These drawings and the accompanying description are not intended to limit the scope of the present invention in any way, but rather to illustrate the concept of the present invention to those skilled in the art by reference to specific embodiments. DETAILED DESCRIPTION

[0087] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0088] The directional nouns involved in the embodiments of the present invention, such as "upper", "lower", "side", "front", "back", etc., are generally expressed in the form of Figure 1 The relative relationship of the directions shown in the figure is used as a reference, and these directions are used only to more clearly describe the relationship between structures, not to describe absolute directions. When the product is placed in different postures, the directions may change, for example, "up" and "down" may be interchangeable. Figure 1 For example, the position of the button is defined as up, the position of the gun head is defined as front, and the position of the gun tail is defined as back.

[0089] Unless otherwise defined, all technical terms used in the embodiments of the present invention have the same meanings as those commonly understood by those skilled in the art. To make the technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0090] At present, the charging gun with an indicator light provided by the relevant technology usually has a mounting cavity provided on the top of the shell of the charging gun, and the charging indicator light is tightly assembled in the mounting cavity, that is, the outer shell of the charging indicator light is tightly against the inner wall of the mounting cavity. Despite this, there may still be a tiny gap between the charging indicator light and the mounting cavity that is invisible to the naked eye. Water, dust and other impurities can easily penetrate into the interior of the charging gun through the tiny gap, thereby affecting the service life of the charging gun and causing safety hazards.

[0091] In order to solve the technical problem that the charging gun in the related art has poor waterproof and dustproof properties, the embodiment of the present invention provides a charging gun, as shown in the attached Figure 1 and attached Figure 2 As shown, the charging gun includes: a gun body 001, a gun head 002 and a cable 004. The gun head 002 is connected to the front end of the gun body 001, the first end of the cable 004 is electrically connected to the gun head 002, and the second end of the cable 004 extends from the rear end of the gun body 001.

[0092] The gun body 001 includes: a gun body shell 11, a button 12 exposed on the gun body shell 11, a locking member 13 located inside the gun body shell 11, a pressure plate 14, a base 15, a circuit board 161 and at least one indicator light 162; Figure 3 As shown, the button 12, pressure plate 14, and base 15 abut against each other from top to bottom. The locking member 13 is hinged to the pressure plate 14 and abuts against the button 12. A first seal 171 is provided at the abutment between the button 12 and pressure plate 14, and a second seal 172 is provided at the abutment between the pressure plate 14 and base 15. At least one indicator light 162 is electrically connected to a circuit board 161, which is electrically connected to a cable 004. The circuit board 161 and the at least one indicator light 162 are both located between the pressure plate 14 and base 15. Light emitted by the indicator light 162 is transmitted to the outside through the pressure plate 14 and button 12.

[0093] The charging gun provided in an embodiment of the present invention comprises a cable 004, a circuit board 161, and an indicator light 162, which are sequentially electrically connected and disposed within the gun housing 11. When the charging gun is powered and in a charging state, the indicator light 162 illuminates to indicate that the charging gun is currently connected to and charging a powered device. A first seal 171 is provided at the junction between the button 12 and the pressure plate 14, and a second seal 172 is provided at the junction between the pressure plate 14 and the base 15. These first and second seals 171 and 172 seal the flow channel between the gun housing 11 and the outside world, effectively blocking tiny gaps that are invisible to the naked eye. Thus, the circuit board 161 and indicator light 162 are located within the enclosed space between the pressure plate 14 and the base 15, effectively preventing safety issues such as water and dust intrusion that could cause the charging gun to fail, significantly improving the charging gun's waterproof and dustproof sealing properties.

[0094] In addition, the indicator light 162 is located inside the gun body shell 11 and the light it emits is transmitted to the outside through the pressure plate 14 and the button 12, making the structure of the charging gun more compact and also conducive to the miniaturization of the charging gun.

[0095] The following is an exemplary description of the structure and function of each component included in the gun body 001 of the charging gun:

[0096] Regarding the base 15 , in an embodiment of the present invention, the base 15 is fixed inside the gun body shell 11 . In some examples, the gun body shell 11 has a first accommodating cavity 111 (for example, the first accommodating cavity 111 is provided at the top of the gun body shell 11 ), and the button 12 is located in the first accommodating cavity 111 .

[0097] Furthermore, as attached Figure 3 As shown, a connecting skirt 113 is provided inside the first accommodating cavity 111 , and an opening 1130 is formed on the connecting skirt 113 ; the base 15 is fixed on the connecting skirt 113 , and a portion of the bottom of the base 15 is exposed to the opening 1130 .

[0098] The connecting skirt 113 is located at the bottom of the first accommodating cavity 111 to support and fix the base 15. The bottom of the base 15 fixed on the connecting skirt 113 is partially exposed at the opening 1130, so that the cable can be assembled through the opening 1130 and connected to the circuit board 161 on the base 15 (see Figure 1 ).

[0099] Ways of fixing the base 15 between the connecting skirt plates 113 include, but are not limited to: screw connection, bonding, clamping, riveting, or pressing the base 15 onto the connecting skirt plates 113 by means of a pressing plate 14 .

[0100] The base 15 is used to support and accommodate the circuit board 161. In some examples, the base 15 has a positioning groove, and the circuit board 161 is accommodated and positioned in the positioning groove.

[0101] Combine Figure 1 and Figure 5 It can be seen that in order to make the circuit board 161 inside it waterproof and dustproof, a second seal 172 is provided between the base 15 and the pressure plate 14, wherein the second seal 172 is clamped between the top peripheral side of the base 15 and the bottom peripheral side of the pressure plate 14, so that the two cooperate to form a closed space to accommodate the circuit board 161 and the indicator light 162.

[0102] In some examples, a sealing groove is provided on the top circumference of the base 15. It is understood that the sealing groove is provided around the periphery of the positioning groove and may be further located above the positioning groove. The second sealing member 172 is accommodated in the sealing groove to achieve positioning of the second sealing member 172. In this case, the second sealing member 172 can be designed in the form of a sealing ring.

[0103] Regarding the pressing plate 14, in the embodiment of the present invention, the pressing plate 14 is pressed on the top of the base 15 and is hinged to the locking member 13 to provide support thereto. In order to allow the light of the indicator light 162 below the pressing plate 14 to be smoothly transmitted through the pressing plate 14, as shown in the attached Figure 4 As shown, the pressure plate 14 includes a plate body 141 and a light guide portion 142. The light guide portion 142 is convexly arranged on the side of the plate body 141 facing the button 12. The light guide portion 142 has a light guide cavity 1420. The light guide cavity 1420 is used to converge the light emitted by the indicator light 162; Figure 5 As shown, the first sealing member 171 is located between the button 12 and the light guide portion 142 , and the second sealing member 172 is located between the plate portion 141 and the base 15 .

[0104] In some examples, the side of the plate body 141, the side of the base 15, and the connecting skirt 113 are abutted and fixed in sequence, wherein the plate body 141 can be fixedly connected to at least one of the base 15 and the connecting skirt 113, so that the bottom peripheral side of the plate body 141 abuts against the top peripheral side of the base 15, and the fixed connection method between the plate body 141 and the base 15 and / or the connecting skirt 113 includes but is not limited to: screw connection, bonding, clamping or riveting, etc.

