[0030] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are some but not all of the embodiments of this application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in this application without creative efforts belong to the scope of protection of this application.
[0031] In view of the deficiencies or one of the deficiencies proposed in the above background art, the embodiments of this application provide a flexible and steplessly adjustable cable device and an automobile, which can freely adapt to the effective length stroke, be adjusted multiple times, have high reliability, and are not easily damaged due to failure.
[0032] See Figures 1 to 4 As shown, in the first aspect of the embodiments of this application, a flexible and steplessly adjustable cable device is provided, including:
[0033] A cable joint 1, on the outer wall of which a first tooth row 11 is provided;
[0034] An adjustment housing 2, on which an adjustment slot 21 for inserting the cable joint 1 is provided, and an elastic clamping plate 22 is arranged in the adjustment slot 21. A second tooth row 23 meshing with the first tooth row 11 is provided on the elastic clamping plate 22;
[0035] A constraint member 3, which is arranged on the adjustment housing 2 and is used to constrain the elastic clamping plate 22 to fasten the second tooth row 23 on the first tooth row 11.
[0036] On the outer wall of the cable joint 1 of the cable device in the embodiments of this application, a first tooth row 11 is provided. At the same time, an elastic clamping plate 22 is arranged in the adjustment slot 21 of the adjustment housing 2 for inserting the cable joint 1, and a second tooth row 23 that can mesh with the first tooth row 11 is provided on the elastic clamping plate 22. Since the elastic clamping plate 22 has elasticity, when the cable joint 1 is inserted into the adjustment slot 21 of the adjustment housing 2, the cable joint 1 can squeeze the first tooth row 11 on the elastic clamping plate 22, causing the elastic clamping plate 22 to bend and deform toward the side away from the cable joint 1, so as to facilitate the insertion of the cable joint 1 to a suitable position inside the adjustment housing 2.
[0037] The elastic clamping plate 22 resumes its deformation, ensuring the engagement of the first tooth row 11 on the cable joint 1 with the second tooth row 23 on the elastic clamping plate 22. To ensure the installation and use effect and prevent the first tooth row 11 on the cable joint 1 from disengaging from the second tooth row 23 on the elastic clamping plate 22, a constraint component 3 is also provided. The constraint component 3 can be installed on the adjustment housing 2 to restrict the elastic clamping plate 22 from bending and deforming away from the cable joint 1 side. That is, after the first tooth row 11 on the cable joint 1 is engaged with the second tooth row 23 on the elastic clamping plate 22, the constraint component 3 is installed to prevent the elastic clamping plate 22 from deforming, so that the second tooth row 23 on the elastic clamping plate 22 is fastened to the first tooth row 11 on the cable joint 1.
[0038] When it is necessary to re-adjust the length of the cable joint 1 inserted into the adjustment housing 2, the constraint component 3 can be disassembled to adjust the relative position of the cable joint 1 and the adjustment housing 2. Since the elastic clamping plate 22 loses the constraint of the constraint component 3, under the extrusion of the first tooth row 11 on the cable joint 1, the elastic clamping plate 22 bends and deforms away from the cable joint 1 side, thus facilitating the adjustment of the position of the cable joint 1 inserted into the adjustment housing 2. After the cable joint 1 adjusts its position again, the constraint component 3 is reinstalled, and the second tooth row 23 on the elastic clamping plate 22 can be fastened to the first tooth row 11 on the cable joint 1. Thus, it can achieve free adaptation of the effective length stroke, and can be adjusted multiple times. Compared with threaded connection, it is not easy to fail and damage, and has high reliability.
[0039] Exemplarily, the first tooth row 11 on the cable joint 1 includes a plurality of convex teeth arranged along its length direction. The two sides of the convex teeth in the direction of inserting into the adjustment housing 2 are both inclined planes, which is convenient for extruding the second tooth row 23 on the elastic clamping plate 22 when inserting into the adjustment housing 2. The second tooth row 23 on the elastic clamping plate 22 includes a plurality of tooth grooves arranged along its length direction. The tooth grooves are adapted to the convex teeth. The constraint component 3 is a plate member that is not easy to deform and can be installed on the adjustment housing 2 by means of insertion or fastening to abut against the side of the elastic clamping plate 22 away from the cable joint 1, protecting the elastic clamping plate 22 from deforming and playing a role in fastening the second tooth row 23 to the first tooth row 11.
