DETAILED DESCRIPTION

[0048] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0049] The directional nouns involved in the embodiments of the present application, such as "upper", "lower", "side", etc., are generally represented by Figure 1 The relative relationship of the orientation shown in the figure is used as the basis, and these orientation terms are used only to more clearly describe the relationship between structures, not to describe absolute orientation. When the product is placed in different postures, the orientation may change, for example, "up" and "down" may be interchangeable.

[0050] Unless otherwise defined, all technical terms used in the embodiments of the present application have the same meanings as commonly understood by those of ordinary skill in the art.

[0051] In order to make the technical solutions and advantages of the present application more clear, the implementation methods of the present application will be further described in detail below with reference to the accompanying drawings.

[0052] like Figure 1 and Figure 2 As shown, the present application provides a switch module, which includes a housing 1 , a button assembly 2 and a fragrance assembly 3 .

[0053] Specifically, the switch module is applied to vehicles. As a way to implement human-computer interaction in the vehicle, the switch module can control the working status of relevant functional modules in the vehicle, where the functional modules can be audio modules, display modules, air-conditioning modules, etc. The switch module can adjust the volume, start and stop, set temperature, brightness and other states.

[0054] The housing 1 has a first accommodating chamber 11. Figure 2 As shown, the housing 1 is roughly cylindrical, and an opening is formed at the upper end of the housing 1.

[0055] The key assembly 2 is partially accommodated in the first accommodating cavity 11. The key assembly 2 can move along its own axial direction relative to the shell 1. The key assembly 2 is provided with a fragrance outlet hole 225 for communicating with the external environment.

[0056] The button assembly 2 passes through the opening at the upper end of the shell 1, with one part located in the first accommodating cavity 11 and the other part located outside the shell 1. The passenger can press the top pressing surface of the button assembly 2 to make the button assembly 2 move linearly downward along its own axis, thereby adjusting the working state of the functional module.

[0057] The fragrance component 3 is inserted into the button component 2. Figure 1As shown, the key assembly 2 is roughly cylindrical and hollow, and the fragrance assembly 3 is located in the inner space of the key assembly 2, making full use of the volume of the key assembly 2, so that the fragrance assembly 3 does not need to occupy additional space in the vehicle. The fragrance outlet 225 of the key assembly 2 can be connected to the external environment, so the fragrance assembly 3 can emit fragrance into the space inside the vehicle through the fragrance outlet 225.

[0058] For example, Figure 3 As shown, the fragrance component 3 is roughly cylindrical, and includes a fragrance shell 31 and a fragrance stick 32 arranged in the fragrance shell 31. The fragrance shell 31 is provided with at least one first through hole 313 so that the fragrance of the fragrance stick 32 can be spread to the outside of the fragrance shell 31.

[0059] The switch module provided in the embodiment of the present application inserts the fragrance component 3 into the button component 2. While controlling the relevant functional modules through the button component 2, the volume of the button component 2 is utilized to integrate the fragrance component 3 into the button component 2, so that the fragrance component 3 emits fragrance through the fragrance outlet 225 provided on the button component 2, thereby saving the space occupied by the fragrance component 3 in the vehicle and helping to improve the space utilization rate in the vehicle.

[0060] In a further embodiment, Figure 1 As shown, the switch module also includes a knob assembly 4, which is partially accommodated in the first accommodating cavity 11. The knob assembly 4 can rotate relative to the shell 1, the button assembly 2 is detachably installed in the knob assembly 4, and the fragrance assembly 3 is detachably connected to the button assembly 2.

[0061] The knob assembly 4 is roughly in the shape of a cylindrical shell, the button assembly 2 is at least partially located inside the knob assembly 4, a part of the knob assembly 4 is located in the first accommodating cavity 11, and the other part is located outside the shell 1, so that the passenger can control the knob assembly 4 to rotate it around its own central axis.

