Description

Technical Field

[0001] This disclosure relates to the field of automotive door lock technology, and more particularly to an inward-opening pull-wire structure, an automotive side door lock, a car door, and a vehicle. Background Technology

[0002] The inward-opening cable is a common component of automotive side door locks. Specifically, the inward-opening cable is located on the outer side of the lock body linkage along the width of the vehicle and is connected to the inward-opening linkage located below the lock body linkage to achieve the locking or unlocking of the door.

[0003] During specific assembly, refer to Figure 1 As shown, the inner opening pull cable is often not properly assembled. For example, the inner opening pull cable may not be inserted downwards into place, meaning that the position where the inner opening pull cable is not properly assembled is higher than the position where it should be properly assembled. In this case, the inner opening pull cable may be in a tilted state.

[0004] However, operators cannot quickly determine whether the inner opening pull wire has been assembled in place during the actual assembly process, resulting in a low assembly yield. Utility Model Content

[0005] To address the aforementioned technical problems, this disclosure provides an inward-opening pull-wire structure, a car side door lock, a car door, and a vehicle.

[0006] In a first aspect, this disclosure provides an inwardly opening pull wire structure including an inwardly opening pull wire body and an extended mating part;

[0007] The inner opening pull cable body is used to connect with the inner opening linkage of the car side door lock, and the inner opening pull cable body is located on one side of the lock body linkage of the car side door lock.

[0008] The extended mating part is disposed on the side of the inner opening pull cable body near the lock body link, and at least a portion of the projection of the extended mating part on the lock body link is located within the contour area of ​​the lock body link.

[0009] The extended mating part can abut against the lock body link when the inner opening pull cable body and the inner opening link are connected in the first position, and can move to below the lock body link when the inner opening pull cable body and the inner opening link are connected in the second position, so as to release the abutment interference with the lock body link.

[0010] In some embodiments, when the extended mating part is located below the lock body link, the height gap between the extended mating part and the lock body link is no greater than 2 mm.

[0011] In some embodiments, the portion of the projection of the extended mating part on the lock body link that overlaps with the outline region of the lock body link has a dimension range of no more than 2 mm along the length direction of the inner opening pull cable body, and the direction from the inner opening pull cable body to the extended mating part is perpendicular to the length direction of the inner opening pull cable body.

[0012] In some embodiments, the extended mating portion is an extension block that protrudes toward the direction of the lock body link.

[0013] In some embodiments, the extension block is integrally formed with the inner opening pull wire body, and / or the top of the extension block is flush with the top of the inner opening pull wire body.

[0014] In some embodiments, the extension block has a dimension ranging from 3mm to 8mm along the length of the inner opening pull wire body;

[0015] And / or, the extension block has a dimension ranging from 1mm to 4mm in the height direction along the inner opening pull wire body;

[0016] And / or, the extension block has a dimension ranging from 2mm to 5mm in the width direction along the inner opening pull wire body.

[0017] In some embodiments, the inward-opening pull wire body includes a pull wire casting head and a pull wire connected to the pull wire casting head, wherein the pull wire casting head is used to cooperate with the inward-opening connecting rod.

[0018] The extended mating part is provided on the wire drawing head.

[0019] Secondly, this disclosure provides a car side door lock, including an inward opening linkage, a lock body linkage, and an inward opening cable structure as described above.

[0020] Thirdly, this disclosure provides a vehicle door, including the vehicle side door lock described above.

[0021] Fourthly, this disclosure provides a vehicle including the door as described above.

[0022] The technical solution provided in this disclosure has the following advantages compared with the prior art:

[0023] This disclosure provides an inward-opening pull-cord structure, an automotive side door lock, a vehicle door, and a vehicle. The inward-opening pull-cord structure includes an inward-opening pull-cord body and an extension mating portion. The inward-opening pull-cord body is used to connect with an inward-opening linkage of the automotive side door lock, and the inward-opening pull-cord body is located on one side of the lock body linkage of the automotive side door lock. The extension mating portion is disposed on the side of the inward-opening pull-cord body near the lock body linkage, and at least a portion of the projection of the extension mating portion onto the lock body linkage is located within the contour area of ​​the lock body linkage. The extension mating portion can abut against the lock body linkage when the inward-opening pull-cord body is connected to the inward-opening linkage in a first position, and can move to below the lock body linkage when the inward-opening pull-cord body is connected to the inward-opening linkage in a second position, so as to release the abutment interference with the lock body linkage. In other words, since at least part of the projection of the extended mating part onto the lock body link is located within the contour area of ​​the lock body link, meaning they are not completely offset, when the extended mating part and the lock body link make contact, it can be quickly determined that the inner opening pull cable body is not properly assembled. When the contact between the extended mating part and the lock body link is released, it indicates that the inner opening pull cable body is properly assembled. This allows for quick determination of whether the inner opening pull cable body is properly assembled, preventing incomplete assembly and thus improving the assembly yield.

