Description

Technical Field

[0001] The present invention relates to an anti-collision warning device, and particularly to an anti-collision warning device for automobiles applied in the field of automotive safety technology. Background Art

[0002] An automobile is a vehicle driven by a power device (such as an internal combustion engine, an electric motor) and having four or more wheels, mainly used for carrying people or goods. In the usage scenarios of automobiles, it is inevitable to encounter situations where it is necessary to drive onto a curb. In order to drive onto the curb smoothly, the vehicle chassis not only has to be higher than the curb but also leave a certain safety gap, otherwise it is easy to cause a collision between the chassis and the curb, resulting in vehicle damage.

[0003] In the prior art, a Chinese patent with the publication number CN103538522B discloses a reverse anti-collision warning device, and a Chinese patent with the publication number CN110154892B discloses a night parking lot automobile anti-collision warning device. Although the above two patents can respectively improve the safety of automobiles when reversing and when parked in a parking lot, neither of them involves the dynamic collision risk between the vehicle bottom and the curb.

[0004] Currently, the protection against chassis collision risks in the industry still relies on passive measures, such as installing a metal guard plate or increasing the chassis stiffness. However, such solutions can only reduce the degree of damage and cannot achieve active warning and avoidance. Therefore, we propose an anti-collision warning device for automobiles. Summary of the Invention

[0005] Aiming at the above-mentioned prior art, the technical problem to be solved by the present invention is: how to give an active warning when the chassis may collide with the curb to avoid the collision.

[0006] To solve the above problems, the present invention provides an anti-collision warning device for automobiles, including a support box and an anti-collision detection and warning system. The support box is fixedly installed at the front of the automobile. An electric push rod vertically downward is fixedly installed in the support box. The output end of the electric push rod is fixedly connected with a connecting plate. A pressure sensor is fixedly installed at the bottom end of the connecting plate. An anti-collision gap measuring rod is arranged directly below the pressure sensor. A through support rod is arranged in the support box. A through connection groove matching the through support rod is opened on the anti-collision gap measuring rod. The through support rod penetrates through the through connection groove and is slidably connected therewith, and the through support rod is fixedly connected with the connecting plate. The top end of the anti-collision gap measuring rod abuts against the pressure sensor. The bottom end of the anti-collision gap measuring rod penetrates through the bottom outer wall of the support box and is slidably connected therewith. The bottom end of the anti-collision gap measuring rod is flush with the chassis of the automobile; The anti-collision detection and warning system includes a clearance control module, an analysis and warning control module, and an alarm reminder module. The clearance control module is signal-connected to the electric push rod, the pressure sensor is signal-connected to the analysis and warning control module, and the analysis and warning control module is signal-connected to both the clearance control module and the alarm reminder module. A safety threshold is preset in the clearance control module, and the value of the safety threshold is 3 - 8 cm.

[0007] In the above-mentioned anti-collision warning device for vehicles, before the vehicle drives onto the curb, it will test whether there is enough safety clearance between the vehicle chassis and the curb, and will give an active warning when the safety clearance is insufficient, which can fundamentally avoid the risk of collision between the chassis and the curb.

[0008] As a further improvement of this application, a buffer and measurement enhancement groove is provided at the top end of the anti-collision clearance rod. A pressure transmission block matching the buffer and measurement enhancement groove is movably arranged in the buffer and measurement enhancement groove. A pressure application spring is fixedly installed on the inner wall of the bottom end of the buffer and measurement enhancement groove, and the top end of the pressure application spring is fixedly connected to the bottom end of the pressure transmission block. A sliding groove matching the anti-collision clearance rod is provided at the bottom end of the support box, and the anti-collision clearance rod penetrates through the sliding groove and is slidably connected thereto.

[0009] As a further improvement of this application, the pressure application spring is in a compressed state, the top end of the pressure transmission block is flush with the top end of the anti-collision clearance rod, and the pressure transmission block abuts against the pressure sensor.

[0010] As a further improvement of this application, the through support rod is set in a U shape, and a pair of return springs are sleeved on the through support rod, and the pair of return springs are respectively located on the left and right sides of the anti-collision clearance rod.

[0011] As a further improvement of this application, limiting spring plates matching the anti-collision clearance rod are provided on both the left and right sides of the anti-collision clearance rod. The limiting spring plates are fixedly connected to the through support rod, and the bottom end of the limiting spring plate is flush with the top end of the anti-collision clearance rod.

[0012] As another improvement of this application, an elastic water bag is also fixedly installed on the outer wall of the support box. The elastic water bag is made of an elastic material and is filled with water inside. A water guide hose is communicated with the side wall of the elastic water bag, and the end of the water guide hose far away from the elastic water bag is communicated with the buffer and measurement enhancement groove.

