The compressor is a fluid machine that raises a low-pressure gas to a high-pressure gas, and is the heart of a refrigeration system. The refrigerating cycle is powered by sucking low-temperature and low-pressure refrigerant gas from the air suction pipe, driving the piston to compress the refrigerant gas through the operation of the motor, and discharging high-temperature and high-pressure refrigerant gas to the exhaust pipe.

The compressor will operate at a high frequency during operation and produce a small amplitude of circumferential vibration. The conventional wiring method of the terminal of the compressor is to electrically connect the driving plate with the terminal of the compressor through a wire.

Disclosure of Invention

According to a first aspect of the present disclosure, a modular circuit board is provided. The combined circuit board comprises a first circuit board which is provided with a jack which is suitable for being directly matched and connected with a binding post of vibration type equipment; and a second circuit board electrically connected with the first circuit board via a flexible conductive member so as to supply power to the post of the vibration-type apparatus via the first circuit board; wherein the flexible conductive member is arranged to enable the first circuit board to vibrate by a certain magnitude independently of the second circuit board. The design of the combined circuit board allows the combined circuit board to be directly matched and connected with a binding post of the vibration type equipment, and simultaneously, the influence of the vibration type equipment on important parts on the combined circuit board is avoided.

According to some embodiments of the present disclosure, the first circuit board and the second circuit board are each rigid circuit boards. In such embodiments, the rigid circuit board may provide rigid support directly for the circuit components thereon.

According to some embodiments of the present disclosure, the first circuit board and the second circuit board are complementary in shape. In these embodiments, the first circuit board and the second circuit board may thus be formed by cutting the same integrated circuit board. In this application, the term "complementary" means that the contour of one of the two shapes can substantially conform to the contour of the other shape. However, this is not a limitation, and in other embodiments, the shapes of the first circuit board and the second circuit board may not be complementary but may be free shapes, respectively, thereby increasing the degree of freedom in designing the shapes of the first circuit board and the second circuit board. By way of example only, the free shape may be, for example, a regular shape, or an irregular shape. For example, where the first and second circuit boards are not complementary in shape, the first circuit board may be circular and the second circuit board may be rectangular.

According to some embodiments of the disclosure, the receptacle is formed at least in part by a resilient tab. In the embodiments, the binding post of the vibration type device can be directly inserted into the insertion hole formed by the elastic sheet, and the elastic sheet can provide proper elastic clamping force for the binding post.

According to some embodiments of the present disclosure, the first circuit board and the second circuit board may be in substantially the same plane. In such embodiments, this arrangement may significantly shorten the wire connection between the first circuit board and the second circuit board. Compared with the conventional lead connection mode of the compressor and the binding post, the length of the wire connection in the embodiments is much shorter, so that the interference of electromagnetic radiation of the wire is greatly reduced, and the structure is more compact.

According to some embodiments of the present disclosure, the first circuit board and the second circuit board may also have a drop so as not to be on the same plane. For example, the first circuit board may be located below or slightly below the second circuit board so that the first circuit board is closer to the top of a vibratory device such as a compressor. In such embodiments, this arrangement provides greater latitude with respect to the arrangement of the first and second circuit boards.

According to some embodiments of the present disclosure, an average gap distance between the first circuit board and the second circuit board may be in a range from 1mm to 1.5 mm. In these embodiments, the average gap distance in this range can provide the shortest length of wire connection between the first circuit board and the second circuit board, so that the arrangement between the first circuit board and the second circuit board is more compact and space-saving, and the vibration of the first circuit board is not transmitted to the second circuit board. However, this is not a limitation. In some other embodiments, the average gap distance may be larger, such as in the range of from 1mm to 2cm, or even in the range of from 1mm to 5cm, to provide greater redundancy.

According to some embodiments of the disclosure, the vibratory device is a compressor. In such embodiments, the modular circuit board may be applied directly to a compressor of a refrigeration system (such as an air conditioner).

According to some embodiments of the present disclosure, the control board is configured to be pluggable onto the driving board. In these embodiments, a simple connection between the control board and the circuit board is provided.

According to a third aspect of the present disclosure, a refrigeration device is provided. The refrigeration device comprises a compressor and a circuit box according to the second aspect. In the embodiments, the compressor and the circuit box may be applied in combination in the refrigeration system, thereby making it possible to provide a miniaturized refrigeration system.

According to some embodiments of the present disclosure, the refrigeration device further comprises a damping rubber ring disposed between the compressor and the circuit box. In the embodiments, the damping rubber ring can reduce or relieve the influence of the vibration of the compressor on the circuit box.

According to some embodiments of the disclosure, the refrigeration device is a portable refrigeration device. In such embodiments, the refrigeration device can be miniaturized, thereby enabling a portable refrigeration device to be provided.

