Technical Field

[0002] Existing smart sunshades often use belt drive structures for propulsion. However, belts are prone to vibration and noise during long-term operation under stress. Current technologies lack effective vibration reduction designs and cannot effectively absorb the vibration generated by belt operation. This not only affects the user experience but also easily affects the operational stability of the transmission system due to vibration, making it difficult to ensure the long-term reliable operation of the belt drive system. Summary of the Invention

[0008] In one embodiment, the upper cover and / or the lower cover are provided with a connecting rod, which is connected to the abutment portion.
[0009] In one embodiment, the vibration damping mechanism further includes a tensioning assembly, the tensioning assembly comprising: An adjusting screw is provided through the abutment portion, and one end of the adjusting screw abuts against the partition plate; A slider is screwed to the adjusting screw and located between the partition and the abutment portion. One end of the elastic member abuts against the abutment portion, and the other end abuts against the slider. The slider has a through groove, and the abutting part and the mounting part are connected through the through groove.
[0010] In one embodiment, the slider includes a sleeve and an annular plate, the annular plate being sleeved on the sleeve, the sleeve being screwed to the adjusting screw, and the annular plate being slidably limited within the housing.
[0011] In one embodiment, the tensioning assembly further includes a flexible gasket disposed on the side of the partition facing the rear cavity, and the adjusting screw abuts against the flexible gasket.
[0012] In one embodiment, the housing includes an outer shell and an inner shell, the outer shell covering the inner shell, and the sliding seat slidably disposed on the inner shell.
[0013] An embodiment of the present invention also proposes an intelligent sunshade curtain, comprising: The vibration damping mechanism described above; Drive mechanism; A slide bar, the two ends of which are respectively connected to the vibration damping mechanism and the driving mechanism, and a belt is provided inside the slide bar, the two ends of which are respectively sleeved on the driving end of the driving mechanism and the pulley of the vibration damping mechanism; A trolley is connected to the belt drive and its sliding limit is located at the slide rod. One end of the trolley is connected to the curtain.
[0014] In one embodiment, the drive mechanism includes a motor and a reducer, the output end of the motor is connected to the input end of the reducer, the output end of the reducer is connected to the belt, and the motor, the slide bar and the vibration damping mechanism are coaxially arranged.
[0015] This invention addresses the issue of vibration reduction by configuring one of the fixed ends of the intelligent sunshade belt as a slidable structure, allowing it to be elastically connected to the housing via an elastic element. This enables the vibration generated by the belt's operation to be transmitted to the elastic element, which absorbs the energy of the vibration through deformation, thus achieving vibration reduction and lowering vibration sensation and noise. Specifically, the vibration reduction mechanism includes a housing, a sliding seat, and an elastic element. The housing is internally divided into a front cavity and a rear cavity by a partition. The sliding seat includes an abutment portion for contacting the elastic element and a mounting portion for mounting and fixing the pulley of the belt. The mounting portion is located in the front cavity, and the abutment portion is located in the rear cavity. The elastic element abuts against both the abutment portion and the partition. When the belt vibrates during operation, the vibration is transmitted to the pulley and acts on the mounting portion of the sliding seat. Since the sliding seat is slidably mounted on the housing, and its only pressure point is the abutment portion, the vibration is further transmitted to the elastic element through the abutment portion. Ultimately, the elastic element deforms to absorb the energy of the vibration, achieving a vibration reduction effect. Attached Figure Description

[0022] Existing intelligent sunshade curtains generally employ belt drive structures in conjunction with drive mechanisms to drive the opening and closing of the curtain. The belt is wound and tensioned between the drive end and the driven end, and a trolley is connected to the belt drive and drives the curtain to slide along a sliding rod. During the actual operation of the intelligent sunshade curtain, the belt is always under tension and undergoes cyclic transmission motion with the operation of the drive mechanism. The elastic deformation of the belt itself, the contact friction between the belt and the transmission components, and the tension fluctuations of the belt during transmission all cause continuous vibration of the belt. This vibration is transmitted along the belt to the connected drive end, driven end, and sliding rod, thereby causing resonance in each structural component.
