[0037] Reference is made below to Figure 1 - Figure 9 Describe the electric control cover plate 100 for a compressor according to an embodiment of the first aspect of the present invention.

[0038] The electric control cover plate 100 for a compressor according to an embodiment of the first aspect of the present invention.

[0039] It should be noted that the compressor device includes: a compressor main body, an electric control box, and an electric control cover plate 100. Among them, the electric control end cover is connected to the electric control box to protect the electric control components. For some existing compressor devices, during operation, due to the inherent characteristics of the compressor, the problems of vibration and noise cannot be fundamentally solved. Therefore, preventing the electric control cover plate 100 from resonating with the compressor has become the core of noise reduction.

[0040] Resonance is a phenomenon in which the vibration amplitude of an object increases at a specific frequency. Therefore, increasing the strength of the electric control cover plate 100 can improve its earthquake resistance ability, reduce the occurrence of noise, avoid the accumulation and amplification of vibration energy at a specific frequency, and thus reduce the generation of noise.

[0041] As Figure 1 - Figure 3 shown, the electric control cover plate 100 includes: a cover plate main body 1 and reinforcing ribs 2.

[0042] The cover plate main body 1 serves as the load-bearing part of the electric control cover plate 100. The reinforcing ribs 2 are arranged on the cover plate main body 1, which can correspondingly increase the local stiffness and overall stability of the electric control cover plate 100. The colloid 3 can improve the vibration damping effect of the electric control cover plate 100 and reduce noise. By arranging the reinforcing ribs 2 and the colloid 3, the strength and stability of the electric control cover plate 100 can be improved, and further the earthquake resistance performance and noise resistance ability of the electric control cover plate 100 can be improved.

[0043] The opposite two sides of the cover plate main body 1 are respectively an outer side surface 11 and an inner side surface 12. The central area of the cover plate main body 1 arches from the inner side surface 12 to the outer side surface 11, so that the outer side surface 11 forms a vault and the inner side surface 12 forms a groove.

[0044] The arched structure can more effectively disperse the external pressure and impact force, and thus can improve the load-bearing capacity of the electric control cover plate 100 and enhance the structural rigidity of the cover plate main body 1.

[0045] Furthermore, the design of forming a vault on the outer side surface 11 is beneficial for drainage, preventing rainwater or residual moisture during cleaning from accumulating on the electric control cover plate 100, and reducing the risk of electrical failures caused by moisture intrusion. At the same time, the vault can also block the accumulation of dust and impurities to a certain extent, keeping the outer surface of the electric control cover plate 100 clean.

[0046] In addition, the design of the vault correspondingly increases the area of the outer surface of the electric control cover plate 100, which is beneficial for the heat generated by the electric control components during operation to be dissipated into the air through heat radiation and convection, improving the heat dissipation efficiency, and helping to maintain the normal working temperature of the electric control components.

[0047] In some alternative embodiments, the shape of the vault formed on the outer side surface 11 can be semi-circular, or rectangular, trapezoidal, any polygon, or the shape of other free-form surfaces to meet different design requirements.

[0048] For example: the vault is a semi-circular vault. The semi-circular vault helps to evenly disperse the forces from all directions, thereby improving the load-bearing capacity of the electronic control cover plate 100.

[0049] Combined with Figure 2 , the thickness of the vault is h, and the value range of h is between 2 mm and 6 mm. Optionally, the thickness h of the vault is 2 mm, 2.5 mm, 3 mm, 4 mm, 5.5 mm, 6 mm, etc. By controlling the thickness h of the vault between 2 mm and 6 mm, the first-order modal value of the electronic control cover plate 100 is optimal.

[0050] The transition angle formed by the vault is r, and the value range of r is between 10° and 30°. Optionally, the transition angle r of the vault is 10°, 15°, 20°, 25°, 30°, etc. When the transition angle r of the vault is between 10° and 30°, the first-order modal value of the electronic control cover plate 100 is optimal.

