Description

Technical Field

[0001] This utility model relates to a car speaker, and more specifically, to a continuously rotating lifting speaker motion mechanism and a car lifting speaker. Background Technology

[0002] As an in-car audio-visual device that combines auditory enjoyment with visual aesthetics, the car rotating and lifting speaker has become a preferred configuration for fashion-conscious car owners due to its dynamic mechanical movements and diverse atmosphere-creating capabilities. Its core purpose is not only to play audio to satisfy auditory needs, but also to echo the interior style of the car through the mechanical rhythm of rotation and lifting, light effects and other visual presentations, thereby enhancing the sense of technology and atmosphere of the car space and achieving a dual upgrade of auditory and visual experience.

[0003] The basic structure of existing automotive rotating and lifting loudspeakers is relatively mature, mainly consisting of four core units: First, the drive unit, which generally uses a motor as the power source, coupled with a gear transmission mechanism to achieve power output; second, the rotating and lifting transmission unit, including a sleeve, connecting seat, rotating large gear, and rotating lifting fixed bracket, which converts the rotational power of the drive unit into linear lifting motion through threaded engagement, track and protrusion engagement, etc.; third, the decorative unit, mainly composed of decorative rings, light diffusion rings, light guides, decorative covers, etc.; and fourth, the speaker unit, as the core of audio output, whose installation position is adapted to the decorative unit and transmission unit to ensure that the sound output direction is coordinated with the visual presentation. Its working principle is as follows: the motor starts after receiving a control signal, and transmits power to the rotating and lifting transmission unit through gear meshing. Utilizing the helical motion characteristics of the threaded connection, the transmission unit drives the decorative unit and the speaker (or sound output end) to synchronously complete the rotation and lifting actions; through the luminous decorative unit, the light moves rhythmically with the audio melody, further enhancing the atmosphere. For details on the specific structure and working principle, please refer to the "Compact Car Rotary Lifting Speaker" disclosed in Chinese Patent Publication No. CN212796725U.

[0004] However, the existing mechanical operation mode of automotive rotary lift speakers has significant limitations: it can only achieve a simple "rotation + lifting," meaning that the upward movement is completed simultaneously when rotating forward, and the downward movement is completed simultaneously when rotating backward. Throughout the entire normal driving process, the rotary lift speaker remains stationary, producing no rotational rhythm, and completely fails to meet the requirement of "continuous rotational rhythm" in driving scenarios. This limited performance results in a monotonous visual presentation, making it difficult to create a dynamic and coherent in-car atmosphere. Based on these problems, it is necessary to improve the existing automotive rotary lift speaker. Summary of the Invention

[0005] 1. Technical problem to be solved by the utility model

[0006] The purpose of this invention is to overcome the aforementioned shortcomings of existing automotive rotating and lifting speakers, and to provide a continuously rotating lifting speaker movement mechanism and automotive lifting speaker. The technical solution of this invention involves replacing the inner cylinder on the original base with a rotatable structure, and using a rotational damper to provide rotational resistance to the inner cylinder. When the drive assembly rotates the lifting sleeve, the spiral structure between the lifting sleeve and the inner cylinder enables simultaneous rotation and lifting. When the lifting sleeve reaches its stop position, it can drive the inner cylinder to overcome the rotational resistance and rotate together, thus achieving continuous rotational movement of the lifting sleeve and providing a continuous rotational rhythm effect. Furthermore, the combination of the inner cylinder and the rotational damper results in a simple and compact structure, easy assembly and manufacturing, and good movement stability.

[0027] 3. Beneficial effects

[0028] Compared with existing known technologies, the technical solution provided by this utility model has the following beneficial effects:

[0029] (1) A continuously rotating lifting speaker movement mechanism of the present invention includes a base, an inner cylinder, a rotation damper, a lifting sleeve, and a drive assembly. The inner cylinder is directly or indirectly installed in the pivot hole of the base and can rotate relative to the base. The rotation damper is drivenly connected to the inner cylinder to provide rotational resistance to the inner cylinder and allows the inner cylinder to rotate when the torque on the inner cylinder is greater than the above-mentioned rotational resistance. The lifting sleeve and the inner cylinder are engaged by a spiral structure to enable the lifting sleeve to rotate and move up and down relative to the inner cylinder. The drive assembly is drivenly connected to the lifting sleeve to drive the lifting sleeve in both forward and reverse directions. Rotational motion; by changing the inner cylinder on the original base to a rotatable structure and using a rotational damper to provide rotational resistance to the inner cylinder, when the drive component drives the lifting sleeve to rotate, the spiral structure between the lifting sleeve and the inner cylinder can achieve simultaneous rotation and lifting motion. When the lifting sleeve moves to the stop position, it can drive the inner cylinder to overcome the rotational resistance and rotate together, thereby achieving continuous rotational motion of the lifting sleeve and providing a continuous rotational rhythm effect. Furthermore, the combination of the inner cylinder and the rotational damper results in a simple and compact structure that is easy to assemble and manufacture, with good motion stability. The rotational damper is also easy to replace if damaged.

