[0035] First Embodiment

[0036] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 , an embodiment of the present invention provides an automobile (not shown in the figure) for transportation. The grounding device 100 therein is convenient to assemble, has a large conduction contact surface, is stable and reliable, consumes less energy during the conduction process, avoids interfering with the control signal, has strong practicability and high safety. The automobile includes electrical appliances (not shown in the figure), a grounding device 100, and a vehicle frame (not shown in the figure). The electrical appliances and the grounding device 100 are both installed on the vehicle frame. The ground wire of the electrical appliances is connected to the grounding device 100, and the grounding device 100 is conducted to the ground through the vehicle frame to realize the grounding of the ground wire of the electrical appliances. In this embodiment, the number of electrical appliances is multiple, and the ground wires of the multiple electrical appliances are all connected to the grounding device 100. The grounding device 100 can make the ground wires of the multiple electrical appliances be grounded simultaneously, so as to improve the assembly efficiency, reduce the material cost, and ensure the high-precision control of the electrical appliances.

[0037] The grounding device 100 includes a grounding main body 110, a terminal 120, a wire 130, a grounding fixing part 140, a grounding pipe 150, a support part 160, and a dust cover 170. The ground wire of the electrical appliances is connected to the wire 130, and the wire 130 is connected to the terminal 120 to conduct the ground wire of the electrical appliances to the terminal 120. The terminal 120 is connected to the grounding main body 110 and is arranged in contact with the grounding main body 110 to conduct the wire 130 to the grounding main body 110 and improve the reliability of the connection. The grounding main body 110 cooperates with the grounding fixing part 140, the grounding fixing part 140 is fixedly connected to the grounding pipe 150, and the grounding pipe 150 is fixedly connected to the vehicle frame to realize the conduction of the ground wire of the electrical appliances to the vehicle frame.

[0038] In this embodiment, the number of electrical appliances is four, and the number of wires 130 and terminal blocks 120 is also four. The ground wire of each electrical appliance is connected to a terminal block 120 through a wire 130, and the four terminal blocks 120 are all connected to the grounding body 110 to achieve four-point centralized grounding of the four electrical appliances. However, this is not limited thereto. In other embodiments, the number of electrical appliances can be one, six, or eight, and the number of electrical appliances is not specifically limited. The grounding body 110 can be connected to the ground wires of multiple electrical appliances to achieve multi-point centralized grounding of multiple electrical appliances.

[0039] It should be noted that the grounding body 110 is provided with a mating groove 111, and the grounding fixing member 140 is provided with a boss 141. The boss 141 extends into the mating groove 111 and is in contact with the inner wall of the mating groove 111, so that the wire 130 can be electrically connected to the grounding pipe 150. During this process, due to the cooperation between the boss 141 and the mating groove 111, the contact area between the grounding body 110 and the grounding fixing member 140 is increased, so the conduction contact surface is increased, the conduction reliability is improved, and the energy consumption during the conduction process is reduced, avoiding interference with the control signal.

[0040] In this embodiment, the boss 141 and the mating groove 111 are in transitional fit. The boss 141 is selectively inserted into the mating groove 111 and is in contact with the inner wall of the mating groove 111, so as to realize the detachable connection between the grounding body 110 and the grounding fixing member 140, which is convenient for installation and maintenance and easy to assemble. Specifically, the boss 141 is in the shape of a rectangular body, and the mating groove 111 is a through groove, which is convenient for the boss 141 to be inserted into or pulled out of the mating groove 111.

[0041] In this embodiment, a first through hole 112 is formed in the bottom wall of the mating groove 111, and the first through hole 112 is communicated with the mating groove 111. The boss 141 is provided with a threaded hole 142. The first through hole 112 is used for the screw 180 to pass through. The screw 180 passes through the first through hole 112 and cooperates with the threaded hole 142 to fix the relative positions of the grounding body 110 and the grounding fixing member 140, preventing the grounding body 110 and the grounding fixing member 140 from separating.

[0042] It should be noted that the height of the boss 141 is less than or equal to the depth of the mating groove 111. When the boss 141 and the mating groove 111 are in place, the grounding fixing member 140 abuts against the grounding body 110, so that the grounding body 110 and the grounding fixing member 140 are closely fitted, and the contact area between the grounding body 110 and the grounding fixing member 140 is increased. In this embodiment, the height of the boss 141 is equal to the depth of the mating groove 111. When the boss 141 and the mating groove 111 are in place, the top surface of the boss 141 is in contact with the bottom wall of the mating groove 111, further increasing the contact area between the grounding body 110 and the grounding fixing member 140.