Detailed Description

The principles of the present disclosure will now be described with reference to various exemplary embodiments shown in the drawings. It should be understood that these examples are described merely to enable those skilled in the art to better understand and further implement the present disclosure, and are not intended to limit the scope of the present disclosure in any way. It should be noted that where feasible, similar or identical reference numerals may be used in the figures and that similar or identical reference numerals may indicate similar or identical functions. One skilled in the art will readily recognize from the following description that alternative embodiments of the structures and methods illustrated herein may be employed without departing from the principles of the invention described herein.

As discussed in the background of the invention above, a conventional wiring method for a terminal of a compressor, such as a refrigeration system (e.g., air conditioner), is to electrically connect a drive plate to the terminal of the compressor via an electrical wire. However, the inventors have found that this connection method has problems in that: on one hand, the driving plate and the compressor cannot be compactly arranged, which is not beneficial to miniaturization; on the other hand, the wiring used to connect the drive plate to the terminals of the compressor is typically long, which results in a large electromagnetic interference signal generated by the radiation of the wiring. The conception of the present disclosure is: a circuit board (e.g., a driving board) is designed so that the circuit board can be directly mounted on a terminal post of a compressor, thereby shortening the use of electric wires and making the structure more compact and space-saving.

The connection manner of the terminal post of the compressor according to the present disclosure will be described below with reference to fig. 1 to 5. It should be noted that although the embodiments described below are described with a compressor as an example, it will be understood that the embodiments of the present disclosure are not limited to a compressor only, but may be applied to other vibration type devices having a terminal.

Fig. 1 shows an exploded schematic view of a connection relationship of a compressor and a circuit box according to one embodiment of the present disclosure.

As can be seen from fig. 1, from bottom to top, there are disposed a compressor 20, a cushion rubber 30, a lower case 41, a drive plate 10, a control plate 50, and an upper case 42, wherein the lower case 41 and the upper case 42 may constitute a case of a circuit box 40, and the drive plate 10 and the control plate 50 may be disposed within the circuit box 40.

The compressor 20 is typically a three-phase compressor, which is widely used in a refrigeration system such as an air conditioner. It will be appreciated, however, that other types of compressors 20 (e.g., single phase compressors) are possible in other embodiments. By way of example only, the exemplary three-phase compressor 20 has 3 terminals for connecting three-phase power so that sufficient drive power can be provided.

The cushion rubber 30 is disposed between the compressor 20 and the circuit box 40, and functions to alleviate or reduce the influence of vibration of the compressor 20 during operation on the circuit board in the circuit box 40. In particular, the damping rubber ring 30 may be provided to alleviate or mitigate the influence of vibration of the compressor 20 during operation on the drive plate 10 in the circuit box 40.

In some embodiments, the cushion rubber ring 30 is provided with a hole 31 matching with the terminal post 21 of the compressor 20. By way of example only, 3 studs 21 of the compressor 20 and corresponding 3 holes of the cushion rubber 30 are shown in fig. 1. When assembled, the terminal posts 21 of the compressor 20 may pass through the corresponding holes 31 of the cushion rubber 30, and then the cushion rubber 30 may be closely attached to the top of the compressor 20. In some embodiments, the cushion rubber 30 may also be provided with one or more protrusions 33 that function to abut against a lower surface of a first circuit board 11 (discussed further below) in the drive board 10, thereby providing a stop for the first circuit board 11 while also acting as a cushion for the first circuit board 11. In some embodiments, one or more protrusions 33 may be disposed at the top center of the cushion rubber 30, thereby providing a simple resilient cushion and stop. In some other embodiments, one or more protrusions 33 may be evenly distributed on the top of the cushion rubber 30 to provide a more uniform resilient cushioning and stop.

The circuit box 40 may include an upper case 42 and a lower case 41. The circuit box 40 functions to protect the driving board 10 and the control board 50 installed in the circuit box 40.

The bottom of the lower case 41 is provided with a hole 411. The hole 411 may be sized to correspond to the outer diameter of the cushion rubber 30, thereby allowing at least a majority of the cushion rubber 30 and the terminal post 21 of the compressor 20 to pass through the hole 411 and then be inserted into the receptacle 112 (discussed further below) of the first circuit board 11 of the drive plate 10, thereby electrically connecting the compressor 20 to the first circuit board 11.

The bottom of the lower case 41 may also mechanically support the second circuit board 12 of the driving board 10 (to be discussed further later), thereby achieving rigid support and protection of the second circuit board 12 by the lower case 41. The control board 50 may be removably mounted on the second circuit board 12. In order to securely locate the drive board 10 and control board 50 in the circuit box 40, in some embodiments, the upper housing 42, control board 50, drive board 10, and lower housing 41 may be locked together via screws. In some embodiments, the upper housing 42 and the lower housing 41 may also snap together.

