Description

Technical Field

[0001] The invention relates to the technical field of automobiles, in particular to an auxiliary driving side opening device for an automobile sliding door. Background Art

[0002] Side sliding doors are mainly used in various types of cars, commonly seen in multi-purpose vehicles, vans and some commercial vehicles. Structurally, side sliding doors use a track system to open and close the door by sliding sideways. Compared with traditional hinged doors, it has some unique advantages. In terms of space utilization, the side sliding door does not need to swing outward when opened, which is very practical when the parking space is relatively narrow. It can avoid colliding with the vehicle or obstacles next to it due to the opening of the door. For the interior space layout, the side sliding door can make the door opening larger, making it easier for passengers to enter and exit the vehicle, especially for rear passengers to get on and off the vehicle. For models with multiple passengers, it can effectively improve the convenience of riding. Moreover, this opening method of the side sliding door brings a unique visual effect to the appearance of the vehicle and increases the overall recognition of the vehicle.

[0003] However, in the existing automobile side sliding door equipment, since the car may be left unused for a long time, the air quality is seriously deteriorated, and the long-term closure makes it impossible for the air to circulate in the car. Harmful chemicals emitted from the interior, such as formaldehyde and benzene, will continue to accumulate. These substances not only have a pungent smell, but also have great harm to human health, and may cause respiratory diseases, allergic reactions, and even more serious health problems. Secondly, bacteria and mold are easy to breed. The humidity and temperature in the car may be suitable for the reproduction of microorganisms in a closed environment. Seats, carpets and other parts are prone to mold, and bacteria will also multiply in corners such as air-conditioning systems and vents. Once the vehicle is used again, these bacteria and mold will spread to the entire interior space with the air flow, affecting the health of the people in the car. Moreover, the odor is difficult to dissipate. The residual food odor, smoke or other odors in the car will mix together without ventilation to form an unpleasant smell, which will greatly reduce the comfort of riding.

[0004] Therefore, an auxiliary driving side opening device for a sliding door of an automobile is proposed. Summary of the invention

[0015] Compared with the prior art, the present invention has the following beneficial effects: The present invention improves the air quality inside the car by arranging an air storage mechanism, an air intake mechanism and a fragrance mechanism inside the side sliding door. When the side sliding door is opened, the automatic inflation and air intake process starts, and fresh air enters the car. The diaphragm valve in the air storage mechanism can control the inlet and outlet of gas to ensure the reasonable gas exchange. The baffle and turbine structure of the air intake mechanism effectively control the air intake amount and the air intake mode. The activated carbon net in the fragrance mechanism filters impurities and harmful gases, and the fragrance component adds fragrance. This series of designs effectively avoids the problem of air quality degradation caused by long-term storage of the car, reduces the growth of harmful chemicals, bacteria and mold, and provides a healthier air environment for people in the car. The present invention improves the air exchange efficiency through a unique mechanical transmission structure. The connection between the top plate, the nut sleeve and the threaded rod in the air storage mechanism, and the cooperation between the transfer rod, the baffle and the turbine in the air intake mechanism form a set of efficient transmission system. When the side sliding door is opened, the air pump is started, and the change in gas pressure drives the top plate to move, and then the threaded rod is rotated through the ball nut pair, and then the transfer rod is driven to rotate, and finally the baffle is expanded to intake air. This transmission method makes the intake process rapid and stable, and can achieve a large amount of air exchange in a short time, ensuring that the air in the car is quickly updated, and improving the exchange efficiency between the air in the car and the outside air. The effect is particularly significant when the car is opened again after being unused for a long time. The present invention achieves convenient maintenance and replacement through a clever structural design of the fragrance component. The fragrance component is arranged inside the wind wheel, and fragrance can be blown out when the wind wheel shaft rotates. The fragrance component includes a fragrance rod, an elastic rod and other structures, which are connected by tenons, and the upper convex ring and the lower convex ring on the straight rod cooperate, and the fragrance rod can be unlocked when it is pushed. In addition, a slide groove matching the fragrance component is provided on the side of the filter bin, and a handle for pulling it out. This design makes the operation simple and convenient when the fragrance component needs to be replaced. The user can easily take out the fragrance component for replacement or maintenance without complicated tools and operations, thereby reducing maintenance costs and difficulty and improving user experience.

