[0028] Please refer to Figures 1 to 7, the static conductive rubber trailing device for vehicles provided by the present utility model will be described hereinafter. The static conductive rubber trailing device for vehicles includes a rubber belt body 1 and a connecting buckle 2. The connecting buckle 2 is used to connect the rubber belt body 1 and the vehicle body. The rubber belt body 1 includes a first belt body 11 and a second belt body 12. A first connecting portion 111 is provided at the lower end of the first belt body 11, and a second connecting portion 121 corresponding to the first connecting portion 111 is provided at the upper end of the second belt body 12. The lower end of the second belt body 12 is used to contact the ground. The first connecting portion 111 and the second connecting portion 121 are connected by a connecting box 4. The connecting box 4 is sleeved on the outer periphery of the first connecting portion 111 and the second connecting portion 121. The upper part of the first belt body 11 penetrates upward through the connecting buckle 2 and bends downward to form a bent portion 112. The bent portion 112 is connected to the connecting buckle 2, and an elastic pressing piece 3 for pressing and fixing the first belt body 11 is connected to the connecting buckle 2.

[0029] Compared with the prior art, in the static conductive rubber trailing device for vehicles provided in this embodiment, the first belt body 11 is pressed tightly in the connecting buckle 2 by the elastic pressing piece 3. When it is necessary to adjust the trailing length of the rubber belt body 1, only need to loosen the elastic pressing piece 3 to make the first belt body 11 loose, pull the first belt body 11 downward, and then drive the second belt body 12 to move downward, then the adjustment of the trailing length of the rubber belt body 1 can be realized, and the contact state between the second belt body 12 and the ground can be ensured; when the rubber belt body 1 is severely worn and needs to be replaced, only need to disassemble the connecting box 4 to separate the second connecting portion 121 and the first connecting portion 111, and then replace the second belt body 12, which avoids the waste of resources and effectively saves the use cost.

[0030] In this embodiment, a connecting bolt connected to the vehicle body is connected to the connecting buckle 2. Connect the connecting bolt to the vehicle body, adjust the length of the rubber belt body 1, and make the lower end of the second belt body 12 lap on the ground to realize the conduction between the vehicle body and the ground, so as to conduct the static electricity generated by the vehicle body to the ground for release.

[0031] The first belt body 11 passes through the connecting buckle 2 and extends upward and bends downward to form a bent portion 112, so as to reserve a certain length for the rubber belt body 1 to adjust the trailing length. Loosen the elastic pressing piece 3, pull the first belt body 11 downward to realize the adjustment of the trailing length, and at a suitable position, press the elastic pressing piece 3 to fix the first belt body 11. The elastic pressing piece 3 and the first belt body 11 are in surface contact, having a large friction coefficient, good pressing effect and uniform force, which helps to extend the service life of the rubber belt body 1.

[0032] The thickness of the upper part of the second belt body 12 is the same as that of the first belt body 11. The thickness of the lower part of the second belt body 12 gradually increases. At the same time, wear-resistant blocks are bonded to the side of the lower end of the second belt body 12 in contact with the ground to improve the wear resistance of the second belt body 12. Specifically, the wear-resistant blocks are made of cemented carbide materials and are bonded to the second belt body 12 using Chemlok adhesives.

[0033] Furthermore, both the first belt body 11 and the second belt body 12 are made of conductive rubber. Conductive rubber evenly distributes conductive particles such as silver-plated glass, silver-plated aluminum, and silver in silicone rubber. By applying pressure, the conductive particles come into contact, enabling the silicone rubber to have conductive properties. Using conductive rubber can make the conductive performance of the rubber belt body 1 more stable.

[0034] As a specific embodiment of the electrostatic conductive rubber trailing belt for automobiles provided by the present utility model, refer to Figure 2 , the first connecting portion 111 is a clamping groove extending along the width direction of the first belt body 11, and the second connecting portion 121 is a raised block extending along the width direction of the second belt body 12. The raised block is in clamping fit with the clamping groove.

