[0002] The damage of high temperature environment to electronic equipment is obvious, and dashcams are no exception. The temperature inside the car may be extremely high in summer, and long-term high temperature exposure will cause damage to the internal components of the dashcam, affecting its normal operation and service life. Through sun protection measures, the temperature of the dashcam can be effectively reduced, reducing the failure rate caused by high temperature.

[0003] The specification of Chinese invention patent CN107103660B discloses a driving recorder with a sunshade and sun protection structure, which is equipped with a sun protection plate and can be flexibly installed and fixed. In addition, the specification of Chinese invention patent CN108399663A discloses a sun protection and heat dissipation device for a driving recorder, which intelligently prevents the recorder from being directly exposed to sunlight and plays a role in sun protection and heat dissipation.

[0004] Existing sun protection and heat dissipation equipment for driving recorders generally uses an open sun visor to provide sun protection when working. However, when the car is parked in summer, the air conditioner in the car stops and the temperature in the car rises rapidly. At this time, even if the fan of the driving recorder is activated for heat dissipation, the exchange flow of the airflow is the high-temperature airflow of the closed car body, and the heat dissipation effect is limited. Summary of the invention

[0005] In view of the above-mentioned prior art, the technical problem to be solved by the present invention is how to provide effective sun protection for the driving recorder in the closed vehicle body when the vehicle is parked, so as to avoid shortening the service life of the driving recorder.

[0006] In order to solve the above problems, the present invention provides a sunscreen and heat dissipation device for a driving recorder, comprising a sunshade frame installed on a vehicle body and a recorder body installed in the sunshade frame, wherein an opening is provided on the front of the sunshade frame, a notch is provided on the back of the sunshade frame, a movable plate is rotatably installed on the top wall of the notch through an axis, a plurality of extrusion springs are installed on the back of the recorder body, a placement box is installed on the top of the sunshade frame, a main electric rotating rod and a sub-electric rotating rod are rotatably connected to the inner wall of the placement box, and gears meshing with each other are respectively installed on one end of the main electric rotating rod and the sub-electric rotating rod, and the main electric rotating rod and the sub-electric rotating rod are respectively meshed with each other. A pulling rope is wrapped around the surface of the rotating rod, and a plurality of guide pulleys are installed on the inner wall of the sunshade frame, the surface of the pulling rope is wrapped around the surfaces of the plurality of guide pulleys and the tail end of the pulling rope is connected to the bottom end of the surface of the movable plate, a heat insulation film is wrapped around the surface of the auxiliary electric rotating rod, a counterweight slide bar is connected to the bottom of the heat insulation film, four constraint slide grooves connected end to end are opened on the front of the sunshade frame, the inner walls of the two vertically arranged constraint slide grooves are slidably connected to the counterweight slide bar, an electromagnetic strip is installed on the inner wall of the constraint slide groove, and four soft magnetic tapes that attract each other with the electromagnetic strips are connected to the surface of the heat insulation film on one side facing the constraint slide groove.

[0008] As a further improvement of the present application, the projection of the installation position of the extrusion spring in the horizontal direction is located inside the movable plate, and the extrusion spring is in a compressed state when the movable plate is in a vertically placed state.

[0009] As a further improvement of the present application, the sunshade frame and the movable panel are both made of heat-insulating plates, the heat-insulating film is made of polycarbonate material, and the gravity of the counterweight sliding rod is greater than the own gravity of the heat-insulating film.

[0010] As a further improvement of the present application, the cross-sectional length of the thermal insulation film is greater than the cross-sectional length of the opening on the front of the sunshade frame, and the length of the two vertically arranged constraint grooves is greater than the cross-sectional width of the opening on the front of the sunshade frame.

