[0002] Currently, charging guns have a housing assembly, which includes a housing base and a handle. The charging terminal is located inside the housing base. The housing assembly is hinged to a locking arm, with a hook at the front end for engaging the charging socket and a raised button at the rear end. Pressing the raised button disengages the hook, allowing the charging gun to be removed from the charging socket. To prevent the charging gun from being pulled out while energized, DC charging guns are equipped with electronic lock components, such as the "Integrated Electronic Lock" in Chinese Utility Model Patent Publication No. CN214659437U and the "Charging Terminal Module and Charging Gun" in Chinese Utility Model Patent Publication No. CN215645341U. The electronic lock component can prevent the raised button from being pressed. The electronic lock component is located inside the handle. The raised button extends upward through the housing assembly for easy user operation. However, rainwater can seep into the housing assembly through the gap between the raised button and the housing assembly, easily causing the electronic lock component to become submerged in water and malfunction. Therefore, an effective drainage structure is necessary. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a drainage structure for a charging gun, which is beneficial to improving the drainage effect of the charging gun.

[0025] The present invention will now be further described with reference to the accompanying drawings.

[0026] The charging gun drainage structure of this utility model, such as Figures 1 to 6 As shown, the device includes a gun housing assembly 1, which has a locking arm 2. Specifically, the gun housing assembly 1 includes a gun housing base 11 and a handle portion 12. The charging terminal of the charging gun is located inside the gun housing base 11. Figure 3 As shown, the gun housing 11 and the handle portion 12 are sealed and isolated. The handle portion 12 is integrally connected to the outer wall of the gun housing 11. The front end of the handle portion 12 is provided with a hinge shaft 23. The locking arm 2 is connected to the handle portion 12 through the hinge shaft 23, so that the locking arm 2 can swing around the hinge shaft 23. The front end of the locking arm 2 is formed with a locking hook 21 for engaging the charging socket. Figure 2 and Figure 7 As shown, a protruding button 22 is formed on the upper side of the locking arm 2, and a drainage groove 221 is formed on the locking arm 2. The drainage groove 221 is wrapped around the lower end of the protruding button 22, and the drainage groove 221 has a drainage outlet 2211. By setting the drainage groove 221, rainwater flowing down the outer wall of the protruding button 22 can fall into the drainage groove 221. Through the guiding effect of the drainage groove 221, the water is discharged in an orderly manner through the drainage outlet 2211 to the outside of the locking arm 2, which helps to speed up drainage and also prevents rainwater from flowing directly down the outer wall of the protruding button 22 into the gun housing assembly 1.

[0027] Furthermore, such as Figure 2 , Figure 3 and Figure 7As shown, a convex button 22 is formed at the rear end of the locking arm 2. The rear end of the locking arm 2 is bent downwards, and the rear end of the locking arm 2 forms an obtuse angle of about 163° to 165° with the body of the locking arm 2. The body of the locking arm 2 is roughly horizontal in its free state. The drainage outlet 2211 is located at the rear end of the locking arm 2, that is, the drainage outlet 2211 extends backwards through the locking arm 2. Since the rear end of the locking arm 2 is bent downwards, the rear end of the drainage ditch 221 is bent downwards, which facilitates the rapid discharge of water in the drainage ditch 221 through the drainage outlet 2211 by gravity.

[0028] Furthermore, such as Figure 7 As shown, there are two drainage outlets 2211, which are distributed on the left and right sides of the convex button 22. This can shorten the distance that the water flows to the drainage outlets 2211, thus speeding up the discharge of water from the drainage ditch 221. For example, the two drainage outlets 2211 can be separated, making the drainage ditch 221 shaped like the letter "C". That is to say, the drainage ditch 221 is an open-loop structure. Since the rear outer wall of the convex button 22 is close to the rear end of the latch arm 2, the rainwater flowing down along the rear outer wall of the convex button 22 falls to the rear end of the latch arm 2. Since the rear end of the latch arm 2 is bent downward, the rainwater can easily be discharged backward and downward outside the latch arm 2. Since the drainage ditch 221 is an open-loop structure, the total length of the drainage ditch 221 is shortened, which can reduce the difficulty of manufacturing the drainage ditch 221. Since the drainage outlet 2211 extends backward through the latch arm 2, the convex button 22 is actually still within the area enclosed by the drainage ditch 221. Of course, in some embodiments, the drainage ditch 221 can also be set to completely surround the convex button 22.

[0029] Furthermore, such as Figure 2 and Figure 5 As shown, the gun casing assembly 1 includes a handle portion 12, which has a mounting groove 121 extending upward through the handle portion 12, meaning the mounting groove 121 is open upwards. An electronic lock assembly 5 is disposed on the upper side of the bottom of the mounting groove 121; specifically, the mounting groove 121 accommodates the electronic lock assembly 5. A support post is formed at the bottom of the mounting groove 121, and the electronic lock assembly 5 is mounted on the support post using corresponding screws, leaving a gap between the electronic lock assembly 5 and the bottom of the mounting groove 121. Figure 3 and Figure 4 As shown, the rear part of the locking arm 2 is located inside the upper end of the mounting groove 121, so that the drain outlet 2211 is located inside the upper rear part of the mounting groove 121. The rear end of the handle part 12 forms a handle tail opening 122, as shown. Figure 5 and Figure 6 As shown, a rear drainage hole 1211 is formed at the lower rear end of the mounting groove 121, as... Figure 3As shown, the rear drain hole 1211 connects to the handle tail opening 122. (As indicated...) Figure 3 As shown, the water discharged from the drainage ditch outlet 2211 then falls to the bottom of the mounting groove 121. Since the lower rear end of the mounting groove 121 has a rear drainage hole 1211, the water can reach the rear drainage hole 1211 through a shorter distance. Then the water is discharged through the handle tail opening 122, which is conducive to rapid and effective drainage and avoids water accumulation in the mounting groove 121, which would cause the electronic lock component 5 to be immersed in the water. That is to say, the drainage structure of this utility model can prevent water accumulation in the charging gun.

