Description

Technical Field

[0001] This utility model relates to the field of rail transit technology, and in particular to a flexible self-locking cover plate. Background Technology

[0002] With the rapid development of rail transit technology, while high-speed trains continue to increase in speed, they are evolving towards modularization and customization. Currently, train control panels have the following problems:

[0003] First, the overall weight is too large: the current control panel adopts a traditional metal frame structure, combined with a fiberglass cover and mechanical locks, which results in an excessive overall weight of the train. This not only increases the energy consumption of the train during operation, but also makes it difficult to maintain dynamic balance at high speeds.

[0004] Second, the operation is complex and cumbersome: the current locking system of the control panel still uses traditional manual operation methods such as mechanical keys, which increases the driver's operating burden and also increases the complexity of inspection and maintenance. Utility Model Content

[0005] The main technical problem solved by this utility model is to provide a flexible self-locking cover. Through the triple optimization of integrated carbon fiber cover, gas spring support and magnetic lock, the overall control panel is made lightweight, while also having the advantages of high strength, easy operation and low cost and long service life, making it suitable for harsh vehicle environments.

[0006] To solve the above-mentioned technical problems, the present invention provides a flexible self-locking cover plate, comprising: a stacked main body, a resettable support structure, and a self-locking structure.

[0007] The stacked main body includes a substrate and a flexible covering layer and a connecting thin plate connected to the upper and lower sides of the substrate.

[0012] In a preferred embodiment of the present invention, the flexible covering layer is a composite leather layer, including an intermediate foam layer and a polyurethane surface layer and a flame-retardant adhesive underlayer connected to both sides of the intermediate foam layer.

[0013] In a preferred embodiment of this utility model, the thickness of the flexible covering layer is 2-6 mm.

[0014] In a preferred embodiment of this utility model, the fitting gap between the connecting thin plate and the substrate is 1-3 mm.

[0015] In a preferred embodiment of this utility model, the corners of the flexible covering layer are hidden within the mating gap between the connecting thin plate and the substrate.

[0016] In a preferred embodiment of this utility model, structural adhesive is also coated in the gap between the connecting sheet and the substrate to achieve bonding and fixing of the connecting sheet and the substrate.

[0030] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0031] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0032] This utility model relates to a preferred embodiment of a flexible self-locking cover.

[0033] Please see Figures 1 to 4 The flexible self-locking cover plate includes: a stacked main body 1, which is connected to the upper surface of the control panel support frame 2, and a resettable support structure 3 and a self-locking structure 4 are connected to the stacked main body 1.

[0034] In detail, the first is the laminated main body 1, which includes a substrate 11 and a flexible covering layer 12 and a connecting thin plate 13 connected to the upper and lower sides of the substrate 11:

[0035] The flexible covering layer 12 is tightly bonded to the upper surface of the substrate 11 by hot pressing, forming a tightly fitted seamless covering structure; the connecting plate 13 forms a 1-3mm gap fit with the substrate 11, and the connecting plate 13 is used to fit or be close to the control panel support frame 2.

[0036] Furthermore, the edges and corners of the flexible covering layer 12 are hidden within the mating gap 14 between the connecting thin plate 13 and the substrate 11. Structural adhesive is also coated within the mating gap 14 between the connecting thin plate 13 and the substrate 11 to achieve bonding and fixation between the connecting thin plate 13 and the substrate 11. This ensures the aesthetics of the edges of the covering layer and enhances the connection strength and integrity of the stacked main body through the bonding effect of the structural adhesive.

[0037] In one exemplary embodiment, the substrate 11 has a thickness of 6-8 mm, the flexible covering layer 12 has a thickness of 2-6 mm, and the connecting plate 13 has a thickness of 1-3 mm.

[0038] Both the substrate 11 and the connecting sheet 13 include a carbon fiber skin surface layer and a PVC foam board filling core layer disposed within the carbon fiber skin surface layer, which can reduce the overall weight of the cover plate while ensuring strength. The carbon fiber skin provides excellent strength and stiffness, while the PVC foam core layer has good compressive strength and weight reduction effect. Together, they make the structure both high-strength and lightweight.

[0039] The flexible covering layer 12 is a composite leather layer, which not only ensures a soft touch effect but also enhances aesthetics, reduces the weight of the cover, and achieves lightweighting of the cover, thus playing a positive role in the overall lightweighting of the control panel.

[0040] Preferably, the composite leather layer includes an intermediate foam layer and a polyurethane surface layer and a flame-retardant adhesive underlayer connected to both sides of the intermediate foam layer.

[0041] By combining the substrate with the composite leather layer, the cover plate is integrated, which significantly reduces the overall density of the cover plate and greatly reduces its weight compared to traditional metal covers, thus achieving overall lightweighting of the control panel.

[0042] Secondly, there is a resettable support structure 3, which is installed at the far end of the stacked main body 1 to realize the opening and closing connection between the stacked main body 1 and the control panel support frame 2.

[0043] The resettable support structure 3 includes a gas spring 31, a first connector 32, and a second connector 33. The first connector 32 is installed on the far end of the inner wall of the stacked main body 1, and the second connector 33 is installed on the control panel support frame 3. The two ends of the gas spring 31 are respectively hinged to the first connector 32 and the second connector 33 to achieve resettable support of the stacked main body 1 relative to the control panel support frame 2.

[0044] When in the open state: the gas spring 31 provides support force to counteract the weight of the stacked main body 1; when in the closed state, the pre-compression stroke of the gas spring 31 ensures that the stacked main body 1 fits tightly with the support frame; when subjected to external opening force, the gas spring 31 automatically unlocks and pushes the stacked main body 1 to the maximum opening position.

[0045] The gas spring reset support structure described above ensures stable opening and closing support performance. At the same time, compared with traditional support structures, the gas spring can significantly reduce the overall weight while providing sufficient support force.

[0046] Furthermore, there is a self-locking structure 4, which is installed at the near end of the stacked main body 1 and can provide a self-locking force in the closed state to achieve a reliable locking connection between the stacked main body 1 and the control panel support frame 2.

[0047] The self-locking structure 4 includes a suction plate 41 and a magnetic suction piece 42. The suction plate 41 is locked to the near end of the inner wall of the stacked main body 1, and the magnetic suction piece 42 is locked to the position on the control panel support frame 2 corresponding to the suction plate 41.

[0048] The magnetic self-locking structure enables quick locking and unlocking, reducing the complexity of driving and maintenance. In addition, the ultra-thin magnetic structure greatly reduces the overall weight, saves installation space, and is suitable for compact layouts.

[0049] The beneficial effects of this utility model of flexible self-locking cover plate are:

[0050] The cover is integrated and has good strength. The base plate is made of carbon fiber material wrapped with PVC foam board core layer and composite leather wrapped on the surface of the base plate. The bottom is connected with a thin plate to increase the proportion of composite materials and ensure the overall appearance of the cover plate. At the same time, it greatly reduces the weight compared with traditional metal covers, which can achieve the overall lightweighting of the control panel.

[0051] It can achieve stable opening and closing support, and compared with traditional support structures, gas springs can significantly reduce the overall weight while providing sufficient support force.

[0052] By eliminating traditional mechanical locks and adopting a magnetic opening and closing mechanism, the number of parts is reduced, the overall weight is further reduced, and the complexity of driving and maintenance is also reduced, thus lowering costs.

[0053] 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 using the content of this utility model specification, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
