[0031] In order to make the technical solutions and advantages of the embodiments of the present application more clearly understood, the exemplary embodiments of the present application are further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present application, and are not an exhaustive list of all embodiments. It should be noted that the embodiments and features in the embodiments of the present application can be combined with each other unless they conflict.
[0032] The present invention provides a display screen that is impact-resistant and drop-resistant, and its structure is as follows: Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, it includes a protective frame 1, a wavy groove 101, an elastic filling body 102, a display unit 2, a buffer column 201, a heat conducting sheet 3, a heat dissipation fin 4, a limiting groove 202, a limiting bar 203, an elastic support block 501, a sliding rod 502, an elastic member 503, a corner guard 601, an energy absorbing layer 602, a driving unit 701, a first transmission gear 702, a transmission shaft 703, a second transmission gear 704, a soft cam 705, a ventilation pipe 801, a fan 802, an adjusting screw 901, an adjusting plate 902, and an elastic pad 903. The specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.
[0033] The protective frame 1 is the basic structure of the entire display screen, and its outer surface is provided with a plurality of groups of wave-shaped grooves 101. The shape and distribution of the wave-shaped grooves 101 are as follows: Figure 3As shown, an elastic filler 102 is embedded within the wavy groove 101, secured thereto by bonding or snapping. The design of the wavy groove 101 increases the surface area of the protective frame 1 while absorbing external impact forces through the elastic properties of the elastic filler 102. A heat dissipation channel is defined within the protective frame 1, arranged circumferentially along the protective frame 1 and adjacent to the sides of the display unit 2. The channel's path design ensures smooth airflow and covers the primary heat-generating areas of the display unit 2.
[0034] The display unit 2 is fixedly mounted on the protective frame 1, and a plurality of buffer columns 201 are arranged between the two. The specific connection method of the buffer columns 201 is as follows: Figure 3 As shown, one end of the buffer column 201 is fixedly connected to the back of the display unit 2 via screws, and the other end is connected to the inner wall of the protective frame 1 via a snap-fit structure. The snap-fit structure is formed by the protrusion at the end of the buffer column 201 mating with a groove in the inner wall of the protective frame 1. This connection method ensures the stability of the buffer column 201 while allowing it to undergo a certain degree of elastic deformation when subjected to force. The buffer column 201 is made of highly elastic rubber, which can effectively absorb impact forces from different directions and distribute them to the protective frame 1.
[0035] The edge of the display unit 2 is provided with a plurality of limiting grooves 202, and the inner wall of the protective frame 1 is provided with a plurality of limiting bars 203 at corresponding positions. The limiting grooves 202 and the limiting bars 203 cooperate with each other to limit the position deviation of the display unit 2 in the protective frame 1. The specific connection method is as follows: Figure 3 The width of the limiting groove 202 is slightly greater than the thickness of the limiting bar 203, so that the display unit 2 can be fine-tuned within a certain range without being significantly moved due to external impact.
[0036] In order to further enhance the buffering effect, the present invention further comprises a buffer assembly, which is composed of a plurality of elastic support blocks 501 and a sliding rod 502. Figure 5 and Figure 6 As shown. The elastic support blocks 501 are evenly distributed around the display unit 2, and a cavity is provided inside the elastic support blocks 501. An elastic member 503 is installed inside the cavity, and the two ends of the elastic member 503 are fixedly connected to the top and bottom of the cavity respectively. The sliding rod 502 passes through the elastic support blocks 501 and slides with them. One end of the sliding rod 502 is connected to the back of the display unit 2 by a thread, and the other end is fixedly connected to the inner wall of the protective frame 1 by a limit block. When the display unit 2 is impacted, the elastic support blocks 501 and the sliding rod 502 work together to convert the impact force into compression deformation of the elastic member 503, thereby achieving a multi-level buffering effect.
[0037] The four corners of the protective frame 1 are provided with reinforcement components, which include corner guards 601 and energy absorbing layers 602. The inner side of the corner guard 601 is welded and fixed to the outer surface of the protective frame 1, and the energy absorbing layer 602 covers the outer surface of the corner guard 601. The energy absorbing layer 602 is composed of a multi-layer honeycomb structure, each layer of which has different density and thickness, and can absorb energy in different levels for impacts of different intensities. The layered structure of the corner guard 601 and the energy absorbing layer 602 is as follows: Figure 3 As shown, its installation position is close to the weak area of the protection frame 1, which can significantly improve the overall impact resistance of the protection frame 1.
