Description

Technical Field

[0001] This utility model relates to the field of loading and unloading technology, and in particular to a first degree of freedom component, an angle adjustment mechanism, and a loading and unloading vehicle. Background Technology

[0002] Existing loading and unloading vehicles consist of multiple conveyor belts. Although the first and second conveyor belts are rotatably connected, the first conveyor belt can only rotate relative to the second conveyor belt along the X-axis. It cannot directly drive the first conveyor belt to rotate relative to the second conveyor belt along the Y-axis. When it is necessary to adjust the height of the first conveyor belt relative to the object to be transported, the first and second conveyor belts can only be adjusted as a whole by a single motor. It is not possible to adjust the height of the first conveyor belt individually, which limits the application scenarios and prevents flexible height adjustment. Utility Model Content

[0029] Reference Figure 1 and Figure 3 This embodiment is the first embodiment of the utility model. This embodiment provides a first degree of freedom component 100, including a first driving unit 101, a first driving member 102, a connecting member 104 and a first driven member 103.

[0030] Specifically, in this embodiment, the first drive unit 101 is a motor, and the first degree of freedom component 100 also includes a mounting plate 106. There are two mounting plates 106, which are arranged parallel to each other and form a mounting space 107 between them. The first drive unit 101 is disposed in the mounting space 107. The output shaft of the first drive unit 101 passes through the mounting plate 106, and the first active member 102 is disposed on the output shaft of the first drive unit 101. The output shaft of the first drive unit 101 drives the first active member 102 to rotate synchronously.

[0031] Preferably, the first driven member 103 is rotatably mounted on the mounting plate 106, and the two ends of the connecting member 104 are respectively connected to the first driving member 102 and the first driven member 103.

When the output shaft of the first driving unit 101 drives the first driving member 102 to rotate, the first driving member 102 drives the connecting member 104 to move, and the connecting member 104 further drives the first driven member 103 to rotate. That is, the first driving member 102 drives the first driven member 103 to rotate around its own rotation axis through the connecting member 104.

[0032] Example 2

[0033] Reference Figures 1-6 This embodiment is the second embodiment of the utility model, and this embodiment is based on embodiment 1.

[0034] Specifically, in this embodiment, the connecting member 103 is in the shape of a long rod. Both the first driving member 102 and the first driven member 103 are rotatably connected to the connecting member 104. In this embodiment, the two ends of the connecting member 103 are rotatably connected to the first driving member 102 and the first driven member 103 respectively, which can reduce friction loss during the transmission of force.

[0035] Preferably, both the first driving member 102 and the first driven member 103 include a connecting portion 105. The connecting portion 105 extends in a direction away from the rotation axis of the first driving member 102 or the first driven member 103. The main body of the first driving member 102 and the first driven member 103 is annular in shape, and the main body and the connecting portion 105 are integrally formed. In this embodiment, the connecting portion 105 is cam-shaped, and the tip of the cam-shaped connecting portion 105 is set in a direction away from the rotation axis of the first driving member 102 or the first driven member 103.

[0036] Furthermore, both sides of the cam-shaped connecting portion 105 are tangentially connected to the main body of the first driving member 102 or the first driven member 103, and the lengths of the two sides of the connecting portion 105 connected to the first driving member 102 are not equal. In this embodiment, the connecting portion 105 of the first driving member 102 and the connecting portion 105 of the first driven member 103 are arranged facing each other.

[0037] Example 3

[0038] This embodiment is the second embodiment of the utility model. This embodiment is basically the same as embodiment 2. The difference is that although the connecting part 105 also extends in a direction away from the rotation axis of the first driving member 102 or the first driven member 103, the connecting part 105 in this embodiment is triangular in shape, and one tip of the triangular connecting part 105 is set in a direction away from the rotation axis of the first driving member 102 or the first driven member 103.

[0039] Preferably, both sides of the triangular connecting portion 105 are tangentially connected to the main body of the first driving member 102 or the first driven member 103. The included angle between these two sides is the tip of the connecting portion 105 away from the rotation axis of the first driving member 102 or the first driven member 103. In this embodiment, the lengths of the two sides of the connecting portion 105 connected to the first driving member 102 or the first driven member 103 are equal, that is, the shape of the connecting portion 105 in this embodiment is an isosceles triangle.

[0040] Example 4

[0041] Reference Figures 1 to 8 This embodiment is the fourth embodiment of the utility model, and it is based on the above embodiments. This embodiment provides an angle adjustment mechanism, including the first degree-of-freedom component 100 and the second degree-of-freedom component 200 described above.