[0040] That is, the present application designs a new cable device, which can be flexibly and steplessly adjusted, can freely adapt the effective length stroke, can be adjusted multiple times, and does not cause damage to the part product body of the secondary cable and wire drawing. The accuracy of adapting the effective length stroke is high, which can be accurate to the millimeter level to better meet the requirements of the high-precision effective length stroke of the lock body.
[0041] The cable device of the present application can freely and accurately adjust the effective length stroke, and the operation can be completed manually without using tools. The relative positions of the cable joint 1 and the adjustment housing 2 of the present application at the time of leaving the factory can be preset according to the design value. If there is no deviation during assembly with the lock body, there is no need to adapt and adjust the effective length stroke, thereby improving the production beat.
[0042] In a first aspect, in some alternative embodiments: Refer to Figures 1 to 4 As shown, the embodiment of the present application provides a flexible and steplessly adjustable cable device. Both ends of the elastic clamping plate 22 of the flexible and steplessly adjustable cable device along the insertion direction of the cable joint 1 are fixedly connected or integrally formed with the adjustment housing 2, and the first tooth row 11 squeezes the second tooth row 23 to cause the elastic clamping plate 22 to deflect and deform in a direction away from the first tooth row 11.
[0043] Both ends of the elastic clamping plate 22 of the cable device in the embodiment of the present application along the insertion direction of the cable joint 1 are fixedly connected or integrally formed with the adjustment housing 2, and the first tooth row 11 squeezes the second tooth row 23 to cause the elastic clamping plate 22 to deflect and deform in a direction away from the first tooth row 11, thereby facilitating the adjustment of the length of the cable joint 1 inserted into the adjustment housing 2.
[0044] That is, the present application cleverly uses the elastic deformation of the elastic clamping plate 22 to cooperate with the cable joint 1 to adjust the length inserted into the adjustment housing 2. Since both ends of the elastic clamping plate 22 are fixed to the adjustment housing 2, when the first tooth row 11 on the cable joint 1 squeezes the second tooth row 23 on the elastic clamping plate 22 along the insertion direction, the middle part of the elastic clamping plate 22 can bend and deform in a direction away from the cable joint 1 side, thereby facilitating the first tooth row 11 on the cable joint 1 to slide and engage with the second tooth row 23 at a suitable position.
[0045] Exemplarily, the elastic clamping plate 22 can be integrally injection-molded with the adjustment housing 2, and the property that the plastic material itself can deform slightly is used to meet the installation of the cable joint 1. Compared with the implementation method of threaded connection in the related art, the processing accuracy requirements are relatively low and the processing difficulty is small. In other embodiments, the elastic clamping plate 22 and the adjustment housing 2 can be separately provided and made of different materials. According to the material properties, the elastic clamping plate 22 can be fixed to the adjustment housing 2 by means of clamping, welding, hot melting or fastener connection, etc.
[0046] In addition, it should be noted that in this embodiment, in order to facilitate the first tooth row 11 to squeeze the second tooth row 23 to cause the elastic clamping plate 22 to deflect and deform in a direction away from the first tooth row 11. The convex teeth on the cable joint 1 are both inclined planes on both sides in the insertion direction of the adjustment housing 2, which facilitates squeezing the second tooth row 23 on the elastic clamping plate 22 when inserting the adjustment housing 2.
[0047] The tooth grooves on the elastic clamping plate 22 are adapted to the convex teeth. The restraining member 3 is a plate member that is not easily deformed and can be installed on the adjusting housing 2 by means of inserting sleeves or fasteners, so as to abut against the side of the elastic clamping plate 22 away from the cable joint 1, prevent the elastic clamping plate 22 from deforming, and play a role in fastening the second tooth row 23 to the first tooth row 11.
[0048] In a first aspect, in some alternative embodiments: Refer to Figures 1 to 4 As shown, the embodiment of the present application provides a flexible and steplessly adjustable cable device. The elastic clamping plate 22 of the flexible and steplessly adjustable cable device includes a middle part and two end parts. The thickness of the two end parts of the elastic clamping plate 22 is less than the thickness of the middle part. The second tooth row 23 includes a plurality of tooth grooves provided on the middle part of the elastic clamping plate 22.
