Description

Technical Field

[0001] The present application relates to the technical field of rail vehicles, and particularly to a driver's cab cowl, a driver's cab and a rail vehicle. Background Art

[0002] The driver's cab of a rail vehicle generally includes a driver's cab cowl and a car body, which are manufactured separately and then assembled into one body. As one of the important components of a rail vehicle, the main function of the cowl is to control the front cowl through an opening and closing mechanism to realize the functions of opening and closing. When the cowl is opened, operations such as coupler reconnection, emergency rescue, and equipment maintenance can be carried out on the rail vehicle. When the cowl is closed, it can provide protection for the front car body and the driver during operation. In the prior art, the cowl of the driver's cab is usually of an integral structure. Especially in the application scenarios of some high-speed rail trains, in order to ensure a small air resistance, the driver's cab cowl is usually streamlined and manufactured as a whole, and is connected to the car body frame through brackets, connecting frames, etc.

[0003] During the high-speed operation of a rail train, it is easily impacted by foreign objects such as sand, gravel, and birds. Since the cowl is located at the front end of the train, the impact and damage it receives are particularly serious. When the cowl is severely damaged and cannot be used, in order to quickly repair the function, a new cowl needs to be replaced. Since the cowl is usually of an integral structure in the prior art, even if only a part is damaged, the whole cowl needs to be replaced. The cowl is connected to the car body through fasteners, and the overall volume is huge. When replacing, a large number of external equipment such as couplers, obstacle detectors, and opening and closing mechanisms need to be removed. After replacing the cowl, each item needs to be restored one by one. After restoration, the cowl needs to be painted together with the whole vehicle. The whole replacement process is time-consuming and the process is complex.

[0004] In addition, with the development of rail vehicle technology, the types of rail vehicles are becoming increasingly rich, and the shapes of cowls for different vehicle types will be different. Since the cowl is of an integral structure in the prior art, every time a vehicle type is changed, the cowl needs to be redesigned and a new mold needs to be opened, and the development cycle is very long and the cost is huge. Summary of the Invention

[0005] In order to solve one of the above technical defects, a driver's cab cowl, a driver's cab and a rail vehicle are provided in the embodiments of the present application.

[0006] According to the first aspect of the embodiments of the present application, a driver's cab cowl is provided, including:

[0007] The top middle plate of the cab hood, the top side plates of the cab hood, the front top plate of the cab hood, the side wall plates of the cab hood, the front headlamp cover plate of the cab hood, the side bottom fairing of the cab hood, the bottom fairing of the cab hood, the middle cover plate of the cab hood, and the windshield support plate, wherein the front of the cab hood is provided with the top middle plate of the cab hood, the front top plate facing the head, the windshield support plate, the middle cover plate of the cab hood, and the bottom fairing of the cab hood in sequence from back to front, from top to bottom; on both sides of the cab hood, the top side plates of the cab hood, the side wall plates of the cab hood, the front headlamp cover plate of the cab hood, and the side bottom fairing of the cab hood are provided in sequence from back to front, from top to bottom; each component cover plate of the cab hood is arranged on the outer side of the vehicle body frame, and adjacent cover plates are joined; each component cover plate of the cab hood is detachably connected to the vehicle body frame.

[0008] According to the second aspect of the embodiments of the present application, a cab is provided, including the cab hood as described above.

[0009] According to the third aspect of the embodiments of the present application, a rail vehicle is provided, including the cab as described above.

[0010] By using the cab hood provided in the embodiments of the present application, each cover plate constituting the cab hood can be separately designed, processed, and then assembled for use. When the cab hood is damaged during use, only the damaged cover plate can be replaced, greatly reducing the maintenance cost; in addition, when the vehicle model changes and the cab size changes, the applicable cover plates can be retained, and only the inapplicable cover plates need to be designed, developed, and replaced, which can improve the versatility of the cab hood in different projects, reduce the number of molds during new product development, and reduce the development, manufacturing cycle, and cost.

[0069] In order to make the technical solutions and advantages in the embodiments of the present application clearer and more understandable, the following further details the exemplary embodiments of the present application with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than an exhaustive list of all embodiments. It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0070] In the process of implementing the present application, the inventor found that in the field of rail vehicles, the driver's cab cowl in the prior art is of an integral structure. When the cowl is severely damaged and cannot be used during use, in order to quickly repair the function, it is necessary to replace the entire cowl with a new one. The cowl is connected to the vehicle body by fasteners, and the overall volume is huge. When replacing, a large number of external vehicle equipment such as couplers, obstacle detectors, and opening and closing mechanisms need to be removed. After replacing the cowl, each item needs to be restored one by one. After restoration, the cowl needs to be repainted together with the whole vehicle. The overall replacement process is time-consuming and the process is complex.

