Description

Technical Field

[0001] This utility model relates to the field of automobile door manufacturing and processing technology, specifically to an electric double door. Background Technology

[0002] With the acceleration of urbanization and the increasing severity of traffic congestion, the demand for small, compact vehicles is gradually increasing. These vehicles not only need to provide efficient transportation solutions in limited urban spaces, but also need to provide passengers with a comfortable and convenient boarding and alighting experience. Although the traditional hinged door design is widely used in various vehicle models, it often encounters problems such as limited opening angle and large external space occupation when opening in narrow spaces, especially in crowded parking lots or streets.

[0003] In addition, the design of traditional car doors usually requires the use of guide rails or other mechanical structures on the outside of the car body to realize the opening and closing of the doors. This not only limits the design freedom of the car body, but also has a certain impact on the aesthetics of the car body.

[0004] Based on the above, the shortcomings of the existing technology can be summarized as follows:

[0005] 1. Low space utilization: Most existing vehicles use outward-opening hinged doors. This design requires a large space to open the door when the vehicle is parked in a narrow space, making it inconvenient for users to get in and out of the vehicle. This design is especially inconvenient in congested urban environments.

[0006] 2. High safety risks: When vehicles are parked on the roadside, traditional door opening methods can easily lead to collisions with pedestrians or other vehicles, increasing the risk of accidents. This poses a potential safety hazard for cyclists and pedestrians.

[0007] 3. Limited Body Design: To accommodate traditional door opening mechanisms, sufficient space must be reserved on the outer side of the vehicle body for installing guide rails or other auxiliary mechanisms. This not only increases the complexity of the body but also limits the designer's creative expression in exterior design, affecting the overall aesthetics of the vehicle.

[0008] Current vehicle door systems on the market have limitations in space utilization, safety, and aesthetic design, making it difficult to fully meet the needs of modern urban dwellers for efficient, convenient, safe, and aesthetically pleasing travel. Therefore, developing a new generation of vehicle door systems that overcomes these shortcomings has become an inevitable trend in the industry. Utility Model Content

[0009] In view of the shortcomings of traditional car doors, such as low space utilization, high safety risks, and limited vehicle body shape, this utility model provides an electric double door that can improve space utilization, has high safety, and does not require the installation of guide rails.

[0010] To achieve the above objectives, the technical solution of this utility model is as follows:

[0011] An electric double door includes a vehicle body frame, a front door, a rear door, and a drive mechanism. A front door connecting assembly is rotatably mounted at one end of the vehicle body frame, and a rear door connecting assembly is rotatably mounted at the other end. Two drive mechanisms are rotatably mounted on opposite sides of the vehicle body frame. The front door connecting assembly includes an upper front door swing arm assembly and a lower front door swing arm assembly. One end of the upper front door swing arm assembly is rotatably connected to the front door, and the other end is rotatably mounted on the vehicle body frame. One end of the lower front door swing arm assembly is rotatably connected to... The front door is connected to the rear door, with one end rotatably mounted on the vehicle frame and connected to a drive mechanism for rotation. The rear door connection assembly includes an upper rear door swing arm assembly and a lower rear door swing arm assembly. One end of the upper rear door swing arm assembly is rotatably connected to the rear door, and the other end is rotatably mounted on the vehicle frame. Similarly, one end of the lower rear door swing arm assembly is rotatably connected to the front door, and the other end is rotatably mounted on the vehicle frame, connected to a drive mechanism for rotation. Each of the lower front and rear door swing arm assemblies is equipped with a drive mechanism.

[0012] Furthermore, the main body of the upper swing arm assembly of the front door is an upper swing arm A. Both ends of the upper swing arm A are rotatably connected to fixed connecting blocks A via a provided rotating shaft. The two fixed connecting blocks A are respectively fixedly connected to the vehicle body frame and the front door. The lower swing arm assembly of the front door includes a lower swing arm A and a fixed connecting block C. One end of the lower swing arm A is rotatably connected to a fixed connecting block B via a provided rotating shaft, and the other end is fixedly connected to a transmission gear A that cooperates with the drive mechanism. The fixed connecting block B is fixedly connected to the front door. The transmission gear is rotatably mounted in the fixed connecting block C via a rotating shaft. The fixed block C is fixedly connected to the vehicle body frame. When the front door is opened or closed, the drive mechanism is activated, cooperating with the drive transmission gear A to rotate. The transmission gear A drives the lower rotating arm A to rotate, and during this process, the upper rotating arm A follows the rotation of the lower rotating arm A, thereby driving the door to open or close. The opening or closing of the front door is achieved by the drive mechanism being activated and the transmission gear A driving the lower rotating arm A and the upper rotating arm A to rotate synchronously. This ensures the smoothness and reliability of the door movement, and eliminates the need for additional structures such as guide rails on the outside of the vehicle body, thus maintaining the simple and smooth appearance of the vehicle body.

