Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts, in particular to a multi-position back door limiter. Background Art

[0002] The opening of a general car back door does not have a limit function, and usually only has one limit on the hinge, so that the opening angle of the back door is fixed. After the back door is opened, the back door opens directly to the stop point under the action of the gas strut, which has many restrictions on daily vehicle use. For example, in urban logistics conditions, it is inconvenient for workers to carry goods for SUVs, MPVs, vans and other models, especially when the car is parked in a relatively narrow position at the rear, and the tailgate is prone to bumping when opened. The electric tailgate of high-end models can stop freely, but the cost is high and it is not suitable for the mass market. The existing multi-speed back door limiter is usually fixed to the edge of the car's door frame with the help of multiple sets of fastening bolts and other structures. However, when installing and removing the fastening bolts, maintenance personnel need to use external tools, and the steps are cumbersome and time-consuming when installing and removing multiple sets of fastening bolts continuously. Utility Model Content

[0003] The purpose of the utility model is to provide a multi-position back door limiter to solve the problems raised in the above background technology.

[0004] The technical solution of the utility model is: a multi-speed back door limiter, comprising a mounting base and two groups of limit plates, and the two groups of limit plates are centrally symmetrical, the two groups of limit plates are rotatably connected to the multi-speed back door limiter body, a threaded component is rotatably connected in the inner cavity of the limit plate, a threaded block is threadedly connected to the threaded component, and sliders are symmetrically fixedly connected at the upper and lower ends of the threaded block, a sliding rod is symmetrically fixedly connected to the inner cavity of the limit plate, and the slider is slidably arranged on the sliding rod, a constraint component that is mutually clamped with the threaded component is slidably arranged on the side wall of the inner cavity of the limit plate, a push plate 1 is fixedly connected to the side wall of the threaded block, and a fixing component that abuts against the push plate 1 is slidably arranged on the side wall of the inner cavity of the limit plate, and fixing grooves are symmetrically provided at both ends of the inner side of the mounting base.

[0005] Based on the above technical features: During installation, the staff will place the limit plate inside the mounting base and align the fixed end of the fixing component with the fixing groove:

[0006] Then the staff pulls the constraint assembly toward the outside of the limit plate, so that the constraint end of the constraint assembly is separated from the threaded assembly, thereby releasing the constraint assembly from the threaded assembly; then the staff twists the threaded assembly, and the set threaded block moves along the threaded direction of the threaded assembly, and the set threaded block drives the push plate 1 to move, and the set push plate 1 pushes the fixing assembly to move, so that the fixed end of the fixing assembly is inserted into the fixing groove, and the limit plate is fixed to the mounting base with the help of the fixing assembly; in this process, the set slider slides on the slide rod, and the slider is used to limit the threaded block during the movement;

[0007] The staff then loosened the constraint assembly, and the constraint end of the constraint assembly re-engaged with the threaded assembly under the action of its own elastic force, thereby restoring the limiting fixation of the constraint assembly on the threaded assembly. The set constraint assembly makes the threaded assembly less likely to loosen due to external vibrations.

[0008] Preferably, the threaded assembly comprises a threaded rod rotatably connected in the inner cavity of the limiting plate, and a toothed plate is fixedly connected to the rod body of the threaded rod.

[0009] Based on the above technical features: a worker twists the threaded rod, and the set threaded block moves along the thread direction of the threaded rod, and the set threaded block drives the push plate to move.

[0010] Preferably, a screw head is fixedly connected to one side of the threaded rod located outside the limiting plate.

[0012] Preferably, the constraint assembly includes a constraint rod slidably set on the side wall of the inner cavity of the limit plate, a circular plate is fixedly connected to the constraint rod body, a spring is wound around the constraint rod body, and the spring is connected between the circular plate and the side wall of the inner cavity of the limit plate, and the constraint rod is fixedly connected to a tooth block that is mutually engaged with the tooth plate on the side close to the tooth plate.

[0013] Based on the above technical features: the staff pulls the constraint rod toward the outside of the limit plate, and the set constraint rod drives the tooth block to separate from the tooth plate, thereby releasing the limit fixation of the tooth block on the threaded rod; after the fixing assembly completes the limit fixation of the limit plate, the staff loosens the constraint rod, and the set constraint end of the constraint rod re-engages with the tooth plate under the action of the elastic force of the spring, thereby restoring the limit fixation of the threaded rod by the tooth block, and the set tooth block makes the threaded rod less likely to loosen due to external vibration.

[0014] Preferably, a pull plate is fixedly connected to one side of the constraint rod located outside the limiting plate.

[0016] Preferably, the fixing assembly includes fixing rods symmetrically and slidably arranged on the side wall of the inner cavity of the limiting plate, and a push plate 2 abutting against the push plate 1 is fixedly connected between two groups of fixing rods located on one side of the inner cavity of the limiting plate, and a spring 2 is wound around the rod body of the fixing rod, and the spring 2 is connected between the push plate 2 and the side wall of the inner cavity of the limiting plate.

[0017] Based on the above technical features: the push plate one pushes the push plate two to move, and the push plate two drives the fixed rod to move, so that the fixed end of the fixed rod is inserted into the fixed groove, and the limit plate is fixed to the mounting base with the help of the fixed rod; in this process, the set slider slides on the slide rod, and the slider is used to limit the threaded block during the movement.

[0018] The utility model provides a multi-position back door stopper through improvement, which has the following improvements and advantages compared with the prior art:

[0019] First, the staff pulls the constraint assembly toward the outside of the limit plate, so that the constraint end of the constraint assembly is separated from the thread assembly, thereby releasing the constraint assembly from the thread assembly; then the staff twists the thread assembly, and the set thread block moves along the thread direction of the thread assembly, and the set thread block drives the push plate 1 to move, and the set push plate 1 pushes the fixing assembly to move, so that the fixed end of the fixing assembly is inserted into the fixing groove. This device fixes the limit plate on the mounting base with the help of the fixing assembly. During the later maintenance, the maintenance personnel can remove the limit plate from the mounting base without the help of external tools, and it takes a short time.

[0020] Second, the staff loosens the constraint component, and the constraint end of the constraint component re-engages with the threaded component under the action of its own elastic force, thereby restoring the limit fixation of the constraint component on the threaded component. The constraint component makes it difficult for the threaded component to loosen due to external vibration. BRIEF DESCRIPTION OF THE DRAWINGS
