Description

Technical Field

[0001] This utility model relates to the field of flatness optimization technology, and more specifically, to a flatness optimization device for vehicle backlight components. Background Technology

[0002] With the rapid development of the automotive industry and the increasing demands of consumers for vehicle interior quality, in-vehicle display systems, as an important component of vehicle interiors, are receiving increasing attention for their performance and appearance quality. In-vehicle backlight components, such as displays and backlight panels, are key components of the display system, and their flatness directly affects the display effect and user experience. However, during the manufacturing process, due to the influence of residual stress, in-vehicle backlight components often fail to achieve the ideal flatness requirements, leading to problems such as reflection, color difference, and uneven display, which in turn affect the overall visual effect and driving safety.

[0003] In recent years, vibration technology, as an emerging processing and optimization method, has been gradually applied in various fields. By precisely controlling vibration parameters, residual stress inside products can be eliminated, resulting in minute physical deformations of materials, thereby improving their shape and performance. It is evident that vibration technology has significant advantages in eliminating residual stress inside products and optimizing their flatness. Therefore, applying vibration technology to optimize the flatness of automotive backlights has become an important research direction for improving the quality of automotive display systems. Utility Model Content

[0004] The purpose of this utility model is to provide a planarity optimization device for vehicle backlight components. By setting up a frame, a clamping assembly and a vibration assembly, residual stress inside the vehicle backlight component is eliminated, thereby achieving efficient and precise planarity optimization of the vehicle backlight component and providing strong technical support for improving the quality of vehicle display systems.

[0005] A planarity optimization device for an automotive backlight assembly includes a frame, a clamping assembly, and a vibration assembly. The frame is used to place the automotive backlight assembly. The clamping assembly includes a clamping shaft, a carrier, and at least one vibration head. The clamping shaft is mounted parallel to the upper end of the frame. The carrier is connected to the clamping shaft and is located between the clamping shaft and the frame. The vibration head is located on the carrier. The vibration assembly is used to drive the vibration head to vibrate.

[0006] In the above technical solution, the frame serves as the support platform for the entire device, used to stably place the automotive backlight assembly. The clamping assembly includes a clamping shaft, a carrier, and a vibrating head. The clamping shaft is mounted parallel to the upper end of the frame, providing a stable support structure. The carrier is connected to the clamping shaft and located between the clamping shaft and the frame, used to support the vibrating head. The vibration assembly is responsible for driving the vibrating head to vibrate, thereby eliminating residual stress inside the automotive backlight assembly and optimizing the flatness of the automotive backlight assembly. After the automotive backlight assembly is correctly placed on the frame and fixed, the vibration assembly is activated. The vibration energy generated by the vibration assembly is transmitted to the vibrating head through the clamping shaft and the carrier. The precise vibration waveform generated by the vibrating head acts on the surface of the automotive backlight assembly, making minor adjustments to the surface of the backlight assembly, gradually making it more flat. During the optimization process, the vibration energy is effectively transferred to the critical areas of the automotive backlight assembly, while avoiding unnecessary damage or stress concentration to the assembly. This invention eliminates residual stress inside the vehicle backlight assembly by setting up a frame, clamping assembly, and vibration assembly, thereby achieving efficient and precise flatness optimization of the vehicle backlight assembly and providing strong technical support for improving the quality of vehicle display systems.

[0007] Furthermore, the vibration assembly includes an ultrasonic generator and an amplitude transformer, one end of which is connected to the output end of the ultrasonic generator, and the other end is connected to the clamp shaft.

[0008] In the above technical solution, the amplitude transformer, as a key component for vibration transmission, has the function of amplifying the vibration amplitude. This means that the vibration energy output from the ultrasonic generator will be enhanced to a certain extent after passing through the amplitude transformer, thus acting more effectively on the backlight assembly. At the same time, due to the direct connection between the amplitude transformer and the clamp shaft, the vibration energy can be directly transmitted to the vibrating head connected to the clamp shaft, and then act on the backlight assembly.

[0009] Furthermore, there is one ultrasonic generator and two amplitude transformers, which are arranged opposite each other on both sides of the frame, and the ultrasonic generator is connected to the two amplitude transformers.

[0010] In the above technical solution, the two amplitude transformers are positioned opposite each other on both sides of the frame, ensuring a more even distribution of vibration energy on the backlight assembly. Since an amplitude transformer is connected to each end of the clamp shaft, the vibration energy generated by the ultrasonic generator can be applied to both ends of the clamp shaft through the two amplitude transformers, avoiding the problem of uneven vibration of the clamp shaft caused by unilateral vibration. Furthermore, by designing a single ultrasonic generator to drive the vibration of the two amplitude transformers, the electrical signal generated by the single ultrasonic generator is simultaneously distributed to both amplitude transformers. The system structure is relatively simple, low-cost, and easy to control and maintain.

