Description

Technical Field

[0001] This utility model relates to the field of warehouse vehicles, specifically to a warehouse station platform with shock absorption and a warehouse vehicle. Background Technology

[0002] Warehouse trucks are heavy-duty tools used for transporting heavy items. Electric warehouse trucks are commonly used. The platform is a component for operators to stand on and operate the vehicle, and it is an indispensable part of the warehouse truck. When the operator stands on the platform to operate the vehicle, the operator will also be vibrated when the vehicle travels over bumpy roads, which will affect the operation and may even cause the operator to fall off the platform. Utility Model Content

[0003] To address the aforementioned problems, this utility model provides a warehouse station platform and a warehouse vehicle with shock absorption.

[0004] To achieve the above objectives, the technical solution provided by this utility model is as follows: A shock-absorbing storage station platform includes a platform hinged to a vehicle frame; it further includes a shock-absorbing mechanism comprising a fixed abutment portion mounted on the vehicle frame and a shock-absorbing portion mounted on the platform. The shock-absorbing portion includes a limiting rod, a first bushing, a second bushing, and a compression spring. The limiting rod is movably mounted on the platform along its axial direction. The first bushing and the second bushing are spaced apart and both are sleeved on the limiting rod. The compression spring is disposed between the first bushing and the second bushing, such that the first bushing abuts against the first end of the limiting rod and the second bushing abuts against the platform. The first end of the limiting rod abuts against the fixed abutment portion.

[0005] Furthermore, the station plate includes an upper cover plate, a bottom plate, and a connecting stiffener plate, which are connected sequentially from bottom to top; the shock-absorbing part is disposed between the bottom plate and the upper cover plate and installed on the connecting stiffener plate.

[0006] Furthermore, the second end of the limiting rod passes through the station plate and is fixed with a limiting component to prevent the limiting rod from detaching from the station plate.

[0007] Furthermore, the connection position between the limiting rod and the limiting component is adjustable.

[0008] Furthermore, the limiting rod is a first screw, the limiting component is a limiting nut, the limiting nut is screwed onto the rod portion of the first screw, and the nut of the first screw is the first end of the limiting rod; the nut of the limiting rod is inserted into the station plate, and the station plate forms a circumferential limit on the nut.

[0009] Furthermore, both the first bushing and the second bushing have abutting bosses extending radially outward on their outer peripheries. The compression spring is sleeved on the outer periphery of the first bushing and the second bushing, with the first end of the compression spring abutting against the abutting boss of the first bushing and the second end of the compression spring abutting against the abutting boss of the second bushing.

[0010] Furthermore, the first bushing is provided with an elastic buffer block at the end facing the second bushing, and the second bushing corresponds to the elastic buffer block on the first bushing; or, the second bushing is provided with an elastic buffer block at the end facing the first bushing, and the first bushing corresponds to the elastic buffer block on the second bushing.

[0011] Furthermore, the fixed abutment part includes a second screw and two fixing nuts. The frame has a mounting hole, the second screw passes through the mounting hole of the frame, and the two fixing nuts are respectively screwed onto the second screw and clamp and fix the frame; the nuts of the second screw face the shock-absorbing part.

[0012] Furthermore, the number of the damping mechanisms is two sets, and the two sets of damping mechanisms are distributed in an axisymmetric manner.

[0013] A storage vehicle comprising at least the aforementioned shock-absorbing storage platform.

[0014] The technical solution provided by this utility model has the following beneficial effects: Using the solution of this application, when the operator stands on the platform, the operator's weight causes the compression spring to be compressed by a certain stroke, reducing the distance between the first and second bushings. During driving, when the vehicle bumps, the downward pressure on the platform increases instantaneously, causing the platform to swing down a certain distance. The compression spring is then compressed and contracts again before returning to its original shape. The vibration is absorbed by the compression spring, resulting in a good shock absorption effect. Simultaneously, the distance between the first and second bushings limits the lowest possible position of the platform, ensuring the operator can stand stably on it.

[0015] The design of the shock absorption mechanism, including the limit rod, first bushing, second bushing, and compression spring, is a non-fixed assembly method, which makes disassembly and assembly easier. Attached Figure Description

These drawings are part of the disclosure of the present invention and are mainly used to illustrate the embodiments, and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these drawings, those skilled in the art should be able to understand other possible implementations and the advantages of the present invention.

They are used only for the convenience of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0019] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0020] Reference Figures 1 to 4 As shown, this embodiment provides a storage station platform with shock absorption, including a station platform 2, which is hinged to the frame 1. In this embodiment, the two sides of the station platform 2 are hinged to the frame 1 through hinge members 30, so that the station platform 2 can swing up and down and can be folded upward for storage.

