Description
Technical Field
[0001] This invention relates to the field of auxiliary equipment technology for display devices, and in particular to a shock-absorbing and energy-absorbing device for vehicle-mounted displays. Background Technology
[0002] With the rapid development of rail transit technology, subways, high-speed trains, and bullet trains have become the main modes of transportation for people. To improve the passenger experience and information access efficiency, onboard displays are usually installed inside the carriages to display arrival information, public service announcements, and multimedia entertainment content. These displays are typically mounted on the carriage walls or ceiling structure using mounting brackets.
[0003] However, in practical applications, existing train display mounting devices still have the following shortcomings: During high-speed train operation, factors such as track irregularities, track changes, and acceleration / deceleration cause complex mechanical vibrations in the train body. These vibrations are not unidirectional but encompass multidimensional vibrations including vertical swaying, lateral swaying, and forward / backward impact. Existing monitor mounting brackets mostly use rigid connections or simply add rubber pads, often providing only weak buffering in a single direction (usually vertical), making it difficult to cope with complex multidirectional vibrations. Prolonged rigid vibrations not only cause monitor screen flickering, affecting the passenger viewing experience, but also easily lead to loosening of delicate electronic components inside the monitor, solder joint detachment, and severely shorten the equipment's lifespan.
[0004] Monitors generate significant heat during prolonged high-brightness operation. If this heat isn't dissipated promptly, it can lead to component aging or even system failure. Current cooling solutions primarily fall into two categories: one relies on passive, natural heat dissipation from the casing, which is inefficient and inadequate for handling the high temperatures accumulated in the enclosed carriage; the other involves installing electric cooling fans, which improves cooling but requires additional power lines, increasing the electrical load and wiring complexity within the carriage. Simultaneously, the continuous vibrations generated during train operation contain a substantial amount of mechanical energy. Current technology often treats this vibration as a "harmful factor" and simply suppresses it, failing to convert it into beneficial energy to aid in equipment cooling, resulting in energy waste.
[0005] The monitor requires power and signal cables to operate. Existing mounting brackets often lack dedicated cable management structures, with wires typically exposed or simply bundled on the outside of the bracket. Under the long-term vibration of a train, loose cables can easily rub against the metal bracket, causing insulation wear and potentially leading to short circuits. Furthermore, messy cables detract from the overall neatness and aesthetics of the carriage interior, making subsequent inspection and maintenance inconvenient. Summary of the Invention
[0006] To achieve the above objectives, the present invention employs the following technical solution: a vehicle-mounted display screen shock-absorbing device, comprising: a mounting bracket and a display mounting bracket, a vertical sliding fit structure, a horizontal sliding fit structure, and a wiring harness management mechanism; a vertical buffer plate is provided within the mounting bracket, and the vertical buffer plate is installed within the mounting bracket via the vertical sliding fit structure; a horizontal buffer strip is provided on the vertical buffer plate, and the horizontal buffer strip is installed on the vertical buffer plate via the horizontal sliding fit structure; the display mounting bracket is fixedly connected to the front side of the horizontal buffer strip; it further includes a first buffer, disposed on the sliding fit path between the mounting bracket and the vertical buffer plate, for limiting vertical displacement; a second buffer, disposed on the fit path between the vertical buffer plate and the horizontal buffer strip, for limiting horizontal displacement; and a heat dissipation assembly, connected between the vertical buffer plate and the horizontal buffer strip, for converting the horizontal reciprocating motion of the horizontal buffer strip into rotational motion to generate heat dissipation airflow.
[0007] The technical effect of adopting the above-mentioned further solution is that by setting up vertical buffer plates and horizontal buffer bars, in conjunction with the first buffer and the second buffer, the multi-directional vibration during train operation can be effectively mitigated, thus protecting the display equipment.
[0008] In a preferred embodiment, the vertical sliding fit structure includes vertical grooves formed on both sides of the inner wall of the mounting bracket, and sliders fixed on both sides of the vertical buffer plate; the sliders are slidably engaged inside the vertical grooves; the first buffer is disposed on the upper and lower sides of the sliders.
[0009] The technical effect of adopting the above-mentioned further solution is that: by cooperating with the vertical groove on the inner wall of the mounting bracket and the slider, the movement freedom of the vertical buffer plate is restricted, ensuring that it can only move smoothly in the vertical direction, and preventing the mechanism from jamming due to uneven force; the first buffer is distributed on the upper and lower sides, which can flexibly absorb the vertical impact peak when the train bumps, and greatly improve the stability of the display screen in the vertical dimension.
