Description

Technical Field

[0001] The present invention relates to the technical field of automobiles, and particularly to an intelligent central control navigation auxiliary pointing device for intelligent vehicles. Background Art

[0002] The intelligent central control navigation of intelligent vehicles generally refers to an in-vehicle navigator with functions such as map navigation, real-time traffic information display, and intelligent auxiliary pointing. It usually has a display screen and audio function, and can provide functions such as maps, steering prompts, real-time traffic information, etc. to help users accurately reach their destinations. The navigator usually has a visual interface where users can input the starting and ending points. It determines the user's exact location through global positioning system technology and guides the user to the destination through map display and voice prompts. The navigator is widespread in the use of automobiles.

[0003] However, after specific use and comparison with existing mature technologies, there are still the following deficiencies in the use of the navigator:

[0004] 1. During the driving process of the vehicle, the items inside the vehicle may move or fall due to sudden braking or impact, and these unexpected events may cause impact on the surface of the navigator, resulting in damage to the navigator or even inability to work properly. Once the navigator is damaged, the vehicle owner needs to spend economic costs for repair or replacement, causing economic losses to the vehicle owner and affecting daily safe travel and navigation experience.

[0005] 2. In the daily use of the vehicle, a layer of fine dust is easily attached to the surface of the navigator. These dusts not only reduce the brightness of the navigator's surface but may also blur the content on the display screen. If the driver cannot clearly see the map and route displayed on the navigator, it will seriously hinder their normal use experience and driving safety.

[0006] 3. The existing navigator is provided with heat dissipation openings for cooling and ventilating the navigator itself. When a large amount of dust and impurities are in a floating state, the dust and impurities are likely to enter the vehicle's heat dissipation openings and cause blockage. Such blockage may seriously affect the heat dissipation and ventilation work inside the vehicle's heat dissipation openings. If the heat dissipation openings are blocked, the life of the navigator may be seriously affected.

[0007] Therefore, the present invention proposes an intelligent central control navigation auxiliary pointing device for intelligent vehicles to make up for and improve the deficiencies of the existing technology. Summary of the Invention

[0008] In view of the defects existing in the prior art, the present invention provides an intelligent central control navigation auxiliary pointing device for a smart car, which can effectively solve the technical problems that the objects in the car may move or fall and damage the navigator due to sudden braking or collision during driving, the driver needs to clean and dust the surface of the navigator regularly, otherwise it may cause unclear use and even affect the driver's driving safety, and the large amount of dust and impurity particles in the air may block the heat dissipation ports and affect the internal heat dissipation and ventilation work.

[0009] To achieve the above objectives, the present invention is implemented through the following technical solutions:

[0012] The automatic dust removal mechanism is used to clean and remove dust attached to the front side of the navigator body;

[0013] The dust shielding mechanism is used to shield the heat dissipation port while shielding the front side of the navigator body to remove dust, so as to avoid clogging the heat dissipation port when there is a lot of floating dust in the air.

[0014] Preferably, torsion springs are connected between the two ends of the first rotating shaft and the inner wall of the fixed housing. The transparent curved plate is made of a rollable PVC transparent plastic plate. The bottom surface of the transparent curved plate is attached to the circumferential surface of the roller, and the frictional force when the transparent curved plate is attached to the roller can cause the roller to rotate.

[0015] Preferably, the end of the second connecting plate away from the synchronous belt is fixedly connected to the bottom of the end of the transparent curved plate located on the front side of the navigator body.

[0016] Preferably, the automatic dust removal mechanism includes an incomplete gear fixedly connected to one side of the roller. A rack is meshed with the outer wall of the incomplete gear. A second spring is fixedly connected to the outer wall of the rack away from the incomplete gear. A piston plate is fixedly connected to the side of the rack away from the incomplete gear. The outer wall of the piston plate is slidably connected to a piston chamber fixedly installed at the upper end of the navigator body. A guide air cylinder is communicated with the side of the piston chamber close to the incomplete gear. The guide air cylinder is communicated with a dust suction cylinder at the side away from the piston chamber. A rubber squeegee is fixedly connected to the bottom of the transparent curved plate.