[0105] In some examples, such as the attached Figure 4 As shown, a connecting block 1410 is provided on the side of the plate body 141 , the connecting block 1410 is connected to the connecting skirt 113 , and the base 15 is pressed tightly between the plate body 141 and the connecting skirt 113 .

[0106] This method has the advantages of saving space and simple assembly. The connection between the connecting block 1410 and the connecting skirt 113 can be screw connection, bonding, clamping or riveting.

[0107] For example, if Figure 6 As shown, the connecting block 1410 on the plate body 141 is connected to the connecting skirt 113 by a fastening screw 18, and a positioning block 150 is provided at a corresponding position on the side of the base 15, and the positioning block 150 is provided with a closed screw hole or a semi-open screw hole for the fastening screw 18 to pass through.

[0108] The screws simultaneously penetrate the connecting block 1410 of the plate body 141 and the positioning block 150 on the base 15 and are connected to the connecting skirt 113 on the gun body shell 11 via the fastening screws 18. In this way, the base 15 is pressed between the plate body 141 and the connecting skirt 113, and due to the mutual stop of the positioning block 150 and the fastening screws 18, the base 15 is further positioned and will not undergo unexpected horizontal displacement.

[0109] In order to improve the connection effect, a screw column can be set on the connecting skirt 113 to increase the length of the internal thread so that the fastening screw 18 is connected to the screw column. Furthermore, the fastening screws 18 can be set to two or more symmetrically, and multiple fastening screws 18 can be evenly spaced.

[0110] The light-guiding portion 142 is through-through from top to bottom, and is formed by connecting the side panels end to end. The side panels are arranged to form a light-guiding cavity 1420. The lower end of the side panel is connected to the plate body 141 and communicates with the light-guiding port opened on the plate body 141. The upper end of the side panel abuts against the bottom wall of the button 12.

[0111] The shape of the light guide 142 is determined by the distribution of the indicator lights 162. For example, if multiple indicator lights 162 are arranged in a straight line along the horizontal direction, the light guide 142 can be designed as a long strip. The light guide 142 can not only focus and guide the light emitted by the indicator lights 162, but also be designed to be high enough to abut the bottom wall of the button 12 at a corresponding position.

[0112] The first seal 171 is arranged between the bottom wall of the button 12 and the top wall (i.e., the upper port) of the light guide portion 142. In some examples, the first seal 171 is connected to the bottom wall of the button 12 and formed as a whole. In this way, the button 12 abuts against the upper port of the light guide portion 142 through the first seal 171, so that the button 12 is in sealed contact with the light guide portion 142.

[0113] As mentioned above, the locking member 13 is hinged to the pressure plate 14. In some examples, such as the attached Figure 4As shown, the pressure plate 14 also includes two bracket portions 144, which are arranged on both sides of the plate body 141 relatively, for example, the two bracket portions 144 are arranged in the middle of both sides of the plate body 141, wherein the bracket portions 144 are provided with an axial hole to accommodate the pin shaft 137, and the pin shaft 137 is used to realize the hinge between the locking member 13 and the pressure plate 14.

[0114] In some implementations, such as the attached Figure 1 and attached Figure 5 As shown, the gun body 001 involved in the embodiment of the present invention further includes: a switch 163, which is electrically connected to the circuit board 161 and is located above the circuit board 161. The switch 163 is protruded on the side of the circuit board 161 facing the pressure plate 14, that is, the switch 163 is located above the circuit board 161.

[0115] In the embodiment of the present invention, the functions of the switch 163 include but are not limited to: being used to power on or off the charging gun, being used to automatically open the charging port protective cover on the body of the electric vehicle, etc., which are not specifically limited here.

[0116] Furthermore, combined with Figure 4 As shown, the pressure plate 14 also includes: a receiving portion 143 connected to the plate body 141, the receiving portion 143 is protruding from the side of the plate body 141 facing the pressing portion 1223, and the receiving portion 143 has a through hole; the main body of the switch 163 is located in the receiving portion 143, and a third sealing member 173 is provided between the main body of the switch 163 and the receiving portion 143; the telescopic head of the switch 163 passes through the through hole and abuts against the locking member 13.

[0117] In some examples, the light guide portion 142 and the receiving portion 143 are respectively located on either side of the bracket portion 144. The receiving portion 143 is similar to a cap and is provided with a via hole, for example, the via hole is opened on the top wall of the receiving portion 143. The main body of the switch 163 is located inside the receiving portion 143, and the telescopic head of the switch 163 passes through the via hole to the top of the receiving portion 143.

[0118] In order to improve the sealing performance, the inner cavity of the accommodating portion 143 and the external flow channel are blocked, as shown in the attached Figure 5 As shown, a third sealing member 173 can be disposed between the outer wall of the switch 163 and the inner wall of the accommodating portion 143. In some examples, the third sealing member 173 is cap-shaped, and the top of the third sealing member 173 is also provided with a through hole for the telescopic head of the switch 163 to pass through. In this way, the third sealing member 173 simultaneously covers the top and sides of the main body of the switch 163 and abuts against the top and sides of the inner wall of the accommodating portion 143, providing a multi-directional seal and improving the sealing effect.

[0119] It can be seen that the third sealing member 173 is provided to seal the tiny gap between the switch 163 and the pressure plate 14 to ensure that external water, dust, etc. will not enter between the pressure plate 14 and the base 15, thereby preventing interference with the circuit board 161 and the indicator light 162.

[0120] As described above, the gun body portion 001 involved in the embodiment of the present invention also includes: a switch 163, which is electrically connected to the circuit board 161 and is located above the circuit board 161. The switch 163 is used to power on or off the charging gun. The switch 163 is protruding from the side of the circuit board 161 facing the pressure plate 14.

[0121] Furthermore, as attached Figure 6 As shown, the button 12 has a pressable pressing portion 1223, combined with Figure 5 It can be seen that the pressing portion 1223, the locking member 13, and the telescopic head of the switch 163 are abutted in sequence; the charging gun is configured to switch the locking member 13 between the locked position and the unlocked position by pressing the pressing portion 1223, and at the same time, switch the switch 163 between the closed state and the open state.

[0122] Switch 163 is a microswitch. The pressing portion 1223 of button 12, the locking member 13, and the retractable head of switch 163 sequentially abut against each other. When the locking member 13 is in the locked position, switch 163 is correspondingly closed, energizing the charging gun and enabling it to charge the device while locked. Conversely, after charging is complete, pressing the pressing portion 1223 to switch the locking member 13 to the unlocked position triggers switch 163, switching from the closed state to the open state. This de-energizes the charging gun and unlocks it, allowing it to be removed from the device.

[0123] It can be seen that by linking the button 12, the locking piece 13 and the switch 163, the charging gun is locked during charging, and the power is cut off when the charging gun is not performing the charging action, thereby ensuring the safety of the charging gun after it is pulled out, improving the safety of the charging gun, and making it easier for users to operate with one hand, thereby improving the user experience.

[0124] In the embodiment of the present invention, the circuit board 161, the indicator light 162, and the switch 163 are integrated into one body and designed as a light board assembly.

[0125] The locking member 13 locks the charging gun after it is inserted into the power receiving port of the powered device, allowing charging to proceed while locked. The structure of the locking member 13 has been modified accordingly based on the arrangement of the button 12, pressure plate 14, and base 15 in the embodiments of the present invention.

