Description

Technical Field

[0001] The present invention relates to the field of auxiliary processing equipment for faulty wheels. Background Art

[0002] At present, when people face problems such as flat tires and air leakage, they usually first move the vehicle to a safe place and then replace the spare tire. This will cause the following problems: First, after the wheel fails, it is very difficult to move the vehicle. Forcibly starting the vehicle will damage the wheel hub, and in severe cases, it may even cause traffic accidents due to difficult control. Second, with the continuous development of automobiles, anti-theft bolts are more and more widely used in vehicles. Therefore, once the special anti-theft nuts are lost, the vehicle owner must spend a long time waiting for a tow truck when facing a wheel failure. Third, when the vehicle owner replaces the spare tire by himself, it usually takes a long operation time. Therefore, it also greatly increases the risk of traffic jams.

[0003] In response to this, the applicant announced a Chinese invention patent named "An Emergency Self-rescue Vehicle for Faulty Wheels" with the application number "201710240675.7" on April 13, 2017. However, after people actually used it, it was found that due to a certain height difference between the vehicle body and the ground, it was extremely easy to have problems such as the small vehicle slipping and caving in during the process of the faulty wheel entering the vehicle body only guided by the guide rail. As a result, the process of the faulty wheel entering the vehicle body became extremely inconvenient, which had a great impact on the actual use effect of this case. Summary of the Invention

[0004] In view of the above problems, the present invention provides a self-rescuer for faulty tires with a delicate structure, convenient use, short operation time, and the faulty wheel can smoothly and quickly enter the vehicle body during use.

[0005] The technical solution of the present invention is as follows: It includes a vehicle body. It is characterized in that the self-rescuer for faulty tires further includes a guide frame. The top of the guide frame is detachably connected to one side of the vehicle body and is arranged along the length direction of the vehicle body. A benchmark is provided on the side of the lower part of the guide frame away from the vehicle body. The benchmark is fixedly connected to the guide frame and is arranged perpendicular to the length direction of the vehicle body. The angle between the bottom of the guide frame and the horizontal plane is 60-90°.

[0006] The length of the benchmark is the same as the width of the faulty wheel.

[0007] The guide frame includes a pair of guide rods and at least one fixing plate. The two guide rods are parallel to each other. The two sides of the fixing plate are respectively fixedly connected to the two guide rods. The guide rods are divided into an insertion section, a guiding section, and a abutting section;

[0008] The vehicle body is provided with insertion holes adapted to the guide rods. The insertion section is detachably connected in the insertion holes and forms an angle of 0 - 5° with the horizontal plane. The guiding section and the insertion section are integrally connected by an upper arc-shaped rod. The guiding section and the insertion section form an angle of 5 - 20°. The abutting section and the guiding section are integrally connected by a lower arc-shaped rod. The abutting section forms an angle of 60 - 90° with the horizontal plane.

[0009] The distance between the guide rods is L, the diameter of the guide rods is D. The rim of the faulty wheel has a bead seat for accommodating the tire. The width of the bead seat is W, and the wall thickness of the tire is H, where L + 2D ≤ W - 4H.

[0010] The vehicle body is also fixedly connected with a vertically arranged blocking plate. The blocking plate is located on the side of the guiding plate away from the guide frame, and the blocking plate is fixedly connected to the vehicle body through an elastic connecting plate.

[0011] On both sides of the clamping block in the faulty tire self-rescuer, there are also guiding plates. The guiding plates are fixedly connected to the vehicle body. The guiding plates are arranged along the length direction of the vehicle body, and the distance from the center line of the vehicle body gradually increases from the side where the clamping block is located.

[0012] The bottom of the vehicle body is also fixedly connected with a hanging basket for supporting the faulty wheel. On the side of the hanging basket in the advancing direction of the vehicle body, there is also a downward baffle inclined upward.

[0013] In the present invention, since the guide frame continuously receives the acting force of the faulty wheel, and the angle between the bottom end of the guide frame and the ground is relatively large, therefore, it will continuously remain fixed to the ground, that is, the vehicle body is kept stable, effectively avoiding problems such as the vehicle body slipping and moving around, which may cause difficulties in getting the faulty wheel into the vehicle body, thus greatly improving the use effect of this case. After the faulty wheel completely enters the vehicle body and the locking block acts to lock it, the guide frame can be removed, thus avoiding its influence on the subsequent driving of the vehicle. In addition, since the faulty wheel will first cross a benchmark with a lower height and then enter the vehicle body with a higher height, therefore, through the transition of the guide frame, the problem of the vehicle body rubbing against the car bumper can be effectively avoided.

