Detailed Implementation

[0019] Embodiments of this disclosure will now be described in more detail with reference to the accompanying drawings. While some embodiments of this disclosure are shown in the drawings, it should be understood that this disclosure can be implemented in various forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of this disclosure. It should be understood that the accompanying drawings and embodiments of this disclosure are for illustrative purposes only and are not intended to limit the scope of protection of this disclosure.

[0020] In the description of embodiments of this disclosure, the term "comprising" and similar terms should be understood as open-ended inclusion, i.e., "including but not limited to". The term "based on" should be understood as "at least partially based on". The term "one embodiment" or "the embodiment" should be understood as "at least one embodiment". The term "some embodiments" should be understood as "at least some embodiments". Other explicit and implicit definitions may also be included below.

[0021] As mentioned earlier, to improve the rapid deployment capability of air compressor equipment, some air compressors are deployed on mobile platforms such as chassis, enabling them to be quickly deployed to application scenarios without a fixed air source, such as industrial sites, construction sites, and rescue sites. In some cases, this type of air compressor equipment can also be called "mobile air compressor equipment." In traditional technologies, some chassis are relatively small in size and simple in structure. However, the structural strength of these chassis is usually low, making it difficult to support high-power air compressor systems with relatively large weights.

[0022] To meet the load-bearing requirements of high-power air compression systems, some manufacturers increase the chassis's load-bearing capacity by increasing its size, using high-strength profiles, and adding more wheel sets (e.g., two pairs of wheel sets, two wheels per set). However, these chassis are typically large and heavy, structurally complex, and costly to produce. Furthermore, their mobility is usually relatively poor, limiting the application scenarios for air compression equipment. Therefore, it is evident that traditional mobile platforms for air compression equipment often struggle to balance structural strength and simplicity.

[0023] To address, or at least partially address, the aforementioned problems or other potential problems existing in conventional technologies, embodiments of this disclosure provide an improved chassis design. In this improved design, the chassis includes a base plate and at least one reinforcing structure disposed on the base plate. The reinforcing structure includes an inverted groove structure, a support beam, and multiple reinforcing bodies. The inverted groove structure is formed by a portion of the base plate bulging upwards. The support beam is disposed within the inverted groove structure and extends along its length. The multiple reinforcing bodies are spaced apart along the length of the inverted groove structure, and each reinforcing body penetrates two opposite sidewalls of the inverted groove structure and the support beam along its width, and is fixedly connected to the two sidewalls and the support beam.

[0024] According to embodiments of the present disclosure, the inverted groove structure formed by the upward bulge of a portion of the bottom plate in the chassis already functions as a reinforcing rib. By providing support beams within the inverted groove structure, the structural strength of the reinforced structure can be improved. By providing multiple reinforcing elements, the coupling between the inverted groove structure and the support beams can be increased, and the load can be distributed, further enhancing the structural strength of the reinforced structure. Deploying this reinforced structure significantly improves the chassis's load-bearing capacity. While meeting load requirements, it facilitates a reduction in chassis size, simplifies the chassis structure, and lowers production costs.

[0025] Some exemplary embodiments of this disclosure will now be described in detail with reference to the accompanying drawings.

[0026] Figure 1 and Figure 2 Perspective views of an air compression device according to some embodiments of the present disclosure are shown from different angles. Figure 3 A perspective view of a chassis according to some embodiments of the present disclosure is shown. Figure 4 An exploded view of a chassis according to some embodiments of the present disclosure is shown. Figure 5 A top view of a chassis according to some embodiments of the present disclosure is shown. Figure 6 It shows Figure 5 A cross-sectional view of the reinforcing structure along the BB line. See also... Figures 1 to 6 As shown, the chassis 100 of the present disclosure includes a base plate 121 and at least one reinforcing structure 170 disposed on the base plate 121. The various components of the chassis will be described below with reference to the accompanying drawings and examples.

