The installation of the side-out type current collector of the first embodiment and the structure matching relationship with the electric vehicle are as follows: referring to the figure, the supporting base and the plate 1 connect the two side-out type current collectors through the partial holes of the mounting hole group 27 on it. Installed on the left and right sides of the electric vehicle chassis are not only behind the front wheel, but also between the side beam and the body skin, and the height is such that the hoop 22 and the hoop fastening bolt on the trough-shaped swing bracket 21 The upper surface of the nut set 23 is close to the lower edge of the car body skin skirt so that the trough-shaped swing support rod 21 can swing back freely, and the distance from the bottom of the hoop 22 to the ground is greater than the minimum ground clearance of the car, making the rubber coating conductive The tilted position and shape size of the flat rocker 24 are adapted to the position, shape and size of the gap between the wheel and the fender of the car body, and the rubber-coated conductive flat rocker 24 and the insulating concave ring sleeve 25, The conductive chute 26 can be hidden in the gap in the swing back state without affecting the appearance of the car, and an elastic guiding sloping pallet with the outer side obliquely downward and toward the rear of the car is added at the corresponding position under the fender, corresponding to the sloping pallet The bending part of the swing back rocking rod 24 may be extended to the outside of the vehicle for a short length but not beyond the outside of the vehicle to guide the rubber-coated conductive flat rocking rod 24 and the objects on it to swing back and lift the rubber-coated conductive flat rocking The rod 24 also shields the muddy debris raised by the tire from splashing on the insulating concave ring sleeve 25 and the conductive chute 26 on the tilt rod 24. Figure 1 shows the structure diagram of the side-out current collector installed on the left side of the car when the car is traveling from right to left as shown in the figure. The side-out current collector installed on the right side of the car has the same structure and works as the left side. The same, except that the installation position and working method are symmetrical to the left side of the car with respect to the center line of the car. The side-out type current collectors on the left and right sides are also interlocked by the circuit switch and cannot be exhibited at the same time. Receiver.

The structural coordination and the coordination relationship with the vehicle and the function of the side-out type power receiver of the first embodiment are as follows: the rotation axis 11 of the rotary table 10 and the integrally manufactured quarter-turn electric actuator 8 with an output rotation angle displacement of 90° coincide with the axis line The relationship is welded and manufactured as a whole. A bent swing arm 18 is welded at the center of the circle under the turntable 10, and the bent swing arm 18 passes through the center hole of the washer sheet 7 and the lower hole of the turntable seat 2, and the bent swing arm 18 is required. After the center hole of the tray that receives the grease dripping (the oil tray is not shown in the figure), the turntable 10 is installed in the hole seat of the turntable seat 2 and pressed tightly, and then the upper end surface of the turntable 10 and the turntable seat 2. After selecting the corresponding thickness of the washer sheet 7 for the height difference of the upper end surface of 2, apply grease to the upper and lower end faces, cylinder surface and washer sheet 7 of the turntable 10, and put the selected washer sheet 7 through the core of the rotary electric actuator 8. After the rotor (ie the rotor), place it on the upper end surface of the turntable 10 in the turntable base 2, buckle the round housing 6 (ie the stator) of the quarter-turn electric actuator 8 so that the other end of the rotating shaft 11 enters the upper end of the round housing 6 In the hole, the pressure plate 4 integrated with the round housing 6 is driven to press the washer sheet 7 and the turntable 10 at the same time, and the turntable 10 and the washer sheet 7 are assembled on the turntable seat 2 and the pressure plate 4 through the assembly bolt and nut group 3 distributed in the circumference. In between, a swing device with flexible rotation and proper tension is formed.

After passing the bent swing arm 18 through the mounting holes of the support base and the plate 1, align the circumferential uniform holes on the turntable base 2 with the circumferential uniform holes on the support base and the plate 1, and install the bolt and nut set 15 Pass through the aisle hole on the pressure plate 4, and fix the two symmetrical pendulums on the left and right sides of the chassis of the electric vehicle through the supporting base and the plate 1. The two connecting hanging plates 19 that are opposite to each other from the front of the vehicle are shown in the figure 1 is welded on the left and right sides of the trough-shaped swing bracket 21 viewed from the front end of the vehicle, and the trough-shaped swing bracket 21 is fixed on the hole of the bent swing arm 18 by connecting the fixing bolt and nut group 20; The right end of the rubber-coated conductive cable 17 and the left end of a rubber-coated conductive flat warped rod 24 are connected by soldering to form a flat strip before coating, and then after coating, the two same rubber-coated tin-welded connection flat strips are laminated Placed in the groove of the trough-shaped swing support rod 21 as shown in FIG. 1, a plurality of the hoop 22 and a corresponding number of the hoop fastening bolt and nut groups 23 are formed as shown in FIG. 1 and fixed on the trough-shaped swing support rod 21. The glue-coated conductive flat warped rod 24 on the right end of the groove 21 and the two insulated glue-coated conductive cables 17 in the left section shown in the lower left side of Figure 1 make the two rubber-coated conductive cables 17 the most The left end of the conductive joint is respectively connected to the electric vehicle input current connection pile head and the output current connection pile head.

