Therefore, they should not be construed as limitations on this application.

[0025] Embodiments of this application provide a remote control key that can be applied to vehicles or any other device equipped with a lock, without limitation. This application will primarily use a vehicle remote control key as an example for description.

[0026] Reference Figures 1-3 The remote control key includes a housing 1, a controller 2, and a sound generator 3. The controller 2 is located inside the housing 1 and is used to send control signals to the lock body. The sound generator 3 is electrically connected to the controller 2, and the controller 2 can control the sound generator 3 to emit sound.

[0027] The structure of the shell 1 is not limited, such as a cuboid structure, columnar structure, disk-shaped structure, disk-like structure, etc. Those skilled in the art can determine the specific structure according to actual usage requirements.

[0028] The controller 2 is installed inside the housing 1. The specific structure of the controller 2 is not limited. As an example, the controller 2 includes a circuit board 21. The circuit board 21 integrates a control circuit and a radio frequency module. The control circuit can generate lock body control signals such as locking signals and unlocking signals, and control the radio frequency module to send the lock body control signals to the lock body so that the lock body can complete locking, unlocking and other actions.

[0029] In addition to sending lock control signals, the RF module can also receive signals from users, such as signals sent by users through an app on mobile terminals (such as mobile phones, tablets, laptops, etc.). The RF module transmits and receives signals through an antenna, which can be integrated on circuit board 21 or independent of circuit board 21, without restriction.

[0030] The radio frequency module can be configured to receive and transmit signals via one or more of the following wireless communication protocols: Bluetooth, UWB (Ultra-Wideband), Wi-Fi, NFC, etc., without any restrictions.

[0031] The specific structure of the sound generator 3 is not limited, as long as it can produce sound. As an example, the sound generator 3 includes a buzzer, which can improve the recognizability of the sound emitted by the sound generator 3. The sound generator 3 can be placed inside or outside the housing 1, without limitation.

[0032] In addition to sending lock body control signals, controller 2 can also control the speaker 3 to emit sound. Specifically, controller 2 can be configured to receive control commands sent by the user via a wireless communication protocol, and then control the speaker 3 to emit sound based on the control commands.

[0033] In this embodiment, a sound generator 3 is provided in the remote key, so that when the remote key is lost, the user can send a control command to the controller 2 to control the sound generator 3 to emit a sound, and locate the remote key based on the sound, thereby increasing the probability of finding the remote key.

[0034] In some embodiments, refer to Figure 2 and Figure 3 The sound generator 3 is disposed inside the housing 1, and the housing 1 forms a sound hole (not shown in the figure). The remote control key includes a waterproof and breathable membrane 4, which is disposed inside the housing 1 and covers the sound hole.

[0035] Specifically, the sound-emitting part of the sound generator 3 can be positioned opposite to the sound-emitting hole to ensure the volume.

[0036] The waterproof and breathable membrane 4 can be a membrane structure with waterproof and breathable functions made of polytetrafluoroethylene, polyurethane, polyethylene, polypropylene, polyester or other polymer composite materials, and there are no restrictions on this.

[0037] In this embodiment, the sound generator 3 is placed inside the housing 1 and a corresponding sound hole is provided on the housing 1. This improves the aesthetics of the remote control key and helps protect the sound generator 3. Furthermore, the waterproof and breathable membrane 4 covers the sound hole. This prevents external moisture, dust and other impurities from entering the housing 1 through the sound hole and coming into contact with the sound generator 3, controller 2 and other components while enabling sound wave transmission, thus extending the service life of the remote control key.

[0038] In some embodiments, the controller 2 further includes a positioning module.

[0039] Here, the positioning module is used to acquire a location signal, which specifically refers to a signal that characterizes the current location of the controller 2 (remote key). As an example, the positioning module may include, but is not limited to, one or more of satellite positioning modules (such as GPS positioning, BeiDou satellite positioning, etc.), UWB positioning modules, cellular positioning modules, etc. The location signal acquired by the positioning module can be transmitted via a radio frequency module to an app on the user's mobile terminal (such as a mobile phone, laptop, tablet, etc.), enabling the user to locate the remote key based on the location signal sent by the controller 2.

[0040] It is understood that the sound emitted by the speaker 3 can only travel a limited distance. Therefore, in this embodiment, the controller 2 is further enabled to acquire and send a position signal. In this way, the user can first roughly locate the remote key based on the position signal sent by the controller 2. After the user arrives near the remote key, the speaker 3 is then controlled to emit a sound. This can further improve the probability of finding the remote key.

[0041] In some embodiments, refer to Figure 2 and Figure 3 The housing 1 includes a first sub-housing 11 and a second sub-housing 12, which are connected along a first direction. The controller 2 includes a circuit board 21, and the first direction is the thickness direction of the circuit board 21.

