[0023] The specific embodiments of the present invention will be described in more detail below with reference to the drawings and by describing the optimal embodiment.
[0024] The present invention provides a dual-mode vehicle door electric system 3, which includes a hinge assembly to which a connecting mechanism and a drive mechanism are connected. By using the hinge assembly, connecting mechanism and drive mechanism in combination, the present invention makes it possible for a vehicle door 1 to which the electric system 3 is attached to have two types of door opening methods, and the vehicle door 1 is easily used in the actual opening process.
[0025] The vehicle door electric system 3 disclosed in the present invention is an electric system mainly used for opening and closing vehicle doors 1.
[0026] The vehicle door electric system 3 disclosed in the present invention mainly comprises a hinge assembly, in which the hinge assembly is essentially a hinge assembly for a vehicle door 1 for a scissor door, where a conventional scissor door hinge assembly may be used, or a hinge assembly described below in the present invention may be used, one function of the hinge assembly is to perform a basic connecting function, and another function is to enable the rotational opening of the vehicle door 1 (scissor door opening).
[0027] On the one hand, the connecting mechanism and the drive mechanism are connected to the hinge assembly. In the present invention, the main function of the connecting mechanism is to connect the vehicle door 1 to the hinge assembly. At the same time, the connecting mechanism of the present invention is also used as a rotating part, which allows the vehicle door 1 to rotate around the connecting mechanism during subsequent use, thereby facilitating the side opening operation of the vehicle door 1.
[0028] The drive mechanism is used as a drive component to facilitate the automatic opening and closing of the vehicle door 1. In the present invention, as shown in Figures 1 to 3, the drive mechanism includes a side-opening drive mechanism 39 and a rotor blade drive mechanism 33. The side-opening drive mechanism 39 is generally an electric side-opening actuator. By positioning the electric side-opening actuator inside the vehicle door 1, it extends from the front end of the vehicle door 1, and the subsequent self-extending and retracting motion of the electric side-opening actuator realizes side-opening drive for the vehicle door 1 (see Figures 3 and 5 for side-opening drive). In the present invention, one end of the electric side-opening actuator is pressed against the side assembly 2 (where (See Figure 11) The other end is connected to the vehicle door 1 (see Figure 9), and the extension of the electric side-opening actuator enables the opening of the vehicle door 1. Furthermore, in order to facilitate the subsequent operation of opening the rotor blades of the vehicle door 1 in this invention (see Figures 2 and 4 for the rotor blade opening operation), the end of the electric side-opening actuator is not directly connected to the side assembly 2, but rather acts on the side assembly 2 by the first extension plate 322 in the vehicle door component 32. This installation avoids the problem of the electric side-opening actuator being connected to the side assembly 2 and affecting the opening of the rotor blades of the vehicle door 1.
[0029] The rotor blade drive mechanism 33 primarily applies rotational force to the hinge assembly, thereby causing the vehicle door component 32 in the hinge assembly to rotate around the vehicle body component 31, which in turn drives the vehicle door 1 to rotate around the vehicle body component 31, and further enables the opening of the rotor blades of the vehicle door 1.
[0030] Furthermore, in the present invention, the connection mechanism is used to connect to the vehicle door 1, facilitating the connection between the electric system 3 and the vehicle door 1; the side-opening drive mechanism 39 can drive the vehicle door 1 to rotate around the hinge assembly, facilitating the side-opening operation of the vehicle door 1; and the rotor blade drive mechanism 33 can drive the rotation of the vehicle door 1 by the hinge assembly, facilitating the rotor blade opening operation of the vehicle door 1.

[0034] As shown in Figures 1 and 7, in the present invention, the first locking portion 37 mainly includes a first lock catch 371 connected to the side of the vehicle door component 32 adjacent to the side assembly 2 and a first lock body 372 connected to the side assembly 2, and the second locking portion 36 includes a second lock catch 361 connected to the vehicle door component 32, specifically connected to the side of the vehicle door component 32 adjacent to the vehicle door 1, and installed on the second extension plate 323 in actual implementation, and a second lock body 362 connected to the vehicle door 1.