[0013] As a supplement to another improvement of this application, the buffer and measurement enhancement groove is also filled with water. The pressure transmission block is slidably and sealingly connected to the buffer and measurement enhancement groove, and the bottom end of the elastic water bag is flush with the bottom end of the anti-collision clearance rod.

[0014] As a supplement to another improvement of this application, the anti-collision detection and warning system further includes a vehicle speed acquisition module and a speed-dependent regulation module. The vehicle speed acquisition module is signal-connected to the speed-dependent regulation module, and the speed-dependent regulation module is signal-connected to the pressure sensor. The vehicle speed acquisition module is used to obtain the real-time vehicle speed.

[0015] As a supplement to another improvement of the present application, a vehicle speed threshold is preset in the speed-dependent control module. When the real-time vehicle speed is not less than the vehicle speed threshold, the speed-dependent control module turns off the pressure sensor. When the real-time vehicle speed is less than the vehicle speed threshold, the speed-dependent control module activates the pressure sensor.

[0016] In summary, the anti-collision warning device in the present application can test whether there is a sufficient safety gap between the vehicle chassis and the curb before the vehicle drives onto the curb, and can give an active warning when the detected safety gap is insufficient, so as to fundamentally avoid the risk of collision between the chassis and the curb, improving the safety of the vehicle; through the combined setting of the buffer protection and additional measurement groove, the pressure spring, the pressure transmission block, etc., not only can a buffering effect be provided without affecting the test results, effectively avoiding damage to the electric push rod, the pressure sensor, etc., but also further testing can be achieved to avoid inaccurate test results caused by the inclined curb, thereby improving the comprehensiveness and accuracy of the test, and further avoiding the risk of collision between the chassis and the curb; through the combined setting of the elastic water bag, the water guide hose, etc., when the vehicle approaches the curb, if the vehicle chassis is lower than the curb, the anti-collision warning device will also emit an alarm sound for warning, thereby effectively preventing the collision between the vehicle head and the curb, further improving the safety of the vehicle.

[0019] The following will make a detailed description of two implementation manners of the present application in conjunction with the accompanying drawings.

[0020] The first implementation manner: Figures 1 - 5 There is shown an anti-collision warning device for an automobile, including a support box 101 and an anti-collision warning system. The support box 101 is fixedly installed at the front of the automobile. An electric push rod 102 arranged vertically downward is fixedly installed in the support box 101. The output end of the electric push rod 102 is fixedly connected with a connecting plate 103. A pressure sensor 104 is fixedly installed at the bottom end of the connecting plate 103. An anti-collision gap measuring rod 105 is arranged directly below the pressure sensor 104. A through-support rod 106 is arranged in the support box 101. A through-connection groove 107 matching the through-support rod 106 is formed on the anti-collision gap measuring rod 105. The through-support rod 106 penetrates through the through-connection groove 107 and is slidably connected therewith, and the through-support rod 106 is fixedly connected with the connecting plate 103. The top end of the anti-collision gap measuring rod 105 abuts against the pressure sensor 104. The bottom end of the anti-collision gap measuring rod 105 penetrates through the bottom outer wall of the support box 101 and is slidably connected therewith. The bottom end of the anti-collision gap measuring rod 105 is flush with the chassis of the automobile; The anti-collision warning system includes a gap measuring control module, an analysis and warning control module, and an alarm reminder module. The gap measuring control module is in signal connection with the electric push rod 102. The pressure sensor 104 is in signal connection with the analysis and warning control module. The analysis and warning control module is in signal connection with both the gap measuring control module and the alarm reminder module. A safety threshold is preset in the gap measuring control module, and the value of the safety threshold is 3 - 8 cm.

[0021] The anti-collision warning system can be integrated into the central control system of the automobile or can be integrated into an independent controller (if integrated into the controller, the controller needs to be installed in the cab). The vehicle owner (driver of the vehicle) can send instructions to the gap measuring control module through corresponding means (such as buttons on the central console or buttons on the controller, etc.). This is prior art and will not be elaborated here.