[0051] The groove formed on the inner side surface 12 provides a certain space for the arrangement of the reinforcing ribs 2. By combining the groove with the reinforcing ribs 2 and the colloid 3, an effective vibration attenuation system can be formed. When the compressor generates vibration, the groove can guide the vibration wave to propagate inside and be gradually absorbed and attenuated by the reinforcing ribs 2 and the colloid 3, thereby reducing the transmission of vibration to the electronic control components and other components. While achieving shock absorption, the electronic control cover plate 100 reduces noise.

[0052] Moreover, the existence of the groove enables the cover plate body 1 to more effectively disperse stress when subjected to external forces, reduce the phenomenon of stress concentration, and improve the anti-deformation ability of the electronic control cover plate 100.

[0053] The reinforcing ribs 2 are located in the groove and connected to the inner side surface 12. They can effectively support and enhance the structural strength of the cover plate body 1 and improve the anti-vibration ability of the electronic control cover plate 100.

[0054] Optionally, the reinforcing ribs 2 are designed to be linear, or the reinforcing ribs 2 are designed to be curved, or the reinforcing ribs 2 can be designed to be zigzag, grid-shaped, and other irregular shapes. The specific shape of the reinforcing ribs 2 can be one of the above shapes or a combination of any of the above shapes, and the specific shape of the reinforcing ribs 2 is adjusted according to the size, shape, and expected load conditions of the electronic control cover plate 100.

[0055] As mentioned in the background art, the reinforcing rib 2 can enhance the structural strength of the electronic control cover 100, but it also constructs cavities inside the electronic control cover 100 that may cause resonance, resulting in increased noise. To solve this problem, the electronic control cover 100 of the present utility model further includes a colloid 3.

[0056] The colloid 3 is located in the groove and connects to the inner side surface 12 and the reinforcing rib 2.

[0057] By filling the colloid 3 in the groove and forming a connection with the inner side surface 12 and the reinforcing rib 2, the cavity rate inside the electronic control cover 100 is reduced, thereby reducing the occurrence of resonance. As a viscoelastic material part, the colloid 3 can not only fill the cavity but also absorb and dissipate energy during vibration, thereby suppressing the amplification of resonance.

[0058] Moreover, the colloid 3 can also improve the overall sound insulation performance of the electronic control cover 100. The colloid 3 is like a barrier, effectively isolating the mechanical noise generated during the operation of the compressor and reducing the transmission of noise to the interior of the vehicle, creating a quieter and more comfortable riding environment for passengers.

[0059] Secondly, the colloid 3 also has certain elastic and damping characteristics. It can deform and consume energy when subjected to an external force. This characteristic enables the colloid 3 to effectively reduce the vibration amplitude and frequency of the electronic control cover 100 in a vibrating environment, absorb part of the noise caused by vibration, and further weaken the noise.

[0060] At the same time, the colloid 3 also plays a certain buffering role between the electronic control component and the cover body 1. When the electronic control component is subjected to impact or vibration, the colloid 3 can absorb part of the impact energy and slow down the impact speed, thereby protecting the electronic control component from damage.

[0061] In addition, the colloid 3 can also form a continuous sealing layer. The sealing layer can effectively reduce the probability of impurities such as dust, moisture, and corrosive gases in the external environment entering the interior of the electronic control box, protecting the electronic control components from damage.

[0062] In addition, when maintenance or replacement is required, the colloid 3 can also be relatively easily removed and replaced. This can also correspondingly reduce the maintenance cost and improve the maintenance efficiency.

[0063] The colloid 3 also has certain electrical insulation properties, which can reduce the risk of short circuit and current leakage.

[0064] As Figure 4 shown, for the electronic control cover 100 of a compressor according to some embodiments of the present utility model, the colloid 3 fills the area in the groove except for the reinforcing rib 2, and the one side surface of the electronic control cover 100 of the compressor is flat on the side of the reinforcing rib 2.

[0065] In this way, the colloid 3 fills the area in the groove except for the reinforcing rib 2 tightly as a filler, which can enhance the structural integrity and sealing performance of the electronic control cover plate 100. Also, through the damping characteristics of the colloid 3, the vibration attenuation ability of the electronic control cover plate 100 is improved.

