Description

Technical Field

[0001] This application relates to the field of automotive parts technology, and in particular to a headrest and automobile. Background Technology

[0002] With the development of automotive technology, cars are becoming more and more diverse in their functions. For example, to improve the passenger experience, music headrests are installed above the back of car seats to play music to passengers in the seats.

[0003] In related technologies, the headrest has a speaker fixed inside. When driving a car, the sound emitted by the speaker of the music headrest interferes with the sound emitted by the car's navigation prompts. In order to hear the car's navigation prompts clearly, the driver needs to turn down the volume of the sound emitted by the speaker. In complex road conditions, the driver often has to adjust the volume of the speaker multiple times. In addition, when the car window is open, the sound emitted by the speaker is also easily interfered with by the wind noise outside the car, so the driver can only hear the music clearly by turning up the volume of the speaker.

[0004] In conclusion, the sound emitted by the speakers of the music headrest is prone to interference with external sounds, affecting the music experience of passengers. Summary of the Invention

[0005] Therefore, it is necessary to provide a headrest and car that addresses the problem that the sound emitted by the speakers of current music headrests easily interferes with external sounds, affecting the music experience of passengers.

[0011] The first direction, the second direction, and the third direction are arranged to intersect each other.

[0012] In one embodiment, the headrest includes two of the sound generators, and the rotation mechanism is configured to drive the two sound generators closer to or further away from each other in response to the elastic deformation of the elastic compression portion.

[0013] In one embodiment, the rotating mechanism includes a slider, two transmission components, and two rotating shafts, the slider being located between the two sound generators and connected to the elastic compression part;

[0014] The two transmission components are correspondingly arranged with the two rotating shafts, and each transmission component is connected to the slider and the corresponding rotating shaft.

[0015] Each of the said rotating shafts extends along the third direction and is rotatably connected to the housing;

[0016] The two sound generators are correspondingly arranged with the two rotating shafts, and each sound generator is connected to the corresponding rotating shaft.

[0017] The transmission component is configured to drive the corresponding rotating shaft to rotate relative to the housing about its own axis under the drive of the slider.

[0018] In one embodiment, the transmission component includes a connecting rod, a crank, and a turntable;

[0019] The connecting rod is hinged to the slider. The connecting rod can rotate relative to the slider about an axis parallel to the third direction at the hinge point between itself and the slider. The curved rod is rotatably connected to the end of the connecting rod away from the slider and can rotate relative to the connecting rod about an axis parallel to the third direction.

[0020] The turntable is rotatably connected to the end of the crank rod away from the connecting rod, and can rotate relative to the crank rod about an axis parallel to the third direction. The rotation axis passes through the turntable.

[0021] In one embodiment, the transmission member includes a guide rail disposed on the cavity wall of the receiving cavity along the third direction, the guide rail extending along the first direction;

[0022] The slider is slidably connected to the guide rail.

[0023] In one embodiment, the elastic compression portion has two sound-emitting areas on the side opposite to the receiving cavity, the two sound-emitting areas are arranged at intervals along the second direction, and the two sound-emitting areas are correspondingly arranged with the two sound generators;

[0024] Each of the sound-emitting areas is provided with at least one sound-emitting hole.

[0025] In one embodiment, the headrest includes a noise reduction component, which includes a processor and two sound detectors;

[0026] The two sound detectors are disposed within the receiving cavity and are correspondingly disposed to the two sound output areas. Each sound detector is used to detect the sound at the sound output hole located in the corresponding sound output area.

This, in turn, drives the rotating mechanism to rotate the sound generator relative to the housing around an axis parallel to the third direction, changing the direction of the sound emitted by the sound generator and reducing the distance between the driver's ear and the sound generator. This ensures that the sound is transmitted to the ear with minimal distance, even in the presence of external noise interference, without adjusting the volume of the sound generator, thus improving the driver's music experience.

