Description

Technical Field

[0001] This utility model relates to the field of automotive interior parts processing technology, and in particular to a car roof iron frame folding mechanism. Background Technology

[0002] Car roofs are common interior parts for automobiles. During the manufacturing process of car roofs, their iron frames need to be installed. In order to improve production efficiency, most car roof assembly equipment is equipped with an automatic iron frame folding mechanism.

[0003] A car roof frame automatic folding mechanism and assembly device disclosed in Chinese Patent Publication No. CN214930249U describes a mechanism that automatically folds and assembles a car roof frame. This mechanism uses a piston rod of a drive cylinder to retract and push, causing a hinge-controlled pressure plate to switch between a vertical and folded state. This allows the pressure plate to rotate around a pin, folding the plate and automatically installing the frame onto the roof. However, according to existing car roof frame folding mechanisms and technologies, the prior art uses a hinge connection to control the pressure plate's folding, primarily relying on a lever principle to transmit power. This process involves friction and energy loss. Over time, wear may occur between the hinge pin and hinge hole, increasing the connection gap and affecting the accuracy of the pressure plate's folding angle. This can lead to deviations in the frame's position after folding, making it difficult to guarantee the installation accuracy of the frame and roof, potentially resulting in looseness or excessive tightness. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the prior art, solve the problems mentioned in the background art, and provide a car roof iron frame folding mechanism.

[0005] The purpose of this utility model is achieved through the following technical solution: a car roof iron frame folding mechanism, including a mounting frame and a lifting mechanism for adjusting the height of the mounting frame. A mounting seat is fixedly provided inside the mounting frame. Multiple folding components are provided on the top of the mounting frame. Each folding component includes a mounting plate slidably disposed on the top of the mounting frame. A fixing seat is fixedly provided on one side of the top of the mounting plate. A spline shaft is rotatably disposed on the fixing seat. A pressure block adapted to the folding plate of the iron frame is inserted into the outer surface of the spline shaft. The pressure block is splinedly connected to the spline shaft. A control component for controlling the rotation of the spline shaft is provided on the mounting plate. The control component includes a gear and a rack. The gear is splinedly connected to the spline shaft. The rack is longitudinally disposed inside the gear. A drive component for controlling the synchronous longitudinal sliding of multiple racks is provided inside the mounting frame.

[0006] Preferably, the drive assembly includes a first hydraulic cylinder fixedly mounted on the mounting base, a linkage component fixedly mounted on the output end of the first hydraulic cylinder, and a connecting plate slidably provided laterally for each rack position of the linkage component, with the end of the connecting plate away from the linkage component being fixedly connected to the rack.

[0007] Preferably, a slider is fixedly installed at the bottom of the mounting plate. The slider is T-shaped. The mounting bracket has a groove that matches the slider. A positioning bolt is threaded on the inner side of the mounting plate. The positioning bolt passes through the mounting plate and contacts the mounting bracket.

[0008] Preferably, the fixed base has a rotating hole corresponding to the position of the spline shaft, and the spline shaft is connected to the rotating hole through a bearing.

[0009] Preferably, the mounting plate is fixedly provided with a guide plate at the position corresponding to the rack, the guide plate is rectangular in shape, and the rack is provided with a sliding hole adapted to the guide plate at the position corresponding to the guide plate.

[0010] Preferably, the connecting plate is rectangular in shape, and the linkage component has a slot corresponding to each position of the connecting plate.

[0011] Preferably, the lifting mechanism includes a base, and a second hydraulic cylinder is fixedly installed at each of the four corners of the mounting frame, and the output end of the second hydraulic cylinder is fixedly connected to the bottom of the mounting frame.

[0012] The beneficial effects of this car roof iron frame folding mechanism are as follows: by setting up folding components, control components, and drive components, the gear and rack combination can provide a precise transmission ratio, allowing for precise control of the rotation angle of the spline shaft and pressure block. At the same time, the synchronous operation of multiple control components uses a single power mechanism, which reduces production costs and ensures that the folding action of multiple control components on the iron frame folding plate is consistent, further improving processing accuracy. In addition, the position and model of the pressure block can be quickly adjusted according to requirements, expanding the application range of the folding mechanism. Attached Figure Description

[0022] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" 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 of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0023] Additional aspects and advantages of this invention will be further set forth in the description which follows in conjunction with the accompanying drawings, and in part will be obvious from the description or may be learned by practice of the invention.

