[0006] Furthermore, the connecting assembly includes a first connecting seat and a second connecting seat connected by a connecting rod; the connecting rod is arranged along the lifting direction of the speaker mounting base, the first connecting seat is screwed to the lead screw, and the second connecting seat is connected to the speaker mounting base.

[0007] Furthermore, the housing is provided with a limiting part; the connecting rod is arranged to pass through the limiting part, and when the speaker mounting base is in the raised state, the limiting part forms a limiting engagement with the first connecting base, and when the speaker mounting base is in the lowered state, the limiting part forms a limiting engagement with the second connecting base.

[0008] Furthermore, a plurality of connecting rods are connected between the first connecting seat and the second connecting seat; and / or, a mounting base is provided in the housing, the lead screw is rotatably mounted on the mounting base, and the limiting part is provided on the mounting base.

[0010] Furthermore, the housing includes a first housing, a second housing, and a cover plate; the first housing and the second housing are fastened together, forming the inner cavity between the first housing and the second housing; the cover plate is used to cover the top of the inner cavity, and the cover plate is provided with an opening to avoid the speaker mounting base.

[0011] Furthermore, a guide assembly is provided between the speaker mounting base and the vehicle body component, the guide assembly being adapted to guide the lifting and lowering of the speaker mounting base; and / or, a decorative element is provided on the speaker mounting base, and a speaker arrangement space is formed between the decorative element and the speaker mounting base.

[0012] Furthermore, the gear transmission assembly includes a drive gear disposed on the drive end of the drive unit and a driven gear disposed on the lead screw, wherein the drive gear and the driven gear mesh; and / or, the body component is an instrument panel or a shelf.

[0013] Compared with related technologies, this application has the following advantages: (1) The lifting device described in this application forms a screw-nut transmission form by screwing together a screw and a connecting component. The screw-nut transmission form can be used to improve the load-bearing capacity of the transmission mechanism and the positioning accuracy of the speaker mounting seat during the lifting process, thereby improving the lifting stability and lifting control accuracy of the vehicle speaker. At the same time, by using a gear transmission component, different transmission ratios can be achieved under the cooperation of the gear transmission form to flexibly match different speed requirements, so that the lifting speed of the speaker mounting seat has more options, thereby improving the lifting effect of the vehicle speaker, which can help improve the overall interior quality of the vehicle.

[0014] (2) By setting up a housing, it is convenient to arrange and install the speaker mounting base, drive unit and transmission mechanism, thereby improving the compactness and structural stability of the lifting device.

[0015] (3) The connecting component includes a connecting rod, a first connecting seat and a second connecting seat. The connecting rod is arranged along the lifting direction of the speaker mounting seat. The first connecting seat is screwed to the lead screw, and the second connecting seat is connected to the speaker mounting seat. This not only facilitates the screw connection between the connecting component and the lead screw, as well as the connection between the connecting component and the speaker mounting seat, but also simplifies the structure and controls the manufacturing cost.

[0016] (4) By setting a limiting part in the housing, when the speaker mounting base is in the raised state, the limiting part forms a limiting engagement with the first connecting base, and when the speaker mounting base is in the lowered state, the limiting part forms a limiting engagement with the second connecting base. The lifting limit position can be adjusted by controlling the length of the connecting rod, that is, the distance between the first connecting base and the second connecting base, which can help meet the needs of different lifting distances of the vehicle speaker.

[0017] (5) By connecting multiple connecting rods between the first connecting seat and the second connecting seat, the connecting rod assembly can be constrained by each connecting rod to prevent the connecting rod assembly from rotating around the lead screw axially, thus ensuring its lifting and lowering stability and guaranteeing the lifting and lowering stability of the vehicle speaker. At the same time, the installation base facilitates the arrangement and installation of the lead screw and the limiting part, improving the structural compactness of the lifting device.

[0018] (6) By providing a groove on the second connector and a connecting plate on the speaker mounting base, with the connecting plate inserted into the groove, it is not only convenient to connect the speaker mounting base and the connecting assembly together, but also to improve the convenience and reliability of the connection. Furthermore, the second connector and the speaker mounting base are detachably connected by fasteners, which enables convenient assembly and disassembly between the speaker mounting base and the connecting assembly.

[0019] (7) The housing mainly includes a first housing, a second housing and a cover plate. The first housing and the second housing are fastened together to form an inner cavity, and the cover plate covers the top of the inner cavity and the opening. This not only simplifies the assembly method and reduces the difficulty of installing components such as the speaker mounting base, drive unit, transmission mechanism and guide assembly in the cavity, but also helps to ensure the normal lifting and lowering of the speaker mounting base.