[0038] Mounting seats are symmetrically provided on both sides of the protective frame 1, and a driving unit 701 is installed on one of the mounting seats, and the output shaft of the driving unit 701 is connected to the first transmission gear 702. A transmission shaft 703 is rotatably connected between the two mounting seats, and one end of the transmission shaft 703 passes through one of the mounting seats and is connected to the second transmission gear 704, and the other end of the transmission shaft 703 is rotatably connected to the inner wall of the protective frame 1 through a bearing. A plurality of groups of soft cams 705 are provided on the transmission shaft 703, and the soft cams 705 are in contact with the back of the display unit 2. The material of the soft cam 705 is silicone, and its surface is smooth and has a certain elasticity to avoid damage to the surface of the display unit 2. The structure of the transmission shaft 703 and the soft cam 705 is as shown in FIG. Figure 4 and Figure 7 As shown, when the driving unit 701 is started, the transmission shaft 703 rotates to drive the soft cam 705 to periodically press the back of the display unit 2, thereby achieving a dynamic shock absorption effect of the display unit 2.
[0039] The back of the display unit 2 is provided with multiple ventilation ducts 801, and a filter is installed inside the ventilation duct 801 to prevent dust and impurities from entering the heat dissipation channel. The ventilation duct 801 is connected to the heat dissipation channel, and a fan 802 is installed inside the heat dissipation channel. The fan 802 is fixed to the inner wall of the protective frame 1 through a bracket, and one end of the ventilation duct 801 is located at the air inlet of the fan 802. The arrangement of the heat dissipation channel and the fan 802 is as follows: Figure 8 As shown, when the fan 802 is not running, the heat generated by the display unit 2 is discharged through the heat conducting sheet 3 and the heat dissipating fins 4; when the fan 802 is running, the external air enters the ventilation pipe 801 through the heat dissipation channel, and quickly dissipates the heat of the internal structure of the display unit 2, thereby achieving an efficient heat dissipation effect.
[0040] The protective frame 1 is internally provided with multiple adjustment mechanisms, including an adjustment screw 901 and an adjustment plate 902. The adjustment screw 901 is rotatably connected to the protective frame 1 via a threaded hole. One end of the adjustment screw 901 passes through the protective frame 1 and is fixedly connected to the adjustment knob. The adjustment plate 902 is threadedly connected to the adjustment screw 901. An elastic pad 903 is provided on one side of the adjustment plate 902, and the elastic pad 903 contacts the back of the display unit 2. The assembly relationship of the adjustment mechanism is shown in FIG. Figure 9 As shown, by rotating the adjustment knob, the adjustment screw 901 drives the adjustment plate 902 to move axially, thereby adjusting the pressure of the elastic pad 903 on the display unit 2 to achieve fine adjustment of the position of the display unit 2.
[0041] A control unit 10 is provided between the protective frame 1 and the display unit 2. This control unit 10 is electrically connected to the drive unit 701 and the fan 802 and is used to adjust the operating state of each component based on changes in the external environment. The control unit 10 incorporates a pressure sensor and a temperature sensor. The pressure sensor monitors the impact force on the display unit 2 in real time, while the temperature sensor monitors the operating temperature of the display unit 2 in real time. When the pressure sensor detects that the impact force exceeds a preset value, the control unit 10 activates the drive unit 701 to rotate the transmission shaft 703, thereby enhancing the shock absorption effect. When the temperature sensor detects that the temperature of the display unit 2 is too high, the control unit 10 activates the fan 802 to accelerate heat dissipation.
[0042] The present invention includes six elastic support blocks 501, distributed along the four sides of the display unit 2 to evenly distribute the impact force. The precise placement of the elastic support blocks 501 ensures that the display unit 2 is evenly impacted when subjected to an impact, preventing damage caused by localized stress concentration.
[0043] The above describes the specific implementation of the present invention, and the connection relationship, position relationship and mutual cooperation relationship between all components have been described in detail to ensure that those skilled in the art can accurately implement the present technical solution according to the contents of the specification.
[0044] In order to better enable relevant personnel in this technical field to fully understand and implement the present invention, the specific implementation principle of the present invention is supplemented below with reference to a specific application scenario.