[0011] As a further improvement of the present application, the surface of the lowest guide pulley of the sunshade frame is in contact with the surface of the movable plate in the vertical state, a temperature sensor is installed on the surface of the sunshade frame, and the temperature sensor is connected to the signals of the main electric rotating rod and the auxiliary electric rotating rod, and the winding directions of the surfaces of the main electric rotating rod and the auxiliary electric rotating rod are opposite.

[0012] As a further improvement of the present application, it also includes a sun protection control system, which includes a closing module, a constraint module and a monitoring module. The closing module is connected to the main electric rotating rod and the auxiliary electric rotating rod signals for controlling the opening and closing of the movable panel and the thermal insulation film. The constraint module is connected to the electromagnetic strip signal for closing the thermal insulation film and the opening. The monitoring module is connected to the control center signal of the vehicle body for monitoring whether the vehicle body is in a parking state.

[0013] As a further improvement of the present application, the working steps of the sun protection control system are as follows:

[0014] S1, using the monitoring module to determine whether the vehicle is in a parking state, if so, using the temperature sensor to monitor whether the temperature inside the vehicle exceeds the safety threshold, if so, enter S2;

[0015] S2, start the main electric rotating rod and the auxiliary electric rotating rod, drive the pulling rope to reel in and drive the thermal insulation film to release and descend, drive the movable plate and the thermal insulation film to form a closed thermal insulation structure with the sunshade frame;

[0016] S3, then start the electromagnetic strip, and use the magnetic attraction to press and restrain the area of ​​the thermal insulation film outside the opening;

[0017] S4. After the vehicle body is restarted, the electromagnetic bar is powered off and the main electric rotating rod and the auxiliary electric rotating rod rotate in the opposite direction, so that the movable plate resumes the inclined placement state and the thermal insulation film returns to the position close to the top of the constraint slide slot.

[0020] In summary, the sunshade frame can be flexibly opened and closed by using movable panels and heat-insulating films. The recorder body is insulated to adapt to the damage to the recorder body caused by the rising temperature in the car body when the cooling fan in the car body has insufficient heat dissipation capacity when the car is parked. The use of electromagnetic strips can further enhance the effectiveness of the closure. In addition, the swing unit can effectively protect the recorder body in the event of a collision and reduce collision damage. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0034] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0035] The first implementation method:

[0036] Figure 1-Figure 3A sunscreen and heat dissipation device for a driving recorder is shown, comprising a sunshade frame 1 installed on a vehicle body and a recorder body 001 installed in the sunshade frame 1, wherein an opening is provided on the front of the sunshade frame 1, a notch is provided on the back of the sunshade frame 1, a movable plate 2 is rotatably installed on the top wall of the notch through an axis, a plurality of extrusion springs 3 are installed on the back of the recorder body 001, a placement box 8 is installed on the top of the sunshade frame 1, a main electric rotating rod 6 and a sub-electric rotating rod 7 are rotatably connected to the inner wall of the placement box 8, and one end of the main electric rotating rod 6 and the sub-electric rotating rod 7 They are respectively installed with gears meshing with each other, a pulling rope 4 is wound around the surface of the main electric rotating rod 6, and a plurality of guide pulleys are installed on the inner wall of the sunshade frame 1, the surface of the pulling rope 4 is wound around the surfaces of the plurality of guide pulleys and the tail end of the pulling rope 4 is connected to the bottom end of the surface of the movable plate 2, a heat insulation film 5 is wound around the surface of the auxiliary electric rotating rod 7, and a counterweight slide bar 51 is connected to the bottom of the heat insulation film 5, and four end-to-end constraint slide grooves 101 are opened on the front of the sunshade frame 1, and the inner walls of the two vertically arranged constraint slide grooves 101 are slidably connected to the counterweight slide bar 51;

[0037] Figure 6 As shown, an electromagnetic strip 102 is installed on the inner wall of the constraining slide groove 101 , and four soft magnetic tapes 52 that attract the electromagnetic strip 102 are connected to the surface of the thermal insulation film 5 on one side facing the constraining slide groove 101 .

