The entire contents of the above disclosure are incorporated herein by reference.

[0002] The present disclosure relates to the field of vehicle component technology, and in particular to support rod assemblies, vehicle door assemblies, and vehicles. [Background technology]

[0003] As the number of vehicles continues to grow, people's requirements for vehicles are evolving from the initial focus on transportation to focus on appearance, comfort, and electrification. In this context, vehicle doors have gradually evolved from their original manual operation to electrification and intelligence, significantly improving the vehicle user experience. Butterfly doors are revolving doors or dihedral doors that rotate on a fixed axis, and different angles of inclination result in different postures. As a specially shaped vehicle door, butterfly doors have a different opening and closing method than traditional vehicle doors. However, the support rods in related technologies are unable to reliably support butterfly doors and are unable to provide sufficient force to effectively support the opening and closing of butterfly doors.

DETAILED DESCRIPTION OF THE INVENTION

[0024] Specific implementation examples of the present disclosure are described in detail below with reference to the accompanying drawings. It should be understood that the specific implementation examples described herein are merely used to explain and illustrate the present disclosure and are not intended to limit the present disclosure.

[0025] In this disclosure, unless otherwise specified, directional terms such as "upper, lower, front, and rear" generally refer to the upper, lower, front, and rear directions of a vehicle in a normal configuration. For example, the direction of the front of the vehicle is the front, the direction of the rear of the vehicle is the rear, upper is the top of the vehicle, and lower is the bottom of the vehicle. "Inner and outer" refer to the inside and outside of the part in question. Furthermore, terms such as "first" and "second" are used in this disclosure to distinguish one element from another, and are not terms of order or importance.

[0026] As described above, for special vehicle doors such as butterfly doors, the opening and closing method of the butterfly door is different from the existing conventional opening and closing method of vehicle doors. In addition, butterfly doors generally have a large weight, and the support rods in the related art cannot reliably support the butterfly door and cannot provide sufficient force to effectively support the opening and closing of the butterfly door.

[0027] In consideration of this, the present disclosure provides a support rod assembly 10, as shown in Figures 1 to 9. The support rod assembly 10 can be applied to a vehicle door 20 of a vehicle, particularly a butterfly door. The support rod assembly 10 includes a first support rod 11 and a second support rod 12, one end of the first support rod 11 and one end of the second support rod 12 configured to be separately hinged to the vehicle door 20, and the other end of the first support rod 11 and the other end of the second support rod 12 configured to be separately hinged to a vehicle body 200, and at least one of the first support rod 11 and the second support rod 12 is an electric support rod.

[0028] The support rod assembly 10 provided in the present disclosure uses a two-support rod solution, i.e., a first support rod 11 and a second support rod 12. When the support rod assembly 10 is applied to a vehicle door 20 (such as a butterfly door) of a vehicle 1000, it is beneficial to improve the support strength of the support rod assembly 10. In this way, even if the vehicle door 20 (especially a butterfly door) has a large weight, the support rod assembly 10 provided in the present disclosure is beneficial to ensure a support effect on the vehicle door 20 and easily provide a force for normal opening and closing of the vehicle door 20.

[0029] In addition, in the present disclosure, since at least one of the first support rod 11 and the second support rod 12 is an electric support rod, the vehicle door 20 (e.g., a butterfly door) is opened and closed electrically, thereby improving the user's door opening and closing operation feel.

[0030] It should be noted that the support rod assembly 10 of the present disclosure, in addition to being applied to butterfly doors, can also be applied to other types of vehicle doors, such as scissor doors, which is not a limitation of the present disclosure.

[0031] In the present disclosure, only one of the first support rod 11 and the second support rod 12 may be an electric rod, or both of the first support rod 11 and the second support rod 12 may be electric rods. This is not a limitation of the present disclosure. Optionally, in an embodiment of the present disclosure, one of the first support rod 11 and the second support rod 12 is an electric support rod and the other is a mechanical support rod. This is beneficial for providing sufficient support for opening and closing the vehicle door 20 (e.g., a butterfly door) and for reducing costs.

