Description

Technical Field

[0001] The present invention relates to the technical field of door opening limit, and more particularly, to a door opening limit lock structure. Background Art

[0002] In the prior art, the limit of the swing door mainly relies on the snap ring limit structure. After the swing door is pushed out, the door and the vehicle body are only connected by the middle rotating arm. Due to space limitations, it is often difficult to arrange the limit lock. The snap ring limit realizes the limit when the swing door is translated without a track by the limit mechanism of the snap ring mechanism entering the groove of the limit box in a force-closed state. However, this limit method has two major basic problems: one is that the limit durability is poor. After multiple door openings and closings, the limit mechanism will fail, far lower than the durability requirements of traditional front doors and sliding doors; the other is that the limit force decays seriously. As the number of uses increases, the deformation of the snap ring structure will cause the limit force to decrease, and even lead to limit failure, resulting in problems such as the swing door coming out. Therefore, we make improvements and propose a door opening limit lock structure. Summary of the Invention

[0003] The purpose of the present invention is to address the problems of poor durability of the snap ring limit and serious decay of the limit force currently existing.

[0004] To achieve the above-mentioned invention purpose, the present invention provides a door opening limit lock structure to improve the above problems.

[0005] Specifically, this application is as follows: A door opening limit lock structure for being installed on a swing door main body to realize the limit after the swing door main body is opened, including a limit lock main body, a limit lock mounting bracket, a first lower hinge arm hinge bracket, a limit lock catch, and a lower hinge arm main body installed on the swing door main body. Specifically: The limit lock mounting bracket is fixed on the swing door main body as the installation base of the limit lock main body, and the limit lock main body is installed on the limit lock mounting bracket; the limit lock main body cooperates with the limit lock catch when the swing door main body is opened to a specific position to realize the limit. The limit lock catch is fixed on the lower hinge arm main body, and the limit lock catch moves with the movement of the lower hinge arm main body. When the swing door main body is opened to the maximum opening degree, the limit lock catch can enter the limit lock main body to realize the locking.

[0006] As a preferred technical solution of this application, it further includes a second lower hinge arm hinge bracket, and the second lower hinge arm hinge bracket is combined with the lower hinge arm main body through a spherical hinge.

[0007] As a preferred technical solution of the present application, the first lower hinge arm hinge bracket is fixed to the swing door body, and the first lower hinge arm hinge bracket is rotatably combined with the lower hinge arm body to form the support and rotation of the lower part of the swing door body.

[0008] As a preferred technical solution of the present application, when the limit lock body catches the limit lock catch, the X-direction and Y-direction limits of the swing door body are realized.

[0009] As a preferred technical solution of the present application, the limit lock mounting bracket is welded to the swing door body.

[0010] As a preferred technical solution of the present application, it further includes an upper limit part. The limit part is arranged on the swing door body, and the limit part includes a first upper hinge arm limit hinge bracket, an upper hinge arm body, a second upper hinge arm limit hinge bracket and a limit boss.

[0011] As a preferred technical solution of the present application, both ends of the upper hinge arm body are rotatably connected to the first upper hinge arm limit hinge bracket and the second upper hinge arm limit hinge bracket respectively to form the upper support and rotation structure of the swing door body.

[0012] As a preferred technical solution of the present application, the first upper hinge arm limit hinge bracket and the swing door body are connected by bolts.

[0013] As a preferred technical solution of the present application, the limit boss is arranged on the upper hinge arm body, and a limit groove is arranged on the first upper hinge arm limit hinge bracket. The limit boss is inserted and matched with the limit groove when the swing door body is opened to the maximum opening degree to realize the Z-direction limit of the swing door body.

