Description

Technical Field

[0004] , ,

[0001] This application relates to the field of vehicle technology, and more specifically, to door devices, connection devices, and vehicles.

Background Art

[0002] Currently, there are two types of common vehicle doors: swing-out (rotating open) vehicle doors and sliding vehicle doors. Due to the special structure of the sliding vehicle door, it is usually only arranged at the rear door position of the vehicle.

[0003] The slide rail of the sliding vehicle door includes an inner slide rail and an outer slide rail. The inner slide rail is arranged at the upper part of the side panel of the vehicle body and in the door sill area, and the outer slide rail is arranged outside the vehicle body. As a result, foreign objects are likely to accumulate on the slide rail of the sliding vehicle door, affecting the appearance of the vehicle, and the opening degree of the vehicle door is restricted by the vehicle shape.

Summary of the Invention

[0004] Embodiments of the present invention provide a door device, a connection device, and a vehicle that solve problems such as foreign objects being likely to accumulate on the slide rail mechanism of a sliding vehicle door, there being significant restrictions on the vehicle shape when using a sliding vehicle door, the sliding vehicle door cannot be used as a front door, and the opening degree of the vehicle door is restricted by the vehicle shape.

[0005] According to a first aspect, a door device including a door body and a connection device is provided. The connection device includes a slide rail mechanism and a transmission mechanism. The slide rail mechanism includes an internal rack, and the transmission mechanism includes a slide portion that engages with the internal rack. The slide rail mechanism is fixed to the door body, and the transmission mechanism is configured to drive the slide portion and drive the door body to move along the slide rail mechanism.

[0006] For example, the transmission mechanism is fixed to the base, and the base is an object fixed around the door body. Also, if the door body is a vehicle door, the base may be a side panel of the vehicle body inside the cab.

[0007] For example, the transmission mechanism may be a mechanical swing arm including a transmission device, which bends and extends based on the transmission device. When the mechanical swing arm is bent, the door body may be driven to move inward toward the vehicle body, completing the action of closing the vehicle door. When the mechanical swing arm is extended, the door body may be driven to move outward toward the vehicle body, completing the action of opening the vehicle door. This causes the door body and the side panel of the vehicle body to no longer be flush, allowing the door body to slide further laterally.

[0008] For example, the transmission mechanism may alternatively be a hydraulic telescopic arm. When the hydraulic telescopic arm is compressed, the door body may be driven to move inward toward the vehicle body, completing the action of closing the vehicle door. When the hydraulic telescopic arm is extended, the door body may be driven to move outward toward the vehicle body, completing the action of opening the vehicle door. This causes the door body and the side panel of the vehicle body to no longer be flush, and the door body can slide further laterally.

[0009] According to the above technical solution, by using a structure in which the slide rail mechanism cooperates with the transmission mechanism, the use of sliding doors is no longer limited by the vehicle shape, and sliding doors can be used for both the front and rear doors of the vehicle. Conversely, the vehicle shape design is not limited by the use of sliding doors. In addition, this increases the lateral (left-right) sliding opening of the door body and effectively limits the longitudinal (front-back) push-pull opening of the door body.

[0010] With respect to the first aspect, in some embodiments of the first aspect, the slide rail mechanism is fixed to the internal cavity of the door body, and the slide rail mechanism further includes a curved slide rail section and a straight slide rail section, the curved slide rail section being connected to the straight slide rail section.

[0011] According to the above technical solution, the slide rail mechanism can be prevented from being exposed to the outside of the door body, and foreign matter can be prevented from accumulating inside the slide rail. Furthermore, since the transmission mechanism can penetrate deep into the cavity of the door body along the curved slide rail section, the internal space occupied by the transmission mechanism is reduced.

[0012] With respect to the first aspect, in some embodiments of the first aspect, the transmission mechanism further includes a front arm and a rear arm.

[0013] The front arm and the rear arm are located in the same plane, and the first end of the front arm is rotatably connected to the first end of the rear arm.

[0014] For example, since the front arm is rotatably connected to the rear arm, the front arm of the transmission mechanism can rotate around a first axis relative to the rear arm and push the door body in a first direction. The first axis is connected to the front arm and the rear arm Mu It is a straight line perpendicular to the plane in which it is located. The first direction is the direction outward of the door, i.e., the direction in which the door is pushed outward. The specific sliding direction of the door body must be determined by referring to both the oscillation direction of the transmission mechanism and the straight shape of the slide rail of the curved slide rail section. Correspondingly, based on the above structure, the door body can also be pulled back along its original sliding trajectory.

[0015] According to the above technical solution, based on the structure of the mechanical arm, the transmission mechanism can push the door body in a first direction, providing the prerequisite for the lateral sliding of the door body.

[0016] With respect to the first aspect, in some embodiments of the first aspect, the door device further includes a drive mechanism, and the transmission mechanism further includes a sixth transmission and a seventh transmission, the seventh transmission being fixed to the second end of the rear arm, the seventh transmission engaging with the sixth transmission, and the sixth transmission being connected to the drive mechanism.

[0017] For example, the drive mechanism may be driven by a motor.

[0018] For example, the sixth transmission unit is a worm gear, the seventh transmission unit is a bevel gear, the worm wheel of the sixth transmission unit engages with the seventh transmission unit, and the worm of the sixth transmission unit is fixed to the drive shaft of the drive mechanism.

[0019] For example, when the drive mechanism is activated, it drives the worm of the sixth transmission unit to rotate around its axis, the worm of the sixth transmission unit to rotate the worm wheel of the sixth transmission unit, the worm wheel of the sixth transmission unit to rotate the seventh transmission unit, and the seventh transmission unit to rotate the rear arm around its axis. This fulfills the prerequisites for transmitting the driving force to the sliding unit.

[0020] For example, to enable the use of the door equipment in non-electric sliding door scenarios, such as unexpected scenarios like the power to the drive mechanism being turned off, a clutch mechanism is further provided between the sixth and seventh transmission units. The clutch mechanism includes both a disengaged state and a connected state. When the drive motor is not operating, the clutch mechanism switches to the disengaged state, disconnecting the connection between the sixth and seventh transmission units, i.e., the engaging force, thereby allowing the door body to be easily pushed and slid manually. When the drive motor is operating, the clutch mechanism switches to the connected state, connecting the sixth transmission unit to the seventh transmission unit, allowing the drive motor to transmit driving force to the transmission mechanism and achieve automatic sliding of the door body.

