Embodiment 1

[0059] Such as Figure 1 to Figure 14 As shown, it is a preferred structure of the object compartment opening and closing device for preventing misopening according to the present invention.

[0060] Such as Figure 6 As shown, the object compartment opening and closing device for preventing misopening includes a crank rocker mechanism 10 , an actuator 20 and a limit assembly 30 . The actuator 20 is drivingly connected with the crank-rocker mechanism 10; the crank-rocker mechanism 10 is connected with the hatch 40 of the item compartment 50 and drives the hatch 40 to move; the limit assembly 30 is used to prevent the hatch 40 from After being closed, it is artificially opened.

[0061] The object compartment opening and closing device of the present invention can be applied to a service robot, so that the hatch cover of the item compartment of the robot can be automatically opened and closed; at the same time, the limit assembly can prevent the hatch cover from being opened ...

Embodiment approach

[0080] The first type, such as Figure 9 As shown, when the crank 11 is at the first position, the crank rocker mechanism 10 abuts against the limit assembly 30 on one side, and the reverse swing angle of the crank 11 is zero, so that the hatch 40 is completely locked.

[0081] The second type, such as Figure 13 As shown, the limit assembly 30 is set at a distance from the crank-rocker mechanism 10; the acting force causes the crank 11 to reversely swing from the first position to the third position. When the crank 11 is at the third position, the crank-rocker mechanism 10 abuts against the limiting assembly 30 to offset the force, and the hatch 40 exposes a part of the opening of the item compartment 50 .

[0082] Specifically, the present embodiment 1 illustrates the present invention with a preferred crank 11 rocker 13 structure, specifically as follows:

[0083] Such as Figure 7 As shown, the crank 11 includes a crank shaft 111, and the crank shaft 111 is a prolate p...

Embodiment 2

[0093] The structure and working principle of the object compartment opening and closing device for preventing misopening described in Embodiment 2 are similar to those described in Embodiment 1. The difference is that Embodiment 2 is implemented based on the second implementation of the limiting component. The limiting assembly is set at a distance from the crank-rocker mechanism; the force causes the crank to reversely swing from the first position to the third position; when the crank is in the third position, the crank-rocker mechanism abuts against the limiting assembly In order to counteract the active force, and the hatch cover reveals a part of the opening of the item compartment.

[0094] Through the above arrangement, the hatch cover 40 can be partially opened, which also causes the crank rocker mechanism 10 to have a certain movable range. For example, the crank 11 can reversely swing at a certain angle, and the connecting rod 12 has a certain swing range. With th...

Abstract

The invention discloses an article cabin opening and closing device prevented from being opened by mistake and a service robot. The article cabin opening and closing device comprises a crank and rocker mechanism, an actuator and a limiting assembly. When a crank is located at the first position, a cabin cover is closed to cover an opening of an article cabin; and when the crank is located at the second position, the cabin cover opens the opening of the article cabin. The actuator drives the crank to swing to the second position from the first position in the forward direction and swing back tothe first position from the second position. The limiting assembly is adjacently arranged on one side of the crank and rocker mechanism. When the closed cabin cover bears external force for opening the cabin cover, the external force is converted by the crank and rocker mechanism into acting force for enabling the crank to swing from the first position in the backward direction. The crank and rocker mechanism abuts against the limiting assembly to offset the acting force, and then the cabin cover is locked. According to the article cabin opening and closing device prevented from being openedby mistake and the service robot, the actuator drives the crank and rocker mechanism to act, and then the cabin cover is driven to complete opening and closing actions. The crank and rocker mechanismis small in moment and low in noise, and the service life of the actuator can be prolonged.

Description

technical field [0001] The invention belongs to the technical field of intelligent robots, and in particular relates to an object compartment opening and closing device for preventing misopening and a service robot. Background technique [0002] With the progress and development of society, intelligent service robots are gradually replacing some human services. At present, intelligent service robots are mainly used in office buildings and hotels, mainly for voice dialogue and indoor guidance services. At this stage, intelligent service robots also have the ability to transport items to designated locations, such as food delivery and express delivery. [0003] In the process of realizing the present invention, the applicant finds that the existing products have at least the following problems: [0004] Due to the high mobility and complexity of personnel in office buildings and hotels, it is not possible to train all personnel to operate intelligent service robots. This al...
