[0037] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, 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 part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the invention claimed for protection, but merely represents the selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0038] Refer to the attached Figure 1 As shown, a semi-automatic tree climbing machine comprises a left foot drive assembly 1, a right foot drive assembly 2 and a power supply unit 11 for powering the semi-automatic tree climbing machine, the left foot drive assembly 1 and the right foot drive assembly 2 both comprise a mounting frame 3, a foot collapse plate 4, a passive support wheel 5, an active support wheel 6, a reduction motor 7, a descending switch 8 and an ascending switch 9. In this embodiment, the descending switch 8 and the ascending switch 9 are both push-button switches; the foot collapse plate 4 is fixed to the mounting frame 3, and a passive support wheel 5 and an active support wheel 6 are respectively arranged on the side walls of the mounting frame 3, the passive support wheel 5 and the active support wheel 6 are located at the two ends of the same side of the mounting frame 3, and a reduction motor 7 for driving the active support wheel 6 to rotate is installed on the other side of the mounting frame 3, wherein the active support wheel 6 is rotatably connected to the mounting frame 3 through a bearing, and the output shaft of the reduction motor 7 is connected to the active support wheel 6; the active support wheel 6 is connected to the output shaft of the reduction motor 7, and when the reduction motor 7 does not rotate, the active support wheel 6 is stuck and does not move, that is, the active support wheel 6 will not rotate under the action of external force during use.

[0039] In this embodiment, a power supply unit 11 is installed on the mounting frame 3 of the left foot driving assembly 1 and the right foot driving assembly 2; wherein the power supply unit is a storage battery.

[0040] The active support wheels 6 on the left foot driving assembly 1 and the right foot driving assembly 2 are located on the opposite side walls of the two mounting frames 3. A descending switch 8 and an ascending switch 9 are arranged on the footrest surface of the footrest board 4. In this embodiment, the descending switch 8 is located at the sole stepping position of the footrest board 4, and the ascending switch 9 is located at the heel stepping position of the footrest board 4. The descending switch 8 and the ascending switch 9 are electrically connected to the reduction motor 7 through a control unit; wherein, the control unit can be a single chip microcomputer.

[0041] The above-mentioned passive supporting wheel 5 includes a rod body 51 and a roller 52. The rod body 51 is V-shaped, and the concave side of the rod body 51 faces the active supporting wheel 6. Rollers 52 are installed on the two straight sides of the rod body 51, and the rollers can roll on the rod body. One end of the rod body 51 is fixed to the mounting plate, and the mounting plate is installed on the mounting frame 3 by bolts and nuts; wherein, the arrangement of the roller 52 structure on the passive supporting wheel 5 facilitates the lifting and lowering of the driving component.

[0042] When in use, the passive support wheel 5 and active support wheel 6 of the drive assembly are placed on the tree trunk in a manner such that the left foot drive assembly 1 is on top and the right foot drive assembly 2 is on the bottom. When a person steps on the drive assembly to use it, the active support wheel 6 and the passive support wheel 5 exert force on the tree trunk, and the overall gravity reacts to the friction support of the two wheels through the trunk. The supporting friction force is proportional to the overall gravity of the system, and no other additional force is required for the change in gravity. The user can control the reduction motor 7 to rotate forward and reverse through the descending switch 8 and the ascending switch 9, and the reduction motor 7 drives the drive assembly to rise and fall through the active support wheel 6.

[0043] Refer to the attached Figure 1 As shown, a plurality of circular holes are laterally spaced apart on the mounting frame 3 of the left foot drive assembly 1 and the right foot drive assembly 2, and bolts pass through the circular holes and fix the passive support wheel 5 on the mounting frame 3 through nuts; wherein the passive support wheel 5 is detachably mounted on the mounting frame 3 by means of bolts and nuts; when in use, the user can install the passive support wheel 5 at different circular hole positions on the mounting frame 3 according to the size of the trunk diameter to adjust the distance between the passive support wheel 5 and the active support wheel 6, so that the drive assembly can be suitable for tree trunks of different diameters.

[0044] Refer to the attached Figure 1-2 As shown, the mounting frame 3 on the left foot drive assembly 1 is linear; the mounting frame 3 on the right foot drive assembly 2 is L-shaped, the foot plate 4 is located on the longitudinal side of the L-shaped mounting frame 3, and the active support wheel 6 and the passive support wheel 5 are located on the transverse side of the L-shaped mounting frame 3. When the left and right foot drive assemblies are mounted on a tree in an up-and-down manner, the longitudinal section of the L-shaped mounting frame 3 on the right foot drive assembly 2 can compensate for the step difference, so that the foot plates 4 on the left and right foot drive assemblies are relatively flat, making it convenient for users to stand on the left and right foot drive assemblies.