[0042] In this embodiment, the specific structural forms of the first sub-shell 11 and the second sub-shell 12 are not limited. The specific connection method of the first sub-shell 11 and the second sub-shell 12 is not limited, such as snap-fit, threaded connection, welding, bonding, etc.

[0043] In this embodiment, the housing 1 is configured as a split structure including a first sub-housing 11 and a second sub-housing 12. The first sub-housing 11 and the second sub-housing 12 are joined together along the thickness direction of the circuit board 21. This improves the structural compactness of the remote control key, meets the miniaturization requirements of the remote control key, and facilitates assembly.

[0044] In some embodiments, still refer to Figure 2 and Figure 3 The controller 2 includes a touch switch 22, which is disposed on the side of the circuit board 21 facing the first sub-housing 11 along the first direction. The first sub-housing 11 includes a flexible shell 111 and a support shell 112. The flexible shell 111 is disposed on the side of the support shell 112 away from the circuit board 21 along the first direction. The support shell 112 has a cutout area 112a at the position corresponding to the touch switch 22. The cutout area 112a penetrates the support shell 112 along the first direction. The flexible shell 111 is recessed into the cutout area 112a and can abut against the touch switch 22.

[0045] Here, the touch switch 22 is specifically used to trigger the control circuit on the circuit board 21, thereby generating a lock body control signal. The specific structure of the touch switch 22 is not limited; as an example, the touch switch 22 is a micro switch, thus improving control sensitivity. The number of touch switches 22 can be one or more, without limitation.

[0046] The flexible shell 111 specifically refers to a shell structure made of a flexible material. For example, the material of the flexible shell 111 includes, but is not limited to, silicone, rubber, polytetrafluoroethylene, polyurethane, and polyethylene. The supporting shell 112 is used to support the flexible shell 111. The supporting shell 112 can be a shell structure made of a rigid material or a shell structure made of a flexible material with a harderness than that of the flexible shell 111. There are no restrictions on this.

[0047] The flexible shell 111 and the supporting shell 112 can be connected by means of bonding, welding or other methods, and there are no restrictions on this.

[0048] The support shell 112 has a hollow area 112a at the position corresponding to the touch switch 22. Specifically, when projected orthogonally along the first direction, the projection of the hollow area 112a covers the projection of the touch switch 22. In embodiments where there are multiple touch switches 22, the hollow area 112a can be configured to correspond one-to-one with multiple touch switches 22, or one hollow area 112a can correspond to multiple touch switches 22; there is no limitation on this.

[0049] The flexible shell 111 is recessed into the hollow area 112a and can abut against the touch switch 22. Thus, in actual use, the user can press the recessed area of ​​the flexible shell 111 to deform the flexible shell 111 and apply force to the touch switch 22, thereby triggering the touch switch 22 and sending out the lock body control signal. As mentioned above, the support shell 112 may have multiple hollow areas 112a. In this embodiment, the flexible shell 111 may have multiple recessed areas corresponding to the multiple hollow areas 112a.

[0050] It should be noted that in this embodiment, the flexible shell 111 can directly abut against the touch switch 22, or it can indirectly abut against the touch switch 22 through other intermediate structures (such as the seal 5 mentioned below), and there is no limitation on this.

[0051] In this embodiment, the user can directly press the local recessed structure on the flexible shell 111 to complete the locking / unlocking operation, which facilitates blind operation and reduces the probability of accidental touch. Furthermore, in this embodiment, there is no need to set a movable button on the shell 1, which helps to improve the sealing performance of the shell 1 (no need to make holes in the flexible shell 111), providing better protection for the touch switch 22 and the circuit board 21, thereby improving the reliability and service life of the remote control key.

[0052] In some other embodiments, a movable button may also be formed on the first sub-housing 11, which the user can press to trigger the touch switch 22.

[0053] In some embodiments, the remote control key includes a seal 5 disposed within the housing 1, and along a second direction, the seal 5 covers the seam between the first sub-housing 11 and the second sub-housing 12, the first direction and the second direction intersecting.

[0054] As an example, the first direction and the second direction are perpendicular.

[0055] The specific material of the seal 5 is not limited, and it can be silicone, rubber, polytetrafluoroethylene, polyurethane, polyethylene, etc. The seal 5 can be made of rigid material or flexible material.

[0056] In this embodiment, by providing a sealing element 5 inside the housing 1 to cover the seam between the first sub-housing 11 and the second sub-housing 12, the sealing performance of the housing 1 is further improved, thereby enhancing the reliability and service life of the remote control key.

[0057] In some embodiments, refer to Figure 2 and Figure 3 The first sub-shell 11 has a plug-in wall 113 on the side facing the second sub-shell 12 along the first direction. The plug-in wall 113 is inserted into the second sub-shell 12 and fixedly connected to the second sub-shell 12.

[0058] The seal 5 includes a body portion 51 and a first flange portion 52. The body portion 51 is disposed between the first sub-housing 11 and the circuit board 21. Along the first direction, the body portion 51 covers the circuit board 21. The first flange portion 52 extends from the outer periphery of the body portion 51 and extends along the insertion wall 113. Along the second direction, the second sub-housing 12, the insertion wall 113 and the first flange portion 52 at least partially overlap.