[0021] The above technical solutions provide the prerequisites for achieving automatic opening and closing of the door itself, thereby improving the convenience of using the vehicle.

[0022] Regarding the first aspect, in some embodiments of the first aspect, the transmission mechanism further includes an eighth transmission part, the eighth transmission part is fixed to the second end of the front arm, and the eighth transmission part is engaged with the sliding part.

[0023] According to the above technical solution, by using the eighth transmission part, the transmission force can ultimately be applied to the sliding part. Further, based on the rotation of the sliding part and the engagement relationship between the sliding part and the slide rail mechanism, the door body is pulled to slide along the linear shape of the slide rail of the slide rail mechanism.

[0024] Regarding the first aspect, in some embodiments of the first aspect, the eighth transmission part includes a first bevel gear and a second bevel gear, the sliding part includes a spur gear, the first bevel gear is coaxially fixed to the second end of the front arm, and the second bevel gear engages with both the first bevel gear and the sliding part.

[0025] According to the above technical solution, the transmission force transmitted to the eighth transmission part is further transmitted to the sliding part, and can provide a prerequisite for the sliding part to drive the door body.

[0026] Regarding the first aspect, in some embodiments of the first aspect, the transmission mechanism further includes a first transmission part, a third transmission part, and a second transmission part, the first transmission part is coaxially fixed to the first end of the rear arm, the third transmission part is coaxially fixed to the first end of the front arm, and the second transmission part engages with both the first transmission part and the third transmission part.

[0027] According to the above technical solution, the front arm of the transmission mechanism can be rotatably connected to the rear arm. In this way, the front arm rotates around the first axis with respect to the rear arm and pushes the door body in the first direction. The first axis is the axis of the rotation mechanism.

[0028] <000OO90>Regarding the first aspect, in some embodiments of the first aspect, the first transmission part and the second transmission part are bevel gears, the third transmission part is a bevel gear with a variable transmission ratio, and the variable transmission ratio coefficient of the third transmission part is greater than 1.

[0029] For example, assume that the variable transmission ratio coefficient of the third transmission part is M. When the second transmission part rotates once, based on the characteristics of the variable transmission ratio of the third transmission part, the transmission ratio from the second transmission part to the third transmission part can be increased by M times. In other words, the third transmission part can rotate M times, and based on the M rotations of the third transmission part, the front arm is driven to rotate M times around its own axis. When there is no gear with a variable transmission ratio between the slide part and the front arm, the slide part can also rotate M times. Through appropriate calculations, after the slide part rotates M times, the slide part can cover the slide rail trajectory of the entire slide rail mechanism.

[0030] According to the above technical solution, the transmission mechanism can realize bending and stretching movements, and the door body can realize opening and closing movements. Furthermore, a prerequisite for finally transmitting the transmission force to the slide part is provided, and the door body can slide horizontally.

[0031] Regarding the first aspect, in some embodiments of the first aspect, the door device further includes a first sleeve, the first sleeve is sleeved on and fixed to the front arm, the first sleeve includes a fifth transmission part, the transmission mechanism further includes a fourth transmission part, the fourth transmission part is an intermittent transmission part and is coaxially fixed to the second transmission part, and the fourth transmission part engages with the fifth transmission part.

[0032] For example, since the fourth transmission part is an intermittent transmission part and the fourth transmission part is coaxial with the second transmission part, after the fourth transmission part engages with the fifth transmission part of the first sleeve, the driving force of the driving mechanism is transmitted to the second transmission part through the components of the transmission mechanism, and when the second transmission part is rotationally driven, the fourth transmission part rotates together with the second transmission part and intermittently rotationally drives the fifth transmission part, thereby causing the first sleeve to swing the front arm within a first range. The first range is an interval range of a first angle, and the first angle is the included angle between the front arm and the rear arm. The size of the first range is related to the structure of the fourth transmission part. For example, in the case of an incomplete gear, the more the number of serrated parts, the wider the first range.

[0033] According to the above technical solution, the front arm can swing intermittently, and after the front arm extends to a specific position, the door body is driven to continue sliding laterally based on the drive mechanism and is not pushed outward any further. Furthermore, since the first sleeve is used to enclose the front arm, the front arm is protected and prevented from becoming entangled with other parts as it rotates around its own axis.

[0034] With respect to the first aspect, in some embodiments of the first aspect, the fourth transmission unit is one of an incomplete gear, a grooved wheel, a ratchet, or a cam.

[0035] For example, in order to achieve the engagement relationship between the fourth and fifth transmission units, the specific configuration of the fifth transmission unit must match the specific configuration of the fourth transmission unit. For instance, if the fourth transmission unit is an incomplete gear, the fifth transmission unit is a rack.

[0036] For example, if the fourth transmission is an incomplete gear, after the fourth transmission rotates by a first angle, it continues to rotate based on the rotation of the second transmission, but the part of the fourth transmission that does not have a sawtooth does not engage with the fifth transmission. Therefore, even if the fourth transmission rotates continuously, the swing arm based on the fourth transmission does not oscillate continuously. Also, since the sliding part that rotates based on the transmitted force also rotates continuously, a motion relationship is achieved in which the transmission mechanism oscillates intermittently and the sliding part can rotate continuously.

[0037] According to the above technical solution, the front arm can swing intermittently, and once the front arm extends to a specific position, it is driven by the drive mechanism to continue sliding laterally, but is not pushed out any further.

[0038] With respect to the first aspect, in some embodiments of the first aspect, the door device further includes a second sleeve, the second sleeve being sleeve-mounted to and fixed to the rear arm, and the second sleeve being fixed to the front arm.

[0039] For example, the door equipment further includes a fixing part, which is configured to fix a second sleeve to a base part and a transmission mechanism to the base part. The base part is an object fixed around the door body. Alternatively, if the door body is a vehicle door, the base part may be a side panel of the vehicle body inside the cab.

