Description

Technical Field

[0001] The present application relates to the technical field of automobile accessories, and in particular to a positioning structure and a connection kit for a reversing pulley. Background Art

[0002] The current automobile door usually includes an outer sheet metal plate constituting the outer skin of the door and an inner sheet metal plate connected to the outer sheet metal plate. In order to meet the lightweight requirements, the middle part of the inner sheet metal plate is set as a fully plastic molded carrier plate, and the door functional components such as the window glass lifter and the side airbag module are pre-installed on the carrier plate. Finally, these door functional components and the carrier plate together form an integrated door module to realize the assembly of the door functional components on the door. Usually, the window glass lifter includes a wire rope and a reversing pulley. The wire rope is clamped in the groove of the reversing pulley. The wire rope is used for transmission, and the reversing pulley is used to adjust the direction of the wire rope. The conventional design is to fix the reversing pulley on the carrier plate using a metal shaft pin and a metal gasket. During the process, a riveting process is required. This fixing method of the reversing pulley is relatively cumbersome and is not conducive to the realization of the lightweight goal. In addition, it is difficult to set an oil storage structure on the surface of the metal shaft pin, which is not conducive to reducing the friction between the shaft pin and the pulley and reducing noise. In addition, in order to extend the service life of the metal shaft pin, the surface of the metal shaft pin needs to be treated with anti-corrosion. Utility Model Content

[0003] In order to solve the above problems, the present application provides a positioning structure and a connection kit for a reversing pulley, which are cleverly designed and simple in structure. The present application simplifies the positioning structure of the reversing pulley. The positioning structure can facilitate the installation of the reversing pulley and improve the installation efficiency of the reversing pulley. At the same time, the positioning structure is made by an integrated molding process, which saves the installation procedure of parts and components and improves the assembly efficiency of the integrated door module. The technical solutions adopted in the present application are as follows:

[0004] A positioning structure for a reversing pulley, comprising:

[0005] A connecting plate, a column part, an extension part, an elastic part and a hook part; the column part is connected to one side of the connecting plate; the extension part extends from the column surface of the column part in a direction away from the column part, and the extension part, the column part and the connecting plate together form a first clamping space; the elastic part is connected to one side of the connecting plate and is located on the side of the column part away from the extension part; the hook part is connected to the side of the elastic part away from the column part, and the hook part, the elastic part and the connecting plate together form a second clamping space, and the first clamping space and the second clamping space are suitable for jointly clamping the reversing pulley; the positioning structure is made by an integrated molding process.

[0006] By adopting this positioning structure, the installation of the reversing pulley can be facilitated and the installation efficiency of the reversing pulley can be improved. At the same time, this positioning structure is made by an integrated molding process, which reduces the number of parts used, saves the production and procurement costs of parts and installation procedures, and thus improves the assembly efficiency of the integrated door module.

[0007] In some embodiments, the hook portion is provided with a guide surface.

[0008] By providing the guide surface, the inner hole wall of the reversing pulley can be advantageously used to squeeze the hook portion, thereby driving the elastic portion to bend and deform toward the direction close to the column portion, so that the reversing pulley is clamped into the second clamping space.

[0009] In some embodiments, a first oil storage structure is provided on a cylindrical surface of the column portion away from the elastic portion.

[0010] By providing the first oil storage structure, the friction between the reversing pulley and the column portion can be reduced, the smoothness of the rotation of the reversing pulley is improved, and the noise during the rotation of the reversing pulley is reduced.

[0011] In some embodiments, the first oil storage structure is a first strip-shaped groove, and the first strip-shaped groove extends along the height direction of the column portion.

[0012] By designing the first oil storage structure as a first strip groove structure, it is convenient for mold opening and demolding of the positioning structure. At the same time, the first strip groove extends along the height direction of the column part, which helps to disperse the lubricant in the first strip groove and ensure the lubrication effect.

[0013] In some embodiments, the column portion is a hollow structure.

[0014] By setting the column part as a hollow structure, it is helpful to control the injection molding quality of the positioning structure, and it is also possible to reduce the amount of material used, which is conducive to lightweighting of the component.

[0015] In some embodiments, a side of the column portion close to the elastic portion is provided with a clearance gap, and the clearance gap can provide a deformation space for the elastic portion.

[0016] By providing the clearance gap, deformation space can be provided for the elastic part while further reducing the weight of the component.

[0017] On the other hand, the present application provides a connection kit, comprising the aforementioned positioning structure and a reversing pulley, wherein the reversing pulley is suitable for being clamped in the positioning structure.

[0018] In some embodiments, a second oil storage structure is provided on the hole wall of the reversing pulley.

[0019] By providing the second oil storage structure, the friction between the reversing pulley and the column portion can be reduced, the smoothness of the rotation of the reversing pulley is improved, and the noise during the rotation of the reversing pulley is reduced.

