Description

Technical Field

[0001] The present invention relates to the field of truck spoilers, and more particularly to a spoiler adjustment device for a heavy truck top. Background Art

[0002] The spoiler on the top of a heavy-duty truck is an important automotive component, designed to optimize the aerodynamic performance of the truck, reduce air resistance during driving, reduce fuel consumption, improve the driving efficiency of the truck, and improve the driving stability of the truck. The driving speed of a truck under different working conditions (such as highways, mountainous areas, cities, etc.) often varies greatly. In order to better optimize the aerodynamic performance of the truck, the top spoiler is usually set to be adjustable. By adjusting the angle of the top spoiler to adapt to different working conditions, the adjustment component used to adjust the top spoiler of a heavy-duty truck needs to be lubricated regularly to reduce the friction between the parts in the adjustment component and increase the service life of the adjustment component.

[0003] Existing heavy truck top spoiler adjustment devices usually require manual addition of lubricating oil to the adjustment components, which is very inconvenient, time-consuming and labor-intensive, and easily results in waste of lubricating oil. Summary of the invention

[0004] The purpose of the present invention is to overcome the defects in the prior art and provide a heavy truck top spoiler adjustment device which can add lubricating oil by adjusting an adjustment component.

[0005] To achieve the above object, the technical solution of the present invention is to provide a heavy truck top spoiler adjustment device, comprising: An adjustment component is connected to the front of the vehicle and one end of the top spoiler, the other end of the top spoiler is rotatably connected to the front of the vehicle, and the adjustment component is used to adjust the angle of the top spoiler; An oil delivery assembly, comprising an oil delivery tank mounted on the regulating assembly, and a piston slidably matched with an inner cavity of the oil delivery tank, wherein the oil delivery tank is connected to a lubrication area of ​​the regulating assembly through an oil delivery pipe; An oil storage tank is installed on the front of the vehicle, and the oil storage tank is connected with the inner cavity through a connecting pipe.

[0006] By using the heavy truck top spoiler adjustment device described in the present invention, the addition of lubricating oil can be completed by pressing the piston, which is convenient and quick to operate, saving time and effort, and the amount of lubricating oil added by one press can be controlled by controlling the volume of the oil tank, ensuring that the lubricating oil is added in sufficient amount and that too much lubricating oil is not added to cause waste.

[0007] Preferably, the piston comprises a plug head, a plug rod and a baffle connected in sequence, the plug head is slidably connected to the inner cavity, the plug rod extends out of the outer ring of the oil delivery tank and is provided with a return spring, one end of the return spring abuts against the baffle, and the other end of the return spring abuts against the outer surface of the oil delivery tank. With such a design, the piston can be automatically reset by the return spring, simplifying the operation process of adding lubricating oil.

[0008] Preferably, the oil delivery tank is provided with an oil inlet and an oil outlet, the oil delivery pipe is connected to the oil outlet, the connecting pipe is connected to the oil inlet, the piston gradually blocks the oil inlet after initial pressing, and a one-way valve is provided on the oil delivery pipe. With this design, only a very small part of the lubricating oil returns to the connecting pipe from the oil inlet, and the lubricating oil remaining in the oil delivery pipe will not be sucked into the oil delivery tank during the piston resetting process, which is conducive to improving the oil delivery effect.

[0009] Preferably, the adjustment assembly includes a bearing seat, a bearing, a screw, a sleeve, a universal coupling and a hand crank, wherein the bearing seat is rotatably connected to the front of the vehicle through a mounting bracket, the oil tank is fixedly mounted on the bearing seat, the bearing is mounted in the bearing seat, the screw is fixedly sleeved with the inner ring of the bearing, the sleeve is threadedly driven and connected to the screw, the sleeve is rotatably connected to the top spoiler through a connecting frame, the oil delivery pipe is connected to the cavity of the sleeve, the output end of the universal coupling is fixedly connected to the screw, and the input end of the universal coupling is fixedly connected to the hand crank. With such a design, the screw can be driven to rotate by rotating the hand crank, thereby driving the sleeve to rise or fall, and then driving the rear end of the top spoiler to move up and down, so that the angle of the top spoiler changes, and the angle adjustment of the top spoiler is completed.

[0010] Preferably, the top outer ring of the shaft sleeve is threadedly sleeved with a shaft cover, the top of the shaft cover is provided with a mounting hole, one end of the oil pipeline is fixedly installed in the mounting hole, and the top inner wall of the shaft cover is fixedly installed with an elastic sealing sheet for closing the mounting hole, the elastic sealing sheet is provided with a plurality of elastic sealing petals corresponding to the mounting holes, and the elastic sealing petals are stressed. Such a design can prevent the lubricating oil in the oil pipeline from oxidizing and deteriorating and clogging the oil pipeline.