[0071] In addition, with the development of rail vehicle technology, the models of rail vehicles are becoming increasingly rich, and the shapes of cowls for different models will be different. Since the cowl in the prior art is of an integral structure, every time a new model is changed, it is necessary to re - design the cowl and re - mold it, and the development cycle is very long and the cost is huge.

[0072] In view of the above problems, in the embodiments of the present application, a driver's cab cowl is provided. In this embodiment, taking the application on a rail vehicle as an example, the implementation manner of the driver's cab cowl is specifically described as follows. Figures 1 - 44 As shown, in the embodiments of the present application, the longitudinal direction of the rail vehicle is called the longitudinal direction, the width direction of the vehicle is called the transverse direction, the height direction of the vehicle is called the vertical direction, the direction towards the running direction of the rail vehicle is called the front, the direction towards the opposite direction of the running direction of the rail vehicle is called the rear, the direction towards the outside of the driver's cab is called the outward, and the direction towards the inside of the driver's cab is called the inward.

[0073] As Figure 1 and Figure 2 shown, the driver's cab cowl provided by the embodiment of the present application is arranged on the outer side of the car body frame. The car body frame 104 serves as the main front-end bearing structure of the car body and is used to install the main components of the driver's cab. The rear end of the car body frame 104 is connected to the car body, and a window opening is provided in the front.

[0074] The driver's cab cowl includes a split-designed cowl middle top plate 141, cowl side top plates 142, cowl front top plate 143, cowl side wall plates 144, cowl front headlamp cover plate 145, cowl bottom side fairing 146, cowl bottom fairing 147, cowl middle cover plate 148, and windshield glass support plate 149. Among them, on the front of the cowl, the cowl middle top plate 141, cowl front top plate 143, windshield glass support plate 149, cowl middle cover plate 148, and cowl bottom fairing 147 are arranged in sequence from back to front, from top to bottom; on both sides of the cowl, the cowl side top plates 142, cowl side wall plates 144, cowl front headlamp cover plate 145, and cowl bottom side fairing 146 are symmetrically arranged in sequence from back to front, from top to bottom; each component cover plate of the cowl is arranged on the outer side of the car body frame, and adjacent cover plates are joined or detachably connected to each other; each component cover plate of the cowl is detachably connected to the car body frame.

[0075] Specifically, the cowl is a streamlined cover body formed by splicing and enclosing each component cover plate. The overall streamlined cover body design can reduce the air resistance encountered by the driver's cab when the train is running at high speed. After the cowl is damaged, only the damaged part of the cover plate can be replaced, and there is no need to replace the whole, effectively shortening the replacement cycle and saving time cost and economic cost.

[0076] In addition, multiple cover plates forming the cowl can be processed separately. Some relatively regular cover plates, such as the cowl middle top plate 141, cowl side top plates 142, cowl front top plate 143, cowl middle cover plate 148, cowl side wall plates 144, cowl bottom fairing 147, etc., can be processed from profiles, and only irregular cover plates such as the cowl front headlamp cover plate 145, cowl bottom side fairing 146, etc. need to be molded, reducing the amount and number of mold designs.

[0077] Finally, when the size and shape of the driver's cab need to be changed to meet actual requirements, only some cover plates can be replaced, and there is no need to re-design and mold the whole cover plate, effectively shortening the development cycle, saving time cost and R & D cost, and enabling new products to be quickly launched into the market. Several replacement schemes specifically used in the new project R & D center are shown in the following table:

[0078]

[0079] Further, a top cover top frame 1402 is provided at the top of the vehicle body frame 104. As Figure 38 and Figure 40 shown, the top cover top frame 1402 includes:

[0080] Top frame support brackets. There are multiple top frame support brackets, which are respectively arranged at the installation positions of the middle top cover plate 141, the side top cover plates 142 and the front top cover plate 143 of the top cover, and are used to support and fix the middle top cover plate 141, the side top cover plates 142 and the front top cover plate 143 of the top cover. The top end of the top cover top frame extends upward or obliquely upward. The lower end of the top frame support bracket is connected to the vehicle body frame 104, and C-shaped grooves are provided at the top end and the middle part of the top frame support bracket;

[0081] Top frame arch frames, which are arranged at the installation position of the front top cover plate 143. Both ends of the top frame arch frames are fixed on the vehicle body frame 104, and the middle part is an arched protrusion. C-shaped grooves are also provided on the top frame arch frames.

