[0035] Figure 1 This illustration shows a side view of the high-voltage connector locking structure 100 provided in the first aspect embodiment of this application. Figure 2 This illustration shows a side view of the socket structure 10 of the high-voltage connector locking structure 100 provided in the first aspect embodiment of this application. Figure 3This illustration shows a side view of the plug structure 20 and the latching structure 30 assembled in the high-voltage connector locking structure 100 provided in the first aspect embodiment of this application. Figure 4 The overall structure of the locking structure 30 of the high-voltage connector locking structure 100 provided in the first aspect embodiment of this application is shown.

[0036] Please see Figures 1 to 4 In one aspect, embodiments of this application provide a high-voltage connector locking structure, including a socket structure 10, a plug structure 20, and a locking structure 30.

[0037] The socket structure 10 includes a socket body 11 and a toothed structure 12 disposed on one side surface of the socket body 11. The toothed structure 12 includes at least two teeth 121 of different sizes.

[0038] The socket structure 10 includes a plug body 21 and a rotating shaft 22 extending from one side of the plug body 21. The plug body 21 and the socket body 11 are pluggable and detachable.

[0039] The locking structure 30 includes a locking body 31 and a lower pressure arm 32 extending from the locking body 31. The locking body 31 is sleeved on the rotating shaft 22 and the locking structure 30 rotates around the rotating shaft 22. The locking body 31 also includes at least two insert teeth 313 of different sizes. The insert teeth 313 are coupled to the tooth groove 121 in a one-to-one correspondence.

[0040] The high-voltage connector locking structure 100 provided in the first aspect of this application requires that the toothed grooves 121 and the insert teeth 313 of different sizes be engaged in a one-to-one correspondence, and the locking structure 30 be rotated along the rotation axis 22 until the pressing arm 32 is pressed down and fits against the plug body 21, so that the plug body 21 and the socket body 11 can be assembled in place; when the plug body 21 and the socket body 11 are not assembled in place, the locking structure 30 cannot rotate smoothly and is suspended in the middle, and the pressing arm 32 cannot be pressed down smoothly and is raised, which serves as a warning and error prevention function.

[0041] The socket structure 10 is disposed on the surface of the device and is connected to the internal circuitry of the device.

[0042] One end of the plug structure 20 is connected to a cable, and the plug body 21 and the socket body 11 are pluggable and detachable, which is used to connect the cable to the internal circuit of the device to realize functions such as high voltage power supply.

[0043] For example, the two toothed grooves 121 of different sizes in the toothed groove structure 12 and the two toothed teeth 313 of different sizes in the locking body 31 in the locking structure 30 can cooperate with the rotation of the locking body 31 around the rotation axis 22 to first achieve pre-alignment and coupling between one of the toothed teeth 313 and the slot. Then, the locking body 31 rotates, and the remaining toothed teeth 313 and the slot are coupled in sequence, so that the plug body 21 can be smoothly inserted into the socket body 11 to complete the connection.

[0044] Optionally, the size of the insert teeth 313 and the slot that first come into contact, and the insert teeth 313 and the slot that are coupled and engaged in sequence as the latch body 31 rotates, gradually decreases. This is so that if the insert teeth 313 that first come into contact with the slot are not in the position of the corresponding slot, they cannot be inserted into the slot smoothly, and the pressing arm 32 is raised high, making the warning and error prevention function more effective.

[0045] The downward pressing arm 32 serves both as an assist handle and a warning mechanism to prevent errors. Since the downward pressing arm 32 extends from the locking body 31, the operator only needs to operate one end of the downward pressing arm 32. Through the lever principle, only a force a few times less than that required to rotate the locking body 31 is needed at one end of the downward pressing arm 32 to rotate the locking body 31 around the rotation axis 22, thereby achieving sequential coupling and engagement between the insert teeth 313 and the slot.

[0046] Meanwhile, since the insert teeth 313 and the slots are of different sizes, only after the insert teeth 313 and the slots of one-to-one corresponding sizes are coupled and engaged in sequence can the latch body 31 rotate smoothly around the rotating axis 22 and the pressing arm 32 press down smoothly.

[0047] When there is a mismatch between the insert tooth 313 and the slot, the insert tooth 313 cannot be inserted into the slot smoothly, the locking body 31 cannot rotate smoothly, and the lowering arm 32 tilts up, making it easy for the operator to observe the abnormality and realize the warning and error prevention function.

[0048] For example, rotating shafts 22 are distributed on both sides of the plug body 21, and the pressing arm 32 is sleeved on both sides of the rotating shafts 22 of the plug body 21, making the connection more stable.

[0049] Figure 5 The diagram shows a top view of the high-voltage connector locking structure 100 provided in the first aspect embodiment of this application. Figure 6 It shows Figure 5 Cross-sectional structure along the AA direction.