[0023] In related technologies, the belt fixing ends of smart sunshades all adopt a rigid connection structure design, lacking a targeted vibration damping and buffer structure. This makes it impossible to effectively absorb and dissipate the vibration energy generated during belt operation, causing vibration to continuously transmit and spread in the transmission system. It is impossible to effectively suppress the vibration generated by belt drive, nor can it block the transmission path of vibration. Ultimately, this results in obvious vibration when the smart sunshade is working, and the noise problem caused by vibration is prominent, which seriously affects the actual user experience. At the same time, long-term vibration impact will also aggravate the wear between transmission components, damage the operational stability of the belt drive system, significantly reduce the service life of the belt and various transmission structures, and make it difficult to guarantee the long-term reliable working performance of the smart sunshade belt drive system.
[0024] To address the aforementioned problems, this invention proposes a vibration damping mechanism 100 to solve or at least alleviate the technical problems mentioned above.
[0025] Please see Figure 1 and combined Figure 2 In one embodiment of the present invention, the vibration damping mechanism 100 is applied to an intelligent sunshade curtain, including a housing 1, a sliding seat 2 and an elastic member 3. The housing 1 is provided with a partition, and the opposite sides of the partition form a front cavity 1a and a rear cavity 1b, respectively. The sliding seat 2 is slidably disposed on the housing 1. The sliding seat 2 includes a connecting abutment part 21 and a mounting part 22. The mounting part 22 is located in the front cavity 1a, and the abutment part 21 is located in the rear cavity 1b. The mounting part 22 is provided with a pulley 23. One end of the elastic member 3 abuts against the partition, and the other end abuts against the abutment part 21.
[0026] It is understandable that by configuring the driven end (i.e. the end away from the drive mechanism 200) of the smart sunshade belt 310 as a sliding structure, the fixed end is elastically connected to the housing 1 via the elastic element 3. The vibration generated by the belt 310 during operation can be transmitted to the elastic element 3 along the transmission path. The elastic deformation of the elastic element 3 absorbs and dissipates the kinetic energy generated by the vibration, thereby achieving a vibration reduction effect and effectively reducing the vibration and noise of the smart sunshade during operation.
[0027] Specifically, the partition inside the housing 1 divides the interior of the housing 1 into two independent front cavities 1a and rear cavities 1b. The sliding seat 2 is slidably fitted to the housing 1. Its integrally formed abutment part 21 and mounting part 22 are respectively adapted to be accommodated in the rear cavity 1b and the front cavity 1a. The mounting part 22 is provided with a pulley 23 for the belt 310 to be wound around. The driven end of the belt 310 is wound and fixed on the pulley 23. The elastic member 3 is in a compressed state and abuts against the partition and the abutment part 21 to form an elastic support for the sliding seat 2.
[0028] When the smart sunshade is working, the belt 310 vibrates due to the drive transmission. The vibration first acts on the pulley 23 connected to the belt 310, and then is transmitted to the mounting part 22 of the sliding seat 2. Since the sliding seat 2 and the housing 1 are in a sliding fit relationship, and the sliding seat 2 is only subjected to the abutting force of the elastic member 3 at the abutting part 21, the vibration force on the mounting part 22 will be transmitted along the body of the sliding seat 2 to the abutting part 21 of the rear cavity 1b. The abutting part 21 transmits the vibration force to the elastic member 3 that abuts it. The elastic member 3 undergoes elastic deformation under this force. During the deformation process, it absorbs the energy generated by the vibration, effectively attenuating the vibration and preventing the vibration from continuing to be transmitted and diffused along the housing 1 and other structures, thereby achieving vibration reduction of the smart sunshade and reducing the noise caused by vibration.
[0029] It should be noted that this application does not limit the specific form of the elastic element 3. Please refer to [link / reference]. Figure 1 In one embodiment of this application, the elastic element 3 adopts a compression spring structure. The compression spring is axially compressed and is disposed between the partition and the abutment part 21. One end of the compression spring abuts against the side of the partition facing the abutment part 21, and the other end of the compression spring abuts against the side of the abutment part 21 facing the partition. The axial extension direction of the compression spring is consistent with the sliding direction of the sliding seat 2. The sliding force generated by the vibration of the sliding seat 2 can directly act on the compression spring, causing the compression spring to undergo axial elastic deformation to absorb vibration energy.
