[0035] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments, but the implementation scope of the present invention is not limited thereto.

[0036] like Figures 1 to 13 As shown, a copper busbar connector for new energy vehicles described in this embodiment includes a housing 1, a connection terminal 2 inserted through the housing 1, and a heat dissipation component installed in the housing 1; the housing 1 is provided with a vent 11; the housing 1 is provided with a plurality of connection terminals 2, and the plurality of connection terminals 2 are respectively a U-phase terminal, a V-phase terminal, and a W-phase terminal to meet power demand;

[0037] The heat dissipation assembly includes a heat dissipation seat 31, a driving slider 32 slidably mounted on the heat dissipation seat 31, a thermal spring 33 mounted on the heat dissipation seat 31, a first heat dissipation plate 34 and a plurality of second heat dissipation plates 35 rotatably mounted in the vent 11; the heat dissipation seat 31 is preferably made of a material with good thermal conductivity and insulation, such as alumina ceramic, one end of the thermal spring 33 is connected to the heat dissipation seat 31, and the other end of the thermal spring 33 is connected to the driving slider 32; the first heat dissipation plate 34 and the second heat dissipation plate 35 both have a rotating shaft, and the rotating shafts are connected by a transmission assembly, the rotating shaft of the first heat dissipation plate 34 is provided with a first driving structure, and a tension spring 36 is provided between the first driving structure and the heat dissipation seat 31; the driving slider 32 is provided with a second driving structure for cooperating with the first driving structure, so that the first heat dissipation plate 34 and the second heat dissipation plate 35 close the vent 11 in the first state, and open the vent 11 in the second state.

[0038] Specifically, when the copper busbar connector for new energy vehicles of this embodiment is within the normal operating temperature range, the thermal spring 33 is in a natural state, and the first heat sink 34 and the second heat sink 35 close the vent 11 in the first state;

[0039] After the temperature is higher than the normal operating temperature, the thermal spring 33 is heated and elongated, pushing the driving slider 32 to slide relative to the heat sink 31. When the second driving structure of the driving slider 32 cooperates with the first driving structure of the first heat sink 34, the driving slider applies a thrust to the first driving structure through the second driving structure. At this time, the tension applied by the tension spring 36 to the first driving structure is a resistance, so that the first driving structure overcomes the tension of the tension spring 36 to drive the first heat sink 34 to rotate, so that the first heat sink 34 switches from the first state to the second state. At the same time, the first heat sink 34 drives each second heat sink 35 to rotate synchronously through the transmission assembly until the tension applied by the tension spring 36 to the first driving structure is converted into a driving force. Under the joint action of the driving slider 32 and the tension spring 36, the first heat sink 34 quickly rotates to the second state. At this time, the first heat sink 34 and the second heat sink 35 are both in the second state, thereby opening the vent 11 and increasing the air flow in the shell 1, so that the heat in the shell 1 is dissipated to the external environment through the vent 11, thereby improving the heat dissipation efficiency and effectively reducing the working temperature of the connector.

[0040] In this embodiment, a heat dissipation component is arranged in the shell 1, and a first heat sink 34 and a second heat sink 35 with a first state and a second state are arranged in the vent 11, so that when the working temperature is normal, the first heat sink 34 and the second heat sink 35 can close the vent 11 in the first state to prevent foreign matter or liquid from entering the interior of the connector; when the temperature inside the connector is higher than its working temperature, the first heat sink 34 and the second heat sink 35 can automatically open the vent 11 in the second state under the drive of the thermistor spring 33, thereby facilitating the dissipation of heat inside the connector and effectively cooling the interior of the connector; such a configuration is conducive to extending the service life of the connector.