[0045] First, when the display screen is subjected to external impact, the wavy groove 101 of the protective frame 1 and the elastic filler 102 work together. The elastic filler 102 is embedded in the wavy groove 101 and is made of a highly elastic polymer. When subjected to external force, it can deform and absorb impact energy. The design of the wavy groove 101 increases the surface area of the protective frame 1, making the distribution of the elastic filler 102 more uniform, so that the impact force in different directions can be effectively dispersed. This design is particularly suitable for scenarios where the device falls from a height or is hit from multiple angles, ensuring that the impact force is not concentrated at a single point, causing the protection to fail.
[0046] Secondly, the buffer column 201 between the display unit 2 and the protective frame 1 is connected by a snap-fit structure, and the material of the buffer column 201 is highly elastic rubber. When the display unit 2 is impacted, the buffer column 201 will undergo elastic deformation, transmitting the impact force to the protective frame 1 along its length. Since there is a certain gap between the protrusion at the end of the buffer column 201 and the groove on the inner wall of the protective frame 1, the buffer column 201 can undergo a slight displacement when subjected to force, further alleviating the impact of the impact force on the display unit 2. In addition, the matching design of the limit groove 202 and the limit bar 203 limits the position offset range of the display unit 2, preventing it from being excessively displaced due to impact, while allowing fine-tuning within a certain range to accommodate installation errors.
[0047] Then, when the impact force is large, the buffer assembly composed of the elastic support block 501 and the sliding rod 502 begins to play a role. An elastic member 503 is installed in the cavity inside the elastic support block 501, and the two ends of the elastic member 503 are respectively fixed to the top and bottom of the cavity. When the display unit 2 is impacted, the sliding rod 502 slides in the elastic support block 501 and absorbs the impact energy through the compression deformation of the elastic member 503. This multi-stage buffering mechanism can effectively cope with high-intensity impacts, especially in scenarios where the device is subjected to rapid acceleration changes, such as vehicle bumps or severe vibration environments, and can significantly reduce the damage caused by the impact to the display unit 2.
[0048] The corner protectors 601 and energy-absorbing layer 602 are specifically designed to protect the four vulnerable corners of the protective frame 1. The energy-absorbing layer 602 comprises a multi-layered honeycomb structure, with each layer's density and thickness precisely calculated to provide differentiated energy absorption for impacts of varying intensities. When the display screen is dropped at an angle, the corner protectors 601 and energy-absorbing layer 602 preferentially withstand the impact force. The impact energy is gradually dissipated through the layer-by-layer collapse of the honeycomb structure, protecting the display unit 2 from direct damage.
[0049] The dynamic shock absorption function of the drive shaft 703 and soft cam 705 is particularly important in environments with constant vibration. When the pressure sensor detects that the impact force on the display unit 2 exceeds a preset value, the control unit 10 activates the drive unit 701, rotating the drive shaft 703. The drive shaft 703 drives the soft cam 705 to periodically squeeze the back of the display unit 2. This dynamic squeezing can offset some residual vibration and further reduce the amplitude of the display unit 2's shaking. The soft cam 705 is made of silicone, with a smooth and elastic surface to prevent additional damage to the display unit 2.
[0050] The arrangement of the heat dissipation channel and the fan 802 ensures the stability of the display screen during long-term operation. When the temperature sensor detects that the temperature of the display unit 2 is too high, the control unit 10 starts the fan 802, and the external air enters the ventilation duct 801 through the heat dissipation channel, quickly dissipating the heat from the internal structure of the display unit 2, thereby achieving an efficient heat dissipation effect. The filter inside the ventilation duct 801 blocks the entry of dust and impurities, ensuring the smooth flow of the ventilation duct 801. The air in the protective frame 1 flows through the heat conductive sheet 3 and the heat dissipation fins 4 and is discharged, taking away the heat from the main heating area of the display unit 2. This efficient heat dissipation design is suitable for high-temperature environments or scenarios that require long-term continuous operation, such as outdoor display screens or industrial equipment.
[0051] The adjustment mechanism allows for fine-tuning of the display unit 2's position. By rotating the adjustment knob, the adjustment screw 901 drives the adjustment plate 902 axially, thereby adjusting the pressure exerted by the elastic pad 903 on the display unit 2. This design compensates for positional deviations caused by manufacturing tolerances or long-term use, ensuring that the display unit 2 is always optimally installed.
[0052] In summary, this invention addresses the inadequate protection offered by existing technologies under complex operating conditions through the synergistic effects of a multi-stage cushioning structure, dynamic shock absorption, a highly efficient heat dissipation system, and an intelligent adjustment mechanism. The connections, positions, and coordination between all components are fully detailed to ensure that those skilled in the art can accurately implement this technical solution based on the specifications.