[0020] (8) By setting a guide component, the movement direction of the speaker mounting base can be guided, thereby improving the stability of the speaker mounting base during the lifting process relative to the vehicle body parts. At the same time, setting a decorative part on the speaker mounting base can meet the appearance requirements of matching the shape of the vehicle body parts, and a speaker placement space is formed between the decorative part and the speaker mounting base. The speaker placement space can be used to realize the hidden placement of the vehicle speakers, which can further enhance the appearance of the lifting device.

[0021] (9) The gear transmission assembly includes meshing drive gears and driven gears, which not only has a simple structure, mature products, and low cost, but also facilitates the realization of different transmission ratios between the drive unit and the lead screw to flexibly match different speed requirements. This allows for more choices in the lifting speed of the speaker mount, thereby improving the lifting effect of the vehicle speaker. At the same time, by using the vehicle body part as a dashboard or shelf, the lifting device can be arranged inside the vehicle, with only the speaker mount lifting the vehicle speaker. This can meet different styling requirements and enhance the interior's refinement.

[0022] This application also proposes a vehicle in which a lifting device as described above is provided.

[0023] The vehicle described in this application is equipped with the aforementioned lifting device, which can improve the lifting effect of the vehicle speakers, thereby enhancing the overall interior quality of the vehicle. Attached Figure Description

[0028] Furthermore, in the description of this application, unless otherwise expressly defined, the terms "installation," "connection," "joining," and "connector" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application in light of the specific circumstances.

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0030] The present application will now be described in detail through exemplary embodiments. However, it should be understood that, without further description, elements, structures, and features in one embodiment may be advantageously incorporated into other embodiments.

[0031] An embodiment of the first aspect of this application provides a lifting device that improves the smoothness of raising and lowering a vehicle speaker, thereby improving the overall interior quality of the vehicle.

[0032] In related technologies, with the development of vehicle intelligence, more and more vehicles are now equipped with high-quality audio systems. Among them, the placement of vehicle speakers, as an important component of the audio system, is becoming more and more diverse.

[0033] Vehicle speakers are typically fixed inside the vehicle, and their housings are usually perforated, resulting in a monotonous design that accumulates dust over time, providing a generally unpleasant experience for passengers. To address these issues, more and more speakers are being installed with adjustable lift mechanisms within the vehicle. However, traditional lift mechanisms suffer from insufficient load-bearing capacity and stability, affecting the speaker's lifting performance and hindering the overall improvement of the vehicle's interior quality.

[0034] In view of this, in order to overcome the shortcomings of the related technology, the lifting device in this embodiment combines... Figures 1 to 9 As shown, in terms of overall design, it is mounted on the vehicle body component 9 and is adapted to drive the vehicle speaker to rise and fall. The lifting device includes a drive unit 2 mounted on the vehicle body component 9, a speaker mounting base 3 that can rise and fall relative to the vehicle body component 9, and a transmission mechanism disposed between the drive unit 2 and the speaker mounting base 3.

[0035] The transmission mechanism includes a lead screw 4 rotatably mounted on the body component 9, a connecting assembly 5 screwed to the lead screw 4, and a gear transmission assembly 6 located between the lead screw 4 and the drive unit 2, and the speaker mounting base 3 is connected to the connecting assembly 5.

[0036] Therefore, by screwing the lead screw 4 and connecting component 5 together to form a lead screw 4 nut transmission, the load-bearing capacity of the transmission mechanism and the positioning accuracy of the speaker mounting bracket 3 during the lifting process can be improved. This, in turn, enhances the lifting stability and lifting control accuracy of the vehicle speaker. At the same time, by using gear transmission component 6, different transmission ratios can be achieved under the gear transmission to flexibly match different speed requirements, giving the speaker mounting bracket 3 more options for lifting speed. This improves the lifting effect of the vehicle speaker and thus enhances the overall interior quality of the vehicle.

[0037] Based on the above general introduction, specifically, the speaker mounting base 3 of this embodiment is equipped with a vehicle speaker. At the same time, the lead screw 4 and the connecting component 5 are screwed together, which means that the two are connected by threaded transmission to form a transmission form similar to the lead screw 4 and nut transmission, converting the rotational motion into the linear motion of the connecting component 5, that is, the connecting component 5 drives the speaker mounting base 3 to rise and fall.

[0038] Furthermore, continue to combine Figures 4 to 6 As shown, in some of the exemplary embodiments, the drive unit 2 of this embodiment preferably employs a servo motor to provide higher precision control and better dynamic response performance.

