[0023] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the drawings are exemplary and are only used to explain the present invention and should not be construed as a limitation to the present invention.

[0024] In the description of the present invention, it should be noted that unless otherwise clearly defined and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0025] Next, refer to Figures 1-3 Describe the burner 100 for door verification according to an embodiment of the present invention.

[0026] As Figure 1 and Figure 2 shown, the burner 100 for door verification according to an embodiment of the present invention includes a combustion table 1, a plurality of combustion units 2, and a lifter 3.

[0027] The combustion table 1 can be placed under the vehicle 1000 or a separate door. The combustion unit 2 is arranged on the combustion table 1. Thus, the combustion unit 2 on the combustion table 1 can be close to the vehicle 1000 or the door, so as to ignite the vehicle 1000 or the door and simulate the scene of the vehicle 1000 or the door burning.

[0028] Each combustion unit 2 has at least one combustion hole 21 for supplying combustible gas. It can be understood that each combustion unit 2 can also include two combustion holes 21 or a greater number of combustion holes 21, such as Figure 1One combustion unit 2 includes two combustion holes 21, and the number of the combustion holes 21 is not limited herein. Each combustion unit 2 can be independently ignited and burned. When the combustion table 1 is placed under a vehicle 1000 or a car door and one or more combustion units 2 are ignited, the ignition range and combustion speed of the vehicle 1000 or the car door can be controlled. For example, when only one combustion unit 2 is ignited, a certain point of the vehicle 1000 or the car door can be ignited; for another example, when multiple combustion units 2 are ignited and the combustion units 2 are located at different positions of the combustion table 1, multiple parts of the vehicle 1000 or the car door can be ignited; for another example, when multiple combustion units 2 are ignited and the combustion units 2 are arranged adjacent to each other, one part of the vehicle 1000 or the car door can be ignited to increase the intensity of the flame here. The lifter 3 is connected to the combustion table 1 to control the height of the combustion table 1, or the lifter 3 is connected to at least one combustion unit 2 to control the height of the combustion unit 2. The lifter 3 can adapt to the heights of different vehicles 1000 and car doors, increasing the applicable range of the burner 100.

[0029] It should be further noted that the height of the lifter 3 can be remotely controlled, so as to stay away from the burning vehicle 1000 to protect the safety of the test personnel and improve the safety of the burner 100; or, the height of the lifter 3 can be manually adjusted and set in advance before ignition.

[0030] Different from the closest prior art, the burner 100 in the present application is used to test the door lock function of a vehicle 1000 or a car door under a combustion scenario. The laying of the combustion unit 2 and the setting of the lifter 3 in the present application are both to adapt to different conditions of the vehicle 1000 or the car door. For example, the sizes, materials, etc. of the vehicle 1000 or the car door vary due to different brands and manufacturers.

[0031] According to the burner 100 for door verification of the embodiment of the present utility model, the combustion holes 21 in the combustion unit 2 can supply combustible gas. After being ignited, a flame is formed at the combustion holes 21, burning and igniting the vehicle 1000 or a single car door. By integrating the combustion unit 2 on the combustion table 1, the stability and reliability of the operation of the combustion unit 2 can be improved. By connecting the lifter 3 to the combustion table 1 or the combustion unit 2, the height of the combustion table 1 or the combustion unit 2 can be adjusted to adapt to the heights of different vehicles 1000 or different car doors. By selecting the number of ignited combustion units 2, the combustion range and the intensity of the flame can be selected to simulate different combustion scenarios, increasing the applicable range of the burner 100 to meet the test requirements of different vehicles 1000 or car doors, and further the electric function of the door lock system of the vehicle 1000 or the car door under a combustion scenario can be detected and verified.

[0032] Such as Figure 2As shown, in some embodiments, a wire mesh 11 is provided on the combustion table 1, and particles 12 are laid on the wire mesh 11. The combustion holes 21 are located below the wire mesh 11. Combustible gas, such as methane, natural gas, etc., can be ejected from the combustion holes 21. The combustion holes 21 are arranged below the wire mesh 11, and the wire mesh 11 can suppress deflagration flames. Laying the particles 12 on the wire mesh 11 can prevent the combustion from being too intense, thereby reducing the explosion risk and further improving the safety of the burner 100. It can be understood that by placing the wire mesh 11 covered with particles 12 above the flame, the wire mesh 11 and the particles 12 can spread the towering flame into a fire net, increasing the flame distribution area, improving the combustion sufficiency of the vehicle 1000 or a single car door, and reducing the waste of combustible gas.

[0033] As Figure 2 shown, in some specific embodiments, the particles 12 are sand grains. The sand grains cover the wire mesh 11. The sand grains have low cost and can be reused, and can effectively reduce the explosion risk and improve the cost performance.

[0034] In addition, when the sand grains cover the wire mesh 11 and the flame intensity of the ignited burner 100 is small, the flame is blocked below the sand net formed by the sand grains, and only the temperature rises rapidly above. This can simulate the electrical performance of the door lock of the vehicle 1000 or a single car door in a high-temperature scenario. When the flame intensity of the ignited burner 100 is large, the flame can pass through the gaps between the sand grains and reach above the sand net, which can simulate the electrical performance of the door lock of the vehicle 1000 or a single car door in a combustion scenario.