[0062] Exemplarily, by rotating the knob assembly 4, the user can adjust the volume, brightness, wind force and other parameters of the functional module to adjust the working state of the functional module.

[0063] Optionally, the button assembly 2 and the knob assembly 4, and the button assembly 2 and the fragrance assembly 3 can be detachably connected by means of snap connection, threaded connection, mortise and tenon connection, etc.

[0064] By detachably connecting the button assembly 2 to the knob assembly 4 and the fragrance assembly 3, it is convenient to remove the button assembly 2 from the knob assembly 4 and replace it with a new fragrance assembly 3, thereby improving the installation convenience of the fragrance assembly 3 and the flexibility of the switch module.

[0065] In a further embodiment, Figure 4 and Figure 5 As shown, the key assembly 2 includes a key cap 21 and a key body 22. The first end of the key body 22 is connected to the key cap 21. The second end of the key body 22 is provided with a first mounting hole 221. The key body 22 has a second accommodating cavity 222. The fragrance assembly 3 extends through the first mounting hole 221 into the second accommodating cavity 222.

[0066] like Figure 5 As shown, the longitudinal section of the button assembly 2 is T-shaped, the outer diameter of the button cap 21 is larger than the outer diameter of the button body 22, and the top surface of the button cap 21 is the pressing surface of the button assembly 2. The user drives the button assembly 2 to move downward by pressing the button cap 21.

[0067] The first end and the second end of the button body 22 are opposite ends of the button body 22 in the axial direction. The first mounting hole 221 is located at the end of the button body 22 away from the button cap 21. The first mounting hole 221 is used to allow the fragrance component 3 to pass through so as to install the fragrance component 3 in the button body 22.

[0068] For example, Figure 5 As shown, a mounting plate 223 is further provided at the first end of the key body 22. The mounting plate 223 is spaced apart from the key cap 21 along the axial direction of the key assembly 2. A limiting boss 224 is convexly provided on the mounting plate 223. The limiting boss 224 is annular and protrudes toward the second end of the key body 22 relative to the mounting plate 223. The shape and size of the limiting boss 224 are respectively adapted to the shape and size of the end of the fragrance component 3, so that the end of the fragrance component 3 is just inserted into the limiting boss 224. When the end of the fragrance component 3 abuts against the mounting plate 223, the fragrance component 3 is installed in place.

[0069] The key body 22 is provided with a fragrance outlet 225. Figure 1 As shown, there is a gap 211 between the button cap 21 and the knob assembly 4, and the gap 211 is connected to the fragrance outlet 225 and the external environment respectively.

[0070] like Figure 5 As shown, the fragrance outlet 225 is provided on the side wall of the button body 22 and is located between the mounting plate 223 and the button cap 21 , wherein the mounting plate 223 is further provided with at least one second through hole 2231 , and the second through hole 2231 is located on the outer side of the limiting boss 224 .

[0071] The button cap 21 and the knob assembly 4 are arranged at intervals along the radial direction of the switch module, so that an annular gap 211 is formed between the button cap 21 and the knob assembly 4, and the fragrance of the fragrance assembly 3 can be spread to the external environment of the switch module through the second through hole 2231, the fragrance outlet hole 225 and the gap 211 on the mounting plate 223 in sequence.

[0072] like Figure 3 As shown, a first limiting structure 311 is protruded from the outer wall of the fragrance component 3 , and the first limiting structure 311 is used to abut against the inner wall of the second end of the button body 22 .

[0073] Specifically, the first limiting structure 311 is protruding from the outer wall of the fragrance shell 31, and the first limiting structure 311 is annular. Optionally, the first limiting structure 311 is continuously distributed around the central axis of the fragrance shell 31, or the first limiting structure 311 is discontinuously distributed around the central axis of the fragrance shell 31.

[0074] When the fragrance component 3 is installed in place, the first limiting structure 311 is located in the second accommodating cavity 222 and abuts against the inner wall of the second end of the button body 22, thereby limiting the fragrance component 3 in the axial direction and preventing the fragrance component 3 from separating from the button component 2.

