Description

Technical Field

[0001] This invention relates to the field of truck spoilers, and more specifically, to a spoiler adjustment device for heavy-duty trucks. Background Technology

[0002] The spoiler on the top of a heavy-duty truck is an important automotive component designed to optimize the truck's aerodynamic performance, reduce air resistance during driving, lower fuel consumption, improve driving efficiency, and enhance truck stability. Truck speeds often vary significantly under different operating conditions (such as highways, mountainous areas, and urban areas). To better optimize truck aerodynamics, the top spoiler is typically adjustable. By adjusting the angle of the spoiler, it can adapt to different operating conditions. The adjustment assembly for the heavy-duty truck's top spoiler requires regular lubrication to reduce friction between the components and extend the assembly's lifespan.

[0003] Existing heavy-duty truck top spoiler adjustment devices typically require manual addition of lubricating oil to the adjustment components, which is inconvenient, time-consuming, labor-intensive, and prone to lubricating oil waste. Summary of the Invention

[0004] The purpose of this invention is to overcome the defects in the prior art and provide a heavy-duty truck top spoiler adjustment device that allows lubricant to be added by adjusting the adjustment components.

[0005] To achieve the above objectives, the technical solution of the present invention provides a heavy-duty truck roof spoiler adjustment device, comprising:

[0006] An adjustment assembly is connected to one end of the front of the vehicle and the top spoiler, the other end of which is rotatably connected to the front of the vehicle. The adjustment assembly is used to adjust the angle of the top spoiler.

[0007] The oil delivery assembly includes an oil tank mounted on the regulating assembly and a piston that slides within the inner cavity of the oil tank. The oil tank is connected to the lubrication zone of the regulating assembly via an oil delivery pipe.

[0008] An oil reservoir is installed at the front of the vehicle, and the oil reservoir is connected to the inner cavity via a connecting pipe.

[0009] By using the heavy-duty truck top spoiler adjustment device described in this invention, lubricating oil can be added simply by pressing the piston. The operation is convenient, quick, time-saving, and labor-saving. Furthermore, by controlling the volume of the oil tank, the amount of lubricating oil added with each press can be controlled, ensuring that sufficient lubricating oil is added without adding too much lubricating oil and causing waste.

[0010] Preferably, the piston includes a plug head, a plug rod, and a baffle connected in sequence. The plug head is slidably connected to the inner cavity, and the plug rod extends out of the oil tank and is fitted 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 tank. This design allows the piston to automatically return to its original position via the return spring, simplifying the process of adding lubricating oil.

[0011] Preferably, the oil tank is provided with an oil inlet and an oil outlet, the oil supply pipe is connected to the oil outlet, and the connecting pipe is connected to the oil inlet. After the piston is initially pressed, it gradually seals the oil inlet, and a one-way valve is provided on the oil supply pipe. This design ensures that only a very small portion of the lubricating oil returns from the oil inlet to the connecting pipe, and the lubricating oil remaining in the oil supply pipe will not be drawn into the oil tank during the piston's reset process, thus improving the oil supply efficiency.

[0012] Preferably, the adjustment assembly includes a bearing housing, a bearing, a screw, a bushing, a universal coupling, and a hand crank. The bearing housing is rotatably connected to the vehicle head via a mounting bracket. The oil tank is fixedly mounted on the bearing housing. The bearing is installed inside the bearing housing. The screw is fixedly sleeved with the inner ring of the bearing. The bushing is threadedly driven connected to the screw. The bushing is rotatably connected to the top spoiler via a connecting bracket. The oil supply pipe communicates with the cavity of the bushing. 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. This design allows the screw to rotate by rotating the hand crank, thereby causing the bushing to rise or fall, which in turn moves the rear end of the top spoiler up and down, thus changing the angle of the top spoiler and achieving angle adjustment.

