Description

Technical Field

[0001] The utility model relates to the field of vehicle tools, and more particularly to a device for safely and quickly placing a vehicle backstop. Background Art

[0002] With the rapid development of society, the number of vehicles is constantly increasing, and the demand for vehicle safety is becoming increasingly higher. Large vehicles, in particular, require the use of a backstop after parking. Backstops, also known as wheel chocks, stoppers, and vehicle blockers, can prevent accidental rolling and collisions after parking, and are the best way to limit the parking position of vehicles.

[0003] Vehicle backstops are usually manually placed by parking lot staff after the vehicle is completely parked. They are generally made of rubber or wood and are quite heavy. Staff typically push and drag the backstops to the front and rear of the tires, causing significant wear and tear on the backstops during use. This results in the backstops being replaced too quickly, increasing operating costs. The space near vehicle tires is small and contains numerous metal structures, creating the possibility of accidental injury when placing the backstops. If a large number of vehicles are entering and exiting, staff will need to constantly move the backstops, placing an excessive burden on their bodies and potentially affecting their health. Utility Model Content

[0004] The purpose of the utility model is to provide a vehicle backstop safe and quick placement device to solve the problem that the vehicle backstop is inconvenient to place and cannot be quickly moved and placed.

[0028] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments. It should be noted that, unless there is a conflict, the embodiments and features in the embodiments of the present application can be combined with each other.

[0029] The following detailed descriptions are all exemplary descriptions and are intended to provide further details of the present invention. Unless otherwise specified, all technical terms used in this utility model have the same meanings as those commonly understood by those skilled in the art to which this application belongs. The terms used in this utility model are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present utility model.

[0030] like Figure 1 and Figure 2As shown, a vehicle backstop safety and quick placement device includes:

[0031] Handrail 1, two-way telescopic rod 2, first bracket 3, second bracket 4, moving wheel 5 and two vehicle backstops 9;

[0032] The first end of the handrail rod 1 is a handle 11, and the second end is vertically connected to the middle part of the two-way telescopic rod 2. The two-way telescopic rod 2 is horizontally arranged. The first end of the two-way telescopic rod 2 is vertically connected to the first end of the first bracket 3, and the second end of the two-way telescopic rod 2 is vertically connected to the first end of the second bracket 4. The second end of the first bracket 3 and the second end of the second bracket 4 are respectively connected to a vehicle backstop 9. The vehicle backstops 9 are arranged opposite to each other, and a moving wheel 5 is also provided at the bottom of the two-way telescopic rod 2.

[0033] Specifically, a grip-friendly handle 11 is located at the first end of the handlebar 1, making it easy for the operator to grasp and push or pull the entire device. The second end of the handlebar 1 is vertically connected to the middle of the two-way telescopic rod 2, providing stable support and convenient operation. The two-way telescopic rod 2 is arranged horizontally, with its first end vertically connected to the first end of the first bracket 3 and its second end vertically connected to the first end of the second bracket 4. This allows the two-way telescopic rod 2 to extend and retract in two vertical directions to accommodate vehicle tires of different sizes. The first bracket 3 and the second bracket 4 are connected to each end of the two-way telescopic rod 2 and located below the two-way telescopic rod 2, respectively, to support and secure the vehicle backstop 9. A movable wheel 5 is located at the bottom of the two-way telescopic rod 2, allowing the entire device to be flexibly moved, facilitating quick positioning and placement of the vehicle backstop 9 in a parking area. The vehicle backstop 9 is connected to the second end of the first bracket 3 and the second end of the second bracket 4, respectively. The two backstops are arranged opposite each other to provide a backstop at the front and rear ends of the vehicle tires.

[0034] The handrail 1 can be realized by a tubular structure, and the diameter and length are designed according to ergonomics to meet the gripping needs of most operators. The bidirectional telescopic rod 2 is composed of two nested tubular components, the outer tube is a transverse sleeve 21, and the inner tube is a slide bar 22 that can slide in the axial direction. The slide bar 22 is provided with a fixing screw and a fixing nut 24, and the extension length of the slide bar 22 is locked by tightening the fixing nut 24. The first bracket 3 and the second bracket 4 are designed to be a telescopic structure. It can be adjusted according to the actual width of the vehicle tire to ensure that the backstop can fit tightly to the tire. The moving wheel 5 includes a rotating wheel and a fixed bracket. The rotating wheel is provided with a braking device so that the device can be stably fixed in the desired position when the vehicle backstop 9 is placed. The vehicle backstop 9 is made of lightweight and high-strength material, and its shape is designed to fit closely with the contour of the tire to provide an effective backstop.