[0035] Furthermore, in the present invention, the vehicle door component 32 is connected to the vehicle body component 31 via a rotating component 4. The installation of the rotating component 4 is primarily for connecting the vehicle door component 32 to the vehicle body component 31, and at the same time, it also enables the rotation of the vehicle door component 32 on the vehicle body component 31.
[0036] Furthermore, in the present invention, the rotating part 4 includes a first rotating part 4 and a second rotating part 4. By installing the first rotating part 4 and the second rotating part 4, a three-dimensional spatial link structure is formed between the vehicle door part 32 and the vehicle body part 31, the link 42, and the rotating rod 41, thereby realizing an opening method in which the vehicle door 1 forms a scissor door.
[0037] As shown in Figure 1, in the present invention, the first rotating component includes a rotating rod 41, one end of which is rotatably connected to a vehicle body component 31 and the other end of which is rotatably connected to a vehicle door component 32, and as shown in Figures 1 and 14, in the present invention, the rotating rod 41 is connected to the vehicle body component 31 by a first pivot shaft assembly 301, the first pivot shaft assembly 301 includes two sets of first assembly plates installed perpendicularly to the vehicle body component 31, and a first shaft that passes through the two sets of first assembly plates and the rotating rod 41, and the rotating rod 41 is assembled between the two sets of first assembly plates, and in the present invention, the vehicle door component 32 is riveted to the rotating rod 41, and at the same time the vehicle door component 32 is riveted to the vehicle door component 32 via the pivot shaft, and the vehicle door component 32 can rotate around the central axis of the rotating rod 41.
[0038] Simultaneously, as shown in Figure 1, in the present invention, the second rotating component includes a link 42, one end of which is rotatably connected to a vehicle door component 32, and the other end of which is connected to a vehicle body component 31 by a ball head mechanism 43. As shown in Figure 14, the connection method between the link 42 and the vehicle door component 32 can also be similar to that of the first pivot shaft assembly 301 described above.
[0039] The connection between link 42 and vehicle door component 32 is achieved by a ball head mechanism 43. As shown in Figures 1 and 14, the ball head mechanism 43 mainly includes a ball socket case 302 installed on the vehicle body component 31. A ball socket structure is provided in the ball socket case 302, and a ball head is provided at one end of link 42 assembled to the ball socket case 302. The ball head is installed within the ball socket structure and rotates spherically within the ball socket structure to form a spherical sub-bulb. A ball head bush is injected onto the ball head, and here, the ball head bush tightly connects with the ball head, making the ball head more wear-resistant.
[0040] Furthermore, as shown in Figure 1, in the present invention, the locking mechanism further includes a lock control component 38, and in the present invention, the installation of the lock control component 38 can control the unlocking operation of the first locking part 37 or the second locking part 36 as needed.
[0041] As shown in Figure 7, in the present invention, the lock control component 38 includes a turntable 382, and a rotation drive component is connected to the turntable 382 to drive the rotation of the turntable 382, and the rotation drive component drives the rotation of the turntable 382 to control the unlock operation of the first locking part 37 and the second locking part 36, and the turntable 382 is connected to the first locking part 37 or the second locking part 36 via a cable 3801, and in the present invention, the turntable 382 is used as a connecting component and a control component, and the rotation drive component may be a drive motor 383 or a gas drive component, and in the present invention In this invention, the rotating drive component can drive the rotation of the turntable 382 and, in combination with the cable 3801, realizes the unlock operation of the first locking part 37 or the second locking part 36. In this invention, one end of the cable 3801 is connected to the turntable 382 and the other end is connected to the lock body of the first locking part 37 or the second locking part 36. By driving the corresponding lock body via the cable 3801, the lock body and the corresponding lock catch are separated, thereby realizing the corresponding unlock operation, and allowing for easy lateral or rotary opening of the vehicle door 1 as needed during subsequent use.
