TECHNICAL FIELD
[0001] The present application relates to the field of rail vehicles and provides an installation assembly, an installation method, a vehicle body and a rail vehicle. BACKGROUND
[0002] Due to the requirements of installation structures of vehicle interiors, external devices and the like, a large number of installation assemblies are provided on the vehicle body of a rail vehicle, and some of the installation assemblies are required to be provided with threads for the installation of devices. Under the dual requirements of lightweight design of the vehicle body and improved installation precision of the devices, the adjustability of the installation assemblies is increasingly important.
[0003] Current rail vehicles need two major processes. The first process is the production of the steel (aluminum) structure of the vehicle body, that is, the conventional vehicle shell, which is similar to the body structure of an automobile. The second process is the installation of devices, interiors, cables and the like on the vehicle, such as transformers, seats, displays and the like. The above two processes are produced in two completely different workshops. The main reason is that the production of the vehicle shell requires welding, and the welding temperature is high and splashing may occur. If welding is performed in the second process, the devices, interiors and the like are easily damaged. Conventional screw seat pre-installation method: the screw seat is directly welded on the wallboard, and the position of the screw seat is fixed and cannot be adjusted. Moreover, the screw seat is welded by arc welding, which has a large amount of welding heat, and the wallboard is easily deformed, which affects the appearance of the wallboard. If the fixed point needs to be adjusted, the original fixed point needs to be cut off, and a new fixed point needs to be welded according to the positioning, which causes cross-operation problems between different processes, long overall operation time, and protection of the surrounding structure due to high welding temperature during welding.

[0032] like Figures 1 to 5 As shown, the present invention provides an installation assembly. The installation assembly includes: an installation plate 100 and an installation base 200.
[0033] The mounting plate 100 has a fixing surface 110 and a mounting cavity 120. The fixing surface 110 is suitable for fixing on the mounting surface of the vehicle body. The mounting seat 200 is disposed in the mounting cavity 120, and an adjustment gap 300 is formed between the mounting seat 200 and the mounting cavity 120 to adjust the position of the mounting seat 200 in the mounting cavity 120. A first mounting hole 210 is formed on the mounting seat 200.
[0034] Specifically, the mounting assembly consists of two parts: a mounting plate 100 and a mounting base 200. The mounting plate 100 has a mounting surface and a mounting cavity 120. The mounting surface is adapted to be fixed to the mounting surface of the vehicle body, thereby fixing the mounting plate 100 to a designated position on the vehicle body, such as a wall 400. The mounting cavity 120 is a receiving cavity formed on the mounting plate 100, used to place the mounting base 200 within the mounting cavity 120. There is an adjustment gap 300 between the mounting base 200 and the mounting cavity 120, meaning that the mounting base 200 can move within the mounting cavity 120 to adjust its mounting position. After the position is adjusted, the structure to be installed is then fixed to the mounting surface of the vehicle body through the first mounting hole 210.
[0035] Optionally, the mounting surface of the mounting plate 100 can be installed on the vehicle body by spot welding or bonding, which has little impact on the flatness of the vehicle body structure. This invention is particularly suitable for thin-walled vehicle exterior panels where aesthetics are important.
[0036] Optionally, the first mounting hole 210 can be an internally threaded hole, meaning the mounting base 200 is a screw seat made of carbon steel or stainless steel, with a rectangular or square shape and an internal thread in the center. The screw seat functions similarly to a nut, which also has an internal thread; therefore, in bolt connections, the screw seat and nut function identically. The screw seat and bolt can be used to install vehicle body equipment, such as passenger compartment doors and side windows, primarily suitable for equipment with a vertical mounting surface.