[0050] Please see Figures 5 to 6In some embodiments, the high-voltage connector locking structure 100 provided in the first aspect of this application includes a first state and a second state that can be switched between each other. In the second state, the plug body 21 is inserted into the socket body 11, the insertion teeth 313 mesh with their corresponding tooth grooves 121, and the lower pressing arm 32 includes an extension arm 321 and a lower pressing plate 322. The extension arm 321 extends from the locking body 31 and the lower pressing plate 322 is disposed at the end of the extension arm 321 away from the locking body 31. The lower pressing plate 322 is pressed down toward the plug body 21 and is disposed in contact with the surface of the plug body 21.

[0051] In these embodiments, the high-voltage connector locking structure 100 provided in the first aspect of this application, in the first state, when the plug body 21 is inserted into the socket body 11, the lower pressure plate 322 can achieve a surface setting that fits the plug body 21.

[0052] When the high-voltage connector locking structure 100 is assembled to achieve the corresponding function, there are two states.

[0053] In the first state, the socket body 11 and the plug body 21 are disconnected, thereby disconnecting the high-voltage line.

[0054] In the second state, the socket body 11 and the plug body 21 are inserted and engaged in place to achieve a stable connection of the high-voltage line. The lower pressure arm 32 is pressed down smoothly, and the lower pressure plate 322 is set to fit against the plug body 21.

[0055] When transitioning from the first state to the second state, it is only necessary to pre-align the socket body 11 and the plug body 21. The corresponding teeth 313 and slots are engaged, the locking body 31 rotates around the rotating shaft 22 and the pressing arm 32 is pressed down smoothly, the pressing plate 322 is set to fit the plug body 21, and the plug body 21 is inserted into the socket body 11 and connected in place.

[0056] When transitioning from the second state to the first state, simply tilt one end of the lower pressure plate 322 upwards, and the corresponding insert teeth 313 and slots of the same size and shape will engage. The locking body 31 will rotate around the rotation axis 22 in the opposite direction to release the plug body 21 and the socket body 11, thereby disconnecting the socket structure 10 from the plug structure 20.

[0057] The setting of the pressure plate 322 enables the pressure arm 32 to be adapted to the surface shape of the plug body 21, further enabling the pressure arm 32 to be pressed down smoothly into place, and realizing a smooth transition between the first state and the second state.

[0058] For example, rotating shafts 22 are distributed on both sides of the plug body 21, and the two sets of extension arms 321 and the locking body 31 of the locking structure 30 are both sleeved on the rotating shafts 22 and connected by the lower pressure plate 322.

[0059] Please continue reading. Figures 5 to 6 In some embodiments, the high-voltage connector locking structure 100 provided in the first aspect of this application further includes a locking pressure plate 23 in the plug structure 20. The locking pressure plate 23 slides along the surface of the plug body 21, and the locking structure 30 further includes a pressure plate groove 33 formed by the lower pressure plate 322 extending toward the side away from the locking body 31. In the second state, the locking pressure plate 23 slides to the locked position and is embedded in the pressure plate groove 33, locking the locking pressure plate 23 and the pressure plate groove 33 so that the lower pressure plate 322 is disposed in contact with the surface of the plug body 21.

[0060] In these embodiments, the high-voltage connector locking structure 100 provided in the first aspect of this application has a locking plate 23 that can fix the lower plate 322 in a position that fits against the surface of the plug body 21, thereby enabling manual locking and releasing of the lower plate 322.

[0061] For example, the sliding direction of the locking plate 23 intersects with the pressing direction of the locking structure 30 and the lower pressure plate 322. The locking plate 23 slides along the sliding direction to the position where it intersects with the pressing direction of the locking structure 30 and the lower pressure plate 322 to lock the pressure plate groove 33 of the lower pressure plate 322 with the locking plate 23.

[0062] Optionally, the locking plate 23 has a certain length, so the locking plate 23 only needs to slide along the sliding direction to a position near the intersection of the locking structure 30 and the pressing direction of the lower pressure plate 322 to achieve the locking of the pressure plate groove 33 of the lower pressure plate 322 with the locking plate 23.

[0063] Please continue reading. Figures 5 to 6 In some embodiments, the high-voltage connector locking structure 100 provided in the first aspect of this application includes a locking structure 30 further comprising a guide boss 34 extending from one side of the lower pressure plate 322, and a plug structure 20 further comprising a first guide groove 24 disposed on the surface of the plug body 21. In the second state, the guide boss 34 is embedded in the first guide groove 24.

[0064] In these embodiments, the high-voltage connector locking structure 100 provided in the first aspect of this application has a guide boss 34 that cooperates with the first guide groove 24, which further facilitates observation of whether the connection between the socket body 11 and the plug body 21 of the high-voltage connector locking structure 100 in the second state is in place.

