Description

Technical Field

[0001] The invention relates to the technical field of automobile driving safety testing, and in particular to a device for simulating automobile tire blowout. Background Art

[0002] The purpose of the method of simulating a tire blowout is to simulate the impact of a sudden tire blowout on the vehicle's handling stability during driving, such as steering failure and braking failure that may occur in the vehicle after a tire blowout.

[0003] At present, the main methods of simulating tire blowout are: installing an air release valve on the rim and using a solenoid valve to deflate the tire. The advantage is that the tire can be recycled, but the disadvantage is that the rim needs to be re-modified for testing vehicles with different wheel diameters; the method of blasting with explosives has the advantage of being small in size and easy to install; the disadvantage is that the installation process has high requirements for the pasting process. For example, if the adhesive strip wrapping the explosive block is not firmly bonded, the energy generated by the explosive will peel the adhesive strip off the sidewall of the tire without any damage to the tire. Summary of the invention

[0004] In view of the defects existing in the prior art, the purpose of the present invention is to provide a device for simulating automobile tire blowout, which can solve the problem that the adhesive strip used to stick the explosive block in the prior art is not reliable, and the energy generated by the explosive will peel the adhesive strip off the side wall of the tire without any damage to the tire.

[0017] The mounting plate is connected to the adapter frame and is used for mounting the blasting mechanism. The mounting plate can rotate relative to the adapter frame and is used for adjusting the blasting direction of the blasting mechanism.

[0018] In some optional solutions, the wheel connecting frame includes:

[0019] A transverse connecting plate, which has two first oblong holes spaced apart in the length direction and is used to be connected to the wheel hub via bolts, and a first bolt hole is provided between the two first oblong holes;

[0020] The L-shaped frame includes a lateral plate and a longitudinal plate which are connected to each other and are perpendicular to each other. Two second oblong holes are arranged on the longitudinal plate at intervals.

The sliding connecting plate is provided with a third oblong hole for connecting to the second bolt hole on the side plate through bolts, and the rotating connecting plate is used to set the mounting plate.

[0023] In some optional solutions, the sliding connection plate is provided with a limiting plate on one side close to the lateral plate for clamping on both sides of the lateral plate.

[0024] In some optional schemes, the blasting mechanism also includes a wireless control device, which is connected to the blasting charge and is used to control the blasting timing of the blasting charge.

[0025] In some optional schemes, an angle sensor is also included, which is arranged on the mounting bracket and is used to detect the rotation angle of the tire and transmit it to the wireless control device.

[0026] Compared with the prior art, the advantages of the present invention are: the present invention installs the blasting mechanism on the wheel hub through the mounting bracket, and when the vehicle is driving under test and reaches the set conditions or the set time, the blasting filler disposed between the bottom of the launch chamber and the puncture is blasted, generating a force to push out the puncture, so that the puncture punctures the side wall of the tire, thereby achieving a driving state simulating a car tire blowout.

DETAILED DESCRIPTION

[0038] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0039] The embodiments of the present invention are further described in detail below with reference to the accompanying drawings.

[0040] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the present invention provides a device for simulating automobile tire blowout, comprising: a mounting bracket 1 and at least one blasting mechanism 3. The mounting bracket 1 is used to be connected to the wheel hub 7; the at least one blasting mechanism 3, each blasting mechanism 3 comprises: a sleeve 31, a puncture 32 and a blasting filler 33, the sleeve 31 is arranged on the mounting bracket 1, and a launch cavity is arranged in the sleeve 31; the puncture 32 is arranged in the launch cavity; the blasting filler 33 is arranged between the bottom of the launch cavity and the puncture 32, and is used to generate a force to push out the puncture 32, so that the puncture 32 punctures the side wall of the tire 2.

[0041] When the device for simulating automobile tire blowout is used, the blasting mechanism 3 is mounted on the wheel hub 7 through the mounting bracket 1. When the vehicle is driving under test and reaches the set condition or the set time, the blasting filler 33 disposed between the bottom of the launch chamber and the puncture 32 is blasted, generating a force to push out the puncture 32, so that the puncture 32 punctures the side wall of the tire 2, achieving the driving state of simulating automobile blowout. This solves the problem in the prior art that when using explosives for blasting, the adhesive strip wrapping the explosive block is not firmly bonded, and the energy generated by the explosives will peel the adhesive strip off the tire side wall without any damage to the tire.