[0126] As attached Figure 6As shown, the locking member 13 includes: an abutting section 131 , a first transition section 132 , a hinge section 133 , a second transition section 134 and a locking section 135 which are connected in sequence.

[0127] Further integration Figure 7 It can be seen that the top wall of the abutting section 131 abuts against the pressing portion 1223 of the button 12 , and the corresponding position of the bottom wall of the abutting section 131 abuts against the telescopic head of the switch 163 .

[0128] An elastic member 136 is connected to the bottom wall of the end of the abutting section 131 away from the first transition section 132. This elastic member 136 is used to push up against the abutting section 131, ensuring that it always abuts against the pressing portion 1223 of the button 12. When the elastic member 136 is in its natural position, the locking member 13 is in the locked position, and the abutting section 131 is tilted upward relative to the locking section 135. When the pressing portion 1223 is pressed downward, the abutting section 131 moves downward, the locking section 135 moves upward, and the locking member 13 rotates to the unlocked position, while the elastic member 136 is compressed. When the user no longer presses the pressing portion 1223, the elastic member 136 returns to its original position and pushes the abutting section 131 upward, returning the locking member 13 to the locked position.

[0129] The elastic member 136 can be arranged in the gun body shell 11 in a variety of ways. In some examples, such as the attached Figure 5 As shown, the elastic member 136 is a compression spring. A protrusion is provided on the bottom wall of the end of the abutment section 131 away from the first transition section 132. One end of the elastic member 136 is tightly fitted over the protrusion. The other end of the elastic member 136 can be fitted over another protrusion on the base 15, or it can pass through the base 15 and fit over another protrusion on the connecting skirt 113 of the gun body shell 11. When the other end of the elastic member 136 passes through the base 15 and abuts the gun body shell 11, the compression stroke of the elastic member 136 is further extended.

[0130] It should be noted that, as mentioned above, the pressure plate 14 and the base 15 can be fixed to the connecting skirt 113 on the base 15 by the same screw. If there is a screw passing through the end of the pressure plate 14, an anti-interference groove or anti-interference hole can be provided at the corresponding position on the abutment section 131 of the locking member 13 to avoid interference with the screw.

[0131] The first transition section 132 is used to form a connection between the abutting section 131 and the hinge section 133. In some examples, the first transition section 132 can be designed as a hollow frame to increase the elasticity of the locking member 13 and make it lightweight.

[0132] As attached Figure 5-6As shown, the hinge section 133 is used to articulate with the pressure plate 14 via a pin 137. In some examples, the hinge section 133 is rod-shaped, with its length perpendicular to the first transition section 132 and the second transition section 134. A through hole extending along the axial direction of the hinge section 133 can be provided inside the hinge section 133, with the pin 137 extending through the through hole and its ends protruding from both ends of the hinge end. The two ends of the pin 137 protruding from the hinge section 133 are respectively sleeved into the axial holes of the bracket portion 144 of the pressure plate 14, thereby achieving the articulated connection between the locking member 13 and the pressure plate 14.

[0133] Furthermore, the bottom of the hinge section 133 is set to be arc-shaped, and a rotation groove portion 145 is set at a corresponding position on the plate body 141 of the pressing plate 14 (see Figure 4 ), the rotation groove portion 145 has an arc-shaped rotation groove, and the corresponding position of the arc-shaped bottom of the hinge section 133 is located in the arc-shaped rotation groove.

[0134] In some examples, the rotation groove portion 145 is located in the middle of the two bracket portions 144. With this arrangement, when the locking member 13 is driven to rotate by the button 12, the hinge section 133 can rotate under the guidance of the arc-shaped rotation groove, which not only makes the rotation of the locking member 13 smoother, but also improves the support stability of the locking member 13 by the pressure plate 14.

[0135] The second transition section 134 is used to connect the locking section and the hinge section 133 and allows the light guide 142 on the pressure plate 14 to pass through. In some examples, the second transition section 134 is designed as a hollow frame, the inner cavity of which is used to accommodate and pass through the light guide 142 of the pressure plate 14.

[0136] The locking section 135 is used to lock in the power receiving port of the power receiving device. The locking section 135 extends out of the side of the button 12 so that the lock on it can enter the power receiving port of the power receiving device. Figure 6 As shown, a lock is provided at the end of the lock segment 135 away from the second transition segment 134 , and correspondingly, a lock slot is provided at the power receiving port of the power receiving device, such as an electric vehicle, and the lock is adapted to engage with the lock slot.

[0137] According to the above structure of the locking member 13, the charging locking principle of the charging gun involved in the embodiment of the present invention can be as follows:

[0138] When charging a powered device, the gun head 002 is inserted into the electric vehicle's power port as a charging port. Simultaneously, the latch of the locking member 13 engages with the locking slot at the power port, locking the charging gun to the powered device and allowing charging to proceed. When charging is complete, the pressing portion 1223 of the button 12 is pressed, causing the locking member 13 to rotate, moving the latch upward and out of the locking slot, unlocking the gun and allowing it to be removed from the electric vehicle's power port.

[0139] The button 12 is assembled and exposed on the gun body housing 11, for example, exposed on the top of the gun body housing 11, and the button 12 can protrude above the gun body housing 11 or be flush with the gun body housing 11. By pressing the button 12, the locking member 13 and further the switch 163 are driven.

[0140] In some examples, such as the attached Figure 8 As shown, the gun body shell 11 has a first accommodating cavity 111 , the button 12 is located in the first accommodating cavity 111 , and a fourth sealing member 174 is provided between the outer wall of the button 12 and the inner wall of the first accommodating cavity 111 .

[0141] The fourth sealing member 174 can seal the tiny gap between the button 12 and the gun body housing 11 , effectively preventing impurities such as water and dust from entering the interior of the gun body housing 11 , further improving the waterproof and dustproof performance of the charging gun.

[0142] The fourth sealing member 174 can be independently disposed or integrally formed on the outer wall of the button 12. The independent fourth sealing member 174 can be in the form of a sealing ring, whose structure is compatible with the outer contour of the button 12. A sealing groove is provided on the outer wall of the button 12 or the inner wall of the first accommodating cavity 111, and the fourth sealing member 174 is accommodated within the sealing groove.

[0143] In some examples, such as the attached Figure 10 As shown, the fourth seal 174 is integrally formed on the outer wall of the button 12. For example, the button 12 includes a soft rubber layer 122 made of soft rubber material. By forming a circle of soft rubber protrusions on the outer wall of the soft rubber layer 122, the soft rubber protrusions can serve as the fourth seal 174. This method is more beneficial for improving the waterproof and dustproof properties of the button 12 and improving the assembly efficiency of the button 12.

[0144] The button 12 involved in the embodiment of the present invention must meet the following two conditions: having a light-transmitting area, and having a pressing portion 1223 that can be pressed up and down. All buttons 12 that meet the above conditions are applicable to the embodiment of the present invention.

[0145] As a typical example, the attached Figure 9 and attached Figure 10 As shown, the button 12 includes: a hard support layer 121 , a soft rubber layer 122 covering the outside of the hard support layer 121 , and a fourth sealing member 174 integrally formed on the outer wall of the soft rubber layer 122 . The fourth sealing member 174 is arranged around the soft rubber layer 122 .