[0032] To better understand the above-mentioned objectives, features, and advantages of this disclosure, the solutions disclosed herein will be further described below. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0033] Numerous specific details are set forth in the following description in order to provide a full understanding of this disclosure, but this disclosure may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some, and not all, of the embodiments of this disclosure.

[0034] Reference Figures 2 to 4 As shown, this embodiment provides an inwardly opening pull wire structure, including an inwardly opening pull wire body 1 and an extension mating part 2.

[0035] The inner opening pull cable body 1 is used to connect with the inner opening linkage 3 of the car side door lock, and the inner opening pull cable body 1 is located on one side of the lock body linkage 4 of the car side door lock.

[0036] The extension fitting part 2 is provided on the side of the inner opening pull cable body 1 near the lock body link 4, and at least part of the projection of the extension fitting part 2 on the lock body link 4 is located within the contour area of ​​the lock body link 4.

[0037] The extension fitting part 2 can abut against the lock body link 4 when the inner opening pull cable body 1 and the inner opening link 3 are connected in the first position, and can move to the bottom of the lock body link 4 when the inner opening pull cable body 1 and the inner opening link 3 are connected in the second position, so as to release the abutment interference with the lock body link 4.

[0038] In specific implementation, refer to Figure 2 As shown, the inward-opening cable structure may include an inward-opening cable body 1 and an extension mating portion 2 connected to the side of the inward-opening cable body 1 near the lock body link 4. For example, the inward-opening cable body 1 may be at least partially located on the outer side of the lock body link 4 along the width direction of the vehicle, and the extension mating portion 2 may have its projection on the lock body link 4 at least partially located within the contour area of ​​the lock body link 4, so that the extension mating portion 2 and the lock body link 4 may have an overlapping portion, that is, the two are not completely offset, so that the two can make contact to achieve abutment interference or can make contact abutment interference without contact.

[0039] Specifically, when the inner-opening pull cable body 1 and the inner-opening connecting rod 3 are connected in the first position, there will be abutment interference between the extension fitting part 2 and the lock body connecting rod 4. Therefore, it can be quickly determined that the inner-opening pull cable body 1 is not fully assembled at this time, that is, the first position is the position state where the inner-opening pull cable body 1 is not fully assembled. It should be noted that the abutment interference between the extension fitting part 2 and the lock body connecting rod 4 can be that the side of the extension fitting part 2 abuts against the side or top surface of the lock body connecting rod 4, or it can be that the top surface of the extension fitting part 2 abuts against the top surface or side of the lock body connecting rod 4. In short, there will be contact and abutment between the two.

[0040] When the inner opening pull cable body 1 and the inner opening connecting rod 3 are connected in the second position, the extension mating part 2 moves to the bottom of the lock body connecting rod 4. At this time, the extension mating part 2 and the lock body connecting rod 4 separate to release the obstruction. It can be determined that the inner opening pull cable body 1 has been assembled in place. That is, the second position is the position state in which the inner opening pull cable body 1 has been assembled in place.

[0041] It should be noted that the inward-opening pull cable body 1 is not fully assembled. Specifically, this can be understood as follows: the inward-opening connecting rod 3 is located below the lock body connecting rod 4, and the inward-opening connecting rod 3 has a insertion hole. The pre-set portion of the inward-opening pull cable body 1 needs to be fully inserted into the inward-opening connecting rod 3 through the insertion hole. When this pre-set portion is not fully inserted into the inward-opening connecting rod 3, the entire inward-opening pull cable body 1 is essentially not inserted downwards into place, resulting in the inward-opening pull cable body 1 being in a high installation position, and it may also be tilted upwards. For details, please refer to... Figure 1 The state shown. The assembly of the inner opening pull cable body 1 can be understood as follows: the preset part has been fully inserted into the inner opening connecting rod 3, and the entire inner opening pull cable body 1 will not have any problem of tilting up.

