Description

Technical Field

[0001] This utility model relates to the field of automotive safety auxiliary equipment technology, and in particular to a car fault warning device that can be quickly retracted and extended. Background Technology

[0002] Existing automotive fault warning devices have undergone some improvements in their technical solutions. For example, Chinese utility model patent CN206287920U, "A Three-Dimensional Folding Warning Tripod for Automobiles," discloses a technical solution including a tripod and a warning light: the tripod consists of legs, a gimbal mount, and a connecting assembly; reflective film is attached to the legs; the warning light is fixed to the gimbal mount with nuts, and the warning light includes an LED light source and an alarm horn, enabling folding storage and providing both audible and visual warnings. While this solution addresses the problems of traditional flat warning signs having a single warning direction and poor nighttime warning effect, it still has significant technical shortcomings. First, the deployment operation relies on manual adjustment of the outriggers and connecting assemblies, lacking an automatic deployment mechanism. Each outrigger must be adjusted individually, making the operation cumbersome and time-consuming. In dangerous scenarios such as highways, the safety risks for the driver during placement are high. Second, there is no center of gravity adjustment or counterweight structure. Stability is only improved by the anti-slip pads at the bottom of the outriggers. In environments with high-speed airflow (such as airflow generated by passing vehicles traveling at high speed) or uneven road surfaces (such as slopes or bumpy roads), it is prone to tipping over, and its wind resistance and anti-overturning ability are weak. Third, there is no lateral connection and stabilizing structure between the outriggers, and the rigidity of the overall support frame is insufficient. It is prone to deformation when subjected to external impact, and its stability is difficult to meet the requirements of complex road conditions.

[0003] In addition, traditional car warning signs have two typical problems: one is the interlocking structure, which is composed of three plastic plates that are manually interlocked. The placement process is time-consuming and the overall structure is loose after assembly, without any stabilizing or reinforcing design; the other is the early folding improved structure, which can be folded for storage, but requires multiple operations of the locking parts when unfolding, resulting in poor locking reliability. Furthermore, it has not been optimized for wind resistance and tipping resistance, and still cannot solve the core pain points of "slow placement and easy tipping".

[0004] The root cause of the shortcomings of the aforementioned existing technologies lies in the fact that their design focuses solely on "warning function implementation" (such as reflectivity and audible / visual effects), without optimizing for "ease of operation" and "stability in complex scenarios." This includes a lack of an automatically deployable mechanical structure, resulting in low operational efficiency; and the absence of adjustable counterweight components and lateral stabilization structures, leading to instability in high-speed, uneven, and other hazardous scenarios. Therefore, there is an urgent need for a vehicle malfunction warning sign solution that can achieve rapid deployment and retrieval, significantly enhance stability, and adapt to complex road conditions to address the deficiencies of existing technologies.

Figure 5 A schematic diagram of the structure viewed from below. Detailed Implementation

[0019] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] See Figures 1-6 This utility model discloses a quickly retractable car fault warning device, including a support assembly 1, a reflector assembly 2, and a warning light assembly 3; the support assembly 1 includes a fixing plate 14, a first support leg 11, a second support leg 12, and at least one third support leg 13; the reflector assembly 2 includes a first reflector 21, a second reflector 22, and a third reflector 23; The head of the second reflector 22, the head of the first support leg 11, the head of the third reflector 23, and the head of the second support leg 12 are sequentially attached to and hinged to the bottom surface of the fixed plate 14. The bottom of the second reflector 22 is fixed to the bottom of the first support leg 11, the bottom of the third reflector 23 is fixed to the bottom of the second support leg 12, and the bottom of the first reflector 21 is attached to and hinged to the bottom of the second reflector 22. The first reflector 21 has a groove 211 on its head facing the back of the second reflector 22, and the bottom surface of the third reflector 23 has a protrusion 231. The groove 211 is used to fit onto the protrusion 231 to fix the head of the first reflector 21; or, the first reflector 21 includes a first sub-reflector 21a and a second sub-reflector 21b. The first end of the first sub-reflector 21a is hinged to the bottom of the third reflector 23, and the second end is hinged to the first end of the second sub-reflector 21b. The second end of the second sub-reflector 21b is hinged to the bottom of the second reflector 22. The warning light assembly 3 is fixed on the fixing plate 14 and is used for emitting light to warn.