[0040] According to the above technical solution, the front arm of the transmission mechanism can swing intermittently, thereby pushing the door body outward. This sets the prerequisites for the door body to slide laterally and ensures that the second opening angle is maintained within a narrow range. Furthermore, since the sleeve is used to enclose the outside of the transmission mechanism, the transmission mechanism is protected and can be prevented from becoming entangled with or colliding with other parts, thereby improving the safety of the door equipment.

[0041] According to a second embodiment, a connecting device is provided. The connecting device includes a slide rail mechanism and a transmission mechanism, the slide rail mechanism including an internal rack, and the transmission mechanism including a sliding part, the sliding part engaging with the internal rack. The slide rail mechanism is configured to move relative to the sliding part by the driving of the sliding part.

[0042] For example, the connecting device can be used for purposes other than the door itself. In other words, the object to which it is attached is not limited to the door itself. The connecting device allows the object to which it is attached to slide along the straight shape of the slide rail of the slide rail mechanism.

[0043] With respect to a second aspect, in some embodiments of the second aspect, the slide rail mechanism further includes a curved slide rail section and a straight slide rail section, the curved slide rail section being connected to the straight slide rail section.

[0044] With respect to the second aspect, in some embodiments of the second aspect, the transmission mechanism further includes a front arm and a rear arm.

[0045] The front arm and the rear arm are located in the same plane, and the first end of the front arm is rotatably connected to the first end of the rear arm.

[0047] With respect to a second aspect, in some embodiments of the second aspect, the transmission mechanism further includes an eighth transmission unit, the eighth transmission unit being fixed to the second end of the front arm, and the eighth transmission unit engaging with the sliding unit.

[0048] With respect to a second aspect, in some embodiments of the second aspect, the eighth transmission section includes a first bevel gear and a second bevel gear, the sliding section includes a spur gear, the first bevel gear is coaxially fixed to the second end of the front arm, and the second bevel gear engages with both the first bevel gear and the sliding section.

[0050] With respect to the second aspect, in some embodiments of the second aspect, the first and second transmission units are bevel gears, and the third transmission unit is a bevel gear having a variable transmission ratio, wherein the variable transmission ratio coefficient of the third transmission unit is greater than 1.

[0051] With respect to a second aspect, in some embodiments of the second aspect, the connecting device further includes a first sleeve, which is sleeve-mounted to and fixed to a front arm, and the first sleeve includes a fifth transmission unit, and the transmission mechanism further includes a fourth transmission unit, which is an intermittent transmission unit and is fixed coaxially to the second transmission unit, and the fourth transmission unit engages with the fifth transmission unit.

[0052] With respect to the second aspect, in some embodiments of the second aspect, the fourth transmission is one of an incomplete gear, a grooved wheel, a ratchet, or a cam.

[0053] With respect to a second aspect, in some embodiments of the second aspect, the connecting device further includes a second sleeve, which is sleeve-mounted to and fixed to the rear arm, and the second sleeve is fixed to the front arm.

[0054] According to a third aspect, a door device is provided for use on a vehicle, comprising a door body and a double four-link. The double four-link includes a first fastening portion, a second fastening portion, a third fastening portion, and a fourth fastening portion. The first and second fastening portions are fixed to the edge of a side panel of the vehicle body, and the third and fourth fastening portions are fixed to the door body.

[0055] According to the above technical solution, since the door body is pushed in and pulled in using a double four-link mechanism, there is no risk of foreign objects accumulating on the slide rail. , a Main unit 400 Doors using device This system is no longer limited by the vehicle's shape and can be used on both the front and rear doors of a vehicle.

[0057] For example, the drive mechanism applies driving force to the transmission mechanism, and the transmission mechanism automatically opens and closes the vehicle door by deploying or compressing a double four-link based on the driving force.

[0058] The above technical solutions can enable automatic opening and closing of the door itself, improving the user experience and comfort of the vehicle.

[0059] According to a fourth aspect, a vehicle is provided which includes a door device as described in any one of the possible embodiments of the third aspect.

[0072] The door equipment provided in this application may be used in a mobile transport vehicle. A mobile transport vehicle in this application may include road transport, water transport, air transport, industrial equipment, agricultural equipment, or entertainment equipment. For example, a mobile transport vehicle may be a vehicle. Vehicles are in a broad sense and can include transport means (e.g., commercial vehicles, passenger cars, motorcycles, airplanes, or trains), industrial vehicles (e.g., pallet trucks, trailers, or tractors), construction vehicles (e.g., excavators, bulldozers, or cranes), agricultural equipment (e.g., lawnmowers or harvesters), entertainment equipment, or toy vehicles. In the embodiments of this application, the type of vehicle is not particularly limited. As another example, a mobile transport vehicle may be a transport means such as an airplane or ship.

[0073] In some possible embodiments, the door devices provided herein can also be used for other objects, such as buildings, including houses or enclosed booths.

[0074] Let's take a typical vehicle as an example. Currently, there are two types of typical vehicle doors: swing-out type and sliding type. Figure 1 is a diagram of a sliding type vehicle door. Please refer to Figure 1. It can be seen that the sliding rail of a sliding type vehicle door includes an inner sliding rail 10 and an outer sliding rail 11, with the inner sliding rail 10 located on the upper part of the side panel 600 of the vehicle body and in the door sill area, and the outer sliding rail 11 located on the outside of the vehicle body. However, before The short lateral (L-direction) length of the door sill of the vehicle body at door 01 affects the shape design of the vehicle body. For example, the small curvature between the B-pillar and C-pillar of the side panel 600 of the vehicle body and the resulting large shape constraints mean that in the multi-purpose vehicle (MPV) shown in Figure 1, sliding vehicle doors are usually used, and only the rear door 02 can be made to slide, and it cannot be used for the front door 01. Also, the first opening angle X for sideways opening is small, and the second opening angle Y for outward opening is large. For example, several common MPIn design V, the first opening angle X for sideways opening of the sliding vehicle door is typically less than 700 mm, and the second opening angle Y for outward opening is typically greater than 250 mm. Furthermore, foreign objects tend to accumulate on the outer sliding rail 11 and the inner sliding rail 10.

