[0038] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and in no way restrictive of the present application and its application or use. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.
[0039] In the description of the present application, it should be understood that the orientation or positional relationships indicated by orientation words such as "front, back, up, down, left, right", "horizontal, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the orientation or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present application and simplifying the description. Without contrary explanations, these orientation words do not indicate and imply that the devices or elements referred to must have specific orientations or be constructed and operated in specific orientations. Therefore, they should not be construed as limiting the protection scope of the present application; the orientation words "inside, outside" refer to the inside and outside relative to the contours of the respective components.
[0040] For ease of description, spatial relative terms, such as "above", "over", "on the upper surface", "upper", etc., may be used herein to describe the spatial positional relationship of one device or feature to other devices or features as shown in the figures. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is inverted, a device described as "above" or "over" other devices or structures will then be positioned "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both the orientation of "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the corresponding explanations for the spatial relative descriptions used herein will be made accordingly.
[0041] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. Without additional statements, the above terms have no special meanings, and thus should not be construed as limiting the protection scope of the present application.
[0042] Referring jointly to Figures 1 to 6 As shown, according to an embodiment of the present application, a display component includes:
[0043] A keypad 2 and a display board 4, which are spaced face to face;
[0044] A shrapnel connection unit, which is provided between the keypad 2 and the display board 4 to electrically connect the keypad 2 and the display board 4;
[0045] The shrapnel connection unit includes an elastic member and a contact 21 that are in mutual abutment, and the elastic member and the contact 21 are respectively provided on the opposite side surfaces of the keypad 2 and the display board 4.
[0046] In the present application, the keypad 2 and the display board 4 are in abutting electrical connection through the shrapnel connection unit, completely avoiding the problems of skew and detachment of traditional pin headers and the problem of perforation of the female socket. In this way, the problem of floating height of the female socket after soldering is also avoided. Therefore, the reliability of the connection of the remote controller and the stability of the button touch function are improved.
[0047] The present application uses the shrapnel connection unit to electrically connect the keypad 2 and the display board 4 through a contact electrical connection method, eliminating the traditional connection method of male and female connectors. Based on the fact that the elastic member and the contact 21 in the shrapnel connection unit are in an abutting contact manner, the problem of floating height of the female socket will not occur. Even if there is a partial floating height phenomenon, since the elastic member is elastically abutted on the contact 21, the problem of poor contact affecting the button touch function of the remote controller will not occur.
[0048] For the setting of the elastic member and the contact 21, they can be respectively arranged on the opposite sides of the display board 4 and the key board 2. That is, the elastic member can be arranged on one of the display board 4 and the key board 2, and the contact 21 is arranged on the other. During assembly, it is only necessary to make the elastic member abut against the contact 21 to ensure electrical connection.
[0049] The above-mentioned electrical connection refers to the connection of the circuit. That is, after the elastic member and the contact 21 are abutted, the current is in a flowing state between the two.
[0050] In some embodiments,
[0051] The elastic member includes a spring piece 52 and a spring pad 53. The first end of the spring piece 52 abuts against the contact 21, and the second end is fixedly connected to the spring pad 53, and is connected to the key board 2 or the display board 4 through the spring pad 53.
[0052] In the structural setting of the elastic member, the present application adopts the structure of the spring piece 52 and the spring pad 53. One end of the spring piece 52 can elastically abut against the contact 21 to ensure the stability and reliability of the electrical connection. The other end is fixedly connected to the key board 2 or the display board 4 by soldering through the spring pad 53, so that the spring piece 52 can be stably connected to the key board 2 or the display board 4, improving the stability of the device.
[0053] In some embodiments,
[0054] The elastic member further includes a base 51. The spring piece 52 is passed through the base 51, and both the first end and the spring pad 53 are exposed from the base 51.
[0055] The elastic member is further provided with a base 51. The base 51 adopts an injection molding structure to wrap the middle part of the spring piece 52 to provide a supporting effect for the spring piece 52. The first end of the spring piece 52 that abuts against the contact 21 is exposed from the base 51, and the spring pad 53 connected to the second end is also exposed from the base 51, facilitating soldering with the key board 2 or the display board 4.
[0056] Both the spring piece 52 and the spring pad 53 are copper sheets.
[0057] As Figure 1 shown, the spring piece 52 is mounted on the display board 4 through the spring pad 53 by the reflow soldering and chip mounting process. Corresponding welding positions, that is, the display board 4 pads, are provided on the display board 4, so that the spring piece 52 can be fixed on the display board 4. Correspondingly, the contact 21 is provided on the key board 2.