The upturned section of the upper inner rod of the rubber-coated conductive flat tilt rod 24 is higher than that of the outer rod, so that the inner rod can contact the power supply slide line on the side of the road without being blocked by the outer rod. The inner and outer rods are tilted and tilted. The blocked elastic flexibility of the two rods eliminates the mutual interference upturning section, so as to ensure that the conductive sliding grooves 26 welded on the inner and outer rods can contact the power supply slide line and slide forward.

The conductor chute 26 for input current and output current is welded on the uncoated section of the end section of the rubber-coated conductive flat rocker 24 as shown in Fig. 1, using the larger groove width of the conductor chute 26 In order to facilitate the driving of the trough-shaped swing support rod 21 to contact the power supply slide line set on the side of the road with a uniform ground height and up and down fluctuation range; the upper and lower ends of the conductive chute 26 are used to prevent electric vehicles from being on the road. The bumps and pits cause the vehicle to knock the supporting rods and arms of the power supply slide line one by one by driving the power slide line that is caused by the up and down shaking of the trough-shaped swing support rod 21; The smoothness of the road surface is required, and the smoothness of the road needs to be monitored and maintained. Strip-shaped fine grooves along the width direction of the groove are formed on the inner bottom of the conductive slide groove 26 and are embedded with grease to reduce friction and wear. When the conductive chute 26 is worn to the limit as a worn part, it can be removed and replaced with a new part and welded again. The upper and lower end blocks of the conductive slide 26 are bent into a hook shape relative to the horizontal plane in the free state of the vehicle, which can absorb the elastic deformation of the hook block when the upper and lower vibrations hit the power supply slide line Vibration energy can be used to hook the power supply slide line on the side of the road while sliding forward to avoid falling off and leaving the power supply slide line.

The upturned sections of the two rubber-coated conductive flat warped rods 24 are each bonded around the shaft of the rubber-coated conductive flat warped rod 24 as shown in Figure 1 on the outer insulating section below the welded conductor chute 26 Wrap up a ring of dense insulating concave ring sleeve 25 that is concave upwards to eliminate the current short circuit caused by rain and snow infiltration, and make one more insulating concave ring sleeve on the long rubber-coated conductive flat warped rod 24 at the inner side. 25. Make it at the back of the conductor chute 26 at the outer low side to further ensure that the right end of the conductive flat warped rod 24 at the lower outer side will not touch the inner side when it is wet. The long rubber-coated conductive flat warped rod 24 leaks electricity.

The electric conductor chute 26 uses the central part of the electric conductor chute 26 to contact the power supply sliding line on the side of the road under the effect of the rotation and swing force transmitted from the quarter-turn electric actuator 8 Before manufacturing and installation, Yamato side-out type power receivers have carried out the chute position and groove width for the fixed ground height and the upper and lower fluctuation range of the power supply slide line on the side of the road to adapt to the change of the distance from the vehicle side and the fluctuation of the power supply slide line. The width is determined by the need for the vibration of the sliding groove 26 to fluctuate up and down. Therefore, when the switch is turned on to promote the display of the side-out current collector, it can ensure smooth contact and adapt to the change of the distance between the vehicle side and the power supply sliding line and the up and down vibration. Vibrate to ensure contact and keep it from falling off.