[0035] In this embodiment, a plurality of clamping grooves are arranged at intervals along the running direction of the first belt body 11, and a plurality of raised blocks are arranged at intervals along the running direction of the second belt body 12. Through the one-to-one clamping fit of the plurality of raised blocks and the plurality of clamping grooves, and by sleeving the connecting box 4 around the outer periphery of the first connecting portion 111 and the second connecting portion 121, the stable connection of the first belt body 11 and the second belt body 12 is ensured.

[0036] As a specific embodiment of the electrostatic conductive rubber trailing belt for automobiles provided by the present utility model, refer to Figure 2 , wedge-shaped pressing pieces 5 are respectively connected to the opposite inner walls of the connecting box 4 and are respectively pressed against the first belt body 11 and the second belt body 12 in a one-to-one correspondence. The wedge-shaped pressing pieces 5 extend along the running direction of the first belt body 11 or the second belt body 12.

[0037] In this embodiment, the thickness of the connection position between the first belt body 11 and the second belt body 12 is greater than the thickness of the first belt body 11 or the second belt body 12 and less than the sum of the thicknesses of the first belt body 11 and the second belt body 12. Therefore, there are gaps between the inner wall of the connecting box 4 and the first belt body 11 or the second belt body 12. By providing the wedge-shaped pressing pieces 5 to fill the above gaps, it is possible to prevent the first belt body 11 or the second belt body 12 from shaking within the connecting box 4, thereby avoiding affecting the connection effect of the first connecting portion 111 and the second connecting portion 121.

[0038] Furthermore, the wedge-shaped pressing pieces 5 protrude from the connecting box 4, which helps to increase the stability of the connection position. At the same time, the wedge-shaped pressing pieces 5 are closely attached between the connecting box 4 and the first belt body 11 or the second belt body 12, which can prevent dust from entering the connecting box 4 and ensure the effectiveness of the connection.

[0039] As a specific embodiment of the electrostatic conductive rubber trailing device for vehicles provided by the present utility model, refer to Figure 2 , a clamping platform 51 protruding outward is provided on the outer wall of the wedge-shaped pressing piece 5. The clamping platform 51 extends along the width direction of the wedge-shaped pressing piece 5, and a clamping groove 41 that is in clamping cooperation with the clamping platform 51 is provided through the side wall of the connecting box 4.

[0040] In this embodiment, the rubber belt body 1 is made of conductive rubber material and has a certain elasticity. When installing the wedge-shaped pressing piece 5, the rubber belt body 1 can be bent and squeezed to the other side to provide an installation space for the wedge-shaped pressing piece 5. Push the wedge-shaped pressing piece 5 into the connecting box 4. When the clamping platform 51 slides into the clamping groove 41, the rubber belt body 1 can be released. Under the extrusion of the rubber belt body 1, the wedge-shaped pressing piece 5 can be firmly clamped in the connecting box 4, improving the stability of the connection.

[0041] Since the clamping groove 41 is provided through the side wall of the connecting box 4, when it is necessary to remove the wedge-shaped pressing piece 5, the clamping platform 51 can be pushed inward from the outside of the connecting box 4 first, so that the wedge-shaped pressing piece 5 squeezes the rubber belt body 1, thereby providing space for the clamping platform 51 to escape from the clamping groove 41. At this time, the wedge-shaped pressing piece 5 can be pulled out of the connecting box 4.

[0042] As a specific embodiment of the electrostatic conductive rubber trailing device for vehicles provided by the present utility model, refer to Figure 2 , anti-slip teeth 52 are provided on the side wall of the wedge-shaped pressing piece 5 that fits with the first belt body 11 or the second belt body 12. The tips of the anti-slip teeth 52 are inclined towards the side of the connecting box 4.

[0043] In this embodiment, the anti-slip teeth 52 inclined towards the connecting box 4 increase the friction coefficient between the wedge-shaped pressing piece 5 and the rubber belt body 1, and can firmly grip the surface of the rubber belt body 1 when the connecting box 4 and the rubber belt body 1 slide relative to each other, preventing the connecting box 4 and the rubber belt body 1 from sliding relative to each other, and further ensuring the stability of the connection position.