[0030] In another embodiment of this application, the elastic element 3 adopts a rubber elastic column structure. The rubber elastic column is a hollow column structure, which is fixed between the partition and the abutment part 21. The two ends of the rubber elastic column abut against the partition and the abutment part 21 respectively. The rubber elastic column has elastic deformation characteristics. When the abutment part 21 is vibrated and moves towards the partition, the rubber elastic column is squeezed and undergoes elastic deformation. It absorbs the energy generated by the vibration through its own elastic restoring force and blocks the transmission path of the vibration.
[0031] In another embodiment of this application, the elastic element 3 uses a structure of repulsion between like magnets to achieve elastic contact. A first magnet is fixedly installed on the side of the partition facing the contact portion 21, and a second magnet is fixedly installed on the side of the contact portion 21 facing the partition. The magnetic poles of the first and second magnets are of the same polarity. The repulsive force between the like magnetic poles forms an elastic force, keeping the first and second magnets in contact with the partition and the contact portion 21 respectively. When the vibration generated by the belt 310 is transmitted to the contact portion 21, driving the contact portion 21 to move towards the partition, the distance between the first and second magnets decreases, and the repulsive force between the like magnetic poles increases accordingly. The reaction force of the repulsive force cancels out the force generated by the vibration. At the same time, the contact portion 21 is displaced in the opposite direction under the action of the repulsive force. Under the action of the magnetic pole repulsion, the vibration energy is absorbed and dissipated. When the vibration force of the contact portion 21 disappears, the repulsive force between the magnetic poles drives the contact portion 21 to return to its original position, always maintaining elastic support for the sliding seat 2, thereby achieving a vibration reduction effect.
[0032] Please see Figure 4 In one embodiment of this application, since there is tension between the pulley 23 and the belt 310, a mounting part 22 includes an upper cover 221 and a lower cover 222, which are joined together to form a mounting cavity, in order to achieve reliable installation of the pulley 23. The split structure of the upper cover 221 and the lower cover 222 allows for disassembly and assembly. During assembly, the pulley 23 can be placed in the preset mounting position of the lower cover 222 first, and then the upper cover 221 is placed on top of the lower cover 222 and the splicing is completed and fixed, so that the pulley 23 is confined within the mounting cavity formed by the enclosure, thus realizing convenient assembly of the pulley 23.
[0033] Meanwhile, this splicing structure provides circumferential and axial limiting protection for the pulley 23 within the mounting cavity, preventing radial displacement or axial dislodgement of the pulley 23 during rotation and ensuring the rotational stability of the pulley 23 within the mounting cavity. Furthermore, the split splicing structure facilitates subsequent replacement and maintenance of the pulley 23 within the mounting cavity. The pulley 23 can be accessed simply by removing the upper cover 221, eliminating the need to disassemble the entire mounting section 22, thus improving maintenance convenience. The mounting cavity formed by the splicing of the upper cover 221 and the lower cover 222 creates a closed protective space, reducing the entry of external dust and debris into the mounting cavity and preventing contact with the pulley 23. This prevents foreign objects from affecting the smoothness of rotation of the pulley 23 and ensures the transmission stability of the pulley 23.
[0034] Please continue reading. Figure 4Based on the above embodiments, to further ensure the reliability of the pulley 23's fixation, a first mounting sleeve 2211 is integrally formed on the side of the upper cover 221 facing the mounting cavity, and a first bearing 2212 is fixedly embedded in the inner hole of the first mounting sleeve 2211. A second mounting sleeve 2221 is integrally formed on the side of the lower cover 222 facing the mounting cavity, corresponding to the position of the first mounting sleeve 2211, and a second bearing 2222 is fixedly embedded in the inner hole of the second mounting sleeve 2221. The first bearing 2212 and the second bearing 2222 are coaxially arranged. The shaft 25 passes through the inner ring of the first bearing 2212 and the inner ring of the second bearing 2222, and forms a fixed fit with the first bearing 2212 and the second bearing 2222. The shaft 25 is mounted inside the mounting cavity through the two bearings. The pulley 23 is rotatably sleeved on the shaft 25, and the two axial ends of the pulley 23 abut against the first bearing 2212 and the second bearing 2222 respectively, so that the pulley 23 is limited to the shaft 25 section between the first bearing 2212 and the second bearing 2222.