[0014] As a preferred technical solution of the present application, reinforcing ribs are arranged inside both the upper hinge arm body and the lower hinge arm body. The reinforcing ribs extend along the length direction or width direction of the upper hinge arm body and the lower hinge arm body to increase the strength and stiffness of the upper hinge arm body and the lower hinge arm body and prevent deformation during the frequent rotation of the swing door body.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: In the solution of the present application: In order to solve the problems of poor durability of the snap ring limit and serious attenuation of the limit force in the prior art, in the present application, by setting the limit lock catch and the limit lock body, the limit lock catch moves with the movement of the lower hinge arm body. When the swing door body is opened to the maximum opening degree, the limit lock catch can enter the limit lock body to realize locking and limiting. Compared with the traditional swing door snap ring limit structure, it has stronger durability, extremely small attenuation of the limit force, and extremely small destructive force on the structure generated by the normal locking of the limit lock catch and the limit lock body itself, because the strength of the limit lock catch and the limit lock body far exceeds that of the ordinary snap ring limit, and the material is also better.

[0018] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0019] It should be noted that, without conflict, the embodiments and the features and technical solutions in the embodiments of the present invention can be combined with each other.

[0020] It should be noted that similar reference numerals and letters denote similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0021] For the embodiments, please refer toFigures 1 - 8 , a door opening limit lock structure for being installed on the swing door main body 11 to achieve the limit after the swing door main body 11 is opened, including a limit lock main body 1, a limit lock mounting bracket 2, a first lower hinge arm hinge bracket 3, a limit lock catch 4 and a lower hinge arm main body 5 installed on the swing door main body 11. Specifically: The limit lock mounting bracket 2 is fixed on the swing door main body 11 as the installation basis of the limit lock main body 1, and the limit lock main body 1 is installed on the limit lock mounting bracket 2; the limit lock main body 1 cooperates with the limit lock catch 4 when the swing door main body 11 is opened to a specific position to achieve the limit; by fixing the limit lock mounting bracket 2 on the swing door main body 11, the limit lock main body 1 can be stably installed on this bracket, reducing the problem of limit failure caused by unstable installation, thus ensuring the accuracy and reliability of the limit function; The limit lock catch 4 is fixed on the lower hinge arm main body 5, and the limit lock catch 4 moves with the movement of the lower hinge arm main body 5. When the swing door main body 11 is opened to the maximum opening degree, the limit lock catch 4 can enter the limit lock main body 1 to achieve locking; it has stronger durability than the traditional swing door snap ring limit structure, and the attenuation of the limit force is extremely small. The normal locking of the limit lock catch 4 and the limit lock main body 1 itself generates extremely small destructive force on the structure because the strength of the limit lock catch 4 and the limit lock main body 1 far exceeds that of the ordinary snap ring limit, and the material is also better.

[0022] Furthermore, it also includes a second lower hinge arm hinge bracket 6. The second lower hinge arm hinge bracket 6 is combined with the lower hinge arm main body 5 through a ball hinge, enhancing the movement flexibility and stability of the lower part of the swing door main body 11, and being able to better adapt to different movement states and force conditions; the ball hinge combination method can evenly disperse the force, reduce local stress concentration, enhance the structural stability, and make the swing door main body 11 more stable during the opening and closing processes.

[0023] Furthermore, the first lower hinge arm hinge bracket 3 is fixed on the swing door main body 11, and the first lower hinge arm hinge bracket 3 is rotationally combined with the lower hinge arm main body 5 to form the support and rotation of the lower part of the swing door main body 11; the first lower hinge arm hinge bracket 3 is fixed on the swing door main body 11 and rotationally combined with the lower hinge arm main body 5 to form a stable support and rotation structure; this structure can bear the weight of the swing door main body 11 and the forces generated during the movement process, enabling the swing door main body 11 to be opened and closed smoothly.

[0024] Furthermore, when the limit lock main body 1 catches the limit lock catch 4, the limit in the X direction and Y direction of the swing door main body 11 is achieved, ensuring the stability and safety of the swing door main body 11 in the open state; when the limit lock main body 1 catches the limit lock catch 4, the movement of the swing door main body 11 in the X direction and Y direction is restricted, guaranteeing the stability and safety of the swing door main body 11 and reducing the risk of safety accidents.