[0030] Furthermore, such as Figure 3 As shown, a drainage channel 120 with a front-high and rear-low orientation is formed in the rear part of the handle part 12. The rear drainage hole 1211 is connected to the handle tail opening 122 through the drainage channel 120. That is to say, the rear part of the handle part 12 is tubular (it can be a square tube). The drainage channel 120 is equivalent to the cavity of the rear part of the handle part 12. Thus, the structure is simple to connect the rear drainage hole 1211 to the handle tail opening 122. Moreover, the structure of the drainage channel 120 is short. Since the drainage channel 120 is inclined with a front-high and rear-low orientation, it is beneficial for the water flowing from the rear drainage hole 1211 into the drainage channel 120 to quickly flow to the handle tail opening 122 and be discharged to the outside through gravity.

[0031] Furthermore, such as Figure 3 As shown, a flow guide rounded corner 1221 is formed on the lower inner side of the handle tail opening 122, making the lower inner part of the handle tail opening 122 gradually steeper, so that the water flowing to the lower inner side of the handle tail opening 122 is more easily discharged.

[0032] Furthermore, such as Figure 3 and Figure 6 As shown, a lower drainage groove 1212 is formed at the bottom of the mounting groove 121. The lower drainage groove 1212 extends downward through the handle portion 12, so that water that cannot be drained through the rear drainage hole 1211 can also be drained to the outside of the gun housing assembly 1 through the lower drainage groove 1212, further preventing water accumulation inside the gun housing assembly 1.

[0033] Furthermore, such as Figure 6 As shown, ribs 1214 are formed on the left and right sides of the rear drainage hole 1211, thereby increasing the structural strength of the edge of the rear drainage hole 1211 and preventing the structural strength of the gun casing assembly 1 from being significantly reduced due to the formation of the rear drainage hole 1211.

[0034] Furthermore, such as Figures 1 to 3 As shown, the gun case assembly 1 includes a decorative cover 13, which is disposed on the mounting groove 121. Specifically, a hinge shaft 23 is adapted to pass through the front end of the decorative cover 13, and the rear end of the decorative cover 13 is fixedly connected to the handle portion 12 by corresponding screws. Figure 2 and Figure 8 As shown, the mounting groove 121 has a raised edge 1213 on the groove opening, which is located inside the decorative cover 13. The rear part of the locking arm 2 is located on the lower side of the decorative cover 13, and the rear part of the decorative cover 13 has a clearance hole 1301. Figure 1 and Figure 3 As shown, the convex button 22 passes through the clearance hole 1301, and the front end of the latch arm 2 extends forward beyond the decorative cover 13, as shown. Figure 7 As shown, by setting the upper protrusion 1213 of the slot on the inner side of the decorative cover 13, the rainwater flowing down from the outer wall of the decorative cover 13 will be blocked by the upper protrusion 1213, making it difficult for the rainwater to seep into the mounting groove 121. A small amount of rainwater that enters the mounting groove 121 through the gap between the front end of the locking arm 2 and the front end of the decorative cover 13 will also be discharged to the outside of the gun housing assembly 1 through the lower drainage groove 1212 or the rear drainage hole 1211.

[0035] Furthermore, such as Figure 2 , Figure 3 and Figure 8 As shown, the convex key 22 is covered with a keycap 3. The lower end of the keycap 3 is located within a clearance hole 1301, which is situated within the corresponding range of the drainage ditch 221. That is, the gap between the outer wall of the lower end of the keycap 3 and the inner wall of the clearance hole 1301 is within the receiving range of the drainage ditch 221, allowing water seeping down from this gap to be caught by the drainage ditch 221. The keycap 3 serves a decorative function and can be connected to the convex key 22 using corresponding screws.

[0036] When the keycap 3 is pressed, the keycap 3 and the decorative cover 13 will move relative to each other. If a sealing ring is set between the keycap 3 and the clearance hole 1301, the sealing ring will be easily worn. Moreover, the charging gun will be used outdoors, which will easily lead to the aging of the sealing ring. Therefore, this utility model adopts a drainage ditch 221 to guide water seepage, and combines it with drainage structures such as the rear drainage hole 1211, the lower drainage groove 1212 and the drainage channel 120. This is conducive to the charging gun draining water quickly and effectively, which is conducive to improving the drainage effect of the charging gun. This avoids the use of the aforementioned sealing ring, thereby making the anti-water accumulation effect inside the charging gun last longer and more effectively.
