[0079] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0080] Figure 1 A vehicle 1 according to one embodiment of this application is schematically shown. Figure 1 As shown, a seat 11 is provided in the passenger compartment of vehicle 1 for passengers to sit on.
[0081] Figure 2 The structure of seat 11 is shown schematically. (As shown) Figure 2 As shown, the seat 11 includes a seat body 2 and a headrest 3 mounted on the seat body 2.
[0082] like Figure 3As shown, the headrest 3 mainly includes a headrest body 301 and two insertion rods 302 (i.e., a first insertion rod 302a and a second insertion rod 302b) extending from the headrest body 301. A receiving structure (not shown) is constructed on the seat body 2. For example, the receiving structure consists of two insertion channels. The two insertion rods 302 are adapted to be detachably inserted into the two insertion channels respectively. In this way, the occupant can adjust the height of the headrest body 301 relative to the seat body 2 generally along the vertical direction Z of the headrest body 301 (i.e., the height direction of the seat 11) so that the position of the headrest body 301 matches the position of the occupant's head, thereby improving the occupant's riding experience. If necessary, the two insertion rods can also be pulled out from the two insertion channels to remove the headrest 3 from the seat body 2; or the two insertion rods can be inserted into the two insertion channels to install the headrest 3 onto the seat body 2. In some cases, the number of insertion rods can be one or more, depending on the actual situation. The following describes the seat headrest.
[0083] The seat headrest of the first embodiment
[0084] like Figure 4 As shown, the headrest body 301 of the seat headrest 3 generally includes a front cover assembly 303, a rear cover 304, a foam assembly 306, and multiple functional components 31 (see...). Figure 6 ).
[0085] Reference Figure 3 and Figure 4 The front cover assembly 303 and the rear cover 304 are assembled together and define a receiving cavity (not shown in the figure). Viewed as a whole, the front cover assembly 303 is closer to the occupant, and the rear cover 304 is further away from the occupant. A transverse direction X (generally perpendicular to the vertical direction Z) of the headrest body 301 is formed along the direction from the front cover assembly 303 to the rear cover 304.
[0086] The foam assembly 306 is disposed on the front cover assembly 303 and is located on the side of the front cover assembly 303 away from the rear cover 304 in the lateral direction X. For example, the foam assembly 306 includes a foam body 306c and a face shield 306d fitted onto the foam body 306c. The face shield 306d has a good tactile feel to improve the occupant's riding experience.
[0087] Multiple functional components 31 are assembled together with the headrest body 301. For example, the functional components 31 include a lifting module 314a and a fore-and-aft movement module 314b, which are used to move the seat headrest 3 up and down in the vertical direction Z and forward and backward in the lateral direction X relative to the seat body 2, respectively, to improve the comfort of the seat 11. In one embodiment, a base 307 is provided within a receiving cavity defined by the front cover assembly 303 and the rear cover 304, and the lifting module 314a and the fore-and-aft movement module 314b are mounted on the base 307. The lifting module and the fore-and-aft movement module are well known to those skilled in the art and will not be described in detail here. For example, the lifting module realizes the up and down movement of the seat headrest by using a vertical adjustment motor, and the fore-and-aft movement module realizes the fore-and-aft movement of the seat headrest by using a fore-and-aft adjustment motor.
[0088] Functional component 31 also includes a first heating module 311, a second heating module 312, and an airbag device 315. These functional components will be described in detail below.
[0089] like Figure 5a As shown, the headrest 3 also includes a converter 32 (as a control module). The converter 32 is also disposed inside the headrest body 301. For example, the front cover assembly 303 includes a front cover body 303a and a front cover bracket 303b, and the converter 32 is mounted on the front cover bracket 303b. The converter 32 includes a first electrical connector (as a first connector, not shown in the figure) and a second electrical connector (as a second connector, not shown in the figure).
[0090] Reference Figure 5a and Figure 6 The headrest 3 also includes multiple first cables 33 (as first lines). These first cables 33 electrically connect the aforementioned functional components 31 to the first electrical connectors of the converter 32. The headrest 3 also includes a second cable 34 (as a second line). The second cable 34 is electrically connected to a second electrical connector and extends beyond the headrest body 301. For example, a power supply 201 and a body control 202 (as functional source components) are provided within the seat body 2. The second cable 34 is electrically connected to the power supply 201 and the body control 202 to enable these functional components 31 to operate according to the occupant's instructions.