[0032] The specific connection locations of the first support rod 11, the second support rod 12, the vehicle body 200, and the vehicle door 20 are not limited in this disclosure. For example, one end of the first support rod 11 and one end of the second support rod 12 may be located near a hinge joint used by the vehicle door 20 hinged to the vehicle body 200, and the other end of the first support rod 11 and the other end of the second support rod 12 may be located near a connection between the lower end of a support pillar A of the vehicle 1000 and the door sill.

[0033] In a specific arrangement, the arrangement design and adjustment of the mounting area can be made based on parameters such as the mass and center of gravity of the vehicle door 20 (such as a butterfly door) to match the opening and closing operation of the vehicle door 20 and ensure that the first support rod 11 and the second support rod 12 do not interfere with each other during the movement process. In addition, to ensure aesthetics, it is best to ensure that the two support rods are parallel in real time during the movement process.

[0034] Based on this, as shown in FIGS. 1 to 3, the first support rod 11 and the second support rod 12 may be arranged along the longitudinal direction of the vehicle 1000, and the connection line between the first support rod 11 and the second support rod 12 may be parallel to the longitudinal center plane of the vehicle 1000. That is, the first support rod 11 and the second support rod 12 may be located on an arrangement line parallel to the longitudinal center plane of the vehicle 1000. This is beneficial for matching the opening and closing operation of the vehicle door 20 (such as a butterfly door) and ensuring that the first support rod 11 and the second support rod 12 do not interfere with each other during movement. In addition, parallelism can be ensured for aesthetic reasons.

[0035] As shown in FIGS. 1 to 4 , the first support rod 11 may be located rearward of the second support rod 12 along the longitudinal direction of the vehicle 1000, and the heights of the first support rod 11 and the second support rod 12 may be designed so that the height of the first support rod 11 is greater than the height of the second support rod 12 when the vehicle door is in an open state. The rear side of the second support rod 12 refers to the side of the second support rod 12 that is hinged to the vehicle body 200 and faces away from the vehicle door 20. In other words, when the support rod assembly 10 is attached to the vehicle body 200 and the vehicle door 20, the second support rod 12 is located in front of the first support rod 11 in the longitudinal direction of the vehicle. In this embodiment, when the vehicle door is in an open state, the first support rod 11 and the second support rod 12 are located on an alignment line parallel to the longitudinal center plane of the vehicle, and the height of the first support rod 11 is greater than the height of the second support rod 12. In this way, when the vehicle door is in an open position and is viewed from the rear of the vehicle towards the front of the vehicle (i.e., viewed from a rearward perspective), as shown in Figure 5, it is beneficial to allow the second support rod 12 to be hidden by the first support rod 11 at the rear, thereby helping to further improve aesthetics.

[0036] Optionally, the height of the first support rod 11 may also be greater than the height of the second support rod 12 when the vehicle door is in the closed state.

[0037] In this specification, it can be understood that the state in which the vehicle door 20 is open may refer to a state in which the vehicle door 20 is in a fully open position, or may refer to a state in which the vehicle door 20 is in any open position.

[0038] In this case, the first support rod 11 may be an electric support rod, and the second support rod 12 may be a mechanical support rod. That is, the electric rod is located behind the mechanical rod. The front end of the vehicle door 20 (e.g., a butterfly door) is hinged to the vehicle body 200, and the electric support rod is located at the rear to help control one end of the electric support rod hinged to the vehicle door 20 (e.g., the second end 1152 of the lower electric support rod) away from the hinge joint between the vehicle door 20 and the vehicle body 200. By using the principle of leverage, this configuration makes it easy to adjust the opening degree of the vehicle door 20 with a small force.

