Description

Technical Field

[0001] This invention belongs to the field of demonstration equipment technology, specifically relating to a hydraulic training platform for automotive steering systems. Background Technology

[0002] A hydraulic training platform is a teaching device that integrates real industrial components such as hydraulic pumps, hydraulic cylinders, control valves, pipelines and instruments, and combines them with electrical control and PLC modules for practical training and experiments in hydraulic transmission courses.

[0003] Currently, some vehicles use hydraulic power steering. By connecting the hydraulic power steering device of the steering system to the hydraulic training platform, the actual working conditions of the steering system can be simulated.

[0004] During their experiments, the inventors discovered that current hydraulic training platforms have a problem: vehicle steering systems typically include components such as steering gears, tie rods, and steering linkages. The integration of these components results in a large overall size for the steering system. However, the limited surface area of ​​current hydraulic training platforms makes it difficult to fully accommodate the steering system, hindering its secure mounting. Furthermore, some hydraulic training platforms have externally mounted hydraulic pumps and accessories, usually installed on one side of the platform. This external pump design also obstructs the handling and securing of the steering system.

[0005] In summary, how to fix the steering system to the hydraulic training platform when the placement area is limited is a technical problem that needs to be solved. Summary of the Invention

[0006] Based on the problems existing in the prior art, the purpose of this invention is to provide a hydraulic training platform for automotive steering systems, which can increase the stability and reliability of automotive steering systems.

[0007] To achieve the aforementioned objectives, the technical solution adopted by this invention is as follows: This application provides a hydraulic training platform for an automotive steering system, comprising a main body with an insertion channel, and an extension assembly. The extension assembly includes an extension section, two cantilever arms, and two fixing components. The extension section has an insertion section inserted into the insertion channel. The cantilever arms are rotatably connected to the extension section, and the two cantilever arms are spaced apart along the length of the extension section. The two fixing components are rotatably mounted on the two cantilever arms in a one-to-one correspondence, and are used to clamp the automotive steering system.

[0008] In some embodiments, the insertion channel is provided with a plurality of through holes at intervals along the axial direction of the insertion channel, and the insertion part is provided with a pin hole corresponding to the through hole. The expansion component also includes a pin, which is selectively inserted into one of the plurality of through holes and inserted into the pin hole.

[0009] In some embodiments, insertion portions are provided on both sides of the extension portion along its length.

[0010] In some embodiments, along the axial direction of the insertion channel, the insertion portion protrudes from both sides of the extension portion, and is cantilevered and rotatably connected to the end of the insertion portion away from the insertion channel.

[0011] In some embodiments, the fixing component includes a mounting portion, a support portion, and a mating arm. The mounting portion is rotatably connected to the cantilever, and the support portion is connected to the mounting portion via a connecting portion. The mounting portion and the support portion are spaced apart. The mating arm is disposed between the support portion and the mounting portion. The mating arm includes a first portion and a second portion, which are bent. The bent portion of the mating arm is rotatably connected to the mounting portion. The rotation axis of the mating arm is parallel to the rotation axis of the mounting portion. The end of the first portion abuts against the support portion. The support portion is provided with a limiting groove, and the end of the first portion is accommodated in the limiting groove. The first portion is configured to include a first state and a second state. In the first state, the first portion can deform, and in the second state, the first portion cannot deform.

[0012] In some embodiments, the first part includes a plurality of unit bodies and a resilient insertion portion. The plurality of unit bodies are connected sequentially, with the end unit bodies connected to the second part. Between two adjacent unit bodies, one is provided with a shaft, and the other with a shaft hole and a limiting portion. The shaft passes through the shaft hole, and the limiting portion is movably connected to the unit body along the radial direction of the shaft. The shaft includes a limiting segment with a polygonal cross-section, and the limiting portion has a limiting cavity in which the limiting segment is engaged. Each unit body has a slot, the extension direction of which is perpendicular to the axial direction of the shaft. The resilient insertion portion passes sequentially through the slots of the plurality of unit bodies, and abuts against the side of the limiting portion away from the shaft.

[0013] In some embodiments, the support portion is provided with a clearance notch, which is used to avoid the resilient insertion portion.

[0014] In some embodiments, an elastic element is provided between the limiting part and the unit body.

[0015] In some embodiments, a limiting shaft is provided at one end of the elastic insertion part away from the bend of the mating arm, and a locking through groove is provided at the bend of the mating arm. The locking through groove is arc-shaped, and an opening is provided on the side of the locking through groove near the second part.