[0030] (2) The lifting speaker motion mechanism of the present invention is capable of continuous rotation. The bottom of the inner cylinder is provided with a first transmission gear, the rotation damper is installed on the base and has a second transmission gear that meshes with the first transmission gear. The gear rotation damper has a long service life, can maintain relatively constant damping characteristics, and the transmission is stable and reliable.

[0031] (3) The first transmission gear of the present invention is assembled separately at the bottom of the inner cylinder through a snap-fit ​​structure and connected from both sides of the shaft hole during assembly so that the inner cylinder is axially limited on the base. The separate assembly structure makes it easier to manufacture the inner cylinder and the first transmission gear, and it is also easier to assemble with the base to achieve axial limitation of the inner cylinder.

[0032] (4) The present invention provides a continuously rotating lifting speaker movement mechanism, wherein the outer side wall of the inner cylinder is provided with a spiral rib, and the inner side wall of the lifting sleeve is provided with a spiral groove that cooperates with the spiral rib. The upper starting point of the spiral groove extends to the top of the lifting sleeve and is in an open state. The inner cylinder is screwed into the inner side of the lifting sleeve from the upper end and assembled thereon. The lower starting point of the spiral groove is in a closed state. When the lifting sleeve moves to the rising stop point, the lower starting point of the spiral groove abuts against the spiral rib to form the above-mentioned upper locking structure. With the above design, under the premise of ensuring stable assembly of the inner cylinder and the lifting sleeve, the upper locking structure can be formed by the lower starting point of the closed spiral groove abutting against the spiral rib, which further simplifies the structure of the inner cylinder and the lifting sleeve and helps to improve the transmission reliability between the two.

[0033] (5) The lifting and lowering speaker motion mechanism of the present invention has a lower locking structure at the lowering stop point that can drive the inner cylinder to rotate together, so that the lifting and lowering sleeve can also drive the inner cylinder to rotate continuously after it is lowered and retracted, which further enriches the action mode of the lifting and lowering speaker.

[0047] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings and embodiments.

[0048] [Example 1]

[0049] Combination Figures 1 to 3As shown, this embodiment presents a continuously rotating lifting speaker mechanism, which serves as the core transmission unit for a car lifting speaker, realizing both rotational lifting and continuous rotational movements. This lifting speaker mechanism includes a base 1, an inner cylinder 2, a rotation damper 3, a lifting sleeve 4, and a drive assembly 5. The base 1 is injection molded from plastic and has a pivot hole 1-1. The inner cylinder 2 is a hollow cylindrical structure, directly or indirectly installed within the pivot hole 1-1, and can rotate relative to the base 1. The rotation damper 3 is driven by the inner cylinder 2, providing rotational resistance and allowing the inner cylinder 2 to rotate when the torque on it exceeds this resistance. The lifting sleeve 4 is a hollow sleeve structure, with a helical connection to the inner cylinder 2, allowing it to rotate and lift relative to the inner cylinder 2. The lifting sleeve 4 has an upper locking structure at least at its rising stop point, capable of rotating the inner cylinder 2 along with it. The drive assembly 5 is driven by the lifting sleeve 4, driving it to rotate in both directions. The lifting speaker's motion mechanism drives the lifting sleeve 4 to rotate via the drive component 5. Combined with the damping action of the inner cylinder 2 and the rotation damper 3, it can achieve two motion modes: rotational lifting and continuous rotation. The specific operating principle is as follows:

