Description

Technical Field

[0001] This application relates to the field of power equipment technology, and in particular to a power supply device, a connection component, a power transmission device, and a vehicle. Background Technology

[0002] Two compatible power supplies are typically used to achieve a detachable electrical connection. For example, one power supply may be configured as a socket and the other as a plug, so that the electrical connection between the lines they are connected can be established or terminated by plugging and unplugging.

[0003] In related technologies, to ensure safety, the power supply is equipped with a switching device. Users can use this device to switch the power supply's operating state, selectively placing it in a power transmission state or a safe state that isolates power transmission, thus ensuring user safety when the power supply is connected. However, if the power supply's operating state has not been switched to a safe state by the user when it is disconnected, it poses a significant safety risk to the user. Adding a structure to prevent the power supply from separating from the power source would be cumbersome in operation. Utility Model Content

[0116] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.

[0117] Reference Figures 1 to 22 As shown, the first aspect of this application provides a power supply 100 for supplying power to a power source 210. The power supply 100 can be combined with the power source 210 and forms an electrical connection with the power source 210. As a specific example, the power supply 100 is, for example, a socket 220, and the power source 210 is, for example, a plug 211 that is plugged into the socket 220.

[0118] Reference Figure 1 , Figure 2 and Figure 3 As shown, the power supply 100 includes a switching device 110, a locking device 120, and an operating device 130. The switching device 110 is used to switch the operating state of the power supply 100. The locking device 120 is used to lock the connection state of the power supply 100 and the power take-off device 210.

[0119] In practical applications, the switching device 110 may be used, for example, to control the on / off state of power transmission and / or signal transmission between the socket 220 and the plug 211. The locking device 120 may be used to lock the plug 211 onto the socket 220 to prevent the plug 211 from separating from the socket 220, thereby ensuring electrical safety. The operating device 130 may be a user-operated component used to control the switching device 110 to control the electrical connection between the plug 211 and the socket 220, such as a button, knob, etc., or other forms, which are not limited in this application.

[0120] The operating device 130 is used to control the switching device 110 and the locking device 120. That is, the operating device is used to switch the operating state of the power supply 100 using the switching device 110, and to lock the engagement state of the power supply 100 and the power take-off 210. Both the switching device 110 and the locking device 120 are connected to the operating device 130 so that the locking of the locking device 120 is coordinated with the switching of the switching device 110.

[0121] It should be noted that, in this application, a transmission connection refers to two objects forming a transmission connection, where one object, when in motion, can drive the other object to move simultaneously. Their movements and speeds can be the same or different, and such movements include, but are not limited to, rotation. For example, the transmission connection between the operating device 130 and the switching device 110 means that the operating device 130, when active, can drive the switching device 110 to move simultaneously. They can be directly connected or indirectly connected through a third object. Specifically, the operating device 130 can influence the switching device 110 and the locking device 120 through its own actions. For example, the operating device 130 can drive the switching device 110 to switch the operating state of the power supply 100 through its own movement, and the operating device 130 can drive the locking device to lock the connection state of the power supply 100 and the power take-off device 210 through its own movement. This means that the operating device 130 can be linked with the switching device 110 and the locking device 120 for at least a portion of its own travel distance, and is not limited to the operating device 130 always being linked with the switching device 110 and the locking device 120 during use.

[0122] As an example, the operating device 130 may be configured for user operation to coordinate the locking of the locking device 120 with the switching of the switching device 110; that is, the user can control both the switching device 110 and the locking device 120 by operating the operating device 130. As a more specific example, when the power supply 100 functions as a socket 220 and can form an electrical connection with the plug 211, the operating device 130, in addition to controlling the on / off of power transmission and / or electrical signal transmission between the plug 211 and the socket 220, can also be used to control whether the plug 211 can be detached from the socket 220.

[0123] By adopting the above solution, the components used by the user to control the power supply 100 to turn on and off can be reused as a device for locking or unlocking devices connected to the power supply 100 (such as the plug mentioned above). This simplifies operation and the structure of the power supply 100. In some usage scenarios, with fewer steps, the power supply 100 can be locked to the power supply 210 before switching to a state where it does not supply power to the power source 210, preventing the power source 210 from detaching from the power supply 100 and improving safety.

[0124] As a specific description of the working mode, the working state includes the power supply state and the power outage state. When the power supply 100 is in a powered state, it supplies power to the power take-off device 210 connected to it, meaning that the connected power supply 100 and the power take-off device 210 are energized. The term "energized" in this application refers to the ability to transmit electrical energy and / or electrical signals between the power supply 100 and the power take-off device 210. When the power supply 100 is in a de-energized state, the power supply 100 and the power take-off device 210 are de-energized, meaning that the connected power supply 100 and the power take-off device 210 are de-energized. The term "de-energized" in this application refers to the inability to transmit electrical energy and / or electrical signals between the power supply 100 and the power take-off device 210. In other words, the switching device 110 can at least switch the power supply 100 between a powered state and a de-energized state, and the power transmission / signal transmission between the power supply base 140 and the power take-off device 210 can be initiated or interrupted.

