Abstract
Description
Technical Field
[0001] This application relates to the field of road warning sign technology, and in particular to a triangular warning sign device and a warning sign delivery equipment. Background Technology
[0002] A warning triangle is a warning sign placed behind a vehicle when it encounters a sudden breakdown requiring repair or an accident. It is highly visible on the road to remind other passing vehicles to give way and avoid secondary accidents.
[0003] For ease of storage, existing warning triangles are typically disassembled and / or foldable. When needed, they require manual removal from the vehicle for assembly and / or unfolding before placement. With the development of artificial intelligence, many driverless vehicles (logistics vehicles, garbage trucks, etc.) have appeared on the road. However, existing warning triangles require manual operation and cannot be used with driverless vehicles. Using fixed-form warning triangles would take up a significant amount of space in driverless vehicles. Utility Model Content
[0004] The main objective of this application is to provide a triangular warning sign device that aims to improve the problem that existing warning signs require manual operation for assembly and / or deployment.
[0005] To achieve the above objectives, this application proposes a triangular warning sign device, which includes a mounting base, a warning sign, a switch, and connecting components; wherein,
[0006] One side of the warning sign is rotatably mounted to the mounting base via the connecting assembly, and has a first position for warning and a second position for storage relative to the mounting base.
[0007] The switch is mounted on the mounting base and is used to lock the warning sign in the second position. The unlocking operation part of the switch is exposed on the side of the mounting base away from the warning sign. When the triangular warning sign device touches the ground, the unlocking operation part contacts the ground to unlock the warning sign.
[0008] The connecting component is also elastic, so that when the switch unlocks the warning sign, it elastically drives the warning sign to switch from the second position to the first position.
[0009] In some embodiments of this application, the connecting component is a hydraulic door closing hinge.
[0010] In some embodiments of this application, the connecting assembly includes a pivot and a torsion spring. One side of the warning sign is rotatably mounted to the mounting base via the pivot. The torsion spring is mounted on the pivot, and the two spring arms of the torsion spring elastically abut against the warning sign and the mounting base, respectively.
[0011] In some embodiments of this application, the mounting base includes a mounting plate having mounting surfaces and bearing surfaces facing each other, and the mounting plate is also provided with a through hole. One side of the warning sign is rotatably mounted on the mounting surface via the connecting assembly, the switch is mounted on the mounting surface, and the unlocking operation part is exposed on the bearing surface through the through hole.
[0012] In some embodiments of this application, the mounting base further includes an anti-slip pad, which is fixedly installed on the bearing surface.
[0013] In some embodiments of this application, the switch includes a first spring plunger, a locking pin, and a fixing rope. One end of the fixing rope is fixedly connected to the side of the warning sign away from the connecting assembly. The locking pin is fixedly connected to the movable post of the first spring plunger and presses the other end of the fixing rope against the mounting surface under the elastic force of the first spring plunger to lock the warning sign in a second position. The locking pin also passes through the through hole, and the unlocking operation part is provided on the side of the locking pin away from the movable post.
[0014] This application also proposes a warning sign dispensing device for use in vehicles. The warning sign dispensing device includes a triangular warning sign device as described in any of the above claims and a dispensing device. The dispensing device includes a device housing and a locking component. The locking component is installed on the device housing and is used to lock the triangular warning sign device to the device housing. Under the control of the vehicle's control system, the triangular warning sign device is unlocked, causing the triangular warning sign device to fall to the ground under the action of gravity.
[0015] In some embodiments of this application, the mounting base is provided with a mating part, and the locking component includes an electronic lock. The electronic lock engages with the mating part to lock the triangular warning sign device to the device housing. The electronic lock is also electrically connected to the control system to unlock the mating part under the control of the control system.
[0016] In some embodiments of this application, the mounting base is provided with two mating parts and located on one side of the mounting base, and the locking assembly includes two electronic locks, with each of the two electronic locks corresponding to one of the two mating parts;
[0017] The device housing is also rotatably provided with a frame, the frame is provided with a receiving groove, the frame is also located on the side of the device housing away from the two electronic locks, and the other side of the mounting base is inserted into the receiving groove.