[0013] Furthermore, the main body of the upper swing arm assembly of the rear door is an upper swing arm B. Both ends of the upper swing arm B are rotatably connected to fixed connecting blocks D via a provided rotating shaft. The two fixed connecting blocks D are respectively fixedly connected to the vehicle body frame and the rear door. The lower swing arm assembly of the rear door includes a lower swing arm B and a fixed connecting block E. One end of the lower swing arm B is rotatably connected to a fixed connecting block F via a provided rotating shaft, and the other end is fixedly connected to a transmission gear B that cooperates with the drive mechanism. The fixed connecting block F is fixedly connected to the rear door. The transmission gear is rotatably mounted in the fixed connecting block E via a rotating shaft. The fixed block E is fixedly connected to the vehicle body frame. When the rear door is opened or closed, the drive mechanism is activated, cooperating with the drive transmission gear B to rotate. The transmission gear B drives the lower rotating arm B to rotate, and during this process, the upper rotating arm B follows the rotation of the lower rotating arm B, thereby driving the door to open or close. The opening or closing of the door is achieved by the drive mechanism being activated and the transmission gear B driving the lower rotating arm B and the upper rotating arm B to rotate synchronously. This ensures the smoothness and reliability of the door movement, and eliminates the need for additional structures such as guide rails on the outside of the vehicle body, thus maintaining the simple and smooth appearance of the vehicle body.

[0014] Furthermore, the ends of the upper and lower rotating arms B that connect to the rear door are both arc-shaped rods that fit the rear door structure. The fact that the upper and lower rotating arms B are arc-shaped rods that fit the rear door structure ensures optimal connection stability and smooth movement, thus optimizing the structural motion rationality.

[0015] Furthermore, the drive mechanism includes a motor and a reduction gear set, wherein the reduction gear set is rotatably mounted on the vehicle body frame; the motor is fixedly mounted on the vehicle body frame, and the output shaft of the motor is fixedly connected to a worm gear, which meshes with the reduction gear set. The front door lower control arm assembly and the rear door lower control arm assembly respectively mesh with the reduction gear set of their respective drive mechanisms. After the motor starts, it drives the worm gear to rotate, and then the worm gear meshes with the reduction gear set to transmit power. Finally, the power is transmitted to the front door lower control arm assembly or the rear door lower control arm assembly through the reduction gear set, thereby driving the front door lower control arm assembly or the rear door lower control arm assembly to rotate, realizing the opening and closing operation of the front door or the rear door.

[0016] Furthermore, the reduction gear set includes a double gear A and a double gear B, with a rotating shaft rotatably connected between the double gear A and the double gear B. The rotating shaft is fixedly connected to the vehicle frame. The lower gear of the double gear A meshes with a worm gear, and the upper gear meshes with the lower gear of the double gear B. The upper gear of the double gear B meshes with the lower swing arm assembly of the front door or the lower swing arm assembly of the rear door. When the car door needs to be opened or closed, the drive mechanism is activated, driving the double gear A to rotate via the worm. Since the upper and lower gears of double gear A mesh with the worm and the lower gear of double gear B respectively, this rotational motion is transmitted to double gear B. Subsequently, the upper gear of double gear B transmits the rotational force to the front door lower swing arm assembly or the rear door lower swing arm assembly. The smooth opening or closing of the car door is achieved through the four-bar linkage. Throughout the process, the rotating shaft ensures the stable rotation of double gear A and double gear B on the vehicle frame, maintaining the reliability of the transmission system. The reduction gears not only effectively reduce the impact that may be generated when the drive mechanism directly acts on the car door, but also achieve reasonable power distribution, making the door movement smoother and quieter.

[0017] How to use:

[0018] The front and rear doors operate on the same principle, using a four-bar linkage. The vehicle frame is considered the fixed first link, the upper and lower front door swing arms are considered the rotatable second and third links respectively, and the front door itself is considered the driven fourth link. Similarly, the vehicle frame is considered the fixed first link, the upper rear door swing arm assembly and the lower front door swing arm are considered the rotatable second and third links respectively, and the rear door itself is considered the driven fourth link. When a front or rear door opens or closes, the corresponding drive mechanism rotates the third link. This rotation simultaneously pulls the second and fourth links, causing the front or rear door to open or close.