[0050] The drive assembly 5 drives the lifting sleeve 4 to rotate. At this time, the spiral frictional resistance between the lifting sleeve 4 and the inner cylinder 2 is less than the rotational resistance of the rotational damper 3 on the inner cylinder 2. The inner cylinder 2 remains stationary relative to the base 1. The lifting sleeve 4 rotates and moves upward relative to the inner cylinder 2 under the action of the spiral structure. When the lifting sleeve 4 rises to its maximum height, that is, when it reaches the rising stop point, the upper locking structure takes effect. Under the action of the upper locking structure, the lifting sleeve 4 and the inner cylinder 2 are combined. Since the torque output by the drive assembly 5 acts on the inner cylinder 2, and the torque on the inner cylinder 2 is greater than the rotational resistance of the rotational damper 3 on the inner cylinder 2, the inner cylinder 2 can rotate together with the lifting sleeve 4, so that it can continue to rotate even when the lifting sleeve 4 rises to its maximum height. When the drive assembly 5 drives the lifting sleeve 4 to rotate in the opposite direction, the reverse rotational frictional resistance between the lifting sleeve 4 and the inner cylinder 2 is less than the rotational resistance of the rotational damper 3 on the inner cylinder 2. Therefore, the inner cylinder 2 remains stationary under the damping action of the rotational damper 3, and the lifting sleeve 4 rotates and moves downward relative to the inner cylinder 2 under the action of the spiral structure.

[0051] Therefore, the lifting speaker movement mechanism of this embodiment, by changing the inner cylinder 2 on the original base 1 to a rotatable structure and using the rotational damper 3 to provide rotational resistance to the inner cylinder 2, allows for simultaneous rotation and lifting motion when the driving component 5 drives the lifting sleeve 4 to rotate. Furthermore, when the lifting sleeve 4 reaches its stop position, it can drive the inner cylinder 2 to overcome the rotational resistance and rotate together, thus achieving continuous rotational motion of the lifting sleeve 4 and providing a continuous rotational rhythm effect. Moreover, the combination of the inner cylinder 2 and the rotational damper 3 results in a simple and compact structure, easy assembly and manufacturing, and good motion stability; the rotational damper 3 is a mature existing product and is easy to replace if damaged.

[0052] Reference Figure 1 and Figure 2 As shown, in this embodiment, the bottom of the inner cylinder 2 is provided with a first transmission gear 2-1, and the rotary damper 3 is mounted on the base 1, having a second transmission gear 3-1 that meshes with the first transmission gear 2-1. Through gear transmission, the transmission stability is improved. The rotary damper 3 is preferably a torque-adjustable gear damper, which has a long service life, maintains relatively constant damping characteristics, and ensures stable and reliable transmission. For ease of manufacturing and assembly, preferably, the first transmission gear 2-1 is assembled separately to the bottom of the inner cylinder 2 using a snap-fit ​​structure, and is connected from both sides of the rotating shaft hole 1-1 during assembly to axially limit the inner cylinder 2 on the base 1. This separate assembly structure makes the manufacturing of the inner cylinder 2 and the first transmission gear 2-1 more convenient, and facilitates assembly with the base 1 to achieve axial limiting of the inner cylinder 2. Specifically, a slot can be provided on the bottom inner side of the inner cylinder 2, and a buckle and a shoulder can be provided on the upper part of the first transmission gear 2-1. During assembly, the first transmission gear 2-1 is installed from the bottom of the rotating shaft hole 1-1, so that the shoulder rotates and engages with the rotating shaft hole 1-1. Then, the inner cylinder 2 is assembled and connected to the buckle of the first transmission gear 2-1 from the other side of the rotating shaft hole 1-1. At this time, the outer diameter of the inner cylinder 2 is slightly larger than the diameter of the rotating shaft hole 1-1, and the outer diameter of the first transmission gear 2-1 is also larger than the diameter of the rotating shaft hole 1-1, thereby realizing the axial positioning of the inner cylinder 2 on the base 1 and preventing the inner cylinder 2 from moving up and down.

