[0032] Referring to Figures 1, 2 and 3, Figure 1 shows a schematic structural diagram of a boost compression device 10 in an embodiment of the present application, Figure 2 is a top view of the boost compression device 10 shown in Figure 1, and Figure 3 is a cross-sectional view of the boost compression device 10 shown in Figure 2 at AA.

[0033] As shown in FIG3 , in one embodiment, the present application provides a supercharged compression device 10, which includes a power mechanism 100, a reciprocating assembly 200, a piston 300, a cylinder 400, and a compression mechanism 500. The compression mechanism 500 includes a turbine mechanism 510 and an intake pipe 520. The piston 300 is disposed in the cylinder 400, and the piston 300 has a first compression surface 300a and a second compression surface 300b that are separated from each other. The first compression surface 300a and the inner wall of one side of the cylinder 400 constitute a first working side (not shown), and the second compression surface 300b and the inner wall of the other side of the cylinder 400 constitute a second working side 400b.

[0034] As shown in Figures 3 and 5, the reciprocating assembly 200 includes a reciprocating body 210 and a rolling member 220. The rolling member 220 is embedded in the reciprocating body 210, and the reciprocating body 210 is connected to the piston 300 (it should be noted that in order to clearly show the structural condition that the rolling member 220 is embedded in the reciprocating body 210, the connection condition between the reciprocating body 210 and the piston 300 is omitted in Figure 5. Specifically, the connection condition between the reciprocating body 210 and the piston 300 can be obtained from Figure 3). The power mechanism 100 has an output shaft 130, and the two ends of the output shaft 130 are respectively connected to the shaft head 131 and the turbine mechanism 510. The turbine mechanism 510 is connected to the first working side and the second working side 400b through the intake pipe 520. The shaft head 131 is provided with a guide groove 131a along its circumferential surface, and the rolling element 220 is clamped in the guide groove 131a. The two ends of the output shaft 130 respectively drive the rolling element 220 to move along the guide groove 131a relative to the shaft head 131 and the turbine mechanism 510 to intake and boost pressure. The trajectory of the guide groove 131a is configured as follows: when the shaft head 131 rotates to make the rolling element 220 move along the guide groove 131a, the reciprocating body 210 drives the piston 300 to alternately reciprocate and compress the first working side and the second working side 400b.

[0035] It should be noted that the first working side and the second working side 400b refer to the compression chambers located on both sides of the piston 300. As shown in FIG3 , the piston 300 is completely in contact with the inner wall of one side of the cylinder body 400, and the volume of the first working side is zero, so only the second working side 400b is shown in FIG3 . It can be understood that when the piston 300 is completely in contact with the inner wall of the other side of the cylinder body 400, the volume of the second working side 400b is zero, and the volume of the first working side reaches the maximum.

[0036] The above-mentioned supercharging compression device 10, on the one hand, helps to perform a first-level pre-compression treatment on the high-flow and low-pressure intake gas through the setting of the supercharging mechanism 500, thereby increasing the gas pressure entering the first working side and the second working side 400b for secondary compression, thereby improving the compression effect; on the other hand, the shaft head 131 and the supercharging mechanism 500 are respectively connected at both ends of the output shaft 130, so that the power mechanism 100 can achieve the effect of driving the compression work and intake supercharging at the same time, which helps to optimize the structural layout of the supercharging compression device 10, reduce the size of the device, and improve energy utilization.

[0037] In addition, the above-mentioned supercharged compression device 10 can realize the control of the reciprocating motion of the piston 300 by controlling the rotation of the output shaft 130 through the power mechanism 100. The control method is simple and reliable, and the driving efficiency of the piston 300 is effectively improved. In addition, the piston 300 has a first compression surface 300a and a second compression surface 300b that are separated from each other, so that when the reciprocating body 210 drives the piston 300 to reciprocate, the first compression surface 300a and the second compression surface 300b can compress and work the first working side and the second working side 400b respectively, so that the piston 300 can compress and work whether it is in the process of moving forward or backward, which is helpful to improve the working efficiency of the supercharged compression device 10 and ensure the compression effect.

