charging interface 6110 and the ground-side charging device 1000 means that reliable charging can be achieved after connection. For example, the sensor detects whether the two are properly connected by measuring the insertion depth of the vehicle-side charging interface 6110 and the ground-side charging interface 1100 of the ground-side charging device 1000. The sensor ensures that after the vehicle-side charging interface 6110 and the ground-side charging interface 1100 are properly connected, the ground-side charging device 1000 and the vehicle-side connector 6100 are locked, thus improving the reliability of the charging process.

[0090] See Figure 1 and Figure 3 Secondly, this application provides a charging system including a vehicle-side charging device 6000 and a ground-side charging device 1000 according to any of the above embodiments. The ground-side charging device 1000 includes a ground-side connector, which includes a second base 1200 and a ground-side charging interface 1100 disposed on the second base 1200. The ground-side charging interface 1100 is used to connect to the vehicle-side charging interface 6110 of the vehicle-side charging device 6000 to supply power to the vehicle.

[0091] In some embodiments, the ground charging device 1000 further includes a second mating portion 1300, which is disposed on the second base 1200 and engages with the locking assembly 6400. Exemplarily, the second mating portion 1300 is provided with a second locking hole 1301 for engaging with the locking actuator 6410 of the locking assembly 6400.

[0092] See Figure 5In some embodiments, the vehicle-side charging device 6000 further includes a first signal module 6310, which is disposed on the vehicle-side connector 6100 and is used to provide a characteristic light source; the ground-side charging device 1000 further includes an image acquisition module 1400, which is used to identify the position information of the characteristic light source to determine the relative position information of the ground-side charging interface 1100 and the vehicle-side charging interface 6110. For example, the vehicle-side charging device 6000 is a movable structure. The vehicle-side charging device 6000 includes a walking component 1500. During the process of the vehicle-side charging device 6000 and the ground-side charging device 1000 approaching each other, the image acquisition module 1400 identifies the feature light source provided by the first signal module 6310. The image acquisition module 1400 is communicatively connected to the walking component 1500. When the feature light source identified by the image acquisition module 1400 is within a preset range, it is determined that the ground-side charging interface 1100 and the vehicle-side charging interface 6110 are properly aligned. The walking component 1500 stops walking so that the vehicle-side charging interface 6110 and the ground-side charging interface 1100 can be docked.

[0093] In some embodiments, the ground connector is movably disposed on the walking assembly 1500 along the insertion direction of the ground charging interface 1100 and the vehicle charging interface 6110, so as to facilitate the insertion of the vehicle charging interface 6110 and the ground charging interface 1100.

[0094] In some embodiments, the cover assembly 6200 of the vehicle-side charging device 6000 has a first surface 6212, on which a first signal module 6310 is disposed. When the cover assembly 6200 is in the open position and the vehicle-side charging interface 6110 is connected to the ground-side charging interface 1100, the image acquisition module 1400 is disposed opposite to the first surface 6212. Disposing the first signal module 6310 on the first surface 6212 ensures that the image acquisition module 1400 can identify the characteristic light source provided by the first signal module 6310 when the cover assembly 6200 is in the open position, and reduces the obstruction of recognition by various components disposed on the first base 6130, thereby improving the accuracy of recognition by the image acquisition module 1400.

[0095] In some embodiments, the first mating portion 6230 of the cover assembly 6200 is disposed on the first surface 6212, and at least a portion of the first mating portion 6230 protrudes from the first surface 6212; the first signal module 6310 includes at least two light-emitting elements, which are used to provide a feature light source. At least one light-emitting element is located on one side of the first mating portion 6230 along a first direction, and at least one light-emitting element is located on one side of the first mating portion 6230 along a second direction, wherein the first direction and the second direction are perpendicular. When the first mating portion 6230 protrudes from the first surface 6212, if a light-emitting element is only disposed on one side of the first mating portion 6230, the feature light source emitted by the light-emitting element may be blocked by the first mating portion 6230, affecting the recognition accuracy of the image acquisition module 1400. At least one light-emitting element is located on one side of the first mating part 6230 along the first direction, and at least one light-emitting element is located on one side of the first mating part 6230 along the second direction. This allows the first mating part 6230 to provide feature light sources from different sides, reducing or avoiding the first mating part 6230 from blocking the feature light sources, thereby improving the recognition accuracy and reliability of the image acquisition module 1400.

[0096] Example: The first signal module 6310 includes a first light-emitting element 6311, a second light-emitting element 6312, and a third light-emitting element 6313. The first and second light-emitting elements 6311 and 6312 are located on one side of the first mating portion 6230 along a first direction, and are spaced apart along a second direction, with different lengths along the second direction. The third light-emitting element 6313 is located on one side of the first mating portion 6230 along the second direction and has a columnar structure. A clearance cavity 6133 is provided on the first base 6130 to allow the third light-emitting element 6313 to pass through when the cover assembly 6200 is in the obstructed position. This configuration further improves the recognition effect of the image acquisition module 1400.

[0097] In some embodiments, the vehicle-side charging device 6000 is mounted on the bottom of the vehicle, and the ground-side charging device 1000 is mounted on the ground. Exemplarily, the ground connector is vertically and retractably mounted on the walking assembly 1500 so that the ground-side charging interface 1100 and the vehicle-side charging interface 6110 can vertically mate.

[0098] Thirdly, this application provides a vehicle that includes a vehicle-side charging device according to any of the above embodiments, the vehicle-side charging device being mounted on the bottom of the vehicle.

[0099] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0100] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
