And can be adjusted as needed by those skilled in the art to suit particular applications.
Second, it should be noted that in the description of the present application, the terms of direction or positional relationship indicated by the terms "inside", "outside", and the like are based on the direction or positional relationship shown in the drawings, which are merely for convenience of description, and do not indicate or imply that a device or member must have a specific orientation, be constructed in a specific orientation, and be operated, and thus, should not be construed as limiting the present application.
Furthermore, it should be noted that, in the description of the present application, unless otherwise explicitly specified or limited, the terms "connected" and "connected" should be interpreted broadly, e.g., as being fixed or detachable or integrally connected; can be mechanically or electrically connected; the two components can be directly connected or indirectly connected through an intermediate medium, and the two components can be communicated with each other. The specific meaning of the above terms in the present application can be understood by those skilled in the art as the case may be.
The remote controller is provided with a plurality of keys which are generally divided into common keys and uncommon keys, and dust is easy to fall on the uncommon keys. Related art provides a remote controller including a sliding cover that can slide with respect to a front case to expose or hide an unusual key. The remote controller also comprises a first circuit board and a second circuit board, wherein the first circuit board is electrically connected with the commonly used keys, the second circuit board is electrically connected with the non-commonly used keys, and the first circuit board is electrically connected with the second circuit board through a lead so as to conduct a circuit between the first circuit board and the second circuit board. However, the wires have the characteristic of being bendable and deformable, so that the wires are easily pinched between the front shell and the rear shell of the remote controller and are pinched off, and further, the circuit between the first circuit board and the second circuit board cannot be conducted.
In view of the above problems, the inventor tried to provide cable fixing structures on the front case, the first circuit board, and the second circuit board, the cable fixing structures are used for limiting the displacement of the wires, and the wires are restrained by the cable fixing structures before the rear case is covered on the front case. However, the possibility of the wire being pinched between the front and rear cases is still not completely avoided. The inventor has then found that the zebra stripes may also connect two circuit boards, in particular, by placing the zebra stripes between a first circuit board and a second circuit board to conduct a circuit between the first circuit board and the second circuit board. The zebra stripes have stable performance and do not have the characteristic of bending extension, so that the zebra stripes are not easy to be pinched off, and the stable and reliable electrical connection relation between the first circuit board and the second circuit board is ensured.

The lower mounting casing 12 includes a lower panel 120 and a second surrounding wall 121, the second surrounding wall 121 is connected to the edge of the lower panel 120 and extends toward the rear casing, a sub-key mounting hole 1203 is formed in the lower panel 120, and the second key set is mounted in the sub-key mounting hole 1203 and electrically connected to the circuit board. Similar to the upper panel 110, the lower panel 120 may also have a square, rectangular or oval shape, which is not limited in this embodiment.
Fig. 3 is a partial structural schematic view of the remote controller in an embodiment of the application when the sliding cover is in a closed state, and fig. 4 is a partial structural schematic view of the remote controller in an embodiment of the application when the sliding cover is in an open state. Referring to fig. 3 to 4, the remote controller further includes a sliding cover 20, where the sliding cover 20 is slidably connected to the lower mounting housing 12, that is, the sliding cover 20 can slide relative to the lower mounting housing 12, so as to expose the second key set or hide the second key set. It can be understood that the first key group mainly comprises common keys, and the second key group mainly comprises uncommon keys, so that the uncommon keys of the remote controller can be shielded when the remote controller is not used, and dust can be prevented from falling on the uncommon keys.
It should be noted that the lower panel 120 is connected to the bottom of the first surrounding wall 111, and there is a gap between the outer side surface of the lower panel 120 facing the outside of the mounting cavity and the outer side surface of the upper panel 110 facing the outside of the mounting cavity, that is, the outer side surface of the upper panel 110 is not flush with the outer side surface of the lower panel 120, and a step surface is formed between the upper mounting shell 11 and the lower mounting shell 12.

Fig. 5 is a schematic view illustrating a connection between a front case and a circuit board at a second viewing angle according to an embodiment of the present application, and fig. 6 is an exploded schematic view illustrating a remote controller according to an embodiment of the present application. As shown in fig. 5, since the lower panel 120 of the lower mounting casing 12 is located behind the upper panel 110 of the upper mounting casing 11, in order to connect the display screen, the first key set and the second key set to the circuit board, the circuit board is divided into a first circuit board 30 and a second circuit board 40 in the embodiment, the second circuit board 40 is located behind the first circuit board 30, the display screen and the first key set are electrically connected to the first circuit board 30, and the second key set is electrically connected to the second circuit board 40.
