The control panel integrates a large number of control buttons, multi-function display screens, communication equipment, emergency brake devices and other core components, which are connected to various subsystems of the train through a complex wiring system.

[0004] The traditional control console has the following obvious defects: Excessive structural weight: Due to the combined structure of the fiberglass cover and metal frame, plus the weight of the traditional mechanical locks, the overall weight of the control panel is too heavy, which not only increases the energy consumption of the train operation, but also affects the dynamic balance performance of the train under high-speed operating conditions, posing a potential threat to driving safety.

DETAILED DESCRIPTION

[0021] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings here can be arranged and designed in various different configurations.

[0022] 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 invention claimed for protection, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] See also Figures 1 to 8 : A lightweight driver's cab comprises: an operating console, a left cabinet and a right cabinet, wherein the operating console is connected with the left cabinet and the right cabinet to form a U-shaped structure.

[0024] The operating table includes a lower platform area and an upper platform area, the lower platform area includes a lower platform frame 100 and a panel 300, the upper platform area includes an upper platform frame 200 and a panel 300, and the left cabinet and the right cabinet both include a side cabinet support frame assembly 400 and a door panel 500. The function of the frame structure is to provide equipment installation space and load-bearing, provide access to the equipment compartment, and provide installation of panels and door panels.

[0025] Figure 4The figure shows a preferred embodiment of the lower platform frame of the present invention. The structure includes a right support frame assembly and a left support frame assembly arranged symmetrically. Figure 4 For detailed explanation: The right support frame assembly and the left support frame assembly each include two groups of annular frame units and a plurality of vertical beams 160, each group of annular frame units includes a main frame unit and a secondary frame unit: The main frame unit includes a three-level annular support structure consisting of a top annular member 110, an intermediate annular member 102 and a bottom annular member 130, and the sub-frame unit includes an auxiliary support structure consisting of a top annular member 140 and a bottom annular member 150.

[0026] Furthermore, the top annular member 110, the middle annular member 120, the bottom annular member 130, the top annular member 140 and the bottom annular member 150 all adopt a hollow structure, which includes at least one cavity formed inside the corresponding annular member. The weight of the lower platform frame is reduced by a large-area weight reduction method, and the mass is reduced by about 30% while ensuring the load-bearing performance, thereby achieving lightweighting.

[0027] Furthermore, at least one weight-reducing hole 700 is provided on the vertical beam 160, and the weight can be further reduced through reasonable hole arrangement.

[0028] The connection method of the above-mentioned frame structure is as follows: the end corners of the top ring member 110 and the end corners of the bottom ring member 130 are welded through the vertical beam 160, the middle ring member 120 is arranged in the middle position between the top ring member 110 and the bottom ring member 130, and the end corners of the middle ring member 120 are welded to the vertical beam 160, the end corners of the top ring member 110 and the end corners of the bottom ring member 130 are welded through the vertical beam 160, and all welded joints are inspected by ultrasonic flaw detection to achieve longitudinal rigid connection and ensure the strength of the control panel structure.

[0029] Furthermore, mounting holes are provided in the connection area between the annular member and the vertical beam, which can be fixed by bolts. Through the synergistic effect of welding and bolt connection, a longitudinal rigid connection is achieved to ensure the overall strength and stability of the control panel structure, while providing the convenience of disassembly and maintenance.

[0030] The above implementation achieves a lightweight effect through the synergistic effect of the multi-stage annular frame and the vertical beams through structural optimization, while reducing the overall mass, ensuring the rigidity of the control cover and meeting the reliability requirements of the long-term use of the control console equipment.

[0031] In some preferred embodiments, the lower platen region further includes a power module auxiliary vertical beam 170 and a terminal cabinet auxiliary vertical beam 180. The power module auxiliary vertical beam 170 is connected between two auxiliary cross beams 190. The auxiliary cross beams 190 are disposed in the front side region of the top annular member 110 and the middle annular member 120. The terminal cabinet auxiliary vertical beam 180 is connected to the front side of the middle annular member 120 and the bottom annular member 130. The auxiliary vertical beams and the main frame vertical beams are arranged in a spaced and staggered manner to avoid stress concentration and ensure the stability and reliability of the structure.