[0039] Continue to combine Figures 1 to 4 As shown, in some exemplary embodiments, the lifting device of this embodiment also includes a housing 1 disposed on the vehicle body component 9. Specifically, the speaker mounting base 3 is lifted relative to the housing 1, and the drive unit 2 and the transmission mechanism are housed in the inner cavity of the housing 1.

[0040] By setting up the housing 1, the arrangement and installation of the speaker mounting base 3, the drive unit 2 and the transmission mechanism can be facilitated, thereby improving the compactness and structural stability of the lifting device.

[0041] It should be noted that the direction-related descriptions in this embodiment are merely illustrative examples. In actual implementation, the direction descriptions in this embodiment vary depending on the orientation of the housing 1; that is, each direction in this embodiment refers to a relative coordinate system with the housing 1 as the reference. Furthermore, the lifting direction of the speaker mounting base 3 in this embodiment is the height direction of the housing 1.

[0042] Continue to combine Figures 4 to 7 As shown, in some exemplary embodiments, the connecting assembly 5 includes a first connecting seat 502 and a second connecting seat 503 connected by a connecting rod 501. Specifically, the connecting rod 501 is arranged along the lifting direction of the speaker mounting base 3, the first connecting seat 502 is screwed to the lead screw 4, and the second connecting seat 503 is connected to the speaker mounting base 3.

[0043] The connecting component 5 includes a connecting rod 501, a first connecting seat 502, and a second connecting seat 503. The connecting rod 501 is arranged along the lifting direction of the speaker mounting base 3. The first connecting seat 502 is screwed to the lead screw 4, and the second connecting seat 503 is connected to the speaker mounting base 3. This not only facilitates the screwed connection between the connecting component 5 and the lead screw 4, as well as the connection between the connecting component 5 and the speaker mounting base 3, but also simplifies the structure and controls the manufacturing cost.

[0044] Furthermore, continue to combine Figures 4 to 7 As shown, in some exemplary embodiments, the housing 1 is provided with a limiting part 1004. The connecting rod 501 is disposed across the limiting part 1004, and when the speaker mounting base 3 is in the raised state, the limiting part 1004 forms a limiting engagement with the first connecting base 502, and when the speaker mounting base 3 is in the lowered state, the limiting part 1004 forms a limiting engagement with the second connecting base 503.

[0045] By providing a limiting part 1004 in the housing 1, and when the speaker mounting base 3 is in the raised state, the limiting part 1004 forms a limiting engagement with the first connecting seat 502, and when the speaker mounting base 3 is in the lowered state, the limiting part 1004 forms a limiting engagement with the second connecting seat 503. The lifting limit position can be adjusted by controlling the length of the connecting rod 501, that is, the distance between the first connecting seat 502 and the second connecting seat 503, thereby meeting the needs of different lifting distances of vehicle speakers.

[0046] The aforementioned connecting rod 501 is arranged to pass through the limiting part 1004, meaning that the connecting rod 501 passes through the limiting part 1004 in the lifting direction. At the same time, the limiting part 1004 can cooperate with the first connecting seat 502 to limit the highest position of the speaker mounting base 3 when it rises, and can also cooperate with the second connecting seat 503 to limit the lowest position of the speaker mounting base 3 when it falls.

[0047] Furthermore, in some exemplary embodiments, a plurality of connecting rods 501 are connected between the first connecting seat 502 and the second connecting seat 503. This arrangement allows the connecting rod 501 assembly to be constrained by each connecting rod 501, preventing axial rotation of the connecting rod 501 assembly around the lead screw 4 and ensuring smooth lifting and lowering, thereby guaranteeing the smooth lifting and lowering of the vehicle speaker.

[0048] In specific implementation, the aforementioned connecting rod 501 can be two or three, as long as it can ensure that the connecting rod 501 assembly can rise and fall normally without rotating around the axial direction of the lead screw 4. The aforementioned first connecting seat 502 and second connecting seat 503 can both be designed in a disc shape in overall appearance. If necessary, the first connecting seat 502 or the second connecting seat 503 in this embodiment can also be designed to reduce weight. For example, an arc-shaped material removal part can be provided on the first connecting seat 502, and the arc-shaped material removal part can be two parts arranged symmetrically along the radial direction of the first connecting seat 502.

[0049] At the same time, continue to combine Figures 4 to 7 As shown, in some exemplary embodiments, the housing 1 is provided with a mounting base 10, the lead screw 4 is rotatably mounted on the mounting base 10, and the limiting part 1004 is provided on the mounting base 10. The main advantage of this arrangement is that it facilitates the arrangement and installation of the lead screw 4 and the limiting part 1004, thereby improving the structural compactness of the lifting device.

