Description

TECHNICAL FIELD

[0001] The utility model relates to a damping connection structure, especially to a connection structure applied to an electric appliance, used for connecting two components and having a damping function. BACKGROUND

[0002] In an electric appliance, especially a device with a vibration source (such as an air conditioner, a washing machine, etc.), it is often necessary to establish a connection between two components while isolating or weakening the vibration generated by the vibration source to prevent the vibration from being transmitted to other parts of the device, causing noise, structural fatigue, or even damage.

[0003] Taking a window air conditioner as an example, the motor is usually fixed in the window frame by a motor support. The upper part of the motor support is usually provided with an electric control box. Since the electric control box has a relatively large structure, only the side edge is usually fixed to the frame. In order to enhance the stability of the structure, a support rod extending upward from the motor support is often used to support the electric control box in the prior art.

[0004] However, the vibration generated by the motor during operation will be transmitted through the motor support. In the prior art, in order to prevent the connection between the motor support and the electric control box from loosening due to vibration, a bolt is usually used to rigidly fix the support rod and the connecting seat on the bottom surface of the electric control box. Although this rigid connection avoids the risk of loosening, it directly transmits the vibration of the motor to the electric control box, causing the electric control box to vibrate, generate noise, and possibly affect the service life of the electronic components in the electric control box.

[0005] Therefore, how to effectively isolate or weaken the vibration while ensuring the connection strength is an important problem to be solved in the design of electric appliances. Especially for compact devices that are sensitive to noise and vibration (such as window air conditioners), the requirements for damping connection structures are higher. SUMMARY

[0006] The utility model aims at providing a damping connection structure to solve the problem of vibration transmission caused by rigid connection between components in the prior art. Another purpose of the utility model is to provide a window air conditioner using the damping connection structure.

[0007] To achieve the above-mentioned purposes, the utility model adopts the following technical solutions:

[0008] The utility model provides a kind of shock-absorbing connection structure, applied to window machine air conditioner, including the first connecting seat fixed to the top of motor support of window machine air conditioner and the second connecting seat fixed to the bottom surface of electric control box of window machine air conditioner, it is characterized by: the first connecting seat and the second connecting seat are connected by rubber column, the top surface of the first connecting seat is equipped with first connecting hole, the bottom surface of the second connecting seat is equipped with second connecting hole, the first end of the rubber column is inserted into the first connecting hole and is interference fit with first connecting hole, the second end of the rubber column is inserted into the second connecting hole and is interference fit with second connecting hole.

[0009] By adopting rubber column as connecting piece, the elasticity of rubber material itself can be used to effectively absorb and attenuate vibration. The interference fit plug-in connection mode makes installation and disassembly more convenient.

[0010] Further, the first connecting hole is equipped with positioning column, the positioning column is coaxially arranged with the first connecting hole, the central position of the end face of the first end of the rubber column is equipped with blind hole matched with the positioning column, and the positioning column is plugged into the blind hole.

[0011] The cooperation of positioning column and blind hole can facilitate the installation and positioning of rubber column, ensure the accuracy of connection, and the existence of positioning column can improve the supporting performance of rubber column and prevent excessive lateral displacement of rubber column under stress.

[0012] Further, the first connecting seat includes a first fixed seat connected thereto, and the first connecting hole is formed in the top surface of the first fixed seat; the second connecting seat includes a second fixed seat connected thereto, and the second connecting hole is formed in the bottom surface of the second fixed seat.

[0013] The design of fixed seat can better realize the connection of shock-absorbing connection structure and external structure, make the whole shock-absorbing connection structure more stable, and effectively realize the shock-absorbing connection effect.

[0014] Further, the first connecting hole is composed of a plurality of first fins uniformly distributed in a ring direction, each of the first fins is vertically arranged, and one end of the first fin is connected to the first fixed seat; the second connecting hole is composed of a plurality of second fins uniformly distributed in a ring direction, each of the second fins is vertically arranged, and one end of the second fin is connected to the second fixed seat.

[0015] The interference fit of the connecting hole composed of fins and the rubber column changes the contact form between the connecting seat and the rubber column from typical surface contact to multiple point or line contact. This design increases the stress concentration at the contact site, so that the rubber column is more likely to locally elastically deform under vibration, thereby reducing the vibration of the whole rubber column and more effectively absorbing and attenuating vibration.

[0016] Further, the projections of the plurality of first fins and the plurality of second fins on the top surface of the first fixing base are spaced apart.

[0017] The design of the spaced-apart fins causes different forces to be applied to the rubber column by the fins of the first connecting base and the second connecting base when the first connecting base is laterally displaced due to vibration, thereby facilitating torsional deformation of the rubber column.

[0018] The utility model further provides a window air conditioner, including motor support and electric control box, motor support and electric control box are connected through preceding and following shock attenuation connection structure.

[0019] The shock attenuation connection structure is applied to the window air conditioner, which can effectively isolate the vibration generated by the motor, reduce the vibration and noise of the electric control box, and improve the overall performance and service life of the window air conditioner.