[0013] Preferably, a shaft cover is threaded onto the top outer ring of the bushing, and a mounting hole is provided through the top of the shaft cover. One end of the oil supply pipe is fixedly installed in the mounting hole, and an elastic sealing plate for sealing the mounting hole is fixedly installed on the top inner wall of the shaft cover. The elastic sealing plate is provided with multiple elastic sealing flaps corresponding to the mounting hole, and the elastic sealing flaps are subjected to force. This design can prevent the lubricating oil in the oil supply pipe from oxidizing, deteriorating, and clogging the oil supply pipe.

[0014] Preferably, the outer ring of the bushing is fixedly fitted with a pressure plate for pressing the piston. With this design, by rotating the hand crank to move the bushing down to its lowest position, the pressure plate on the bushing will press the piston, thus automatically adding lubricating oil.

[0015] Preferably, the piston has a threaded hole at its top, and a bolt is threaded into the hole. This design allows for control over the amount of lubricating oil added automatically at one time by adjusting the distance between the bolt and the baffle, thus accommodating different types of lubricating oil.

[0016] Preferably, the bearing is made of non-metallic material, a sealing cap is installed at the bottom of the bearing, and a cavity communicating with the interior of the bearing is provided at the top of the bearing housing. This design allows for increased lubrication of the bearing by adding more lubricating oil.

[0017] Preferably, two filter screens are provided within the cavity, symmetrically arranged about the center line of the screw. The filter screens are fixedly mounted on the bearing housing by screws, and each filter screen includes a semi-circular filter plate. This design allows the filter screens to filter the lubricating oil flowing to the bearing, ensuring the cleanliness of the lubricating oil.

[0018] Preferably, a buckle for securing the hand crank is fixedly installed on the front of the vehicle. This design facilitates the securing of the hand crank.

[0019] The beneficial effects of this invention are as follows:

[0020] 1. By rotating the hand crank, the screw can be rotated, thereby causing the screw sleeve to rise or fall, thus adjusting the angle of the top spoiler. When the screw sleeve falls to the bottom, the pressure plate on the screw sleeve will press the piston, thereby forcing the lubricating oil in the oil tank into the lubrication area, completing the lubrication of the threaded connection between the screw and the screw sleeve. When the hand crank is rotated to make the screw sleeve rise again, the return spring will automatically push the piston to return to its original position. This invention has a simple structure, low production cost, and convenient and quick lubrication.

[0021] 2. By adjusting the distance between the bolt and the baffle, the amount of lubricating oil added can be controlled, making it suitable for different types of lubricating oil. Furthermore, by controlling the addition of more lubricating oil at once, the bearing can also be lubricated.

[0022] 3. Before the lubricating oil flows into the bearing, the filter screen filters the lubricating oil, removing dust particles and impurities to ensure that the lubricating oil has a good lubricating effect on the bearing. The filter screen is installed on the bearing housing with screws. The filter screen can be easily cleaned by removing it.

[0023] 4. By setting the position of the oil inlet, the piston will gradually block the oil inlet after the initial press, ensuring that the lubricating oil in the oil tank is basically forced into the oil supply pipe and then flows into the bushing to lubricate the lubrication area and even the bearing. By setting a one-way valve, the lubricating oil in the oil supply pipe will not flow back into the oil tank during the piston reset process, ensuring oil supply efficiency and reducing the volume requirements of the oil tank. This not only reduces the manufacturing cost of the oil tank, but also makes it easier to install the oil tank on the bearing seat.

[0024] 5. By setting up an elastic sealing plate, when no lubricating oil is added, the elastic sealing plate can prevent dust particles from entering the oil supply pipe and clogging it. It can also prevent the lubricating oil in the oil supply pipe from oxidizing and deteriorating due to long-term contact with oxygen in the air and clogging the oil supply pipe. When lubricating oil is added, the elastic sealing plate of the elastic sealing plate can open to ensure that the lubricating oil in the oil supply pipe can flow into the bushing to lubricate the lubrication area and bearing.