[0042] In other words, since at least a portion of the projection of the extension fitting 2 onto the lock body link 4 lies within the contour area of ​​the lock body link 4, meaning they are not completely offset, when the extension fitting 2 and the lock body link 4 come into contact, it can be quickly determined that the inner opening pull cable body 1 is not properly assembled. When the contact between the extension fitting 2 and the lock body link 4 is released, it indicates that the inner opening pull cable body 1 is properly assembled. This allows for quick determination of whether the inner opening pull cable body 1 is properly assembled, preventing the inner opening pull cable body 1 from being improperly assembled, thereby improving the assembly yield.

[0043] That is, in this embodiment, by setting the extension mating part 2 to cooperate with the lock body connecting rod 4, the structure ensures that the assembly worker cannot install it incorrectly. It can effectively help the assembly worker to assemble the inner opening pull cable body 1 in place, solve the problem of the inner opening pull cable 12 not being installed properly in some car side door locks, reduce factory rework time, reduce after-sales customer complaints, and enhance the product's market competitiveness.

[0044] Reference Figures 2 to 4 As shown, in some embodiments, when the inner-opening pull cable body 1 and the inner-opening connecting rod 3 are connected in the second position, the extended mating part 2 is located below the lock body connecting rod 4.

[0045] In other words, the inner opening link 3 is located at the bottom of the lock body link 4. When the inner opening pull cable body 1 and the inner opening link 3 are assembled in place, that is, after the inner opening pull cable body 1 is installed downward to the preset position, the extension mating part 2 is also located at the bottom of the lock body link 4. Therefore, there will be no mutual interference between the lock body link 4 and the extension mating part 2. Thus, it can be determined that the inner opening pull cable body 1 has been assembled in place, so as to prevent the phenomenon of the inner opening pull cable body 1 not being assembled in place, thereby improving the assembly yield.

[0046] It should be noted that after the inward-opening pull cable body 1 is assembled, the extended mating part 2 is at the bottom of the lock body connecting rod 4. However, the projections of the two still overlap, meaning that they only have a height gap in the height direction, but not in the length direction along the inward-opening pull cable 12 plate (refer to...). Figures 2 to 3 The two parts are completely offset in the x direction (as shown) to ensure that they have overlapping parts. This avoids the misalignment setting from causing the inability to make contact or disengagement between the extended mating part 2 and the lock body connecting rod 4 to determine whether the inward pull cable body 1 is installed in place.

[0047] Reference Figures 2 to 4 As shown, in some embodiments, when the extension mating part 2 is located at the bottom of the lock body connecting rod 4, the height gap between the extension mating part 2 and the lock body connecting rod 4 is no greater than 2mm. By reasonably setting the gap between the two, the mutual interference between them can be eliminated, thus determining that the inner opening pull wire 12 plate has been assembled in place, without causing the overall thickness of the entire inner opening pull wire structure to be too large.

[0048] For example, the height gap between the extension mating part 2 and the lock body connecting rod 4 can be referenced. Figure 4 As shown in H. The height gap H between the extension fitting part 2 and the lock body connecting rod 4 can be 2mm, or the height gap H between the extension fitting part 2 and the lock body connecting rod 4 can be 1.8mm, or the height gap H between the extension fitting part 2 and the lock body connecting rod 4 can be 1.6mm.

[0049] Reference Figures 2 to 4As shown, in some embodiments, the portion of the projection of the extension mating part 2 on the lock body link 4 that overlaps with the outline area of ​​the lock body link 4 has a size range of no more than 2 mm along the length direction of the inner opening pull cable body 1, and the direction from the inner opening pull cable body 1 to the extension mating part 2 is perpendicular to the length direction of the inner opening pull cable body 1.

[0050] Specifically, the direction from the inner pull cable body 1 to the extension mating part 2 is referenced. Figure 2 and Figure 4 The y-direction shown refers to the length direction of the inner drawstring body 1. Figure 2 and Figure 4 The x-direction shown indicates that these two directions are perpendicular. The dimension of the portion of the projection of the extension fitting part 2 onto the lock body link 4 that overlaps with the outline area of ​​the lock body link 4 along the length of the inner opening pull line body 1 can be referenced. Figure 4 As shown in L.

