In the application environment of some factory workshops, when it is necessary to use the mobile platform for climbing operations, if the working space is small, after pushing the mobile platform to a relatively narrow space, in order to lock the mobile platform, the operator needs to walk around the mobile platform in order to lock each universal wheel. However, the narrow space makes it impossible for the operator to reach the position of each universal wheel, and can only lock the two universal wheels at the position where the operator pushes the mobile platform. Therefore, the locking stability of the mobile platform is poor, and there are safety hazards. Summary of the invention

[0003] The purpose of the present application is to provide a mobile platform that can be easily locked and has high security, thereby effectively solving the deficiencies in the prior art.

[0004] To this end, an embodiment of the present application provides a mobile platform, including:

[0005] The platform body has a first end and a second end, wherein the height of the first end is higher than the height of the second end, and the second end can contact the ground;

[0006] A frame body is movably disposed on the platform body, and the frame body has a first state and a second state relative to the platform body;

[0009] When the frame is in a first state relative to the platform body, the sliding assembly on the frame contacts the ground to lift the platform body and make it movable; when the frame is in a second state relative to the platform body, the platform body is positioned so that the second end contacts the ground.

[0010] In some possible implementations, the frame can be swingably disposed on the platform body.

[0011] In some possible implementations, the drive assembly includes a first arm, which is hinged to the platform body so that the first arm has a first movable end and a second movable end, the first movable end of the first arm is hinged to the frame, and the second movable end of the first arm is detachably connected to the platform body.

[0012] In some possible implementations, the second movable end of the first arm is hinged with a second arm, the second arm is provided with a clamping piece, and the second arm swings relative to the first arm to achieve clamping or disengagement of the second arm and the platform body.

[0013] In some possible implementations, when the second arm is engaged with the platform body, the frame lifts the platform body, and the second arm applies a pulling force to the first arm.

[0014] In some possible implementations, the first arm includes a first rod and a second rod, the first rod and the second rod are arranged in parallel, the middle part of the first rod and the middle part of the second rod are hinged to the platform body, and one end of the first rod and one end of the second rod are respectively hinged to both sides of the frame.

[0026] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0027] like Figure 1-Figure 3As shown, the embodiment of the present application provides a mobile platform, which assists the relevant personnel in the high-altitude operation and can be moved. In the past, the mobile platform usually has a plurality of universal wheels at the bottom, and each universal wheel can be locked or opened. After all the universal wheels are locked, the mobile platform is locked, and after all the universal wheels are opened, the mobile platform can move freely. However, the mobile platform of this structure has certain defects in practical application. For example, when it is used in a relatively narrow space, after the mobile platform is pushed into the narrow space, due to the limited space, the relevant operators cannot walk around the mobile platform, and cannot conveniently move all the universal wheels. All the universal wheels are locked, and only the two universal wheels at the position where the operator is pushing the mobile platform can be locked. That is, if the mobile platform has a head and a position, two universal wheels are arranged at the bottom of the mobile platform corresponding to the position of the head and the position corresponding to the tail respectively, and a total of four universal wheels are arranged. When the operator holds the head and pushes the mobile platform to a narrow space, since the operator cannot reach the tail of the mobile platform, only the two universal wheels at the head of the mobile platform can be locked, and the remaining two universal wheels cannot be locked, which poses a safety hazard. The mobile platform of the present application aims to achieve the convenience of safe locking of the mobile platform.

[0028] The mobile platform includes a platform body 100, a frame 200, a sliding assembly 300 and a driving assembly. The platform body 100 has a first end 101 and a second end 102. The height of the first end 101 of the platform body 100 is higher than the height of the second end 102 of the platform body 100, and the second end 102 of the platform body 100 can contact the ground. Preferably, the platform body 100 can be a frame with a certain height in the vertical direction, the top of the frame is the first end 101, and the bottom of the frame is the second end 102. When the second end 102 sits downward on the ground, it is the locked state of the platform body 100. At this time, the platform body 100 sits directly downward on the ground with high stability.

