Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of charging equipment, in particular to a charging gun and a charging equipment. BACKGROUND

[0002] The charging gun is used for plug-in cooperation with a charging interface of a device to be charged (such as an electric vehicle) to charge the device to be charged.

[0003] In order to improve the charging efficiency of the charging gun, more charging pins can be arranged on the charging gun to improve the power transmission efficiency of the charging gun, and thus improve the charging efficiency of the charging gun. For example, the MCS (Megawatt Charging System) interface defined based on the national standard is realized by adding a pair of power terminals directly below the existing DC charging interface of the charging gun defined based on the national standard. Therefore, compared with the charging gun equipped with the DC charging interface, the charging efficiency of the charging gun equipped with the MCS interface is higher. In addition, the charging gun is usually provided with other structures such as a locking rod, a fastener and the like on the side of the MCS interface, which makes the side of the MCS interface on the charging gun occupy a larger space and affects the use of the user. CONTENT OF THE UTILITY MODEL

[0004] The present application provides a charging gun and a charging equipment, which aims to make the structure of the charging gun more compact, thereby reducing the occupied space of the charging gun.

[0005] To achieve the above-mentioned purpose, the present application adopts the following technical solutions:

[0006] In a first aspect, the present application provides a charging gun, which comprises a gun body, a first pair of power terminals and a second pair of power terminals. The gun body comprises a containing space and a first end face, and the first end face comprises a through hole. The cable connection end of the first pair of power terminals and the cable connection end of the second pair of power terminals are located in the containing space. The plug-in end of the first pair of power terminals and the plug-in end of the second pair of power terminals extend outside the gun body through the through hole.

[0007] Among them, the two terminals of the first pair of power terminals are arranged in the width direction of the charging gun; the two terminals of the second pair of power terminals are arranged in the width direction of the charging gun, and the first pair of power terminals and the second pair of power terminals are arranged in the height direction of the charging gun. The maximum size of the first end face in the height direction of the charging gun is D1, and the maximum size of the first end face in the width direction of the charging gun is D2,

[0008] In some use scenarios of the charging gun, the cable connection end of the first pair of power terminals and the cable connection end of the second pair of power terminals of the charging gun are located in the accommodation space of the gun body for connection with the cable in the accommodation space of the gun body, the cable transmits current to the first pair of power terminals and the second pair of power terminals, the plug-in end of the first pair of power terminals and the plug-in end of the second pair of power terminals extend outside the gun body for connecting the electric vehicle, and the current of the first pair of power terminals and the current of the second pair of power terminals can be transmitted to the electric vehicle to charge the electric vehicle.

[0009] The two terminals of the first pair of power terminals are arranged in the width direction of the charging gun, the two terminals of the second pair of power terminals are arranged in the width direction of the charging gun, and the first pair of power terminals and the second pair of power terminals are arranged in the height direction of the charging gun. In some examples, the first pair of power terminals and the second pair of power terminals can be connection terminals of the MCS interface defined based on the national standard.

[0010] The height direction and the width direction of the charging gun can be understood as follows: when a user faces the first end surface of the charging gun, the up-down direction of the user is the height direction of the charging gun, and the left-right direction of the user is the width direction of the charging gun. The maximum size of the first end surface in the height direction of the charging gun can be understood as follows: the first end surface has two opposite edges in the height direction of the charging gun, and the maximum value of the distance between the two edges is the maximum size of the first end surface in the height direction of the charging gun. Similarly, the maximum size of the first end surface in the width direction of the charging gun can be understood as follows: the first end surface has two opposite edges in the width direction of the charging gun, and the maximum value of the distance between the two edges is the maximum size of the first end surface in the width direction of the charging gun.

