[0053] In the description of this specification, specific features, structures, materials or characteristics may be combined in an appropriate manner in any one or more embodiments or examples.
[0054] In some embodiments, as Figure 1-8 As shown, the present disclosure provides a limiter, comprising:
[0055] A first connecting rod 604 , one end of which is adapted to be connected to a vehicle body locking bracket 605 via a first rotating shaft 606 ; and
[0056] The driving assembly is connected to the other end of the first connecting rod 604 to drive the first connecting rod 604 to rotate around the first rotation axis 606.
[0057] Compared with the related technology in which the connecting rod is connected to the car body through a spherical pair, although the connecting rod has two degrees of freedom, it also causes the size of the connecting rod telescopic hole on the car door to increase, making it easier for sand and dust to enter the limiter, making the limiter more prone to abnormal noise and more easily damaged.
[0058] The first connecting rod 604 of the present invention is connected to the vehicle body locking bracket through the first rotating shaft 606. Although the first connecting rod 604 has only one degree of freedom, the size of the connecting rod telescopic hole of the vehicle door can be reduced, sand and dust are not easy to enter the limiter, the dustproof effect is enhanced, and the probability of abnormal noise of the limiter is relatively low; at the same time, it is not easy to be damaged.
[0059] In the stopper provided by the disclosed embodiment, a first connecting rod 604 is connected to the vehicle body locking bracket via a first rotating shaft 606. The driving assembly drives the first connecting rod 604 to rotate (e.g., horizontally) about the first rotating shaft 606. Since the first connecting rod 604 is limited to rotation about the first rotating shaft 606, the size of the connecting rod telescopic hole in the inner door panel can be reduced (e.g., the vertical size of the connecting rod telescopic hole can be reduced). This prevents dust from entering the stopper, enhancing dustproofing, and making and damaging the stopper.
[0060] To facilitate driving the first connecting rod 604 , in some embodiments, the limiter further includes: a second connecting rod 603 , one end of the second connecting rod 603 is connected to the other end of the first connecting rod 604 , and the other end of the second connecting rod 603 is connected to the driving assembly.
[0061] By providing the second connecting rod 603 , the driving assembly drives the first connecting rod 604 to rotate via the second connecting rod 603 , which can simplify the design of the first connecting rod 604 and reduce the complexity of the structure.
[0062] To facilitate driving the first connecting rod 604 , in some embodiments, the rotation axis of the first connecting rod 604 relative to the vehicle body locking bracket 605 is perpendicular to the rotation axis of the second connecting rod 603 relative to the first connecting rod 604 .
[0063] The rotation axis of the second link 603 relative to the first link 604 can be set to various suitable directions. In order to simplify the structure of the limiter, the rotation axis of the second link 603 relative to the first link 604 can be perpendicular to the rotation axis of the first link 604 relative to the vehicle body locking bracket 605, so that the first link 604 can be rotated in another direction (such as vertical direction) through the second link 603, which can effectively reduce the opening size of the vehicle door setting and improve the service life of the limiter.
[0064] The limiter provided in the embodiment of the present disclosure is provided with a first connecting rod 604 and a second connecting rod 603, and the rotation axis of the first connecting rod 604 relative to the vehicle body locking bracket 605 is perpendicular to the rotation axis of the second connecting rod 603 relative to the first connecting rod 604, thereby being able to realize rotation in two different directions, playing a role similar to a universal joint, facilitating the arrangement of the drive assembly, and thereby simplifying the structure of the limiter and reducing the volume of the limiter.
[0065] In some embodiments, Figure 1-8 The XYZ coordinate system in can refer to the vehicle's XYZ axis coordinate system, where:
[0066] X-axis: usually refers to the longitudinal direction of the vehicle, with the positive direction pointing to the front of the vehicle.
[0067] Y-axis: refers to the lateral direction of the vehicle, with the positive direction pointing to the driver's left.
[0068] Z axis: refers to the vertical direction, with the positive direction pointing upwards of the vehicle.
[0069] In order to facilitate driving the second connecting rod 603 to rotate, Figure 1 、 5 As shown in FIG6 , in some embodiments, the limiter further includes: a third connecting rod 602 , one end of the third connecting rod 602 is connected to the other end of the second connecting rod 603 , and the other end of the third connecting rod 602 is connected to the driving assembly.
