Description

Technical Field

[0001] This utility model relates to the field of traffic warning equipment, and in particular to a robot component. Background Technology

[0002] A car warning triangle is a passive reflective material made of plastic. When a driver encounters a sudden breakdown and stops for repairs or is involved in an accident, the reflective properties of the warning triangle can alert other vehicles to avoid it and prevent secondary accidents.

[0003] There are existing intelligent warning signs that are installed at the rear of vehicles. In the event of an emergency, the driver can control the intelligent warning sign to be lowered from the rear of the vehicle to the ground, and the warning sign can be moved to a predetermined distance from the rear of the vehicle to provide early warning.

[0004] However, current smart warning signs cannot be stored away; the signs are triangular and placed inside the casing, resulting in a large overall size that occupies too much vehicle space. Summary of the Invention

The warning sign includes a first connecting rod, a second connecting rod, and a third connecting rod, which are sequentially hinged together. The third connecting rod can switch between an extended position (extending in the lateral direction) and a retracted position (contracting in the lateral direction).

[0009] In this technical solution, when a driver encounters a sudden breakdown and needs to stop for repairs or is involved in an accident on the road, the warning sign is adjusted from a parallel position to a vertical position, and the length of the third connecting rod is adjusted from a retracted position to an extended position. Then, the moving trolley is controlled to move from one side of the vehicle toward the rear of the vehicle until it reaches the designated location.

[0075] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. The same reference numerals in the drawings represent the same components. It should be noted that the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0076] Unless otherwise defined, the technical or scientific terms used herein shall have the ordinary meaning understood by one of ordinary skill in the art to which this invention pertains. The terms “first,” “second,” and similar terms used in this patent application specification and claims do not indicate any order, quantity, or importance, but are merely used to distinguish different components. Similarly, “an” or “a” and similar terms do not necessarily indicate a quantity limitation. Terms such as “comprising” or “including” mean that the element or object preceding the word encompasses the element or object listed following the word and its equivalents, without excluding other elements or objects. Terms such as “connected” or “linked” are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. Terms such as “upper,” “lower,” “left,” and “right” are used only to indicate relative positional relationships; these relative positional relationships may change accordingly when the absolute position of the described object changes.

[0077] According to this utility model, a robot component, such as Figures 1 to 9 As shown, it includes:

[0078] The mobile trolley 200 has a bearing surface 211. For example, the mobile trolley 200 includes a housing 210 and guide wheels located at the lower end of the housing 210. For another example, the guide wheels include two drive wheels 220 and one omnidirectional wheel 230. The two drive wheels 220 and the omnidirectional wheel 230 are arranged in a triangle. The two drive wheels 220 are located at the rear end and are driven by a power motor 240, respectively. The omnidirectional wheel 230 is located at the front end. The two drive wheels 220 achieve turning of the mobile trolley 200 by differential speed movement.

[0079] The warning sign 100 is pivotally connected to the bearing surface 211 and can switch between a vertical position perpendicular to the bearing surface 211 and a parallel position parallel to the bearing surface 211. The warning sign 100 includes a first connecting rod 110, a second connecting rod 120, and a third connecting rod 130, which are sequentially hinged. The third connecting rod 130 can switch between an extended position (extending in the lateral direction) and a retracted position (retracting in the lateral direction). For example, a flexible reflective cloth can be attached to the warning sign 100.

[0080] When a driver encounters a sudden breakdown and needs to stop for repairs or is involved in an accident on the road, the warning sign 100 is adjusted from a parallel position to a vertical position, and the length of the third connecting rod 130 is adjusted from a retracted position to an extended position. Then, the moving trolley 200 is controlled to move from one side of the vehicle toward the rear of the vehicle until it reaches the designated location. After the repairs or accident are resolved, the moving trolley 200 is controlled to move from the designated location toward the vehicle. Once it reaches the designated location, the length of the third connecting rod 130 is adjusted from an extended position to a retracted position, and the warning sign 100 is adjusted from a vertical position to a parallel position. This robot component can be folded and extended for easy storage, greatly reducing the space occupied by the robot component and improving its flexibility.

[0081] In one example of this utility model, the third connecting rod 130 includes: a first rod 131, a second rod 132, and an adjusting member 136.