[0125] Correspondingly, the engagement state includes the locked state. When the power supply 100 is in the locked state, the locking device 120 locks the power supply 100 and the tap 210 for engagement with the power supply 100 to prevent the power supply 100 and the tap 210 from separating. That is, the locking device 120 can at least keep the power supply 100 in the locked state and lock the tap 210 to the power supply 100.

[0126] Based on the aforementioned operating and locked states, the power supply 100 has at least a first operating mode. In the first operating mode, the power supply 100 is in a locked state and either in a power-on or power-off state. That is, while the power supply 100 and the power source 210 are locked, the power supply 100 and the power source 210 can be powered on or disconnected to meet the usage requirements of different scenarios. For example, the power source 210 can be powered on to the power supply base 140 and locked to the power supply 100 to ensure electrical safety.

[0127] In some embodiments, the coupled state of the power supply 100 also includes an unlocked state. When the power supply 100 is in the unlocked state, the locking device 120 unlocks the coupled power supply 100 and the power generator 210. That is, in the unlocked state, the power generator 210 can be detached from the power supply 100 or normally installed on the power supply base 140. Correspondingly, the power supply 100 also has a second operating mode; in the second operating mode, the power supply 100 is in the unlocked state and is either in a power supply state or a power-off state. That is, the power supply 100 and the power generator 210 can be powered on or disconnected when the power supply 100 and the power generator 210 are in the unlocked state to meet the usage requirements in different usage scenarios. For example, the power generator 210 can be disconnected from the power supply 100, and then the power generator 210 can be detached from the power supply 100.

[0128] As an example of the transmission connection between the operating device 130 and the locking device 120, at least a portion of the operating device 130 is movably connected to at least a portion of the locking device 120, such that the operating device 130 and the locking device 120 form the transmission connection. That is, during operation, the operating device 130 can engage with the locking device 120 for at least a certain stroke and have relative displacement with the locking device 120; specifically, at least a portion of the operating device 130 has a first operating position and a second operating position, such that when the operating device 130 moves at least between the first and second operating positions, it can apply a force to the locking device 120 to move it cooperatively. Thus, during operation, the operating device 130 can drive the locking device 120 to move for at least a certain stroke, thereby achieving cooperation between the locking device 120 and the operating device. When the user operates the operating device, locking and / or unlocking of the aforementioned engagement state can be achieved.

[0129] In a specific embodiment, the operating device 130 includes an operating element 131. The operating element 131 is configured to form a movable connection between the operating device 130 and the locking device 120.

[0130] When the operating member 131 is in the first operating position, it restricts the movement space of the locking device 120, thus keeping the locking device 120 locked in the connected state of the power supply 100. When the operating member 131 is in the second operating position, it releases the movement space of the locking device 120, thus releasing the locking device 120 from the connected state of the power supply 100. Therefore, by moving the operating member, the locking device 120 is moved, thereby changing its range of motion and enabling the switching of the aforementioned connected state. For example, by restricting the movement space of the locking device 120, the power take-off 210 is prevented from being removed from the power supply 100; and after releasing the movement space of the locking device 120, the locking device 120 no longer prevents the power take-off 210 from separating from the power supply 100.

[0131] In the specific design, the power supply unit 100 also includes a power supply base 140. The power supply base 140 is used to connect with the power take-off unit 210.

[0132] Taking the power supply 100 configured as a socket 220 as an example, the power supply base 140 can be regarded as the whole consisting of the housing 221 of the socket 220 and the conductor (not shown in the figure) provided on the housing 221. When the plug 211 is plugged into the socket 220, it is connected to the conductor. After the conductor is connected to the power supply, it can supply power to the plug 211.

[0133] In some embodiments, the operating device 130 is configured to adjust the operating mode of the power supply 100 by controlling its movement relative to the power supply base 140. That is, the operating device 130 is movably connected to the power supply base 140, and during the movement, it adjusts at least one of the switching device 110 and the locking device 120, thereby adjusting the operating state and engagement state of the power supply 100. This adjustment of at least the operating state and engagement state of the power supply 100 constitutes an adjustment of the operating mode of the power supply 100. Compared to schemes using electromagnetic control or similar methods, insulation can be ensured by limiting the materials used in the manufacturing of the operating device 130, making it safer to use.

