Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of railway vehicles, and particularly relates to a top cover and a vehicle. BACKGROUND

[0002] In the past ten years or so, in order to avoid the scattering or rain of the goods loaded in the open carriages of railway freight transport, a type of open carriage starts to use a roller shutter type top cover to cover the opening of the carriage. Two top covers are arranged on the top of the open carriage and are sequentially distributed along the length direction of the carriage. The top covers run along the two sides of the carriage width direction on the slide rails arranged on the top edges of the side walls on both sides of the open carriage.

[0003] In the specific implementation, the applicant finds that due to the very long length of the top cover, which is formed by many relatively narrow hinged plates hinged like a roller shutter, there is a certain gap between the hinged plates, and the top cover may have a certain deformation. Therefore, when the top cover of the vehicle is opened or closed, the middle part of the top cover along the length direction of the carriage often swings left and right, causing the side wall of the top cover to slide along the inner side of the slide rail, which has a large frictional resistance and emits a sharp and loud noise, affecting the working environment. SUMMARY

[0004] To solve the technical problems of the large frictional resistance and loud noise caused by the scraping of the side wall of the top cover on the slide rail during the opening or closing of the top cover, the present application provides a top cover and a vehicle.

[0005] In the first aspect of the present application, a top cover is provided for slidingly mounting on two oppositely arranged slide rails of an open carriage, comprising:

[0006] a cover body;

[0007] a sliding unit corresponding to the slide rail, the two sliding units being connected to the two sides of the cover body along the width direction of the carriage, the sliding unit comprising a guide assembly and a limiting assembly arranged at intervals along the extension direction of the slide rail, and the limiting assembly comprising a limiting wheel mounted on the cover body, wherein:

[0008] along the width direction of the carriage, the tread of the limiting wheel has a smaller distance from the corresponding slide rail than the distance between the side of the cover body and the slide rail, so that the limiting wheel and the inner side of the slide rail are rollingly matched during the sliding opening or closing of the cover body along the slide rail.

[0009] In some embodiments, the cover body is provided with a notch on each of the two sides along the width direction of the carriage, one side of the guide assembly is located in the corresponding notch, and the other side of the guide assembly extends out of the corresponding notch and is matched with the corresponding slide rail.

[0010] The limiting assembly is connected to the cover body and located in the notch.

[0011] In some embodiments, the cover is provided with receiving grooves, the limiting wheels are located in the corresponding receiving grooves, and the tread surfaces of the limiting wheels extend out of the receiving grooves.

[0012] In some embodiments, the limiting assembly is located close to the guiding assembly along the extension direction of the slide rails.

[0013] In some embodiments, the guiding assembly is provided with a plurality of limiting assemblies, and the limiting assemblies and the guiding assembly are spaced apart.

[0014] In some embodiments, the slide rail comprises a first slide part and a second slide part arranged in sequence from top to bottom, and the first slide part extends out of the second slide part along both sides of the width direction of the vehicle cabin.

[0015] In the case that the top cover closes the vehicle cabin, the lower end of the limiting wheel extends downwardly out of the first slide part.

[0016] In some embodiments, the limiting assembly further comprises a bracket, the bracket is provided with a clamping groove and a mounting groove, the side portion of the cover extends into the clamping groove, and the limiting wheel is mounted in the mounting groove.

[0017] In some embodiments, the bracket and the cover plate are connected by welding or threaded fasteners.

[0018] In some embodiments, the bracket comprises a clamping plate, a clamping arm, a connecting plate, and a reinforcing plate, the clamping plate and the clamping arm are both provided with two, and the clamping plate and the clamping arm are located on the opposite sides of the connecting plate, the two clamping plates are connected to the connecting plate to form the clamping groove, the two clamping arms are connected to the connecting plate to form the mounting groove, and the reinforcing plate is connected to the clamping plate and the connecting plate.

[0019] In the second aspect of the present application, a vehicle is provided, comprising a vehicle cabin with an opening and a top cover of the first aspect, the vehicle cabin is provided with two slide rails, the top cover is slidably arranged on the two slide rails to open or close the opening, the guiding wheels are rolling fitted on the corresponding slide rails, and the tread surfaces of the limiting wheels are rolling fitted on the inner side surfaces of the slide rails.

[0020] According to the top cover provided by the embodiment of the present application, the two sides of the top cover along the width direction of the carriage are provided with limiting assemblies, and the distance between the tread of the limiting wheel and the slide rail is smaller than the distance between the side of the cover body and the slide rail along the width direction of the carriage. Therefore, when the top cover is laterally displaced in the middle part along the extension direction of the rail, the tread of the limiting wheel is always in rolling contact with the inner side of the slide rail, and the rolling frictional resistance is small. In this way, the resistance during the opening and closing process of the top cover can be reduced, the wear of the cover body is reduced, and sharp and harsh noise is not generated, and the working environment is improved.