[0075] With this in mind, embodiments of the present invention provide a door device. A slide rail mechanism 210 and a transmission mechanism 220 fixed to the side of the vehicle body are used to replace the design of the combination of an inner slide rail 10 and an outer slide rail 11 of a sliding vehicle door, thereby realizing outward opening and lateral sliding operation of the sliding door. This helps to increase the first opening angle X for lateral opening of the sliding door and decrease the second opening angle Y for outward opening. Furthermore, this door device is applicable to front and rear doors of a vehicle and is not limited to the shape design of the vehicle.

[0076] In some possible embodiments, the door equipment provided in the embodiments of the present application may be used in a vehicle or in other scenarios, such as a house or building.

[0077] Figure 2 shows a door device 200 according to one embodiment of the present invention.

[0078] In some possible embodiments, the door equipment 200 includes a door body 400, a slide rail mechanism 210, and a transmission mechanism 220. The slide rail mechanism 210 includes an internal rack 211, the transmission mechanism 220 includes a slide portion 2210 which engages with the internal rack 211, the slide rail mechanism 210 is fixed to the door body 400, and the transmission mechanism 220 is configured to drive the slide portion 2210 and the door body 400 to move along the slide rail mechanism 210.

[0079] In some possible embodiments, the slide rail mechanism 210 is fixed to the internal cavity of the door body 400. This structure prevents the slide rail mechanism 210 from being exposed to the outside of the door body 400 and prevents foreign matter from accumulating inside the slide rail.

[0080] In some possible embodiments, the transmission mechanism 220 is fixed to a base portion 500, which is an object fixed around the door body 400. Furthermore, if the door body 400 is a vehicle door, the base portion 500 may be a side panel 600 of the vehicle body inside the cab.

[0081] Referring to Figure 2, in some possible embodiments, the transmission mechanism 220 may be a mechanical swing arm including a transmission device, which bends and extends based on the transmission device. When the mechanical swing arm is bent, the door body 400 is driven to move toward the inside of the vehicle body, completing the closing operation of the vehicle door. When the mechanical swing arm is extended, the door body 400 may be driven to move toward the outside of the vehicle body, completing the opening operation of the vehicle door, so that the door body 400 and the side panel 600 of the vehicle body are not in the same plane, and the door body 400 can slide further laterally.

[0082] Figure 3 shows another door device 200 according to one embodiment of the present invention.

[0083] In some possible embodiments, the transmission mechanism 220 further includes a front arm 2211 and a rear arm 2212. The front arm 2211 and the rear arm 2212 are located in the same plane, and the first end of the front arm 2211 is rotatably connected to the first end of the rear arm 2212.

[0084] According to the above technical solution, since the front arm 2211 is rotatably connected to the rear arm 2212, the front arm 2211 of the transmission mechanism 220 can rotate around a first axis relative to the rear arm 2212. The first axis is connected to the front arm 2211 and the rear arm 221 2 This is a straight line perpendicular to the plane in which the door is located, and it pushes the door body 400 in the first direction A. The first direction A is the direction outward of the door, that is, the direction in which the door is pushed outward.

[0085] In some possible embodiments, the door device 200 can satisfy the functional requirements of an electrically operated sliding door. The oscillating motion of the transmission mechanism 220 can be realized based on a drive mechanism. The drive mechanism may be driven based on a motor, and the transmission mechanism 220 transmits the driving force of the motor to the sliding part 2210 based on the engagement relationship between the sliding part 2210 and the internal rack 211, and the sliding part 2210 pulls the entire door body 400, based on the engagement relationship with the internal rack 211 of the slide rail mechanism 210, causing it to slide along the linear shape of the slide rail of the slide rail mechanism 210, thereby causing the lateral opening of the door body 400 to reach a first opening X. The first opening X is equal to the linear length mapped to the lateral L of the slide rail mechanism 210. This design provides conditions for maximizing the first opening X, and the door body 400 but Fully open When the first opening degree X is It can be made larger than 700mm.

[0086] Refer to the door equipment 200 shown in Figure 3. When the slide rail mechanism 210 consists only of a straight slide rail section 213, the arm span of the mechanical swing arm used as the transmission mechanism 220 is considered to need to be long enough to push the door body 400 to a position that is not flush with the side panel 600 of the vehicle body. In such a structural design, the front arm 2211 of the mechanical arm is long, occupying a large space inside the vehicle body, which may increase the second opening degree Y of the outward opening of the door body 400, and occupying a large space outside the vehicle body. Furthermore, after the door body 400 is completely closed, a large gap exists between the door body 400 and the side panel 600 of the vehicle body.

[0087] Based on this, one embodiment of the present invention provides another door device 200 to solve the above problem.

[0088] Figure 4 shows another door device 200 according to one embodiment of the present invention.

[0089] In some possible embodiments, the slide rail mechanism 210 includes a curved slide rail section 212 and a straight slide rail section 213, the curved slide rail section 212 being connected to the straight slide rail section 213.

[0090] Refer to the door equipment 200 shown in Figure 4. Because the front arm 2211 of the transmission mechanism 220 can enter deep into the cavity of the door body 400 along the curved slide rail section 212, the arm span of the front arm 2211 is significantly shorter than the arm span of the front arm 2211 shown in Figure 3, and it can be seen that the internal space occupied by the vehicle body is reduced. This allows the second opening angle Y to be kept small and controlled to within 250 mm. In other words, when the door body 400 is fully open, the external space occupied by the vehicle body is reduced, and when the door body 400 is fully closed, a small gap is created between the door body 400 and the side panel 600 of the vehicle body.

[0091] Figure 5 shows another door device 200 according to one embodiment of the present invention.

[0092] In some possible embodiments, the transmission mechanism 220 may instead be a hydraulically telescopic arm. When the hydraulically telescopic arm is compressed, the door body 400 may be driven to move inward toward the vehicle body, completing the operation of closing the vehicle door. When the hydraulically telescopic arm is extended, the door body 400 may be driven to move outward toward the vehicle body, completing the operation of opening the vehicle door. This causes the door body 400 and the side panel 600 of the vehicle body to no longer be in the same plane, and the door body 400 may slide further laterally.

