Abstract
Description
Technical Field
[0001] The present invention belongs to the technical field of charging gun devices, and particularly relates to a component structure compatible with an integrated gun shell and a split gun shell. Background Art
[0002] With the development of new energy electric vehicles, the protection requirements for charging guns are getting higher and higher. The basic components of a charging station are a charging gun and a charging pile. The charging pile transmits high-voltage electricity to the charging gun through a cable for the electric vehicle to charge. Most of the tail sealing structures of the charging guns on the market are in the form of gland head sealing. During the charging process, the charging gun cable moves with the charging gun, and a seal needs to be formed between the tail of the charging gun and the housing of the charging gun.
[0003] Currently, the IEC 62196 standard has clear requirements for product protection and interface structure.
[0004] When used outdoors, after the vehicle connector is inserted into the vehicle socket, its protection level should reach IP44, and the protection level of the vehicle connector should reach IP24. However, the charging guns designed according to the minimum protection level in the standard far fail to meet the requirements for long-term outdoor use. In case of heavy rain, the interfaces of the AC charging guns are soaked in water for a long time, posing a risk of protection failure and water ingress leading to high-voltage short circuit. Therefore, it is necessary to improve the protection level to reach the IP67 protection level.
[0005] The structure in the front insulating plate can be mainly divided into two parts. One part is the interface required by the standard, and the other part is the structure that cooperates with other parts of the product. Since the former is defined by the standard, it can be considered a general standard part, while the latter will result in the product being only in a split or integrated structure due to the styling requirements of the customer, thus causing a large amount of development of the front insulating plate. Therefore, it is necessary to carry out a generalization design for the front insulating plate assembly to increase the applicable range of the front insulating plate. Summary of the Invention

[0065] In order to achieve the fixed connection between the front insulating plate and the shell, a plurality of buckles 1-3 are provided on the outer wall of the rear end of the embedded tube of the front insulating plate 1, and an insert nut 1-4 is provided on the outer wall of the rear end of the embedded tube. The insert nut 1-4 is injection-molded in the front insulating plate 1. The front insulating plate 1 is fixed to the shell 6 through the buckles 1-3.
[0066] Notches 1-5 are provided on the outer wall at the joints with different radii of the embedded pipe. When the housing 6 is assembled with the front insulating plate 1, the housing sealing ring 5 is installed on the notches 1-5 to achieve the seal between the housing 6 and the front insulating plate 1. A plurality of front insulating plate bayonets 1-6 are provided on the outer wall at the front end of the embedded pipe.
[0067] The core component installation inner cavity of the front insulating plate 1 is required to be designed based on "IEC 62196-2: 2016", P37-38. From the figure, there are a total of 7 inner cavities: there are two smaller inner cavities above, which are signal core components for transmitting signals; there are 5 larger inner cavities below, which are power supply and grounding core components for conveying current and grounding.
[0068] For the structure of the core component 2, see Figure 4 As shown, a cable crimping cylinder 2-1 is provided at the front end of the core component 2;; A positioning surface 2-2 and an anti-rotation flat position 2-3 are provided at the rear end of the cable crimping cylinder 2-1. The cable crimping cylinder 2-1 is placed in the inner cavity 4-1 of the rear insulating plate. A sealing outer circle 2-4 is also provided at the rear end of the anti-rotation flat position 2-3. During assembly, the core component sealing ring 3 is installed on the sealing outer circle 2-4.
[0069] For the structure of the rear insulating plate 4, see Figure 5 As shown, a rear insulating plate inner cavity 4-1 is provided in the middle at the front end of the rear insulating plate 4. A core component positioning surface 4-2 and a core component anti-rotation flat position 4-3 are provided on the inner wall of the rear insulating plate inner cavity 4-1. When the core component 2 is assembled into the rear insulating plate inner cavity 4-1, the positioning surface 2-2 on the core component 2 cooperates with the core component positioning surface 4-2 for stopping, and the anti-rotation flat position 2-3 cooperates with the core component anti-rotation flat position 4-3 for anti-rotation.
[0070] For the structure of the rear end of the rear insulating plate 4, see Figure 6 As shown, a plurality of rear insulating plate buckles 4-4 are provided around the rear edge of the rear insulating plate 4; A rear insulating plate positioning rib 4-5 is also provided beside the rear insulating plate buckle 4-4. The insulating plate buckle 4-4 on the rear insulating plate 4 matches the front insulating plate buckle groove 1-4 on the front insulating plate 1. The rear insulating plate 4 is fixed to the front insulating plate 1 by the engagement of the rear insulating plate buckle 4-4 and the front insulating plate buckle groove 1-4.