The first circuit board 30 is opposite to the upper panel 110, and the first circuit board 30 is detachably connected to the upper panel 110, so that the first circuit board 30 can be detached from the remote controller for maintenance and replacement. Specifically, a first connecting stud 1103 is convexly arranged on the inner side surface of the upper panel 110 toward the rear shell, a first connecting through hole 33 is formed in the first circuit board 30, the first connecting through hole 33 and the first connecting stud 1103 are coaxially arranged, and a screw passes through the first connecting through hole 33 and then is matched with the first connecting stud 1103, so that the first circuit board 30 and the upper panel 110 are connected together through the screw. The first circuit board 30 may be located in a first accommodating cavity defined by the upper mounting housing 11, or may be located outside the first accommodating cavity.
The second circuit board 40 is removably connected to the lower mounting housing 12, and the second circuit board 40 is also removable from the remote control for ease of maintenance and replacement. For example, a second connection stud is disposed on the inner side surface of the lower panel 120, and a second connection through hole coaxial with the second connection stud is disposed on the second circuit board 40, so that the second circuit board 40 and the lower mounting shell 12 are screwed together.
It should be noted that the second circuit board 40 may be parallel to the lower panel 120, and in this case, if the upper panel 110 and the lower panel 120 are both perpendicular to the horizontal plane, the first circuit board 30 and the second circuit board 40 are also parallel to each other. Referring to fig. 5 and 6, the top end of the second circuit board 40 is also opposite to the bottom end of the first circuit board 30. It is understood that in order to oppose the first circuit board 30 to the second circuit board 40, the bottom end of the first circuit board 30 may extend downward beyond the bottom of the upper panel 110, and/or the top end of the second circuit board 40 may extend upward beyond the top of the lower panel 120.
As shown in fig. 6, the remote controller further includes a zebra stripe 60, the zebra stripe 60 is located between the first circuit board 30 and the second circuit board 40, and the zebra stripe 60 is in contact with both the first circuit board 30 and the second circuit board 40, so that the first circuit board 30 is electrically connected to the second circuit board 40 through the zebra stripe 60, and the circuit between the first circuit board 30 and the second circuit board 40 is further conducted. For example, zebra stripes 60 may be clamped between first circuit board 30 and second circuit board 40 to connect first circuit board 30 and second circuit board 40. The zebra stripes 60 are also called conductive rubber connectors, and the specific structure of the zebra stripes 60 can be found in the related art. For example, the zebra stripes 60 are formed by alternately layering and stacking conductive silica gel and insulating silica gel and then vulcanizing the conductive silica gel and the insulating silica gel.
The remote controller provided by the embodiment can be suitable for electrical equipment such as air conditioners, televisions, remote control illuminating lamps and the like so as to realize remote control. Specifically, be equipped with treater and signal receiver on the electrical equipment such as air conditioner, TV set, remote control light, this remote controller still includes infra-red transmitter 50, and infra-red transmitter 50 installs and installs the infrared signal of emitting outside the installation cavity in the past on the top of first circuit board 30, and signal receiver receives infrared signal and transmits the treater for electrical equipment, and treater analysis infrared signal carries out corresponding instruction according to the analytic result. The infrared emitter 50 may be, for example, an infrared diode, and accordingly, the infrared signal is infrared.
Through the above arrangement, the zebra stripes 60 replace wires to connect the first circuit board 30 and the second circuit board 40, the zebra stripes 60 are stable and reliable in performance, compared with the wires, the zebra stripes 60 cannot be bent and extended, and therefore the zebra stripes 60 are prevented from being clamped between the front shell 10 and the rear shell, and the circuit between the first circuit board 30 and the second circuit board 40 can be conducted.
With continued reference to fig. 5 and 6, the remote controller may further include a mounting bracket 70, the mounting bracket 70 is located between the first circuit board 30 and the second circuit board 40, a receiving through hole is formed on the mounting bracket 70, the zebra stripe 60 is received in the receiving through hole and contacts with the first circuit board 30 and the second circuit board 40, and the mounting bracket 70 is further fastened to the top end of the second circuit board 40. So designed, on the one hand, the mounting bracket 70 provides a mounting space for the zebra stripes 60, and on the other hand, the top end of the second circuit board 40 can be supported, so that the second circuit board 40 can be stably mounted.
