Description

Technical Field

[0001] This disclosure pertains to the field of hydraulic devices, and particularly relates to a hydraulic cylinder device. Background Technology

[0002] A hydraulic cylinder is a common hydraulic actuator that converts hydraulic energy into mechanical energy to output driving force.

[0003] In related technologies, common hydraulic cylinder devices mainly include a cylinder body and a piston rod. One end of the piston rod is movably inserted into the cylinder body, while the other end is located outside the cylinder body. By outputting hydraulic oil into the cylinder body, the piston rod can be driven to move in a linear direction, thereby outputting a driving force in that linear direction.

[0004] However, there are some special application scenarios where space is relatively confined and driving force in multiple directions is required. The hydraulic cylinder devices in related technologies cannot meet the needs of driving force in multiple directions, and if multiple cylinders are used, they are not suitable for confined spaces.

[0043] To make the objectives, technical solutions, and advantages of this disclosure clearer, the embodiments of this disclosure will be described in further detail below with reference to the accompanying drawings.

[0044] Figure 1 See the schematic diagram of the hydraulic cylinder device provided in the embodiments of this disclosure. Figure 1In this embodiment, the hydraulic cylinder device includes a cylinder body 10, and a transverse piston rod 20, a longitudinal piston rod 30, a first lateral piston rod 40, and a second lateral piston rod 50 movably inserted into the cylinder body 10.

[0045] The cylinder block 10 has a first oil port 110 and a second oil port 120. The lateral piston rod 20 moves in a first direction a, the longitudinal piston rod 30 moves in a second direction b, and the first lateral piston rod 40 and the second lateral piston rod 50 move in a third direction c. There are angles between the first direction a, the second direction b, and the third direction c. When oil enters one of the first oil port 110 and the second oil port 120, and oil exits from the other of the first oil port 110 and the second oil port 120, the lateral piston rod 20, the longitudinal piston rod 30, the first lateral piston rod 40, and the second lateral piston rod 50 all move relative to the cylinder block 10.

[0046] The hydraulic cylinder device provided in this embodiment includes a transverse piston rod 20, a longitudinal piston rod 30, a first lateral piston rod 40, and a second lateral piston rod 50. The transverse piston rod 20 moves in a first direction a, the longitudinal piston rod 30 moves in a second direction b, and the first lateral piston rod 40 and the second lateral piston rod 50 move in a third direction c. An angle is formed between each of the first direction a, the second direction b, and the third direction c. Therefore, the hydraulic cylinder device can output driving force in three directions. Furthermore, since the transverse piston rod 20, the longitudinal piston rod 30, the first lateral piston rod 40, and the second lateral piston rod 50 share the same cylinder body 10, installation space is effectively saved, allowing the hydraulic cylinder device to be installed and used in relatively confined spaces.

[0047] In other words, the hydraulic cylinder device provided in this embodiment can not only be used in confined spaces, but also output driving force in multiple directions, making it suitable for application scenarios where driving force in multiple directions is output in confined spaces.

[0048] In this embodiment, the first direction a, the second direction b, and the third direction c are perpendicular to each other, that is, the angle between the first direction a, the second direction b, and the third direction c is a right angle. In other embodiments, the angle between the first direction a, the second direction b, and the third direction c can also be adjusted according to actual needs, and this disclosure does not impose any restrictions on this.

[0049] See also Figure 1 In this embodiment, the cylinder body 10 includes a transverse section 130, a longitudinal section 140, and a lateral section 150. One end of the transverse section 130 is connected to the lateral section 150, and the other end of the transverse section 130 is connected to the longitudinal section 140.

[0050] The transverse piston rod 20 is movably inserted into the transverse section 130, the longitudinal piston rod 30 is movably inserted into the longitudinal section 140, the first lateral piston rod 40 is movably inserted into one end of the lateral section 150, and the second lateral piston rod 50 is movably inserted into the other end of the lateral section 150.

[0051] In the above implementation, the transverse section 130 serves as the mounting base for the transverse piston rod 20, the longitudinal section 140 serves as the mounting base for the longitudinal piston rod 30, and the lateral section 150 serves as the mounting base for the first lateral piston rod 40 and the second lateral piston rod 50.