[0016] The present invention arranges an auxiliary door opening mechanism in the air storage bin and utilizes the gas pressure difference to realize easy pulling out of the side sliding door in the initial stage. When the door opening action is triggered, the gas in the air storage bin flows into the air cavity through the air pipe one-way valve. The increased pressure in the air cavity forms a pressure difference with the normal pressure in the vehicle body, pushing the door to move outward. This method effectively overcomes the large resistance during the initial opening of the traditional side sliding door, reduces manpower consumption, and is more convenient to operate with one hand. At the same time, it ensures that the door opening action is smooth and stable, avoids impact and jamming, and greatly improves the comfort of users in opening the door. It is especially convenient for the elderly, children and other people with less strength or those carrying items. BRIEF DESCRIPTION OF THE DRAWINGS

Three baffles 42 are rotatably connected inside the air intake bin 41, and turbines 43 are fixedly connected at both ends of the baffles 42. Three worm gears 46 matching the turbines 43 are fixedly connected to the rotating rod 45 so that the turbines 43 are driven to rotate when the rotating rod 45 rotates. The two ends of the turbine 43 are also fixedly connected to rotating shafts 44 so that the baffles 42 are expanded to intake air when the rotating rod 45 rotates. A fragrance mechanism 5 for filtering air is also provided on the side of the air intake bin 41. A rubber pad for increasing the air tightness of the equipment is provided at the rotating connection between the air storage mechanism 3 and the rotating rod 45, and the elastic mechanism 34 includes a spring, a spiral telescopic tube and a gas strut, so that the top plate 33 can automatically reset after being lifted up, and the ends of the three baffles 42 are fixedly connected with rubber sheets to prevent air intake, so as to ensure the air tightness inside the vehicle body 1 when the baffles 42 are closed, and an infrared sensing device is provided on the side of the side sliding door 2, and the infrared sensing device is electrically connected to the air pump, so that the air pump can be started to inflate when the side sliding door 2 is opened.

[0021] During operation, when the side sliding door 2 is opened, the infrared sensing device on its side quickly senses this action. The infrared sensing device detects the movement of an object based on the reflection or absorption principle of infrared rays. When the side sliding door 2 moves, it will change the propagation path of the surrounding infrared rays, thereby being detected by the infrared sensing device. After the infrared sensing device detects that the door is opened, it will transmit an electrical signal to the air pump connected to it through a preset circuit connection. The air pump starts to work after receiving the signal. It inhales and compresses the external air through its own mechanical structure and working principle, and then transports the compressed air to the air storage bin 31 through a pipeline or other connection methods. A plurality of air inlets 32 are equidistantly provided on the side of the air storage bin 31. The design of these air inlets 32 is to The air can enter the gas storage bin 31 evenly, ensuring the uniform distribution of the gas pressure in the gas storage bin 31. The gas enters the gas storage bin 31 through these air inlets 32. A diaphragm valve 6 is arranged inside the air inlet 32. The working principle of the diaphragm valve 6 is based on the elastic deformation of the diaphragm. When the gas enters, the gas pressure will deform the diaphragm to open the valve, allowing the gas to enter the gas storage bin 31. When the gas pressure in the gas storage bin 31 reaches a certain level, the diaphragm will gradually recover to a certain level under the combined effect of its own elasticity and the gas pressure in the gas storage bin 31, so that the valve is in a state of slow exhaust. In this way, it can be ensured that the gas pressure in the gas storage bin 31 will not be too high, and the gas can be slowly released when needed. As the gas is continuously filled in, the gas inside the gas storage bin 31 As the pressure gradually increases, the top plate 33 is fixedly connected to the inside of the gas storage bin 31 through a plurality of equidistantly arranged elastic mechanisms 34 (such as springs, spiral telescopic tubes or gas struts, etc.). The function of the elastic mechanism 34 is to provide support and reset force for the top plate 33 when the gas pressure changes. When the gas pressure increases to a certain level, the gas will lift up the top plate 33. Nut sleeves 35 are fixedly connected to both ends of the top plate 33. In the process of the top plate 33 being lifted up, the nut sleeve 35 will move on the threaded rod 36. Since the nut sleeve 35 and the threaded rod 36 are connected by a ball nut pair, the ball nut pair is a high-precision transmission mechanism that converts rotary motion into linear motion. When the nut sleeve 35 moves up and down, the balls will roll between the threads of the nut sleeve 35 and the threaded rod 36, thereby The threaded rod 36 is driven to rotate, and the rotation of the threaded rod 36 drives the rotating rod 45 in the air intake mechanism 4 to rotate. Three baffles 42 are rotatably connected inside the air intake chamber 41 of the air intake mechanism 4. Turbines 43 are fixedly connected at both ends of the baffles 42. Three worms 46 matching the turbines 43 are fixedly connected to the rotating rod 45. When the rotating rod 45 rotates, the turbine 43 is driven to rotate through the meshing transmission of the worm 46 and the turbine 43. The meshing transmission of the worm 46 and the turbine 43 is based on the principle of gear transmission. The worm 46 is equivalent to a screw, and the turbine 43 is equivalent to a gear. When the worm 46 rotates, it drives the turbine 43 to rotate. The two ends of the turbine 43 are also fixedly connected with rotating shafts 44. During the rotation of the turbine 43, the rotating shaft 44 will cause the baffles 42 to unfold.Thus, when the car is not used for a long time, the outside air can enter the air intake chamber 41. The expansion process of the baffle 42 is to rotate the baffle 42 around the connection point between the baffle 42 and the air intake chamber 41 through the rotation of the rotating shaft 44, thereby opening the air intake passage.