[0050] Continue to combine Figures 4 to 7 As shown, in some of the exemplary embodiments, the second connector 503 is provided with a groove 5031, and the speaker mounting base 3 is provided with a connecting plate 301, which is inserted into the groove 5031.

[0051] Here, by providing a groove 5031 on the second connecting seat 503 and a connecting plate 301 on the speaker mounting seat 3, and inserting the connecting plate 301 into the groove 5031, it is not only convenient to connect the speaker mounting seat 3 and the connecting component 5 together, but also to improve the convenience and reliability of the connection.

[0052] Furthermore, in some exemplary embodiments, the second connector 503 and the speaker mounting base 3 are detachably connected by fasteners. This facilitates easy assembly and disassembly between the speaker mounting base 3 and the connector assembly 5.

[0053] In specific implementation, the connecting plate 301 is provided with a first connecting hole, and the second connecting seat 503 is provided with a second connecting hole 5032 corresponding to the groove 5031. The connecting plate 301 is inserted into the groove 5031, and the fasteners are inserted into the first connecting hole and the second connecting hole 5032 to form a connection between the connecting plate 301 and the speaker mounting seat 3, while taking into account both the convenience of disassembly and assembly and the reliability of the connection.

[0054] In addition, continue to combine Figures 1 to 4As shown, in some exemplary embodiments, the housing 1 includes a first housing 101, a second housing 102, and a cover plate 103. The first housing 101 and the second housing 102 are fastened together, forming an inner cavity between them. The cover plate 103 covers the top of the inner cavity and has an opening 1030 to allow passage for the speaker mounting base 3.

[0055] It can be understood that the housing 1 mainly includes a first housing 101, a second housing 102 and a cover plate 103. The first housing 101 and the second housing 102 are fastened together to form an inner cavity, while the cover plate 103 covers the top of the inner cavity and covers the opening 1030. This not only simplifies the assembly method and reduces the difficulty of installing components such as the speaker mounting base 3, the drive unit 2, the transmission mechanism and the guide assembly in the cavity, but also helps to ensure the normal lifting and lowering of the speaker mounting base 3.

[0056] In addition, continue to combine Figure 4 and Figure 5 As shown, in some exemplary embodiments, a guide assembly is provided between the speaker mount 3 and the body component 9, the guide assembly being adapted to guide the raising and lowering of the speaker mount 3. Thus, the guide assembly can be used to guide the direction of movement of the speaker mount 3, thereby improving the stability of the speaker mount 3 during the raising and lowering process relative to the body component 9.

[0057] In some exemplary embodiments, the guide assembly of this embodiment includes a plurality of guide rods 7 disposed on the first housing 101 and located in the inner cavity, and a plurality of sliding seats 302 are provided on the speaker mounting base 3, each sliding seat 302 being sleeved on the guide rod 7 in a corresponding manner, and each sliding seat 302 slidingly engaging with the corresponding guide rod 7.

[0058] This further enhances the stability and reliability of the speaker mounting bracket 3 during its lifting and lowering process. Furthermore, the number of guide rods 7 can be set to two or three, depending on the guiding requirements.

[0059] It is understandable that the guide rod 7 can form a slide rail structure inside the cavity. The slide rail structure is used to allow the sliding seat 302 to slide, so as to guide the movement direction of the speaker mounting seat 3 through the guide rod 7, thereby improving the stability of the speaker mounting seat 3 relative to the housing 1 during movement.

[0060] In some exemplary embodiments, the guide rod 7 is disposed within the inner cavity along the height direction of the housing 1, and both ends of the guide rod 7 are connected to the side wall and top wall 1013 of the first housing 101, respectively. The guide rod 7 can be fixed by means of threaded fasteners such as bolts, or by snap-fit ​​connection with the first housing 101, etc., without specific limitations, as long as the installation stability of the guide rod 7 is ensured.

[0061] Continue to combine Figure 8 and Figure 9 As shown, in some exemplary embodiments, the speaker mounting base 3 is provided with a decorative element 8, and a speaker arrangement space Q is formed between the decorative element 8 and the speaker mounting base 3, and the vehicle speaker is located in the speaker arrangement space Q.

[0062] By setting the decorative piece 8 on the speaker mounting base 3, the appearance requirement of matching the shape of the body part 9 can be met. Furthermore, a speaker arrangement space Q is formed between the decorative piece 8 and the speaker mounting base 3. The speaker arrangement space Q can be used to achieve a hidden arrangement of the vehicle speaker, which can further enhance the appearance and refinement of the lifting device.

