Abstract
Description
Technical Field
[0001] The present application belongs to the technical field of limiting devices, and in particular relates to a footrest limiting assembly and a vehicle. Background Art
[0002] In the specialized vehicle industry, vehicles are equipped with outriggers for ground support and a vehicle transport hatch. To perform specialized operations, the hatch is opened, the outriggers are flipped out, and the outriggers' footplates are lowered to the ground to support the vehicle.
[0003] During vehicle transportation, the outrigger mechanism first retracts the footplate, then flips it back into the transport cabin, and finally closes the hatch. The outrigger mechanism's extensions are typically connected to the footplate using a ball joint to accommodate varying ground conditions. When the outrigger mechanism is retracted into the transport cabin, the footplate will swing slightly under the force of gravity, and will also swing randomly during transportation. Generally, to facilitate the flipping and lowering of the outrigger mechanism to support the ground, the outrigger mechanism is located at the rear of the transport cabin, with the footplate close to the inner wall of the hatch. To prevent collision and interference between the footplate and the hatch during transportation and hatch closing, it is necessary to ensure that the footplate automatically returns to level and is securely locked after the extensions are retracted.
[0004] In the related art, after the outrigger mechanism's footplate is retracted, the footplate will swing randomly, causing the footplate to collide and interfere with the hatch cover when the outrigger mechanism is retracted. The outrigger mechanism has low retraction efficiency, and during vehicle transportation, the footplate will swing randomly, generating abnormal noise. Utility Model Content

[0015] The reset member is located in the abutment member, the first limiting member is located in the guide member, and the side close to the abutment member is located in the abutment member, and is slidably connected to the abutment member along the sliding direction of the abutment member.
[0016] In some embodiments, the first limiting member is threadedly connected to the guide member so that the first limiting member is movably connected to the guide member along the sliding direction of the abutting member.
[0017] In some embodiments, the guide assembly further includes a second limiting member, which is mounted on the guide member and abuts against the first limiting member.
[0018] In some embodiments, the second limiting member is movably connected to the guiding member along the sliding direction of the abutting member, and is located on a side of the first limiting member away from the restoring member.
[0019] In some embodiments, the guide member has a mounting cavity and a first opening and a second opening communicating with the mounting cavity; the first limiting member and the abutting member are located in the mounting cavity, and a side of the abutting member away from the first limiting member extends out of the safety cavity through the second opening;
[0020] The first limiting member is provided with an oil filling port and an oil outlet which are connected. The oil outlet is connected to the mounting cavity. The oil filling port is arranged opposite to the first port.
[0021] In some embodiments, the guide assembly further includes a shielding cover, which is detachably connected to the guide member. When the shielding cover is connected to the guide member, the shielding cover shields the first opening.
[0022] In a second aspect, an embodiment of the present application provides a vehicle, comprising:
[0023] body;
[0024] A leg mechanism comprising a fixing member, an extension member, and a footplate, wherein at least a portion of the extension member is located within the fixing member and is slidably connected to the fixing member along the length of the extension member, the footplate is hinged to a side of the extension member away from the fixing member, and the fixing member is fixedly connected to the vehicle body;
[0025] The foot plate limiting assembly described in the first aspect above, multiple foot plate limiting assemblies are arranged at circumferential intervals around the protruding member, and the guide assembly is fixedly connected to the fixing member.
[0026] The utility model has at least the following beneficial effects:
[0027] The footrest limiter assembly is mounted on the fixed member of the leg mechanism and is used to limit the position of the footrest, which is hinged to the extension member of the leg mechanism. The footrest limiter assembly includes a guide assembly, an abutment member, and a reset member. The guide assembly is fixedly connected to the fixed member, the abutment member is slidably connected to the guide assembly, and two sides of the reset member act on the guide assembly and the abutment member respectively.

