Detailed Description

Reference will now be made in detail to embodiments of the present application, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary only for the purpose of explaining the present application and are not to be construed as limiting the present application.

Unless otherwise specified, the front-rear direction in the present application is the longitudinal direction of the vehicle 1001, i.e., the X direction; the left-right direction is the lateral direction of the vehicle 1001, i.e., the Y direction; the up-down direction is the vertical direction of the vehicle 1001, i.e., the Z direction.

The side handrail assembly 1000 according to the embodiment of the present application will be described with reference to fig. 1 to 41, which can manually unlock the side handrail 200 and the connection handrail 100 when the passenger needs to rotate the side handrail 200, and automatically lock the side handrail 200 and the connection handrail 100 when the passenger does not need to rotate the side handrail 200, and thus, the passenger has low difficulty in operation and is convenient to use.

As shown in fig. 1 to 41, a side barrier armrest assembly 1000 according to an embodiment of the present application includes: the connecting armrest 100, the side armrest 200, the locking mechanism 300, and the drive mechanism 400.

As shown in fig. 35 and 36, the connecting handle 100 extends in the vertical direction, the upper end of the connecting handle 100 is connected to an upper handle pipe 1002 of the vehicle 1001, and the lower end of the connecting handle 100 is connected to a lower handle pipe 1003 of the vehicle 1001, so that the connecting handle 100 is stably mounted to the vehicle body. The connecting handrail 100 is made of a hard material so as to have a large structural strength and rigidity, and is used for providing a large supporting force and a large supporting force for passengers, for example, at least a part of the connecting handrail 100 is made of a metal material.

The side arm rest 200 is rotatably installed to the connection arm rest 100, and as shown in fig. 35, the side arm rest 200 is connected to a side wall of the connection arm rest 100, and an axis of the side arm rest 200 is perpendicular to an axis of the connection arm rest 100, so that the side arm rest 200 can rotate about the axis of the connection arm rest 100 when the side arm rest 200 is unlocked from the connection arm rest 100.

It should be noted that the side arm rest assembly 1000 is suitable for use in a passenger vehicle, and the side arm rest assembly 1000 may be installed in a wheelchair region of the passenger vehicle, and generally rotates the side arm rest 200 from the deployed position to the stowed position (the position shown in fig. 35) when the passenger in the wheelchair region does not need to use the side arm rest 200, and rotates the side arm rest assembly 1000 from the stowed position to the deployed position (the position shown in fig. 36) when the passenger is in the wheelchair region and the side arm rest 200 needs to be held or secured by the side arm rest 200. In this way, by rotating the side arm rest 200 with respect to the connecting arm rest 100, the use requirement of the side arm rest 200 for the passenger can be satisfied, and when the side arm rest 200 is not used, the side arm rest is in the storage position, and the passenger space in the vehicle is not excessively occupied.

The locking mechanism 300 is used to lock the side arm rest 200 and the connecting arm rest 100, that is, the locking mechanism 300 can lock the side arm rest 200 and the connecting arm rest 100 at the storage position or the expansion position so as to keep the relative positions of the side arm rest 200 and the connecting arm rest 100 stable, so that the side arm rest 200 does not rotate relative to the connecting arm rest 100 due to vibration of the vehicle 1001 and unintentional contact of passengers. The side handrail 200 can not disturb the passenger when stably keeping at the storage position, can provide reliable and effective supporting force and supporting force for the passenger when at the unfolding position, and ensures the safety of the passenger when taking a bus, and is convenient to use. The locking mechanism 300 may lock the side rail 200 and the connecting rail 100 through a pin and hole fit, or may lock the side rail 200 and the connecting rail 100 in a radial direction or in an axial direction.

The locking mechanism 300 is mounted to the side rail 200, wherein the locking mechanism 300 is disposed along the axial direction of the side rail 200, as shown in fig. 3, 18-20, a locking end of the locking mechanism 300 is diametrically opposite to the connecting rail 100, a locking end of the locking mechanism 300 axially extends to lock the side rail 200 and the connecting rail 100 along the radial direction of the connecting rail 100, and a locking end of the locking mechanism 300 axially contracts to unlock the side rail 200 and the connecting rail 100, thereby facilitating unlocking or locking of the side rail 200 and the connecting rail 100. In the specific locking and unlocking process, only the locking end of the locking mechanism 300 needs to be driven to move along the radial direction of the connecting handrail 100, the operation process is simple, and the situation that the locking is invalid or cannot be locked is not easy to occur. As shown in fig. 1, the side rail 200 further includes a mounting cover 530 for closing the locking groove 116 to stably mount the locking mechanism 300 to the first rotary joint 210.

As shown in fig. 35, 36, 41 and 42, the driving mechanism 400 is mounted on the side armrest 200, the driving mechanism 400 is connected to the locking mechanism 300, and an output end of the driving mechanism 400 can be directly connected to the locking mechanism 300, so that the driving force output by the driving mechanism 400 can drive the locking mechanism 300 to act, so as to unlock the side armrest 200 and the connection armrest 100, which is beneficial to reducing power loss from the driving mechanism 400 to the locking mechanism 300, improving work efficiency of the driving mechanism 400, ensuring that the driving force output by the driving mechanism 400 can effectively and reliably drive the locking mechanism 300 to act, and improving accuracy and practicability of the side armrest assembly 1000.

Of course, the driving mechanism 400 and the locking mechanism 300 may also be connected through a transmission mechanism, for example, the output end of the driving mechanism 400 is connected with the input end of the locking mechanism 300 through a cable 416 (or a steel wire rope) to drive the locking mechanism 300 to act, so that the driving force output by the driving mechanism 400 can be transmitted in different directions, and thus, the installation positions of the driving mechanism 400 and the locking mechanism 300 are less limited by space, and can be flexibly set according to the actual requirement on space, thereby facilitating the installation and layout of the side guard handrail assembly 1000.

Thus, when the side armrest 200 needs to be rotated, the driving mechanism 400 drives the locking mechanism 300 to move along the radial direction of the connecting armrest 100, so as to unlock the side armrest 200 and the connecting armrest 100, that is, the side armrest 200 can rotate relative to the connecting armrest 100, and a passenger can rotate the side armrest 200 relative to the connecting armrest 100 to a storage position or a deployed position, so as to meet the use requirement of the side armrest 200 for the passenger. When the drive mechanism 400 is removed from the drive when the side rail 200 is rotated to the target position, the lock mechanism 300 is not controlled by the drive mechanism 400, and the lock mechanism 300 again holds the side rail 200 at the target position.

From this, link to each other with locking mechanical system 300 through actuating mechanism 400, can realize the side handrail 200 and be connected the automatic locking of handrail 100 and manual unblock, the passenger operates the degree of difficulty and hangs down, and convenient to use is convenient for the passenger and will incline handrail 200 and rotate to different positions, satisfies the user demand.

And the installation cost is lower without independently arranging driving equipment.

According to the side guard rail assembly 1000 of the embodiment of the application, at least part of the driving mechanism 400 extends out of the side rail 200, the locking mechanism 300 can be controlled by the manual driving mechanism 400 to act along the radial direction of the connecting rail 100, so that when a passenger needs to rotate the side rail 200, the side rail 200 and the connecting rail 100 are manually unlocked, and when the side rail 200 does not need to be rotated, the side rail 200 and the connecting rail 100 are automatically locked, so that the passenger has small operation difficulty and is convenient to use.