[0021] For example, a scenario of a vehicle suddenly breaking down on a highway (at night): 1. Fault Triggering and Device Removal: After discovering a fault in the vehicle's engine, the driver pulls the vehicle over to the emergency lane, turns on the hazard lights, and removes the warning device from the trunk.

[0022] 2. Rapid deployment: The driver holds the top of the fixed plate 14 with one hand and gently pulls the first support leg 11, the second support leg 12 and the third support leg 13 outward with the other hand: as the support legs rotate and unfold around the hinge point on the bottom surface of the fixed plate 14, they unfold synchronously with the second reflector 22 and the third reflector 23 fixed at the bottom of the support legs. See Figures 1-4 If it is a "groove 211-protrusion 231" structure: when the support leg is pulled, the bottom of the first reflector 21 rotates with the second reflector 22. After the support leg is extended to the preset triangular support angle, align the groove 211 at the head of the first reflector 21 with the protrusion 231 at the bottom of the third reflector 23, and press gently to complete the locking and fixing. The whole process does not require any additional tools. See Figures 5-6 If it is a "two-sub-reflector" structure: when the support leg is unfolded, the first sub-reflector 21a rotates with the third reflector 23 and the second sub-reflector 21b rotates with the second reflector 22. The two sub-reflectors naturally unfold around the hinge point to fit together, forming a complete reflective surface without the need for additional fixing steps.

[0023] 3. Warning activation and safe evacuation: After unfolding, turn on the warning light assembly 3 on the fixed plate 14. The warning light will flash, and the driver will immediately return to the vehicle and call for help. During this time, passing vehicles can identify the location of the disabled vehicle in advance through the reflector on the three-dimensional frame (reflecting the headlights at night) and the steadily flashing warning light, thus avoiding rear-end collisions.

[0024] 4. Device folding and storage: After the rescue is completed, the driver returns to the device: If it is a "groove 211-protrusion 231" structure, pry the head of the first reflector 21 outward to disengage from the protrusion 231. The support leg will fold towards the fixed plate 14 under its own weight and the hinge's reset tendency. The first reflector 21 will then adhere to the support leg along with the second reflector 22. If it is a "two-sub-reflector" structure, push the support leg inward directly. The two sub-reflectors will fold around the hinge point. Finally, the support leg and the reflectors will both adhere to the fixed plate 14. After folding, it can be placed in the trunk.

[0025] This utility model constructs a simple hinged motion structure by "the head of the reflector and the head of the support leg are sequentially hinged to the bottom surface of the fixed plate 14" and "the bottom of the reflector and the bottom of the support leg are fixed / hinged". The first reflector 21 is quickly locked by "the groove 211 with the protrusion 231" or by "the two reflectors are hinged" and unfolded / folded synchronously with the support leg. No additional locking parts are required throughout the process, and the driver can complete the operation by himself, which significantly shortens the deployment time. It is especially suitable for dangerous scenarios such as highways, reducing the time the driver is exposed to traffic and ensuring personal safety. The reflector and the support leg form a three-dimensional linkage frame with strong overall rigidity, which is not easy to tip over in high-speed airflow (such as the airflow of passing vehicles) or on uneven road surfaces. The warning light assembly 3 is fixed on the fixed plate 14 to prevent the warning light from shifting due to the shaking of the tripod and ensure stable transmission of the warning signal.

[0026] In an optional embodiment, a lighting assembly 4 is also included; a mounting position is provided at the center of the top surface of the fixing plate 14, and the warning light assembly 3 is fixed to the fixing plate 14 through the mounting position; The warning light assembly 3 is used to emit flashing light to indicate a fault, and the lighting assembly 4 is used to emit constant light to illuminate the surrounding environment; the lighting assembly 4 and the warning light assembly 3 are stacked together and share the same mounting base.

[0027] The newly added lighting component 4 can emit a constant light to illuminate the surrounding environment, solving the problems of "poor visibility and easy collision" when drivers place warning signs at night or in low light conditions. At the same time, it avoids the inconvenience of carrying a separate lighting device, meeting the portability requirements of essential driving equipment. The lighting component 4 and the warning light component 3 are stacked and share a common mounting base, which does not require additional space. Compared with the "separate light assembly", it is more compact and small in size when folded, without affecting the overall portability of the device. It also avoids the structural complexity caused by the independent installation of the two light assemblies.

