[0038] See also Figures 1 to 4Now, a charging gun provided by the utility model is described. A charging gun includes a gun body 100 and an alarm mechanism.

[0039] A charging connector 110 is provided at one end of the gun body 100, and an outlet terminal plate 120 is provided at the other end of the gun body 100. An installation chamber 130 is formed inside the gun body 100, and a cable 300 is provided in the installation chamber 130. One end of the cable 300 is connected to the charging connector 110, and the other end of the cable 300 passes through the outlet terminal plate 120 and is connected to the vehicle battery; the alarm mechanism includes a movable plate 140, a touch switch 210, a controller 220 and a warning module. The movable plate 140 is located in the installation chamber 130 and is connected to the cable 300. The touch switch 210 is installed on the inner wall of the installation chamber 130 and is located between the movable plate 140 and the outlet terminal plate 120. The movable plate 140 is pulled outward with the cable 300 to touch the touch switch 210. The controller 220 is arranged in the installation chamber 130 and is electrically connected to the touch switch 210 and the warning module respectively. The warning module triggers an alarm signal by receiving a control signal from the controller 220.

[0040] The utility model provides a charging gun. Compared with the prior art, a charging connector 110 is provided at one end of a gun body 100, and an outlet terminal plate 120 is provided at the other end. A cable 300 is located in an installation chamber 130 of the gun body 100. One end of the cable 300 is connected to the charging connector 110, and the other end passes through the outlet terminal plate 120 and is connected to a vehicle battery. The charging connector 110 is connected to an external power supply, and the vehicle battery is charged through the cable 300. When using a charging gun provided by the utility model for charging, if the charging gun is far away from the charging pile, the user will pull the charging gun, and the cable 300 will drive the movable plate 140 in the installation chamber 130 to move toward the side of the outlet end plate 120 until the movable plate 140 contacts the above-mentioned touch switch 210. The touch switch 210 sends a sensing signal to the controller 220. After receiving the sensing signal, the sensing signal generates a corresponding control signal and sends it to the warning module. After receiving the control signal, the warning module sends an alarm signal to remind the user that the tension between the charging gun and the cable 300 is too large. The user stops pulling the charging gun, thereby avoiding damage to the charging gun or poor contact during charging, which may cause charging interruption or fire.

[0041] A charging gun is a device used to charge an electric vehicle, usually connected to a charging pile or charging station. It is the interface between the electric vehicle and the power supply network, used to transfer electrical energy to charge the battery of the electric vehicle.

[0042] See also Figure 1The gun body 100 is made of injection molding technology. The charging connector 110 is inserted into the upper port of the gun body 100. A plurality of positioning bolts are arranged on the periphery of the upper port of the gun body 100. The plurality of positioning bolts radially penetrate the outer wall of the gun body 100 and abut against the reserved groove on the periphery of the charging connector 110, so as to install the charging connector 110 on the upper port of the gun body 100. The outlet end plate 120 is buckled on the lower port of the gun body 100. The end surface of the end plate is provided with a plurality of through holes in the circumferential direction. The connecting bolts penetrate the through holes and are threadedly connected to the end surface of the lower port of the cavity. In order to ensure that the cable 300 in the installation chamber 130 can drive the movable plate 140 to move to the side of the outlet end plate 120 under the action of the external force of the user, the cable 300 between the charging connector 110 and the movable plate 140 is in a non-tightened state, which can be in a bent or winding state.

[0043] See also Figure 1 and Figure 4 The warning module includes an oscillating unit 230 and a warning light 240 . The oscillating unit 230 is disposed on the inner wall of the mounting chamber 130 , and the warning light 240 is embedded on the outer wall of the gun body 100 . The oscillating unit 230 and the warning light 240 are connected in parallel to the controller 220 .

[0044] After the oscillation unit 230 receives the control signal from the controller 220, the oscillation unit 230 generates a vibration signal, which is transmitted to the user's holding hand through the gun body 100, reminding the user that the tension between the charging gun and the cable 300 is too large. Similarly, after the warning light 240 receives the control signal from the controller 220, the warning light 240 generates a light signal, reminding the user that the tension between the charging gun and the cable 300 is too large. The above-mentioned vibration signal and light signal can be activated at the same time to remind the user together, and the warning effect is better.

[0045] See also Figure 3 The oscillation unit 230 includes a fixing frame 231 , a driving motor 232 and an eccentric cam 233 .

[0046] The fixing frame 231 is arranged on the inner wall of the installation chamber 130, the driving motor 232 is installed on the fixing frame 231 and electrically connected to the controller 220, the eccentric cam 233 is installed on the driving end of the driving motor 232, and the driving motor 232 drives the eccentric cam 233 to rotate to generate a vibration signal. Among them, the fixing frame 231 has two free ends, and the two free ends are respectively installed on the inner wall of the installation chamber 130 by screws. The fixing frame 231 and the inner wall of the installation chamber 130 form an assembly space, and the driving motor 232 is pressed into the assembly space to maintain stability. The driving end of the driving motor 232 is connected to the fixed connection hole opened in the center of the eccentric cam 233. The eccentric cam 233 has a small cam end 2331 and a large cam end 2332 on both sides, and the diameter of the large cam end 2332 is twice the diameter of the small cam end 2331. The driving motor 232 drives the eccentric cam 233 to rotate, so that the small cam end 2331 and the large cam end 2332 of the eccentric cam 233 intermittently collide with the inner wall of the installation chamber 130, so that the gun body 100 generates a vibration signal to be transmitted to the user's holding hand.