[0035] As Figure 1 shown, in some embodiments, the burner 100 further includes a gas source pipe 4 and multiple branch pipes 5. One end of the branch pipe 5 is connected to the gas source pipe 4, and the other end of the branch pipe 5 is connected to at least one combustion unit 2 to supply gas to the combustion holes 21. The gas source pipe 4 can introduce combustible gas into the branch pipes 5. The gas source pipe 4 is a common gas transmission pipeline. According to the required flame height and width for testing, gas can be introduced into different branch pipes 5 to ignite different combustion units 2 and combustion holes 21, thereby controlling the range of the flame.

[0036] As Figure 1 shown, in some embodiments, the burner 100 further includes a pressure valve 6 provided corresponding to each branch pipe 5. The pressure valve 6 can detect and control the combustible gas in each branch pipe 5.

[0037] As Figure 1 shown, in some embodiments, the burner 100 further includes a pressure gauge 7 provided corresponding to each branch pipe 5. By setting the pressure gauge 7, the change in the combustion pressure in each branch pipe 5 can be detected, and the pressure condition in the branch pipe 5 can be transmitted to the pressure valve 6 to adjust the pressure valve 6.

[0038] As Figure 1As shown, in some embodiments, the burner 100 further includes at least one flow meter 8. The flow meter 8 is provided on the gas supply pipe 4 or each branch pipe 5, and can quantitatively control the combustible gas. When the combustible gas reaches a preset gas volume, the gas pressure valve 6 can be automatically cut off and closed to stop the gas supply.

[0039] As Figure 2 shown, in some embodiments, the lifter 3 includes a plurality of scissor lift frames. At least two scissor lift frames are connected to both ends of the combustion table 1. By providing a plurality of scissor lift frames, the balance and stability of the combustion table 1 can be improved, and the possibility of tipping can be reduced. The scissor lift frame can adopt the structure of the scissor lift mechanism known in the prior art. The scissor lift frame can be driven to lift electrically or manually controlled to lift.

[0040] As Figure 1 shown, exemplarily, the burner 100 further includes an ignition device 9 for electrically igniting at each combustion hole 21, which can ignite the combustible gas.

[0041] Specifically, the way the ignition device 9 performs electric ignition can adopt small fire ignition, electric spark ignition, electric heating wire ignition, etc. known in the prior art. For example, a household gas appliance can be used for electric spark ignition. Here, the specific structure of the ignition device 9 is not limited.

[0042] The above-mentioned embodiments mention that the burner 100 can be used in a manual manner or an electric control manner.

[0043] In some embodiments, the burner 100 can be automatically controlled. Specifically, the burner 100 includes a controller 10 for controlling combustion.

[0044] Among them, the controller 10 is electrically connected to the lifter 3 to control the lifting of the lifter 3, so that the automatic lifting of the lifter 3 can be realized. Here, the way the controller 10 controls the lifter 3 can preset a control program, and according to the control program before or during combustion, the lifting operation of the lifter 3 is completed. Or the controller 10 includes a remote communication unit for receiving remote signals to control the lifting of the lifter 3. In this way, the lifting of the lifter 3 can be remotely controlled. On the one hand, the remote control operator can be away from the burner 100, improving safety. On the other hand, remote operation can be used to adjust the lifting of the lifter 3 in real time according to the operator's observation and judgment of the combustion scenario, improving the flexibility and safety of combustion control.

[0045] The burner 100 further includes an ignition device 9 for igniting at each combustion hole 21 respectively, and the controller 10 is electrically connected to the ignition device 9. In this way, when igniting the combustion holes 21, it can be automatically controlled by the controller 10 to complete, reducing the harm to the operator caused by the deflagration at the moment of ignition. Moreover, being far away from the fire source, the operator can also reduce the inhalation of harmful gases, ensuring the health and safety of the operator.

[0046] Here, the way for the controller 10 to control the ignition device 9 can be to preset a control program and complete the startup of the ignition device 9 according to the control program after startup. Or the controller 10 includes a remote communication part for receiving a remote signal to control the switch of the ignition device 9. With remote operation, the operator can flexibly choose when to ignite and turn off the fire according to the on-site situation, and the ignition is safer and more controllable.

[0047] Certainly, the ignition device 9 may not be provided in this application, and in other embodiments, the combustion holes 21 can also be directly manually ignited by the operator. Of course, the life safety of the operator needs to be ensured on-site during manual ignition.

[0048] As Figure 3 shown, by way of example, when combustion detection needs to be performed on a car door: 1. Place the burner 100 outside the car door close to the car door, and adjust the height of the burner 100 through the lifter 3 according to the ground clearance of the whole vehicle; 2. After the burner 100 is placed stably, select the combustion unit 2 according to the width of the car door. If the car door size is large, select the gas pipelines of multiple adjacent combustion units 2, such as 5 combustion holes 21 corresponding to 5 branch pipes 5; if the car door size is small, select the 3 middle branch pipes 5 or other adjacent branch pipes 5 corresponding combustion holes 21, and one combustion unit 2 can be selected; 3. After all procedures are confirmed, finally confirm the stability of the burner 100, and then the tester confirms the height of the outer handle or button position of the tested car door; 4. Open the gas source pipe 4 and the pressure valve 6, and set the flow meter 8 or adjust the air flow through the pressure valve 6; then, set the flow meter 8 according to the time required for the test verification; 5. Perform an ignition operation on the burner 100 through the ignition switch; 6. When the test verification time reaches the specified set time, automatically cut off the delivery of the combustible gas through the flow meter 8, and at the same time control the pressure valve 6 to close it. After the residual gas burns out, the burner 100 can be moved to verify the function of its car door lock. At the same time, by setting the image collector 200, the on-site situation can be surveyed and recorded.
