Description

Technical Field

[0001] The utility model relates to the technical field of vehicle anti-static technology, in particular to an electrostatic conductive rubber trailing strap for automobiles. Background Art

[0002] Articles 12.6.8 and 12.12.1 of the standard GB7258-2017 "Technical Conditions for the Safe Operation of Motor Vehicles" stipulate that natural gas and hazardous chemical vehicles must be equipped with an electrostatic conductive rubber trailing strap device, and the belt body must always be grounded. The standard JT / T 230-2021 "Automobile Electrostatic Conductive Rubber Trailing Strap" requires that this device is not prone to generating sparks during use to ensure the safety of the vehicle in special environments. According to the above standards, a variety of electrostatic conductive rubber trailing straps have been proposed in the prior art. For example, the electrostatic conductive rubber trailing strap for automobiles with the authorization announcement number CN214823089U has its belt body installed on the vehicle through a fixed structure, and a conductive body and a fixed structure are arranged and connected inside the belt body to improve the electrostatic conductive performance of the device. However, this scheme uses an "8"-shaped structure to store the rubber belt, making the volume of the entire trailing strap large and the overall shape not smooth. Therefore, it is not convenient to be applied to vehicles with a lower chassis, thus affecting the scope of use.

[0003] In view of the above problems, the electrostatic conductive rubber trailing strap for automobiles with the authorization announcement number CN203228726U has been improved by adjusting the "8"-shaped structure to a single-loop bending structure. However, this scheme requires the use of multiple bolts to fix the conductive clip and the rubber belt, and its installation is relatively cumbersome. Moreover, when adjusting the length of the rubber belt, multiple bolts also need to be adjusted correspondingly, resulting in a time-consuming and laborious adjustment process. Summary of the Utility Model

[0004] In view of this, the utility model provides an electrostatic conductive rubber trailing strap for automobiles. By setting a pressure strip and a locking tongue on the connecting seat to form a buckle-type structure, and opening a tooth groove on the rubber belt, the spare section is locked by the cooperation of the tooth groove and the buckle-type structure. When adjusting the length of the rubber belt, only need to pull it outwards to make the rubber belt produce a large elastic deformation, and the locking tongue disengages from the tooth groove, then the length of the rubber belt can be pulled and adjusted, thus making it more convenient for users to adjust the length of the trailing strap.

[0005] The technical solution of the utility model is realized as follows: The utility model provides an electrostatic conductive rubber trailing strap for automobiles, including a connecting seat and a rubber belt, wherein,

[0008] Based on the above technical solutions, preferably, it further includes an alloy conductive strip, which is embedded in the fixed section, the spare section and the trailing section and extends out of the end of the trailing section that contacts the ground.

[0009] Further preferably, it further includes a conductive component, which is fixed on the connecting seat and is electrically connected to the alloy conductive strip through the fixed section.

[0010] Even more preferably, the conductive component includes a connecting terminal and a press riveting bolt. Among them,

[0011] One end of the connecting terminal is fixed on the alloy conductive strip;

[0012] The press riveting bolt is fixed on the connecting seat and fixes the other end of the connecting terminal to the connecting seat.

[0013] Based on the above technical solutions, preferably, two side baffles are further provided on the connecting seat. The two side baffles are parallel to each other. The two ends of the pressing strip are respectively fixed on the two side baffles.

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0026] Such as Figures 1-4As shown in the figure, the static conductive rubber trailing strip for automobiles of the present utility model includes a connecting seat 1 and a rubber strip 2.

[0027] A pressing strip 11 and a locking tongue 12 are provided on the connecting seat 1, and the connecting seat 1 is used for being installed on an automobile.

[0028] The connecting seat 1 is integrally formed by bending a sheet metal part. It further includes a base plate. The main body of the base plate is a square sheet. The locking tongue 12 is formed by bending at a right angle on the base plate. After bending, both ends of the pressing strip 11 need to be fixed to the base plate. One end can be bent, and the other end can be connected by means such as welding.

[0029] Mounting holes also need to be opened on the base plate. Bolts can be directly used to fix the connecting seat 1 to the vehicle through the mounting holes. It should be noted that during connection, it is necessary to ensure that electricity can be conducted between the connecting seat 1 and the vehicle so that the static electricity on the whole vehicle can be conducted to the connecting seat 1.

[0030] The rubber strip 2 includes a fixed section 21, a spare section 22 and a trailing section 23. One end of the fixed section 21 is fixed inside the connecting seat 1. The spare section 22 is connected end to end with the fixed section 21 and bends through the pressing strip 11 on the connecting seat 1. A plurality of tooth grooves 221 are opened on the spare section 22. The locking tongue 12 is inserted into one of the tooth grooves 221 to cooperate with the pressing strip 11 to staggeredly squeeze the spare section 22 from both sides of the spare section 22, and lock the spare section 22 through the locking tongue 12 and the tooth groove 221. The trailing section 23 is arranged on the spare section 22 and is used for contacting the ground.

[0031] Since the pressing strip 11 and the locking tongue 12 are respectively located on both sides of the spare section 22, and the locking tongue 12 is stuck into the tooth groove 221 to limit the position of the spare section 22, making it relatively fixed to the connecting seat 1. When its length needs to be adjusted, the spare section 22 needs to be pulled towards the side away from the locking tongue 12 to make the locking tongue 12 leave the tooth groove 221, so as to adjust the length of the spare section 22 extending out of the connecting seat 1.