[0052] For example, the length direction of the transverse segment 130 is a first direction a, the length direction of the longitudinal segment 140 is a second direction b, and the length direction of the lateral segment 150 is a third direction c.

[0053] This design ensures that the length direction of the transverse segment 130 is consistent with the movement direction of the transverse piston rod 20, the length direction of the longitudinal segment 140 is consistent with the movement direction of the lateral piston rod, and the length direction of the lateral segment 150 is consistent with the movement direction of the first lateral piston rod 40 and the second lateral piston rod 50.

[0054] For example, the first end of the transverse segment 130 is connected to the middle of the lateral segment 150, and the second end of the transverse segment 130 is connected to the end of the longitudinal segment 140.

[0055] In the above implementation, the transverse segment 130, longitudinal segment 140, and lateral segment 150 are arranged in a reasonable manner, ensuring that they do not interfere with each other and that the structure is compact. Furthermore, this also facilitates the arrangement of the transverse piston rod 20, longitudinal piston rod 30, first lateral piston rod 40, and second lateral piston rod 50, ensuring that they do not interfere with each other.

[0056] For example, the transverse section 130, the longitudinal section 140, and the lateral section 150 are integral structural components. This ensures the structural integrity and sealing performance of the cylinder body 10, while also improving the manufacturing efficiency of the cylinder body 10.

[0057] In this embodiment, the transverse piston rod 20 is a double-ended piston rod, with one end of the transverse piston rod 20 located outside one end of the transverse section 130 and the other end of the transverse piston rod 20 located outside the other end of the transverse section 130.

[0058] In the above implementation, a double-ended piston rod refers to a piston and two rods, with the two rods located on opposite sides of the piston. As the piston moves, it drives the two rods to move together, allowing the transverse piston rod 20 to output driving force in both directions simultaneously.

[0059] In this embodiment, the longitudinal piston rod 30, the first lateral piston rod 40, and the second lateral piston rod 50 are single-headed piston rods.

[0060] In the above implementation, a single-headed piston rod refers to a piston rod and a connecting rod, with the connecting rod located on one side of the piston. As the piston moves, it drives the connecting rod to move, thus outputting a driving force in one direction.

[0061] This design is intended to avoid interference and collision between the longitudinal piston rod 30, the first lateral piston rod 40, the second lateral piston rod 50, and the transverse piston rod 20, effectively improving the reliability of the hydraulic cylinder device.

[0062] Figure 2 for Figure 1 A sectional view along the AA direction, combined with Figure 2 In this embodiment, the piston of the transverse piston rod 20 divides the internal space of the transverse section 130 into a first transverse cavity 131 and a second transverse cavity 132.

[0063] In the above implementation, the first transverse cavity 131 is close to the lateral segment 150, and the second transverse cavity 132 is close to the longitudinal segment 140.

[0064] In this embodiment, the piston of the longitudinal piston rod 30 divides the internal space of the longitudinal section 140 into a first longitudinal cavity 141 and a second longitudinal cavity 142.

[0065] In the above implementation, the first longitudinal cavity 141 is far away from the transverse segment 130, and the second longitudinal cavity 142 is close to the transverse segment 130.

[0066] Figure 3 for Figure 1 BB direction sectional view, combined with Figure 3 In this embodiment, the piston of the first lateral piston rod 40 and the piston of the second lateral piston rod 50 divide the internal space of the lateral segment 150 into a first lateral cavity 151, a second lateral cavity 152, a third lateral cavity 153 and a fourth lateral cavity 154.

[0067] In the above implementation, the first lateral cavity 151, the second lateral cavity 152, the third lateral cavity 153 and the fourth lateral cavity 154 are arranged sequentially at intervals along the length of the lateral segment 150. The first lateral cavity 151 and the second lateral cavity 152 are located on one side of the first transverse cavity 131, and the third lateral cavity 153 and the fourth lateral cavity 154 are located on the other side of the first transverse cavity 131.

