Description

Technical Field

[0001] This application relates to the field of vehicle technology, and more particularly to an in-vehicle speaker assembly and a vehicle. Background Technology

[0002] Currently, very few car models on the market are equipped with retractable speakers, and the retractable speakers in related technologies are all vertically retractable structures. This vertical retraction method requires a large amount of space, which greatly limits its application in the compact interior space of a car.

[0003] On the other hand, the related liftable speaker structure is prone to damage when encountering foreign object impacts, resulting in high replacement costs. This is mainly due to the lack of an effective protection mechanism, with the impact force acting directly on the speaker body.

[0004] Therefore, there is a need to design an in-vehicle speaker assembly and vehicle that can solve the above-mentioned technical problems. Utility Model Content

[0005] This application provides a vehicle speaker assembly and vehicle that can protect the speaker and reduce maintenance costs.

[0006] According to a first aspect of the embodiments of this specification, a vehicle-mounted speaker assembly is provided, comprising a main housing, a speaker, and a drive assembly. The speaker is rotatably mounted on the main housing via a pivot shaft, and the drive assembly can drive the speaker to rotate and lift.

[0051] The technical solutions in the embodiments (or "implementations") of this application will be clearly and completely described herein with reference to the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

[0052] If the embodiments of this application contain terms relating to directional indications or positional relationships (such as up, down, left, right, front, back, inside, outside, top, bottom, center, vertical, horizontal, longitudinal, transverse, length, width, counterclockwise, clockwise, axial, radial, circumferential, etc.), such terms are only used to explain the relative positional relationships and movements between components in a specific posture (as shown in the attached figures); if the specific posture changes, the directional indications or positional relationships will also change accordingly. Furthermore, the terms "first" and "second" used in the embodiments of this application are only for descriptive convenience and should not be construed as indicating or implying relative importance.

[0053] The embodiments described in this specification will now be described in detail.

[0054] like Figures 1 to 3 As shown, the vehicle speaker includes a main housing 10, an air vent assembly 20, a speaker 30, and a drive assembly 40. The air vent assembly 20, the speaker 30, and the drive assembly 40 are all mounted on the main housing 10. The air vent assembly 20 is located below the speaker 30.

[0055] Please refer to the following at the same time Figures 4 to 6The main housing 10 is a one-piece molded structure, including a support plate 11 and an outer peripheral wall 12 surrounding the support plate 11. An upper receiving cavity 13 is provided at the upper part of the main housing 10. Specifically, the upper part of the support plate 11 and the outer peripheral wall 12 form the upper receiving cavity 13, and the top of the upper receiving cavity 13 opens upwards. The front side of the main housing 10 includes an annular air duct wall 14 disposed below the support plate 11. The rear side of the main housing 10 includes a main mounting portion 15 disposed below the support plate 11. In this application, the front side is the air outlet side, and the rear side is the side opposite to the air outlet side.

[0056] like Figure 4 and Figure 7 As shown, the main housing 10 is provided with a partition 16, which is located inside the upper receiving cavity 13. The partition 16 divides the upper receiving cavity 13 into a front cavity 131 and a rear cavity 132. The front cavity 131 is located directly above the air outlet channel 21 and is connected to the air outlet channel 21.

[0057] Please refer to the following at the same time Figures 8 to 10 The separator 16 includes a separator 161 and arms 162 located on both sides of the separator 161. The separator 161 includes a straight section 1611 and bent sections 1612 located at both ends of the straight section 1611 and protruding forward. The width of the straight section 1611 is greater than the width of the air outlet channel 21. The bent sections 1612 are located on the left and right sides of the air outlet channel 21, thereby ensuring that the air is not blocked by the separator 16 when it blows out of the air outlet channel 21, thus improving the air outlet efficiency.

[0058] The arm portion 162 extends rearward from the bent section 1612 to the rear side of the upper receiving cavity 13. Both the partition portion 161 and the arm portion 162 include a horizontal plate portion 1601 and a vertical plate portion 1602. The horizontal plate portion 1601 contacts and is fixed to the support plate 11. Mounting posts 1603 are provided on both the horizontal plate portion 1601 of the partition portion 161 and the horizontal plate portion 1601 of the arm portion 162, and screw holes 1604 are provided on the mounting posts 1603. Insert pieces 1605 are provided on the horizontal plate portion 1601 of the partition portion 161. The support plate 11 has insertion holes 111 for the insert pieces 1605 to pass through and mounting holes 112 for the mounting posts 1603 to pass through.