[0042] In addition, the blasting filler 33 is explosive, which can generate a force to push the puncture 32 out of the launch cavity provided in the casing 31 when it explodes, thereby puncturing the side wall of the tire 2. The diameter of the puncture 32 near the end of the blasting filler 33 is slightly smaller than the diameter of the launch cavity in the casing 31, which is more conducive to the blasting filler 33 exploding between the bottom of the launch cavity and the puncture 32, so that more force is applied to the puncture 32, and the puncture 32 is not constrained by the launch cavity when it is ejected. The puncture 32 is away from the end of the blasting filler 33, that is, the end near the side wall of the tire 2, and has a wedge-shaped surface, and extends obliquely toward one side of the wheel hub, which is more conducive to the puncture 32 puncturing the side wall of the tire 2.

[0043] In this example, the device includes three blasting mechanisms 3 arranged side by side, which can serve as backup for each other when in use, thereby increasing the redundancy performance of the device.

[0044] like Figure 2 As shown, in some optional embodiments, the sleeve 31 also includes a reaction force chamber, which is separated from the launch chamber by a partition 311 and contains a reaction force filler 34 for blasting to generate a reaction force to offset the force generated by the blasting filler 33.

[0045] In this embodiment, the reaction force chamber is separated from the firing chamber by a partition 311, and a reaction force filler 34 is filled in the reaction force chamber. The equal reverse force generated by the reaction force filler 34 is used to offset the force of the blasting filler 33 pushing the puncture 32, so as to achieve force balance. The sleeve 31 will not be displaced relative to the mounting bracket 1, nor will it have a large impact on the mounting bracket 1. Therefore, when designing the mounting bracket 1, it is not necessary to design the strength to be very high to save costs and avoid high structural strength, resulting in heavy weight, which affects the stability of the vehicle after the explosion.

[0046] like Figure 3 and Figure 4 As shown, in some optional embodiments, the blasting mechanism 3 further includes a pitch bracket 35 , which is disposed on the mounting bracket 1 , a ball seat is disposed inside the pitch bracket 35 , and a hinged ball 36 matching the ball seat is sleeved outside the sleeve 31 .

[0047] In this embodiment, a ball seat is provided in the pitch bracket 35, and a hinge ball 36 matching the ball seat is provided on the outer side of the sleeve 31. The sleeve 31 is installed in the ball seat of the pitch bracket 35 through the hinge ball 36, so that the direction of the sleeve 31 can be adjusted, and thus the blasting direction of the entire blasting mechanism 3 can be adjusted, which is convenient for adjusting the ejection direction of the puncture 32 after blasting, and is conducive to adjusting the radial direction position of the side wall of the punctured tire 2. Figure 7 As shown, the sleeve 31 is installed in the ball seat of the pitch bracket 35 through the hinge ball 36, so that the orientation angle A of the sleeve 31 can be adjusted.

[0048] like Figure 5 and Figure 6 As shown, in some optional embodiments, the mounting bracket 1 includes: a wheel connecting frame 11, an adapter frame 12 and a mounting plate 13, the wheel connecting frame 11 is used to connect with the wheel hub 7, and the position relative to the radial direction of the wheel hub 7 can be adjusted; the adapter frame 12 is connected to the wheel connecting frame 11, and the distance away from or close to the side wall of the tire 2 can be adjusted; the mounting plate 13 is connected to the adapter frame 12, used to install the blasting mechanism 3, and can rotate relative to the adapter frame 12, and is used to adjust the blasting direction of the blasting mechanism 3.

