Description

Technical Field

[0001] The invention relates to the technical field of alarms, in particular to a vehicle anti-collision alarm device. Background Art

[0002] Vehicle collision avoidance alarm devices generally use radar for ranging, which is used to detect the distance of obstacles in front of the car while the vehicle is driving, provide information such as the distance, direction, and area of ​​the obstacle, and issue an alarm in a timely manner, providing convenience for drivers to park, drive slowly, follow the vehicle, change lanes in congestion, etc., and help them reduce or eliminate collisions, scratches and other accidents caused by poor visibility when moving forward.

[0003] In the prior art, there is a radar bracket and a vehicle with publication number CN217994309U, wherein the radar bracket comprises a top plate, a connecting plate and a side plate connected in sequence, wherein the top plate and the side plate are perpendicular to each other, the angle between the connecting plate and the top plate is an obtuse angle, the angle between the connecting plate and the side plate is an obtuse angle, the top plate is used to install the radar, and the side plate is used to connect to the vehicle body. The radar bracket sets the angle between the connecting plate and the side plate to an obtuse angle, and the angle between the connecting plate and the top plate is also set to an obtuse angle, so that when the top plate moves toward the side plate, the top plate can move relative to the side plate, so that when the radar bracket collides with a pedestrian, the radar bracket has a certain amount of collapse, thereby playing a buffering role, minimizing the shear damage to the human leg, and avoiding sacrificing the aesthetic appearance of the vehicle, the overall optimal wind resistance, and the requirements for radar use accuracy and strength; such as an anti-collision millimeter wave radar for autonomous driving vehicles with publication number CN221162511U. The invention sets the radar body on the inner wall of the anti-collision box and opens a signal transmitting port on the opposite side wall of the radar body, so that the radar body can normally emit millimeter waves outward and receive the target reflection signal in time, which can not only protect the millimeter-wave radar, but also will not interfere with the automatic driving vehicle to make correct judgments and avoid causing harm; the invention fixes one end of the telescopic rod 1 wrapped with shock-absorbing spring 1 and the telescopic rod 2 wrapped with shock-absorbing spring 2 on the inner wall of the anti-collision box and the other end on the anti-collision plate with a width greater than the anti-collision box, so that the anti-collision box can continuously protect the millimeter-wave radar without millimeter-wave radar analysis. When a collision occurs at a high speed, the anti-collision plate cooperates with the telescopic rod 1, telescopic rod 2, shock-absorbing spring 1 and shock-absorbing spring 2 to buffer the force of the collision, prevent damage to the millimeter-wave radar, and reduce the economic loss of the car owner;

[0004] Although the existing vehicle anti-collision alarm device can achieve collapse buffering during use, its radar transmitter head lacks protection during the collapse process, which makes it easy to be damaged by friction. In addition, when the existing vehicle anti-collision alarm device is installed, the wiring method is single, which makes the wiring easy to loosen during the operation of the vehicle, and the wiring sealing effect is limited, which affects the normal use of the radar and has certain usage defects. Summary of the invention

[0005] The purpose of the present invention is to provide a vehicle anti-collision alarm device to solve the problem raised in the above background technology that although the vehicle anti-collision alarm device currently on the market can achieve collapse buffering during use, its radar transmitter head lacks protection during the collapse process, which makes it easy to be damaged by friction, and the existing vehicle anti-collision alarm device has a single wiring method during installation, which makes the wiring easy to loosen during the operation of the vehicle, and the wiring sealing effect is limited, thereby affecting the normal use of the radar.

[0006] To achieve the above object, the present invention provides the following technical solution: a vehicle anti-collision alarm device, comprising a mounting base fixedly mounted on a vehicle by bolts, wherein a radar is telescopically connected to the inner side of the mounting base, and a transmitter is arranged at the left end of the radar, and a female terminal is installed at the right end of the radar, and a male terminal is plugged and connected to the outer side of the female terminal;

[0007] It also includes: a protection seat, fixedly installed on the outer side of the left end of the radar, the protection seat is arranged in an annular structure, and a rotating disk is rotatably installed on the inner side of the protection seat, and rotating blocks are evenly arranged between the protection seat and the rotating disk, and the rotating blocks are elastically rotatably connected to the inner side of the protection seat, and a slider is fixedly installed on the outer side of the rotating block;

[0010] The elastic clips are evenly arranged on the right side of the radar.