[0071] For the structure of the housing 6, see Figures 7-8 As shown, the housing 6 is of an integral structure. A housing sealing inner cavity 6-3 for the cable 8 to pass through is provided along the axis at the center of the housing 6. A housing buckle groove 6-4 is provided on the inner wall of the front end inner cavity of the housing 6. The housing buckle groove 6-4 matches the buckle 1-3 on the front insulating plate 1. The front insulating plate 1 is fixed to the housing 6 by the engagement of the buckle 1-3 and the housing buckle groove 6-4.
[0072] On the inner wall of the front end cavity of the housing 6, below the housing snap groove 6-4, there are also multiple housing circumferential limiting ribs 6-2. The multiple housing circumferential limiting ribs 6-2 are arranged in a circle along the inner wall surface. On the inner wall of the front end cavity of the housing 6, below the housing circumferential limiting ribs 6-2, there are also multiple groups of housing positioning ribs 6-1. The multiple groups of housing positioning ribs 6-1 are arranged in a circle along the inner wall surface. The housing positioning ribs 6-1 are used to fix the rear end of the rear insulating plate 4, and the housing circumferential limiting ribs 6-2 are used to fix the outer ring of the embedded tube of the front insulating plate 1 to prevent the rotation of the front insulating plate 1. When the rear insulating plate 4 is assembled with the housing 6, the rear insulating plate positioning rib 4-5 at the rear end of the rear insulating plate 4 cooperates with the housing positioning rib 6-1 in the housing sealing cavity 6-3 of the housing 6 to prevent the front and rear movement of the rear insulating plate 4.
[0073] On the outer wall of the front end of the housing 6, there is an axial position screw hole 6-5. When the housing 6 is assembled with the front insulating plate 1, the axial position screw hole 6-5 is aligned with the insert nut 1-4 on the front insulating plate 1. The housing 6 is fixed to the rear end of the front insulating plate 1 by screwing the axial position screw 7 through the axial position screw hole 6-5 into the insert nut 1-4 and tightening.
[0074] For the structure of the cable 8, refer to Figure 9 as shown. The cable 8 includes a cable core wire 8-1, a core wire insulation 8-2 wrapping the cable core wire 8-1, and an outer sheath 8-3 wrapping the core wire insulation 8-2.
[0075] The following is a further description of the assembly relationship between the parts of the integrated gun housing:
[0076] For the structure of the cable 8, refer to Figure 9 as shown. At the front end of the cable 8, the outer sheath 8-3 and the core wire insulation 8-2 are stripped off to expose the internal cable core wire 8-1.
[0077] The front end of the cable 8 is passed through the housing sealing cavity 6-3 of the housing 6.
[0078] Then the front end cable core wire 8-1 of the cable 8 is passed through the rear insulating plate inner cavity 4-1 of the rear insulating plate 4.
[0079] The core component sealing ring 3 is installed on the sealing outer circle 2-4 and sealed with the core component sealing inner cavity 1-2.
[0080] Then it is crimped with the cable crimping cylinder 2-1 on the core component 2. The cable crimping cylinder 2-1 on the core component is placed into the rear insulating plate inner cavity 4-1 of the rear insulating plate 4. The positioning surface 2-2 has a clearance fit with the core component positioning surface 4-2; the anti-rotation flat position 2-3 has an interference fit with the core component anti-rotation flat position 4-3, preventing the core component 2 from falling off the rear insulating plate 4 during assembly and preventing the core component from twisting after assembly.
[0081] The housing sealing ring 5 is installed in the notch 1-5 and the housing sealing inner cavity 6-3 for sealing.
[0082] Then, the front end of the rear insulating plate 4 is inserted into the sealing inner cavity 1-7 of the front insulating plate 1. At this time, the rear insulating plate 4 and the core component 2 are almost integrated, and they are placed into the front insulating plate 1 and pre-fixed through the front insulating plate bayonet 1-6 and the rear insulating plate buckle 4-4. The front insulating plate bayonet 1-6 and the rear insulating plate buckle 4-4 only function to prevent the rear insulating plate 4 from slipping out of the front insulating plate 1 during assembly and have no actual positioning function after assembly is completed.