The groove-shaped swing support rod 21 is welded to the lower lug 16, and a cylindrical sleeve 9 is fitted under the round housing 6 of the quarter-turn electric actuator 8. The lower end of the cylindrical sleeve 9 is supported by the pressure plate 4, and the cylindrical sleeve 9 can The pressure plate 4 is free to rotate around the round housing 6 of the quarter-turn electric actuator 8. The upper pull ear 13 is welded to the wall 5 of the cylinder sleeve 9 by using the front and rear upper pull ear welding heads 12 shown in FIG. A square steel plate is vertically welded to the wall 5 of the cylindrical sleeve 9 to form an upper pull ear 13. The upper hook of the pull spring 14 hooks the upper pull ear 13, and the pull hook of the pull spring 14 hooks the lower ear 16 to tighten the groove upward. The swinging amount of the groove-shaped swinging support rod 21 relative to the gap between the turntable base 2 (that is, the fixedly connected vehicle chassis) is caused by the turntable 10 and the turntable base 2, the pressure plate 4 and the gasket 7 The assembly clearance of the bending arm 18 and the connecting hanger plate 19 are reduced to zero due to the matching clearance of the connecting and fixing bolt and nut group 20, and the tension of the tension spring 14 is determined by practice without affecting After the normal rotation of the turntable 10, the effect of the gap is eliminated, and the sloshing caused by the gap is prevented from being amplified by the long groove-shaped swinging support rod 21, which further reduces the amount of up and down free sway of the conductive slide groove 26, and improves the contrast with the power supply slide line. It also reduces the frequency that the upper and lower blocks of the conductor chute 26 are hit by the upper and lower edges of the power supply slide line during contact sliding, and also increases the downward elastic retreat during the impact, ensuring the integrity and integrity of the conductor chute 26 reliability. In addition, because the elastic force of the elastic washers of more than half of the bolts and nuts on the outer side of the bolt and nut group 15 is strengthened and not completely compressed, a little elastic deformation is reserved to overcome the upward impact and shaking of the stopper on the chute 26 .

The tension spring 14 is close to the outer edge of the turntable base 2, and is rotated by the cylindrical sleeve 9 around the round housing 6 of the quarter-turn electric actuator 8 with the swing of the groove-shaped swing support rod 21. The support base and the plate 1 are cut away One corner is shown in Figure 2, so that the tension spring is not interfered by collision and can rotate with the groove-shaped swing support rod 21 in a 90° corner, which not only ensures the reduction of shaking, but also closes the support base and the plate 1, so The size increase is small, which can prevent the tension spring 14 from scratching the inner side of the body skin when the trough-shaped swing support rod 21 is swung out of the skirt of the body skin.

Since the left front end of the trough-shaped swing support rod 21 is installed on the chassis of the vehicle close to the rear side of the front wheel along with the support base and the plate 1, the tilted section of the rubber-coated conductive flat tilting rod 24 and the conductive The body chute 26 and the insulating concave ring sleeve 25 are concealed and installed in the gap between the rear wheel and the fender, so that their length is close to the wheelbase of the vehicle minus the outer diameter of the tire. For ordinary cars, the length is about It is about 1.7 meters, which allows the car to drive in the middle of the carriageway on the power supply slide line and 0.35 meters away from the power supply slide line, so that the conductive chute 26 can touch the power supply slide on the side of the road. Therefore, there is no need to coat the front section of the conductive flat rocker 24 with the lower edge of the front wheel fender to bend around the front tire and install the support base and the plate 1 on the side of the chassis in front of the front wheel. It is necessary to bypass the lower edge of the rear wheel fender and extend the rubber-coated conductive flat rocker 24 to the rear end of the car to stand up, or to drag it downwards diagonally behind the rear wheel and the rear of the car to reach the extended rubber-coated conductive flat shape The tilting rod 24 can touch the power supply slide line on the side of the road when it is swung out, so as to slide for electricity. Of course, for cars with a very short wheelbase, the rubber-coated conductive flat rocker 24 should go around the front tires along with the lower edge of the front wheel fender on the turntable 10, and for very small single-row cars. Further, the lower edge of the wheel fenders bypasses the rear tires, and even extends to the rear end of the vehicle to stand up. At the same time, because the length is large, there is greater flexibility, so as to absorb the up and down vibration caused by the extra large unevenness of the road surface and cause the energy and elastic deformation of the upper and lower edges of the electric conductor sliding groove 26 to hit the power supply sliding line up and down.

The left end of the rubber-coated conductive flat warped rod 24 and the rubber-coated conductive cable 17 are connected by soldering, which has good conductivity and low tensile strength. It is also held by a series of hoop 22 through the corresponding number of hoop fastening bolt and nut groups 23 It is tightly fixed in the groove of the trough-shaped swing support rod 21, which not only ensures the normal conductive power transmission and power extraction, but also prevents the occurrence of the conductive chute 26, the rubber-coated conductive flat warped rod 24, and the insulating concave ring sleeve 25. , Hoop 22 and other hidden dangers when it is hung and not slipping, can be easily pulled off by the car, and the solder joints can be pulled off by the car without pulling off the driving car and pulling the power supply slip line.

