[0040] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0041] In order to solve the problems of traditional lifting platforms, such as large footprint, limited installation conditions, complex structure, difficult installation and maintenance, and high cost, this application adopts a folding platform design; the platform is opened when in use and automatically folded up when not in use; when not in use, this device occupies one tenth or even less of the area of ​​a traditional lifting platform.

[0042] Reference Figure 1-20 , an electronically controlled foldable hydraulic automatic lifting platform that takes up little space and can be used in narrow spaces.

[0043] It includes: anti-tilt rails 1 on both sides, and a load-bearing platform 3 located on the inner side of the anti-tilt rails 1, which is raised and lowered by a power component 2; wherein the anti-tilt rails 1 form a limit and movement guide, and the load-bearing platform 3 is raised and lowered to form a working space to lift people and / or goods.

[0044] It is understandable that the anti-tilt rail 1 needs to be firmly and reliably fixed; preferably, a mounting plate is welded on the outer side of the anti-tilt rail 1 and fixed to the mounting surface by bolts or other connecting parts.

[0045] Furthermore, it also includes: a folding mechanism 4.

[0046] The folding mechanism 4 flips the load-bearing platform 3 to a horizontal working state and a vertical storage state.

[0047] like Figure 2 、 12 As shown, they are in the storage state (at the low and high positions respectively), basically only occupying a little more space than the thickness of the load-bearing slide rail; Figure 4 、 13 As shown, it is a working state. The area of ​​the load-bearing platform 3 is set according to the required space conditions to achieve full utilization of the effective space.

[0048] By switching and coordinating between the working state and the storage state, the platform can be installed and used in a variety of spaces, and is especially suitable for narrow spaces. It only requires the installation surface to fix the anti-tilt rail 1 and coordinate with the dimensions of the load-bearing platform 3 to complete a set of simple and reliable lifting devices.

[0049] In some embodiments, the top of the power assembly 2 is equipped with a load-bearing platform support rod 5; the load-bearing platform 3 is hingedly connected to the load-bearing platform support rod 5 to achieve swinging.

[0050] In this state, the load-bearing platform support rod 5 serves as the lifting output and provides an installation basis for the load-bearing platform 3; at the same time, it cooperates with the anti-tilt rails 1 on both sides to ensure the stability of the lifting form.

[0051] It should be noted that the load-bearing platform support rod 5 should have sufficient strength and reliability; preferably, it is made of square steel.

[0052] Among them, an articulated structure such as a hinge is used between the load-bearing platform 3 and the load-bearing platform support rod 5; it is necessary to ensure the strength and reliability of the connection.

[0053] Preferably, the outer lower edge of the load-bearing platform 3 (viewing angle in the storage state) is hinged to the upper rear edge of the load-bearing platform support rod 5; in the storage state, the load-bearing platform 3 is basically flush with the outer end surface of the load-bearing platform support rod 5, further reducing the occupied space.

[0054] In some embodiments, the folding mechanism 4 includes: a load-bearing oblique support 41 fixed on the load-bearing platform support rod 5 and extending downward to the outside; and a load-bearing hydraulic rod 42, one end of which is hinged to the load-bearing oblique support 41 and the other end is hinged to the lower end surface of the load-bearing platform 3.

[0055] See also Figure 2 、 6 The extended form of the load-bearing oblique support 41 cooperates with the load-bearing hydraulic rod 42 to realize the flipping operation of the load-bearing platform 3; and the oblique force has a good supporting effect in the working state.

[0056] It should be noted that the load-bearing oblique supports 41 and the load-bearing hydraulic rods 42 can be arranged in a group at the middle position; or, symmetrically arranged in multiple groups; depending on the cost and load-bearing requirements.

[0057] In some embodiments, the power assembly 2 is a lifting bracket.

[0058] Correspondingly, the upper end of the lifting bracket is hingedly assembled on the load-bearing platform support rod 5, and the lower end is hingedly assembled on the bottom limit frame 7.

[0059] It should be noted that the basic support system is formed by the bottom limit frame 7 and the anti-tilt rails 1 on both sides; the power assembly 2 is located in the U-shaped space covered by it.

[0060] Optionally, the length of the bottom limit frame 7 is set to be larger; the anti-tilt rails 1 on both sides are fixedly connected to the top of the two ends of the bottom limit frame 7 by welding, bolt assembly and the like.

[0061] During installation, the above three components (bottom limit frame 7 and two anti-tilt rails 1) are fixed first, and then other components are installed, which is faster and more efficient. Moreover, the basic framework has been formed in the early stage of installation, and the operation is more convenient.

[0062] In some embodiments, unlike conventional scissor or telescopic structures, a dynamic form with stronger supporting force is adopted; the lifting bracket is composed of three groups of supporting rods that cooperate with each other and are parallel within the group.

[0063] At the same time, the lifting bracket is driven to swing by the lifting hydraulic rod 8 to achieve lifting adjustment.

[0064] Correspondingly, one end of the lifting hydraulic rod 8 is rotatably assembled with the bottom limit frame 7, and the other end is rotatably assembled with the inner side of the lowest support rod.