[0010] In a preferred embodiment, the transverse sliding fit structure includes a transverse groove formed on the surface of the vertical buffer plate; the transverse buffer strip slides within the transverse groove; and the second buffer is disposed at both ends of the transverse buffer strip on the sliding path of the transverse groove.
[0011] The technical effects of adopting the above-mentioned further solution are as follows: the design of the transverse groove allows the transverse buffer strip to slide independently inside the vertical buffer plate, realizing the decoupling of transverse damping and vertical damping, so that they do not interfere with each other; together with the second buffers on both sides, it can effectively dampen and dissipate the shear force generated by the left and right swaying of the train, further improving the device's adaptability to complex road conditions.
[0012] In a preferred embodiment, a buffer is fixedly installed on one side of the display mounting bracket. The buffer is installed between the transverse buffer strip and the display mounting bracket to provide elastic damping in the front-to-back direction.
[0013] The technical effect of adopting the above-mentioned further solution is that the addition of the buffer component improves the three-dimensional shock absorption and protection system, and provides flexible support for the front and rear inertial forces generated when the train brakes suddenly, accelerates or shakes violently, avoiding hard collisions between the display mounting bracket and the rigid structure on the back, and effectively protecting the precision electronic components inside the display from vibration damage.
[0014] In a preferred embodiment, the heat dissipation assembly includes a fixing strip, a rack, a large gear, a small gear, and a cooling fan; the fixing strip is fixedly installed on the outer surface of the vertical buffer plate; the large gear and the small gear are rotatably connected to one side of the fixing strip; the rack is fixedly connected to the outer surface of the horizontal buffer strip, and the rack meshes with the large gear.
[0015] The technical advantages of adopting the above-mentioned further solution are: by utilizing the meshing connection between the rack and the large gear, the disordered reciprocating linear motion of the transverse buffer bar is accurately and continuously converted into the rotational motion of the gear set, resulting in a compact structure and reliable transmission; the fixed bar provides a stable support base for the gear set, ensuring mechanical stability during the energy transfer process.
[0016] In a preferred embodiment, the diameter of the large gear is larger than the diameter of the small gear, the large gear drives the small gear to rotate, and the cooling fan is installed at the end of the rotating shaft of the small gear.
[0017] The technical advantage of adopting the above-mentioned further solution is that by utilizing the design that the diameter of the large gear is larger than that of the small gear, a physical speed-increasing mechanism is formed, and the rotational speed is amplified by the transmission ratio. This means that even if the train only experiences slight, low-frequency shaking, it can drive the cooling fan to rotate at high speed, ensuring that sufficient cooling airflow is generated at various operating speeds, thereby improving cooling efficiency.
[0018] In a preferred embodiment, the display mounting bracket is a frame structure with multiple elongated holes on its surface. The positions of the elongated holes correspond to the airflow direction of the heat dissipation component, allowing for airflow.
[0019] The technical effect of adopting the above-mentioned further solution is that the position of the elongated hole on the surface of the monitor mounting bracket is precisely aligned with the fan. This not only reduces the overall weight of the bracket, but more importantly, it forms a low-resistance straight flow channel, allowing the airflow generated by the cooling fan to directly blow on the heat source area of the monitor back panel, greatly improving the heat exchange efficiency and preventing heat accumulation.
[0020] In a preferred embodiment, the wire harness management mechanism includes a wire harness groove and limiting components disposed on both sides of the wire harness groove; the wire harness groove is arranged in a horizontal direction and is used to accommodate cables.
[0021] The technical effect of adopting the above-mentioned further solution is that the setting of the wire harness groove makes full use of the idle space at the top of the mounting bracket, and centrally hides the originally messy and exposed connecting cables, which not only eliminates the safety hazards caused by the cables hanging, but also maintains the cleanliness and aesthetics of the interior environment of the carriage.
[0022] In a preferred embodiment, the limiting component includes a U-shaped block, a protruding strip, a spring, and a short rod; the U-shaped block is located at the top of the wire harness groove, the short rod is fixedly installed on one side of the U-shaped block, and the spring is sleeved on the short rod and abuts against the top of the protruding strip, for applying a spring force to the U-shaped block to compress the cable.
[0023] The technical advantage of adopting the above-mentioned further solution is that the elastic self-locking structure of the spring-driven U-shaped block can always apply a constant clamping force to the inserted cable. No matter how the train vibrates, the U-shaped block can remain firmly attached to the cable surface, preventing the cable from loosening and rubbing within the cable harness groove.