[0047] The subject matter described herein will now be discussed with reference to exemplary embodiments. It should be understood that these embodiments are discussed to enable those skilled in the art to better understand and implement the subject matter described herein. Changes may be made to the function and arrangement of the elements discussed without departing from the scope of this specification. Various processes or components may be omitted, substituted, or added as needed in the examples. Furthermore, features described in some examples may be combined in other examples.

[0048] To better understand this invention, the following is combined with... Figures 1-16 The heavy-duty truck roof spoiler adjustment device of the present invention will be described in detail.

[0049] Example 1:

[0050] like Figures 1-5 As shown, the heavy-duty truck roof spoiler adjustment device includes:

[0051] An adjustment component 100 is connected to one end of the front of the vehicle and 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.

[0052] The oil delivery assembly 200 includes an oil tank 210 mounted on the regulating assembly 100 and a piston 220 that slides in cooperation with the inner cavity 211 of the oil tank 210. The oil tank 210 is connected to the lubrication area of ​​the regulating assembly 100 through an oil delivery pipe 230.

[0053] The fuel tank 300 is installed at the front of the vehicle and is connected to the inner cavity 211 via a connecting pipe 310.

[0054] 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 adjustment assembly 100. The adjustment 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 zone is the area where the adjustment assembly 100 needs to add lubricating oil for lubrication. The top 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 forced into the oil pipe 230, and the lubricating oil enters the lubrication zone through the oil pipe 230. The oil reservoir 300 stores lubricating oil. By resetting the piston 220, under the action of negative pressure, the lubricating oil in the oil reservoir 300 can be drawn into the oil tank 210 through the connecting pipe 310.

[0055] 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 to say, the level of the lubricating oil in the oil storage tank 300 is always higher than the 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.

[0056] By using the heavy-duty truck top spoiler adjustment device of the present invention, lubricating oil can be added by pressing the piston 220. The operation is convenient and quick, saving time and effort. Furthermore, by controlling the volume of the oil tank 210, the amount of lubricating oil added with each press can be controlled, ensuring that the lubricating oil is added in sufficient quantity and avoiding excessive addition of lubricating oil, which would result in waste.

[0057] Example 2:

[0058] As an optimization of Example 1, such as Figures 5-8 As shown, the piston 220 includes a plug head 221, a plug rod 222 and a baffle 223 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 fitted 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.

[0059] It should be noted that the construction or material of the plug 221 enables it to maintain a seal during pressing, preventing lubricating oil from leaking from the gap between the plug 221 and the oil tank 210. For example, the outer ring of the plug 221 can be provided with a sealing ring or a sealing sleeve. The top of the oil tank 210 has a through hole 212 communicating with the inner cavity 211. 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, pressing the lubricating oil in the inner cavity 211 into the oil pipe 230. During this process, the return spring 240 is compressed. When no longer applying external force to the baffle 223, under the action of the restoring force of the return spring 240, the return spring 240 pushes the baffle 223 upward until the piston 220 is reset.

[0060] Example 3:

[0061] As an optimization of Example 2, such as 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 supply pipe 230 is connected to the oil outlet 214, and the connecting pipe 310 is connected to the oil inlet 213. After the piston 220 is initially pressed, it gradually blocks the oil inlet 213. A one-way valve 250 is provided on the oil supply pipe 230.

[0062] It should be noted that both the oil inlet 213 and the oil outlet 214 are 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 down, 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, at which point the plug 221 completely blocks the oil outlet 214. At this time, all the lubricating oil in the oil tank 210 is squeezed out, and the plug 221 still blocks the oil inlet 213.

[0063] During the process of resetting the piston 220, the plug head 221 gradually moves upward. By setting a one-way valve 250 on the oil supply pipe 230, the lubricating oil remaining in the oil supply pipe 230 will not be sucked into the oil supply tank 210. When the plug head 221 releases the blockage of the oil inlet 213, under the action of the negative pressure inside the oil supply tank 210, the lubricating oil in the oil storage tank 300 is sucked into the oil supply tank 210 through the connecting pipe 310.

