[0037] This specific implementation is a battery replacement type electric connector for new energy electric vehicles with improved shock resistance, and its structural schematic diagram is as follows: Figure 1-10 As shown, the battery-swap battery electrical connector includes an electrical connection socket 2 and an electrical connection plug 1 that cooperates with the electrical connection socket 2. A fixing plate 4 is fixedly connected to the bottom of the electrical connection plug 1, and a mounting plate 5 is fixedly connected to the top of the electrical connection socket 2. A mounting shell 6 is sleeved on the outer side of the mounting plate 5, and a circle of mounting enclosure 7 is fixedly connected to the outer side of the mounting shell 6. Fixing holes are provided on the fixing plate 4 and the mounting enclosure 7. The fixing plate 4 is fixed to the battery-swap battery by screws passing through the fixing holes. The electrical connection plug 1 is electrically connected to the battery-swap battery through a wire, and the mounting enclosure 7 is fixed to the new energy electric vehicle by screws passing through the fixing holes. The electrical connection socket 2 is electrically connected to the electronic control system of the new energy electric vehicle through a wire.
[0038] In this embodiment, if Figure 3 , Figure 4 and Figure 8As shown, the mounting plate 5 moves and adjusts its position in the mounting shell 6, and a deflection adjustment structure 8 is provided between the mounting plate 5 and the fixing plate 4. The deflection adjustment structure 8 is used to adjust the relative plugging position of the electrical connection socket 2 and the electrical connection plug 1. The deflection adjustment structure 8 includes a first embedded sleeve 82 and a second embedded sleeve 84 fixedly connected to the bottom of the mounting plate 5, and a first embedded seat 81 and a second embedded seat 83 fixedly connected to the top of the fixing plate 4. The first embedded seat 81 corresponds to the first embedded sleeve 82, and the second embedded seat 83 corresponds to the second embedded sleeve 84. The first embedded sleeve 82 is fixedly connected to the bottom of the mounting plate 5, and the second embedded seat 83 corresponds to the second embedded sleeve 84. 2 and the second embedded sleeve 84 are designed with an open end close to the first embedded seat 81 and the second embedded seat 83. When the electrical connection plug 1 is plugged into the electrical connection socket 2, the first embedded seat 81 is inserted into the first embedded sleeve 82 to adjust the longitudinal position of the electrical connection socket 2, and the second embedded seat 83 is inserted into the second embedded sleeve 84 to adjust the lateral position of the electrical connection socket 2. The offset adjustment structure 8 is used to adjust the lateral and longitudinal positions of the electrical connection socket 2 to prevent the problems of offset and poor contact when the electrical connection plug 1 is plugged into the electrical connection socket 2.
[0039] Specifically, both sides of the openings of the first embedded sleeve 82 and the second embedded sleeve 84 along the length direction are provided with flared openings that expand outward, and both sides of the insertion ends of the first embedded seat 81 and the second embedded seat 83 are provided with inwardly contracted openings. The contracted openings of the first embedded seat 81 and the second embedded seat 83 are adapted to the flared inclinations of the first embedded sleeve 82 and the second embedded sleeve 84. When there is misalignment during the plugging process of the electrical connection plug 1 and the electrical connection socket 2, the electrical connection plug 1 moves close to the position of the electrical connection socket 2, so that the insertion end of the first embedded seat 81 is inserted into the first embedded sleeve 82, and the contracted opening of the first embedded seat 81 contacts the inner wall of the flared opening of the first embedded sleeve 82. As the first embedded seat 81 continues to penetrate deeper into the first embedded sleeve 82, the first embedded seat 81 pushes the first embedded sleeve 82 to move longitudinally until the first embedded seat 81 is inserted into the first embedded socket. When the second embedded sleeve 84 is inserted into the second embedded sleeve 84, the second embedded sleeve 84 is adjusted to the right position longitudinally, and the first embedded sleeve 82 drives the mounting plate 5 to adjust its position longitudinally, so that the longitudinal position of the electrical connection socket 2 is adjusted to the right position; at the same time, the insertion end of the second embedded seat 83 is inserted into the second embedded sleeve 84, and the shrinkage of the second embedded seat 83 contacts the expanded inner wall of the second embedded sleeve 84. As the second embedded seat 83 continues to go deeper into the second embedded sleeve 84, the second embedded seat 83 pushes the second embedded sleeve 84 to move laterally until the second embedded seat 83 is inserted into the second embedded sleeve 84. The second embedded sleeve 84 is adjusted to the right position laterally, and the second embedded sleeve 84 drives the mounting plate 5 to adjust its position laterally, so as to adjust the horizontal position of the electrical connection socket 2 to the right position, so as to ensure that the electrical connection plug 1 and the electrical connection socket 2 are accurately aligned when plugged in, avoid poor contact, the possibility of damage, and improve the service life.