[0029] In some embodiments, a plurality of supporting legs 400 are disposed at the second end portion 102 of the platform body 100, one end of the supporting legs 400 is connected to the platform body 100, and the other end of the supporting legs 400 extends in a direction away from the platform body 100, and the supporting legs 400 are intended to improve the stability of the platform body 100 when it is located on the ground. When the platform body 100 is upright, the projection of the platform body 100 in the horizontal plane is a rectangle, and a supporting leg 400 is disposed at each of the four corners of the bottom of the platform body 100. The supporting legs 400 are disposed vertically, and the top of the supporting legs 400 and the platform body 100 can be connected by welding, and the bottom of the supporting legs 400 is used to contact the ground. In this way, the platform body 100 is stably located on the ground under the action of the supporting legs 400.

[0030] The frame 200 can be movably arranged on the platform body 100, and the frame 200 has a first state and a second state relative to the platform body 100. The driving component is arranged between the platform body 100 and the frame 200, and the driving component is used to drive the frame 200 to switch between the first state and the second state. The sliding component 300 is arranged on the frame 200, and the frame 200 can slide freely on the ground through the sliding component 300.

[0031] Under the action of the driving component, when the frame 200 is in the first state relative to the platform body 100, the sliding component 300 on the frame 200 contacts the ground, and lifts the platform body 100 as a whole, so that the second end 102 on the platform body 100 is upwardly separated from the ground, that is, each supporting leg 400 is separated from the ground, so that the platform body 100 as a whole can move freely. At this time, relying on the free movement of the sliding component 300, it is convenient for the platform body 100 to move to the desired position. Under the action of the driving component, when the frame 200 is switched to the second state, the frame 200 no longer supports the platform body 100, so that the platform body 100 falls downward, so that the second end 102 of the platform body 100 contacts the ground, specifically, each supporting leg 400 at the bottom of the platform body 100 contacts the ground, so that the platform body 100 cannot move freely. The platform body 100 can be moved and locked, so under the action of the driving component, the frame 200 changes its state relative to the platform body 100, and the platform body 100 is supported by the frame 200 or the platform body 100 is put down. When the frame 200 supports the platform body 100, the platform body 100 can be moved under the action of the sliding component 300 on the frame 200, and when the frame 200 puts down the platform body 100, the platform body 100 is locked. In this way, operation can be achieved even in a narrow space, and the convenience is greatly improved. Moreover, compared with the previous method of locking each universal wheel separately, when the sliding component 300 is set to multiple universal wheels, the mobile platform does not have a situation where a universal wheel cannot be locked. Each universal wheel contacts or lifts off the ground at the same time to achieve the locking or release of the platform body 100, and the locking of the platform body 100 is safer and more convenient.

[0032] Preferably, the frame 200 is swingably disposed on the platform body 100 , and the frame 200 swings relative to the platform body 100 , and the state conversion is achieved through the swinging.

[0033] In one example, a plurality of connecting members 120 are provided on both sides of the frame 200, one end of the connecting member 120 is hinged to the frame 200, and the other end of the connecting member 120 is hinged to the platform body 100, and the connecting member 120 is rigid, so that when the frame 200 swings relative to the platform body 100, it can achieve height lifting and lowering, and at the same time, the posture of the frame 200 will not change, and the stability is higher, that is, it will not tilt while achieving lifting and lowering, and the platform body 100 can be lifted or lowered by lifting and lowering. The driving component includes a first arm 501, which is hinged to the platform body 100, and the first arm 501 has an extended length to form a lever-type structure. Preferably, the middle part of the first arm 501 is hinged to the platform body 10 0, so that the first arm 501 has a first movable end and a second movable end, the first movable end of the first arm 501 is hinged to the frame 200, and the second movable end of the first arm 501 is detachably connected to the platform body 100. In this way, by pulling the second movable end of the first arm 501, under the action of torque, the first movable end of the first arm 501 can drive the frame 200 to swing, and at the same time, under the hinge action of the connecting piece 120, the frame 200 is swung and raised. In this embodiment, the second movable end of the first arm 501 can be close to a position on the platform body 100 that is easy for the operator to reach, and the locking or releasing operation of the platform body 100 is more convenient. For example, it can be close to the part of the platform body 100 that the operator is accustomed to holding.