[0075] It can be understood that the outer diameter of the first limiting structure 311 is slightly larger than the inner diameter of the first mounting hole 221. In the process of inserting the fragrance component 3 into the second accommodating cavity 222 or removing the fragrance component 3 from the second accommodating cavity 222, the installation and removal of the fragrance component 3 are achieved by relying on the slight deformation of the first mounting hole 221 at the second end of the button body 22.

[0076] The outer wall of the first limiting structure 311 is in the shape of an arc surface, and the longitudinal section of the first limiting structure 311 is in the shape of a semicircle. With this arrangement, it is convenient to insert the fragrance component 3 into the second accommodating cavity 222 with the help of the smooth arc surface, and it is convenient to take the fragrance component 3 out of the second accommodating cavity 222 along the arc surface, and while limiting the fragrance component 3 by the first limiting structure 311, it avoids affecting the normal disassembly and assembly of the fragrance component 3.

[0077] Alternatively, if Figure 3 As shown, the outer wall of the fragrance component 3 is further convexly provided with a fourth limiting structure 312, which is annular and continuously distributed around the central axis of the fragrance component 3, and the fourth limiting structure 312 and the first limiting structure 311 are spaced apart along the axial direction of the fragrance component 3, and the fourth limiting structure 312 is located on the side of the first limiting structure 311 away from the button cap 21. When the fragrance component 3 is installed in place, the first limiting structure 311 and the fourth limiting structure 312 are respectively located on both sides of the axial direction of the second end of the button body 22, which further strengthens the limiting effect on the fragrance component 3 and prevents the fragrance component 3 from moving along the axial direction.

[0078] In a further embodiment, Figure 1 As shown, the switch module also includes a circuit board 5, which is arranged in the first accommodating cavity 11, the knob assembly 4 is installed on the circuit board 5 and electrically connected to the circuit board 5, and the circuit board 5 is provided with an elastic connector 51 for connecting with the fragrance assembly 3.

[0079] Specifically, integrated circuits and electronic components are disposed on the circuit board 5 , which is located in the first accommodating cavity 11 and mounted on the bottom of the housing 1 , and the knob assembly 4 , the button assembly 2 and the fragrance assembly 3 are all located above the circuit board 5 .

[0080] Since the knob assembly 4 is electrically connected to the circuit board 5, electrical signals can be transmitted between the knob assembly 4 and the circuit board 5, so that the knob assembly 4 can adjust the working state of the relevant functional modules through its own rotational movement. Furthermore, the button assembly 2 is also electrically connected to the circuit board 5, so that the button assembly 2 can adjust the working state of the relevant functional modules through its own axial movement. The electrical connection method between the knob assembly 4 and the circuit board 5 and the method for realizing the adjustment function of the knob assembly 4, the electrical connection method between the button assembly 2 and the circuit board 5 and the line of sight method for adjusting the function of the button assembly 2 are all prior arts and will not be elaborated here.

[0081] The elastic connector 51 on the circuit board 5 is elastically connected to the fragrance component 3, and the elastic connector 51 can produce elastic movement along the axial direction of the fragrance component 3, so that the key component 2 can move downward along the axial direction when subjected to downward pressure, and rebound upward along the axial direction when the downward pressure disappears. Exemplarily, the elastic connector 51 is an elastic contact.

[0082] Optionally, the fragrance component 3 further includes a fragrance chip 33, such as Figure 1 As shown, the fragrance chip 33 is installed at the bottom of the fragrance shell 31 and is electrically connected to the elastic connector 51. The relevant electronic components on the circuit board 5 can identify the type of the fragrance chip 33 and obtain the information contained in the fragrance chip 33, wherein the information contained in the fragrance chip 33 includes but is not limited to the fragrance type and usage time of the fragrance component 3.

[0083] In a further embodiment, Figure 2 As shown, the switch module further includes an ambient light assembly 6 , which is mounted on the outer wall of the housing 1 and electrically connected to the circuit board 5 .

