Technical Field

[0001] The utility model belongs to the technical field of RV accessories, and particularly relates to a shock absorber device for a water heater. Background Art

[0002] With the rapid development of the RV industry, people's requirements for the stability and practicality of the internal facilities of RVs are increasing day by day. As an indispensable device in RV life, the RV water heater is affected by vibrations generated by road bumps and the like during the driving of the RV. At present, the common shock absorber devices for water heaters on the market mainly include spring shock absorbers, rubber shock absorbers, air suspensions, and the like.

[0003] Among them, the spring shock absorber has problems such as small damping, easy transmission of high-frequency vibrations and easy generation of large noises. At the same time, it is easy to rust in a humid environment, affecting the service life and shock absorption effect; the rubber shock absorber device has a narrow applicable temperature range, poor high-temperature and low-temperature resistance, easy aging when exposed to air or sunlight for a long time, and long-term vibration may also cause the rubber to harden, requiring regular inspection and replacement; the air suspension shock absorber device is expensive, with high maintenance and replacement costs, strict requirements for the cargo tonnage, requires professional technical support for installation and adjustment, and may have problems such as chronic air leakage and unstable air pressure when driving on rough roads for a long time. The increase in the temperature inside the air tank will also affect the accuracy of its pneumatic adjustment.

[0004] The defects of these existing technologies seriously affect the use stability and safety of the RV water heater. Therefore, there is an urgent need for a shock absorber device for a water heater with an optimized structure, convenient maintenance and strong adaptability to solve the above problems. Content of the Utility Model

[0005] The purpose of the utility model is to provide a shock absorber device for a water heater to solve the technical problems such as unreasonable structure, difficult maintenance, poor adaptability and short service life existing in the existing shock absorber device for a water heater, and achieve the goals of improving the stability of the shock absorber device, simplifying the installation process, reducing the maintenance cost and extending the service life.

[0006] To achieve the above purpose, the utility model provides the following technical solutions:

[0007] A shock absorber device for a water heater includes a main body structure, and the main body structure is composed of a back plate fixing bracket, a load-bearing bracket and a buffer gasket;

[0008] The cross-section of the back plate fixing bracket is in a "U" shape, and the back plate fixing bracket is embedded in the RV wall. The back plate fixing bracket is provided with stainless steel studs for cooperating with the load-bearing bracket for installation;

[0009] On both sides of the load-bearing bracket, there are provided two concave arc brackets that fit the outer arc of the water heater to achieve a tight connection between the water heater and the load-bearing bracket;

[0010] The buffer gasket is consistent with the outer arc of the water heater. The buffer gasket is bonded to the concave arc surface of the concave arc bracket, and the inner arc surface of the buffer gasket is completely fitted with the outer arc surface of the concave arc bracket, which is used to avoid the deformation of the shell of the water heater or surface scratches.

[0011] Through the "C"-shaped embedded backplane fixing bracket, the bearing bracket with a concave arc bracket and the buffer gasket that fits the water heater, the stable installation of the water heater is achieved, effectively avoiding the deformation and scratching of the shell, and taking into account the installation convenience and protection effect.

[0012] Preferably, both the backplane fixing bracket and the concave arc bracket are made of 3-mm-thick iron plate material. The 3-mm-thick iron plate material takes into account lightweight while ensuring the structural strength, and meets the requirements of the RV for the weight of accessories.

[0013] Preferably, the bearing bracket includes an upper cross plate, a lower cross plate and a vertical plate that integrally form and connect the upper cross plate and the lower cross plate. The upper cross plate, the lower cross plate and the vertical plate form an "I"-shaped connecting plate. Two concave arc brackets are provided at both ends of the lower cross plate. The "I"-shaped integrally formed connecting plate design and the position setting of the concave arc bracket improve the stability and bearing capacity of the bearing bracket, and ensure a tight connection with the water heater.

[0014] Preferably, two screw holes are opened on the upper cross plate. The screw holes are used for fixed connection with the back of the water heater. The two screw holes can be fixed from the back of the water heater, further enhancing the stability of the installation of the water heater and preventing shaking during driving.