[0070] That is, the driving assembly drives the second connecting rod 603 to rotate via the third connecting rod 602 , so that the driving assembly can be arranged more flexibly to reduce the volume of the limiter.
[0071] Through the reasonable arrangement of the first connecting rod 604, the second connecting rod 603 and the third connecting rod 602, the present invention can basically set the three connecting rods in the same plane as the limiting body of the limiter. Compared with the structures such as belts and pulleys or screw rods and gear pairs in related technologies, the limiter of the present invention has a simple structure and occupies little space.
[0072] In order to meet the requirement of the first connecting rod 604 swinging along the Y direction, in some embodiments, as Figure 1 、 5 As shown in , 6 and 8, one end of the third link 602 is connected to the other end of the second link 603 through a connecting member, and the connecting member enables the direction of the second link 603 relative to the rotation axis of the third link 602 to be variable.
[0073] That is, compared with the two connecting rods connected by a rotating shaft and can only rotate in a single direction, the second connecting rod 603 of the present invention can rotate in more directions relative to the third connecting rod 602 through a connecting member, thereby meeting the need for the first connecting rod 604 to swing along the Y direction, thereby achieving the function of limiting the door.
[0074] In order to meet the need of the first connecting rod 604 swinging along the Y direction, as shown in FIG. Figure 1 、 5 As shown in Figures 6 and 8, in some embodiments, one end of the third connecting rod 602 is connected to the other end of the second connecting rod 603 through a spherical pair.
[0075] In order to meet the requirement of the first connecting rod 604 swinging along the Y direction, in some embodiments, the spherical pair includes: a radial spherical bearing, a fisheye bearing or a ball and socket joint.
[0076] In order to meet the requirement of the first connecting rod 604 swinging along the Y direction, in some embodiments, one end of the third connecting rod 602 is connected to the other end of the second connecting rod 603 through a radial spherical bearing 6021.
[0077] The radial spherical plain bearing 6021 may be disposed in the circular hole 6022 of the third connecting rod 602 , and the third rotating shaft 608 passes through the radial spherical plain bearing 6021 and is connected to the other end of the second connecting rod 603 .
[0078] That is, compared with the two connecting rods connected by a rotating axis and can only rotate in a single direction, the second connecting rod 603 of the present invention can rotate in more directions relative to the third connecting rod 602 through a spherical pair, thereby meeting the need for the first connecting rod 604 to swing along the Y direction, and thus realizing the function of limiting the door.
[0079] In order to better drive the third link 602, in some embodiments, as Figure 1 、 5As shown in , 6 and 7 , the driving assembly includes: a power device 500 and a first reduction device, and the power device 500 is connected to the other end of the third connecting rod 602 through the first reduction device.
[0080] That is, the power device 500 drives the third connecting rod 602 to move through the first reduction gear, thereby providing a suitable reduction ratio to increase the driving torque of the power device 500 to meet the working requirements of the limiter.
[0081] The first reduction gear may be any suitable reduction gear, such as a bevel gear reducer. In order to facilitate driving the third connecting rod 602 and facilitating the arrangement of the drive assembly, in some embodiments, such as Figure 1 、 5 As shown in , 6 and 7 , the first reduction device includes: a worm gear reducer, the worm 601 of the worm gear reducer is connected to the power device 500 , and the worm wheel 400 of the worm gear reducer is connected to the other end of the third connecting rod 602 .
[0082] That is, the power device 500 can drive the third connecting rod 602 to move through the worm gear reducer, while providing a sufficient reduction ratio, it can effectively reduce the Y-axis size of the limiter and reduce the volume of the limiter, thereby facilitating the arrangement of the limiter.
[0083] The third connecting rod 602 can be of various suitable shapes, such as a straight rod. In order to facilitate the connection between the third connecting rod 602 and the worm gear 400, in some embodiments, 1, 5, 6 and 8, the third connecting rod 602 includes a first connecting portion 6024, a second connecting portion and a third connecting portion. The first connecting portion 6024 and the second connecting portion are not in the same plane. The first connecting portion 6024 and the second connecting portion are connected through the third connecting portion. A first groove 402 is provided on one side of the worm gear 400, and the first connecting portion 6024 is installed in the first groove 402.