A rotating mechanism connects the elastic compression section and the sound generator. The rotating mechanism is configured to drive the sound generator to rotate relative to the housing around an axis parallel to the third direction in response to the elastic deformation of the elastic compression section. This allows the driver to bring their head close to the elastic compression section to apply pressure, causing the elastic compression section to elastically deform towards the receiving cavity. This, in turn, drives the rotating mechanism to rotate the sound generator relative to the housing around an axis parallel to the third direction, changing the direction of the sound emitted by the sound generator and reducing the distance between the driver's ear and the sound generator. This ensures that the sound emitted by the sound generator is transmitted to the ear with minimal distance, even in the presence of external noise interference, without adjusting the volume of the sound generator, thus improving the driver's music experience. In summary, the car in this embodiment, through the above-described configuration, allows the driver to turn their head, change the distance between the sound generator and their ear, hear the sound emitted by the sound generator clearly, and achieve a better music experience.

[0052] Please see Figures 1 to 4 , Figure 1A schematic diagram of the structure of a headrest 1000 according to an embodiment of this application is shown. An embodiment of this application provides a headrest 1000 comprising: a housing 1100, at least two sound generators 1200, and a rotating mechanism 1300. The housing 1100 has a receiving cavity 1110. One surface of the housing 1100 along a first direction is an elastic compression portion 1120, which constitutes part of the cavity wall of the receiving cavity 1110. The elastic compression portion 1120 is provided with a sound outlet 1130 communicating with the receiving cavity 1110. The elastic compression portion 1120 can move towards the direction close to the receiving cavity 1110. The sound generator 1200 is disposed in the receiving cavity 1110 and arranged at intervals along the second direction. The rotating mechanism 1300 is disposed in the receiving cavity 1110 and connects the elastic compression part 1120 and the sound generator 1200. The rotating mechanism 1300 is configured to drive the sound generator 1200 to rotate relative to the housing 1100 about an axis parallel to the third direction in response to the elastic deformation of the elastic compression part 1120. The first direction, the second direction and the third direction are arranged to intersect each other.

[0053] In this embodiment, the headrest 1000 is provided with an elastic compression part 1120 that can elastically deform towards the receiving cavity 1110. A rotating mechanism 1300 connects the elastic compression part 1120 and the sound generator 1200. The rotating mechanism 1300 is configured to drive the sound generator 1200 to rotate relative to the housing 1100 about an axis parallel to a third direction in response to the elastic deformation of the elastic compression part 1120. This allows the driver to bring their head close to the elastic compression part 1120 to apply pressure to the elastic compression part 1120 when external sounds interfere with the sound emitted by the sound generator 1200 located in the receiving cavity 1110 of the headrest 1000. Pressure pushes the elastic compression part 1120 to elastically deform towards the receiving cavity 1110, thereby driving the rotating mechanism 1300 to drive the sound generator 1200 to rotate relative to the housing 1100 around an axis parallel to the third direction. This changes the direction of the sound emitted by the sound generator 1200, reducing the distance between the driver's ear and the sound generator 1200 until the sound emitted by the sound generator 1200 is transmitted to the ear with minimal distance. This ensures that even in the presence of external noise interference, the driver can still hear the sound emitted by the sound generator 1200 clearly without adjusting the volume, thus improving the driver's music experience. In summary, the headrest 1000 in this embodiment, through the above-mentioned design, allows the driver to rotate their head, changing the distance between the sound generator 1200 and the driver's ear, thus hearing the sound emitted by the sound generator 1200 clearly and achieving a better music experience.

[0054] Please see Figures 1 to 3In some embodiments, the headrest 1000 includes two sound generators 1200, and the rotation mechanism 1300 is configured to drive the two sound generators 1200 closer to or further away from each other in response to the elastic deformation of the elastic compression portion 1120.

[0055] In this embodiment, the two sound generators 1200 correspond to the driver's ears. When the sound emitted by the sound generators 1200 is interfered with by external noise, the driver brings his head close to the elastic compression part 1120 and applies pressure to the elastic compression part 1120, pushing the elastic compression part 1120 to elastically deform in the direction closer to the receiving cavity 1110. The elastic compression part 1120 drives the rotating mechanism 1300 to drive the two sound generators 1200 to move closer to each other, changing the direction of the sound emitted by each sound generator 1200 and reducing the distance between each sound generator 1200 and the corresponding ear, so that the driver's ears can clearly hear the sound emitted by the sound generators 1200, improving the driver's music experience.

