Machinery, parts and equipment all adopt conventional models in the prior art, and the circuit connection adopts the conventional connection method in the prior art, which will not be described in detail here.

[0041] The following is combined with Figure 1-5 , further details of this application are given.

[0042] In a first aspect, the present application provides a rail vehicle deflector assembly structure, which adopts the following technical solution:

[0043] Reference Figure 1 A rail vehicle deflector structure includes a deflector plate 1, an outer guard plate 2 and an inner baffle plate 3. The outer guard plate 2 and the inner baffle plate 3 are detachably installed on the front and rear surfaces of the deflector plate 1 respectively. The deflector plate 1, the outer guard plate 2 and the inner baffle plate 3 are composed of composite material sandwich layers such as halogen-free flame-retardant epoxy prepreg and flame-retardant foam core material, and have good stiffness, strength, impact resistance, fatigue resistance and fire resistance.

[0044] The upper and lower ends of the inner baffle 3 are detachably connected with a partition 4 and a connecting hinge 5, respectively. By installing the partition 4, it is convenient for the air deflector to be connected to the corresponding parts. The partition 4 is made of rubber material, and can be connected to the corresponding hinged parts through the connecting hinge 5, so as to facilitate the rotation of the air deflector. In addition, an annular sealing strip is installed between the partition 4 and the inner baffle 3, and between the connecting hinge 5 and the inner baffle 3 to ensure the sealing of the connection between the partition 4, the connecting hinge 5 and the corresponding parts and the inner baffle 3, so as to avoid leakage of the air deflector. At the same time, the strength of the air deflector is improved by the coordination between the air deflector 1, the outer guard plate 2 and the inner baffle 3.

[0045] Reference Figure 2 and Figure 3At least two installation grooves 11 are evenly spaced on one side of the guide plate 1 close to the outer guard plate 2, and a first through hole 12 is formed through the bottom of the installation groove 11. At least two grooves 31 are formed on the side of the inner baffle plate 3 away from the guide plate 1, and a second through hole 32 is formed through the bottom of the groove 31. The second through hole 32 is connected to the first through hole 12, and the first through hole 12 and the second through hole 32 are connected to form an installation channel connecting the bottom of the installation groove 11 and the bottom of the groove 31. A connecting column 6 is installed in the installation channel of the guide plate 1, and one end of the connecting column 6 is integrally formed with an external thread, and the connecting column 6 slides freely in the installation channel. The connecting column 6 is sleeved with a first gasket 13 and a second gasket 33 on the side, and the first gasket 13 is located at the bottom of the installation groove 11, and the second gasket 33 is located at the bottom of the groove 31. The other end of the connecting column 6 extends to both sides of the connecting column 6 to form an integral limited retaining edge 61, and the limited retaining edge 61 is located in the installation groove 11. During the installation process, one end of the connecting column 6 with an external thread penetrates from the installation groove 11, passes through the first through hole 12 and the second through hole 32 in sequence, and then arrives in the groove 31. A nut 62 is installed in the groove 31, and the nut 62 is screwed on the circumference of the connecting column 6. The nut 62 is continuously rotated. When the nut 62 is pressed against the second gasket 33 and the limited retaining plate is pressed against the first gasket 13, the inner baffle 3 is firmly connected to the guide plate 1, thereby realizing the rapid installation of the inner baffle 3.

[0046] Reference Figure 2 and Figure 3 , a positioning hole 14 is provided on the side wall of the mounting groove 11, and the extending direction of the positioning hole 14 is the same as the extending direction of the first through hole 12. Specifically, a positioning hole 14 is provided on each side of the mounting groove 11. A positioning column 21 is integrally formed on one side of the outer guard plate 2 close to the guide plate 1. In actual production, the positioning columns 21 are usually an even number, and each two positioning columns 21 form a group, corresponding to two positioning holes 14 on the side wall of a mounting groove 11. Specifically, in this embodiment, two positioning columns 21 are provided at each of the four corners of the side of the outer guard plate 2 close to the guide plate 1, and a total of eight positioning columns 21 are provided. By aligning the four corners of the outer guard plate 2 with four of the mounting grooves 11 of the guide plate 1, the eight positioning columns 21 of the outer guard plate 2 are respectively inserted into the eight positioning holes 14 of the guide plate 1, so that the outer guard plate 2 and the guide plate 1 are accurately aligned.