[0082] The top cover top frame 1402 is designed to facilitate the installation of the top cover plate of the top cover. With the support of the top cover top frame, there will be a space between the top cover plates such as the middle top cover plate 141, the side top cover plates 142 and the front top cover plate 143 of the top cover and the top of the vehicle body frame 104, which can be used to install some equipment or conduct wiring. In addition, since the vehicle body frame 104 is usually made of profiles and has a relatively square structure, while the overall streamline-shaped top cover requires that each cover plate needs to correspond to the curved surface structure required by its installation position, the top cover top frame is more suitable for installing cover plates with curved surface structures.

[0083] As Figure 40 and 41 shown, a specific implementation method for installing the middle top cover plate 141 is provided in the embodiment of the present application: The middle top cover plate 141 is a plate surface structure with a radian in the horizontal direction, and is arranged at the middle position above the vehicle body frame 104. The rear end of the middle top cover plate 141 (i.e., the end closer to the vehicle body in the longitudinal direction) is connected to the middle top cover plate of the vehicle body during the installation of the whole vehicle (connected, which can be connected to each other or just the edges of two adjacent components are close to or in contact. The same meaning applies to similar expressions in the following descriptions).

[0084] At the installation position of the middle top cover plate 141, a row of top frame support brackets are symmetrically fixed on both sides of the top of the vehicle body frame 104. The top frame support brackets in each row can be arranged at equal distances or the spacing can be set as required. Middle top cover plate installation points 1411 are provided on the periphery of the middle top cover plate 141. The middle top cover plate installation points 1411 on both sides of the middle top cover plate 141 are detachably connected to the C-shaped grooves on the top frame support brackets at the corresponding positions of the middle top cover plate installation points 1411 through fasteners 191.

[0085] Based on the above technical solution, as Figures 42 - 44 shown, in the embodiment of the present application, a specific implementation manner for installing the hood side top plate 142 is provided: There are two hood side top plates 142, symmetrically arranged on both sides of the above-mentioned hood middle top plate 141. The hood side top plates 142 also have a curved surface in the transverse direction. The upper side edges thereof are connected to the side edges of the hood middle top plate 141, and the lower side edges are fixed to the top edge of the vehicle body frame 104. Since the side edges of the hood middle top plate 141 are fixed to the top ends of the top frame support brackets and have a height difference from the top of the vehicle body frame 104, the installed hood side top plates 142 form a curved surface from top to bottom and form an arched structure together with the hood middle top plate 141.

[0086] Side plate mounting points 1421 are provided on both sides of the hood side top plate 142. The side plate mounting points 1421 on the upper side of the hood side top plate 142 are detachably connected to the C-shaped grooves in the middle parts of the top frame support brackets located on both sides of the hood middle top plate 141 through fasteners 191, and the side plate mounting points 1421 on the lower side of the hood side top plate 142 are detachably connected to the corresponding vehicle body frame C-shaped grooves 1041 through fasteners 191. It should be emphasized that the "middle part" mentioned in the embodiment of the present application, if not specifically emphasized, does not specifically refer to the exact middle position, but any suitable position between the two sides or ends of a certain component.

[0087] The side edges of the hood side top plate 142 are connected to the side plates of the vehicle body after the vehicle is assembled.

[0088] Based on the above technical solution, as Figures 36 - 40 shown, in the embodiment of the present application, a specific implementation manner for installing the hood front top plate 143 is provided: Above the window of the vehicle body frame 104, the space from the upper end of the window to the front end of the hood middle top plate 141 is the installation position of the hood front top plate 143. On both sides of the installation position of the hood front top plate 143, top frame arched brackets are symmetrically and longitudinally arranged, and one top frame support bracket is arranged one after the other at the middle position in the transverse direction of the two top frame arched brackets.

[0089] The rear end of the front top plate 143 of the cowl is joined to the front end of the middle top plate 141 of the cowl. The front end of the front top plate 143 of the cowl is provided with a second mounting point 1432 of the front top plate, and the rear end of the front top plate 143 of the cowl is provided with a first mounting point 1431 of the front top plate. Both the first mounting point 1431 of the front top plate and the second mounting point 1432 of the front top plate are integrated with a connection code 1433 of the front top plate. The first mounting point 1431 of the front top plate connects the connection code 1433 of the front top plate to a C-shaped groove at a corresponding position on the vehicle body frame 104 through a fastener 191 via a front top plate connection bracket 1434. The second mounting point of the front top plate connects the connection code 1433 of the front top plate to a C-shaped groove at a corresponding position on the top frame 1402 of the cowl through a fastener 191 via a front top plate connection bracket 1434.

[0090] The position of the front top plate 143 of the cowl is the position where the cowl transitions from the connection with the vehicle body to the front cover plate. After installation, it is a transition curved panel with a higher rear end (joined to the middle top plate of the cowl) and a lower front end, and it is part of the overall streamlined shape of the cowl.