[0042] As shown in Figures 7 and 8, in the present invention, the rotational drive component may include a drive motor 383, a worm is provided on the output shaft of the drive motor 383, a worm wheel is provided on the turntable 382, and the worm wheel worm structure 384 enables the drive of the drive motor 383 to rotate the turntable 382.
[0043] Furthermore, in the present invention, the cable 3801 mainly includes a cable core, a cable head 3802 is provided at the end of the cable core, and a cable sheath is provided outside the cable core.
[0044] Furthermore, in the present invention, the turntable 382 is connected to the first locking part 37 and the second locking part 36 via the cable 3801, respectively. Based on this setup, the turntable 382 can control the unlocking operation of the first locking part 37 or the second locking part 36, reducing the use of lock control components 38, i.e., reducing the number of lock control components 38, thereby saving costs.
[0045] Simultaneously, in the present invention, the cable 3801 is connected to the turntable 382 by an adjustment component, and in the present invention, the installation of the adjustment component has two functions: one is to facilitate the connection between the cable 3801 and the turntable 382, and the other is to prevent the rotation of the turntable 382 from simultaneously controlling the synchronous unlocking of the first locking part 37 and the second locking part 36 during subsequent use.
[0046] As shown in Figure 8, in the present invention, the adjustment part includes an adjustment arc groove 3821 and a side communication groove 3822 installed on the turntable 382, the adjustment arc groove communicates with the side of the turntable 382 via the side communication groove 3822, the cable head 3802 of the cable 3801 is located in the adjustment arc groove 3821, and based on the above design, stable connection of the cable 3801 to the turntable 382 can be facilitated, in the present invention the adjustment arc groove 3821 is an arc groove structure and the length of the adjustment arc groove 3821 is the length of the cable head By making the dimensions larger than those of 3802, the cable head 3802 can move within the adjustment arc groove 3821, while the side communication groove 3822 is primarily for facilitating the drilling of the cable core and avoiding mounting interference with the turntable 382. At the same time, in this invention, the cable sheath of the cable 3801 is located outside the turntable 382, and in this invention, the cable sheath is fitted into the lock housing 381, and such installation facilitates driving to the subsequent cable core and enables subsequent unlocking operations.
[0047] As can be seen from the above, the lock control component 38 of the present invention further includes a lock housing 381, in which the turntable 382, the rotation drive component and the adjustment component are all installed within the lock housing 381, the cable 3801 passes through the lock housing 381 and extends to the turntable 382, the cable sheath of the cable 3801 is fitted into the outer wall of the lock housing 381, the lock housing 381 serves to limit the position of the end, and the lock housing 381 also facilitates subsequent installation and assembly of the lock control component 38, as shown in Figures 8 to 10 to 12, during subsequent installation, the lock control component 38 can be connected to the side assembly 2 by the lock housing 381, facilitating the placement and installation of the lock control component 38 on the entire vehicle.
[0048] Furthermore, as shown in Figure 1, in the present invention, the vehicle door component 32 includes a frame body 321, and the frame body 321 is the main structure of the vehicle door component 32. In the present invention, the structure and shape of the frame body 321 can be designed as necessary, as long as strength is ensured and interference with adjacent components is avoided.
[0049] Simultaneously, as shown in Figures 1, 13, and 16 (Figure 16 is a local schematic diagram of Figure 13), in the present invention, the frame body 32 further includes a first extension plate 322 and a second extension plate 323, the first extension plate 322 and the second extension plate 323 and the frame body 321 are installed intersectingly, the first extension plate 322 is used to connect to the side opening drive mechanism 39, and the second extension plate 323 is used to connect to the second locking part 36. In the present invention, the first extension plate 322 and the second extension plate 323 may generally be installed perpendicular to the frame body 321, and in subsequent use, by arranging the first extension plate 322 and the second extension plate 323 on the side of the side assembly 2, they can be used to a certain extent for lateral positioning during the assembly of the vehicle door parts 32, thereby ensuring the accuracy of the subsequent assembly of the vehicle door parts 32.