[0047] Further, refer to Figure 2 and Figure 3A transverse hole 22 is formed on the side wall of each positioning column 21, and the extending direction of the transverse hole 22 is perpendicular to the positioning column 21. A side groove 15 is formed on the side wall of the first through hole 12 in a direction close to the positioning hole 14, and a contact plate 7 is slidably connected in the side groove 15. The contact plate 7 is solidly connected to the bottom of the side groove 15 by extending from the side groove 15. When the locking rod 71 is inserted into the transverse hole 22, the locking rod 71 can lock and limit the positioning column 21, thereby realizing a stable connection between the outer guard plate 2 and the guide plate 1.

[0048] Reference Figure 1 A first side hole 63 and a second side hole 64 are provided on the circumference of the connecting column 6, and a cavity 65 is provided inside the connecting column 6. At one end of the connecting column 6 close to the nut 62, two fixing frames 8 are fixedly mounted on the inner wall of the cavity 65, and the two fixing frames 8 are symmetrical about the center line of the connecting column 6. A swing rod 81 is rotatably mounted on each fixing frame 8, and the swing rod 81 extends toward the side wall of the connecting column 6. A resistance wheel 811 is rotatably mounted on one end of the swing rod 81 away from the fixing frame 8, and the resistance wheel 811 passes through the first side hole 63 and abuts against the inner ring of the nut 62. When the nut 62 is screwed onto the circumference of the connecting column 6, the nut 62 squeezes the resistance wheel 811 and retracts it into the first side hole 63, and the resistance wheel 811 causes the swing rod 81 to rotate toward the center line of the connecting column 6.

[0049] Further, refer to Figure 3 The two fixing frames 8 are rotatably mounted with gears 812, the two gears 812 mesh with each other, and one end of the swing rod 81 close to the fixing frame 8 is fixedly connected to the peripheral side of the gear 812. Through the mutual meshing of the two gears 812, the two swing rods 81 can rotate in opposite directions at the same angular velocity, so that the two swing rods 81 can be synchronously contracted inward or extended outward, avoiding the internal jamming of the connecting column 6 caused by the deviation of one side of the swing rod 81, which is conducive to improving the smoothness of the internal operation of the connecting column 6.

[0050] Reference Figure 2 and Figure 3 A moving plate 83 is slidably connected in the cavity 65 of the connecting column 6, and the moving plate 83 slides left and right in the cavity 65 along the length direction of the connecting column 6. A slanting rod 82 is hingedly connected to a side of the moving plate 83 close to the fixing frame 8, and a point of the slanting rod 82 away from the moving plate 83 is hingedly connected to the side wall of the swing rod 81. The rotation of the swing rod 81 can pull the moving plate 83 to slide in the cavity 65 through the slanting rod 82.

[0051] Reference Figure 2 and Figure 3, a push rod 831 is fixedly connected to a side of the moving plate 83 away from the inclined rod 82, and a linkage rod 85 is hingedly connected to the side wall of the end of the push rod 831 away from the moving plate 83, and a lifting platform 9 is installed on the linkage rod 85, and the lifting platform 9 is located in the second side hole 64, and the lifting platform 9 is slidably connected to the inner wall of the second side hole 64. When the push rod 831 moves to the left along the perspective of the figure, the push rod 831 pushes the lifting platform 9 to slide out along the inner wall of the second side hole 64 to the outside of the connecting column 6 through the linkage rod 85. During the movement of the push rod 831 in the connecting column 6, if the second side hole 64 is aligned with the side slot 15, the lifting platform 9 enters the side slot 15, and pushes the contact plate 7 to slide in the side slot 15 toward the direction close to the positioning hole 14, so that the locking rod 71 is inserted into the transverse hole 22, and the positioning column 21 is limited, thereby realizing the fixed connection between the outer guard plate 2 and the guide plate 1.