[0024] In a preferred embodiment, the wire harness organizing mechanism further includes an L-shaped block, a connecting strip, a linkage rod, and a limiting circle block; one end of the linkage rod is connected to the connecting strip, and the other end of the linkage rod passes through the L-shaped block and is connected to the limiting circle block; the limiting circle block is fixed to the end of the short rod away from the U-shaped block; by pulling the connecting strip, the linkage rod and the short rod are moved, thereby compressing the spring and releasing the U-shaped block.
[0025] The technical advantage of adopting the above-mentioned further solution is that, through the lever linkage design of the connecting bar and the linkage rod, the operator only needs to pull the connecting bar outward with one hand to move the component through the limiting block and compress the spring, thereby quickly opening the storage port. The insertion and removal of cables do not require any auxiliary tools, improving work efficiency.
[0026] Compared with the prior art, the advantages and positive effects of the present invention are as follows: 1. In this embodiment of the invention, the mounting bracket is fixed to the carriage wall, and the display is mounted on the display mounting bracket. To address the complex vibrations generated during train operation, the device employs a three-dimensional buffering mechanism: when the train body experiences vertical bumps, the vertical buffer plate uses sliders on both sides to guide sliding within the vertical groove, working in conjunction with the first buffers positioned above and below to elastically limit displacement, thereby eliminating longitudinal impact; when lateral swaying occurs, the lateral buffer strip undergoes relative displacement under the guidance of the horizontal grooves of the vertical buffer plate, and absorbs lateral kinetic energy through the second buffer; furthermore, to address the forward and backward inertial forces generated by sudden braking or acceleration, the device provides flexible support through a buffer component on the back, preventing a hard collision between the display back panel and the rigid bracket. This multi-level linkage structural design ensures the stability of the display screen in all dimensions—vertical, horizontal, and front-back. It should be noted that the buffer component can be any elastic structure, and no limitations are imposed here.
[0027] 2. In this embodiment of the invention, when the transverse buffer bar moves back and forth within the groove as the train body sways, it drives the fixed rack to move synchronously. The rack meshes and drives the large gear to rotate, which in turn drives the meshing small gear to rotate. Based on the principle of gear transmission ratio, since the circumference of the large gear is much larger than that of the small gear, a significant speed-up effect is achieved, enabling the small gear to drive the cooling fan to rotate at high speed. Regardless of whether the train sways to the left or right, the continuous rotation of the fan blades generates airflow, which passes through the elongated holes on the surface of the monitor mounting bracket, providing forced air cooling to the back of the monitor.
[0028] 3. In this embodiment of the invention, when it is necessary to organize the display's connecting cables, simply pull the connecting strip outwards. This movement is transmitted to the limiting component via the linkage rod, causing the limiting block, short rod, and U-shaped block to move synchronously. This compresses the spring and opens the storage space of the wire harness slot. After folding the redundant wires into the wire harness slot, the connecting strip is released. Under the elastic restoring force of the spring, the U-shaped block automatically resets and presses tightly against the wire surface, firmly confining the wire harness within the slot. This maintains the cleanliness and aesthetics of the carriage environment and prevents loose cables from being damaged by train vibrations. Attached Figure Description

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.
[0032] Please see Figures 1 to 6 This embodiment provides a technical solution: a vehicle-mounted display screen shock-absorbing device, comprising: a mounting frame 101 and a display mounting frame 109, a vertical sliding fit structure, a horizontal sliding fit structure, and a wire harness management mechanism; a vertical buffer plate 105 is provided inside the mounting frame 101, and the vertical buffer plate 105 is installed inside the mounting frame 101 through the vertical sliding fit structure; a horizontal buffer strip 108 is provided on the vertical buffer plate 105, and the horizontal buffer strip 108 is installed on the vertical buffer plate 105 through the horizontal sliding fit structure; the display mounting frame 109 is fixedly connected to the front side of the horizontal buffer strip 108; It also includes a first buffer 103, which is disposed on the sliding engagement path between the mounting bracket 101 and the vertical buffer plate 105, for limiting vertical displacement; a second buffer 106, which is disposed on the engagement path between the vertical buffer plate 105 and the horizontal buffer bar 108, for limiting horizontal displacement; and a heat dissipation assembly, which is connected between the vertical buffer plate 105 and the horizontal buffer bar 108, for converting the horizontal reciprocating motion of the horizontal buffer bar 108 into rotational motion to generate heat dissipation airflow.
