Description

Technical Field

[0001] This utility model relates to the field of driver's license examinations, and in particular to a suspension rod device for motor vehicle driver's license examinations. Background Technology

[0002] The driving test is a necessary step to obtain a motor vehicle driving qualification. It usually includes two parts: a theory test and a practical test. In the driving test, a parking lever is used to help assess the candidate's parking skills, especially in operations such as reversing into a parking space and parallel parking. However, if the traditional spring-loaded parking lever is hit by the test vehicle during the test, the spring can easily rebound violently when the vehicle reverses, violently hitting the vehicle and people, posing a significant safety hazard.

[0003] A search revealed that the Chinese patent "A Suspension Rod Device for Motor Vehicle Driving Tests" (authorization announcement number CN217718883U) describes a utility model where a bowl-shaped clamp is secured to a horizontal plate on a suspension plate, allowing the suspension rod to hang vertically below the plate. When a driving test vehicle passes by and hits the suspension rod, the rod sways, indicating contact with the vehicle. Because the rod is suspended and the suspension plate is rotatably connected to the suspension mechanism, the rod quickly returns to its original position after the collision. When the driving test vehicle drags the rod, the force is applied to the bowl-shaped clamp, causing it to deform within the C-shaped clamp until it detaches. This prevents damage to the suspension rod device or the driving test vehicle due to violent pulling, improving the safety of the suspension rod. After the rod detaches, it can be re-secured into the C-shaped clamp using the bowl-shaped clamp. This invention enables the boom to return to its original position after a collision and allows it to automatically detach when pulled, ensuring safety during use. The device has a simple overall structure, is easy to use, has low cost, and is reusable.

[0004] Although the above-mentioned method utilizes the rotating connection between the suspension plate and the suspension mechanism, and the suspension rod will quickly return to its original position after a collision, the suspension rod is inserted into the C-shaped slot opened in the suspension plate, and the suspension plate is rotatably connected to the hook through the first universal joint. When the vehicle moves backward or stops after a collision, the suspension rod rotates due to the impact force after being hit by the vehicle, causing the suspension rod to sway back and forth and hit the vehicle body, which affects the stability of the suspension rod when it is hit.

[0005] Therefore, a suspension device for motor vehicle driving tests is proposed to solve the above problems. Utility Model Content

[0006] The purpose of this utility model is to provide a suspension rod device for motor vehicle driving tests in order to solve the above-mentioned problems. It improves the problem that when a vehicle is reversing or stops after a collision, the suspension rod rotates due to the impact force of the vehicle, causing the suspension rod to swing back and forth and hit the vehicle body, which affects the stability of the suspension rod when it is hit.

[0007] This utility model achieves the above-mentioned objective through the following technical solution: a suspension rod device for motor vehicle driving test, comprising: a suspension rod for simulating or testing a driver's ability to respond to traffic signs, lanes, and traffic rules, etc., a funnel shell fixedly connected to the top of the suspension rod, a limiting plate being snapped onto the outer surface of the funnel shell, and an adjusting shell being provided above the limiting plate; a buffer mechanism, the buffer mechanism comprising a buffer cylinder fixedly connected to one side of the adjusting shell, a piston being provided in the inner cavity of the buffer cylinder, a buffer rod being fixedly connected to one side of the piston, the other end of the buffer rod passing through the buffer cylinder and fixedly connected to a first buckle, a steel cable being provided in the inner cavity of the buckle, a second buckle being provided at the other end of the steel cable, and the second buckle being fixedly connected to one side of the limiting plate. By using a buffer cylinder, piston, buffer rod, first retaining ring, steel cable, and second retaining ring, when a vehicle impacts the boom, the movable rod will drive the boom at the bottom of the limiting plate to move diagonally upward. At the same time, the limiting plate will pull the steel cable, which will drive the buffer rod and piston to move slowly to one side of the buffer cylinder's inner cavity. When the vehicle stops, the piston and buffer rod will drive the steel cable and boom to move slowly diagonally downward, thereby buffering the boom when it is subjected to a large impact force and improving the boom's stability during use.