[0059] Thus, the arm 162 extends backward, enhancing the stability of the separator 16. The combined structure of the horizontal plate 1601 and the vertical plate 1602, together with the mounting post 1603 and the insert 1605, achieves precise positioning and fixation, improving the installation firmness and positioning accuracy of the separator 16 and ensuring the structural stability for long-term use.

[0060] like Figure 7 , Figure 9 , Figure 12 and Figure 14As shown, a sealing element 50 is provided on the upper edge of the partition 16, and the shape of the sealing element 50 is the same as the shape of the upper edge of the partition 161. The sealing element 50 includes a rear connecting part 51 that contacts the partition 16 and a front connecting part 52 that contacts the speaker. The bottom of the rear connecting part 51 is provided with a slot 511 to accommodate the upper edge of the partition 16; the front side of the front connecting part 52 is provided with a groove 521 that opens forward to increase the contact area between the speaker and the sealing element 50. The lower part of the speaker abuts against the front side of the front connecting part 52. By providing the sealing element 50, this application fixes the sealing element 50 to the upper edge of the partition 16 and abuts against the lower part of the raised speaker, which can effectively fill the gap between the partition 16 and the speaker, improve the sealing of the air outlet duct 21, effectively prevent air leakage from the air conditioner outlet, and ensure air outlet efficiency and effect.

[0061] In one embodiment, the seal 50 is made of rubber for easy replacement and maintenance. Furthermore, when the seal 50 comes into contact with the speaker, the elasticity of the rubber allows for an interference fit, increasing the tightness of the contact.

[0062] Please refer to the following at the same time Figure 11 The air outlet assembly 20 is disposed below the front side of the upper receiving cavity 13. The air outlet assembly 20 includes an air outlet channel 21 disposed within the main housing 10 and a blade assembly 22 disposed within the air outlet channel 21. The annular air duct wall 14 forms the air outlet channel 21, which communicates with the upper receiving cavity 13. The air outlet channel 21 includes an outlet channel 211 located above the blade assembly 22 and a main channel 212 located below the blade assembly 22.

[0063] Please refer to the following at the same time Figure 5 The main channel 212 is equipped with a channel partition wall 213, which divides the main channel 212 into a left air outlet channel 2121 and a right air outlet channel 2122. For example... Figure 15 As shown, the blade assembly 22 includes a left grille 221 and a right grille 222, and the interior assembly also includes two micro motors 223 that adjust the left grille 221 and the right grille 222 respectively. The two micro motors 223 are mounted on the main mounting part 15. The left grille 221 and the right grille 222 optimize the independence and precision of the air outlet distribution, effectively improve the flexibility of air outlet adjustment, and improve the air outlet experience in different areas.

[0064] The speaker is housed within the upper receiving cavity 13 to shield the air outlet duct 21. The speaker can be raised or lowered to open or close the air outlet duct 21.

[0065] like Figure 4As shown, according to one embodiment of this application, the speaker is rotatably mounted on the main housing 10 via a pivot 313. The pivot 313 is located away from the front side (i.e., the air outlet side) of the main housing 10, and the air outlet assembly 20 is located on the lower part of the main housing 10 away from the pivot 313. When raised, the speaker rotates clockwise from front to back around the pivot 313; when lowered, the speaker rotates counterclockwise from back to front around the pivot 313. A pair of downwardly protruding connecting posts 314 are provided on both sides of the lower part of the speaker.

[0066] When the outlet channel 211 is closed, the speaker completely blocks the opening at the top of the upper receiving cavity 13, and the speaker forms a smooth curved surface with the upper surface of the main housing 10. Figure 16 As shown, when the air outlet assembly 20 is working, the speaker 30 and the main housing 10 form an air outlet 210 that communicates with the air outlet channel 21.

[0067] Please refer to the following at the same time Figure 17 The speaker 30 includes a speaker housing 31, a speaker element 32 disposed within the speaker housing 31, and a speaker cover 33 located above the speaker housing 31. The speaker cover 33 is located within the top opening of the upper receiving cavity 13, and the shape of the speaker cover 33 is the same as the shape of the top opening; the width of the speaker cover 33 gradually decreases from front to back.

[0068] Please refer to the following at the same time Figure 11 The speaker 30 includes an air guide portion 311 formed near the air outlet assembly 20, with the main body of the speaker located behind the air guide portion 311. The air guide portion 311 is a curved surface that gradually slopes forward from bottom to top, forming an air guide surface that guides the airflow in the lower air outlet channel 21 to the air outlet 210. The air guide surface forms the rear sidewall of the air outlet channel 21.

