Description

Technical Field

[0001] The invention relates to the field of automobile side guard plates, in particular to an automobile side guard plate which is easy to install and disassemble. Background Art

[0002] Automobile side guard panels, commonly known as side skirts, are protective decorative parts installed on the lower sides of the vehicle body. They are mainly located in the lower part of the door and the side contour area of ​​the body. Modern side guard panels can be divided into three categories according to their main functions: safety protection, decorative and practical.

[0003] Safety-protective side guards are designed to effectively prevent damage to the vehicle body caused by scratches and minor collisions during daily use, extending its service life while enhancing overall vehicle safety. These side guards are typically made of high-strength metal materials (such as aluminum alloys and steel alloys) or composite materials, offering excellent impact and corrosion resistance. Their structural design focuses on energy absorption and dispersion. When subjected to external impact, they absorb some of the impact energy through structural deformation, minimizing damage to the door and body.

[0004] Traditionally, safety-protective side guards rely on manual installation. The operator holds the guard assembly close to the intended mounting location on the vehicle's side panel, aligns the holes using auxiliary tools to precisely match the mounting holes, and then tightens the screws and bolts sequentially using manual or power tools to secure the guard. During disassembly, the retaining bolts or screws must be loosened one by one in reverse order to separate the guard from the vehicle. This process is not only complex and time-consuming, but also relies on manual labor.

[0005] Based on the above problems, there is an urgent need for a side guard plate for an automobile that is easy to install and remove, and optimizes the assembly and disassembly processes to improve the installation and disassembly efficiency. Summary of the Invention

Two connecting rods are hinged on the rotating circle, and the two connecting rods are symmetrically distributed on the rotating circle. The other ends of the connecting rods are hinged with a positioning piece, and each of the positioning pieces is fixed with a cross plate. The left and right ends of the mounting bracket are fixed with support ears, and the positioning piece and the adjacent support ear are slidably connected through, and a return spring is compressed between the positioning piece and the adjacent support ear. The left and right sides of the mounting bracket are fixed with limiting tooth plates, and the limiting tooth plates and the cross plates correspond to each other and conflict with each other.

[0011] Preferably, the support seat is provided with two hydraulic dampers, which are symmetrically distributed on the left and right sides of the mounting bracket, and the movable ends of the hydraulic dampers are key-connected to the bottom of the mounting bracket.

[0012] Preferably, the middle part of the mounting bracket is connected with a screw rod 2, which extends upward in the vertical direction and its height exceeds the top of the mounting bracket. The top key of the screw rod 2 is connected with a drive disk, and a lifting plate is threadedly connected to the screw rod 2. A guide rod is fixed on the mounting bracket, and the lifting plate is slidably connected to the guide rod.

[0013] Preferably, the front side of the support seat is embedded with two sliders, and the two sliders are symmetrically distributed on the left and right sides of the mounting bracket. Positioning columns are fixed in the sliders, and wedge-shaped blocking blocks are slid on the positioning columns.

[0018] The rotating disk is driven to rotate by external force, and the screw rod is rotated in a controlled manner, driving the movable frame and the positioning plate to move toward each other, thereby clamping and positioning the automobile mounting part clamped therebetween. As the movable frame moves, the straight rod moves synchronously, and the straight rod is inserted into the positioning hole and automatically aligned and plug-locked with the vehicle body mounting hole to complete a stable connection between the mounting bracket and the vehicle body. By tightening the locking pin, the extrusion block is compressed and then presses the wire rope, thereby achieving mechanical locking of the wire rope, thereby limiting the rotational freedom of the rotating disk, preventing the screw rod from rotating in the opposite direction due to external force, and ultimately preventing the clamping force between the movable frame and the positioning plate from being released, so that the straight rod and the vehicle body mounting hole are always kept in a locked state, thereby improving the structural safety and connection reliability of the entire vehicle during driving.

[0019] Through the cooperation of the lifting assembly and the supporting assembly, the mounting bracket and side skirts can be accurately and smoothly lifted to the target installation position. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0030] Next, combine Figures 1-9 A specific embodiment of the present invention is described in detail.