[0083] The cable 8 is retracted, and then the front insulating plate 1 is assembled into the housing 6. The rear insulating plate positioning rib 4-5 and the housing positioning rib 6-1 are in clearance fit; the buckle 1-3 is connected and fixed to the housing buckle groove 6-4. The circumferential limiting rib 6-2 of the housing is used to fix the outer ring of the embedded pipe of the front insulating plate 1 to prevent the rotation of the front insulating plate 1; then, the shaft position screw 7 is passed through the shaft position screw hole 6-5 and rotated into the insert nut 1-4 and tightened to fix the front end of the housing 6 and the rear end of the front insulating plate 1. At this time, the positioning surface 2-2 and the core component positioning surface 4-2 are in clearance fit.
[0084] For the structure after installation, see Figure 10 As shown, from front to back, the front insulating plate 1, the core component 2, the rear insulating plate 4, and the housing 6 are tightly connected in sequence.
[0085] The split gun housing is designed based on the "IEC 62196-2: 2016" standard. For the specific structure, see Figures 11-16 As shown, it includes a front insulating plate 1, a core component 2, a core component sealing ring 3, a rubber-coated rear insulating plate 9, a left housing 10, and a right housing 11.
[0086] For the structure of the rubber-coated rear insulating plate 9, see Figure 12 As shown, it is made by secondary injection molding of TPU or TPE elastomer material on the rear insulating plate 4. The rubber-coated rear insulating plate 9 includes the rear insulating plate 4 and an elastic soft rubber shell installed at the rear end of the rear insulating plate 4. Cable sealing holes 9-1 corresponding to the inner cavity 4-1 of the rear insulating plate are provided on the elastic soft rubber shell. Front insulating plate inner cavity sealing rib strips 9-2 are provided on the end face of the rear end of the rear insulating plate 4, and the front insulating plate inner cavity sealing rib strips 9-2 seal between the rear end of the rear insulating plate 4 and the sealing inner cavity (1-7).
[0087] Both the left housing 10 and the right housing 11 are semi-shell structures. For the structure of the left housing 10, see Figure 13 As shown, for the structure of the left housing 10, see Figure 14As shown in the figure, on the front end wall surface of the left housing, left positioning rib strips 10-1 are arranged circumferentially, multiple left circumferential limiting ribs 10-2 are arranged axially, multiple groups of left positioning ribs 10-3 are arranged axially, and a plurality of left self-tapping screw holes 10-4 are provided at the front and rear ends of the left housing for fixedly connecting with the right housing 11.
[0088] For the structure of the right housing 11, refer to Figure 15 As shown in the figure, on the front end wall surface of the right housing 11, right positioning rib strips 11-4 are arranged circumferentially, multiple right circumferential limiting ribs 11-2 are arranged axially, multiple groups of right positioning ribs 11-3 are arranged axially, and a plurality of right self-tapping studs 11-1 are provided at the front and rear ends of the right housing for fixedly connecting with the left housing 10.
[0089] The self-tapping screw 12 passes through the left self-tapping screw hole 10-4 and the right self-tapping stud 11-1 to fixedly connect the left and right housings.
[0090] After the left housing 10 and the right housing 11 are assembled, they are the same as the middle housing structure of the integrated gun housing. The assembly relationship between the parts of the split gun housing is the same as that of the integrated gun housing. For the structure after installation, refer to Figure 16 As shown in the figure, from front to back, the front insulating plate 1, the core component 2, the rubber-coated rear insulating plate 9, the left housing 10, and the right housing 11 are tightly connected in sequence.
[0091] From the structures of the integrated and split gun housings of the present invention, it can be seen that the front insulating plate 1, the core component 2, the core component sealing ring 3, the rear insulating plate 4, etc. can be common to the integrated and split gun housings.
[0092] In the present invention, for the integrated charging gun, only by adding the upper housing sealing ring 5 can the IP67 of the front end of the housing be achieved. For the split gun housing, only by replacing the rear insulating plate 4 with the rubber-coated rear insulating plate 9 can the good effect of IP67 be achieved: the use of common parts reduces the R & D cost of the product; IP67 greatly enhances the safety of the product.
[0093] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and modifications can be made, and these improvements and modifications should also be regarded as the protection scope of the present invention.