[0041] The copper busbar connector for new energy vehicles described in this embodiment, in some embodiments, Figure 3 and Fig.13 As shown, the second driving structure includes a first pushing boss 321 and a second pushing boss 322 which are spaced apart on the driving slider 32; and the second pushing boss 322 is arranged close to the middle of the driving slider 32;

[0042] like Figure 6 , Figure 7 and Fig.10 As shown, the first driving structure includes a first swing plate 341 arranged on the rotating shaft of the first heat dissipation plate 34, a first pin shaft 342 and a second pin shaft 343 arranged on the first swing plate 341; the first pin shaft 342 is used to cooperate with the first pushing boss 321, the first pin shaft 342 is arranged on the center line of the first swing plate 341 and is located on one end of the first swing plate 341 close to the driving slider 32; the second pin shaft 343 is used to cooperate with the second pushing boss 322, the second pin shaft 343 is arranged deviating from the center line of the first swing plate 341 and close to the middle of the first swing plate 341; the second pin shaft 343 is connected to one end of the tension spring 36.

[0043] Specifically, within the normal operating temperature range, since the thermal spring 33 is in a natural state, the first push boss 321 is not in contact with the first pin shaft 342, and the first swing plate 341 swings toward the direction of the driving slider 32 under the tension of the tension spring 36. The first swing plate 341 drives the first heat sink 34 to rotate through the rotating shaft, so that the first heat sink 34 is in the first state, and the first heat sink 34 synchronously drives each second heat sink 35 to be in the first state through the transmission assembly. Figure 4 and Figure 6 As shown, the vent 11 is thereby closed;

[0044] After the temperature is higher than the normal operating temperature, the temperature of the thermal spring 33 exceeds its deformation temperature threshold, which is the starting temperature at which the thermal spring 33 deforms. At this time, the thermal spring 33 stretches, pushing the driving slider 32 to slide in the direction of the first driving structure. When the first pushing boss 321 contacts the first pin shaft 342, the first pushing boss 321 pushes the first swing plate 341 to swing through the first pin shaft 342. At this time, due to the eccentric setting of the second pin shaft 343 and the second pushing boss 322 close to the middle of the driving slider 32, the first swing plate 341 is pushed by the first pushing boss 321 to swing. The second pushing boss 322 is not in contact with the second pin shaft 343. The first swing plate 341 overcomes the pulling force of the tension spring 36 under the push of the driving slider 32 and swings toward the moving direction of the driving slider 32, thereby driving the first heat sink 34 to rotate. After the first swing plate 341 passes the center position, the center position is the pulling direction of the tension spring 36 located on the center line of the first swing plate 341. The first swing plate 341 swings rapidly under the combined action of the thrust of the driving slider 32 and the tension of the tension spring 36, so that the first heat sink 34 rotates to the second state, such as Figure 5 and Figure 7 As shown, the vent 11 is automatically opened to ventilate and dissipate heat inside the connector;

[0045] When the temperature of the thermistor spring 33 recovers to below the deformation temperature threshold, the thermistor spring 33 recovers its deformation, driving the driving slider 32 to reset. During the resetting process of the driving slider 32, the second pushing boss 322 will contact the second pin shaft 343, so that the first swing plate 341 overcomes the pulling force of the tension spring 36 under the thrust of the driving slider 32 and swings toward the resetting direction of the driving slider 32 until the first heat sink 34 switches from the second state to the first state, thereby automatically closing the vent 11.

[0046] like Figure 3 , Figure 6 and Figure 7 As shown in the copper busbar connector for new energy vehicles described in this embodiment, in some embodiments, a limiting seat 37 is provided on the heat sink 31, and the rotating shaft of the first heat sink 34 rotates and penetrates the limiting seat 37, and a limiting arc groove 371 is provided on the limiting seat 37; a limiting pin 344 is provided on the side of the first swing plate 341 facing the limiting seat 37, and the limiting pin 344 is movably embedded in the limiting arc groove 371. In this embodiment, the swing amplitude of the first swing plate 341 is limited by providing the limiting arc groove 371 and the limiting pin 344, and at the same time, it can cooperate with the tension spring 36 to keep the first heat sink 34 in the first state or the second state.