[0021] Since the limiting assembly and the guide assembly are arranged at intervals, the limiting wheel can be directly installed on the existing top cover structure, without the need to eliminate the original guide assembly, and without the need to transform the smaller guide assembly. The problems of small operation space, inconvenient operation and difficult transformation are solved, and the cost is saved. BRIEF DESCRIPTION OF DRAWINGS

[0032] In order to make the skilled person in the art to which the present application belongs more clearly understand the present application, the technical solutions in the embodiments of the present application will be described clearly and completely below in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by the person of ordinary skill in the art without creative labor fall within the scope of protection of the present application.

[0033] The first aspect embodiment of the present application provides a top cover, which is suitable for an open carriage, is slidingly installed on two oppositely arranged slide rails of the carriage, and has small frictional resistance and low noise when the top cover is opened and closed relative to the slide rails of the open carriage.

[0034] The present application will be described below in combination with the drawings and with reference to specific embodiments:

[0035] Please refer to Figure 1 and Figure 2 The top cover 100 provided by the present application includes a cover body 130 and a sliding unit.

[0036] The cover body 130 is the main structure of the top cover 100 and includes a plurality of covering units, which are sequentially hinged along the extension direction of the slide rails 210 through first hinge shafts 134. The two ends of the first hinge shaft 134 are respectively rotationally connected with two guide units. The covering unit includes two covering plates 131, which are hinged through a second hinge shaft 135. The two ends of the second hinge shaft 135 contact the top surfaces of the two slide rails 210. In the process of slidingly closing the cover body 130 relative to the slide rails 210, the first hinge shaft 134 slides under the guiding action of the sliding unit, and the plurality of first hinge shafts 134 gradually approach each other. The second hinge shaft 135 gradually rises under the tilting action of the covering plate 131, so as to realize the folding of the cover body 130 and open the carriage 200. Conversely, the plurality of first hinge shafts 134 gradually move away from each other, and the second hinge shaft 135 gradually lowers in height until it is supported by the slide rails 210, so as to realize the unfolding of the cover body 130 and close the carriage 200.

[0037] The sliding unit corresponds to the slide rail 210 one by one, and the two sliding units are connected to the two sides of the cover body 130 along the width direction of the carriage 200. Please refer to Figure 2 The sliding unit includes a guide assembly 120 and a limiting assembly 110, which are spaced apart along the extension direction of the slide rail 210. The guide assembly 120 is used to provide the guiding action of the sliding of the cover body 130 relative to the slide rail 210. Please refer to Figure 3The limiting assembly 110 includes a limiting wheel 112 mounted on the cover 130. In the width direction of the compartment 200, the tread of the limiting wheel 112 is spaced apart from the corresponding slide rail 210 by a distance smaller than the distance between the side of the cover 130 and the slide rail 210. In other words, the distance between the tread of the limiting wheel 112 and the inner side of the corresponding slide rail 210 is smaller than the distance between the side of the cover 130 and the inner side of the corresponding slide rail. In the process of opening or closing the compartment 200 by sliding the cover 130 along the slide rail 210, even if the cover 130 is shaken left or right at the middle of the compartment 200, for example, the cover 130 is shifted to the left, the limiting wheel 112 on the left side will roll with the inner side of the slide rail 210 on the left side, the cover 130 is shifted to the right, the limiting wheel 112 on the right side will roll with the inner side of the slide rail 210 on the right side, and the side of the cover 130 will not be in contact with the slide rail 210, thereby reducing the resistance in the process of opening and closing the roof 100, reducing the wear of the cover 130, and not producing sharp and harsh noise, thereby improving the working environment.

[0038] Since the limiting assembly 110 is spaced apart from the guide assembly 120, that is, the limiting wheel 112 is separately mounted outside the guide assembly 120, the existing roof 100 structure can be directly added with the limiting wheel 112, without the need to eliminate the original guide assembly 120, and without the need to modify the smaller guide assembly 120, thereby solving the problems of small operation space, inconvenient operation, and difficult modification, and saving costs.

[0039] In some embodiments, referring to Figure 2 The cover 130 is provided with a notch 132, that is, an avoiding groove, on both sides in the width direction of the compartment 200. One side of the guide assembly 120 is located in the corresponding notch 132, and the other side extends out of the corresponding notch 132 to cooperate with the corresponding slide rail 210, thereby achieving the arrangement of the guide assembly 120. Figure 4 In other embodiments, referring to

[0040] Referring to Figure 2 In the case where the cover 130 is provided with the notch 132, the limiting assembly 110 is connected to the cover 130 and located at the bottom of the notch 132, so that the limiting assembly 110 can be installed in the notch 132 accommodating the guide assembly 120, without the need to additionally open an opening, thereby making the modification more convenient. At the same time, the width of the cover 130 does not need to be narrowed, thereby improving the covering effect of the cover 130. In other embodiments, the limiting assembly 110 can be additionally arranged on the cover 130 by additionally opening a notch 132 on the cover 130.

[0041] In some embodiments, referring to Figure 3The cover 130 is provided with a receiving groove located at the bottom of the gap 132, i.e. the groove bottom of the avoiding groove, and the limiting wheel 112 is located in the corresponding receiving groove and the tread of the limiting wheel 112 extends out of the receiving groove, so that the arrangement space of the limiting wheel 112 is increased, the limiting wheel 112 with a large diameter size is selected, the strength of the limiting wheel 112 is improved, and the service life is prolonged.