[0134] Reference Figure 4 , Figure 5 and Figure 6As shown in the exemplary description of the specific structure of the locking device 120 cooperating with the operating member 131, the locking device 120 includes a locking member 121. The locking member 121 is movably disposed on the power supply base 140, having at least a locked position and an unlocked position relative to the power supply base 140. When the locking member 121 is in the locked position, it can engage with the power supply unit 210 for connection to the power supply base 140 to lock the power supply unit 210. When the locking member 121 is in the unlocked position, it can avoid the power supply unit 210 for connection to the power supply base 140. When the operating member 131 is in the first operating position, it stops the locking member 121 from moving from the locked position to the unlocked position; that is, the operating member 131 blocks the path of movement of the locking member 121, thus locking the locking member 121 and preventing the power supply unit 210 from separating from the power supply base 140.

[0135] As a specific plan, refer to Figure 5 As shown, at least one of the operating member 131 and the locking member 121 is provided with a guide surface 100a, which guides the locking member 121 from the unlocked position to the locked position when the operating member 131 is active. This configuration allows the locking member 121 and the operating member 131 to move in different directions, and the guide surface 100a is used to guide the movement of the locking member 121 when the operating member 131 moves, thereby locking the power supply 210. It is understood that this configuration is beneficial for rationally configuring the relative spatial positions of the various components on the power supply 100. In specific application scenarios such as the socket 220, it helps to ensure the structural stability of the product and limit the overall size of the product.

[0136] For more specific solutions, refer to Figure 5 As shown, the aforementioned guide surface 100a can be provided on both the operating member 131 and the locking member 121. That is, the guide surface 100a includes a first guide surface 131a formed on the operating member 131 and a second guide surface 121a formed on the locking member 121. Figure 5 In the specific implementation of the example, the operating member 131 is slidably disposed on the power supply base 140 in the vertical direction, and the locking member 121 is slidably disposed on the power supply base 140 in the horizontal direction. The first guide surface 131a and the second guide surface 121a are both set as inclined surfaces that are inclined in the vertical or horizontal direction. Thus, within at least one end of the stroke of the operating member 131 moving in the vertical direction, the first guide surface 131a can contact the second guide surface 121a and push the locking member 121 to move in the horizontal direction, thereby realizing the use of the operating member 131 to drive the locking member 121 to lock the power take-off device 210 attached to the power supply base 140.

[0137] For more specific solutions, refer to Figures 4 to 6As shown, the guide surface 100a can be a single plane, curved surface, angle, or other forms, and this application does not impose any restrictions on it.

[0138] When the operating member 131 is in the second operating position, the operating member 131 moves from the locked position to the unlocked position to avoid the locking member 121. That is, after the operating member 131 moves from the first operating position to the second operating position, it no longer blocks the locking member 121, so that the power take-off 210 can be removed from the power supply base 140, or the power take-off 210 can be installed on the power supply base 140 at this time.

[0139] Reference Figure 7 As shown, the locking member 121 can be a single integral part, or it can be a whole formed by connecting multiple parts, such as those in this application. Figures 3 to 6 This example illustrates a scheme where the locking element 121 and the operating element 131 cooperate, and the locking element 121 and the power take-off 210 cooperate, which are two independent parts that are fixed together as a whole.

[0140] The locking device 120 can also integrate more structures to achieve more functions, such as enabling the locking member 121 to be held in certain positions under certain circumstances, for example, referring to Figure 4 As shown, the locking device 120 further includes a first reset member 122. The first reset member 122 and the locking member 121 form a force-transmitting connection, causing the locking member 121 to tend to be in a locked or unlocked position relative to the power supply base 140.

[0141] This configuration keeps the locking member 121 in the locked position after the operating member 131 stops blocking the locking member 121, thus preventing the power source 210 from separating from the power supply base 140. That is, the locking member 121 can still provide resistance to the power source 210. In usage scenarios such as when the power source 210 is attached to the power supply base 140 and the electrical connection between the two is not connected, or when the electrical connection between the power source 210 and the power supply base 140 is disconnected but has not yet been removed from the power supply base 140, the locking member 121 can be used to maintain the relative position of the power source 210 and the power supply base 140.

[0142] It is understood that, under this specific implementation scheme, the locking member 121 locking the power source 210 should be considered as the locking member 121 providing resistance to the power source 210, making it difficult to remove from the power supply base 140, rather than the locking member 121 locking the mounting component. That is, for different usage scenarios, the locking member 121 locking the power source 210 used to connect to the power supply base 140 can take at least one of the following forms: locking the power source 210, providing resistance to the power source 210 to prevent the power source 210 from separating from the power supply base 140.

[0143] Or, refer to Figure 4and Figure 5 As shown, after the operating member 131 stops blocking the locking member 121, the first reset member 122 drives the locking member 121 to move to the unlocked position, which facilitates the installation and removal of the power take-off device 210.

