Description

Technical Field

[0001] This utility model belongs to the field of display vibration reduction technology, specifically relating to a liquid crystal display vibration damping device. Background Technology

[0002] In the RV industry, LCD displays are crucial information display and entertainment devices, and their installation stability directly impacts user experience and device lifespan. Since RVs often operate on unpaved or rugged roads, the continuous vibrations generated during travel can easily cause LCD displays to shift, loosen components, or even be damaged. Therefore, specialized shock absorption devices are needed to secure and protect the displays. Currently, various technologies have been developed for RV LCD display shock absorption devices, including spring-type, hydraulic, airbag-type, and composite types. These devices achieve shock absorption based on different principles and are used to varying degrees in RV production and modification. Spring-type devices are widely used in entry-level RVs due to their simple structure and low cost, while airbag-type and composite types are gradually being promoted in the mid-to-high-end RV market due to their superior shock absorption performance.

[0003] Existing spring-type shock absorbers have significant performance shortcomings. In high-frequency vibration scenarios, the steel wires of their core component, the spring, can directly transmit vibrations, causing the display to sway. This not only affects the viewing experience but also accelerates component wear. Furthermore, springs are weak in resisting environmental pollution and low-temperature changes, and are prone to corrosion and elasticity loss after long-term use, resulting in a short lifespan and requiring frequent replacement to maintain shock absorption effectiveness. While hydraulic shock absorbers can better control vibration amplitude, the hydraulic system carries the risk of leakage. Once a leak occurs, not only does the shock absorption performance decrease significantly, but professional repairs are also required, leading to high maintenance costs. Moreover, this device requires stringent installation and adjustment precision; any deviation during installation will directly affect the shock absorption performance, making it difficult to meet the stability requirements of the complex driving environment of a motorhome.

[0004] While airbag and composite shock absorbers offer performance improvements, key issues in use and maintenance remain unresolved. The core component of airbag shock absorbers, the airbag itself, is made of rubber, making it susceptible to aging and cracking under prolonged exposure to vibration and temperature changes, requiring regular inspection and replacement. The system comprises multiple components, including the airbag, inflation pump, and control system; failure in any component can lead to overall performance failure, resulting in high repair difficulty and cost. Furthermore, during extended driving on rough roads, issues such as chronic air leakage, unstable air pressure, and elevated temperatures within the air tank can arise, compromising stability. Composite shock absorbers, due to their complex structure, are not only expensive to manufacture but also require specialized technicians for installation and adjustment, demanding specific construction conditions. Post-installation maintenance requires regular inspection and upkeep of multiple different types of components, making the process cumbersome. Repair costs in case of malfunction are significantly higher than other types of devices, hindering widespread adoption in the RV market. Utility Model Content

[0005] The present invention aims to address the shortcomings of existing RV LCD display shock absorption devices in terms of material strength, cushioning and protection, installation flexibility, overall robustness, and post-maintenance costs, such as the technical problems of springs transmitting high-frequency vibrations, easy hydraulic leakage, easy aging of airbags, and complex and costly composite structures.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A shock absorption device for a liquid crystal display includes:

[0008] The iron plate bracket uses U-shaped positioning grooves I and II to mount buffer pads I and II.

[0009] Both the left and right brackets are L-shaped structures and are installed on the left and right sides of the iron plate bracket as side-mounted load-bearing brackets to increase the stability of the RV's LCD display shock absorber.

[0010] The galvanized square tube is installed in the U-shaped positioning groove Ⅲ on the iron plate bracket. The bottom of the galvanized square tube is provided with an elongated oval hole for fixing to the wall and adjusting the installation position.

[0011] The hook is composed of a round steel bar, a fixing lug, and a base. The base is fixed to the wall, and the round steel bar is connected to the mounting groove at the top of the galvanized square tube to help fix the galvanized square tube, making the connection between the galvanized square tube and itself and the wall more stable and preventing it from falling off as a whole.

[0012] As a preferred option, the iron plate bracket is made of 2 mm iron plate material, which can effectively improve the overall structural strength and provide a stable load-bearing foundation for the installation of various components.

[0013] Preferably, both buffer pad I and buffer pad II are made of foam board, with buffer pad I being bonded to U-shaped positioning groove I and buffer pad II being bonded to U-shaped positioning groove II. U-shaped positioning groove II is located inside the U-shaped positioning groove I on both sides. The opening direction of U-shaped positioning groove III is opposite to that of U-shaped positioning groove I and U-shaped positioning groove II. The use of foam board for the buffer pads and their corresponding bonding to specific U-shaped positioning grooves with the opening direction of U-shaped positioning groove III being opposite not only achieves precise positioning of the buffer pads to prevent displacement and enhances buffer protection, but also adapts to the installation requirements of galvanized square tubes.

[0014] Preferably, the iron plate bracket has vertically equidistant mounting holes on both sides, and vertically equidistant waist holes on both the left and right brackets. The left and right brackets are fixed to the iron plate bracket by screws that pass through the waist holes and are screwed into the mounting holes. The iron plate bracket has vertical mounting holes, and the left and right brackets have vertical waist holes and are fixed by screws. The connection position of the brackets can be flexibly adjusted to adapt to different installation scenarios and ensure the connection is firm.