[0034] More preferably, the second arm 502 is hinged at the second movable end of the first arm 501, and a clamping piece is provided on the second arm 502. The second arm 502 can swing relative to the first arm 501, thereby enabling the second arm 502 to be clamped or disengaged from the platform body 100. Preferably, when the second arm 502 is clamped with the platform body 100, the frame 200 lifts the platform body 100. At this time, the second arm 502 applies a pulling force to the first arm 501. In this embodiment, the first arm 501 forms a lever. By driving the second arm 502, The second arm 502 applies a pulling force to the second movable end of the first arm 501, thereby driving the first arm 501 to rotate, so that the first movable end of the first arm 501 drives the frame 200 to swing and the movement trend is to reduce the height, that is, the frame 200 has a downward movement component relative to the platform body 100, so that the sliding assembly 300 on the frame 200 contacts the ground, and continues to apply a force to the second arm 502, so that the second arm 502 continues to pull the second movable end of the first arm 501 until the frame 200 lifts the platform body 100. 0 is lifted to lift the support foot 400 on the platform body 100 off the ground, and then the clamping piece on the second arm 502 is clamped with the component on the platform body 100 to realize the limit, and the platform body 100 can be moved freely. When the platform body 100 is moved to the specified position, the second arm 502 is pulled to disengage the clamping piece on the second arm 502 and the platform body 100, and then the second arm 502 is slowly released to make the first arm 501 slowly rotate in the opposite direction, so that the frame 200 is slowly moved relative to the platform body 100. The platform body 100 moves upward until the supporting foot 400 at the bottom of the platform body 100 touches the ground to form a limit lock. In this embodiment, in order to make the operation more labor-saving for the operator, along the lever extension direction of the first arm 501, the distance from the hinge point of the first arm 501 and the platform body 100 to the second movable end of the first arm 501 is taken as a, and the distance from the hinge point of the first arm 501 and the platform body 100 to the first movable end of the first arm 501 is taken as b, and a is more than 5 times of b. Under the action of torque, the operator can operate the lifting and lowering of the platform body 100 more labor-saving.

[0035] In some embodiments, the first arm 501 includes a first rod 5011 and a second rod 5012, the first rod 5011 and the second rod 5012 are arranged in parallel, the first rod 5011 and the second rod 5012 are parallel to each other and arranged at intervals, and a connecting beam can be arranged between the first rod 5011 and the second rod 5012 to connect the first rod 5011 and the second rod 5012, so that the first arm 501 is a rack-shaped structure with a certain length, and the middle part of the first rod 5011 and the middle part of the second rod 5012 are both hinged. On the platform body 100, the middle part of the first rod 5011 and the middle part of the second rod 5012 are respectively hinged at different positions of the platform body 100, one end of the first rod 5011 and one end of the second rod 5012 are respectively hinged at two sides of the frame 200. In this embodiment, the frame 200 is also a rack-shaped structure with a certain length. One end of the first rod 5011 and one end of the second rod 5012 are respectively hinged at two opposite sides of the frame 200, and the opposite sides are the two sides where the connecting member 120 is set.

[0036] In the above, the rack shape refers to a single-row rack-shaped structure similar to a ladder.