[0051] As described above, the extension mating part 2 is located at the bottom of the lock body connecting rod 4, but the projections between the two still overlap, meaning they only have a height gap in the height direction, but not in the length direction of the inner pull cable body 1 (refer to...). Figures 1 to 3 The extension fitting part 2 is completely offset in the x-direction shown. At this time, the overlapping part of the projection of the extension fitting part 2 on the lock body link 4 and the outline area of ​​the lock body link 4 has a size range of no more than 2mm along the length direction of the inner opening pull cable body 1, so as to ensure that the two are not offset but the overall size of the inner opening pull cable structure is not too large.

[0052] For example, the portion of the projection of the extension fitting part 2 on the lock body link 4 that overlaps with the outline area of ​​the lock body link 4 can have a dimension L of 2 mm, 1.8 mm, or 1.6 mm along the length direction of the inner opening pull line body 1.

[0053] Reference Figure 2 As shown, in some embodiments, the extension fitting part 2 is an extension block 21 protruding towards the direction of the lock body connecting rod 4. The extension block 21 changes its abutting relationship with the lock body connecting rod 4 when the inner opening pull cable body 1 is inserted and moved to determine whether the inner opening pull cable body 1 is assembled in place.

[0054] For example, the extension block 21 can be a rectangular block, or it can be any structure such as a spherical structure or a triangular structure.

[0055] For example, the extension block 21 is integrally formed with the inner opening pull wire body 1, thereby saving manufacturing steps and improving the overall structural strength of the inner opening pull wire structure.

[0056] In practice, the top of the extension block 21 can be set to be flush with the top of the inner opening pull cable body 1. This ensures both aesthetics and allows for better interference or de-interference with the lock body linkage 4 through the extension block 21.

[0057] In some embodiments, the extension block 21 extends along the length direction of the inner opening pull wire body 1 (refer to...). Figure 3 The dimension range in the x-direction shown is 3mm-8mm. By reasonably setting the dimension range of the extension block 21 along the length of the inner opening pull cable body 1, it is ensured that the extension block 21 has a suitable volume, so that it can abut against the lock body connecting rod 4 without causing the entire inner opening pull cable structure to be too large.

[0058] For example, the extension block 21 extends along the length of the inner pull wire body 1 (refer to...). Figure 3 The dimension in the x-direction shown can be 3mm, 5mm, or 8mm.

[0059] For example, the extension block 21 is in the height direction along the inner opening pull wire body 1 (refer to...) Figure 2 The dimension range in the z-direction (as shown) is 1mm-4mm. By reasonably setting the dimension range of the extension block 21 along the length of the inner opening pull cable body 1, it is ensured that the extension block 21 has a suitable volume, so that it can abut against the lock body connecting rod 4 without causing the entire inner opening pull cable structure to be too large.

[0060] For example, the extension block 21 is in the height direction along the inner opening pull wire body 1 (refer to...) Figure 2 The dimension in the z-direction shown can be 1mm, 2mm, or 4mm.

[0061] Extension block 21 is located along the width direction of the inner opening pull line body 1 (refer to...) Figure 2 The dimension range in the y-direction shown is 2mm-5mm. By reasonably setting the dimension range of the extension block 21 along the length of the inner opening pull cable body 1, it is ensured that the extension block 21 has a suitable volume, so that it can abut against the lock body connecting rod 4 without causing the entire inner opening pull cable structure to be too large.

[0062] For example, the extension block 21 is in the width direction along the inner opening pull line body 1 (refer to...) Figure 2 The dimension in the y-direction shown can be 2mm, 4mm, or 5mm.

[0063] Reference Figure 2As shown, in some embodiments, the inward-opening pull wire body 1 includes a pull wire casting head 11 and a pull wire 12 connected to the pull wire casting head 11. The pull wire casting head 11 is used to cooperate with the inward-opening connecting rod 3. An extension mating part 2 is provided on the pull wire casting head 11.

[0064] For example, the wire drawing head 11 can be as follows: Figure 2 The Z-shaped structure shown can also be other shapes. In addition, the wire drawing head 11 and the wire 12 can be integrally formed to save manufacturing steps and improve the structural strength of the entire inward-opening wire drawing body 1.