[0011] Preferably, the mounting seat is mounted on the outside of the radar, and the radar forms an elastic telescopic structure through an elastic telescopic component and the mounting seat.

[0012] By adopting the above technical solution, when the vehicle is accidentally hit, the radar will be forced to slide elastically along the inner side of the mounting seat, thereby achieving buffering and preventing the radar from being damaged due to excessive impact.

[0013] Preferably, a sleeve is fixedly provided at the left end of the wiring male socket, and positioning grooves are evenly opened on the outer wall of the sleeve, and the elastic clip forms a snap-fit ​​structure with the slide groove after deformation.

[0014] By adopting the above technical solution, the elastic clip can be inserted into the positioning groove after elastic deformation, so as to realize the positioning of the sleeve, thereby improving the connection stability of the female terminal socket and the male terminal socket.

[0015] Preferably, an air storage bag is embedded and installed on the inner side of the positioning groove, and a sealing air bag is embedded and installed on the inner wall of the sleeve, and the air storage bag and the sealing air bag are connected by a pipeline.

[0016] By adopting the above technical solution, when the elastic clip is inserted into the positioning groove, it will squeeze the air storage bag, so that part of the gas in the air storage bag enters the sealed air bag through the pipeline, thereby increasing the internal air pressure of the sealed air bag and causing it to expand.

[0017] Preferably, the sealing airbag is arranged in an annular structure, and after the sealing airbag is expanded, it fits tightly between the terminal socket and the sleeve.

[0018] By adopting the above technical solution, the sealing airbag can improve the connection sealing of the terminal socket and the terminal male socket after expansion, thereby achieving effective waterproof connection. At the same time, the inflated sealing airbag can apply pressure to the terminal socket and the sleeve, thereby further preventing the two from slipping.

[0020] By adopting the above technical solution, when the radar and the mounting seat are elastically extended and retracted, the limit block on the inner wall of the mounting seat will slide against the outer side of the elastic clip, so that the elastic clip is compressed and elastically deformed, thereby ensuring that the elastic clip can be stuck in the positioning groove.

[0022] By adopting the above technical solution, when the radar is accidentally hit, the protective seat will drive the radar to slide to the right, so that the right end of the elastic telescopic component slides against the inclined surface of the inclined block, thereby prompting the rotating disk to rotate automatically.

[0023] Preferably, the elastic telescopic assembly comprises a fixed cylinder fixedly mounted on the outer side of the rotating disk, and a telescopic rod is telescopically connected to the inner side of the fixed cylinder, and a spring is connected between the fixed cylinder and the telescopic rod.

[0025] Preferably, arc-shaped slide grooves are evenly opened on the rotating disk, a rotating block is evenly and elastically rotatably installed on the inner side of the protective seat, and a slider is fixedly installed on the outer side of the rotating block, and the slider is slidably connected to the slide groove, and multiple rotating blocks are fitted together after rotation.

[0026] By adopting the above technical solution, when the radar is elastically extended and retracted, the rotating disk will rotate, thereby driving multiple rotating blocks to rotate and fit simultaneously.

[0027] Preferably, the rotating block penetrates the inner wall of the protective seat during rotation, and the rotating block is located outside the transmitting head.

[0028] By adopting the above technical solution, when the rotating block rotates and fits, a disc structure can be formed on the outside of the transmitter head, thereby achieving covering protection for the transmitter head, effectively preventing foreign objects from contacting the outer wall of the transmitter head during collision and causing friction and damage to the transmitter head, further improving the protection effect of the equipment.