[0069] Please refer to the following at the same time Figure 17 and Figure 18 The air guide section 311 includes a left air guide slot 3111 and a right air guide slot 3112 corresponding to the left air guide slot 221 and the right air guide slot 222, respectively. A protrusion 3113 is provided between the left air guide slot 3111 and the right air guide slot 3112. Two micro motors 223 are arranged near the rear side of the air guide section 311 and are located on both sides of the drive motor 41. The two micro motors 223 act on the left air guide 221 and the right air guide 222 respectively, ensuring airflow while allowing for flexible adjustment on both sides.

[0070] Please refer to the reference again. Figures 11-12As shown, the speaker has a receiving cavity 312 to accommodate the partition 16. When the speaker is lowered, the partition 16 is located inside the receiving cavity 312. When the speaker is raised, the speaker is located above the partition 16, and the lower edge of the air guide 311 coincides with the upper edge of the partition 16. The speaker and the partition 16 together form a closed air guide structure to prevent airflow leakage from the rear. The speaker, the partition 16, and the main housing 10 together form the air outlet 210 of the air outlet channel 21. The air outlet 210 is formed when the speaker 30 is raised, and it is occupied when the speaker 30 is lowered.

[0071] The side of the air outlet 210 closest to the speaker has a closed air guide structure, while the side of the air outlet 210 furthest from the speaker, i.e., the air outlet side, is connected to the outside. Furthermore, after the speaker is raised, its lower part contacts the sealing member 50, which seals and isolates the air outlet 210 from the rear cavity 132. The sealing member 50 is positioned between the speaker and the partition 16. The speaker, partition 16, and sealing member 50 together seal the rear side of the air outlet channel 21, further preventing air leakage from the outlet between the speaker and the partition 16.

[0072] Because the blade assembly 22 is located below the support plate 11, the main housing 10 covers the blade assembly 22 from all sides. When the outlet channel 211 is open, the blade assembly 22 protrudes from all sides of the speaker, completely covering the blade assembly 22 from above. Therefore, when the speaker is raised and the air outlet assembly 20 is working, passengers cannot see the blade assembly 22 from any angle, and the air outlet assembly 20 is completely hidden.

[0073] Please refer to the following at the same time Figure 13 The speaker 30 has a cover plate 310 and an air guide 311 located below the cover plate 310 and facing the air outlet 210. The cover plate 310 protrudes upward from the main housing 10. A dry and wet separation area 315 is provided between the air guide 311 and the cover plate 310 to prevent condensation from forming at the edge of the cover plate 310.

[0074] Specifically, the dry and wet separation zone 315 includes a vertically connected partition surface 3151 and a horizontally connected windproof surface 3152; the vertical partition surface 3151 bends upward from the air guide section 311, and the horizontally connected windproof surface 3152 protrudes from the vertical partition surface 3151 toward the air outlet 210.

[0075] The cover plate 310 has an edge including a top surface 3101 and a side surface 3102 extending downward from the top surface 3101. The side surface 3102 connects to the transverse windbreak surface 3152 and extends from the transverse windbreak surface 3152 in a direction away from the air outlet 210. The edge of the cover plate 310 is located within the outer contour of the transverse windbreak surface 3152, which provides shelter for the edge of the cover plate 310 from below. The lowest point of the transverse windbreak surface 3152 is located above the air guide portion 311; the side of the transverse windbreak surface 3152 near the air outlet 210 is lower than the side away from the air outlet 210.

[0076] The vertical dividing surface 3151 offsets the cover plate 310 upwards from the air outlet direction, while the horizontal wind-blocking surface 3152 further shields the edges of the cover plate 310, preventing cold air from directly contacting it. By setting up the dry and wet separation zone 315, cold air cannot be blown directly onto the cover plate 310, so no condensation will form on the visible cover plate 310, improving the user experience.

[0077] like Figure 18 As shown, the drive assembly 40 is assembled on the main mounting section 15 and is used to drive the speaker to rise and fall, thereby opening or closing the outlet channel 211. The drive assembly 40 includes a drive motor 41 and a linkage assembly 42. Two micro motors 223 are disposed near the rear side of the air guide section 311 and are located on both sides of the drive motor 41.

[0078] like Figures 19 to 22 As shown, the linkage assembly 42 is disposed between the drive motor 41 and the speaker, including a motor drive rod 421 connected to the drive motor 41, a transmission rod 422 connected to the motor drive rod 421 and rotating synchronously, and a lifting linkage 423 disposed between the transmission rod 422 and the speaker.

