Detailed Implementation

[0060] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.

[0061] According to the first aspect of this application, referring to Figures 1 to 15 This disclosure provides a power transfer gun 100. The power transfer gun 100 includes a tail cap 300, a wiring harness 400, and a connecting structure 500. The wiring harness 400 passes through the tail cap 300. The connecting structure 500 connects to the wiring harness 400 and engages with the tail cap 300 to restrict relative movement between the wiring harness 400 and the tail cap 300.

[0062] Since the connecting structure 500 and the tail cover 300 are snapped together, the snapping method is simple and convenient. This allows the connecting structure 500 and the tail cover 300 to be assembled without the aid of tools, such as screwdrivers, thus simplifying the assembly process.

[0063] There are many ways in which the connecting structure 500 and the tail cover 300 are engaged. In some embodiments, the tail cover 300 includes a cover body 310 and a first buckle 320 disposed on the cover body 310, the wire harness 400 passes through the cover body 310, and the connecting structure 500 is provided with a first slot 530, with the first buckle 320 engaging with the first slot 530. However, this design is not limited to this. In some other embodiments, the tail cover 300 is provided with a third slot, and the connecting structure 500 is configured as a third buckle, with the third buckle engaging with the third slot.

[0064] There are many structural forms of the first slot 530. In some embodiments, in the first direction, the connecting structure 500 includes a first limiting part 510 and a second limiting part 520 arranged sequentially and at intervals, and the first limiting part 510 and the second limiting part 520 are spaced apart in the first direction to form the first slot 530.

[0065] However, this design is not limited to this. In some other embodiments, a first slot 530 is formed on the end side of the connecting structure 500 in the first direction.

[0066] In some embodiments, the first latch 320 contacts the first limiting portion 510 in a direction opposite to the first direction. Thus, the first latch 320 reduces the amount of movement of the connecting structure 500 in the first direction, thereby reducing the amount of movement of the wire harness 400 in the first direction and suppressing any shifting of the wire harness 400 in the first direction.

[0067] However, this design is not limited to this. The first buckle 320 is movably disposed between the first limiting part 510 and the second limiting part 520.

[0068] In some embodiments, the first latch 320 presses against the first limiting portion 510.

[0069] Thus, the first latch 320 further reduces the amount of movement of the connecting structure 500 in the first direction, thereby further reducing the amount of movement of the wire harness 400 in the first direction, and further suppressing the movement of the wire harness 400 in the first direction.

[0070] In addition, when the connecting structure 500 and the tail cover 300 are to rotate relative to each other, a large frictional force can be generated between the first buckle and the first limiting part 510 to prevent the connecting structure 500 and the tail cover 300 from rotating relative to each other.

[0071] In some embodiments, the tail cap 300 further includes a third limiting portion 340 disposed on the cap body 310, and in a first direction, the third limiting portion 340 contacts the second limiting portion 520.

[0072] Thus, the third limiting part 340 reduces the amount of movement that the connecting structure 500 can move in the direction opposite to the first direction, thereby reducing the amount of movement that the wire harness 400 can move in the direction opposite to the first direction, and thus suppressing the movement of the wire harness 400 in the direction opposite to the first direction.

[0073] In some embodiments, the third limiting portion 340 presses against the second limiting portion 520.

[0074] Thus, the third limiting part 340 further reduces the amount of movement of the connecting structure 500 in the direction opposite to the first direction, thereby further reducing the amount of movement of the wire harness 400 in the direction opposite to the first direction. That is, it further suppresses the movement of the wire harness 400 in the direction opposite to the first direction.

[0075] Furthermore, when the connecting structure 500 and the tail cover 300 are to rotate relative to each other, a large frictional force can also be generated between the third limiting part 340 and the second limiting part 520 to prevent the connecting structure 500 and the tail cover 300 from rotating relative to each other.

