Description

Technical Field

[0001] This utility model relates to the field of tire membrane carts, and in particular to a fast and safe tire membrane changing cart. Background Technology

[0002] In the past, automotive design was primarily driven by practicality, resulting in a relatively singular aesthetic. Now, consumers view cars as an extension of their personal taste, seeking emotional resonance through design, such as a sense of sportiness, technology, and luxury. Therefore, higher demands are placed on aspects like smooth lines, lighting design, and color texture. To meet these demands, automotive exterior components require more diversified design in terms of both styling and function. Consequently, industrial production lines involve a wide variety of tires, tooling, and other equipment, occupying a large area and making management not only complex but also time-consuming and labor-intensive.

[0003] Therefore, it is necessary to provide a fast and safe tire membrane changing cart to solve the above-mentioned technical problems. Summary of the Invention

[0004] To solve the above-mentioned technical problems, this utility model provides a fast and safe tire changing cart.

[0005] This utility model provides a fast and safe tire membrane changing cart, including a frame, a tire membrane support frame slidably connected to the top of the frame, a drive device for controlling the movement of the tire membrane support frame relative to the frame installed on the frame, a rear protective plate, a left protective plate and a right protective plate fixed at the top edge of the tire membrane support frame, the rear protective plate, the left protective plate and the right protective plate forming a U-shaped structure, and a number of rolling balls installed on the top of the tire membrane support frame.

[0006] Preferably, each of the four bottom corners of the membrane support frame is fixed with a sliding rod, and the sliding rod is slidably connected inside the vehicle frame. The sliding rods make the membrane support frame slide up and down more smoothly.

[0007] Preferably, the drive device includes a threaded rod that is threadedly connected to the vehicle frame. The top end of the threaded rod contacts the bottom of the tire membrane support frame, and a handwheel is fixed to the bottom end of the threaded rod. Rotating the handwheel drives the threaded rod to rise and fall, thereby causing the tire membrane support frame to rise and fall.

[0008] Preferably, the bottom four corners of the frame are equipped with omnidirectional self-locking wheels for moving the frame. The omnidirectional function can be used to flexibly adjust the direction, and the self-locking device can be used to fix the position to prevent the tooling from slipping or tipping over.

[0009] Preferably, a large hemispherical seat is embedded and fixed at the top of the membrane support frame, and the rolling ball is embedded and rolled inside the large hemispherical seat to make the rolling ball roll more smoothly. The rolling ball is made of high carbon chromium steel (HRC>58), and is quenched and tempered at low temperature. The surface roughness is <0.05μm, the diameter tolerance is controlled at the μm level, and the spherical error is <0.1μm, ensuring high hardness, wear resistance and fatigue resistance, and can stably support 80~180kg of membrane.

[0010] Compared with related technologies, the present invention provides the following beneficial effects:

[0011] The high load-bearing capacity and wear resistance of the ball, along with the height adjustment function of the drive unit, make it adaptable to the installation, disassembly, and storage needs of various sizes of tire films, covering diverse production scenarios in industrial settings.

[0012] The 360-degree rolling design of the ball significantly reduces frictional resistance during membrane movement, and the drive unit can quickly adjust the height, shortening the membrane replacement time (shortening the cycle time) and improving the efficiency of industrial mass production.

[0013] General-purpose tooling replaces various specialized tire film tooling, reducing floor space and simplifying on-site management processes; ergonomic design reduces worker labor intensity and downtime caused by operator fatigue or injury, providing support for interior and exterior trim suppliers to adapt to complex production requirements.

[0018] The following description is based on the accompanying drawings and embodiments.

[0019] Please see Figures 1-3 A fast and safe tire membrane changing cart mainly consists of a frame 1, a tire membrane support frame 2, a drive unit 3, a protective structure, and a ball bearing assembly. Its structural design and functional integration enable efficient and safe tire membrane replacement. The specific working principle and technical features are as follows:

[0020] The main body of the vehicle is the frame 1, and a membrane support frame 2 is mounted on its top via a sliding connection. The two are precisely guided vertically by slide rods 8. Specifically, slide rods 8 are fixed at the four bottom corners of the membrane support frame 2. The slide rods 8 are slidably connected in the pre-set guide grooves inside the frame 1 to ensure that the membrane support frame 2 remains stable during up and down movement and to avoid tilting or jamming.

[0021] A drive unit 3 is installed on the frame 1 to control the vertical displacement of the tire membrane support frame 2 relative to the frame 1. The core of the drive unit 3 is a threaded rod 9, which passes through the bottom of the frame 1 via a threaded connection. Its top end contacts the bottom of the tire membrane support frame 2, and a handwheel 10 is fixed at its bottom end. By rotating the handwheel 10, the threaded rod 9 can be driven to move up and down axially, thereby pushing the tire membrane support frame 2 to move up and down along the slide bar 8, realizing the height adjustment function.

[0022] The top edge of the membrane support frame 2 is fixed with a rear protective plate 4, a left protective plate 5, and a right protective plate 6, which together form a U-shaped structure to provide semi-enclosed protection for the membrane, preventing it from slipping off due to inertia or operational errors during movement or adjustment.

[0023] The top of the membrane support frame 2 is also embedded with multiple large hemispherical seats 12, and each large hemispherical seat 12 has a rolling ball 7 installed inside. The 360-degree rolling design of the rolling ball 7 can significantly reduce the frictional resistance between the membrane and the support surface, making the movement of the membrane on the support frame smoother and reducing the operating force.

[0024] The bottom four corners of the frame 1 are equipped with universal self-locking wheels 11, which can flexibly adjust the movement direction of the trolley through the universal function, and fix the position through the self-locking device to prevent the tooling from slipping or tipping over due to external force when it is stationary, thus ensuring the safety of operation.

[0025] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