[0091] Based on the above technical solution, as Figures 2 - 6 shown, in the embodiment of the present application, a specific implementation method for installing the windshield glass support plate 149 is provided: The windshield glass support plate 149 is a frame-shaped structure adapted to the window opening, and is provided at the window opening opened on the vehicle body frame 104, and its upper end is joined to the front top plate 143 of the cowl. Mounting points are provided on the periphery of the windshield glass support plate 149. Among them, the top mounting point 1491 of the windshield support plate located at the top of the windshield glass support plate 149 and the bottom mounting point 1492 of the windshield support plate located at the bottom of the windshield glass support plate 149 are connected to the C-shaped groove 1041 of the vehicle body frame at the corresponding position through a windshield connection plate 1494 and a fastener 191. Windshield connection brackets 1495 are integrated at the two-side mounting points 1493 on the inner surface of the windshield glass support plate 149, and the windshield connection brackets 1495 are connected to the C-shaped groove 1041 of the vehicle body frame at the corresponding position through a windshield connection plate 1494 and a fastener 191. Among them, the windshield connection plate 1494 at the bottom mounting point 1492 of the windshield support plate is a horizontal straight plate structure, the windshield connection plate 1494 at the top mounting point 1491 of the windshield support plate is a bent plate adapted to the structure where the top of the vehicle body frame 104 bends down to the front face, the windshield connection bracket 1495 is a U-shaped structure with the opening integrated at the two-side mounting points 1493 of the windshield support plate, and the windshield connection plate 1494 at the two-side mounting points 1493 of the windshield support plate is a 90° bent plate structure.

[0092] Furthermore, the contact surface between the windshield glass support plate 149 and the vehicle body frame 104 is further fastened through a sealant 192. Further sealing with the sealant can prevent the oncoming airflow from entering the driver's cab through the gaps during high-speed operation.

[0093] Based on the above technical solution, as Figures 19 - 25 shown, in the embodiment of the present application, a specific implementation manner for installing the middle cover plate 148 of the head cover is provided: the middle cover plate 148 of the head cover is arranged on the lower side of the window of the vehicle body frame 104, its top is connected to the lower end of the windshield support plate 149, and its bottom end is bent towards the inside of the vehicle body frame 104; installation points are provided around the middle cover plate 148 of the head cover.

[0094] The first middle cover plate installation point 1481 located at the top of the middle cover plate 148 of the head cover is connected to the windshield connection bracket 1495 provided at the corresponding position on the windshield support plate 149 through the fastener 191 and the middle cover plate connection bracket 1484. Here, the middle cover plate connection bracket 1484 is a U-shaped structure with the opening integrated at the first middle cover plate installation point 1481, and the windshield connection bracket 1495 is a stepped structure adapted to the height difference of the connection surfaces of the middle cover plate 148 of the head cover and the windshield support plate 149.

[0095] The second middle cover plate installation points 1482 located on both sides of the middle cover plate 148 of the head cover are connected to the headlight cover plate connection code 1457 provided at the corresponding position on the headlight cover plate 145 of the head cover through the fastener 191 and the middle cover plate connection bracket 1484; here, the middle cover plate connection bracket 1484 is a U-shaped structure with the opening integrated at the second middle cover plate installation point 1482, and the headlight cover plate connection code 1457 is a stepped structure adapted to the connection flange of the middle cover plate 148 of the head cover and the headlight cover plate 145 of the head cover.

[0096] The third middle cover plate installation point 1483 located at the bottom end of the middle cover plate 148 of the head cover that is bent inward is connected to the C-shaped groove 1041 of the corresponding vehicle body frame through the fastener 191 and the middle cover plate connection bracket 1484. Here, the middle cover plate connection bracket 1484 is an arched structure with one end connected to the third middle cover plate installation point 1483 and the other end connected to the C-shaped groove 1041 of the vehicle body frame, and the arched structure can better buffer vibration.

[0097] Based on the above technical solution, as Figures 7 - 18As shown in the figure, a specific implementation method for installing the front headlamp cover plate 145 is provided in the embodiment of the present application: There are two front headlamp cover plates 145, symmetrically arranged on both sides of the middle cover plate 148 of the head. Each front headlamp cover plate 145 includes a vertical side plate assembled on the side of the vehicle body frame 104 and a front panel assembled on the front of the vehicle body frame 104. The vertical side plate of the front headlamp cover plate 145 is bent in the middle at its front end in the obliquely upward direction to form the front panel of the front headlamp cover plate 145. An opening matching the shape and size of the vehicle lamp is provided on the front panel of the front headlamp cover plate 145.