[0037] The present invention provides an installation component that can be pre-installed, and provides an embodiment of a specific installation method: The mounting plate 100 is spot-welded to the wall panel, resulting in low welding heat. A mounting cavity 120 is formed between the mounting plate 100 and the wall panel, into which the mounting base 200 is placed. Because there is an adjustment gap 300 between the mounting base 200 and the mounting cavity 120, the position of the mounting base 200 within the mounting cavity 120 can be adjusted. During equipment installation, the position of the mounting base 200 can be adjusted using bolts or screwdrivers according to the location of the equipment's fixing points. For example, it can be adjusted left-right, up-down, etc., providing adjustability to meet the adjustment needs of equipment installation. Furthermore, there is no need to remove the mounting base 200 for repeated welding, reducing overall assembly time.
[0038] This invention is a pre-installed structure that can be welded or bonded to the vehicle body before equipment installation. During equipment installation, it can be directly fastened by bolts from the side where the equipment is located.
[0039] Furthermore, this invention ensures the aesthetic appearance of thin-walled materials, especially those requiring no painting. For example, stainless steel vehicle sidewalls do not require painting or film application on their outer surface. Therefore, special attention must be paid to the impact of the construction process on the outer surface of the wall 400 during manufacturing. This is why the mounting plate 100 is spot-welded or bonded; arc welding would leave indelible marks on the outer surface of the wall panel, affecting its appearance. This invention achieves multi-directional adjustment of the mounting base 200 while protecting the outer surface of the sidewall.
[0040] Understandably, the mounting plate 100 can also be connected to the vehicle body by means of arc welding, laser welding, etc.
[0041] Taking the existing technology of car door installation as an example: the car door designer provides the specific location of the installation point on the car body to the body designer, who is responsible for designing the screw seat and welding it to the car body according to the installation point location. The screw seat needs to be welded to the car body in the first process, while the car door is installed in the second process. When the cumulative tolerance between the car body and the car door is large, and the car door cannot be installed, the position of the screw seat needs to be readjusted. It can be seen that compared with the problems of poor adjustability, easy deformation of the wall panel, and long process in the existing car body installation structure, this invention achieves the adjustability of the mounting seat 200 within the mounting cavity 120, meeting the adjustment requirements of equipment installation; it eliminates the need to remove the mounting seat 200 for repeated welding, reducing the overall assembly time.
[0042] This invention provides an installation assembly comprising: a mounting plate 100 and a mounting base 200. The mounting plate 100 has a fixing surface 110 and a mounting cavity 120. The fixing surface 110 is adapted to be fixed to a mounting surface of a vehicle body. The mounting base 200 is disposed within the mounting cavity 120, and an adjustment gap 300 is formed between the mounting base 200 and the mounting cavity 120 to adjust the position of the mounting base 200 within the mounting cavity 120. A first mounting hole 210 is formed on the mounting base 200. In this installation assembly, the mounting assembly is fixed to the mounting surface of the vehicle body via the fixing surface 110. The adjustment gap 300 between the mounting cavity 120 and the mounting base 200 allows adjustment of the position of the mounting base 200 within the mounting cavity 120. After the position is adjusted, the structure to be installed is then fixed to the mounting surface of the vehicle body through the first mounting hole 210. The present invention provides an installation component that enables the adjustability of the mounting base 200 within the mounting cavity 120, meeting the adjustment requirements for equipment installation; it eliminates the need to remove the mounting base 200 for repeated welding, reducing the overall assembly time.
[0043] In one embodiment of the present invention, the mounting plate 100 includes a first plate 101, a second plate 102, and a third plate 103. The first plate 101 is adapted to be fixed on the mounting surface of the vehicle body; a first end of the second plate 102 is connected to the first plate 101; the third plate 103 is adapted to be fixed on the mounting surface of the vehicle body and connected to the second end of the second plate 102, and the first plate 101, the second plate 102, the third plate 103, and the mounting surface of the vehicle body form a mounting cavity 120. Specifically, the mounting plate 100 is formed by welding, casting, or integrally molding a first plate 101, a second plate 102, and a third plate 103. The first plate 101 and the third plate 103 are located at the left and right ends of the second plate 102, respectively. The first plate 101 and the third plate 103 are fixed surfaces 110, which can be fixed to the vehicle body by spot welding or bonding. The second plate 102 is a structure that protrudes from the first plate 101 and the third plate 103, so that the first plate 101, the second plate 102, the third plate 103, and the mounting surface of the vehicle body surround a mounting cavity 120, and the mounting seat 200 is adjustable in position within the mounting cavity 120.