[0015] Preferably, through holes are provided on the lower cross plate corresponding to the stainless steel studs. The backplane fixing bracket and the bearing bracket are fixed together by a countersunk hole screw that passes through the through hole and is threadedly connected to the stainless steel stud. With the cooperation of the stainless steel stud and the countersunk hole screw, a convenient and firm connection between the backplane fixing bracket and the bearing bracket is achieved. The countersunk hole design can also avoid the problem of the screw head protruding.

[0016] Preferably, the connecting plate is made of 10-mm-thick iron plate material. The 10-mm-thick iron plate enables the connecting plate to have stronger bearing and anti-deformation capabilities, and can cope with the weight and vibration impact of the water heater.

[0017] Preferably, the buffer gasket is made of a 10-mm-thick damping strip. The 10-mm-thick damping strip can fully absorb vibration energy, improve the buffering and damping effect, and reduce the impact of vibration on the water heater.

[0018] Preferably, the damping strip is a nitrile rubber damping strip or an ethylene propylene diene monomer (EPDM) rubber damping strip. The nitrile rubber or EPDM rubber material enables the buffer gasket to adapt to different temperature environments and improves the multi-scenario applicability of the device.

[0019] Preferably, vertically equidistant reinforcing ribs are welded between the lower horizontal plate and the load-bearing bracket. These vertically equidistant reinforcing ribs can enhance the connection strength between the lower horizontal plate and the load-bearing bracket, distribute pressure, and prevent the lower horizontal plate from bending and deforming.

[0020] Compared with the prior art, the technical effects and advantages of this utility model are:

[0021] This utility model adopts a pre-embedded installation with a backplate fixing bracket, combined with an "I"-shaped load-bearing bracket and reinforcing ribs, which greatly improves the stability and load-bearing capacity of the overall structure. It can effectively disperse vibration forces, avoid local stress concentration, and cope with various vibrations and impacts during RV travel. At the same time, the precise fit between the concave arc bracket and the shape of the water heater, as well as the double fixing method from the top and bottom, further ensures the stability of the water heater installation.

[0022] This invention uses a threaded connection between stainless steel studs and countersunk screws to fix the backplate mounting bracket and the load-bearing bracket. Installation and disassembly are simple and convenient, requiring no professional technicians. The simplified structural design reduces the number of vulnerable parts, lowering the difficulty and cost of later maintenance. Furthermore, the use of stainless steel studs, high-quality iron plates, and high-performance rubber extends the device's lifespan and reduces replacement frequency.

[0023] The inclusion of cushioning pads effectively prevents deformation and surface scratches on the water heater casing, providing excellent protection. Made of nitrile rubber or EPDM rubber, the cushioning pads can adapt to different temperature environments, enhancing the device's adaptability to various scenarios and meeting the needs of RVs in different regions and under different usage conditions.

[0024] The compact and rational structural design of each component of the device, along with the concealed design of the countersunk screws and the precise fit of each component, makes the overall device more aesthetically pleasing and enhances the visual effect of the RV's interior. At the same time, while ensuring structural strength, the appropriate selection of material thickness balances practicality and lightweight requirements, meeting the design standards for RV accessories.

[0032] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0033] The following is in conjunction with Figures 1 to 6 to make a further detailed description of this application.

[0034] The embodiment of this application discloses a water heater shock absorption device, which includes a main body structure. The main body structure is composed of a backplane fixing bracket 1, a load-bearing bracket 2, and a buffer gasket 3.

[0035] The cross-section of the backplane fixing bracket 1 is in a "U" shape, and the backplane fixing bracket 1 is embedded in the wall of the RV. This embedded installation method can enable the backplane fixing bracket 1 to form a stable connection structure with the RV wall, providing a solid installation foundation for the entire shock absorption device. The backplane fixing bracket 1 is provided with stainless steel studs 11 for cooperating with the load-bearing bracket 2. The stainless steel studs 11 have excellent corrosion resistance and structural strength, which can effectively avoid rusting or breaking during long-term use and ensure the reliability of the connection.

