Description

Technical Field

[0001] This utility model relates to the field of sunshade technology, and in particular to a car rear window sunshade. Background Technology

[0002] Car sunshades are used to block outside sunlight and reduce direct sunlight into the car interior, which can lower the temperature inside the car to some extent. Sunshade in the car interior is a major problem for car owners in the summer. Currently, sunshades on the market are all made of sunshade curtains. Existing sunshades cannot be folded and stored when in use, so a whole sunshade curtain takes up a lot of space when not in use. Therefore, we propose a rear window sunshade for cars to solve the above problems. Utility Model Content

[0003] The purpose of this utility model is to address the shortcomings of the prior art by proposing a car rear window sunshade.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a car rear window sunshade, comprising: a sunshade, a sleeve, a metal frame, a first frame, a second frame, a rotating groove, a shaft hole, an inner cavity, a spring, a positioning groove, a limiting groove, a rotating seat, a rotating rod, a limiting block, a suction nozzle, a Velcro surface, and a Velcro hook surface. The sunshade has a sleeve at its edge, and a metal frame is located inside the sleeve. The metal frame is composed of a first frame and a second frame. A rotating groove is located at the tail end of each first frame. Shaft holes are located at the top and bottom of each rotating groove, and an inner cavity is located inside each shaft hole. A spring is located on the inner wall of each inner cavity. The innermost side of the inner cavity is provided with a positioning groove, and limit grooves are provided on both sides of the positioning groove. The two tail ends of the frame are provided with rotating seats, and the rotating seats are located inside the rotating grooves. Rotating rods are provided above and below the rotating seats, and the rotating rods extend rotatably into the inner cavity through shaft holes. The tail ends of the rotating rods are rotatably connected to the positioning grooves, and the outer walls of the rotating rods are fixedly connected to the spring. Limit blocks are provided on both sides of the tail ends of the rotating rods, and the limit blocks are located inside the limit grooves. The front sides of the sunshade are provided with a Velcro surface and a Velcro hook surface, respectively. The back sides of the sunshade are provided with suction nozzles.

[0005] Preferably, the first frame and the second frame are arranged in a symmetrical structure, and the hook and loop surface and the hook and loop surface are arranged in a symmetrical structure.

[0006] Preferably, the limiting block and the limiting groove are rotating structures, and the limiting block can rotate up to 90°.

[0007] Preferably, there are four suction nozzles, and the four suction nozzles are arranged in a symmetrical pairwise structure.

[0008] Preferably, the sunshade is made of polyester fabric, and the upper surface of the polyester fabric is provided with a graphene fiber fabric layer, and the lower surface of the polyester fabric is provided with a negative ion fiber fabric layer.

[0009] Compared with the prior art, this utility model has the following advantages:

[0010] (1) By folding the metal frame, frame one and frame two are folded together, causing the rotating seat to rotate inside the rotating groove. The rotating seat can synchronously drive the rotating rod to rotate in the inner cavity, and the rotating rod can synchronously drive the spring to retract, thus completing the folding and storage of the sunshade. The Velcro hook and loop side are glued together to fix the folded sunshade and prevent it from popping open. When the sunshade needs to be opened, the Velcro hook side is detached from the Velcro loop side, and the outward tension of the spring can synchronously drive the rotating rod to rotate. The rotating rod can synchronously drive the rotating seat to rotate, so that frame one and frame two are folded open, allowing the sunshade to be opened. This makes the sunshade easy to fold and open.

[0011] (2) The end of the rotating rod can rotate synchronously inside the positioning groove. At the same time, the rotating rod can drive the limiting block to rotate synchronously inside the limiting groove, so that the rotating block can rotate up to 90° within the limiting groove. This can limit the folding angle and opening angle between frame one and frame two, and thus limit the folding angle and opening angle of the sunshade simultaneously. Attached Figure Description

[0022] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0023] like Figure 1-9 The car rear window sunshade shown includes: a sunshade 1, a sleeve 2, a metal frame 3, a first frame 4, a second frame 5, a rotating groove 6, a shaft hole 7, an inner cavity 8, a spring 9, a positioning groove 10, a limiting groove 11, a rotating seat 12, a rotating rod 13, a limiting block 14, a suction nozzle 15, a Velcro surface 16, and a Velcro hook surface 17. The sleeve 2 is provided at the edge of the sunshade 1, and the metal frame 3 is provided inside the sleeve 2. The metal frame 3 is composed of the first frame 4 and the second frame 5. The rear end of the first frame 4 is provided with a rotating groove 6. Shaft holes 7 are provided at the top and bottom of the rotating groove 6. An inner cavity 8 is provided inside each shaft hole 7. A spring 9 is provided on the inner wall of each inner cavity 8. The innermost side is provided with a positioning groove 10, and the two sides of the positioning groove 10 are provided with limit grooves 11. The tail end of the frame 2 5 is provided with a rotating seat 12, and the rotating seat 12 is located inside the rotating groove 6. The rotating seat 12 is provided with a rotating rod 13 above and below, and the rotating rod 13 extends rotatably into the inner cavity 8 through the shaft hole 7. The tail end of the rotating rod 13 is rotatably connected to the positioning groove 10, and the outer wall of the rotating rod 13 is fixedly connected to the spring 9. The two sides of the tail end of the rotating rod 13 are provided with limit blocks 14, and the limit blocks 14 are located inside the limit groove 11. The front sides of the sunshade 1 are provided with a hook and loop fastener 16 and a hook and loop fastener 17, respectively. The back sides of the sunshade 1 are provided with suction nozzles 15.

