Description

Technical Field

[0001] This application relates to the field of remote control technology, specifically to a remote control key. Background Technology

[0002] The existing remote key does not have an internal limit structure. When subjected to stepping or other large external forces, the switch inside the remote key is easily deformed or damaged, rendering the remote key unusable and resulting in low security. Utility Model Content

[0003] In view of the above, it is necessary to provide a remote key to improve security.

[0004] This application provides a remote control key, including: The upper shell has a movable hole and a limiting part, the movable hole penetrates the upper shell, and the limiting part is provided on the side wall of the movable hole; The lower shell is detachably connected to the upper shell and forms a mounting cavity between the lower shell and the upper shell, the mounting cavity communicating with the movable hole; The circuit board is disposed in the lower housing and located in the mounting cavity; A switch is located on the side of the circuit board facing the upper shell and is electrically connected to the circuit board, for triggering the circuit board when pressure is applied; A flexible element covers the switch and is located in the mounting cavity, with the periphery of the flexible element being pressed between the upper shell and the lower shell; The button is movably inserted through the movable hole and has a stop portion adapted to the limiting portion, the stop portion and the limiting portion engaging.

[0005] In the aforementioned remote control key, the limiting part of the upper shell and the stop part of the button form a locking engagement, which can limit the travel of the button to avoid damage to the switch, thereby improving the security of the remote control key.

[0006] In some embodiments, one of the stop portion and the limiting portion is a protrusion and the other is a groove.

[0007] Therefore, the above settings can simplify the structure of the upper shell and buttons, thereby reducing the manufacturing cost of the remote control key.

[0008] In some embodiments, the sidewall of the movable hole is provided with a plurality of limiting portions, the plurality of limiting portions being arranged at intervals along the circumference of the movable hole, and the button having a plurality of stop portions, the plurality of stop portions being arranged one-to-one with the plurality of limiting portions.

[0009] Therefore, multiple stop parts and multiple limit parts can make the upper shell and the button form limits at multiple positions, so as to improve the accuracy of the button travel being limited.

[0010] In some embodiments, the flexible element and the circuit board are spaced apart along the axial direction of the movable hole.

[0011] Therefore, the flexible component is spaced apart from the circuit board, which allows the flexible component to have a certain amount of room to move relative to the circuit board in the direction of button movement, avoiding the circuit board from hindering the deformation of the flexible component, thereby ensuring the range of movement of the button.

[0012] In some embodiments, the surface of the flexible member facing the switch is arranged parallel to the surface of the switch facing the flexible member.

[0013] Therefore, the above settings can simplify the processing technology of flexible components and help reduce the manufacturing cost of flexible components.

[0014] In some embodiments, the flexible member has a receiving groove on its surface facing the switch, and the switch extends into the receiving groove and abuts against the bottom wall of the receiving groove.

[0015] Therefore, the positioning accuracy of flexible components and switches can be improved by using a receiving groove, which is beneficial to improving the assembly efficiency of flexible components.

[0016] In some embodiments, there are multiple active holes, multiple buttons and multiple switches, and each of the multiple active holes, multiple buttons and multiple switches is respectively provided in a one-to-one correspondence.

[0017] Therefore, the above settings can improve the functionality of the remote key.

[0018] In some embodiments, the circuit board has a through hole that extends through the circuit board along the axial direction of the movable hole, and the remote control key further includes: A support member, one end of which is connected to the lower shell, and the other end of which passes through the perforation and abuts against the flexible member.

[0019] Therefore, the support component, through perforations, forms an insertion fit with the circuit board, guiding the circuit board to the lower housing and improving the efficiency of circuit board installation. Furthermore, the support component abuts against the flexible component, providing a certain stop to the flexible component in the direction of button movement, preventing excessive force from the button from damaging the switch.

[0020] In some embodiments, the remote key further includes: A protective shell is fitted over the upper shell and the lower shell.

[0021] Therefore, a protective case can prevent external components from colliding with the upper and lower shells, which helps to extend the service life of the remote control key.

[0022] In some embodiments, the protective shell includes: The first end sleeve is fitted onto one end of the upper shell and one end of the lower shell; The second end sleeve is fitted onto the other end of the upper shell and the other end of the lower shell; A top sleeve is fitted onto the upper shell, and the two ends of the top sleeve are respectively engaged with the first end sleeve and the second end sleeve; A bottom sleeve is fitted onto the lower shell, and both ends of the bottom sleeve are respectively engaged with the first end sleeve and the second end sleeve.

[0023] Therefore, the above settings can improve the efficiency of disassembling and assembling the protective case. Attached Figure Description

[0033] The embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0034] Please see Figure 1 This application provides a remote control key 100, which can be applied to vehicles such as automobiles and trams, as well as to home appliances such as roller shutters and remote-controlled curtains, and can also be applied to other fields that require remote control.

[0035] Please see Figure 2 , Figure 3 and Figure 4 The remote control key 100 includes an upper shell 110, a lower shell 120, a circuit board 130, a switch 140, a flexible component 150, and a button 160. The upper shell 110 has a movable hole 110a and a limiting part 110b, the movable hole 110a penetrating the upper shell 110, and the limiting part 110b located on the side wall of the movable hole 110a. The lower shell 120 is detachably connected to the upper shell 110, forming a mounting cavity 100a between them, which communicates with the movable hole 110a. The circuit board 130 is located in the lower shell 120 and within the mounting cavity 100a. The switch 140 is located on the side of the circuit board 130 facing the upper shell 110 and is electrically connected to the circuit board 130, used to trigger the circuit board 130 upon pressure. The flexible element 150 covers the switch 140 and is located in the mounting cavity 100a, with the periphery of the flexible element 150 being pressed between the upper shell 110 and the lower shell 120. The button 160 is movably disposed in the movable hole 110a and has a stop portion 160a adapted to the limiting portion 110b, with the stop portion 160a and the limiting portion 110b engaging.