[0044] In one embodiment of the present invention, the first plate 101, the second plate 102 and the third plate 103 are all flat plate structures.
[0045] In one embodiment of the present invention, the mounting plate 100 further includes: a support plate 104 disposed at the third end of the second plate body 102 for supporting the mounting base 200; and an opening for inserting the mounting base 200 is formed at the fourth end of the second plate body 102 away from the support plate 104. Specifically, the support plate 104 is located at the bottom of the second plate body 102, and the top of the second plate body 102 is provided with an opening through which the mounting base 200 can be inserted, and the top opening can also be used to remove and replace the mounting base 200 when it is damaged; the support plate 104 at the bottom supports the mounting base 200 to prevent the mounting base 200 from falling off.
[0046] In one embodiment of the present invention, the mounting plate 100 further includes a first bending portion 105 and a second bending portion 106. The first bending portion 105 is connected between the first plate body 101 and the second plate body 102, so that the second plate body 102 protrudes from the surface of the first plate body 101; the second bending portion 106 is connected between the second plate body 102 and the third plate body 103, so that the second plate body 102 protrudes from the surface of the third plate body 103. Specifically, the mounting plate 100 can be an integral structure, formed by bending a sheet metal to form a mounting cavity 120, with flanges on both sides, and the flanges are connected to the vehicle body; the flanges are the first plate body 101 and the third plate body 103 in this embodiment, the first bending portion 105 and the second bending portion 106 are portions formed by bending a sheet metal, and form a second plate body 102 protruding from the surface of the first plate body 101 and the third plate body 103, thereby forming the mounting cavity 120.
[0047] Preferably, the first bending portion 105 and the second bending portion 106 can be formed by welding bending plates between the plates, thereby forming a mounting cavity 120 between the mounting plate 100 and the vehicle body mounting surface. Alternatively, the mounting cavity 120 can be processed by integrally bending the plate.
[0048] In one embodiment of the present invention, the mounting cavity 120 is a rectangular cavity; the mounting base 200 is a rectangular mounting base, and the length of the diagonal of the rectangular mounting base is greater than or equal to the length of the rectangular cavity. Through the dimensional design of the mounting base 200 and the mounting cavity 120, the mounting cavity 120 limits the rotation angle of the mounting base 200. During bolt installation, the mounting base 200 can only rotate a certain angle within the mounting cavity 120, which will not exceed 45°, thereby achieving the anti-rotation function of the mounting base 200 without the need for a separate anti-rotation washer.
[0049] In one embodiment of the present invention, the mounting base 200 includes a screw seat and a first mounting hole 210 that is a threaded hole. Specifically, the screw seat has an internally threaded hole for bolt engagement, thereby fixing the device to the vehicle body.
[0050] In one embodiment of the present invention, a second mounting hole 130 is formed on the mounting plate 100. Specifically, the second mounting hole 130 is provided on the back side of the mounting plate 100 for bolts to pass through. When the mounting base 200 is thick and the mounting bolts of the device do not need to penetrate the mounting base 200, the second mounting hole 130 may not be provided on the back side of the mounting plate 100.
[0051] The present invention also provides a method for installing an installation component, comprising the following steps: S1. The mounting plate is fixed to the mounting surface of the vehicle body by spot welding or bonding, and a mounting cavity with an opening at the top is formed between the mounting plate and the mounting surface; S2.

[0052] Specifically, the mounting component of the present invention adopts a pre-installation method. Before the equipment is installed, the mounting component is fixed to the wall panel. When the equipment needs to be installed, the position of the mounting base is adjustable and can be adjusted according to the equipment installation tolerance.