[0028] With this design, when the footplate is extended to support the ground, the abutment is extended to its longest length under the action of the reset member. The abutment does not contact the footplate and does not interfere with the footplate, thereby ensuring the automatic swing amplitude of the footplate and allowing the footplate to freely contact the ground. When the footplate is retracted, the abutment can abut against the footplate, thereby limiting the footplate and reducing the amount of swing after the footplate is retracted. When the support leg mechanism is provided with multiple footplate limit assemblies, each abutment abuts against various parts of the footplate, limiting various areas of the footplate, and thus fixing the footplate so that the footplate will not swing randomly after it is retracted, thereby avoiding the problem of the footplate randomly swinging and interfering with the hatch and other components, thereby generating abnormal noise. The setting of the guide assembly and the reset member allows the abutment to slide along the guide member under the action of the footplate and to be reset by the reset member when the footplate is extended. This design allows the abutment to have a certain range of motion, which can ensure that when multiple footplate limit assemblies are set, the abutment of each footplate limit assembly can contact the footplate, and can also reduce the requirements for the installation accuracy of the footplate limit assembly, thereby reducing the difficulty of installation.

[0037] In the related art, in order to enable the foot pan of the outrigger mechanism to adapt to different ground conditions, the foot pan of the outrigger mechanism is hinged on the protruding piece of the outrigger mechanism, resulting in the foot pan being able to swing freely after being retracted under the drive of the protruding piece, causing problems such as collision and interference between the foot pan and the cabin cover and abnormal noise when the outrigger mechanism is retracted.
[0038] Therefore, in the related art, there is a technical problem that the footrest can swing freely after the footrest is retracted. The embodiment of the present application provides a footrest limit assembly and a vehicle, which can at least to some extent solve the technical problem of the footrest swinging freely after the footrest is retracted.
[0039] The present application is described below with reference to specific embodiments and with reference to the accompanying drawings:
[0040] like Figure 1 and Figure 2 As shown, the foot plate limiting assembly 100 is installed on the fixing member 210 of the leg support mechanism 200 and is used to limit the foot plate 230 hinged on the extension member 220 of the leg support mechanism 200 .
[0041] The fixing member 210 can drive the extending member 220 to move along the length direction of the extending member 220 to adjust the extension amount of the extending member 220. The leg mechanism 200 can be a hydraulic leg mechanism 200, a pneumatic leg mechanism 200, a screw-nut leg mechanism 200, etc., which is not limited in this application, and the specific structures and installation methods of these leg mechanisms 200 are known to those skilled in the art. In some embodiments, the leg mechanism 200 is a hydraulic leg mechanism 200, the fixing member 210 is the cylinder body of the hydraulic leg mechanism 200, and the extending member 220 is the piston rod of the hydraulic leg mechanism 200. One end of the piston rod is located in the cylinder body and is slidably connected to the cylinder body along the length direction of the piston rod. The cylinder body may include components such as a cylinder barrel, a sealing ring, and a guide sleeve. The foot plate 230 is installed at the other end of the piston rod. The structures of the cylinder body and the piston rod are diverse and are known to those skilled in the art, so they will not be described in detail here. For the convenience of introducing this application, this application will be introduced below as an example of the leg mechanism 200 being a hydraulic leg mechanism 200.
[0042] The foot plate limiting assembly 100 includes a guide component 110 , an abutment member 120 and a reset member 130 .
[0043] The guide assembly 110 is used to be fixedly connected to the fixing member 210, the abutment 120 is slidably connected to the guide assembly 110, and the two sides of the reset member 130 act on the guide assembly 110 and the abutment 120 respectively. The abutment 120 is used to abut the foot plate 230 when the foot plate 230 is in the retracted condition to limit the foot plate 230. The reset member 130 is used to store energy and reset the abutment 120 when the foot plate 230 is in the extended condition.
[0044] When the foot plate limiting assembly 100 is in use, the guide assembly 110 is fixedly connected to the fixing member 210 of the leg mechanism 200, and the abutment member 120 and the reset member 130 are mounted on the guide assembly 110. Therefore, the foot plate limiting assembly 100 does not follow the movement of the extension member 220 of the leg mechanism 200. The abutment member 120 is slidably connected to the guide assembly 110, which provides guidance for the abutment member 120. The two sides of the reset member 130 are in contact with the guide assembly 110 and the abutment member 120 respectively. The reset member 130 provides a reset force for the abutment member 120, so that the reset member 130 can return to its original state after separation from the foot plate 230.
