Description

Technical Field

[0001] This application relates to the field of sunshades, and particularly to an extendable and retractable car sunshade. Background Art

[0002] Car sunshades are mainly used to block direct sunlight into the car, and they can effectively reduce the temperature inside the car. In the hot summer, direct sunlight exposure will cause the temperature inside the car to rise rapidly. Using a sunshade can reduce the entry of sunlight heat and keep the environment inside the car relatively cool. For example, in high-temperature weather, without a sunshade, the temperature inside the car may rise above 60 degrees Celsius, while with a sunshade, the temperature can be reduced by 10 - 20 degrees Celsius.

[0003] There are also various types of car sunshades. Common ones include magnetic type; suction cup type; hook type, etc. The magnetic sunshade is adsorbed on the window frame through magnets, which is convenient and firm to install; the suction cup type relies on suction cups for fixation and is suitable for most windows; the hook type needs to be hung on the hook at the top of the window, with good stability.

[0004] Currently, the sunshades on the market generally have the problems that the storage space occupied is large and it affects the driver's line of sight. Secondly, most sunshades need to be customized according to the vehicle model and need to be manually unfolded to block sunlight, with cumbersome operations and being not conducive to promotion. In view of this, we propose an extendable and retractable car sunshade to solve the above problems. Utility Model Content

[0005] The purpose of this application is to reduce the storage space of the sunshade and avoid affecting the driver's line of sight. Secondly, it can improve the convenience of operation. Compared with the prior art, an extendable and retractable car sunshade is provided, including a base. One end of the base is rotatably connected to a mounting plate. A driving component is arranged on the bottom wall of the mounting plate. Both the left and right ends of the driving component are rotatably connected to a transverse telescopic component. A longitudinal telescopic component is fixedly connected to the side of the transverse telescopic component close to the base. A folding curtain is arranged inside the transverse telescopic component. The upper end of the folding curtain is fixedly connected to a traction component. A wire harness component is arranged at the bottom of the transverse telescopic component. The wire harness component includes a wire winding ring fixedly connected to the bottom of the transverse telescopic component. A traction wire harness is wound around the wire winding ring. Both the left and right ends of the traction wire harness longitudinally pass through the folding curtain in sequence and are connected to the traction component. The folding curtain is used to block sunlight and reduce the temperature inside the car. Through the longitudinal telescopic component, the unfolded folding curtain is folded downwards. In cooperation with the driving component, the transverse telescopic component is controlled to converge from both sides to the middle, so that the folding curtain is folded multiple times, reducing the occupied space. The whole process is automatically controlled by the device without manual interference, improving the convenience of operation.

[0006] Further, the driving component includes a second motor fixedly connected to the bottom wall of the mounting plate. A second lead screw is provided on a side wall of the mounting plate close to the base. A group of limit blocks corresponding to the upper and lower ends of the second lead screw are fixedly connected to the side wall of the mounting plate. The upper end of the second lead screw is rotatably connected to the upper limit block, and the lower end of the second lead screw passes through the lower limit block and is rotatably connected. The lower end of the second lead screw is meshed and connected to the output end of the second motor through a second gear set. A second slider is threadedly connected to the outside of the second lead screw. The side wall of the second slider away from the base is rotatably connected to the transverse telescopic component through a connecting rod. The second motor rotates in cooperation with the second gear set to make the second lead screw rotate, so that the second slider moves along the second lead screw, and the second slider controls the extension and retraction of the transverse telescopic component.