[0066] On the one hand, the colloid 3 fills the area in the groove except for the reinforcing rib 2, which can remove the air between the groove and the reinforcing rib 2, eliminating the abnormal vibration problem of the electronic control cover plate 100 caused by air vibration. At the same time, the colloid 3 can also absorb sound waves, reducing the number of reflections and the superposition effect of sound waves in the cavity. In this way, the sound waves will gradually attenuate during the propagation process, making the electronic control cover plate 100 exhibit a lower noise level.

[0067] On the other hand, the close cooperation between the colloid 3 and the reinforcing rib 2 forms a stable support structure, enabling the electronic control cover plate 100 to more effectively disperse and absorb stress when subjected to external forces or vibrations, reducing the resonance of the electronic control cover plate 100 and further reducing the spread of noise.

[0068] In addition, the surface of the electronic control cover plate 100 on one side of the reinforcing rib 2 maintains a planar design. This design not only facilitates the installation and fixation of electronic control components but also ensures good contact and cooperation between the electronic control cover plate 100 and other components of the compressor. When the electronic control cover plate 100 is closed, the planar design feature can reduce the contact friction and unnecessary vibrations that may be caused by surface unevenness, thereby reducing the probability of noise caused by mechanical friction.

[0069] In some embodiments as Figure 3 and Figure 4 shown, the part of the inner side surface 12 of the cover plate body 1 surrounding the groove is an annular surface 121.

[0070] The annular surface 121 combines with the groove, providing a stable support platform for the arrangement of the reinforcing rib 2 and also ensuring the tight connection between the reinforcing rib 2 and the cover plate body 1.

[0071] The surface of the reinforcing rib 2 away from the cover plate body 1 is the rib end face 2a, and the surface of the colloid 3 away from the cover plate body 1 is the colloid end face 31. The annular surface 121, the rib end face 2a, and the colloid end face 31 are all flush.

[0072] When the annular surface 121, the rib end face 2a, and the colloid end face 31 are all flush, it is not easy to generate gaps during the assembly between the electronic control cover plate 100 and the electronic control components. It is known that gaps are potential causes of vibration. When the gaps are effectively reduced or eliminated, the vibration transmission path is blocked or restricted, thereby reducing the possibility of vibration energy being transmitted from the compressor excitation source to the electronic control cover plate 100.

[0073] By forming a continuous and smooth transition region between the annular surface 121 and the rib end surface 2a, the stress distribution can be made more uniform, reducing the phenomenon of stress concentration, thereby improving the load-bearing capacity of the electronic control cover 100.

[0074] Specifically, when the electronic control cover 100 is subjected to a force from a certain direction, the continuous and smooth transition region can more effectively disperse these forces and transmit them evenly to the entire structure. This can prevent a local area from being damaged by excessive force and improve the ability of the entire electronic control cover 100 to resist external forces.

[0075] By keeping the glue end surface 31 flush with the annular surface 121 and the rib end surface 2a. The flush glue end surface 31 is used to evenly absorb and disperse vibration energy, thereby improving the seismic and noise reduction performance of the electronic control cover 100.

[0076] According to some embodiments of the present utility model, the electronic control cover 100 for a compressor, as Figure 3 and Figure 5 shown, the reinforcing rib 2 includes: an annular rib 21 and a spoke rib 22.

[0077] Since the main function of the reinforcing rib 2 is to enhance the overall strength, rigidity and stability of the cover. By setting the combination of the annular rib 21 and the spoke rib 22, the supporting strength of the reinforcing rib 2 can be further enhanced.

[0078] The annular rib 21 is located near the center, forming an annular structure. It mainly bears the stress and deformation from the center of the cover, improving the overall stability of the cover. Among them, the cross-sectional shape, size and thickness of the annular rib 21 can be designed according to the force condition of the electronic control cover 100.