[0045] With this design, when the footplate 230 is extended to support the ground, the abutment 120 is extended to its longest length under the action of the reset member 130. The abutment 120 does not contact the footplate 230 and does not interfere with the footplate 230, thereby ensuring the automatic swing amplitude of the footplate 230 and allowing the footplate 230 to freely contact the ground. When the footplate 230 is retracted, the abutment 120 can abut against the footplate 230, thereby limiting the footplate 230 and reducing the amount of swing after the footplate 230 is retracted. When the leg mechanism 200 is provided with multiple footplate limit assemblies 100, each abutment 120 abuts against various parts of the footplate 230, limiting various areas of the footplate 230, and thus fixing the footplate 230 so that the footplate 230 will not swing randomly after retraction, thereby avoiding the problem of the footplate 230 randomly swinging and interfering with the cabin cover and other components, thereby generating abnormal noise. The setting of the guide assembly 110 and the reset member 130 allows the abutment 120 to slide along the guide member 112 under the action of the foot plate 230 and to be reset by the reset member 130 when the foot plate 230 is extended, which helps to ensure that the abutment 120 always presses against the foot plate 230 to ensure the effect of limiting the foot plate 230. This design allows the abutment 120 to have a certain range of motion, which can ensure that when multiple foot plate limit assemblies 100 are set, the abutment 120 of each foot plate limit assembly 100 can contact the foot plate 230, and can also reduce the requirements for the installation accuracy of the foot plate limit assembly 100, thereby reducing the difficulty of installation.
[0046] In some embodiments, the guide assembly 110 includes a connecting seat 111, a guide member 112 and a first limiting member 113. The connecting seat 111 is used to be fixedly connected to the fixing member 210. The guide member 112 is fixedly connected to the connecting seat 111. The abutment 120 is slidingly connected to the guide member 112. The first limiting member 113 is installed on the guide member 112. The two sides of the reset member 130 act on the first limiting member 113 and the abutment 120 respectively.
[0047] The connecting seat 111 is the installation base of the guide member 112, which supports and fixes the guide member 112. The connecting seat 111 is fixed on the fixing member 210. The guide member 112 can be fixed on the connecting seat 111 by welding, bonding, bolt connection, etc. The guide member 112 is guided by the abutment 120, and the abutment 120 is slidably connected to the guide member 112. The guide assembly 110 limits the reset member 130 through the first limit member 113 to ensure that the reset member 130 can reset the abutment 120. One side of the reset member 130 contacts the first limit member 113, and the other side contacts the abutment 120. The guide assembly 110 is composed of a plurality of components connected together. Each component is processed separately and then assembled together, which helps to reduce the processing difficulty of the guide assembly 110 and facilitates the processing and manufacturing of the foot plate limit assembly 100.
[0048] In some embodiments, the reset member 130 is an elastic member. The reset member 130 is located between the first limiting member 113 and the abutting member 120 . The first limiting member 113 is movably connected to the guide member 112 along the sliding direction of the abutting member 120 .
[0049] The reset member 130 is located between the first stopper 113 and the abutment 120 and is in a compressed state. The reset member 130 may be a spring, for example. Because the first stopper 113 is movably connected to the guide member 112 along the sliding direction of the abutment 120, the first stopper 113 can move relative to the abutment 120, thereby allowing the spacing between the first stopper 113 and the abutment 120 to be adjusted. This allows the maximum length of the reset member 130 between the first stopper 113 and the abutment 120 to be adjusted, thereby adjusting the initial compression of the reset member 130. With this design, the initial compression of the spring can be adjusted based on the weight of the footplate 230 and the impact load during vehicle transportation, ensuring that the footplate 230 remains securely locked by the abutment 120 under extreme operating conditions, preventing the footplate 230 from swinging and colliding with or interfering with the vehicle's hatch.
[0050] In some embodiments, the first limiting member 113 is threadedly connected to the guide member 112 so that the first limiting member 113 is movably connected to the guide member 112 along the sliding direction of the abutting member 120 .