[0032] A plurality of module mounting holes are uniformly distributed along the power module auxiliary vertical beam 170 and the terminal cabinet auxiliary vertical beam 180, arranged in a matrix, meeting the positioning and mounting requirements of the power module and the quick-release terminal box, which can not only improve the installation efficiency but also enhance the overall layout rationality of the equipment.

[0033] The design of the auxiliary vertical beams and the auxiliary cross beams is arranged according to the installation requirements of the actual functional modules, and their arrangement can be flexibly adjusted according to the specific application scenarios, not limited to the above specific settings.

[0034] On the basis of the above structure, a plurality of support vertical plates 600 are provided between the lower platen region and the upper platen region, realizing a reliable connection between the upper and lower platens and improving the overall structural stiffness. Combined with the attached Figure 5 A detailed description of the support vertical plates is as follows: The support vertical plate 600 includes a main body portion 610, and at least one weight-reducing waist hole 620 is provided on the main body portion 610. The distribution position of the weight-reducing waist hole 620 is set based on the stress distribution region of the main body portion 610 to ensure that the weight is reduced without affecting the structural strength.

[0035] Specifically, the distance from the outer edge of the weight-reducing waist hole 620 to the corresponding edge position of the main body portion 610 is 20 - 50 mm, preferably 20 mm. The aperture of the weight-reducing waist hole 620 is 50 - 80 mm, preferably 60 mm.

[0036] Through this size design, the weight-reducing waist hole 620 effectively reduces the material usage without weakening the structural strength.

[0037] In addition, a flanging 630 is formed at the edge of the main body portion 610, and the flanging is designed as a narrow flanging. By reducing the flanging size, the material usage is further reduced and the structural stability is maintained.

[0038] The thickness of the main body portion is 2.5 - 3.5 mm, preferably 3 mm. In this way, not only the weight distribution of the support vertical plate is optimized, but also its stability under load is ensured.

[0039] Through the above design, the support vertical plate 600 achieves a significant lightweight effect while ensuring the structural strength, which not only improves the overall structural performance of the support vertical plate, but also reduces the material cost and has high economy.

[0040] Figure 3 The figure shows a preferred embodiment of the connection between the upper platform frame 200 and the support vertical plate 600 of the present invention. The structure includes a plurality of connecting beams 210, which are installed between the upper and lower ends of adjacent support vertical plates 600 to form a hollow upper support frame structure. The connection between the connecting beams 210 and the support vertical plates is a combination of welding and bolting to ensure the stability of the structure and facilitate later maintenance.

[0041] The connecting beam 210 adopts an ergonomic arc design so that the operating area is located within the natural extension range of the operator's forearm, reducing shoulder and arm fatigue and improving operating comfort and work efficiency.

[0042] In a preferred embodiment, the hollow structure of the upper supporting skeleton structure is realized by forming at least one cavity inside the connecting beam 210 and the supporting vertical plate 600, thereby reducing the weight while ensuring the structural strength, thereby achieving the goal of lightweighting.

[0043] Figure 7 The following is a preferred embodiment of the side cabinet support frame of the present invention. Figure 7 For detailed explanation: The side cabinet support frame assembly 400 includes a top support member 410, a bottom support member 420, a support beam 440 and a vertical partition member 430. The top support member 410, the bottom support member 420 and the vertical partition member 430 adopt a hollow structure, which includes at least one cavity formed inside the corresponding support member. The weight of the side cabinet support frame is reduced by a large-area weight reduction method, and the mass is reduced by about 30% while ensuring the load-bearing performance, thereby achieving lightweighting.

[0044] The connection method of the above structure is: The end corners of the top supporting member 410 and the bottom supporting member 420 are welded through the supporting vertical beam 440, and the vertical partitioning members 430 are welded and installed between the top supporting member 410 and the bottom supporting member 420 at intervals to separate the internal space of the side cabinet.