[0050] Another main function of the first extension plate 322 and the second extension plate 323 is to facilitate the connection and positioning of the vehicle door 1, which essentially facilitates the attachment and connection of the side-opening drive mechanism 39 and the second locking part 36 to the hinge assembly, facilitates the interlocking of the vehicle door 1 and the vehicle door component 32 during subsequent movements, and further ensures the opening of the rotor blades of the vehicle door 1.
[0051] Furthermore, as shown in Figure 1, in the present invention, the vehicle door connecting component 34 is connected to the vehicle door component 32 by a pivot support portion 35, the pivot support portion 35 includes a lower support block 352 installed on the vehicle door component 32 and an upper support block 351 installed on the vehicle door connecting component 34, the upper support block 351 is connected to the lower support block 352 via a pivot pin shaft, the rotor blade drive mechanism 33 includes a first drive mechanism and a second drive mechanism, the first drive mechanism and the second drive mechanism are distributed at intervals on the vehicle door component 32, in the present invention, the installation of the pivot support portion 35 facilitates the connection between the vehicle door connecting component 34 and the vehicle door component 32, and also facilitates the connection between the subsequent vehicle door 1 and the vehicle door component 32, and at the same time, the pivot support portion 35 serves as the pivot base and pivot point when the subsequent vehicle door 1 is opened to the side, and in the present invention, multiple pivot support portions 35 can be installed at intervals along the vertical direction, and generally two sets are sufficient.
[0052] Furthermore, in this invention, the side-opening drive mechanism 39 can be used to open the vehicle door 1, and the rotor blade drive mechanism 33 can be used to open the rotor blade of the vehicle door 1. In the case of opening the rotor blade of the vehicle door 1, the steps for opening the vehicle door 1 are to first open the first locking part 37, the second locking part 36 hold the lock, then release the vehicle door lock, and then activate the rotor blade drive mechanism 33 to rotate the vehicle door component 32, thereby driving the vehicle door 1 to rotate upward and perform rotor blade motion, thereby achieving the opening of the rotor blade of the vehicle door 1. The steps for closing the vehicle door 1 are to activate the rotor blade drive mechanism 33 again, and rotate the vehicle door component 32, thereby driving the vehicle door 1 to rotate downward and perform rotor blade motion, thereby achieving the closing of the rotor blade of the vehicle door 1. In this case, after the vehicle door 1 is closed, the first locking part 37 is locked and the second locking part 36 remains locked. In the case of a side-opening operation of the vehicle door 1, the steps of the vehicle door 1 opening operation are as follows: the first locking part 37 holds the lock and the second locking part 36 is released, then the vehicle door lock is released, followed by activating the side-opening drive mechanism 39, which drives the vehicle door 1 to rotate outwards, thereby achieving the side-opening operation of the vehicle door 1. In the vehicle door 1 closing operation, the steps of the side-opening drive mechanism 39 are as follows: the side-opening drive mechanism 39 is activated, which drives the vehicle door 1 to rotate inwards until it reaches a set closed position, then the vehicle door lock completes its suction closing, then the first locking part 37 holds the lock and the second locking part 36 is locked.