[0093] In some possible embodiments, a transmission mechanism 220 in the form of a hydraulically telescopic arm can also cooperate with a drive mechanism 230 to form an electrically operated sliding door with the door body 400, thereby meeting the functional requirements of an electrically operated sliding door. The drive mechanism 230 may be driven on a motor. Based on a movable connection between the transmission mechanism 220 and the slide rail mechanism 210, the transmission mechanism 220 drives the entire door body 400 via the slide rail mechanism 210 to slide along the linear shape of the slide rail of the slide rail mechanism 210. The first opening X of the lateral slide of the door body 400 is equal to the linear length mapped to the lateral L of the slide rail mechanism 210. This design provides conditions for maximizing the first opening X, allowing the door body 400 to be more than 700 mm in the fully open position.

[0094] In some possible embodiments, similar to the door equipment 200 shown in Figure 3, the door equipment 200 shown in Figure 5 also faces a similar problem when the slide rail mechanism 210 is a straight guide rail. The hydraulic telescopic arm requires a sufficient arm span length to push the door body 400 to a position where it is not flush with the side panel 600 of the vehicle body. In such a structural design, it is assumed that the hydraulic telescopic arm consists of N sections, with the first section being the side fixed to the side panel 600 of the vehicle body. In this case, the length of the first section must be controlled to ensure that the door body 400 and the side panel 600 of the vehicle body are flush when the door body 400 is fully closed. Furthermore, the arm span of the hydraulic telescopic arm must be sufficiently long. See Figure 5. The following condition must be met: H1 + H2 <= H3. In this case, N must be sufficiently large, increasing cost and the difficulty of process manufacturing.

[0095] Based on this, one embodiment of the present invention provides another door device 200 to solve the above problem.

[0096] Figure 6 shows another door device 200 according to one embodiment of the present invention.

[0097] In some possible embodiments, the slide rail mechanism 210 includes a curved slide rail section 212 and a straight slide rail section 213, the curved slide rail section 212 being connected to the straight slide rail section 213.

[0098] Refer to the door equipment 200 shown in Figure 6. The hydraulic telescopic arm used as the transmission mechanism 220 can enter deep into the cavity of the door body 400 along the curved slide rail section 212, so the arm span of the hydraulic telescopic arm is significantly shorter compared to the arm span of the hydraulic telescopic arm shown in Figure 5, and it can be seen that it occupies less of the internal space of the vehicle body. This helps to keep the second opening angle Y small and can be controlled to within 250 mm. In this way, the door body 400 occupies less of the external space of the vehicle body when fully open, and after the door body 400 is completely closed, a small gap is created between the door body 400 and the side panel 600 of the vehicle body.

[0099] In some possible embodiments, the door device 200 based on the above design is such that the sliding door is no longer limited by the shape of the vehicle, and the sliding door can be used as either the rear door or the front door of the vehicle.

[0100] According to the above technical solution, since the slide rail mechanism 210 is hidden within the door body 400, foreign matter is less likely to accumulate on the slide rail mechanism 210. Furthermore, because the slide rail mechanism 210 employs a structure in which it cooperates with the transmission mechanism 220, the sliding door is no longer limited by the shape of the vehicle, and the sliding door can be used for both the front and rear doors of the vehicle. Also Furthermore, the use of sliding doors does not restrict the design of the vehicle's shape. In addition, with sliding doors using door equipment 200, the second opening angle Y for outward opening is small, and the first opening angle X for sideways opening is large, which improves the practicality and comfort of the vehicle.

[0101] In the following, we will describe in detail the configuration in which the transmission mechanism 220 is the aforementioned mechanical swing arm, and the slide rail mechanism 210 includes a curved slide rail section 212 and a straight slide rail section 213.

[0102] Figure 7 shows a transmission mechanism 220 according to one embodiment of the present invention.

[0103] In some possible embodiments, when the door device 200 is used in an electric sliding door scenario, the door device further includes a drive mechanism 230, and the transmission mechanism 220 further includes a sixth transmission 226 and a seventh transmission 227, the seventh transmission 227 being fixed to the second end of the rear arm 2212, the seventh transmission 227 engaging with the sixth transmission 226, and the sixth transmission 226 being connected to the drive mechanism 230.

[0104] In some possible embodiments, the sixth transmission unit 226 is a worm gear, the seventh transmission unit 227 is a bevel gear, the worm wheel 2261 of the sixth transmission unit 226 engages with the seventh transmission unit 227, and the worm 2262 of the sixth transmission unit 226 is fixed to the drive shaft of the drive mechanism 230.

[0105] In some possible embodiments, when the drive mechanism 230 is actuated, it rotates the worm 2262 of the sixth transmission unit 226 around its own axis, the worm 2262 of the sixth transmission unit 226 rotates the worm wheel 2261 of the sixth transmission unit 226, the worm wheel 2261 of the sixth transmission unit 226 rotates the seventh transmission unit 227, and the seventh transmission unit 227 rotates the rear arm 2212 around its own axis. This is a prerequisite for transmitting the driving force to the slide unit 2210.

[0106] The above technical solutions are prerequisites for achieving automatic opening and closing of the door body 400, thereby improving the convenience of using the vehicle.

[0107] In some possible embodiments, a clutch mechanism is further provided between the worm wheel and the worm of the sixth transmission unit 226 to enable the door device 200 to be used in non-electric sliding door scenarios, such as unexpected scenarios including the power off of the drive mechanism 230. The clutch mechanism includes a disengaged state and a connected state. When the drive motor is not operating, the clutch mechanism switches to the disengaged state, disconnecting the connection between the worm wheel 2261 and the worm 2262 of the sixth transmission unit 226, thereby allowing the door body 400 to be easily pushed and slid manually. When the drive motor is operating, the clutch mechanism switches to the connected state, connecting the worm wheel 2261 to the worm 2262 of the sixth transmission unit 226, thereby allowing the drive motor to transmit driving force to the transmission mechanism 220, enabling the automatic sliding of the door body 400.

[0108] Figure 8 shows a clutch mechanism 260 according to one embodiment of the present invention. Here, Figure 8(a) is a front view of the clutch mechanism 260, and Figure 8(b) is a top view of the clutch mechanism 260.