[0049] The elastic clamping plate 22 of the cable device in the embodiment of the present application includes a middle part and two end parts. The thickness of the two end parts of the elastic clamping plate 22 is less than the thickness of the middle part. The tooth grooves of the second tooth row 23 are formed on the middle part of the second tooth row 23 and are arranged along the length direction of the elastic clamping plate 22. Since no tooth grooves are provided on the two end parts of the elastic clamping plate 22, when the middle part of the elastic clamping plate 22 is squeezed, it is more likely to bend and deform, which is convenient for the cable joint 1 to be inserted and squeeze the elastic clamping plate 22.
[0050] It should be noted that when the first tooth row 11 squeezes the second tooth row 23 to cause the elastic clamping plate 22 to flex and deform in a direction away from the first tooth row 11, since the two end parts of the elastic clamping plate 22 are fixed or integrally connected to the adjusting housing 2, the two end parts of the elastic clamping plate 22 are not easily flexed and deformed and the bending amplitude is limited. To facilitate the smooth insertion of the cable joint 1, the thickness of the two end parts of the elastic clamping plate 22 is less than the thickness of the middle part, that is, the two end parts of the elastic clamping plate 22 are thinned relative to the middle part, so that it is more likely to bend and deform, which is convenient for the cable joint ! to be inserted and squeeze the elastic clamping plate 22.
[0051] Exemplarily, in the insertion direction of the cable joint 1, the second tooth row 23 does not extend to the two ends of the elastic clamping plate 22. When the first tooth row 11 squeezes the second tooth row 23, the two ends of the elastic clamping plate 22 are bent and deformed, and the shear force received is small. In addition, the second tooth row 23 includes a plurality of tooth grooves formed on the middle part of the elastic clamping plate 22. The tooth grooves are composed of two inclined surfaces to adapt to the convex teeth on the cable joint 1, which is convenient for the convex teeth on the cable joint 1 to slide into or out of the tooth grooves along the inclined surfaces of the tooth grooves. The groove width of the tooth grooves can be set within one millimeter, which is convenient for the cable joint 1 to adjust the length inserted into the adjusting housing 2 and realize the stroke adjustment at the millimeter level.
[0052] In a first aspect, in some alternative embodiments: Refer to Figures 1 to 4As shown in the figure, an embodiment of the present application provides a flexible and steplessly adjustable cable device. An elastic deformation space for the elastic clamping plate 22 to flexibly deform is provided on the side of the elastic clamping plate 22 of the flexible and steplessly adjustable cable device away from the second tooth row 23. The constraint member 3 is detachably installed in the elastic deformation space to prevent the elastic clamping plate 22 from flexibly deforming.
[0053] An elastic deformation space for the elastic clamping plate 22 to flexibly deform is provided on the side of the elastic clamping plate 22 of the cable device in the embodiment of the present application away from the second tooth row 23. When the cable joint 1 is inserted into the adjustment housing 2, the elastic deformation space can satisfy the convex deformation of the elastic clamping plate 22 toward the side away from the cable joint 1. Furthermore, in the way of flexural deformation, the second tooth row 23 can avoid the first tooth row 11, facilitating the sliding and clamping of the first tooth row 11 along the second tooth row 23 to a proper position.
[0054] In addition, the constraint member 3 is detachably installed in the elastic deformation space. Since the constraint member 3 is not easily deformed, when the constraint member 3 occupies the elastic deformation space, there is no space for the elastic clamping plate 22 to flex outward. Therefore, by constraining the elastic clamping plate 22, the constraint member 3 can fasten the second tooth row 23 on the elastic clamping plate 22 to the first tooth row 11 of the cable joint 1. The detachable nature of the constraint member 3 facilitates adjusting the length of the cable joint 1 inserted into the adjustment housing 2 at any time. That is, when it is necessary to adjust the relative position of the cable joint 1 and the adjustment housing 2, the constraint member 3 can be removed. After adjusting the position of the cable joint 1 relative to the adjustment housing 2, the constraint member 3 is reinstalled and reset.
