Description

Technical Field

[0001] The present application relates to the technical field of car washers, and in particular to a track guide mechanism on a car washer. Background Art

[0002] In the car washing industry, the widespread use of automated car washing machines has greatly improved car washing efficiency and user experience. Among them, the guide mechanism of the car washing machine, as one of the core components, undertakes the important task of ensuring that the car washing machine moves stably and accurately during the cleaning process.

[0003] During the use of the existing track guide mechanism on the car washing machine, the guide mechanism often relies on the close fit between the guide rail and the guide wheel to achieve the orientation and guidance functions. Although this design can effectively prevent the car washing machine from deflecting or shaking during movement, after long-term operation, the friction loss problem between the guide rail and the guide wheel becomes increasingly prominent. Due to frequent sliding contact, the surface of the guide rail is prone to wear, and the guide wheel will also reduce its accuracy due to wear, which will affect the operation stability and service life of the car washing machine. In addition, the heat generated by friction may also have an adverse effect on the material properties, further aggravating the wear problem.

[0004] Secondly, the guide rails of existing guide mechanisms usually adopt an integral design or long-section splicing, which to a certain extent limits the convenience of disassembly and maintenance. When a part of the guide rail needs to be replaced due to wear, corrosion or damage, it is often necessary to disassemble and replace the entire section of the guide rail, which not only increases the maintenance cost, but also prolongs the downtime and affects the efficiency of the car washing machine. Especially for long guide rails, the difficulty and cost of disassembly and assembly are doubled.

[0005] In view of the above problems, a track guide mechanism on a car washing machine is now designed. Utility Model Content

[0006] The embodiment of the present application provides a track guide mechanism on a car washing machine to solve the problem that the guide mechanism in the related art often relies on the close fit between the guide rail and the guide wheel to achieve the orientation and guiding functions, and after long-term operation, the friction loss between the guide rail and the guide wheel is large.

[0007] In a first aspect, a track guide mechanism on a car washing machine is provided, comprising:

[0008] A track, wherein the track is hollow inside, and the two ends of the bottom of the track are bent inward to form a slideway, a guide wheel is slidably arranged on the slideway, a mounting plate is arranged at the bottom of the guide wheel, and the other end of the mounting plate extends downward and is connected to an external car washing machine;

[0009] The track is formed by splicing a plurality of steel rails, and two adjacent steel rails are connected by a connecting piece.

[0010] In some embodiments, the rail is n-shaped and hollow inside, with both ends and the bottom being open;

[0011] The two ends of the bottom of the rail are bent inward to form an L-shaped bending surface and a guide channel, and the tops of two adjacent L-shaped bending surfaces are enclosed to form a slideway;

[0012] The mounting plate is located inside the guide channel, and a gap is left between the mounting plate and the guide channel.

[0013] In some embodiments, the bottom of the L-shaped bending surface is horizontal and the side thereof is inclined.

[0014] In some embodiments, the guide wheel includes a support plate arranged inside the slide, a plurality of rotating shafts are rotatably arranged on the support plate, rollers are arranged at both ends of the rotating shafts, and the rollers are slidably arranged on the slide.

[0015] In some embodiments, a rubber sleeve is disposed outside the roller.

[0017] The connecting piece is sleeved on the outer sides of two adjacent steel rails, the connecting piece is in an N-shape and is adapted to the steel rails, and the connecting piece and the steel rails are connected by bolts.

[0018] The embodiment of the present application provides a track guide mechanism on a car washing machine, which forms a slideway by bending both ends of the bottom of the track inward, thereby reducing the friction loss between the guide wheel and the track and extending the service life. At the same time, the modular splicing track design is also easy to repair and replace, reducing the downtime caused by component damage and reducing the additional cost caused by replacing the guide rail as a whole.

[0025] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0026] The embodiment of the present application provides a track guide mechanism on a car washing machine, which can solve the problem that the guide mechanism in the related art often relies on the close fit between the guide rail and the guide wheel to achieve the orientation and guiding functions, and the friction loss between the guide rail and the guide wheel is large after long-term operation.

[0027] See also Figure 1-Figure 3 A track guide mechanism on a car washing machine includes: a track 1, the track 1 is hollow inside, the two ends of the bottom of the track 1 are bent inward to form a slide 2, a guide wheel 3 is slidably arranged on the slide 2, a mounting plate 4 is arranged at the bottom of the guide wheel 3, the other end of the mounting plate 4 extends downward and is connected to an external car washing machine, and a gap is left between the mounting plate 4 and the track 1; the track 1 is formed by splicing a plurality of steel rails 11, and two adjacent steel rails 11 are connected by a connecting piece 12.