[0022] As an embodiment of the present invention, Figure 6 and Figure 7 As shown, the fragrance mechanism 5 includes a filter bin 51 and a clamping strip 53 fixedly connected to the upper and lower ends of the filter bin 51, and a groove matching the clamping strip 53 is provided inside the side sliding door 2, so that the filter bin 51 can be quickly disassembled and replaced, an activated carbon net for filtering is provided inside the filter bin 51, and the filter bin 51 is connected to the air vent on the air intake mechanism 4, and a plurality of equidistantly arranged wind wheels 52 are rotatably connected to the side of the filter bin 51, so that the wind wheel 52 is driven to rotate when air is taken in, and the wind wheel 52 includes a fragrance component 521, and the fragrance component 521 is fixedly connected to the inside of the wind wheel shaft 523, so that the fragrance inside the fragrance component 521 is blown out when the wind wheel shaft 523 rotates, and a handle 522 for pulling out the fragrance component 521 is fixedly connected to one end of the fragrance component 521, and a slide groove 54 matching the fragrance component 521 is provided on the side of the filter bin 51, so as to facilitate the disassembly and replacement of the fragrance component 521.

[0023] During operation, a fragrance mechanism 5 is arranged on the side of the air inlet bin 41. The air entering the air inlet bin 41 will be processed by the fragrance mechanism 5. The fragrance mechanism 5 includes a filter bin 51 and a plurality of wind wheels 52 rotatably connected to the side thereof. An activated carbon net is arranged inside the filter bin 51. The activated carbon net utilizes the adsorption characteristics of activated carbon to filter the air. The activated carbon has a huge specific surface area and can absorb impurities, harmful gases and odors in the air. When the air enters the filter bin 51, the air will flow on the surface of the activated carbon net, and the impurities, harmful gases and odors will be adsorbed by the activated carbon, thereby To achieve air filtering and purification, the wind wheel 52 includes a fragrance component 521, and the fragrance component 521 is fixedly connected to the inside of the wind wheel shaft 523. When air enters, it will drive the wind wheel 52 to rotate. When the wind wheel shaft 523 rotates, the fragrance inside the fragrance component 521 is blown out, so that the air entering the car has a pleasant fragrance and is also filtered and purified. The rotation of the wind wheel 52 is based on the power of air flow. When air enters the air intake compartment 41 and flows through the wind wheel 52, the air flow will generate a torque on the wind wheel 52, causing the wind wheel 52 to rotate around its axis.

[0024] As an embodiment of the present invention, Figure 7 and Figure 8As shown, the fragrance component 521 includes a fragrance rod 5211 arranged on one side of the fragrance component 521, and the interior of the fragrance rod 5211 is movably connected to the elastic rod 5213 through the tenon 5212, and a straight rod 524 is fixedly connected to the interior of one side of the wind wheel shaft 523, and the front end of the straight rod 524 is fixedly connected to an upper convex ring 525 matching the elastic rod 5213, and a lower convex ring 526 is also movably connected to the straight rod 524, and the maximum radius of the lower convex ring 526 is greater than the maximum radius of the upper convex ring 525, so that when the fragrance rod 5211 is pushed, the upper convex ring 525 and the tenon 5212 are unlocked by the lower convex ring 526.