[0042] Specifically, the first degree of freedom component 100 is used to install the second conveyor belt 400, the second degree of freedom component 200 is used to install the first conveyor belt 300, the first driven member 103 of the first degree of freedom component 100 is connected to the second degree of freedom component 200 in a transmission connection, and in use, the object is transmitted to the second conveyor belt 400 via the first conveyor belt 300.

[0043] The first degree-of-freedom component 100 is used to drive the second degree-of-freedom component 200 to rotate around the rotation axis of the first follower 103. That is, the first degree-of-freedom component 100 can drive the second degree-of-freedom component 200 to rotate around the X-axis, while the second degree-of-freedom component 200 itself can rotate along the Y-axis. By integrating the first degree-of-freedom component 100 and the second degree-of-freedom component 200, the angle adjustment mechanism has bidirectional rotation capability along the X-axis and Y-axis, breaking through the traditional single degree-of-freedom limitation.

[0044] Preferably, the second degree of freedom component 200 includes a second drive unit 201, a second driving member 202, and a second driven member 203; wherein, in this embodiment, the second drive unit 201 is a motor, the second driving member 202 is connected to the output shaft of the second drive unit 201 via a belt drive, and the second driving member 202 is sleeved on the first driven member 103, and the second driving member 202 can rotate relative to the rotation axis of the first driven member 103.

[0045] The second driven member 203 is connected to the second driving member 202 in a transmission manner. The rotation axis of the second driven member 203 is perpendicular to the rotation axis of the second driving member 202. In this embodiment, the second driving member 202 and the second driven member 203 are a pair of meshing bevel gears. Through the meshing of the second driving member 202 and the second driven member 203, when the second driving member 202 rotates, it drives the second driven member 203 to rotate.

[0046] Preferably, the second degree of freedom component 200 further includes a mounting block 204 disposed on the second follower 203. The mounting block 204 rotates synchronously with the second follower 203. The mounting block 204 is used to mount the first conveyor belt 300. When the second follower 203 rotates around its own axis of rotation, it drives the mounting block 204 and the first conveyor belt 300 to rotate synchronously around the X-axis.

[0047] Preferably, the first degree of freedom component 100 further includes a first limiting member 205 and a first locking member 208, wherein the first limiting member 205 is coaxially arranged with the first driven member 103 and rotates synchronously; the first limiting member 205 rotates relative to the first locking member 208, and the first locking member 208 is provided with a first locking groove 208a. The rotation path of the first limiting member 205 is located in the first locking groove 208a. When the first driven member 103 rotates clockwise or counterclockwise by a predetermined angle, the first locking groove 208a of the first locking member 208 abuts against the first limiting member 205 to restrict the first driven member 103 from continuing to rotate in the same direction. The first limiting member 205 prevents the first driven member 208 from over-rotating and avoids overload damage to the mechanical structure.

[0048] Furthermore, the second degree of freedom component 200 also includes a second limiting member 206 and a second locking member 209. The second limiting member 206 is coaxially arranged with the mounting block 204 and rotates synchronously. The second limiting member 206 rotates relative to the second locking member 209. The second locking member 209 is provided with a second locking groove 209a. The rotation path of the second limiting member 206 is located in the second locking groove 209a. When the mounting block 204 rotates clockwise or counterclockwise by a predetermined angle, the second locking groove 209a of the second locking member 209 restricts the mounting block 204 from continuing to rotate in the same direction by abutting against the second limiting member 206, thus avoiding excessive rotation.

[0049] Example 5

[0050] This embodiment, based on the above embodiments, provides a loading and unloading vehicle with an angle adjustment mechanism. Integrating the angle adjustment mechanism into the loading and unloading vehicle achieves a modular design, facilitating installation and maintenance, while also expanding the vehicle's functionality to suit various logistics scenarios. Integrating the angle adjustment mechanism into the loading and unloading vehicle enables multi-degree-of-freedom independent adjustment of the first conveyor belt 300, significantly improving loading and unloading efficiency and scenario adaptability.

[0051] Based on the above, the beneficial effects of this utility model are as follows: by setting the first degree of freedom component 100 to realize the rotation of the first conveyor belt 300 along the X-axis direction, and by setting the second degree of freedom component to realize the rotation of the first conveyor belt 300 along the Y-axis direction, the first conveyor belt can be satisfied to perform degrees of freedom in both the X and Y directions, thereby improving the overall flexibility.