[0076] The relative positions of the third limiting part 340 and the first slot 530 are numerous. In some embodiments, the second limiting part 520 includes a fourth limiting part 522 and a fifth limiting part 523, with the fourth limiting part 522 and the fifth limiting part 523 connected. In the first direction, the fourth limiting part 522 is disposed opposite to the first limiting part 510 to space out the first slot 530. In the first direction, the fifth limiting part 523 is offset from the first limiting part 510, and the third limiting part 340 abuts against the fifth limiting part 523. However, this design is not limited to this. In some other embodiments, the third limiting part 340 is disposed within the first slot 530.

[0077] In some embodiments, multiple first buckles 320 are provided, and the multiple first buckles 320 are arranged at intervals along the circumference of the wire harness 400. This helps to make the connection structure 500 more evenly stressed.

[0078] In some embodiments, multiple third limiting portions 340 are provided, and the multiple third limiting portions 340 are arranged at intervals along the circumference of the wire harness 400. This facilitates a more uniform force distribution on the connecting structure 500.

[0079] In some embodiments, the first latch 320 and the third limiting part 340 are alternately arranged in the circumferential direction of the wire harness 400. This helps to ensure that the connecting structure 500 is subjected to more uniform force.

[0080] In some embodiments, the third limiting portion 340 includes a limiting body 341 and a reinforcing portion 342. One end of the limiting body 341 is connected to the inner circumferential surface of the cover 310, and the other end is connected to the reinforcing portion 342, which is disposed on the cover 310. Thus, under the reinforcement of the reinforcing portion 342, the third limiting portion 340 is less likely to break when it is pressed against the second limiting portion 520.

[0081] In some embodiments, the third limiting portion 340 further includes a limiting protrusion 343 disposed on the reinforcing portion 342. In a first direction, the limiting protrusion 343 extends beyond the limiting body 341 and is used to press against the third limiting portion 340 in the first direction.

[0082] In this way, when the connecting structure 500 and the tail cover 300 need to rotate relative to each other, a large frictional force can also be generated between the limiting protrusion 343 and the third limiting part 340 to prevent the connecting structure 500 and the tail cover 300 from rotating relative to each other.

[0083] In some embodiments, the tail cap 300 further includes an anti-rotation portion 350 disposed on the cap body 310. The anti-rotation portion 350 is disposed opposite to the connecting structure 500 in the circumferential direction of the wire harness 400 to restrict the circumferential rotation of the connecting structure 500 around the wire harness 400. This helps to suppress relative rotation between the wire harness 400 and the tail cap 300.

[0084] There are many structural forms of the anti-rotation part 350. In some embodiments, the anti-rotation part 350 is provided with an anti-rotation groove 351, which is prismatic in shape. A connecting structure 500 is provided in the anti-rotation groove 351, and the outer peripheral surface of the connecting structure 500 is engaged with the groove sidewall of the anti-rotation groove 351.

[0085] In one example, the anti-rotation groove 351 is in the shape of a triangular prism, a quadrangular prism, a pentagonal prism, a hexagonal prism, a heptagonal prism, or an octagonal prism, etc., and there is no limitation here.

[0086] However, this design is not limited to this. In some other embodiments, the structure of the anti-rotation part 350 can also be other, which is not limited here, as long as the anti-rotation part 350 can limit the rotation of the connecting structure 500.

[0087] In some embodiments, the first slot 530 is configured as a first annular groove, which surrounds the wire harness 400 circumferentially. This helps to reduce the difficulty of the first latch 320 engaging with the first slot 530.

[0088] In some embodiments, the outer surface of the cover 310 is provided with positioning holes 311 for tooling fixtures to engage. This helps to improve the level of automation in the assembly process of the power transmission gun 100.

[0089] In some embodiments, the power transmission gun 100 further includes a gun housing 200, and a tail cover 300 is detachably connected to the tail of the gun housing 200. In this way, if the tail cover 300 is damaged, only the tail cover 300 needs to be replaced, without having to replace the gun housing 200 as well, which helps to reduce the maintenance cost of the power transmission gun 100.

