Description

Technical Field

[0001] The utility model relates to the technical field of power equipment protection, and specifically relates to an anti-seismic buffer rubber shell for power equipment. Background Art

[0002] In the practical application of power equipment, vibration and shock environments are common, such as the continuous operation of industrial equipment, the bumps during transportation, or mechanical vibrations in special scenarios. The outer shells of traditional power equipment expose the following deficiencies when dealing with such environments: Firstly, the performance of the rubber shell material is single, and it is difficult to balance the dual requirements of elastic buffering and structural support. Existing rubber shells mostly adopt single materials, such as ordinary plastics or silica gels. Plastic materials have certain rigidity but insufficient elasticity and cannot effectively absorb vibration energy; although silica gel materials can provide a certain buffering effect, their structural strength is low, and they are prone to deformation during long-term use, and stress concentration problems are likely to occur at the fixing interface with internal components. Secondly, the fixing method of the PCB board is unreasonable. Currently, the PCB board is usually directly fixed to the inner wall of the rubber shell by screws. This rigid connection method causes vibration energy to be directly transmitted to the circuit board. In a vibration environment, the rigid contact between the PCB board and the rubber shell will cause problems such as component solder joint fatigue and circuit breakage. Especially in high-frequency vibration scenarios, the defects of this fixing method are more significant. Content of the Utility Model

[0003] Aiming at the deficiencies of the existing technology, the purpose of the utility model is to provide an anti-seismic buffer rubber shell for power equipment.

[0004] The purpose of the utility model can be realized by the following technical solutions: An anti-seismic buffer rubber shell for power equipment, including a shell, the shell includes a support layer and a buffer layer, the support layer and the buffer layer are integrally formed by composite molding, a support is fixedly arranged inside the support layer, a shock-absorbing airbag is installed on the support, and a bracket is arranged on the shock-absorbing airbag.

[0005] Preferably, the support includes a bottom plate, a connecting plate is vertically arranged on the bottom plate, a support plate is arranged on one side of the upper part of the connecting plate, and an installation hole is formed on the support plate.

[0006] Preferably, the cross-section of the shock-absorbing airbag is in a "king" - shaped structure, including a closed main cavity, auxiliary cavities are arranged at intervals in the length direction of the main cavity, the auxiliary cavities are connected to the main cavity, an independent channel is arranged in the middle of the main cavity, and both ends of the channel are connected to the outside.

[0007] Preferably, the support layer and the buffer layer are integrally formed by secondary injection molding.

[0011] The beneficial effects of this utility model are: by adopting a composite structure design of support layer and buffer layer, the shock resistance performance of the power supply equipment is significantly improved.

[0021] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0022] Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0023] The technical solution of this utility model will be clearly and completely described below with reference to specific embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] See Figures 1 to 7 As shown, the structure of this utility model is as follows: a shock-absorbing and buffering shell for power supply equipment, including a shell 1, the shell 1 including a support layer 101 and a buffer layer 102, the buffer layer 102 being an elastic material for absorbing part of the impact force, and the support layer 101 being a rigid material for supporting the entire shell 1 structure and preventing the shell 1 from deforming when impacted. The support layer 101 and the buffer layer 102 are integrally molded, forming a synergistic force-bearing structure, which avoids the problem of easy delamination and detachment in traditional multi-layer structures, enhances the overall impact resistance through the dispersion of interfacial stress between materials, and simplifies the process. The assembly process improves the structural compactness, while reducing redundant structures, weight, and manufacturing costs. Supports 2 are fixedly installed inside the support layer 101. Multiple supports 2 are fixed inside the support layer 101 by ultrasonic welding or screws. Shock-absorbing airbags 3 are installed on the supports 2, and brackets 4 are installed on the shock-absorbing airbags 3. The PCB board is installed on the brackets 4 by screws. When the power supply equipment is subjected to external vibration or impact, the shock-absorbing airbags 3 buffer the vibration through their own elastic deformation or the elastic medium filled inside, so that the vibration transmitted to the brackets 4 is greatly attenuated, thereby reducing the impact of vibration on the electronic components on the PCB board.