[0053] In other words, during the process of opening the rotor blades of the vehicle door 1, the vehicle door 1 opening operation step controls the first locking part 37 to release the rotation lock of the vehicle door component 32 on the vehicle body component 31, and the second locking part 36 to lock the rotation of the vehicle door connecting component 34 on the vehicle door component 32, thereby controlling the release of the vehicle door lock and controlling the activation of the rotor blade drive mechanism 33, thereby driving the vehicle door component 32 to rotate so that the vehicle door 1 rotates upward and performs rotor blade motion. The vehicle door 1 closing operation step controls the activation of the rotor blade drive mechanism 33, thereby driving the vehicle door component 32 to rotate so that the vehicle door rotates downward and performs rotor blade motion until the vehicle door 1 is closed, the first locking part 37 to lock the rotation of the vehicle door component 32 on the vehicle body component 31, and the second locking part 36 to lock the rotation of the vehicle door connecting component 34 on the vehicle door component 32. In the process of opening the vehicle door 1, the opening operation step of the vehicle door 1 controls the first locking part 37 to lock the rotation of the vehicle door component 32 on the vehicle body component 31, and the second locking part 36 to release the lock on the rotation of the vehicle door connecting component 34 on the vehicle door component 32, thereby controlling the release of the vehicle door lock and controlling the activation of the side opening drive mechanism 39, which in turn drives the vehicle door connecting component 34 to rotate so that the vehicle door 1 rotates out of the vehicle. The closing operation step of the vehicle door 1 controls the activation of the side opening drive mechanism 39, which in turn drives the vehicle door connecting component 34 to rotate so that the vehicle door rotates inward until it reaches a set closed position, thereby controlling the closing of the vehicle door lock, which in turn controls the first locking part 37 to lock the rotation of the vehicle door component 32 on the vehicle body component 31, and the second locking part 36 to lock the rotation of the vehicle door connecting component 34 on the vehicle door component 32.
[0054] As can be seen from the above operating method, the electric system 3 disclosed in the present invention can realize lateral and rotary blade opening operations of the vehicle door 1, thereby increasing the scope of application of the present invention.
[0055] Furthermore, in the present invention, when the rotor blades of the vehicle door 1 are opened, the side-opening drive mechanism 39 is energized, and as shown in Figure 15, a buffer block is provided in the second locking part 36. This setup reduces vibration when the rotor blades of the vehicle door 1 are opened. When the rotor blades of the vehicle door 1 are opened, the side-opening drive mechanism 39 is energized, putting it into a pre-operation state. This setup ensures that the drive end of the side-opening drive mechanism 39 receives force and remains stable, thereby avoiding vibration caused by a gap between the drive end and adjacent parts, and further preventing vibration when the vehicle door 1 moves upward.
[0056] Similarly, in the case of a side-opening operation of the vehicle door 1, the rotor blade drive mechanism 33 is required to be energized when the vehicle door 1 is opened, and a buffer block is provided in the first locking part 37.
[0057] The present invention relates to a vehicle comprising a side assembly 2 and a vehicle door 1, wherein the vehicle door 1 is connected to the side assembly 2 by an electric system 3, and the electric system 3 is connected to the side assembly 2 of the vehicle body, and the present invention states that with such an installation, the vehicle door 1 has two types of door opening methods, thereby giving the vehicle door 1 disclosed by the present invention a wider range of applications.
[0058] In the present invention, the electric system 3 is mainly connected to the side assembly 2 of the vehicle body, the vehicle body components 31 in the electric system 3 are fixedly connected to the vehicle body, the vehicle body connection components are used to connect to the vehicle door 1, and the hinge assembly is connected to a combination of a connection mechanism and a drive mechanism, thereby realizing two types of opening methods for the vehicle door 1.
[0059] At the same time, in the present invention, the side assembly 2 is provided with a plurality of relief grooves, which are installed in various ways, mainly to avoid mounting interference between the electric system 3 and the side assembly 2.
[0060] In the present invention, at least two relief grooves are provided on the side of the side assembly 2 adjacent to the vehicle door 1, and these two relief grooves are used to accommodate the first extension plate 322 and the second extension plate 323 in the electric system 3.
[0061] Furthermore, in the present invention, the vehicle further includes a control system including a detection module, the control module being connected to the detection module, and the execution module being connected to the control module. The detection module may be a radar or camera for depth measurement and is mainly used for recognizing the environment around the vehicle body and recognizing whether or not there are obstacles around the vehicle door 1. The control module is mainly used to receive signals transmitted from the detection module, perform recognition processing, and issue commands. The control module may be a vehicle computer. The execution module is mainly used to perform corresponding operations based on commands transmitted from the control module. The execution module may be a side-opening drive mechanism 39, a rotor blade drive mechanism 33, and a rotation drive component, and is mainly used in a structure that corresponds to opening and closing the vehicle door 1. The present invention makes it possible to realize intelligent opening and closing operations of the vehicle door 1 by installing the control system.