[0063] Furthermore, continue to combine Figure 8 and Figure 9 As shown, in some exemplary embodiments, the trim piece 8 includes a first trim panel 801, a second trim panel 802, and a trim panel connecting plate 803. The first trim panel 801 is connected to the speaker mounting base 3 to form the aforementioned speaker arrangement space Q. The first trim panel 801 has a sound outlet 804 to ensure the sound output effect of the vehicle speaker. The first trim panel 801 can also cover the vehicle speaker, preventing it from being exposed and reducing the risk of dust entering the speaker area when the trim piece 8 is in the open position.

[0064] The second decorative panel 802 is located on the side of the first decorative panel 801 away from the speaker mounting base 3, and the second decorative panel 802 is opposite to and spaced apart from the first decorative panel 801, and the second decorative panel 802 is used to cover the opening 1030. It can be understood that when the decorative piece 8 is in the closed state, the second decorative panel 802 can cover the opening 1030 and prevent dust from entering the speaker arrangement space Q through the opening 1030.

[0065] Continue to combine Figure 8 and Figure 9 As shown, in some exemplary embodiments, the trim panel connecting plate 803 is connected between the first trim panel 801 and the second trim panel 802, and the trim panel connecting plate 803 is arranged along the height direction of the housing 1. The trim panel connecting plate 803 can connect and support the first trim panel 801 and the second trim panel 802 to form a clearance space between the first trim panel 801 and the second trim panel 802, so as to ensure the sound output effect of the vehicle speaker at the first trim panel 801.

[0066] Continue to combine Figure 8 and Figure 9As shown, in some exemplary embodiments, the trim panel connecting plate 803 is constructed as an arc-shaped plate, and the arc-shaped plate is connected to the first trim panel 801 and the second trim panel 802 at both ends in the direction of its own axis, respectively. The opening 1030 of the arc-shaped plate is open towards the sound outlet 804 to concentrate the sound and improve the sound output effect of the vehicle speaker.

[0067] In some exemplary embodiments, the projection of the opening 1030 falls within the projection of the second trim panel 802 in the projection direction of the lifting direction. That is, when the trim panel 8 is in the closed state, the second trim panel 802 can completely cover the opening 1030 to fully block the opening 1030 and ensure the blocking effect of the trim panel 8 on the opening 1030.

[0068] The shape of the second decorative panel 802 is adapted to the shape of the opening 1030. When the opening 1030 is circular, the second decorative panel 802 is also constructed as a circular panel so that the second decorative panel 802 corresponds fully to the opening 1030.

[0069] In addition, continue to combine Figures 4 to 6 As shown, in some exemplary embodiments, the gear transmission assembly 6 includes a drive gear 601 disposed on the drive end of the drive unit 2 and a driven gear 602 disposed on the lead screw 4, wherein the drive gear 601 and the driven gear 602 mesh.

[0070] It can be understood that the gear transmission assembly 6, which includes a meshing drive gear 601 and a driven gear 602, is not only simple in structure, mature in product and low in cost, but also facilitates the realization of different transmission ratios between the drive unit 2 and the lead screw 4, so as to flexibly match different speed requirements, and make the speaker mounting bracket 3 have more choices in lifting speed, thereby improving the lifting effect of the vehicle speaker.

[0071] In specific implementation, the aforementioned lead screw 4 is rotatably mounted on the mounting platform 1005 of the mounting base 10, and includes a threaded section 402 located above the mounting platform 1005 and a mounting section 401 located below the mounting platform 1005. The driven gear 602 is mounted on the mounting section 401, and the connecting assembly 5 is threadedly engaged with the threaded section 402.

[0072] Furthermore, in some exemplary embodiments, the body component 9 is a dashboard or shelf. This allows the lifting device to be positioned inside the vehicle, with only the speaker mount 3 lifting and lowering along with the vehicle speaker, facilitating the fulfillment of different styling requirements and enhancing the interior's refined feel.

[0073] In specific implementations, in some exemplary embodiments, the housing 1 of this embodiment includes: a first housing 101, a second housing 102 and a cover. The first housing 101 and the second housing 102 are fastened together to form a cavity. The cover plate 103 covers the first housing 101 and the second housing 102 and forms an opening 1030.

[0074] The housing 1 is installed as follows: after the first housing 101 and the second housing 102 are fastened together to form a cavity, a cover plate 103 is further used to cover the first housing 101 and the second housing 102 to obtain the assembled housing 1.