[0025] Further, the limit lock mounting bracket 2 is welded to the swing door main body 11.

[0026] Further, it further includes an upper limit portion. The limit portion is arranged on the swing door main body 11 and includes a first upper hinge arm limit hinge bracket 7, an upper hinge arm main body 8, a second upper hinge arm limit hinge bracket 9 and a limit boss 10.

[0027] Further, both ends of the upper hinge arm main body 8 are rotatably connected to the first upper hinge arm limit hinge bracket 7 and the second upper hinge arm limit hinge bracket 9 respectively to form an upper support and rotation structure of the swing door main body 11; the rotational connection of the upper hinge arm main body 8 with the first upper hinge arm limit hinge bracket 7 and the second upper hinge arm limit hinge bracket 9 forms a stable upper support and rotation structure, which can bear the weight of the upper part of the swing door main body 11 and the forces generated during the movement process, making the swing door main body 11 more stable during the opening and closing processes.

[0028] Further, the first upper hinge arm limit hinge bracket 7 is connected to the swing door main body 11 by bolts; the bolt installation method is simple and convenient to operate, and no complex tools and processes are required.

[0029] Further, the limit boss 10 is arranged on the upper hinge arm main body 8, and a limit groove 701 is arranged on the first upper hinge arm limit hinge bracket 7. The limit boss 10 is inserted and matched with the limit groove 701 when the swing door main body 11 is opened to the maximum opening degree to realize the Z-direction limit of the swing door main body 11; it can prevent the swing door main body 11 from undergoing excessive displacement in the Z direction due to gravity or other factors in the open state, thus ensuring the stability and safety of the swing door main body 11 and reducing collisions or other problems caused by the movement of the swing door main body 11 in the Z direction.

[0030] Further, reinforcing ribs are arranged inside both the upper hinge arm main body 8 and the lower hinge arm main body 5. The reinforcing ribs extend along the length direction or width direction of the upper hinge arm main body 8 and the lower hinge arm main body 5 to increase the strength and stiffness of the upper hinge arm main body 8 and the lower hinge arm main body 5 and prevent deformation during the frequent rotation of the swing door main body 11; the arrangement of the reinforcing ribs can effectively increase the strength and stiffness of the upper hinge arm main body 8 and the lower hinge arm main body 5. During the rotation of the swing door main body 11, the upper hinge arm main body 8 and the lower hinge arm main body 5 will bear greater forces and stresses. The reinforcing ribs can disperse these forces and stresses, reduce local deformation, ensure the structural stability of the upper hinge arm main body 8 and the lower hinge arm main body 5, and extend their service life.

[0031] The usage process of the door opening limit lock structure provided by the present invention is as follows: When the swing door main body 11 is opened, the limit lock catch 4 on the lower hinge arm main body 5 enters the limit lock main body 1. After entering the locked state, since the limit lock catch 4 is locked by the locking tongue of the limit lock main body 1, the swing door main body 11 cannot move outwards in the Y direction of the vehicle. At the same time, because the movement path of the swing door main body 11 is a simultaneous movement in the X and Y directions, while the Y direction is restricted, the swing door main body 11 cannot move in the X direction either; At the same time when the lower limit lock catch 4 and the limit lock main body 1 are locked, the limit boss 10 enters the limit groove 701 and is limited. While the swing door main body 11 is restricted from moving in the X and Y directions, due to the insertion of the limit boss 10 and the limit groove 701, a large displacement of the swing door main body 11 in the Z direction cannot occur either; Because the hinge force arm of the swing door main body 11 is longer than that of the traditional sliding door, when the swing door main body 11 is in the open state, if only the lower hinge arm main body 5 and the upper hinge arm main body 8 are used to support the swing door main body 11, when an external force acts on the rear edge of the swing door main body 11, rotational displacement is likely to occur, that is, there will be a displacement downward in the Z direction at the rear of the swing door main body 11. However, due to the cooperation of the limit boss 10 and the limit groove 701 provided in this application, stable support is provided.