[0035] Understandably, during operation, the belt 310 drives the pulley 23 to rotate around the shaft 25. The shaft 25 forms a rotational fit with the upper cover 221 and the lower cover 222 through the first bearing 2212 and the second bearing 2222, respectively. This converts the sliding friction between the pulley 23 and the mounting part 22 into rolling friction between the inner and outer rings of the bearings, significantly reducing the frictional resistance during the rotation of the pulley 23, ensuring the smoothness of the pulley 23's rotation, and reducing vibration and noise caused by friction. At the same time, the coaxially arranged first bearing 2212 and second bearing 2222 provide bidirectional axial limiting and radial support for the shaft 25, preventing radial offset or axial movement of the shaft 25 during the rotation of the pulley 23. This ensures the installation stability of the shaft 25, thereby ensuring that the pulley 23 always rotates coaxially and preventing misalignment friction between the pulley 23 and the belt 310 due to positional offset, thus ensuring the transmission fit accuracy between the belt 310 and the pulley 23.
[0036] Please see Figure 3 To ensure a reliable connection between the mounting portion 22 located in the front cavity 1a and the abutment portion 21 located in the rear cavity 1b, a connecting rod 24 is provided on the upper cover 221 and / or the lower cover 222. The connecting rod 24 can be provided on the upper cover 221, the lower cover 222, or both. A through hole is provided in the partition for the connecting rod 24 to pass through. One end of the connecting rod 24 is fixedly connected to the upper cover 221 and / or the lower cover 222, and the other end of the connecting rod 24 passes through the through hole and is fixedly connected to the abutment portion 21. This achieves a rigid connection between the mounting portion 22 and the abutment portion 21, so that the mounting portion 22 and the abutment portion 21 are respectively located in the front cavity 1a and the rear cavity 1b formed by the partition, and the two form a linkage structure through the connecting rod 24.
[0037] Specifically, the connecting rod 24 and the through hole of the partition have a certain clearance, which provides a guide for the movement of the connecting rod 24, preventing radial displacement of the connecting rod 24 during sliding with the sliding seat 2, ensuring the sliding synchronization of the mounting part 22 and the abutment part 21, and also limits the connecting rod 24 through the through hole, preventing the sliding seat 2 from rotating circumferentially within the housing 1, ensuring that the sliding seat 2 always slides in the preset direction. As a force transmission component between the mounting part 22 and the abutment part 21, the connecting rod 24 can stably transmit the force generated by the vibration of the belt 310 on the mounting part 22 to the abutment part 21, and then the abutment part 21 transmits the force to the elastic member 3, ensuring the effective transmission of vibration energy and ensuring that the elastic member 3 can absorb vibration energy in time to achieve vibration reduction. At the same time, the rigid structure of the connecting rod 24 can prevent relative displacement between the mounting part 22 and the abutment part 21, ensuring the overall structural stability and motion consistency of the sliding seat 2.
[0038] To avoid interference between the connecting rod 24 and the slider 42, the slider 42 is provided with a through groove 42a, through which the connecting rod 24 passes.
[0039] It should be noted that the belt 310 is prone to creep and loosening due to stress during long-term operation. In view of this, the vibration damping mechanism 100 proposed in this application also includes a tensioning component 4, which can adjust the tension of the belt 310 to ensure that the belt 310 is always within a suitable tension range.
[0040] Please see Figure 1 and combined Figure 3 Specifically, the tensioning assembly 4 includes an adjusting screw 41 and a slider 42. The adjusting screw 41 passes through the abutment portion 21 and one end abuts against the partition plate. The slider 42 is screwed to the adjusting screw 41 and its sliding limit is located within the housing 1, between the partition plate and the abutment portion 21. One end of the elastic element 3 abuts against the abutment portion 21, and the other end abuts against the slider 42. When it is necessary to adjust the tension of the belt 310, the end of the adjusting screw 41 exposed on the side of the abutment portion 21 facing away from the slider 42 is turned. Since one end of the adjusting screw 41 abuts against the partition plate and cannot undergo axial displacement, its rotation will cause the screwed slider 42 to move linearly along the axial direction of the adjusting screw 41.