[0031] refer to Figure 1 and Figure 2 A side guard plate for an automobile that is easy to install and disassemble includes a controlled movable mounting bracket 1 as a load-bearing body. The front side of the mounting bracket 1 is detachably connected to a side skirt 12 for protecting the lower part of the door and the side area of ​​the vehicle body. The rear side of the mounting bracket 1 is provided with a controlled adjustable fixing component, which is adjusted and locked according to the installation requirements to achieve a stable connection between the mounting bracket 1 and the preset installation area of ​​the side area of ​​the vehicle body.

[0032] During the assembly phase, the side skirt 12 is pre-installed on the front side of the mounting bracket 1. The mounting bracket 1 is adjusted to the target position, and the fixing components on its rear side are adjusted to quickly lock the mounting bracket 1 with the mounting holes on the vehicle body, thereby completing the installation of the side skirt 12. During the disassembly phase, the fixing components are adjusted to disengage the mounting bracket 1 from the mounting holes on the vehicle body, thereby completing the disassembly of the side skirt 12. This effectively simplifies the traditional complex installation process that relies on hole-by-hole alignment and screw tightening, improves assembly and disassembly efficiency, and reduces the difficulty and labor intensity of manual operation.

[0033] refer to Figure 2 The fixing assembly includes four mobile frames 2 that are slidably connected to the mounting bracket 1. The four mobile frames 2 are grouped in pairs and are symmetrically distributed on the left and right sides of the mounting bracket 1. Each of the mobile frames 2 is slidably connected to a plurality of straight rods 21. A compression spring 22 is compressed between the straight rod 21 and the mobile frame 2 to provide a reset force for the straight rod 21. The straight rod 21 is slidably connected to the rear side wall of the mounting bracket 1, and is intended to achieve locking cooperation with the mounting hole on the vehicle body through the movement of the straight rod 21.

[0034] In order to realize the controlled movement of the straight rod 21, four screw rods 23 are connected to the rear side of the mounting bracket 1. In particular, the rotation of the screw rod 23 does not produce any linkage on the mounting bracket 1. The four screw rods 23 are arranged in a one-to-one correspondence with the four mobile racks 2, and each of the screw rods 23 is threadedly connected to the adjacent mobile rack 2.

[0035] refer to Figure 2 and Figure 3 The two adjacent screw rods 23 pass through one end of the mounting bracket 1 and are threadedly connected to a positioning plate 13. The positioning plate 13 is provided with positioning holes 11 that match the number and diameter of the straight rods 21, which are used to guide and limit the insertion of the ends of the straight rods 21 to achieve positioning and locking between the mounting bracket 1 and the vehicle body. The end of each screw rod 23 near the positioning plate 13 is keyed to a rotating disk 24 for receiving external driving force.

[0036] Before assembly, the side skirt 12 is pre-installed on the front side of the mounting bracket 1. The mounting bracket 1 is moved so that the car mounting part is located between the mobile frame 2 and the positioning plate 13. The external force drives the rotating disk 24 to rotate, and the screw rod 23 rotates synchronously, driving the mobile frame 2 and the positioning plate 13 to move toward each other, thereby clamping and positioning the car mounting part clamped therebetween. As the mobile frame 2 moves, the straight rod 21 moves synchronously in a controlled manner. The straight rod 21 is pre-tightened by the compression spring 22 and the limiting effect of the positioning plate 13, inserted into the positioning hole 11, and automatically aligned and plug-locked with the car body mounting hole, completing the stable connection between the mounting bracket 1 and the car body, thereby realizing the installation of the side skirt 12.