[0011] Furthermore, there are two ultrasonic generators and two amplitude transformers, which are arranged opposite each other on both sides of the frame, and the two ultrasonic generators are respectively connected to the two amplitude transformers.

[0012] In the above technical solution, two ultrasonic generators are used, each independently driving an amplitude transformer to produce mechanical vibration. This approach provides greater flexibility and independence, ensuring a stable energy supply to each amplitude transformer and avoiding uneven energy distribution. Furthermore, the parameters of the two ultrasonic generators can be adjusted separately as needed to optimize the working effect.

[0013] Furthermore, the vibration assembly also includes a connecting rod, the two ends of which are respectively connected to the two amplitude transformers.

[0014] In the above technical solution, the connection between the connecting rod and the two amplitude transformers helps to further balance the vibration distribution. During vibration, the connecting rod can coordinate the vibration amplitude and phase of the two amplitude transformers, so that the vibration energy they generate can complement and balance each other, thereby forming a more uniform and stable vibration field on the backlight assembly.

[0015] Furthermore, the amplitude transformer is provided with a first waist-shaped hole and a second waist-shaped hole, and the clamp shaft and the connecting rod are respectively passed through the first waist-shaped hole and the second waist-shaped hole.

[0016] In the above technical solution, the design of the oblong hole allows for a certain degree of adjustment of the clamp shaft and connecting rod on the amplitude transformer, enabling the vibration assembly to adapt to vehicle backlight assemblies of different sizes and shapes, thus improving the versatility and practicality of the device. Users can adjust the position of the clamp shaft and connecting rod according to actual needs to ensure that the vibration energy can be accurately applied to the backlight assembly.

[0017] Furthermore, the carrier is provided with a plurality of grooves evenly spaced along its width direction, and the vibrating head is disposed in the groove.

[0018] In the above technical solution, slots are set on the carrier at uniform intervals along its width direction, and each slot is equipped with a vibration head, which realizes simultaneous vibration of multiple points of the backlight assembly, improves the uniformity and comprehensiveness of vibration coverage, and helps to improve the flatness of the backlight assembly more quickly.

[0019] Furthermore, the trough extends along the length of the vehicle.

[0020] In the above technical solution, the tank is designed to extend along the length of the carrier, making the vibration trajectory formed by the vibrating head on the backlight assembly more continuous and uniform. This design helps to reduce dead zones and blind spots during vibration, improving the utilization rate and optimization effect of vibration energy.

[0021] Furthermore, the end of the vibrating head facing the frame is circular.

[0022] In the above technical solution, designing the end of the vibrating head facing the frame as circular helps reduce localized impacts and stress concentrations during vibration. The circular design has a better ability to disperse vibration energy, making the vibration more uniform and stable, thereby protecting the backlight assembly from damage and improving the optimization effect.

[0023] Furthermore, the frame is provided with multiple horizontal adjustment components on the side away from the vibrating head.

[0024] In the above technical solution, a leveling adjustment component is installed on the side of the frame away from the vibration head, allowing the user to adjust the level of the frame according to actual needs. This ensures that the backlight assembly remains in a stable horizontal state during optimization, avoiding uneven vibration and poor optimization results caused by frame tilt. At the same time, the leveling adjustment component also improves the ease of use and operation of the device.

[0025] Compared with existing technologies, the beneficial effects of this invention are: by designing the frame, fixture assembly, and vibration assembly, effective flatness optimization can be achieved for automotive backlight assemblies. The frame provides a stable working platform, and the fixture assembly includes a fixture shaft, a carrier, and at least one vibration head. The vibration assembly transmits its own generated vibration energy to the vibration head through the fixture shaft and carrier, and then the vibration head applies vibration to the backlight assembly, thereby improving its flatness and increasing the processing accuracy and yield of the backlight assembly.

[0036] The planarity optimization device for vehicle-mounted backlight components of this utility model will be described in further detail below with reference to specific embodiments and accompanying drawings. The accompanying drawings show preferred embodiments of this utility model. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein.