[0016] In some embodiments, the second part includes a first arm, a second arm, and an elastic movable sleeve. The first arm is connected to the first part, and the second arm is rotatably connected to the first arm. The first and second arms form a bent structure. A first support roller is provided at the connection between the first arm and the first part, a second support roller is provided at the connection between the first and second arms, and a third support roller is provided at the end of the second arm away from the first arm. The elastic movable sleeve is sleeved on the first, second, and third support rollers.

[0017] The present invention has the following beneficial effects:

[0018] 1. When the insertion part is inserted into the insertion channel, the extension part and the main body together form a placement surface, providing a larger operating space for fixing the steering system, making the fixing of the steering system more convenient and reliable. At the same time, the larger placement surface can increase the support stability of the steering system, thereby improving the reliability of fixing the steering system.

[0019] 2. By extending the component to move the steering system, the manual handling process is eliminated, making it easier and faster to fix the steering system.

[0020] 3. Due to the increased placement area, components outside the main body can be avoided when fixing the steering system, so that these components will not obstruct the fixing of the steering system, thereby improving the fixing reliability of the steering system.

[0021] 4. By using fixed components, the reliability of the steering system can be improved, and the steering system can be smoothly transported to the test position. Attached Figure Description

Detailed Implementation

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Unless otherwise specified, the technical means used in the embodiments are conventional means well known to those skilled in the art.

[0031] In the description of this invention, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this invention, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention.

[0032] See Figure 1 This application provides a hydraulic training platform for an automotive steering system, including a main body 1 with an insertion channel 11, and an extension component 2. The extension component 2 includes an extension section 21, two cantilever arms 23, and two fixing components 24. The extension section 21 has an insertion section 22 inserted into the insertion channel 11. The cantilever arms 23 are rotatably connected to the extension section 21, and the two cantilever arms 23 are spaced apart along the length of the extension section 21. The two fixing components 24 are rotatably mounted on the two cantilever arms 23 in a one-to-one correspondence, and the fixing components 24 are used to clamp the automotive steering system 3.

[0033] The length direction of the extension section 21 can be Figure 1 The direction indicated by the X-axis.

[0034] The structure, components, and working principle of the hydraulic training platform are well-known to those skilled in the art and will not be described in detail here.

[0035] The insertion channel 11 can be detachably connected to the body 1. For example, the insertion channel 11 can be connected to the body 1 by bolts, which facilitates the upgrading and transformation of the existing hydraulic training platform.

[0036] When the insertion part 22 is inserted into the insertion channel 11, the top surface of the extension part 21 can be flush with the placement surface of the main body 1. The extension part 21 and the main body 1 together form a placement surface, providing a larger operating space for fixing the steering system 3, making the fixing of the steering system 3 more convenient and reliable. At the same time, the larger placement surface can increase the support stability of the steering system 3, thereby improving the fixing reliability of the steering system 3.

[0037] The drive structure of the cantilever 23 can be selected from existing structures, such as a combination of a motor and a reducer, which will not be elaborated here.

[0038] Initially, the cantilever 23 can rotate to its end facing downwards, at which point the fixed component 24 is at its lowest point, allowing the steering system 3 to be clamped by the fixed component 24. Subsequently, the cantilever 23 rotates, causing the fixed component 24 to move upwards. In this embodiment, the initial rotation direction of the cantilever 23 can be a rotation away from the body 1, so as to... Figure 1 As shown in the example, the cantilever 23 first rotates counterclockwise until it reaches its highest point, and then gradually falls down, so that the fixed component 24 can move the steering system 3 above the placement surface of the body 1.

[0039] The advantage of this arrangement is that the cantilever 23 carries the steering system 3 away from the main body 1, reducing the risk that components outside the main body 1, such as the hydraulic pump and its accessories, will obstruct the movement of the steering system 3. Secondly, due to the increased placement area, components outside the main body 1 can be avoided when fixing the steering system 3, ensuring that these components will not obstruct the fixing of the steering system 3, thereby improving the reliability of fixing the steering system 3.

[0040] The two ends of the steering system 3 can be fixed by two fixed parts 24 respectively, and can be moved by two cantilever arms 23, which can improve the handling stability of the steering system 3.

[0041] By moving the steering system 3 using the extension component 2, the manual handling process is eliminated, making it easier and faster to fix the steering system 3.

[0042] The main body 1 may be provided with a positioning block 12 with a positioning recess for positioning the steering system 3.

[0043] See Figure 2 In some embodiments, the insertion channel 11 is provided with a plurality of through holes 111 at intervals along the axial direction of the insertion channel 11, and the insertion part 22 is provided with a pin hole corresponding to the through hole 111. The expansion component 2 also includes a pin, which is selectively inserted into one of the plurality of through holes 111 and inserted into the pin hole.

