Description

Technical Field

[0001] The present invention relates to the technical field of air conditioning, and in particular to a metering module fixing device and an air conditioner. Background Art

[0002] At present, in order to detect the real-time power consumption parameters of the air conditioner, a metering module is usually added to the air conditioner. However, the existing metering module is often directly installed on the outside of the air conditioner, which not only affects the appearance of the air conditioner, but also the metering module carries strong electricity, posing safety hazards such as electric shock and fire. Summary of the invention

[0003] The problem solved by the invention is how to eliminate the potential safety hazards such as electric shock and fire caused by the existing metering module.

[0004] In order to solve the above problems, the present invention provides a metering module fixing device, comprising:

[0005] An upper housing, on which a first connecting piece for connecting with the electric control box cover is provided;

[0006] and a lower housing, on which a second connecting member is provided, and the lower housing is fixed in the electric control box through the second connecting member;

[0007] A cavity for accommodating a metering module is formed between the upper shell and the lower shell, and the upper shell is detachably connected to the lower shell.

[0008] Compared with the prior art, the metering module fixing device of the present invention installs the metering module, such as an electric meter, into the electrical control box of the air conditioner. This not only beautifies the appearance of the air conditioner, but also eliminates the safety hazards such as electric shock and fire caused by installing the metering module outside the air conditioner, thereby improving the practicality of the air conditioner and its safety during use.

[0009] Optionally, the first connecting member is in an elastic cantilever structure and is arranged opposite to each other at two ends of the upper shell.

[0010] In this way, after the upper shell and the lower shell are assembled and installed, the entire metering module fixing device is fixed in the electric control box, and the electric control box cover is closed. At this time, the electric control box cover exerts a pressing force on the first connecting piece on the upper shell, so that abutment is formed between the first connecting piece and the electric control box cover, thereby fixing the upper shell between the lower shell and the electric control box cover. This not only limits the upward movement of the metering module fixing device, effectively ensures the firmness and stability of the metering module fixing device installed in the electric control box, but also makes the operation simple and convenient.

[0011] Optionally, the first connecting member includes a pressing portion and a supporting portion, the supporting portion is a V-shaped structure, the connecting end of the V-shaped structure is connected to the upper shell, the opening end of the V-shaped structure is connected to the pressing portion, and the pressing portion is arranged parallel to the side of the upper shell facing away from the lower shell.

[0012] In this way, compared with a single cantilever structure, the V-shaped supporting portion of the first connecting member not only increases the supporting points and reduces the pressing force exerted on the single cantilever, so that the first connecting member can better support the electric control box cover; it also enhances the structural strength of the first connecting member, which can prevent the first connecting member from breaking during the pressing process; in addition, the pressing portion is arranged parallel to the inner surface of the electric control box cover, so that the pressing portion can be completely fitted with the electric control box cover, thereby increasing the abutment area between the first connecting member and the electric control box cover, and making the connection between the first connecting member and the electric control box cover tighter and firmer; at the same time, the pressing portions of the first connecting member are distributed at the four vertices of the rectangle, so that the force on the first connecting member is more balanced, further improving the stability of the abutment between the first connecting member and the electric control box cover.

[0013] Optionally, the vertical distance between the side of the pressing portion facing the electric control box cover and the side of the upper shell facing the electric control box cover is a first distance, and when the electric control box cover is pressed on the upper shell, the vertical distance between the side of the electric control box cover facing the upper shell and the side of the upper shell facing the electric control box cover is a second distance, and the difference between the first distance and the second distance ranges from 2 mm to 4 mm.

[0014] In this way, it can be ensured that when the electric control box cover is covered on the electric control box, the electric control box cover can exert a certain pressing force on the first connecting member, thereby limiting the upward movement of the upper shell body, and further improving the tightness and firmness of the abutment between the electric control box cover and the upper shell body.

[0015] Optionally, the second connecting member is in the form of a block structure and is disposed on a side of the lower shell away from the upper shell, and the block structure is used for plugging and mating with a terminal board in the electric control box.

[0016] In this way, the fixed connection between the metering module fixing device and the terminal board can be achieved by plugging the second connecting member into the terminal board, which has a simple structure and is easy to install.