[0109] Refer to Figure 8. The front of the drive mechanism 230 is fixed to the threaded rod of the sixth transmission unit 226, and it can be seen that the clutch mechanism 260 includes a pin portion 261 and a movable portion 262. The pin portion 261 is wedge-shaped, and the wedge surface of the pin portion 261 contacts the first side surface of the drive mechanism 230 (which may be the left side surface of the drive mechanism 230 in the front view), and the surface of the pin portion 261 opposite to the wedge surface contacts the surrounding base portion 500, which may be a wedge surface or a flat surface. The first end of the movable portion 262 is connected to the second side surface of the drive mechanism 230 (which may be the right side surface of the drive mechanism 230 in the front view), and the second end of the movable portion 262 is connected to the surrounding base portion 500.

[0110] In some possible embodiments, the drive mechanism 230 may further include a mounting portion 231 to avoid excessive wear of the drive mechanism 230 during the insertion or removal of the pin portion 261, and the wedge surface of the pin portion 261 may be in contact with the mounting portion 231.

[0111] In some possible embodiments, the movable part 262 may be a spring structure.

[0112] In some possible embodiments, referring to Figure 8(b), the drive mechanism 230 is connected to the worm 2262 of the sixth transmission unit. If the movable part 262 is a spring structure, after inserting the pin portion 261 between the base portion 500 and the drive mechanism 230, the drive mechanism 230 compresses the movable part 262, thereby moving the worm 2262 to the right with the drive mechanism 230 until the worm 2262 is connected to the worm wheel 2261. When the pin portion 261 is withdrawn between the base portion 500 and the drive mechanism 230, the movable part 262 pushes the drive mechanism 230 to the left, thereby moving the worm 2262 to the left with the drive mechanism 230 until the worm 2262 is separated from the worm wheel 2261.

[0113] The above technical solution enables the switching clutch state function of the sixth transmission unit 226. In the event of an unexpected situation such as the power to the drive mechanism 230 being turned off, the clutch mechanism 260 disconnects the connection between the worm wheel 2261 and the worm 2262 of the sixth transmission unit 226, thereby allowing the door body 400 to be easily pushed and slid manually.

[0114] In some possible embodiments, the transmission mechanism 220 further includes an eighth transmission unit 228, which is fixed to the second end of the front arm 2211 and engages with the sliding unit 2210.

[0115] In some possible embodiments, the eighth transmission section 228 includes a first bevel gear 2281 and a second bevel gear 2282, and the sliding section 2210 includes a spur gear, the first bevel gear 2281 being coaxially fixed to the second end of the front arm 2211, and the second bevel gear 2282 engaging with both the first bevel gear 2281 and the sliding section 2210.

[0116] According to the above technical solution, the transmission force can ultimately be applied to the sliding part by using the eighth transmission part 228. Furthermore, based on the rotation of the sliding part 2210 and the engagement relationship between the sliding part 2210 and the slide rail mechanism 210, the door body 400 is pulled to slide along the linear shape of the slide rail of the slide rail mechanism 210.

[0117] In some possible embodiments, the transmission mechanism 220 further includes a first transmission section 221, a second transmission section 222, and a third transmission section 223. The first transmission section 221 is coaxially fixed to the rear arm 2212, the third transmission section 223 is coaxially fixed to the first end of the front arm 2211, and the second transmission section 222 engages with both the first transmission section 221 and the third transmission section 223.

[0118] In some possible embodiments, the second transmission unit 222 may engage with both the first transmission unit 221 and the third transmission unit 223 via a gear. The The first transmission unit 221 and the second transmission unit 222 may be bevel gears, and the third transmission unit may be a bevel gear having a variable transmission ratio, wherein the variable transmission ratio coefficient of the third transmission unit is greater than 1.

[0119] By using the device structure provided in the above-described embodiment, the front arm 2211 of the transmission mechanism 220 can be rotatably connected to the rear arm 2212. In this way, the front arm 2211 rotates around a first axis relative to the rear arm 2212, pushing the door body 400 in the first direction A. The first axis is the axis of the rotation mechanism. For example, the door body 400 is a vehicle door, and the first direction A is the direction in which the vehicle door is pushed outward.

[0120] In some possible embodiments, as the rear arm 2212 rotates around its own axis, the rear arm 2212 rotates the first transmission unit 221, the first transmission unit 221 rotates the second transmission unit 222, the second transmission unit 222 rotates the third transmission unit 223, and the third transmission unit 223 rotates the front arm 2211 around its own axis. This is a prerequisite for ultimately transmitting the force to the sliding unit 2210.

[0121] In some possible embodiments, assume that the variable transmission ratio coefficient of the third transmission unit 223 is M. When the second transmission unit 222 rotates once, the transmission ratio from the second transmission unit 222 to the third transmission unit 223 can increase by M times, based on the variable transmission ratio characteristics of the third transmission unit 223. In other words, the third transmission unit 223 can rotate M times, and based on the M rotation of the third transmission unit 223, the front arm 2211 is driven to rotate M times around its own axis. If there is no gear with a variable transmission ratio between the slide unit 2210 and the front arm 2211, the slide unit 2210 can also rotate M times. With appropriate calculations, after the slide unit 2210 has rotated M times, the slide unit 2210 can cover the entire slide rail trajectory of the slide rail mechanism 210.

[0122] According to the above technical solution, the transmission mechanism 220 can perform bending and extending movements, thereby enabling the door body 400 to perform opening and closing movements. Furthermore, prerequisites are provided for finally transmitting the transmission force to the sliding part 2210, allowing the door body 400 to slide in the left-right direction.

[0123] Figure 9 shows another door device 200 according to one embodiment of the present application.

[0124] In some possible embodiments, the door device further includes a first sleeve 240 which is sleeve-mounted to and fixed to the front arm 2211, and the first sleeve 240 includes a fifth transmission unit 245, and the transmission mechanism 220 further includes a fourth transmission unit 224 which is an intermittent transmission unit and is fixed coaxially to the second transmission unit 222, and the fourth transmission unit 224 engages with the fifth transmission unit 245.