[0038] It should be noted that the conventional crankshaft rocker compressor, crank connecting rod compressor or swash plate compressor utilizes the reciprocating swing of its eccentric structure to realize the reciprocating motion control of the piston 300. This control method is inefficient and causes great damage to the vibration and friction of the structure. The present application provides a shaft head 131 at the end of the output shaft 130, and utilizes the guide groove 131a of the shaft head 131 to drive the reciprocating motion control method of the piston 300. It abandons the eccentric control method, simplifies the structure, and improves the convenience of control. In addition, compared with the conventional crankshaft rocker compressor, crank connecting rod compressor or swash plate compressor, the present application realizes that the axial direction of the output shaft 130, the movement direction of the reciprocating body 210, and the compression direction of the piston 300 are kept consistent, which helps to reduce the vibration and friction damage between the structures and helps to improve the working reliability of the structure.

[0039] The rolling element 220 may be a spherical ball. When the shaft head 131 rotates, the rolling element 220 moves along the guide groove 131a of the shaft head 131, so the spherical ball of the rolling element 220 can reduce the friction between the rolling element 220 and the wall surface of the guide groove 131a, thereby improving the smoothness of the reciprocating motion of the reciprocating body 210 driven by the shaft head 131.

[0040] As shown in Figure 5, in some embodiments, the trajectory of the guide groove 131a is a closed curve that surrounds the shaft head 131, and the closed curve trajectory of the guide groove 131a has crests a1 and troughs a2, and the crests a1 and the troughs a2 are distributed on the circumferential surface of the shaft head 131 at intervals around the axial direction of the shaft head 131, so that the reciprocating body 210 can reciprocate along the axial direction of the shaft head 131 under the guidance of the crests a1 and the troughs a2.

[0041] Specifically, the number of the peaks a1 and the troughs a2 can be designed according to actual needs. For example, when the rotation speed of the shaft head 131 is constant, the number of the peaks a1 and the troughs a2 can be increased to increase the frequency of the reciprocating motion of the reciprocating body 210, thereby increasing the compression frequency of the piston 300. On the contrary, when the rotation speed of the shaft head 131 is constant, the number of the peaks a1 and the troughs a2 can be reduced to reduce the frequency of the reciprocating motion of the reciprocating body 210, thereby reducing the compression frequency of the piston 300.

[0042] As shown in Figure 5, in some embodiments, the number of peaks a1 and troughs a2 is set to 2, and the peaks a1 and troughs a2 are evenly distributed at 90 degrees around the axis of the shaft head 131. In this way, the reciprocating body 210 can reciprocate twice within one rotation of the shaft head 131, which not only ensures the rationality of the structural arrangement, but also improves the movement efficiency of the reciprocating body 210.

[0043] Continuing with FIG. 1 and FIG. 3 , in some embodiments, the boost compression device 10 further includes a first housing 600 and a second housing 700, and the first housing 600 and the second housing 700 are respectively connected to both sides of the cylinder body 400. The second housing 700 is used to install and protect the reciprocating assembly 200. In this embodiment, the first housing 600 is provided with a first air inlet 610 and a first air outlet 620, and the second housing 700 is provided with a second air inlet 710 and a second air outlet 720, the first air inlet 610 and the first air outlet 620 are connected to the first working side, and the second air inlet 710 and the second air outlet 720 are connected to the second working side 400b, so that independent air inlet and outlet of the first working side and independent air inlet and outlet of the second working side 400b are realized.

[0044] Specifically, the second shell 700 serves as the air inlet and outlet of the second working side 400b on the one hand, and is used to install and protect the reciprocating assembly 200 on the other hand, which helps to improve the structural compactness and structural integrity between the cylinder body 400 and the reciprocating assembly 200, thereby helping to reduce the volume of the boost compression device 10 and improve the portability and applicability of the boost compression device 10.