[0029] Compared with the prior art, the beneficial effects of the present invention are: the vehicle anti-collision alarm device can perform elastic collapse buffering when subjected to an unexpected collision, and can effectively protect the transmitter head during the buffering process, and the wiring is stable and the waterproof effect is good. The specific contents are as follows;

[0030] 1. A radar, a mounting seat, a fixed tube and a telescopic rod are provided. When the radar is hit accidentally, the radar will slide and collapse to the inside of the mounting seat. At this time, the fixed tube and the telescopic rod will elastically contract. Under the elastic force of the spring, a buffering effect is achieved, which effectively prevents the radar from being damaged due to excessive impact.

[0031] 2. A protective seat, a rotating disk and a rotating block are provided. When the radar is buffered and collapsed, the telescopic rod will slide along the inclined surface of the inclined block, thereby driving the rotating disk to rotate through the fixed tube. When the rotating disk rotates, it will drive multiple rotating blocks to extend from the inner side of the protective seat and rotate and fit together to cover and protect the transmitter head, avoiding contact and wear of the transmitter head by external objects during the collision process, further improving the protection effect;

[0032] 3. A wiring female seat, a wiring male seat and a sealing airbag are provided. When wiring is performed, the radar and the mounting seat are manually pressed to elastically contract, and then the wiring female seat and the wiring male seat are plugged in. When the radar and the mounting seat are released, multiple sets of elastic clips will be deformed under pressure and then fix the sleeve. At the same time, the gas inside the air storage bag and the sealing airbag flows tightly, so that the sealing airbag is pressurized and expanded and closely fits to the outside of the wiring female seat and the sleeve, so as to achieve stable sealing and connection of the wiring female seat and the wiring male seat, and effectively improve the circuit installation effect of the equipment.

DETAILED DESCRIPTION

[0042] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0043] Example 1: Please refer to Figure 1-Figure 2 and Figure 7-Figure 8 As shown, the existing vehicle anti-collision alarm device has a single wiring structure during use, which makes the sealing effect of the wiring point limited and cannot be effectively waterproof. In order to solve this technical problem, the present embodiment discloses the following technical content: a vehicle anti-collision alarm device, including a mounting base 3 fixedly installed on the vehicle by bolts, and the inner side of the mounting base 3 is telescopically connected with a radar 1, and the left end of the radar 1 is provided with a transmitter 2, and at the same time, a wiring female seat 4 is installed at the right end of the radar 1, and the outer side of the wiring female seat 4 is plugged and connected with a wiring male seat 5; a limit block 16 is fixedly installed on the inner wall of the mounting base 3; and elastic clips 17 are evenly arranged on the right side of the radar 1.

[0044] The mounting seat 3 is sleeved on the outer side of the radar 1 , and the radar 1 forms an elastic telescopic structure through the elastic telescopic component and the mounting seat 3 .

[0045] A sleeve 501 is fixedly provided at the left end of the wiring male socket 5 , and positioning grooves 502 are evenly formed on the outer wall of the sleeve 501 , and the elastic clip 17 forms a snap-fit ​​structure with the slide groove 15 after deformation.

[0046] An air storage bag 503 is embedded and installed inside the positioning groove 502, and a sealing air bag 504 is embedded and installed inside the inner wall of the sleeve 501, and the air storage bag 503 and the sealing air bag 504 are connected by a pipeline. The sealing air bag 504 is arranged in an annular structure, and after the sealing air bag 504 is expanded, it is tightly fitted between the wiring female seat 4 and the sleeve 501. The positions of the limit block 16 and the elastic clip 17 are correspondingly arranged, and the limit block 16 slides in contact with the edge of the elastic clip 17.