[0017] Optionally, a slot is provided on the terminal board, the second connecting member is plugged into the slot, and the second connecting member is provided with a guide surface for guiding the second connecting member to be inserted into the slot.

[0018] In this way, the guide surface is provided to guide the second connecting member to be inserted into the slot, thereby improving the assembly efficiency of the metering module fixing device.

[0019] Optionally, when the second connecting member is plugged into the slot, a distance between the guide surface and a slot wall of the slot is less than or equal to 0.1 mm.

[0020] In this way, setting the distance between the guide surface and the groove wall of the slot between 0 and 0.1 mm can prevent the second connecting member from being loosely connected to the terminal board when the distance between the guide surface and the groove wall of the slot is too large, thereby further ensuring the stability of the connection between the metering module fixing device and the terminal board.

[0021] Optionally, at least one reinforcing rib is further provided on the second connecting member.

[0022] In this way, the provision of the reinforcing ribs can not only enhance the structural strength of the second connecting member, but also reduce the contact area between the second connecting member and the slot wall of the slot, thereby reducing the friction resistance when the second connecting member is inserted, and facilitating the plug-in installation between the metering module fixing device and the terminal board.

[0023] Optionally, a groove is provided on a side of the lower shell facing away from the upper shell, the second connecting member is arranged in the groove, and the cross-sectional area of ​​the groove is larger than the cross-sectional area of ​​the terminal board.

[0024] In this way, when the lower shell is plugged into the terminal board through the second connecting piece, since the cross-sectional area of ​​the groove is larger than the cross-sectional area of ​​the terminal board, the lower shell can cover the entire terminal board, thereby increasing the contact area between the terminal board and the lower end surface of the lower shell, so that the metering module fixing device can be more stably fixed on the terminal board. At the same time, the supporting force provided by the terminal board to the lower shell is also increased.

[0025] Optionally, a screw column is provided on the upper shell, and a countersunk hole is provided at a position on the lower shell corresponding to the screw column, and the upper shell and the lower shell are fixedly connected at the screw column and the countersunk hole by fasteners.

[0026] In this way, by screwing the fasteners into the countersunk holes and screw columns in sequence, a fixed connection between the upper shell and the lower shell can be achieved, and the connection is firm; at the same time, the setting of the countersunk holes can accommodate the large end of the fasteners in the countersunk part of the countersunk holes, preventing safety hazards such as scratches on operators caused by the fasteners protruding from the lower end surface of the lower shell, thereby improving the safety of the metering module fixing device during use or assembly.

[0027] Optionally, a fixing member for fixing the metering module is provided on a side of the lower shell facing the upper shell, and the fixing member is located in the cavity.

[0028] In this way, by providing a fixing piece to further fix the metering module, it is possible to prevent the metering module from shaking in the cavity when moving or being subjected to vibration shock, thereby preventing the metering module from being damaged, thereby ensuring the normal use of the metering module.

[0029] Optionally, a wire passing hole is further provided on the lower shell, and the wire passing hole is communicated with the cavity.

[0030] In this way, the wiring harness connected to the metering module can pass through the housing through the wire hole so as to be electrically connected to other components of the air conditioner.

[0031] To solve the above problems, the present invention also provides an air conditioner, including an electric control box assembly and the above-mentioned metering module fixing device, the electric control box assembly includes an electric control box cover and an electric control box, and the metering module fixing device is arranged in the electric control box.

[0032] The advantages of the air conditioner and the above-mentioned metering module fixing device over the prior art are the same, which will not be described in detail here. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0047] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0048] In the description of the present invention, it should be noted that a coordinate system XYZ is provided herein, wherein the positive direction of the X axis represents the right direction, the reverse direction of the X axis represents the left direction, the positive direction of the Y axis represents the front direction, the reverse direction of the Y axis represents the rear direction, the positive direction of the Z axis represents the top, and the reverse direction of the Z axis represents the bottom. The directions or positional relationships indicated by the terms "upper", "lower", "left", "right", "high", "low", etc. are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention.