[0082] The first rod 131 and the second rod 132 are located on the same plane or two parallel planes. The adjusting member 136 connects the first rod 131 and the second rod 132 and is configured to adjust the first rod 131 and the second rod 132 to move away from or closer to each other in order to achieve switching between the extended position and the retracted position.

[0083] In other words, the adjustment function of the adjusting member 136 can make the first rod 131 and the second rod 132 move away from or closer to each other, thereby realizing the switching movement of the third connecting rod 130 between the extended position and the retracted position, thus facilitating the adjustment of the space occupied by the warning sign 100 and greatly facilitating the carrying of the warning sign 100.

[0084] For example, the adjusting element 136 can be a drive motor 136A or a telescopic device.

[0085] In one example of this utility model, such as Figures 1 to 4As shown, a first rack 133 is formed on the first rod 131, and a second rack 134 is formed on the second rod 132. The adjusting component is a drive motor 136A, and the drive motor 136A is provided with a drive gear 135. The drive gear 135 meshes with the first rack 133 and the second rack 134 respectively. The drive motor 136A is configured to realize the movement of the first rack 133 and the second rack 134 towards or away from each other by rotating forward or backward.

[0086] When the warning sign 100 needs to be unfolded, the drive motor 136A rotates forward, causing the drive gear 135 to rotate synchronously, and driving the first rack 133 and the second rack 134 meshed with it to move in opposite directions, thereby moving the warning sign 100 from the retracted position to the unfolded position. When the warning sign 100 needs to be retracted, the drive motor 136A rotates in reverse, causing the drive gear 135 to rotate synchronously, and driving the first rack 133 and the second rack 134 meshed with it to move in opposite directions, thereby moving the warning sign 100 from the unfolded position to the retracted position. The retraction and unfolding of the warning sign 100 are achieved by the drive motor 136A driving the first rack 133 and the second rack 134. This structure is convenient to control and has high reliability.

[0087] In one example of this utility model, it also includes: a connecting slot 140.

[0088] It is covered and connected to the third connecting rod 130, and a first snap-fit ​​hole 141 and a second snap-fit ​​hole 142 are formed in the connecting slot 140. The first snap-fit ​​hole 141 is adapted to the first rod 131, and the second snap-fit ​​hole 142 is adapted to the second rod 132.

[0089] Specifically, the connecting slot 140 is pivotally connected to the bearing surface 211 via a connector. For example, the connector includes two connectors, which are spaced apart along the extension direction of the connecting slot 140. The first engaging hole 141 and the second engaging hole 142 are provided in the connecting slot 140 to facilitate the engaging of the first rod 131 and the second rod 132. For example, the drive motor 136A is provided at the middle position of the connecting slot 140, and the first engaging hole 141 and the second engaging hole 142 are arranged parallel to each other on both sides of the drive motor 136A. Moreover, the connecting slot 140 covering the third connecting rod 130 can also protect the adjusting member 136.

[0090] Preferably, both the first locking hole 141 and the second locking hole 142 are stepped structures, so that the first locking hole 141 can be adapted to the first connecting rod and the first rack 133 formed thereon, and the second locking hole 142 can be adapted to the second connecting rod and the second rack 134 formed thereon.

[0091] Preferably, limiting protrusions are provided on both the first rod 131 and the second rod 132, so that the first rod 131 can be prevented from slipping off the first locking hole 141 or the second locking hole 142 when it is in the extreme extended position or the extreme retracted position.

[0092] In one example of this utility model, such as Figures 5 to 7 As shown, the adjusting member 136 includes a first screw 1361 and a second screw 1362. The first member 131 has a first threaded hole 1311, and the first screw 1361 engages with the first threaded hole 1311. The second member 132 has a second threaded hole 1321, and the second screw 1362 engages with the second threaded hole 1321. The threads of the first threaded hole 1311 and the second threaded hole 1321 have opposite directions of rotation, and the threads of the first screw 1361 and the second screw 1362 also have opposite directions of rotation.