[0044] When the pin passes through the through hole 111 and is inserted into the pin hole, the position of the insertion part 22 in the insertion channel 11 can be fixed, reducing the risk of the insertion part 22 coming out of the insertion channel 11.

[0045] See Figure 1 In some embodiments, insertion portions 22 are provided on both sides of the extension portion 21 along the length direction of the extension portion 21.

[0046] By providing insertion parts 22 on both sides of the extension part 21, the fitting accuracy between the extension part 21 and the main body is increased.

[0047] See Figure 1 In some embodiments, along the axial direction of the insertion channel 11, the insertion part 22 protrudes from both sides of the extension part 21, and the cantilever 23 is rotatably connected to the end of the insertion part 22 away from the insertion channel 11.

[0048] That is, along the axial direction of the insertion channel 11, the length of the insertion part 22 is greater than the size of the extension part 21, so that the two ends of the insertion part 22 can protrude from both sides of the extension part 21.

[0049] The cantilever 23 is rotatably connected to the end of the insertion part 22 away from the insertion channel 11. The advantage of this arrangement is that, on the one hand, in the initial state, the cantilever 23 can be kept as far away as possible from the components outside the mounting body 1, reducing the risk that these components will obstruct the movement of the steering system 3. On the other hand, it provides room for the cantilever 23 to rotate from top to bottom and place the steering system 3 on the mounting surface.

[0050] See Figure 3 , Figure 4 and Figure 5In some embodiments, the fixing component 24 includes a mounting portion 241, a support portion 243, and a mating arm. The mounting portion 241 is rotatably connected to the cantilever 23, and the support portion 243 is connected to the mounting portion 241 via a connecting portion 242. The mounting portion 241 and the support portion 243 are spaced apart. The mating arm is disposed between the support portion 243 and the mounting portion 241. The mating arm includes a first part 244 and a second part, which are bent. The bent portion of the mating arm is rotatably connected to the mounting portion 241. The rotation axis of the mating arm is parallel to the rotation axis of the mounting portion 241. The end of the first part 244 abuts against the support portion 243. The support portion 243 is provided with a limiting groove 249, and the end of the first part 244 is accommodated in the limiting groove 249. The first part 244 is configured to include a first state and a second state. In the first state, the first part 244 can deform, and in the second state, the first part 244 cannot deform.

[0051] Mounting part 241 is rotatably connected to cantilever 23, so that when cantilever 23 rotates, mounting part 241 can maintain its orientation, that is, when cantilever 23 rotates, steering system 3 will not flip along with it.

[0052] The support part 243 is used to support the steering system 3.

[0053] The rotation axis of the cantilever 23, the rotation axis of the mounting part 241, and the rotation axis of the mating arm can be parallel.

[0054] When the first part 244 abuts against the support part 243, the first part 244 and the connecting part 242 can form a V-shaped structure. The first part 244 and the connecting part 242 cooperate to position the steering system 3 at the position of the support part 243.

[0055] The bending structure formed by the first part 244 and the second part can have the inner bending side facing the connecting part 242, so that the mounting part 241, the connecting part 242, the supporting part 243 and the mating arm can form a nearly closed frame structure, reducing the risk of the steering system 3 detaching from the fixed part 24.

[0056] The limiting groove 249 allows the first part 244 to remain against the support part 243.

[0057] In a typical embodiment where the mating arm is rotatably connected to the mounting portion 241, the limiting groove 249 needs to be designed as an openable structure so that the mating arm can be screwed into the limiting groove 249. That is, when the limiting groove 249 is opened, the first portion 244 can be screwed into the limiting groove 249, and then the limiting groove 249 can be closed, allowing the first portion 244 to remain within the limiting groove 249, thus limiting the first portion 244. The disadvantage of this structure is that when the limiting groove 249 itself is designed to be openable, the limiting reliability of the limiting groove 249 is greatly reduced.

[0058] In this application's technical solution, the limiting groove 249 does not need to be an openable structure. When the first part 244 switches to the first state, the first part 244 can deform. On the one hand, the end of the first part 244 can move out of the support part 243. On the other hand, the deformability of the first part 244 provides a larger rotation space for the second part, making it easier to place the steering system 3 into the frame structure formed by the mounting part 241, the connecting part 242, the support part 243, and the mating arm. When the first part 244 switches to the second state, that is, after the steering system 3 is moved into the frame structure, the end of the first part 244 is then inserted into the limiting groove 249. After that, the first part 244 is switched to the second state. At this time, the first part 244 cannot deform and cannot be dislodged from the limiting groove 249.

