Description

Technical Field

[0001] The present invention relates to the technical field of elevators, and particularly relates to a restraint device inside a car. Background Art

[0002] It is becoming more and more common for robots and passengers to share the elevator space. When a robot and a passenger share the elevator space, the robot may move unexpectedly, which may cause accidental injuries to the co-riding passengers. Therefore, how to avoid the unexpected movement of the robot when it shares the elevator space with passengers is a technical problem currently faced. Summary of the Invention

[0003] To solve the above technical problem, the present invention provides a restraint device inside a car, which includes a telescopic device, a restraint belt and a fixing head;

[0004] The telescopic device is fixed inside the car; the restraint belt is a flexible rope or belt, one end of which is fixed to the telescopic device, and the other end is fixed to the fixing head; the restraint belt is accommodated in the telescopic device in a winding manner, can be pulled out by an external force, and can be wound and retracted by the telescopic device when the external force is released; the restraint belt is used to fix the robot inside the car in a preset space.

[0005] Preferably, the telescopic device is fixed inside the armrest or the control box inside the car.

[0006] Preferably, the robot is fixed in the preset space by connecting the fixing head to the fixing seat on the robot.

[0007] Preferably, the restraint device further includes a plug board, which is fixed inside the car, and the robot is fixed in the preset space by connecting the fixing head to the plug board.

[0008] Preferably, the restraint device further includes an action sensing device. When the action sensing device detects that the restraint belt is pulled, the action sensing device sends a restraint device action signal to the elevator control system or the monitoring system.

[0009] Preferably, the restraint device further includes an action sensing device. When the action sensing device detects that the fixing head is connected to the fixing seat on the robot, the action sensing device sends a signal that the robot has been fixed to the elevator control system or the monitoring system.

[0010] Preferably, the restraint device further includes an action sensing device. When the action sensing device detects that the fixing head is connected to the plug board, the action sensing device sends a signal that the robot has been fixed to the elevator control system or the monitoring system.

[0011] Compared with the prior art, the present invention can provide a device for fixing the robot for passengers, so that the robot is constrained in a preset space inside the elevator car, avoiding accidental movement from causing harm to passengers. Brief Description of the Drawings

[0012] The present invention will be further described in detail below in conjunction with the drawings and specific embodiments:

[0013] Figure 1 It is a schematic structural diagram of the restraint device inside the car for Embodiment 1;

[0014] Figure 2 It is a schematic diagram of the plug board of the restraint device inside the car for Embodiment 2. Specific Embodiments

[0015] The following describes the embodiments of the present invention through specific specific examples. Those skilled in the art can fully understand other advantages and technical effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through different specific embodiments. The details in this specification can also be applied based on different viewpoints, and various modifications or changes can be made without departing from the overall design concept of the invention. It should be noted that, without conflict, the following embodiments and the features in the embodiments can be combined with each other. The following exemplary embodiments of the present invention can be implemented in many different forms and should not be construed as being limited only to the specific embodiments described herein. It should be understood that these embodiments are provided to make the disclosure of the present invention complete and thorough, and to fully convey the technical solutions of these exemplary specific embodiments to those skilled in the art.

[0016] Embodiment 1

[0017] As Figure 1 shown, this embodiment provides a restraint device inside the car, including a telescopic device 1, a restraint belt 2, and a fixed head 3;

[0018] The telescopic device 1 is fixed inside the car, such as a rope winder; the restraint belt 2 is a flexible rope or belt, one end of which is fixed to the telescopic device 1, and the other end is fixed to the fixed head 3. The fixed head 3 can be in the form of a plug, a hook, a buckle, etc.; the restraint belt 2 is accommodated inside the telescopic device 1 in a winding manner and can be pulled out by an external force, and can be wound and retracted by the telescopic device 1 when the external force is released; the restraint belt 2 is used to fix the robot inside the car in a preset space.

[0019] The telescopic device 1 can be fixed, for example, on the side part, bottom part, etc. of the car that can bear tension. For the sake of beauty, the telescopic device 1 can be fixed in a concealed position such as inside the armrest, inside the control box, etc.

[0020] One or more restraint devices of this embodiment can be provided inside the car, and the robot is fixed in a preset space by connecting the fixed head 3 to the fixed seat on the robot.

[0021] The restraint device further includes an action sensing device (not shown in the figure). When the action sensing device detects that the restraint belt is pulled, the action sensing device sends a restraint device action signal to the elevator control system or the monitoring system. Or when the action sensing device detects that the fixed head is connected to the fixed seat on the robot, the action sensing device sends a signal that the robot has been fixed to the elevator control system or the monitoring system. This enables the elevator system to know that the car is in a specific scenario mode, so as to provide necessary services or other linkage actions.

[0022] Embodiment 2

[0023] As Figure 2 shown, on the basis of Embodiment 1, the restraint device in the car of this embodiment further includes an insertion plate 4. The insertion plate 4 is fixed in the car, and the robot is fixed in the preset space by connecting the fixed head 3 to the insertion plate 4. The restraint device further includes an action sensing device (not shown in the figure). When the action sensing device detects that the fixed head is connected to the insertion plate, the action sensing device sends a signal that the robot has been fixed to the elevator control system or the monitoring system. This enables the elevator system to know that the car is in a specific scenario mode, so as to provide necessary services or other linkage actions.

[0024] The present invention has been described in detail through specific embodiments and examples above, but these do not constitute limitations to the present invention. Without departing from the principle of the present invention, those skilled in the art can also make many modifications and improvements, which should also be regarded as the protection scope of the present invention.