[0024] like Figures 1 to 7As shown, a car roof frame folding mechanism includes a mounting frame 1 and a lifting mechanism 2 for adjusting the height of the mounting frame 1. The lifting mechanism 2 includes a base 201, and a second hydraulic cylinder 202 is fixedly installed at each of the four corners of the mounting frame 1. The output end of the second hydraulic cylinder 202 is fixedly connected to the bottom of the mounting frame 1. The height of the mounting frame 1 can be adjusted using the second hydraulic cylinders 202, thus adapting to various working environments. A mounting seat 3 is fixedly installed inside the mounting frame 1, and multiple folding components 4 are provided on the top of the mounting frame 1. The folding component 4 includes a mounting plate 401 slidably installed on the top of the mounting frame 1. A fixed seat 402 is fixedly installed on one side of the top of the mounting plate 401. A splined shaft 403 is rotatably installed on the fixed seat 402. A rotating hole 4021 is opened on the fixed seat 402 corresponding to the position of the splined shaft 403. The splined shaft 403 is connected to the rotating hole 4021 through a bearing. By using the aforementioned bearing, the splined shaft can be reduced in height. The friction during the rotation of the spline shaft 403 improves its stability. A pressure block 404, which is compatible with the folding plate of the iron frame, is inserted into the outer surface of the spline shaft 403. The pressure block 404 is splinedly connected to the spline shaft 403. The mounting plate 401 is equipped with a control component 5 for controlling the rotation of the spline shaft 403. The control component 5 includes a gear 501 and a rack 502. The gear 501 is splinedly connected to the spline shaft 403. The rack 502 is longitudinally arranged inside the gear 501. A guide plate 4013 is fixedly provided on the mounting plate 401 at the position corresponding to the rack 502. The guide plate 4013 is rectangular in shape. A sliding hole 5021, which is compatible with the rack 502, is opened at the position corresponding to the guide plate 4013. By using the guide plate 4013, it can be ensured that the rack 502 always maintains longitudinal sliding and ensures the stability of the meshing between the rack 502 and the gear 501. The interior of the mounting bracket 1 is equipped with a drive component 6 for controlling the synchronous longitudinal sliding of multiple racks 502.

[0025] In summary:

[0026] Firstly, such as Figures 4 to 7 As shown, the control component 5 uses the combination of gear 501 and rack 502. Gear 501 is splinedly connected to spline shaft 403, which can provide a precise transmission ratio, so that the rotation angle of spline shaft 403 can be precisely controlled, ensuring that the pressure block 404 can accurately fold the iron frame plate, improve the installation accuracy of iron frame and canopy, and reduce the problem of loosening or over-tightening caused by inaccurate folding angle.

[0027] Secondly, such as Figures 4 to 7 As shown, the transmission structure of gear 501 and rack 502 has high load-bearing capacity and stability, and can withstand the large force during the folding process of the iron frame. It is not easy to deform or be damaged. At the same time, the guide plate 4013 set on the mounting plate 401 ensures the stability of the longitudinal sliding of rack 502, further improving the reliability of the entire transmission system.

[0028] like Figures 2 to 6 As shown, the drive assembly 6 includes a first hydraulic cylinder 601 fixedly mounted on the mounting base 3. A linkage 602 is fixedly mounted on the output end of the first hydraulic cylinder 601. A connecting plate 603 is laterally slidably provided on the linkage 602 corresponding to the position of each rack 502. The end of the connecting plate 603 away from the linkage 602 is fixedly connected to the rack 502. The shape of the connecting plate 603 is rectangular. A slot 6021 adapted to each connecting plate 603 is opened on the linkage 602 corresponding to the position of each connecting plate 603. By using the provided slot 6021, the linkage 602 can drive multiple connecting plates 603 to rise or fall. At the same time, when the position of the control component 5 changes, the slot 6021 and the connecting plate 603 can continue to cooperate, so as to ensure that the drive assembly 6 controls multiple control components 5 to operate synchronously, thus ensuring the stability and consistency of the processing process.

[0029] In summary, the drive assembly 6, through the linkage 602 and the connecting plate 603, can control multiple control assemblies 5 to operate synchronously, ensuring that the folding actions of the multiple control assemblies 5 on the iron frame folding plate are consistent, avoiding the iron frame installation deviation caused by asynchrony, and further improving the processing accuracy.

[0030] like Figures 5 to 7 As shown, a slider 4011 is fixedly installed on the bottom of the mounting plate 401. The slider 4011 is T-shaped. The mounting bracket 1 has a groove 101 that matches the slider 4011. The inner side of the mounting plate 401 is threaded with a positioning bolt 4012. The positioning bolt 4012 passes through the mounting plate 401 and contacts the mounting bracket 1. The mounting plate 401 can slide on the top of the mounting bracket 1, and the pressure block 404 is splinedly connected to the spline shaft 403. This allows the position of the mounting plate 401 to be flexibly slid according to the position and width of the iron frame folding plate (after adjustment, it can be limited by the positioning bolt 4012), and the corresponding pressure block 404 can be replaced, thereby adapting to the processing needs of iron frames of different sizes and shapes and expanding the application range of the folding mechanism.

[0031] The work process is as follows:

[0032] S1: In use, the linkage 602 is moved upward by the first hydraulic cylinder 601, and then the cooperation between the connecting plate 603 and the slot 6021 can be used to make multiple connecting plates 603 drive multiple racks 502 to slide upward synchronously.

[0033] S2: When the rack 502 slides upward, the gear 501 will rotate. Then, by using the spline connection between the gear 501 and the spline shaft 403, the spline shaft 403 can control the pressure block 404 to flip outward from the mounting frame 1, thereby folding the iron frame plate.

[0034] S3: After the folding is completed, the linkage 602 is controlled to slide downward by the first hydraulic cylinder 601. Then, by utilizing the cooperation between the connecting plate 603 and the slot 6021, multiple connecting plates 603 can drive multiple racks 502 to slide downward synchronously.

[0035] S4: When the rack 502 slides downward, the gear 501 will rotate. Then, by using the spline connection between the gear 501 and the spline shaft 403, the spline shaft 403 can control the pressure block 404 to flip into the mounting bracket 1, so that the pressure block 404 returns to the vertical state.

[0036] The first hydraulic cylinder 601, the second hydraulic cylinder 202, the iron frame of the car roof, and the pressure block 404 described in this application are all known technologies in this field, and therefore their specific structures and working principles are not described in detail.

[0037] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