[0059] See Figure 3 , Figure 6 and Figure 7 In some embodiments, the first part 244 includes a plurality of unit bodies 2415 and an elastic insertion part 245. The plurality of unit bodies 2415 are connected in sequence, and the end unit bodies 2415 are connected to the second part. Between two adjacent unit bodies 2415, one is provided with a shaft body 2417, and the other is provided with a shaft hole and a limiting part 2418. The shaft body 2417 passes through the shaft hole, and the limiting part 2418 is movably connected to the unit body 2415 along the radial direction of the shaft body 2417. The shaft body 2417 includes a limiting segment with a polygonal cross-section, and the limiting part 2418 is provided with a limiting cavity, in which the limiting segment is engaged. Unit 2415 is provided with slot 2416, the extension direction of slot 2416 is perpendicular to the axial direction of shaft 2417, and elastic insertion part 245 is sequentially inserted into slot 2416 of multiple units 2415, and elastic insertion part 245 abuts against the side of limiting part 2418 away from shaft 2417.

[0060] The shaft 2417 and the shaft hole fit together, allowing two adjacent unit bodies 2415 to rotate relative to each other.

[0061] The cross-sectional shape of the limiting segment can be a quadrilateral structure. Correspondingly, the cross-sectional shape of the limiting cavity of the limiting part 2418 is a matching quadrilateral.

[0062] When the limiting segment is inserted into the limiting cavity, the two adjacent unit bodies 2415 cannot rotate. At this time, the first part 244 is in the second state. When the limiting segment moves out of the limiting cavity, the two adjacent unit bodies 2415 can rotate relative to each other. At this time, the first part 244 is in the first state.

[0063] The elastic insertion part 245 is made of a metal material capable of elastic deformation. For example, the elastic insertion part 245 may be spring steel.

[0064] When the flexible insertion part 245 is inserted into the slot 2416, it increases the connection strength of the multiple units 2415 and the support strength for the steering system 3. On the other hand, the flexible insertion part 245 can limit the limiting part 2418. That is, under the action of the flexible insertion part 245, the limiting section of the shaft 2417 is kept in the limiting cavity of the limiting part 2418, so that the multiple units 2415 cannot rotate relative to each other.

[0065] In some embodiments, the support portion 243 is provided with a clearance notch, which is used to avoid the resilient insertion portion 245.

[0066] The clearance notch provides space for the movable resilient insert 245, facilitating the insertion or removal of the resilient insert 245 from the slot 2416.

[0067] When the elastic insertion part 245 is moved, the position of the steering system 3 on the support part 243 can be adjusted to reduce the force exerted by the steering system 3 on the first part 244, so that the elastic insertion part 245 can be pulled out smoothly, and the limiting section can be withdrawn from the limiting cavity at the same time.

[0068] In some embodiments, an elastic element is provided between the limiting portion 2418 and the unit body 2415.

[0069] The elastic element can be a spring, which provides a force to move the limiting part 2418, thereby allowing the limiting segment to move out of the limiting cavity.

[0070] See Figure 4 , Figure 5 and Figure 7 In some embodiments, a limiting shaft 2410 is provided at one end of the elastic insertion part 245 away from the bend of the mating arm, and a locking through groove 2414 is provided at the bend of the mating arm. The locking through groove 2414 is arc-shaped, and an opening is provided on the side of the locking through groove 2414 near the second part.

[0071] The unit 2415 furthest from the second part can be provided with a limiting structure, which prevents the elastic insertion part 245 from being completely pulled out of the unit 2415, thus preventing the elastic insertion part 245 from detaching from the first part 244. The limiting structure can be selected from existing structures, and will not be described in detail here.

[0072] The second part of the arm serves to limit the steering system 3 on the one hand, and guides the steering system 3 when it is removed on the other hand, allowing the steering system 3 to descend slowly.

[0073] The resilient insertion portion 245 can be configured such that when the resilient insertion portion 245 is not subjected to force, the resilient insertion portion 245 is in a bent state, such as... Figure 4 and Figure 5 As shown, the elastic insertion portion 245 can be in an upwardly curved state. With this configuration, on the one hand, when the elastic insertion portion 245 is inserted into the slot 2416, in the area between the two unit bodies 2415, the elastic insertion portion 245 is still in a slightly curved state, and the outwardly convex side faces the limiting portion 2418. This allows the elastic insertion portion 245 to apply a force toward the shaft 2417 to the limiting portion 2418, so that the limiting segment can be located in the limiting cavity. On the other hand, when the elastic insertion part 245 is pulled out, the elastic insertion part 245 bends upward, and at the same time, the bent part of the cooperating arm can rotate further towards the support part 243 by a certain distance, so that the limiting shaft 2410 can be inserted into the opening of the locking through groove 2414. At this time, the position of the steering system 3 can be manually adjusted to pull the limiting shaft 2410 of the elastic insertion part 245 to move, so that the limiting shaft 2410 is inserted into the opening of the locking through groove 2414. At this time, the steering system 3 can be fitted onto the first part 244.