[0020] In some embodiments, the second oil storage structure is a second strip groove, which extends along the thickness direction of the reversing pulley. A shielding portion is provided at one end of the second strip groove away from the connecting plate, and the shielding portion is used to prevent rainwater from entering the second strip groove.

[0021] By designing the second oil storage structure as a second strip groove structure, it is convenient to open and demould the reversing pulley, and the second strip groove extends along the thickness direction of the reversing pulley, which helps to disperse the lubricant in the second strip groove and ensure the lubrication effect. In addition, by setting a shielding portion, the end of the second strip groove away from the connecting plate can be shielded, so that water can be prevented from entering the second strip groove from the side of the reversing pulley away from the connecting plate, thereby preventing the water flow from affecting the lubrication effect and causing corrosion to other parts.

[0022] In some embodiments, an oil storage pit is provided on a side of the reversing pulley close to the connecting plate, and the oil storage pits are arranged at intervals along the circumference of the inner hole of the reversing pulley.

[0023] By providing an oil storage pit, the friction between the adjacent surfaces of the reversing pulley and the connecting plate can be reduced, and the noise (abnormal sound) when the reversing pulley rotates can be reduced.

[0024] The present application provides a positioning structure and a connection kit for a reversing pulley, which has at least one of the following beneficial effects:

[0026] 2. The present application provides a positioning structure for a reversing pulley, which, by setting a guide surface, can facilitate the inner hole wall of the reversing pulley to squeeze the hook portion, thereby driving the elastic portion to bend and deform in a direction close to the column portion, so that the reversing pulley is stuck in the second clamping space.

[0027] 3. The present application provides a positioning structure for a reversing pulley, which can reduce the friction between the reversing pulley and the column part by setting a first oil storage structure, thereby improving the smoothness of the rotation of the reversing pulley and reducing the noise during the rotation of the reversing pulley.

DETAILED DESCRIPTION

[0045] In order to more clearly illustrate the embodiments of the present application or the technical solutions in the prior art, the specific implementation methods of the present application will be described below with reference to the accompanying drawings. Obviously, the drawings described below are only some embodiments of the present application. For ordinary technicians in this field, other drawings and other implementation methods can be obtained based on these drawings without creative work.

[0046] In order to simplify the drawings, only the parts related to the present application are schematically shown in each figure, and they do not represent the actual structure of the product. In addition, in order to simplify the drawings and facilitate understanding, in some figures, only one of the parts with the same structure or function is schematically drawn or marked. In this article, "one" not only means "only one", but also means "more than one".

[0047] It should be further understood that the term “and / or” used in the specification and appended claims refers to any combination and all possible combinations of one or more of the associated listed items, and includes these combinations.

[0048] In this document, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0049] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0050] refer to Figure 1-Figure 7 The present application provides a positioning structure for a reversing pulley, comprising: a connecting plate 1, a column portion 2, an extension portion 3, an elastic portion 4 and a hook portion 5; the column portion 2 is connected to one side of the connecting plate 1; the extension portion 3 extends from the column surface of the column portion 2 in a direction away from the column portion 2, and the extension portion 3, the column portion 2 and the connecting plate 1 together form a first clamping space 13; the elastic portion 4 is connected to one side of the connecting plate 1 and is located on the side of the column portion 2 away from the extension portion 3; the hook portion 5 is connected to the side of the elastic portion 4 away from the column portion 2, and the hook portion 5, the elastic portion 4 and the connecting plate 1 together form a second clamping space 14, and the first clamping space 13 and the second clamping space 14 are suitable for clamping the reversing pulley 12 together; the positioning structure is made by an integrated molding process.

[0051] Specifically, the connecting plate 1 may refer to a carrier plate on which functional door components such as a window glass lifter and a side airbag module can be pre-installed, or it may be a component that can be mounted on the carrier plate. The positioning structure is introduced below in the state where the reversing pulley 12 has been installed on the positioning structure and the wire rope has been installed on the reversing pulley 12: It can be understood that only a portion of the reversing pulley 12 is in contact with the wire rope in the circumferential direction, and the extension portion 3 is located on the side of the column portion 2 close to the portion of the reversing pulley 12 that contacts the wire rope, that is, the extension portion 3 is located on the side of the column portion 2 away from the direction of the combined force of the wire rope. Reference Figure 4-Figure 7 The installation process of the reversing pulley 12 is as follows: the reversing pulley 12 is first hooked near the first clamping space 13, and then the elastic part 4 is deformed, and then the reversing pulley 12 is pressed into the first clamping space 13 and the second clamping space 14, so that the installation of the reversing pulley 12 is completed. It can be understood that after the reversing pulley 12 is installed, the extension part 3 and the hook part 5 are both located on the side of the reversing pulley 12 away from the connecting plate 1, and the extension part 3 and the hook part 5 both restrict the reversing pulley 12 from moving in the direction away from the connecting plate 1, that is, the extension part 3 and the hook part 5 can prevent the reversing pulley 12 from detaching from the column part 2.