[0027] In some embodiments, the base plate 121 can be a monolithic structure. For example, the base plate 121 can be formed from a single sheet of material (such as by stamping or bending). Alternatively, such as Figure 5 As shown, the base plate 121 may include multiple plates 130, which are connected to form the base plate 121. As an example, in conjunction with... Figure 4 and Figure 5 As shown, the base plate 121 may include a first plate 131, a second plate 132 and a third plate 133 arranged sequentially along the width direction of the chassis 100.

[0028] In some embodiments, the chassis 100 may further include at least one side plate. For example... Figures 3 to 5As shown, the chassis 100 can be generally rectangular in shape. The chassis 100 may include a base plate 121, a first side plate 122, a second side plate 123, a third side plate 124, and a fourth side plate 125. The first side plate 122 and the second side plate 123 may be opposite each other in the width direction of the chassis 100, and the edges of the base plate 121 in the width direction of the chassis 100 are connected to the first side plate 122 and the second side plate 123, respectively. The third side plate 124 and the fourth side plate 125 may be opposite each other in the length direction of the chassis 100, and the edges of the base plate 121 in the length direction of the chassis 100 are connected to the third side plate 124 and the fourth side plate 125, respectively. As an example, a first plate 131 may be connected to the first side plate 122, the two side edges of the second plate 132 may be connected to the first plate 131 and the third plate 133, respectively, and the third plate 133 may be connected to the second side plate 123. Furthermore, the first plate 131 and the first side plate 122 can be of an integral structure, and the third plate 133 and the second side plate 123 can also be of an integral structure. Alternatively or additionally, such as... Figure 1 and Figure 2 As shown, the chassis 100 may also include a traction structure 126, which can be connected to the front end of the base plate 121.

[0029] In some embodiments, the chassis 100 may further include a wheel assembly 110, which is disposed below and supports the base plate 121. Figure 1 and Figure 2 As shown, the wheel assembly 110 may include a pair of wheels and an axle connecting the pair of wheels. When the chassis 100 includes a pair of wheels, not only is the structure simple and the production cost low, but it also offers high flexibility, which is beneficial for expanding the application scenarios of the chassis 100. In this case, the width direction of the chassis 100 may be parallel to or approximately parallel to the axis direction of the axle, and the length direction of the chassis 100 may be parallel to or approximately parallel to the direction of travel during the straight-line movement of the chassis 100. Of course, the wheel assembly 110 is not limited to including a pair of wheels; it may also include multiple pairs of wheels, such as two pairs of wheels. It should be understood that the chassis 100 described above is merely exemplary, and any suitable structure of the chassis 100 can be selected according to actual needs. For example, the chassis 100 may only include a base plate 121 to simplify the chassis structure. Such chassis can be transported by, for example, lifting or shipping. Also, for example, in... Figure 3 and Figure 4 An enclosure, for example, can be provided above the chassis 100 to form a closed chassis 100, thereby improving the chassis's protective performance. The embodiments disclosed herein do not limit this.

[0030] The base plate 121 is provided with at least one reinforcing structure 170. In some embodiments, the base plate 121 may be provided with one reinforcing structure 170. For example, the reinforcing structure 170 may extend along the length direction of the chassis 100 and be located at the center in the width direction of the chassis 100. Alternatively, the base plate 121 may also be provided with multiple reinforcing structures 170. As an example, combined with Figures 3 to 5 As shown, the base plate 121 can be provided with two reinforcing structures 170, which can be referred to as the first reinforcing structure 181 and the second reinforcing structure 182, respectively. Both the first reinforcing structure 181 and the second reinforcing structure 182 can extend along the length of the chassis 100. The first reinforcing structure 181 can be located near the first side plate 122, and the second reinforcing structure 182 can be located near the second side plate 123. In this way, the structural strength of the chassis 100 can be improved, thereby increasing the load-bearing capacity of the chassis 100.