[0049] Combination Figures 1 to 4 As shown, this embodiment provides a metering module fixing device, including an upper shell 1 and a lower shell 2, the upper shell 1 is provided with a first connecting member 12 for connecting with the electric control box cover 5; the lower shell 2 is provided with a second connecting member 21, and the lower shell 2 is fixed in the electric control box 6 by the second connecting member 21; a cavity 3 for accommodating the metering module 4 is formed between the upper shell 1 and the lower shell 2, and the upper shell 1 and the lower shell 2 are detachably connected.

[0050] The upper shell 1 and the lower shell 2 are both hollow structures. When the upper shell 1 and the lower shell 2 are buckled together, the hollow structures of the two are combined into a cavity 3 for placing the metering module 4. The first connecting member 12 is located above the upper shell 1 (i.e. Figure 1The second connecting member 21 is located below the lower shell 2. After the upper shell 1 and the lower shell 2 are assembled and installed, the upper shell 1 is located above the lower shell 2. It should be noted that the orientations mentioned here and below are based on the orientations indicated by the XYZ coordinate system in the figure. In actual production, due to different types or models of air conditioners, the installation status of the metering module fixing device in the electric control box is also different. For example, in one air conditioner, the upper shell 1 is located above the lower shell 2, and in another air conditioner, the upper shell 1 is located below the lower shell 2. For another example, in one air conditioner, the upper shell 1 is located in front of the lower shell 2, and in another air conditioner, the upper shell 1 is located behind the lower shell 2. The upper shell 1 is connected to the electric control box cover 5 through the first connecting member 12, that is, the electric control box cover 5 limits the freedom of the upper shell 1 in the upward direction, and the lower shell 2 is fixedly connected to the electric control box 5 through the second connecting member 21, that is, the electric control box 6 limits the freedom of the lower shell 2 in the downward direction, so that the metering module fixing device is fixed between the electric control box cover 5 and the electric control box 6.

[0051] Compared with the prior art, the metering module fixing device in this embodiment installs the metering module 4, such as an electric meter, into the electrical control box of the air conditioner. This not only beautifies the appearance of the air conditioner, but also eliminates the safety hazards such as electric shock and fire caused by the metering module 4 being installed outside the air conditioner, thereby improving the practicality of the air conditioner and its safety during use.

[0052] Optionally, combined Figure 4 and Figure 6 As shown, the first connecting member 12 is in an elastic cantilever structure and is disposed opposite to each other at two ends of the upper shell 1 .

[0053] That is to say, two first connecting members 12 are provided on the upper shell 1, and the two first connecting members 12 are respectively located at the two ends of the upper shell 1. In this embodiment, the first connecting members 12 are located at the left and right ends of the upper shell 1 as an example for explanation, wherein the left and right ends of the upper shell 1 refer to the upper shell 1 at Figure 1 The two ends in the X-axis direction of the middle shell 1, and the first connecting member 12 is arranged at both ends of the upper shell 1 opposite to each other, which means that the first connecting member 12 at the left end of the upper shell 1 and the first connecting member 12 at the right end of the upper shell 1 are arranged at the same position. Figure 6 The orthographic projections on the ZY plane coincide. One end of the first connecting member 12 is fixedly connected to the upper housing 1, and the other end is located above the upper housing 1 and is not connected to the upper housing 1, forming a free end, and the first connecting member 12 is elastic, so as to form an elastic cantilever structure, that is, the lower end of the first connecting member 12 is connected to the upper housing 1, and the upper end of the first connecting member 12 is not connected to other parts when the upper housing 1 is separated from the electric control box cover 5, and is in a free state; the elastic cantilever structure is pressed by the electric control box cover 5 to fix the upper housing 1 between the lower housing 2 and the electric control box cover 5.

[0054] In this embodiment, after the upper shell 1 and the lower shell 2 are assembled and installed, the entire metering module fixing device is fixed in the electric control box 6, and the electric control box cover 5 is covered. At this time, the electric control box cover 5 exerts a pressing force on the first connecting member 12 on the upper shell 1, so that abutment is formed between the first connecting member 12 and the electric control box cover 5, thereby fixing the upper shell 1 between the lower shell 2 and the electric control box cover 5, which not only limits the upward movement of the metering module fixing device, effectively ensures the firmness and stability of the metering module fixing device installed in the electric control box 6, but also is simple and convenient to operate.