[0062] At the same time, in order to facilitate the intelligent opening of the vehicle door 1, the control system further includes an input module, which may be one or more of the following, or a combination thereof: voice input, entity switch switching, and large screen switch switching.
[0063] Furthermore, in the present invention, an initial support mechanism is provided on the side assembly 2, which is an auxiliary support structure that mainly prevents the vehicle door 1 from sagging due to gravity and at the same time reduces the force on the hinge assembly. In the present invention, the initial support mechanism includes a support position limiting block installed on the side assembly 2, and when the vehicle door 1 is in the closed position, the vehicle door component 32 is pressed against the support position limiting block, which may be connected to the side assembly 2 by bolts. With this installation, the vehicle door component 32 is supported by the support position limiting block, which reduces the force on the rotating component 4 and helps extend the service life of the rotating component 4.
[0064] At the same time, in the present invention, in order to facilitate combined positioning, a position-limiting groove is provided in the vehicle door component 32, and the vehicle door component 32 is pressed against the support position-limiting block by the position-limiting groove. At the same time, in order to increase the contact area between the support position-limiting block and the vehicle door component 32, the support position-limiting block may be designed as a stepped block, and the position-limiting groove in the vehicle door component 32 may also be designed as a stepped structure.
[0065] At the same time, in order to avoid interference, the support position limiting block of the present invention is installed at one end of the vehicle door component 32 that is close to the vehicle head.
[0066] Examples are as follows:
[0067] The electric system 3 disclosed in the present invention can primarily realize the electric opening of the rotating blades and electric side opening of the vehicle door 1, and can realize the coexistence of two types of modes, and can realize electric switching between the two types of modes by the lock control component 38.
[0068] As shown in Figure 1, the electric system 3 disclosed by the present invention mainly includes a vehicle body component 31, a vehicle door component 32, a vehicle door connecting component 34, a rotating rod 41, a link 42, a lock control component 38, a side-opening drive mechanism 39, a rotor blade drive mechanism 33, a first locking part 37, and a second locking part 36.
[0069] The side-opening drive mechanism 39 disclosed in the present invention mainly includes an electric side door actuator, and the rotary-wing drive mechanism 33 mainly includes an electric stay and an air stay installed at both ends of the vehicle door component 32.
[0070] As shown in Figures 7 and 15, the first locking portion 37 includes a first lock catch 371 used for locking the side assembly 2 of the vehicle door component 32, and the second locking portion 36 includes a second lock catch 361 used for locking the vehicle door component 32 of the vehicle door 1.
[0071] The opening method of vehicle door 1 will be explained below in conjunction with Figure 6.
[0072] In electric rotary-wing door mode (explained in self-adaptive mode), when vehicle door 1 is opened, if vehicle door 1 receives a door open signal, the radar determines the opening method of vehicle door 1. If it determines that the upward distance is relatively large and that the rotary-wing door can be opened, it first opens the first locking part 37 (i.e., lock A), the second locking part 36 (i.e., lock B) holds the lock, then releases the vehicle door lock, and subsequently the electric stay is electrically shortened, driving vehicle door 1 to rotate upward and perform a rotary-wing motion. The stay also has a built-in hole counting function that records the movement position of vehicle door 1 in real time, and stops the movement when the set number of holes is reached, in which case the rotary-wing door completes its full opening motion.
[0073] Closing of vehicle door 1: When vehicle door 1 receives a door closing signal, the operation sequence is as follows: the electric stay extends electrically, vehicle door 1 is driven to rotate downward and perform a rotor motion, and the stay has a built-in hole counting function that records the movement position of vehicle door 1 in real time. When the set number of holes is reached, the movement stops, in which case the vehicle door lock completes the suction closing, then the first locking part 37 performs the locking operation, and the second locking part 36 holds the lock, in which case the rotor door completes the full closing motion.