[0033] In use, by setting up vertical buffer plates 105 and horizontal buffer bars 108, together with the first buffer 103 and the second buffer 106, the multi-directional vibrations during train operation are effectively mitigated, protecting the display equipment.
[0034] like Figures 1 to 6 As shown, in one embodiment, the vertical sliding engagement structure includes vertical grooves 102 formed on both sides of the inner wall of the mounting bracket 101, and sliders 104 fixed on both sides of the vertical buffer plate 105; the sliders 104 are slidably engaged inside the vertical grooves 102; the first buffers 103 are disposed on the upper and lower sides of the sliders 104, and through the engagement of the vertical grooves 102 on the inner wall of the mounting bracket 101 with the sliders 104, the movement freedom of the vertical buffer plate 105 is restricted, ensuring that it can only move smoothly in the vertical direction, and preventing the mechanism from jamming due to uneven force; the first buffers 103 are distributed on the upper and lower sides, and can flexibly absorb the vertical impact peak during train bumps, greatly improving the stability of the display screen in the vertical dimension.
[0035] like Figures 1 to 6 As shown, in one embodiment, the lateral sliding fit structure includes a transverse groove 107 formed on the surface of the vertical buffer plate 105; a transverse buffer strip 108 slides within the transverse groove 107; and second buffers 106 are disposed at both ends of the transverse buffer strip 108 on the sliding path of the transverse groove 107. The design of the transverse groove 107 allows the transverse buffer strip 108 to slide independently within the vertical buffer plate 105, achieving decoupling of lateral damping and vertical damping, so that they do not interfere with each other. With the cooperation of the second buffers 106 on both sides, the shear force generated by the left and right swaying of the train can be effectively damped and energy dissipated, further improving the device's adaptability to complex road conditions.
[0036] like Figures 1 to 6 As shown, in one embodiment, a buffer 125 is fixedly installed on one side of the display mounting bracket 109. The buffer 125 is installed between the transverse buffer strip 108 and the display mounting bracket 109 to provide elastic damping in the front-back direction. The addition of the buffer 125 improves the three-dimensional shock absorption and protection system, and provides flexible support for the front-back inertial forces generated when the train brakes suddenly, accelerates or shakes violently. This avoids hard collisions between the display mounting bracket 109 and the rigid structure at the back, and effectively protects the precision electronic components inside the display from vibration damage.
[0037] like Figures 1 to 6As shown, in one embodiment, the heat dissipation assembly includes a fixing strip 115, a rack 111, a large gear 112, a small gear 113, and a cooling fan 114. The fixing strip 115 is fixedly installed on the outer surface of the vertical buffer plate 105. The large gear 112 and the small gear 113 are rotatably connected to one side of the fixing strip 115. The rack 111 is fixedly connected to the outer surface of the horizontal buffer strip 108, and the rack 111 meshes with the large gear 112. By utilizing the meshing connection between the rack 111 and the large gear 112, the disordered reciprocating linear motion of the horizontal buffer strip 108 is accurately and continuously converted into the rotational motion of the gear set. The structure is compact and the transmission is reliable. The fixing strip 115 provides a stable support base for the gear set, ensuring the mechanical stability during the energy transfer process.
[0038] like Figures 1 to 6 As shown, in one embodiment, the diameter of the large gear 112 is larger than the diameter of the small gear 113. The large gear 112 drives the small gear 113 to mesh and rotate. The cooling fan 114 is installed at the end of the rotating shaft of the small gear 113. By utilizing the design that the diameter of the large gear 112 is larger than that of the small gear 113, a physical speed-increasing mechanism is formed, which amplifies the rotational speed by utilizing the transmission ratio. This means that even if the train only experiences slight, low-frequency shaking, it can drive the cooling fan 114 to rotate at high speed, ensuring that sufficient cooling airflow can be generated at various travel speeds, thereby improving cooling efficiency.
[0039] like Figures 1 to 6 As shown, in one embodiment, the monitor mounting bracket 109 is a frame structure with multiple elongated holes 110 on its surface. The positions of the elongated holes 110 correspond to the airflow direction of the heat dissipation components, allowing airflow. The positions of the elongated holes 110 on the surface of the monitor mounting bracket 109 are precisely aligned with the fan, which not only reduces the overall weight of the bracket but, more importantly, forms a low-resistance straight-through channel, allowing the airflow generated by the cooling fan 114 to directly blow on the heat source area of the monitor back panel, greatly improving heat exchange efficiency and preventing heat accumulation.