[0037] Preferably, the platform body 100 is a frame structure. When the platform body 100 is upright, the outer contour of the projection of the platform body 100 in the horizontal plane is a rectangle. The extension direction of the longer side of the rectangle is parallel to the swing plane of the frame 200 relative to the platform body 100. The extension direction of the longer side of the rectangle is taken as the first direction, and the swing plane of the frame 200 relative to the platform body 100 is a vertical plane, so that the length direction of the first arm 501 and the second arm 502 is also parallel to the swing plane of the frame 200. In this way, for the platform body 100, the two sides along the first direction on the platform body 100 are taken as the front and rear On both sides, the front side is taken as the holding side among the front and rear sides, that is, the operator is accustomed to pushing the platform body 100 with the holding side, and the movable end of the second arm 502 relative to the first arm 501 can be detachably connected to the holding side of the platform body 100, so that it is convenient for the operator to lock or release the platform body 100, that is, the clamping part on the second arm 502 is detachably connected to the local component at the holding side of the platform body 100, and the operation is more convenient. After pushing the platform body 100 to a narrow space, the platform body 100 can be locked after stopping, and the convenience is greatly improved.

[0038] In some embodiments, the second arm 502 includes a third rod 5023 and a fourth rod 5024, the third rod 5023 and the fourth rod 5024 are arranged in parallel, the third rod 5023 and the first rod 5011 are hinged to each other, the fourth rod 5024 and the second rod 5012 are hinged to each other, the third rod 5023 and the fourth rod 5024 are spaced apart and arranged in parallel, and a connecting beam can be set between the fourth rod 5024 and the third rod 5023 to connect the third rod 5023 and the fourth rod 5024 together, so that the second arm 502 forms a rack shape. In this embodiment, hooks 5026 are set on the third rod 5023 and the fourth rod 5024 to form a clamping piece, so as to be hooked and connected with the components on the platform body 100, and the operation is also convenient.

[0039] Preferably, a step assembly is provided on the platform body 100, and the step assembly is stepped. The step assembly connects the first end 101 and the second end 102 of the platform body 100. The first end 101 and the second end 102 are connected by the step assembly, so that it is convenient for operators to move from the second end 102 to the first end 101 through the step assembly. In this embodiment, a working surface 600 is provided at the first end 101, and the working surface 600 is used to carry operators. The working surface 600 is provided for operators to move around, so that it is convenient for operators to work at heights. In addition, a guardrail 700 with a door panel can also be provided on the working surface 600 to improve safety.

[0040] In this embodiment, the step assembly includes a load-bearing rod 801, and two groups of load-bearing rods 801 are arranged in parallel. The load-bearing rod 801 extends from the second end 102 of the platform body 100 to the first end 101 of the platform body 100. A plurality of step pedals 802 are evenly spaced between the two load-bearing rods 801. The step pedals 802 are staggered in sequence to form a stair step shape, which is convenient for operators to climb. In this embodiment, the gap between two adjacent step pedals 802 is large enough for the second arm 502 to extend into. After the second arm 502 extends between the two adjacent step pedals 802, under the action of gravity, the second arm 502 can be downwardly placed on the step pedal 802 in the middle and lower part of the two step pedals 802, and then the hook 5026 on the second arm 502 and the lowered step pedal 802 are hooked. The hook 5026 on the second arm 502 is connected with the step pedal 802, which makes it easier to lock the platform body 100. In this embodiment, the setting of the step pedal 802 not only enables the operator to climb, but also enables the second arm 502 and the first arm 501 to be locked in a limited position. Moreover, the side of the platform body 100 where the step assembly is located is also convenient for the operator to hold and push the platform body 100. In this embodiment, the swing plane of the second arm 502 relative to the first arm 501, the swing plane of the first arm 501 relative to the frame 200, and the plane where the load-bearing rod 801 extends are parallel to each other, which facilitates the hooking and locking of the second arm 502 with the step pedal 802. After the second arm 502 and the step pedal 802 are hooked, the second arm 502 is subjected to tension.

[0041] In one example, the sliding assembly 300 can be a ball bearing, a track, etc. Preferably, the sliding assembly 300 includes a plurality of rollers, each of which is respectively connected to the bottom of the frame 200. After the frame 200 lifts the platform body 100, the platform body 100 is conveniently pushed under the action of the plurality of rollers. The rollers can be a universal wheel structure to facilitate steering.