[0093] Specifically, the adjusting member 136 includes a first screw 1361 and a second screw 1362. A first threaded hole 1311 is formed at one end of the first member 131 near the second member 132. One end of the first screw 1361 engages with the first threaded hole 1311, and when the first screw 1361 rotates within the first threaded hole 1311, it can move relative to the first member 131. The engagement between the first screw 1361 and the first threaded hole 1311 is as follows: Figure 5 As shown; similarly, the second rod 132 has a second threaded hole 1321 at one end near the first rod 131, and one end of the second screw 1362 engages with the second threaded hole 1321. When the second screw 1362 rotates within the second threaded hole 1321, the second screw 1362 can move relative to the second rod 132. A schematic diagram of the engagement between the second screw 1362 and the second threaded hole 1321 is shown below. Figure 5 Similarly, but the second threaded hole 1321 has the opposite thread direction to the first threaded hole 1311, and the second screw 1362 has the opposite thread direction to the first screw 1361.

[0094] When the adjusting member 136 is rotated, it can drive the first screw 1361 and the second screw 1362 to rotate. During the rotation, they respectively cooperate with the first threaded hole 1311 and the second threaded hole 1321, so that the first screw 1361 moves axially relative to the first rod 131 and the second screw 1362 moves axially relative to the second rod 132, thereby causing the first rod 131 and the second rod 132 to move closer to each other or further away from each other.

[0095] In one example of this utility model, such as Figure 8As shown, in the first rod 131 and the adjusting member 136, one is provided with a first slide rail 1312 and the other is provided with a first sliding rod 1363, which moves along the first slide rail 1312; in the second rod 132 and the adjusting member, one is provided with a second slide rail 1322 and the other is provided with a second sliding rod 1364, which moves along the second slide rail 1322; the adjusting member 136 further includes a first limiting component and a second limiting component, the first limiting component being used to limit the relative movement of the first sliding rod 1363 and the first slide rail 1312, and the second limiting component being used to limit the relative movement of the second sliding rod 1364 and the second slide rail 1322;

[0096] The adjusting member 136 includes a first limiting component and a second limiting component, wherein the first limiting component is used to limit the relative movement between the first sliding rod 1363 and the first slide rail 1312, and the second limiting component is used to limit the relative movement between the second sliding rod 1364 and the second slide rail 1322.

[0097] In this robot assembly, the operator can adjust the distance between the first rod 131 and the second rod 132 by controlling the relative movement between the first sliding rod 1363 and the first slide rail 1312 and the relative movement between the second sliding rod 1364 and the second slide rail 1322, so that the warning sign 100 can switch between an extended position and a retracted position. When the distance between the first rod 131 and the second rod 132 is adjusted to the correct position, the first limiting component and the second limiting component can fix the two in that position.

[0098] In one example of this utility model, each first slide rail 1312 and each second slide rail 1322 are parallel to each other, and the first sliding rod 1363 and the second sliding rod 1364 are separate structures, and each first sliding rod 1363 and each second sliding rod 1364 are parallel to each other, so that the first rod 131 and the second rod 132 can be prevented from twisting relative to each other during the movement of the first sliding rod 1363 and the second sliding rod 1364.

[0099] In one example of this utility model, the first sliding rod 1363 is provided with a first protrusion 13631, and the first slide rail 1312 is provided with a plurality of first recesses 13122. The first protrusion 13631 is engaged with any of the first recesses 13122, and the first limiting component includes the first protrusion 13631 and the first recesses 13122; the second sliding rod 1364 is provided with a second protrusion 13641, and the second slide rail 1322 is provided with a plurality of second recesses 13222. The second protrusion 13641 is engaged with any of the second recesses 13222, and the second limiting component includes the second protrusion 13641 and the second recesses 13222.

[0100] Preferably, the first slide rail 1312 is provided with a first spring piece 13121 inside, and the first spring piece 13121 is bent to form the first recess 13122; the second slide rail 1322 is provided with a second spring piece 13221 inside, and the second spring piece 13221 is bent to form the second recess 13222.

[0101] Specifically, the first slide rail 1312 is provided with a first spring piece 13121 inside. The first spring piece 13121 is made of elastic material, and the first spring piece 13121 is bent to form a plurality of the aforementioned first recesses 13122. Similarly, the second slide rail 1322 is provided with a second spring piece 13221 inside. The second spring piece 13221 is made of elastic material, and the second spring piece 13221 is bent to form the aforementioned second recesses 13222. Specifically, the first spring piece 13121 can be stamped to form the aforementioned first recesses 13122, and the second spring piece 13221 can be stamped to form the second recesses 13222.