[0011] Preferably, the outer ring of the sleeve is fixedly sleeved with a pressure plate for pressing the piston. With this design, by turning the hand crank to move the sleeve down to the bottom, the pressure plate on the sleeve will press the piston, completing the automatic addition of lubricating oil.

[0012] Preferably, a threaded hole is provided on the top of the piston, and a bolt is threadedly connected in the threaded hole. With such a design, the amount of lubricating oil automatically added at one time can be controlled by adjusting the distance between the bolt and the baffle, so as to adapt to different types of lubricating oil.

[0013] Preferably, the bearing is made of non-metal, a sealing cover is installed at the bottom of the bearing, and a cavity communicating with the inside of the bearing is arranged at the top of the bearing seat. With such a design, the lubricating oil can lubricate the bearing by increasing the amount of lubricating oil added.

[0014] Preferably, two filters are arranged in the cavity, the two filters are symmetrically arranged about the center line of the screw, the filters are fixedly mounted on the bearing seat by screws, and the filters include a semicircular filter plate. With this design, the filters can filter the lubricating oil flowing to the bearing to ensure the cleanliness of the lubricating oil.

[0015] Preferably, a buckle for fixing the hand crank is fixedly mounted on the vehicle head. Such a design can facilitate the fixing of the hand crank.

[0016] The beneficial effects of the present invention are: 1. The screw rod can be driven to rotate by rotating the hand crank, thereby driving the screw sleeve to rise or fall, and completing the angle adjustment of the top spoiler. When the screw sleeve falls to the bottom, the pressure plate on the screw sleeve will press the piston, thereby pressing the lubricating oil in the oil tank into the lubrication area, and completing the lubrication of the threaded connection between the screw rod and the screw sleeve. When the hand crank is turned to make the screw sleeve rise again, the reset spring will automatically push the piston to reset. The present invention has a simple structure, low production cost, and convenient and quick addition of lubricating oil.

[0017] 2. By adjusting the distance between the bolt and the baffle, the amount of lubricating oil added can be controlled, which is suitable for different types of lubricating oils, and the bearing can be lubricated by controlling the addition of more lubricating oil at one time.

[0018] 3. Before the lubricating oil flows into the bearing, the filter will filter the lubricating oil to remove dust particles and impurities to ensure that the lubricating oil has a good lubricating effect on the bearing. The filter is installed on the bearing seat with screws. By removing the filter, it is easy to clean the filter.

[0019] 4. By setting the position of the oil inlet, the piston will gradually block the oil inlet after the initial pressing, ensuring that the lubricating oil in the oil tank is basically pressed into the oil pipe, and then flows into the shaft sleeve to lubricate the lubrication area and even the bearing. By setting a one-way valve, the lubricating oil in the oil pipe will not flow back into the oil tank during the piston resetting process, ensuring the oil delivery efficiency and reducing the volume requirement of the oil tank. It not only reduces the manufacturing cost of the oil tank, but also facilitates the installation of the oil tank on the bearing seat.

[0020] 5. By setting an elastic sealing sheet, when no lubricating oil is added, the elastic sealing sheet can prevent dust particles from entering the oil pipeline and clogging the oil pipeline. It can also prevent the lubricating oil in the oil pipeline from being in contact with oxygen in the air for a long time and oxidizing and deteriorating to clog the oil pipeline. When adding lubricating oil, the elastic sealing plate of the elastic sealing sheet can be opened to ensure that the lubricating oil in the oil pipeline can flow into the shaft sleeve to lubricate the lubrication area and the bearing.

[0023] The subject matter described herein will now be discussed with reference to example embodiments. It should be understood that the discussion of these embodiments is to enable those skilled in the art to better understand and implement the subject matter described herein. The functions and arrangements of the elements discussed may be changed without departing from the scope of protection of the present specification. Various examples may omit, replace or add various processes or components as needed. In addition, the features described relative to some examples may also be combined in other examples.

[0024] In order to better understand the present invention, Figure 1-Figure 16 The heavy truck top spoiler adjusting device of the present invention is described in detail.

[0025] Embodiment 1: like Figure 1-Figure 5 As shown, the heavy truck top spoiler adjustment device comprises: The adjustment component 100 is connected to the front of the vehicle and one end of the top spoiler 600, and the other end of the top spoiler 600 is rotatably connected to the front of the vehicle. The adjustment component 100 is used to adjust the angle of the top spoiler 600; The oil delivery assembly 200 includes an oil delivery tank 210 mounted on the regulating assembly 100 and a piston 220 slidably matched with an inner cavity 211 of the oil delivery tank 210. The oil delivery tank 210 is connected to the lubrication area of ​​the regulating assembly 100 through an oil delivery pipe 230. The oil storage tank 300 is installed on the front of the vehicle, and the oil storage tank 300 is connected with the inner cavity 211 through the connecting pipe 310.