[0028] The track 1 is hollow inside, which not only reduces the overall weight, but also provides space for installing other necessary components such as guide systems or electrical circuits. The two ends of the bottom of the track 1 are bent inward to form a slideway 2, which provides a stable and precise sliding path for the guide wheel 3.

[0029] The guide wheel 3 is firmly connected to the external car washer through the mounting plate 4 at its bottom. The other end of the mounting plate 4 extends downward to ensure that the guide wheel 3 can slide smoothly into the slideway 2 of the track 1.

[0030] When the car washing machine moves along the track 1, the guide wheel 3 rolls on the slideway 2 to provide a stable guiding effect. The guide wheel 3 reduces the friction between the slideway 2 and increases the smoothness and durability of the sliding.

[0031] The track 1 is composed of a plurality of rails 11 connected by connectors 12, making the assembly and disassembly of the track very flexible and convenient. When a part of the track needs to be replaced or repaired, it is only necessary to loosen the connector 12, replace the damaged rail 11, and then re-fix the connector 12, without having to replace the entire track.

[0032] The two ends of the bottom of the track 1 are bent inward to form the slideway 2, which reduces the friction loss between the guide wheel 3 and the track 1 and prolongs the service life. At the same time, the modular track design is also easy to repair and replace, reducing the downtime caused by component damage.

[0033] The modular rail design not only reduces manufacturing and transportation costs, but also reduces the additional costs caused by replacing the rails as a whole. In addition, the easy disassembly and installation characteristics also reduce the complexity and cost of maintenance work.

[0034] Specifically, the steel rail 11 in this embodiment is n-shaped and hollow inside, with both ends and the bottom being open; the two ends of the bottom of the steel rail 11 are bent inward to form an L-shaped bending surface 6 and a guide channel 7, and the tops of two adjacent L-shaped bending surfaces 6 are enclosed to form a slideway 2; the mounting plate 4 is located inside the guide channel 7, and a gap is left between the mounting plate 4 and the guide channel 7.

[0035] Rail 11 adopts a unique n-shaped design, which not only provides sufficient strength and stability, but also achieves lightweight through the internal hollow design, reducing material costs and overall weight. Both ends and the bottom of rail 11 are designed to be open, and this open design facilitates subsequent processing, installation and possible internal maintenance.

[0036] The two ends of the bottom of the rail 11 are bent inwards to form an L-shaped bending surface 6 , which not only enhances the structural strength of the rail but also guides the sliding path of the guide wheel 3 .

[0037] During the bending process, the two ends of the bottom extend inward, not only forming an L-shaped bending surface 6, but also naturally enclosing a guide channel 7.

[0038] The tops of two adjacent L-shaped bending surfaces 6 enclose a slideway 2. The width, depth and shape of the slideway 2 are strictly calculated to ensure that the guide wheel 3 can slide stably and smoothly therein.

[0039] A certain gap is intentionally left between the mounting plate 4 and the guide channel 7. The design of this gap takes into account the possible slight displacement or tilt of the guide wheel 3 during the sliding process, as well as the thermal expansion and contraction effect between the mounting plate 4 and the rail 11. The existence of the gap allows these slight changes to occur, thereby avoiding problems such as increased friction, noise or component damage caused by over-tightening or over-loosening.

[0040] The L-shaped bending surface 6 and the guide channel 7 optimize the sliding path and contact surface of the guide wheel 3, reduce friction resistance and wear, and improve sliding performance.

[0041] The N-shaped design and the internal hollow structure enhance the overall strength and stability of the rail 11; the reinforcement treatment of the L-shaped bending surface 6 further enhances the durability of the structure.

[0042] In this embodiment, the bottom of the L-shaped bending surface 6 is horizontal, and the side thereof is inclined.

[0043] Specifically, the two ends of the bottom of the rail 11 are bent inward twice to form an L-shaped bending surface 6, one side is bent to form a side inclined surface, and the second bending forms a bottom horizontal surface, and the side inclined surface and the bottom horizontal surface are enclosed to form the L-shaped bending surface 6. The two bending places of the L-shaped bending surface 6 are blunt-angled.

[0044] The two ends of the bottom of the rail 11 are precisely bent inward twice to form an L-shaped bending surface 6 .

[0045] This process consists of two main steps:

[0046] Bending once: First, the bottom end of the rail 11 is bent inward for the first time to form a side inclined surface. This inclined surface provides a gradually transitional sliding path for the guide wheel 3, which helps to reduce the impact and vibration during the sliding process.

[0047] Secondary bending: Then, on the basis of the side inclined surface, a second bending is performed to form a bottom horizontal surface. The bottom horizontal surface provides a stable support for the guide wheel 3, ensuring its stability during the sliding process.