[0102] In the embodiments of this utility model, when each of the first recesses 13122 and the second recesses 13222 is formed by a spring sheet, the spring sheet can be elastically deformed when subjected to force. Taking the first spring sheet 13121 and the first protrusion 13631 as an example, when the first sliding rod 1363 slides in the first slide rail 1312, the first protrusion 13631 moves along the surface of the first spring sheet 13121 and applies pressure to the first spring sheet 13121. Under the action of this pressure, the first spring sheet 13121 elastically deforms, thereby enabling the first protrusion 13631 to move with the first sliding rod 1363.

[0103] Therefore, when the spring sheet is installed in the first slide rail 1312 and the second slide rail 1322, it can ensure that the sliding rod and the slide rail can move relative to each other, and can also limit their movement, and has the advantage of simple structure.

[0104] Furthermore, both the first protrusion 13631 and the second protrusion 13641 can be made of elastic material. When the sliding rod moves along the slide rail, both the protrusion and the spring can be elastically deformed, thereby reducing the resistance during the movement of the sliding rod and improving the reliability of the engagement between the protrusion and the recess.

[0105] The outer contours of the first protrusion 13631 and the second protrusion 13641 are both arc-shaped. Correspondingly, the outer contours of the first recess 13122 and the second recess 13222 are also arc-shaped, so that the protrusions and the spring sheet have a smooth transition, thereby further reducing the resistance during the relative movement of the sliding rod and the slide rail, and reducing the wear of the protrusions and the spring sheet, thus improving the service life.

[0106] In one example of this utility model, it further includes: a first telescopic member 150, which includes a first cylinder 152 and a first piston rod 151 that telescopically extends within the first cylinder 152. Of the first cylinder 152 and the first piston rod 151, one is hinged to a first connecting rod 110 and a second connecting rod 120, and the other is connected to a third connecting rod 130. The first telescopic member 150 is configured to telescopically adjust its movement synchronously with the third connecting rod 130 when the third connecting rod 130 switches between an extended position and a retracted position.

[0107] In other words, when the third connecting rod 130 extends and retracts, the height of the warning sign 100, which is the base of the triangle structure, also changes. The first telescopic component 150 is designed to adapt to the height change caused by the change in length of the third connecting rod 130 and to support the warning sign 100.

[0108] It should be noted that, in order to facilitate the extension and retraction adjustment of the warning sign 100, a first rotating member 160 is hinged to one end of the first rod 131, and the other end of the first rod 131 is hinged to the first connecting rod 110. A second rotating member 170 is hinged to one end of the second rod 132, and the other end of the second rod 132 is hinged to the second connecting rod 120.

[0109] In one example of this utility model, the third connecting rod 130 is a second telescopic member, which includes a second cylinder and a second piston rod that telescopically extends within the second cylinder. Of the second cylinder and the second piston rod, one is hinged to the first connecting rod 110, and the other is hinged to the second connecting rod 120.

[0110] In other words, the third connecting rod 130 is a telescopic component, and the telescopic movement of the second telescopic component enables the switching movement of the third connecting rod 130 between the extended position and the retracted position.

[0111] In one example of this utility model, the warning sign 100 is pivotally connected to the bearing surface 211 via a drive mechanism 180, and is capable of switching between a vertical position perpendicular to the bearing surface 211 and a parallel position parallel to the bearing surface 211. The drive mechanism 180 includes:

[0112] A rotary motor is fixedly mounted on the housing 210, and its output shaft is connected to the pivot shaft of the warning sign 100. It is configured to rotate the output shaft of the rotary motor to drive the warning sign 100 to switch between an open position perpendicular to the bearing surface 211 and a closed position parallel to the bearing surface 211.

[0113] For example, it also includes: a speed reducer, which is disposed between the output shaft and the pivot shaft, for reducing the speed of the motor;

[0114] For example, the output end of the reducer is connected to the pivot shaft of the warning sign 100 via a coupling.

[0115] Of course, this utility model is not limited to this. The drive mechanism 180 can also be a hinge, and the warning sign 100 can also be connected by a hinge and manually switch between vertical and parallel positions.

[0116] In one example of this utility model, it also includes: a controller 300.

[0117] It is coupled to the power motor 240 and configured to control the movement of the mobile trolley 200;