[0055] Optionally, combined Figure 6 and Figure 7 As shown, the first connecting member 12 includes a pressing portion 121 and a supporting portion 122, the supporting portion 122 is a V-shaped structure, the connecting end of the V-shaped structure is connected to the upper shell 1, the opening end of the V-shaped structure is connected to the pressing portion 122, and the pressing portion 121 is arranged parallel to the side of the upper shell 1 facing away from the lower shell 2.

[0056] The support portion 122 includes two cantilevers, one end of the two cantilevers intersects, and the other end extends away from the upper shell 1 and is respectively connected to the pressing portion 121 to form a V-shaped structure of the support portion 122. It should be noted that the V-shaped structure mentioned here includes structures of similar shapes such as V-shape or U-shape. This embodiment takes the support portion 122 in a V-shape as an example. At this time, an angle is formed between the two cantilevers of the support portion 122, wherein the end where the two cantilevers intersect is the connecting end of the V-shaped structure, and the end where the two cantilevers are separated is the opening end of the V-shaped structure, and the pressing portion 121 is parallel to the side surface of the upper shell 1 facing away from the lower shell 2, which is equivalent to the pressing portion 121 being parallel to the inner surface of the electric control box cover 5, wherein the side surface of the upper shell 1 facing away from the lower shell 2 refers to the upper end surface of the upper shell 1, that is, Figure 6 The end surface of the middle upper shell 1 is located in the positive direction of the Z axis. The inner surface of the electric control box cover 5 refers to the side of the electric control box cover 5 facing the upper shell 1. Conversely, the side of the electric control box cover 5 facing away from the upper shell 1 is the outer surface of the electric control box cover 5.

[0057] In this embodiment, compared with a single cantilever structure, the V-shaped supporting portion 122 of the first connecting member 12 not only increases the supporting points and reduces the pressing force on the single cantilever, so that the first connecting member 12 can better support the electric control box cover 5; it also enhances the structural strength of the first connecting member 12, which can prevent the first connecting member 12 from breaking during the pressing process; in addition, the pressing portion 121 is arranged parallel to the inner surface of the electric control box cover 5, so that the pressing portion 121 can be completely fitted with the electric control box cover 5, thereby increasing the abutment area between the first connecting member 12 and the electric control box cover 5, and making the connection between the first connecting member 12 and the electric control box cover 5 tighter and firmer; at the same time, the pressing portions 121 of the first connecting member 12 are distributed at the four vertices of the rectangle, so that the force on the first connecting member 12 is more balanced, further improving the stability of the abutment between the first connecting member 12 and the electric control box cover 5.

[0058] Optionally, the vertical distance between the side of the pressing portion 121 facing the electric control box cover 5 and the side of the upper shell 1 facing the electric control box cover 5 is a first distance, and when the electric control box cover 5 is pressed on the upper shell 1, the vertical distance between the side of the electric control box cover 5 facing the upper shell 1 and the side of the upper shell 1 facing the electric control box cover 5 is a second distance, and the difference between the first distance and the second distance ranges from 2 mm to 4 mm.

[0059] Combination Fig.11 and Fig.12 As shown, the side of the pressing portion 121 facing the electric control box cover 5 is the upper end surface of the pressing portion 121, the side of the upper shell 1 facing the electric control box cover 5 is the upper end surface of the upper shell 1, and the vertical distance a between the upper end surface of the pressing portion 121 and the upper end surface of the upper shell 1 is the first distance. Fig.11 When the electric control box cover 5 is pressed on the upper housing 1, the vertical distance b between the side of the electric control box cover 5 facing the upper housing 1 and the side of the upper housing 1 facing the electric control box cover 5 is the second distance, as shown in FIG. Fig.12 That is, there is an interference of 2mm to 4mm between the first connecting member 12 and the electric control box cover 5 during assembly, that is, when the electric control box cover 5 is installed on the electric control box 6, a pressing force is applied to the pressing portion 121, so that the pressing portion 121 is pushed downward (i.e., toward Fig.11 The negative direction of the Z axis moves 2 to 4 mm.

