Description

Technical Field

[0001] The invention relates to the field of automobile accessory products, and in particular to an automobile self-adaptive reflective heat-insulating device. Background Art

[0002] In the hot summer, when a car is parked in the strong sun, the temperature inside the car rises quickly, the steering wheel is hot, the seats are hot, and the instrument panel and the plastic or leather materials inside the car will emit an unpleasant odor under high temperature, which not only damages the vehicle, but also the physical and mental health of the driver and passengers. In the cold winter, the temperature inside the car will also drop sharply with the external environment, and the car will lack the insulation effect for a period of time.

[0003] To solve this problem, many inventors have come up with many ways, some of which are solved outside the car, and some are solved inside the car, but in summary, they all have some fatal shortcomings and are difficult to be accepted by users. For example, the problems encountered when solving the problem outside the car are difficult to overcome, and the influence of dust and weather (such as wind, rain, snow) makes it difficult to fold and unfold, and there are also human damage and theft. Solving the problem inside the car has the disadvantages of occupying a certain space, being troublesome to operate, and having poor results.

[0004] In publication number CN107444079A, a pleated reflective heat-insulating curtain for in-vehicle use is disclosed, comprising a pleated fabric, which has the same shape as the vehicle body glass when unfolded; the pleated fabric is arranged in the vehicle body near the vehicle window glass, with one side fixed to the vehicle body and the other side movably hung on the vehicle body; elastic bands are connected between the two sides, and a reflective film is coated on the side of the pleated fabric near the vehicle body glass.

[0005] The above utility model patent also has the following defects: 1. The main body of the pleated reflective insulation curtain inside the car affects the driver's line of sight within a certain angle during driving, making it impossible for the driver to clearly observe whether there are any obstacles outside the car; 2. The folding process of the pleated fabric requires manual operation by the owner, which increases the time for parking and starting the car; 3. After the pleated fabric, elastic band and reflective film are folded for a long time, the heat insulation or thermal insulation effect of the entire pleated reflective insulation curtain inside the car is affected, and at the same time, the size of the effective use space of the vehicle is affected. Summary of the invention

[0006] The purpose of the present invention is to provide an automobile heat insulation device that can be automatically folded and unfolded, which solves the problem that traditional automobile sunshade devices can only block sunlight but cannot isolate heat transfer and have poor heat preservation effect in high or low temperature environments.

[0007] The adaptive automobile thermal insulation device proposed in the present invention includes a slide rail and a telescopic block. The two slide rails are connected by multiple telescopic blocks to form a thermal insulation layer. The track shape of the slide rail can be bent and changed arbitrarily to match the change of the geometric shape of the thermal insulation part covered by the telescopic block. The telescopic blocks are connected by hinges.

[0008] The use principle of the present invention is that the present invention is a functional device that mainly solves the problem of heat insulation and heat preservation in the space inside the car window when the external environment temperature is high or low. It can also be applied to other structures or devices that require heat insulation and heat preservation in similar climatic environments. First, the fixed form of the slide rail structure determines the shape and area covered by the telescopic block; then, in order to reduce the number of steps for the owner to manually operate the insulation device, the slide rail and the telescopic block are used to cooperate in blocking sunlight and isolating heat transfer; finally, the hinges arranged between the telescopic blocks ensure that the folding or unfolding of the entire thermal insulation device can be controlled by controlling the movement of one telescopic block.

[0009] The beneficial effect of the adaptive automobile thermal insulation device of the present invention is that the thermal insulation device has a simple structure, and the process of folding and storing or opening and using does not require too much manual operation, so the whole use process is very convenient. It can also prevent the car owner from increasing the time of parking or starting the car due to excessive temperature changes in the car when parking for a short time, and the time of unfolding and folding the sunshade and heat insulation device is too long. Due to the installation of the heat insulation device in the existing car, the heat insulation device is stored after being folded, which affects the reasonable use of the interior space of the car. The present invention also eliminates the unnecessary troubles caused to the car owner by this adverse effect. It makes the sunshade, heat insulation and heat insulation of the interior environment of the car more convenient. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The structure of the adaptive automobile thermal insulation device of the present invention is further described below in conjunction with the accompanying drawings and specific embodiments.

