Description

Technical Field

[0001] This utility model belongs to the field of automotive anti-skid chain technology, specifically, it relates to fully automatic automotive anti-skid chains. Background Technology

[0002] Tire chains are auxiliary devices used to improve tire traction on wet or icy surfaces. They effectively prevent tires from losing control or slipping under these conditions, thereby improving vehicle traction and safety. Current methods for installing tire chains generally rely on manual operation, requiring a series of complex steps: first, debris must be cleaned from the tire surface; the tire chains are laid flat under the tire; the tire is moved to press the chains into place; then, the positions of each connection point of the tire chains are individually aligned; finally, the tensioning device is repeatedly adjusted to ensure the chain adheres closely to the tire. This process not only requires skilled operators but also involves prolonged periods of bending over. Statistics show that experienced drivers take an average of 15-20 minutes to install tire chains on one side, while for inexperienced users, it can take more than half an hour.

[0003] It is evident that manual installation of snow chains presents significant technical challenges: the reliance on manual operation results in low efficiency, time-consuming and labor-intensive processes, high operational complexity, and inconvenience. This severely restricts the rapid deployment capability of snow chains in sudden severe weather events and reduces the willingness of ordinary car owners to use them.

[0004] In view of this, this utility model is proposed. Utility Model Content

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Example 1

[0050] like Figures 1 to 9 As shown, the fully automatic car snow chain described in this embodiment includes a snow chain assembly 2, a storage bracket assembly 3, and a support arm assembly 4;

[0051] The anti-skid chain assembly 2 includes a front traction member 21, a rear traction member 22, a chain rope 23, an anti-slip block 24, an elastic rope 26, a winch 27, and a side connecting rope 25. As shown in the attached figure, the front traction member 21 and the rear traction member 22 are snap-fit ​​connected. One end of the chain rope 23 is connected to the front traction member 21, and the other end is wrapped around the tire surface and connected to the rear traction member 22. There are two chain ropes 23. The anti-slip block 24 connects the adjacent chain ropes 23 and covers the tire surface. The front traction component 21 includes a front U-shaped elastic clip 2101, two front traction side end pieces 2102, a gripping protrusion 2103, and anti-slip spikes 2104. The two ends of the front U-shaped elastic clip 2101 are connected to the front traction side end pieces 2102, symmetrically arranged on both sides, for clamping onto the tire. Two gripping protrusions 2103 are respectively located on the front traction side end pieces 2102, for cooperating with the front gripping arm 31 of the storage bracket assembly 3 for gripping. The anti-slip spikes 2104 are located on the inner wall of the front traction side end pieces 2102 to enhance friction with the tire. The rear traction component 22 includes a rear U-shaped elastic clip 2201, two rear traction side end pieces 2202, and a worm gear. The two ends of the rear U-shaped elastic clip 2201 are connected to the rear traction side end pieces 2202. A winch 27 is mounted on the rear traction side end pieces 2202 and driven by the worm gear, which is driven by a second drive mechanism. There are several elastic ropes 26 that can be attached to the tire sidewall. One end of the elastic rope 26 is connected to the chain rope 23, and the other end is provided with a through hole. One end of the side connecting rope 25 is connected to the winch 27, and the other end passes through the through hole and is connected to the front traction member 21.

[0052] The U-shaped elastic clips here use high-polymer elastic U-shaped components, which combine wear resistance and anti-slip properties. The anti-slip blocks 24 can be made of wear-resistant polymers, aluminum alloys, stainless steel, etc., and the number of anti-slip blocks 24 is set according to requirements, evenly spaced. The chain rope 23 can be made of metal, wear-resistant polymers, etc., and the elastic rope can be made of polymer materials; of course, the choice can be made according to requirements. When the winch 27 tightens, it will pull the side connecting rope 25 taut, causing the chain rope 23 to spread out and completely cover the tire surface, while also ensuring the stability of the front and rear traction components. Additionally, to eliminate the influence of debris when the winch 27 retracts the side connecting rope 25, a dustproof port 2209 is designed at the inlet of the winch 27, made of elastic rubber, which can remove any dust and debris that may be brought in. The winch 27 is driven by a series of components, as shown in the attached diagram, including a worm gear 2203, a first worm gear 2204, a winch shaft 2205, a first worm gear 2206, a worm gear spline head 2207, and a locking groove 2208. The winch 27 is rotatably mounted on the winch shaft 2205, which is fixedly mounted on the side end. The winch 27 has teeth on its outer circumference that mesh with the first worm gear 2204, which is driven by the worm gear 2203. The worm gear 2203 and the first worm gear 2206 form a worm gear mechanism. The top of the first worm gear 2206 is the worm gear spline head 2207, which is connected to the rear gripping arm 32 below. The locking groove 2208 is the locking position during the transmission connection when the rear gripping arm 32 is engaged to complete the gripping.