[0017] Preferably, the second spring is fixedly connected between the end away from the rack and the piston chamber. The dust suction cylinder is fixedly connected to the fixed shaft. The dust suction cylinder is located directly above the rubber squeegee. A one-way valve is arranged inside the guide air cylinder.

[0018] Preferably, the dust shielding mechanism includes a T-shaped sliding groove opened on the outside of the navigator body. A T-shaped slider is slidably connected to the inner wall of the T-shaped sliding groove. A shielding plate is fixedly connected to the side of the T-shaped slider located outside the navigator body. A first magnetic attraction block is fixedly installed on the outer wall of the bottom of the shielding plate close to the T-shaped slider. A second magnetic attraction block is fixedly installed on the outer wall of the synchronous belt.

[0019] Preferably, the first magnetic attraction block and the second magnetic attraction block are magnets with opposite magnetic polarities. The first magnetic attraction block is directly below the second magnetic attraction block.

[0020] Adopting the technical solution provided by the present invention, compared with the known public technology, the following beneficial effects are achieved:

[0021] The present invention uses the second connecting plate to drive the transparent curved plate to start moving downward along the front side of the navigator main body, covering the front side of the navigator main body. Since the objects inside the vehicle may move or fall due to sudden braking or impact during the driving of the vehicle, it may impact the navigator main body and damage it, causing economic losses to the user. Therefore, when the vehicle brakes suddenly or is impacted, the small ball inside the fixed cylinder drives the first connecting plate to contact or move away from the switch button of the motor, thereby controlling the transparent curved plate to quickly descend for shielding, so as to protect the front side of the navigator main body, reduce the probability of the navigator main body being damaged by the objects inside the vehicle, and improve the safety of the navigator main body during the driving of the vehicle.

[0022] The present invention repeatedly generates suction inside the piston chamber to drive the bottom of the dust suction cylinder to suck the dust scraped off the upper end of the rubber squeegee. Since the surface of the navigator main body placed inside the vehicle will be attached with dust during the daily use of the vehicle, this will interfere with the normal use of the driver. The driver needs to regularly clean and remove the dust on the surface of the navigator main body. Otherwise, it may lead to unclear use and even affect the driving safety of the driver. Therefore, while the device shields and protects the front side of the navigator main body, it scrapes and sucks the dust on the front side of the navigator main body, which can assist the driver to automatically clean the surface of the navigator main body, save manpower, and keep the surface of the navigator main body clean, thereby improving the use effect of the driver on the navigator main body.

[0023] When the second magnetic attraction block moves to the position of the first magnetic attraction block, it will drive the first magnetic attraction block to move downward following the movement of the second magnetic attraction block and move to the front side of the heat dissipation port. Since when the piston plate sweeps the front side of the navigator main body, some dust on the surface of the navigator main body will be in a floating state. At this time, there are many dust impurity particles in the air, which are very likely to block the heat dissipation port and affect the heat dissipation and ventilation work inside it. Therefore, the present invention uses the synchronous action of the second magnetic attraction block and the first magnetic attraction block during the movement process, so that the surface of the heat dissipation port will not have too much dust and impurities entering during the floating process, thereby reducing the cleaning cycle of the heat dissipation port, and thus maintaining the ventilation and heat dissipation effects of the heat dissipation port during use.

[0024] The present invention uses the transmission of the motor driving the synchronous belt to drive the synchronous movement of the shielding and protection mechanism, the automatic dust removal mechanism, and the dust shielding mechanism, making the transmission of the overall mechanism highly automated and integral. And the transparent curved plate is made of transparent PVC plastic plate, so that the driver's vision will not be blocked during the shielding process. Description of the Drawings

[0042] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Apparently, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0043] The present invention will be further described below with reference to the embodiments.