[0091] Looking at the headrest 3 as a whole, after using the converter 32, the first cables 33 no longer need to extend from the headrest body 3. Instead, only one second cable 34 extends from the headrest body 3 and is electrically connected to the external power supply 201 and the body controller 202. The smaller number of second cables 34 facilitates the disconnection and connection of the second cables 34 to the power supply 201 and the body controller 202, making it easier to install and remove the headrest 3 from the seat body 2.
[0092] The converter 32 receives electrical energy transmitted from the power source 201 via the second cable 34 and transmits the electrical energy to the corresponding functional component via the corresponding first cable. Furthermore, the converter 32 includes a control signal shunt (not shown) and / or a control signal processor (not shown). The control signal shunt receives signals from the body controller 202 and transmits these signals to the corresponding functional component via the corresponding first cable. The control signal processor receives signals from the body controller 202, processes these signals, and then transmits the processed signals to the corresponding functional component via the corresponding first cable. In this way, each functional component can operate according to the occupant's instructions. Such converters, control signal shunts, and control signal processors are well known to those skilled in the art and will not be described in detail here.
[0093] In one embodiment, there are multiple first electrical connectors (e.g., the number of first electrical connectors is equal to the number of first cables), and the number of second electrical connectors is equal to the number of second cables (e.g., the number of second electrical connectors is one). The converter 32 is provided with a socket 321 (e.g., ...). Figure 5a and Figure 5b (As shown), and these first and second electrical connectors are all integrated within the socket 321. The first cable 33 and the second cable 34 are inserted into the socket 321 and electrically connected to the corresponding first and second electrical connectors, respectively.
[0094] In one embodiment, refer to Figure 4 and Figure 5a At least portions of the first cables 33 and at least portions of the second cables 34 are intertwined, forming a cable assembly 309. In the cable assembly 309, the intertwined portions of the first cables 33 and the second cables 34 form a trunk section 335, and each first cable 33 also has a branch section 336 extending from the trunk section 335. There is one trunk section 335, which is inserted into a socket 321, so that the first cables 33 and the second cables 34 are electrically connected to the converter 32, and the multiple branch sections 336 are electrically connected to corresponding functional components 31. During the assembly of the headrest 2, connecting the trunk section 335 to the socket 321 achieves electrical connections between all the first cables 33 and the first electrical connectors, and between the second cables 34 and the second electrical connectors, simplifying the assembly operation of the headrest 2.
[0095] like Figure 5bAs shown, a plug 337 is provided at the end of the main section 335. The plug 337 integrates multiple first pins 337a that are electrically connected to multiple first cables 33 respectively, and second pins 337b that are electrically connected to second cables 34. Multiple first electrical connectors within the socket 321 are constructed as multiple third pins 323, and second electrical connectors are constructed as fourth pins 324. The multiple third pins 323 correspond to the multiple first pins 337a, and the fourth pins 324 correspond to the second pins 337b. Thus, after the plug 337 is inserted into the socket 321, the multiple third pins 323 are electrically connected to the multiple first pins 337a, and the fourth pins 324 are electrically connected to the second pins 337b, thereby realizing the electrical connection between the first cables 33 and the first electrical connectors, and the electrical connection between the second cables 34 and the second electrical connectors. According to this structure, the cable assembly 309 can be easily connected or disconnected from the converter 32, which is beneficial for the maintenance of the cable assembly 309 and / or the converter 32.
[0096] Alternatively, the converter can have two connectors (e.g., a first connector and a second connector). Multiple first electrical connectors are integrated into the first connector, and second electrical connectors are integrated into the second connector. This way, only the first cables are grouped together as a single unit, while the second cables are separate from these first cables. During the assembly of the seat headrest, these first cables are connected to the first connector, and the second cables are connected to the second connector.
[0097] In one embodiment, both connectors 302 are hollow tubular. A second cable 34 extends through the first connector 302a. Thus, the first connector 302a protects the second cable 34, reducing the risk of damage. Furthermore, the second cable is not visible from the outside environment, improving the seat's aesthetics. Additionally, with the converter 32, the first cables 33 do not need to extend from the headrest body 3 and pass through the first connector 302a; instead, only one second cable 34 passes through the first connector 302a. The number of second cables 34 is less than the number of first cables 33, therefore the diameter of the second cable 34 is also smaller than the diameter of the main section 335 of the cable assembly 309. In other words, the smaller diameter of the second cable 34 allows it to easily pass through the first connector 302a, making the assembly of the seat 11 easier. In one specific embodiment, the second cable may consist of four single wires with a diameter of approximately 4mm to 5mm; while the main section of the cable assembly consists of twelve single wires with a diameter of approximately 10mm.