[0052] When installing the air deflector, the outer guard plate 2, the air deflector 1, and the inner baffle 3 are arranged in sequence, the connecting column 6 is inserted into the first through hole 12 and the second through hole 32, so that the inner baffle 3 and the air deflector 1 are aligned, and the positioning column 21 is inserted into the positioning hole 14, so that the outer guard plate 2 and the air deflector 1 are quickly aligned; the nut 62 is screwed into the side of the connecting column 6 in the groove 31, and the nut 62 pushes the swing rod 81 to retract into the first side hole 63 through the contact wheel 811, and the swing rod 81 drives the moving plate 83 and the push rod through the inclined rod 82. 831 slides, and the push rod 831 pushes the lifting platform 9 into the side groove 15 through the linkage rod 85. The positioning assembly pushes the contact plate 7 and the locking rod 71 to move in the direction close to the transverse hole 22. The locking rod 71 is inserted into the transverse hole 22 to achieve a stable connection between the outer guard plate 2 and the guide plate 1; continue to rotate the nut 62 until the nut 62 presses the second gasket 33, and the limiting retaining edge 61 presses the first gasket 13 to achieve a stable connection between the inner baffle plate 3 and the guide plate 1, thereby realizing the rapid assembly and installation of the guide cover.

[0053] When it is necessary to disassemble the air deflector, it is only necessary to loosen the nut 62 to separate the nut 62 from the connecting column 6, so that the lock of the inner baffle plate 3 and the air deflector 1 can be quickly released; after the nut 62 is taken out, the squeezing force of the nut 62 on the abutment wheel 811 disappears, and the abutment wheel 811 drives the rocker bar 81 to rotate toward the outside of the connecting column 6, and the rocker bar 81, through the chain action of the inclined rod 82, the moving plate 83, the push rod 831, and the linkage rod 85, pulls the abutment plate 7 to slide in the direction away from the positioning hole 14, and drives the locking rod 71 to be pulled out of the transverse hole 22, so as to quickly release the lock of the outer guard plate 2 and the air deflector 1; finally, the outer baffle plate, the air deflector 1 and the inner baffle plate 3 are separated one by one, so that the air deflector can be quickly disassembled.

[0054] Through the above scheme, by using a nut 62 of a certain specification to lock and separate with the connecting column 6, the two sides of the guide plate 1 can be quickly combined with the outer guard plate 2 and the inner baffle plate 3 respectively, which simplifies the assembly and disassembly operation steps of the guide cover and improves the convenience of assembly and disassembly of the guide cover. The locking on both sides of the guide plate 1 is interrelated, and during use, it can still maintain good connection stability.

[0055] In the preferred embodiment of the present application, refer to Figure 4 , multiple insertion slots 34 are evenly spaced at the upper and lower ends of the inner baffle 3, and plug plates 10 are fixed on the opposite sides of the partition 4 and the connecting hinge 5. The two plug plates 10 are respectively inserted into the two insertion slots 34 at the upper and lower ends of the inner baffle 3, and multiple connecting bolts 101 are installed on the side of the inner baffle 3 away from the guide plate 1. By inserting multiple connecting bolts 101 from the side of the plug slot 34 and screwing them on the plug plates 10, the partition 4, the connecting hinge 5 and the inner baffle 3 can be firmly connected.