[0065] Specifically, the first group of support rods includes: A rod 21 and B rod 22; the second group of support rods includes: C rod 23 and D rod 24; and the third group of support rods includes: E rod 25 and F rod 26.

[0066] Among them, the first and second groups of support rods are long rods of the same length; the third group of support rods are short rods.

[0067] The A-rod 21 and the C-rod 23 are arranged in an X shape, and the top ends of the A-rod 21 and the C-rod 23 are rotatably assembled with both sides of the lower end of the load-bearing platform support rod 5 respectively.

[0068] The B rod 22 and the D rod 24 are arranged in an X shape, and the lower ends of the B rod 22 and the D rod 24 are rotatably assembled with both sides of the upper end of the bottom limiting frame 7 respectively.

[0069] The above four rods constitute the basic double X-shaped structure; the third group of support rods (E rod 25, F rod 26) serves as a reinforced support system.

[0070] Specifically: the top end of the E rod 25 is assembled with the "hinge axis of the B rod 22 and the C rod 23", and the lower end is assembled with the middle axis of the D rod 24; the lower end of the F rod 26 is assembled with the "hinge axis of the A rod 21 and the D rod 24", and the top end is assembled with the middle axis of the C rod 23.

[0071] The hinged parts of the C-rod 23 , the D-rod 24 , the E-rod 25 , and the F-rod 26 form a parallelogram.

[0072] Correspondingly, the upper end of the lifting hydraulic rod 8 is rotatably assembled with the inner side of the lower end of the B rod 22; during lifting control, the lifting hydraulic rod 8 is extended and retracted to push and pull the B rod 22 to swing; thereby driving the remaining support rods to move to achieve lifting adjustment.

[0073] In the force process of this state, take the lifting state as an example: The inner side of the B rod 22 is pushed and pulled by the lifting hydraulic rod 8; during its lifting process, the angle between the B rod 22 and the C rod 23 changes, and the C rod 23 forms a lifting force on the right end of the load-bearing platform support rod 5; at the same time, the lower end of the E rod 25 hinged to the B rod 22 pulls the D rod 24 to the middle position, and the F rod 26 hinged to the C rod 23 to the middle position pulls the end of the D rod 24; the D rod 24 is lifted; at the same time, the hinge point of the D rod 24 and the F rod 26 forms a pull on the A rod 21; the A rod 21 forms a lifting force on the left end of the load-bearing platform support rod 5; thereby, the lifting of the entire load-bearing platform support rod 5 is achieved.

[0074] It should be noted that the lifting bracket composed of six rods cannot maintain absolute vertical lifting during the movement, but will deviate to both sides; therefore, it needs auxiliary positioning.

[0075] Preferably, fittings 6 are provided at both ends of the load-bearing platform support rod 5 .

[0076] At the same time, vertical sliding grooves 11 are relatively provided on the inner sides of the anti-tilt rails 1 on both sides; the outer end of the matching piece is inserted into the sliding groove 11 and slides, and the other end is slidably or telescopically matched with the load-bearing platform support rod 5.

[0077] In this state, through the cooperation between the fitting 6, the slide groove 11 and the end of the anti-tilt rail 1, the anti-tilt rail 1 can be restricted when deflecting to both sides, thereby maintaining better stability.

[0078] In some embodiments, the slide groove 11 includes a wide groove and a narrow groove that are connected to each other as one.

[0079] like Figure 5 、 15 , 16; the narrow groove extends to the inside for the fitting 6 to be placed inside.

[0080] The fitting part 6 includes a head block 61 that fits with the wide slot, and a rod body 62 connected to the head block 61 . It can be understood that the rod body 62 passes through the narrow slot and is connected to the head block 61 .

[0081] Among them, the rod body 62 is a telescopic rod, the inner end of which is fixed to the end of the support rod 5 of the load-bearing platform; Alternatively, the rod body 62 is a straight rod, the inner end of which is inserted into the support rod 5 of the load-bearing platform and slides.

[0082] Furthermore, vertical grooves are provided around the inner wall of the wide groove; when some debris enters the chute 11, the impact on normal movement is reduced; it is understandable that debris still needs to be cleaned in time after entering; the addition of vertical grooves is mainly to reduce the impact of some small debris and the impact of rainwater in the external environment.

[0083] Furthermore, an oblique opening 12 connected to the sliding groove 11 is formed on the anti-tilt rail 1 .

[0084] Please refer to Figure 2 , a plurality of inclined discharge ports 12 are arranged at intervals; when some small debris or rainwater enters the chute 11, it can be discharged outward from the inclined discharge port 12.

[0085] In some embodiments, when the rod body 62 is a straight rod, an end seal is provided at the end of the load-bearing platform support rod 5 .

[0086] The end seal comprises an end plate and a guide cylinder fixedly connected inside the end plate.

[0087] The axis of the guide cylinder is perpendicular to the end plate surface; the rod body 62 is placed in the guide cylinder to form a moving path consistent with the longitudinal axis of the load-bearing platform support rod 5.

[0088] It can be understood that the end plate has holes corresponding to the guide cylinder; during installation, the end plate is fixedly welded to the end of the support rod 5 of the load-bearing platform.