[0007] Further, the transverse telescopic component includes a first receiving beam rotatably connected to the inner wall of the mounting plate. One end of the first receiving beam close to the mounting plate is rotatably connected to the connecting rod. The other end of the first receiving beam away from the mounting plate is meshed and connected to a second receiving beam through a gear disc. The other end of the second receiving beam away from the first receiving beam is also meshed and connected to a third receiving beam through a gear disc. The other end of the third receiving beam away from the second receiving beam is also meshed and connected to a fourth receiving beam through a gear disc. A first support beam is rotatably connected to the side of the first receiving beam close to the base. A first reserved groove is provided at one end of the first support beam away from the mounting plate. A first short beam is slidably connected inside the first reserved groove. One end of the first short beam away from the first receiving beam is rotatably connected to the second receiving beam. One end of the second receiving beam close to the base and away from the first receiving beam is rotatably connected to the third receiving beam through a bent beam. A second support beam is rotatably connected to the side wall of the fourth receiving beam close to the base. A second reserved groove is provided at one end of the second support beam close to the mounting plate. A second short beam is slidably connected inside the second reserved groove. One end of the second short beam away from the fourth receiving beam is rotatably connected to the third receiving beam. A third support beam is rotatably connected to the inner wall of the side of the mounting plate away from the base. The third support beam is rotatably connected to a fourth support beam through a first bending beam. The first bending beam is rotatably connected to the first receiving beam and the second receiving beam through a rotating shaft respectively. One end of the fourth support beam away from the mounting plate is rotatably connected to a fifth support beam through a second bending beam. The second bending beam is also rotatably connected to the third receiving beam and the second receiving beam through a rotating shaft respectively. One end of the fifth support beam away from the second bending beam is rotatably connected to the fourth receiving beam through a third bending beam. The driving component drives the connecting rod to rotate, so that the first receiving beam rotates upward, thereby sequentially driving the second receiving beam, the third receiving beam and the fourth receiving beam to rotate and close inward. The first support beam, the bent beam and the second support beam can improve the stability of the overall structure. The linkage structure composed of the third support beam, the first bending beam, the fourth support beam, the second bending beam, the fifth support beam and the third bending beam can make the first receiving beam, the second receiving beam, the third receiving beam and the fourth receiving beam fold and retract along a predetermined path, improving the stability of the device.

[0008] Further, the longitudinal telescopic component is fixedly connected to the side wall of the second storage beam away from the base. The longitudinal telescopic component includes an installation box. Inside the installation box, a first lead screw is rotatably connected. One end of the first lead screw close to the base penetrates through the installation box and extends to the outside thereof. A first motor is fixedly connected to the lower end of the installation box. The output end of the first motor is meshed and connected to the first lead screw through a first gear set. A first slider is threadedly connected to the outside of the first lead screw. A folding rod is rotatably connected to the inner wall of the longitudinal telescopic component. The lower end of the folding rod away from the first motor is rotatably connected to the inner wall of the longitudinal telescopic component. The lower end of the folding rod close to the first lead screw is rotatably connected to the first slider. The first motor cooperates with the first gear set to rotate the first lead screw, driving the first slider to move along the first lead screw, thereby controlling the extension and folding of the folding rod.

[0009] Further, the traction component includes a pair of first traction beams, which are rotatably connected between the pair of first traction beams through a second hinge. One end of the first traction beam away from the second hinge is rotatably connected to a redundant beam through a first hinge. One end of the redundant beam away from the first traction beam is also rotatably connected to a second traction beam through a first hinge. The upper end of the folding rod is rotatably connected to the second hinge. The up and down movement of the traction component is controlled by the extension and folding of the folding rod. Through the cooperation between the first traction beam and the second traction beam through the second hinge, the first hinge and the redundant beam, the traction component can be folded together with the lateral telescopic component. The redundant beam can provide enough folding space for the folding curtain, avoiding tearing of the folding curtain during the folding process. The traction component can drive the folding curtain to extend upward to block sunlight, and at the same time improve the flatness and stability of the folding curtain in the unfolded state.

[0010] Further, the wire take-up ring is fixedly connected to the lower end of the second storage beam. The left and right ends of the traction wire harness respectively pass upward through the second storage beam and the third storage beam and penetrate through the folding curtain. One end of the traction wire harness away from the wire take-up ring respectively penetrates through the first traction beam and is fixedly connected to the lower end of the second traction beam. The traction wire harness passing through the whole folding curtain can improve the flatness and stability of the folding curtain in the unfolded state, avoiding wrinkles on the folding curtain.

[0011] Compared with the prior art, the advantages of this application are as follows:

[0012] 1. The folding curtain is used to block sunlight and reduce the temperature inside the vehicle. The unfolded folding curtain is folded downward through the longitudinal telescopic component, and the driving component is used to control the lateral telescopic component to close in from both sides to the middle, so that the folding curtain is folded multiple times, reducing the occupied space. The whole process is automatically controlled by the device without manual interference, improving the operation convenience. BRIEF DESCRIPTION OF THE DRAWINGS