[0028] In another optional embodiment, the surfaces of the first reflector 21, the second reflector 22 and the third reflector 23 are all provided with a color marking layer. The structure of the color marking layer is as follows: the central area 51 is a red reflective coating or a red reflective film, and the outer ring 52 around the central area is a yellow reflective coating or a yellow reflective film.

[0029] In this embodiment, the color-coded layer design of "red in the center and yellow on the periphery" utilizes the high visibility of red (the core color for fault warning) and the strong penetrating power of yellow (easy to identify in low-light environments) to visually expand the warning range, allowing passing vehicles (especially drivers who are driving long distances or are fatigued) to spot the warning sign earlier. The reflective coating / film covers the entire reflective surface, providing a large reflective area and further improving the reliability of the warning at night or in adverse weather conditions (such as fog).

[0030] In another optional embodiment, the warning light assembly 3 is connected to the fixing plate 14 via a universal connector 6, the universal connector 6 including a lamp holder 61, a connecting rod 62, a sleeve 63, and a movable ball 64; the lamp holder 61 is used to fix the warning light assembly 3; the bottom of the sleeve 63 is integrally formed with the fixing plate 14 (i.e., the sleeve 63 directly serves as an integrated structure of the fixing plate 14, without the need for additional fixing connection), or the bottom of the sleeve 63 is fixedly connected to the top surface of the fixing plate 14; the sleeve 63 is open at the top. The sleeve 63 has an open structure with a hollow interior and a small opening on its side that communicates with the upper opening. The movable ball 64 is rotatably disposed in the hollow cavity of the sleeve 63. One end of the connecting rod 62 is fixedly connected to the lamp holder 61, and the other end passes through the upper opening of the sleeve 63, extends into the hollow cavity, and is fixedly connected to the movable ball 64. The upper opening of the sleeve 63 provides space for the rotation of the connecting rod 62. The small opening is used to cooperate with the locking component to tighten or loosen the movable ball 64, so as to adjust or fix the rotation state of the movable ball 64.

[0031] In this embodiment, the structure of "movable ball 64 + coverless sleeve 63" can drive the warning light to rotate in multiple directions around the axis of sleeve 63, and can adjust the warning angle according to the actual road conditions (such as sloping roads and curves) to ensure that passing vehicles can clearly see the warning signal from different directions.

[0032] In another optional embodiment, the universal connector 6 is also equipped with a locking wrench 65, which is threaded to the outer wall of the sleeve 63, and one end of the locking wrench 65 extends into the hollow cavity of the sleeve 63, thereby restricting rotation or restoring rotation by pressing against or releasing the movable ball 64.

[0033] In another optional embodiment, the bottom surface of the fixing plate 14 is provided with at least two pairs of parallel vertical plates 7; each pair of vertical plates 7 is provided with coaxial hinge holes; by rotating the connecting nail 8 through the hinge holes of a pair of vertical plates 7 and the through holes of the corresponding reflector head and / or the corresponding support leg head, the plates are hinged to each other.

[0034] In another optional embodiment, the inner wall of the sleeve 63 is provided with a wear-resistant coating, and the outer surface of the movable ball 64 is provided with a smooth wear-resistant layer; the wear-resistant coating and the smooth wear-resistant layer work together to reduce the frictional loss between the movable ball 64 and the inner wall of the sleeve 63 when the ball rotates.

[0035] In another optional embodiment, a control module is also included; the control module includes a mode switching switch, a microcontroller unit (MCU), and a driving circuit; the mode switching switch is electrically connected to the input terminal of the MCU and is used to input a mode selection signal for constant light, slow flashing, strobe, and SOS distress signal to the MCU; the output terminal of the MCU is electrically connected to the LED light board through the driving circuit to drive the LED light board to work according to the selected mode.

[0036] In another optional embodiment, a power supply module is also included; the power supply module includes a standard battery compartment, a USB-C charging port, a built-in rechargeable battery, a charging management circuit, and a power management circuit; the standard battery compartment is compatible with various types of dry cell batteries, and the USB-C charging port is electrically connected to the built-in rechargeable battery through the charging management circuit for charging the rechargeable battery; the input terminal of the power management circuit is electrically connected to the standard battery compartment and the built-in rechargeable battery respectively, and the output terminal is electrically connected to the lamp body module and the control module respectively, providing adaptive operating voltage for both; the power supply module also supports three power supply methods: dry cell battery power supply, built-in rechargeable battery power supply, and USB external power supply.