[0045] As shown in Figure 3, in some embodiments, one end of the intake pipe 520 is connected to the turbine mechanism 510, and the other end of the intake pipe 520 has a first intake connector 521 and a second intake connector 522. The first intake connector 521 is connected to the first air inlet port 610, and the second intake connector 522 is connected to the second air inlet port 710. In this way, high-pressure gas can enter the first working side and the second working side 400b respectively, thereby ensuring working reliability.

[0046] Specifically, the turbine mechanism 510 is arranged at the rear of the supercharged compression device 10 as a whole, and the turbine mechanism 510 is drivingly connected to the end of the output shaft 130, thereby achieving the effect of simultaneously outputting torque at both ends of the output shaft 130, which helps to improve the driving utilization rate of the power mechanism 100; in addition, the intake pipe 520 is arranged at the bottom of the supercharged compression device 10 as a whole to connect the turbine mechanism 510 and the intake port of the cylinder body 400, thereby avoiding an increase in the size of the device in the length direction, which helps to improve the structural compactness of the supercharged compression device 10.

[0047] For ease of understanding, the following describes the air intake and exhaust processes of the boost compression device 10 shown in FIG. 3 .

[0048] Since in the boost compression device 10 of the present application, the reciprocating body 210 can drive the piston 300 to alternately reciprocate and compress the first working side and the second working side 400b, the reciprocating motion of the piston 300 in the cylinder body 400 includes a process in which the first compression surface 300a compresses the left inner wall of the cylinder body 400, and a process in which the second compression surface 300b compresses the right inner wall of the cylinder body 400.

[0049] Specifically, from the perspective shown in FIG. 3 , when the piston 300 starts to compress rightward from the leftmost side of the cylinder 400 (the first compression surface 300a abuts the left inner wall of the cylinder 400), the second air inlet 710 and the second air outlet 720 both remain in a closed state, and the gas in the second working side 400b is compressed as the piston 300 moves. As the piston 300 continues to compress rightward, the gas pressure in the second working side 400b gradually increases, and the gas is eventually discharged through the second air outlet 720. In addition, during this process, the first air outlet 620 remains in a closed state, and the first air inlet 610 remains in an open state, and the compressed gas flows into the first working side through the first air inlet 610. When the second compression surface 300b of the piston 300 abuts the rightmost inner wall of the cylinder 400, the compression and working process of the second working side ends, and the piston 300 starts to move to the left and compresses and works on the first working side 400a.

[0050] When the piston 300 starts to compress to the left from the rightmost side of the cylinder 400 (the second compression surface 300b abuts against the right inner wall of the cylinder 400), the first air inlet 610 and the first air outlet 620 are both kept closed, and the gas in the first working side is compressed as the piston 300 moves. As the piston 300 continues to compress to the left, the gas pressure in the first working side gradually increases, and the gas is eventually discharged through the first air outlet 620. In addition, during this process, the second air outlet 720 is kept closed, and the second air inlet 710 is kept open, and the compressed gas flows into the second working side 400b through the second air inlet 710.

[0051] The above is a general process of the air inlet and outlet of the boost compression device 10 . This process can realize the bidirectional compression of the piston 300 , which helps to improve the compression effect of the boost compression device 10 .

[0052] As shown in FIG. 3 , in some embodiments, the boost compression device 10 further includes a first valve plate 800 and a second valve plate 900. The first valve plate 800 is sandwiched between the first housing 600 and the cylinder body 400, and the second valve plate 900 is sandwiched between the second housing 700 and the cylinder body 400. The first valve plate 800 is provided with a first air intake valve 810 and a first air outlet valve 820, respectively. The first air intake port 610 is connected to the first working side through the first air intake valve 810, and the first air outlet port 620 is connected to the first working side through the first air outlet valve 820. The second valve plate 900 is provided with a second air intake valve 910 and a second air outlet valve 920, respectively. The second air intake port 710 is connected to the second working side 400b through the second air intake valve 910, and the second air outlet port 720 is connected to the second working side 400b through the second air outlet valve 920.