[0026] It should be noted that the front end of the top spoiler 600 is rotatably connected to the top of the front of the vehicle (not shown in the figure), and the rear end of the top spoiler 600 is connected to the adjusting assembly 100. The adjusting assembly 100 adjusts the angle of the top spoiler 600 by adjusting the height of the rear end of the top spoiler 600; the lubrication area is the area of ​​the adjusting assembly 100 that needs to be lubricated by adding lubricating oil, and the top end of the piston 220 extends out of the outer surface of the oil tank 210. By pressing the piston 220, the lubricating oil in the oil tank 210 can be pressed into the oil pipe 230, and the lubricating oil enters the lubrication area through the oil pipe 230; the oil storage tank 300 stores lubricating oil, and by resetting the piston 220, the lubricating oil in the oil storage tank 300 can be sucked into the oil tank 210 through the connecting pipe 310 under the action of negative pressure.

[0027] In this embodiment, the bottom surface of the oil storage tank 300 is higher than the top surface of the oil delivery tank 210, that is, the liquid level of the lubricating oil in the oil storage tank 300 is always higher than the liquid level of the lubricating oil in the oil delivery tank 210. Under the action of the lubricating oil's own gravity, the lubricating oil in the oil storage tank 300 tends to flow into the oil delivery tank 210, which is conducive to the lubricating oil in the oil storage tank 300 entering the oil delivery tank 210.

[0028] By using the heavy truck top spoiler adjustment device of the present invention, the addition of lubricating oil can be completed by pressing the piston 220, which is convenient and quick to operate, saving time and effort, and by controlling the volume of the oil tank 210, the amount of lubricating oil added by one press can be controlled, ensuring that the lubricating oil is added in sufficient amount and that too much lubricating oil is not added to cause waste.

[0029] Embodiment 2: As an optimization of Example 1, Figure 5-Figure 8 As shown, the piston 220 includes a plug head 221, a plug rod 222 and a baffle 223 which are connected in sequence. The plug head 221 is slidably connected to the inner cavity 211. The plug rod 222 extends out of the outer ring of the oil tank 210 and is provided with a return spring 240. One end of the return spring 240 abuts against the baffle 223, and the other end of the return spring 240 abuts against the outer surface of the oil tank 210.

[0030] It should be noted that the structure or material of the plug 221 enables it to maintain sealing during the pressing process to prevent the lubricating oil from leaking from the gap between the plug 221 and the oil tank 210. For example, a sealing ring or a sealing sleeve can be set on the outer ring of the plug 221. A through hole 212 connected to the inner cavity 211 is opened on the top of the oil tank 210. The plug rod 222 is slidably connected to the through hole 212. The return spring 240 is located between the top surface of the oil tank 210 and the bottom surface of the baffle 223. By pressing the baffle 223, the piston 220 can be driven to move downward, and the lubricating oil in the inner cavity 211 can be pressed into the oil pipe 230. During this process, the return spring 240 is compressed. When no external force is applied to the baffle 223, the return spring 240 pushes the baffle 223 to move upward under the action of the restoring force of the return spring 240 until the piston 220 is reset.

[0031] Embodiment 3: As an optimization of Example 2, Figure 5 and Figure 6 As shown, the oil tank 210 is provided with an oil inlet 213 and an oil outlet 214 , the oil pipe 230 is connected to the oil outlet 214 , the connecting pipe 310 is connected to the oil inlet 213 , the piston 220 gradually blocks the oil inlet 213 after initial pressing, and a one-way valve 250 is provided on the oil pipe 230 .

[0032] It should be noted that the oil inlet 213 and the oil outlet 214 are both connected to the inner cavity 211. After the piston 220 is pressed, the plug 221 gradually blocks the oil inlet 213 to prevent the lubricating oil in the oil tank 210 from continuously returning to the connecting pipe 310 from the oil inlet 213. As the plug 221 is gradually pressed downward, the lubricating oil in the oil tank 210 is gradually squeezed out from the oil outlet 214 until the plug 221 is pressed to the bottom, and the plug 221 completely blocks the oil outlet 214. At this time, the lubricating oil in the oil tank 210 is completely squeezed out, and the plug 221 still keeps blocking the oil inlet 213. During the process of resetting the piston 220, the plug 221 gradually moves upward. By providing a one-way valve 250 on the oil delivery pipe 230, the lubricating oil remaining in the oil delivery pipe 230 will not be sucked into the oil delivery tank 210. When the plug 221 releases the blockage of the oil inlet 213, the lubricating oil in the oil storage tank 300 is sucked into the oil delivery tank 210 through the connecting pipe 310 under the action of the negative pressure inside the oil delivery tank 210. Through such a design, a good oil delivery effect can be ensured, the requirement for the volume of the oil delivery tank 210 is reduced, and the installation of the oil delivery tank 210 is facilitated.

