[0035] In order to enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0036] Please refer to Figures 1 to 5 , Figure 1 This is a schematic front view of a specific embodiment of the single-slide pantograph head assembly structure provided by the present invention; Figure 2This is a schematic top view of a specific embodiment of the single-slide pantograph head assembly structure provided by the present invention; Figure 3 This is a schematic diagram of the internal structure of a specific embodiment of the single-slide pantograph head assembly structure provided by the present invention; Figure 4 This is a structural diagram of the bracket assembly in a specific embodiment of the single-slide pantograph head assembly structure provided by the present invention; Figure 5 This is a structural schematic diagram of the slide assembly in a specific embodiment of the single-slide pantograph head assembly structure provided by the present invention.

[0037] A specific embodiment of the present invention provides a single-slide pantograph bow head assembly structure, including a spring assembly 8, a first bracket assembly 3, a second bracket assembly 6 and a slide assembly 4. The first bracket assembly 3 and the second bracket assembly 6 are arranged on both sides of the spring assembly 8, and the lower end of the first bracket assembly 3 and the lower end of the second bracket assembly 6 are respectively connected to the two sides of the rear end of the spring assembly 8. At the same time, the upper end of the first bracket assembly 3 and the upper end of the second bracket assembly 6 are connected to and support the slide assembly 4. Furthermore, the torsion spring assembly in the spring assembly 8 is arranged horizontally, and the upper and lower sides of the front end of the spring assembly 8 are installed with an upper cover plate 2 and a lower cover plate 5, and the upper side of the rear end of the spring assembly 8 is installed with a rear cover plate 1. The upper cover plate 2, the lower cover plate 5 and the rear cover plate 1 wrap the spring assembly 8.

[0038] The torsion spring assembly is arranged horizontally, the height of the spring assembly 8 is lowered, and the spring assembly 8 is wrapped by a cover plate, providing a simple aerodynamic shape, reducing the windward area of the component, ensuring the flow quality of the bow net, reducing air resistance and noise, and having good aerodynamic performance and drag and noise reduction effects.

[0039] Specifically, spring assembly 8 comprises a base 81, multiple torsion spring assemblies, and two rotating shafts 87. Both the torsion spring assemblies and rotating shafts 87 extend horizontally in the longitudinal direction, with the multiple torsion spring assemblies sequentially arranged in the transverse direction and mounted at the front end of base 81. Two rotating shafts 87 are mounted on either side of the rear end of base 81. The rear end of each torsion spring assembly is connected to the front end of the rotating shaft 87 via a transmission mechanism. The rear ends of the two rotating shafts 87 are respectively connected to the first bracket assembly 3 and the second bracket assembly 6. Base 81 is an A-shaped bracket that opens rearward and comprises a horizontally arranged front and rear crossbeams, as well as two longitudinal beams disposed on either side of the front and rear crossbeams. The two longitudinal beams extend rearward and protrude from the rear crossbeam. A torsion shaft 7 is disposed between the two longitudinal beams and is located between the rear crossbeams. Multiple torsion spring assemblies are disposed between the front and rear crossbeams, and the two rotating shafts 87 are disposed on the two longitudinal beams.

[0040] Both the first bracket assembly 3 and the second bracket assembly 6 include a fixed plate 31, a connecting seat 33, and a swing arm 34. The fixed plate 31 is connected to the slide assembly 4. The upper end of the connecting seat 33 is hinged to the fixed plate 31, while the lower end of the connecting seat 33 is hinged to the outer end of the swing arm 34. The inner end of the swing arm 34 is connected to the rotating shaft 87 of the spring assembly 8. Each hinge axis is arranged horizontally along the longitudinal direction and parallel to the extension direction of the rotating shaft 87, enabling the vertical displacement of the slide assembly 4. Furthermore, air deflectors 32 are installed on both the front and rear sides of the connecting seat 33 to reduce wind resistance in this area.

[0041] The skateboard assembly 4 includes a carbon skateboard 43, a profile bow angle 42 connecting the lateral ends of the carbon skateboard 43, and an insulating bow angle 41 connecting the profile bow angle 42. The profile bow angle 42 can be an aluminum bow angle. The upper outer contour of the skateboard assembly 4 meets the vehicle limit requirements.

[0042] Please refer to Figures 6 to 10 , Figure 6 This is a top view schematic diagram of the spring assembly in a specific embodiment of the single-slide pantograph head assembly structure provided by the present invention; Figure 7 for Figure 6 AA sectional view; Figure 8 for Figure 6 BB cross-sectional view; Figure 9 This is a schematic front view of a spring assembly in a specific embodiment of the single-slide pantograph head assembly structure provided by the present invention; Figure 10 This is a structural schematic diagram of the torsion spring assembly in a specific embodiment of the single-slide pantograph head assembly structure provided by the present invention.

[0043] On the basis of the single-slide pantograph bow head assembly structure provided in the above-mentioned specific embodiments, a total of four torsion spring assemblies are set, namely the first left-handed torsion spring assembly 82, the first right-handed torsion spring assembly 83, the second left-handed torsion spring assembly 84 and the second right-handed torsion spring assembly 85 arranged in sequence along the horizontal direction, with left-hand and right-hand rotation arranged alternately, and the transmission mechanism is specifically a gear mechanism.