[0064] This design ensures good oil transfer performance, reduces the volume requirements of the oil tank 210, and facilitates the installation of the oil tank 210.

[0065] In this embodiment, one end of the oil pipeline 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.

[0066] Example 4:

[0067] As an optimization of Example 3, such as Figure 2 , Figure 4 , Figure 9 and Figure 10 As shown, the adjustment assembly 100 includes a bearing housing 110, a bearing 120, a screw 130, a bushing 140, a universal coupling 150, and a hand crank 160. The bearing housing 110 is rotatably connected to the front of the vehicle via a mounting bracket 510. The oil tank 210 is fixedly installed on the bearing housing 110. The bearing 120 is installed inside the bearing housing 110. The screw 130 is fixedly sleeved with the inner ring of the bearing 120. The bushing 140 is threadedly driven connected to the screw 130. The bushing 140 is rotatably connected to the top spoiler 600 via a connecting bracket 170. The oil pipe 230 communicates with the cavity 141 of the bushing 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.

[0068] It should be noted that the mounting bracket 510 is fixedly mounted on the front of the vehicle, and the bearing housing 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. By setting the bearing 120, the frictional resistance experienced by the screw 130 during rotation can be reduced, the wear of the screw 130 can be reduced, the service life of the adjustment component 100 can be increased, and the maintenance cost of the adjustment component 100 can be reduced. By setting the bearing housing 110, the bearing 120 can be protected.

[0069] Cavity 141 is the hollow cavity inside the screw sleeve. The threaded connection between the screw 130 and the bushing 140 is the lubrication area. The bushing 140 is rotatably connected to the rear end of the top spoiler 600 through the connecting frame 170. The universal coupling 150 is existing technology, and its specific structure will not be described in detail here. By setting the universal coupling 150, the power can be transmitted even if the hand crank 160 and the screw 130 are not on the same straight line, which makes it easy to adjust the angle of the top spoiler 600 by rotating the hand crank 160.

[0070] By manually rotating the hand crank 160, the screw 130 is rotated, which in turn causes the screw sleeve to rise or fall, thereby causing the rear end of the top spoiler 600 to move up and down, thus changing the angle of the top spoiler 600 and completing the angle adjustment of the top spoiler 600. During this process, the angle between the screw 130 and the bushing 140 and the horizontal plane will change, and the bearing seat 110 and the bearing 120 will rotate adaptively on the mounting bracket 510, cooperating with the deflection of the screw 130.

[0071] Example 5:

[0072] As an optimization of Example 4, such as Figure 2 , Figure 4 , Figure 11 , Figure 12 and Figure 13 As shown, the top outer ring of the bushing 140 is threaded with a bushing cover 180. The top of the bushing cover 180 has a through mounting hole 181. One end of the oil pipe 230 is fixedly installed in the mounting hole 181. An elastic sealing sheet 190 for sealing the mounting hole 181 is fixedly installed on the top inner wall of the bushing cover 180. The elastic sealing sheet 190 is provided with multiple elastic sealing petals 191 corresponding to the mounting hole 181. The elastic sealing petals 191 are subjected to force.

[0073] It should be noted that the end of the oil supply pipe 230 away from the oil outlet 214 is fixedly installed in the mounting hole 181. The bushing 140 can play a dustproof role, preventing dust particles from entering the bushing 140 through the opening at the top of the bushing 140. After prolonged contact with oxygen in the air, the lubricating oil will oxidize and deteriorate. These oxides will dissolve or disperse in the lubricating oil in the oil supply pipe 230, which can easily cause blockage of the oil supply pipe 230. When the piston 220 is not pressed to add lubricating oil, multiple elastic sealing petals 191 are tightly fitted together to seal the mounting hole 181, preventing the lubricating oil in the oil supply pipe 230 from contacting the outside air. When the piston 220 is pressed to add lubricating oil, the elastic sealing petals 191 are opened under pressure, and the lubricating oil flows into the bushing 140 from the gap between the multiple elastic sealing petals 191, and lubricates the lubrication area.