[0036] The backplane fixing bracket 1 is made of an iron plate with a thickness of 3 mm. The iron plate of this thickness can ensure the structural strength while not excessively increasing the overall weight of the device, taking into account both practicality and lightweight requirements, and can well adapt to the strict requirements of the RV for the weight of accessories.

[0037] On both sides of the load-bearing bracket 2, there are two concave arc brackets 21 that fit the arc shape of the water heater 5 to achieve a tight connection between the water heater 5 and the load-bearing bracket 2. The precise fit design between the concave arc brackets 21 and the arc shape of the water heater 5 not only allows the water heater 5 to be stably installed on the load-bearing bracket 2, reducing displacement caused by vibration during driving, but also makes the overall structure more compact and beautiful, improving the visual effect of the RV interior.

[0038] The concave arc bracket 21 is made of 3 mm thick iron plate material, which is consistent with the material thickness of the back plate fixing bracket 1. This facilitates material control during the production and processing process, and also ensures that the concave arc bracket 21 has sufficient load-bearing capacity to cope with the weight of the water heater 5 and the vibration and impact during operation.

[0039] The load-bearing bracket 2 includes an integrally formed upper horizontal plate 22, a lower horizontal plate 23, and a vertical plate 24 connecting the upper horizontal plate 22 and the lower horizontal plate 23. The upper horizontal plate 22, the lower horizontal plate 23, and the vertical plate 24 form an "I"-shaped connecting plate. Two concave arc brackets 21 are located at both ends of the lower horizontal plate 23. The "I"-shaped connecting plate structure design has extremely high structural stability and load-bearing capacity, effectively dispersing the weight and vibration force transmitted from the water heater 5, and avoiding structural damage caused by local stress concentration. The integral molding manufacturing process reduces problems such as loose connections that may occur during assembly, further improving the overall structural strength of the load-bearing bracket 2.

[0040] The connecting plate is made of 10 mm thick iron plate. Compared with the material thickness of the back plate fixing bracket 1 and the concave arc bracket 21, the connecting plate uses a thicker iron plate because the connecting plate, as the core load-bearing component of the load-bearing bracket 2, needs to have stronger load-bearing capacity and resistance to deformation. The 10 mm thick iron plate can fully meet this requirement and ensure that the structure remains stable under the long-term load of the water heater 5 and vibration impact.

[0041] The upper horizontal plate 22 has two screw holes 25, which are used to fix the water heater 5 to the back. By passing screws through the screw holes 25, the water heater 5 is fastened to the upper horizontal plate 22. With the support of the concave arc bracket 21, the water heater 5 can be fixed from both the top and bottom, which greatly improves the stability of the water heater 5 installation and effectively prevents the water heater 5 from shaking during driving.

[0042] The lower horizontal plate 23 is provided with a counterbore through-hole 26 corresponding to the stainless steel stud 11. The backplate fixing bracket 1 and the bearing bracket 2 are fixed together by a counterbore screw 4 passing through the counterbore through-hole 26 and threadedly connected to the stainless steel stud 11. The counterbore design allows the head of the counterbore screw 4 to be embedded inside the lower horizontal plate 23, avoiding space occupation and safety hazards caused by the protrusion of the screw head. At the same time, the threaded connection method makes the installation and disassembly process more convenient, facilitating later maintenance and replacement work.

[0043] Reinforcing ribs 27 arranged vertically at equal distances are welded between the lower horizontal plate 23 and the bearing bracket 2. The arrangement of the reinforcing ribs 27 further enhances the connection strength and structural stability between the lower horizontal plate 23 and the bearing bracket 2, can effectively disperse the pressure borne by the lower horizontal plate 23, prevent problems such as bending deformation of the lower horizontal plate 23 during long-term use, and extend the service life of the bearing bracket 2. The design of the vertical equal-distance arrangement of the reinforcing ribs 27 makes the stress dispersion more uniform and improves the anti-vibration performance of the overall structure.