[0038] Specifically, in this embodiment, a transparent frame corresponding to the camera on the back of the recorder body 001 is installed on the back of the sunshade frame 1, so as to achieve the purpose of sunshade and driving recording.

[0039] In this embodiment, Figure 1 The arrows in the Figure 1 Schematic diagram of the internal structure of the circle after enlargement;

[0040] Figure 4 The arrow at the end of the arc segment in the figure indicates the movement trend of the movable plate 2, the arrow in the middle indicates that the pulling rope 4 is lifted and moves upward, and the arrow on the far right indicates the downward movement direction of the thermal insulation film 5;

[0041] Figure 5 The arrow at the end of the middle arc segment indicates the tendency of the movable plate 2 to move to the left, and the arrow on the right indicates the tendency of the thermal insulation film 5 to move upward.

[0042] When providing sunshade and heat dissipation service for the recorder body 001, the movable plate 2 is in a tilted state in a normal state (that is, the vehicle body is in use, the air conditioner in the vehicle body is enabled, or the temperature in the vehicle body is always below the safety threshold), and the heat insulation film 5 is located near the top of the constraint slide groove 101, so that there is a large exposed space on the front and back of the sunshade frame 1, which can facilitate the viewing of the display screen of the recorder body 001 and will not affect the heat dissipation of the back of the recorder body 001. The movable plate 2 in the inclined state can also provide sunshade service for the back of the recorder body 001 (such as Figure 5 as shown).

[0043] In summer, when the vehicle is parked, the temperature inside the vehicle will gradually rise and gradually exceed the safety threshold. When the temperature exceeds the safety threshold, the main electric rotating rod 6 and the auxiliary electric rotating rod 7 rotate to drive the pulling rope 4 to reel in and drive the heat insulation film 5 to release, so that the pulling rope 4 gradually approaches the direction of the recorder body 001 until it is in a vertical placement state to fill the gap (such as Figure 4 As shown), at the same time, the heat-insulating film 5 covers the opening on the front side of the sunshade frame 1, initially forming a closed structure for the sunshade frame 1, preventing the heat outside the sunshade frame 1 in the vehicle body from transferring and diffusing to the inside of the sunshade frame 1, which can achieve a better sunshade and heat dissipation effect (because the vehicle body is in a parked state at this time, even if the recorder body 001 needs to be used, the heat-insulating film 5 is made of polycarbonate material, and the transparent heat-insulating film 5 will not interfere with the driving recording operation of the recorder body 001 to the rear of the vehicle body).

[0044] In this embodiment, the insulation film 5 slides down under the gravity of the counterweight slide bar 51 until the opening is covered. Since the insulation film 5 is relatively thin and light, the sealing effect on the opening is limited. At this time, the electromagnetic strip 102 is started to drive the soft magnetic tape 52 to be attracted closer, so that the insulation film 5 located on the surface of the constraint slide groove 101 is partially pressed against the surface of the constraint slide groove 101, thereby achieving a better closing and restraining effect on the opening.

[0045] The projection of the installation position of the compression spring 3 in the horizontal direction is located inside the movable plate 2 , and the compression spring 3 is in a compressed state when the movable plate 2 is in a vertically placed state.

[0046] Specifically, the extrusion spring 3 is in a compressed state when the movable panel 2 is used for closed service, and is used to provide an initial thrust when the pulling rope 4 is subsequently released, so that the movable panel 2 can be smoothly in a tilted state.

[0047] The sunshade frame 1 and the movable plate 2 are both made of heat-insulating plates, and the gravity of the counterweight sliding rod 51 is greater than the self-gravity of the heat-insulating film 5 .

[0048] Specifically, the heat-insulating material can enable the sunshade frame 1 in a closed state to provide heat insulation for the recorder body 001 , thereby preventing the rising temperature inside the vehicle from affecting the recorder body 001 .