[0021] It also includes a shock-absorbing mechanism, which includes a fixed abutment part 10 mounted on the frame 1 and a shock-absorbing part 20 mounted on the platform 2. In this embodiment, the platform 2 includes an upper cover plate 3, a connecting stiffener 4 and a bottom plate 5, which are connected sequentially from bottom to top. The shock-absorbing part 20 is disposed between the bottom plate 5 and the upper cover plate 3 and is mounted on the connecting stiffener 4. The shock-absorbing part 20 has a hidden design and can also be well protected.

[0022] Specifically, the shock-absorbing part 20 includes a limiting rod 21, a first bushing 22, a second bushing 23, and a compression spring 24. The limiting rod 21 is movably mounted on the station plate 2 along its axial direction. Specifically, the limiting rod 21 is movably mounted on the connecting rib plate 4 of the station plate 2. The first bushing 22 and the second bushing 23 are spaced apart and both are sleeved on the limiting rod 21. The compression spring 24 is disposed between the first bushing 22 and the second bushing 23, so that the first bushing 22 abuts against the first end of the limiting rod 21 and the second bushing 23 abuts against the connecting rib plate 4 of the station plate 2. The first end of the limiting rod 21 abuts against the fixed abutment part 10.

[0023] Using the solution of this application, when the operator stands on the platform 2, the operator's weight will cause the compression spring 24 to be compressed by a certain stroke, and the distance between the first bushing 22 and the second bushing 23 will decrease; that is, the platform 2 will have an initial downward displacement distance. During driving, when the vehicle bumps, the downward pressure on the platform 2 increases instantaneously, causing the platform 2 to continue to swing downward a certain distance. The compression spring 24 is compressed and contracted again, and then returns to its original deformation. The vibration is absorbed by the compression spring 24, achieving a good shock absorption effect. At the same time, the distance between the first bushing 22 and the second bushing 23 is set to limit the lowest position that the platform 2 can swing downward, ensuring that the operator can stand stably on the platform 2. Specifically, the elastic coefficient of the compression spring 24 and the distance between the first bushing 22 and the second bushing 23 determine the effective load-bearing capacity of the platform 2. The effective load-bearing capacity means that the platform 2 still has a shock absorption effect after bearing the weight; therefore, a suitable compression spring 24 and the distance between the first bushing 22 and the second bushing 23 can be selected to achieve the preset effect.

[0024] The shock absorption mechanism is designed so that the limiting rod 21, the first bushing 22, the second bushing 23, and the compression spring 24 are assembled in a non-fixed manner, which makes disassembly and assembly easier. During installation, the first bushing 22, the compression spring 24, and the second bushing 23 are placed sequentially, and then the limiting rod 21 is inserted all at once. During disassembly, the limiting rod 21 can be pulled out directly. As shown in the figure, the first bushing 22, the second bushing 23, and the compression spring 24 are assembled between the two support plates (the first support plate 8 and the second support plate 9) of the connecting stiffener 4. The first support plate 8 has a first through hole 6, and the second support plate 9 has a second through hole 7. The limiting rod 21 enters through the first through hole 6 of the first support plate 8, then sequentially enters through the first bushing 22 and the second bushing 23, and finally exits through the second through hole 7 of the second support plate 9.

[0025] Furthermore, to prevent the limiting rod 21 from falling off, in this embodiment, a limiting design is implemented between the limiting rod 21 and the connecting stiffener 4. Specifically, the second end of the limiting rod 21 passes through the second support plate 9 of the connecting stiffener 4 of the station plate 2 and is fixed with a limiting member 26 to prevent the limiting rod 21 from detaching from the station plate 2. When the station plate 2 is flipped upwards, the limiting rod 21 will not fall downwards.

[0026] Furthermore, the connection position between the limiting rod 21 and the limiting member 26 is adjustable. In this way, the preload of the compression spring 24 and the distance between the first bushing 22 and the second bushing 23 can be adjusted according to actual needs. For example, if it is necessary to increase the initial compression of the compression spring 24, the limiting member 26 is fixed closer to the first end of the limiting rod 21. At this time, the distance between the first bushing 22 and the second bushing 23 also becomes smaller, and the maximum downward movement of the station plate 2 also becomes smaller. Conversely, if it is necessary to decrease the initial compression of the compression spring 24, the limiting member is fixed closer to the second end of the limiting rod 21. At this time, the distance between the first bushing 22 and the second bushing 23 becomes larger, and the maximum downward movement of the station plate 2 also becomes larger.