[0018] In some embodiments of this application, the device housing is further provided with a plurality of second spring plungers at intervals, and the plurality of second spring plungers elastically abut against the mounting base when the triangular warning sign device is locked to the device housing.
[0019] The triangular warning sign device provided in this application embodiment, through the above-described structural design, allows the warning sign to be locked in the second position using a switch when stored, reducing its space occupation. When in use, the warning sign can be placed directly on the ground. The unlocking mechanism contacts the ground under the weight of the warning sign itself, triggering the switch to unlock the sign. The warning sign then switches from the second position to the first position under the elastic drive of the connecting component, serving as a warning. Compared to existing technologies, the triangular warning sign device provided by this solution is not only easy to store but also requires no manual assembly and / or unfolding. It can be used directly on the ground to provide a warning without any further operation. Therefore, it can be applied to vehicle warning sign dispensing devices, allowing the dispensing device to place the warning sign on the ground for use, and can also be adapted to autonomous vehicles. Furthermore, the triangular warning sign device can also be placed directly on ordinary vehicles for the driver to remove and place on the ground, avoiding the problem of some drivers being unable to assemble and / or unfold the warning sign device promptly due to initial use.

Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0031] Furthermore, the use of terms such as "first" and "second" in this application is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. If the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed in this application.
[0032] This application provides a triangular warning sign device 100, which can be applied to a warning sign dispensing device 1000 on a vehicle. The vehicle can be an unmanned vehicle, such as an unmanned logistics vehicle or an unmanned garbage truck, or a regular vehicle, such as a passenger car or a bus. The triangular warning sign device 100 can also be directly placed in the vehicle for the driver's direct use. Please refer to the references. Figures 3 to 5 The triangular warning sign device 100 includes a mounting base 10, a warning sign 20, a switch 30, and a connecting component 40.
[0033] One side of the warning sign 20 is rotatably mounted to the mounting base 10 via a connecting assembly 40, and has a first position for warning and a second position for storage relative to the mounting base 10. The warning sign 20 can be a traditional triangular warning sign 20, or other derived triangular warning sign 20 forms, such as a tetrahedral triangular warning sign 20. The warning sign 20 typically also includes reflective strips or other reflective elements. Understandably, when the warning sign 20 is in the first position for warning, it typically forms an angle of 70° to 90° with the mounting base 10. When the warning sign 20 is in the second position for storage, it is typically parallel or nearly parallel to the mounting base 10 to reduce the space occupied by the triangular warning sign 20 and facilitate storage.
[0034] The switch 30 is mounted on the mounting base 10 and is used to lock the warning sign 20 in the second position. The unlocking operation part 321 of the switch 30 is exposed on the side of the mounting base 10 away from the warning sign 20. When the triangular warning sign device 100 touches the ground, the unlocking operation part 321 contacts the ground to unlock the warning sign 20.
[0035] There are various types of switches 30. One type is a one-time locking mechanism, where the unlocking operation part is a breakable section of the locking mechanism. When the triangular warning sign device 100 contacts the ground, the device's own weight causes the unlocking operation part 321 to contact the ground, meaning the breakable part of the locking mechanism collides with the ground, causing the locking mechanism to break and thus unlocking the warning sign 20. Another type is a resilient push-button switch, where the unlocking operation part 321 is a button. When the triangular warning sign device 100 contacts the ground, the unlocking operation part 321 contacts the ground, meaning the button contacts the ground under its own weight, squeezing the button unlocks the switch and thus unlocks the warning sign 20. Specific types of switches 30 will not be listed here.
[0036] The connecting component 40 is also flexible, so that when the switch 30 unlocks the warning sign 20, the flexible drive of the warning sign 20 switches from the second position to the first position. This connecting component 40 can be a hydraulic door closer hinge, a common type of door closer available in various specifications, which can be directly purchased on the market to reduce the production cycle of the triangular warning sign 20. Furthermore, the rebound force of the hydraulic door closer hinge can usually be adjusted according to actual needs. Hydraulic door closer hinges are common components and will not be described in detail. This connecting component 40 can also be other types of door closer hinges.