The bent swing arm 18 is welded to the center of the lower circle of the turntable 10, and at the same time, the hanging end of the rubber-coated conductive cable 17 in the groove-shaped swing support rod 21 is located at the swing center under the turntable 10 to make the rubber-coated The conductive cable 17 does not affect the connection with the electric pile head of the input and output current on the vehicle due to the large swing caused by the swing of the groove-shaped swing bracket 21, and the fatigue life of itself due to the bending of the swing and avoid collision interference. Other parts.

Combining the height of the vehicle structure and the chassis to adjust the support base and the installation of the plate 1 and the vehicle chassis, and make the axis of the turntable 10 and the shaft 11 have a certain vertical deflection relative to the inner and outer directions of the vehicle side, so that the turntable 10 can be relative to the road side When the distance of the power supply slide line is different, due to the deflection of the axis of the turntable 10, the groove-shaped swing bracket 21 has different swing angles due to the different swing distances. The different positions of the swing angle cause the groove-shaped swing bracket 21 to deflect up and down. The angle is different, causing the conductor chute 26 to be in different distances from the power supply slide line on the side of the car before swinging out, so that it touches different up and down positions after swinging out, so that the upper and lower positions of the conductor chute 26 are evenly worn and durable. The up and down fluctuations of the power supply slide line make the conductor slide 26 wear even and durable.

The right end section of the rubber-coated conductive flat warping rod 24 is tilted, except for the elastic large swing flexibility that prevents the blocked conductor chute 26 from moving outwards, and it does not block the other wing-coated conductive flat warping rod 24 from moving. Eliminate the mutual interference of the conductor chutes 26 on the two rubber-coated conductive flat warped rods 24 to ensure that they can contact their own power supply slide lines to take electricity. Because the rubber-coated conductive flat warped rods 24 are thin, soft and An obtuse angle is formed. It is not easy to hook the support rod and connection of the power supply slide line after the conductor chute 26 slips off the power supply slide line due to excessive vibration from the car. In case the hook is also easily stretched off or hanged due to the obtuse angle Pull off the insulating concave ring sleeve 25 to prevent the car from running sideways. The conductor chute 26 is on the outer and rear side of the end section of the rubber-coated conductive flat rocker 24, and the left and right side edges of the middle of the conductor chute 26 are always in contact with the sliding power supply sliding line; in order to increase the contact surface area of the contact power supply sliding line, The bend of the rubber-coated conductive flat warped rod 24 was bent slightly inwardly before the exhibition, so that the end section of the conductive flat warped rod 24 was coated when the conductor chute 26 squeezed the power supply slide line. With deflection to increase the contact area during exhibition, it can also further make the conductive chute 26 and the bare metal at the end of the rubber-coated conductive flat rocker 24 only be welded (or bolted and riveted) to the front side (or Use a conductive metal sheet to fold into an acute-angle conductive chute base with greater elasticity and weld it to the end section of the rubber-coated conductive flat rocker 24) to form the end section elastically opening backwards relative to the direction of the vehicle to make it conductive When the body chute 26 contacts the power supply slide line and is squeezed, the conductor chute 26 not only deflects to the rear of the vehicle elastically, but also sticks to the power supply slide line as much as possible along the front and rear direction of the vehicle, increasing the contact area and reducing the resistance. , Reduce wear and tear. At the same time, the conductor chute 26 is located on the obtuse-angled outer back of the rubber-coated conductive flat rocker 24 and can be turned from the side of the vehicle with the rocker 24, which can also prevent the conductor chute 26 from falling off the power supply slide line and hooking. Support rod and connection of power supply slide line. The worst case is as mentioned above: pull off the hoop 22 and break the solder joint of the rubber-coated conductive cable 17 when it is hung, so as to prevent the car from being pulled off and the supporting rod and connection of the power supply slide line from being damaged.