[0022] In order to achieve the convenience of the adaptive automobile thermal insulation device in this embodiment, the entire automobile thermal insulation device is controlled by a motor at the end of the traction belt 7 or the traction rope 10 to unfold upward or fold downward, thereby reducing the manual operation time. At the same time, the thermal insulation device of the present invention can be applied to other fields according to different occasions where the slide rail is set, so as to achieve the effect of thermal insulation in similar climate environments.

[0023] like Figure 1 , 2 As shown in Figures 3, 4, 5, 6, 7, 8, 9 and 10, the adaptive automobile thermal insulation device proposed by the present invention includes a slide rail 1 and a telescopic block 2. The two slide rails 1 are connected by multiple telescopic blocks 2 to form a thermal insulation layer. The track shape of the slide rail 1 can be arbitrarily bent and changed to match the change of the geometric shape of the thermal insulation part covered by the telescopic block 2. The telescopic blocks 2 are connected by hinges.

[0024] The use principle of the present invention is that the present invention is a functional device that mainly solves the problem of heat insulation and heat preservation in the space inside the car window glass when the external ambient temperature is high or low. It can also be applied to other structures or devices that require heat insulation and heat preservation in similar climatic environments. First, the fixed form of the slide rail 1 structure determines the shape and area covered by the telescopic block 2; then, in order to reduce the number of steps for the owner to manually operate the insulation device, the slide rail 1 and the telescopic block 2 are used to cooperate in blocking sunlight and isolating heat transfer; finally, the hinges arranged between the telescopic blocks 2 ensure that the folding or unfolding of the entire thermal insulation device can be controlled by controlling the movement of one telescopic block 2.

[0025] The slide rail 1 is arranged on the A-pillars on both sides of the cab instrument panel 14 and inside the cab instrument panel 14. The top of the slide rail 1 starts from the two sides of the top of the windshield, and the bottom of the slide rail 1 ends at the two sides inside the cab instrument panel 14. The telescopic block 2 includes a stretching part 3 and a fixing part 4. The stretching part 3 and the fixing part 4 are connected in a drawer-like manner at both ends. The two ends of the telescopic block 2 are connected to the slide rail 1 through a latch 6. The moving direction and covering position of the telescopic block 2 are determined by the guidance of the slide rail 1. The latch 6 of the first telescopic block 2 at the top is connected to the traction belt 7. The bottom end of the slide rail 1 is provided with a telescopic block container 8 inside the cab instrument panel 14. First, the fixed position of the slide rail 1 structure, the fixed starting point is inside the A-pillars on both sides of the front row of windows, and similarly, it can also be outside the A-pillars, but the closer the starting point is to the top of the A-pillar, the smaller the gap left for the top of the car's front window glass, and the better the heat insulation effect of the entire heat insulation device; secondly, in order to reduce the steps of the owner's manual operation of the heat insulation device, the slide rail 1 and the telescopic block 2 are used to block sunlight and isolate heat transfer; then, to ensure the shielding and sealing effect of the telescopic block 2 on the car's front window cab, the tensile part 3 and the fixed part 4 cooperate with the spring 5 to achieve the sealing effect of blocking sunlight and isolating heat transfer; finally, considering the convenience and simplicity of folding the entire heat insulation device, a telescopic block container 8 is set in the cab instrument panel 14 at the bottom of the front window glass, that is, the bottom end of the slide rail 1. The structure of the heat insulation device is simple, and the process of folding and storing or opening for use does not require too much manual operation, so the entire use process is very convenient.