[0044] Embodiments of the present invention

[0045] An intelligent central control navigation auxiliary pointing device for an intelligent vehicle, refer to Figure 1 And Figure 3 As shown, it includes a navigator main body 1. A screen button 11 is arranged on the front side of the navigator main body 1, and a heat dissipation port 12 is opened on the rear side of the navigator main body 1:

[0046] A shielding and protecting mechanism 2 is arranged at the upper end of the navigator main body 1 for shielding the front side of the navigator main body 1 during emergency braking and impact;

[0047] Refer to Figures 2 to 5As shown in the figure, the shielding protection mechanism 2 includes a fixed housing 21 fixedly installed at the upper end of the navigator main body 1. A first rotating shaft 22 is rotatably connected to the inner wall of the fixed housing 21. A transparent curved plate 23 is wound around the outer wall of the first rotating shaft 22. Two fixed shafts 24 are fixedly connected to the inner wall of the fixed housing 21. A roller 241 is rotatably connected to the outer wall of the fixed shaft 24. Torsion springs are connected between the two ends of the first rotating shaft 22 and the inner wall of the fixed housing 21. The transparent curved plate 23 is made of a rollable PVC transparent plastic plate. The bottom surface of the transparent curved plate 23 is attached to the circumferential surface of the roller 241, and the frictional force when the transparent curved plate 23 is attached to the roller 241 can cause the roller 241 to rotate. A fixed cylinder 25 is fixedly installed on the upper side wall of the navigator main body 1. A motor 26 is fixedly installed at the upper end of the fixed cylinder 25. A controller for controlling the start or stop of the motor is connected to the motor 26. A switch button is provided on the controller. The output shaft end of the motor 26 is drivingly connected to a synchronous belt 27. A second connecting plate 28 is fixedly connected to the outer wall of the synchronous belt 27. One end of the second connecting plate 28 away from the synchronous belt 27 is fixedly connected to the bottom of one end of the transparent curved plate 23 located on the front side of the navigator main body 1. A sliding plate 251 is slidably connected to the inner wall of the fixed cylinder 25. A first spring 252 passing through the fixed cylinder 25 is fixedly connected to the side of the sliding plate 251 away from the navigator main body 1. One end of the first spring 252 away from the sliding plate 251 is fixedly connected to a first connecting plate 253. A movable small ball is provided between the side of the sliding plate 251 close to the navigator main body 1 and the inside of the fixed cylinder 25. When the vehicle brakes suddenly or is impacted, the small ball inside the fixed cylinder 25 will move towards the sliding plate 251 due to inertia. When the vehicle brakes suddenly or stops due to impact, due to the mass of the small ball inside the fixed cylinder 25, the small ball will generate an inertial force to impact the sliding plate 251, and cause the first connecting plate 253 to move away from the switch button on the controller of the motor 26. By using the switch button, the controller is used to start the motor. When one end of the first connecting plate 253 away from the first spring 252 is in contact with the switch button of the motor 26, the switch is in the closed state. When the first connecting plate 253 moves away from the switch button of the motor 26, the motor 26 will be in the starting state;

[0048] Summary 1: Since the objects inside the vehicle may move or fall due to sudden braking or impact during the driving of the vehicle, it may impact the navigator main body 1 and damage the navigator main body 1, causing economic losses to the vehicle. Therefore, this device uses the small ball inside the fixed cylinder 25 to drive the first connecting plate 253 to contact or move away from the switch button of the motor 26 when the vehicle brakes suddenly or is impacted, so as to control the rapid descent of the transparent curved plate 23 for shielding, thereby protecting the front side of the navigator main body 1.