[0031] Alternatively or additionally, if the base plate 121 is provided with multiple reinforcing structures 170, the multiple reinforcing structures 170 may also be arranged in a cross configuration. For example, some of the multiple reinforcing structures 170 may extend along the length direction of the chassis 100, and another portion of the reinforcing structures 170 may extend along the width direction of the chassis 100. Of course, the number and arrangement of the reinforcing structures 170 described above are merely exemplary. In practical applications, any appropriate number of reinforcing structures 170 may be deployed, and the reinforcing structures 170 may be arranged in any appropriate manner. The embodiments of this disclosure do not impose any limitations on this.

[0032] like Figure 3 , Figure 4 and Figure 6 As shown, the reinforcing structure 170 may include an inverted groove structure 171, a support beam 172, and multiple reinforcing bodies 173. The inverted groove structure 171 is formed by a portion of the base plate 121 protruding upwards. The inverted groove structure 171 may include two opposing groove sidewalls 176, 177 and a groove bottom wall 175 connecting the two groove sidewalls 176, 177. It is understood that although it is called the groove bottom wall 175, since the opening of the inverted groove structure 171 faces downwards, the groove bottom wall 175 is actually located at the top of the two groove sidewalls 176, 177, and the two side edges of the groove bottom wall 175 are connected to the upper edges of the two groove sidewalls 176, 177, respectively. Therefore, the groove bottom wall 175 can also be called the "groove top wall," but whether it is called the groove bottom wall 175 or the groove top wall, it refers to the wall opposite the opening of the inverted groove structure 171.

[0033] A support beam 172 is disposed within the inverted groove structure 171 and extends along the length of the inverted groove structure 171. In some embodiments, the support beam 172 may be welded within the inverted groove structure 171. As an example, the longitudinal section of the inverted groove structure 171 may be inverted U-shaped, and the support beam 172 may be made of C-shaped steel or square steel. The bottom side of the support beam 172 may be welded to the opening edge of the inverted groove structure 171, for example, multiple welding points may be spaced apart along the length of the reinforcing structure 170 to fix the support beam 172 within the inverted groove structure 171. Alternatively or additionally, welding holes penetrating the support beam 172 and the inverted groove structure 171 may be provided, and the support beam 172 and the inverted groove structure 171 may be welded together using, for example, a plug welding process. For example, multiple welding holes may be spaced apart along the length of the reinforcing structure 170, and the welding holes may penetrate the bottom wall 175 of the groove and the upper surface of the support beam 172. Alternatively or additionally, the support beam 172 and the inverted groove structure 171 can also be connected by fasteners such as bolts. For example, the support beam 172 and the inverted groove structure 171 can be fixedly connected by bolts that penetrate the bottom wall 175 of the groove and the upper surface of the support beam 172. Of course, the support beam 172 can also be connected to the inverted groove structure 171 by any other suitable connection method.

[0034] Multiple reinforcing elements 173 are spaced apart along the length of the inverted groove structure 171. The reinforcing elements 173 penetrate two opposing groove sidewalls 176 and 177 and the support beam 172 along the width of the inverted groove structure 171, and are fixedly connected to the two groove sidewalls 176 and 177 and the support beam 172. In some embodiments, combined with... Figures 3 to 5 As shown, the reinforcing structure 170 can extend along the length of the chassis 100. In this case, multiple reinforcing bodies 173 can be spaced apart along the length of the chassis 100, and each reinforcing body 173 can penetrate two sidewalls 176, 177 and the support beam 172 along, for example, the width of the chassis 100. In this way, it is beneficial to enhance the structural strength of the chassis 100 and to optimize the mechanical properties of the chassis 100.