[0035] Through the above-mentioned implementation mode, the device can safely and quickly place the vehicle backstop 9, reducing the labor intensity of the staff, improving the safety and efficiency of vehicle parking, and reducing the wear rate and operating cost of the backstop.

[0036] As a preferred example, the bidirectional telescopic rod 2 includes a transverse sleeve 21 and a sliding rod 22 sleeved on both ends of the transverse sleeve 21. Axial grooves 23 are respectively opened at both ends of the transverse sleeve 21. The two sliding rods 22 are respectively provided with fixing screws, which are slidably set in the axial grooves 23. A fixing nut 24 is provided on the fixing screw. When the sliding rod 22 is extended to the required length, the fixing nut 24 is tightened to fix the position of the sliding rod 22.

[0037] Specifically, the bidirectional telescopic rod 2 consists of a transverse sleeve 21 and two slide rods 22 that are sleeved on both ends of the transverse sleeve 21. The slide rods 22 can slide axially within the transverse sleeve 21 to achieve the function of bidirectional telescopic extension. Axial grooves 23 are respectively provided at both ends of the transverse sleeve 21. The grooves are designed to accommodate fixing screws to ensure the stability and guidance of the slide rods 22 during the telescopic process. Each slide rod 22 is provided with at least one fixing screw, which is arranged along the length of the slide rod 22 and can slide within the axial groove 23 to adjust the extension length of the slide rod 22. The fixing screw is provided with a fixing nut 24, which is used to tighten the slide rod 22 after the slide rod 22 is adjusted to the desired length to fix the position of the slide rod 22 and prevent the slide rod 22 from accidentally retracting or extending during use.

[0038] The transverse sleeve 21 is made of high-strength material to withstand the axial force generated by the bidirectional telescopic rod 2 during operation. The sliding rod 22 and the transverse sleeve 21 are precisely matched to ensure smooth sliding without obvious gaps, thereby improving the stability and service life of the telescopic rod. The design of the axial groove 23 takes into account the size and shape of the fixing screw to ensure that the fixing screw can slide stably in the groove without being blocked. The fixing screw and the fixing nut 24 are matched with standard threads. The operator can quickly adjust the length of the sliding rod 22 as needed and lock the position of the sliding rod 22 by tightening the fixing nut 24. In actual use, the operator can adjust the extension length of the sliding rod 22 by rotating the fixing nut 24 according to the actual size of the vehicle tire until the backstop on the first bracket 3 and the second bracket 4 can adapt to the width of the tire, and then tighten the fixing nut 24 to fix the sliding rod 22 to ensure that the backstop is stably placed.

[0039] Through the above embodiment, the bidirectional telescopic rod 2 of the device can flexibly adjust the length to adapt to vehicle tires of different widths, thereby achieving fast and accurate placement of the vehicle backstop 9, thereby improving the convenience of operation and the applicability of the device.

[0040] As a preferred example, the first bracket 3 and the second bracket 4 are detachably connected to the vehicle backstop 9 via a fixing card mechanism 8 .

[0041] Specifically, the fixing mechanism 8 can consist of a base, a clamping arm, and a locking mechanism. The base is designed to be fixed or connected to the connecting surface of the first bracket 3 or the second bracket 4. The clamping arm extends from one or both sides of the base to directly contact and clamp the side of the vehicle backstop 9. The locking mechanism is provided on the base to lock or release the clamping arm, enabling quick installation and removal of the vehicle backstop 9. The clamping arm has an adjustable width to accommodate vehicle backstops 9 of different sizes. The inner side of the clamping arm is provided with a series of anti-slip bumps or textures to increase the coefficient of friction with the vehicle backstop 9 and ensure the stability of the backstop during placement. The locking mechanism of the fixing mechanism 8 can be a bolt, nut, snap, spring clamp, or other type of quick locking / release device. This mechanism allows the operator to secure or release the vehicle backstop 9 with simple manual operation, improving work efficiency. The connection between the base and the first bracket 3 or the second bracket 4 can be welded, bolted, embedded, or other mechanical connection methods to ensure the stability and reliability of the fixing mechanism 8. The various components of the fixing card mechanism 8 are made of high-strength, wear-resistant materials, such as aluminum alloy, stainless steel or engineering plastics, so as to adapt to the requirements of outdoor environment and long-term use.