[0079] The spoke ribs 22 are multiple and distributed around the annular rib 21. One end of the spoke rib 22 is connected to the annular rib 21 and the other end is connected to the edge of the cover body 1. The main function of the spoke rib 22 is to transmit the supporting force of the annular rib 21 to the edge of the cover, forming a continuous supporting network, further enhancing the rigidity and stability of the electronic control cover 100.

[0080] The number and distribution of the spoke ribs 22 can be designed according to the size, shape and force condition of the electronic control cover 100. Generally speaking, the more the number of the spoke ribs 22 and the more uniform the distribution, the better the rigidity and stability of the electronic control cover 100.

[0081] Optionally, the cross-sectional shape of the rib of the reinforcing rib 2 includes but is not limited to polygons such as rectangles, trapezoids, triangles, etc. The specific cross-sectional shape can be selected according to the force condition and processing convenience.

[0082] In some embodiments, as Figure 3 and Figure 5As shown, the reinforcing rib 2 further includes an inner support rib 23 located within the annular rib 21, and the inner support rib 23 is connected to the annular rib 21.

[0083] As a support structure inside the annular rib 21, the inner support rib 23 can effectively enhance the load-bearing capacity of the annular rib 21, while increasing the stability of the cover plate main body 1 and reducing the resonance phenomenon caused by vibration. It can also disperse the stress to multiple support points to reduce local stress concentration, thereby extending the service life of the cover plate main body 1.

[0084] Among them, the inner support rib 23 and the annular rib 21 can be formed in one processing step. Optionally, the inner support rib 23 and the annular rib 21 are integrally formed parts. Of course, the present invention is not limited thereto, and the inner support rib 23 can also be processed on the basis of the formed annular rib 21, and then the inner support rib 23 is connected to the annular rib 21, as long as the inner support rib 23 and the annular rib 21 are an integrated structure after the overall processing of the reinforcing rib 2.

[0085] Optionally, the connection between the inner support rib 23 and the annular rib 21 is a welded connection, a riveted connection or other connection methods.

[0086] Such as Figure 3 and Figure 5 As shown, in some embodiments, the reinforcing rib 2 further includes a columnar rib 24, and the columnar rib 24 is located between the annular rib 21 and the edge of the cover plate main body 1.

[0087] The shape between the annular rib 21 and the edge of the cover plate main body 1 is relatively complex and the area is small. At this time, by setting the columnar rib 24, the distribution of stress can be guided, and the stress concentration area can be strengthened, thereby improving the strength and stiffness of this area.

[0088] According to some embodiments of the present invention, for the electric control cover plate 100 of a compressor, the reinforcing rib 2 includes a plurality of strip-shaped ribs 25, and the width of the strip-shaped rib 25 in the central area is greater than the width of the strip-shaped rib 25 in the edge area.

[0089] Considering that the central area of the electric control cover plate 100 may bear greater stress and load, setting the wider strip-shaped rib 25 in the central area can provide a larger cross-sectional area, thereby increasing the bending and shear resistance of the central area of the electric control cover plate 100. When the electric control cover plate 100 is subjected to external pressure or vibration, the wide strip-shaped rib 25 in the central area can more effectively disperse and absorb these forces, reduce the occurrence of resonance, and reduce noise. In addition, the wide strip-shaped rib 25 can also enhance the overall stiffness of the cover plate, so that it can remain stable under various working conditions.

[0090] Compared with the central region, the strip-shaped ribs 25 in the edge region are configured to have a relatively narrow size, considering that the stress application mode in the edge region may be different from that in the central region. The narrower strip-shaped ribs 25 can more flexibly adapt to structural deformation in the edge region, while reducing the material usage and cost.

[0091] According to some embodiments of the present utility model, the electric control cover plate 100 for a compressor, as Figure 3 , Figure 5 and Figure 6 shown, a plurality of connection holes 13 are provided at intervals on the edge of the cover plate main body 1, and connection holes 13 are provided at the corners of the edge of each cover plate main body 1.

[0092] By providing the connection holes 13, it is ensured that the electric control cover plate 100 can be easily aligned and fastened during installation, thereby improving the stability and reliability of the overall structure.