[0051] It is easy to understand that the first limiting member 113 is provided with an external thread on the outside and the guide member 112 is provided with an internal thread on the inside, or the first limiting member 113 is provided with an internal thread on the outside and the guide member 112 is provided with an external thread on the inside, so that the first limiting member 113 can be threadedly matched with the guide member 112. The axes of the internal thread and the external thread are parallel to the sliding direction of the abutment 120, so that the first limiting member 113 can move along the sliding direction of the abutment 120 when it is rotated. When the position of the first limiting member 113 needs to be adjusted, the first limiting member 113 can be rotated. In order to facilitate the rotation of the first limiting member 113, polygonal protrusions, polygonal grooves, cross grooves, straight grooves and other structures can be processed on the first limiting member 113, so that the user can use tools such as a sleeve and a screwdriver to apply force to the first limiting member 113 and twist the first limiting member 113. The first limit member 113 and the guide member 112 are connected in a threaded manner to achieve a movable connection, so that the first limit member 113 can be infinitely adjusted in the sliding direction of the abutment 120, so that the distance between the first limit member 113 and the abutment 120 can be infinitely adjusted, and further the initial compression amount of the reset member 130 can be infinitely adjusted, which helps to ensure that the foot plate limit assembly 100 is suitable for a variety of different working conditions.
[0052] In some embodiments, the first limiting member 113 is located inside the guide member 112 , an outer peripheral wall of the first limiting member 113 is provided with an external thread, and an inner wall of the guide member 112 is provided with an internal thread.
[0053] In some embodiments, the side of the abutment 120 close to the first limiting member 113 is located in the guide member 112 and is slidably connected to the guide member 112; the reset member 130 is located in the abutment 120, the first limiting member 113 is located in the guide member 112 and the side close to the abutment 120 is located in the abutment 120, and is slidably connected to the abutment 120 along the sliding direction of the abutment 120.
[0054] Specifically, a mounting groove is defined on the side of the abutment member 120 that is close to the first limiting member 113. The reset member 130 is located within the mounting groove, and the side of the reset member 130 that is away from the first limiting member 113 contacts the bottom of the mounting groove. The side of the first limiting member 113 that is close to the abutment member 120 extends into the mounting groove and slidably engages with the inner wall of the mounting groove to be slidably connected to the abutment member 120. The side of the reset member 130 that is close to the abutment member 120 contacts the abutment member 120. With this design, the abutment member 120 is not only slidably connected to the guide member 112, but also to the first limiting member 113, thereby improving the sliding stability of the abutment member 120. The reset member 130 is located inside the abutment 120, and the first limiting member 113 extends into the abutment 120, so that the abutment 120 can provide guidance for the reset member 130, ensuring that the reset member 130 is deformed along the extension and contraction direction of the abutment 120, and providing protection for the reset member 130, and also improving the integration of the foot plate limiting assembly 100, which helps to reduce the size of the foot plate limiting assembly 100.
[0055] In some embodiments, the guide assembly 110 further includes a second limiting member 115 . The second limiting member 115 is installed on the guide member 112 and abuts against the first limiting member 113 .
[0056] The second limiting member 115 is fixedly mounted on the guide member 112. The second limiting member 115 abuts against the first limiting member 113 to limit the first limiting member 113, thereby preventing the first limiting member 113 from shifting due to vehicle vibration or other reasons during vehicle driving, and ensuring that the first limiting member 113 is in an accurate position to ensure the accuracy of the initial compression amount of the reset member 130.
[0057] In some embodiments, the second limiting member 115 is movably connected to the guide member 112 along the sliding direction of the abutting member 120 , and is located on a side of the first limiting member 113 away from the restoring member 130 .