[0052] It can be understood that the use of this positioning structure can facilitate the installation of the reversing pulley 12 and improve the installation efficiency of the reversing pulley 12. At the same time, this positioning structure is made by an integrated molding process, which reduces the number of parts used and saves the production and procurement costs of parts and installation procedures, thereby improving the assembly efficiency of the integrated door module.

[0053] It is worth noting that reference Figure 1-Figure 7 In one embodiment, the hook portion 5 is provided with a guide surface 6. By providing the guide surface 6, the inner hole wall of the reversing pulley 12 can be advantageously pressed against the hook portion 5, thereby driving the elastic portion 4 to bend and deform in a direction close to the column portion 2, so that the reversing pulley 12 is clamped into the second clamping space 14. In other embodiments, the hook portion 5 may not be provided with a guide surface 6, and the deformation of the elastic portion 4 is achieved by an auxiliary tool. It can be understood that the auxiliary tool only needs to be able to bend the elastic portion 4 in a direction close to the column portion 2.

[0054] It is easy to understand that in order to reduce the friction between the reversing pulley 12 and the column part 2, improve the smoothness of the rotation of the reversing pulley 12, and reduce the noise when the reversing pulley 12 rotates, a first oil storage structure can be provided on the cylindrical surface of the column part 2 away from the elastic part 4. The first oil storage structure can be dispersed oil storage pits or oil storage grooves, such as Figure 1 , Figure 2 The first strip groove 7 shown in the figure extends along the height direction of the column part 2. Obviously, by designing the first oil storage structure as the structural form of the first strip groove 7, it is convenient to open and demould the positioning structure, and at the same time, the first strip groove 7 extends along the height direction of the column part 2, which helps to disperse the lubricant in the first strip groove 7 and ensure the lubrication effect.

[0055] It is understandable that the column portion 2 may be a solid structure or may be a Figure 1-Figure 7 The hollow structure shown can also be a hollow structure, preferably a hollow structure. Setting the column part 2 as a hollow structure can help control the injection molding quality of the positioning structure, while also reducing material usage and helping to achieve lightweight components.

[0056] refer to Figure 1-Figure 3 In one embodiment, a clearance notch 8 is provided on one side of the column portion 2 close to the elastic portion 4. By providing the clearance notch 8, deformation space can be provided for the elastic portion 4 while further reducing the weight of the component.

[0057] refer to Figure 5-Figure 7The present application also provides a connection kit, including the aforementioned positioning structure and a reversing pulley 12, wherein the reversing pulley 12 is adapted to be clamped in the positioning structure. The specific structure of the positioning structure refers to the aforementioned embodiment. Since the present connection kit adopts the technical solution of the aforementioned embodiment, it at least has the beneficial effects brought by the technical solution of the aforementioned embodiment, which will not be described one by one here.

[0058] It can be understood that in order to reduce the friction between the reversing pulley 12 and the column part 2, improve the smoothness of the rotation of the reversing pulley 12, and reduce the noise when the reversing pulley 12 rotates, a second oil storage structure can be provided on the hole wall of the reversing pulley 12. The second oil storage structure can be dispersed oil storage pits or oil storage grooves, such as Figure 8 The second strip groove 9 shown in the figure extends along the thickness direction of the reversing pulley 12. Obviously, by designing the second oil storage structure as the structural form of the second strip groove 9, it is convenient to open the mold and demould the reversing pulley 12. At the same time, the second strip groove 9 extends along the thickness direction of the reversing pulley 12, which helps to disperse the lubricant in the second strip groove 9 and ensure the lubrication effect.

[0059] It is worth noting that, in order to prevent rainwater from entering the second strip groove 9, a shielding portion 10 may be provided at one end of the second strip groove 9 away from the connecting plate 1. Figure 8 By setting the shielding portion 10, the end of the second strip groove 9 away from the connecting plate 1 can be shielded, so that water can be prevented from entering the second strip groove 9 from the side of the reversing pulley 12 away from the connecting plate 1, thereby preventing the water flow from affecting the lubrication effect and causing corrosion to other parts. The water flow may be rainwater or car washing water when washing a car. Because the car washing water contains detergent, it is even more necessary to prevent it.

[0060] It is easy to understand that in one embodiment, a third oil storage structure is provided on one side of the reversing pulley 12 close to the connecting plate 1. The third oil storage structure can be an oil storage groove or a Figure 8 The oil storage pits 11 shown are arranged at intervals along the circumference of the inner hole of the reversing pulley 12. By setting a third oil storage structure, the friction between the adjacent surfaces of the reversing pulley 12 and the connecting plate 1 can be reduced, and the noise (abnormal sound) when the reversing pulley 12 rotates can be weakened.

[0061] It should be noted that the above embodiments can be freely combined as needed. The above are only preferred implementations of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present application, and these improvements and modifications should also be regarded as the protection scope of the present application.