[0144] As an example of a specific solution, the first reset member 122 is configured as a first reset spring 122a disposed between the locking member 121 and the power supply base 140. It should be noted that the first reset spring 122a here is not limited to a spring in the conventional sense; in some application scenarios, the first reset spring 122a can also be interpreted as a tension spring.

[0145] The power supply 100 may include a plurality of locking elements 121; the plurality of locking elements 121 are adapted to engage with different portions of the power supply base 140 when in the locked position, thereby increasing the number of mating portions between the locking elements 121 and the power supply 210 and improving the stability of the connection of the power supply 210 to the power supply 100.

[0146] In the specific plan, refer to Figure 6 As shown, the locking member 121 includes a first locking member 121b and a second locking member 121c, both of which are rotatably connected to the power supply base 140. The operating member 131 is located between the first locking member 121b and the second locking member 121c. When the operating member 131 moves, it drives the first locking member 121b and the second locking member 121c to move, thereby locking the power take-off device 210 installed on the power supply base 140.

[0147] In other specific implementations, a partial locking member 121 is slidably connected to the power supply base 140, and a partial locking member 121 is rotatably connected to the power supply base 140. For example, in... Figure 7 In the specific embodiment shown, the first locking member 121b is slidably disposed on the power supply base 140 in the left-right direction shown in the figure, while the second locking member 121c is rotatably disposed on the power supply base 140. Both locks engage with corresponding portions of the power take-up device 210 for connection to the power supply base 140 when the operating member 131 moves, thus locking the power take-up device 210 installed on the power supply base 140. That is, the connection between the locking member 121 and the power supply base 140 includes at least one sliding connection and a rotating connection, and can be specifically configured according to the spatial position of each component on the power supply base 140 to facilitate the integration of the locking member 121 onto the power supply unit 100.

[0148] In a specific embodiment, the locking device 120 further includes a transmission member 123. This transmission member 123 is disposed between two dissimilar locking members 121 to facilitate a transmission connection between them. For example, see... Figures 4 to 6 As shown, a transmission member 123 is provided between the first locking member 121b and the second locking member 121c. When the first locking member 121b moves to the right in the left-right direction shown in the figure, the transmission member 123 moves with the first locking member 121b and thereby drives the second locking member 121c to rotate relative to the power supply base 140. The first locking member 121b and the second locking member 121c can lock the power take-off device 210 on the power supply base 140.

[0149] When the power take-off unit 210 is removed from the power supply base 140, the first return spring 122a drives the second locking member 121c to reset, thereby resetting the transmission member 123 and the second locking member 121c.

[0150] In a more specific embodiment, the transmission component 123 can be configured to be integrally formed with at least one of the locking components 121, so that when the locking component 121 is driven to reset by the first reset component 122, the transmission component 123 can be reset synchronously, thereby reducing the overall number of components on the power supply 100.

[0151] It should be noted that when multiple locking elements 121 are provided, the provision of the transmission element 123 is not necessarily required. For example, in Figure 7 , Figure 8 , Figure 9 and Figure 10 In the specific implementation of the example, the first locking member 121b and the second locking member 121c are respectively disposed on both sides of the operating member 131 along the front-back direction shown in the figure. When the operating member 131 moves, it drives the first locking member 121b and the second locking member 121c to move, thereby locking the power take-off device 210. In this specific implementation, the transmission member 123 mentioned above is not used. That is, the setting of the transmission member 123 can be flexibly configured according to the specific structure of the locking device 120.

[0152] In some embodiments, refer to Figure 11 As shown, the power supply 100 also includes a protection device 150. The protection device 150 is used to prevent the power supply 100 from switching its operating state when the power supply 100 is separated from the power take-off 210. That is, when the power take-off 210 is not connected to the power supply 100, the operating state of the power supply 100 can be limited by the protection device 150.

[0153] In some practical application scenarios, by setting up the protection device 150, the power supply 100 can be prevented from being in a power supply state when the power tap 210 is not installed on the power supply 100, that is, the conductor on the power supply base 140 is not energized, which can improve the safety of the power supply 100.

[0154] As an example, refer to Figure 12As shown, the protection device 150 includes a protection member 151. The protection member 151 is movably disposed on the power supply base 140 so as to have at least a protected position and a released position relative to the power supply base 140. When the protection member 151 is in the protected position, the protection member 151 stops the operating member 131 to prevent the operating member 131 from moving from the first operating position to the second operating position. When the protection member 151 is in the released position, the protection member 151 releases the stop on the operating member 131. That is, the safety of the power supply base 140 is ensured by the movement of the protection member 151. When the power supply unit 100 is configured as a socket 220, the protection member 151 can be correspondingly disposed at the slot 221a of the socket 220 for the plug 211 to be inserted.

