[0052] In the present invention, descriptions such as "first" and "second" are only used for descriptive purposes and do not specifically refer to the order or sequence, nor are they used to limit the present invention. They are only used to distinguish between protective components or operations described with the same technical terms, and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one such feature. In addition, the technical solutions and technical features between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in this field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0053] Example 1:

[0054] Please refer to Figures 1-8A charging harness assembly that can be used for new energy commercial vehicles includes a charging pile side wall 1 and a charging gun 2. The charging gun 2 is connected to the charging pile side wall 1 through a wiring harness 4. A mounting assembly is provided on the charging pile side wall 1, and the mounting assembly is used to mount the charging gun 2. A safety component is provided on the charging pile side wall 1, and the safety component is connected to the mounting assembly. When the mounting assembly is started, the safety component blocks the wiring harness 4, and when the mounting assembly is not started, the safety component conducts the wiring harness 4.

[0055] The working principle and beneficial effects of the above scheme are as follows:

[0056] This application adds a safety component and a mounting component to the traditional charging component. Through the mechanical linkage of the safety component and the mounting component, when the charging gun 2 is mounted on the mounting component, the safety component is triggered to block the wiring harness 4, so that the wiring harness 4 is powered off. Compared with the control at the single software level, this application adds mechanical hardware control. When the system software fails, the wiring harness 4 is still not connected, which enhances safety. When the charging gun 2 is unplugged, the charging gun 2 is detached from the mounting component. At this time, the safety component connects the wiring harness 4 to ensure charging conditions.

[0057] Example 2:

[0058] Please refer to Figures 1-4 On the basis of Example 1, the safety component includes a fixed block 6, which is fixedly connected to the side wall 1 of the charging pile. A pressure block 5 is slidably connected to the fixed block 6. The lower end of the fixed block 6 is fixedly connected to an elastic cavity 7. A return spring is provided in the elastic cavity 7. The upper end of the return spring is connected to the lower end of the pressure block 5.

[0059] The upper ends of the pressing block 5 and the fixing block 6 are both provided with grooves for accommodating the charging gun 2 .

[0060] The pressure block 5 is fixedly connected to a follower rod 9, which passes through the side wall 1 of the charging pile, and the follower rod 9 is slidably connected to the side wall 1 of the charging pile, and the end of the follower rod 9 away from the pressure block 5 is rotatably connected to the upper end of the linkage rod 8, and the lower end of the linkage rod 8 is fixedly connected to a linkage member 10, and the linkage member 10 is in a "7" shape, and a positioning plate 11 is provided on the inner side of the linkage member 10, and the positioning plate 11 is fixedly connected to the side wall 1 of the charging pile, and a first pressure rod 14 is slidably connected to the positioning plate 11, and the first pressure rod 14 is provided with an arc pressure head at one end facing the linkage member 10, and a first spring 13 is provided between the pressure head and the positioning plate 11, and the first spring 13 is sleeved on the first pressure rod 14, and the end of the first pressure rod 14 away from the linkage member 10 is fixedly connected to a trigger head 12, and the trigger head 12 is located between the positioning plate 11 and the side wall 1 of the charging pile, and two separate sets of contacts are provided on the side of the charging pile side wall 1 facing the trigger head 12;

[0061] The two groups of contacts are respectively connected to the wiring harness 4 and the power supply.

[0062] The working principle and beneficial effects of the above scheme:

[0063] When the charging gun 2 is mounted on the mounting assembly, the charging gun 2 drives the pressure block 5 to move downward, overcoming the elastic force of the return spring. The follower rod 9 and the linkage rod 8 drive the linkage member 10 to move downward. The downward movement of the linkage member 10 releases the restriction on the first pressure rod 14. Under the action of the first spring 13, the trigger head 12 moves and disconnects from the two sets of contacts on the side wall 1 of the charging pile, disconnecting the wiring harness 4 from the power supply, ensuring safety after charging is completed.

[0064] When the charging gun 2 is removed, the pressure block 5 moves upward under the elastic force of the return spring, and drives the linkage part 10 to move upward through the follower rod 9 and the linkage rod 8. The upward movement of the linkage part 10 causes the oblique side of the linkage part 10 to squeeze the first pressure rod 14, overcoming the elastic force of the first spring 13, and the trigger head 12 approaches the side wall 1 of the charging pile, releasing the two sets of contacts on the side wall 1 of the charging pile, connecting the wiring harness 4 with the power supply, and ensuring the smooth flow of the charging current.

[0065] Example 3:

[0066] Please refer to Figure 5-Figure 8 On the basis of Example 1, the mounting assembly includes a fixing plate 15, which is fixedly connected to the side wall 1 of the charging pile. A first slide groove 16 is provided on the fixing plate 15, and a first fixed slider 17 and a second fixed slider 18 are slidably connected to the first slide groove 16. The first fixed slider 17 and the second fixed slider 18 are both fixedly connected to the handle 3, and the handle 3 is fixedly connected to the charging gun 2.

[0067] A clamping block 20 is slidably connected to the fixed plate 15 , and the sliding direction of the clamping block 20 is perpendicular to the sliding direction of the first fixed slider 17 and the second fixed slider 18 ;

[0068] The side of the clamping block 20 is fixedly connected to one end of the fourth spring 27, and the other end of the fourth spring 27 is fixedly connected to the fixing plate 15;

[0069] An extrusion hole 26 is provided at the center of the clamping block 20;

[0070] A second pressure rod 23 is inserted into the fixing plate 15 and passes through the extrusion hole 26. A wedge block 24 is fixedly connected to the second pressure rod 23. The oblique edge of the wedge block 24 can be pressed against the side of the extrusion hole 26.