[0027] Specifically, the limiting rod 21 is a first screw 210, and the limiting member 26 is a limiting nut 260. The limiting nut 260 is screwed onto the rod portion 211 of the first screw 210, and the nut of the first screw 210 (defined as the first nut 212) is the first end of the limiting rod 21. The nut of the limiting member 26 (i.e., the first nut 212) passes through the station plate 2, specifically through the first through hole 6 of the first support plate 8 of the connecting stiffener 4. The end of the rod portion 211 of the first screw 210 is the second end of the limiting rod 21, and the rod portion 211 passes through the second through hole 7 of the second support plate 9 and is screwed and fixed with the limiting nut 260. By using the cooperation of the first screw 210 and the limiting nut 260, the position of the first screw 210 can be adjusted arbitrarily by screwing it in and out, and the disassembly and assembly operations are also simpler. Of course, in other embodiments, the limiting member 26 can also be a pin, with multiple pin holes provided on the limiting rod 21, and the pin is inserted into one of the pin holes to achieve the limiting assembly of the limiting rod 21.

[0028] Furthermore, to prevent the first screw 210 from deflecting during use, in this embodiment, the connecting stiffener 4 of the station plate 2 forms a circumferential limit on the first nut 212. Specifically, two straight lines are cut out on both sides of the first nut 212, and its cross-section is similar to a rectangle. The shape of the first through hole 6 of the connecting stiffener 4 is adapted to the cross-section of the first nut 212, thereby forming a circumferential limit on the first nut 212.

[0029] Preferably, in the initial state, i.e. when no one is standing, the compression spring 24 has a certain amount of compression, so that when the operator stands on the platform 2, the platform 2 has good support strength, reducing or eliminating the initial downward movement distance of the platform 2.

[0030] Specifically, the first bushing 22 has an abutment boss (defined as the first abutment boss 221) extending radially outward from its outer periphery, and the second bushing 23 has an abutment boss (defined as the second abutment boss 231) extending radially outward from its outer periphery. The compression spring 24 is sleeved on the outer periphery of the first bushing 22 and the second bushing 23. The first end of the compression spring 24 abuts against the first abutment boss 221 of the first bushing 22, and the second end of the compression spring 24 abuts against the second abutment boss 231 of the second bushing 23. This arrangement allows for stable installation of the compression spring 24, and the external placement of the compression spring 24 does not affect the direct contact between the first bushing 22 and the second bushing 23.

[0031] Meanwhile, to avoid rigid contact between the first bushing 22 and the second bushing 23, in this embodiment, the first bushing 22 is fitted with an elastic buffer block 25 at its end facing the second bushing 23, and a groove is formed at the end of the first bushing 22 facing the second bushing 23, into which the elastic buffer block 25 is embedded; the second bushing 23 corresponds to the elastic buffer block 25 on the first bushing 22; when the distance between the first bushing 22 and the second bushing 23 decreases to zero, the second bushing 23 collides with the elastic buffer block 25 on the first bushing 22, providing a good buffering effect. Of course, in other embodiments, the position of the elastic buffer block 25 can be set on the second bushing 23. Specifically, the elastic buffer block 25 can be made of a material with a certain degree of elasticity and buffering, such as a rubber block.

[0032] The fixed abutment part 10 is fixedly assembled. In this embodiment, the fixed abutment part 10 includes a second screw 11 and two fixing nuts 12. The frame 1 has a mounting hole 1'. The second screw 11 passes through the mounting hole 1' of the frame 1. The two fixing nuts 12 are respectively screwed onto the second screw 11 and clamp and fix the frame 1. In this way, the second screw 11 and the frame 1 are relatively fixed. At the same time, the position of the second screw 11 can be adjusted by screwing it in and out. In this way, the position of the station plate 2 in the initial state can also be adjusted.

[0033] In a further preferred embodiment, the nut of the second screw 11 (defined as the second nut 111) faces the shock-absorbing part 20, that is, the first nut 212 abuts against the second nut 111. In this way, the second nut 111 is externally mounted, and the second screw 11 can be directly disassembled or adjusted using tools such as screwdrivers, which is convenient for operation.

[0034] Of course, in other embodiments, the structure of the fixed abutment portion 10 is not limited to this. For example, the fixed abutment portion 10 can also be a component that can abut against the limiting rod 21, such as a protrusion that is directly welded and fixed to the frame 1.

[0035] Furthermore, the number of damping mechanisms is two sets, which are distributed in an axisymmetric manner. Specifically, the two sets of damping mechanisms are located in the middle of the two hinge members 30, and are arranged symmetrically about the central axis of the station plate 2. This results in more uniform and stable force distribution. Of course, in other embodiments, the number and position of the damping mechanisms can be selected according to actual conditions. For example, if there is only one damping mechanism, it can be located at the central axis of the station plate 2.

[0036] This embodiment also provides a storage vehicle, which includes at least the aforementioned shock-absorbing storage platform; it is very suitable for uneven road surfaces.

[0037] Although the present invention has been specifically shown and described in conjunction with preferred embodiments, those skilled in the art should understand that various changes in form and detail may be made to the present invention without departing from the spirit and scope of the present invention as defined in the appended claims, and all such changes shall be within the scope of protection of the present invention.