The mounting bracket 70 may be made of plastic, which results in a lower weight and lower cost of the mounting bracket 70 as compared to a mounting bracket 70 made of metal. The mounting bracket 70 may be a rod-shaped structure or a block-shaped structure, which is not limited in this embodiment. Fig. 7 is a schematic structural diagram of a mounting bracket in a first viewing angle according to an embodiment of the present application. In the example shown in fig. 7, the mounting bracket 70 is a mounting block, the mounting block is provided with a receiving through hole 71 for receiving the zebra stripes 60, and when the mounting block is disposed between the first circuit board 30 and the second circuit board 40, the center line of the receiving through hole 71 is perpendicular to the first circuit board 30. The zebra stripes 60 can be in interference fit with the accommodating through holes 71, so that the zebra stripes 60 can be stably embedded in the accommodating through holes 71. And, both front and back sides of zebra stripes 60 exceed receiving through holes 71 to contact with first circuit board 30 and second circuit board 40. Specifically, when the mounting block is a long bar-shaped block, and the long bar-shaped mounting block extends in the left-right direction of the remote controller, the width of the zebra stripes 60 in the direction of the center line of the accommodating through hole 71 is larger than the size of the accommodating through hole 71 in the direction of the center line thereof.
The top fastening of the mounting bracket 70 to the second circuit board 40 can be achieved as follows:
for example, the mounting bracket 70 may be screwed to the second circuit board 40. Taking the mounting bracket 70 as an example of a mounting block, a third connecting stud is convexly arranged on the back surface of the mounting block facing the rear shell, a third connecting through hole is arranged at the top end of the second circuit board 40, the third connecting through hole and the third connecting stud are coaxially arranged, and a screw passes through the third connecting through hole and is matched with the third connecting stud.
For another example, the mounting bracket 70 may be snap-fit to the second circuit board 40. Referring to fig. 6 and 7, taking the mounting bracket 70 as an example of a mounting block, a first clamping column 73 may be disposed on a back surface of the mounting block, a first clamping hole 41 is disposed at a top end of the second circuit board 40, and the first clamping column 73 is clamped with the first clamping hole 41. Compared with the screw connection of the mounting bracket 70 and the second circuit board 40, the clamping connection mode does not need to be assembled and disassembled by means of a disassembling tool, and the mounting efficiency is high.
Further, the number of the first clamping columns 73 can be multiple, correspondingly, the second circuit board 40 is provided with a plurality of first clamping holes 41, and each first clamping column 73 is matched with one first clamping hole 41. Thus, the number of the clamping parts of the mounting bracket 70 and the first circuit board 30 is increased, so that the connection relationship between the mounting bracket 70 and the first circuit board 30 is more reliable. In fig. 7, the first clamping columns 73 are two, and the two first clamping columns 73 are respectively arranged at the left side and the right side of the accommodating through hole 71, so that the clamping action of the mounting bracket 70 and the first circuit board 30 is uniformly distributed at the two ends of the mounting block, and the two ends of the mounting bracket 70 are clamped, thereby being beneficial to improving the mounting stability of the mounting bracket 70.
The mounting bracket 70 can also be fastened and connected with the first circuit board 30, which not only improves the mounting stability of the mounting bracket 70, but also enables the bottom end of the first circuit board 30 to be stable. The connection manner of the mounting bracket 70 and the first circuit board 30 may refer to the connection manner of the mounting bracket 70 and the second circuit board 40. For example, taking the mounting bracket 70 as an example of a mounting block, as shown in fig. 6 and 8, a second clamping column 74 is disposed on a front surface of the mounting block facing the front shell 10, a second clamping hole 31 is disposed at a bottom end of the first circuit board 30, and the second clamping column 74 is clamped with the second clamping hole 31. The number of the second locking columns 74 may also be multiple, and correspondingly, the first circuit board 30 is provided with a plurality of second locking holes 31, so that the connection relationship between the mounting bracket 70 and the second circuit board 40 is more reliable. Fig. 8 is a schematic structural diagram of a mounting bracket in a second viewing angle according to an embodiment of the present application. In fig. 8, there are 3 second latching legs 74, two of the second latching legs 74 are respectively disposed at the left and right sides of the accommodating through-hole 71, and one of the three second latching legs 74 is disposed above the accommodating through-hole 74.
In addition, it should be noted that the matching relationship between the first clamping column 73 and the first clamping hole 41 and the matching relationship between the second clamping column 74 and the second clamping hole 31 can also play a role of positioning, so that the installer can find the installation position of the installation bracket 70.