[0040] like Figures 1 to 6 As shown, in one embodiment, the wire harness management mechanism includes a wire harness groove 116 and limiting components disposed on both sides of the wire harness groove 116; the wire harness groove 116 is arranged in a horizontal direction to accommodate cables. The arrangement of the wire harness groove 116 makes full use of the idle space on the top of the mounting bracket 101, and centrally and conceals the originally messy and exposed connecting cables, which not only eliminates the safety hazards caused by the cables falling, but also maintains the cleanliness and aesthetics of the interior environment of the carriage.
[0041] like Figures 1 to 6As shown, in one embodiment, the limiting component includes a U-shaped block 119, a protrusion 117, a spring 120, and a short rod 121. The U-shaped block 119 is located at the top of the wire harness groove 116, and the short rod 121 is fixedly installed on one side of the U-shaped block 119. The spring 120 is sleeved on the short rod 121 and abuts against the top of the protrusion 117, used to apply a spring force to the U-shaped block 119 to press the cable. The elastic self-locking structure of the U-shaped block 119 driven by the spring 120 can always apply a constant pressing force to the inserted cable. No matter how the train vibrates, the U-shaped block 119 can keep close to the cable surface, preventing the cable from loosening and rubbing within the wire harness groove 116.
[0042] like Figures 1 to 6 As shown, in one embodiment, the cable management mechanism further includes an L-shaped block 122, a connecting strip 123, a linkage rod 124, and a limiting block 118. One end of the linkage rod 124 is connected to the connecting strip 123, and the other end of the linkage rod 124 passes through the L-shaped block 122 and is connected to the limiting block 118. The limiting block 118 is fixed to the end of the short rod 121 away from the U-shaped block 119. By pulling the connecting strip 123, the linkage rod 124 and the short rod 121 are moved, thereby compressing the spring 120 and releasing the U-shaped block 119. Through the lever linkage design of the connecting strip 123 and the linkage rod 124, the operator only needs to pull the connecting strip 123 outward with one hand to move the components through the limiting block 118 and compress the spring 120, thereby quickly opening the storage port. The insertion and removal of cables do not require any auxiliary tools, improving work efficiency.
[0043] Working principle: The mounting bracket 101 is fixed to the carriage wall, and the display is mounted on the display mounting bracket 109. To address the complex vibrations generated during train operation, the device employs a three-dimensional buffering mechanism: when the train body experiences vertical bumps, the vertical buffer plate 105 slides within the vertical groove 102 using sliders 104 on both sides, working in conjunction with the first buffer 103 positioned above and below to elastically limit displacement, thereby eliminating longitudinal impact; when lateral swaying occurs, the lateral buffer strip 108 undergoes relative displacement under the guidance of the horizontal groove 107 of the vertical buffer plate 105, and absorbs lateral kinetic energy through the second buffer 106; furthermore, to address the forward and backward inertial forces generated by sudden braking or acceleration, the device provides flexible support through the buffer 125 positioned at the back, preventing hard collisions between the display back panel and the rigid bracket. This multi-level linkage structural design ensures the stability of the display screen in all dimensions—vertical, horizontal, and forward / backward. It should be noted that the buffer 125 can be any elastic structure, without any restrictions.
[0044] As the transverse buffer bar 108 moves back and forth within the groove with the train's swaying, it drives the fixed rack 111 to move synchronously. The rack 111 meshes and drives the large gear 112 to rotate, which in turn drives the connected small gear 113 to rotate. Based on the principle of gear ratio, since the circumference of the large gear 112 is much larger than that of the small gear 113, a significant speed-up effect is achieved, enabling the small gear to drive the cooling fan 114 to rotate at high speed. Regardless of whether the train sways to the left or right, the continuous rotation of the fan blades generates airflow, which passes through the elongated holes 110 on the surface of the monitor mounting bracket, providing forced air cooling to the back of the monitor.
[0045] When it's necessary to organize the monitor's wiring, simply pull the connecting strip 123 outwards. This is transmitted through the linkage rod 124 to the limiting component, causing the limiting block 118, short rod 121, and U-shaped block 119 to move synchronously. This compresses the spring 120 and opens the storage space of the wire harness slot 116. After folding the excess wires into the slot, release the connecting strip. Under the elastic restoring force of the spring 120, the U-shaped block 119 automatically resets and presses firmly against the wire surface, securely containing the wire harness within the slot. This maintains the cleanliness and aesthetics of the carriage environment and prevents loose cables from being damaged by train vibrations.