[0084] The first groove 402 and the first connecting portion 6024 provided in the embodiment of the present disclosure can not only effectively reduce the size of the limiter in the Y direction, but also prevent the worm 601 and the third connecting rod 602 from rotating in interference.
[0085] In order to facilitate the connection between the third connecting rod 602 and the worm gear 400, in some embodiments, 1, 5 and 6, a second groove 403 is provided on the other side of the worm gear 400, and the first connecting part 6024 is connected to the worm gear 400 through a bolt and nut, and at least a portion of the nut is located in the second groove 403.
[0086] The bolt can pass through the hole 6023 provided on the first connecting portion 6024 and connect with the nut in the second groove 403 .
[0087] The second groove 403 provided on the side of the worm gear 400 can accommodate at least part of the nut, thereby effectively reducing the Y-direction space occupied by the bolts and nuts, which is conducive to reducing the volume of the limiter.
[0088] To facilitate installation, in some embodiments, such as Figure 1-3 As shown, the limiter further includes: a housing, in which the first connecting rod 604, the second connecting rod 603 and the driving assembly are installed, and a portion of the first connecting rod 604 extends out of the housing.
[0089] The first connecting rod 604, the second connecting rod 603 and the driving assembly are installed through the shell, which facilitates installation and meets the requirements of the limiter for being waterproof and dustproof.
[0090] In order to limit the maximum opening angle of the door, in some embodiments, such as Figure 5 and 6 As shown, the limiter further includes: a limit device 609, which is used to limit the length of the first connecting rod 604 or the second connecting rod 603 extending out of the housing.
[0091] That is, the length of the first connecting rod 604 or the second connecting rod 603 extending out of the housing is limited by the limiting device 609, so that the maximum opening angle of the vehicle door can be controlled.
[0092] In order to limit the maximum opening angle of the door, in some embodiments, such as Figure 5 and 6 As shown, the limiting device 609 is provided on the first connecting rod 604 or the second connecting rod 603 .
[0093] That is, by providing the limiting device 609 on the first connecting rod 604 or the second connecting rod 603, the limiting function can be achieved simply and effectively.
[0094] The limiting device 609 can be any suitable device to facilitate the limiting. In order to simplify the structure, in some embodiments, such as Figure 5 and 6 As shown, the limiting device 609 includes: a limiting protrusion.
[0095] That is, a limiting protrusion can be provided on the first connecting rod 604 or the second connecting rod 603, so as to achieve the limiting function simply and conveniently.
[0096] In order to facilitate limiting the swing of the first connecting rod 604, in some embodiments, the shell includes: a connecting plate 2021, a limiting hole 2022 is provided on the connecting plate 2021, one end of the first connecting rod 604 passes through the limiting hole 2022, and the connecting plate 2021 is suitable for blocking the limiting protrusion from passing through the limiting hole 2022.
[0097] By properly setting the size of the limiting hole 2022, the swing of the first connecting rod 604 can be effectively limited. The connecting plate 2021 can also prevent the limiting protrusion from passing through the limiting hole 2022, thereby also limiting the length of the first connecting rod 604 or the second connecting rod 603 extending out of the housing.
[0098] That is, when the limiting protrusion contacts the connecting plate 2021, the vehicle door reaches the maximum opening angle.
[0099] In order to facilitate the door limit, in some embodiments, such as Figure 3 As shown, the connecting plate 2021 is suitable for connecting to the vehicle door.
[0100] That is, the limiter can be installed on the vehicle door through the connecting plate 2021, thereby achieving the limitation of the vehicle door.
[0101] In order to facilitate the installation of the stopper and the door, in some embodiments, such as Figure 4 As shown, the limiter further includes: a vehicle door locking bracket 300 , one end of the vehicle door locking bracket 300 is suitable for connecting to the vehicle door, and the other end of the vehicle door locking bracket 300 is connected to the connecting plate 2021 .