[0043] It should be noted that the grounding body 110 is further provided with a second through hole 113, and the wiring terminal 120 is provided with a third through hole 121. The position of the second through hole 113 corresponds to the position of the third through hole 121. Both the second through hole 113 and the third through hole 121 are used for the first bolt 190 to pass through. The first bolt 190 cooperates with the first nut 200 to achieve the detachable connection between the grounding body 110 and the wiring terminal 120, which is convenient for installation and maintenance. During the installation of the wiring terminal 120, first align the second through hole 113 with the third through hole 121, and then pass the first bolt 190 through the second through hole 113 and the third through hole 121 in sequence and tighten it relative to the first nut 200 to fix the relative positions of the grounding body 110 and the wiring terminal 120.

[0044] In this embodiment, the number of the second through holes 113 on the grounding body 110 is two, and the two second through holes 113 are respectively arranged on both sides of the fitting groove 111. The number of the wiring terminals 120 and the wires 130 is four each. Each wire 130 is connected to one wiring terminal 120. Among them, two wiring terminals 120 are respectively attached to both sides of one second through hole 113, and the other two wiring terminals 120 are respectively attached to both sides of the other second through hole 113. The first bolt 190 passes through one third through hole 121, the second through hole 113 and the other third through hole 121 in sequence and cooperates with the first nut 200 to fix the relative positions of the two wiring terminals 120 and the grounding body 110 at the same time. Specifically, the number of the first bolts 190 and the first nuts 200 is two each, and they respectively correspond to the two second through holes 113 to fix the positions of the four wiring terminals 120.

[0045] It should be noted that the support member 160 is detachably connected to the grounding body 110 and abuts against the wiring terminal 120 to fix the relative positions of the wiring terminal 120 and the grounding body 110, thereby preventing the wiring terminal 120 from loosening under the long-term action of gravity and the bending stress between the wire 130 and the wiring terminal 120, and improving the connection stability of the wiring terminal 120.

[0046] It should be noted that the support member 160 includes a bracket 161 and a guiding spacer 162. The grounding body 110 is further provided with a fourth through hole 114 for the second bolt 210 to pass through. The second bolt 210 sequentially passes through the guiding spacer 162, the bracket 161 and the fourth through hole 114, and cooperates with the second nut 220 to realize the detachable connection between the grounding body 110 and the bracket 161, which is convenient for installation and maintenance. The bracket 161 abuts against the terminal 120 to lift the terminal 120 and prevent the terminal 120 from loosening relative to the grounding body 110. Specifically, the second bolt 210 can be tightened or loosened relative to the second nut 220 to adjust the distance between the bracket 161 and the grounding body 110 so that it can adapt to terminals 120 of different sizes.

[0047] In this embodiment, the bracket 161 is in a U-shape. The bracket 161 includes a connecting portion 163 and two lifting portions 164. One lifting portion 164 is connected to the other lifting portion 164 through the connecting portion 163. The lifting portion 164 is arc-shaped and matches the shape of the terminal 120. The lifting portion 164 cooperates with the terminal 120, and the lifting portion 164 can limit and support the terminal 120 to prevent the terminal 120 from loosening. The connecting portion 163 is for the second bolt 210 to pass through. The second bolt 210 sequentially passes through the guiding spacer 162, the connecting portion 163 and the fourth through hole 114, and cooperates with the second nut 220. Specifically, the number of the bracket 161, the guiding spacer 162, the second bolt 210 and the second nut 220 is two, so as to limit and support four terminals 120 simultaneously, which is stable and reliable.

[0048] It should be noted that the dust cover 170 is covered on the grounding body 110. The dust cover 170 is used to block external dust and sundries to prevent them from adhering to the grounding body 110 and the grounding fixture 140, avoid corrosion of the grounding body 110 and the grounding fixture 140, and extend the service life of the grounding device 100. Specifically, the dust cover 170 is provided with a relief opening 171, and the terminal 120 is arranged in the relief opening 171 to facilitate the external connection of the terminal 120 to the wire 130, which is convenient for installation and maintenance.

[0049] In this embodiment, the dust cover 170 is further provided with two first openings 172, which correspond to the two fourth through holes 114 one by one. The position of the first opening 172 corresponds to the position of the fourth through hole 114 on the grounding body 110. The second bolt 210 sequentially passes through the guiding spacer 162, the bracket 161, the fourth through hole 114 and the first opening 172, and cooperates with the second nut 220 to realize the detachable connection between the grounding body 110 and the dust cover 170, which is convenient for installation and maintenance.

[0050] The grounding device 100 provided by the embodiment of the present invention has a wire 130 connected to a terminal 120.