[0065] For example, the guide boss 34 is consistent with the pressure plate groove 33 and is disposed in the pressure plate groove 33 formed by the lower pressure plate 322 extending toward the side away from the latch body 31.

[0066] Please see Figures 1 to 4 In some embodiments, the high-voltage connector locking structure 100 provided in the first aspect of this application has an extension arm 321 including an auxiliary groove 321a that extends through itself, and a plug structure 20 including an auxiliary limiting part 25 disposed on one side of the plug body 21. In the second state, the auxiliary limiting part 25 is embedded in the auxiliary groove 321a.

[0067] In these embodiments, the high-voltage connector locking structure 100 provided in the first aspect of this application, with the cooperation of the auxiliary groove 321a and the auxiliary limiting part 25, further facilitates observation from the side of the extension arm 321 whether the connection between the socket body 11 and the plug body 21 of the high-voltage connector locking structure 100 in the second state is in place.

[0068] For example, rotating shafts 22 are distributed on both sides of the plug body 21. The two sets of extension arms 321 of the locking structure 30 and the locking body 31 are both sleeved on the rotating shafts 22 and connected by the lower pressure plate 322. Two sets of auxiliary grooves 321a are provided on the two sides of the extension arms 321 of the locking structure 30. Two sets of auxiliary limiting parts 25 are provided on both sides of the socket body 11, so that it is convenient to observe from the extension arms 321 on both sides whether the connection between the high voltage connector locking structure 100 and the socket body 11 and the plug body 21 is in place in the second state.

[0069] Please see Figures 1 to 4 In some embodiments, the high-voltage connector locking structure 100 provided in the first aspect of this application further includes a second guide groove 13. The second guide groove 13 is disposed on one side surface of the socket body 11. In the second state, the plug body 21 is guided and inserted into the socket body 11 along the second guide groove 13.

[0070] In these embodiments, the high-voltage connector locking structure 100 provided in the first aspect of this application, the second guide groove 13 can help pre-align the plug body 21 and the socket body 11 in the second state and limit the installation direction of the plug structure 20 and the socket structure 10.

[0071] Please see Figure 4 and Figure 6 In some embodiments, the high-voltage connector locking structure 100 provided in the first aspect of this application further includes a first limiting part 311 and a second limiting part 312 in the locking body 31, and the insertion teeth 313 are disposed between the first limiting part 311 and the second limiting part 312.

[0072] In these embodiments, the high-voltage connector locking structure 100 provided in the first aspect of this application, with the first limiting part 311 and the second limiting part 312, further limits the range of the rotatable angle of the locking body 31, and further helps to confirm whether the connection between the socket body 11 and the plug body 21 of the high-voltage connector locking structure 100 in the second state is in place.

[0073] For example, the rotatable angle range between the first limiting part 311 and the second limiting part 312 is approximately 120°.

[0074] Please continue reading. Figure 4 and Figure 6 In some embodiments, the high-voltage connector locking structure 100 provided in the first aspect embodiment of this application, in the second state, both the first limiting part 311 and the second limiting part 312 are in contact with the socket body 11. During the pressing down of the lower pressure plate 322, the second limiting part 312 first abuts against the socket body 11, the second limiting part 312 rotates away from the socket body 11, the first limiting part 311 rotates towards the socket body 11 and comes into contact with the socket body 11, the first limiting part 311 slides along the surface of the socket body 11 until the lower pressure plate 322 is abutted against the surface of the plug body 21, and the first limiting part 311 is embedded in the limiting groove 14 on the surface of the socket body 11.

[0075] In these embodiments, the high-voltage connector locking structure 100 provided in the first aspect of this application has a second limiting part 312 that contacts the socket body 11 before the insertion teeth 313 and the slot, thus determining the initial posture of the locking structure 30. Subsequently, during the pressing process, the first limiting part 311 slides against the surface of the plug body 21, further helping the operator to confirm the intermediate posture of the locking structure 30. When the pressing plate 322 is set to fit against the surface of the plug body 21, the first limiting part 311 is embedded in the limiting groove 14 on the surface of the socket body 11, realizing the confirmation of the final posture when connected in place, further helping to confirm whether the connection between the socket body 11 and the plug body 21 of the high-voltage connector locking structure 100 is in place in the second state.

When the battery of the range-extended vehicle 300 is depleted, the range extender charges the battery of the vehicle 300 through the generator, thereby enhancing the driving range.

[0080] For example, the socket structure 10 in the high-voltage connector locking structure 100 is fixed to the housing of the generator controller 200, and the plug structure 20 and the locking structure 30 are connected to the cable on one side. The generator controller 200 ultimately controls and manages the high-voltage DC power to charge the battery through the cable.