[0026] The slide rail 1 is arranged on both sides of the roof frame and the front windshield of the car. The telescopic block 2 includes a stretching part 3 and a fixing part 4. The stretching part 3 and the fixing part 4 are connected in a drawer-like manner at both ends. A spring 5 can also be arranged at the connecting part to achieve a better effect of folding and unfolding the telescopic block 2. The two ends of the telescopic block 2 are connected to the slide rail 1 through a clip 6. The telescopic block 2 on the slide rail 1 is powered by a motor. The appearance of the fixing part 4 matches the curvature of the appearance of the top of the car and the outer surface of the front window glass. The telescopic block 2 slides back and forth in the slide rail 1 to cover the front windshield of the car, or folds and moves to the top of the car, which will not block the line of sight of the owner driving the car. At the same time, the movement of the telescopic block 2 is all controlled by a motor, which solves the problem that the unfolding and folding process requires manual operation by the owner, which increases the length of time for parking and starting the car. The entire thermal insulation device is arranged outside the car and will not affect the size of the effective use space of the vehicle.

[0027] The slide rail 1 is provided inside the door window frame and inside the door below the lower frame of the door glass. The top of the slide rail 1 starts from both sides of the top of the door window frame, and the bottom of the slide rail 1 stops at both sides of the door inner panel. The telescopic block 2 includes a stretching portion 3 and a fixing portion 4. The stretching portion 3 and the fixing portion 4 are connected in a drawer-like manner at both ends. The two ends of the telescopic block 2 are connected to the slide rail 1 through a clip 6. The moving direction and covering position of the telescopic block 2 are determined by the guidance of the slide rail 1. The clip 6 is connected to the traction belt 7. The bottom of the slide rail 1 is provided with a telescopic block container 8 at the door inner panel below the lower frame of the door glass. The purpose of this design is to ensure that the thermal insulation device is set at the side windshield position of the car, which will not affect the opening and closing of the car door, and at the same time, it can achieve the effect of thermal insulation and heat insulation for the side windshield position of the car door.

[0028] The hinge angle between the telescopic blocks 2 is less than or equal to 180 degrees. The multiple telescopic blocks 2 are connected by hinges. In order to facilitate the expansion or folding of the telescopic blocks 2 of the thermal insulation device, the hinge angle is set to be less than or equal to 180 degrees, ensuring that the telescopic blocks 2 are stacked in order when they are folded back into the telescopic block 2 container. The folding occupies a small space inside the cab instrument panel 14, which does not affect the overall parts layout of the car.

[0029] The traction belt 7 uses a unidirectional traction method of pulling up the latch 6. The purpose of using only a unidirectional upward expansion of the telescopic block 2 is that when the thermal insulation device is expanded upward, force must be used for traction to achieve the expansion of the entire thermal insulation device. When the entire thermal insulation device is folded downward, the friction between the latch 6 and the slide rail 1 can be reduced, so that the inclination between the slide rail 1 and the telescopic block 2 produces an automatic folding effect, reducing the power traction required for downward folding, thereby saving energy.

[0030] The slide rail 1 is provided with a slide groove 9 for sliding with the catch 6, the shape of the slide groove 9 is U-shaped, and the shape of the catch 6 is spherical or square. The shape of the slide groove 9 and the shape of the catch 6 provided in the slide rail 1 cooperate with each other to restrict each other, so that the telescopic block 2 can slide up and down in the slide rail 1, and can also ensure that the telescopic block 2 will not deviate from the track of the slide rail 1.

[0031] The slide rail 1 can also be designed to be cylindrical, and the latch 6 is spherical or cylindrical. When an opening is provided on the inner side of the slide rail 1, the latch 6 of the first telescopic block 2 at the top is connected to the traction belt 7 just above. When openings are provided on both the inner and outer sides of the slide rail 1, the outer side of the latch 6 of the first telescopic block 2 at the top is connected to the traction belt 7.

[0032] The traction belt 7 adopts a bidirectional traction mode that can be pulled up and folded to the telescopic block 2, and the clip 6 of the first telescopic block at the top of the entire adaptive automobile thermal insulation device is rotatably connected to the traction belt 7. The bidirectional traction mode that can be pulled up and folded to the telescopic block 2 improves the quickness of the entire thermal insulation device to be unfolded or folded, and adapts to automobile A-pillars with different inclinations; the purpose of the rotatable connection between the clip 6 and the traction belt 7 is to facilitate the convenience of unfolding and folding the telescopic block 2.