[0146] The fourth sealing member 174 is a soft rubber protrusion and can be integrally formed on the outer side of the soft rubber layer 122 . The interference fit between the fourth sealing member 174 and the first accommodating cavity 111 effectively seals the gap between the soft rubber layer 122 and the gun body shell 11 .

[0147] For example, if Figure 8 As shown, the fourth sealing member 174 is in the form of an arcuate protrusion, and the arcuate end of the fourth sealing member 174 extends in a radial direction away from the soft rubber layer 122. That is, the fourth sealing member 174 is an arcuate soft rubber protrusion, and its arcuate end is used to abut against the inner side wall of the first accommodating cavity 111 of the gun body shell 11, thereby achieving an effective sealing connection between the button 12 and the gun body shell 11. Moreover, the arcuate end design is more advantageous for improving the sealing between the button and the gun body shell 11 than a flat structure.

[0148] Furthermore, as attached Figure 10 As shown, the hard support layer 121 includes a support body 1211 , a light-transmitting portion 1212 and a pressing hole 1213 on the support body 1211 . The soft rubber layer 122 includes a soft rubber body 1221 , a light-guiding hole 1222 and a pressing portion 1223 on the soft rubber body 1221 .

[0149] The light guide hole 1222 is opposite to the light-transmitting portion 1212, and the pressing portion 1223 is opposite to the pressing hole 1213. It is understandable that although the soft rubber layer 122 itself is entirely pressable, the presence of the hard support layer 121 makes only the portion of the soft rubber layer 122 opposite to the pressing hole 1213 on the hard support layer 121 pressable, and this portion is the pressing portion 1223.

[0150] The button 12 provided in this embodiment of the present invention utilizes a soft rubber layer 122 coated on a hard support layer 121, leveraging the elasticity of the soft rubber layer 122 to impart pressurization and sealing properties to the button 12. The portion of the soft rubber layer 122 opposite the press hole 1213 serves as a pressing portion 1223. This allows the pressing portion 1223 to be pressed unimpeded, thereby pressing and driving the abutting section 131 of the locking member 13.

[0151] Light guide holes 1222 are provided in the soft rubber layer 122, opposite the light-transmitting portion 1212, to ensure that light emitted from the light-transmitting portion 1212 is guided out of the button 12 without obstruction. It is understood that the structure of the light guide holes 1222 is compatible with that of the light-transmitting portion 1212. For example, both the light-transmitting portion 1212 and the light guide holes 1222 can be circular, strip-shaped, triangular, or other geometric shapes.

[0152] The hard support layer 121 serves as a frame supporting the button 12 and has a light-transmitting portion 1212 and a press hole 1213. The light-transmitting portion 1212 is made of a light-transmitting material and can transmit light emitted by the indicator light 162. The shape and size of the press hole 1213 are determined by the shape of the abutting section 131 of the locking member 13, so that the press hole 1213 can accommodate the abutting section 131 of the locking member 13, thereby allowing the abutting section 131 to abut against the press portion 1223 on the soft rubber layer 122.

[0153] In some examples, the hard support layer 121 is formed of a light-transmitting material to form the light-transmitting portion 1212 , and is formed of a non-light-transmitting material to form other portions except the light-transmitting portion 1212 .

[0154] In other examples, the entire hard support layer 121 is made of a light-transmitting material. Thus, the entire hard support layer 121 is light-transmitting, and the portion of the hard support layer 121 opposite the light-guiding hole 1222 in the soft rubber layer 122 serves as the light-transmitting portion 1212. This approach simplifies the preparation process of the hard support layer 121 and provides the hard support layer 121 with greater structural stability.

[0155] In some examples, the light-transmitting materials mentioned above are transparent materials. For example, the light-transmitting materials include but are not limited to: polycarbonate (PC), polymethyl methacrylate (PMMA), polyethylene terephthalate (PET), polypropylene (PP), polyvinyl chloride (PVC), polystyrene (PS), transparent nylon, etc. Among them, polycarbonate (PC) can be used to prepare the hard support layer 121 in the embodiments of the present invention based on its excellent strength and flexibility.

[0156] In some examples, such as the attached Figure 10 As shown, the light-transmitting portion 1212 is protruded from the side of the hard supporting layer 121 facing the soft rubber layer 122 (ie, the light-transmitting portion 1212 is located above the top wall of the hard supporting layer 121 ), and is sleeved inside the light-guiding hole 1222 in an interference fit manner.

[0157] The top wall of the light-transmitting portion 1212 can be higher than the top wall of the soft rubber layer 122, or it can be flush with the top wall of the soft rubber layer 122. By adopting an interference fit, the light-transmitting portion 1212 is tightly inserted into the light-guiding hole 1222, and the elastic characteristics of the soft rubber layer 122 are utilized to ensure good sealing and assembly stability between the two.

[0158] As can be understood, the light-transmitting portion 1212 includes light-transmitting side panels and a light-transmitting top wall. The lower ends of the light-transmitting side panels are connected to the top wall of the hard support layer 121, and the upper ends of the light-transmitting side panels are connected to the light-transmitting top wall. In the assembled state, the light-transmitting side panels are pressed against the inner sidewalls of the light-guiding aperture 1222, ensuring a tight fit. Light emitted by the indicator light 162 is transmitted through the light-transmitting top wall.

[0159] In some examples, such as the attached Figure 10 As shown, the support body 1211 includes a first side wall 12111 and a first top wall 12112 connected to the upper end of the first side wall 12111 , wherein the light-transmitting portion 1212 and the pressing hole 1213 are respectively arranged on both sides of the first top wall 12112 .

[0160] In some examples, the first side 12111 of the hard support layer 121 is connected to the base 15 , and the connection method therebetween includes, but is not limited to, at least one of screw connection, clamping, and riveting.

[0161] For example, the first side of the first side panel 12111 is snap-fitted to the corresponding side of the base 15, and the second side of the first side panel 12111 is screwed to the plug housing 21 of the charging head 002. The first side of the first side panel 12111 is the side away from the charging head 002, and the second side of the first side panel 12111 is the side closer to the charging head 002. This connection method effectively utilizes the internal space of the charging gun, ensuring a more compact structure while achieving a reliable connection.

[0162] As mentioned above, the first side of the first side enclosure 12111 engages with the corresponding side of the base 15. For example, a first hook can be provided on the inner wall of the first side enclosure 12111, and a second hook can be provided on the outer wall of the corresponding side of the base 15, with the first hook and the second hook being adapted to engage. When the button 12 is inserted into the first accommodating cavity 111 of the gun body housing 11, the first hook moves downward along the guide surface on the second hook and presses against the second hook until the button 12 is fully assembled, the second hook returns to its original position, and the first hook and the second hook engage.

[0163] The second side of the first side panel 12111 is connected to the plug housing 21 of the gun head 002 by screws. An exemplary connection method can be as follows: a skirt section 2102 is provided on the outer wall of the plug housing 21, and a screw passes through the skirt section 2102 and is threadedly connected to the second side of the first side panel 12111.

[0164] In some examples, such as the attached Figure 10As shown, the soft rubber body 1221 includes a second side wall 12211 and a second top wall 12212 connected to the upper end of the second side wall 12211. The pressing portion 1223 and the light guide hole 1222 are respectively provided on both sides of the second top wall 12212.