[0045] The number and position of the vertical partition components 430 are distributed based on the shape, size and setting functions of the left cabinet and the right cabinet to meet different usage functions and installation requirements.

[0046] In a preferred embodiment, the number of the vertical partitioning components 430 is at least four, and weight-reducing holes are provided on the vertical partitioning components 430 to further reduce the weight.

[0047] Furthermore, mounting holes are provided in the connection area between the supporting member and the supporting beam, which can be fixed by bolts. The synergistic effect of welding and bolt connection not only realizes the longitudinal rigid connection and ensures the overall strength and stability of the side cabinet support frame, but also provides a convenient detachable maintenance function, thereby improving the practicability and maintainability of the structure.

[0048] On the basis of the above structure, the top ring member 110, the middle ring member 120, the bottom ring member 130, the top ring member 140 and the bottom ring member 150 are made of thin-walled plates, the top support member 410, the bottom support member 420 and the vertical partition member 430 are made of thin-walled plates, and the vertical beam 160, the connecting beam 210, the supporting vertical plate 600, the supporting vertical beam 440, the power module auxiliary vertical beam 170, the terminal cabinet auxiliary vertical beam 180 and the auxiliary horizontal beam 190 are also made of thin-walled plates.

[0049] In actual use, the cross-sectional shape of the thin-walled sheet can be optimized according to the specific use scenario, such as box-shaped, L-shaped, C-shaped and other lightweight structural forms with wall thickness significantly smaller than the cross-sectional size. This design minimizes the amount of material used while ensuring structural strength, achieving significant weight reduction.

[0050] In this embodiment, the thin-walled plate is made of aluminum alloy material, the plate thickness is reduced, the wall thickness of the thin-walled plate is 2-4 mm, and the wall thickness of the thin-walled plate is evenly distributed to ensure the consistency and stability of the structure. Through the thin-walled design of the plate, the overall mass is reduced by about 25%, achieving effective lightweighting. Preferably, the wall thickness of the thin-walled plate is 3 mm.

[0051] In this embodiment, the panel 300 and the door panel 500 are made of carbon fiber composite material, preferably carbon fiber honeycomb sandwich composite material.

[0052] Compared with traditional fiberglass materials, carbon fiber composite materials have higher specific strength and specific stiffness, while the material density is significantly reduced, further reducing the weight. This material selection not only improves the lightweight level of the structure, but also enhances the durability and fatigue resistance of the equipment.

[0053] Furthermore, the door panel 500 is connected to the corresponding supporting frame by a magnetic structure. A pair of magnetic sheets 800 of the magnetic structure are respectively installed on the inner wall surface of the door panel 500 and the contact surface of the corresponding supporting frame, so that the door panel 500 and the corresponding supporting frame can be detachably connected by magnetic adsorption.

[0054] By opening and closing the door panel magnetically, the use of traditional locks is eliminated and the number of parts is reduced. This not only simplifies the opening and closing operation of the door panel, improves the convenience and safety of use, but also reduces the weight.

[0055] Furthermore, the magnetic sheet 800 can be made of high-performance magnetic material to ensure that the door panel 500 has sufficient adsorption force in the closed state, thereby ensuring its stability and reliability. At the same time, the non-contact characteristics of the magnetic structure reduce mechanical wear, extend the service life of the door panel, and make the opening and closing operation of the door panel 500 smoother.

[0056] The beneficial effects of the lightweight driver's cab of the present invention are: The support frame of the control panel adopts thin-walled plates with cavity and weight-reducing holes to realize the hollow design of the whole frame, which makes the layout more compact, realizes lightweight while ensuring the bearing performance, and improves the utilization rate of the internal space. The panels and door panels are made of carbon fiber composite materials, which reduces the material density and significantly reduces the weight; The door panel eliminates the use of traditional locks, reduces the number of parts, further reduces weight, and at the same time reduces manufacturing costs and maintenance difficulties.

[0057] The above descriptions are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