[0035] As an example, the two slot sidewalls 176 and 177 can each have a first through hole and a second through hole respectively, and the support beam 172 can have a third through hole opposite to the first and second through holes. The reinforcing body 173 can pass through the first, second, and third through holes. The reinforcing body 173 can be welded to the two slot sidewalls 176 and 177 and the support beam 172, for example, the outer periphery of the reinforcing body 173 can be welded to the inner periphery of the first, second, and third through holes respectively. Of course, the reinforcing body 173 can also be connected to the slot sidewalls 176 and 177 and the support beam 172 in other ways, for example, by locking the reinforcing body 173, the two slot sidewalls 176 and 177, and the support beam 172 with a connector, or the reinforcing body 173 can be snapped into the slot sidewalls 176 and 177 and the support beam 172.

[0036] In some embodiments, such as Figure 3 and Figure 4 As shown, the at least one reinforcing structure 170 includes a first reinforcing structure 181 and a second reinforcing structure 182 arranged in parallel, for example, both extending along the length direction of the chassis 100. The plurality of reinforcing elements 173 of the first reinforcing structure 181 are staggered with the plurality of reinforcing elements 173 of the second reinforcing structure 182. In this way, the mechanical characteristics of the base plate 121 can be further optimized to further improve the structural strength of the chassis 100. Of course, the plurality of reinforcing elements 173 of the first reinforcing structure 181 and the plurality of reinforcing elements 173 of the second reinforcing structure 182 can also be arranged symmetrically. The embodiments of this disclosure do not limit this arrangement.

[0037] In some embodiments, combined with Figure 3 As shown, a channel 174 penetrating the reinforcing structure 170 can be provided within the reinforcing body 173. This allows for the passage of materials such as wires or pipes, facilitating the connection of components or equipment on both sides of the reinforcing structure 170. As an example, the reinforcing body 173 may include a tubular structure (e.g., a circular pipe), through which the channel 174 can be formed. Of course, the above-described reinforcing body 173 is merely exemplary; it can also be formed using, for example, a square pipe or a block-like structure. The embodiments of this disclosure are not limited in this respect.

[0038] In some embodiments, if the base plate 121 comprises a plurality of plates 130, a reinforcing structure 170 may be provided at the connection region between two adjacent plates 130. In this way, the structural strength at the connection region can be improved, and the mechanical properties of the chassis 100 can be optimized. As an example, in conjunction with... Figures 3 to 5As shown, if the base plate 121 includes a first plate 131, a second plate 132 and a third plate 133 arranged sequentially along the width direction of the chassis 100, a first reinforcing structure 181 may be provided at the connection area between the first plate 131 and the second plate 132, and a second reinforcing structure 182 may be provided at the connection area between the second plate 132 and the third plate 133.

[0039] In some embodiments, such as Figure 4 As shown, L-shaped flanges 140 are respectively provided at the opposite edges of two adjacent plates 130. The L-shaped flanges 140 include a vertical flange 141 arranged along the depth direction of the inverted groove structure 171 and a horizontal flange 142 arranged along the width direction of the inverted groove structure 171. The vertical flange 141 is formed by bending the edge of the plate 130 upwards, and the horizontal flange 142 is bent from the upper edge of the vertical flange 141 away from the plate 130. The vertical flanges 141 of the two L-shaped flanges 140 are opposite each other and the two horizontal flanges 142 are superimposed to each other to form the inverted groove structure 171. Specifically, the two vertical flanges 141 can respectively form the two groove sidewalls 176 and 177 of the inverted groove structure 171, and the two superimposed horizontal flanges 142 can form the groove bottom wall 175 of the inverted groove structure 171. In this way, not only can the manufacturing difficulty of the chassis 100 be reduced, but the strength of the reinforcing structure 170 can also be improved by the two overlapping lateral folds 142, thereby improving the load-bearing capacity of the chassis 100.