[0165] The soft rubber layer 122 is covered on the outside of the hard support layer 121, which includes: the second top wall 12212 of the soft rubber layer 122 covers and adheres to the first top wall 12112 of the hard support layer 121, and the second side wall 12211 of the soft rubber layer 122 covers and adheres to the first side wall 12111 of the hard support layer 121, which is conducive to enhancing the connection strength between the soft rubber layer 122 and the hard support layer 121, thereby ensuring that the soft rubber layer 122 is stably covered on the outside of the hard support layer 121, avoiding unexpected peeling.

[0166] The implementation methods of coating the soft rubber layer 122 on the hard support layer 121 include, but are not limited to: one-piece molding connection, snap connection, key connection, interference sleeve, etc.

[0167] In some examples, the soft rubber layer 122 is formed on the outside of the hard support layer 121 by using a rubber encapsulation process. The rubber encapsulation process is a secondary injection molding process. In this way, the soft rubber layer 122 will be directly molded on the outside of the hard support layer 121, so that the soft rubber layer 122 and the hard support layer 121 are integrally formed, that is, the button 12 is an integrated structure. The button 12 not only has excellent structural stability, but also simplifies the assembly process.

[0168] As mentioned above, a first sealing member 171 is provided between the button 12 and the gun body shell 11. In some examples, the button of the embodiment of the present invention further includes a first sealing member 171, which is formed on the inner wall of the hard support layer support body 1211 by a rubber coating process (combined with Figure 5 It can be seen that it is specifically the inner top of the first top wall 12112 , and the first sealing member 171 is arranged around the light-transmitting portion 1212 .

[0169] It can be seen that the first sealing member 171 is connected to the inner wall of the hard supporting layer 121 of the button 12 and is formed as one piece. In this way, the button 12 abuts against the upper end of the light guide portion 142 through the first sealing member 171, so that the button 12 is in sealed contact with the light guide portion 142. At the same time, this is also conducive to simplifying the assembly process of the button 12 and reducing its assembly difficulty.

[0170] The above describes the various components involved in the gun body 001. The following is a further exemplary description of the composition of the gun head 002:

[0171] In some examples, such as the attached Figure 1 and attached Figure 11As shown, the gun head 002 includes: a plug housing 21, a plurality of pins 22, a front cover 23, a rear cover 24 and a fifth sealing member 25; Figure 12 As shown, a plurality of insertion holes 211 and an installation cavity 212 are provided inside the plug housing 21 , and the installation cavity 212 is communicated with the rear ends of the plurality of insertion holes 211 .

[0172] It can be understood that the jack 211 is arranged in the jack column, and the multiple jacks 211 can each correspond to a jack column, or can share a jack column.

[0173] Multiple pins 22 correspond one-to-one to multiple sockets 211, the pins 22 are located in the corresponding sockets 211, the front cover 23 is against the pins 22 in the installation cavity 212, the fifth seal 25 is against the front cover 23 in the installation cavity 212, and the rear cover 24 is connected to the plug housing 21 and is against the fifth seal 25.

[0174] Cable 004 includes multiple branch lines, the first end of which passes through the back cover 24, the fifth seal 25 and the front cover 23 in sequence and is connected to the corresponding pin 22; the fifth seal 25 has multiple wire holes 250, and the wire holes 250 are interference fit with the corresponding branch lines.

[0175] When the branch line of cable 004 passes through the corresponding wire hole 250 in the fifth seal 25, the branch line and the wire hole 250 form an interference fit, ensuring that the fifth seal 25 is tightly fitted on the outer wall of the branch line, achieving a good sealing effect. By making the plug 22, front cover 23, rear cover 24 and fifth seal 25 abut each other from front to back, the stable assembly of the plug 22 inside the plug housing 21 is ensured. In particular, the fifth seal 25 is provided between the front cover 23 and the rear cover 24. The fifth seal 25 is used to enclose the connection between the branch line of cable 004 and the plug 22 in a confined space, thereby sealing the connection between the plug 22 and the cable 004 and improving the safety of the charging gun.

[0176] The fifth sealing member 25 is made of elastic material such as rubber to make it elastic. The number of wire holes 250 on the fifth sealing member 25 is the same as the number of branch lines of the cable 004. For example, the branch lines of the cable 004 include multiple power branch lines and signal branch lines.

[0177] In some examples, such as the attached Figure 13 As shown, the fifth sealing member 25 includes a gasket portion 251 and a plurality of sleeve portions 252 that are connected to each other. A portion of the wire hole 250 is formed in the gasket portion 251 , and another portion of the wire hole 250 is formed in the sleeve portion 252 .

[0178] As attached Figure 13As shown, the rear cover 24 includes: a first cover body 241 and a plurality of first wire-passing posts 242, the first wire-passing posts 242 are located on the side of the first cover body 241 away from the gasket portion 251; the gasket portion 251 is clamped between the front cover 23 and the first cover body 241, and the sleeve portion 252 is tightly sleeved inside the corresponding first wire-passing posts 242.

[0179] The gasket portion 251 can be tightly clamped between the second cover body 231 of the front cover 23 and the first cover body 241 of the rear cover 24 by means of surface contact, bonding, key connection, etc., and the sleeve portion 252 is tightly sleeved in the first wire column 242 on the rear cover 24. Compared with setting the gasket portion 251 separately for sealing, further additionally designing the sleeve portion 252 can extend the sealing length of the fifth seal 25, thereby improving the sealing effect of the fifth seal 25.

[0180] In some examples, for the first cover body 241 of the rear cover 24 and the second cover body 231 of the front cover 23, the side of both facing the gasket portion 251 is flat, so that the front cover 23, the gasket portion 251, and the rear cover 24 are in contact and abutted in sequence, and the gasket portion 251 is pressed between the front cover 23 and the rear cover 24.

[0181] The wire hole 250 is opened on the fifth sealing member 25 . For the fifth sealing member 25 including a gasket portion 251 and a plurality of sleeve portions 252 , a portion of the wire hole 250 is formed in the gasket portion 251 , and another portion of the wire hole 250 is formed in the sleeve portion 252 .

[0182] In some examples, the wire hole 250 is formed by alternating multiple sealing ring protrusions and multiple sealing grooves. For example, the inner wall of the wire hole 250 is corrugated along its length, and the crest of the inner wall of the wire hole 250 abuts against the outer wall of the corresponding branch line of the cable 004 to form a waterproof sealing ring protrusion. There is a certain gap between the trough of the inner wall of the wire hole 250 and the outer wall of the corresponding branch line of the cable 004 to form a waterproof sealing groove. This not only makes the entire wire hole 250 have a certain deformation ability, which facilitates the assembly of the cable 004, but also ensures that the branch line of the cable 004 is stably wrapped inside the wire hole 250.

[0183] In some examples, such as the attached Figure 13 As shown, the front cover 23 includes: a second cover body 231 and a plurality of second wire-passing posts 232, the second wire-passing posts 232 are located on the side of the second cover body 231 away from the gasket portion 251; the gasket portion 251 is clamped between the second cover body 231 and the first cover body 241; the latch 22 has a cable connecting section 223, the cable connecting section 223 is located in the second wire-passing post 232 and is connected to the branch line.