[0074] In the electric side-open mode (explained in self-adaptive mode), when vehicle door 1 is opened, the radar determines the opening method of vehicle door 1. If it determines that the side distance is relatively large and electric side-opening is possible, the operation sequence is as follows: the first locking part 37 holds the lock, the second locking part 36 is released, then the vehicle door lock is released, and subsequently the stay of the electric side-open door actuator is electrically extended, driving vehicle door 1 to rotate outwards. A hole counting function is also built in, recording the movement position of vehicle door 1 in real time. When the set number of holes is reached, the movement stops, and in this case, the electric side-open door completes its full opening motion.
[0075] Closing of vehicle door 1: When vehicle door 1 receives a door closing signal, the operation sequence is as follows: the stay of the electric door actuator is electrically shortened, and vehicle door 1 is driven to rotate inward and perform rotational motion. The stay also has a hole counting function built in, which records the movement position of vehicle door 1 in real time. When the set number of holes is reached, the movement stops, in which case the vehicle door lock completes its suction closing. Next, the first locking part 37 holds its locking position, and the second locking part 36 is locked, in which case the rotary door completes its full closing motion.
[0076] In this invention, the electric rotor blade is switched by releasing the first locking part 37 and holding the second locking part 36 in place, and then the electric stay performs electric extension and retraction operations, thereby raising and lowering the vehicle door rotor blade.
[0077] Switching between electric side opening: The first locking part 37 holds the lock, the second locking part 36 is released, and then the drive arm of the electric side opening actuator performs an electric extension and retraction operation, thereby enabling electric rotational opening and closing of the vehicle door 1 side door.
[0078] The present invention enables the control of the first locking section 37 and the second locking section 36 by a motor through the installation of a locking control component 38. There are a total of three possible states for the combination of the first locking section 37 and the second locking section 36, all of which can be realized by this module, specifically as follows (see Table 1 for details).
[0079] [Table 1]
[0080] This lock control component 38 includes a motor, a worm wheel worm drive, and a turntable 382, which are all rotational drive components.
[0081] Rotary blade door switching: When the motor drives the turntable 382 to rotate in the reverse direction, the turntable 382 drives the movement of the cable 3801, which opens the first locking part 37 and holds the second locking part 36 locked, thereby enabling the switching of the electric rotary blade door.
[0082] Switching of the side-opening door: When the motor drives the turntable 382 to rotate in the forward direction, the turntable 382 drives the movement of the cable 3801, which opens the second locking part 36 and maintains the locked state of the first locking part 37, thereby enabling the switching of the motorized side-opening door.
[0083] Closed state: The motor is not moving, the first locking part 37 and the second locking part 36 maintain the locked state, and the vehicle door 1 is in the locked state.
[0084] At the same time, the present invention requires the addition of a buffer block to the second locking portion 36 and the application of power to the electric door actuator when the rotor blades of the vehicle door 1 are opened, thereby effectively reducing or eliminating vibrations when the rotor blades of the vehicle door 1 are opened by passing a minute current through it.
[0085] In the present invention, the buffer block provides a buffering force to the side assembly 2 and the vehicle door component 32, thereby maximizing vibration reduction of the vehicle door 1 during unlocking and movement, and simultaneously passing a small current through the electric door actuator to compensate for the minute gap between the electric door actuator mechanisms, thereby preventing the vehicle door 1 from vibrating.
[0086] Similarly, the method for eliminating vibration when the vehicle door 1 is opened to the side is the same as described above.
[0087] The first locking section 37 is provided with a buffer block and an electrically operated stay through which a small current is passed.
[0088] The buffer block provides a buffering force between the side assembly 2 and the vehicle door component 32, thereby minimizing vibrations during unlocking and movement of the vehicle door 1. At the same time, a small current is passed through the actuator to compensate for minute gaps in the mechanical components, thereby preventing vibrations in the vehicle door 1.