[0040] Figure 7 It shows Figure 4 A magnified view of part A in the middle, combined with Figure 6 and Figure 7As shown, a first L-shaped flange 150 can be provided on the edge of the third plate 133 (i.e., the edge near the second plate 132). This first L-shaped flange 150 can be formed by bending upwards from the edge of the third plate 133 to form a first vertical flange 151 and by bending from the upper edge of the first vertical flange 151 away from the third plate 133 to form a first horizontal flange 152. A second L-shaped flange 160 can be provided on the edge of the second plate 132 (i.e., the edge near the third plate 133). This second L-shaped flange 160 can be formed by bending upwards from the edge of the second plate 132 to form a second vertical flange 161 and by bending from the upper edge of the second vertical flange 161 away from the second plate 132 to form a second horizontal flange 162. The second horizontal flange 162 can be stacked on top of the first horizontal flange 152. The first horizontal flange 152, the second horizontal flange 162, and the support beam 172 can be fixedly connected by means such as welding or bolting. It should be noted that the first plate 131 and the second plate 132 can also be connected in a similar manner, which will not be described in detail here. It should also be noted that the above-described inverted groove structure 171 is merely exemplary; the inverted groove structure 171 can also be formed by stamping or bending on the base plate 121, or by any other suitable method. The embodiments disclosed herein do not limit this.

[0041] See Figure 1 and Figure 2 As shown, the air compression device of the embodiments of this disclosure may include a chassis 100 and an air compression system 200 as described in any of the above embodiments, with the air compression system 200 mounted on the chassis 100. Because the chassis 100 has high structural strength, it can accommodate an air compression system 200 with relatively high power and weight. If the chassis 110 is equipped with wheel assemblies 110, the air compression device (which can also be referred to as a "mobile air compression device") can maintain relatively high flexibility, which is beneficial for expanding the application scenarios of high-power mobile air compression devices and reducing the production cost of mobile air compression devices.

[0042] In some embodiments, such as Figure 1 and Figure 2As shown, the air compression system 200 may include a compressor main unit 211, an engine 221, an oil tank 222, an oil-gas separator 212, a cooling system 230, and an aftertreatment system 223. The engine 221 may be drivenly connected to the compressor main unit 211, and the engine is adapted to provide power for the operation of the compressor main unit 211. The oil tank 222 may be connected to the engine 221 via, for example, an oil supply line. The aftertreatment system 223 may be connected to the exhaust pipe of the engine 221. The aftertreatment system 223 is adapted to purify the exhaust gas emitted by the engine 221 to reduce the environmental impact of the exhaust gas. The oil-gas separator 212 may be connected to the compressor main unit 211, and the oil-gas separator 212 is adapted to perform oil-gas separation on the oil-gas mixture discharged from the compressor main unit 211. The cooling system 230 may include a fan 231 and at least one cooler 232, the at least one cooler 232 being connected to the oil-gas separator 212 and / or the engine 221.

[0043] In some embodiments, such as Figure 1 and Figure 2 As shown, the at least one cooler 232 may include a first cooler 233, which may be connected to both the oil-gas separator 212 and the compressor main unit 211. The first cooler 233 cools the lubricating oil separated by the oil-gas separator 212, and the cooled lubricating oil can be returned to the compressor main unit 211 for recycling. Alternatively or additionally, the at least one cooler 232 may also include a second cooler 234, which may be connected to the engine 221. The second cooler 234 cools the coolant in the engine 221. Alternatively or additionally, the at least one cooler 232 may also include a third cooler 235. The third cooler 235 may be connected to the air intake of the engine 221, and the third cooler 235 cools the intake air of the engine 221. For example, if the engine 221 is equipped with a turbocharger, the third cooler 235 may be connected between the turbocharger and the air intake of the engine 221.