[0184] The number of the second wire-passing posts 232 is the same as the number of branch lines of the cable 004 . The second wire-passing posts 232 extend toward the direction close to the latch 22 . The second wire-passing posts 232 can abut against the latch 22 , thereby fixing the latch 22 .

[0185] In the embodiment of the present invention, the number of the plugs 22 corresponds to the number of branch lines of the cable 004 . For example, when the cable 004 includes multiple power branch lines and signal branch lines, the number of the plugs 22 is also designed to be the same.

[0186] In some examples, such as the attached Figure 13 and attached Figure 14 As shown, the plug 22 includes: a pin section 221, a sealing section 222 and a cable connection section 223 connected in sequence; Figure 12 It can be seen that the insertion hole 211 includes: a slot section 2111, a first limiting section 2112, a second limiting section 2113 and an assembly section 2114 which are connected in sequence.

[0187] The pin section 221 is located in the slot section 2111 and is radially limited by the first limiting section 2112; the sealing section 222 is sealed in the second limiting section 2113 and is radially limited by the second limiting section 2113, and the front and rear ends of the sealing section 222 along the axial direction are respectively against the first limiting section 2112 and the front cover 23; the cable connection section 223 is located in the assembly section 2114 and is used to connect with the corresponding branch line.

[0188] For example, the pin section 221, the pin section 221, the sealing section 222 and the cable connection section 223 are concentric cylinders with different diameters, wherein the outer diameters of the sealing section 222, the pin section 221 and the cable connection section 223 gradually decrease, so that a limiting step is formed between the sealing section 222 and the pin section 221, and between the sealing section 222 and the cable connection section 223.

[0189] Correspondingly, the slot section 2111, the first limiting section 2112, the second limiting section 2113 and the assembly section 2114 are concentric cylindrical with different diameters, wherein the inner diameter of the slot section 2111 is the largest to facilitate the insertion of the charging device pin, and the inner diameter of the first limiting section 2112 is the smallest.

[0190] The pin segment 221 passes through the first limiting segment 2112 and extends into the slot segment 2111 . The pin segment 221 and the first limiting segment 2112 are clearance-matched. Thus, the first limiting segment 2112 provides radial limitation for the pin segment 221 .

[0191] The sealing sleeve of the sealing section 222 is arranged in the second limiting section 2113 and is radially limited by the second limiting section 2113, that is, the sealing section 222 and the second limiting section 2113 are interference fit, so that the two are in sealed contact. At the same time, the second limiting section 2113 provides radial limitation for the sealing section 222.

[0192] The front end and rear end of the sealing section 222 distributed along the axial direction are respectively abutted against the first limiting section 2112 and the front cover 23. Specifically, the rear end of the sealing section 222 is abutted against the end of the second wire-passing post 232 of the front cover 23 (so that the end of the second wire-passing post 232 of the front cover 23 extends into the interior of the sealing section 222). In this way, the front cover 23 and the plug housing 21 cooperate to limit the pin 22 in the axial direction.

[0193] By defining the structure of the latch 22 and the socket 211 as defined above, and cooperating with the front cover 23, the latch 22 is stably assembled within the socket 211 without undesirable displacement. In some examples, a portion of the cable connecting segment 223 is located within the assembly segment 2114, while another portion extends outside the assembly segment 2114. This facilitates the connection of the cable connecting segment 223 to the corresponding branch line of the cable 004.

[0194] For example, the first end of the branch line of the cable 004 is inserted into the inner cavity of the cable connecting section 223 to make electrical contact therewith, and then the cable connecting section 223 is pinched with a tool to firmly connect it to the end of the cable 004. This method facilitates the connection between the branch line of the cable 004 and the plug 22.

[0195] Furthermore, as attached Figure 13 As shown, there is a sixth seal 26 between the sealing section 222 of the pin 22 and the second limiting section 2113 of the socket 211. The sixth seal 26 is used to seal the gap between the pin 22 and the socket 211 to prevent water, dust and other impurities from entering the connection between the pin 22 and the cable 004 from the front end of the socket 211.

[0196] In some examples, such as the attached Figure 14 As shown, the sealing section 222 of the latch 22 is provided with an annular sealing groove, and the sixth sealing member 26 is sleeved within the annular sealing groove. For example, the sixth sealing member 26 is an O-ring, and the annular sealing groove is an O-groove. Sleeving the sixth sealing member 26 onto the latch 22 forms an integral structure with the latch 22, which simplifies the assembly process of the latch 22.

[0197] It can be seen that for the cable connection section 223 of the pin 22 (i.e., the connection between the pin 22 and the corresponding branch line of the cable 004), a fifth seal 25 is arranged on its rear side, and a sixth seal 26 is arranged on its front side. The fifth seal 25 and the sixth seal 26 work together to seal the front and rear channels between the cable connection section 223 of the pin 22 and the outside world, ensuring that the connection between the pin 22 and the corresponding branch line of the cable 004 will never be disturbed by impurities such as water and dust, thereby improving the safety of the charging gun.

[0198] In addition, the rear cover 24 is connected to the plug housing 21 and abuts against the fifth sealing member 25 . The connection methods between the rear cover 24 and the plug housing 21 include but are not limited to: snap connection, riveting, screw connection, bonding, etc.

[0199] Taking screw connection as an example, multiple first screw columns 213 can be set inside the plug housing 21, so that the screws pass through the back cover 24, the fifth seal 25 and the front cover 23 in sequence, and then are threadedly connected with the first screw columns 213, thereby simultaneously achieving a stable connection between the back cover 24, the fifth seal 25 and the front cover 23 and the plug housing 21.

[0200] Furthermore, in order to make the above connection more stable, the rear cover 24 may also be in contact with the rear end surface of the plug housing 21 at the same time.

[0201] After the plug pin 22 is assembled to the plug housing 21 , the two cooperate to form a plug, which can be inserted into the power receiving port of the powered device to achieve electrical connection between the charging gun and the powered device.

[0202] In some examples, such as the attached Figure 12 As shown, the plug housing 21 includes: a plug section 2101, a skirt section 2102 and a gun body connecting section 2103 connected in sequence, wherein the plug section 2101 is designed in the shape of a plug, which can be inserted into the power receiving port of the power receiving device.

[0203] The skirt section 2102 is sleeved on the outside of the plug section 2101 and the gun body connecting section 2103 and is in the shape of a raised ear plate. The skirt section 2102 is used to be connected to the button 12 via screws.

[0204] The gun body connecting section 2103 is used to connect with the front end of the gun body part 001. For example, the gun body connecting section 2103 is inserted into the front end of the gun body, that is, the two are connected by friction or further key.

[0205] In order to improve the connection effect between the gun head portion 002 and the gun body portion 001 , further, a screw can be used to penetrate the side wall of the front port of the gun body shell 11 and then be threadedly connected to the side wall of the gun body connecting section 2103 .

[0206] In some examples, such as the attached Figure 1-3 As shown, the gun head 002 further includes: a front end cover 27 , which is detachably connected to the plug housing 21 and is used to seal the front port of the plug housing 21 .

[0207] For example, the front cover 27 can be fitted over the plug section 2101 of the plug housing 21 and secured by friction between the two. This allows the front cover 27 to block the front port of the plug housing 21, providing protection when the charging gun is not in operation. When the charging gun is charging, the front cover 27 can be removed.