[0125] In some possible embodiments, the fourth transmission unit 224 may be one of the following components: an incomplete gear, a grooved wheel, a ratchet, or a cam.

[0126] In some possible embodiments, the specific configuration of the fifth transmission unit 245 must match the specific configuration of the fourth transmission unit 224 in order to achieve the engagement relationship between the fourth transmission unit 224 and the fifth transmission unit 245. For example, if the fourth transmission unit 224 is an incomplete gear, the fifth transmission unit 245 is a rack.

[0127] According to the above technical solution, the front arm 2211 can swing intermittently, and after the front arm 2211 extends to a certain position, the door body 400 is driven only to continue sliding laterally based on the drive mechanism 230, ensuring that it is not pushed out any further. Furthermore, since the first sleeve 240 is used to enclose the front arm 2211, the front arm 2211 is protected, and this protects the front arm 2211 from becoming entangled with other parts in the process of rotating around its own axis.

[0128] Figure 10 is a side view of a transmission mechanism 220 according to one embodiment of the present invention.

[0129] In some possible embodiments, the fourth transmission unit 224 is an intermittent transmission unit, and since the fourth transmission unit 224 is coaxial with the second transmission unit 222, after the fourth transmission unit 224 engages with the fifth transmission unit 245 of the first sleeve 240, the driving force of the drive mechanism 230 is transmitted to the second transmission unit 222 via the components of the transmission mechanism 220, causing the second transmission unit 222 to rotate. As a result, the fourth transmission unit 224 rotates together with the second transmission unit 222, intermittently rotating the fifth transmission unit 245, thereby driving the first sleeve 240 to swing the front arm 2211 within a first range. The first range is a range of intervals of a first angle α, where the first angle α is the angle between the front arm 2211 and the rear arm 2212. The size of the first range is related to the structure of the fourth transmission unit 224. For example, in the case of an imperfect gear, the more sawtoothed teeth there are, the larger the first range. For example, if the sawtooth portion occupies 1 / 4 of the entire gear, the first range will be an interval of [90°, 180°], which allows the vehicle door to be opened normally without damaging the side panel. For example, if the fourth transmission unit 224 is an incomplete gear, after the fourth transmission unit 224 rotates by a first angle α, the fourth transmission unit 224 continues to rotate based on the rotation of the second transmission unit 222, but the portion of the fourth transmission unit 224 that does not have sawtooth cannot form an engagement relationship with the fifth transmission unit 245. Therefore, even if the fourth transmission unit 224 rotates continuously, the swing arm based on the fourth transmission unit 224 does not swing continuously. Also, since the slide unit 2210 that rotates based on the transmitted force also rotates continuously, a motion relationship is realized in which the transmission mechanism 220 swings intermittently and the slide unit 2210 rotates continuously.

[0130] Referring to Figure 9 or Figure 10, in some possible embodiments, the door device 200 further includes a second sleeve 250 which is sleeve-mounted to and fixed to the rear arm 2212, and the second sleeve 250 is fixed to the front arm 2211.

[0131] In some possible embodiments, the door device 200 further includes a fastening portion 251 configured to secure a second sleeve 250 to a base portion 500 and a transmission mechanism 220 to the base portion 500.

[0132] According to the above technical solution, the front arm 2211 of the transmission mechanism 220 can swing intermittently, thereby pushing the door body 400 outward. This sets the prerequisites for the door body 400 to slide laterally and ensures that the second opening Y is maintained within a narrow range. Furthermore, the sleeve is used to enclose the outside of the transmission mechanism 220, thereby protecting the transmission mechanism 220 and preventing it from becoming entangled with or colliding with other parts, thereby improving the safety of the door device 200.

[0133] One embodiment of the present invention further provides a connecting device. The connecting device includes an optional slide rail mechanism 210 and an optional transmission mechanism 220 provided in the above-described embodiment. Since the connection relationships and operating principles of the components of the slide rail mechanism 210 and transmission mechanism 220 of the connecting device are the same as those of the components of the slide rail mechanism 210 and transmission mechanism 220 of the door device 200, related extensions of the connecting device can be found in the embodiment corresponding to the door device 200, which will not be described again here in detail.

[0134] In some possible embodiments, the connecting device can be used for applications other than the door body 400. In other words, the object to be mounted is not limited to the door body 400. The connecting device allows the object to be mounted to slide along the linear shape of the slide rail of the slide rail mechanism 210.

[0135] One embodiment of the present invention further provides a vehicle door for use in a vehicle. The vehicle door includes at least two connecting devices provided in the above-described embodiment.

[0136] Figure 11 is an exploded view of a door device 200 according to one embodiment of the present invention.

[0137] Please refer to Figure 11. Two connecting devices, for example, the first connecting device 201 and the second connecting device 202, are connected to the aforementioned door body. (car When positioned on both doors, the fixed positions of the first connecting device 201 and the second connecting device 202 are offset from each other. Furthermore, the first connecting device 201 is positioned at a first position on the vehicle door, and the second connecting device 202 is positioned at a second position on the vehicle door. The first and second positions are as far apart as possible in the longitudinal direction of the vehicle door and offset from each other in the lateral direction L of the vehicle door.

[0138] In some possible embodiments, each of the planes on which the slide rail mechanisms 210 of at least two connecting devices are located is parallel to the plane in the lateral direction L of the vehicle door, i.e., the plane in the longitudinal direction of the vehicle door.

[0139] According to the above technical solution, during the lateral sliding process of the door body 400, the door body 400 becomes as parallel as possible to the plane on which the vehicle body side panel 600 is located, preventing damage to the vehicle body side panel 600 and improving the support stability of the door body 400.

[0140] Figure 12 shows the operating principle of a door device 200 according to one embodiment of the present invention.

[0141] For the sake of clarity, only the operation process of one of the door devices 200 will be described below.

[0142] When the door body 400 is in the closed position, the transmission mechanism 220 is in a bent position, and the sliding portion 2210 of the transmission mechanism 220 is located at the tip of the curved sliding rail portion 212 of the sliding rail mechanism 210. In this case, the door body 400 is embedded in the structure of the vehicle body's side panel 600.