[0079] The motor drive rod 421 includes a main rod 4211 and a connecting rod 4212 located near the middle of the main rod 4211 and perpendicular to the main rod 4211. The connecting rod 4212 is connected to the drive motor 41, and the main rod 4211 is parallel to the motor shaft 411. Both ends of the main rod 4211 are connected to a transmission rod 422.

[0080] The transmission rod 422 includes a rotating part 4221 connected to the main rod 4211 and a main body part 4222 perpendicular to the main rod 4211. A guide rail 4223 is formed on the side of the main body part 4222, and one end of the lifting link 423 slides along the guide rail 4223. The other end of the lifting link 423 is fixedly connected to the connecting column 314. The guide rail 4223 ensures that the sliding of the lifting link 423 retains only a single translational degree of freedom along the direction of the guide rail 4223, effectively suppressing swaying in other directions and ensuring high repeatability of the speaker's lifting action.

[0081] The drive assembly 40 can drive the speaker to rotate and rise, thereby controlling the connection or disconnection of the air outlet duct 21 with the outside world. When the speaker rises or falls, the drive motor 41 receives the vehicle domain control unit (ZCU) signal and starts working. The motor shaft 411 drives the motor drive rod 421 to rotate, and the transmission rod 422 rotates accordingly; the transmission rod 422 drives the lifting linkage 423 to rise or fall, and the lifting linkage 423 drives the speaker to rise or fall.

[0082] Compared to other mechanisms such as gears, linkage mechanisms offer higher reliability and stability, ensuring normal operation of the speaker both before and after it is raised, thus meeting various user scenarios. The physical connection between the shaft and the linkage also reduces the likelihood of abnormal noise.

[0083] Please refer to the reference again. Figure 23-24 As shown, according to one embodiment of this application, a clutch assembly 60 is provided on the drive motor 41. The clutch assembly 60 includes a clutch gear 61 fixed on the motor shaft 411, a clutch sleeve 62 sleeved on the motor shaft 411 and meshing with the clutch gear 61, and a spring 63 disposed between the motor shaft 411 and the clutch sleeve 62. The clutch sleeve 62 is connected to the motor drive rod 421.

[0084] Specifically, the clutch gear 61 is fixed to one end of the motor shaft 411, and the clutch sleeve 62 is disposed inside the clutch gear 61. The clutch sleeve 62 includes a gear portion 621 that meshes with the clutch gear 61 and a sleeve portion 622. The outer side of the sleeve portion 622 is connected to the motor drive rod 421, and the spring 63 is disposed inside the sleeve portion 622 and sleeved on the outside of the motor shaft 411. The motor shaft 411 is provided with a stepped portion 412, and the two ends of the spring 63 abut against the stepped portion 412 and the sleeve portion 622, respectively.

[0085] When the speaker 30 is subjected to excessive force, i.e., when the external force exceeds the spring force, the clutch gear 61 and clutch sleeve 62 can disengage. The speaker 30 can then move freely to protect the connecting rod assembly 42. After the clutch gear 61 and clutch sleeve 62 disengage, they are recalibrated via software to return to their original positions and restore normal lifting and lowering functions.

[0086] By installing a clutch assembly 60 on the drive motor 41, it can buffer and protect against abnormal situations such as collisions with foreign objects, effectively improving safety and reliability and reducing maintenance costs.

[0087] like Figure 3 and Figure 4As shown, according to one embodiment of this application, a midrange speaker 70 is also included. The midrange speaker 70 is integrated into the main housing 10 and located behind the speaker 30. A midrange speaker cover 17 is integrally formed on the main housing 10; the upper surface of the midrange speaker cover 17 is flush with the upper surface of the main housing 10. The speaker 30, the midrange speaker 70, and the upper surface of the main housing 10 are all located within the same smooth surface, effectively improving the overall coordination and quality of the interior components, and enhancing the visual and user experience of the driving environment. The width of the midrange speaker cover 17 gradually decreases from front to back, and its width change trend is consistent with the width change trend of the speaker cover 33, thus ensuring a smooth transition at the junction of the two.

[0088] In this application, both the air outlet assembly 20 and the speaker are mounted on the main housing 10, with the speaker also serving as the air outlet cover. The concealed air outlet and the retractable speaker are integrated through the main housing 10, which can significantly reduce weight and cost.

[0089] All air outlet components 20 are located within the main housing 10 and are completely concealed by the speaker when not in operation. When the air outlet components 20 are in operation, only the speaker rises, and the blade assembly 22 remains hidden, achieving a fully concealed structure. The air outlet 210 does not occupy separate panel space, saving space while maintaining a stylish and simple overall design.
