[0031] The technical solution of the present invention will be described in detail below through specific embodiments.

[0032] Example 1

[0033] like Figures 1-9 As shown, schematic diagrams of the overall and partial structures of the battery swapping connector with buffer function are presented.

[0034] The battery swapping connector includes a plug 1 and a socket 2. The plug 1 includes a plug panel 3 and a plug body 4. The plug body 4 is fixedly installed at the center of the plug panel 3. The plug body 4 is fixedly provided with male terminals 5 and signal pins 6. There are two male terminals 5 and one set of signal pins 6. The two male terminals 5 are arranged side by side above the plug body 4, and the signal pins 6 are located below the male terminals 5. One end of each of the two male terminals 5 is fixedly connected to a bolt, and the other end can be connected to the female terminal 10 on the socket 2. One end of the bolt is connected to the male terminal 5, and the other end can be connected to the battery pack on the new energy vehicle through a wire.

[0035] On the panel of plug 1, there are two guide posts 7 located below the plug body 4. They are located on the lower sides of the plug body 1.

[0036] The socket 2 includes a socket panel 8 and a socket body 9. The socket panel 8 has a socket body mounting through hole at its center. The socket body 9 is located in the socket body mounting through hole and is fixedly connected to the socket panel 8. The socket body 9 is fixedly provided with two female terminals 10 and one signal jack socket 17. The socket body 9 is adapted to the structure of the plug body 4. The male terminal 5 can be inserted into the female terminal 10, and the signal pin 6 can be inserted into the signal jack 12. Two guide post sleeves 13 are provided below the socket body 9. The guide post 7 can be inserted into the guide post sleeve 13.

[0037] The socket body 9 includes a housing 14, a female terminal 10, a base plate 15, a sleeve for the female terminal 10, and a signal socket 17. The signal socket 17 has a signal socket 12. A groove 18 is located at the center of the housing 14. The bottom of the groove 18 has three through holes: two for mounting the female terminal 10 and one for mounting the first signal socket 20.

[0038] The two female terminal mounting through holes 10 and the one signal jack mounting first through hole 20 are all stepped holes. The female terminal mounting through hole 19 has a three-layer stepped hole structure, which consists of a first-layer stepped hole 21, a second-layer stepped hole 22, and a third-layer stepped hole 23 with decreasing inner diameter from top to bottom. The signal jack mounting first through hole 20 has a two-layer stepped hole structure, which consists of a first-layer stepped hole 24 and a second-layer stepped hole 25 with decreasing inner diameter from the top to the bottom of the base plate 15.

[0039] The bottom structure of the base plate 15 is the same as that of the bottom of the groove 18. The base plate 15 is provided with three through holes in sequence: a first through hole 26 for mounting the female terminal sleeve, a second through hole 27 for mounting the female terminal sleeve, and a second through hole 28 for mounting the signal socket. The positions of the first through hole 26 for mounting the female terminal sleeve, the second through hole 27 for mounting the female terminal sleeve, and the second through hole 28 for mounting the signal socket correspond to the positions of two female terminal mounting through holes 19 and one signal socket mounting first through hole 20, respectively. Below the base plate 15, an annular protrusion 29 is integrally formed on the outer side of the first through hole 26 for mounting the female terminal sleeve, the second through hole 27 for mounting the female terminal sleeve, and the second through hole 28 for mounting the signal socket. The outer diameter of the annular protrusion 29 below the first through hole 26 and the second through hole 27 of the female terminal sleeve on the base plate 15 is larger than the inner diameter of the first layer of stepped hole 21 of the female terminal. The outer diameter of the annular protrusion 29 below the second through hole 28 of the signal socket is larger than the inner diameter of the first layer of stepped hole 24 of the signal socket.

[0040] During installation, the annular protrusions 29 below the first through hole 26 for mounting the female terminal sleeve, the second through hole 27 for mounting the female terminal sleeve, and the second through hole 28 for mounting the signal socket on the base plate 15 are respectively engaged inside the first-layer stepped holes 21 of the two female terminals and the first-layer stepped hole 24 of the one signal socket. The base plate 15 is then fixedly mounted on the bottom of the groove 18 on the outer casing 14 by means of interference fit.