[0041] When the slider 42 moves toward the partition, the distance between the slider 42 and the abutment 21 increases, the compression of the elastic element 3 decreases, and the elastic thrust of the elastic element 3 on the abutment 21 decreases accordingly. Under the pull-back force of the belt 310, the sliding seat 2 moves toward the partition, and the pulley 23 moves synchronously with the sliding seat 2, and the tension of the belt 310 decreases accordingly.
[0042] When the slider 42 moves closer to the abutment 21, the distance between the slider 42 and the abutment 21 decreases, the compression of the elastic element 3 increases, and the elastic thrust of the elastic element 3 on the abutment 21 increases accordingly, pushing the abutment 21 to drive the sliding seat 2 to move away from the partition. The pulley 23 moves synchronously with the sliding seat 2 and pulls the belt 310, thereby increasing the tension of the belt 310 accordingly.
[0043] By turning the adjusting screw 41 to change the axial position of the slider 42, the compression deformation of the elastic element 3 is adjusted, thereby changing the elastic force applied by the elastic element 3 to the sliding seat 2, causing the sliding seat 2 to generate an adaptive axial displacement along the housing 1, realizing precise adjustment of the position of the pulley 23, thereby adjusting the tension of the belt 310, so that the belt 310 always maintains a suitable tension, avoiding excessive wear of the belt 310 due to excessive tension, and slippage and free rotation due to insufficient tension. At the same time, the tension can be compensated and adjusted according to the wear of the belt 310, ensuring the stability and reliability of the belt 310 transmission.
[0044] Please see Figure 3 In one embodiment of this application, the slider 42 includes a sleeve 421 and an annular plate 422. The sleeve 421 and the annular plate 422 form a fixed fit. The inner hole of the sleeve 421 is provided with an internal thread, which forms a threaded fit with the adjusting screw 41. The outer peripheral wall of the annular plate 422 is adapted to the inner wall of the housing 1 to form a sliding limit fit, so that the slider 42 can only move linearly along the axial direction of the housing 1 and cannot rotate circumferentially or deflect radially.
[0045] This split design modularly separates the threaded transmission function and sliding limit function of the slider 42. The sleeve 421 is used to achieve a threaded engagement with the adjusting screw 41. The machining accuracy and fit strength of the internal thread can be specifically optimized to ensure the smoothness and precision of the threaded transmission with the adjusting screw 41, avoiding axial movement jamming of the slider 42 due to thread fit errors. The annular plate 422 is used to achieve a sliding limit engagement with the housing 1. Its outer peripheral wall can be adapted to the structural characteristics of the inner wall of the housing 1 to ensure a good fit with the inner wall of the housing 1, achieving a stable sliding guide and limit effect, and preventing the slider 42 from deflecting during axial movement. At the same time, the split structure allows for the selection of suitable machining materials for the sleeve 421 and the annular plate 422 according to actual usage requirements. The sleeve 421 is made of a wear-resistant and high-strength material to ensure the durability of the threaded transmission, while the annular plate 422 is made of a material with a low coefficient of friction and good self-lubricating properties to reduce sliding friction resistance with the inner wall of the housing 1 and improve the overall smoothness of the slider 42's movement.
[0046] Please continue reading. Figure 3The tensioning assembly 4 also includes a flexible gasket 43, which is located on the side of the partition facing the rear cavity 1b. The adjusting screw 41 abuts against the flexible gasket 43. This arrangement creates an isolation structure between the end of the adjusting screw 41 and the partition, preventing direct contact and pressure friction between the end of the adjusting screw 41 and the hard surface of the partition. During the process of adjusting the tension of the belt 310 by turning the adjusting screw 41, the adjusting screw 41 will undergo a slight axial displacement, and its end will continuously contact and compress with the abutment surface. The flexible gasket 43 can withstand wear through its own contact friction with the end of the adjusting screw 41. When the flexible gasket 43 wears out, it can be directly disassembled and replaced without the need for overall repair or replacement of the partition, effectively reducing maintenance costs while ensuring the integrity of the partition structure and ensuring that the adjusting screw 41 always maintains a stable axial abutment state.