[0022] When the vehicle needs to drive onto the curb, the vehicle owner can first drive the vehicle slowly towards the curb until the anti-collision clearance rod 105 moves above the curb. Then, a test instruction is sent to the clearance control module. After receiving the instruction, the clearance control module will control the electric push rod 102 to push the anti-collision clearance rod 105 downward according to the preset safety threshold (the distance that the anti-collision clearance rod 105 moves downward is equal to the safety threshold). During the downward movement of the anti-collision clearance rod 105, if the bottom end of the anti-collision clearance rod 105 touches the curb, it means that although the vehicle chassis is higher than the curb, the gap between the two is less than the safety threshold, and the safety clearance is insufficient. If the vehicle drives onto the curb, there is a greater risk of collision between the chassis and the curb. Since the anti-collision clearance rod 105 touching the curb will cause the pressure data measured by the pressure sensor 104 to increase significantly, and the pressure data measured by the pressure sensor 104 is transmitted to the analysis and warning module in real time, enabling the analysis and warning module to discover this situation by analyzing the pressure data. At this time, the analysis and warning module will immediately send a signal to the clearance control module to prompt the clearance control module to stop controlling the electric push rod 102 from pushing the anti-collision clearance rod 105 in time to prevent damage to the electric push rod 102, the pressure sensor 104, etc. At the same time, the analysis and warning module will control the alarm reminder module to emit an alarm sound to warn the vehicle owner, causing the vehicle owner to give up driving onto the curb; On the contrary, if the pressure data measured by the pressure sensor 104 does not increase significantly until the anti-collision clearance rod 105 finishes moving downward, it means that the bottom end of the anti-collision clearance rod 105 does not touch the curb, and the gap between the vehicle chassis and the curb is not less than the safety threshold, with sufficient safety clearance. The vehicle can safely drive onto the curb. At this time, the analysis and warning module will control the alarm reminder module to emit a prompt sound representing safety. After hearing the prompt sound, the vehicle owner can carefully drive the vehicle onto the curb; In addition, in some similar scenarios, such as when the vehicle needs to pass over a raised obstacle, the above operations can also be carried out. First, test, and then based on the test results and feedback, choose whether to continue passing or give up passing; Therefore, the anti-collision alarm device in this application can test whether there is sufficient safety clearance between the vehicle chassis and the curb before the vehicle drives onto the curb, and can give an active warning when the safety clearance is insufficient, so as to fundamentally avoid the risk of collision between the chassis and the curb and improve the safety of the vehicle.

[0023] The top end of the anti-collision clearance measuring rod 105 is provided with a buffer and clearance increasing groove 201. A pressure transmission block 203 matching with the buffer and clearance increasing groove 201 is movably arranged in the buffer and clearance increasing groove 201. A pressure applying spring 202 is fixedly installed on the inner wall of the bottom end of the buffer and clearance increasing groove 201. The top end of the pressure applying spring 202 is fixedly connected with the bottom end of the pressure transmission block 203. The bottom end of the support box 101 is provided with a sliding groove 108 matching with the anti-collision clearance measuring rod 105. The anti-collision clearance measuring rod 105 penetrates through the sliding groove 108 and is slidably connected with the sliding groove 108. The pressure applying spring 202 is in a compressed state. The top end of the pressure transmission block 203 is flush with the top end of the anti-collision clearance measuring rod 105, and the pressure transmission block 203 abuts against the pressure sensor 104.

[0024] When the safety clearance is insufficient, that is, when the anti-collision clearance measuring rod 105 touches the curbstone during the downward movement, in order to further prevent the electric push rod 102, the pressure sensor 104, etc. from being damaged, the buffer and clearance increasing groove 201, the pressure applying spring 202, and the pressure transmission block 203 are provided. Under the combined action of the buffer and clearance increasing groove 201, the pressure applying spring 202, and the pressure transmission block 203, a buffering effect can be provided without affecting the test result, effectively avoiding the damage of the electric push rod 102, the pressure sensor 104, etc. In addition, the curbstone may also be inclined. If the curbstone is inclined upward along the forward direction of the vehicle, even if the current test result shows that there is sufficient safety clearance, the vehicle chassis may still collide with the curbstone. In order to avoid this phenomenon, after the vehicle owner hears the prompt sound representing safety, the vehicle can be slowly driven forward until the front wheels of the vehicle abut against the curbstone. Since the pressure transmission block 203 is in a compressed state, although the anti-collision clearance measuring rod 105 does not touch the curbstone, the pressure sensor 104 will also receive a certain pressure. During the continuous forward movement of the vehicle, if the curbstone is inclined and the highest point is higher than the bottom end of the anti-collision clearance measuring rod 105 at this time, then the anti-collision clearance measuring rod 105 will be pushed, resulting in the separation of the anti-collision clearance measuring rod 105 from the pressure sensor 104, thereby causing the pressure data measured by the pressure sensor 104 to decrease significantly. Therefore, the analysis and control alarm module can know this situation by analyzing the pressure data. At this time, the analysis and control alarm module will control the alarm reminder module to emit an alarm sound, causing the vehicle owner to brake in time and stop moving forward and give up driving onto the curbstone. On the contrary, if the vehicle owner does not hear the alarm sound until the front wheels abut against the curbstone, it means that the vehicle owner can drive the vehicle onto the curbstone. At this time, the vehicle owner can issue a reset command to the clearance measuring control module, and then can carefully drive onto the curbstone. After receiving the reset command, the clearance measuring control module will control the electric push rod 102 to drive the anti-collision clearance measuring rod 105 to move upward for reset. In addition, after hearing the alarm sound, the vehicle owner also needs to issue a reset command to the clearance measuring control module. Therefore, through the combined setting of the buffer and measurement-increasing groove 201, the pressure-applying spring 202, the pressure-transmitting block 203, etc., not only can a buffering effect be provided without affecting the test results, effectively avoiding damage to the electric push rod 102, the pressure sensor 104, etc., but also further tests can be realized, avoiding inaccurate test results caused by the inclined curbstone, thereby improving the comprehensiveness and accuracy of the test, and further avoiding the risk of collision between the chassis and the curbstone.