[0053] Reference Figure 1 and Figure 3 As shown, in this embodiment, a spiral rib 2-2 is provided on the outer wall of the inner cylinder 2. The spiral rib 2-2 is integrally formed on the inner cylinder 2. A spiral groove 4-1 is provided on the inner wall of the lifting sleeve 4 to cooperate with the spiral rib 2-2. The spiral groove 4-1 is a continuous spiral groove. The spiral rib 2-2 can adopt a discontinuous spiral protrusion structure, which has a smaller contact surface with the spiral groove 4-1 to reduce the frictional resistance between it and the lifting sleeve 4, ensuring smooth and uninterrupted lifting movement when the lifting sleeve 4 rotates. Figure 3As shown, the upper starting point 4-1a of the spiral groove 4-1 extends to the top of the lifting sleeve 4 and is in an open state, allowing the inner cylinder 2 to be screwed into the inner side of the lifting sleeve 4 from the upper end, completing the assembly of the two. The lower starting point 4-1b of the spiral groove 4-1 is in a closed state. When the lifting sleeve 4 moves to the rising stop point, the lower starting point 4-1b of the spiral groove 4-1 abuts against the spiral rib 2-2 to form the aforementioned upper locking structure. At this time, the rotational torque of the lifting sleeve 4 can be transmitted to the inner cylinder 2. With the above design, under the premise of ensuring stable assembly of the inner cylinder 2 and the lifting sleeve 4, the upper locking structure can be formed by the abutting of the closed lower starting point 4-1b of the spiral groove against the spiral rib 2-2, further simplifying the structure of the inner cylinder 2 and the lifting sleeve 4, and helping to improve the transmission reliability between the two.

[0054] Furthermore, in this embodiment, the lifting sleeve 4 also has a lower locking structure at the descent stop point that can drive the inner cylinder 2 to rotate together, so that the lifting sleeve 4 can continue to drive the inner cylinder 2 to rotate even after it has descended and retracted, further enriching the operating modes of the lifting speaker. That is, when the driving component 5 drives the lifting sleeve 4 to rotate in the opposite direction and descend to the descent stop point, the lower locking structure takes effect. Under the action of the lower locking structure, the lifting sleeve 4 and the inner cylinder 2 are combined, thereby driving the inner cylinder 2 to rotate together, so that the lifting sleeve 4 can continue to rotate even when it has descended to the lowest position. Specifically, as follows... Figure 1 and Figure 2 As shown, the aforementioned lower locking structure includes a first stop 2-3 located on the upper part of the inner cylinder 2 and a second stop 4-2 located on the upper part of the lifting sleeve 4. The first stop 2-3 can be integrally formed on the inner cylinder 2, and the second stop 4-2 can be integrally formed on the connecting seat 4-4 at the top of the lifting sleeve 4 (the connecting seat 4-4 is described in detail below). When the lifting sleeve 4 moves to the lowering stop point, the second stop 4-2 abuts against the first stop 2-3 to form a lower locking structure, so that the lifting sleeve 4 can drive the inner cylinder 2 to rotate together.

[0055] catch Figure 1 and Figure 2 As shown, the drive assembly 5 in this embodiment is similar to that of the existing lifting speaker, mainly including a drive motor 5-1 and a drive gear 5-2. The drive motor 5-1 can be a stepper motor and is mounted on the base 1. The drive gear 5-2 is mounted on the output shaft of the drive motor 5-1. The outer wall of the lifting sleeve 4 is provided with an outer gear ring 4-3 that meshes with the drive gear 5-2. At least one of the drive gear 5-2 and the outer gear ring 4-3 has a wide tooth structure to ensure that the lifting sleeve 4 always maintains the meshing between the drive gear 5-2 and the outer gear ring 4-3 within the lifting stroke.

[0056] [Example 2]

[0057] This embodiment discloses a car lift-up speaker, which integrates the continuously rotating lift-up speaker motion mechanism of Embodiment 1 above, and combines it with decorative component 6, speaker component 7, mounting base 8 and exterior panel 9 to achieve a dual rhythmic experience of hearing and sight. Specifically, as Figures 4 to 9 As shown, the car lift speaker includes a trim component 6, a speaker assembly 7, a mounting base 8, an exterior trim panel 9, and the lift speaker movement mechanism of Embodiment 1 described above, wherein:

[0058] The base 1 is installed inside the mounting base 8. Specifically, the base 1 has multiple threaded holes, which can be used to fix the base 1 to the mounting base 8 with screws. The speaker assembly 7 is installed on the base 1 or at the bottom of the mounting base 8. For example, the speaker assembly 7 can be installed at the bottom of the base 1 or at the bottom of the mounting base 8. In this embodiment, it is preferable to provide a speaker mounting cylinder on the mounting base 8 to fix the speaker assembly 7 inside the speaker mounting cylinder. Figure 9 As shown, both the inner cylinder 2 and the lifting sleeve 4 are hollow structures, and the inner cylinder 2 and the lifting sleeve 4 constitute the sound outlet channel 10 of the speaker assembly 7. The speaker assembly 7 can be a vehicle-mounted tweeter.