[0025] like Figure 4As shown in the figure, the support 2 includes a bottom plate 201. A connecting plate 202 is vertically provided on the bottom plate 201. On one side of the upper part of the connecting plate 202, there is a support plate 203. An installation hole 204 is provided on the support plate 203. Specifically, the shock-absorbing airbag 3 is snap-fitted in the installation hole 204. The bottom plate 201 is fixed to the support layer 101 by ultrasonic welding or screws, firmly anchoring the shock-absorbing airbag 3 inside the support layer 101. At the same time, a certain floating space is left between the shock-absorbing airbag 3 and the support layer 101 through the connecting plate 202.

[0026] As Figure 5 shown in the figure, the cross-section of the shock-absorbing airbag 3 is in the shape of a "king" character structure, including a closed main cavity 301. The sub-cavities 303 are arranged at intervals in the length direction of the main cavity 301. The sub-cavity 303 is connected to the main cavity 302. An independent channel 302 is provided in the middle of the main cavity 301. Both ends of the channel 302 are connected to the outside. Specifically, two adjacent sub-cavities 303 form grooves 304 on the outer surface of the shock-absorbing airbag 3. One of the grooves 304 is snap-fitted with the support 2, and the other groove 304 is snap-fitted with the bracket 4. At the same time, a bolt is inserted through the channel 302, which not only ensures the stable connection between the shock-absorbing airbag 3, the bracket 4 and the support 2, but also can buffer impacts in multiple directions through the floating spaces of the main cavity 301 and the sub-cavities 303. The support 2, the bracket 4 and the bolt are separated by the sub-cavities 303 to avoid rigid connection.

[0027] Furthermore, the support layer 101 and the buffer layer 102 are integrally formed by secondary injection molding. The support layer 101 and the buffer layer 102 are tightly combined by secondary injection molding to form a composite structure without interface delamination, significantly enhancing the adhesion between the support layer 101 and the buffer layer 102 and the overall anti-peeling performance.

[0028] As Figure 1 、 Figure 2 shown in the figure, a buffer rubber pad 5 is provided on the bracket 4. When the housing 1 is subjected to external vibration, the buffer rubber pad 5 relieves the rigid contact between the bracket 4 and the PCB board through its own elastic deformation, reducing the direct transmission of vibration energy, thereby reducing the risk of solder joint fatigue and component damage. At the same time, when the PCB board is installed on the bracket 4, an elastic rubber ring is provided between the fixing screw and the PCB board to avoid stress concentration.

[0029] As Figure 1 、 Figure 3 shown in the figure, reinforcing ribs 6 are provided on the inner wall of the support layer 101 to further improve the strength of the housing 1.

[0030] As Figure 6As shown, the outer surface of the buffer layer 102 is provided with anti-slip texture 7. The anti-slip texture 7 adopts a geometric structure design with alternating convex and concave surfaces. By increasing the surface roughness, it significantly improves the friction with the external contact surface, thereby enhancing the stability of the shell 1 during use. At the same time, the anti-slip texture 7 can also guide the stress to be evenly distributed, further improving the buffering effect of the buffer layer 102.

[0031] In practical use, when the housing 1 is subjected to external vibration or impact, the buffer layer 102 absorbs part of the impact force through the deformation of its elastic material. At the same time, the support layer 101 prevents the housing 1 from deforming due to its rigid structure. Subsequently, the remaining vibration is transmitted to the shock-absorbing airbag 3 through the support 2. The shock-absorbing airbag 3 further buffers the vibration through its own elastic deformation or the elastic medium filled inside, thereby reducing the impact of vibration on the electronic components on the PCB board. The design of the support layer 101 and the buffer layer 102 being integrally molded together forms a synergistic force-bearing structure. This not only avoids the problem of easy delamination and detachment in traditional multi-layer structures, but also enhances the overall impact resistance through the dispersion of interfacial stress between materials. At the same time, it simplifies the assembly process and improves the structural compactness, reduces redundant structures, and lowers the weight and manufacturing cost of the housing 1.

[0032] The present invention has been further described above with reference to specific embodiments. However, it should be understood that the specific description herein should not be construed as limiting the substance and scope of the present invention. Various modifications made by those skilled in the art to the above embodiments after reading this specification are all within the scope of protection of the present invention.