[0039] During the process of opening the vehicle door 20, as the mass, center of mass, and opening angle of the vehicle door 20 change, the center of mass is lifted during the movement process, which makes it very likely that the vehicle door 20 will fall quickly and injure a part of the body of a vehicle occupant. In consideration of this, in the embodiment of the present disclosure, when the first support rod 11 and / or the second support rod 12 (e.g., the first support rod 11) configured as an electric support rod is in an unpowered state, the support rod assembly 10 is configured so that the end of the electric support rod that is hinged to the vehicle door (e.g., the second end 1152 of the lower electric support rod) can come to a stop at any position within a preset stroke, thereby preventing the vehicle door 20 from falling quickly and injuring a part of the body of a vehicle occupant. That is, in this embodiment, the electric support rod is designed as an electric support rod with a stop function. To this end, it can be seen from the torque balance equation that the total mechanical torque MF provided by the support rod assembly 10 (including the mechanical torques provided by the first support rod 11 and the second support rod 12) can be balanced with the current gravitational torque MG of the vehicle door 20. In this way, it is ensured that the vehicle door can be manually opened and closed and can be stopped midway at any position if the power supply or motor 111 is lost after the electric signal for the powered support rod is issued.

[0040] The specific structure of the electric support rod is not limited in this disclosure. Optionally, as shown in FIGS. 4, 6, and 7, the electric support rod may include a motor 111, a limiting member 112, an outer sleeve 113, a first inner pipe 1141, a first end 1151 of the electric support rod, and a second end 1152 of the electric support rod. The first inner pipe 1141 is disposed inside the outer sleeve 113 so as to be movable along the axial direction of the outer sleeve 113. As a result, the length by which the end of the first inner pipe 1141 extends from the outer sleeve 113 can be adjusted. That is, referring to FIGS. 2 and 6, the length by which the end of the first inner pipe 1141 that is hinged to the vehicle body extends from the outer sleeve 113 can be adjusted, thereby changing the overall length of the electric support rod. The motor 111 and the limiting member 112 are fixedly disposed inside the outer sleeve 113. The first end 1151 of the electric support rod is connected to one end of the first inner pipe 1141 (i.e., the end remote from the second end 1152 of the electric support rod) and configured to be hinged to the vehicle body 200, and the second end 1152 of the electric support rod is connected to one end of the outer sleeve 113 (i.e., the end remote from the first end 1151 of the electric support rod) and configured to be hinged to the vehicle door 20. The output shaft of the motor 111 is transmission-connected to the other end of the first inner pipe 1141 and drives the first inner pipe 1141 to move along the axial direction of the outer sleeve 113. The limiting member 112 is configured to lock the relative position of the first inner pipe 1141 and the outer sleeve 113 when the motor 111 is in an unpowered state, i.e., the first inner pipe 1141 and the outer sleeve 113 are locked in both the axial and circumferential directions, so that the second end 1152 of the electric support rod can stop midway at any position within its preset stroke.

[0041] The manner of the power transmission connection between the motor 111 and the first inner pipe 1141 and the mounting position of the limiting member 112 are not limited in the present disclosure. Optionally, as shown in FIGS. 6 and 7 , the electric support rod may further include a joint 116 and a lead screw 117. The output shaft of the motor 111 is power transmission connected to the lead screw 117 by the joint 116. The first inner pipe 1141 is fitted around the lead screw 117 to form a lead screw nut mechanism together with the lead screw 117. That is, the first inner pipe is configured as a nut of the lead screw nut mechanism, and the lead screw 117 is configured as a lead screw of the lead screw nut mechanism. The limiting member 112 is configured to limit the rotation of the lead screw 117 when the motor 111 is in an unpowered state, locking the first inner pipe 1141 within the outer sleeve 113 when the motor 111 is in an unpowered state, so that the second end 1152 of the motorized support rod can come to rest midway at any position within its preset travel.

[0042] During operation, the output shaft of the motor 111 rotates forward or backward, and transmits power to the lead screw 117 using the joint 116 to drive and rotate the lead screw 117. During the rotation of the lead screw 117, the first inner pipe 1141 moves along the axial direction of the lead screw to achieve expansion and contraction, thereby adjusting the position of the second end 1152 of the electric support rod. During this process, the output shaft of the motor 111, the joint 116, and the lead screw 117 only rotate, but do not move axially.

[0043] In addition to the above-described case in which the rotation of the lead screw 117 is limited by setting the limiting member 112, and as a result, the second end 1152 of the motorized support rod can be stopped midway at any position, it can be understood that in other embodiments of the present disclosure, a motor 111 with a built-in locking structure may also be used. When the motor 111 stops rotating forward or backward, the built-in locking structure can be used to limit the rotation of the output shaft of the motor 111.