[0089] As shown in Figures 2 and 7, the present invention requires that the second lock body 362 and the electric side-opening door actuator of the second locking section 36 be mounted inside the vehicle door 1, the rotor blade drive mechanism 33 has one end connected to the side assembly 2 and the other end connected to the vehicle door component 32, the first lock catch 371 of the first locking section 37 is connected to the vehicle door component 32 and the first lock body 372 is connected to the side assembly 2, and the side assembly is required to make adaptive clearance relative to the vehicle door component 32 to avoid interference.
[0090] Example 2 The electric system 3 disclosed in the present invention can realize two types of opening methods: electric rotor lift (rotor blade opening) and electric horizontal rotation opening (side opening), and can switch between the two types of modes electrically.
[0091] Realization of an electrically operated rotary-wing door: The control module controls the lock control component 38 to release the first locking part 37 and lock the second locking part 36, preventing relative movement between the vehicle door component 32 and the vehicle door connecting component 34. Furthermore, a three-dimensional spatial link structure is formed between the vehicle door component 32, the vehicle door connecting component 34 and the vehicle body component 31, the link 42, and the rotating rod 41. After the control module supplies current to the electric stay, the extension and retraction of the electric stay is realized, and furthermore, the rotational upward and downward movement of the vehicle door 1 is realized.
[0092] Realization of electric side opening: The control module controls the lock control component 38 to lock the first locking part 37 and release the second locking part 36, allowing relative rotation between the vehicle door component 32 and the vehicle door connecting component 34, so that there is no relative movement between the vehicle door 1 and the vehicle body component 31. In this case, current is supplied to the electric side door actuator, causing the drive arm of the electric side door to extend and retract, and further driving the vehicle door 1 to achieve electric side opening and rotation.
[0093] In the present invention, the locking mechanism includes a first locking part 37, a second locking part 36, a locking control component 38, and a cable 3801.
[0094] When the electric rotary-wing door is opened, the control module controls the motor in the lock control component 38 to rotate in reverse, driving the cable 3801, and further releases the first locking part 37 and locks the second locking part 36, thereby enabling the hinge to switch the structure of the electric rotary-wing door.
[0095] When the electrically operated side opening is released: The controller controls the motor in the lock control component 38 to rotate in the forward direction and drive the cable 3801, and further locks the first locking part 37 and releases the second locking part 36, thereby enabling the hinge to switch between electrically operated side opening and closing structures.
[0096] In the present invention, the electric side-opening actuator is fixed to the vehicle door 1 by the electric side-opening actuator housing, and the drive arm of the electric side-opening actuator is connected to the second extension plate 323 of the vehicle door component 32. Such a design makes it possible to integrate the electric side-opening door and the electric rotary-wing door into a single hinge.
[0097] Switching between the electrically operated rotary-wing door and the electrically operated side-opening door can be done by inputting commands using the following method.
[0098] Self-adaptive switching: The control module recognizes the distance to overhead and ground obstacles using detection radar and decides how to open the doors based on the distance. Voice commands: Switching between electric rotary wing doors and electric side opening is controlled by voice. Hard switches: By installing hard switches on a part of the vehicle, switching between electric rotary wing doors and electric side opening is achieved by directly pressing a button. Triggers such as soft switches: Switching between electric rotary wing doors and electric side opening is controlled by a large screen soft switch.
[0099] When the electric rotary-wing door is in motion: a small current is passed through the electric door actuator, the second locking part 36 is locked, and a buffer block is designed between the vehicle door connecting part 34 and the vehicle door 1 to prevent relative movement between the vehicle door 1 and the vehicle door connecting part 34, and further prevent vibration when the vehicle door 1 rotates upward.
[0100] When the electric side opening mechanism is in operation: A small current is passed through the electric stay, and a buffer block is designed between the vehicle door part 32 and the side assembly 2. Assembly 2 The system prevents shaking between the vehicle door component 32 and the vehicle door 1 when it rotates.
[0101] Clearly, the concrete realization of the present invention is not limited to the above-described forms, and various non-substantial improvements made by adopting the method concept and technical proposal of the present invention all fall within the scope of the claims of the present invention.