[0042] In some embodiments, the limiting assembly 110 is close to the guide assembly 120 along the extension direction of the slide rail 210.

[0043] During the opening and closing of the cover 130, the height of the first hinge shaft 134 is constant, the height of the second hinge shaft 135 changes, and the covering plate 131 switches between tilting and horizontal. Since the guide assembly 120 is connected with the first hinge shaft 134, along the length direction of the carriage 200, the end of the covering plate 131 close to the guide assembly 120 has a constant height during the opening and closing of the cover, and the limiting wheel 112 is close to the guide assembly 120, i.e. close to the side with a constant height during the opening and closing of the cover. Thus, the action time of the limiting wheel 112 and the slide rail 210 can be prolonged, and the anti-wear effect of the cover 130 is improved. In other embodiments, the limiting assembly 110 is close to the second hinge shaft 135 to improve the anti-wear effect of the cover 130 to some extent.

[0044] In some embodiments, referring to Figure 2 , the guide assembly 120 is provided with multiple limiting assemblies 110, and the limiting assemblies 110 and the guide assembly 120 are arranged at intervals to improve the anti-wear effect of the cover 130 at various positions along the length direction of the carriage 200.

[0045] In some embodiments, the slide rail 210 includes a first sliding part 211 and a second sliding part 212 arranged in sequence from top to bottom, and the first sliding part 211 extends out of the second sliding part 212 along both sides of the width direction of the carriage 200. In the case that the roof 100 closes the carriage 200, the lower end of the limiting wheel 112 extends downward out of the first sliding part 211 to prolong the action time of the limiting wheel 112 and the inner side surface of the slide rail 210 during the opening and closing of the cover 130, and improve the anti-wear effect of the cover 130.

[0046] In some embodiments, referring to Figure 4 and Figure 5 , the limiting assembly 110 further includes a bracket 111 provided with a clamping groove and a mounting groove, the side of the cover 130, i.e. the covering plate 131, extends into the clamping groove, and the limiting wheel 112 is mounted in the mounting groove to realize the connection between the limiting wheel 112 and the cover 130. In some embodiments, the bracket 111 is connected with the cover by welding or threaded connection.

[0047] In some embodiments, please refer to Figure 4 The bracket 111 includes clamping plates 1111, clamping arms 1114, a connecting plate 1112, and a reinforcing plate 1113. The clamping plates 1111 and the clamping arms 1114 are both provided with two, and the clamping plates 1111 and the clamping arms 1114 are located on the opposite sides of the connecting plate 1112. The two clamping plates 1111 are spaced apart and connected to the connecting plate 1112 to form a clamping groove. The two clamping arms 1114 are spaced apart and connected to the connecting plate 1112 to form a mounting groove. The reinforcing plate 1113 is connected to the clamping plate 1111 and the connecting plate 1112 to improve the connection strength of the clamping plate 1111 and the connecting plate 1112.

[0048] The guide assembly 120 serves as a guide structure, please refer to Figure 6 , including a guide bracket 121 and a guide wheel 122. The guide bracket 121 is provided with a through groove extending along the extension direction of the slide rail 210. The guide wheel 122 is installed in the through groove. The guide wheel 122 is rollingly fitted to the first sliding part 211 of the slide rail 210. The first sliding part 211 is located in the through groove. The upper end of the second sliding part 212 is located in the through groove, and the lower end extends out of the through groove. The guide shaft of the guide wheel 122 is connected with the first hinge shaft 134.

[0049] Based on the same technical concept of the first aspect, the second embodiment of the present application provides a vehicle, please refer to Figure 7 , including a vehicle cabin 200 with an opening and the roof 100 of any one of the embodiments of the first aspect. The vehicle cabin 200 is provided with two slide rails 210. The roof 100 is slidingly arranged on the two slide rails 210 to open or close the opening. The guide wheel 122 is rollingly fitted to the corresponding slide rail 210. The tread of the limiting wheel 112 is rollingly fitted to the inner side surface of the slide rail 210.

[0050] In some embodiments, the roof 100 is provided with two. The two roofs 100 are oppositely arranged along the length direction of the vehicle cabin 200. The two roofs 100 are provided with a sliding seat 140 on the side close to each other. In the case that the opening and closing mechanism on the ground abuts against the opening and closing rod 150 on the sliding seat 140, the vehicle moves along the track. The roof 100 is folded or unfolded to open or close the opening of the vehicle cabin 200.

[0051] The vehicle with the roof 100 described above in the process of opening or closing. Since the roof 100 is provided with a plurality of limiting assemblies 110 spaced apart on both sides along the width direction of the vehicle cabin 200, even if the middle part of the roof 100 along the length direction shakes left and right, the limiting assemblies 110 can still prevent the covering plate 131 from slidingly rubbing against the inner side surface of the slide rail 210. The limiting assemblies 110 are directly installed on the basis of the original roof 100, which is convenient to implement, simple in structure, and strong in practicality.