[0044] As a specific embodiment of the electrostatic conductive rubber trailing device for vehicles provided by the present utility model, refer to Figure 1 and Figure 3, the connecting buckle 2 includes a long slot plate 21, a first cover plate 22 and a second cover plate 23 connected to the same side of the long slot plate 21. The first cover plate 22 is arranged near the lower end of the long slot plate 21, and the second cover plate 23 is arranged near the middle of the long slot plate 21. The lower end of the bent-back portion 112 extends downward between the second cover plate 23 and the long slot plate 21. A wiring terminal 113 extending between the first cover plate 22 and the long slot plate 21 is connected to the lower end of the bent-back portion 112. A conductive bolt 24 for connecting the wiring terminal 113 is provided on the first cover plate 22. The elastic pressing piece 3 is connected to the first cover plate 22 by a fastening bolt 25.

[0045] In this embodiment, the lower end of the bent-back portion 112 extends downward between the second cover plate 23 and the long slot plate 21, and the wiring terminal 113 is extended between the first cover plate 22 and the long slot plate 21. The wiring terminal 113 is connected to the first cover plate 22 by the conductive bolt 24, which is convenient for realizing the connection between the first belt body 11 and the connecting buckle 2. At the same time, the elastic pressing piece 3 can be fixed on the first cover plate 22 through the fastening bolt 25, and the elastic pressing piece 3 is pressed against the first belt body 11 by tightening the fastening bolt 25 to realize the fixation of the first belt body 11. In the above process, the long slot plate 21 and the second cover plate 23 play a role in guiding and stabilizing the first belt body 11, and the first cover plate 22 plays a role in connection and fixation.

[0046] Further, an elastic bent plate can be arranged on the inner side of the second cover plate 23 to make the elastic bent plate fit on the surface of the first belt body 11 and elastically deform with the bending angle of the first belt body 11 to protect the first belt body 11 and prevent the first belt body 11 from being damaged due to excessive bending.

[0047] Specifically, the first cover plate 22, the second cover plate 23 and the long slot plate 21 are of an integral structure, and the first cover plate 22 and the second cover plate 23 can be formed by folding the edges of the long slot plate 21. More specifically, the first cover plate 22 and the second cover plate 23 are arranged at the same height, which is convenient for the first cover plate 22 and the second cover plate 23 to be formed at one time. To ensure that the wiring terminal 113 can maintain a straight connection state, a gasket can be added between the wiring terminal 113 and the first cover plate 22. The conductive bolt 24 is threadedly connected to the first cover plate 22. After its extending end passes through the gasket, it is inserted into the round hole of the wiring terminal 113 to realize the connection between the first belt body 11 and the connecting buckle 2.

[0048] More specifically, the wiring terminal 113 in this embodiment is an aluminum alloy die-cast terminal with higher strength, making the connection between the wiring terminal 113 and the connecting buckle 2 more reliable.

[0049] As a specific embodiment of the electrostatic conductive rubber trailing belt for automobiles provided by the present utility model, see Figure 3 and Figure 4, the elastic pressing piece 3 includes a fixing plate 31 located outside the first cover plate 22 and a bending plate 32 connected to the lower edge of the fixing plate 31. The bending plate 32 has a pressing portion 321 extending toward the long groove plate 21 to press against the first belt body 11. The extending end of the fastening bolt 25 sequentially penetrates through the fixing plate 31 and the first cover plate 22 and presses against the pressing portion 321.

[0050] In this embodiment, the fastening bolt 25 is threadedly connected to the first cover plate 22. By tightening the fastening bolt 25, the fixing plate 31 can be pressed against the outside of the first cover plate 22. At the same time, its extending end pushes the pressing portion 321 inward, causing the bending plate 32 to undergo elastic deformation so that the pressing portion 321 presses against the first belt body 11.