[0008] Preferably, a spring is fixedly connected to one side of the buffer cylinder, and the other end of the spring is fixedly connected to one side of the first buckle. The spring allows the boom to be cushioned by compression when it sways significantly left or right, while simultaneously slowly returning to its upright position.

[0009] Preferably, limit blocks are fixedly connected to both sides of the piston, and the surface of the limit blocks is slidably connected to the inner wall of the buffer cylinder. The limit blocks limit the piston's movement during its motion, ensuring that the piston maintains linear motion.

[0010] Preferably, the funnel shell is made of rubber, and the top diameter of the funnel shell is larger than the bottom diameter. The rubber funnel shell can be deformed by squeezing and then inserted into the interior of the limiting plate for positioning.

[0011] Preferably, a limiting ring is fixedly connected to the top of the funnel shell, and the limiting ring is made of rubber. The limiting ring effectively limits the position of the funnel shell when it is engaged with the inner cavity of the limiting plate, preventing the funnel shell from falling under the limiting plate.

[0012] Preferably, a universal joint is provided at the top of the limiting plate, a movable rod is fixedly connected to the top of the universal joint, a slider is hinged to the top of the movable rod, the surface of the slider is slidably connected to the inner wall of the adjusting shell, and a collar is provided at the inner bottom of the adjusting shell. The universal joint, movable rod, slider, and collar are used to first fix the collar to other fixed objects to secure the overall equipment. When a student vehicle lightly bumps the boom from its inclined surface or other angle, the boom rotates through the universal joint instead of swaying significantly. When the vehicle impacts the boom from the side with a larger force, the boom sways significantly left and right through the movable rod.

[0013] Preferably, both the adjusting shell and the slider have insertion holes on their outer surfaces. The adjusting shell has several insertion holes, and the slider has one insertion hole. A rod is inserted into the inner cavity of each insertion hole. The rod can be inserted into the insertion hole in the adjusting shell and the slider to position the slider.

[0014] The beneficial effects of this utility model are:

[0015] By using a buffer cylinder, piston, buffer rod, first retaining ring, steel cable, and second retaining ring, when a vehicle impacts the boom, the movable rod will drive the boom at the bottom of the limiting plate to move diagonally upward. At the same time, the limiting plate will pull the steel cable, which will drive the buffer rod and piston to move slowly to one side of the buffer cylinder's inner cavity. When the vehicle stops, the piston and buffer rod will drive the steel cable and boom to move slowly diagonally downward, thus buffering the boom when it is subjected to a large impact force, improving the boom's stability during use. This reset method avoids the problem of conventional reset methods where, when the vehicle moves backward or stops after a collision, the boom rotates due to the impact force of the vehicle, causing the boom to sway back and forth and hit the vehicle body, affecting the boom's stability when impacted.

[0016] By using universal joints and movable rods, the boom can only sway left and right and rotate in place, ensuring that it will not sway wildly when subjected to large impact forces, thus improving the stability of the boom during use. Attached Figure Description

[0022] The technical solutions of the present utility model 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 utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] In practical implementation: such as Figure 1-4 As shown, a suspension rod 1 device for motor vehicle driving test includes: a suspension rod 1 for simulating or testing a driver's ability to respond to traffic signs, lanes, and traffic rules, etc., a funnel shell 2 fixedly connected to the top of the suspension rod 1, a limit plate 4 snapped onto the outer surface of the funnel shell 2, and an adjusting shell 8 disposed above the limit plate 4; a buffer mechanism 12, the buffer mechanism 12 including a buffer cylinder 1201 fixedly connected to one side of the adjusting shell 8, a piston 1202 disposed in the inner cavity of the buffer cylinder 1201, and a buffer rod 1203 fixedly connected to one side of the piston 1202, the buffer rod 1203... The other end passes through the buffer cylinder 1201 and is fixedly connected to a first buckle 1204. A steel cable 1205 is provided in the inner cavity of the first buckle 1204. A second buckle 1206 is provided at the other end of the steel cable 1205. The second buckle 1206 is fixedly connected to one side of the limiting plate 4. A spring 1207 is fixedly connected to one side of the buffer cylinder 1201. The other end of the spring 1207 is fixedly connected to one side of the first buckle 1204. Limiting blocks 1208 are fixedly connected to both sides of the piston 1202. The surface of the limiting block 1208 is slidably connected to the inner wall of the buffer cylinder 1201.