[0042] In one embodiment, the clamping arm can automatically clamp the backstop. The locking mechanism adopts a spring-loaded snap design. The operator only needs to press the snap to release the clamping arm, thereby quickly replacing the vehicle backstop 9. The connection between the base and the bracket adopts an embedded design. A part of the base is embedded in the groove of the bracket and fixed by bolts, which improves the stability of the overall structure. Through the above embodiment, the fixed card mechanism 8 structure of the present device not only provides a fast and reliable vehicle backstop 9 installation and removal function, but also meets the needs of different usage scenarios through its design flexibility and durability.

[0043] As a preferred example, the first end of the bidirectional telescopic rod 2 is connected to the first end of the first bracket 3 through the first vertical rod 6, and the second end of the bidirectional telescopic rod 2 is connected to the first end of the second bracket 4 through the second vertical rod 7. The first bracket 3 and the second bracket 4 are located below the bidirectional telescopic rod 2.

[0044] Specifically, the first end of the bidirectional telescopic rod 2 is connected to the first end of the first bracket 3 via a first vertical rod 6, and the second end of the bidirectional telescopic rod 2 is connected to the first end of the second bracket 4 via a second vertical rod 7. The first and second vertical rods 6 and 7 are designed to ensure a stable connection between the bidirectional telescopic rod 2 and the two brackets and provide the necessary support. The height of the first and second brackets 3 and 4 is reduced to facilitate the placement of the vehicle backstop 9. The first and second vertical rods 6 and 7 can be rigidly connected to the bidirectional telescopic rod 2, for example, by welding, bolting, or riveting. Furthermore, the vertical rods can also be rigidly connected to the brackets to ensure the stability and durability of the overall structure. The first and second brackets 3 and 4 are located below the bidirectional telescopic rod 2. This layout allows the backstop to stably support the vehicle tire during placement, preventing the vehicle from sliding or slipping, while also facilitating the operator's ability to observe and adjust the backstop's position from below. The length, cross-sectional shape, and material selection of the first and second vertical rods 6 and 7 are optimized to provide sufficient strength and rigidity to resist bending or twisting that may occur during placement or removal of the vehicle backstop 9. The first bracket 3 and the second bracket 4 can be designed as a straight rod or a shape with a certain curvature to adapt to the contours of different vehicle tires and improve the adaptability and stability of the contact between the backstop and the tire.

[0045] In one embodiment, the first vertical rod 6 and the second vertical rod 7 are made of rectangular tubing or circular tubing to provide structural strength and stability, while the hollow design of the tubing reduces the overall weight. In another embodiment, the connection between the vertical rod and the bidirectional telescopic rod 2 is bolted, and additional stability and anti-loosening performance are provided by nuts and washers. In yet another embodiment, the first bracket 3 and the second bracket 4 are designed as adjustable structures. By setting adjustment holes or adjusting bolts, the operator can fine-tune the position and angle of the bracket according to the actual size of the tire. Through the above-mentioned embodiment, the connection structure between the bidirectional telescopic rod 2 and the first bracket 3 and the second bracket 4 of the device not only ensures the stable placement of the backstop, but also improves the adaptability of the device and the convenience of operation through the reasonable design and layout of the vertical rods.

[0046] As a preferred example, the first bracket 3 is integrated with the slide bar 22 , and the second bracket 4 is integrated with another slide bar 22 .

[0047] Specifically, the first and second brackets 3 and 4 are each designed as an integral structure with their corresponding slide bars 22, simplifying the connection between components and reducing the number of parts required for assembly. This also enhances the stability and durability of the overall structure. The slide bars 22 are designed to be of sufficient length and strength to accommodate their function within the bidirectional telescopic rod 2. The outer surface of the slide bars 22 can be smooth or textured to enhance sliding fit with the transverse sleeve 21. The connection between the first and second brackets 3 and 4 and their respective slide bars 22 can be integrally formed or achieved through machining. For example, the brackets can be integrally formed with the slide bars 22 through casting, forging, or machining. This integrated arrangement allows the extension and retraction of the slide bars 22 to directly drive the movement of the brackets, enabling rapid adjustment and positioning of the vehicle's backstop 9. This design reduces the play and looseness that can occur with traditional connection methods, improving the operational accuracy and reliability of the device. This integrated arrangement can be achieved through a variety of manufacturing processes, such as metal casting, powder metallurgy, and injection molding. The appropriate process is selected based on the material and design requirements to ensure structural integrity and functionality.