[0074] In this embodiment, the elastic sealing sheet 190 is made of polytetrafluoroethylene, and four elastic sealing flaps 191 are provided.

[0075] Example 6:

[0076] As an optimization of Example 5, such as Figure 3 , Figure 5 and Figure 10 As shown, the outer ring of the bushing 140 is fixedly fitted with a pressure plate 142 for pressing the piston 220.

[0077] It should be noted that by rotating the hand crank 160 to move the bushing 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 to manually press the piston 220, which greatly improves the convenience of adding lubricating oil.

[0078] Example 7:

[0079] As an optimization of Example 6, such as Figures 5-7 As shown, the piston 220 has a threaded hole 2221 on its top, and a bolt 260 is connected to the threaded hole 2221 by an internal thread.

[0080] It should be noted that the threaded hole 2221 passes through the baffle 223 and extends into the plug rod 222. The amount of lubricating oil to be added varies for different types of lubricating oil. The pressure plate 142 presses the piston 220 by pressing the bolt 260, causing the piston 220 to move down 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 added automatically at one time can be controlled to adapt to different types of lubricating oil.

[0081] Example 8:

[0082] As an optimization of Example 7, such as Figure 10 and Figure 14 As shown, the bearing 120 is made of non-metallic material, a sealing cover 121 is installed at the bottom of the bearing 120, and a cavity 111 communicating with the inside of the bearing 120 is provided at the top of the bearing housing 110.

[0083] It should be noted that by increasing the distance between bolt 260 and baffle 223, the amount of lubricating oil added is increased, so that the lubricating oil flows into the lubrication area and continues to flow down, entering the bearing 120 through cavity 111 to lubricate the bearing 120. The sealing cover 121 can prevent lubricating oil leakage.

[0084] Example 9:

[0085] As an optimization of Example 8, such as Figure 10 , Figure 14 and Figure 15As shown, two filters 400 are provided in the cavity 111. The two filters 400 are symmetrically arranged about the center line of the screw 130. The filters 400 are fixedly installed on the bearing seat 110 by screws. The filters 400 include a semi-circular filter plate 410.

[0086] It should be noted that after the two filter screens 400 are installed, the two filter plates 410 are joined together to form a large annular filter plate. The inner ring of the filter screen 400 is attached to the outer ring of the non-threaded section at the bottom of the screw 130, and the filter screen 400 is located above the bearing 120. During the process of the lubricating oil of the screw 130 lubricating the lubrication area, some dust particles and impurities will be carried away. The filter screen 400 can filter the lubricating oil flowing to the bearing 120. The dust particles and impurities remain on the filter plate 410, and 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 screen 400 can be removed by unscrewing the screw for cleaning.

[0087] Example 10:

[0088] As an optimization of Example 9, such as Figure 2 and Figure 16 As shown, a clip 520 for securing the hand crank 160 is fixedly installed on the front of the vehicle.

[0089] It should be noted that the buckle 520 is equipped with a slot 521. 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.

[0090] In this embodiment, the hand crank 160 includes an inclined section 161 and a slot 521 is inclined. The inclined section 161 is fixed in the slot 521, which can prevent the hand crank 160 from vibrating continuously and rotating around its own center line when the truck is moving, causing the screw 130 to rotate and the angle of the top spoiler 600 to change, thus affecting the spoiler effect of the top spoiler 600.

[0091] The embodiments of the invention have been described above with reference to the accompanying drawings. However, the embodiments are not limited to the specific implementation methods described above. The specific implementation methods described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of the embodiments without departing from the spirit of the embodiments and the scope of protection of the claims, and all of these forms are within the protection scope of the embodiments.