[0044] The buffer gasket 3 has the same outer arc shape as the water heater 5. The buffer gasket 3 is bonded to the concave arc surface of the concave arc bracket 21, and the inner arc surface of the buffer gasket 3 is completely fitted with the outer arc surface of the concave arc bracket 21, which is used to avoid deformation of the shell of the water heater 5 or surface scratches. The buffer gasket 3 can form a buffer barrier between the water heater 5 and the bearing bracket 2. When the RV is running and generating vibrations, it can effectively absorb the vibration energy and reduce the impact of vibrations on the water heater 5. It not only protects the shell of the water heater 5 from being squeezed and deformed, but also prevents friction scratches between the surface of the water heater 5 and the bearing bracket 2 caused by vibrations, and extends the service life of the water heater 5.

[0045] The buffer gasket 3 is made of a damping strip with a thickness of 10 mm. The 10-mm thickness can ensure that the buffer gasket 3 has sufficient buffer space and damping effect, and can effectively play a buffer role and reduce vibration transmission when facing vibrations of different intensities.

[0046] The damping strip is a nitrile rubber damping strip or an ethylene propylene diene monomer (EPDM) rubber damping strip. Nitrile rubber has good oil resistance, wear resistance and damping performance, while EPDM rubber has excellent weather resistance, high temperature resistance and low temperature resistance. Both materials can meet the requirements of the RV in different usage environments, and users can choose according to the actual usage scenarios and requirements, greatly improving the multi-scenario adaptation ability of the device.

[0047] When installing this device, first embed the backplate fixing bracket 1 with a "U" - shaped cross-section into the RV wall body, ensure that the backplate fixing bracket 1 is firmly connected to the wall body. After the wall structure is stable, check whether the stainless steel studs 11 on the backplate fixing bracket 1 are installed in place without looseness, rust and other conditions.

[0048] Next, the load-bearing bracket 2 is assembled. The upper horizontal plate 22, lower horizontal plate 23, and vertical plate 24 of the load-bearing bracket 2 are integrally formed "I"-shaped connecting plates, and concave arc brackets 21 are fixed at both ends of the lower horizontal plate 23. First, the buffer pads 3 are glued to the concave arc surface of the concave arc brackets 21, ensuring that the inner arc surface of the buffer pads 3 is completely in contact with the outer arc surface of the concave arc brackets 21. During the gluing process, it is necessary to ensure that the gluing is firm to prevent the buffer pads 3 from falling off during use. The buffer pads 3 are made of 10 mm thick nitrile rubber shock-absorbing strips or EPDM rubber shock-absorbing strips, and the appropriate material is selected according to the usage environment of the RV.

[0049] Then, move the load-bearing bracket 2 to the installation position so that the countersunk through holes 26 on the lower horizontal plate 23 correspond one-to-one with the stainless steel studs 11 on the back plate fixing bracket 1. Pass the countersunk screw 4 through the countersunk through holes 26 and thread it to the stainless steel studs 11. Tighten the countersunk screw 4 to fix the back plate fixing bracket 1 and the load-bearing bracket 2 firmly. At this time, the head of the countersunk screw 4 is embedded in the countersunk hole of the lower horizontal plate 23, keeping the surface flat.

[0050] Finally, place the water heater 5 on the concave arc bracket 21 of the load-bearing support 2, so that the arc of the water heater 5 fits tightly with the concave arc bracket 21 and the buffer pad 3. Then, use screws to fix the back of the water heater 5 to the upper horizontal plate 22 through the two screw holes 25 on the upper horizontal plate 22, thus completing the installation of the entire device.

[0051] During use, when the RV vibrates due to ground bumps, the buffer pad 3 will first absorb some of the vibration energy, reducing the direct impact of the vibration on the water heater 5; the "I"-shaped connecting plate structure and the setting of the reinforcing rib 27 can effectively disperse the vibration force and avoid damage to the local structure due to stress concentration; the stable connection between the back panel fixing bracket and the load-bearing bracket and the double fixing method between the water heater and the load-bearing bracket ensure the stability of the water heater in the vibration environment and prevent displacement or falling off.

[0052] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