[0090] In some embodiments, the tail cap 300 snaps into the gun housing 200. This makes assembly of the tail cap 300 and the gun housing 200 simple and convenient.

[0091] There are many ways to snap the tail cover 300 and the gun case 200 together. In some embodiments, the tail cover 300 includes a cover body 310 and a second buckle 330 provided on the cover body 310. The outer peripheral surface of the gun case 200 is provided with a second slot 210, and the second buckle 330 snaps into the second slot 210.

[0092] However, this design is not limited to this. In some other embodiments, the inner circumferential surface of the gun casing 200 is provided with a fourth slot, and the second buckle 330 engages with the fourth slot.

[0093] In some embodiments, the outer peripheral surface of the gun casing 200 is further provided with a guide groove 220 communicating with the second latch 210, and the second latch 330 can slide into the second latch 210 along the guide groove 220. In this way, the guide groove 220 provides guidance for the second latch to slide into the second latch 210, which helps to reduce the difficulty of the second latch engaging with the second latch 210.

[0094] In some embodiments, a seal 600 is provided between the connecting structure 500 and the inner wall of the gun housing 200. This helps to prevent water from flowing from the tail cap 300 along the gap between the connecting structure 500 and the gun housing 200 into the head of the gun housing 200, thereby reducing the possibility of short circuits in the electrical components located at the head of the gun housing 200.

[0095] In some embodiments, the seal 600 is detachably connected to the connection structure 500.

[0096] In this way, when the seal 600 is damaged, only the seal 600 needs to be replaced, without having to replace the connecting structure 500 as well, which helps to reduce the maintenance cost of the power transmission gun 100.

[0097] In some embodiments, the connecting structure 500 is provided with a second annular groove 521, and the sealing member 600 is provided in the second annular groove 521.

[0098] Thus, the second annular groove 521 provides a clear installation position for the seal 600. Users can quickly align and insert it during installation without repeated adjustments, greatly simplifying the installation process.

[0099] The connecting structure 500 can be made of various materials. In some embodiments, the connecting structure 500 is configured as an overmolded part or an injection molded part.

[0100] In some embodiments, the connecting structure 500 and the sealing element 600 are vulcanized integrally.

[0101] In some embodiments, the connection structure 500 is integrally formed with the outer surface of the wire harness 400.

[0102] In some embodiments, the power transmission gun 100 further includes a reinforcing element disposed within the connection structure 500.

[0103] This helps to improve the rigidity of the connecting structure 500, making it less prone to damage during the assembly of the connecting structure 500 with the tail cover 300.

[0104] Furthermore, in one example, it is beneficial to enhance the sealing rigidity of the seal 600.

[0105] In some embodiments, the reinforcement may be, but is not limited to, a metal structure or a plastic structure, and no limitation is made herein.

[0106] In some embodiments, the connecting structure 500 is fixedly connected to the wire harness 400. Thus, the tail cap 300 can limit the wire harness 400 by using the connecting structure 500.

[0107] It is understood that the power transmission gun 100 also includes a controller 700 disposed within the gun housing 200, and a wiring harness 400 connected to the controller 700. The tail cap 300 restricts the wiring harness 400 through the connecting structure 500, which helps to reduce the occurrence of the wiring harness 400 pulling on the controller 700 under external force, thereby making the connection between the wiring harness 400 and the controller 700 more stable.

[0108] According to a second aspect of this disclosure, a charging station is provided, which includes the aforementioned power transmission gun 100. This charging station possesses all the beneficial effects of the aforementioned power transmitter, which will not be elaborated further herein.

[0109] The power transmission gun 100 can transmit power from the charging pile to the equipment in use.

[0110] According to a third aspect of this disclosure, a vehicle is provided that includes the aforementioned power transmission gun 100. This vehicle possesses all the beneficial effects of the aforementioned power transmitter, which will not be elaborated further herein.

[0111] The power transfer gun 100 can transfer power from the vehicle to the electrical equipment in use; and / or, the charging gun can transfer power from the charging station to the vehicle.