[0044] In some embodiments, the air compression system 200 may further include a first air filter 213 and a second air filter 224. The first air filter 213 may be connected to the air inlet of the compressor main unit 211, and the second air filter 224 may be connected to the air inlet of the engine 221. During operation, air enters the engine 221 (e.g., a diesel engine 221, a gasoline engine 221, or an engine 221 using other fuels) after being filtered by the second air filter 224, for fuel combustion. The engine 221 can drive the compressor main unit 211 to operate. After being filtered by the first air filter 213, the air flows into the compressor main unit 211. The compressor main unit 211 can perform a compression operation on the air. The oil-air mixture is then discharged into the oil-air separator 212. The oil-air separator 212 performs oil-air separation on the oil-air mixture, and the separated compressed air can be provided to the air-consuming end, such as air-consuming equipment or air-consuming links. The separated lubricating oil, after being cooled by the first cooler 233, can flow back to the compressor main unit 211 for recycling.

[0045] In some embodiments, the post-processing system 223 may be located downstream of the cooling system 230 in the airflow direction. Since the temperature of the post-processing system 223 is relatively high, deploying the post-processing system 223 downstream of the cooling system 230 in the airflow direction can avoid affecting the intake air temperature of the cooling system 230, which is beneficial to improving the cooling efficiency of the cooling system 230.

[0046] As an example, combined Figure 1 and Figure 2 As shown, the compressor main unit 211, engine 221, cooling system 230, and aftertreatment system 223 are arranged sequentially along the length of the chassis 100. For example, the compressor main unit 211, engine 221, cooling system 230, and aftertreatment system 223 can be arranged sequentially from the rear end to the front end of the chassis 100. The compressor main unit 211 can be deployed near the rear end of the chassis 100, the engine 221 can be deployed above the wheel assembly 110, the aftertreatment system 223 can be located at the front end of the chassis 100 (e.g., near the end of the traction structure 126), and the cooling system 230 can be deployed between the engine 221 and the aftertreatment system 223. The first air filter 213 and the second air filter 224 can be deployed near the rear end of the chassis 100. The fuel tank 222 can be deployed near the first side plate 122 and can extend along the length of the chassis 100. Since the engine 221 is relatively heavy, the above-described arrangement allows the center of gravity of the entire machine to be closer to the wheel assembly 110, which is beneficial to improving system stability. Of course, the above arrangement is merely exemplary. The embodiments of this disclosure do not limit the arrangement of the various components of the air compression system 200.

[0047] In some embodiments, the air compression system 200 may further include an electrical system 241 and a control system 242. The control system 242 may be connected to a controlled component or controlled device, such as an engine 221 or a valve, and may also be connected to a detection component, such as a pressure sensor or a temperature sensor. Based on the detection results from the detection component, the control system 242 may control, for example, the engine 221 or the valve, to ensure stable operation of the air compression system 200. The electrical system 241 may include a battery module 250, and may also be connected to a load, such as the control system 242, the detection component, or the valve. The electrical system 241 may control the battery module 250 to supply power to the load. As an example, such as... Figure 1 and Figure 2 As shown, the electrical system 241 can be deployed in the middle of the chassis 100 along its length, and the electrical system 241 can be located near the second side panel 123. The control system 242 can be deployed at the rear end of the chassis 100.

[0048] Figure 8 A perspective view of a battery module 250 according to some embodiments of the present disclosure is shown. Figure 8 As shown, the battery module 250 may include multiple batteries 251. Each battery 251 may have an interface 254 on its top surface, and the multiple batteries 251 may be stacked. In two adjacent batteries 251, the upper battery 251 avoids the interface 254 of the lower battery 251. This not only reduces the space occupied by the battery module 250 but also facilitates the connection of the batteries 251. As an example, the battery module 250 may include a first battery 252 and a second battery 253. The second battery 253 can be connected above the first battery 252 via, for example, a bracket 256, and the second battery 253 avoids the interface 254 of the first battery 252. Furthermore, a protective cover 255 may be provided on the top of the second battery 253, and the interfaces 254 of both the first battery 252 and the second battery 253 are located within the vertical projection area of ​​the protective cover 255. For example, the protective cover 255 may extend from the top of the second battery 253 to above the interface 254 of the first battery 252. This improves the integration, safety, and stability of the battery module 250.