[0037] refer to Figure 3 and Figure 4In order to ensure that the straight rod 21 maintains a stable locking state with the positioning hole 11 and the vehicle body mounting hole during driving, and to prevent the connection from loosening or accidental unlocking due to vibration, impact or other external forces, the device is designed as follows: two locking blocks 26 are fixed to the rear side of the mounting bracket 1, and the two locking blocks 26 are arranged one-to-one with the two rotating disks 24. An extrusion block 27 is slidably connected in each of the locking blocks 26, and a movable space is formed between the extrusion block 27 and the locking block 26. A locking pin 261 is threadedly connected to the locking block 26, and the end of the locking pin 261 presses and contacts the extrusion block 27, causing the extrusion block 27 to move, and then a movable space is formed between the extrusion block 27 and the locking block 26, which gradually decreases. A steel wire rope 25 is wound around the outer circumference of the rotating disk 24, and the fixed end of the steel wire rope 25 is fixed to the rotating disk 24, and its movable end is inserted into the movable space formed between the adjacent extrusion block 27 and the locking block 26.

[0038] When the operator completes the installation of the side skirt 12 and confirms that the straight rod 21 has been inserted into the vehicle body mounting hole, the movable end of the wire rope 25 is inserted into the movable space formed between the adjacent extrusion block 27 and the locking block 26, and external force is used to tighten the locking pin 261, so that it presses the extrusion block 27, causing the extrusion block 27 to move and then press the wire rope 25, thereby achieving mechanical locking of the wire rope 25. This locking action fixes the movable end of the wire rope 25 in the locking block 26, thereby limiting the rotational freedom of the rotating disk 24, preventing the screw rod 23 from rotating in the opposite direction due to external force, and ultimately preventing the clamping force between the movable frame 2 and the positioning plate 13 from being released, so that the straight rod 21 and the vehicle body mounting hole are always kept in a locked state, thereby improving the structural safety and connection reliability of the entire vehicle during driving.

[0039] During the use of this device, the precise alignment of the mounting bracket 1 with the preset mounting hole on the vehicle body is the basis for achieving the subsequent plug-in locking of the straight rod 21 and the anti-loosening action of the locking pin 261, and is also a key link in achieving stable installation of the side skirt 12. However, in the traditional assembly method, the alignment process relies on manual adjustment, which is not only cumbersome and inefficient, but also easily affected by human factors, resulting in positioning errors and affecting the assembly quality. The mounting bracket 1 is provided with a lifting component, which realizes the rapid and precise alignment of the mounting bracket 1 with the mounting hole of the vehicle body through mechanical linkage, providing a reliable reference for subsequent locking actions.

[0040] refer to Figure 5 The lifting assembly includes a freely movable support base 3, which is stably installed on the ground to provide a stable installation platform and force fulcrum for the entire device. The support base 3 is slidably connected with the mounting bracket 1, that is, the mounting bracket 1 moves up and down on the support base 3 in a controlled manner. A force storage spring 31 is compressed between the mounting bracket 1 and the support base 3, and the initial lower force storage spring 31 is in a stretched state.

[0041] refer to Figure 6 The middle part of the mounting bracket 1 is fixedly connected to an annular guide frame 331, and the top of the annular guide frame 331 is connected to a rotating circle 33, and the rotating circle 33 rotates freely around the annular top surface of the annular guide frame 331. Two connecting rods 34 are hinged on the rotating circle 33, and the two connecting rods 34 are symmetrically distributed on the rotating circle 33. The other ends of the connecting rods 34 are hinged with a positioning piece 35, and each of the positioning pieces 35 is fixed with a horizontal plate 351. The left and right ends of the mounting bracket 1 are fixed with support ears 352, and the positioning piece 35 is slidably connected with the adjacent support ear 352, and a return spring 321 is compressed between the positioning piece 35 and the adjacent support ear 352.

[0042] refer to Figure 5 The left and right sides of the mounting bracket 1 are fixedly connected with a limit tooth plate 36. The limit tooth plate 36 corresponds to the horizontal plate 351 one by one and conflicts with each other. Initially, the horizontal plate 351 conflicts with the bottom of the limit tooth plate 36, forming a mechanical limit, so that the mounting bracket 1 is positioned at the preset low position of the support seat 3.