[0056] Similarly, when external sounds are interfered with by the sound generator 1200, the driver moves their head away from the elastic compression part 1120 to reduce the pressure applied to the elastic compression part 1120. After the pressure is reduced, the elastic compression part 1120 moves away from the receiving cavity 1110 under the action of its own elastic restoring force. During this process, the rotating mechanism 1300 drives the two sound generators 1200 to move away from each other under the action of the elastic compression part 1120, changing the direction of the sound emitted by each sound generator 1200 and increasing the distance between each sound generator 1200 and the corresponding ear, so that the driver's ears can clearly hear the external sounds and improve the driver's experience.

[0057] Please see Figure 3 and Figure 4 In some embodiments, the rotating mechanism 1300 includes a slider 1310, two transmission members 1320, and two rotating shafts 1330. The slider 1310 is located between the two sound generators 1200 and connected to the elastic compression part 1120. The two transmission members 1320 are correspondingly arranged with the two rotating shafts 1330. Each transmission member 1320 connects the slider 1310 to the corresponding rotating shaft 1330. Each rotating shaft 1330 extends along a third direction and is rotatably connected to the housing 1100. The two sound generators 1200 are correspondingly arranged with the two rotating shafts 1330. Each sound generator 1200 is connected to the corresponding rotating shaft 1330. The transmission members 1320 are configured to drive the corresponding rotating shaft 1330 to rotate relative to the housing 1100 around its own axis under the drive of the slider 1310.

[0058] In this embodiment, when the sound emitted by the sound generator 1200 is interfered with by external noise, the elastic compression part 1120 moves closer to the receiving cavity 1110 along the first direction under the pressure applied by the driver's head, and drives the slider 1310 to move synchronously in the receiving cavity 1110. During this process, the slider 1310 drives the two transmission components 1320 to drive the rotating shaft 1330 connected to them to rotate. The two rotating shafts 1330 rotate in opposite directions around their own axes, so that the two sound generators 1200 move closer to each other.

[0059] Similarly, when external sounds are disturbed by the sound emitted by the sound generator 1200, the elastic compression part 1120 moves away from the receiving cavity 1110 along the first direction under the action of its own elastic restoring force, and drives the slider 1310 to move synchronously in the receiving cavity 1110. During this process, the slider 1310 drives the two transmission components 1320 to drive the rotating shaft 1330 connected to them to rotate. The two rotating shafts 1330 rotate in opposite directions around their own axes, so that the two sound generators 1200 move away from each other.

[0060] In some embodiments, the elastic compression portion 1120 is recessed toward the side near the receiving cavity 1110.

[0061] In this embodiment, by setting the elastic compression part 1120 to be recessed towards the side close to the receiving cavity 1110, the elastic compression part 1120 can better fit the driver's head.

[0062] In some embodiments, the distance between the two ends of the elastic compression portion 1120 along the second direction and the slider 1310 is equal.

[0063] In this embodiment, by setting the distance between the two ends of the elastic compression part 1120 along the second direction and the slider 1310 to be equal, the slider 1310 is located at the center of the elastic compression part 1120. However, since the elastic compression part 1120 is recessed towards the side closer to the receiving cavity 1110, the center of the elastic compression part 1120 is more prone to elastic deformation when subjected to pressure applied by the driver's head. Therefore, by setting the slider 1310 at the center of the elastic compression part 1120, the pressure required for the driver to cause elastic deformation of the elastic compression part 1120 can be reduced.

[0064] In some embodiments, the headrest 1000 includes a sensor (not shown) and a limiting component (not shown). The sensor is disposed on the housing 1100 and configured to detect the speed or acceleration of a vehicle (not shown) on which the headrest 1000 is installed. The limiting component is located within the receiving cavity 1110 and includes a baffle (not shown) and a drive member (not shown). The baffle is located between two sound generators 1200. The drive member is disposed on one side wall of the receiving cavity 1110 along a third direction. The drive member is electrically connected to the sensor and connected to the baffle. The drive member is configured to drive the baffle to move within the receiving cavity 1110 along a third direction when the sensor detects that the speed or acceleration of the vehicle is greater than a preset value, until the baffle moves to the side of the slider 1310 along a first direction, thereby preventing the elastic compression portion 1120 from being pushed by the inertial force of the driver's head when the driver accelerates the vehicle and undergoes elastic deformation.

