A first aspect of the present invention provides a bump guard 110 that may be applied to a cargo bed 120 of a transportation device such as an elevator 100, truck, or the like.

The following takes the application of the above-mentioned collision avoidance apparatus 110 to the elevator 100 as an example, and the above-mentioned collision avoidance apparatus 110 will be described in detail with reference to the accompanying drawings.

As shown in fig. 1, 8 and 9, the elevator 100 includes a cargo compartment 120 and a collision prevention device 110, and the collision prevention device 110 is mounted on the cargo compartment 120 and is used to prevent cargo from colliding with a wall of the cargo compartment 120 after entering the cargo compartment 120.

Referring to fig. 1 and 8 to 10, the anti-collision device 110 includes a controller 114, a detection component 111, an alarm 113, and a blocking component 112, wherein the detection component 111, the alarm 113, and the blocking component 112 are all in communication connection with the controller 114, so as to realize signal interaction between the detection component 111 and the alarm 113 and the blocking component 112.

It should be noted that the controller 114 may be a separately provided controller 114, and the controller 114 is in communication connection with the control system of the elevator 100 to implement operation signal interaction between the control system of the elevator 100 and the controller 114; the control module having the functions of the controller 114 described above can also be integrated directly in the control system of the elevator 100.

The detection component 111 is installed in the cargo compartment 120, and the detection component 111 is used to form a distance detection area 1111 covering the wall of the cargo compartment 120 and at least a part of the inner space of the cargo compartment 120, and it can be understood that the distance detection area 1111 can completely cover the wall surface of the cargo compartment 120 or partially cover the wall surface of the cargo compartment 120.

The blocking end of the blocking member 112 is disposed in the distance detection region 1111, and the blocking member 112 is used for opening or closing the blocking end according to the detection signal of the detection member 111, which is understood to mean a part of the structure of the blocking member 112 for blocking the cargo.

Specifically, the alarm 113 includes at least one of an audible alarm 113 and an optical alarm 113, such as a buzzer, a speaker, a warning light, an audible and visual alarm 113, and the like.

It should be noted that the wall may be one of the door wall 122, the rear wall 121 and the side wall 123 of the cargo compartment 120, and the detection component 111 may form the distance detection area 1111 on at least one wall of the cargo compartment 120.

When the detection component 111 detects that the cargo enters the distance detection area 1111, the controller 114 controls the alarm 113 to start to remind the operator to adjust the position of the cargo, if the operator does not adjust the position of the cargo in time, the cargo continues to move toward the wall, and when the detection component 111 detects that the cargo reaches a critical position (i.e. any position between the wall and a detection boundary line of the detection component 111 farthest from the wall, such as a middle boundary line between the wall and a detection point of the detection component 111 farthest from the wall, hereinafter referred to as a critical position) located in the distance detection area 1111, the controller 114 controls the blocking component 112 to start, so that the blocking end of the blocking component 112 is opened to block the cargo from continuing to move toward the wall. Therefore, the anti-collision device 110 has both an anti-collision early warning function and an active blocking function, and can effectively prevent the goods from colliding with the wall of the cargo compartment 120, thereby reducing the maintenance cost of the elevator 100.

In one embodiment, as shown in fig. 1, the detecting assembly 111 includes at least two light curtain sensors 1112, and each light curtain sensor 1112 is sequentially disposed along a direction away from the car wall.

Specifically, the light curtain sensor 1112 includes a light emitter and a light receiver, the light emitter is disposed on one side of the car wall, the light receiver is disposed on the other side of the car wall, the light emitter emits detection light toward the light receiver, when a cargo is present between the light emitter and the light receiver, the cargo will at least partially block the detection light, so that the light receiver cannot receive the partial detection light, thereby triggering the light curtain sensor 1112 to send a detection signal to the controller 114.