[0208] In some examples, an anti-lost rope 28 is also provided between the front end cover 27 and the plug housing 21. In this way, after the front end cover 27 is removed from the front port of the plug housing 21, the front end cover 27 still remains connected to the plug housing 21 to prevent the front end cover 27 from being lost.

[0209] In some examples, such as the attached Figure 1 As shown, the charging gun provided by the embodiment of the present invention further includes a gun tail portion 003 , which is connected to the rear end of the gun body portion 001 , and is configured to fix the cable 004 .

[0210] It can be understood that the cable 004 involved in the embodiment of the present invention can be a comprehensive cable composed of multiple branch lines. For example, multiple power branch lines and signal branch lines are sheathed in an insulating sheath. The cable 004 is introduced from the gun tail 003 to the gun head 002. In the gun head 002, each branch line is connected to the corresponding pin 22 respectively, and the gun tail 003 is used to fix the cable 004.

[0211] In some examples, such as the attached Figure 15 , Attachment Figure 16 and attached Figure 17 As shown, the gun tail 003 includes: a clamping member 31, the clamping member 31 has a first clamping cavity 301 with an adjustable inner diameter, and the first clamping cavity 301 is used to fix and clamp the cable; a limiting bracket 32, the limiting bracket 32 ​​is used to support the clamping member 31 and limit the clamping member 31; and a pressure cover assembly 33, the pressure cover assembly 33 is used to fix the limiting bracket 32 ​​to the rear end of the gun body 001.

[0212] The rear end portion 003 of the charging gun according to an embodiment of the present invention clamps and secures the cable 004 via a clamp 31. The inner diameter of the first clamping cavity 301 of the clamp 31 is adjustable, enabling the clamp 31 to achieve a good clamping effect for cables 004 of varying diameters. After the clamp 31 secures the cable 004, the clamp 31 is supported and positioned by a limiting bracket 32, securing the clamp 31 within the limiting bracket 32 ​​and preventing undesirable displacement. The limiting bracket 32 ​​is compressed and secured to the rear end of the gun body 001 using a pressure cap assembly 33, ultimately securing the cable 004 within the charging gun.

[0213] The structure of the clamping member 31 can be designed in various ways, and all clamping members 31 with adjustable tightness are applicable to the embodiments of the present invention.

[0214] In some examples, such as the attached Figure 17 As shown, the clamping member 31 involved in the embodiment of the present invention includes: a first clamp 3101, a second clamp 3102 and two locking screws 3103; the first clamp 3101 includes: a first arc-shaped clamping portion 3111, and two first lugs 3112 located at opposite ends of the first arc-shaped clamping portion 3111; the second clamp 3102 includes: a second arc-shaped clamping portion 3121, and two second lugs 3122 located at opposite ends of the second arc-shaped clamping portion 3121.

[0215] The first arc-shaped clamping portion 3111 and the second arc-shaped clamping portion 3121 are arranged opposite to each other and cooperate to form the first clamping cavity 301 ; the first lug 3112 and the second lug 3122 located on the same side are connected by corresponding locking screws 3103 .

[0216] It can be understood that after the first clamp 3101 and the second clamp 3102 are adapted and connected, the diameter of the first clamping cavity 301 between the first arc-shaped clamping portion 3111 and the second arc-shaped clamping portion 3121 is also adjusted accordingly according to the diameter of the cable 004, ensuring that the first arc-shaped clamping portion 3111 and the second arc-shaped clamping portion 3121 tightly hold the cable 004.

[0217] The spacing between the first lug 3112 and the second lug 3122 located on the same side is also adjusted accordingly according to the diameter of the first clamping cavity 301. Since the first lug 3112 and the second lug 3122 are connected by corresponding locking screws 3103, and since the connection is made by a threaded connection, by adjusting the tightening degree of the locking screw 3103 (i.e., the screw-in stroke), the first lug 3112 and the second lug 3122 at different spacings can be effectively fastened and connected.

[0218] It can be seen that the first clamp 3101 and the second clamp 3102 are relatively independent and connected by the locking screw 3103. In this way, by adjusting the tightening degree of the locking screw 3103, the inner diameter of the first clamping cavity 301 can be adjusted, so that a good clamping effect can be achieved for cables 004 of different diameters.

[0219] Both the first clamp 3101 and the second clamp 3102 are provided with lugs, which are not only used to connect the two first clamps 3101 and the second clamp 3102, but also because they are protruding on both sides of the corresponding arc-shaped clamping parts, the lugs can also prevent the clamping member 31 from rotating when placed in the limit bracket.

[0220] In some examples, the first arc-shaped clamping portion 3111 and the second arc-shaped clamping portion 3121 may both be arc-shaped, such as a semicircular arc or a semicircular arc.

[0221] In some examples, for the first lug 3112 and the second lug 3122 located on the same side, the screw through holes of both can be designed as internal threaded holes, or only the one away from the head of the locking screw 3103 can be designed as an internal threaded hole.

[0222] In other examples, for the first lug 3112 and the second lug 3122 located on the same side, the screw through holes of both can be designed as non-threaded holes, so that a nut with an internal threaded hole can be connected to the lug away from the head of the locking screw 3103.

[0223] As a typical example, the attached Figure 17 As shown, at least one of the first lug 3112 and the second lug 3122 on the same side is coaxially connected to a nut column 3113, which is used to connect to the locking screw 3103. For example, the lug away from the head of the locking screw 3103 is coaxially connected to the nut column 3113.

[0224] In this example, the screw through holes on the first lug 3112 and the second lug 3122 may be internal threaded holes or non-threaded holes.

[0225] By setting the nut column 3113, not only the connection stability between it and the locking screw 3103 can be improved, but also the locking screw 3103 can be more adaptable to the first clamping cavity 301 with different inner diameters, so that excellent locking effect can be obtained for clamps with different clamping diameters.

[0226] In some examples, such as the attached Figure 17As shown, the first clamp 3101 also includes: a first wire pressing structure 3131, the first wire pressing structure 3131 is connected to the first arc-shaped clamping portion 3111; the second clamp 3102 also includes: a second wire pressing structure 3132, the second wire pressing structure 3132 is connected to the second arc-shaped clamping portion 3121; the first wire pressing structure 3131 and the second wire pressing structure 3132 are both used to contact the surface of the cable.

[0227] By adding a wire pressing structure to the clamp to contact the surface of the cable, the tightening and clamping effect of the clamping member 31 on the cable 004 can be improved.

[0228] In some examples, such as the attached Figure 17 As shown, the first wire pressing structure 3131 and the second wire pressing structure 3132 both include a plurality of claws 3130 arranged at intervals; the plurality of claws 3130 of the first wire pressing structure 3131 and the plurality of claws 3130 of the second wire pressing structure 3132 cooperate to form a second clamping cavity 302, the second clamping cavity 302 is coaxially connected to the first clamping cavity 301, and the inner diameter of the second clamping cavity 302 is smaller than the inner diameter of the first clamping cavity 301.

[0229] A plurality of claws 3130 are connected to at least one of the two arcuate ends of the corresponding arcuate clamping portion. For example, two opposite arcuate ends of the arcuate clamping portion are each connected to a plurality of claws 3130. The claws 3130 are used to grip the surface of the cable 004, thereby increasing the contact friction between the first clamp 3101 and the second clamp 3102 and the cable 004.