[0033] The connecting part of the fixing part 4 between the telescopic blocks 2 is provided with a collar 13, and the collars 13 are connected by a traction rope 10, and the fixing point of the traction rope 10 is at the top telescopic block 2. The design of this structure is to facilitate better control of the stacking order of the telescopic blocks 2 in the telescopic block container 8 when the telescopic blocks 2 are folded, to prevent the telescopic blocks 2 from being stacked in a disorderly manner, and to affect the folding effect of the entire automobile thermal insulation device. Therefore, during the folding process, it is only necessary to control the top telescopic block 2 to fold downward, and the front telescopic blocks 2 are automatically stacked neatly.

[0034] One or more rings 13 are provided at the middle fixed part 4 of each telescopic block 2. The adaptive automobile thermal insulation device with one ring 13 uses a traction rope 10 to pass through the ring 13 and fold downward to fold the telescopic block 2. The adaptive automobile thermal insulation device with multiple rings 13 uses a corresponding number of traction ropes 10 to pass through the rings 13 at corresponding positions and fold the telescopic block 2 together. In the above structure, in order to better control the stacking order of the telescopic blocks 2 in the telescopic block container 8, it is only necessary to control the rings 13 connected between the two telescopic blocks 2 to achieve the actual effect. The same method of multiple traction ropes 10 and multiple rings 13 can achieve the same effect.

[0035] The slide rail 1 is arranged inside the door window frame and inside the door below the lower frame of the door glass. The top of the slide rail 1 starts from both sides of the top of the door window frame, and the bottom of the slide rail 1 ends at both sides of the door inner panel. The telescopic block 2 includes a stretching portion 3 and a fixing portion 4. The stretching portion 3 and the fixing portion 4 are connected in a drawer-like manner at both ends. The two ends of the telescopic block 2 are connected to the slide rail 1 through a snap 6. The moving direction and covering position of the telescopic block 2 are determined by the guidance of the slide rail 1. The snap 6 is connected to the traction belt 7. The expansion and storage methods are divided into two types according to the traction method of the traction belt 7: first, the traction belt 7 uses a unidirectional upward pull-up method of the snap 6 to pull the whole upward to expand the adaptive car The heat preservation and heat insulation device, the traction rope 10 uses a downward traction method to store the adaptive automobile heat preservation and heat insulation device as a whole downward to below the lower frame of the door glass, the fixing point of the traction rope 10 is in the middle of the telescopic block 2 at the bottom, and the clip of the first telescopic block 2 at the top of the entire adaptive automobile heat preservation and heat insulation device is rotatably connected with the traction belt 7; secondly, the traction belt 7 adopts a bidirectional traction method that can pull up and store the telescopic block 2, and the adaptive automobile heat preservation and heat insulation device is pulled up and unfolded as a whole or stored downward as a whole to below the lower frame of the door glass, and the clip 6 of the first telescopic block 2 at the top of the entire adaptive automobile heat preservation and heat insulation device is rotatably connected with the traction belt 7. The setting of this structure ensures that the side windshield of the car can also be protected by the heat preservation and heat insulation device, and further ensures the heat preservation and heat insulation effect of the car.

[0036] A conveying mechanism 15 is provided inside the slide rail 1. The conveying mechanism 15 includes a conveyor belt and a two-way ratchet. The two-way ratchet is arranged at both ends of the conveyor belt, and the telescopic block 2 is arranged on the conveyor belt. The telescopic block 2 is conveyed back and forth between the roof and the outside of the front window glass through the conveying mechanism 15, ensuring that when the telescopic block 2 is used to block the front window glass of the car, it can quickly block the sunlight and isolate the heat transferred from the outside of the front window glass to the inside of the car, and also play a role in heat preservation and heat insulation; when the car is driving, if it is necessary to avoid blocking the owner's line of sight, the conveying mechanism 15 directly transfers the telescopic block 2 to the roof of the car; reducing the process of manual operation to unfold the heat preservation and heat insulation device, greatly improving the convenience of the owner to operate the heat preservation and heat insulation device.

[0037] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
