Problems solved by technology

[0003] When it is necessary to manually move the AGV (Automated Guided Vehicle, automatic guided transport vehicle), if the driving wheel is separated from the ground, the motor reducer will provide greater resistance, which is not conducive to manually moving the AGV. At the same time, when manually moving the AGV, if The motor reducer follows the rotation, which will damage the motor to a certain extent and reduce the service life of the motor
[0004] Some of the existing AGV drive suspension modules do not have a lifting mechanism, so that the suspension drive module cannot be lifted, making it very difficult to manually move the AGV; some have an electric lifting mechanism. The lifting function of the suspension drive components cannot be realized when the AGV is powered off

Embodiment 1

[0039] Such as figure 1 As shown, a suspension drive module with a lifting mechanism in this embodiment includes:

[0040] A lifting mechanism, which includes a screw mandrel 202, the bottom of which is equipped with a first flange 201;

[0041] The suspension drive mechanism includes a spring 103, the spring 103 is covered with a second flange 104, and the second flange 104 is arranged above the first flange 201 and contacts;

[0042] When the screw mandrel moves upward, the first flange 201 moves upward along with the screw mandrel, and at the same time the first flange 201 drives the second flange 104 to move upward, so that the suspension driving mechanism rises and the driving wheel 110 leaves the ground; When the screw mandrel moves downward, the first flange 201 moves downward along with the screw mandrel, and the second flange 104 moves downward under the action of its own gravity and spring force, so that the suspension driving mechanism descends.

[0043] Such as ...

Embodiment approach

[0049] As an implementation manner, the screw nut 205 is installed on the screw nut fixing base 203 , and the screw nut fixing base 203 is installed on the lifting mechanism mounting part 204 .

[0050] As an embodiment, the suspension drive mechanism also includes a guide rod 111, the upper end of the guide rod 111 is provided with an opening, and the spring 103 is arranged in the opening; the lower end of the guide rod 111 is connected to the motor reducer 109; The outer 111 of the guide rod is also sleeved with an oil-free bush 113, and the guide rod reciprocates up and down along the oil-free bush under the driving action of the motor reducer.

[0051] Specifically, in the suspension driving mechanism, the motor reducer 109 is installed on the motor reducer fixing part 115, and the lower end of the guide rod 111 is connected with the motor reducer fixing part 115 through the rotating positioning pin 116, and the two can rotate relatively while guiding The rod 111 can recip...

Embodiment 2

[0059] This embodiment provides an automatic guided transport vehicle, which includes the suspension driving module with a lifting mechanism as described in Embodiment 1.

[0060] The automatic guided transport vehicle in this embodiment includes a suspension drive module with a lifting mechanism, which can facilitate manual movement of the automatic guided transport vehicle and protect the motor at the same time.

Abstract

The invention provides a suspension driving module with a lifting mechanism and an automatic guide transmission vehicle. The suspension driving module with the lifting mechanism comprises a lifting mechanism and a suspension driving mechanism; the lifting mechanism comprises a lead screw; a first flange plate is installed at the bottom of the lead screw; the suspension driving mechanism comprisesa spring; the spring is sleeved with a second flange plate; the second flange plate is arranged above the first flange plate and makes contact with the first flange plate; when the lead screw moves upwards, the first flange plate moves upwards along with the lead screw, and meanwhile the first flange plate drives the second flange plate to move upwards, so that the suspension driving mechanism ascends, and driving wheels leave the ground; and when the lead screw moves downwards, the first flange plate moves downwards along with the lead screw, and the second flange plate moves downwards underthe action of the gravity of the second flange plate and the elastic force of the spring, so that the suspension driving mechanism descends.

Description

technical field [0001] The invention belongs to the field of automatic control equipment, and in particular relates to a suspension drive module with a lifting mechanism and an automatic guided transport vehicle. Background technique [0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art. [0003] When it is necessary to manually move the AGV (Automated Guided Vehicle, automatic guided transport vehicle), if the driving wheel is separated from the ground, the motor reducer will provide greater resistance, which is not conducive to manually moving the AGV. At the same time, when manually moving the AGV, if The motor reducer follows the rotation, which will damage the motor to a certain extent and reduce the service life of the motor. [0004] Some of the existing AGV drive suspension modules do not have a lifting mechanism, so that the suspension drive module cannot be lifted,...