[0037] In some examples, the connecting component 40 may also include a common hinge and a torsion spring. The hinge rotates the warning sign 20 to the mounting base 10, and the torsion spring is elastically installed between the warning sign 20 and the mounting base 10. The torsion spring elastically drives the warning sign 20 to switch from the second position to the first position. Compared with the above-mentioned solution where the connecting component 40 is a hydraulic door closing hinge, this solution has a lower cost for the purchased components.
[0038] Understandably, in the aforementioned schemes where the connecting component 40 is a hydraulic door hinge or includes a conventional hinge, the warning sign 20 typically requires two or more hinges to be rotatably mounted on the mounting base 10. In some other examples, the connecting component 40 may also include a pivot and a torsion spring. One side of the warning sign 20 is rotatably mounted on the mounting base 10 via the pivot, and the torsion spring is mounted on the pivot. The two arms of the torsion spring elastically abut against the warning sign 20 and the mounting base 10, respectively. With this configuration, compared to the aforementioned scheme where the warning sign 20 is rotatably mounted on the mounting base 10 via hinges, this scheme is easier to install and facilitates the assembly of the triangular warning sign device 100.
[0039] The triangular warning sign device 100 provided in this application embodiment, through the above-described structural configuration, allows the warning sign 20 to be locked in the second position using the switch 30 when stored, reducing the space occupied by the warning sign 20. When using the warning sign 20, it can be placed directly on the ground. The unlocking operation unit 321 contacts the ground under the weight of the warning sign device 100 itself, triggering the switch 30 to unlock the warning sign 20. Then, the warning sign 20 can be switched from the second position to the first position under the elastic drive of the connecting component 40 to serve as a warning. Compared with the prior art, the triangular warning sign device 100 provided by this technical solution is not only easy to store, but also requires no manual assembly and / or unfolding. It can be used directly on the ground to serve as a warning without any other operations. In this way, it can be applied to the warning sign dispensing device 1000 for vehicles, allowing the dispensing device 200 of the warning sign dispensing device 1000 to be placed on the ground for use, and can also be adapted to autonomous vehicles. In addition, the triangular warning sign device 100 can also be placed directly on ordinary vehicles for drivers to take out and place on the ground for use, avoiding the problem that some drivers cannot assemble and / or unfold the triangular warning sign device 100 in time due to first-time use.
[0040] In some examples, such as Figures 2 to 5 As shown, the mounting base 10 includes a mounting plate 11, which has mounting surfaces 111 and a bearing surface facing each other. The mounting plate 11 also has a through hole. One side of the warning sign 20 is rotatably mounted on the mounting surface 111 via a connecting assembly 40. The switch 30 is mounted on the mounting surface 111, and the unlocking operation part 321 is exposed on the bearing surface through the hole. With this configuration, when the warning sign 20 is placed on the ground, it can be supported by the bearing surface. Since the switch 30 is mounted on the mounting surface 111, and only the unlocking operation part 321 is exposed on the bearing surface through the hole, interference from the ground to other parts of the switch 30 and the connecting assembly 40 is reduced when the warning sign 20 is placed on the ground.
[0041] In some examples, such as Figure 2 As shown, the mounting base 10 also includes an anti-slip pad 12, which is fixedly installed on the bearing surface. The anti-slip pad 12 can be made of rubber, silicone, etc., and can be fixedly installed on the bearing surface by adhesive. The anti-slip pad 12 is designed to increase the static friction between the warning triangle 20 and the ground, and to prevent the warning triangle 20 from moving under the action of external forces.
[0042] It should be emphasized that in some examples, the anti-slip pad 12 can cover the entire bearing surface of the mounting base 10, while in other examples, the anti-slip pad 12 may not cover the entire bearing surface of the mounting base 10, and the anti-slip pad 12 may have an anti-slip pattern on the side facing away from the bearing surface.