[0011] In the charging gun provided in the present application, by limiting the value of to between 1.5 (inclusive) and 2.0 (inclusive), the occupied space of the first end surface of the charging gun is limited. For example, when the first pair of power terminals and the second pair of power terminals are connection terminals of the MCS interface defined based on the national standard, i.e., the charging gun includes the MCS interface defined based on the national standard, because the size of the MCS interface is a standard value specified by the national standard, by limiting the value of to between 1.5 (inclusive) and 2.0 (inclusive), the occupied space of other structures (such as lock rods, fasteners, etc.) on the first end surface in addition to the MCS interface defined based on the national standard can be limited, and the MCS interface defined based on the national standard and other structures (such as lock rods, fasteners, etc.) arranged on the first end surface are more compact, which is beneficial to reducing the occupied space and weight of the charging gun and facilitating user use.

[0012] In an optional embodiment, the gun body has a holding space, and the gun body comprises a handle, a first side wall, a second side wall, and a third side wall, and the handle, the first side wall, the second side wall, and the third side wall enclose the holding space. The handle is provided with a fourth side wall on the side facing the holding space. The first side wall and the second side wall are oppositely arranged in the length direction of the handle. The third side wall and the fourth side wall are oppositely arranged in the height direction of the handle.

[0013] When the user holds the handle, the user's hand can be inserted into the holding space and hold the handle, so that the user can stably hold the handle. The provision of the holding space can facilitate the user to hold the handle, for example, the ergonomic holding space can enable the user's palm and fingers to naturally adhere to the handle, reducing the user's fatigue after holding the charging gun for a long time, and can also reduce the weight of the charging gun.

[0014] In some embodiments, the distance between the first side wall and the second side wall is 90-150 mm, which can be understood as the length dimension of the holding space, that is, when the user holds the handle, the size of the user's hand that can be inserted into the holding space in the length direction of the holding space is 90-150 mm, so that the length dimension of the holding space is more in line with the ergonomic requirements, and the user's hand can be easily inserted to improve the user's holding comfort.

[0015] In some embodiments, the distance between the third side wall and the fourth side wall is 30-50 mm, which can be understood as the height dimension of the holding space, that is, when the user holds the handle, the size of the user's hand that can be inserted into the holding space in the height direction of the holding space is 30-50 mm, so that the height dimension of the holding space is more in line with the ergonomic requirements, and the user's hand can be easily inserted to improve the user's holding comfort.

[0016] In other embodiments, the distance between the first side wall and the second side wall is 90-150 mm, and the distance between the third side wall and the fourth side wall is 30-50 mm, that is, when the user holds the handle, the size of the user's hand that can be inserted into the holding space in the length direction of the holding space is 90-150 mm, and the size of the user's hand that can be inserted into the holding space in the height direction of the holding space is 30-50 mm, so that the length dimension and the height dimension of the holding space are more in line with the ergonomic requirements, and the user's hand can be easily inserted to improve the user's holding comfort.

[0017] In an optional embodiment, the handle is provided with a fifth side wall on the side away from the holding space, and the distance between the fourth side wall and the fifth side wall is 30-50 mm.

[0018] The size of the handle in the height direction of the handle itself is 30-50 mm. The height direction of the handle can be understood as the thickness direction of the palm of the user when the palm of the user faces the fifth side wall, that is, the height direction of the handle. When the user holds the handle, the height of the handle that can be held by the user's hand is 30-50 mm, so that the height of the handle meets the ergonomic requirements, and the user can hold the handle stably and comfortably, improving the holding comfort of the user.

[0019] In an optional embodiment, the size of the handle in the width direction of the handle itself is 30-50 mm.

[0020] The width direction of the handle can be understood as the width direction of the palm of the user when the palm of the user faces the fifth side wall, that is, the width direction of the handle. When the user holds the handle, the width of the handle that can be held by the user's hand is 30-50 mm, so that the width of the handle meets the ergonomic requirements, and the user can hold the handle stably and comfortably, improving the holding comfort of the user.

[0021] In an optional embodiment, the gun body has a second end face through which the cable passes, and the distance between the second side wall and the second end face is 30-50 mm.