[0040] The length of the first embedded seat 81 is the same as the length inside the first embedded sleeve 82, and is used to limit the longitudinal position of the first embedded sleeve 82 when the first embedded seat 81 is inserted into the first embedded sleeve 82. The thickness of the first embedded seat 81 is less than the width inside the first embedded sleeve 82, and the width inside the first embedded sleeve 82 is greater than twice the thickness of the first embedded seat 81. When the mounting plate is adjusted laterally, the first embedded seat 81 can move laterally in the first embedded sleeve 82 to provide space for the lateral movement of the mounting plate 5. The length of the second embedded seat 83 is the same as the length inside the second embedded sleeve 84. When the second embedded seat 83 is inserted into the second embedded sleeve 84, the lateral position of the second embedded seat 83 is limited. The thickness of the second embedded seat 83 is less than the width inside the second embedded sleeve 84, and the width inside the second embedded sleeve 84 is greater than twice the thickness of the second embedded seat 83. When the mounting plate is adjusted laterally, the second embedded seat 83 can move longitudinally in the second embedded sleeve 84 to provide space for the longitudinal movement of the mounting plate 5.
[0041] The second ball 812 is rollingly embedded and installed on the constricted openings on both sides of the first embedded seat 81 and the second embedded seat 83 and on the side walls. The setting of the second ball 812 can reduce the friction force when the first embedded seat 81 and the second embedded seat 83 move in the first embedded sleeve 82 and the second embedded sleeve 84, which helps to push the position adjustment of the first embedded sleeve 82 and the second embedded sleeve 84.
[0042] In the present embodiment, it should be noted that the height of the top of the first embedded seat 81 and the second embedded seat 83 is the same as the height of the top of the electrical connection plug 1, and the height of the flared openings on the first embedded sleeve 82 and the second embedded sleeve 84 is lower than the height of the bottom surface of the electrical connection socket 2, so that when the first embedded seat 81 is inserted into the flared opening of the first embedded sleeve 82 to adjust the position of the first embedded sleeve 82, the electrical connection plug 1 and the electrical connection socket 2 are not yet plugged in. When the first embedded seat 81 is inserted into the first embedded sleeve 82 for a certain distance, the distance can be set according to design requirements. In the present embodiment, it is designed to be 1-3 cm, and the electrical connection plug 1 and the electrical connection socket 2 are plugged in. Similarly, the second embedded seat 83 and the second embedded sleeve 84 have the same principle to ensure that the electrical connection socket 2 is adjusted into place before being plugged in with the electrical connection plug 1 to ensure the accuracy of alignment.
[0043] In some embodiments of the present invention, multiple groups of first embedded seats 81, first embedded sleeves 82, second embedded seats 83 and second embedded sleeves 84 may be arranged in alignment. Specifically, a pair of first embedded seats 81 are symmetrically arranged on the left and right sides of the electrical connection plug 1, a pair of second embedded seats 83 are symmetrically arranged on the front and back sides of the electrical connection plug 1, a pair of first embedded sleeves 82 are symmetrically arranged on the left and right sides of the electrical connection socket 2, and a pair of second embedded sleeves 84 are symmetrically arranged on the left and right sides of the electrical connection socket 2. They are arranged in a circle around the outer sides of the electrical connection plug 1 and the electrical connection socket 2 to improve the position adjustment effect of the electrical connection socket 2.