[0143] During the process of opening the door body 400, the drive unit starts operating, driving the rotation mechanism of the transmission mechanism 220, thereby causing the transmission mechanism 220 to gradually extend. Specifically, the front arm 2211 of the transmission mechanism 220 begins to swing intermittently. The slide part 2210 also operates synchronously based on the transmitted driving force, and finally applies force to the curved slide rail part 212 of the slide rail mechanism 210, thereby causing the door body 400 to slide laterally and be pushed outward until the door body is no longer flush with the side panel 600 of the vehicle body. In this case, the slide part 2210 moves to a part of the straight slide rail part 213 of the slide rail mechanism 210, and the transmission mechanism 220 completes its intermittent swinging motion due to the action of the fourth transmission part 224 and does not extend any further. Subsequently, the sliding part 2210 continues to operate, applying force to the slide rail mechanism 210, causing the entire door body 400 to slide laterally until the sliding part 2210 reaches the lowest point of the straight slide rail section 213 of the slide rail mechanism 210. In other words, the movement trajectory of the sliding part 2210 covers the straight rail shape of the entire slide rail mechanism 210. In this case, the door body 400 is fully open.

[0144] Let's take an automobile as an example. When the door body 400 is fully open, the first opening angle X of the door body 400 may be greater than 700 mm, and the second opening angle Y of the door body 400 may be limited to within 250 mm. For different vehicle shapes and different vehicle door shapes, the assumed first opening angle X and assumed second opening angle Y will be adjusted accordingly. However, it is possible to provide a basis for maximizing the first opening angle X and minimizing the second opening angle Y while keeping the vehicle shape constant.

[0145] Figure 13 is a diagram showing the communication relationships between the components of a door device 200 according to one embodiment of the present invention.

[0146] Based on the specific configuration of the components described above, the operating principle of the door device 200 can be explained as follows. The motor rotates the worm 2262 of the sixth transmission unit 226 around its own axis, the worm 2262 of the sixth transmission unit 226 rotates the worm wheel 2261 of the sixth transmission unit 226, the worm wheel 2261 of the sixth transmission unit 226 rotates the seventh transmission unit 227, the seventh transmission unit 227 rotates the rear arm 2212 around its own axis, the rear arm 2212 rotates the first transmission unit 221, the first transmission unit 221 rotates the second transmission unit 222, the second transmission unit 222 rotates the third transmission unit 223, the third transmission unit 223 rotates the front arm 2211 around its own axis, the front arm 2211 rotates the eighth transmission unit 228, and the eighth transmission unit 228 drives the slide part 2210 to slide on the slide rail mechanism 210.

[0147] As the sliding portion 2210 slides along the slide rail mechanism 210, the fourth transmission portion 224 rotates together with the second transmission portion 222, intermittently rotating the fifth transmission portion 245, thereby driving the first sleeve 240 to intermittently swing the front arm 2211, and the door body 400 moves along a first trajectory under the constraint of the sliding portion 2210 and the slide rail mechanism 210. The first trajectory conforms to the shape of the curved slide rail portion 212.

[0148] In some possible embodiments, in addition to bevel gear groups or worm gears, other gear combinations may also be applied to the door equipment 200 to enable the sliding of the door body 400 as a transmission method between the aforementioned transmission units. The gear group combination may be multi-stage gear engagement or belt pulley interlocking, and is applicable to the implementation of the aforementioned technical solutions as long as the motor driving force is transmitted to the sliding unit 2210.

[0149] One embodiment of the present invention further provides a vehicle including any of the door devices 200 provided in the above-described embodiments.

[0150] This VowIn some possible embodiments, ,another Door equipment 300 but offer So Door device 300 is a good replacement for the aforementioned door device 200 and can be used in a variety of scenarios.

[0151] Figure 14 shows a door device 300 according to one embodiment of the present invention. Please refer to Figure 14. It can be seen that the door device 300 can be used in a vehicle.

[0152] The door equipment 300 includes a door body 400 and a double four-link 310. The double four-link 310 includes a first fastening portion 311, a second fastening portion 312, a third fastening portion 313, and a fourth fastening portion 314. The first fastening portion 311 and the second fastening portion 312 are fixed to the edge of the side panel 600 of the vehicle body, and the third fastening portion 313 and the fourth fastening portion 314 are fixed to the door body 400.

[0153] According to the above technical solution, the problem of foreign objects easily accumulating on the slide rail is eliminated because the door body 400 is pushed in and pulled in using the double four-link 310. , a Main unit 400 Doors using device teeth, no longer Vehicle shape Control It is not limited to and can be used on both the front and rear doors of a vehicle. Conversely, the vehicle's shape design is not restricted by the use of door equipment.

[0154] In some possible embodiments, the door device 300 further includes a drive mechanism 230, and the double four-link 310 further includes a transmission mechanism 220. The transmission mechanism 220 is connected to the drive mechanism 230. The drive mechanism 230 applies a driving force to the transmission mechanism 220, and the transmission mechanism 220 automatically opens and closes the vehicle door by deploying or compressing the double four-link 310 based on the driving force.

[0155] The above technical solution enables the automatic opening and closing of the door body 400, improving the user experience and comfort of the vehicle.

[0156] Figure 15 shows the operating principle of a door device 300 according to one embodiment of the present invention.

[0157] When the door body 400 is in the closed position, the double four-link 310 is in the bent position.

[0158] During the process of opening the door body 400, the drive mechanism 230 starts operating and applies driving force to the transmission mechanism 220. Based on the driving force, the transmission mechanism 220 deploys a double four-link and pushes the door body 400 diagonally outward until the door body 400 is fully open.

[0159] Let's take an automobile as an example. When the door body 400 is fully open, the first opening angle X of the door body 400 may be greater than 600 mm, and the second opening angle Y of the door body 400 may be limited to within 350 mm. The assumed first opening angle X and assumed second opening angle Y are adjusted when the shape of the vehicle and the shape of the vehicle door are different. However, it is possible to provide a standard for maximizing the first opening angle X and minimizing the second opening angle Y while keeping the shape of the vehicle constant. Furthermore, automatic opening and closing of the front door of the vehicle can also be realized based on the door device 300.