[0019] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0020] 1. This utility model, by adopting a side-sliding four-bar linkage driven front and rear door design, improves the vehicle's practicality in narrow spaces while ensuring passengers can get on and off the vehicle conveniently and safely. It also significantly reduces the space occupied by the doors when they are open, making it particularly suitable for congested urban environments. Furthermore, it effectively avoids the safety hazards of collisions with pedestrians or other vehicles that may occur with traditional hinged doors. In addition, by eliminating the guide rail design on the outside of the vehicle body, this solution not only makes the vehicle's appearance simpler and smoother, giving designers greater creative freedom, but also enhances the overall aesthetics of the vehicle.

[0021] 2. The opening and closing of the front and rear doors of this utility model is driven by a drive mechanism, which ensures the smoothness and reliability of the door movement and eliminates the need for additional structures such as guide rails on the outside of the vehicle body, maintaining the simple and smooth appearance of the vehicle body. The drive mechanism drives the reduction gear through the worm gear of the motor, which has a compact structure, occupies little space, and provides smooth and reliable transmission. The rotating shaft of the reduction gear set ensures the stable rotation of the double gear A and double gear B on the vehicle body frame, maintaining the reliability of the transmission system. This not only effectively reduces the impact that may be generated when the drive mechanism directly acts on the door, but also achieves reasonable power distribution, making the door movement smoother and quieter.

Detailed Implementation

[0030] The present invention will be further described below with reference to the accompanying drawings.

[0031] Example 1: An electric double door includes a vehicle frame 1, a front door 2, a rear door 3, and a drive mechanism 4. One end of the vehicle frame 1 is rotatably mounted with a connecting assembly for the front door 2, and the other end is rotatably mounted with a connecting assembly for the rear door 3. There are two drive mechanisms 4, rotatably mounted on the vehicle frame 1 on either side. The front door connecting assembly includes an upper front door swing arm assembly 5 and a lower front door swing arm assembly 6. One end of the upper front door swing arm assembly 5 is rotatably connected to the front door 2, and the other end is rotatably mounted on the vehicle frame 1. One end of the lower front door swing arm assembly 6 is rotatably connected to the front door 2. One end of the rear door is rotatably connected to the front door 2, and the other end is rotatably mounted on the vehicle body frame 1. It is also connected to the drive mechanism 4 and driven to rotate by the drive mechanism 4. The rear door connecting assembly includes an upper rear door swing arm assembly 7 and a lower rear door swing arm assembly 8. One end of the upper rear door swing arm assembly 7 is rotatably connected to the rear door 3, and the other end is rotatably mounted on the vehicle body frame 1. The lower rear door swing arm assembly 8 is rotatably connected to the front door 2, and the other end is rotatably mounted on the vehicle body frame 1. It is also connected to the drive mechanism 4 and driven to rotate by the drive mechanism 4.

[0032] The front door 2 and rear door 3 operate on the same principle, using a four-bar linkage. The vehicle frame 1 is considered the fixed first link, the upper swing arm assembly 5 of the front door and the lower swing arm of the front door 2 are considered the rotatable second and third links, respectively, and the front door 2 is considered the driven fourth link. Similarly, the vehicle frame 1 is considered the fixed first link, the upper swing arm assembly 7 of the rear door and the lower swing arm of the front door 2 are considered the rotatable second and third links, respectively, and the rear door 3 is considered the driven fourth link. When the front door 2 or rear door 3 opens or closes, the corresponding drive mechanism 4 drives the third link to rotate. During the rotation of the third link, the second and fourth links are simultaneously pulled to rotate, thus opening or closing the front door 2 or rear door 3.

[0033] Example 2: The difference from Example 1 is that the main body of the upper swing arm assembly 5 of the front door is an upper swing arm A51. The two ends of the upper swing arm A51 are respectively rotatably connected to fixed connecting blocks A52 through a provided rotating shaft 9. The two fixed connecting blocks A52 are respectively fixedly connected to the vehicle frame 1 and the front door 2. The lower swing arm assembly 6 of the front door includes a lower swing arm A61 and a fixed connecting block C62. One end of the lower swing arm A61 is rotatably connected to a fixed connecting block B63 through a provided rotating shaft 9, and the other end is fixedly connected to a transmission gear A64 that cooperates with the drive mechanism 4. The fixed connecting block B63 is fixedly connected to the front door 2. The transmission gear is rotatably installed in the fixed connecting block C62 through a rotating shaft. The fixed block C62 is fixedly connected to the vehicle frame 1. When the front door 2 is opened or closed, the drive mechanism 4 is activated, and the drive transmission gear A64 rotates. The transmission gear A64 drives the lower rotating arm A61 to rotate. During this process, the upper rotating arm A51 rotates along with the lower rotating arm A61, thereby driving the door to open or close. The opening or closing of the front door 2 is achieved by the drive mechanism 4 being activated and the transmission gear A64 driving the lower rotating arm A61 and the upper rotating arm A51 to rotate synchronously. This ensures the smoothness and reliability of the door movement, and eliminates the need for additional structures such as guide rails on the outside of the vehicle body, thus maintaining the simple and smooth appearance of the vehicle body.