[0056] In the preferred embodiment of the present application, refer to Figure 2 and Figure 3 The side of the limiting retaining edge 61 away from the outer guard plate 2 is provided with two moving holes 611, and the two moving holes 611 are symmetrically distributed on both sides of the moving hole 611 connecting column 6. A sleeve 66 is installed in the moving hole 611, and a resisting spring 67 is installed in the sleeve 66, one end of the resisting spring 67 is in contact with one end side wall in the sleeve 66, and the other end of the resisting spring 67 is in contact with one end side wall in the moving hole 611. When connecting, the limit rib 61 is inserted into the installation groove 11 along with the connecting column 6, the sleeve 66 conflicts with the first gasket 13, and the two sleeves 66 located in the same installation groove 11 are squeezed into the movable holes 611 on both sides of the limit rib 61, compressing the conflict spring 67 until the limit rib 61 presses the first gasket 13 to the bottom of the installation groove 11; when disassembling, the sleeve 66 pushes the limit rib 61 toward the outside of the installation groove 11 under the reset action of the conflict spring 67, pushing the outer guard plate 2 and the guide plate 1 to separate quickly, thereby improving the efficiency of disassembling the outer guard plate 2 and the guide plate 1.

[0057] Further, refer to Figure 2 and Figure 3 The side of the limiting retaining edge 61 close to the outer guard plate 2 is an arcuate surface 612, and the curvature of the arcuate surface 612 matches the curvature of the inner concave surface of the outer guard plate 2. When the outer guard plate 2 is installed on the side of the guide plate 1, the arcuate surface 612 fits and contacts the inner concave surface of the outer guard plate 2, limiting the displacement of the outer guard plate 2 relative to the guide plate 1, which is beneficial to improving the alignment accuracy of the outer guard plate 2 and the guide plate 1.

[0058] In the preferred embodiment of the present application, refer to Figure 2 and Figure 5The lifting platform 9 includes a first top plate 91 and a second top plate 92. A U-shaped plate 93 is slidably installed inside the first top plate 91, and the second top plate 92 is welded to the upper end of the U-shaped plate 93. A magnet is installed on the top surface of the second top plate 92, which can absorb the contact plate 7. A resistance spring 94 is placed at the lower end of the U-shaped plate 93, and one end of the resistance spring 94 away from the U-shaped plate 93 abuts against the bottom end of the inner wall of the first top plate 91. When the connecting column 6 slides in the first through hole 12, the side wall of the first through hole 12 abuts against the second top plate 92, and the second top plate 92 compresses the resistance spring 94 inside the first top plate 91; and when the second side hole 64 of the connecting column 6 is aligned with the side slot 15, the resistance spring 94 is quickly reset, so that the second top plate 92 is quickly inserted into the side slot 15 to approach and absorb the contact plate 7, so as to realize the rapid positioning of the lifting platform 9 and the contact plate 7, which is helpful to drive the locking rod 71 to limit the positioning column 21.

[0059] Further, refer to Figure 5 A guide rod 95 is vertically fixedly installed at the bottom center of the first top plate 91. The guide rod 95 passes through the center of the U-shaped plate 93. The U-shaped plate 93 slides along the direction of the guide rod 95, which can effectively limit the U-shaped frame, so that the second top plate 92 can slide linearly relative to the first top plate 91 more smoothly, avoiding internal jamming, which is beneficial to improving the loading and unloading efficiency of the air deflector.

[0060] In the preferred embodiment of the present application, refer to Figure 2 and Figure 3 The movable plate 83 is fixedly connected to a fixed plate 832 on one side close to the swing rod 81, and a movable telescopic rod 833 is rotatably installed on the fixed plate 832. The movable telescopic rod 833 is a free telescopic rod. One end of the movable telescopic rod 833 away from the fixed plate 832 is hinged to the side wall of the swing rod 81. The length of the movable telescopic rod 833 changes adaptively with the distance between the swing rod 81 and the fixed plate 832. The movable telescopic rod 833 is sleeved with a support spring 834. When the nut 62 is removed from the connecting column 6, the external force squeezing the swing rod 81 disappears, and the support spring 834 drives the swing rod 81 to rotate toward the outside of the connecting column 6. The swing rod 81 drives the inclined rod 82 to move, and the inclined rod 82 quickly pulls the movable plate 83 to slide to the right, so that the push rod 831, the linkage rod 85 and the top plate assembly on the left are reset, and the lock rod 71 is quickly pulled out of the transverse hole 22, thereby realizing the rapid unlocking of the positioning column 21, which is conducive to improving the disassembly efficiency of the outer guard plate 2 and the guide plate 1.