[0043] After the limit is released, under the action of the storage spring 31, the mounting bracket 1 slides upward along the support seat 3 and drives the side skirt 12 to rise synchronously.

[0044] After the mounting bracket 1 is released from its restricted position, it is driven by the restoring force of the force-accumulating spring 31 to rapidly move upward along the support base 3. However, this rapid ascent generates a significant impact force due to the excessive kinetic energy, which not only affects positioning accuracy but also damages structural components, reducing the stability and service life of the device. To improve the stability and controllability of the mounting bracket 1 during the lifting process, the present device incorporates the following design.

[0045] refer to Figure 8Two hydraulic dampers 353 are provided on the support seat 3, and the two hydraulic dampers 353 are symmetrically distributed on the left and right sides of the mounting bracket 1. The movable ends of the hydraulic dampers 353 are key-connected to the bottom of the mounting bracket 1. When the mounting bracket 1 moves upward under the action of the storage spring 31, the piston rod of the hydraulic damper 353 is synchronously extended and retracted, and a controllable damping force is applied to the movement process through its internal hydraulic system, thereby effectively slowing down the rising speed, absorbing impact energy, and improving the smoothness of movement.

[0046] Considering that the mounting bracket 1 and the side skirt 12 installed on the front side can be automatically lifted under the drive of the storage spring 31, in actual application, due to the assembly tolerance, vehicle body structure differences and positioning accuracy limitations, the lifted mounting bracket 1 still cannot accurately match the docking position of the vehicle body installation part, affecting the assembly efficiency and connection reliability.

[0047] To solve this problem and improve the alignment accuracy and lifting stability between the mounting bracket 1 and the target installation position, this device introduces a lifting component that works in conjunction with the force storage spring 31 to achieve accurate and smooth lifting of the mounting bracket 1 and the side skirt 12 to the target installation position.

[0048] refer to Figure 5 and Figure 6 The lifting assembly includes a screw rod 37 connected to the middle part of the mounting bracket 1. The screw rod 37 extends upward in the vertical direction and its height exceeds the top of the mounting bracket 1. The top key of the screw rod 37 is connected to a driving disk 371. External force acts on the driving disk 371 to realize the rotation of the screw rod 37. A lifting plate 38 is threadedly connected to the screw rod 37. The lifting plate 38 can be moved upward along its axial direction in a controlled manner under the rotation of the screw rod 37, thereby applying further lifting force to the mounting bracket 1 to achieve its precise positioning to the target installation position. A guide rod 381 is fixed to the mounting bracket 1, and the lifting plate 38 is slidably connected to the guide rod 381, aiming to guide the movement of the lifting plate 38 through the guide rod 381.

[0049] After the limit state is released, the mounting bracket 1 completes the initial lifting under the coordinated action of the force storage spring 31 and the hydraulic damper 353. At this time, although the height of the mounting bracket 1 is close to the target installation position, there are still slight deviations and incomplete docking. At this time, the operator applies external force to the drive disk 371 to drive the screw rod 2 37 to rotate. The lifting plate 38 slides upward along the guide rod 381 under the drive of the screw rod 2 37 until its top contacts the bottom of the mounting bracket 1. As the lifting plate 38 continues to move upward, it further lifts the mounting bracket 1 and the side skirt 12 in front of it and accurately positions it at the vehicle body installation position, and then achieves a firm connection between the mounting bracket 1 and the vehicle body through the fixing assembly.

[0050] In order to improve the stability and safety of the side skirt 12 during installation and operation and prevent it from deflecting or falling off when the vehicle is driving or colliding, the device provides a limiting component on the support seat 3 to limit and fix the side skirt 12.