[0098] For example Figure 5aAs shown, the seat 11 also includes a first plug-in structure 203. The first plug-in structure 203 includes a first male end 203a, a first female end 203b, and a first sleeve 203c. The first male end 203a is installed at the end of the first plug-in rod 302a away from the headrest body 301, and the second cable 34 is fixedly connected to the first male end 203a. The first female end 203b and the first sleeve 203c are disposed in the plug-in channel within the seat body 2. The first female end 203b is electrically connected to the power supply 201 and the body controller 202 within the seat body 2. When the first plug-in rod 302a is inserted into the corresponding plug-in channel, the first male end 203a is electrically connected to the first female end 203b under the guidance of the first sleeve 203c, thereby realizing the electrical connection of the second cable 34 to the power supply 201 and the body controller 202 within the seat body 2. When the first connector 302a is pulled out of the corresponding connector channel, the first female end 203a separates from the first female end 203b. This facilitates the separation and connection of the second cable 34 with the power supply 201 and the body controller 202 within the seat body 2, thereby making the removal and installation of the headrest 3 from the seat body 2 easier. The first plug-in structure 203 is well known to those skilled in the art and will not be described in detail here. Of course, other types of plug-in structures can be used depending on the actual situation, and there is no limitation here.
[0099] like Figure 7 As shown, the headrest body 301 (or foam assembly 306) includes a headrest 306a corresponding to the occupant's head and a neck brace 306b corresponding to the occupant's neck. The neck brace 306b is located below the headrest 306a along the vertical direction Z of the headrest body 301. For example, the upper portion of the foam assembly 306 along the vertical direction Z forms the headrest 306a, and the lower portion forms the neck brace 306b.
[0100] Functional component 31 includes a first heating module 311 disposed at the neck brace 306b. A first cable 33 includes a first connecting cable 331 that electrically connects the first heating module 311 to a first electrical connector of the converter 32. When the occupant sits on the seat 11, the first heating module 311 corresponds to the occupant's neck. Thus, the occupant can control the operation of the first heating module 311 as needed to heat the neck, which helps improve the occupant's riding experience. In one embodiment, the first heating module may be made of resistance wire. Of course, the first heating module may also be made of other suitable materials, and this is not limited thereto.
[0101] Functional component 31 also includes a second heating module 312 disposed at the headrest 306a. The second heating module 312 is electrically connected to a corresponding first electrical connector of the converter 32 via a second connecting cable 332 in the first cable 33. When the occupant sits on the seat 11, the second heating module 312 corresponds to the occupant's head. In this way, the occupant can control the operation of the second heating module 312 as needed to heat the head, which also helps to improve the occupant's riding experience. For example, in cold winter, when the occupant sits on the seat and rests their head on the seat headrest, the occupant can activate the second heating module 312 to quickly heat the seat headrest to a suitable temperature, dispel the cold, and thus provide the occupant with a comfortable riding experience.
[0102] Reference Figure 3 and Figure 4 The seat headrest 3 also includes a flexible cushion 308. The flexible cushion 308 is detachably mounted on the headrest 306a of the foam assembly 306 and faces the occupant's head. For example, the flexible cushion 308 is detachably assembled to the headrest body 301 via a strap 308a. The flexible cushion 308 has a pleasant tactile feel to provide the occupant with a comfortable riding experience.
[0103] like Figure 8 As shown, the second heating module 312 is assembled with the flexible pad 308. For example, the second heating module 312 includes a heating module body 312a and a wiring harness 312b electrically connected to the heating module body 312a. The heating module body 312a is disposed within the flexible pad 308. The wiring harness 312b extends outside the flexible pad 308 and is detachably connected to a second connecting cable 332, which facilitates the removal and installation of the flexible pad 308 from the headrest body 301.
[0104] Also refer to Figure 7 and Figure 9a The functional component 31 also includes an airbag device 315 disposed at the neck brace 306b. For example, the airbag device 315 is disposed on the side of the front cover body 303a of the front cover assembly 303 facing the foam assembly 306 and corresponds to the neck brace 306b.