[0048] In one embodiment, the first bracket 3 and the second bracket 4 are integrally formed with the slide bar 22 through a metal casting process, ensuring the sturdiness and integrity of the structure. In another embodiment, the integrated structure of the slide bar 22 and the bracket is manufactured using a high-strength plastic material through an injection molding process, which is suitable for lightweight design requirements. In yet another embodiment, the design of the axial groove 23 and the fixing screw of the slide bar 22 takes into account the matching accuracy after being integrally formed with the bracket, ensuring stability during the telescopic process and reliability of the locking. Through the above-mentioned embodiment, the integrated setting of the present device not only improves the efficiency of manufacturing and assembly, but also enhances the stability and durability of the overall structure by reducing the number of components and connection points, meeting the requirements of quick placement of the vehicle backstop 9.

[0049] As a preferred example, the bidirectional telescopic rod 2 is a manual telescopic rod.

[0050] As a preferred example, the bidirectional telescopic rod 2 may be an electric telescopic rod, and the controller of the electric telescopic rod is provided on the handle 11 .

[0051] Specifically, the bidirectional telescopic rod 2 uses an electric drive system to achieve its telescopic function. The electric telescopic rod includes at least one electric motor and mechanical transmission components connected to the motor, such as gears, a slide rod 22, or a lead screw, to drive the movement of the telescopic rod. A controller is integrated into the handle 11 of the handrail 1, allowing the operator to conveniently control the telescopic movement of the electric telescopic rod while holding the handle 11. The controller may include input devices such as buttons, switches, or a touch screen. The controller's user interface is intuitive, allowing the operator to control the extension or retraction of the telescopic rod with simple operations. For example, pressing a button activates the motor to automatically extend or retract the telescopic rod. The controller design incorporates necessary safety features, such as an emergency stop button, overload protection, and a mechanism to prevent incorrect operation, to ensure safe operation. The power supply for the electric telescopic rod can be a built-in rechargeable battery or an external power supply. The power supply design must meet the power requirements of the electric telescopic rod and provide sufficient operating time. The motor selected for the electric telescopic rod should consider its power, torque, and response speed to meet the performance requirements under different operating conditions.

[0052] In one embodiment, the electric telescopic rod uses a stepper motor to provide precise telescopic control, and the position of the telescopic rod can be accurately located through the input signal of the controller. In another embodiment, the controller is designed as a panel with LED indicator lights, which displays the current status of the telescopic rod, such as position, power level and other information, for easy monitoring by the operator. In yet another embodiment, the motor of the electric telescopic rod is connected to the slide bar 22 through a transmission method of a screw and a nut to achieve smooth and uniform telescopic action. Through the above embodiment, the electric telescopic rod of the present device provides automated telescopic control, reducing the labor intensity of the operator during the placement of the vehicle backstop 9. At the same time, the controller integrated on the handle 11 makes the operation more intuitive and convenient.

[0053] As a preferred example, the first bracket 3 and the second bracket 4 are respectively telescopic brackets.

[0054] Specifically, the first bracket 3 and the second bracket 4 are both designed to be retractable structures, so that each bracket can be adjusted according to the size of the vehicle tire to accommodate tires of different widths.

The telescopic bracket is made of high-strength lightweight materials, such as aluminum alloy, carbon fiber or reinforced plastic, to ensure stability and durability during the telescopic process. The telescopic part of the bracket is provided with a locking mechanism, such as a buckle, bolt or locking pin, which is used to fix the bracket after adjusting to the appropriate position to prevent displacement during use. The ends of the first bracket 3 and the second bracket 4 are respectively connected to the vehicle backstop 9, and the end design may include a fixing device for the backstop, such as a clamp, sleeve or strap, to ensure the stability of the backstop during use.

[0055] In one embodiment, the telescopic bracket adopts a slide rail design, and the length adjustment is achieved by means of a slider and a guide rail provided inside the bracket, which is easy to operate and accurate in positioning. In another embodiment, the locking mechanism is designed as a spring-loaded buckle. When the bracket is adjusted to the desired position, the bracket can be locked by pressing the buckle, and the length can be adjusted by releasing the buckle. In yet another embodiment, the backstop fixing device at the end of the bracket adopts an adjustable sleeve design, and its diameter is adjusted by rotating the sleeve to accommodate backstops of different sizes. Through the above-mentioned embodiment, the telescopic bracket of the present device provides a high degree of adaptability and flexibility, so that the operator can quickly adjust the length of the bracket according to the actual vehicle tire size, thereby achieving safe and quick placement of the vehicle backstop 9.

[0056] As a preferred example, the moving wheel 5 includes a rotating wheel and a fixed bracket. The rotating wheel may also be provided with a braking device for fixing the position of the vehicle backstop 9 placement device during the placement process.