[0051] As a specific implementation manner of the electrostatic conductive rubber trailing belt for automobiles provided by the present utility model, refer to Figure 1 and Figure 5 , a counterweight 6 is connected to the second belt body 12. The counterweight 6 includes a first clamping plate 61 and a second clamping plate 62 respectively attached to both side walls of the second belt body 12. An elastic clamping member penetrating through the second clamping plate 62 is connected to the first clamping plate 61.

[0052] In this embodiment, by providing the counterweight 6 on the second belt body 12, it can ensure that the second belt body 12 hangs down and maintains contact with the ground, preventing the second belt body 12 from detaching from the ground when the vehicle jolts and affecting the conductive effect.

[0053] The first clamping plate 61 and the second clamping plate 62 are clamped at appropriate positions on the second belt body 12 through the elastic clamping member, and the installation positions of the first clamping plate 61 and the second clamping plate 62 can be interchanged, and the installation operation is simple. Warning signs are provided on the outer side walls of the first clamping plate 61 and the second clamping plate 62, and the warning signs are made of luminous materials.

[0054] As a specific implementation manner of the electrostatic conductive rubber trailing belt for automobiles provided by the present utility model, refer to Figures 5 to 7 , the elastic clamping member is an elastic column 63 connected to the side wall of the first clamping plate 61. The outer extending end of the elastic column 63 is provided with a convex portion 631 extending radially outward and located outside the second clamping plate 62. Axial slits 632 extending axially and radially penetrating are provided on the peripheral wall of the elastic column 63, and the axial slits 632 extend to the outer extending end of the elastic column 63 so that the elastic column 63 forms two elastically openable and closable clamping portions.

[0055] In this embodiment, the second clamping plate 62 is provided with an installation hole 621 corresponding to the elastic column 63 and having a diameter adapted to that of the elastic column 63. The maximum outer diameter of the convex portion 631 is greater than the aperture of the installation hole 621, so that the convex portion 631 can be clamped outside the second clamping plate 62 to prevent the second clamping plate 62 from detaching from the first clamping plate 61.

[0056] Specifically, the axial notch 632 divides the elastic column 63 into two opposite clamping parts, and the two clamping parts are elastic. When the second clamping plate 62 approaches the first clamping plate 61, the convex part 631 first contacts the edge of the mounting hole 621. Due to the arc-shaped setting of the convex part 631, the convex part 631 can easily slide into the mounting hole 621. Under the extrusion of the hole wall of the mounting hole 621, the two clamping parts approach each other, enabling the convex part 631 to pass through the mounting hole 621. When the convex part 631 completely passes through the mounting hole 621, the two clamping parts return to their original state under the action of their own elasticity, realizing the clamping connection between the second clamping plate 62 and the first clamping plate 61. When it is necessary to disassemble the counterweight 6, it is necessary to manually squeeze the convex part 631 first to make the two clamping parts approach each other and shrink into the mounting hole 621, and at the same time, pull the first clamping plate 61 and the second clamping plate 62 respectively to separate them.

[0057] The setting of the elastic clamping part replaces the bolt connection method of the counterweight 6 in the prior art, and the installation operation is more convenient.

[0058] As a specific implementation manner of the electrostatic conductive rubber trailing chain for automobiles provided by the present utility model, refer to Figure 1 and Figure 6 , a plurality of positioning holes 122 are arranged through the second belt body 12 at intervals along the direction of the second belt body 12, and positioning columns 64 are arranged on the first clamping plate 61 and are in plug-in fit with the positioning holes 122.

[0059] In this embodiment, through the plug-in fit between the positioning column 64 and the positioning hole 122, it is possible to prevent the counterweight 6 from sliding along the second belt body 12 and detaching from the second belt body 12, losing the counterweight effect. On the other hand, when the second belt body 12 is worn, by relaxing the first belt body 11 through the elastic pressing piece 3, when the second belt body 12 moves downward to contact the ground again, it is necessary to correspondingly adjust the position of the counterweight 6 upward. Therefore, a plurality of positioning holes 122 are arranged on the second belt body 12 for the counterweight 6 to cooperate with the positioning column 64 when moving upward.

[0060] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