The drive plate 10 functions to drive the operation of the compressor 20. In the case of power from a dc power source (not shown), the drive board 10 may include an inverter circuit to convert dc power to ac power, such as three-phase power. As an example, the dc power supply may be, for example, a portable battery such as a lithium battery. It will be appreciated that it is advantageous to supply the compressor via the drive plate 10 with a dc power source (a battery such as a lithium battery) as the power supply source, since this will improve the portability of the overall cooling system, making it possible to provide a portable and miniaturised refrigeration system. However, this is not a limitation. It will also be appreciated that in other embodiments, drive plate 10 may also be designed to be driven by alternating current from the mains.

The first circuit board 11 of the driving board 10 is provided with an insertion hole 112. The terminal post 21 of the compressor 20 can be directly inserted into the insertion hole 112 of the first circuit board 11, which makes the wiring structure of the compressor 20 concise and compact, thereby contributing to miniaturization of the refrigeration system. In order to more clearly see the connection of the first circuit board 11 and the terminal posts 21 of the compressor 20, fig. 2 shows a side view schematically illustrating the connection relationship of the compressor and the driving plate according to one embodiment of the present disclosure.

Referring back to fig. 1, a control board 50 is disposed above the drive board 10. The control plate 50 functions to control the operation of the compressor 20. A user may send various control commands to the control panel 50 via a user interface (not shown) to control the starting, pausing, stopping of the compressor and various operating parameters of the compressor 20.

In some embodiments, the drive board 10 and the control board 50 may be separate circuit boards. Such a separate circuit board may allow more freedom in the design of the driving board 10 and the control board 50, so that the size and structure of the driving board 10 and the control board 50 may be individually designed depending on the allowable space. On the other hand, the independent circuit board can also make the maintenance of circuit board more convenient.

In some embodiments, the control board 50 may be disposed above the drive board 10. The control board 50 may be connected to the driver board 10 in a pluggable manner, which makes the mounting and communication connection of the control board 50 and the driver board 10 simple, thereby providing a compact mounting arrangement of both the control board 50 and the driver board 10.

In other embodiments, the drive board 10 and the control board 50 may also be integrated on a single circuit board, which may reduce the number of components within the circuit box 40, thereby helping to provide a more compact mounting arrangement.

In the assembly process of the compressor 20 and the circuit box 40 of the embodiment of fig. 1, the three terminals 21 of the compressor 20 are first inserted through the three holes 31 of the cushion rubber 30, then through the holes 411 of the lower housing 41 of the circuit box 40, and then inserted into the corresponding three insertion holes 112 on the first circuit board 11 in the drive plate 10, thereby achieving the electrical connection of the terminals 21 of the compressor 20 and the first circuit board 11 of the drive plate 10. Next, the control board 50 may be insertably mounted on the driving board 10, and finally the upper case 42 of the circuit box 40 is mounted, thereby achieving the assembly connection of the compressor 20 and the circuit box 40.

It is well known that compressors will operate at high frequencies during operation and produce small amplitude circumferential vibrations. It will be appreciated that it is disadvantageous to rigidly connect a drive plate directly to the terminals of the compressor, as this can result in the drive plate being subjected to vibration over time, thereby affecting the useful life of important parts of the drive plate. To this end, the inventor of the present disclosure proposes a combined circuit board. The combined circuit board can prevent the impact of the vibration of the compressor on important parts on the circuit board and provide compact connection between the compressor and the driving plate.

Embodiments of the modular circuit board of the present disclosure will be described below with further reference to fig. 3 and 4.

FIG. 3 illustrates a perspective view of a drive plate mounted on a compressor according to one embodiment of the present disclosure; and fig. 4 shows a schematic top view of a drive plate according to one embodiment of the present disclosure.

As shown in fig. 3 and 4, the driving board 10 is a combined type circuit board, which can be divided into a first circuit board 11 and a second circuit board 12. The first circuit board 11 and the second circuit board 12 are connected via a flexible conductive member 13.

In some embodiments, the first circuit board 11 and the second circuit board 12 are each rigid circuit boards, such as rigid PCB circuit boards, so that rigid support may be provided directly for the circuit components thereon. In some embodiments, the shapes of the first circuit board 11 and the second circuit board 12 may be complementary, so that the first circuit board 11 and the second circuit board 12 may be conveniently cut from the same integrated circuit board. This way of cutting makes the manufacture of the first circuit board 11 and the second circuit board 12 simpler.