[0032] The fixed end 21 is inserted between the base plate and the pressing strip 11, and one end is fixed to the base plate. The fixed section 21, the spare section 22 and the trailing section 23 are connected in this way to form a long strip-shaped rubber strip 2. The spare section 22 is bent by 180 degrees through the deformation ability of the rubber strip 2 itself to form a curved arc, passes through between the base plate and the pressing strip 11, and is in close contact with the fixed end 21 at the same time.

[0033] The number of tooth grooves 211 provided on the spare section 22 is multiple and they are arranged at equal intervals. Each tooth groove 211 corresponds to a different extending length of the trailing section 23.

[0034] In addition, the length of the towing section 23 is a fixed length. After the towing section 23 is completely worn out, the rubber belt 2 needs to be replaced. The thickness of the towing section 23 is greater than that of the spare section 22 to improve the wear resistance of the towing section 23.

[0035] In this embodiment, an alloy conductive bar 3 is also provided. The alloy conductive bar 3 is embedded in the fixed section 21, the spare section 22 and the towing section 23, and extends out of the end of the towing section 23 that contacts the ground. The alloy conductive bar 3 forms a grounding structure of the vehicle by contacting the ground during the driving of the vehicle to conduct the static electricity of the vehicle. One end of the alloy conductive bar 3 away from the ground is electrically connected to the connection seat 1, and thus an electrical connection with the vehicle is formed.

[0036] In order to enable the alloy conductive bar 3 to be electrically connected to the connection seat 1 and thus connect to the vehicle, a conductive component 4 is also provided. The conductive component 4 is fixed on the connection seat 1 and is electrically connected to the alloy conductive bar 3 through the fixed section 21. The alloy conductive bar 3 and the connection seat 1 are electrically connected through the conductive component 4, which has good connection stability and can avoid problems such as easy deformation and fracture of the structure caused by directly connecting the alloy conductive bar 3 to the connection seat 1.

[0037] Specifically, the conductive component 4 includes a connection terminal 41 and a riveting bolt 42. One end of the connection terminal 41 is fixed on the alloy conductive bar 3, and the riveting bolt 42 is fixed on the connection seat 1 and fixes the other end of the connection terminal 41 to the connection seat 1.

[0038] One end of the connection terminal 41 is in a circular ring shape, and the other end is welded to the alloy conductive bar 3 or is integrally formed with the alloy conductive bar 3 of the same material. Considering the service life, it is preferably integrally formed. The riveting bolt 42 passes through the circular end of the connection terminal 41 and presses it tightly on the substrate of the connection seat 1 to form a stable electrical connection.

[0039] As a preferred embodiment, two side flanges 13 are also provided on the connection seat 1. The two side flanges 13 are parallel to each other. The two ends of the pressing strip 11 are respectively fixed on the two side flanges 13. The fixed section 21 is accommodated between the two side flanges 13, and the spare section 22 passes between the two side flanges 13 and leaves the connection seat 1, so as to form a guiding structure for the spare section 22 through the two side flanges 13.

[0040] Specifically, the two sides of the substrate are bent to form two side stoppers 13 perpendicular to the substrate. It is equivalent to that the two side stoppers 13 and a locking tongue 12 form a three-sided enclosure on three sides of the substrate. Two sides are formed by the side stoppers 13, which are used to prevent the rubber belt 2 from skewing and guide its spare section 22. The side where the locking tongue 12 is formed is used to cooperate with the tooth groove 221 to clamp the spare section 22. This setting makes the connector 1 simple in molding, low in cost, and has good mechanical stability. In addition, if it is necessary to further improve the structural stability, the side stopper 13 and the locking tongue 12 can be welded.

[0041] In this embodiment, a counterweight assembly 5 is also provided. The counterweight assembly 5 is fixed on the towing section 23, so that the towing section 23 can stably contact the ground and is not drifted due to the inertia of the vehicle. It should be noted that the counterweight assembly 5 should not be set at a position too close to the ground on the towing section 23, and should be at a certain distance from the ground, preferably in the middle of the towing section 23, so as to avoid excessive wear of the rubber belt 2 caused by too low a center of gravity or wear of the counterweight assembly 5.

[0042] Specifically, the counterweight assembly 5 includes two triangular metal blocks 51. The two triangular metal blocks 51 are respectively arranged on both sides of the towing section 23 and are relatively fixed. The two triangular metal blocks 51 are fixed from both sides of the towing section 23 through two screws.

[0043] As a preferred embodiment, a locking bolt 6 is also provided. The locking bolt 6 is arranged on the pressing strip 11 and is threadedly connected with the pressing strip 11. One end of the locking bolt 6 presses on the spare section 22 to squeeze the spare section 22 towards the connector 1.

[0044] The locking bolt 6 can further fix the spare section 22 on the connector 1 to prevent the locking tongue 12 from leaving the tooth groove 221 when the towing section 13 is impacted, so that the spare section 22 moves on the connector 1. When the length of the rubber belt 2 needs to be adjusted, the locking bolt 6 can be loosened and then adjusted. After the adjustment is completed, the locking bolt 6 is tightened again. On the contrary, the cooperation between the piece 12 and the tooth groove 221 can also prevent the locking bolt 6 from loosening and other situations. This double-insurance setting can further improve the structural reliability, and at the same time, it is more convenient and simple than the existing adjustment method.

[0045] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