[0053] Specifically, the first valve plate 800 is opposite to the first compression surface 300a, and the second valve plate 900 is opposite to the second compression surface 300b. The first valve plate 800 and the second valve plate 900 serve as mounting carriers for the inlet and outlet valve bodies, and also serve as sealing members between the housing and the cylinder body 400. Therefore, in some embodiments, first sealing members are provided on both sides of the first valve plate 800, and second sealing members 930 are provided on both sides of the second valve plate 900, which helps to improve the sealing performance of the boost compression device 10 and ensure the reliability of the compression of the piston 300.

[0054] As shown in FIG4 , in some embodiments, the second valve plate 900 is provided with a second air inlet 900a and a second air outlet 900b, and the second air inlet valve 910 and the second air outlet valve 920 can be connected to the second air inlet 900a and the second air outlet 900b, respectively. In addition, as shown in FIG4 , the second valve plate 900 is further provided with a second sealing member 930, which is beneficial to improve the air inlet and outlet sealing effect of the second valve plate 900, thereby ensuring the compression effect of the boost compression device 10.

[0055] Similarly, the first valve plate 800 is provided with a first air inlet hole and a first air outlet hole, and the first air inlet valve 810 and the first air outlet valve 820 can be connected to the first air inlet hole and the first air outlet hole respectively. In addition, the first valve plate 800 is also provided with a first sealing member, which is beneficial to improve the sealing effect of the air inlet and outlet of the first valve plate 800, thereby ensuring the compression effect of the gas.

[0056] As shown in combination with FIG. 4 and FIG. 5 , in some embodiments, the reciprocating body 210 includes a connecting body 211 and a nesting 212, and the rolling element 220 is embedded in the nesting 212. In addition, as shown in combination with FIG. 3 to FIG. 5 , the connecting body 211 is provided with a locking structure 2111, and the booster compression device 10 also includes a connecting shaft 1100, the connecting shaft 1100 is connected to the piston 300, and the end of the connecting shaft 1100 away from the piston 300 is provided with a connecting disk 1110, and the connecting disk 1110 is fixed to the locking structure 2111.

[0057] Specifically, the connecting body 211 and the nesting 212 can be integrally formed or bolted. The axis of the connecting shaft 1100 is consistent with the movement direction of the connecting body 211, which helps to ensure the smoothness of the movement of the piston 300. In addition, the design of providing a connecting plate 1110 at one end of the connecting shaft 1100 helps to improve the connection stability between the connecting shaft 1100 and the connecting body 211, and improve the working reliability of the supercharged compression device 10.

[0058] As shown in FIG. 4 , in some embodiments, the connector 211 is provided with a perforated structure 2112 , and the reciprocating assembly 200 further includes a guide rod assembly 230 , and the guide rod assembly 230 is provided through the perforated structure 2112 .

[0059] Specifically, the guide rod assembly 230 may include a first guide rod and a second guide rod that are inserted into both sides of the connecting body 211, which helps to improve the stability of the reciprocating motion of the reciprocating body 210. Understandably, in other embodiments, the guide rod assembly 230 may also include a third guide rod, a fourth guide rod, etc. The number of guide rods can be designed according to actual structural requirements. Specifically, a plurality of guide rods can be evenly distributed around the axis of the output shaft 130.

[0060] Continuing to refer to FIG. 4 , in some embodiments, the boost compression device 10 further includes a third housing 1000, and the guide rod assembly 230 includes a first guide rod and a second guide rod that are inserted through both sides of the connecting body 211. The first guide rod is fixedly connected to the second housing 700 and the third housing 1000, respectively, and both ends of the second guide rod are fixedly connected to the second housing 700 and the third housing 1000, respectively.

[0061] As shown in FIG6 , in some embodiments, the power mechanism 100 further includes a first rolling bearing 140 and a second rolling bearing 150, which are sleeved on the output shaft 130 at intervals, respectively, so as to help reduce the rotational friction resistance of the output shaft 130. In addition, the power mechanism 100 further includes a first plane bearing 160 and a second plane bearing 170, which are sleeved on the middle part of the output shaft 130 at intervals, so as to help improve the bearing capacity of the output shaft 130.