In some embodiments, the first circuit board 11 and the second circuit board 12 may be in substantially the same plane. This arrangement is particularly advantageous in that the length of wiring used between the first circuit board 11 and the second circuit board 12 is much shorter than in the prior art in which the drive plate is directly wired to the terminals of the compressor. This means that no long wires are needed between the first circuit board 11 and the second circuit board 12 to achieve electrical connection therebetween, which can greatly reduce the electromagnetic interference caused by the length of the wires and improve the stability of signal transmission of the whole system; on the other hand, the connection between the first circuit board 11 and the terminals of the compressor 20 can be made more compact.

In some embodiments, the average gap distance between the first circuit board 11 and the second circuit board 12 may be maintained in a range from 1mm to 1.5 mm. The distance length is set so that the electrical connection between the first circuit board 11 and the second circuit board 12 can be ensured, and simultaneously, the vibration of the second circuit board 11 can be ensured not to directly touch the second circuit board 12.

The first circuit board 11 is provided with a jack 112, and the jack 112 is used for directly inserting the terminal 21 of the compressor 20 into the jack 112, so that the first circuit board 11 and the terminal 21 of the compressor 20 are electrically connected. In some embodiments, the insertion hole 112 is formed, for example, at least partially by the spring piece 111, so that the spring piece 111 can elastically hold the stud 21 in a state where the stud 21 is directly inserted into the insertion hole 112. In some embodiments, the elastic sheet 111 may be soldered on the first circuit board 11, so as to achieve a fixed connection of the elastic sheet 111 on the first circuit board 11.

In some embodiments, only the sockets 112, solder joints, conductive traces, and other high-shock-resistance circuit components may be disposed on the first circuit board 11, which may provide the first circuit board 11 with high shock resistance. However, this is not a limitation, and in embodiments that do not need to be applied to a vibration scenario, the first circuit board 11 may also be provided with other circuit components that are weak against vibrations.

The second circuit board 12 is connected to the first circuit board 12 via the flexible conductive member 13. The second circuit board 12 is used for carrying some driving components (e.g., driving circuits) with weak shock resistance on the driving board, so that the driving components are protected from the shock, and the service life of the driving components is prolonged. Again, this is not limiting. In some embodiments, the second circuit board 12 may also carry circuit components that are resistant to shock.

The function of the flexible conductive member 13 is to flexibly and electrically connect the first circuit board 11 and the second circuit board 12, which is to prevent the vibration of the first circuit board 11 from being transmitted to the second circuit board 12 via the conductive member 13 so as not to affect important circuit components (e.g., driving circuits) on the second circuit board 12. As an example, the flexible conductive member 13 may be simply implemented as a U-shaped flexible electric wire that can withstand a long-term shock of the first circuit board 11 while always maintaining the electrical connection between the first circuit board 11 and the second circuit board 12 without being disconnected. However, it will be appreciated that in other embodiments, the flexible conductive member 13 may also take other forms capable of maintaining a flexible electrical connection, such as a flexible sheet, a flexible ring.

Fig. 5 is a schematic view showing an overall structure of a connection relationship of a compressor and a circuit box according to an embodiment of the present disclosure. In fig. 5, the driving plate 10 (i.e., the combined circuit board) composed of the first circuit board 11 and the second circuit board 12 described above, and the control plate 50 are installed in the circuit box 40, and the circuit box 40 may be installed on the compressor 20 via the damper rubber 30.

The embodiments of the connection of the compressor 20 and the circuit box 40 (particularly, with the first circuit board 11 in the circuit box 40) of the present disclosure have been described above in detail. It will be appreciated that the modular circuit board concept of the present disclosure makes it possible to mount the terminal posts 21 of the compressor 20 directly on the drive plate 10, and the connection between the compressor 20 and the drive plate 10 can be greatly simplified, making the connection between the compressor 20 and the drive plate 10 more compact and saving space. Furthermore, with a very short wire connection between the first circuit board 11 and the second circuit board 12 in the combined circuit board 10, electromagnetic interference caused by the length of the wire can be greatly reduced.

In addition, when the compressor 20 is in an operating state, the vibration generated by the operation of the compressor 20 can be transmitted only to the first circuit board 11 via the terminal posts 21 of the compressor 20, and not to the second circuit board 12 via the flexible conductive member 13, thereby protecting important circuit components on the second circuit board 12. Meanwhile, the shock absorbing rubber ring 30 can further relieve the shock pressure of the first circuit board 11.

Various embodiments of the present disclosure are described above primarily with reference to a compressor and a drive plate as examples, but it will be understood that the present disclosure is not limited to the above-described compressor and drive plate, but may be applied to other possible application scenarios. For example, in other application scenarios, the compressor may be other vibratory devices and the drive plate may be other circuit boards.