[0060] In this embodiment, it can be ensured that when the electric control box cover 5 is covered on the electric control box 6, the electric control box cover 5 can apply a certain pressing force to the first connecting member 12, thereby limiting the upward movement of the upper shell 1, and further improving the tightness and firmness of the contact between the electric control box cover 5 and the upper shell 1.

[0061] Optionally, combined Figure 3 and Figure 5As shown, the second connecting member 21 is in the form of a stopper structure and is disposed on a side of the lower housing 2 facing away from the upper housing 1 . The stopper structure is used for plugging and mating with the terminal board 61 in the electric control box 6 .

[0062] Specifically, the block structure is in a block or columnar structure; the upper end of the lower shell 2 faces the upper shell 1, and the lower end of the lower shell 2 faces away from the upper shell 1. The side of the lower shell 2 facing away from the upper shell 1 is the lower end of the lower shell 2, that is, the second connecting member 21 is arranged at the lower end of the lower shell 2. When the metering module fixing device is installed in the electric control box 6, the metering module fixing device is usually fixed on the terminal board 61 in the electric control box 6. In this way, the fixed connection between the metering module fixing device and the terminal board 61 can be realized by plugging the second connecting member 21 and the terminal board 61, which has a simple structure and is easy to install.

[0063] Optionally, combined Figure 3 , Fig. 9 and Fig.10 As shown, a slot 611 is provided on the terminal board 61 , the second connector 21 is plugged into the slot 611 , and a guide surface 211 is provided on the second connector 21 for guiding the second connector 12 to be inserted into the slot 611 .

[0064] The slot 611 may be a polygonal slot, a circular slot, or a U-shaped slot or other geometrical slots, which are not specifically limited in this embodiment. When the slot 611 is a polygonal slot, the slot 611 has a plurality of slot walls, and the guide surface 211 on the second connector 21 is an inclined structure, and the second connector 21 may be provided with a plurality of guide surfaces 211; when the slot 611 is a circular slot, the slot 611 has a slot wall, and the guide surface 211 on the second connector 21 is an arc structure. However, regardless of the shape of the slot 611, the distance between the guide surface 211 and the slot wall of the slot 611 increases along the direction in which the second connector 21 is inserted into the slot 611, that is, the cross-sectional area of ​​one end of the second connector 21 inserted into the slot 611 gradually decreases along the insertion direction of the second connector 21.

[0065] In this embodiment, the guide surface 211 is provided to guide the second connecting member 21 to be inserted into the slot 611 , thereby improving the assembly efficiency of the metering module fixing device.

[0066] Optionally, when the second connecting member 21 is plugged into the slot 611 , the distance between the guide surface 211 and the slot wall of the slot 611 is less than or equal to 0.1 mm.

[0067] When the slot 611 is a polygonal slot, the slot 611 has a plurality of planar slot walls. In order to achieve the guiding effect, the guide surface 211 on the second connector 21 is an inclined structure. At this time, the spacing between the guide surface 211 and the slot wall of the slot 611 refers to the distance between the slot wall corresponding to the guide surface 211 and the guide surface 211 among the plurality of slot walls of the slot 611; when the slot 611 is a circular slot, the slot 611 has an arcuate slot wall. In order to achieve the guiding effect, the guide surface 211 on the second connector 21 is an arcuate structure. At this time, the spacing between the guide surface 211 and the slot wall of the slot 611 refers to the distance between the arcuate slot wall of the slot 611 and the arcuate guide surface 211. In other words, there is a gap between the guide surface 211 and the slot wall of the slot 611, and the gap is less than or equal to 0.1 mm. If the spacing between the guide surface 211 and the slot wall of the slot 611 is set too large, the plug-in between the second connector 21 and the terminal board 61 is not firm, so that the metering module fixing device is easy to shake.

[0068] In this embodiment, the distance between the guide surface 211 and the groove wall of the slot 611 is set between 0 and 0.1 mm, which can prevent the second connecting member 21 from being loosely connected to the terminal board 61 when the distance between the guide surface 211 and the groove wall of the slot 611 is too large, thereby further ensuring the stability of the connection between the metering module fixing device and the terminal board 61.