[0022] In this way, the handle is close to the center of gravity of the charging gun, so that the user can easily and freely hold and operate the charging gun, reduce hand fatigue, and easily keep the balance and stability of the charging gun. The part of the cable passing through the second end face and extending outside the gun body is used to connect an external power supply device, and the part of the cable passing through the second end face and extending into the gun body is used to power the first and second pairs of cable terminals.

[0023] In an optional embodiment, the vertical distance between the third side wall and the bottom wall of the gun body is 75-95 mm.

[0024] The vertical distance between the third side wall and the bottom wall of the gun body can be understood as the minimum distance between the bottom wall of the end of the gun body away from the first end face and the third side wall. By making the vertical distance between the third side wall and the bottom wall of the gun body 75-95 mm, on the one hand, the space of the accommodation space in the gun body can be ensured to facilitate the arrangement and connection of the internal elements of the gun body, and on the other hand, the handle can be closer to the center of gravity of the charging gun, so that the user can easily and freely hold and operate the charging gun, reduce hand fatigue, and easily keep the balance and stability of the charging gun.

[0025] In an optional embodiment, the bottom wall of the gun body is bent, and the included angle at the bent portion is 140-150°.

[0026] The bottom wall of the gun body is bent, so that the charging gun is more ergonomic, is convenient for the user to hold and operate, and can reduce the hand fatigue of the user during charging. In addition, the bottom wall of the gun body is bent, so that the charging gun can adapt to a narrow charging environment, so that the user can easily complete the charging operation and the plugging and unplugging operation without needing to adjust the position of the charging gun too much, thereby avoiding the situation that the plugging and unplugging is difficult due to the limited charging environment. In addition, since electric vehicles can have different charging interface positions, the bottom wall of the gun body is bent to adapt to different charging interface positions, so as to ensure that the gun head of the charging gun can be successfully docked with the charging interface.

[0027] In an optional embodiment, the gun body comprises a first gun shell, an end cover and a fastener, the surface of the end cover away from the first gun shell is a first end face, and the fastener is connected with the first gun shell through the end cover. The first end face comprises an annular structure surrounding the plug-in end of the second pair of power terminals. The outer circumferential surface of the annular structure is provided with a relief groove for the fastener to pass through.

[0028] By using the relief groove, the fastener and the second pair of power terminals can be arranged more compactly, that is, the fastener and the MCS interface defined based on the national standard are arranged more compactly, thereby facilitating the reduction of the occupied space and the weight of the first end face. In addition, the provision of the relief groove can reduce the weight of the annular structure, thereby reducing the weight of the charging gun. In addition, the relief groove can also provide a guiding effect for the installation of the fastener, thereby facilitating the connection of the fastener with the end cover and the first gun shell.

[0029] In an optional embodiment, the first end face comprises a protruding structure, the protruding structure, the first pair of power terminals and the second pair of power terminals are arranged at intervals along the height direction of the charging gun, and the end portion of the protruding structure away from the first end face is bent along the height direction of the charging gun.

[0030] Since the charging interface of the electric vehicle is provided with a groove, the end portion of the protruding structure away from the first end face is bent along the height direction of the charging gun, and the bent portion can be connected with the groove, so as to prevent the gun head from being disconnected from the charging interface of the electric vehicle during charging, thereby ensuring the safety and stability of the charging process.

[0031] The arrangement of the protruding structure, the first pair of power terminals and the second pair of power terminals at intervals along the height direction of the charging gun on the first end face can facilitate the connection of the protruding structure with the groove of the charging interface when the charging gun is connected with the electric vehicle, and can also help to realize the compactness of the structure of the charging gun, so that the entire charging gun looks more beautiful and neat.

[0032] In this example, the protruding structure can extend into the gun body through the first end surface for connecting with components in the gun body, such as connecting with the keys of the charging gun. Part of the protruding structure is located on the first end surface and part of the protruding structure is located in the gun body, which can make the structure of the charging gun more compact and further improve the appearance of the charging gun.

[0033] In an alternative embodiment, the size of the first end surface in the width direction of the charging gun gradually decreases in the direction in which the second pair of power terminals faces the first pair of power terminals.