[0155] More specifically, refer to Figure 13 As shown, the protective member 151 is provided with a mating part 151a. The mating part 151a is located on the engagement path of the power take-off 210 to the power supply base 140. It is moved to the disengaged position by the movement of the power take-off 210. That is, during the process of the power take-off 210 engaging with the power supply base 140, the mating part 151a is moved by contacting it, thereby releasing the restriction of the protective member 151 on the operating member 131. (Refer to...) Figure 13 and Figure 14 As shown, the mating part 151a is configured, for example, as an inclined surface 151b formed on the surface of the protective member 151, so that it is guided by the contactor 210 when it contacts the contactor 210, thereby moving the protective member 151.

[0156] In some embodiments, refer to Figure 12 As shown, the protection device 150 further includes a second reset member 152. The second reset member 152 and the locking member 121 form a force-transmitting connection to facilitate bringing the protection member 151 into a protected position. More specifically, the second reset member 152 can be configured, for example, as a second reset spring 152a disposed between the locking member 121 and the power supply base 140. By providing the second reset member 152, the protection member 151 can be reset after the power take-off 210 is removed from the power supply base 140, providing electrical protection for the power supply base 140. The second reset spring 152a is not limited to a spring in the conventional sense; in some applications, the second reset spring 152a can also be interpreted as a tension spring.

[0157] In some embodiments, refer to Figure 2 and Figure 11 As shown, the power supply 100 also includes a circuit board (not shown) and a signal terminal 153. The circuit board is mounted on the power supply base 140 and electrically connected to the switching device 110, suitable for controlling the switching device 110 and thus controlling the on / off switching of power transmission or electrical signal transmission between the power supply base 140 and the power take-off device 210. The signal terminal 153 is movably connected to the power supply base 140.

[0158] Signal terminal 153 is disposed on power supply base 140. Signal terminal 153 is adapted to form an electrical connection with the power take-off device 210 connected to power supply 100, and signal terminal 153 forms a connection with circuit board for transmitting electrical signals. In the specific embodiment shown in the figure, a terminal corresponding to signal terminal 153 can be provided on plug 211. This terminal contacts signal terminal 153 after plug 211 is plugged into socket 220, enabling the transmission of electrical signals between plug 211 and socket 220. In some usage scenarios, this can be used to determine whether plug 211 and socket 220 are properly paired, serving as the basis for switching device 110 to switch the operating state of power supply 100 to supply power to plug 211 from socket 220. In some usage scenarios, signal terminal 153 can also be used to feed back information such as current on plug 211 to circuit board, so that circuit board can determine whether plug 211 is faulty and cut off power supply in time when a fault occurs, thereby ensuring electrical safety.

[0159] Alternatively, other methods can be used to ensure the safety of the power supply 100. For example, refer to... Figures 15 to 20 As shown, the power supply 100 also includes a limiting device 160. The limiting device 160 is used to prevent the power tap 210 from connecting to the power supply base 140 when the power supply 100 is in a working state capable of supplying power to the power tap 210. The term "power supply 100 in a working state capable of supplying power to the power tap 210" as used in this application refers to the power supply 100 being ready to supply power to the power tap 210. For example, the power supply 100 is already in the aforementioned power supply state, connecting the conductors on the power supply base 140 to an external power source. In this working state, if the power tap 210 is properly installed on the power supply base 140, the power supply 100 can supply power to the power tap 210.

[0160] In some usage scenarios, such as when the power supply 100 is energized but the power take-up device 210 is not connected to the power supply base 140, the installation of the power take-up device 210 on the power supply base 140 can be prevented by setting a limit device 160, thus avoiding danger during the installation process.

[0161] As an example of a specific solution, refer to Figure 15 and Figure 16 As shown, the limiting device 160 includes a limiting member 161. The limiting member 161 is movably disposed on the power supply base 140 along a first direction so as to have at least a limiting position and an engaging position relative to the power supply base 140; specifically, when the limiting member 161 is located in one of the limiting position and the engaging position, it is at least partially located on the engaging path from which the power take-up device 210 engages with the power supply base 140.

[0162] As an example, refer to Figure 15 and Figure 16As shown, taking the power supply base 140 as the socket 220 and the power take-off device 210 as the plug 211, with the plug 211 inserted downwards into the socket 220 as shown in the diagram, when the limiting member 161 is in the limiting position, at least part of its body is in the path of the plug 211 moving downwards and being inserted into the socket 220. That is, when the plug 211 is installed, it is blocked by the limiting member 161 and cannot properly connect with the socket 220. In the usage scenario where the socket 220 is already powered on, it can prevent the plug 211 from being inserted. When the limiting member 161 is in the connecting position, it avoids the power take-off device 210 connected to the power supply base 140. That is, when the limiting member 161 moves to the connecting position, its body no longer blocks the insertion of the plug 211, and the plug 211 can be installed normally. Therefore, the movement of the limiting member 161 can protect the safety of the plug 211 when it draws power.