[0065] Please see Figure 3 and Figure 4 In some embodiments, the transmission component 1320 includes a connecting rod 1321, a crank 1322, and a turntable 1323. The connecting rod 1321 is hinged to the slider 1310. The connecting rod 1321 can rotate relative to the slider 1310 about an axis parallel to a third direction at the hinge point between itself and the slider 1310. The crank 1322 is rotatably connected to the end of the connecting rod 1321 away from the slider 1310 and can rotate relative to the connecting rod 1321 about an axis parallel to a third direction. The turntable 1323 is rotatably connected to the end of the crank 1322 away from the connecting rod 1321 and can rotate relative to the crank 1322 about an axis parallel to a third direction. The rotating shaft 1330 passes through the turntable 1323.

[0066] In this embodiment, the slider 1310 drives the connecting rod 1321 in the transmission component 1320 to rotate around the hinge point between itself and the slider 1310. The connecting rod 1321 drives the corresponding crank 1322 to rotate around an axis parallel to the third direction. The crank 1322 drives the corresponding turntable 1323 to rotate around an axis parallel to the third direction. The turntable 1323 drives the rotating shaft 1330 to rotate around its own axis. The rotating shaft 1330 drives the sound generator 1200 to rotate relative to the housing 1100 around an axis parallel to the third direction.

[0067] In some embodiments, the rotation axis of the rotational connection between the crank 1322 and the turntable 1323 is parallel to the axis of the turntable 1323 itself and is arranged at intervals.

[0068] In some embodiments, the headrest 1000 includes a reset assembly (not shown), which includes a pressure sensor (not shown), an actuator (not shown), and a reset push plate (not shown). The pressure sensor is disposed on the side of the elastic compression portion 1120 away from the slider 1310 along a first direction. The pressure sensor is configured to detect the pressure applied by the driver's head to the elastic compression portion 1120. The reset push plate is located between two sound generators 1200 and is spaced apart from the slider 1310 along the first direction. The actuator is disposed in the receiving cavity 1110 and connected to the slider 1310. The actuator is electrically connected to the pressure sensor. The actuator is configured to drive the reset push plate to approach the slider 1310 along the first direction and push the slider 1310 away from the receiving cavity 1110 along the first direction when the pressure sensor detects that the pressure applied by the driver's head to the elastic compression portion 1120 is zero, until the elastic compression portion 1120 returns to the state when no elastic deformation has occurred.

[0069] Please see Figure 3 and Figure 4 In some embodiments, the transmission member 1320 includes a guide rail 1340, which is disposed on the cavity wall of the receiving cavity 1110 along a third direction. The guide rail extends along a first direction, and the slider 1310 is slidably connected to the guide rail 1340.

[0070] In this embodiment, when the elastic compression part 1120 undergoes elastic deformation, it drives the slider 1310 to move along the guide rail 1340 within the receiving cavity 1110.

[0071] In some embodiments, the elastic compression portion 1120 is provided with a protrusion 1150 on the side away from the slider 1310 along the first direction, and the protrusion 1150 protrudes toward the side away from the slider 1310.

[0072] In some embodiments, both the slider 1310 and the protrusion 1150 are made of rubber.

[0073] Please see Figure 3 and Figure 4 In some embodiments, the elastic compression portion 1120 has two sound-emitting regions (not shown) on the side opposite to the receiving cavity 1110. The two sound-emitting regions are arranged at intervals along the second direction. The two sound-emitting regions are correspondingly arranged with two sound generators 1200. Each sound-emitting region is provided with at least one sound-emitting hole 1130.

[0074] In this embodiment, the sound emitted by each sound generator 1200 is transmitted from the sound outlet 1130 in the corresponding sound outlet area and out of the receiving cavity 1110.

[0075] Please see Figure 3 and Figure 4In some embodiments, the headrest 1000 includes a noise reduction component 1400, which includes a processor 1410 and two sound detectors 1420. The two sound detectors 1420 are disposed in the receiving cavity 1110 and are correspondingly disposed in two sound output areas. Each sound detector 1420 is used to detect the sound at the sound output hole 1130 located in the corresponding sound output area. The processor 1410 is disposed in the receiving cavity 1110. The two sound generators 1200 and the two sound detectors 1420 are all electrically connected to the processor 1410.