[0105] like Figure 5a As shown, the seat headrest 3 also includes an air valve 35 (as another control module), which is also mounted on the front cover bracket 303b, for example. Air valves are well known to those skilled in the art, such as solenoid valves, and will not be described further here. The first cable 33 also includes a third connecting cable 333. The third connecting cable 333 electrically connects the air valve 35 to the first electrical connector of the converter 32 (e.g., ...). Figure 6 As shown). Figure 12 As shown, the gas valve 35 includes a first gas port 351 (as another first connector) and a second gas port 352 (as another second connector). Figure 11 As shown, the headrest 3 also includes a first air tube 36 (also serving as a first wiring) and a second air tube 37 (also serving as a second wiring). The first air tube 36 connects the airbag device 315 to the first gas interface 351. The second air tube 37 connects to the second gas interface 352 of the air valve 35 and extends beyond the headrest body 301. An air pump 204 is provided inside the seat body 2, and the second air tube 37 is connected to the air pump 204. Thus, the air valve 35 can inflate or deflate the airbag device 315 according to the occupant's instructions. The function of the airbag device 315 will be described below.
[0106] Similar to the method described above where only one second cable 34 extends beyond the headrest body 301 after using the converter 32, by using the air valve 35, the first air tubes 36 do not need to extend from the headrest body 301; instead, only one second air tube 37 extends from the headrest body 301. The fewer number of second air tubes 37 facilitates the disconnection and connection of the second air tubes 37 to the air pump 204, thereby facilitating the removal and installation of the seat headrest 3 from the seat body 2.
[0107] In one embodiment, the second air tube 37 extends through the hollow second connector 302b. The second connector 302b protects the second air tube 37 and makes it invisible from the outside environment, thus improving the aesthetics of the seat. Similar to the second cable 34 passing through the first connector 302a, after using the air valve 35, only one second air tube 37 needs to pass through the second connector 302b, facilitating seat assembly.
[0108] like Figure 5a As shown, the seat 11 also includes a second insertion structure 205. Similar to the first insertion structure 203, the second insertion structure 205 includes a second male end (not shown), a second female end (not shown), and a second sleeve (not shown). The second male end is installed at the end of the second insertion rod 302b away from the headrest body 301, and the second air tube 37 is fixedly connected to the second male end. The second female end and the second sleeve are disposed in insertion channels within the seat body 2. The second female end is connected to the air pump 204 within the seat body 2. When the second insertion rod 302b is inserted into the corresponding insertion channel, the second male end connects to the second female end under the guidance of the second sleeve, thereby enabling communication between the second air tube 37 and the air pump 204. When the second insertion rod 302b is pulled out from the corresponding insertion channel, the second male end separates from the second female end. This facilitates the separation and connection of the second air tube 37 with the air pump 204 within the seat body 2, thereby making the removal and installation of the seat headrest 3 from the seat body 2 easier. The second plug-in rod 302b is well known to those skilled in the art and will not be described in detail here. Of course, other types of plug-in structures may be used depending on the actual situation, and there are no restrictions here.
[0109] In one embodiment, the front cover assembly is capable of moving back and forth in the lateral direction relative to the rear cover. This allows for lateral adjustment of the position of the front cover assembly relative to the rear cover to improve seat comfort. In this case, the airbag device 315 can be disposed within the headrest body and offset from the neck rest, for example, generally within the headrest area and at least connected to the front cover assembly. Thus, when the airbag device is inflated, it expands and pushes the front cover assembly forward in the lateral direction relative to the rear cover. When the airbag device is deflated, it contracts, and the front cover assembly moves backward in the lateral direction relative to the rear cover. This achieves the lateral back-and-forth movement of the front cover assembly relative to the rear cover.
[0110] When the airbag device 315 is configured to correspond to the neck brace 306b, after the airbag device 315 is inflated, the neck brace 306b deforms slightly under the action of the airbag device 315 and fits better against the occupant's neck. This improves the support provided by the neck brace 306b to the occupant's neck and helps to improve the occupant's riding experience.
[0111] In one embodiment, by inflating and deflating the airbag device 315, the airbag device 315 can provide a massage effect on the occupant's neck, which also improves the occupant's riding experience. Figure 9a and Figure 10 As shown, the airbag device 315 includes a plurality of first airbags 315a. For example, these first airbags 315a are generally spaced apart along the length of the neck brace 306b. In this case, as... Figure 12 As shown, the air valve 35 includes multiple first gas ports 351. The first air tube 36 includes multiple first connecting air tubes 361, and each first airbag 315a is connected to a corresponding first gas port 351 via a first connecting air tube 361 (e.g., Figure 11 (As shown). Thus, the air valve 35 can periodically inflate and deflate each first airbag 315a at an appropriate frequency according to the occupant's instructions, allowing each first airbag 315a to independently expand or contract to press and massage the occupant's neck. Depending on the actual situation, these first airbags can also be arranged in other ways within the neck brace, as long as they provide the desired massage effect on the occupant's neck; details will not be elaborated here.