[0163] To achieve the movement of the limit component 161, refer to Figure 17 As shown, the limiting member 161 is provided with a guide slope 161a, which is adapted to contact the power take-up device 210 that moves toward the power supply base 140 to engage with the power supply base 140, and the limiting member 161 moves under the guidance of the power take-up device 210. Figure 18 In the specific implementation of the example, the guide slope 161a is inclined in the vertical direction and comes into contact with the plug 211 during the process of plug 211 being inserted downward into socket 220. Under the push of plug 211, the limiting member 161 moves from the limiting position to the engagement position, and the plug 211 can normally draw power.

[0164] It is understandable that if the limiting member 161 can move freely, the power supply 210 can still be connected to the power supply base 140 normally. Therefore, the movement of the limiting member 161 can be restricted, thereby further hindering the connection between the power supply 210 and the power supply base 140 in some usage scenarios.

[0165] As an example, refer to Figure 15 , Figure 16 and Figure 18 As shown, the limiting device 160 further includes a blocking member 162, wherein the blocking member 162 is movably disposed on the power supply base 140 along a second direction different from the first direction so as to have at least a blocking position and a movable position relative to the power supply base 140. Specifically, when the blocking member 162 is in the blocking position, it stops the limiting member 161 located in the limiting position to prevent the limiting member 161 from moving; when the blocking member 162 is in the engaging position, it avoids the limiting member 161. Thus, by moving the blocking member 162, the movement of the limiting member 161 can be restricted, thereby completely preventing the engagement of the power take-off device 210 with the power supply base 140 in some usage scenarios.

[0166] exist Figure 15 and Figure 16In the specific implementation of the example, the first direction is shown as the front-back direction in the diagram, and the second direction is shown as the left-right direction in the diagram. (Refer to...) Figure 16 As shown, when the blocking member 162 moves to the right to the blocking position, it prevents the limiting member 161, which is located in the limiting position, from moving forward, thereby preventing the plug 211 from engaging with the socket 220. (Refer to...) Figure 15 As shown, when the blocking member 162 is in the active position, it no longer blocks the limiting member 161, and the limiting member 161 can move to the engagement position so that the plug 211 and the socket 220 can be properly engaged.

[0167] Understandably, after the power take-off 210 is detached from the power supply base 140, the limiting member 161 can return to the limiting position to provide protection. To achieve this, refer to... Figure 18 As shown, a third reset member 163 can be provided between the limiting member 161 and the power supply base 140. This third reset member 163 is adapted to apply a force to the limiting member 161 to cause the limiting member 161 to tend to be in the limited position. Specifically, the third reset member 163 can be configured as, for example, a third reset spring 163a disposed between the power supply base 140 and the limiting member 161. The second reset spring 152a is not limited to a spring in the conventional sense; in some applications, the second reset spring 152a can also be interpreted as a tension spring.

[0168] In some embodiments, refer to Figure 15 , Figure 16 , Figure 19 and Figure 20 As shown, when the limiting member 161 is in the engaged position, it stops the blocking member 162, which is in the movable position. This arrangement restricts the movement of the blocking member 162, ensuring the normal operation of the limiting device 160 in some usage scenarios. Specifically, the limiting device 160 also includes an elastic member 164. This elastic member 164 is disposed between the locking member 121 and the blocking member 162 to facilitate the transmission of force between the locking member 121 and the blocking member 162. Thus, in some usage scenarios, the movement of the blocking member 162 is linked to the movement of the locking member 121.

[0169] Reference Figure 15 As shown, when the socket 220 and plug 211 are engaged, during the process of the locking member 121 moving to the right in the left-right direction to lock the plug 211, the elastic member 164 transmits force, causing the blocking member 162, which is in the movable position, to tend to move to the right. Since the limiting member 161 is in the engaged position at this time, the blocking member 162 cannot move normally, and the elastic member 164 allows the locking member 121 to move normally through its own deformation. After the plug 211 and socket 220 are separated, refer to... Figure 16As shown, when the limiting member 161 moves to the limiting position, if the operating member 131 moves downward to energize the socket 220, the locking member 121 is driven to move to the right. The elastic member 164 drives the blocking member 162 to move to the right to the blocking position, thus blocking the limiting member 161. Therefore, when the socket 220 is energized, the plug 211 cannot be properly plugged into the socket 220. The elastic member 164 can be connected to the locking member 121 and the blocking member 162 by means of welding, so that when the locking member 121 wants to move, it can drive the blocking member 162 to move to the left. Of course, the connection method is only an example and not the only limitation.