[0084] Through this setting, the atmosphere light assembly 6, the fragrance assembly 3, the button assembly 2 and the knob assembly 4 are integrated into one, which not only saves space inside the vehicle, but also effectively improves the product texture of the switch module and the exquisiteness and high-end feel of the car interior, providing users with a good visual and olfactory experience.

[0085] Optionally, the working mode of the atmosphere light assembly 6 is associated with the type of the fragrance assembly 3, and the related electronic components on the circuit board 5 can identify the type of the fragrance chip 33, and the control circuit on the circuit board 5 can control the atmosphere light assembly 6 to operate in a corresponding working mode according to the type of the fragrance chip 33. Among them, different working modes of the atmosphere light assembly 6 can correspond to different luminous colors, flashing modes, luminous brightness, etc., and the user can also set the working mode of the atmosphere light assembly 6 by himself through the vehicle's interactive module.

[0086] like Figure 6 As shown, the housing 1 includes a main body 12 and a neck 13 connected to each other. The neck 13 is located at one end of the main body 12, and the outer diameter of the neck 13 is smaller than the outer diameter of the main body 12. The outer wall of the neck 13 is provided with a mounting groove 131, which is annular and continuously distributed around the central axis of the housing 1, and the atmosphere lamp assembly 6 is installed in the mounting groove 131.

[0087] Exemplarily, an end of the shell neck 13 away from the main body 12 is provided with an outer flange 132, which is annular and extends outwardly along the radial direction of the shell neck 13. The outer flange 132 is used to abut against the knob assembly 4. By providing the outer flange 132, the contact area between the shell 1 and the knob assembly 4 is increased, so that the outer flange 132 can better support the knob assembly 4.

[0088] For example, Figure 6 As shown, the end face of the main body 12 connected to the shell neck 13 is conical, and the conical vertex of the extended surface of the end face is located in the first accommodating cavity 11, so that the height of the inner edge of the end face is lower than the height of the outer edge of the end face. Through this arrangement, the light emitted by the atmosphere lamp assembly 6 is fully irradiated on the end face of the main body 12 connected to the shell neck 13, thereby improving the visual effect of the atmosphere lamp.

[0089] In one embodiment, Figure 1 As shown, the switch module also includes a fan assembly 7, which is installed at one end of the shell 1. The shell 1, the circuit board 5 and the button body 22 are respectively provided with ventilation holes 121, and the multiple ventilation holes 121 are interconnected to form a fragrance outlet channel connected to the fragrance outlet hole 225.

[0090] The fan assembly 7 is located at one end of the housing 1 away from the button cap 21. The fan assembly 7 is used to speed up the air flow speed, so as to quickly spread the fragrance of the fragrance assembly 3 to the external environment of the switch module.

[0091] Exemplarily, the fan assembly 7 includes a fan housing 71 and a fan body (not shown in the figure) located inside the fan housing 71, and the fan body is electrically connected to the circuit board 5 through a cable. Figure 1As shown, an air inlet 711 is provided on the bottom wall of the fan housing 71, and air in the external environment enters the fan housing 71 through the air inlet 711, and further flows along the fragrance outlet channel driven by the fan body.

[0092] Specifically, after the air in the external environment enters the fan housing 71 through the air inlet 711, it is driven by the fan body and passes through the housing 1, the circuit board 5 and the air holes 121 on the button body 22 in turn, enters the second accommodating cavity 222 of the button assembly 2, and after mixing with the fragrance of the fragrance assembly 3, passes through the second through hole 2231, the fragrance outlet hole 225 and the gap 211 on the mounting plate 223 and spreads to the external environment of the switch module.