[0069] Optionally, combined Fig. 9 and Fig.10 As shown, at least one reinforcing rib 212 is further provided on the second connecting member 21 .

[0070] A portion of the second connecting member 21 is provided with a guide surface 211 , while another portion is not provided with the guide surface 211 . The reinforcing rib 212 is located on the portion of the second connecting member 21 where the guide surface 211 is not provided.

[0071] In this embodiment, the provision of the reinforcing rib 212 can not only enhance the structural strength of the second connecting member 21, but also reduce the contact area between the second connecting member 21 and the slot wall of the slot 611, thereby reducing the friction resistance when the second connecting member 21 is inserted, and facilitating the plug-in installation between the metering module fixing device and the terminal board 61.

[0072] Optionally, combined Figure 1 , Figure 3 and Figure 5 As shown, a groove 22 is provided on the side of the lower housing 2 facing away from the upper housing 1 , the second connecting member 2 is arranged in the groove 22 , and the cross-sectional area of ​​the groove 22 is larger than the cross-sectional area of ​​the terminal board 61 .

[0073] The side of the lower shell 2 facing away from the upper shell 1 is the lower end of the lower shell 2, that is, the groove 22 is arranged at the lower end of the lower shell 2, and the groove 22 is concave from bottom to top; the cross section of the groove 22 refers to the cross section of the groove 22 perpendicular to the Figure 3 The cross section of the terminal board 61 refers to the cross section of the terminal board 61 perpendicular to the Z axis. Figure 3 In this embodiment, the cross-sectional area of ​​the groove 22 is greater than the cross-sectional area of ​​the terminal plate 61, that is, the groove 22 is perpendicular to the Figure 3 The orthographic projection on the plane of the Z axis covers the terminal board 61 at right angles to Figure 3 Orthographic projection on the plane with the Z axis in between.

[0074] In this embodiment, when the lower shell 2 is plugged into the terminal board 61 through the second connecting member 21, since the cross-sectional area of ​​the groove 22 is larger than the cross-sectional area of ​​the terminal board 61, the lower shell 2 can cover the entire terminal board 61, thereby increasing the contact area between the terminal board 61 and the lower end surface of the lower shell 2, so that the metering module fixing device can be more stably fixed on the terminal board 61. At the same time, the supporting force provided by the terminal board 61 to the lower shell 2 is also increased.

[0075] Optionally, combined Figure 2 and Figure 6 As shown, a screw column 11 is provided on the upper shell 1, and a countersunk hole 23 is provided on the lower shell 2 at a position corresponding to the screw column 11. The upper shell 1 and the lower shell 2 are fixedly connected at the screw column 11 and the countersunk hole 23 by fasteners.

[0076] The screw column 11 is arranged on the side of the upper shell 1 facing the lower shell 2, that is, the screw column 11 is arranged at the lower end of the upper shell 1. In order to prevent relative rotation between the upper shell 1 and the lower shell 2, at least two screw columns 11 are usually arranged, and these two screw columns 11 are respectively located at the left and right ends of the upper shell 1. Correspondingly, the countersunk hole 23 is arranged at the left and right ends of the lower shell 2 at positions corresponding to the screw column 11, and the screw hole 11 and the countersunk hole 23 are coaxially arranged.

[0077] In this embodiment, the upper shell 1 and the lower shell 2 can be fixedly connected by screwing the fasteners into the countersunk holes 23 and the screw columns 11 in sequence, and the connection is firm; at the same time, the setting of the countersunk holes 23 can accommodate the large end of the fastener in the countersunk part of the countersunk holes 23, thereby preventing safety hazards such as scratches on the operator caused by the fasteners protruding from the lower end surface of the lower shell 2, thereby improving the safety of the metering module fixing device during use or assembly.

[0078] Optionally, combined Figure 8As shown, a fixing member 24 for fixing the metering module 4 is provided on a side of the lower housing 2 facing the upper housing 1 , and the fixing member 24 is located in the cavity 3 .