[0034] It can be understood that the first end surface has two opposite edges in the width direction of the charging gun, and the distance between the two edges gradually decreases in the direction in which the second pair of power terminals faces the first pair of power terminals.

[0035] In some scenarios, the first pair of power terminals and the second pair of power terminals are connection terminals of an MCS interface defined based on a national standard. The plug-in end of the first pair of power terminals and the plug-in end of the second pair of power terminals are located in a ring-shaped structure, such as a first ring-shaped structure and a second ring-shaped structure. The first ring-shaped structure surrounds the plug-in end of the second pair of power terminals, and the second ring-shaped structure surrounds the plug-in end of the first pair of power terminals. The size of the second ring-shaped structure in the width direction of the charging gun is smaller than the size of the first ring-shaped structure in the width direction of the charging gun. In addition, the side of the second ring-shaped structure away from the second pair of power terminals is a flat surface, and the size of the flat surface of the second ring-shaped structure in the width direction of the charging gun is smaller than the size of other positions of the second ring-shaped structure in the width direction of the charging gun.

[0036] In addition, the size of the protruding structure in the width direction of the charging gun is smaller than the size of the ring-shaped structure surrounding the plug-in end of the first pair of power terminals in the width direction of the charging gun. By limiting the size of the first end surface in the width direction of the charging gun gradually decreasing in the direction in which the second pair of power terminals faces the first pair of power terminals, the occupied space of the first end surface can be reduced, which is beneficial to reduce the cost and weight of the charging gun.

[0037] In a second aspect of the present application, a charging gun is provided, which includes a gun body having a holding space. The gun body includes a handle, a first side wall, a second side wall, and a third side wall, which enclose the holding space. The handle is provided with a fourth side wall on the side facing the holding space. The first side wall and the second side wall are oppositely arranged in the length direction of the handle. The third side wall and the fourth side wall are oppositely arranged in the height direction of the handle.

[0038] When the user holds the handle, the user's hand can be inserted into the holding space and hold the handle, so that the user can stably hold the handle. The holding space is provided, on the one hand, to facilitate the user to hold the handle, for example, the ergonomic holding space can make the user's palm and fingers naturally fit on the handle, reducing the user's fatigue after holding the charging gun for a long time, and on the other hand, the weight of the charging gun can be reduced.

[0039] In some embodiments, the distance between the first side wall and the second side wall is 90mm-150mm, which can be understood as the length dimension of the holding space, that is, when the user holds the handle, the size of the user's hand that can be inserted into the holding space in the length direction of the holding space is 90mm-150mm, so that the length dimension of the holding space is more in line with the ergonomic requirements, and the user's hand can be inserted more conveniently, improving the user's holding comfort.

[0040] In some embodiments, the distance between the third side wall and the fourth side wall is 30mm-50mm, which can be understood as the height dimension of the holding space, that is, when the user holds the handle, the size of the user's hand that can be inserted into the holding space in the height direction of the holding space is 30mm-50mm, so that the height dimension of the holding space is more in line with the ergonomic requirements, and the user's hand can be inserted more conveniently, improving the user's holding comfort.

[0041] In some embodiments, the distance between the first side wall and the second side wall is 90mm-150mm, and the distance between the third side wall and the fourth side wall is 30mm-50mm, that is, when the user holds the handle, the size of the user's hand that can be inserted into the holding space in the length direction of the holding space is 90mm-150mm, and the size of the user's hand that can be inserted into the holding space in the height direction of the holding space is 30mm-50mm, so that the length dimension and the height dimension of the holding space are more in line with the ergonomic requirements, and the user's hand can be inserted more conveniently, improving the user's holding comfort.

[0042] In an alternative embodiment, the fifth side wall is arranged on the side of the handle away from the holding space, and the distance between the fourth side wall and the fifth side wall is 30mm-50mm.