[0051] refer to Figure 7 The front side of the support seat 3 is embedded with two sliders 39, and the two sliders 39 are symmetrically distributed on the left and right sides of the mounting bracket 1. The sliders 39 are pushed inward to achieve the effect of being hidden in the support seat 3. Positioning columns 312 are fixed in the sliders 39, and wedge-shaped blocking blocks 310 are slid on the positioning columns 312. The wedge-shaped blocking blocks 310 are embedded and slidably connected to the sliders 39, that is, the wedge-shaped blocking blocks 310 move downward to achieve the effect of being hidden inside the sliders 39. A pressure spring 311 is compressed between the blocking block 310 and the slider 39, and the pressure spring 311 is wound around the adjacent positioning column 312.

[0052] Before the side skirt 12 is installed, the slider 39 extends out of the support seat 3, and the positioning block 310 extends upward from the top of the slider 39, placing the side skirt 12 on the inside of the positioning block 310, that is, the positioning block 310 limits the side skirt 12 to prevent the side skirt 12 from tipping outward.

[0053] refer to Figure 8 and Figure 9 , two positioning rods 4 are detachably installed on the support seat 3, and the two positioning rods 4 are arranged one-to-one with the two sliders 39. The positioning rods 4 are all provided with sliding grooves, and the sliding grooves are fixed with guide posts 44, and the guide posts 44 are all slidably connected to the limit plates 41. This limit plate 41 is L-shaped and is used to limit and lock the top of the side skirt 12. A linear spring 43 is provided between the limit plate 41 and the positioning rod 4, and the top of the limit plate 41 and the positioning rod 4 is provided with pin holes (not numbered in the figure). The pin holes of the limit plate 41 and the positioning rod 4 are aligned and are jointly clamped with a latch 42. Initially, the lower linear spring 43 is in a stretched state, and the latch 42 is locked with the pin holes of the limit plate 41 and the top of the positioning rod 4, so that the limit plate 41 is locked with the positioning rod 4 and positioned at its top.

[0054] The height of the positioning rod 4 is higher than the overall height of the side skirt 12 , so that the limiting plate 41 can be effectively pressed against the top of the side skirt 12 to achieve the limiting function.

[0055] refer to Figure 8 Two symmetrically distributed mounting plates 45 are fixed to the side walls of the positioning rod 4. The mounting plates 45 are each provided with threaded holes 46 for further fixing the side skirts 12 to the front side of the positioning rod 4 by screws.

[0056] After the side skirt 12 is placed inside the positioning block 310, the pin 42 is pulled out. Under the action of the linear spring 43, the limit plate 41 is controlled to move downward until it contacts the top of the side skirt 12, thereby achieving preliminary locking of the limit plate 41 and preventing the side skirt 12 from tipping over during subsequent further locking operations.

[0057] After the side skirt 12 is initially locked by the side skirt 12, screws are screwed into the threaded holes 46 of the mounting plate 45 to further fit and fix the side skirt 12 to the front side of the positioning rod 4, thereby enhancing the stability of the connection and achieving precise positioning and firm locking of the side skirt 12 on the mounting bracket 1, effectively preventing it from shifting and falling off during assembly, transportation and vehicle operation.

[0058] During the disassembly stage, external force unscrews the locking pin 261, releasing its limiting effect on the extrusion block 27, so that the pressing force of the extrusion block 27 on the wire rope 25 disappears, and the wire rope 25 returns to a free state, thereby releasing the rotation restriction on the rotating disk 24. At this time, the external force drives the rotating disk 24 to rotate in the opposite direction, driving the screw rod 23 connected to its key to rotate in the opposite direction synchronously, and then drives the movable frame 2 and the positioning plate 13 threadedly connected to it to move in the opposite direction, releasing the clamping effect on the vehicle body mounting part, and then, the support seat 3 is moved outward as a whole, so that the mounting bracket 1 and the side skirt 12 connected to its front side are separated from the vehicle body mounting part, completing the rapid disassembly process of the entire device.

[0059] To facilitate the movement of the support base 3 on the ground, a plurality of evenly distributed self-locking rollers 32 are provided at the bottom of the support base 3. The operator pushes the support base 3 to move freely and accurately position it on the ground, reducing the intensity of manual operation and improving the efficiency of the device during assembly and disassembly.

Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible.