[0036] In the aforementioned remote control key 100, the limiting part 110b of the upper shell 110 and the stop part 160a of the button 160 form a locking cooperation, which can limit the travel of the button 160 to avoid damage to the switch 140, thereby improving the security of the remote control key 100.

[0037] Please see Figure 3In some embodiments, one of the stop portion 160a and the limiting portion 110b is a protrusion and the other is a groove.

[0038] In this embodiment, the stop portion 160a is a groove, and the limiting portion 110b is a protrusion. In other embodiments, the stop portion 160a may also be a protrusion, and the limiting portion 110b may be a groove.

[0039] Therefore, the above-mentioned configuration simplifies the structure of the upper shell 110 and the button 160, thereby reducing the manufacturing cost of the remote control key 100.

[0040] Please see Figure 3 In some embodiments, the sidewall of the movable hole 110a is provided with a plurality of limiting portions 110b, which are spaced apart circumferentially along the movable hole 110a. The button 160 has a plurality of stop portions 160a, which are correspondingly provided with the plurality of limiting portions 110b.

[0041] Therefore, the multiple stop portions 160a and multiple limit portions 110b enable the upper shell 110 and the button 160 to form limits at multiple positions, thereby improving the accuracy of limiting the travel of the button 160.

[0042] Please see Figure 4 In some embodiments, the flexible element 150 and the circuit board 130 are spaced apart along the axial direction of the movable hole 110a.

[0043] Therefore, the flexible component 150 is spaced apart from the circuit board 130, which allows the flexible component 150 to have a certain amount of room to move relative to the circuit board 130 in the direction of movement of the button 160, so as to avoid the circuit board 130 from hindering the deformation of the flexible component 150, thereby ensuring the range of movement of the button 160.

[0044] Please see Figure 4 In some embodiments, the surface of the flexible member 150 facing the switch 140 is arranged parallel to the surface of the switch 140 facing the flexible member 150.

[0045] Therefore, the above-mentioned settings can simplify the processing technology of the flexible component 150 and help reduce the manufacturing cost of the flexible component 150.

[0046] Please see Figure 5 In some embodiments, the flexible member 150 has a receiving groove 150a on its surface facing the switch 140, and the switch 140 extends into the receiving groove 150a and abuts against the bottom wall of the receiving groove 150a.

[0047] Therefore, the positioning accuracy of the flexible component 150 and the switch 140 can be improved by the receiving groove 150a, which is beneficial to improving the assembly efficiency of the flexible component 150.

[0048] Please see Figure 2 In some embodiments, there are multiple active holes 110a, multiple buttons 160 and multiple switches 140, and each of the multiple active holes 110a, multiple buttons 160 and multiple switches 140 is respectively provided in a one-to-one correspondence.

[0049] Therefore, the above settings can improve the functionality of the remote key 100.

[0050] Please see Figure 6 In some embodiments, the circuit board 130 has a through hole 130a that extends through the circuit board 130 along the axial direction of the movable hole 110a. The remote control key 100 also includes a support member 170. One end of the support member 170 is connected to the lower housing 120, and the other end of the support member 170 passes through the through hole 130a and abuts against the flexible member 150.

[0051] Therefore, the support member 170 forms an insertion fit with the circuit board 130 through the through hole 130a, which can guide the circuit board 130 to be installed into the lower shell 120, thereby improving the installation efficiency of the circuit board 130. In addition, the support member 170 abuts against the flexible member 150, which can form a certain stop for the flexible member 150 in the direction of movement of the button 160, so as to prevent the flexible member 150 from being damaged by excessive force from the button 160.

[0052] In this embodiment, there are multiple perforations 130a and multiple support members 170, and the multiple perforations 130a and multiple support members 170 are arranged in a one-to-one correspondence to improve the uniformity of support for the flexible member 150.

[0053] Please see Figure 1 and Figure 2 In some embodiments, the remote key 100 also includes a protective housing 180. The protective housing 180 is fitted onto the upper housing 110 and the lower housing 120.

[0054] Therefore, the protective shell 180 can prevent external components from colliding with the upper shell 110 and the lower shell 120, which helps to improve the service life of the remote control key 100.

[0055] In some embodiments, the protective shell 180 includes a first end sleeve 181, a second end sleeve 182, a top sleeve 183, and a bottom sleeve 184. The first end sleeve 181 is fitted onto one end of the upper shell 110 and one end of the lower shell 120, the second end sleeve 182 is fitted onto the other end of the upper shell 110 and the other end of the lower shell 120, the top sleeve 183 is fitted onto the upper shell 110, and both ends of the top sleeve 183 are respectively engaged with the first end sleeve 181 and the second end sleeve 182, and the bottom sleeve 184 is fitted onto the lower shell 120, and both ends of the bottom sleeve 184 are respectively engaged with the first end sleeve 181 and the second end sleeve 182.

[0056] Therefore, the above settings can improve the efficiency of disassembling and assembling the protective case 180.