[0025] When working, the front end of the straight rod 524 is fixedly connected to the upper convex ring 525 matching the elastic rod 5213, and the straight rod 524 is also movably connected to the lower convex ring 526, and the maximum radius of the lower convex ring 526 is greater than the maximum radius of the upper convex ring 525. When it is necessary to operate the fragrance component 521, such as replacing the fragrance material, the fragrance rod 5211 is pushed, and the movement of the fragrance rod 5211 will drive the elastic rod 5213 to move together. Since the radius of the lower convex ring 526 is larger, when the fragrance rod 5211 moves to a certain extent, the elastic rod 5213 will contact the lower convex ring 526, and as the fragrance rod 5211 moves to a certain extent, the elastic rod 5213 will contact the lower convex ring 526. 5211 continues to be pushed, and the lower convex ring 526 will apply an outward force to the elastic rod 5213, so that the elastic rod 5213 can overcome the engagement with the upper convex ring 525, thereby unlocking the upper convex ring 525 and the tenon 5212 through the lower convex ring 526, so that the fragrance rod 5211 can be taken out of the fragrance component 521, and then the interior of the fragrance component 521 can be maintained or the fragrance substance can be replaced. After the operation is completed, the fragrance rod 5211 is reinserted, and the elastic rod 5213 will re-engage with the upper convex ring 525 under the action of its own elasticity, so that the fragrance component 521 is re-fixed.

[0026] As an embodiment of the present invention, Figure 1 , Figure 2 and Fig. 9 As shown, an auxiliary door opening mechanism 7 for assisting door opening is provided on the side of the air storage bin 31, and the auxiliary door opening mechanism 7 includes two air cavities 71 opened inside the air storage bin 31, and an air pipe 72 is fixedly connected to the inside of the air cavity 71, and a one-way valve 73 for gas to pass is provided inside the air pipe 72, so that the gas pressure difference drives the initial movement of the door body, and a sealing membrane 74 is fixedly connected to the end of the air pipe 72 to prevent air leakage.

[0027] During operation, when the opening action of the side sliding door is triggered (such as the infrared sensing device detecting that the side sliding door handle is pulled, etc.), at this time, the gas pre-stored in the gas storage bin 31 begins to flow to the air cavity 71 in the auxiliary door opening mechanism 7 through the air pipe 72 under the action of the control system. Due to the one-way valve 73 arranged in the air pipe 72, the gas can only flow in the direction from the gas storage bin 31 to the air cavity 71, which effectively prevents the gas from flowing back and ensures that the air cavity 71 can smoothly establish a high-pressure environment. As the gas continues to flow into the air cavity 71, the air cavity 71 is The pressure inside the air cavity 71 rises rapidly. Since the air cavity 71 is located at a specific position inside the side sliding door (close to the edge of the door or a position associated with the force-bearing structure of the door, so as to effectively apply the thrust), and other areas inside the vehicle body are relatively at normal pressure or low pressure at this time (the space inside the vehicle is connected to the outside atmosphere, the air pressure is relatively stable, and an obvious pressure difference is formed with the air cavity 71), this pressure difference generates a strong thrust on both sides of the side sliding door. This thrust directly acts on the side sliding door, pushing the side sliding door to move outward, thereby realizing the initial pulling-out action.