[0014] This case as a whole has the advantages of delicate structure, convenient use and short operation time. By adding a guide frame and a benchmark, the problem that the vehicle body is prone to slip when the faulty wheel enters the vehicle body is effectively overcome. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] As shown in the present invention Figures 1-6 shown, it includes a vehicle body 1, a traveling assembly 2 and a clamping assembly 3. The traveling assembly 2 includes a plurality of traveling wheels connected to the bottom of the vehicle body, so that the vehicle body 1 can move freely on the ground;

[0026] The clamping assembly 3 includes a linear drive assembly and a pair of clamping blocks 32. The pair of clamping blocks 32 are arranged oppositely and are slidably connected to both sides of the vehicle body 1. The linear drive assembly is connected between the vehicle body 1 and the clamping blocks 32. The linear drive assembly is used to drive the two clamping blocks 32 to perform synchronous linear reciprocating motion, so as to clamp both sides of the faulty wheel 5; in this way, when the faulty wheel enters the vehicle body, the drive assembly can be activated to drive the two clamping blocks to tighten inward, so as to clamp the faulty wheel efficiently and stably from both sides; conversely, the two clamping blocks can also be driven by the linear drive assembly to open outward, so as to release the clamping of the faulty wheel;

[0027] The linear drive mechanism includes a driving shaft 311, a pair of drive chains 312 and a pair of driven shafts 313. The driving shaft 311 is hinged in the vehicle body 1. The driven shafts 313 are pivotally connected to one end of the clamping block 32 away from the center of the vehicle body 1 and are threadedly connected to the clamping block 32. The pair of drive chains 312 are annular and are respectively wound between the two ends of the driving shaft 311 and the two driven shafts 313. In use, a hexagonal groove can be opened at the end of the driving shaft, so that the driving shaft can be driven to rotate manually through components such as a wrench, thereby driving the two driven shafts to rotate synchronously, and finally driving the two clamping blocks to perform synchronous linear reciprocating motion;

[0028] Thus, under the action of the clamping assembly, the faulty wheel can finally be concentric with the vehicle body in height after entering the vehicle body, so as to ensure the stability between the faulty wheel and the vehicle body during subsequent vehicle driving.

[0029] The faulty tire self-rescuer further includes a guide frame 4. The top of the guide frame 4 is detachably connected to one side of the vehicle body 1 and is arranged along the length direction of the vehicle body 1. A benchmark 40 is provided on the side of the lower part of the guide frame 4 away from the vehicle body. The benchmark 40 is fixedly connected to the guide frame 4 and is arranged perpendicular to the length direction of the vehicle body 1. The angle between the bottom of the guide frame 4 and the horizontal plane is 60-90°. In this way, when the faulty wheel drives in, it will first press on the benchmark, and as the vehicle moves forward, it will cross the benchmark (since the height of the benchmark is relatively low, the faulty wheel can cross the benchmark quickly and conveniently), so that the bottom of the guide frame abuts against the ground under the action of the faulty wheel. After that, by controlling the vehicle to continue moving forward, the faulty wheel can gradually enter the vehicle body. During this process, since the guide frame is continuously affected by the force of the faulty wheel, and the angle between the bottom end of the guide frame and the bottom surface is relatively large, it will continuously remain fixed to the ground, that is, the vehicle body remains stable, effectively avoiding problems such as the vehicle slipping and moving around, which makes it difficult for the faulty wheel to enter the vehicle body, and greatly improving the use effect of this case. After the faulty wheel completely enters the vehicle body and the locking block acts to lock it, the guide frame can be removed to avoid affecting the subsequent driving of the vehicle.

[0030] In addition, since the faulty wheel will first cross a benchmark with a relatively low height and then enter the vehicle body with a relatively high height, through the transition of the guide frame, the problem of the vehicle body rubbing against the car bumper can be effectively avoided.

[0031] This case has the advantages of delicate structure, convenient use and short operation time as a whole. By adding a guide frame and a benchmark, the problem that the vehicle body is prone to slipping when the faulty wheel enters the vehicle body is effectively overcome.

[0032] The length of the benchmark 40 is consistent with the width of the faulty wheel. Therefore, when arranging the self-rescuer, the benchmark can be used to align the two outer sides of the rim of the faulty wheel, ensuring that the faulty wheel can directly enter the vehicle body, avoiding large deviations of the faulty wheel before entering the vehicle body, improving the efficiency of subsequent "centering", and having the advantages of good alignment effect and good use effect.

[0033] The guiding frame 4 includes a pair of guiding rods 41 and at least one fixing plate 42. The two guiding rods 41 are parallel to each other. The two sides of the fixing plate 42 are respectively fixedly connected to the two guiding rods 41. The guiding rods 41 are divided into an insertion section 411, a guiding section 412 and an abutting section 413.