[0112] Reference Figure 7 The neck brace 306b includes a first side 305a facing the occupant and a second side 305b facing away from the occupant. That is, the first side 305a and the second side 305b are opposite each other along the lateral direction X of the headrest body 301. (See reference...) Figure 9a and Figure 10The first airbag 315a is disposed on the front cover body 303a and can contact the second side 305b of the neck brace 306b. For example, multiple grooves 305c are provided on the second side 305b of the neck brace 306b, and the first airbags 315a are respectively embedded in these grooves 305c. Thus, at each groove 305c, the thickness of the neck brace 306b is relatively thin (i.e., the thickness of the bottom of each groove 305c is relatively thin). Thus, when the first airbag 315a is inflated, the bottom of the groove 305c protrudes and deforms more towards the occupant's neck, making the massage effect of the first airbag 315a on the occupant's neck more obvious.
[0113] In one embodiment, the first heating module 311 described above is disposed on the first side 305a of the neck support 306b. Viewed as a whole, the first airbag 315a and the first heating module 311 are opposite each other along the lateral direction X, and both generally correspond to the occupant's neck. Thus, while the occupant uses the first airbag 315a to massage their neck, they can also use the first heating module 311 to heat their neck, which helps improve the massage effect and enhances the occupant's riding experience.
[0114] like Figure 9a As shown, the airbag device 315 also includes a second airbag 315b. The second airbag 315b is disposed on the side of the first airbag 315a away from the neck brace 306b. For example, the second airbag 315b is located between the first airbag 315a and the front cover body 303a. Figure 12 As shown, the gas valve 35 also includes a third gas interface 353 (as a first connector). The first gas pipe 36 also includes a third connecting gas pipe 362 (as shown). Figure 9b The second airbag 315b is connected to the third gas interface 353 via the third connecting air tube 362. After inflation, the second airbag 315b can push the first airbag 315a toward the neck brace 306b. In this way, the neck brace 306b fits better against the occupant's neck, which helps to improve the comfort of the seat.
[0115] like Figure 9bAs shown, there are multiple second airbags 315b. For example, the number of second airbags 315b is equal to the number of first airbags 315a. In the seat headrest 3, these second airbags 315b correspond one-to-one with these first airbags 315a. These second airbags 315b are all connected to the third gas interface 353 of the air valve 35 via a third connecting air tube 362 (for example, these second airbags are connected in series with each other), so that these second airbags 315b can be inflated or deflated simultaneously. When using the first airbags 315a and the second airbags 315b, these second airbags 315b inflate simultaneously so that these first airbags 315a fit more closely to the occupant's neck, thereby improving the massage effect of these first airbags 315a on the occupant's neck. It should be understood that, depending on the actual situation, these second airbags can also be controlled to inflate or deflate independently, which will not be elaborated here.
[0116] The second embodiment of the seat headrest
[0117] Figure 13 The internal structure of the headrest of the second embodiment is schematically shown. The headrest of the second embodiment is similar in structure to that of the first embodiment, the main difference being that the second embodiment includes an airbag device (not shown) and an air valve 35, but no converter. In this case, the second wiring includes a second air pipe 37. The second air pipe 37 connects to the second gas interface 352 of the air valve 35, passes through the second connector 302b, and extends beyond the headrest body 301. For example, the second air pipe 37 is connected to an air pump within the seat body. The headrest also includes a third cable 39. The third cable 39 is electrically connected to the air valve 35, passes through the first connector 302a, and extends beyond the headrest body. For example, the third cable 39 is connected to a power supply and / or a body control unit within the seat body.
[0118] It should be understood that other functional components (not shown in the figure) may also be provided inside the headrest of the seat in the second embodiment. A first cable electrically connected to these functional components extends through the first connector rod along with a third cable. The number of first cables can be determined according to actual circumstances and is not limited here.
[0119] The third embodiment of the seat headrest
[0120] Figure 14The internal structure of the headrest of the third embodiment is schematically shown. The headrest of the third embodiment is similar in structure to that of the first embodiment, with the main difference being that the third embodiment includes an airbag device (not shown) and other functional components (not shown), and a converter 32, but lacks an air valve. In this case, a second cable 34, electrically connected to the converter, passes through the first connector 302a and extends beyond the headrest body. For example, the second cable 34 is connected to a power supply and / or a body control unit within the seat body. A first air tube (not shown), connected to the airbag device, passes through the second connector 302b and extends beyond the headrest body 301. For example, the first air tube is connected to an air pump within the seat body.