[0061] Further, refer to Figure 2 and Figure 3The end of the movable plate 83 away from the push rod 831 is fixedly connected with a distance adjusting member 835, and the fixed plate 832 is fixedly installed on the end of the distance adjusting member 835 away from the movable plate 83. The distance adjusting member 835 is a telescopic rod with a self-locking function, which can be a micro cylinder or a combination of two sleeves 66 connected by threads. The distance adjusting member 835 can change the angle between the movable telescopic rod 833 and the swing rod 81 by adjusting the distance between the fixed plate 832 and the movable plate 83, and then adjust the maximum angle that the swing rod 81 can deviate from the center line of the connecting column 6, and then change the sliding stroke of the movable plate 83 through the inclined rod 82, and finally further change the stroke of the push rod 831 and the linkage rod 85, so as to adjust the sliding stroke range of the lifting platform 9 relative to the second side hole 64, adapt to the connecting columns 6 of different specifications, and help meet the installation requirements of different specifications.

[0062] In a second aspect, the present application also provides a method for forming a rail vehicle air deflector, which is applicable to the rail vehicle air deflector component structure, and adopts the following technical solution, including the following steps:

[0063] S1.

[0064] S2. Place the inner baffle 3 on the concave side of the guide plate 1 so that the first through hole 12 is aligned with the second through hole 32; insert one end of the connecting column 6 from the mounting groove 11, and the connecting column 6 passes through the first through hole 12 and the second through hole 32 and extends into the groove 31, so as to realize the rapid positioning of the inner baffle 3 and the guide plate 1;

[0065] S3, the outer guard plate 2 is placed on the convex side of the guide plate 1, the outer guard plate 2 squeezes the limiting retaining edge 61 into the installation groove 11, and the positioning column 21 is inserted into the positioning hole 14 to achieve rapid positioning of the outer guard plate 2 and the guide plate 1;

[0066] S4, screw the nut 62 onto the side of the connecting column 6, the inner ring of the nut 62 contacts the driving contact wheel 811 to retract into the first side hole 63, the swing rod 81 approaches the center line of the connecting column 6, the swing rod 81 moves the moving plate 83 in the direction close to the push rod 831 through the inclined rod 82, the push rod 831 drives the linkage rod 85 to push the lifting platform 9 during the movement, the lifting platform 9 enters the side groove 15, the lifting platform 9 pushes the contact plate 7, the locking rod 71 is inserted into the transverse hole 22, and the outer guard plate 2 and the guide plate 1 are installed and fixed;

[0067] S5. Continue to rotate the nut 62 until the limiting rib 61 abuts against the first gasket 13 at the bottom of the installation groove 11, and the nut 62 abuts against the second gasket 33 at the bottom of the groove 31, thereby achieving installation and fixation of the inner baffle 3 and the guide plate 1.

[0068] Through the above method, when assembling, the outer guard plate 2, the guide plate 1 and the inner baffle plate 3 are quickly aligned through the connecting column 6 and the nut 62, and then the nut 62 is rotated. Through the coordinated linkage of multiple components in the connecting column 6, the outer guard plate 2 and the guide plate 1 are automatically locked, and the nut 62 is tightened, and then the inner baffle plate 3 and the guide plate 1 are locked, thereby realizing the rapid assembly of the air deflector, effectively ensuring the stability of the position between the plates, and avoiding looseness; when disassembly is required, only the nut 62 and the connecting column 6 need to be separated to complete the separation of the outer guard plate 2, the guide plate 1 and the inner baffle plate 3, thereby improving the convenience of loading and unloading the air deflector.