[0071] One end of the second pressure rod 23 located outside the fixing plate 15 is fixedly connected to the button 21 . A third spring 22 is provided between the button 21 and the fixing plate 15 . The third spring 22 is sleeved on the second pressure rod 23 .

[0072] A second spring 19 is fixedly connected to one end of the fixing plate 15 away from the button 21 , and the second spring 19 can contact the second fixing slider 18 .

[0073] A locking ear 25 is fixedly connected to the wedge-shaped block 24 , and a locking right angle is formed between the locking ear 25 and the wedge-shaped block 24 .

[0074] The working principle and beneficial effects of the above scheme are as follows:

[0075] When mounting the charging gun 2, first slide the first fixed slider 17 and the second fixed slider 18 fixed by the handle 3 on the charging gun 2 into the first slide groove 16, and then continue to slide downward to squeeze the second spring 19 until the first fixed slider 17 exceeds the clamping block 20. The clamping block 20 rebounds under the action of the fourth spring 27, clamping the first fixed slider 17, which can effectively prevent the charging gun 2 from falling off.

[0076] To remove the charging gun 2, the button 21 needs to be pressed, squeezing the third spring 22. The second pressure rod 23 drives the wedge block 24 to move. The oblique edge of the wedge block 24 slides along the squeezing hole 26, driving the clamping block 20 to move into the fixed plate 15, releasing the restriction on the first fixed slider 17. Under the action of the second spring 19, the charging gun 2 is ejected, making it easier to remove.

[0077] When the first fixed slider 17 is engaged by the engaging block 20 , the charging gun 2 contacts the fixing block 6 . At this time, the linkage member 10 is located at the bottom, releasing the restriction on the first pressing rod 14 .

[0080] A protective cover 30 is provided on the outer side of the first charging connector 28 .

[0081] A cover plate 34 is provided on the second charging connector 32. A rod 42 is slidably connected between the cover plate 34 and the second charging connector 32. A seventh spring 54 is sleeved on the rod 42. One end of the seventh spring 54 is engaged with the rod 42, and the other end of the seventh spring 54 abuts against the cover plate 34.

[0082] The insertion rod 42 is provided with a locking groove 43;

[0083] A pull ring 35 is slidably inserted on the cover plate 34 , and a slot 36 is fixedly connected to the pull ring 35 . The slot 36 passes through the cover plate 34 and can be inserted into the locking groove 43 .

[0084] The pull ring 35 is provided with a second sliding groove 37, in which a sliding plate 38 is slidably connected. The sliding plate 38 is slidably sleeved on a positioning rod 40, and the positioning rod 40 is fixedly connected to the cover plate 34;

[0085] A fifth spring 39 is provided on the end of the slide 38 and the positioning rod 40 away from the cover plate 34 , and both ends of the fifth spring 39 abut against the slide 38 and the end of the positioning rod 40 away from the cover plate 34 ;

[0086] A limit block 44 is provided on the insertion rod 42;

[0087] A buckle 41 is provided on one end of the cover plate 34 facing the contact head 33 .

Two sets of slides 51 are slidably connected to the slide bars 47. A sixth spring 48 is provided between the slides 51 and the fixed platform 45. The sixth spring 48 is sleeved on the slide bar 47.

[0089] The slide 51 is rotatably connected to one end of the linkage rod 52, and the other end of the linkage rod 52 is rotatably connected to the protective cover 30;

[0090] A socket 46 is provided on the fixing platform 45 near one end of the charging chamber 29;

[0091] A flexible fixing sheet 49 is fixedly connected to the fixing platform 45 near one end of the charging chamber 29. The flexible fixing sheets 49 are symmetrically arranged in two groups. A bending clamping plate 50 is fixedly connected between the two groups of flexible fixing sheets 49. A clamping platform is provided on the side of the bending clamping plate 50.

[0095] The working principle and beneficial effects of the above scheme are as follows:

[0096] When charging is not in progress, the protective cover 30 can cover the outside of the charging cavity 29, protecting the charging cavity 29 from corrosion by rain and dust, and ensuring the service life of the first charging connector 28. When charging is in progress, it is only necessary to pull the pull ring 35, and the pull ring 35 disengages from the positioning groove 43, releasing the restriction on the insertion rod 42. The insertion rod 42 pops out under the action of the seventh spring 54, and the insertion rod 42 is inserted into the insertion hole 46. The insertion rod 42 squeezes the bending card 50, and the bending card 50 bends under the action of external force. The bending card 50 loses the restriction on the slide 51, and the bending card 50 slides out of the retraction hole 53. The slide 51 moves toward the middle under the action of the sixth spring 48, and drives the protective cover 30 to open through the connecting rod 52, exposing the charging cavity 29, and continues to insert the contact head 33 inward to complete the charging connection;

[0097] When the contact head 33 is inserted into the charging cavity 29, the buckle 41 will be locked on the fixing platform 45 to ensure the stable connection between the first charging connector 28 and the second charging connector 32;

[0098] After charging is completed, the protective cover 30 is squeezed by external force, and the protective cover 30 is closed. The bent clamping plate 50 passes through the retraction hole 53 again and engages with the slide 51 to maintain the closed state of the protective cover 30.

[0099] After charging is completed, the rod 42 is squeezed inward so that the latching slot 36 is again engaged with the latching slot 43 , thereby completing the recovery of the rod 42 .