[0048] The side inclined surface and the bottom horizontal surface are mutually enclosed to form a complete L-shaped bending surface 6. This L-shaped structure not only has excellent guiding performance, but also can limit the lateral movement of the guide wheel 3 to a certain extent, thereby improving the stability of the guide mechanism.

[0049] Obtuse angle treatment is performed at the two bending places of the L-shaped bending surface 6, i.e., the junction of the side inclined surface and the bottom horizontal surface. This treatment is to eliminate the sharp corners that may be generated during the bending process and reduce the wear and damage of these corners to the guide wheel 3.

[0050] The main purpose of the blunt angle treatment is to improve the durability and safety of the L-shaped bending surface 6. By eliminating sharp corners, the direct contact between the guide wheel 3 and these corners during the sliding process can be reduced, thereby reducing wear and noise. At the same time, the blunt angle treatment can also prevent the guide wheel 3 from being damaged or malfunctioning due to collision with sharp corners.

[0051] Specifically, Figure 4 As shown, the guide wheel 3 in this embodiment includes a support plate 31 arranged inside the slide 2, and a plurality of rotating shafts 32 are rotatably arranged on the support plate 31. Both ends of the rotating shafts 32 are provided with rollers 33, and the rollers 33 are slidably arranged on the slide 2.

[0052] The support plate 31 is the main part of the guide wheel 3, and provides a stable support base for the entire guide wheel 3. The material and thickness of the support plate 31 are selected according to actual needs to ensure that it can withstand various forces and moments generated by the guide wheel during sliding.

[0053] The rotating shafts 32 are supporting shafts of the rollers 33, which allow the rollers 33 to roll freely on the slideway 2. The number and layout of the rotating shafts 32 are determined according to the width of the slideway 2 and the load requirements of the guide wheels 3 to ensure that the guide wheels 3 can maintain balance and stability during sliding.

[0054] The roller 33 is a direct contact part between the guide wheel 3 and the slideway 2. The roller 33 is made of a wear-resistant, low-friction material to reduce friction resistance and wear during sliding. The diameter and width of the roller 33 are selected as required to ensure that it can roll smoothly on the slideway 2 and bear the load of the guide wheel 3.

[0055] When the car washer moves on the track, the roller 33 of the guide wheel 3 rolls and slides on the slideway 2. Compared with sliding friction, this rolling and sliding mode has lower friction resistance and higher sliding efficiency, which can significantly reduce the energy consumption and noise of the car washer during movement. The guide wheel 3 not only realizes the movement of the car washer on the track through the rolling and sliding of the roller 33 on the slideway 2, but also plays a guiding and stabilizing role. The roller 33 rolls along the predetermined path of the slideway 2, ensuring that the car washer can travel along the predetermined route.

[0056] In one embodiment, Figure 4 As shown, a rubber sleeve 5 is disposed outside the roller 33 .

[0057] The rubber sleeve 5 is made of a rubber material with high elasticity, high wear resistance and low friction coefficient. This material not only has good wear resistance, can reduce the friction loss between the roller 33 and the slideway 2, but also has good shock absorption and noise reduction effects, can reduce the noise and vibration of the car washing machine during movement.

[0058] The rubber sleeve 5 is closely attached to the outside of the roller 33 to form a protective layer. Its structural design takes into account the shape and size of the roller 33 to ensure that the rubber sleeve 5 can be firmly fixed on the roller 33 and will not fall off or deform during the rolling process.

[0059] The rubber sleeve 5 can be installed and removed by snap-fit ​​or sleeve connection, which ensures that the rubber sleeve 5 can be firmly fixed on the roller 33 and is easy to remove quickly.

[0060] In one embodiment, two adjacent rails 11 abut against each other; the connector 12 is sleeved on the outside of the two adjacent rails 11, the connector 12 is n-shaped and matches the rails 11, and the connector 12 and the rails 11 are connected by bolts.

[0061] When two adjacent rails 11 are laid, their ends, i.e., the openings at both ends of the rails 11, abut against each other. The connector 12 is designed in an n-shape, which matches the shape of the rails 11. The n-shape design not only facilitates the connector 12 to be sleeved on the outside of the two adjacent rails 11, but also ensures a tight fit between the connector 12 and the rails 11, reducing the risk of loosening or falling off due to the gap.

[0062] The connector 12 is connected to the rail 11 by bolts. Bolt connection is a common and reliable mechanical connection method, which has the advantages of high connection strength and easy disassembly. Fastening the connector 12 to the rail 11 by bolts can ensure a stable connection between adjacent rails 11 and prevent separation or dislocation caused by external forces.