[0043] In some examples, such as Figures 2 to 5 As shown, the switch 30 includes a first spring plunger 31, a locking pin 32, and a fixing rope 33. One end of the fixing rope 33 is fixedly connected to the side of the warning sign 20 away from the connecting assembly 40. The locking pin 32 is fixedly connected to the movable post of the first spring plunger 31 and presses the other end of the fixing rope 33 against the mounting surface 111 under the elastic force of the first spring plunger 31 to lock the warning sign 20 in the second position. The locking pin 32 also passes through a through hole, and an unlocking operation part 321 is provided on the side of the locking pin 32 away from the movable post.
[0044] The first spring plunger 31 is a common type of spring plunger available on the market, with numerous specifications, and can be directly purchased to reduce the production cycle of the warning triangle 20. It should be emphasized that the movable pin of the first spring plunger 31 is movable along its length, and a spring is installed inside the first spring plunger 31. The spring plunger itself is a common component and will not be described in detail. The fixing rope 33 can be a nylon rope, steel wire, etc.
[0045] With this configuration, when the triangular warning sign device 100 is placed on the ground, the unlocking operation part 321 of the locking pin 32 contacts the ground, and the locking pin 32 is subjected to a reaction force that squeezes the movable column back, thus releasing the fixing rope 33. The switch 30 then unlocks the warning sign 20, and the warning sign 20 can be quickly switched from the second position to the first position under the elastic drive of the connecting component 40. In this way, the switch 30 can not only be reused, but also has high reliability.
[0046] Please refer to the reference. Figures 1 to 5 This application also proposes a warning sign dispensing device 1000 for use in vehicles. The warning sign dispensing device 1000 includes a dispensing device 200 and a triangular warning sign device 100. The specific structure of the triangular warning sign device 100 is as described in the above embodiments. Since this warning sign dispensing device 1000 adopts all the technical solutions of all the above embodiments, it possesses at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be elaborated further here. The dispensing device 200 includes a device housing 210 and a locking component 220. The locking component 220 is installed in the device housing 210 and is used to lock the triangular warning sign device 100 to the device housing 210. Under the control of the vehicle's control system, the triangular warning sign device 100 is unlocked, allowing it to fall to the ground under gravity. The dispensing device 200 may also include a robotic arm, grippers, or other structures.
[0047] The warning sign delivery device 1000 provided in this application embodiment, through the above-described structural configuration, when the triangular warning sign device 100 needs to be used, uses the vehicle's control system to control the locking component 220 to unlock the triangular warning sign device 100. After the triangular warning sign device 100 is no longer constrained by the locking component 220, it will detach from the device housing 210 under the action of gravity and fall to the ground, where it can be used.
[0048] It needs to be emphasized again that the above-mentioned vehicles can be driverless vehicles with an artificial intelligence control system, or they can be ordinary vehicles that require a driver to control the vehicle's control system.
[0049] The following describes the application of the warning sign deployment device 1000 to an autonomous vehicle: When the autonomous vehicle's control system (autonomous driving system) detects an anomaly, i.e., the artificial intelligence control system detects a vehicle malfunction, the control system will instruct the autonomous vehicle to pull over to the side of the road to await assistance. During this process, the autonomous vehicle gradually reduces its speed and moves closer to the side of the road. Once the autonomous vehicle has slowed to a certain speed, the control system activates the locking component 220 to unlock the warning sign device 100. Without the constraint of the locking component 220, the device will detach from the housing 210 under the action of gravity and fall to the ground, where it can be used. The deployment principle of the triangular warning sign device 100 can be referred to the above description of the specific structure of the triangular warning sign device 100. While the control system controls the locking component 220 to unlock the triangular warning sign device 100, the control system will continue to control the autonomous vehicle to drive. After the autonomous vehicle has traveled a certain distance, it will stop and wait for rescue. In this way, the triangular warning sign device 100 can be placed behind the autonomous vehicle to serve as a warning.