[0053] The storage bracket assembly 3 includes a mounting frame 33, a front gripper arm 31, a rear gripper arm 32, a first drive mechanism, and a second drive mechanism. The first drive mechanism drives the front gripper arm to store and place the front traction member 21, and the second drive mechanism drives the rear gripper arm 32 to store and place the rear traction member 22. The front gripper arm 31, the rear gripper arm 32, the first drive mechanism, and the second drive mechanism are all mounted on the mounting frame 33. Referring to the attached drawings, the mounting frame 33 consists of two mounting seats 3301 and four grooved slide rails 3302. The two mounting seats 3301 are square and form a cuboid frame with the four grooved slide rails 3302. The front gripper arm 31 and the rear gripper arm 32 are both connected to the grooved slide rails 3302 through the grooves in the base.

[0054] The front gripper arm 31 comprises a front gripper base 3101, a lower support arm 3104, an upper support arm 3110, a linkage lever 3108, a linkage pull plate 3113, a jaw 3111, a gear, a lower support arm limiting step 3105, a lower support arm groove 3106, a lower support arm protrusion 3107, a lever roller 3109, a pull plate guide hole 3112, a stepped screw 3114, a dust cover 3115, and a toothed edge at the bottom of the upper support arm 3116. As shown in the attached diagram, the base groove 3102 on the front gripper base 3101 is a four-corner rounded side groove that engages with the groove slide rail 3302, allowing the front gripper arm 31 to slide. One end of the lower support arm 3104 is connected to the front gripper base 3101, and the other end is rotatably connected to the upper support arm 3110 via a stepped screw 3114. The top of the upper support arm 3110 is a toothed edge, namely the bottom toothed edge 3116 of the upper support arm, which meshes with the gear set 3103 mounted on the lower support arm 3104. The upper support arm 3110 is driven to rotate by a first drive mechanism, which includes a first motor 51 and a motor mount. The first motor 51 is mounted on the front gripper base 3101 via the motor mount. The output end of the first motor 51 transmits power to the gear set 3103, thereby enabling the upper support arm 3110 to rotate through gear transmission. One end of the linkage lever 3108 is a lever roller 3109, which is rotatably mounted to the upper support arm 3110 with a screw in the middle. The straight groove at the tail end is screwed to the linkage pull plate 3113, and the screwed screw can slide within the straight groove at the tail end. Two caliper claws 3111 are symmetrically arranged and rotatably connected to the upper support arm 3110 and the linkage pull plate 3113. They are used to grip the gripping protrusion 2103 of the front traction member 21, thereby achieving the effect of gripping the front traction member 21. The groove 3106 of the lower support arm is used to limit the lever roller 3109; the limiting step 3105 of the lower support arm is used to block the lever roller 3109, causing the linkage lever 3108 to rotate clockwise, thereby driving the linkage pull plate 3113 to move upward, and then closing the caliper claws 3111 through the pull plate guide hole 3112 on the linkage pull plate 3113; the protrusion 3107 of the lower support arm is used to press against the lever roller 3109, causing the linkage lever 3108 to rotate counterclockwise, thereby driving the linkage pull plate 3113 to move downward, and then opening the caliper claws 3111 through the pull plate guide hole 3112 on the linkage pull plate 3113. The gear set dust cover 3115 covers the gear set to prevent debris or dust from entering.