[0033] In this embodiment, one end of the oil delivery pipe 230 is fixedly installed in the oil outlet 214 , and one end of the connecting pipe 310 is fixedly installed in the oil inlet 213 .

[0034] Embodiment 4: As an optimization of Example 3, Figure 2 , Figure 4 , Fig. 9 and Fig.10 As shown, the adjustment assembly 100 includes a bearing seat 110, a bearing 120, a screw 130, a sleeve 140, a universal coupling 150 and a hand crank 160. The bearing seat 110 is rotatably connected to the front of the vehicle through a mounting bracket 510, the oil tank 210 is fixedly mounted on the bearing seat 110, the bearing 120 is mounted in the bearing seat 110, the screw 130 is fixedly sleeved with the inner ring of the bearing 120, the sleeve 140 is threadedly driven and connected to the screw 130, the sleeve 140 is rotatably connected to the top spoiler 600 through a connecting frame 170, the oil pipe 230 is communicated with the cavity 141 of the sleeve 140, the output end of the universal coupling 150 is fixedly connected to the screw 130, and the input end of the universal coupling 150 is fixedly connected to the hand crank 160.

[0035] It should be noted that the mounting bracket 510 is fixedly mounted on the front of the vehicle, the bearing seat 110 is rotatably connected to the mounting bracket 510 via a rotating shaft, the inner ring of the bearing 120 is fixedly sleeved on the outer ring of the non-threaded section at the bottom of the screw 130, and by providing the bearing 120, the friction resistance of the screw 130 during rotation can be reduced, the wear of the screw 130 can be reduced, the service life of the adjustment assembly 100 can be increased, and the maintenance cost of the adjustment assembly 100 can be reduced. By providing the bearing seat 110, the bearing 120 can be protected; The cavity 141 is a hollow cavity in the screw sleeve, and the threaded connection between the screw 130 and the sleeve 140 is a lubrication area. The sleeve 140 is rotatably connected to the rear end of the top spoiler 600 through the connecting frame 170. The universal coupling 150 is a prior art, and its specific structure is not repeated here. By setting the universal coupling 150, the hand crank 160 and the screw 130 are not in a straight line, and the power transmission can be completed, so that the angle adjustment of the top spoiler 600 can be completed by rotating the hand crank 160. By manually rotating the hand crank 160, the screw rod 130 is driven to rotate, thereby driving the screw sleeve to rise or fall, and then driving the rear end of the top spoiler 600 to move up and down, so that the angle of the top spoiler 600 changes, and the angle adjustment of the top spoiler 600 is completed. During this process, the angles between the screw rod 130 and the shaft sleeve 140 and the horizontal plane will change, and the bearing seat 110 and the bearing 120 will adaptively rotate on the mounting bracket 510 to cooperate with the deflection of the screw rod 130.

[0036] Embodiment 5: As an optimization of Example 4, Figure 2 , Figure 4 , Fig.11 , Fig.12 and Fig.13As shown, the shaft cover 180 is threadedly sleeved on the outer ring of the top of the shaft sleeve 140, and a mounting hole 181 is set through the top of the shaft cover 180. One end of the oil pipe 230 is fixedly installed in the mounting hole 181, and an elastic sealing sheet 190 for closing the mounting hole 181 is fixedly installed on the top inner wall of the shaft cover 180. The elastic sealing sheet 190 is provided with a plurality of elastic sealing petals 191 corresponding to the mounting holes 181, and the elastic sealing petals 191 are subjected to force.

[0037] It should be noted that one end of the oil pipe 230 away from the oil outlet 214 is fixedly installed in the mounting hole 181, and the sleeve 140 can play a dust-proof role to prevent dust particles from entering the sleeve 140 from the opening at the top of the sleeve 140. The lubricating oil will oxidize and deteriorate after long-term contact with oxygen in the air. These oxides are dissolved or dispersed in the lubricating oil in the oil pipe 230, which can easily cause the oil pipe 230 to be blocked. When the piston 220 is not pressed to add lubricating oil, the multiple elastic sealing petals 191 fit tightly together to seal the mounting hole 181 to prevent the lubricating oil in the oil pipe 230 from contacting the outside air. When the piston 220 is pressed to add lubricating oil, the elastic sealing petals 191 are pressed to open, and the lubricating oil flows into the sleeve 140 from the gaps between the multiple elastic sealing petals 191 to lubricate the lubrication area.