Taking the example where the detection assembly 111 includes two light curtain sensors 1112, when the cargo enters the detection area of the light curtain sensor 1112 farthest from the car wall (i.e. the area between the light emitter and the light receiver of the light curtain sensor 1112), the controller 114 controls the alarm 113 to activate to remind the staff member to adjust the position of the cargo. If the worker does not adjust the position of the cargo in time, so that the cargo continues to move toward the wall until entering the detection area of the light curtain sensor 1112 closest to the wall (i.e., the above-mentioned critical position), the controller 114 controls the blocking assembly 112 to be activated, so that the blocking end of the blocking assembly 112 is opened to block the cargo from continuing to move toward the wall.

By adopting the technical scheme, the anti-collision early warning function and the active blocking function of the anti-collision device 110 can be effectively realized, and the collision between goods and the wall of the cargo compartment 120 can be effectively prevented, so that the maintenance cost of the elevator 100 is reduced.

In another embodiment, as shown in fig. 2, the detecting component 111 includes a range radar 1113, and a detecting end of the range radar 1113 is disposed away from the car wall.

When the goods enter the detection range of the ranging radar 1113, the controller 114 controls the alarm 113 to start so as to remind the staff to adjust the position of the goods. If the worker does not adjust the position of the cargo in time, so that the cargo continues to move toward the wall, until the ranging radar 1113 detects that the cargo reaches the critical position, the controller 114 controls the blocking assembly 112 to start, so that the blocking end of the blocking assembly 112 is opened to block the cargo from continuing to move toward the wall.

By adopting the technical scheme, the anti-collision early warning function and the active blocking function of the anti-collision device 110 can be effectively realized, and the collision between goods and the wall of the cargo compartment 120 can be effectively prevented, so that the maintenance cost of the elevator 100 is reduced.

In one embodiment, as shown in fig. 8 and 9, the blocking assembly 112 includes a driver 1121 and a blocking member 1122 serving as the blocking end, and the driver 1121 is communicatively connected to the controller 114. Before the cargo reaches the critical position, the blocking member 1122 is in a closed state, and when the cargo reaches the critical position, the controller 114 controls the driver 1121 to drive the blocking member 1122 to open, so that the cargo can be effectively blocked from moving toward the wall, and the cargo is prevented from colliding with the wall.

Specifically, a concave cavity is formed on the carriage bottom 124, when the blocking member 1122 is in the closed state, the blocking member 1122 is placed in the concave cavity, and the surface of the blocking member 1122 is flush with the surface of the carriage bottom 124, so that the flatness of the surface of the carriage bottom 124 is ensured. The driver 1121 may be installed at any position of the cargo box 120, and optionally, in order to shorten the driving distance of the driver 1121, the driver 1121 is installed at the bottom of the box bottom 124.

In one specific example of the present embodiment, please refer to fig. 8, the blocking member 1122 is telescopically mounted on the bottom 124 of the cargo compartment 120, that is, the blocking member 1122 can perform a telescopic motion on the bottom 124 along the direction of the arrow shown in fig. 8. When the cargo reaches the threshold position, the controller 114 controls the driver 1121 to drive the blocking member 1122 from the cavity to extend toward the cargo space of the cargo box, so as to block the cargo from continuing toward the compartment wall, thereby preventing the cargo from colliding with the compartment wall.

Specifically, in order to improve the movement stability of the blocking member 1122, a sliding guide structure is disposed between the outer wall of the blocking member 1122 and the inner wall of the cavity, for example, a sliding rail (not shown) is disposed on the inner wall of the cavity, the sliding rail extends in the direction of the arrow in fig. 8, and a sliding block (not shown) is disposed on the outer wall of the blocking member 1122, and the sliding block is in sliding fit with the sliding rail; for another example, a sliding rail (not shown) is disposed on an outer wall of the blocking member 1122, the sliding rail extends along the direction of the arrow in fig. 8, and a sliding block (not shown) is disposed on an inner wall of the cavity, and the sliding block is slidably engaged with the sliding rail.