[0015] Preferably, a square tube pad is embedded and fixed on the iron plate bracket. The galvanized square tube is fixed to the iron plate bracket by bolts that pass through the galvanized square tube and are screwed to the square tube pad. The iron plate bracket is fitted with a square tube pad and the galvanized square tube is fixed on it by bolts, which can enhance the connection stability between the galvanized square tube and the iron plate bracket and avoid direct contact and wear between the two.

[0016] Preferably, there are two fixing ears, which are integrally formed on both sides of the base, and a round steel is integrally formed between the two fixing ears. The base is used for fixed connection with the wall.

[0017] The galvanized square tube is attached to the round steel of the hook through the mounting groove on it, so that the galvanized square tube and the hook are not easy to fall off as a whole. The hook component is integrally formed, the base is fixed, and the galvanized square tube is attached to the round steel, which improves the strength of the hook itself and the stability of the connection between the galvanized square tube and the hook, and prevents the whole thing from falling off.

[0018] Compared with the prior art, the technical effects and advantages of this utility model are:

[0019] (1) In this utility model, the core bearing iron plate bracket can provide a stable installation foundation for each component, and the side-mounted left and right brackets further enhance the overall stability, avoiding the defects of the existing spring type which is prone to transmitting vibration due to material problems and the airbag type which is prone to aging and cracking, thus extending the overall service life of the device and reducing the need for frequent replacement due to component damage.

[0020] (2) The adjustable fixing structure of the galvanized square tube and the adjustable connection between the left and right brackets and the iron plate bracket make the device no longer limited to a fixed installation point. It can flexibly adjust the installation position and status according to actual needs, adapt to different RV installation scenarios, and does not require professional personnel to carry out complex installation and debugging like hydraulic and composite types, thus reducing the installation difficulty and requirements for construction conditions.

[0021] (3) The specially designed buffer structure of this utility model can effectively absorb vibration, reduce damage to the LCD display and the device itself, and avoid the problems of high-frequency vibration transmission of existing spring type and leakage of hydraulic type affecting the protection effect. At the same time, the overall structure of the device is simplified and the components are reliably connected. Unlike airbag type and composite type, there is no need to frequently check and maintain multiple complex components in the later stage, which greatly reduces the difficulty and cost of maintenance and improves the cost-effectiveness of use.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] The following combination Figures 1 to 6 This application will be described in further detail;

[0031] This application discloses a shock absorption device for a liquid crystal display, including an iron plate bracket 10, a left side bracket 8 and a right side bracket 9, a galvanized square tube 7 and hooks. The iron plate bracket 10 plays a core role in bearing and positioning, and can install the galvanized square tube 7, the left side bracket 8 and the right side bracket 9. It can also be further fixed by the square tube pad 3. The left side bracket 8 and the right side bracket 9 are both L-shaped side-mounted load-bearing brackets, which are fixed on the left and right sides of the iron plate bracket 10 respectively. The connection position can be adjusted to enhance the overall stability of the shock absorption device. The top of the galvanized square tube 7 can cooperate with the hook, and the bottom can be fixed to the wall and the installation position can be adjusted. It can connect the wall and the iron plate bracket 10 to help fix the entire device. The hook is fixed to the wall to help fix the galvanized square tube 7 to prevent the whole device from falling off.

[0032] The iron plate bracket 10, left side bracket 8, right side bracket 9, galvanized square tube 7, and hooks in the overall structure of the device have clear division of labor and are closely connected. The iron plate bracket 10 can support the core components, the left side bracket 8 and the right side bracket 9 can enhance the sturdiness, and the galvanized square tube 7 and hooks can achieve flexible fixation to the wall. The whole device takes into account load-bearing capacity, fixation and multi-scene adaptability, effectively ensuring the stable installation of the LCD monitor.

[0033] The iron plate bracket 10 is provided with U-shaped positioning grooves I11 and II12, which are respectively used to install and position the buffer pads I1 and II2. The U-shaped positioning grooves II12 are located inside the U-shaped positioning grooves I11 on both sides. Both the buffer pads I1 and II2 are made of foam board to increase cushioning and reduce the damage to the RV LCD display shock absorber. The buffer pads I1 and II2 are respectively bonded to the U-shaped positioning grooves I11 and II12. The iron plate bracket 10 is made of 2 mm iron plate material to increase the overall structural strength.

[0034] U-shaped positioning grooves I11 and II12 can accurately position the buffer pad and prevent it from shifting. The foam layer buffer pad can directly absorb vibration, reducing damage to the monitor and shock absorber. In addition, the 2mm iron plate material greatly improves the strength of the bracket itself and extends the overall service life of the device.