[0068] See Figure 2 and Figure 3 The first oil port 110, the first transverse cavity 131, the second lateral cavity 152 and the third lateral cavity 153 are connected. Figure 4 for Figure 1 The CC-direction sectional view, combined with Figure 4 The first transverse cavity 131 and the first longitudinal cavity 141 are connected. In summary, the first oil port 110, the first transverse cavity 131, the first longitudinal cavity 141, the second lateral cavity 152, and the third lateral cavity 153 are interconnected.

[0069] See Figure 2 The first oil port 110, the second transverse cavity 132, and the second longitudinal cavity 142 are connected. Figure 5 for Figure 1 DD-direction sectional view, combined with Figure 5 The second oil port 120, the first lateral cavity 151, and the fourth lateral cavity 154 are connected. In summary, the second oil port 120, the second transverse cavity 132, the second longitudinal cavity 142, the first lateral cavity 151, and the fourth lateral cavity 154 are interconnected.

[0070] When oil enters through the first port 110, high-pressure hydraulic oil flows into the first transverse cavity 131, the first longitudinal cavity 141, the second lateral cavity 152, and the third lateral cavity 153, causing the transverse piston rod 20 to extend near the longitudinal section 140, the longitudinal piston rod 30 to retract, and the first lateral piston rod 40 and the second lateral piston rod 50 to extend. Simultaneously, low-pressure hydraulic oil in the second transverse cavity 132, the second longitudinal cavity 142, the first lateral cavity 151, and the fourth lateral cavity 154 flows back through the second port 120.

[0071] When oil enters through the second port 120, high-pressure hydraulic oil flows into the second transverse cavity 132, the second longitudinal cavity 142, the first lateral cavity 151, and the fourth lateral cavity 154, causing the transverse piston rod 20 to extend near the lateral section 150, the longitudinal piston rod 30 to extend, and the first lateral piston rod 40 and the second lateral piston rod 50 to retract. Simultaneously, low-pressure hydraulic oil in the first transverse cavity 131, the first longitudinal cavity 141, the second lateral cavity 152, and the third lateral cavity 153 flows back through the first port 110.

[0072] Combination Figure 2 and Figure 4 In this embodiment, the transverse segment 130 has a first oil passage 133, the length direction of the first oil passage 133 is consistent with the length direction of the transverse segment 130, and the first end of the first oil passage 133 is connected to the first transverse cavity 131. The longitudinal segment 140 has a second oil passage 143, the length direction of the second oil passage 143 is consistent with the length direction of the longitudinal segment 140, the first end of the second oil passage 143 is connected to the second end of the first oil passage 133, and the second end of the second oil passage 143 is connected to the first longitudinal cavity 141.

[0073] In the above implementation, the first transverse cavity 131 and the first longitudinal cavity 141 can be connected through the first oil passage 133 and the second oil passage 143. Furthermore, since the length direction of the first oil passage 133 is consistent with the length direction of the transverse segment 130, the first oil passage 133 will not interfere with the transverse piston rod 20. Similarly, since the length direction of the second oil passage 143 is consistent with the length direction of the longitudinal segment 140, the second oil passage 143 will not interfere with the longitudinal piston rod 30.

[0074] Combination Figure 5 In this embodiment, the lateral segment 150 has a third oil passage 155 and a fourth oil passage 156. The length direction of the third oil passage 155 and the length direction of the fourth oil passage 156 are both consistent with the length direction of the lateral segment 150. The first end of the third oil passage 155 is connected to the first lateral cavity 151, the first end of the fourth oil passage 156 is connected to the fourth lateral cavity 154, and the second ends of the third oil passage 155 and the fourth oil passage 156 are respectively connected to the second oil port 120.

[0075] In the above implementation, the third oil passage 155 enables communication between the first lateral cavity 151 and the second oil port 120, and the fourth oil passage 156 enables communication between the second lateral cavity 152 and the second oil port 120. Furthermore, since the length directions of both the third oil passage 155 and the fourth oil passage 156 are consistent with the length direction of the lateral segment 150, they will not interfere with the first lateral piston rod 40 and the second lateral piston rod 50.