In another embodiment of this embodiment, please refer to fig. 9, the blocking member 1122 can be installed on the bottom 124 of the cargo compartment 120 in a reversible manner, i.e., the blocking member 1122 can perform a reversible movement on the bottom 124 along the direction of the arrow shown in fig. 9. When the cargo reaches the critical position, the controller 114 controls the driver 1121 to drive the blocking member 1122 to turn from the cavity to the cargo space of the cargo box, so as to block the cargo from continuing to the direction of the compartment wall, thereby preventing the cargo from colliding with the compartment wall.

It should be noted that the kind of the driver 1121 includes various kinds, such as a motor, an electric pneumatic cylinder, an electric hydraulic cylinder, etc., and is not limited herein.

In one embodiment, the collision avoidance device 110 further includes a viewing mirror (not shown), which may be a convex mirror or a flat mirror, mounted within the cargo compartment 120, e.g., mounted on a wall of the compartment; for another example, the observation mirror is mounted on the roof of the car; for another example, the observation mirror is installed at a top corner of the cargo box 120.

Through installing the sight glass in the goods railway carriage or compartment 120, the staff accessible sight glass observes the distance between the goods and a certain or more walls of goods railway carriage or compartment 120, can avoid goods and walls to bump more effectively, and the mode through staff's initiative observation goods position can effectively reduce the number of times that triggers of determine module 111, thereby reduce attention device 113 and block subassembly 112's the number of times that starts, and then can effectively reduce buffer stop 110's operation energy consumption, can effectively prolong buffer stop 110's life simultaneously.

In one embodiment, the bump guard 110 further includes a shield (not shown) disposed on the wall of the compartment. Specifically, the protection member is a protection plate or a protection pad, the protection member covers the wall surface of the compartment wall to partially or completely cover the compartment wall, and when the blocking assembly 112 cannot block the cargo (for example, the cargo collapses), the cargo contacts the protection member, so that the cargo is prevented from directly contacting the compartment wall, and the protection effect on the compartment wall can be effectively achieved.

In one embodiment, please refer to fig. 10, the collision avoidance apparatus 110 further includes a memory 115, and the memory 115 is communicatively connected to the controller 114 to enable data interaction between the memory 115 and the detection component 111. The memory 115 is used for storing collision data generated during the use of the elevator 100, and a manager reads the collision data periodically or aperiodically and analyzes the collision data, and then trains workers according to the analysis result and completes loading operation specifications, so that the management level is improved, and collision accidents are avoided.

A second aspect of the utility model provides an elevator 100 comprising a cargo compartment 120 and a bump guard 110 of any one or more of the embodiments described above, the bump guard 110 being mounted on the cargo compartment 120.

The elevator 100 is generally divided into a single-door elevator and a double-door elevator, and a case where the above-described guard is applied to the single-door elevator will be described in detail below.

In one embodiment, as shown in fig. 1 and 2, the wall of the cargo compartment 120 includes a door wall 122 and a rear wall 121 disposed opposite to the door wall 122, and the detection component 111 of the crash barrier 110 forms a distance detection area 1111 at a side of the rear wall 121 close to the door wall 122. It is understood that the door wall 122 refers to a wall of the cargo compartment 120 for mounting a door.

Since the rear wall 121 is located at a position opposite to the door wall 122, when the cargo enters the cargo compartment 120, the cargo moves from the door wall 122 to the rear wall 121, the rear wall 121 is located at a side of the cargo facing away from the worker, and the cargo blocks the sight of the worker, so that the probability of collision between the cargo and the rear wall 121 is high. By forming the distance detection area 1111 on the rear wall 121, the collision between the goods and the rear wall 121 can be effectively avoided, so that the number of the detection assemblies 111 can be reduced, the production cost of the anti-collision device 110 can be reduced, the protection effect on the goods compartment 120 can be effectively achieved, and the maintenance cost of the elevator 100 can be reduced.