[0044] The front end of the rotating shaft 87 is connected to the rear cross beam of the base 81 through the front bearing and is covered and protected by the front end cover 88. The middle part of the rotating shaft 87 is connected to the longitudinal beam of the base 81 through the rear bearing and is covered and protected by the rear end cover 811. A sector gear 86 is installed at the front end of the rotating shaft 87, and the sector gear 86 is located on the rear side of the rear cross beam. A cylindrical half gear 89 is installed at the rear ends of the first left-handed torsion spring assembly 82 and the second right-handed torsion spring assembly 85, and the cylindrical half gear 89 is located on the rear side of the rear cross beam. A cylindrical gear 810 is installed at the rear ends of the first right-handed torsion spring assembly 83 and the second left-handed torsion spring assembly 84, and the cylindrical gear 810 is located on the rear side of the rear cross beam, so that adjacent gears are meshed in sequence, the sector gear 86 on the left meshes with the cylindrical half gear 89 on the left, the cylindrical half gear 89 on the left meshes with the cylindrical gear 810 on the left, the two cylindrical gears 810 located in the middle mesh, the cylindrical gear 810 on the right meshes with the cylindrical half gear 89 on the right, and the cylindrical half gear 89 on the right meshes with the sector gear 86 on the right. During operation, the slide assembly 4 moves up and down, causing the bracket assembly to expand or fold. This in turn causes the swing arm 34 to rotate the shaft 87. The two shafts 87 rotate in opposite directions. This rotation of the shaft 87 sequentially drives the cylindrical half gears 89 and the cylindrical gear 810 to rotate. Similarly, the two cylindrical half gears 89 rotate in opposite directions, and the two cylindrical gears 810 rotate in opposite directions. Because the left-handed and right-handed torsion springs are alternately arranged, the rotation directions of the gears also alternate, resulting in the same torque being generated by each torsion spring assembly. This ensures the synchronous movement of the four torsion spring assemblies, ensuring the synchronization of the support movements at both ends of the slide assembly 4. The up and down movement of the carbon slide 43 remains linear, resulting in excellent pantograph-net matching performance.

[0045] Preferably, the front crossbeam of the base 81 is provided with a waist-shaped hole, through which an adjustment screw 812 is inserted to connect to the torsion spring assembly. The waist-shaped hole allows the installation angle of the torsion spring assembly to be adjusted, thereby adjusting the initial spring force of the torsion spring. A positioning block 813 is provided on the rear crossbeam of the base 81 to limit the rotation angle of the stepped shaft 851. This limits the rotation angle of the stepped shaft 851, thereby limiting the final downward travel of the slide assembly 4. The front cover 88 and rear cover 811 also constrain the displacement of the rotating shaft 87 along its axis.

[0046] Based on the single-slide pantograph head assembly structure provided in each of the aforementioned embodiments, the structures of the four torsion spring assemblies are similar, differing only in the helical direction of the torsion springs. The torsion spring assembly comprises a stepped shaft 851 extending horizontally in the longitudinal direction. The front end of the stepped shaft 851 is hingedly connected to the front crossbeam of the base 81 via a second bearing 857. The rear end of the stepped shaft 851 is hingedly connected to the rear crossbeam of the base 81 via a first bearing 852. The rear end of the stepped shaft 851 passes through the rear crossbeam and protrudes from the rear side of the rear crossbeam, thereby connecting to the corresponding gear. A fixed block 856 is mounted on the front end of the stepped shaft 851, which is affixed to the rear side of the front crossbeam and fixedly connected. A torsion spring 855 is mounted on the stepped shaft 851, with the front end of the torsion spring 855 fixedly connected to the fixed block 856 and the rear end of the torsion spring 855 fixedly connected to the stepped shaft 851. Specifically, grooves are provided at corresponding positions on the fixed block 856 and the stepped shaft 851, with the ends of the torsion spring 855 inserted into the two grooves.

[0047] Furthermore, a rearward-extending stop rod 854 is mounted on the fixed block 856. Two stop screws 853 are provided on the stepped shaft 851. The rear end of the stop rod 854 is positioned between the two stop screws 853 and contacts the stop screw 853 rotating in the same direction as the torsion spring. When the stepped shaft 851 rotates, the stop rod 854 contacts the other stop screw 853 and deforms. Specifically, in a normal state, the stop rod 854 is positioned between the two stop screws 853 and contacts the stop screw 853 rotating in the same direction as the torsion spring 855. When the stepped shaft 851 rotates, it drives the torsion spring 855 thereon to rotate, generating a spring force. Simultaneously, the stop rod 854 contacts the other stop screw 853 and deforms, thereby achieving a secondary stiffness change.

[0048] In the above specific embodiments, the shaft hole can be connected by a single key or a spline, the components can be connected by bolts, or multiple connection methods can be used, all of which are within the scope of protection of the present invention.

[0049] In addition to the above-mentioned single-slide pantograph bow head assembly structure, a specific embodiment of the present invention also provides a rail vehicle including the above-mentioned single-slide pantograph bow head assembly structure. For the structures of other parts of the rail vehicle, please refer to the prior art and will not be described in detail herein.

Specific examples are used herein to illustrate the principles and implementation methods of the present invention. The description of the above embodiments is only intended to help understand the method and core concept of the present invention. It should be pointed out that for ordinary technicians in this technical field, without departing from the principles of the present invention, several improvements and modifications can be made to the present invention, and these improvements and modifications also fall within the scope of protection of the claims of the present invention.