[0044] 6 and 7, the electric support rod may further include a mounting pipe 118, a partition plate 119, a second inner pipe 1142, and a first spring 120 (such as a coil spring). The mounting pipe 118 is fixedly disposed inside the outer sleeve 113, and an end of the mounting pipe 118 is connected to a second end 1152 of the electric support rod. The motor 111, the joint 116, and the partition plate 119 are axially disposed in this order inside the mounting pipe 118. The second inner pipe 1142 is fitted around the mounting pipe 118 and is located between the mounting pipe 118 and the outer sleeve 113. The end of the second inner pipe 1142 remote from the motor 111 is connected to the first end 1151 of the electric support rod. The first spring 120 is looped around the outside of the first inner pipe 1141, with one end of the first spring 120 connected to the partition plate 119 and the other end connected to the second inner pipe 1142. In this way, when the first end 1151 of the electric support rod moves along the axial direction of the outer sleeve 113, the second inner pipe 1142 and the other end of the coil spring can be driven to move along the same direction. During this process, the first spring 120 is stretched or compressed. The first spring 120 provides elastic force during the movement of the first inner pipe 1141 and the second inner pipe 1142, helping to make the movement of the first inner pipe 1141 and the second inner pipe 1142 smoother.

[0045] In this embodiment, referring to Figures 6 and 7, the first inner pipe 1141, a portion of the mounting pipe 118 near the first end 1151 of the electrical support rod, and a portion of the second inner pipe 1142 can function as guides for the first spring 120 to avoid radial bending instability during the process of tensioning and compressing the spring 120.

[0046] 7, the mounting pipe 118 may include a large diameter portion and a small diameter portion. The motor 111, the coupling 116, and the restrictor 112 may be disposed in the large diameter portion. The small diameter portion may be located between the first inner pipe 1141 and the second inner pipe 1142.

[0047] 6 and 7, the electric support rod may further include a reducer 1101 disposed on the mounting pipe 118. The reducer 1101 is located between the motor 111 and the limiting member 112 in the axial direction of the mounting pipe 118.

[0048] The output shaft of the motor 111 is connected to a reducer 1101 to reduce the rotation speed of the motor 111 .

[0049] The specific structure of the limiting member 112 is not limited in the present disclosure. As shown in FIGS. 7 and 8 , in an embodiment of the present disclosure, the limiting member 112 can include a cylindrical housing 1121 and a plurality of friction plates 1122, the plurality of friction plates 1122 being arranged in a stacked manner inside the cylindrical housing 1121 along the axial direction of the cylindrical housing 1121, the lead screw 117 penetrating the cylindrical housing 1121 and positioned on the plurality of friction plates 1122 within the housing, and the plurality of friction plates 1122 being configured to provide a brake that limits the rotation of the lead screw 117 when the motor 111 is in an unpowered state. In this embodiment, the plurality of friction plates 1122 include vias 1123, and the lead screw is frictionally fitted with the inner wall of the via 1123. The plurality of friction plates 1122 can slow down and stop the rotating lead screw 117 by friction between the sheets when the motor 111 is in an unpowered state.

[0050] 7 and 8, the side wall of the cylindrical housing 1121 may include a protrusion 1124 having a first plug-in segment 1125 protruding from one of the end faces of the cylindrical housing 1121 and a second plug-in segment 1126 located on the side wall. The first plug-in segment 1125 may be configured to be connected to a socket of the reducer 1101, and the second plug-in segment 1126 may be configured to be inserted into and mate with a groove (not shown) in the inner wall of the mounting pipe 118 to connect and restrict the restricting member 112 in the axial and circumferential directions.