[0037] Please refer to Figure 1 In a preferred embodiment, the vehicle backlight assembly flatness optimization device of the present invention includes a frame 1, a clamp assembly 2, and a vibration assembly 3. The frame 1 is used to place the vehicle backlight assembly. The clamp assembly 2 includes a clamp shaft 201, a carrier 202, and at least one vibration head 203. The clamp shaft 201 is mounted parallel to the upper end of the frame 1. The carrier 202 is connected to the clamp shaft 201 and is located between the clamp shaft 201 and the frame 1. The vibration head 203 is located on the carrier 202. The vibration assembly 3 is used to drive the vibration head 203 to vibrate.

[0038] In practical application, the frame 1 serves as the support platform for the entire device, used to stably place the vehicle backlight assembly. The clamp assembly 2 includes a clamp shaft 201, a carrier 202, and a vibration head 203. The clamp shaft 201 is mounted parallel to the upper end of the frame 1, providing a stable support structure. The carrier 202 is connected to the clamp shaft 201 and located between the clamp shaft 201 and the frame 1, used to support the vibration head 203. The vibration assembly 3 drives the vibration head 203 to vibrate, thereby eliminating residual stress inside the vehicle backlight assembly and optimizing its flatness. Once the vehicle backlight assembly is correctly placed on the frame 1 and fixed, the vibration assembly 3 is activated. The vibration energy generated by the vibration assembly 3 is transmitted to the vibration head 203 through the clamp shaft 201 and the carrier 202. The precise vibration waveform generated by the vibration head 203 acts on the surface of the vehicle backlight assembly, making minor adjustments to the surface and gradually flattening it. During the optimization process, vibration energy is effectively transferred to the critical areas of the vehicle backlight assembly, while avoiding unnecessary damage or stress concentration to the assembly. This invention, by setting up a frame 1, a clamping assembly 2, and a vibration assembly 3, achieves efficient and precise flatness optimization of the vehicle backlight assembly, providing strong technical support for improving the quality of vehicle display systems.

[0039] Specifically, the vibration assembly 3 includes an ultrasonic generator 301 and an amplitude transformer 302. One end of the amplitude transformer 302 is connected to the output end of the ultrasonic generator 301, and the other end is connected to the clamp shaft 201. The core of the vibration assembly 3 is the ultrasonic generator 301, which generates high-frequency vibration energy. Through its connection with the amplitude transformer 302, the ultrasonic generator 301 efficiently converts electrical energy into mechanical vibration energy, which is then transmitted to the clamp shaft 201 via the amplitude transformer 302. As a key component for vibration transmission, the amplitude transformer 302 amplifies the vibration amplitude. This means that the vibration energy output from the ultrasonic generator 301 is enhanced to a certain extent after passing through the amplitude transformer 302, thus acting more effectively on the backlight assembly. Simultaneously, due to the direct connection between the amplitude transformer 302 and the clamp shaft 201, the vibration energy can be directly transmitted to the vibrating head 203 connected to the clamp shaft 201, thereby acting on the backlight assembly. By directly connecting the output of the ultrasonic generator 301 to the amplitude transformer 302, and then having the amplitude transformer 302 transmit the vibration energy to the clamp shaft 201, this compact and direct connection method helps reduce energy loss during vibration transmission. This means that more vibration energy can be directly applied to the backlight assembly, improving optimization efficiency.

[0040] Please refer to Figure 2 In one embodiment, there is one ultrasonic generator 301 and two amplitude transformers 302, which are positioned opposite each other on both sides of the frame 1. The ultrasonic generator 301 is connected to the two amplitude transformers 302. The opposite positioning of the two amplitude transformers 302 on both sides of the frame 1 ensures a more even distribution of vibration energy on the backlight assembly. Since both ends of the clamp shaft 201 are connected to an amplitude transformer 302, the vibration energy generated by the ultrasonic generator 301 can act on both ends of the clamp shaft 201 through the two amplitude transformers 302, avoiding the problem of uneven vibration of the clamp shaft 201 due to unilateral vibration. Furthermore, by designing a single ultrasonic generator 301 to drive the vibration of the two amplitude transformers 302, the electrical signal generated by the single ultrasonic generator 301 is simultaneously distributed to the two amplitude transformers 302. The system structure is relatively simple, the cost is low, and it is easy to control and maintain.

[0041] Please refer to Figure 3In another embodiment, there are two ultrasonic generators 301 and two amplitude transformers 302, which are positioned opposite each other on both sides of the frame 1. Each ultrasonic generator 301 is connected to one of the two amplitude transformers 302. Each ultrasonic generator 301 independently drives one amplitude transformer 302 to generate mechanical vibration. This method provides greater flexibility and independence. It ensures a stable energy supply to each amplitude transformer 302, avoiding uneven energy distribution. Furthermore, the parameters of the two ultrasonic generators 301 can be adjusted separately as needed to optimize the working effect.