The power-taking process of electric vehicles and side-out receivers is as follows:

When an electric vehicle uses the stored electric energy to drive to a road with a power supply slipline, it drives into the lane with the power supply slipline and brings the vehicle side close to the power supply slipline, and turns on the side-out power receiver switch on the side of the power supply slipline. Through the three-position two-way interlocking of the switch, the side-out type receiver switch on the other side of the car is locked. At the same time, the output angle of the side-out type receiver that is connected to the power supply is 90° angular stroke electric actuator 8 After the power is turned on, the power is delayed. The remaining electromagnet force makes the rotating shaft 11 drive the rotating shaft 11 and the rotating shaft 11 to be welded into a coaxial line and the turntable 10 and the bent swing arm 18 can rotate 90 from the inside to the outside of the car and to the front of the car. °, because the horizontal end of the bent swing arm 18 is slightly deviated to the inside of the car during installation, the bent swing arm 18 pushes the connecting crane that clamps the bent swing arm 18 itself through the connecting fixing bolt and nut group 20 The plate 19 can be rotated and the groove-shaped swing bracket 21 welded in a vertical relationship with the connecting hanger plate 19 is stopped when it rotates 90° to close to the vertical state with the vehicle side, and the groove-shaped swing bracket 21 drives its groove to be surrounded by a series of hoop 22. The rubber-coated conductive flat rocking rod 24 and the conductive sliding groove 26 and the insulating concave ring sleeve 25 on the end section are held tightly and lifted up. They are turned out from the rear of the vehicle to the outside and the front of the vehicle. The rubber-coated conductive cable 17 connected to the rubber-coated conductive flat rocker 24 by soldering in the oscillating support rod 21 is connected to the power transmission joint on the vehicle during deflection. Because the conductor chute 26 is very wide, the middle of the chute is It can smoothly touch the power slide line on the side of the road when it is placed. And because the distance between the side of the car and the power supply slide line is less than the length of the trough-shaped swing bracket 21 (and also less than the overtaking distance), the general trough-shaped swing bracket 21 has not been swung to a sharp clamp of less than 90° close to the vertical side of the vehicle. The angle makes the conductor chute 26 contact the power supply slide line to take power and slide to continue taking power for the vehicle to run and charge and store.

Because under the compensation of the elastic deflection of the rubber-coated conductive flat warped rod 24, the two overlapping end sections of the input and output currents are tilted up to be a rubber-coated conductive flat warped with a high inner upper root and a lower outer lower root. The rod 24 can eliminate mutual interference and can respectively contact the corresponding power supply slide lines at the upper and lower positions; at the same time, because the axis of the rotating shaft 11 and the turntable 10 are superimposed on one line and the upper part of the shaft is slightly inclined toward the side of the car, the trough-shaped swinging bracket When the end of the rod 21 is swung out, the more it is swung outward, the higher it will be. This allows the conductor slide 26 on the side of the car to have different distances from the power supply slide line due to different rotation angles and different height positions in the contact groove. And make the wear uniform.

When a car accidentally encounters severe and excessive road surface bumps, the upper and lower blocks of the conductive slide 26 prevent the conductive slide 26 from separating from the power supply slide line and swing the long shaft of the support rod 21 in the groove shape. The spring 14 cooperates to overcome the downward impact force and shaking of the lower stop of the chute 26; in addition, the elastic washers of the half of the bolts and nuts on the outside of the vehicle where the bolt and nut group 15 are installed are strengthened and not completely compressed. Leave a little amount of elastic deformation to overcome the upward impact force and shaking on the upper block of the chute 26.

The fixed side-out receiver of the electric vehicle changes its distance from the power slide line when the vehicle is running, and the electromagnet force of the quarter-turn electric actuator 8 also pushes forward and the blocking force of the power slide line. , The conductor chute 26 keeps in contact with the power supply slide line and slides to take electricity to drive the electric vehicle while charging and storing until it is fully charged, and continues to slide to take electricity for the motor to drive the car; the car can also take part of the electricity and leave the power supply Lane, when the sensor on the car senses that there is no current and no power is taken, it triggers the controller to immediately retract the side-out current collector and disconnect the side-out current collector from the circuit on the car. Then, in the conductor chute 26 Leaving the power slip line or shaking off the power slip line due to huge bumps and bumps on the road while driving, and the car is still driving in the power lane, the side-out power collector will be immediately retracted within milliseconds to ensure that the side-out power receiver is not Wipe and hang other moving vehicles and the supporting parts of the power supply slipline; electric vehicles can also make full use of other non-power supply lanes to achieve the purpose of normal fast driving without being hindered by the slow movement of the preceding vehicle.