[0059] In this embodiment, the fixed connection between the first sub-shell 11 and the second sub-shell 12 is achieved by inserting the insertion wall 113 into the second sub-shell 12, and the stepped surface 12a is used to limit the insertion wall 113 along the first direction.

[0060] The specific structural form of the insertion wall 113 and its specific connection method with the second sub-shell 12 are not limited. As an example, a first mating part 114 can be formed on the surface of the insertion wall 113 facing the second sub-shell 12 along the second direction, and a second mating part 121 can be formed on the surface of the second sub-shell 12 facing the insertion wall 113 along the second direction. The first mating part 114 and the second mating part 121 are engaged to achieve fixation. The first mating part 114 and the second mating part 121 can be a protrusion / groove, a male thread / female thread, etc. As another example, an adhesive layer is provided between the insertion wall 113 and the second sub-shell 12.

[0061] In the embodiment mentioned above, where the first sub-shell 11 includes a flexible shell 111 and a support shell 112, the insertion wall 113 is specifically formed in the support shell 112.

[0062] The body portion 51 of the seal 5 covers the circuit board 21 along the first direction, thus providing better protection for the circuit board 21. For example, see [reference needed]. Figure 2 One or more protrusions are formed on the side surface of the body portion 51 facing the circuit board 21 along the first direction. The protrusions abut against the circuit board 21, thereby improving the stability of the position of the seal 5 and helping to avoid electrical components on the circuit board 21 (such as the touch switch 22 mentioned above). As another example, an adhesive layer is provided on the side surface of the body portion 51 facing the first sub-housing 11.

[0063] The first flange 52 of the seal 5 extends from the outer periphery of the body 51. As an example, the first flange 52 and the body 51 can be formed as an integral structure.

[0064] Along the second direction, the second sub-shell 12, the insertion wall 113, and the first flange 52 overlap at least partially, such that the first flange 52 of the seal 5 can cover the connection position between the insertion wall 113 and the second sub-shell 12 (that is, cover the seam between the first sub-shell 11 and the second sub-shell 12).

[0065] In this embodiment, by configuring the seal 5 to include a body portion 51 and a first flange portion 52, the sealing effect of the seal 5 and its ability to protect the circuit board 21 and other electrical components of the controller 2 are improved, thereby further enhancing the reliability and service life of the remote control key.

[0066] In some embodiments, refer to Figure 2 and Figure 3 The second sub-shell 12 has a stepped surface 12a facing the first sub-shell 11 in a first direction. The seal 5 includes a second flange portion 53, which extends from the outer periphery of the first flange portion 52 away from the body portion 51 and extends in the second direction. One side surface of the second flange portion 53 abuts against the stepped surface 12a in the first direction, and the other side surface abuts against the insertion wall 113.

[0067] As an example, the body portion 51, the first flange portion 52, and the second flange portion 53 are formed as an integral injection molded structure.

[0068] In this embodiment, the second flange 53 is sandwiched between the insertion wall 113 of the first sub-shell 11 and the second sub-shell 12, and the three can form an interference fit. This can further improve the sealing performance and positional stability of the seal 5, and facilitate assembly.

[0069] In some embodiments, refer to Figures 1-3The remote control key includes a decorative ring 6 disposed between the first sub-shell 11 and the second sub-shell 12. The decorative ring 6 is at least partially exposed on the outer surface of the shell 1 and extends along the outer periphery of the first sub-shell 11 and / or the second sub-shell 12.

[0070] As an example, the first sub-shell 11 and the second sub-shell 12 surround to form a mounting groove. The mounting groove extends along the outer periphery of the first sub-shell 11 and the second sub-shell 12 to form an annular closed structure, and the mounting groove is open on one side along the second direction. The decorative ring 6 is disposed in the mounting groove.

[0071] The decorative ring 6 mainly serves a decorative purpose to meet aesthetic requirements. The materials of the decorative ring 6 and the first sub-shell 11 / second sub-shell 12 can be the same, different, or not completely the same, and there are no restrictions on this.

[0072] As an example, the first sub-shell 11 and the second sub-shell 12 are painted parts, and the decorative ring 6 is an electroplated part.

[0073] In some embodiments, refer to Figure 2 and Figure 3 The remote control key also includes a battery 7 and a charging coil 8. The battery 7 is disposed on the side of the circuit board 21 away from the first sub-casing 11 along the first direction and is electrically connected to the circuit board 21. The charging coil 8 is disposed between the battery 7 and the second sub-casing 12.

[0074] In this embodiment, the charging coil 8 enables wireless charging of the remote control key battery 7, improving user convenience. The specific implementation of the charging coil 8 can be found in relevant technologies in the art, and will not be elaborated upon here.