[0042] It should be noted that the opposing arrangement of the two amplitude rods 302 not only helps to balance the vibration distribution but also improves the stability of the entire vibration assembly 3. During vibration, the two amplitude rods 302 can support and balance each other, reducing swaying and instability caused by vibration. This stability is crucial for protecting the backlight assembly from damage and improving the optimization effect.

[0043] Furthermore, the vibration assembly 3 also includes a connecting rod 303, with both ends of the connecting rod 303 connected to two amplitude transformers 302 respectively. The connection between the connecting rod 303 and the two amplitude transformers 302 helps to further balance the vibration distribution. The amplitude transformers 302 are an important component of the ultrasonic vibration system, one of their main functions being to transmit and amplify the mechanical vibration generated by the ultrasonic generator 301. Connecting a connecting rod 303 between the two amplitude transformers 302 allows the connecting rod 303 to act as a medium for vibration transmission, ensuring stable and efficient transmission of vibration energy between the two amplitude transformers 302. The design of the amplitude transformers 302 typically includes the function of amplifying mechanical vibration displacement. Through a reasonable design of the amplitude transformers 302 and the connection method of the connecting rod 303, the vibration amplification effect can be further enhanced, making the vibration energy more concentrated and powerful. It should be noted that the connecting rod 303 itself has a certain degree of rigidity, which can resist the influence of external interference and vibration on the system. By increasing the rigidity and strength of the connecting rod 303, the rigidity and stability of the entire vibration system can be further improved, ensuring effective transmission of vibration energy and consistency of processing results.

[0044] Please refer to Figure 2 and Figure 3The amplitude transformer 302 has a first oblong hole 3021 and a second oblong hole 3022. The clamp shaft 201 and the connecting rod 303 pass through the first oblong hole 3021 and the second oblong hole 3022, respectively. The oblong hole design allows the clamp shaft 201 and the connecting rod 303 to be adjusted to a certain extent on the amplitude transformer 302, enabling the vibration assembly 3 to adapt to vehicle backlight assemblies of different sizes and shapes, thus improving the versatility and practicality of the device. Users can adjust the position of the clamp shaft 201 and the connecting rod 303 according to actual needs to ensure that the vibration energy can be accurately applied to the backlight assembly. The oblong hole design also reduces stress concentration on the amplitude transformer 302 caused by the clamp shaft 201 and the connecting rod 303. During vibration, the clamp shaft 201 and the connecting rod 303 are subjected to vibration forces from the amplitude rod 302. The waist-shaped hole can disperse these stresses, reduce the risk of local stress concentration, and thus protect the amplitude rod 302, clamp shaft 201, connecting rod 303 and other components from damage.

[0045] Please refer to Figure 4 The carrier 202 is provided with a plurality of slots 2021 evenly spaced along its width direction, and a vibration head 203 is disposed on the slot 2021. By providing slots 2021 evenly spaced along its width direction on the carrier 202 and equipping each slot with a vibration head, simultaneous multi-point vibration of the backlight assembly is achieved, which improves the uniformity and comprehensiveness of vibration coverage and helps to improve the flatness of the backlight assembly more quickly.

[0046] Specifically, the tank 2021 extends along the length of the carrier 202. Designing the tank 2021 to extend along the length of the carrier 202 makes the vibration trajectory formed by the vibrating head 203 on the backlight assembly more continuous and uniform. This design helps reduce dead zones and blind spots during vibration, improving the utilization rate and optimization effect of vibration energy.

[0047] In this embodiment, the end of the vibrating head 203 facing the frame 1 is circular. The circular design has the characteristics of being smooth and without sharp edges. Designing the end of the vibrating head 203 facing the frame as circular helps to reduce localized impacts and stress concentrations during vibration. At the same time, the circular design has a better ability to disperse vibration energy, making the vibration more uniform and stable, thereby protecting the backlight assembly from damage and improving the optimization effect.

[0048] Please refer to this again. Figure 1Multiple leveling components 4 are provided on the side of the frame 1 away from the vibrating head 203. The leveling components 4 on the side of the frame 1 away from the vibrating head 203 allow the user to adjust the level of the frame 1 according to actual needs, ensuring that the backlight assembly is in a stable horizontal state during optimization, avoiding uneven vibration and poor optimization results caused by the tilt of the frame 1. At the same time, the leveling components 4 also improve the ease of use and operation of the device. In this embodiment, the leveling components 4 are leveling nuts, four of which are located at the four corners of the frame 1.