[0047] like Figure 3 , Figure 6 , Figure 7 , Fig.10 and Fig.11As shown, in the copper busbar connector for new energy vehicles described in this embodiment, in some embodiments, the transmission assembly includes a linkage rod 38 slidably arranged on the heat sink 31, a second swing plate 351 arranged on the rotating shaft of the second heat sink 35, and a first transmission pin 345 arranged on the end of the first swing plate 341 away from the driving slider 32; one end of the second swing plate 351 is connected to the rotating shaft of the second heat sink 35, and the other end of the second swing plate 351 is provided with a second transmission pin 352; the linkage rod 38 is penetrated by a transmission hole 381 along its length direction; the first transmission pin 345 is hinged to the linkage rod 38, and the second transmission pin 352 is movably embedded in the transmission hole 381.

[0048] Specifically, when the first heat sink 34 rotates, the first transmission pin 345 on the first swing plate 341 drives the linkage rod 38 to move synchronously. During the movement of the linkage rod 38, the transmission hole 381 and the second transmission pin 352 cooperate synchronously to drive each second swing plate 351 to swing. Each second swing plate 351 drives its corresponding second heat sink 35 to rotate synchronously, thereby realizing synchronous transmission between the first heat sink 34 and the second heat sink 35.

[0049] like Figure 1 , Figures 3 to 8 , Fig.12 As shown, in the copper busbar connector for new energy vehicles described in this embodiment, in some embodiments, a scissor-type linkage mechanism 4 is provided on one side of the heat sink 31, and the rotating shaft of the first heat sink 34 and the rotating shaft of the second heat sink 35 are respectively rotatably connected at the hinge point of the scissor-type linkage mechanism 4; a color standard plate 5 is provided at one end of the housing 1 near the first heat sink 34 at the vent 11, and an adjustment component is provided at one end of the heat sink 31 near the first heat sink 34; a moving block 7 is hinged at one end of the scissor-type linkage mechanism 4, and the moving block 7 is slidably connected to the heat sink 31, and the other end of the scissor-type linkage mechanism 4 is hinged on the heat sink 31 and connected to the adjustment component;

[0050] The adjusting assembly can, under the drive of the driving slider 32 , enable the scissor-type linkage mechanism 4 to synchronously drive the first heat sink 34 and the second heat sink 35 to move toward the color standard plate 5 in the second state during the contraction movement until the first heat sink 34 contacts the color standard plate 5 .

[0051] Specifically, after the first heat sink 34 and the second heat sink 35 are in the second state to open the vent 11, when the temperature inside the connector continues to rise to the overheated state, the thermal spring 33 continues to push the driving slider 32 to slide until the driving slider 32 drives the adjusting component to work, and the adjusting component drives the scissor-type linkage mechanism 4 to perform a contraction movement, and the moving block 7 slides relative to the heat sink 31 toward the color standard plate 5. Since the first heat sink 34 and the second heat sink 35 are hinged at the hinge point of the scissor-type linkage mechanism 4, the scissor-type linkage mechanism 4 synchronously drives the first heat sink 34 and the second heat sink 35 to move toward the color standard plate 5 until the first heat sink 34 contacts the color standard plate 5, so that the surface of the first heat sink 34 contacting the color standard plate 5 is colored. Fig.12 As shown;

[0052] After the temperature of the connector is lowered after the work is finished, the thermal spring 33 recovers its deformation, driving the driving slider 32 to reset, and the driving slider 32 pushes the first heat sink 34 to switch from the second state to the first state, and the first heat sink 34 simultaneously drives each second heat sink 35 to switch from the second state to the first state, and the adjustment component drives the scissor-type linkage mechanism 4 to stretch, and the scissor-type linkage mechanism 4 drives the first heat sink 34 and the second heat sink 35 to move away from the color standard plate 5, thereby closing the vent 11. At this time, the surface of the first heat sink 34 with the color printed on it faces outward, so that the user can observe the color of the surface of the first heat sink 34 through the vent 11, thereby serving as a warning that "the connector has worked in an overheated state", so that the user can promptly check whether the internal structure or parts of the connector are faulty to avoid causing more serious damage.