[0059] Decorative component 6, as the core component for achieving the visual effect, includes a speaker cover 6-1 and a light-emitting unit 6-2. The speaker cover 6-1 can be a perforated metal cover, which is installed on the top of the lifting sleeve 4 to cover the sound outlet of the sound channel 10 and prevent dust from entering. The outer panel 9 is fixed to the top of the mounting base 8. The outer panel 9 has a circular hole 9-1 on it, which allows the lifting sleeve 4 to rotate and extend. The diameter of the circular hole 9-1 is slightly larger than the maximum outer diameter of the lifting sleeve 4. The light-emitting unit 6-2 is installed on the inner side of the outer panel 9 and is located around the circular hole 9-1 to achieve a surround ambient lighting effect.

[0060] like Figures 4 to 9As shown, the aforementioned light-emitting unit 6-2 includes a light source 6-2-1, a support frame 6-2-2, and a light guide strip 6-2-3. The light guide strip 6-2-3 is installed in the slot of the support frame 6-2-2, which is fixed to the back of the outer decorative panel 9. The light source 6-2-1 is installed at the light-inlet end of the light guide strip 6-2-3. The light guide strip 6-2-3 can be made of PMMA light-guiding material and is arranged in a ring along the slot of the support frame 6-2-2. The portion of the support frame 6-2-2 extending towards the center of the circular hole 9-1 is made of a light-transmitting material, which can conduct and diffuse the light within the light guide strip 6-2-3. The light source 6-2-1 is preferably an LED lamp bead, which is installed at the light-inlet end of the light guide strip 6-2-3, enabling the conduction and refraction of light using the light guide strip 6-2-3. To facilitate the manufacturing of the lifting sleeve 4 and the connection between the speaker cover 6-1 and the top of the lifting sleeve 4, a connecting seat 4-4 is installed on the top of the lifting sleeve 4 via a snap-fit ​​structure. The speaker cover 6-1 is snapped onto the connecting seat 4-4 around its perimeter. The speaker cover 6-1 is also provided with a decorative ring 6-3 installed on the connecting seat 4-4 around its perimeter. The decorative ring 6-3 is a chrome-plated ring with several reflective teeth on its outer perimeter, which can reflect light and enhance the visual quality.

[0061] This embodiment of a car lift speaker has a control section similar to existing technologies, the difference being the addition of a control mode for continuous motor rotation. In practical use, the movement of the lift speaker and the lighting effects can be linked through the vehicle control system.

[0062] Start-up phase: After the vehicle is powered on, the drive motor 5-1 starts, and the lifting sleeve 4 drives the horn cover 6-1 to rotate and rise. At the same time, the light source 6-2-1 of the light-emitting unit 6-2 is powered on and emits light, creating a dynamic start-up effect. When the lifting sleeve 4 reaches the rising stop point, it enters a continuous rotation state, and the light can change color and brightness according to the rhythm of the music.

[0063] Off-stage: When the vehicle is turned off, the drive motor 5-1 rotates in the opposite direction, and the lifting sleeve 4 drives the horn cover 6-1 to rotate and descend. After reaching the descent stop point, if it is necessary to maintain the atmosphere effect, the lifting sleeve 4 can be controlled to continue rotating in the descending position.

[0064] During normal driving: According to user needs, the lifting sleeve 4 can be controlled to rotate continuously at the rising or falling stop point, in conjunction with the rhythm of the lights, which solves the problem of the existing lifting speakers remaining stationary and greatly enhances the sense of technology and atmosphere in the car.

[0065] This utility model discloses a continuously rotating lifting speaker movement mechanism and an automotive lifting speaker, effectively solving the problem of the single action mode of existing automotive lifting speakers. By changing the inner cylinder on the original base to a rotatable structure and using a rotation damper to provide rotational resistance to the inner cylinder, the lifting sleeve can achieve simultaneous rotation and lifting motion when the drive component drives the lifting sleeve to rotate, utilizing the spiral structure between the lifting sleeve and the inner cylinder. When the lifting sleeve moves to the stop position, it can drive the inner cylinder to overcome the rotational resistance and rotate together, thereby achieving continuous rotational motion of the lifting sleeve and providing a continuous rotational rhythm effect. Furthermore, the combination of the inner cylinder and the rotation damper results in a simple and compact structure, easy assembly and manufacturing, and good motion stability. The component processing and assembly process is simple, facilitating mass production and practical application.