[0038] In this embodiment, the elastic sealing sheet 190 is made of polytetrafluoroethylene, and four elastic sealing petals 191 are provided.

[0039] Embodiment 6: As an optimization of Example 5, Figure 3 , Figure 5 and Fig.10 As shown, a pressure plate 142 for pressing the piston 220 is fixedly sleeved on the outer ring of the shaft sleeve 140 .

[0040] It should be noted that by rotating the hand crank 160 to move the sleeve 140 to the bottom, the pressure plate 142 will press the piston 220, thereby completing the addition of lubricating oil. In this way, the driver does not need to enter the area between the front of the vehicle and the body of the vehicle to manually press the piston 220, which greatly improves the convenience of adding lubricating oil.

[0041] Embodiment 7: As an optimization of Example 6, Figure 5-Figure 7 As shown, a threaded hole 2221 is provided on the top of the piston 220 , and a bolt 260 is threadedly connected to the inner thread of the threaded hole 2221 .

[0042] It should be noted that the threaded hole 2221 passes through the baffle 223 and extends into the plug rod 222. Different types of lubricating oils require different amounts of lubricating oil to be added. The pressure plate 142 presses the bolt 260 to press the piston 220, causing the piston 220 to move downward and squeeze the lubricating oil in the oil tank 210. By adjusting the distance between the bolt 260 and the baffle 223, the amount of lubricating oil automatically added at one time can be controlled to adapt to different types of lubricating oils.

[0043] Embodiment 8: As an optimization of Example 7, Fig.10 and Fig.14 As shown, the material of the bearing 120 is non-metallic, a sealing cover 121 is installed at the bottom end of the bearing 120, and a cavity 111 connected to the inside of the bearing 120 is arranged at the top of the bearing seat 110.

[0044] It should be noted that by increasing the distance between the bolt 260 and the baffle 223, the amount of added lubricating oil is increased, so that the lubricating oil flows into the lubrication area and continues to flow downward, enters the bearing 120 through the cavity 111, and lubricates the bearing 120. The sealing cover 121 can prevent the lubricating oil from leaking.

[0045] Embodiment 9: As an optimization of Example 8, Fig.10 , Fig.14 and Fig.15 As shown, two filter screens 400 are arranged in the cavity 111 , and the two filter screens 400 are symmetrically arranged about the center line of the screw 130 . The filter screens 400 are fixed on the bearing seat 110 by screws, and the filter screens 400 include a semicircular filter plate 410 .

[0046] It should be noted that after the two filters 400 are installed, the two filter plates 410 are assembled to form a large annular filter plate. The inner ring of the filter 400 fits against the outer ring of the non-threaded section at the bottom of the screw 130, and the filter 400 is located above the bearing 120. During the process of lubricating the lubrication area with the lubricating oil of the screw 130, some dust particles and impurities will be taken away. The filter 400 can filter the lubricating oil flowing to the bearing 120, and the dust particles and impurities will remain on the filter plate 410. The clean lubricating oil flows into the bearing 120 through the filter holes of the filter plate 410 to lubricate the bearing 120. The filter 400 can be removed by unscrewing the screws for easy cleaning.

[0047] Embodiment 10: As an optimization of Example 9, Figure 2 and Fig.16 As shown, a buckle 520 for fixing the hand crank 160 is fixedly installed on the front of the vehicle.

[0048] It should be noted that the buckle 520 is provided with a slot 521, and the buckle 520 is made of elastic material. The hand crank 160 is fixed in the slot 521 to prevent the hand crank 160 from shaking and colliding with the front or body of the truck during driving.

[0049] In this embodiment, the hand crank 160 includes an inclined section 161, and the slot 521 is inclined. The inclined section 161 is fixed in the slot 521. This can prevent the hand crank 160 from vibrating continuously and rotating around its own center line when the truck is driving, causing the screw 130 to rotate, so that the angle of the top spoiler 600 changes, affecting the spoiler effect of the top spoiler 600.

[0050] The embodiments of the invention are described above in conjunction with the accompanying drawings, but the present embodiment is not limited to the above-mentioned specific implementation modes, which are merely illustrative and not restrictive. Under the guidance of the present embodiment, ordinary technicians in this field can make many forms without departing from the purpose of the present embodiment and the scope of protection of the claims, all of which are within the protection of the present embodiment.