[0076] In this embodiment, the sound detector 1420 detects the sound at the sound outlet 1130 in the sound area to detect the external noise heard by the human ear in the sound outlet area. The processor 1410 receives the data detected by the sound detector 1420, provides the voltage required for operation to the sound generator 1200, and controls the sound generator 1200 to generate a sound wave opposite to the noise according to the noise data detected by the sound detector 1420, thereby reducing the noise of the external environment and improving the listening experience of the driver using the headrest 1000.

[0077] In some embodiments, two sound detectors 1420 are disposed on the side of the elastic compression portion 1120 near the receiving cavity 1110.

[0078] Please see Figure 1 In some embodiments, the housing 1100 is provided with a guide groove 1140 on one side along a third direction. The guide groove 1140 extends along a second direction. The headrest 1000 includes a headrest rod 1500, which extends along a third direction. The headrest rod 1500 is located on the side of the housing 1100 where the guide groove 1140 is provided. One end of the headrest rod 1500 near the housing 1100 is slidably connected to the guide groove 1140 and can move within the guide groove 1140 along the second direction.

[0079] In this embodiment, the headrest rod 1500 is detachably connected to the seat (not shown) in the car. By adjusting the position of the headrest rod 1500 in the guide groove 1140, the operator changes the distance between the headrest 1000 and the seat in the second direction, thereby ensuring that the elastic compression part 1120 in the headrest 1000 is located on the side of the head of the driver of different heights along the first direction.

[0080] In some embodiments, the housing 1100 is provided with two headrest rods 1500 arranged at intervals along a second direction on one side of the housing 1100 along a third direction. The headrest 1000 includes two headrest rods 1500. The two headrest rods 1500 are located on the side of the housing 1100 where guide grooves 1140 are provided, and are correspondingly provided with the two guide grooves 1140. One end of each headrest rod 1500 near the housing 1100 is slidably connected to the corresponding guide groove 1140, and can move in the corresponding guide groove 1140 along the second direction.

[0081] In this embodiment, the operator can adjust the position of each headrest rod 1500 in the corresponding guide groove 1140, change the distance between the two headrest rods 1500 in the second direction, thereby ensuring that the headrest 1000 is better matched with the mounting holes on the seat, and making it easier and simpler to assemble the headrest 1000 with the seat.

[0082] Please continue reading. Figure 1 In some embodiments, the headrest rod 1500 is provided with a plurality of slots 1510, which are arranged at intervals along the extension direction of the headrest rod 1500.

[0083] In this embodiment, the operator can adjust the hooks (not shown) in the mounting holes on the seat to engage with the slots 1510 at different positions on the headrest rod 1500, thereby changing the distance between the headrest 1000 and the seat in the third direction, and thus meeting the driving needs of drivers of different heights.

[0084] This application also proposes a car (not shown) including the aforementioned headrest 1000.

[0085] In this embodiment, the car features an elastic compression section 1120 that can elastically deform towards the receiving cavity 1110. A rotating mechanism 1300 connects the elastic compression section 1120 and the sound generator 1200. The rotating mechanism 1300 is configured to drive the sound generator 1200 to rotate relative to the housing 1100 about an axis parallel to the third direction in response to the elastic deformation of the elastic compression section 1120. This allows the driver to bring their head close to the elastic compression section 1120 to apply pressure to the elastic compression section 1120 when external sounds interfere with the sound emitted by the sound generator 1200 located in the receiving cavity 1110 of the headrest 1000. The elastic compression part 1120 is pushed to deform elastically towards the receiving cavity 1110, thereby driving the rotating mechanism 1110 to drive the sound generator 1200 to rotate relative to the housing 1100 around an axis parallel to the third direction. This changes the direction of the sound emitted by the sound generator 1200, reducing the distance between the driver's ear and the sound generator 1200 until the sound emitted by the sound generator 1200 is transmitted to the ear with minimal distance. This ensures that even in the presence of external noise interference, the driver can still hear the sound emitted by the sound generator 1200 clearly without adjusting the volume, thus improving the driver's music experience. In summary, the car in this embodiment, through the above-mentioned settings, allows the driver to turn their head, change the distance between the sound generator 1200 and their ear, hear the sound emitted by the sound generator 1200 clearly, and achieve a better music experience.