[0049] An automatic dust removal mechanism 3 is provided on the front side of the shielding protection mechanism 2 for cleaning and sucking the dust attached to the front side of the navigator main body 1;

[0050] Reference Figures 6 to 9 As shown, the automatic dust removal mechanism 3 includes an incomplete gear 31 fixedly connected to one side of the roller 241. A rack 32 is meshed with the outer wall of the incomplete gear 31. A second spring 33 is fixedly connected to the outer wall of the rack 32 away from the incomplete gear 31. A piston plate 37 is fixedly connected to the side of the rack 32 away from the incomplete gear 31. The outer wall of the piston plate 37 is slidably connected to a piston chamber 34 fixedly installed at the upper end of the navigator main body 1. The end of the second spring 33 away from the rack 32 is fixedly connected to the piston chamber 34. A gas guide cylinder 35 communicates with the side of the piston chamber 34 close to the incomplete gear 31. A dust suction cylinder 36 communicates with the side of the gas guide cylinder 35 away from the piston chamber 34. The dust suction cylinder 36 is fixedly connected to the fixed shaft 24. A rubber squeegee 38 is fixedly connected to the bottom of the transparent curved plate 23;

[0051] Summary II: Since dust will adhere to the surface of the navigator main body 1 placed inside the car during daily use, which will hinder the normal use of the driver. The driver needs to regularly clean and remove the dust on the surface of the navigator main body 1. Otherwise, it may lead to unclear use and even affect the driving safety of the driver. Therefore, this device uses the function of scraping and sucking dust on the front side of the navigator main body 1 while protecting the front side of the navigator main body 1.

[0052] A dust shielding mechanism 4 is arranged in the middle of the navigator main body 1, which is used to shield the front side of the navigator main body 1 from dust and at the same time shield the heat dissipation port 12 to prevent blockage of the heat dissipation port 12 when there is a lot of floating dust in the air;

[0053] Reference Figure 5 , Figures 9 to 11 As shown, the dust shielding mechanism 4 includes a T-shaped sliding groove 42 opened on the outside of the navigator main body 1. A T-shaped slider 43 is slidably connected to the inner wall of the T-shaped sliding groove 42. A shielding plate 41 is fixedly connected to the side of the T-shaped slider 43 located outside the navigator main body 1. A first magnetic attraction block 44 is fixedly installed on the outer wall of the bottom of the shielding plate 41 close to the T-shaped slider 43. A second magnetic attraction block 45 is fixedly installed on the outer wall of the synchronous belt 27. The first magnetic attraction block 44 and the second magnetic attraction block 45 are magnets with opposite magnetic poles;

[0054] Summary III: Since when the piston plate 37 sweeps the front side of the navigator main body 1, some dust on the surface of the navigator main body 1 will be in a floating state. At this time, there are many dust impurity particles in the air, which is very likely to cause blockage of the heat dissipation port 12 and affect the internal heat dissipation and ventilation work. Therefore, this device uses the synchronous action of the second magnetic attraction block 45 and the first magnetic attraction block 44 during the movement process, so that the surface of the heat dissipation port 12 will not be blocked by too much dust and impurities during floating.

[0055] The complete working principle and steps of the above embodiments are as follows:

[0056] During use:

[0057] Occlusion protection steps:

[0058] As shown by Figures 2 to 5 Since the fixed shell 21 is fixedly installed at the upper end of the navigator main body 1, and a first rotating shaft 22 is rotatably connected to the inner wall of the fixed shell 21. Also, since a transparent curved plate 23 is wound around the outer wall of the first rotating shaft 22, and the transparent curved plate 23 is a PVC transparent plastic plate that can be curled. Since torsion springs are connected between both ends of the first rotating shaft 22 and the inner wall of the fixed shell 21, when the transparent curved plate 23 is forced to move away from the first rotating shaft 22, it will drive the first rotating shaft 22 to rotate relative to the fixed shell 21, so that when the transparent curved plate 23 moves away from the first rotating shaft 22, it will be in a stretched state. And when one end of the transparent curved plate 23 away from the first rotating shaft 22 is not stressed, the transparent curved plate 23 will return to the curled state due to the elastic force of the torsion spring. Since two fixed shafts 24 are fixedly connected to the inner wall of the fixed shell 21, and the bottom surface of the transparent curved plate 23 is attached to the circumferential surface of the roller 241, and the frictional force in the attached state between the transparent curved plate 23 and the roller 241 can cause the roller 241 to rotate. Also, since the outer wall of the roller 241 is slidably connected to the bottom of the transparent curved plate 23, when the transparent curved plate 23 is forced to move away from the first rotating shaft 22, it will slide along the outer wall of the roller 241 and drive the roller 241 to rotate. Since a sliding plate 251 is slidably connected to the inner wall of the fixed cylinder 25 fixedly installed at the upper end of the navigator main body 1, a first spring 252 penetrating the fixed cylinder 25 is fixedly connected to the side of the sliding plate 251 away from the navigator main body 1. Also, since a first connecting plate 253 is fixedly connected to the end of the first spring 252 away from the sliding plate 251, and movable balls are provided between the side of the sliding plate 251 close to the navigator main body 1 and the inside of the fixed cylinder 25, when the vehicle brakes suddenly or is impacted, the balls inside the fixed cylinder 25 will be driven to move towards the sliding plate 251 due to inertia;