[0093] Especially at the corners of the edge of each cover plate main body 1, connection holes 13 are also provided. Considering that the corners are often areas of stress concentration and are easily affected by external forces. By providing connection holes 13 at the corners, the connection strength at the corners can be further enhanced, so that the electric control cover plate 100 can remain stable and not loose when subjected to external force impact or vibration. At the same time, the connection holes 13 at the corners also provide an operating space for installation and disassembly, making the maintenance and replacement work simpler and faster.

[0094] The connection holes 13 can be compatible with different types of fasteners. For example: bolts, pins, rivets or other types of fasteners. Optionally, an internal thread structure is formed in the connection holes 13. By providing the internal thread structure, fasteners with external threads such as bolts can be directly screwed into the connection holes 13 to achieve fast and firm connection, simplifying the connection process.

[0095] In order to improve the connection effect of the electric control cover plate 100. Combining Figure 7 , the inventor team analyzed the free mode of the electric control cover plate 100, determined its edge vibration situation, and extracted the first six modes. The highlighted areas in the figure are the places with larger vibration values. Therefore, connection holes 13 are provided at the positions with larger vibration. These connection holes 13 can achieve the connection effect between the electric control cover plate 100 and other components, and also effectively suppress the vibration amplitude of these areas through the connection of fasteners.

[0096] In some embodiments, the distance from the center of the connection hole 13 to the edge of the cover plate main body 1 is 3 mm - 8 mm. For example: the distance from the center of the connection hole 13 to the edge of the cover plate main body 1 can be 3 mm, 4 mm, 5 mm, 7 mm, 8 mm, etc.

[0097] Combining Figure 8 , Figure 8For the inventor team to conduct a constrained modal analysis on the electronic control cover plate 100, the modal frequency of the electronic control cover plate 100 and the weak points of the cover plate are determined through the analysis, and the reinforcing rib 2 is set at the weak points of the cover plate. The setting position of the reinforcing rib 2 is as shown in Figure 3 , Figure 5 . Specifically, the annular rib 21 provides a stable framework for the electronic control cover plate 100, effectively resisting bending and torsional loads from multiple directions and reducing the deformation of the overall structure. The spoke ribs 22 radiate from the center outwards like the cables of a bridge, enhancing the connection between the central area and the edge of the cover plate, dispersing the stress concentration, and avoiding damage caused by local excessive stress. The setting of the internal support rib 23 strengthens the internal support structure of the cover plate. The columnar ribs 24 and the strip ribs 25 are arranged according to the specific stress distribution. They not only serve as local strengthening means but also play a role in connecting and transmitting loads in the overall structure. By setting the distribution of the reinforcing rib 2 through modal analysis, the structural strength problem of the electronic control cover plate 100 in a dynamic environment can be scientifically solved, and the long-term stable use of the electronic control cover plate 100 can be realized.

[0098] According to the compressor device of the second aspect embodiment of the present utility model, it includes: a compressor main body, an electronic control box, and an electronic control cover plate 100.

[0099] Among them, the electronic control box is used to connect the compressor main body. The electronic control cover plate 100 is used to connect the electronic control box, and the electronic control cover plate 100 is the electronic control cover plate 100 for the compressor of the first aspect embodiment of the present utility model.

[0100] The electronic control box is responsible for receiving external control signals and controlling the compressor main body according to a preset program. A variety of electronic components and control circuits are integrated inside the electronic control box. Therefore, the electronic control cover plate 100 can achieve the functions of sealing and protecting the electronic control box, ensuring the good working state of the internal components of the electronic control box.

[0101] At the same time, by setting the electronic control cover plate 100 of the first aspect embodiment of the present utility model, the vibration energy from the compressor main body can also be effectively dispersed and absorbed, which helps to reduce the overall vibration level of the compressor device, thereby reducing noise and vibration and improving the running smoothness and reliability.

[0102] This electronic control cover plate 100 not only has excellent electrical insulation performance but also improves the strength and stability of the overall structure through the ingenious design of the reinforcing rib 2.