[0058] In the same mounting method, the elastic member can be arranged on the key board 2, and the contact 21 is arranged on the display board 4.
[0059] In some embodiments,
[0060] The display component further includes a panel 1, the panel 1 and the display board 4 are respectively arranged on both sides of the keypad 2, and the keypad 2 is in surface contact with the panel 1.
[0061] In the structure of the display component with the panel 1, the keypad 2 is arranged between the panel 1 and the display board 4, and the keypad 2 is attached to the panel 1. In this way, the keypad 2 can be controlled by touching the panel 1. That is, when the panel 1 is touched, the capacitance on the panel 1 will change. At this time, the keypad 2 senses the change in capacitance of the panel 1, generates an electrical signal, and transmits it to the display board 4 through the electrical connection structure of the elastic member and the contact 21 to perform the reaction and execution of the touch action.
[0062] In some embodiments,
[0063] The display component further includes a frame 3, one end of the frame 3 is fixedly connected to the panel 1; the keypad 2 and the display board 4 are arranged in the frame 3.
[0064] In the structural setting of the display component, a frame 3 is also provided to facilitate the accommodation of the keypad 2 and the display board 4 and reduce the entry of dust and other impurities; the frame 3 is a conventional ring structure, and one end is fixedly connected to the panel 1, thus forming an installation groove. The keypad 2 and the display board 4 are arranged in this installation groove and are blocked by the frame 3 on all sides.
[0065] In some embodiments,
[0066] The display board 4 is mounted in the frame 3 and is connected to the keypad 2 through the elastic sheet connection unit.
[0067] While ensuring the connection between the elastic sheet connection unit and the display board 4 and the keypad 2, the display board 4 is mounted in the frame 3 to limit the distance between the display board 4 and the keypad 2, which can avoid the elastic sheet being subjected to excessive pressure and affecting the service life of the elastic sheet connection unit.
[0068] In some embodiments,
[0069] The spring sheet 52 is in a state of compressive deformation and abuts against the contact 21.
[0070] The spring sheet 52 abuts against the contact 21 in a state of compressive deformation, improving the circuit stability of the electrical connection, so that the keypad 2 and the display board 4 will not easily have a power-off problem. And during disassembly and assembly, it is convenient for the two to separate, reducing the difficulty of disassembly and assembly.
[0071] For the above display component, the panel 1 is connected to the frame 3 through a pressure-holding process, the keypad 2 is attached to the panel 1 through a dispensing process, and the elastic member is mounted on the display board 4 through a reflow soldering process. The spring piece 52 of the elastic member contacts the contact 21 soldered on the keypad 2, and at the same time, the spring piece 52 itself undergoes compressive deformation, so as to realize an effective and reliable connection structure from the panel 1 to the frame 3, from the panel 1 to the keypad 2, from the contact 21 on the keypad 2 to the elastic member, and from the elastic member to the display board 4.
[0072] When a touch control is performed on the panel 1, the panel 1 generates a capacitance change. The keypad 2 attached to the back of the panel 1 can sense the capacitance change of the panel 1, and then generate an electrical control signal. The electrical control signal is transmitted to the elastic member on the display board 4 through the contact 21 on the keypad 2, and then transmitted to the display board 4 through the elastic member. The display board 4 responds to and executes the touch action.
[0073] The above structure and operation completely avoid signal loss caused by the damage of the connection medium between the display board 4 and the keypad 2, and ensure the signal transmission path. In addition, since the keypad 2 does not require a female socket, one reflow soldering process can be omitted during the production of the keypad 2, which also improves the production efficiency.
[0074] According to another aspect of the present application, a wire controller is provided, including the display component as described above.
[0075] According to another aspect of the present application, an air conditioner is provided, including the display component as described above or the wire controller as described above.
[0076] It is easy for those skilled in the art to understand that, on the premise of no conflict, the above embodiments can be freely combined and superimposed.
[0077] The above are only the preferred embodiments of the present application, and are not intended to limit the present application. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present application shall be included in the protection scope of the present application. The above is only the preferred implementation manner of the present application. It should be noted that for those of ordinary skill in the art, several improvements and variations can be made without departing from the technical principle of the present application, and these improvements and variations should also be regarded as the protection scope of the present application.