[0102] The door lock bracket 300 can be connected to the connecting plate 2021 in various suitable ways. In some embodiments, such as Figure 3 and 4 As shown, the connecting plate 2021 can be provided with a bolt hole 2027, and the door locking bracket 300 can be provided with a countersunk hole 304 so as to be connected by a bolt passing through the countersunk hole 304 and the bolt hole 2027, thereby fixing the connecting plate 2021 on the door locking bracket 300.
[0103] The connecting plate 2021 is connected to the vehicle door via the vehicle door locking bracket 300 , which can simplify the structure of the connecting plate 2021 and facilitate the processing of the shell.
[0104] The door lock bracket 300 can be connected to the door in various suitable ways. In some embodiments, for example, Figure 4 As shown, the vehicle door locking bracket 300 can be connected to the vehicle door via bolts 301 and bolts 302 .
[0105] In order to facilitate the connection between the first connecting rod 604 and the vehicle body locking bracket 605 , a bracket limiting hole 303 is provided on the vehicle door locking bracket 300 so that the first connecting rod 604 passes through the bracket limiting hole 303 and is connected to the vehicle body locking bracket 605 .
[0106] To facilitate the installation of the first connecting rod 604, the second connecting rod 603 and the driving assembly, in some embodiments, the shell includes: a first shell 201 and a second shell 202, the first shell 201 and the second shell 202 enclose an installation cavity, and the first connecting rod 604, the second connecting rod 603 and the driving assembly are installed in the installation cavity.
[0107] In order to ensure waterproof and dustproof effects, the connecting plate 2021 can be connected to or integrally formed with the first shell 201 or the second shell 202. In some embodiments, such as Figure 3 As shown, the connecting plate 2021 and the second shell 202 are integrally formed.
[0108] The two shells enclose a mounting cavity to mount the first connecting rod 604, the second connecting rod 603 and the driving assembly, thereby making it easy and convenient to mount the first connecting rod 604, the second connecting rod 603 and the driving assembly, and reducing the difficulty of manufacturing the shells.
[0109] To facilitate the installation of the drive assembly, the drive assembly can be various suitable drive devices. In some embodiments, the drive assembly includes: a power unit 500 and a first reduction device. The power unit 500 is connected to the other end of the third connecting rod 602 through the first reduction device. The power unit 500 is fixed on the first shell 201 and / or the second shell 202, and the first reduction device is supported on the first shell 201 and / or the second shell 202.
[0110] The power unit 500 can be directly fixedly mounted on the first housing 201 and / or the second housing 202, while the first reduction gear can be supported on the first housing 201 and / or the second housing 202. While ensuring the movement of the driving connecting rod, the driving assembly can also be effectively fixed to prevent unnecessary movement of the driving assembly, thereby enhancing the limiting effect of the limiter.
[0111] In order to facilitate the fixing of the power device 500 , in some embodiments, a mounting groove is provided on the first housing 201 or the second housing 202 , and the power device 500 is fixedly installed in the mounting groove.
[0112] By installing and fixing the power device 500 through the installation groove, the power device 500 can be prevented from moving, thereby effectively ensuring the working reliability of the limiter.

[0117] At the same time, a limiting groove (such as Figure 3 The limiting grooves 2024, 2025 and 2026) or limiting protrusions shown are used to install the first reduction gear and the second reduction gear 502 through the limiting grooves. At the same time, the limiting grooves or limiting protrusions can limit the movement of the limiting blocks, thereby preventing the drive assembly from moving.
[0118] The motor 501 and the second reduction gear 502 can cooperate with the first reduction gear to improve the reduction ratio and the working performance of the limiter.
[0119] In order to facilitate the support of the reduction device, in some embodiments, the first reduction device includes: a worm gear reducer, the worm wheel 400 of the worm gear reducer is supported on the first housing 201 and the second housing 202 through a supporting device, and the worm 601 of the worm gear reducer is supported on the first housing 201 or the second housing 202.
[0120] The supporting device can be any suitable device. In some embodiments, Figure 5 and 6 As shown, the supporting device can be a support shaft 401, and a support shaft 401 can be provided on each side of the worm gear 400. The first housing 201 and the second housing 202 can be provided with a support groove 2023 and a support groove 2011 respectively. Through the cooperation between the support shaft 401 and the support groove, the worm gear 400 can be effectively supported.