[0034] The main body of the upper swing arm assembly 7 of the rear door is an upper swing arm B71. Both ends of the upper swing arm B71 are rotatably connected to fixed connecting blocks D72 via a provided rotating shaft 9. The two fixed connecting blocks D72 are fixedly connected to the vehicle frame 1 and the rear door 3, respectively. The lower swing arm assembly 8 of the rear door includes a lower swing arm B81 and a fixed connecting block E82. One end of the lower swing arm B81 is rotatably connected to a fixed connecting block F83 via a provided rotating shaft 9, and the other end is fixedly connected to a transmission gear B84 that cooperates with the drive mechanism 4. The fixed connecting block F83 is fixedly connected to the rear door 3. The transmission gear is rotatably mounted in the fixed connecting block E82 via a rotating shaft. The fixed block E82 is fixedly connected to the vehicle frame 1. When the rear door 3 is opened or closed, the drive mechanism 4 is activated, cooperating with the drive transmission gear B84 to rotate. The transmission gear B84 drives the lower rotating arm B81 to rotate. During this process, the upper rotating arm B71 rotates along with the lower rotating arm B81, thereby driving the door to open or close. The opening or closing of the door is achieved by the drive mechanism 4 being activated and the transmission gear B84 driving the lower rotating arm B81 and the upper rotating arm B71 to rotate synchronously. This ensures the smoothness and reliability of the door movement and eliminates the need for additional structures such as guide rails on the outside of the vehicle body, thus maintaining the simple and smooth appearance of the vehicle body.

[0035] Example 3: The difference from Example 2 is that the ends of the upper swing arm B71 and the lower swing arm B81 that connect to the rear door 3 are both arc-shaped rods that fit the structure of the rear door 3. The arc-shaped rods of the upper swing arm B71 and the lower swing arm B81, which fit the structure of the rear door 3, ensure optimal connection stability and smooth movement, thus optimizing the structural motion rationality.

[0036] The drive mechanism 4 includes a motor 41 and a reduction gear set, wherein the reduction gear set is rotatably mounted on the vehicle frame 1; the motor 41 is fixedly mounted on the vehicle frame 1, and the output shaft of the motor 41 is fixedly connected to a worm gear 44, which meshes with the reduction gear set. The front door lower control arm assembly 6 and the rear door lower control arm assembly 8 respectively mesh with the reduction gear set of their respective drive mechanisms 4. After the motor 41 starts, it drives the worm gear 44 to rotate, and then the worm gear 44 meshes with the reduction gear set to transmit power. Finally, the power is transmitted to the front door lower control arm assembly 6 or the rear door lower control arm assembly 8 through the reduction gear set, thereby driving the front door lower control arm assembly 6 or the rear door lower control arm assembly 8 to rotate, realizing the opening and closing operation of the front door 2 or the rear door 3.

[0037] The reduction gear set includes a double gear A42 and a double gear B43. A rotating shaft 9 is rotatably connected between the double gears A42 and B43. The rotating shaft 9 is fixedly connected to the vehicle frame 1. The lower gear of the double gear A42 meshes with a worm gear, and the upper gear meshes with the lower gear of the double gear B43. The upper gear of the double gear B43 meshes with the lower swing arm assembly 6 of the front door or the lower swing arm assembly 8 of the rear door. When the door needs to be opened or closed, the drive mechanism 4 is activated, driving the double gear A42 to rotate via the worm. Since the upper and lower gears of the double gear A42 mesh with the worm and the lower gear of the double gear B43 respectively, this rotational motion is transmitted to the double gear B43. Subsequently, the upper gear of the double gear B43 transmits the rotational force to the front door lower swing arm assembly 6 or the rear door lower swing arm assembly 8. The smooth opening or closing of the door is achieved through the four-bar linkage. Throughout the process, the rotating shaft 9 ensures the stable rotation of the double gears A42 and B43 on the vehicle frame 1, maintaining the reliability of the transmission system. The reduction gears not only effectively reduce the impact that may be generated when the drive mechanism 4 directly acts on the door, but also achieve reasonable power distribution, making the door movement smoother and quieter.