[0055] Exemplarily, the elastic clamping plate 22 can serve as a part of the adjustment housing 2 and directly act as the outer wall of the adjustment housing 2, enabling unrestricted outward bending deformation of the elastic clamping plate 22. The constraint member 3 can be an outer frame sleeved on the housing. The outer frame is made of a metal material that is not easily deformed. The outer frame can be installed on the adjustment housing 2 by means of clamping or fastener connection. The outer frame covers the elastic clamping plate 22 and abuts against the outer wall surface of the elastic clamping plate 22, thereby restricting the outward bending deformation of the elastic clamping plate 22. It should be noted that after installation, the elastic clamping plate 22 is located on the periphery of the cable joint 1. Therefore, the constraint member 3 can prevent the cable joint 1 from detaching from the elastic clamping plate 22 by constraining the elastic clamping plate 22.
[0056] In a first aspect, in some alternative embodiments: Refer to Figures 1 to 4 As shown in the figure, an embodiment of the present application provides a flexible and steplessly adjustable cable device. A card slot 4 forming an elastic deformation space is provided between the elastic clamping plate 22 and the adjustment housing 2 of the flexible and steplessly adjustable cable device. The width dimension of the card slot 4 is not less than the tooth height of the first tooth row 11, and the constraint member 3 is a card block adapted to the card slot 4.
[0057] A clamping groove 4 forming an elastic deformation space is provided between the elastic clamping plate 22 of the cable device in the embodiment of the present application and the adjusting housing 2. When the cable joint 1 is inserted into the adjusting housing 2, the clamping groove 4 can satisfy the elastic clamping plate 22 to bulge and deform away from the cable joint 1 side. Furthermore, in a flexural deformation manner, the second tooth row 23 can avoid the first tooth row 11, facilitating the first tooth row 11 to slide and engage along the second tooth row 23 to a proper position.
[0058] Furthermore, the width dimension of the clamping groove 4 is not less than the tooth height of the first tooth row 11. When the cable joint 1 is inserted into the adjusting housing 2, under the extrusion of the cable joint 1, the elastic clamping plate 22 bends and deforms away from the cable joint 1 side and contacts the adjusting housing 2. Since the dimension of the clamping groove 4 is not less than the tooth height of the first tooth row 11, therefore, a space can be provided for the first tooth row 11 on the cable joint 1 to slide and engage, facilitating the cable joint 1 to slide and engage to any position on the elastic clamping plate 22.
[0059] It should be noted that the width dimension of the clamping groove 4 is the distance from the side of the elastic clamping plate 22 away from the cable joint 1 to the adjusting housing 2. If the width dimension of the clamping groove 4 is less than the tooth height of the first tooth row 11, it will cause that after the elastic clamping plate 22 bends and deforms away from the cable joint 1 side, no space can be provided for the cable joint 1 to slide to adjust the position. Therefore, the width dimension of the clamping groove 4 is not less than the tooth height of the first tooth row 11, which does not affect the cable joint 1 to slide and engage into the adjusting housing 2. At the same time, the clamping groove 4 can also limit the amplitude of the elastic clamping plate 22 bending outward, avoiding the elastic clamping plate 22 from bending outward excessively, and playing a role in protecting the elastic clamping plate 22 to a certain extent.
[0060] In addition, the clamping groove 4 in this embodiment can be used for installing the restraining component 3. For example, the restraining component 3 in this embodiment is a block adapted to the clamping groove 4. The block can be inserted into the clamping groove 4. By occupying the space in the clamping groove 4, the elastic clamping plate 22 is restrained, avoiding the elastic clamping plate 22 from elastically deforming outward, and thus realizing fastening the elastic clamping plate 22 on the cable joint 1.
[0061] First aspect, in some alternative embodiments: Refer to Figures 1 to 4 As shown, the embodiment of the present application provides a flexible cable device with stepless adjustment. An opening 5 exposing the second tooth row 23 is provided on the adjusting housing 2 of the flexible cable device with stepless adjustment. When the cable joint 1 is inserted into the adjusting housing 2, the meshing part of the first tooth row 11 and the second tooth row 23 is exposed from the opening 5.
[0062] An opening 5 exposing the second tooth row 23 is provided on the adjusting housing 2 of the cable device according to the embodiment of the present application. When the cable joint 1 is inserted into the adjusting housing 2, the opening 5 can expose the meshing portion of the first tooth row 11 and the second tooth row 23, so as to facilitate observing the position where the cable joint 1 is inserted into the adjusting housing 2 and whether the first tooth row 11 and the second tooth row 23 are meshed in place. To a certain extent, the installation convenience is improved, which is convenient for workers to operate and install.