[0025] The support rod 106 is arranged in a U shape, and a pair of restoring springs 110 are sleeved on the support rod 106. The pair of restoring springs 110 are respectively located on the left and right sides of the anti-collision clearance rod 105, so that the anti-collision clearance rod 105 can automatically reset after being pushed by the inclined curbstone. Limiting spring plates 109 are arranged on the left and right sides of the anti-collision clearance rod 105 and are fixedly connected with the support rod 106. The bottom end of the limiting spring plate 109 is flush with the top end of the anti-collision clearance rod 105. The limiting spring plate 109 can prevent the pressure-transmitting block 203 from popping out of the buffer and measurement-increasing groove 201, thus being beneficial to the automatic reset of the anti-collision clearance rod 105.

[0026] The second implementation mode: Figures 6 - 9 A car anti-collision warning device is shown. Different from the first implementation mode, an elastic water bag 301 is also fixedly installed on the outer wall of the support box 101. The elastic water bag 301 is made of an elastic material and filled with water. A water guide hose 302 is communicated with the side wall of the elastic water bag 301. One end of the water guide hose 302 far away from the elastic water bag 301 is communicated with the buffer and measurement-increasing groove 201, and the buffer and measurement-increasing groove 201 is also filled with water. The pressure-transmitting block 203 is slidably and hermetically connected with the buffer and measurement-increasing groove 201. The bottom end of the elastic water bag 301 is flush with the bottom end of the anti-collision clearance rod 105.

[0027] Before starting the test, when the vehicle approaches the curb, if the curb is higher than the vehicle chassis, it will cause the front of the vehicle or the support box 101 to collide with the curb. To avoid this phenomenon, in this embodiment, when the vehicle approaches the curb and the curb is higher than the vehicle chassis, before the front of the vehicle or the support box 101 collides with the curb, the elastic water bag 301 will be squeezed by the curb first. When the elastic water bag 301 is squeezed, the water in the elastic water bag 301 will be squeezed, which will cause the pressure transfer block 203 to receive an upward thrust, and further cause the pressure received by the pressure sensor 104 to increase. After the analysis and control alarm module discovers this situation by analyzing the pressure data, it will control the alarm reminder module to emit an alarm sound, causing the vehicle owner to brake in time and stop moving forward. Therefore, through the combined setting of the elastic water bag 301, the water guide hose 302, etc., when the vehicle approaches the curb, if the vehicle chassis is lower than the curb, the anti-collision alarm device will also emit an alarm sound for warning, thus effectively preventing the front of the vehicle from colliding with the curb and further improving the safety of the vehicle.

[0028] The anti-collision detection and alarm system further includes a vehicle speed acquisition module and a speed-dependent regulation module. The vehicle speed acquisition module is signal-connected to the speed-dependent regulation module, and the speed-dependent regulation module is signal-connected to the pressure sensor 104. The vehicle speed acquisition module is used to obtain the real-time vehicle speed. When the vehicle speed is relatively fast, the airflow impact on the elastic water bag 301 will also cause the pressure received by the pressure sensor 104 to increase, which may lead to false alarms. To avoid this phenomenon, a vehicle speed threshold is preset in the speed-dependent regulation module. When the real-time vehicle speed is not less than the vehicle speed threshold, the speed-dependent regulation module will turn off the pressure sensor 104, thus effectively avoiding false alarms. When the real-time vehicle speed is less than the vehicle speed threshold, the speed-dependent regulation module will activate the pressure sensor 104, thus ensuring the effectiveness of the anti-collision alarm device.

[0029] Combined with the current actual needs, the above-mentioned embodiment adopted in this application, the protection scope is not limited to this. Within the knowledge scope of those skilled in the art, various changes made without departing from the concept of this application still fall within the protection scope of the present invention.
