[0054] The first fixed shaft 17 is arranged on the displacement compensation arm 14, and the second fixed shaft 18 is arranged on the lifting arm 13, one of the first fixed shaft 17 and the second fixed shaft 14 is rotatably connected to the main body of the lifting driving element 15, and the other of the first fixed shaft 17 and the second fixed shaft 18 is rotatably connected to the driving rod of the lifting driving element 15;

[0055] Specifically, in this embodiment, the lifting driving element 15 is preferably an electric push rod, the main body of the electric push rod is penetrated by the first fixed shaft 17, the main body of the electric push rod can rotate relative to the first fixed shaft 17, and the end of the driving rod of the electric push rod is penetrated by the second fixed shaft 18, and the driving rod of the electric push rod can rotate relative to the second fixed shaft 18.

[0056] In addition, one end of the posture adjusting arm 12 is hinged to the framework 10, and the other end is connected to the mounting seat 16 and hinged to the end of the lifting arm 13, and when the lifting driving element 15 controls the lifting or lowering of the lifting arm 13, the posture adjusting arm 12 can adjust the swinging posture of the lifting arm 13, so that the end of the lifting arm 13 close to the bearing seat 11 is always in a horizontal state, so that when the lifting arm drives the bearing seat to lift or lower, the bearing seat 11 is always in a horizontal state, and does not tilt.

[0057] Further, with reference to Figure 1 , Figure 3 , Figure 4, the mounting seat 16 is provided with a first mounting portion 161 and a second mounting portion 162, the first mounting portion 161 is provided with a first rotating shaft 163, and the second mounting portion 162 is provided with a second rotating shaft 164; the end of the lifting arm 13 and the attitude adjusting arm 12 is hinged to the first rotating shaft 163, and the lifting arm 13 and the displacement compensation arm 14 are hinged to the second rotating shaft 164, wherein the hinging points of the first rotating shaft 163 and the second rotating shaft 164 and the lifting arm 13 are not coincident, and in the embodiment, the hinging point of the first rotating shaft 163 and the lifting arm 13 is located at the end of the lifting arm 13, and the hinging point of the second rotating shaft 164 and the lifting arm 13 is located between the end point and the center point of the lifting arm 13.

[0058] In addition, the end of the lifting arm 13 away from the attitude adjusting arm 12 is hinged to the bearing seat 11, the skeleton 10 is provided with a third rotating shaft 101 and a fourth rotating shaft 102, the end of the displacement compensation arm 14 away from the lifting arm 13 is hinged to the third rotating shaft 101, and the end of the attitude adjusting arm 12 away from the lifting arm 13 is hinged to the fourth rotating shaft 102.

[0059] The lifting structure of the application has the following specific principles in actual use:

[0060] With reference to Figure 1 , Figures 6 to 8 , when the bearing seat 11 rises, the driving rod of the lifting driving element 15 extends, the end of the lifting arm 13 close to the bearing seat 11 is lifted, the displacement compensation arm 14 and the attitude adjusting arm 12 hinged to the lifting arm 13 also swing together, in the running process, the bearing seat 11 is continuously and gradually lifted, since the lifting driving element 15 adopts the inclined pushing mode to push, from the mechanical point of view, the pushing force of the lifting driving element 15 can be decomposed into horizontal pushing force and longitudinal pushing force, after the horizontal pushing force is applied to the lifting arm 13, the lifting arm 13 will produce horizontal extension displacement, which will inevitably drive the bearing seat 11 at the end of the lifting arm 13 to produce horizontal displacement, at the same time, after the longitudinal pushing force is applied to the lifting arm 13, the lifting arm 13 will produce longitudinal lifting displacement, which will drive the bearing seat 11 at the end of the lifting arm 13 to produce lifting displacement, thereby realizing the lifting action of the bearing seat 11, in the lifting process of the bearing seat 11, in order to reduce the horizontal movement amplitude of the bearing seat 11, the displacement compensation arm 14 is hinged between the skeleton 10 and the lifting arm 13, after the lifting driving element 15 is pushed out, the displacement compensation arm 14 hinged to the lifting arm 13 will swing, the swinging direction of the displacement compensation arm 14 is opposite to the horizontal movement direction of the lifting arm 13 and the bearing seat 11, in the process of the reverse swinging of the displacement compensation arm 14, the horizontal displacement of the bearing seat 11 can be compensated, thereby reducing the horizontal movement amplitude of the bearing seat 11 in the lifting process, similarly, when the lifting driving element 15 drives the bearing seat 11 to descend, the displacement compensation arm 14 can also play a role in horizontal displacement compensation;