[0043] The size of the handle in the height direction of the handle is 30mm-50mm. The height direction of the handle can be understood as the thickness direction of the user's palm when the palm is opposite to the fifth side wall, that is, the height direction of the handle. When the user holds the handle, the size of the handle that can be held by the user's hand is 30mm-50mm, so that the height dimension of the handle is more in line with the ergonomic requirements, and the user can stably and comfortably hold the handle, improving the user's holding comfort.

[0044] In an optional embodiment, the handle has a dimension of 30-50 mm in the width direction of the handle.

[0045] The width direction of the handle can be understood as the width direction of the user's palm when the user's palm is opposite the fifth side wall. When the user holds the handle, the width of the handle that the user's hand can hold is 30-50 mm, so that the width of the handle meets the ergonomic requirements, and the user can hold the handle stably and comfortably, improving the user's holding comfort.

[0046] In an optional embodiment, the gun body has a second end face through which the cable passes, and the distance between the second side wall and the second end face is 30-50 mm.

[0047] In this way, the handle is close to the center of gravity of the charging gun, so that the user can easily and comfortably hold and operate the charging gun, reduce hand fatigue, and easily keep the balance and stability of the charging gun. The part of the cable that passes through the second end face and extends outside the gun body is used to connect an external power supply device, and the part of the cable that passes through the second end face and extends into the gun body is used to power the connecting end of the charging gun.

[0048] In an optional embodiment, the vertical distance between the third side wall and the bottom wall of the gun body is 75-95 mm.

[0049] The vertical distance between the third side wall and the bottom wall of the gun body can be understood as the minimum distance between the bottom wall of the end of the gun body away from the first end face and the third side wall. By making the vertical distance between the third side wall and the bottom wall of the gun body 75-95 mm, on the one hand, the space in the gun body can be ensured to facilitate the arrangement and connection of internal elements, and on the other hand, the handle is close to the center of gravity of the charging gun, so that the user can easily and comfortably hold and operate the charging gun, reduce hand fatigue, and easily keep the balance and stability of the charging gun.

[0050] In an optional embodiment, the bottom wall of the gun body is bent, and the included angle at the bent portion is 140-150°.

[0051] The bottom wall of the gun body is bent, so that the charging gun meets the ergonomic requirements, is convenient for the user to hold and operate, and can reduce the user's hand fatigue during charging.

[0078] In other examples, the charging device 100 can not include the housing 30. The power module 20 can be arranged in other devices and connected with the charging gun 10 through the cable. The specific arrangement position of the power module 20 and the structure of the charging device 100 are not limited in the present application.

[0079] The embodiments of the present application further provide a charging gun 10 that can be applied in the charging device described above. Figure 2 The structure of the charging gun 10 is exemplarily shown. Referring to Figure 2The charging gun 10 can include a gun body 1 and a gun head 2. The gun body 1 has a first end face 111. The gun head 2 includes a first annular structure 21 and a second annular structure 22, which are arranged on the first end face 111.

[0080] In some examples, a part of the gun head 2 can be arranged on the first end face 111, for example, the first annular structure 21 and the second annular structure 22 can be located on the first end face 111 for connecting the electric vehicle, and the rest of the gun head 2 can pass through the first end face 111 and be located in the gun body 1 for connecting the elements and cables inside the charging gun 10. The gun body 1 can protect the elements inside itself, such as anti-collision, waterproof, insulation, etc., and can improve the appearance of the charging gun 10 by designing the shape of the gun body 1.

[0081] In some examples, the gun body 1 includes a first gun shell 13 and an end cover 11, and the end cover 11 is connected to the first gun shell 13. The end cover 11 covers the entire end of the first gun shell 13. The surface of the end cover away from the first gun shell 13 is the first end face 111.

[0082] In this example, the end cover 11 can be connected to the first gun shell 13 in any suitable manner, for example, the end cover 11 is connected to the first gun shell 13 by a plurality of fasteners, which is not limited in the present application.

[0083] In other examples, referring to Figure 2 The gun body 1 includes a first gun shell 13, an end cover 11, and an upper cover 17.