[0047] Furthermore, the flexible gasket 43 is made of a flexible material with elastic deformation properties, and it elastically abuts against the end of the adjusting screw 41, forming an elastic connection between the adjusting screw 41 and the partition. During the operation of the intelligent sunshade, the vibration generated by the belt 310 is transmitted through the sliding seat 2 and the elastic element 3, and some of the vibration energy is transmitted to the adjusting screw 41. The slight axial vibration generated by the adjusting screw 41 will act on the flexible gasket 43, causing the flexible gasket 43 to undergo elastic deformation. The deformation process of the flexible gasket 43 further absorbs and dissipates the remaining vibration energy, preventing this part of the vibration energy from being transmitted to the partition through the adjusting screw 41 and propagated along the structure of the shell 1, thus achieving secondary attenuation of vibration. Meanwhile, the elastic contact of the flexible pad 43 can buffer the slight shaking caused by the vibration of the adjusting screw 41, prevent the adjusting screw 41 from becoming loose or shifting position due to vibration, ensure the structural stability of the tensioning assembly 4, and thus ensure the constant tension of the belt 310, ensuring the overall vibration reduction effect of the vibration damping mechanism 100 and the reliability of the belt 310 transmission.
[0048] Please see Figure 1 The housing 1 of this application adopts a double-layer structure design with an outer shell 11 and an inner shell 12. The outer shell 11 is fitted over the outer side of the inner shell 12, making the inner shell 12 the internal support structure of the housing 1, while the outer shell 11 forms the external protective and decorative structure of the housing 1. The sliding seat 2 and all functional components inside the housing 1 are assembled into the inner shell 12 and form a mating relationship with it. The inner wall surface of the inner shell 12 is designed to adapt to the sliding trajectory of the sliding seat 2 and the installation requirements of each component, ensuring that the sliding seat 2 slides smoothly in a preset direction. At the same time, it provides fixed mounting positions for internal components such as partitions, elastic elements 3, and tensioning components 4, so that each component forms a precise assembly and mating relationship within the housing 1, ensuring the operational stability of the internal transmission and vibration damping structure of the vibration damping mechanism 100.
[0049] As the exposed structure of the housing 1, the outer shell 11 has a smooth and regular outer surface design to form an aesthetically pleasing appearance, effectively improving the overall appearance and texture of the vibration damping mechanism 100 and matching the overall design style of the smart sunshade. At the same time, the outer shell 11 covers the outer side of the inner shell 12, which can protect the inner shell 12 and various functional components, reduce the impact of external bumps, dust, moisture and other factors on the internal components, prevent the inner shell 12 and internal components from wear and corrosion due to external factors, and extend the service life of the vibration damping mechanism 100.
[0050] This invention also proposes an intelligent sunshade curtain, which includes the vibration damping mechanism 100, drive mechanism 200, slide rod 300, and trolley 400 as described above. Both ends of the slide rod 300 are connected to the vibration damping mechanism 100 and drive mechanism 200, respectively. A belt 310 is provided inside the slide rod 300, with both ends of the belt 310 respectively sleeved on the drive end of drive mechanism 200 and pulley 23 of vibration damping mechanism 100. The trolley 400 is drively connected to belt 310 and its sliding limit is located within the slide rod 300. One end of the trolley 400 is connected to the curtain body. The specific structure of the vibration damping mechanism 100 is as described in the above embodiments. Since this intelligent sunshade curtain adopts all the technical solutions of all the above embodiments, it possesses at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be elaborated further here.
[0051] Please see Figure 5 It is understandable that after the drive mechanism 200 is started, it outputs driving force to its drive end. The driving force drives the belt 310 inside the slide rod 300 to perform cyclic transmission motion. The trolley 400, which forms a transmission cooperation with the belt 310, is driven by the transmission force of the belt 310 and performs linear sliding motion along the slide rod 300. The trolley 400 simultaneously pulls the curtain connected to it to realize the opening and closing action of the curtain.