[0170] Reference Figure 19 and Figure 20 As shown, this specific plan is similar to Figure 15 The difference in the illustrated scheme is that a clearance groove 161b is formed on the limiting member 161, which is adapted to allow at least a portion of the blocking member 162 to be inserted so that the blocking member 162 can move normally. In this scheme, refer to... Figure 19 As shown, at this time, the limiting member 161 is in the limited position and the blocking member 162 is in the movable position. When the moving operating member 131 causes the locking member 121 to move the blocking member 162 to the blocking position, the blocking member 162 is embedded in the relief groove 161b, which can prevent the limiting member 161 from moving backward, thereby locking the limiting member 161. The power take-up device 210 cannot complete the connection with the power supply base 140. (Refer to...) Figure 20 As shown, when the blocking member 162 is in the active position, the power take-up device 210 is connected to the power supply base 140, causing the limiting member 161 to move to the position shown in the figure (i.e., the connected position). At this time, when the user operates the aforementioned operating member 131, the blocking member 162 and the locking member 121 move relative to each other due to the setting of the elastic member 164, without hindering the normal movement of the locking member 121.

[0171] In the specific design, the elastic element 164 is configured as a connecting spring 164a located between the locking element 121 and the blocking element 162. The connecting spring 164a is not limited to a spring in the conventional sense; in some applications, the connecting spring 164a can also be interpreted as a tension spring.

[0172] The following mainly describes some aspects of the cooperation between the switching device 110 and the operating device 130. As an example of the transmission connection between the switching device 110 and the operating device 130, at least a portion of the switching device 110 is fixedly connected to at least a portion of the operating device 130, so that the operating device 130 and the switching device 110 form a transmission connection, and the operating device 130 can apply a coordinating force to the switching device 110 when moving at least between a first operating position and a second operating position. That is, by being directly or indirectly fixed to the switching device 110, the operating device 130 can drive at least a portion of the switching device 110 to move within at least a certain stroke of its movement. Thus, the operating device 130 and the switching device 110 form a transmission connection, realizing the coordination between the movement of the operating device 130 and the activity of at least a portion of the switching device 110, thereby switching the aforementioned working state through this displacement coordination.

[0173] As an exemplary description of the specific structure of the switching device 110, refer to Figure 20 As shown, the switching device 110 includes a power switch 111. The power switch 111 is configured as part of a fixed connection between the switching device 110 and the operating device 130; that is, at least a portion of the power switch 111 is connected to the operating member 131 via a transmission connection, for controlling the on / off state of power transmission and / or electrical signal transmission between the combined power supply 100 and the power take-off 210 when the operating member 131 is active. Specifically, when the power supply 100 is configured as a socket 220, the power switch 111 can be a switch that controls whether the conductor supplying power to the plug 211 on the socket 220 is energized.

[0174] The power switch 111 has at least a first operating state and a second operating state; when the power switch 111 is in the first operating state, it connects the power transmission and / or electrical signal transmission between the combined power supply 100 and the power take-off 210; when the power switch 111 is in the second operating state, it disconnects the power transmission and / or electrical signal transmission between the combined power supply 100 and the power take-off 210.

[0175] The operating element 131 can be configured as part of a fixed connection between the operating device 130 and the switching device 110, meaning the operating element 131 can be directly or indirectly fixedly connected to the power switch. When the operating element 131 is in the first operating position, it causes a first displacement by driving at least a portion of the power switch 111, thus placing the power switch 111 in a first operating state. Specifically, when the operating element 131 moves to the first operating position, the corresponding movement of at least a portion of the power switch 111 is the first displacement. Within this stroke, the power transmission and / or electrical signal transmission between the power supply base 140 and the power take-off device 210 is connected, thereby achieving coordination between the movement of the operating element 131 and the connection of the power supply 100 to the power take-off device 210.

[0176] Furthermore, under the specific cooperation configuration of the aforementioned operating member 131 and locking device 120, when the power switch 111 is working to enable the power supply base 140 to be energized with the power source 210, the locking device 120 locks the power source 210 when the operating member 131 is in the first operating position, which can ensure the electrical safety of the power source 210 and the power supply base 140.

[0177] In some embodiments, when the operating member 131 is in the second operating position, the operating member 131 causes the power switch 111 to be in the second use state by a second displacement generated by driving at least a portion of the power switch 111. That is, when the operating member 131 moves to the second operating position, the corresponding movement amount of at least a portion of the power switch 111 is the second displacement. Within this stroke, the power transmission and / or signal transmission between the power supply base 140 and the power take-off device 210 is disconnected, thereby realizing the coordination of the movement of the operating member 131 and the disconnection of the power supply 100 from the power take-off device 210.