[0093] Optionally, the fan assembly 7 is electrically connected to the circuit board 5, and the working mode of the fan assembly 7 is associated with the type of the fragrance assembly 3. The relevant electronic components on the circuit board 5 can identify the type of the fragrance chip 33, and the control circuit on the circuit board 5 can control the fan assembly 7 to operate in a corresponding working mode according to the type of the fragrance chip 33. Among them, different working modes of the fan assembly 7 can correspond to different air output volumes, air output durations, etc., and the user can also set the working mode of the fan assembly 7 by himself through the vehicle's interactive module.

[0094] In a further embodiment, Figure 7 As shown, the knob assembly 4 includes a knob base 41 and a knob body 42. The knob base 41 is installed on the circuit board 5. The knob base 41 has a third accommodating cavity 411 for accommodating the button body 22. The knob body 42 is sleeved on the outer periphery of the knob base 41 and is rotatably connected to the knob base 41.

[0095] The knob base 41 is provided with a second limiting structure 412 , and the second limiting structure 412 is used for being matched and connected with the button body 22 .

[0096] like Figure 7 As shown, a radially outwardly protruding mounting boss 413 is provided on the bottom outer wall of the knob base 41, and the knob body 42 is axially mounted on the mounting boss 413, and there is a gap between the knob body 42 and the inner wall and the outer wall of the knob base 41, and the knob body 42 can rotate around its own central axis relative to the knob base 41.

[0097] The knob body 42 includes a first section 421 and a second section 422 connected to each other. The outer diameter of the first section 421 is larger than the outer diameter of the second section 422. The second section 422 is at least partially located in the first accommodating cavity 11. The end surface of the second section 422 connected to the first section 421 abuts against the outer flange 132 of the housing 1. The second section 422 is located outside the housing 1, and an uneven texture is provided on the outer wall of the second section 422, which increases the roughness of the outer wall of the second section 422, helps to increase the friction between the human hand and the knob body 42, and facilitates the user to easily turn the knob body 42.

[0098] The second limiting structure 412 is used to limit the axial movement of the button assembly 2 to prevent the button assembly 2 from axially moving when the user does not apply force to the button assembly 2 .

[0099] In a specific embodiment, Figure 4 As shown, a limiting hole 226 is formed on the side wall of the button body 22 , and the limiting hole 226 penetrates the side wall of the button body 22 along the radial direction of the button body 22 .

[0100] like Figure 7 and Figure 8 As shown, the knob base 41 is provided with a second mounting hole 414, and the second limiting structure 412 includes a locking tongue member 4121 and an elastic member 4122, and the opposite sides of the locking tongue member 4121 are connected to the hole wall of the second mounting hole 414 through the elastic member 4122, and the first end of the locking tongue member 4121 is used to partially extend into the limiting hole 226.

[0101] When the button assembly 2 moves along its own axis toward the side close to the circuit board 5 , the first end of the locking tongue piece 4121 is pressed down by the button body 22 , and the locking tongue piece 4121 rotates and can be separated from the limiting hole 226 .

[0102] For example, Fig. 9 As shown, there are two elastic members 4122 and the elastic members 4122 are torsion springs. A rotating shaft 4123 is provided on the locking tongue member 4121. The rotating shaft 4123 extends along the width direction of the locking tongue member 4121. The two elastic members 4122 are respectively arranged at both ends of the rotating shaft 4123, and the locking tongue member 4121 can rotate around the rotating shaft 4123.

[0103] In the initial state of the button assembly 2, a portion of the first end of the locking tongue piece 4121 is located in the limiting hole 226. When the button assembly 2 moves upward in the axial direction, the locking tongue piece 4121 abuts against the side wall of the knob base 41, and a portion of the first end of the locking tongue piece 4121 is still located in the limiting hole 226. The button assembly 2 cannot move further upward under the action of the locking tongue piece 4121, thereby preventing the button assembly 2 from being separated from the knob base 41. It can be understood that the initial state of the button assembly 2 is a state in which the pressing surface of the button assembly 2 is not subjected to external force.