[0052] Please see Figure 5 Combination Figure 7 During the opening and closing of the curtain, the belt 310 is driven and continuously vibrates. This vibration is transmitted along the belt 310 to the pulley 23 of the vibration damping mechanism 100 around which it is wound. The pulley 23 transmits the vibration force to the mounting part 22 of the sliding seat 2. Since the sliding seat 2 is slidably mounted on the housing 1 of the vibration damping mechanism 100, and the abutting part 21 of the sliding seat 2 abuts against the elastic member 3, the vibration force on the mounting part 22 is transmitted along the sliding seat 2 to the abutting part 21. The abutting part 21 transmits the vibration force to the elastic member 3. The elastic member 3 undergoes elastic deformation under vibration. During the deformation process, it absorbs and dissipates the energy generated by the vibration, thereby effectively attenuating the vibration of the belt 310, preventing the vibration from being transmitted along the slide rod 300 to the drive mechanism 200 and other structures, and at the same time reducing the noise caused by the vibration.
[0053] The two ends of the slide bar 300 are connected to the vibration damping mechanism 100 and the drive mechanism 200 respectively, so that the belt 310 is always tensioned between the drive end of the drive mechanism 200 and the pulley 23 of the vibration damping mechanism 100, ensuring stable transmission between the belt 310, the drive end, and the pulley 23, and ensuring that the driving force can be stably transmitted to the trolley 400 to achieve smooth opening and closing of the curtain. The sliding limit of the trolley 400 is located at the slide bar 300, so that the trolley 400 always slides along the preset trajectory of the slide bar 300, avoiding the trolley 400 from deviating and causing the curtain to open and close awkwardly, thus ensuring the operational stability of the intelligent sunshade curtain.
[0054] Please see Figure 6 In one embodiment, the drive mechanism 200 adopts a transmission structure design in which a motor 210 and a reducer 220 cooperate. The output end of the motor 210 is connected to the input end of the reducer 220. The output end of the reducer 220 is connected to the belt 310 inside the slide bar 300. The reducer 220 reduces the power output of the motor 210 and increases the torque to match the power requirements of the opening and closing of the smart sunshade curtain. This ensures that the torque and speed of the belt 310 are within the appropriate range, avoiding excessive opening and closing of the curtain and excessive impact due to excessive output speed of the motor 210. At the same time, it increases the driving force of the belt 310, ensuring that the curtain can complete the opening and closing action smoothly and stably, thus ensuring the operational stability of the smart sunshade curtain.
[0055] The motor 210, slide bar 300, and vibration damping mechanism 100 are arranged in a coaxial configuration, so that the central axes of the three are collinear. The belt 310 is tensioned along this coaxial direction between the output end of the drive mechanism 200 and the pulley 23 of the vibration damping mechanism 100. This ensures that the transmission direction of the belt 310 is consistent with the extension direction of the slide bar 300, avoids uneven wear or jamming of the belt 310 due to axis misalignment, improves the matching accuracy between the belt 310 and each transmission component, and reduces additional vibration and wear during the transmission process of the belt 310.
[0056] Meanwhile, the coaxial structure allows for a more compact overall transmission structure layout for the smart sunshade, effectively reducing installation space and improving the space utilization of the structure. Furthermore, this coaxial layout allows the vibration force transmitted by the belt 310 to be directly transmitted to the vibration damping mechanism 100 along the axial direction, enabling the vibration damping mechanism 100 to accurately receive and absorb vibration energy. This avoids the vibration force from being offset by the axial force, which would cause the vibration damping effect to decrease. It ensures the absorption and dissipation effect of the vibration damping mechanism 100 on the vibration of the belt 310, further improving the vibration reduction and noise reduction performance of the smart sunshade.
[0057] Please see Figure 8In one embodiment of this application, a tensioner 320 is also provided inside the slide bar 300. The tensioner 320 is slidably disposed on the slide bar 300 and can be locked at any position of the slide bar 300. The first transition shaft 321 of the tensioner 320 and the second transition shaft 330 disposed inside the slide bar 300 tighten the belt 310 into an S-shape. When the tensioner 320 moves along the slide bar 300, it drives the first transition shaft 321 to move, and the relative distance between the first transition shaft 321 and the second transition shaft 330 increases, and the belt 310 is further tightened, thereby ensuring that the belt 310 has a suitable tension.
[0058] Please see Figure 5 This intelligent sunshade also includes multiple support seats 500. The multiple support seats 500 are evenly spaced along the length of the slide rod 300. One end of the support seat 500 is fixed to the wall, and the other end forms a groove to support the slide rod 300.