[0055] The rear gripper arm 32 includes a rear gripper base 321, interlaced gears 3203, an inner spline shaft 3204, a spline bushing 3205, inner spline teeth 3206, a raised edge 3207, etc. The base groove 3202 of the rear gripper base 321 is a circular groove at the four corners, which meshes with the groove slide rail 3302, so that the rear gripper arm 32 can slide. Splined bushing 3205 is mounted on rear gripper base 321. Inner splined shaft 3204 is mounted inside splined bushing 3205 via bearings. The bottom end of inner splined shaft 3204 is connected to interlocking gear 3203, and the other end passes through the base and is detachably connected to worm gear. Referring to the attached diagram, its top end is inner splined tooth 3206, which meshes with the worm spline head 2207 of rear traction member 22. Protruding edge 3207 is the outer protrusion of inner splined shaft 3204. When the splines are engaged, the protruding edge 3207 rotates to the locking groove 2208 position to achieve gripping of rear traction member 22. Here, inner splined shaft 3204 is driven by a second drive mechanism, which includes a second motor 52. The second motor 52 is mounted on rear gripper base 321 via a motor mount, and the motor output is driven by interlocking gear 3203, thereby driving inner splined shaft 3204.

[0056] The front grab arm 31 and rear grab arm 32 described here are examples of mechanical structures; other forms can also be used, as long as they enable the retraction and extension of the front traction member 21 and rear traction member 22. Additionally, the storage bracket assembly 3 in this example is equipped with a bracket dust cover 34. The dust cover 34 can be made of plastic or aluminum alloy and covers all four surfaces of the storage bracket assembly 3, providing protection for the internal components.

[0057] The support arm assembly 4 includes a main support arm 401, a rectangular arm 402, a bracket outer tube 403, a telescopic tube 404, a hollow screw 405, a second gear set 406, a third gear set 407, interlocking teeth 408, a second worm gear 409, a second turbine gear 410, a first gear 411, a second gear 412, and a second dust cover 413. Referring to the attached diagram, one end of the main support arm 401 is connected to the vehicle body and fixed in a suitable position near the tire. The other end is rotatably connected to one end of the rectangular arm 402 via a bearing, forming a movable joint mechanism. The rectangular arm 402 is a rectangular support tube with an outer shell, and the rectangular arm 402 can rotate around the axis of the main support arm 401. The rotation is driven by the fifth drive mechanism, which includes a worm drive motor 55, which is installed on the upper part of the rectangular arm 402. The output end of the worm drive motor 55 meshes with the interlaced teeth 408. The interlaced teeth 408 and the second worm 409 are integrated and synchronized. The second worm 410 on the outer wall of the main support arm 401 meshes with the second worm 409, thereby realizing the rotation of the rectangular arm 402 around the main support arm 401.

[0058] The outer tube 403 of the support is sleeved on the outside of the telescopic tube 404. The inner wall of the outer tube 403 has a groove, and the outer wall of the telescopic tube 404 has a protrusion that fits into the groove. The outer wall of the outer tube 403 is mounted on the bottom end of the rectangular arm 402 by a bearing, and the outer wall has a keyway that forms an integral part with the gear 411. The telescopic tube 404 has a protrusion on its outer wall that fits into the groove on the inner side of the outer tube 403, allowing the two to slide axially. One end of the inner side has trapezoidal threads that fit into the hollow screw 405, and the other end is welded to the mounting base 3301 of the housing support assembly 3. The left end of the hollow screw 405 is rotatably connected to the left end of the outer tube 403 of the support via a bearing and bearing seat. The gear 412 has internal threads, and its tail is screwed and anchored to the hollow screw 405 to form an integral unit. The hollow screw 405 and the trapezoidal threads at the tail of the telescopic tube 404 form a screw drive. When the gear 412 rotates with the hollow screw 405, the telescopic tube 404 will move axially. The dust cover 413 covers and protects the rectangular arm 402, gear set, and other components.