[0049] In this embodiment, the wheel connecting frame 11, the adapter frame 12 and the mounting plate 13 are connected in sequence to install the mounting bracket 1 of the blasting mechanism 3. The position of the blasting mechanism 3 in the radial direction of the tire 2 can be adjusted to puncture the sidewalls of the tire 2 at different radial positions. The distance of the blasting mechanism 3 away from or close to the sidewall of the tire 2 can be adjusted to accommodate tires with different wall thicknesses. The wheel connecting frame 11 is connected to the wheel hub 7, and its position relative to the radial direction of the wheel hub 7 can be adjusted, thereby driving the position of the blasting mechanism 3 in the radial direction of the tire 2; the adapter frame 12 is connected to the wheel connecting frame 11, and its distance away from or close to the sidewall of the tire 2 can be adjusted, thereby driving the entire blasting mechanism 3 away from or close to the sidewall of the tire 2. Figure 8 As shown, the mounting plate 13 is connected to the adapter frame 12 and can rotate relative to the adapter frame 12 to adjust the blasting direction of the blasting mechanism 3 and the angle B between the blasting mechanism 3 and the axial direction of the wheel hub 7 .

[0050] The blasting mechanism 3 drives the elevation bracket 35 to rotate to the desired angle and lock it through the angle locking knob 14 , and cooperates with the mounting plate 13 to connect with the adapter frame 12 , and can rotate the angle, so as to adjust the direction of the blasting mechanism 3 .

[0051] In some optional embodiments, the wheel connecting frame 11 includes: a transverse connecting plate 111 and an L-shaped frame 112, the transverse connecting plate 111 is provided with two first oblong holes at intervals in the length direction for connecting to the wheel hub 7 by bolts, and a first bolt hole is provided between the two first oblong holes; the L-shaped frame 112 includes a lateral plate and a longitudinal plate which are connected to each other and are perpendicular, and two second oblong holes are provided at intervals on the longitudinal plate, the second oblong hole close to one side of the lateral plate is used to connect to the transverse connecting plate 111 by bolts, and the other second oblong hole is used to connect to the wheel hub 7 by bolts, and a second bolt hole is provided on the lateral plate for connecting to the adapter frame 12 by bolts.

[0052] In this embodiment, two first oblong holes are provided at intervals in the length direction of the transverse connecting plate 111, which are used to connect with the wheel hub 7 by bolts, and can match wheel hubs of different diameters. Two second oblong holes are provided at intervals on the longitudinal plate, and the second oblong hole on the side away from the lateral plate is used to connect with the wheel hub 7 by bolts, and can match wheel hubs of different angles and wheels of different wheel diameters. The lateral plate extends to the side away from the wheel hub 7, which can ensure that the adapter frame 12 is arranged on the outside of the wheel hub 7, which is convenient for installing the blasting mechanism 3.

[0053] In some optional embodiments, a counterweight 5 is provided at one end of the longitudinal plate away from the lateral plate.

[0054] In this embodiment, since an adapter frame 12 is installed on the longitudinal plate, a mounting plate 13 is provided on the adapter frame 12, and a blasting mechanism 3 is installed on the mounting plate, the vehicle may become unstable during operation. Therefore, a counterweight block 5 is provided at the end of the longitudinal plate away from the lateral plate to ensure relative stability of the vehicle during operation and avoid affecting the test results.

[0055] In some optional embodiments, the adapter frame 12 is a Z-shaped frame, including a sliding connecting plate 121, a support plate 122 and a rotating connecting plate 123 connected in sequence, and the sliding connecting plate 121 and the rotating connecting plate 123 are perpendicular to the support plate 122 and are located on both sides of the support plate 122. A third oblong hole is provided on the sliding connecting plate 121 for connecting to the second bolt hole on the side plate through bolts, and the rotating connecting plate 123 is used to set the mounting plate 13.

[0056] In this embodiment, the rotating connecting plate 123 and the sliding connecting plate 121 are parallel to each other and are perpendicular to the supporting plate 122. Since the mounting plate 13 is provided on the rotating connecting plate 123 for mounting the blasting mechanism 3, and the third oblong hole is provided on the sliding connecting plate 121 for connecting with the second bolt hole on the side plate through bolts, the relative position of the sliding connecting plate 121 and the side plate can be adjusted to adjust the spacing distance between the blasting mechanism 3 and the tire 2.