[0045] In this embodiment, the semi-automatic tree climbing machine also includes a limit sensor 10, which is installed on the mounting frame 3 of the right foot drive assembly 2; wherein, the limit sensor 10 can be a contact limit sensor (for example: a limit button) or a photoelectric limit sensor (for example: a limit infrared sensor).

[0046] When the limit sensor 10 detects the foot plate 4 on the left foot driving assembly 1, the reduction motor 7 on the right foot driving assembly 2 stops driving, and the left foot driving assembly 1 does not contact the right foot driving assembly 2 to prevent the right foot driving assembly from colliding and interfering with the left foot driving assembly during the rising process during use.

[0047] Furthermore, the down switch 8 and the up switch 9 in the left and right foot drive components include four control states:

[0048] When the descending switch 8 and the ascending switch 9 on the footrest plate 4 are pressed at the same time, the drive assembly is powered on and the reduction motor 7 does not rotate; when the descending switch 8 and the ascending switch 9 on the reduction motor 7 are pressed at the same time, the reduction motor 7 will also stop rotating.

[0049] When the descending switch 8 and the ascending switch 9 on the footrest 4 are released at the same time, the driving component is powered off; in the power-off state, the reduction motor 7 does not operate when the descending switch 8 or the ascending switch 9 is pressed alone. This arrangement can prevent the driving component from accidentally touching the descending switch 8 or the ascending switch 9 and starting the reduction motor 7 during the carrying process.

[0050] After the drive assembly is powered on, when the descending switch 8 on the footrest 4 is pressed and the ascending switch 9 is released, the reduction motor 7 on the drive assembly rotates forward;

[0051] After the drive assembly is powered on, when the descending switch 8 on the ascending switch 9 is pressed and the descending switch 8 is released, the reduction motor 7 on the drive assembly reverses.

[0052] Refer to the attached Figure 3 As shown, this embodiment also provides a method for using the semi-automatic tree climbing machine, comprising the following steps:

[0053] 1): Put the left and right foot drive assemblies into the tree trunk in the manner of the left foot drive assembly 1 on top and the right foot drive assembly 2 on the bottom (at this time, the descending switches 8 and ascending switches 9 of the left and right foot drive assemblies are both in the released state, and the left and right foot drive assemblies are in the power-off state), then step on the foot collapse plates 4 of the left and right foot drive assemblies respectively, so that the descending switches 8 and ascending switches 9 on the foot collapse plates 4 are pressed at the same time, and the left and right foot drive assemblies are powered on;

[0054] 2): Lift the left heel, release the rising switch 9 on the left foot drive assembly 1, press the falling switch 8, and the reduction motor 7 on the left foot drive assembly 1 rotates forward to move the left foot drive assembly 1 up. At this time, the weight of the human body is supported by the right foot. After the left foot drive assembly 1 rises to the required height, the left heel is stepped down, and the falling switch 8 and the rising switch 9 on the left foot drive assembly 1 are pressed at the same time, and the reduction motor 7 on the left foot drive assembly 1 stops rotating;

[0055] 3): Lift the right heel, release the rising switch 9 on the right foot drive assembly 2, press the falling switch 8, and the reduction motor 7 on the right foot drive assembly 2 rotates forward to move the right foot drive assembly 2 up. At this time, the weight of the human body is supported by the left foot. After the right foot drive assembly 2 rises to the required height, the right heel is stepped down, and the falling switch 8 and the rising switch 9 on the right foot drive assembly 2 are pressed at the same time, and the reduction motor 7 on the right foot drive assembly 2 stops rotating;

[0056] 4): Steps 2) to 3) are repeated, and the semi-automatic tree climbing machine drives the user to ascend;

[0057] 5): When you need to descend, lift the soles of both feet or lift the left and right feet alternately;

[0058] When the soles of both feet are lifted, the ascending switch 9 on the left and right foot driving assemblies is pressed, the descending switch 8 is released, and the reduction motor 7 on the left and right foot driving assemblies is reversed to drive the user to descend;

[0059] When the left and right feet are lifted alternately, the reduction motors 7 on the left and right foot drive assemblies are reversed alternately to drive the user to descend;

[0060] When the vehicle descends to the desired position, the soles of both feet are stepped down, and the reduction motor 7 stops rotating.

[0061] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations.