[0121] In some embodiments, as Figure 1 As shown, a support hole may be provided on the first housing 201 or the second housing 202 to facilitate supporting the worm 601 .
[0122] To facilitate processing, in some embodiments, as Figure 1 and 2 As shown, the housing further includes: a third housing 203 , and the first housing 201 , the second housing 202 and the third housing 203 form a mounting cavity.
[0123] To facilitate processing, in some embodiments, as Figure 1 and 2 As shown, an opening is formed at one end of the first shell 201 and the second shell 202 for mounting the driving assembly, and the third shell 203 is used to block the opening.
[0124] In some embodiments, the second shell 202 can be provided with an installation groove to install the first connecting rod 604, the second connecting rod 603 and the drive assembly. The first shell 201 can be constructed as a cover plate, and an opening is formed at one end of the first shell 201 and the second shell 202 for installing the drive assembly (such as the motor 501). The third shell 203 can be constructed as a blocking plate, so that it can be fixed with the first shell 201 and the second shell 202 and block the opening, thereby improving the waterproof and dustproof performance of the limiter.
[0125] The first housing 201 and the second housing 202 can be fixed by various suitable means, such as by snap fastening. Figure 3 As shown, bolt holes 2028 may be provided on the second housing 202 so as to fix the first housing 201 and the second housing 202 by bolts.
[0126] The third housing 203 can be fixed to the first housing 201 and the second housing 202 in various suitable ways, such as Figure 3 As shown, bolt holes 2029 may be provided on the second housing 202 so as to fix the third housing 203 to the first housing 201 and the second housing 202 by bolts.
[0127] To facilitate rotation, in some embodiments, one end of the first link 604 is adapted to be connected to the vehicle body locking bracket 605 via a first rotating shaft 606 , and one end of the second link 603 is connected to the other end of the first link 604 via a second rotating shaft 607 .
[0128] That is, the first link 604 and the vehicle body locking bracket 605 , as well as the first link 604 and the second link 603 can be connected via a rotation axis, thereby facilitating the first link 604 and the second link 603 to rotate around the first rotation axis 606 and the second rotation axis 607 respectively.
[0129] In some embodiments, threads may be provided on the first rotating shaft 606 and the second rotating shaft 607 to facilitate installation of nuts to prevent them from falling off.
[0130] In some embodiments, as Figure 1-8 As shown, the motor 501, the second reduction device 502, the worm gear reducer, the third connecting rod 602, the second connecting rod 603 and the third connecting rod 604 are installed in the same plane (such as a plane parallel to the vehicle door), so the Y-direction size of the limiter can be reduced and the volume of the limiter can be reduced.
[0131] In the stopper provided by the disclosed embodiment, a first connecting rod 604 is connected to the vehicle body locking bracket via a first rotating shaft 606. The driving assembly drives the first connecting rod 604 to rotate about the first rotating shaft 606. Since the first connecting rod 604 can only move about the first rotating shaft 606, the size of the connecting rod telescopic hole in the inner door panel can be reduced. This prevents dust from entering the stopper, enhances dustproofing, and reduces the risk of abnormal noise and damage.
[0132] The limiter provided in the embodiment of the present disclosure is provided with a first connecting rod 604 and a second connecting rod 603, and the rotation axis of the first connecting rod 604 relative to the vehicle body locking bracket 605 is perpendicular to the rotation axis of the second connecting rod 603 relative to the first connecting rod 604, thereby being able to realize rotation in two different directions, playing a role similar to a universal joint, facilitating the arrangement of the drive assembly, and thereby simplifying the structure of the limiter and reducing the volume of the limiter.
[0133] The present disclosure also provides a vehicle door, comprising: a limiter provided in any of the above embodiments.
[0134] The present disclosure also provides a vehicle, comprising: a limiter as provided in any of the above embodiments, or a vehicle door as provided in the above embodiments.
[0135] The embodiments of the present disclosure are described above in conjunction with the accompanying drawings, but the present disclosure is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the guidance of the present disclosure, ordinary technicians in this field can also make many forms without departing from the scope of protection of the purpose of the present disclosure and the claims, all of which are protected by the present disclosure.