[0044] In this embodiment, if Figure 5 As shown, fixing columns are fixedly connected at the four corners inside the mounting shell 6, and adjusting tension springs 10 are installed between the mounting plate 5 and the adjacent fixing columns. Four adjusting tension springs 10 are provided, which are distributed at the four corners of the mounting plate 5 and the mounting shell 6. The four adjusting tension springs 10 evenly distribute the tension on the mounting plate 5, so that when the electrical connection plug 1 is plugged into the electrical connection socket 2, when the position of the electrical connection socket 2 is adjusted, the mounting plate 5 can be offset in any direction. When the electrical connection plug 1 is separated from the electrical connection socket 2, under the action of the adjusting tension springs 10, the mounting plate 5 and the electrical connection socket 2 are automatically reset to the middle position of the mounting shell 6, so as to facilitate the alignment and plugging of the electrical connection plug 1 and the electrical connection socket 2 when the battery is replaced next time.
[0045] In this embodiment, if Figure 5 As shown, first balls 51 are rollingly embedded at the edges of both sides of the mounting plate 5. The first balls 51 are arranged around the mounting plate 5 in a circle. The first balls 51 are in contact with the inner wall of the mounting shell 6. The friction of the mounting plate 5 moving in the mounting shell 6 is reduced by the arrangement of the first balls 51, which helps the mounting plate 5 to adjust its position more smoothly.
[0046] In this embodiment, if Figure 4 and Fig.10 As shown, the battery-replacement connector also includes a locking mechanism 9, which is used to lock and fix the first embedded seat 81 and the first embedded sleeve 82, and the second embedded seat 83 and the second embedded sleeve 84. After the electrical connection plug 1 and the electrical connection socket 2 are plugged in, the locking mechanism 9 locks and fixes the first embedded seat 81 and the first embedded sleeve 82, and locks and fixes the second embedded seat 83 and the second embedded sleeve 84, thereby improving the stability of the electrical connection plug 1 and the electrical connection socket 2 after plugging in, avoiding the electrical connection plug 1 and the electrical connection socket 2 from becoming loose or disconnected when the electric vehicle is vibrating during driving, and improving its anti-seismic performance.
[0047] Specifically, the locking mechanism 9 includes a movable plate 91 arranged below the mounting plate 5, and the movable plate 91 is arranged on the outer sides of the electrical connection socket 2 and the first embedded sleeve 82 and the second embedded sleeve 84. A driving member 92 is fixedly connected to the top of the mounting plate 5. In the present embodiment, the driving member 92 is an electric push rod, and the output end of the driving member 92 passes through the mounting plate 5 and is fixedly connected to the movable plate 91. The driving member 92 is used to drive the movable plate 91 to move longitudinally. The outer sides of the first embedded sleeve 82 and the second embedded sleeve 84 are both fixedly connected to a guide sleeve 93, and a plug rod 94 is slidably installed in the guide sleeve 93. The plug rod 94 moves axially along the guide sleeve 93. A connecting seat 96 is fixedly connected to the corresponding plug rod 94 on the movable plate 91, and a linkage rod 95 is movably hinged between one end of the plug rod 94 and the corresponding connecting seat 96. A second plug hole 821 coaxially arranged with the guide sleeve 93 is provided on the first embedded sleeve 82 and the second embedded sleeve 84. The second embedded seat 83 is provided with a first plug hole 811. When the first embedded seat 81 is inserted into the first embedded sleeve 82 and is in place, the first plug hole 811 and the second plug hole 821 are coaxially arranged. The second plug hole 821 and the first plug hole 811 are used for the linkage rod 95 to pass through. After the electrical connection plug 1 and the electrical connection socket 2 are plugged into place, the first embedded seat 81 is plugged into place in the first embedded sleeve 82, and the second embedded seat 83 is plugged into place in the second embedded sleeve 84, so that the first plug hole 811 and the second plug hole 821 are coaxially aligned, and then the driving member 92 drives the movable plate 91 to move longitudinally, and the linkage rod 95 drives the plug rod 94 to move axially in the guide sleeve 93, so that the plug rod 94 passes through the second plug hole 821 and the first plug hole 811, and the first embedded seat 81 and the first embedded sleeve 82 are locked and fixed, and the second embedded seat 83 and the second embedded sleeve 84 are locked and fixed, thereby improving the plug-in stability of the electrical connection plug 1 and the electrical connection socket 2.