[0024] In this embodiment, frame 1 4 and frame 2 5 are arranged in a symmetrical structure, and the hook and loop surface 16 and the hook and loop surface 17 are arranged in a symmetrical structure.

[0025] In practical use, by folding the metal frame 3, the frame 4 and the frame 5 are folded together, causing the rotating seat 12 to rotate inside the rotating groove 6. The rotating seat 12 can simultaneously drive the rotating rod 13 to rotate in the inner cavity 8, and the rotating rod 13 can simultaneously drive the spring 9 to retract, thus completing the folding and storage of the sunshade 1. The Velcro surface 16 and the Velcro hook surface 17 are glued together to fix the folded sunshade 1 and prevent it from popping open. When it is necessary to open the sunshade 1, the Velcro surface 16 is detached from the Velcro hook surface 17, and then the outward tension of the spring 9 can simultaneously drive the rotating rod 13 to rotate. The rotating rod 13 can simultaneously drive the rotating seat 13 to rotate, causing the frame 4 and the frame 5 to fold open, allowing the sunshade 1 to be opened. This makes the sunshade 1 easy to fold and easy to open.

[0026] In this embodiment, the limiting block 14 and the limiting groove 11 are rotating structures, and the limiting block 14 can rotate up to 90°.

[0027] In practical use, the tail end of the rotating rod 13 can rotate synchronously inside the positioning groove 10. At the same time, the rotating rod 13 can synchronously drive the limiting block 14 to rotate inside the limiting groove 11, so that the rotating block 14 can rotate up to 90° inside the limiting groove 11. This can limit the folding angle and opening angle between frame 1 4 and frame 2 5, and thus simultaneously limit the folding angle and opening angle of the sunshade 1.

[0028] In this embodiment, four suction nozzles 15 are provided, and the four suction nozzles 15 are arranged in a symmetrical structure in pairs.

[0029] In practical use, the suction force of the nozzle 15 can be used to attach the sunshade 1 to the rear window of the vehicle, thereby fixing the sunshade 1.

[0030] In this embodiment, the sunshade curtain 1 is made of polyester fabric layer 101, and the upper surface of the polyester fabric layer 101 is provided with graphene fiber fabric layer 102, and the lower surface of the polyester fabric layer 101 is provided with negative ion fiber fabric layer 103.

[0031] In practical use, the graphene fiber cloth layer 102 and the thermal conductivity of graphene material enable the sunshade curtain 1 to have heat insulation and UV protection functions; the negative ion fiber cloth layer 103 can release negative ions to improve the air quality in the environment and has the function of cleaning the air.

[0032] The working principle of a car rear window sunshade mentioned in this utility model is as follows:

[0033] In use, the sunshade 1 can be attached to the rear window of the vehicle by the suction force of the suction nozzle 15, thus fixing the sunshade 1.

[0034] By folding the metal frame 3, frame 4 and frame 5 are folded together, causing the rotating seat 12 to rotate inside the rotating groove 6. The rotating seat 12 can simultaneously drive the rotating rod 13 to rotate in the inner cavity 8. The rotating rod 13 can simultaneously drive the spring 9 to retract, thus completing the folding and storage of the sunshade 1. The Velcro surface 16 and the Velcro hook surface 17 are glued together to fix the folded sunshade 1 and prevent it from popping open. When it is necessary to open the sunshade 1, the Velcro surface 16 is detached from the Velcro hook surface 17. Then, the outward tension of the spring 9 can simultaneously drive the rotating rod 13 to rotate. The rotating rod 13 can simultaneously drive the rotating seat 13 to rotate, causing frame 4 and frame 5 to fold open, allowing the sunshade 1 to be opened. This makes the sunshade 1 easy to fold and easy to open.

[0035] Meanwhile, the end of the rotating rod 13 can rotate synchronously inside the positioning groove 10, and the rotating rod 13 can synchronously drive the limiting block 14 to rotate inside the limiting groove 11, so that the rotating block 14 can rotate up to 90° inside the limiting groove 11, thereby limiting the folding angle and opening angle between frame 1 4 and frame 2 5, and thus simultaneously limiting the folding angle and opening angle of the sunshade 1.

[0036] Meanwhile, through the graphene fiber cloth layer 102 and the thermal conductivity of graphene material, the sunshade curtain 1 can have heat insulation and UV protection functions; through the negative ion fiber cloth layer 103, negative ions can be released to improve the air quality in the environment, thus having the function of cleaning the air.

[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 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. The scope of protection of this utility model is defined by the appended claims and their equivalents.