[0024] The bottom inner part of the limiting plate 4 has a circular groove. The funnel shell 2 is positioned by engaging with the inner wall of the circular groove. When the driving test vehicle is dragged along the suspension rod 1, a force is applied to the funnel shell 2, causing it to deform within the circular groove until it comes out. This prevents damage to the suspension rod 1 or the driving test vehicle due to violent pulling, thus improving the safety of using the suspension rod 1.

[0025] A rubber sleeve is provided at the bottom of the outer surface of the boom 1 to protect the boom 1 when it is subjected to impact.

[0026] like Figure 1 and Figure 4 As shown, the funnel shell 2 is made of rubber, and the top diameter of the funnel shell 2 is larger than the bottom diameter. A limiting ring 3 is fixedly connected to the top of the funnel shell 2. The limiting ring 3 is made of rubber. A universal joint 5 is provided on the top of the limiting plate 4. A movable rod 6 is fixedly connected to the top of the universal joint 5. A slider 7 is hinged to the top of the movable rod 6. The surface of the slider 7 is slidably connected to the inner wall of the adjusting shell 8. A collar 9 is provided at the bottom of the inner wall of the adjusting shell 8. Insertion holes 10 are provided on the outer surfaces of both the adjusting shell 8 and the slider 7. There are several insertion holes 10 on the outer surface of the adjusting shell 8 and one insertion hole 10 on the outer surface of the slider 7. An insertion rod 11 is inserted into the inner cavity of the insertion hole 10.

[0027] First, insert the rod 11 into the insertion hole 10 in the adjusting shell 8 and the slider 7 to position the slider 7. Then, fix the collar 9 to other fixed objects to secure the entire device. When the trainee's vehicle lightly bumps the boom 1 from the inclined surface or other angles, the boom 1 rotates through the universal joint 5 instead of swaying significantly. When the vehicle hits the boom 1 from the side with a large impact force, the boom 1 sways significantly from side to side through the movable rod 6. The movable rod 6 will drive the boom 1 at the bottom of the limiting plate 4 to move obliquely upward. At the same time, the limiting plate 4 will pull the steel cable 1205. The steel cable 1205 will drive the buffer rod 1203 and the piston 1202 to move slowly to one side of the inner cavity of the buffer cylinder 1201. When the vehicle stops, the piston 1202 and the buffer rod 1203 will drive the steel cable 1205 and the boom 1 to move slowly obliquely downward, thereby buffering the boom 1 when it is subjected to a large impact force and improving the stability of the boom 1 during use.

[0028] In use, the insert rod 11 is first inserted into the insertion hole 10 in the adjusting shell 8 and the slider 7 to position the slider 7. Then, the collar 9 is fixed to other fixed objects to fix the overall equipment. When the trainee vehicle lightly bumps the boom 1 from the inclined surface or other angles, the boom 1 rotates through the universal joint 5 instead of swaying significantly. When the vehicle hits the boom 1 from the side with a large impact force, the boom 1 sways significantly from side to side through the movable rod 6. The movable rod 6 will drive the boom 1 at the bottom of the limiting plate 4 to move obliquely upward. At the same time, the limiting plate 4 will pull the steel cable 1205. The steel cable 1205 will drive the buffer rod 1203 and the piston 1202 to move slowly to one side of the inner cavity of the buffer cylinder 1201. When the vehicle stops, the piston 1202 and the buffer rod 1203 will drive the steel cable 1205 and the boom 1 to move slowly obliquely downward, thereby buffering the boom 1 when it is subjected to a large impact force and improving the stability of the boom 1 during use.

[0029] It should be noted that the universal joint 5 and steel cable 1205 mentioned above are all devices with relatively mature existing technology. The specific models can be selected according to actual needs, and will not be elaborated here.

[0030] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