[0041] The outer diameter of the female terminal sleeve 16 is larger than the inner diameter of the first through hole 26 and the second through hole 27 of the female terminal sleeve. During installation, the two female terminal sleeves 16 are fixed inside the first through hole 26 and the second through hole 27 of the female terminal sleeve by interference fit. The outer diameter of the signal socket 17 is larger than or equal to the inner diameter of the second through hole 28 of the signal socket. During installation, it is fixed inside the second through hole 28 of the signal socket by interference fit and adhesive 30.

[0042] The female terminal 10 includes a cylindrical portion 31, a stepped portion, and a bolt portion 37 integrally formed from top to bottom. The stepped portion is arranged from top to bottom as a first step 32, a second step 33, a third step 34, a fourth step 35, and a fifth step 36. The bolt portion 37 is fixedly located at the bottom center of the fifth step 36. The other end of the bolt portion 37 extends to the outside of the socket body 9 and can form an electrical connection with the vehicle power system through a wire. In the stepped portion, the outer diameter relationship is second step 33 > first step 32 > third step 34 = fifth step 36 > fourth step 35, and the outer diameter of the second step 33 is equal to the outer diameter of the cylindrical portion 31. In the second step 33 portion, a notch 38 is provided at each of its radial ends on the outer circumference of the second step 33. The outer diameter of the notch 38 is equal to the outer diameter of the first step 32.

[0043] The outer diameter of the cylindrical portion 31 of the female terminal 10 is smaller than the inner diameter of the mounting sleeve of the female terminal 10, and the outer diameter of the third step 34 is smaller than the inner diameter of the second step hole and the third step hole of the female terminal 10; a vent hole 11 is provided below the cylindrical portion 31 of the female terminal 10, penetrating the thickness direction of the cylindrical portion 31 of the female terminal 10; during installation, the female terminal 10 is inserted into the mounting sleeve of the female terminal 10, and adhesive 30 is applied to the outer wall above the vent hole 11 of the cylindrical portion 31 of the female terminal 10, and to the outer walls of the second step 33 and the fifth step 36, wherein the notch on the second step 33 is provided. Without applying adhesive 30 at 38 locations, the female terminal 10 is fixedly installed in the female terminal 10 mounting sleeve and the female terminal 10 mounting through hole. After installation, gaps exist between the outer wall below the vent hole 11 in the cylindrical part 31 of the female terminal 10 and the inner wall of the female terminal 10 mounting sleeve, between the outer wall of the first step 32 and the inner wall of the female terminal 10 mounting sleeve, between the notch 38 of the second step 33 and the inner wall of the female terminal 10 mounting sleeve, between the outer wall of the third step 34 and the inner wall of the second step hole, and between the outer wall of the fourth step 35 and the inner wall of the third step hole, forming an air bladder 39.

[0044] The male terminal 5 has the same structure as the internal structure of the cylindrical part 31 of the female terminal 10. The male terminal 5 can be fully inserted into the cylindrical part 31 of the female terminal 10 to form an electrical connection. The pin and the socket have the same structure. The pin is inserted into the socket to form an electrical connection.

[0045] When the male terminal 5 is inserted into the female terminal 10, the gas inside the cylindrical portion 31 of the female terminal 10 is discharged through the vent 11 and enters the air bladder 39. At this time, because the vent 11 is small, the gas will be discharged slowly, which can form a buffer force when the male terminal 5 is inserted, preventing the male terminal 5 from being inserted into the bottom of the female terminal 10 instantaneously, which would damage the structure of the male terminal 5 and affect the reliability of the electrical connection. After the male terminal 5 is fully inserted into the female terminal 10, a local negative pressure environment is formed between the male terminal 5 and the female terminal 10, which can firmly hold the male terminal 5 in place. Attached to the female terminal 10, the vibration during vehicle operation will not easily cause the male terminal 5 to detach from the female terminal 10, ensuring an effective connection between the male terminal 5 and the female terminal 10. When it is necessary to pull out the male terminal 5, the plug 1 is pulled out forcefully, which first creates a small gap between the male terminal 5 and the female terminal 10. The gas in the airbag 39 slowly enters the bottom of the cylinder of the female terminal 10 through the vent 11, so that the male terminal 5 can be slowly pulled out from the female terminal 10, forming a buffer effect and avoiding structural damage to the battery swapping connector caused by instantaneous pulling out.

[0046] When plug 1 is inserted into socket 2, guide post 7 can act as a guide. Guide post 7 is inserted into guide post sleeve 13 to prevent position deviation during insertion.

[0047] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the design concept of the present invention should be included within the protection scope of the present invention.