[0048] In order to improve the stability of the movable plate 91 during movement, a support seat 98 is provided on the outer side of the movable plate 91, and the support seat 98 is fixedly connected to the mounting plate 5. A guide rod 97 is fixedly connected between one end of the support seat 98 and the mounting plate 5. The guide rod 97 is arranged along the moving direction of the movable plate 91. A guide hole is opened at a position corresponding to the guide rod 97 on the movable plate 91. The movable plate 91 is slidably connected to the guide rod 97 through the guide hole. Four groups of support seats 98 and guide rods 97 are arranged, which are distributed at the four corners of the movable plate 91. During the movement of the movable plate 91, the movable plate 91 slides on the guide rod 97 to ensure the stability and smoothness of the movable plate 91 during movement.

When the electrical connection plug 1 is plugged in and out of the electrical connection socket 2, the abutment plate 334 abuts against the pressing seat 31, and when the electrical connection plug 1 and the electrical connection socket 2 are plugged in, the abutment plate 334 abuts against the pressing seat 31. When the socket 2 is plugged in, the pressure seat 31 contacts the abutment plate 334 and pushes the abutment plate 334 toward the fixed enclosure 32.

During the plugging process, the insertion end of the first embedded seat 81 is inserted into the first embedded sleeve 82, and the shrinkage of the first embedded seat 81 contacts the expanded inner wall of the first embedded sleeve 82. As the first embedded seat 81 continues to penetrate deeper into the first embedded sleeve 82, the first embedded seat 81 pushes the first embedded sleeve 82 to move longitudinally until the first embedded seat 81 is inserted into the first embedded sleeve 82. The first embedded sleeve 82 is longitudinally adjusted into place, and the first embedded sleeve 8 2 drives the mounting plate 5 and adjusts longitudinally into place.

Under the action of the buffer spring 335, the impact force is mitigated and reduced. At the same time, the lifting rod 332 drives the piston 333 to move in the sleeve 331, and the gas in the sleeve 331 is transported to the sealing airbag 35 through the vent pipe 36, and the sealing airbag 35 is inflated, so that the sealing airbag 35 is filled in the sealing groove 311 of the pressing seat 31, effectively closing the gap between the electrical connection plug 1 and the electrical connection socket 2, greatly improving the sealing between the electrical connection plug 1 and the electrical connection socket 2, and preventing dust and other impurities from polluting the electrical connection plug 1 and the electrical connection socket 2;
[0053] After the electrical connection plug 1 and the electrical connection socket 2 are connected, the driving member 92 drives the movable plate 91 to move longitudinally, and the linkage rod 95 drives the insertion rod 94 to move axially in the guide sleeve 93, so that the insertion rod 94 passes through the second insertion hole 821 and the first insertion hole 811, locks and fixes the first embedding seat 81 and the first embedding sleeve 82, and locks and fixes the second embedding seat 83 and the second embedding sleeve 84, thereby improving the plug-in stability of the electrical connection plug 1 and the electrical connection socket 2, avoiding the electrical connection plug 1 and the electrical connection socket 2 from being loosened or disconnected when the electric vehicle is vibrating during driving, and improving its anti-seismic performance.