[0059] A third drive mechanism and a fourth drive mechanism are installed at the lower part of the rectangular arm 402. The third drive mechanism includes a third motor 53, and the fourth drive mechanism includes a fourth motor 54. The third motor 53 drives the support outer tube 403 to rotate through gear set 2 406 meshing with gear 1 411. The support outer tube 403 drives the telescopic tube 404 to rotate, which in turn drives the mounting base 3301 of the storage support assembly 3 to rotate, thereby realizing the rotation of the storage support assembly 3 and achieving the purpose of retracting and extending the anti-slip chain assembly 2. The fourth motor 54 drives the hollow screw 405 to rotate through gear set 3 407 meshing with gear 2 412, thereby causing the telescopic tube 404 to move axially. It should be noted that when the third motor 53 drives the outer tube 403 of the support to rotate, since the telescopic tube 404 is screwed to the hollow screw 405, the telescopic tube 404 and the outer tube 403 of the support rotate synchronously, and at the same time, the telescopic tube 404 will also move along the axial direction of the hollow screw 405. In order to counteract this axial displacement, it is necessary to coordinate with the motor control, that is, control the rotation of the fourth motor to make the hollow screw 405 rotate accordingly. The screw and the telescopic tube rotate synchronously to keep the axial position of the hollow screw 405 unchanged.

[0060] The control of electrical components can be achieved through a controller installed in the car's cockpit. The controller is electrically connected to the car battery, the first motor 51, the second motor 52, the third motor 53, the fourth motor 54, and the worm gear drive motor 55, and is powered by the car battery. The storage bracket assembly 3 is capable of continuous rotation for retracting and extending the chain rope 23. For the electrical component connections within the storage bracket assembly 3, an electric slip ring 415 structure can be used, as shown in the attached diagram. Figure 9As shown, the slip ring sleeve 414 cooperates with the electric slip ring 415, adapting to the electrical connection of the rotating mechanism. Preferably, the rear grab arm 32 is provided with an electromagnetic induction switch 57, and the front traction member 21 is provided with a magnetic induction reflection area 56. After the electromagnetic induction switch 57 detects the magnetic induction reflection area 56, the controller then controls the second motor 52 to start and tighten the side connecting rope 25. That is, electromagnetic induction is added to the controller connection control. This is only to provide one possibility for the application of existing electromagnetic induction. Of course, other methods can also be adopted. It should be noted that this example only applies existing electrical components such as motors and does not involve improving the structure and control of electrical components. The contents of circuits and electrical control are disclosed in the prior art and will not be described in detail here.

[0061] When installing anti-skid chains:

[0062] 1) The rectangular arm 402 will rotate along the axis of the main support arm 401 under the drive of the worm drive motor 55, approaching the tire to the set position. At the same time, under the drive of the fourth motor 54, the storage bracket assembly 3 will extend laterally to the set position. Meanwhile, the upper support arm 3110 of the two symmetrically installed front gripping arms 31 will open under the drive of the first motor 51, clamping the U-shaped front traction member 21 towards the tire. As the upper support arm 3110 rotates, after the lever roller 3109 reaches the position of the lower support arm groove 3106, the clamp 3111 will open to release the front traction member 21.

[0063] 2) After the front traction component 21 is secured, the upper support arm 3110 retracts under the drive of the first motor 51, and at the same time, the storage bracket assembly 3 rotates under the drive of the third motor 53 (in coordination with the fourth motor 54 to keep the telescopic tube 404 in position), that is, the stored anti-skid chain is released as the wheel 1 rolls forward.

[0064] 3) After the wheel 1 rotates to the set angle, the anti-skid chain is fully released. At the same time, the electromagnetic induction switch 57 receives the signal from the magnetic reflection zone 56 and performs the next setting action, that is, the U-shaped rear traction member 22 is locked onto the tire through the set program and forms a fastening with the front traction member 21. After the fastening is completed, the winch 27, driven by the second motor 52, tightens the side connecting ropes 25 on both sides. After the convex edge rotates to the position away from the locking groove 2208, the rear grab arm 32 can be separated from the rear traction member 22. The entire support arm and storage bracket retract to the set position, completing the installation of the anti-skid chain.

[0065] The process of storing anti-skid chains is the reverse of the above steps, thus automating the entire process of installing, disassembling, and storing anti-skid chains.