[0104] Optionally, the side wall of the knob base 41 is further provided with a limiting step 415, such as Figure 7 and Figure 8 As shown, the limiting step 415 is located on the side of the rotating shaft 4123 away from the button body 22. Figure 7 and Fig.11 As shown, in the initial state of the button assembly 2, the locking tongue piece 4121 extends radially along the knob base 41, and the limiting step 415 abuts against the lower surface of the locking tongue piece 4121. The limiting step 415 is used to prevent the locking tongue piece 4121 from lifting up, thereby preventing the button assembly 2 from moving upward.

[0105] When it is necessary to remove the button assembly 2 from the knob base 41, it is only necessary to apply downward pressure to the button assembly 2. Fig.12 As shown, at this time, the first end of the locking tongue piece 4121 rotates downward under the drive of the button body 22 until it disengages from the limiting hole 226, thereby releasing the connection between the button assembly 2 and the knob base 41; then the knob assembly 4 is rotated to make the locking tongue piece 4121 offset from the limiting hole 226, thereby facilitating the upward removal of the button assembly 2.

[0106] Furthermore, if Fig.10 As shown, the inner wall of the knob body 42 is convexly provided with a third limiting structure 423, and the third limiting structure 423 is used to abut against the second end of the locking tongue member 4121 when the second end of the locking tongue member 4121 is lifted, so that the locking tongue member 4121 maintains a posture of being separated from the limiting hole 226. It can be understood that the first end and the second end of the locking tongue member 4121 are opposite ends in the extension direction of the locking tongue member 4121.

[0107] like Figure 7 and Fig.10 As shown, the third limiting structure 423 is block-shaped and extends radially along the knob body 42 , the end face of the third limiting structure 423 is spaced apart from the outer wall of the knob base 41 , and the height of the third limiting structure 423 is higher than the height of the rotating shaft 4123 of the second limiting structure 412 .

[0108] like Fig.11 As shown, in the initial state of the button assembly 2 , the third limiting structure 423 and the second limiting structure 412 are staggered in the circumferential direction to prevent the third limiting structure 423 from affecting the normal rotation of the second limiting structure 412 .

[0109] like Fig.13As shown, when downward pressure is applied to the button assembly 2 and the first end of the lock tongue piece 4121 is disengaged from the limiting hole 226, the knob body 42 is rotated to allow the third limiting structure 423 to rotate to below the second end of the lock tongue piece 4121. The rebound of the lock tongue piece 4121 can be limited by the abutment between the third limiting structure 423 and the second end of the lock tongue, thereby keeping the lock tongue piece 4121 disengaged from the limiting piece, making it convenient to remove the button assembly 2 from the knob base 41.

[0110] If the button assembly 2 is to be reinstalled into the knob base 41, insert the button assembly 2 into the knob base 41 so that the position of the limiting hole 226 corresponds to the position of the first end of the locking tongue piece 4121, and then rotate the knob body 42 again to disengage the third limiting structure 423 from the locking tongue piece 4121. The locking tongue piece 4121 rotates and rebounds under the action of the elastic piece 4122, and the second end of the locking tongue piece 4121 falls until it abuts against the limiting step 415. At this time, the first end portion of the locking tongue piece 4121 is located in the limiting hole 226, and the installation of the button assembly 2 is completed.

[0111] For example, Fig. 9 As shown, the first end of the locking tongue member 4121 is in a smooth arc shape so as to be disengaged from the limiting hole 226 as the button assembly 2 moves downward.

[0112] like Fig.10 As shown, the side walls on both sides of the third limiting structure 423 in the width direction are in the shape of an inclined surface, which facilitates guiding the second end of the locking tongue member 4121 to be lifted along the inclined surface to abut against the top of the third limiting structure 423.

[0113] like Fig.10 As shown, a groove 4231 is also provided on the top of the third limiting structure 423. When the second end of the locking tongue 4121 moves to cooperate with the groove 4231, it can give the user tactile feedback, so that the user can know that the locking tongue 4121 and the third limiting structure 423 are in place.