[0062] As shown in Figure 7, in some embodiments, the power mechanism 100 also includes a motor 110 and a reduction mechanism 120, the reduction mechanism 120 is connected to the motor 110, one end of the output shaft 130 is connected to the reduction mechanism 120, and the other end is connected to the reciprocating component 200. The reduction mechanism 120 is used to decelerate and increase the torque of the motor 110, and transmit the torque to the reciprocating component 200 via the output shaft 130, thereby achieving reasonable transmission of torque.

[0063] Specifically, in this embodiment, the present application can directly drive the rotation of the output shaft 130 through the motor 110 to realize the reciprocating motion of the piston 300. Compared with the control of the traditional eccentric structure, the control method of the present application is more convenient. The installation can be completed by connecting the output end of the motor 110 to the output shaft 130, thereby improving the assembly simplicity of the boost compression device 10 and the connection reliability of the structure.

[0064] Continuing with FIG. 7 , the reduction mechanism 120 is a planetary gear structure, and the end of the output shaft 130 has a disc-shaped structure with corresponding connecting holes formed therein. The planetary gear structure is inserted into the corresponding connecting holes to achieve a fixed connection between the connecting shaft 1100 and the planetary gear structure.

[0065] In some embodiments, as shown in FIG1 , in some embodiments, the supercharged compression device 10 further includes a heat dissipation mechanism 1200, which is wrapped around the outer surface of the cylinder 400, thereby improving the heat dissipation effect of the cylinder 400. Specifically, the heat dissipation mechanism 1200 may be composed of a plurality of heat dissipation fins, thereby being able to discharge the heat of the cylinder 400 in a timely manner.

[0066] As shown in FIG8 , in some embodiments, the boost compression device 10 is further provided with a high-speed motor 1300, and the high-speed motor 1300 is drivingly connected to the turbine mechanism 510. Specifically, this embodiment is different from the above-mentioned embodiment in which the two ends of the output shaft 130 are respectively connected to the shaft head 131 and the turbine mechanism 510. In this embodiment, the turbine mechanism 510 can be controlled by a separate high-speed motor 1300, and the reciprocating motion of the piston 300 is controlled by a separate power mechanism 100, so that the first-stage compression drive structure and the second-stage compression drive structure are arranged independently of each other, which helps to reduce mutual interference when a fault occurs and improve the working reliability of the device. It should be noted that in actual applications, the present application scheme can be targeted to select whether to add a high-speed motor 1300 according to actual needs.

[0067] Further, in conjunction with FIG9 , in some embodiments, the turbocharged compression device 10 has two turbine mechanisms 510, and is further provided with a primary pipeline 530 and a secondary pipeline 540. The high-speed motor 1300 has two output ends, and the two output ends are respectively connected to the two turbine mechanisms 510, wherein the air outlet end of one turbine mechanism 510 is connected to the air inlet end of the other turbine mechanism 510 through the primary pipeline 530, and the air outlet end of the other turbine mechanism 510 is connected to the first air inlet 610 and the second air inlet 710, so that a three-stage compression effect can be achieved.

[0068] Specifically, as shown in FIG9 , one of the turbine mechanisms 510 is used to perform a first-stage compression on the gas, and then the first-stage compressed gas is passed into another turbine mechanism 510 through a first-stage pipeline 530, and the other turbine mechanism 510 is used to perform a second-stage compression on the gas, and finally the gas is passed into the cylinder 400 for a third-stage compression and output. It can be understood that the turbine mechanism 510 is used to pre-compress the gas, and the number of turbine mechanisms 510 used for pre-compression can be set according to actual needs, and only corresponding pipelines and high-speed motors 1300 need to be added.

[0069] In addition, in the above three-stage compression embodiment, two turbine mechanisms 510 are connected to the two ends of the high-speed motor 1300, respectively, so that one driving mechanism drives two compression mechanisms to operate, which helps to reduce energy consumption and reduce the overall volume of the device. It should be noted that in actual applications, the present application solution can be targeted to select whether to add a high-speed motor 1300 according to actual needs.

[0070] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0071] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