[0047] By adopting the above technical solution, when the equipment needs to be installed, the radar 1 and the mounting seat 3 are manually pressed to make the two elastically contract, and then the female terminal seat 4 and the male terminal seat 5 are plugged in. After the plugging is completed, the radar 1 and the mounting seat 3 are released. At this time, the limit block 16 on the inner side of the mounting seat 3 will slide along the outer wall of the elastic clip 17, so that the elastic clip 17 is resisted and elastically deformed. The deformed elastic clip 17 is snapped into the positioning groove 502 to limit the male terminal seat 5. At the same time, the elastic clip 17 The air storage bag 503 will be squeezed, so that part of the gas in the air storage bag 503 enters the sealing air bag 504 through the pipeline, causing the sealing air bag 504 to expand and deform. The expanded sealing air bag 504 will fit tightly to the wiring mother seat 4 and the sleeve 501, achieving effective sealing and waterproofing at the connection point, and then the mounting seat 3 and the vehicle shell are fixed by bolts to achieve convenient installation of the equipment. When the wiring mother seat 4 and the wiring male seat 5 need to be disassembled, the radar 1 is pressed to make the radar 1 and the mounting seat 3 elastically shrink. At this time, the limit block 16 slides and resets along the outer wall of the elastic clip 17, thereby releasing the limit on the elastic clip 17, so that the elastic clip 17 elastically recovers under the action of the self-generated elastic force, so that the end of the elastic clip 17 is automatically taken out of the positioning groove 502, thereby releasing the lock, and at the same time, part of the gas in the sealing air bag 504 will return to the air storage bag 503 again through the gas pipeline, so that the wiring mother seat 4 and the wiring male seat 5 can be pulled out.

[0048] Embodiment 2: The technical content disclosed in this embodiment is a further improvement made on the basis of the above-mentioned embodiment 1. Although the existing vehicle anti-collision alarm device can collapse when it is hit by an accident, it is inconvenient to effectively protect the impacted surface during the collapse process. In order to further solve this technical problem, this embodiment discloses the following technical content, such as Figure 1-Figure 6As shown, the protection seat 6 is fixedly installed on the outer side of the left end of the radar 1, the protection seat 6 is arranged in an annular structure, and a rotating disk 7 is rotatably installed on the inner side of the protection seat 6, and a rotating block 13 is evenly arranged between the protection seat 6 and the rotating disk 7, and the rotating block 13 is elastically rotatably connected to the inner side of the protection seat 6, and a slider 14 is fixedly installed on the outer side of the rotating block 13;

[0049] The elastic telescopic component is installed on the right side of the rotating disk 7. The telescopic component passes through the slide slot 15 provided on the protective seat 6. The right end of the telescopic component is fitted with an inclined block 12, and the inclined block 12 is fixedly installed on the outer side of the left end of the mounting seat 3.

[0050] The elastic telescopic assembly includes a fixed cylinder 9 fixedly mounted on the outer side of the rotating disk 7 , and a telescopic rod 10 is telescopically connected to the inner side of the fixed cylinder 9 , and a spring 11 is connected between the fixed cylinder 9 and the telescopic rod 10 .

[0051] Arc-shaped slide grooves 15 are evenly opened on the rotating disk 7, and a rotating block 13 is evenly and elastically rotatably installed on the inner side of the protective seat 6, and a slider 14 is fixedly installed on the outer side of the rotating block 13, and the slider 14 is slidably connected to the slide groove 15, and multiple rotating blocks 13 are fitted together after rotation; the rotating block 13 penetrates the inner wall of the protective seat 6 during rotation, and the rotating block 13 is located on the outer side of the transmitting head 2.

[0052] When the radar 1 is hit unexpectedly, the radar 1 will drive the right end of the telescopic rod 10 to slide along the inclined block 12 through the fixed tube 9 (at this time, the fixed tube 9 and the telescopic rod 10 will not be telescopically adjusted under the elastic force of the spring 11), and can synchronously drive the fixed tube 9 to slide along the through groove 8, thereby driving the rotating disk 7 to rotate synchronously. At this time, the rotating disk 7 will drive the slider 14 to slide along the slide groove 15, thereby driving multiple rotating blocks 13 to rotate synchronously and fit together, so as to cover and protect the transmitter 2. As the impact progresses, the radar 1 will slide toward the inside of the mounting seat 3, and the fixed tube 9 and the telescopic rod 10 will elastically contract, thereby achieving buffering of the radar 1 under the elastic force of the spring 11, thereby reducing the impact force on the radar 1 and avoiding damage.

[0053] The contents not described in detail in this specification belong to the prior art known to professional and technical personnel in this field.

[0054] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein.