[0053] like Figures 3 to 9 , Fig.14 As shown, in the copper busbar connector for new energy vehicles described in this embodiment, in some embodiments, the adjustment component includes a roller 61, an adjustment rod 62, a coil spring 63 and a driven rod 64, one end of the adjustment rod 62 is hinged on the heat sink 31, the other end of the adjustment rod 62 is hinged to the other end of the scissor-type linkage mechanism 4, the journal of the roller 61 is fixedly sleeved with one end of the adjustment rod 62, the coil spring 63 is arranged in the roller 61, one end of the coil spring 63 is connected to the heat sink 31, the other end of the coil spring 63 is connected to the roller 61, one end of the driven rod 64 is hinged on the end face of the roller 61, and the other end of the driven rod 64 extends to correspond to the position of the driving slider 32.

[0054] When the thermal spring 33 continues to push the driving slider 32 to slide until it contacts the driven rod 64, the driving slider 32 applies a thrust to the driven rod 64, so that the driven rod 64 drives the roller 61 to rotate, so that the coil spring 63 stores energy. During the rotation of the roller 61, the adjusting rod 62 is synchronously driven to swing. Since the adjusting rod 62 is hinged to the scissor-type linkage mechanism 4, the scissor-type linkage mechanism 4 is driven to perform a contraction movement.

[0055] When the thermal spring 33 drives the driving slider 32 to reset, the driving slider 32 releases the thrust on the driven rod 64. At this time, the coil spring 63 releases the stored energy, and the coil spring 63 drives the roller 61 to rotate in the opposite direction. The roller 61 drives the adjusting rod 62 to swing in the opposite direction, so that the adjusting rod 62 drives the scissor-type linkage mechanism 4 to extend.

[0056] like Fig.12 and Fig.14 As shown, in the copper busbar connector for new energy vehicles described in this embodiment, in some embodiments, a contact pin 641 is provided at the other end of the driven rod 64, a sliding hole is provided at the other side of the heat sink 31, and a sliding pin 323 is convexly provided on the driving slider 32, and the sliding pin 323 and the contact pin 641 are respectively movably embedded in the sliding hole. In this embodiment, by providing a sliding hole, the driving slider 32 is slidably connected to the heat sink 31 through the sliding pin 323 and the sliding hole, and a contact pin 641 movably embedded in the sliding hole is provided on the driven rod 64, so that the driving slider 32 slides relatively under the push of the thermal spring 33, and a thrust is reliably applied to the driven rod 64 through the contact pin 641, so as to drive the scissor-type connecting rod mechanism 4 to perform a contraction movement.

[0057] like Figure 1 , Figures 3 to 8 , Fig.12 As shown, in the copper bar connector for new energy vehicles described in this embodiment, in some embodiments, a connecting rod 8 is provided at the hinge position where the scissor-type linkage mechanism 4 is hinged to the first heat sink 34, and the other end of the tension spring 36 is connected to one end of the connecting rod 8. In this embodiment, the connecting rod 8 is provided to facilitate the installation of the tension spring 36, and the connecting rod 8 is provided at the hinge position where the scissor-type linkage mechanism 4 is hinged to the first heat sink 34, so that when the scissor-type linkage mechanism 4 drives the first heat sink 34 to move, the connecting rod 8 can be driven by the scissor-type linkage mechanism 4 to deflect, so that the first heat sink 34 can be reliably maintained in the second state for rubbing and coloring.

[0058] like Figure 1 As shown, in the copper busbar connector for new energy vehicles described in this embodiment, in some embodiments, an insulating heat conductive sheet 39 is further provided in the housing 1, and the insulating heat conductive sheet 39 is preferably made of alumina ceramic material, one side of the insulating heat conductive sheet 39 is in contact with the connecting terminal 2, and the other side of the insulating heat conductive sheet 39 is connected to the heat sink 31.