[0063] Exemplarily, the opening 5 of this embodiment is provided on the side wall of the adjusting housing 2. The opening 5 is directly surrounded by the elastic clamping plate 22 and the adjusting housing 2. The opening 5 communicates with the notch of the adjusting groove 21 at the end of the adjusting housing 2. When the cable joint 1 is inserted into the adjusting housing 2 along the adjusting groove 21, the first tooth row 11 on the cable joint 1 can be seen from the opening 5 on the side wall of the adjusting housing 2. Furthermore, the meshing condition of the first tooth row 11 and the second tooth row 23, as well as whether the elastic clamping plate 22 is in normal use or fails, can be directly observed through the opening 5.
[0064] That is, an opening 5 exposing the second tooth row 23 is provided on the adjusting housing 2, which is convenient for checking whether the cable joint 1 is installed in place after being inserted into the adjusting housing 2, and reduces the manufacturing difficulty of the adjusting housing 2. The elastic clamping plate 22 is a part of the adjusting housing 2. Coupled with the opening 5 being provided on the side wall of the adjusting housing 2, the manufacturing material of the adjusting housing 2 can be reduced, which is convenient for integral injection molding.
[0065] In addition, the opening 5 is provided on the side wall of the adjusting housing 2 and can be covered by the restraining member 3. For example, in this embodiment, the restraining member 3 is a U-shaped block. After the U-shaped block is inserted into the card slot 4 outside the elastic clamping plate 22, while occupying the card slot 4 and restricting the elastic clamping plate 22 from bending and deforming outward, the opening 5 on the side wall of the adjusting housing 2 can be covered, thereby preventing foreign objects such as particles from entering the adjusting groove 21 and affecting the normal meshing of the first tooth row 11 on the cable joint 1 and the second tooth row 23 on the elastic clamping plate 22.
[0066] First aspect, in some alternative embodiments: Refer to Figures 1 to 4 As shown, the embodiment of the present application provides a flexible cable device with stepless adjustment. The number of elastic clamping plates 22 of the flexible cable device with stepless adjustment is two and they are symmetrically arranged on both sides of the cable joint 1. The restraining member 3 is a U-shaped block, and the U-shaped block is inserted on the adjusting housing 2 and abuts against the opposite sides of the two elastic clamping plates 22.
[0067] The number of elastic clamping plates 22 of the cable device in the embodiment of the present application is two, and they are symmetrically arranged on both sides of the cable joint 1. After the cable joint 1 is inserted and installed into the adjusting housing 2, the elastic clamping plates 22 abut against both sides of the cable joint 1. After cooperating with the installation constraining member 3, the position of the cable joint 1 can be stably restricted. Compared with setting the elastic clamping plate 22 on one side only, setting the elastic clamping plates 22 on both sides simultaneously can improve the use stability of the cable joint 1, making it difficult for the cable joint 1 to break out of the adjusting housing 2.
[0068] Furthermore, in this embodiment, the constraining member 3 is a U-shaped block, which is inserted into the adjusting housing 2 and abuts against the opposite sides of the two elastic clamping plates 22. That is, when the U-shaped block is installed, it can just be inserted into the two clamping slots 4 on the opposite sides of the two elastic clamping plates 22 and occupy the space in the clamping slots 4. At the same time, it can cover the opening 5 on the side wall of the adjusting housing 2, thereby preventing foreign objects such as particles from entering the adjusting slot 21. The U-shaped block is made of a material that is not easily deformed and abuts against the opposite sides of the two elastic clamping plates 22, which can effectively prevent the two elastic clamping plates 22 from bending and deforming outward, and realize fastening the second tooth row 23 on the first tooth row 11.
[0069] It should be noted that an opening 5 is provided on the side wall of the adjusting housing 2 in this embodiment. The side of the adjusting housing 2 far away from the opening 5 is closed, that is, the side of the adjusting housing 2 far away from the opening 5 has a bottom wall that forms the wall surface of the adjusting slot 21, and the bottom wall is not connected to the elastic clamping plate 22, thus not restricting the outward bending deformation of the two elastic clamping plates 22. In some other embodiments, the side of the adjusting housing 2 far away from the opening 5 can also be directly designed as an open mouth, so as to facilitate observing the connection situation of the cable joint 1 and the elastic clamping plate 22 from both sides, which can further improve the installation convenience.