[0061] In addition, the first fixing shaft 17 is arranged on the displacement compensation arm 14, the second fixing shaft 18 is arranged on the lifting arm 13, one of the first fixing shaft 17 and the second fixing shaft 14 is rotationally connected with the main body of the lifting drive 15, the other of the first fixing shaft 17 and the second fixing shaft 18 is rotationally connected with the driving rod of the lifting drive 15, the first fixing shaft 17 and the second fixing shaft 18 are mainly used for mounting the lifting drive 15 (in this embodiment, an electric push rod is adopted, which will not be described below), after the first fixing shaft 17 and the second fixing shaft 18 are connected at two ends of the lifting drive 15, linkage of the displacement compensation arm 14 and the lifting arm 13 can be realized, since the two ends of the lifting drive 15 are rotationally connected with the first fixing shaft 17 and the second fixing shaft 18 respectively, the lifting drive 15 can conveniently adjust the mounting angle of itself, specifically, after the lifting drive 15 is pushed out, the displacement compensation arm 14 hinged with the lifting arm 13 will swing, the swinging direction of the displacement compensation arm 14 is opposite to the horizontal moving direction of the lifting arm 13 and the bearing seat 11, during the reverse swinging of the displacement compensation arm 14, the first fixing shaft 17 drives the lifting drive 15 to swing reversely, the lifting drive 15 drives the lifting arm 13 to swing towards the displacement compensation arm 14 through the second fixing shaft 18, so that the horizontal displacement compensation function of the bearing seat 11 at the end of the lifting arm 13 is further realized, thereby reducing the horizontal moving range of the bearing seat 11 during lifting.

[0062] In this embodiment, the posture adjusting arm 12 can ensure that the lifting arm 13 keeps a stable swinging posture during lifting through the unique connection mode and structural design, so that the bearing seat 11 is always in a horizontal state. Specifically, one end of the posture adjusting arm 12 is hinged with the framework 10, the other end is hinged with the mounting seat 16, and the end of the lifting arm 13. The multi-hinged point design makes the posture adjusting arm 12 capable of fine-tuning the swinging posture of the lifting arm 13 during lifting.

[0063] When the lifting drive 15 pushes the lifting arm 13 to lift or lower, the lifting arm 13 will swing around the hinged point. The posture adjusting arm 12 can sense the swinging angle of the lifting arm 13 through the hinged point with the lifting arm 13, and adjust the posture of the lifting arm 13 through the swinging of itself.

[0064] The swinging direction of the posture adjusting arm 12 is opposite to the swinging direction of the lifting arm 13, and the reverse swinging can offset the tilting trend of the lifting arm 13 during lifting, so as to ensure that the end of the lifting arm 13 close to the bearing seat 11 is always in a horizontal state.

[0065] The length and angle of the posture adjusting arm 12 are designed by precise calculation to ensure that the posture adjusting arm 12 can compensate for the inclination angle of the lifting arm 13 through its swing to keep the bearing seat 11 always horizontal, regardless of the swing of the lifting arm 13 during lifting. For example, when the lifting arm 13 produces a certain inclination angle during lifting, the posture adjusting arm 12 will adjust the end position of the lifting arm 13 through its swing to restore it to a horizontal state.

[0066] In addition, the posture adjusting arm 12 is provided with a avoiding part 121 to avoid collision with other components (such as the first fixed shaft 17) during swing, ensuring that the posture adjusting arm 12 can smoothly swing and adjust.

[0067] Further, the lifting driving part 15 (such as an electric push rod) pushes the linkage of the lifting arm 13 and the displacement compensation arm 14 through an inclined pushing manner, and the specific principle is as follows:

[0068] Decomposition of inclined pushing force: the pushing force of the lifting driving part 15 can be decomposed into horizontal pushing force and longitudinal pushing force. The horizontal pushing force pushes the lifting arm 13 to produce horizontal displacement, and the longitudinal pushing force pushes the lifting arm 13 to produce longitudinal lifting displacement.

[0069] Linkage mechanism: the two ends of the lifting driving part 15 are respectively hinged with the displacement compensation arm 14 and the lifting arm 13. When the lifting driving part 15 is pushed out, the displacement compensation arm 14 and the lifting arm 13 swing at the same time to realize the lifting and horizontal displacement compensation of the bearing seat 11.

[0070] The displacement compensation arm 14 compensates for the horizontal displacement of the bearing seat 11 through its swing direction opposite to that of the lifting arm 13, and the specific principle is as follows:

[0071] Swing compensation: when the lifting arm 13 produces horizontal displacement, the displacement compensation arm 14 offsets the horizontal displacement of the lifting arm 13 through reverse swing, thereby reducing the horizontal movement amplitude of the bearing seat 11, or even controlling the horizontal movement amplitude of the bearing seat 11 to tend to zero.

[0072] In addition, the displacement compensation arm 14 and the lifting arm 13 are hinged through the second rotating shaft 164 to ensure that they swing synchronously during lifting, improving the stability of the lifting structure.