[0028] Working principle: During operation, when the side sliding door 2 is opened, the infrared sensing device on its side quickly senses this action. The infrared sensing device detects the movement of an object based on the reflection or absorption principle of infrared rays. When the side sliding door 2 moves, it will change the propagation path of the surrounding infrared rays, thereby being detected by the infrared sensing device. After the infrared sensing device detects that the door is opened, it will transmit an electrical signal to the air pump connected to it through a preset circuit connection. The air pump starts working after receiving the signal. It inhales and compresses the external air through its own mechanical structure and working principle, and then transports the compressed air to the air storage bin 31 through a pipe or other connection method. A plurality of air inlets 32 are equidistantly provided on the side of the air storage bin 31. The design of these air inlets 32 The design is to allow air to enter the gas storage bin 31 evenly and ensure uniform distribution of gas pressure in the gas storage bin 31. Gas enters the gas storage bin 31 through these air inlets 32. A diaphragm valve 6 is arranged inside the air inlet 32. The working principle of the diaphragm valve 6 is based on the elastic deformation of the diaphragm. When gas enters, the gas pressure will deform the diaphragm and open the valve to allow gas to enter the gas storage bin 31. When the gas pressure in the gas storage bin 31 reaches a certain level, the diaphragm will gradually recover to a certain level under the combined effect of its own elasticity and the gas pressure in the gas storage bin 31, so that the valve is in a state of slow exhaust. This can ensure that the gas pressure in the gas storage bin 31 will not be too high, and at the same time, the gas can be slowly released when needed. As the gas is continuously filled in, the gas storage bin 31 The internal pressure gradually increases, and the top plate 33 is fixedly connected to the inside of the gas storage bin 31 through a plurality of equidistantly arranged elastic mechanisms 34 (such as springs, spiral telescopic tubes or gas struts, etc.). The function of the elastic mechanism 34 is to provide support and reset force for the top plate 33 when the gas pressure changes. When the gas pressure increases to a certain level, the gas will push up the top plate 33. Nut sleeves 35 are fixedly connected to both ends of the top plate 33. In the process of the top plate 33 being lifted up, the nut sleeve 35 will move on the threaded rod 36. Since the nut sleeve 35 and the threaded rod 36 are connected by a ball nut pair, the ball nut pair is a high-precision transmission mechanism that converts rotary motion into linear motion. When the nut sleeve 35 moves up and down, the ball will roll between the threads of the nut sleeve 35 and the threaded rod 36. Thereby, the threaded rod 36 is driven to rotate, and the rotation of the threaded rod 36 drives the rotating rod 45 in the air intake mechanism 4 to rotate. Three baffles 42 are rotatably connected inside the air intake chamber 41 of the air intake mechanism 4. Turbines 43 are fixedly connected at both ends of the baffles 42. Three worms 46 matching the turbines 43 are fixedly connected to the rotating rod 45. When the rotating rod 45 rotates, the turbine 43 is driven to rotate through the meshing transmission of the worm 46 and the turbine 43. The meshing transmission of the worm 46 and the turbine 43 is based on the principle of gear transmission. The worm 46 is equivalent to a screw, and the turbine 43 is equivalent to a gear. When the worm 46 rotates, it drives the turbine 43 to rotate. The two ends of the turbine 43 are also fixedly connected with rotating shafts 44. During the rotation of the turbine 43, the rotating shaft 44 will cause the baffles 42 to unfold.Thus, when the car is not used for a long time, the outside air can enter the air intake chamber 41. The expansion process of the baffle 42 is to rotate the baffle 42 around the connection point between the baffle 42 and the air intake chamber 41 through the rotation of the rotating shaft 44, so as to open the air intake channel. A fragrance mechanism 5 is arranged on the side of the air intake chamber 41. The air entering the air intake chamber 41 will be processed by the fragrance mechanism 5. The fragrance mechanism 5 includes a filter chamber 51 and a plurality of wind wheels 52 rotatably connected to the side thereof. An activated carbon net is arranged inside the filter chamber 51. The activated carbon net uses the adsorption characteristics of activated carbon to filter the air. The activated carbon has a huge specific surface area and can adsorb impurities and harmful gases in the air. When air enters the filter chamber 51, the air will flow on the surface of the activated carbon net, and impurities, harmful gases and odors will be adsorbed by the activated carbon, thereby achieving air filtration and purification. The wind wheel 52 includes a fragrance component 521, and the fragrance component 521 is fixedly connected to the inside of the wind wheel shaft 523. When air enters, it will drive the wind wheel 52 to rotate. When the wind wheel shaft 523 rotates, the fragrance inside the fragrance component 521 is blown out, so that the air entering the car has a pleasant fragrance and is also filtered and purified. The rotation of the wind wheel 52 is based on the power of air flow. When air enters the air intake chamber 41 and flows through the wind wheel 52, the air The flow of air will generate a torque on the wind wheel 52, causing the wind wheel 52 to rotate around its axis. The front end of the straight rod 524 is fixedly connected to the upper convex ring 525 that matches the elastic rod 5213. The straight rod 524 is also movably connected to a lower convex ring 526, and the maximum radius of the lower convex ring 526 is greater than the maximum radius of the upper convex ring 525. When it is necessary to operate the fragrance component 521, such as replacing the fragrance substance, the fragrance rod 5211 is pushed, and the movement of the fragrance rod 5211 will drive the elastic rod 5213 to move together. Since the radius of the lower convex ring 526 is large, when the fragrance rod 5211 moves to a certain extent, the elastic rod 5213 will contact As the fragrance rod 5211 continues to push, the lower convex ring 526 will exert an outward force on the elastic rod 5213, so that the elastic rod 5213 overcomes the engagement with the upper convex ring 525, thereby unlocking the upper convex ring 525 and the tenon 5212 through the lower convex ring 526, so that the fragrance rod 5211 can be taken out of the fragrance component 521, and then the fragrance component 521 can be maintained or the fragrance material can be replaced. After the operation is completed, the fragrance rod 5211 is reinserted, and the elastic rod 5213 will re-engage with the upper convex ring 525 under its own elasticity, so that the fragrance component 521 is re-fixed.