[0057] In some optional embodiments, a side of the sliding connection plate 121 close to the lateral plate is provided with a limiting plate 125 for clamping on both sides of the lateral plate.

[0058] In this embodiment, a limiting plate is provided on the sliding connection plate 121 to limit the position of the sliding connection plate 121 and prevent the sliding connection plate 121 from rotating when the relative position between the sliding connection plate 121 and the lateral plate is adjusted.

[0059] In addition, a reinforcing plate 124 is provided between the sliding connection plate 121 and the supporting plate 122 to improve the strength of the adapter frame 12 .

[0060] In some optional embodiments, the blasting mechanism 3 further includes a wireless control device 4 , which is connected to the blasting charge 33 and is used to control the blasting timing of the blasting charge 33 .

[0061] In this embodiment, the blasting timing of the blasting filler 33 is remotely controlled by the wireless control device 4. It is possible to judge whether the driving state of the vehicle meets the preset requirements under remote conditions. For example, when the preset required speed is reached, the blasting filler 33 is remotely controlled to explode so that the explosion generates a force to push out the puncture 32, so that the puncture 32 punctures the side wall of the tire 2.

[0062] like Fig. 9 As shown, in some optional embodiments, the device further includes an angle sensor 6 , which is disposed on the mounting bracket 1 and is used to detect the rotation angle of the tire 2 and transmit the angle to the wireless control device 4 .

[0063] In this embodiment, the rotation angle of the tire 2 is detected by the angle sensor 6. When the tire 2 rotates to the angle C range and the vehicle speed reaches the set speed, the wireless control device 4 is triggered, and the puncture 32 penetrates the tire sidewall close to the ground along the D direction to achieve the purpose of rapid deflation. The test is now completed. Angle C is the angle between the tire radial line where the blasting mechanism 3 is located and the vertical line. Angle C is generally set to be less than 45 degrees. At this time, the blasting mechanism 3 is close to the ground, which can avoid damage to other important components such as the engine in the vehicle during the blasting.

[0064] In this example, the wireless control device 4 is connected to the ignition device 42 that passes through the reaction force filler 34, the partition 311 and the blasting filler 33 through the wire 41.

[0065] In summary, the present invention installs the blasting mechanism 3 on the wheel hub 7 by means of the mounting bracket 1. When the vehicle is driving under test and reaches the set conditions or the set time, the blasting filler 33 disposed between the bottom of the launch chamber and the puncture 32 is blasted, generating a force to push out the puncture 32, so that the puncture 32 punctures the side wall of the tire 2, thereby achieving a driving state simulating a tire blowout of a car. This solves the problem in the prior art that when explosives are used for blasting, the adhesive strips wrapping the explosive blocks are not firmly bonded, and the energy generated by the explosives will peel off the adhesive strips from the side wall of the tire without any damage to the tire.

[0066] The reaction force filler 34 is filled in the reaction force cavity, and the equal reverse force generated by the reaction force filler 34 is used to offset the force of the blasting filler 33 pushing the puncture 32, so as to achieve force balance, and the sleeve 31 will not be displaced relative to the mounting bracket 1, nor will it have a large impact on the mounting bracket 1. Therefore, when designing the mounting bracket 1, it is not necessary to design the strength to be very high to save costs, and to avoid high structural strength, resulting in heavy weight, and affecting the stability of the vehicle after the explosion.

[0067] A ball seat is arranged in the pitch bracket 35, and a hinge ball 36 matching the ball seat is arranged on the outer side of the sleeve 31. The sleeve 31 is installed in the ball seat of the pitch bracket 35 through the hinge ball 36 to adjust the ejection direction of the puncture 32 after the explosion, which is conducive to adjusting the radial position of the side wall of the punctured tire 2. The wheel connecting frame 11 is connected to the wheel hub 7, and can adjust the radial position relative to the wheel hub 7 to drive the blasting mechanism 3 in the radial direction of the tire 2; the adapter frame 12 is connected to the wheel connecting frame 11, and can adjust the distance away from or close to the side wall of the tire 2 to drive the entire blasting mechanism 3 away from or close to the side wall of the tire 2, so that the present solution can adapt to tires of different diameters and different wall thicknesses.