[0035] The thickness of buffer pad I1 and buffer pad II2 is 5-15mm, and the surfaces of buffer pad I1 and buffer pad II2 are smooth and protrude from the iron plate bracket 10 to reduce frictional damage when in contact with the LCD monitor; the thickness of 5-15mm can balance the buffering effect and the installation space, avoiding excessive thickness that takes up space or insufficient buffering that is too thin; the smooth surface can reduce friction when in contact with the LCD monitor and prevent the monitor casing from being damaged by friction.

[0036] The left bracket 8 and the right bracket 9 are installed on the left and right sides of the iron plate bracket 10 as side-mounted load-bearing brackets to increase the stability of the RV LCD display shock absorber.

[0037] The iron plate bracket 10 has mounting holes 13 arranged vertically at equal intervals on both sides. The left bracket 8 and the right bracket 9 are L-shaped structures, and the left bracket 8 and the right bracket 9 have waist holes 14 arranged vertically at equal intervals. The left bracket 8 and the right bracket 9 are fixed to the iron plate bracket 10 by screws that pass through the waist holes 14 and are screwed to the mounting holes 13. The connection position between the left bracket 8, the right bracket 9 and the iron plate bracket 10 can be adjusted by the cooperation of the waist holes 14 and the mounting holes 13 to adapt to the requirements of the overall height and stability of the shock absorption device in different installation scenarios.

[0038] The L-shaped structure adapts to side-mounting requirements and enhances the lateral load-bearing capacity of the device; the cooperation between the waist hole 14 and the mounting hole 13 allows for flexible adjustment of the position of the bracket on the iron plate bracket 10, which can not only adapt to different height installation requirements, but also further optimize the overall stability of the device and meet diverse installation scenarios.

[0039] The galvanized square tube 7 is installed in the U-shaped positioning groove Ⅲ15 on the iron plate bracket 10, and the opening direction of the U-shaped positioning groove Ⅲ15 is opposite to the opening direction of the U-shaped positioning groove Ⅰ11 and the U-shaped positioning groove Ⅱ12. The iron plate bracket 10 is provided with a square tube pad 3 embedded and fixed. After the galvanized square tube 7 is inserted into the U-shaped positioning groove Ⅲ15, the galvanized square tube 7 is fixed on the iron plate bracket 10 by bolts that pass through the galvanized square tube 7 and are screwed to the square tube pad 3.

[0040] The U-shaped positioning groove Ⅲ15 can quickly pre-position the galvanized square tube 7, making installation convenient; the square tube pad 3 can enhance the stability of the bolt connection, avoid wear caused by direct contact between the galvanized square tube 7 and the iron plate bracket 10, and at the same time improve the firmness of the connection between the two to prevent loosening.

[0041] The bottom of the galvanized square tube 7 is provided with an elongated oval hole 16. The galvanized square tube 7 is fixed to the wall by screws passing through the elongated oval hole 16. The gap and distance can be adjusted according to the actual situation through the elongated oval hole 16. Both ends of the galvanized square tube 7 are laser-cut, and the top of the galvanized square tube 7 is cut with an installation groove 17 that matches the shape and size of the hook, so as to achieve a perfect fit with the hook accessories, reduce the movement gap and make it more secure.

[0042] The elongated oval hole 16 allows for flexible adjustment of the gap and distance with the wall during installation, adapting to different wall installation position deviations; the laser-cut mounting groove 17 can precisely match the hook, reducing the gap between movement and preventing the galvanized square tube 7 from loosening its connection with the hook, thus improving the overall fixing stability.

[0043] The hook is composed of round steel 4, fixing ears 5, and base 6. The base 6 is used to fix it to the wall. The fixing ears 5 are integrally formed on both sides of the base 6. The round steel 4 is integrally formed between the two fixing ears 5. The galvanized square tube 7 is hung on the round steel 4 of the hook through the mounting groove 17 on it.

[0044] The integrally formed round steel 4, fixing ear 5 and base 6 structure enhance the strength of the hook itself, making it less prone to breakage; the base 6 is fixed to the wall and the round steel 4 is hung on the galvanized square tube 7 to form a double fixation (in conjunction with the screws at the bottom of the galvanized square tube 7), further preventing the galvanized square tube 7 from falling off and ensuring the overall installation safety of the device.

[0045] The core components of this LCD monitor shock absorption device have clearly defined functions and are tightly connected. The iron plate bracket 10, made of high-strength material, supports the core components and precisely fixes the foam buffer pad through a specific U-shaped positioning groove. The buffer pad effectively absorbs vibrations and reduces friction on the monitor and damage to the shock absorber. The adjustable connection of the L-shaped left and right brackets enhances lateral stability to adapt to various installation scenarios. At the same time, the galvanized square tube 7 is firmly connected to the iron plate bracket 10 through the pre-positioning groove and the square tube pad 3. It can also flexibly adjust the wall installation position through the elongated oval hole 16, and precisely match the laser-cut groove and the one-piece molded hook. With the double fixing structure of the hook, a reliable connection between the device and the wall is achieved. The whole device takes into account load-bearing capacity, buffer protection, multi-scenario adaptability and low maintenance requirements, effectively ensuring the stability of the LCD monitor installation and extending the service life of the device.