[0058] The side of the first limiting member 113 closest to the reset member 130 is abutted by the reset member 130, and the reset member 130 applies a force to the first limiting member 113, making it easier for the first limiting member 113 to move away from the reset member 130. In these embodiments, the second limiting member 115 is disposed on the side of the first limiting member 113 away from the reset member 130 to limit the side of the first limiting member 113 away from the reset member 130 and prevent the first limiting member 113 from moving away from the reset member 130. In addition, because the second limiting member 115 is movably connected to the guide member 112 along the sliding direction of the abutting member 120, the second limiting member 115 can move relative to the guide member 112. When the first limiting member 113 is in different positions, the second limiting member 115 can be moved so that the second limiting member 115 abuts against the first limiting member 113.
[0059] In some embodiments, the second limiting member 115 is located within the guide member 112. The outer peripheral wall of the second limiting member 115 is provided with an external thread, and the inner wall of the guide member 112 is provided with an internal thread, so that the first limiting member 113 can be threadedly engaged with the guide member 112. The axes of the internal and external threads are parallel to the sliding direction of the abutment member 120, so that the second limiting member 115 can be movably connected to the guide member 112 along the sliding direction of the abutment member 120. With this design, the second limiting member 115 can be moved along the sliding direction of the abutment member 120 by rotating the second limiting member 115.
[0060] In some embodiments, the guide member 112 has an installation cavity 112a and a first port 112b and a second port 112c connected to the installation cavity 112a. The first limiting member 113 and the abutment member 120 are located in the installation cavity 112a, and the side of the abutment member 120 away from the first limiting member 113 extends out of the installation cavity 112a through the second port 112c; the first limiting member 113 is provided with a connected oil filling port 113a and an oil outlet port 113b, the oil outlet port 113b is connected to the installation cavity 112a, and the oil filling port 113a is arranged opposite to the first port 112b.
[0061] The first stopper 113, the second stopper 115, and the abutting member 120 extend into the mounting cavity 112a through the first opening 112b. The side of the abutting member 120, away from the first stopper 113, extends out of the mounting cavity 112a through the second opening 112c and abuts against the foot plate 230. The outer wall of the abutting member 120 slidably engages with the inner wall of the mounting cavity 112a to achieve a sliding connection between the abutting member 120 and the guide member 112. During the movement of the abutment 120, it will contact the guide member 112 and the first limit member 113, and there will be friction. By providing an oil filling port 113a and an oil outlet 113b on the first limit member 113, lubricating oil can be injected through the oil filling port 113a and discharged into the installation cavity 112a through the oil outlet 113b, entering the gap between the guide member 112 and the first limit member 113, entering the gap between the first limit member 113 and the abutment 120, and entering the gap between the first limit member 113 and the guide member 112, thereby lubricating the guide member 112 and the first limit member 113, lubricating the guide member 112 and the abutment 120, and lubricating the first limit member 113 and the abutment 120, reducing the friction force encountered by the abutment 120 during movement, ensuring the smoothness of the movement of the abutment 120, reducing the friction force encountered by the first limit member 113 during rotation, and ensuring the smoothness of the rotation of the first limit member 113. The oil filling port 113 a is arranged opposite to the first port 112 b , so that the oil filling port 113 a can be exposed to the outside through the first port 112 b , so that users can fill lubricating oil through the oil filling port 113 a .
[0062] In some embodiments, the guide assembly 110 further includes a shielding cover 114 . The shielding cover 114 is detachably connected to the guide member 112 . When the shielding cover 114 is connected to the guide member 112 , the shielding cover 114 shields the first opening 112 b .
[0063] The shielding cover 114 and the guide member 112 can be detachably connected by bolts, threads, or other means. When the shielding cover 114 is connected to the guide member 112, the shielding cover 114 can shield the first opening 112b, preventing rainwater, dust, and the like from entering the installation cavity 112a through the first opening 112b and causing corrosion or damage to the first limiter 113, the abutting member 120, the second limiter 115, and the reset member 130 within the installation cavity 112a, thereby ensuring the stable operation of the first limiter 113, the abutting member 120, and the second limiter 115. When the shielding cover 114 is separated from the guide member 112, the oil filling port 113a is exposed through the first opening 112b, allowing the user to add lubricating oil through the oil filling port 113a. In addition, when the shielding cover 114 is separated from the guide member 112 , the first limiting member 113 , the second limiting member 115 , the abutting member 120 , the restoring member 130 and the like can be disassembled through the first opening 112 b .