[0020] Further, the first connecting base is integrally formed with the motor support, and the second connecting base is integrally formed with the electric control box.

[0021] The integrally formed injection molding simplifies the manufacturing process, reduces the production cost, and ensures the connection strength between the connecting base and the motor support and the electric control box.

[0022] In summary, the shock attenuation connection structure uses a rubber column as a connecting piece, effectively absorbs and attenuates vibration by using the elastic properties of the rubber material, and avoids the problem of vibration transmission caused by rigid connection. The design of the positioning column not only facilitates installation and positioning, but also improves the support performance of the rubber column. The interference fit of the fin structure and the rubber column, as well as the design of the spaced-apart fins, makes the connecting part more prone to elastic deformation, especially torsional deformation, thereby more effectively absorbing vibration energy and improving the shock attenuation effect. In addition, since the plug-in connection method is used, the shock attenuation connection structure of the utility model is more convenient and fast during assembly and later maintenance and replacement, thereby reducing maintenance costs. The shock attenuation connection structure is applied to the window air conditioner, which can significantly reduce the impact of motor vibration on the electric control box, reduce noise, and improve the overall performance and service life of the machine. At the same time, the integrally formed injection molding manufacturing method simplifies the process and reduces costs. The shock attenuation connection structure of the utility model is not only suitable for window air conditioners, but also can be widely applied to other electrical equipment or mechanical structures that require shock attenuation connection, and has good versatility and practicality.

[0028] The preferred embodiments of the present application are described below in conjunction with the accompanying drawings, which should be understood as merely illustrative and explanatory, and not restrictive of the present application.

[0029] Example 1.

[0030] As shown in Figures 1-3 , the present embodiment provides a damping connection structure applied to a window air conditioner, which comprises a first connecting seat 1 and a second connecting seat 2. Generally, the first connecting seat 1 is fixed to the top of the motor support 4 of the window air conditioner through a first fixing seat 13. The second connecting seat 2 is fixed to the bottom surface of the electric control box 5 of the window air conditioner through a second fixing seat 22, and is arranged oppositely in an up-down manner. The first connecting seat 1 and the second connecting seat 2 are connected through a rubber column 3, and the two ends of the rubber column 3 are respectively connected to the first connecting seat 1 and the second connecting seat 2 in a plug-in manner.

[0031] The top surface of the first fixing seat 13 is provided with a positioning column 11 protruding towards the rubber column 3. The center of the end surface of the rubber column 3 matched with the first fixing seat 13 is provided with a blind hole 31 matched with the positioning column 11. The matching design of the positioning column 11 and the blind hole 31 enables the rubber column 3 to be accurately positioned during installation, and the positioning column 11 can provide additional support when subjected to external force, preventing excessive lateral displacement of the rubber column 3.

[0032] The first fixing seat 13 and the second fixing seat 22 are both composed of vertically arranged fin-shaped circular structures uniformly distributing the connecting holes. Specifically, a plurality of vertical first fins 12 surround the first connecting hole on the first fixing seat 13, and one end of the first fin 12 is connected to the first fixing seat 13; a plurality of vertical second fins 21 surround the second connecting hole on the second connecting seat 2, and one end of the second fin 21 is connected to the second fixing seat 22. The rubber column 3 is in interference fit with the two connecting holes. This design makes the contact form between the first connecting seat 1 and the second connecting seat 2 and the rubber column 3 be a plurality of point or line contacts, increasing the stress concentration at the contact site, so that the rubber column 3 can be elastically deformed under smaller vibration, thereby more effectively absorbing and attenuating vibration.

[0033] Further, as shown in Figure 3 The projections of the first fin 12 and the second fin 21 on the bottom surface of the first fixing seat 1 are arranged in a spaced manner. This spaced arrangement makes the first fin 12 and the second fin 21 generate different direction forces on the rubber column 3 when the first connecting seat 1 is laterally displaced due to vibration, so as to promote the rubber column 3 to be torsionally deformed, thereby more effectively absorbing vibration energy.

[0034] Embodiment 2.

[0035] As shown in Figure 4 , 5 The embodiment provides a window air conditioner, which comprises a motor support 4 and an electric control box 5. The motor support 4 and the electric control box 5 are connected through the damping connection structure described in embodiment 1.

[0036] Specifically, the first connecting seat 1 is arranged on the top of the motor support 4 in a one-piece forming manner, and the second connecting seat 2 is arranged on the bottom surface of the electric control box 5 in a one-piece forming manner. This one-piece injection molding manner simplifies the manufacturing process, reduces the production cost, and ensures the connection strength between the connecting seat and the motor support 4 and the electric control box 5.

[0037] When the window air conditioner is working, the vibration generated by the motor is transmitted to the first connecting seat 1 through the motor support 4. Since the first connecting seat 1 and the second connecting seat 2 are connected through the rubber column 3, the rubber column 3 can absorb and attenuate most of the vibration energy, thereby reducing the vibration transmitted to the electric control box 5. At the same time, the fin structure and the spaced arrangement design further enhance the damping effect, so that the vibration and noise of the electric control box 5 are effectively controlled.