[0096] Referring toFigure 5 In some examples, the first end surface 111 of the charging gun 10 is provided with other structures in addition to the gun head 2, such as the protruding structure 4, the fastener 3, etc.

[0097] In order to reduce the occupied space of the first end surface 111 of the charging gun 10, by making the value of between 1.5 (inclusive) and 2.0 (inclusive), other structures on the first end surface 111 in addition to the MCS interface defined based on the national standard, such as the protruding structure 4, the fastener 3, etc., can be limited in the occupied space of the first end surface 111, so that the MCS interface defined based on the national standard and other structures, such as the protruding structure 4, the fastener 3, etc., are arranged more compactly on the first end surface 111, which is beneficial to reduce the occupied space and weight of the charging gun 10 and facilitate user use.

[0098] In some examples, The value of can be 1.669, can also be 1.5, can also be 2.0, or any value between 1.5 and 2.0, which is not specifically limited in the present application.

[0099] Referring to Figure 5 , the outer periphery of the first annular structure 21 is provided with an avoidance slot 222 for the fastener 3 to pass through. In this example, the avoidance slot 222 can make the fastener 3 and the second pair of power terminals 221 arranged more compactly, i.e., the fastener 3 and the MCS interface defined based on the national standard are arranged more compactly, which is beneficial to reduce the occupied space and weight of the first end surface 111. In addition, the provision of the avoidance slot 222 can reduce the weight of the first annular structure 21, and in turn reduce the weight of the charging gun 10. In addition, the avoidance slot 222 can also provide a guiding effect for the installation of the fastener 3.

[0100] The number and arrangement position of the avoidance slot 222 on the first annular structure 21 can be designed according to actual needs, which is not specifically limited in the present application.

[0101] In some examples, the outer periphery of the second annular structure 22 can also be provided with an avoidance slot for the fastener 3 to pass through, so as to further reduce the occupied space of the first end surface 111. The number and arrangement position of the avoidance slot on the second annular structure 22 can be designed according to actual needs, which is also not specifically limited in the present application.

[0102] In some examples, the fastener 3 can be a bolt, which includes a head and a rod portion, one end of the rod portion is connected to the head, and the other end is connected to the first gun shell 13 through the cover 11. Wherein, the head of the bolt is at least partially located in the avoidance slot 222.

[0103] Referring to Figure 5The size of the protruding structure 4 on the first end surface 111 in the width direction of the charging gun 10 is smaller than the size of the first annular structure 21 and the second annular structure 22 in the width direction of the charging gun 10. The size of the second annular structure 22 in the width direction of the charging gun 10 is smaller than the size of the first annular structure 21 in the width direction of the charging gun 10. And the side of the second annular structure 22 away from the first annular structure 21 is a flat surface, and the size of the flat surface of the second annular structure 22 in the width direction of the charging gun 10 is smaller than the size of other positions of the second annular structure 22 in the width direction of the charging gun 10.

In some examples, referring to Figure 5 , so that the size of the first end surface 111 in the width direction of the charging gun 10 gradually decreases in the direction of the second pair of power terminals 221 towards the first pair of power terminals 211, that is, the distance between the two second edges 1112 gradually decreases in the direction of the second pair of power terminals 221 towards the first pair of power terminals 211, thereby achieving the purpose of reducing the occupied space of the first end surface 111, and facilitating the reduction of the cost and weight of the entire charging gun 10.

[0105] In some examples, referring to Figure 5 , the protruding structure 4, the second annular structure 22 and the first annular structure 21 are arranged in sequence in the height direction of the charging gun 10, which on the one hand can make the connection of the protruding structure 4 and the groove of the charging interface (such as the groove 201 of the charging interface 200 shown in Figure 4 ) of the electric vehicle more convenient when the charging gun 10 is connected with the electric vehicle, and on the other hand helps to realize the compactness of the structure of the charging gun 10, so that the entire charging gun 10 looks more beautiful and neat.