[0049] The cross-sectional length of the heat-insulating film 5 is greater than the cross-sectional length of the opening on the front of the sunshade frame 1 , and the length of the two vertically arranged constraint slots 101 is greater than the cross-sectional width of the opening on the front of the sunshade frame 1 .

[0050] Specifically, due to the difference in cross-sectional length between the thermal insulation film 5 and the opening and the difference in cross-sectional dimensions between the two vertically arranged constraint slots 101 and the opening, when the thermal insulation film 5 covers the opening, it can achieve full coverage with some margin for the subsequent attraction and pressing treatment of the electromagnetic strip 102.

[0051] The surface of the lowest guide pulley of the sunshade frame 1 is in contact with the surface of the movable plate 2 in the vertical state. A temperature sensor is installed on the surface of the sunshade frame 1, and the temperature sensor is connected to the main electric rotating rod 6 and the auxiliary electric rotating rod 7 by signal. The winding directions of the surfaces of the main electric rotating rod 6 and the auxiliary electric rotating rod 7 are opposite.

[0052] Specifically, the movable plate 2 is subjected to the abutment treatment by the surface of the lowermost guide pulley, so that the movable plate 2 is restricted by the surface of the guide pulley during the resetting process, so that the movable plate 2 cannot continue to deflect after reaching the vertical state during resetting.

[0053] Since the main electric rotating rod 6 and the auxiliary electric rotating rod 7 are rolled up in opposite directions when turning, the movable plate 2 can be reset and closed, the thermal insulation film 5 can be moved down to cover, and the movable plate 2 can be moved and tilted, and the thermal insulation film 5 can be moved up to expose.

[0054] It also includes a sun protection control system, which includes a closing module, a restraint module and a monitoring module. The closing module is connected to the main electric rotating rod 6 and the auxiliary electric rotating rod 7 by signal, and is used to control the opening and closing of the movable panel 2 and the thermal insulation film 5. The restraint module is connected to the electromagnetic strip 102 by signal, and is used to close the thermal insulation film 5 and the opening. The monitoring module is connected to the control center of the vehicle body by signal, and is used to monitor whether the vehicle body is in a parking state.

[0055] The working steps of the sun protection control system are as follows:

[0056] S1, using the monitoring module to determine whether the vehicle is in a parking state, if so, using the temperature sensor to monitor whether the temperature inside the vehicle exceeds the safety threshold, if so, enter S2;

[0057] S2, start the main electric rotating rod 6 and the auxiliary electric rotating rod 7, drive the pulling rope 4 to reel up and drive the heat insulation film 5 to release and descend, drive the movable plate 2 and the heat insulation film 5 to form a closed heat insulation structure with the sunshade frame 1;

[0058] S3, then start the electromagnetic strip 102, and use the magnetic attraction to press and constrain the area of ​​the thermal insulation film 5 outside the opening;

[0059] S4, after the vehicle body is restarted, the electromagnetic strip 102 is powered off and the main electric rotating rod 6 and the auxiliary electric rotating rod 7 rotate in the opposite direction, so that the movable plate 2 resumes the inclined placement state and the heat insulation film 5 returns to the position close to the top of the constraint slide groove 101.

[0060] Specifically, the monitoring module is used to determine whether the vehicle body is in the start-up state, because if the vehicle body is in the start-up state, the air conditioner in the vehicle body is generally in the start-up state (cooling is required when the temperature is high, and even in cold weather, the air conditioner is heated, and it will not reach the high temperature in summer, and the temperature value will not exceed the safety threshold). At this time, the sunshade frame 1 in the vehicle body needs to remain exposed. If the air conditioner in the vehicle body is not turned on (that is, the temperature is at normal room temperature, and there is no need to use the air conditioner for cooling or heating, the temperature change trend in the vehicle body tends to be stable, and the temperature value will not exceed the safety threshold), the sunshade frame 1 in the vehicle body can remain exposed, and the sunshade frame 1 and the tilted movable plate 2 can provide sunshade services;

[0061] If the vehicle body is not in the starting state and the temperature inside the vehicle body is rising and gradually exceeds the safety threshold, it is necessary to start the sealing module and the constraint module to implement the corresponding sealing processing to prevent heat diffusion from affecting the recorder body 001.