[0047] See also Figure 1 and Figure 4 The charging gun also includes a built-in battery 250 and a charging interface 260. The built-in battery 250 is arranged on the inner wall of the installation chamber 130 and is electrically connected to the controller 220. The charging interface 260 is arranged on the side wall of the gun body 100 and is electrically connected to the built-in battery 250. The charging interface 260 charges the built-in battery 250 through an external power source. The charging interface 260 is a USB interface. The built-in battery 250 is a storage battery. The built-in battery 250 is charged by connecting an external power source through the charging interface 260. The built-in battery 250 also provides power for the controller 220, the drive motor 232 and the warning light 240.

[0048] See also Figure 2 The outer end surface of the outlet end plate 120 is provided with a conical elastic sleeve 121. The outlet end plate 120 and the conical elastic sleeve are made of an integrally formed rubber material. The outlet end plate 120 and the conical elastic sleeve are coaxially provided with a through hole for the cable 300 to pass through. The outer diameter of the conical elastic sleeve 121 decreases from the direction close to the outlet end plate 120 to the direction away from the outlet end plate 120. The outer end of the conical elastic sleeve is more prone to deformation. When the user stores the cable 300, the cable 300 can be bent and wound. At this time, the conical elastic sleeve is bent and deformed synchronously with the cable 300 to avoid sharp creases in the cable 300, which may cause damage to the cable 300 at the crease.

[0049] In addition, a plurality of annular grooves 1211 are circumferentially arranged on the outer wall of the conical elastic sleeve 121. The plurality of annular grooves 1211 are axially spaced apart from each other and enable the conical elastic sleeve 121 to deform laterally more easily, which is more conducive to the bending and winding of the cable 300.

[0050] The inner end surface of the outlet end plate 120 is provided with a guide sleeve 122, which is integrally formed with the outlet end plate 120. An annular guide groove 1221 is provided at the end of the guide sleeve 122. A sliding sleeve 141 is provided on the side of the movable plate 140 close to the outlet end plate 120, and the sliding sleeve 141 is axially slidably arranged in the annular guide groove 1221. The sliding fit between the sliding sleeve 141 and the annular guide groove 1221 provides guidance for the movement of the movable plate 140, so that it moves along the axial direction of the installation chamber 130, ensuring that it can contact the above-mentioned touch switch 210 in the state of being pulled by the cable 300. The outer diameter of the guide sleeve 122 is smaller than the outer diameter of the movable plate 140. When the movable plate 140 is driven by the pulled cable 300 to move in the direction where the end plate appears, the portion of the movable plate 140 protruding from the edge of the guide sleeve 122 contacts the above-mentioned touch switch 210, so that the touch switch 210 generates an induction signal.

[0051] Optionally, a positioning protrusion 142 is provided in the middle of one side of the movable plate 140 close to the outlet terminal plate 120. The positioning protrusion 142 is located inside the sliding sleeve 141. The positioning protrusion 142 is a conical platform. A compression spring 150 is provided between the movable plate 140 and the outlet terminal plate 120. The compression spring 150 is sleeved on the outer periphery of the positioning protrusion 142. When the compression spring 150 is further compressed, the conical platform can prevent the compression spring 150 from radial deformation, ensuring that it has resilience. When the user pulls the charging gun excessively, the movable plate 140 will further compress the above-mentioned compression spring 150. When the user stops pulling the charging gun, the compression spring 150 will release its own elastic force to drive the movable plate 140 to reset.

[0052] In one embodiment, see Figure 2 The inner wall of the installation chamber 130 is provided with a limit plate 160, which is located on the side of the movable plate 140 away from the outlet terminal plate 120. The limit plate 160 extends along the radial direction of the installation chamber 130, and is used to limit the distance that the movable plate 140 moves into the installation chamber 130. Specifically, the limit plate 160 is located on the opposite side of the touch switch 210. When the user stops pulling the cable 300, the compression spring 150 drives the movable plate 140 to move to the side away from the outlet terminal plate 120 until the movable plate 140 contacts the limit plate 160, and the movable plate 140 stops moving. The design of the limit plate 160 can limit the distance that the movable plate 140 moves into the installation chamber 130, and prevent the movable plate 140 from driving the sliding sleeve 141 to disengage from the annular guide groove 1221.

[0053] Based on the same inventive concept, the utility model also provides an electric vehicle, which uses the above-mentioned charging gun. When the electric vehicle is charging, the user will pull the charging gun, and the cable 300 will drive the movable plate 140 in the installation chamber 130 to move toward the side of the outlet end plate 120 until the movable plate 140 contacts the above-mentioned touch switch 210. The touch switch 210 sends a sensing signal to the controller 220. After receiving the sensing signal, the sensing signal generates a corresponding control signal and sends it to the warning module. After receiving the control signal, the warning module sends an alarm signal to remind the user that the tension between the charging gun and the cable 300 is too large. The user stops pulling the charging gun, thereby avoiding damage to the charging gun or poor contact during charging, which may cause charging interruption or fire.

[0054] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