[0051] The specific structure of the mechanical support rod (such as the second support rod 12) is also not limited in the present disclosure. Optionally, as shown in FIG. 9 , in an embodiment of the present disclosure, the first support rod 11 or the second support rod 12 (e.g., the second support rod) configured as a mechanical support rod may be a balance rod, which includes a balance rod first end 121, a balance rod inner pipe 123, a gas spring 125, a balance rod outer pipe 124, a second spring 126, and a balance rod second end 122. The balance rod first end 121 is connected to the end of the balance rod inner pipe 123 and configured to be hinged to the vehicle body 200, and the balance rod second end 122 is connected to the end of the balance rod outer pipe 124 and configured to be hinged to the vehicle door 20. The pressure cylinder 1251 of the gas spring 125 is located inside the outer pipe 124 of the balance rod and is connected to the second end 122 of the balance rod, and the piston rod 1252 of the gas spring 125 is connected to the first end 121 of the balance rod. A second spring 126 (such as a coil spring) is mounted on the outside of the gas spring 125, and one end of the second spring 126 is connected to the pressure cylinder 1251 and the other end is connected to an end of the inner pipe 123 of the balance rod that is configured to be connected to the first end 121 of the balance rod (i.e., the inner pipe 123 of the balance rod is at the right end in the drawing direction of FIG. 9 ). In this embodiment, the gas springs 125 in the balance rods are mounted in the balance rods and have a certain pressure, so that in the process of opening the vehicle door 20 and gradually extending the electric support rod (first support rod 11), the balance rods can be driven to extend in unison, so that the outer pipes 124 of the balance rods and the inner pipes 123 of the balance rods move relative to each other. Similarly, in the process of closing the vehicle door 20 and gradually shortening the electric support rod, the balance rods can be driven to shorten in unison, so that the outer pipes 124 of the balance rods and the inner pipes 123 of the balance rods move relative to each other.The working principle of the balance rod is well known to those skilled in the art and will not be described in detail again here.

[0052] By disposing the second spring 126, the second spring 126 is expanded or compressed when the first end 121 of the balance rod and the inner pipe 123 of the balance rod move along the axial direction of the outer pipe 124 of the balance rod. In this case, the second spring 126 provides an elastic force during the movement of the inner pipe 123 of the balance rod and the piston rod 1252 of the gas spring 125, which can help make the movement of the inner pipe 123 of the balance rod and the piston rod 1252 of the gas spring 125 smoother.

[0053] It can be understood that in other embodiments of the present disclosure, the mechanical support rod (eg, the second support rod 12) may be a gas spring type mechanical support rod.

[0054] According to the above-mentioned solution, the present disclosure adds mechanical energy storage in a limited installation space, which not only ensures the placement of the support rod mechanism in a limited design space, but also matches the opening and closing operation of the large-mass vehicle door 20 (e.g., butterfly door), and also realizes the electrification of the opening and closing of the vehicle door 20 (e.g., butterfly door).

[0055] As shown in FIGS. 1 to 6, a vehicle door assembly 100 is provided according to a second aspect of the present disclosure. The vehicle door assembly 100 includes a vehicle door 20 (such as a butterfly door) and the aforementioned support rod assembly 10. The vehicle door may be hinged to a vehicle body 200 by a hinge structure 40, with one end of a first support rod 11 and one end of a second support rod 12 being separately hinged to the vehicle door 20. Here, the hinge structure 40 may include, for example, the hinge 30 shown in FIGS. 1, 2, and 5, and the vehicle door 20 can rotate about a rotation centerline 31 of the hinge.

[0056] 1, according to another aspect of the present disclosure, there is provided a vehicle 1000. The vehicle 1000 includes the vehicle door assembly 100 described above.

[0057] The preferred implementation examples of the present disclosure have been described in detail above with reference to the accompanying drawings. However, the present disclosure is not limited to the specific details in the above implementation examples, and several simple modifications may be made to the technical solutions of the present disclosure within the technical concept of the present disclosure, and these simple modifications fall within the protection scope of the present disclosure.

[0058] Furthermore, it should be further noted that the specific technical features described in the above specific implementation examples may be combined in any suitable manner where not inconsistent, and in order to avoid unnecessary repetition, the various possible combinations are not separately described in this disclosure.

[0059] In addition, different implementation examples of the present disclosure may also be arbitrarily combined without departing from the spirit of the present disclosure, and these combinations shall still be considered as disclosed in the present disclosure.