[0062] The second implementation method:

[0063] Figure 7-Figure 8 It is shown that the interior of the sunshade frame 1 is installed with a swing unit 9 located behind the placement box 8, the swing unit 9 includes a mounting shaft seat 91, and the two ends of the mounting shaft seat 91 are fixed to the top of the sunshade frame 1 by bolts, and the interior of the mounting shaft seat 91 is rotatably installed with a shaft rod 92, and the surface of the shaft rod 92 is connected to the top of the recorder body 001, and a magnetic plug-in 94 is slidably connected to the top of the sunshade frame 1, and a cylinder 93 is installed on the top of the sunshade frame 1, and the top of the cylinder 93 is connected to an electromagnetic ring 95 that attracts the magnetic plug-in 94.

[0064] Fig.10 It is shown that a plug-in notch is provided on the surface of the shaft 92, and the cross section of the plug-in notch is engaged with the surface of the magnetic dynamic plug-in 94, and in the initial state, the magnetic dynamic plug-in 94 is flush with the bottom end of the plug-in notch.

[0065] Different from the first embodiment, this embodiment is mainly aimed at the impact protection of the recorder body 001. In this embodiment, a pressure sensor connected to the signal of the electromagnetic ring 95 is installed on the front of the movable plate 2.

[0066] In this embodiment, Fig. 9 The arrow in the figure means that the magnetic plug-in 94 moves upward and leaves the mounting shaft seat 91. Fig.11 The three horizontal arrows indicate the direction of the impact force, and the arc-shaped arrow indicates the movement direction of the recorder body 001.

[0067] In this embodiment, the recorder body 001 is installed on the surface of the shaft 92, and there is a certain gap between the top of the recorder body 001 and the surface of the mounting shaft seat 91 (so that the recorder body 001 can swing under the action of the shaft 92 later), and the recorder body 001 is bolted to the sunshade frame 1 through bolts at both ends of the mounting shaft seat 91, and then the shaft 92 is constrained to rotate by the naturally falling magnetic plug-in 94, so that it drives the recorder body 001 to be fixed inside the sunshade frame 1.

[0068] When the vehicle encounters an impact from the front of the vehicle glass during driving (in this state, the thermal insulation film 5 in the vehicle is in the storage state, because the air conditioner in the vehicle is turned on or the temperature in the vehicle is lower than the safety threshold, the thermal insulation film 5 does not need to be lowered for insulation), the movable plate 2 first cooperates with the extrusion spring 3 for buffering, and when the movable plate 2 is hit, the electromagnetic ring 95 starts to drive the magnetic plug-in 94 to move upward (such as Fig. 9 As shown), the shaft 92 loses its restraining effect, and then the recorder body 001 is in an active state in the sunshade frame 1. As the impact is transmitted, the recorder body 001 is in non-rigid contact with the impact, reducing the impact damage (such as Fig.11 as shown).

[0069] In summary, the present application utilizes the movable plate 2 and the heat-insulating film 5 to flexibly realize the opening and closing processing of the sunshade frame 1, and performs heat-insulating treatment on the recorder body 001 to adapt to the damage to the recorder body 001 caused by the continuously rising temperature in the vehicle body when the heat dissipation capacity of the heat dissipation fan in the vehicle body is insufficient when the vehicle is parked, and cooperates with the use of the electromagnetic strip 102 to further enhance the effectiveness of the closure. In addition, in conjunction with the swing unit 9, it can effectively protect the recorder body 001 in the event of a collision and reduce the impact damage.

[0070] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