[0106] Figure 6 An exemplary schematic diagram of the internal structure of the charging gun 10 is shown. Referring to Figure 6 , in this example, a part of the protruding structure 4 can be located on the first end surface 111, for example, the end of the protruding structure 4 away from the first end surface 111 is bent along the height direction of the charging gun 10, such as bent towards the second annular structure 22 along the height direction of the charging gun 10, to form a locking tongue. The locking tongue formed by the bending of the protruding structure 4 can be connected with the groove of the charging interface (such as the groove 201 of the charging interface 200 shown in Figure 4 ) of the electric vehicle to prevent the gun head 2 from being disconnected from the electric vehicle during charging, ensuring the safety and stability of the charging process.

[0107] The end of the protruding structure 4 away from the bending part can pass through the first end surface 111 and extend into the gun body 1 for connection with the components in the gun body 1, so that the structure of the charging gun 10 is more compact, and the appearance is further improved.

[0108] For example, refer to Figure 6 The gun body 1 is provided with a button 18, which is connected to the end of the protruding structure 4 away from the bend. The center of the protruding structure 4 is rotatably mounted on the rotating shaft so that the protruding structure 4 forms a lever structure.

[0109] The user presses button 18, which presses down the end of the protruding structure 4 away from the bend, so that the end of the protruding structure 4 away from the first end face 111 is upward in the height direction of the charging gun 10. Figure 6 The upper part of the diagram moves, causing the latch formed at the bend of the protruding structure 4 to engage with the groove of the electric vehicle's charging port (as shown in the diagram above). Figure 4 The recess 201 of the charging interface 200 shown is disengaged, allowing the user to plug and unplug the charging gun 10 relative to the electric vehicle.

[0110] When the user releases button 18, button 18 can move upwards. For example, a spring is provided below button 18, with one end of the spring abutting against button 18 and the other end abutting against the inner wall of the gun body 1. The elastic force of the spring itself can push button 18 upwards. The upward movement of button 18 can cause the end of the protruding structure 4 away from the bend to move upwards until it is flush with the end of the protruding structure 4 away from the first end face 111. That is, the locking tongue formed at the bend of the protruding structure 4 moves downwards, which can be used to make the locking tongue formed at the bend of the protruding structure 4 fit into the groove of the charging interface of the electric vehicle (e.g., Figure 4 The groove 201 of the charging interface 200 shown is used for connection.

[0111] Reference Figure 6 The gun body 1 includes a receiving space 01, a part of the gun head 2 is located in the receiving space 01, and a part of it extends out of the gun body 1 through a through hole 1113 on the first end face 111.

[0126] In some examples, the gun body 1 includes a tail cover arranged on the side of the gun body 1 away from the gun head 2, and the second end surface 12 is formed on the side of the tail cover away from the gun head 2.

[0127] In some examples, the cable of the charging gun 10 extends into the gun body 1 through the tail cover to connect the terminal of the gun head 2. In some examples, the tail cable clamping structure of the cable at the tail cover is arranged inside the gun body 1 to realize a hidden design of the tail cable clamping structure and improve the appearance of the charging gun 10.

[0128] Referring to Figure 7 , the gun body 1 includes a bottom wall 141, that is, the side wall closest to the bottom of the gun body 1 in the height direction of the charging gun 10 is the bottom wall 141. The distance between the third side wall 144 and the bottom wall 141 is d5, which can be 75 mm to 95 mm. On the one hand, this can ensure the space of the accommodation space in the gun body 1 to facilitate the arrangement and connection of the internal elements of the gun body 1, and on the other hand, it can make the handle 16 closer to the center of gravity of the entire charging gun 10, so that the user can easily hold and operate the charging gun 10, reduce hand fatigue, and easily keep the charging gun 10 balanced and stable.

[0129] In some examples, the distance d5 between the third side wall 144 and the bottom wall 141 can be 75 mm, 82 mm, 95 mm, or any value between 75 mm and 95 mm, which is not limited in the present application.