[0059] Since the upper end of the fixed cylinder 25 is fixedly installed with a motor 26, and one end of the first connecting plate 253 away from the first spring 252 is in contact with the switch button on the controller of the motor 26, and the switch is in a closed state in the contact state. When the first connecting plate 253 moves away from the switch button of the motor 26, the motor 26 will be in a starting state. Also, since the output shaft end of the motor 26 is drivingly connected with a synchronous belt 27, and the outer wall of the synchronous belt 27 is fixedly connected with a second connecting plate 28. Therefore, when the vehicle brakes suddenly or stops due to being hit, due to the mass of the small ball inside the fixed cylinder 25, the small ball will generate an inertial force to impact the sliding plate 251, and cause the first connecting plate 253 to move away from the switch button of the motor 26, making the motor 26 start and drive the synchronous belt 27 to rotate, thereby driving the second connecting plate 28 to move up and down. Since one end of the second connecting plate 28 away from the synchronous belt 27 is fixedly connected to the bottom of one end of the transparent curved plate 23 located on the front side of the navigator main body 1, the second connecting plate 28 will drive the transparent curved plate 23 to start moving downward along the front side of the navigator main body 1 to shield the front side of the navigator main body 1. When the second connecting plate 28 drives the transparent curved plate 23 to move to the bottom of the navigator main body 1, the shielding ends at this time, and the motor 26 will reverse, driving the part of the transparent curved plate 23 located on the front side of the navigator main body 1 to move upward. At the same time, the transparent curved plate 23 returns to the curled state due to the elastic force of the torsion spring. At this time, the transparent curved plate 23 will move in the reverse direction to the initial position. When the sudden braking of the vehicle ends, the small ball inside the fixed cylinder 25 will gradually stop. At this time, due to the elastic force of the first spring 252, the first connecting plate 253 will be reset and the switch of the motor 26 will be turned off. Since the objects inside the vehicle may move or fall due to sudden braking or being hit during the driving of the vehicle, it may impact the navigator main body 1 and damage the navigator main body 1, bringing economic losses to the vehicle. Therefore, this device uses the small ball inside the fixed cylinder 25 to drive the first connecting plate 253 to contact or move away from the switch button of the motor 26 when the vehicle brakes suddenly or is hit, thereby controlling the transparent curved plate 23 to quickly descend for shielding, so as to protect the front side of the navigator main body 1, reduce the probability of the navigator main body 1 being damaged by the impact of the objects inside the vehicle, and increase the safety of the navigator main body 1 during the driving of the vehicle;

[0060] Automatic dust suction steps:

[0061] By Figures 6 to 9As shown in the figure, since the automatic dust removal mechanism 3 includes an incomplete gear 31 fixedly connected to one side of the drum 241, and a rack 32 is meshed with the outer wall of the incomplete gear 31, when the incomplete gear 31 rotates following the rotation of the drum 241, it will drive the rack 32 to move left and right. Since a second spring 33 is fixedly connected to the outer wall of the side of the rack 32 away from the incomplete gear 31, and a piston plate 37 is fixedly connected to the side of the rack 32 away from the incomplete gear 31. Also, since the outer wall of the piston plate 37 is slidably connected to a piston chamber 34 fixedly installed at the upper end of the navigator main body 1, and the piston chamber 34 is fixedly installed at the upper end of the navigator main body 1, when the rack 32 moves left and right, it will drive the piston plate 37 to slide along the inner wall of the piston chamber 34, thereby driving the second spring 33 to elastically deform between the rack 32 and the piston chamber 34, so that the rack 32 can return to the initial position where it meshes with the incomplete gear 31. Since an air guide cylinder 35 is connected to the side of the piston chamber 34 close to the incomplete gear 31, and a dust suction cylinder 36 is connected to the side of the air guide cylinder 35 away from the piston chamber 34. Also, since the dust suction cylinder 36 is fixedly connected to the fixed shaft 24, and a rubber squeegee 38 is fixedly connected to the bottom of the transparent curved plate 23, the rubber squeegee 38 can move up and down following the transparent curved plate 23 and scrape the dust on the front side of the navigator main body 1. Since the dust suction cylinder 36 is located directly above the rubber squeegee 38, and a one-way valve is provided inside the air guide cylinder 35, only suction can be generated above the rubber squeegee 38 inside the piston chamber 34, and the inside of the piston chamber 34 will repeatedly generate suction inside the dust suction cylinder 36 due to the movement of the rack 32, driving the bottom of the dust suction cylinder 36 to suck the dust scraped by the upper end of the rubber squeegee 38. Since dust will adhere to the surface of the navigator main body 1 placed inside the vehicle during daily use, which will interfere with the normal use of the driver. The driver needs to regularly clean and remove the dust on the surface of the navigator main body 1, otherwise it may cause unclear use and even affect the driving safety of the driver. Therefore, this device can assist the driver to automatically clean the surface of the navigator main body 1 by scraping and sucking the dust on the front side of the navigator main body 1 while shielding and protecting the front side of the navigator main body 1, saving manpower, keeping the surface of the navigator main body 1 clean, and improving the use effect of the driver on the navigator main body 1;

[0062] Dust prevention and anti-blocking steps:

[0063] From Figures 9 to 11As shown, since the T-shaped chute 42 is provided on the outside of the navigator main body 1, and the inner wall of the T-shaped chute 42 is slidably connected to the T-shaped slider 43, and since a baffle 41 is fixedly connected to one side of the T-shaped slider 43 located outside the navigator main body 1, the baffle 41 can slide relative to the outside of the navigator main body 1. Since a first magnetic attraction block 44 is fixedly installed on the outer wall of the bottom of the baffle 41 near one side of the T-shaped slider 43, and a second magnetic attraction block 45 is fixedly installed on the outer wall of the synchronous belt 27, and since the first magnetic attraction block 44 and the second magnetic attraction block 45 are magnets with opposite magnetic polarities, and the first magnetic attraction block 44 is directly below the second magnetic attraction block 45, the first magnetic attraction block 44 will remain stationary due to the magnetic force generated between it and the second magnetic attraction block 45. And when the synchronous belt 27 operates, it will drive the second magnetic attraction block 45 to move up and down following the transmission of the synchronous belt 27. When the second magnetic attraction block 45 moves to the position of the first magnetic attraction block 44, it will drive the first magnetic attraction block 44 to move downward following the movement of the second magnetic attraction block 45 and move to the front side of the heat dissipation opening 12. Since when the rubber squeegee 38 sweeps the front side of the navigator main body 1, some dust on the surface of the navigator main body 1 will be in a floating state. At this time, there are many dust impurity particles in the air, which are very likely to block the heat dissipation opening 12 and affect the heat dissipation and ventilation work inside it. Therefore, the device uses the synchronous action of the second magnetic attraction block 45 and the first magnetic attraction block 44 during the movement process, so that the surface of the heat dissipation opening 12 will not have too much dust and impurities enter during floating, thereby reducing the cleaning cycle of the heat dissipation opening 12, and thus maintaining the ventilation and heat dissipation effects of the heat dissipation opening 12 during use.