After power is taken, when the distance between the side of the vehicle and the power supply slide line is less than the normal driving distance, the sensor on the vehicle senses the safe setting value of the return position of the trough-shaped swing support rod 21 for taking power or the upper and lower inner and outer sides are coated with a conductive flat When the rocker bar 24 cannot touch the respective power supply slipline at the same time and the power is cut off, it will immediately trigger the alarm to ring and flash and trigger the controller to immediately retract the side-out current collector and fix it in the car to avoid collisions with the power supply slipline and roads. The guardrail also prevents the conductor chute 26 from being separated from the power supply sliding line and continuously hitting the power supply sliding line support rod and connection due to the vibration of the power supply sliding line when the car hits and the influence of the inner and outer inclination angle of the rotating shaft 11 and the turntable 10.

Turn off the power switch, the reverse delayed current will make the quarter-stroke electric actuator 8 form a reverse electromagnet force and maintain it, and rotate the shaft 11 to drive the turntable 10 and the bent swing arm 18, and make the groove swing through transmission The supporting rod 21 drives the rubber-wrapped conductive flat rocker rod 24 and the conductive chute 26 on it to swing back into the car, then the side-out current collector is immediately retracted, and the side-out current collector is completely retracted in the power supply lane. , Avoid the side-out current collector from wiping other vehicles to ensure safety. After the side-out power receiver is retracted, the rubber-coated conductive flat rocker 24 is guided by the elastic guiding inclined support plate added under the car wing panel to the inclined support plate itself, which is supported by the electromagnet. The force keeps pushing into the car and is blocked and fixed by the car.

When the vehicle is driving close to the fork of the lane and does not exit the intersection, the conductor chute 26 will follow the vehicle and drive at the intersection until it leaves the power supply slip line. Of course, the power supply slip line on the side of the fork can also be approached when it exits. When power is not supplied to the fork road section, the vehicle sensor immediately triggers the controller when it senses that there is no current, and immediately retracts the side-out current collector within the safe milliseconds of pre-investigation and statistics, so as to avoid rubbing other vehicles and objects in the fork road section.

When starting to take power, when the side-out power receiver is fully exhibited and does not touch the power supply slide line with power or the power supply slide line touched has no power, it will be triggered within a safe millisecond when the sensor on the car senses that there is no current without power. The controller immediately retracts the side-out current collector.

The structure and working process of the side-out current collector on the other side of the car are the same as the side-out current collector on the left side of the car, except that the installation and working mode are symmetrical to the left side relative to the center axis of the car.

For electric vehicles with a long wheelbase and a high chassis, without reducing the minimum ground clearance of the vehicle, only one side-out current collector can be installed, so that it can be swung out to the left or right of the vehicle to contact power supply as needed The slide line takes electricity to drive, recharges, and returns to the middle position as needed, and is locked and positioned by the controller.

The second embodiment: the assembly application of the side-out type current collector in the electric vehicle of this embodiment, the difference from the first embodiment is that the bent swing arm 18 of the first embodiment becomes a crane that passes through the lower opening of the turntable base 2. Block 18, the width of the hanging block 18 is equal to the trough-shaped swing support rod 21, and correspondingly, the connecting hanging plate 19 is turned into a bent hanging plate 19 from front to back and then downward to realize the rotating shaft 11 of the turntable 10 and the hanging The overall simplification of the block 18 and the convenience of assembly and the further reduction of the turntable base 2; multiple holes are dug out on the cylindrical sleeve 9 or formed by combined welding to form a cage to reduce weight, save materials, and better heat dissipation. Remove the conductor chute 26, the rear and outer bare surface of the elongated tilted section of the rubber-coated conductive flat tilted rod 24 directly touches the power supply slide line to obtain electricity. The distance between the ends of the inner and outer tilted rods 24 is increased, and the tilted rods 24 24 The upturned section is bent into a shape that can be close to the fender of the tire, and when retracted, it is positioned and fixed on the guide pallet (frame) added between the tire and the fender by the chassis of the vehicle; when the wear exceeds the standard, cut The tilted section of the tilted rod 24 is re-welded and polished smoothly and even grooved with grease. At the same time, the elongated upturned section of the upturned rod 24 is used to prevent the up and down vibration of the huge bumps and convexities of the road from accidentally breaking away from the power supply slip line. Since the tilted section of the tilting rod 24 is added very long, the tension spring 14 and the upper pull ear 13 and the lower ear 16 and the cylindrical sleeve 9 and the upper pull ear welding head 12 can be omitted as needed.

Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be implemented Modifications or equivalent replacements without departing from the purpose and scope of the technical solution of the present invention should be covered by the scope of the claims of the present invention.