[0034] The vehicle body 1 is provided with insertion holes adapted to the guiding rods 41. The insertion section 411 is detachably connected in the insertion holes and forms an angle of 0-5° with the horizontal plane. The guiding section 412 and the insertion section 411 are integrally connected by an upper arc-shaped rod. The guiding section 412 and the insertion section 411 form an angle of 5-20°. The abutting section 413 and the guiding section 412 are integrally connected by a lower arc-shaped rod. The abutting section 413 forms an angle of 60-90° with the horizontal plane. In this way, the guiding frame has the following advantages:

[0035] First, through the abutting section with a relatively large angle with the ground, after the faulty wheel crosses the benchmark, the component force of the gravity of the faulty wheel can be effectively used to press the guiding frame, so that the guiding frame and the vehicle body are kept stable, avoiding the problem that the faulty wheel cannot drive into the vehicle body due to the movement or sliding of the guiding frame or the vehicle body.

[0036] Second, through the guiding section with a relatively small angle with the ground, after the faulty wheel crosses the benchmark, it can drive into the vehicle body conveniently and efficiently; during actual operation, the driver of the vehicle can first step on the accelerator to make the faulty wheel cross the benchmark, and then release the accelerator to make the faulty wheel slide into the vehicle body naturally. Through the relaxation and transition of the guiding section, the problem that the faulty wheel rushes out of the vehicle body due to the driver stepping on the accelerator too much and too hard when crossing one side of the vehicle body without a benchmark is effectively avoided.

[0037] Third, since the angle between the abutting section and the guiding section is relatively large and the angle between the guiding section and the insertion section is relatively small, the faulty wheel can first climb onto and cross the benchmark and then enter the vehicle body, thus effectively avoiding the problem of the vehicle body rubbing against the automobile bumper, especially the front bumper.

[0038] Such as Figure 6As shown, the distance between the guide rods is L, and the diameter of the guide rods is D (the user can select a guide frame with a suitable specification according to the width of the vehicle tire, so as to select a fault tire self-rescuer with a suitable specification). The rim of the faulty wheel has a bead seat for accommodating the tire, the width of the bead seat is W, and the wall thickness of the tire is H, and L + 2D ≤ W - 4H. Thus, it is ensured that after the faulty wheel crosses the benchmark, a pair of guide rods will be within the bead seat, so that the faulty wheel can maintain high stability when traveling on the guide frame. At the same time, before the faulty wheel enters the vehicle body, it can be preliminarily "centered".

[0039] A vertically arranged baffle 6 is also fixedly connected in the vehicle body 1. The baffle is located on the side of the guide plate away from the guide frame, and the baffle is fixedly connected to the vehicle body through an elastic connecting plate (which can be made of elastic materials such as spring steel). Thus, it can effectively avoid the problem that the faulty wheel drives out of the vehicle body due to excessive forward movement when it enters; at the same time, even when there is a problem that the faulty wheel travels a little excessively, it can be buffered first and then pulled back under the action of the elastic connecting plate, so that the faulty wheel returns to the vehicle body again.

[0040] Guide plates 5 are also provided on both sides of the clamping block in the fault tire self-rescuer. The guide plates 5 are fixedly connected to the vehicle body 1. The guide plates are arranged along the length direction of the vehicle body, and the distance from the center line of the vehicle body gradually increases from the side where the clamping block is located.

[0041] In this way, on the one hand, the positions of both ends of the guide plate can be set according to the rim size adapted to the specification of the fault tire self-rescuer during factory production. Thus, after the faulty wheel enters the vehicle body, it can be guided by a pair of guide plates, and finally the center of the faulty wheel is kept consistent with the center of the vehicle body, playing a good role in further "centering".

[0042] On the other hand, since there are a total of four guide plates located on both sides of the two clamping blocks, there will be no obstruction or blockage above the clamping block, leaving space for the structure and movement of the vehicle's suspension and shock absorption, and avoiding the problem of damaging the vehicle suspension due to movement interference.

[0043] A hanging basket 7 for supporting the faulty wheel is also fixedly connected to the bottom of the vehicle body 1. An inclined upward lower baffle 70 is provided on one side of the hanging basket 7 in the advancing direction of the vehicle body. Thus, when the vehicle passes over a speed bump or an uneven road surface, the lower baffle will directly contact the speed bump or the road surface protrusion, so as to effectively protect the faulty tire through the transition and protection of the lower baffle, and avoid damage to the hanging basket and the faulty wheel.

[0044] To sum up, first, through the action of the benchmark, a pair of guide rods, and the blocking plate, the purpose of ensuring that the faulty wheel can smoothly enter the vehicle body can be finally achieved, avoiding the problems that the faulty wheel cannot enter or rush out of the vehicle body, with excellent use effects and good market promotion significance. Second, during the process of the faulty wheel entering the vehicle body, it will be initially centered under the action of a pair of guide rods, further centered under the action of the guide plate, and finally completely centered under the action of the clamping block. Eventually, after the faulty wheel enters the vehicle body, it will finally be concentric with the vehicle body at the same height to ensure the stability between the faulty wheel and the vehicle body during the subsequent vehicle driving.