[0230] For example, the first end of the clamping claw 3130 is connected to the arcuate end of the corresponding arcuate clamping portion, and the second end of the clamping claw 3130 is suspended and extends toward the cable 004. The above design of the clamping claw 3130 not only makes the clamping claw 3130 elastic to prevent scratching the cable 004, but also ensures that the clamping inner diameter of the second clamping cavity 302 is adjustable, ensuring that the clamping member 31 is more adaptable to cables 004 of different diameters and achieving a better clamping effect for cables 004 of various diameters.

[0231] Of course, the above-mentioned wire pressing structure can also be a protrusion arranged on the inner wall of the arc-shaped clamping part. The protrusion can be arranged in a circular arc shape around the inner wall of the arc-shaped clamping part in multiple circles, or it can be arranged in a convex point shape on the inner wall of the arc-shaped clamping part. All of the above can achieve a good clamping effect.

[0232] The limiting bracket 32 ​​is used to support and limit the clamping member 31. In some examples, such as the attached Figure 18 As shown, the limiting bracket 32 ​​includes: a clamp accommodating cavity 321, and two limiting cavities 322 located on opposite sides of the clamp accommodating cavity 321. Figure 19As can be seen, the clamp housing cavity 321 is used to accommodate the first arc-shaped clamping portion 3111 and the second arc-shaped clamping portion 3121, while the limiting cavity 322 is used to accommodate the first lug 3112 and the second lug 3122 and limit their positions. The limiting includes radial limiting along the radial direction of the cable and axial limiting along the axial direction of the cable.

[0233] For example, the clamp accommodating cavity 321 is a circular cavity, and the limiting cavity 322 is a rectangular cavity with an opening. By allowing the first clamp 3101 and the second clamp 3102 to enter the limiting cavity 322 through the above-mentioned openings, and using the limiting cavity 322 to limit the lug, the clamp can be effectively prevented from rotating and moving axially in the limiting bracket 32, thereby realizing the limitation of the clamping member 31 in the limiting bracket 32.

[0234] In some examples, the limiting bracket 32 ​​is formed by stamping and bending both sides of the annular plate, wherein the inner cavity of the annular plate serves as the clamp accommodating cavity 321 and the bending portion of the annular plate forms the limiting cavity 322 .

[0235] By stamping and bending the annular sheet material, a one-piece limit bracket 32 ​​is formed. This allows the limit cavity 322 to not only prevent the clamping member 31 from rotating within the limit cavity 322 but also prevent the clamping member 31 from moving in a first axial direction away from the gland assembly 33, thus limiting the clamping member 31 in multiple directions. Furthermore, because the gland assembly 33 presses the limit bracket 32 ​​tightly against the charging gun's housing 11, it also prevents movement of the limit bracket 32 ​​in a second axial direction.

[0236] For example, the annular plate is made of zinc alloy, which makes it easy to form the limiting bracket 32 ​​and helps the limiting bracket 32 ​​maintain high strength.

[0237] In some examples, the length of the locking screw 3103 is greater than the length of the first lug 3112 and the second lug 3122 located on the same side and the optional nut column 3113 in the same direction, that is, after the locking screw 3103 is locked, its head and tail both extend to the outside of the lug or nut column 3113.

[0238] In some examples, the length of the locking screw 3103 is the same as the length of the limiting cavity 322, so that both ends of the locking screw 3103 abut against corresponding side walls of the limiting cavity 322. The head and tail of the locking screw 3103 abut against corresponding side walls of the limiting cavity 322, respectively. Thus, after the clamp is tightened, the locking screw 3103 fits snugly into the limiting cavity 322, ensuring that the clamp 31 can be secured by the limiting bracket 32 ​​even when securing cables of different diameters, effectively preventing the clamp 31 from rotating within the limiting bracket 32.

[0239] The pressure cover assembly 33 is used to fix the limit bracket 32 ​​in the gun body shell 11 of the charging gun. In some examples, such as the attached Figure 15 As shown, the rear end of the gun body shell 11 of the charging gun is provided with a second accommodating cavity 112, and the interior of the second accommodating cavity 112 has a limiting step 115. The pressure cover assembly 33 includes: a rear end cover 331, the rear end cover 331 is connected to the gun body shell 11 of the charging gun, and the limiting bracket 32 ​​is located in the second accommodating cavity 112, and the rear end cover 331, the limiting bracket 32, and the limiting step 115 are sequentially abutted (see Figure 15 ,because Figure 15 A similar implementation is illustrated), in this way, the limiting bracket 32 ​​is blocked by the rear end cover 331 and the limiting step 115, thereby achieving fixation inside the gun body shell 11 of the charging gun.

[0240] The rear end cap 331 can be connected to the charging gun's gun body 11 in a variety of ways, such as screws, clamps, or rivets. For example, a plurality of second screw posts 114 are disposed within the second accommodating cavity 112. The second screw posts 114, the position-limiting bracket 32, and the rear end cap 331 are sequentially abutted and connected via screws. The screws penetrate screw holes in the rear end cap 331 and the position-limiting bracket 32 ​​and threadably engage with the second screw posts 114. This secures the position-limiting bracket 32 ​​and the rear end cap 331 to the charging gun's gun body 11, thereby securing the cable 004 within the charging gun's gun body 11.

[0241] In other examples, such as the Figure 15 As shown, the gun body shell 11 of the charging gun is provided with a second accommodating cavity 112, and a limiting step 115 is provided inside the second accommodating cavity 112. Figure 16 It can be seen that the gland assembly 33 includes: a rear end cover 331 and a wire protection sleeve 332 . The wire protection sleeve 332 includes an annular gasket 3321 and a protection sleeve 3322 connected to one side of the annular gasket 3321 .

[0242] As attached Figure 16 As shown, the rear end cover 331 is connected to the gun body shell 11 of the charging gun, the limiting bracket 32 ​​and the annular gasket 3321 are both located in the second accommodating cavity 112, and the rear end cover 331, the annular gasket 3321, the limiting bracket 32, and the limiting step 115 are abutted in sequence; the sheath 3322 passes through the rear end cover 331 and extends to the outside of the gun body shell 11 of the charging gun.

[0243] In this example, the rear end cover 331 is connected to the gun body shell 11 of the charging gun in the same way as the above example. The screws pass through the screw holes on the rear end cover 331, the annular gasket 3321 and the limiting bracket 32 ​​in sequence and are threadedly connected to the second screw column 114. In this way, the limiting bracket 32 ​​is clamped between the second screw column 114 and the annular gasket 3321 to achieve fixation inside the second accommodating cavity 112.

[0244] This example specifically adds a wire protection cover 332, which passes through the rear end cover 331 and extends to the outside of the gun body shell 11 of the charging gun. In this way, the sheath 3322 protects the cable 004 located outside the gun body shell 11. The length of the sheath 3322 can be adaptively designed according to the length of the cable 004 to be protected.

[0245] On the other hand, an embodiment of the present invention further provides a charging system, which includes any of the above-mentioned charging guns.

[0246] The charging system involved in the embodiment of the present invention has all the same advantages as the charging gun, which will not be described in detail here.