[0074] The advantage of incorporating steering system 3 into the first part 244 is that, firstly, as Figure 3As shown, when the mating arm rotates counterclockwise, the first part 244 tends to wrap around the bend of the mating arm, which allows the steering system 3 to be gradually and slowly lifted. During the lifting process, the steering system 3 applies force to the elastic insertion part 245, so that the limiting shaft 2410 will not come out from the opening end of the locking through slot 2414, which improves the stability and reliability of the lifting steering system 3. Furthermore, the steering system 3 can slowly rise along the side of the bend of the mating arm near the connecting part 242, which reduces the risk of the steering system 3 jumping when it moves to the top of the bend and ensures that the steering system 3 can move smoothly to the second part. When the steering system 3 moves to the top of the bend of the mating arm, the mating arm rotates further. At this time, the steering system 3 can move to the second part. The steering system 3 can push the elastic insertion part 245 to move, and then the elastic insertion part 245 drives the limiting shaft 2410 to move towards the opening of the locking through groove 2414, so that the limiting shaft 2410 can be moved out of the locking through groove 2414. The sleeve structure formed by the elastic insertion part 245 and the first part 244 opens, and the steering system 3 moves to the second part. Since the second part is in an inclined state, the steering system 3 can be guided by the second part, so that the steering system 3 can slowly slide to the set position.

[0075] In this embodiment of the application, configuring the first part 244 as deformable has another advantage: it increases the rotation angle range of the second part.

[0076] See Figure 3 , Figure 4 , Figure 6 and Figure 7 In some embodiments, the second part includes a first support arm 246, a second support arm 248, and an elastic movable sleeve 247. The first support arm 246 is connected to the first part 244, and the second support arm 248 is rotatably connected to the first support arm 246. The first support arm 246 and the second support arm 248 form a bent structure. A first support roller 2411 is provided at the connection between the first support arm 246 and the first part 244, a second support roller 2412 is provided at the connection between the first support arm 246 and the second support arm 248, and a third support roller 2413 is provided at the end of the second support arm 248 away from the first support arm 246. The elastic movable sleeve 247 is sleeved on the first support roller 2411, the second support roller 2412, and the third support roller 2413.

[0077] The elastic movable sleeve 247 can be made of a flexible material, such as rubber.

[0078] Under the action of the first support roller 2411, the second support roller 2412 and the third support roller 2413, the elastic movable sleeve 247 can form a triangular structure.

[0079] When the first part 244 switches from the second state to the first state, the second part can rotate a certain angle toward the support part 243. At this time, the part of the elastic moving sleeve 247 located between the first support roller 2411 and the third support roller 2413 can play a limiting role on the steering system 3, thereby improving the fixing stability of the fixed part 24 on the steering system 3.

[0080] When removing steering system 3, as Figure 3 As shown, with the arm rotating counterclockwise, the steering system 3 gradually moves from the first part 244 to the second part. When the steering system 3 and the elastic moving sleeve 247 come into contact, under the action of friction, the elastic moving sleeve 247 and the steering system 3 can move together, reducing the risk of sliding friction between the steering system 3 and the second part. Furthermore, as the elastic moving sleeve 247 moves along the first support arm 246, under the action of the elastic moving sleeve 247, the end of the second support arm 248 away from the first support arm 246 can gradually close towards the first support arm 246. This makes the steering system 3 experience greater resistance as it gets closer to the end of the first support arm 246, allowing the steering system 3 to be gradually decelerated.

[0081] When the steering system 3 is about to move to the first support arm 246, there are two possible implementation methods as needed. One method is to keep the first support arm 246 and the second support arm 248 in a bent state. When the steering system 3 moves to the end of the first support arm 246, it can be fixed by the first support arm 246 and the second support arm 248. Simultaneously, the steering system 3 is partially supported by the placement surface of the main body. That is, when the steering system 3 moves to the test position, it is fixed by the fixing component 24 and the placement surface. The advantage of this fixing method is that it reduces the risk of external components such as the hydraulic pump and its accessories obstructing the fixing of the steering system 3. The other method is to rotate the second support arm 248. In this case, the second support arm 248 can extend the distance by which the second part of the transportable steering system 3 can move, allowing the steering component to finally move to the set position of the main body, such as the positioning block 12.