[0178] Furthermore, under the specific cooperation mode of the aforementioned operating member 131 and locking device 120, when the power switch 111 is in the second use state, the locking device 120 unlocks the power supply 210 when the operating member 131 is in the second operating position, so that the power supply 210 can be normally removed from the power supply base 140 after the power supply 210 is de-energized.

[0179] In the specific design, the switching of the operating state of the power switch can be achieved by shifting two relatively movable conductive contacts within the power switch. One conductive contact is directly or indirectly connected to the operating element 131. When the operating element 131 moves, it contacts or moves away from the other conductive contact. The two conductive contacts can each be connected to a conductive structure (e.g., a wire), thus creating an electrical connection between the two conductive structures when the two conductive contacts are in contact. When the conductive structure is connected to a power source, the two conductive contacts are energized, which is the first operating state mentioned above. Conversely, if the operating element 131 moves and separates the two conductive contacts, the power is de-energized between the two conductive contacts, which is the second operating state mentioned above.

[0180] As a specific plan, refer to Figure 21 and Figure 22 As shown, the operating device 130 may further include a self-locking switch 132, which enables the operating member 131 to remain in a first operating position or a second operating position, allowing the power switch 111 to continuously control the power supply base 140 and the power take-off device 210 to be energized or de-energized. This application does not impose specific limitations on the specific structure of the self-locking switch 132; as an example, refer to... Figure 22 As shown, the self-locking switch 132 can adopt a structure similar to that of a push-button automatic ballpoint pen that controls the extension or retraction of the pen tip into the pen holder, or the self-locking switch 132 can adopt... Figure 23 The self-locking buckle shown is commonly seen in products such as lockable flip-top trash cans, and its specific structure will not be described in detail here; or the self-locking switch 132 can be integrated with the power switch 111 as a whole in the form of a push-button switch, etc.

[0181] In a more specific embodiment, a structure such as a spring can be provided between the operating member 131 and the power supply base 140 for resetting, so that the operating member 131 can tend to be held in the first operating position or the second operating position, so that the operating member 131 can work normally.

[0182] Based on the above solutions, a second aspect of this application also provides a connection component 200, including a power source 210 and the aforementioned power supply 100, wherein the power source 210 is combined with the power supply 100 to form an electrical connection with the power supply 100. This connection component 200 has the beneficial effects of the aforementioned power supply 100, which will not be elaborated upon here.

[0183] In a specific design, the power supply 100 can be configured as a socket 220, and correspondingly, the power source 210 can be configured as a plug 211 that connects to the socket 220.

[0184] It should be noted that the socket 220 can be provided with multiple positions for plugs 211 to be inserted, that is, the socket 220 can supply power to multiple plugs 211. The power switch 111 can be used to control the power on and off between the socket 220 and all plugs 211, or it can be used only to control the power on and off between the socket 220 and some plugs 211, while the use of other plugs 211 is not affected.

[0185] In some embodiments, refer to Figure 5 As shown, the plug 211 is provided with a fitting structure 211c. The fitting structure 211c is used to engage with the locking device 120 to lock the plug 211 onto the socket 220. In a specific embodiment, the fitting structure 211c can engage with the aforementioned locking member 121 in the locked position to lock the plug 211, and when the locking member 121 is in the unlocked position, the fitting structure 211c disengages from the locking member 121, allowing the plug 211 to be removed from the socket 220.

[0186] In some embodiments, the fitting structure 211c is configured as a fitting groove 211d formed on the plug 211, that is, the locking device 120 can lock the plug 211 by being embedded in the fitting groove 211d.

[0187] According to a third aspect of this application, a power transmission device 10 is also provided, including a discharge gun and the aforementioned connecting assembly 200. The discharge gun is connected to the power take-off device 210 of the connecting assembly 200. This discharge gun can be used, for example, for charging new energy vehicles. Of course, in other specific application scenarios, the plug 211 can also be configured to be combined with electrical equipment such as computer hosts, servers, fans, and chargers, so that after the plug 211 is inserted into the socket 220, power is supplied to the electrical equipment using the plug 211 and the socket 220.

[0188] According to the third aspect of this application, referring to Figure 24 As shown, a vehicle 1 is also provided, including the power supply 100 described above, or the connection component 200 described above, or the power transmission device 10 described above. This vehicle 1 possesses all the beneficial effects of the power supply 100, the connection component 200, or the power transmission device 10 described above, which will not be elaborated further here.

[0189] The vehicle 1 can be a gasoline-powered vehicle, a plug-in hybrid electric vehicle, or a new energy vehicle, etc., and this application does not make any specific restrictions on it.