[0057] Specifically, the moving wheel 5 is composed of a rotating wheel and a fixed bracket, wherein the rotating wheel is responsible for the rolling movement of the device, and the fixed bracket is used to fix the rotating wheel and is connected to the bottom of the bidirectional telescopic rod 2. The rotating wheel can be a solid wheel or a wheel with spokes, and its material selection and size design take into account the load-bearing capacity and mobile flexibility to adapt to different ground conditions. A braking device is provided on the rotating wheel, which can be manually operated or automatically triggered, and is used to quickly fix the position of the device during the placement of the vehicle stop 9 to prevent sliding or shifting. The braking device can adopt mechanical braking, such as brake pads and brake drums, or adopt various forms such as electromagnetic braking to ensure the reliability and stability of the braking. The operation of the braking device is designed to be simple and quick, and the operator can achieve braking or release through a single action, thereby improving operational efficiency.

[0058] In one embodiment, the braking device is a manually operated brake pedal. When the operator places the vehicle backstop 9, he steps on the pedal to activate the braking device and fix the position of the device. In another embodiment, the braking device is an electromagnetic brake, which is controlled by a button on the controller to achieve rapid braking and release, and is suitable for the automated operation of an electric telescopic rod. In yet another embodiment, the braking device is integrated with the rotating wheel and adopts an expandable brake pad. When the braking device is activated, the brake pad expands and contacts the wheel rim to achieve braking. Through the above-mentioned embodiment, the movable wheel 5 of the device and its braking device provide stable and reliable movement and fixing functions, ensuring the safety and accuracy of the vehicle backstop 9 during the placement process, while being easy to operate and improving work efficiency.

[0059] As a preferred example, the second ends of the first bracket 3 and the second bracket 4 are respectively provided with clamping mechanisms for clamping and placing the vehicle backstop 9 .

[0060] Specifically, the second ends of the first bracket 3 and the second bracket 4 are respectively equipped with a clamping mechanism, which is designed to firmly clamp the vehicle backstop 9 to prevent it from sliding or falling off during the movement or placement of the device. The clamping mechanism includes at least one pair of clamping arms, one end of the clamping arm is hinged to the second end of the bracket, and the other end has a clamping surface that matches the shape of the vehicle backstop 9. The backstop is clamped by the opening and closing action of the clamping arm. The opening and closing of the clamping mechanism can be achieved by manual operation, electric drive or other mechanical means to ensure the reliability and convenience of the clamping action. The clamping mechanism is equipped with a locking device, such as a spring, ratchet or locking pin, which is used to lock the backstop after the clamping arm is closed to prevent it from loosening due to vehicle movement or other external forces. - Adjustment function: The design of the clamping mechanism takes into account the adaptability of backstops of different sizes. The length of the clamping arm and the shape of the clamping surface can be adjusted to accommodate backstops of different specifications.

[0061] In one embodiment, the clamping mechanism is a manually operated lever-type clamping arm, which amplifies the clamping force through the lever principle, and the operator controls the opening and closing of the clamping arm by pressing or rotating the lever.

Through the above embodiment, the clamping mechanism of the present device provides a stable and reliable solution for clamping the vehicle backstop 9, which is easy to operate and highly adaptable, and effectively improves the safety and efficiency of the placement of the vehicle backstop 9.

[0062] An embodiment of a method of use of the present application:

[0063] The operator moves the device to the tire side of the target vehicle by holding the handle 11 on the handrail 1. Utilizing the rotation ability of the moving wheels 5, the device can be flexibly moved in the vehicle parking area.

[0064] According to the size of the vehicle tire, the operator adjusts the length of the first bracket 3 and the second bracket 4 through the telescopic mechanism to ensure that the bracket can adapt to the width of the tire. If the bracket is a telescopic bracket, it can be expanded to a length suitable for the width of the tire.

[0065] The operator operates the clamping mechanism to firmly clamp the vehicle back-up device 9 at the second ends of the first bracket 3 and the second bracket 4 , and prepares to place the vehicle back-up device 9 .

[0066] If necessary, the operator can adjust the length of the bidirectional telescopic rod 2 electrically or manually to adapt to the specific position of the vehicle tire.

[0067] The operator pushes the vehicle backstop 9 to the predetermined position of the tire, and ensures that the backstop is stably placed through the locking function of the clamping mechanism to prevent the vehicle from sliding or slipping.

[0068] After the vehicle backstop 9 is placed in place, the operator can use the brake device on the moving wheel 5 to fix the position of the device to ensure that the device will not move during the parking of the vehicle.

[0069] It is understood from common technical knowledge that the present invention may be implemented through other embodiments that do not depart from its spirit or essential features.