[0073] Further, with reference to Figure 4 , Figure 5The lifting arms 13 are provided in multiple groups, and adjacent lifting arms 13 are hinged through first linkage rocker arms 131. The displacement compensation arms 14 are provided in multiple groups, and adjacent displacement compensation arms 14 are hinged through second linkage rocker arms 141. When the lifting driving member 15 controls the lifting of the bearing seat 11, the lifting arms 13 and the hinged displacement compensation arms 14 will also swing. The multiple groups of swinging lifting arms 13 are synchronously linked through the first linkage rocker arms 131, and the multiple groups of swinging displacement compensation arms 14 are synchronously linked through the second linkage rocker arms 141, so that the overall strength of the entire lifting structure can be improved.

[0074] It should be noted that in the embodiment, the lifting arms 13 and the displacement compensation arms 14 on one side below the bearing seat 11 are both provided in two groups. One lifting arm 13 and one displacement compensation arm 14 are hinged through the second rotating shaft 164, and the free ends of the other lifting arm 13 and the other displacement compensation arm 14 are hingedly connected. The hinged point can be separated from the second rotating shaft 164. The advantage of this design is that the other lifting arm 13 and the other displacement compensation arm 14 that are hingedly connected after being separated from the second rotating shaft 164 have a large degree of rotational freedom.

[0075] Further, the posture adjusting arm 12 is provided with an avoiding portion 121 corresponding to the first fixed shaft 17. The avoiding portion 121 is configured to avoid the posture adjusting arm 12 from being in contact with the first fixed shaft 17 during rotation. In the embodiment, the avoiding portion 121 is designed as an arc-shaped opening structure. During the lifting process of the entire lifting structure, the displacement compensation arm 14 swings, and the first fixed shaft 17 also swings together. The arc-shaped opening structure of the avoiding portion 121 can form an avoiding space for the first fixed shaft 17, so as to prevent the swinging first fixed shaft 17 from being in contact with the posture adjusting arm 12.

[0076] Further, the lifting arms 13 are located on both sides of the lifting driving member 15, and each lifting arm 13 is provided with a corresponding displacement compensation arm 14, so that the stability during lifting can be improved.

[0077] Further, the lifting structure of the present application is arranged at a single side position below the bearing seat 11, so that the space between the framework 10 and the bearing seat 11 can be increased, and the space can be effectively utilized. Embodiment 2

[0078] Reference Figures 9 to 11 Based on the same technical concept, the embodiment of the present application provides a scooter 200. The scooter 200 of the embodiment includes the lifting structure 100 in the above-mentioned embodiment 1, a seat 20, and wheels 21. At least one wheel 21 is provided with an electric motor 22. The seat 20 is installed on the bearing seat 11 of the lifting structure 100, and the wheels 21 are installed on the framework 10 of the lifting structure 100.

[0079] The scooter 200 in the embodiment has the technical effects of the lifting structure 100, and when the lifting structure 100 controls the lifting of the seat 20 of the scooter 200, the lifting structure 100 can realize stepless speed regulation, and the lifting is coherent and without jamming. In addition, the scooter 200 has the front-back displacement compensation function and the seat inclination posture adjustment function during the lifting of the seat 20. Moreover, the lifting structure 100 is arranged at a single side position below the seat 20, and the available space below the seat 20 is large.

[0080] With reference to Figure 12 When the seat 20 of the scooter 200 is lifted by the lifting structure 100, the center axis of the seat 20 is S1, and when the seat 20 is lowered by the lifting structure 100, the center axis of the seat 20 is S2. It is found through comparison that the distance Δd between the center axis S1 and the center axis S2 is very small, and Δd is less than 30 mm. This indicates that the lifting structure 100 has a good horizontal displacement compensation effect during the lifting of the seat 20, and the front-back displacement of the seat 20 during the lifting is very small, and the user experience is good.

[0081] The scooter 200 is provided with a control member for controlling the opening and closing of the lifting driving member 15. The control member is a remote controller or an electric button arranged at one side of the seat. After the control member controls the lifting driving member 15 to start, the lifting structure 100 can drive the seat 20 to be adjusted in height steplessly, so that the height position of the seat 20 can be set at will according to needs, and the operation is convenient.

[0082] In summary, the real-time adjustment of the posture adjustment arm 12 ensures that the bearing seat 11 always remains horizontal during the lifting. The reverse swing of the displacement compensation arm 14 reduces the horizontal movement amplitude of the bearing seat 11 during the lifting.

[0083] The plurality of lifting arms 13 and displacement compensation arms 14 are synchronously linked through the linkage rocker arm, and the overall strength of the lifting structure is improved.

[0084] The lifting structure 100 is arranged at a single side position below the bearing seat 11, and the available space between the framework 10 and the bearing seat 11 is increased. The lifting driving member 15 adopts stepless speed regulation, and the lifting process is coherent and stable.