[0050] In some examples, such as Figures 1 to 3 As shown, the mounting base 10 is provided with a mating part 13, and the locking assembly 220 includes an electronic lock. The electronic lock engages with the mating part 13 to lock the triangular warning sign device 100 to the device housing 210. The electronic lock is also electrically connected to the control system to unlock the mating part 13 under the control of the control system. In some specific configurations, the electronic lock can be an electromagnetic lock, operating on low voltage (e.g., 12V). The mating part 13 is a latch. When the power is off, the electromagnetic lock engages with the latch to securely lock the triangular warning sign device 100. When the power is on, the electromagnetic lock releases the latch. In still other specific configurations, the electronic lock can use magnetic force to directly attract the mating part 13 to engage with it, securing the triangular warning sign device 100.
[0051] This design facilitates the electrical connection between the electronic lock and the vehicle's control system, and the electronic lock has a sensitive response speed, enabling it to quickly deploy the warning sign 20 device.
[0052] In some examples, such as Figures 1 to 3 As shown, the mounting base 10 has two mating parts 13 located on one side of the mounting base 10. The locking assembly 220 includes two electronic locks, which are arranged one-to-one with the two mating parts 13. The device housing 210 is also rotatably provided with a frame 211, which has a receiving groove 212. The frame 211 is located on the side of the device housing 210 away from the two electronic locks. The other side of the mounting base 10 is inserted into the receiving groove 212.
[0053] It is understandable that when the electronic lock releases the warning sign 20 device, the warning sign 20 device will cause the frame 211 to rotate under the action of gravity and gradually detach from the receiving groove 212 on the frame 211. Thus, the side of the mounting base 10 that gradually detaches from the receiving groove 212 will contact the ground later than the other side.
[0054] This configuration is designed to allow the triangular warning sign device 100 to detach more smoothly from the delivery device 200 when the locking assembly 220 releases it. Furthermore, the switch 30 of the warning sign device 20 is typically located on the side of the mounting base 10 furthest from the mating part 13. Thus, when the triangular warning sign device 100 is delivered, the side of the mounting base 10 closest to the mating part 13 can contact the ground first, while the side furthest from the mating part 13 can contact the ground later. In other words, the side of the mounting base 10 closest to the switch 30 can contact the ground later, which facilitates the switching of the warning sign 20 from the second position to the first position.
[0055] In some embodiments, the frame 211 may rotate relative to the device housing 210 at an angle ranging from 0° to 40°, and preferably, the frame 211 may rotate relative to the device housing 210 at an angle of 30°.
[0056] In some examples, such as Figure 3 As shown, the device housing 210 is also provided with a plurality of second spring plungers 213 at intervals. When the triangular warning sign device 100 is locked to the device housing 210, the plurality of second spring plungers 213 elastically abut against the mounting base 10 respectively.
[0057] The second spring plunger 213 and the aforementioned first spring plunger 31 can be of the same type or different types. The arrangement of multiple second spring plungers 213 is intended to utilize the elasticity of the spring plungers to adapt to the gap between the delivery device 200 and the warning triangle device 100, making the warning triangle device 100 more stable when locked onto the delivery device 200. Simultaneously, when the warning triangle device 100 is delivered, the elasticity of the multiple second spring plungers 213 can accelerate the delivery of the warning triangle device 100.
[0058] The aforementioned frame 211 may also be provided with multiple second spring plungers 213 spaced apart. The mounting base 10 may also be provided with a mating block that mates with the second spring plungers 213.
[0059] This application also proposes an unmanned vehicle, which includes a warning sign dispensing device 1000 and a control system. The specific structure of the warning sign dispensing device 1000 is as described in the above embodiments. Since the warning sign dispensing device 1000 adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.
[0060] The above description is merely an optional embodiment of this application and does not limit the patent scope of this application. Any equivalent structural transformations made based on the inventive concept of this application and the contents of the specification and drawings of this application, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this application.