[0076] Combination Figure 2 and Figure 5 In this embodiment, the transverse segment 130 has a fifth oil passage 134. The length direction of the fifth oil passage 134 is consistent with the length direction of the transverse segment 130. The first end of the fifth oil passage 134 is connected to the second transverse cavity 132 and the second longitudinal cavity 142 respectively, and the second end of the fifth oil passage 134 is connected to the second oil port 120.

[0077] In the above implementation, the fifth oil passage 134 enables communication between the second transverse cavity 132 and the second oil port 120. Furthermore, since the length direction of the fifth oil passage 134 is consistent with the length direction of the transverse cavity, the fifth oil passage 134 will not interfere with the transverse piston rod 20.

[0078] Combination Figure 2 In this embodiment, the inner wall of the first transverse cavity 131 has a transverse limiting flange 135, which is located in the part of the first transverse cavity 131 that is far away from the second transverse cavity 132.

[0079] In the above implementation, the lateral limiting flange 135 is used to limit the travel of the lateral piston rod 20. By adjusting the position of the lateral limiting flange 135, the travel of the lateral piston rod 20 can be adjusted.

[0080] It is worth noting that, because the transverse segment 130 needs to connect the longitudinal segment 140 and the lateral segment 150 respectively, the length of the transverse segment 130 is limited, making it inconvenient to directly adjust the travel of the transverse piston rod 20 by adjusting the length of the transverse segment 130. Therefore, it is necessary to adjust the travel of the transverse piston rod 20 by adjusting the position of the transverse limiting flange 135.

[0081] Continue to combine Figure 2 In this embodiment, the inner wall of the second longitudinal cavity 142 has a longitudinal limiting flange 144, which is located in the part of the second longitudinal cavity 142 away from the first longitudinal cavity 141.

[0082] In the above implementation, the longitudinal limiting flange 144 is used to limit the travel of the longitudinal piston rod 30, effectively avoiding interference and collision between the longitudinal piston rod 30 and the transverse piston rod 20.

[0083] Combination Figure 3 In this embodiment, the inner walls of the second lateral cavity 152 and the third lateral cavity 153 both have lateral limiting flanges 157. The lateral limiting flanges 157 of the second lateral cavity 152 are located away from the first lateral cavity 151, and the lateral limiting flanges 157 of the third lateral cavity 153 are located away from the fourth lateral cavity 154.

[0084] In the above implementation, the lateral limiting flange 157 is used to limit the travel of the first lateral piston rod 40 and the second lateral piston rod 50, effectively avoiding interference and collision between the first lateral piston rod 40 and the second lateral piston rod 50 and the transverse piston rod 20.

[0085] The following is a brief introduction to the working principle of the hydraulic cylinder device:

[0086] When oil enters through the first port 110, high-pressure hydraulic oil flows through the first transverse cavity 131, causing the transverse piston rod 20 to extend near the longitudinal section 140. Simultaneously, high-pressure hydraulic oil flows through the first transverse cavity 131, the first oil passage 133, the second oil passage 143, and the first longitudinal cavity 141, causing the longitudinal piston rod 30 to retract. Simultaneously, high-pressure hydraulic oil flows through the first transverse cavity 131, the second lateral cavity 152, and the third lateral cavity 153, causing the first lateral piston rod 40 and the second lateral piston rod 50 to extend. For low-pressure hydraulic oil, the hydraulic oil in the second transverse cavity 132 flows out of the second port 120 via the fifth oil passage 134. Simultaneously, the hydraulic oil in the second longitudinal cavity 142 flows out of the second port 120 via the fifth oil passage 134. Simultaneously, the hydraulic oil in the first lateral cavity 151 and the fourth lateral cavity 154 flows out of the second port 120 via the third oil passage 155 and the fourth oil passage 156, respectively.

[0087] The flow paths of high-pressure and low-pressure hydraulic oil when oil enters through the second oil port 120, as well as the movements of the transverse piston rod 20, longitudinal piston rod 30, first lateral piston rod 40, and second lateral piston rod 50, are the opposite of those described above when oil enters through the first oil port 110, and will not be repeated here.