[0089] Further, such as Figure 18 、 19 As shown; the outer side of the guide cylinder is surrounded by a reinforcing rib; and the reinforcing rib touches the inner wall of the load-bearing platform support rod 5.

[0090] Furthermore, the front end of the reinforcing rib is provided with a chamfered or rounded corner.

[0091] In some embodiments, an expansion platform 31 is detachably mounted on the end of the load-bearing platform 3 .

[0092] It should be noted that, in order to ensure the strength of the load-bearing platform 3, it is composed of a frame and a panel.

[0093] like Figure 8 、 9 As shown; the expansion platform 31 is also composed of a frame and a panel; correspondingly, an insertion rod is fixedly provided on the inner side of the frame of the expansion platform 31; a socket is provided at a corresponding position of the frame of the load-bearing platform 3; the two cooperate to realize assembly.

[0094] For fixing the assembly relationship between the two, bolts can be used to penetrate the frame of the load-bearing platform 3 and insert rods, or snap-fit ​​connection can be used at the docking position, and technicians in the field can make conventional choices.

[0095] In some embodiments, the anti-tilt rail 1 of the load-bearing platform 3 is composed of multiple sections, which can be more convenient to install and can be assembled into different height strokes according to needs.

[0096] Preferably, Figure 15 As shown; the butt ends of the two anti-tilt rails 1 are provided with no less than two positioning holes; when butt-jointing, positioning pins are inserted into the positioning holes, which can achieve high-precision butt-jointing more reliably and conveniently.

[0097] The butt joint can be welded to achieve a reliable permanent connection.

[0098] It is understandable that the anti-tilt rail 1 needs to be fixed on the installation surface; such as the outer welded mounting plate form mentioned above; no additional reinforcement structure is required at the docking position; on the basis of ensuring high-precision matching, the installation of the anti-tilt rail 1 is ensured to be stable.

[0099] This device can be installed on building walls, vehicles, etc.

[0100] During installation: install the two anti-tilt rails 1 in parallel on the space wall (installation surface), and hide the load-bearing platform 3, folding mechanism 4, and power assembly 2 in the middle of the anti-tilt rail 1 to achieve extremely small space occupation, meet the needs of work, life, etc., and the installation conditions are wider; the load-bearing hydraulic rod 42 of the folding mechanism 4 is installed under the load-bearing platform 3 to achieve reliable force support; two support rods are a group, and each group is designed to be installed in parallel. The lifting height formed by the cooperation of the three groups has a larger range; the size of the support rod and the thrust of the lifting hydraulic rod 8 are set according to the required height to achieve reaching higher floors; the design of a single load-bearing hydraulic rod 42 and a single lifting hydraulic rod 8 can be selected to reduce production costs while ensuring safety.

[0101] It should be noted that this platform is controlled by a remote control, which can control the extension and retraction of the load-bearing hydraulic rod 42 and the lifting hydraulic rod 8; and preset commands can be formed, which can reach the top, land on the ground, and be stored with one button; at the same time, a suitable position is selected on the installation surface of this platform to set the button panel, as well as one-button emergency stop, etc.

[0102] Before work, if Figures 1-3 As shown; at this time, the platform is in the storage state with the smallest footprint; press the open button on the remote control or key panel, and the load-bearing hydraulic rod 42 is recovered; Figures 4-6 As shown, the load-bearing platform 3 opens and stops parallel to the ground, and people and goods enter the load-bearing platform 3; press the up button, the lifting hydraulic rod 8 pushes the support rod, and the six support rods are simultaneously forced to push the load-bearing platform 3 up; Figures 13 and 14 As shown, the platform rises to the corresponding position and stops, and people and goods go up and down.

[0103] When not working, the lifting hydraulic rod 8 is retracted to drive the lifting support rod to drop to the corresponding position and stop; the load-bearing hydraulic rod 42 pushes the load-bearing platform 3 to flip upward, retract and hide, and stop at the corresponding position to complete a set of actions; one-button descent and reset can be achieved through preset instructions, and multiple lifting actions can also be achieved according to needs.

[0104] The device occupies a small space, has a wide installation position, a simple structure, a low weight, is easy to install and maintain, is highly safe, and significantly reduces procurement and use costs.

[0105] This device can be widely used in certain specific space fields.

[0106] Automobile field: Due to the small interior area of ​​RVs and special vehicles, this device can be installed at the back of the RV. After opening or raising the roof, users can enjoy the scenery, cook, take photos, set up tents, etc., which greatly enhances the fun of RV life and increases the safety of outdoor life.

[0107] Villa or bungalow; from the ground to the porch, to the second floor, and then to the roof, it is convenient for families with disabled or elderly people, as well as for rooftop maintenance or viewing needs; new rural flat-roofed houses, from the ground to the roof for drying and viewing the scenery, and the installation plan can be flexibly formulated according to the height, opening up design space for old single buildings.

[0108] Provide broad design imagination space for tourist attractions, hotels, B&Bs, and temporary buildings.

[0109] It provides imagination space for the modification of military training grounds, fortifications, reconnaissance and troop transport vehicles.