[0064] In some embodiments, the shielding cover 114 is threadedly connected to the guide member 112 .
[0065] In some embodiments, the second limiting member 115 has an avoidance through hole 115 a for avoiding the oil filling hole 113 a , so that the user can fill the oil filling hole 113 a with oil without removing the second limiting member 115 .
[0066] The following describes the working principle of the foot plate limit assembly 100:
[0067] Multiple footplate limit assemblies 100 are fixedly connected to the fixing part 210 of the leg support mechanism 200, and multiple footplate limit assemblies 100 are arranged at intervals around the circumference of the protruding part 220. Specifically, the connecting seat 111 of the footplate limit assembly 100 is fixedly connected to the fixing part 210, and the abutment 120 is arranged toward the leg plate, and the sliding direction of the abutment 120 is parallel to the sliding direction of the protruding part 220. When it is necessary to adjust the initial compression amount of the reset member 130, rotate the shielding cover 114 to remove the shielding cover 114 from the guide member 112, then rotate the second limit member 115 to remove the second limit member 115 from the guide member 112, then rotate the first guide member 112 to adjust the distance between the first guide member 112 and the abutment member 120, and then adjust the initial compression amount of the reset member 130. After adjusting the first guide member 112, screw the second limit member 115 into the guide member 112 until the second limit member 115 abuts against the first guide member 112, and then screw the shielding cover 114 onto the guide member 112. When oil needs to be added to the oil filling port 113a, the shielding cover 114 is rotated to remove it from the guide member 112. The oil gun is then aimed at the oil filling port 113a on the first stopper 113 to add oil. After oiling is completed, the shielding cover 114 is screwed onto the guide member 112. When the foot plate 230 retracts, after the foot plate 230 retracts a certain distance, the foot plate 230 contacts the abutment 120, driving the abutment 120 to slide toward the first stopper 113. The reset member 130 is compressed until the foot plate 230 is fully retracted. Under the action of the multiple abutment members 120, the foot plate 230 is firmly fixed and cannot swing. After the foot plate 230 is extended, the reset member 130 applies a force to the abutment 120, driving the abutment 120 to slide away from the first stopper 113 until the first stopper 113 abuts the guide member 112.
[0068] Based on the same inventive concept, an embodiment of the present application further provides a vehicle, comprising a vehicle body, a leg support mechanism 200, and the aforementioned footrest limiting assembly 100. The leg support mechanism 200 comprises a fixing member 210, an extension member 220, and a footrest 230. At least a portion of the extension member 220 is located within the fixing member 210 and is slidably connected to the fixing member 210 along the length direction of the extension member 220. The footrest 230 is hinged to a side of the extension member 220 away from the fixing member 210, and the fixing member 210 is fixedly connected to the vehicle body. A plurality of footrest limiting assemblies 100 are arranged at intervals around the circumference of the extension member 220, and the guide assembly 110 is fixedly connected to the fixing member 210.
[0069] The vehicle can be an ordinary car for carrying passengers, a special vehicle for transporting aircraft, etc., or a vehicle with a sling (also known as a car crane), etc. The type of vehicle is not limited in this application. The structure of the body of different types of vehicles is different and is not limited in this application. The body may include components such as a drive assembly. The fixing part 210 of the leg mechanism 200 is fixedly connected to the vehicle body. When the leg mechanism 200 needs to support the ground, the extension part 220 can be extended by the action of the fixing part 210, so that the foot plate 230 is in contact with the ground. When the leg mechanism 200 is not supporting, the extension part 220 of the leg mechanism 200 is retracted, and the foot plate 230 is not in contact with the ground.
[0070] Multiple footplate limiter assemblies 100 are spaced apart circumferentially around the extension 220 to limit various areas of the footplate 230. This ensures that the footplate 230 remains fixed after retraction and prevents random swinging. This prevents the footplate 230 from colliding with components such as the vehicle's hatch, causing unusual noise, and other issues. In some embodiments, three footplates 230 are provided on a single leg mechanism 200.
