Description

TECHNICAL FIELD

[0001] The utility model relates to door handle technical field, in particular to a kind of installation structure of hidden outer handle. BACKGROUND

[0002] The installation point of the hidden outer handle cannot be directly set on the outer panel of the door due to its aesthetic design, but is arranged on the reinforcing plate inside the outer panel of the door. The reinforcing plate and the outer panel of the door are connected by welding, and there is a certain non-eliminable error. Therefore, the installation and positioning method needs to have a certain adjustable range to ensure the accuracy and stability of the handle installation position. Currently, the handle base can move axially relative to the adjusting ring to accommodate the manufacturing error between the reinforcing plate and the positioning point of the outer panel of the door, control the gap difference of the hidden outer handle, and ensure the aesthetic purpose by fixing the adjusting ring (with threads on the outer periphery) on the reinforcing plate and assembling the handle base and the adjusting ring by threads.

[0003] The current adjusting ring is of an integral structure. In order to reduce the difficulty of demolding of the adjusting ring, only a small number of thread turns are usually provided on the outer periphery of the adjusting ring. The small number of thread turns limits the adjusting range of the adjusting ring to the handle base. When the manufacturing error between the reinforcing plate and the positioning point of the outer panel of the door is large, the handle cannot be installed. SUMMARY

[0004] The purpose of the utility model is to provide an installation structure of a hidden outer handle to solve the problem that the adjusting ring cannot realize a large adjusting range due to the restriction of demolding difficulty in the prior art.

[0016] In some embodiments of the present application, the locking member further comprises a first abutting platform and a second abutting platform.

[0017] The lower end of the side of the second plate towards the clamping plate has a first inclined surface, which extends from top to bottom away from the clamping plate, so as to form an inclined groove on the side of the second plate towards the clamping plate, and the bottom wall of the inclined groove constitutes the first abutting platform.

[0018] The lower end of the side of the clamping plate towards the second plate has a second inclined surface, which extends from top to bottom towards the second plate, so as to form a protruding part on the side of the clamping plate towards the second plate, and the bottom wall of the protruding part constitutes the second abutting platform.

[0019] The protruding part is accommodated in the inclined groove, so that the first abutting platform and the second abutting platform are clamped.

[0020] In some embodiments of the present application, the upper end of the side of the clamping plate towards the second plate has a third inclined surface, which extends from top to bottom towards the second plate.

[0021] In some embodiments of the present application, the mounting structure of the hidden outward-opening handle further comprises a pressing ring and a bolt; the pressing ring comprises a first semicircular ring and a second semicircular ring; the first semicircular ring is coaxially connected to the inner wall of the first half-cylindrical portion, and the second semicircular ring is coaxially connected to the inner wall of the second half-cylindrical portion; the first semicircular ring and the second semicircular ring are flush on the side away from the vehicle door panel; the first half-cylindrical portion and the second half-cylindrical portion are combined into the cylindrical external threaded member, and the first semicircular ring and the second semicircular ring are combined to form the pressing ring, and the space surrounded by the first semicircular ring and the second semicircular ring forms a through hole.

[0022] The bolt comprises a head end and a screw rod; along the first direction, the projection of the through hole is located within the projection range of the head end, the screw rod passes through the through hole, and the head end is pressed against the side of the pressing ring away from the vehicle door panel.

[0023] In some embodiments of the present application, the first semicircular ring is coaxially connected to a third semicircular ring on the side facing the second semicircular ring.

[0024] Along the first direction, the second semicircular ring and the cylindrical external threaded member are arranged at intervals on one end of the vehicle door panel, so that the space on the side of the second semicircular ring facing the vehicle door panel forms a matching accommodation cavity for the third semicircular ring, and the third semicircular ring is accommodated in the accommodation cavity.

[0025] In some embodiments of the present application, the first half-cylindrical portion and / or the second half-cylindrical portion is provided with a semicircular protruding edge on the outer peripheral wall near one end of the vehicle door panel, and the semicircular protruding edge extends towards the axial center line direction away from the cylindrical external threaded member.

[0026] In some embodiments of the present application, the first half-cylindrical portion and / or the second half-cylindrical portion has a stop portion away from one end of the vehicle door panel, and the stop portion has a stop position and a retracted position.

[0029] The stop portion protrudes outward from the mounting groove at least partially in a direction away from the axial centerline of the cylindrical external threaded part. The stop portion has a connecting end connected to the mounting groove and a free end away from the connecting end. Pressing the free end toward the inner cavity of the first half-cylinder and / or the second half-cylinder causes the stop portion to move from the stop position to the retracted position. Releasing the pressing of the free end causes the stop portion to move from the retracted position to the stop position.

[0030] Compared with the prior art, the installation structure of the concealed outward-opening handle of this utility model has the following advantages: This solution sets a first half-cylinder with a first thread and a second half-cylinder with a second thread, and assembles the two to form a cylindrical external threaded part. Since the threads are all set on the first and second half-cylinders, demolding can be completed simply by pushing the first and second half-cylinders. Compared with the traditional integrated adjustment ring, there is no need to set an additional rotating mechanism for demolding, reducing the cost of mold investment and having higher economic benefits. The split setting method in this solution makes the number of thread turns on the outer circumference of the assembled cylindrical external threaded part no longer limited by the demolding difficulty, thereby greatly improving the adjustment range of the cylindrical external threaded part and meeting the requirements of handle installation even when there is a large manufacturing error between the positioning points of the reinforcing plate and the outer door panel.

[0051] As Figure 12 Shown, for the handle base 9 is installed in the vehicle door plate 10 structure schematic diagram of cylindrical outer threaded part 1;Handle base 9 is internally threaded cylinder with thread in the inside, handle is installed on handle base 9;Vehicle door plate 10 includes the outer plate 101 of door and the reinforcing plate 102 of welding connection with outer plate 101 of door, hidden outer opening handle is fixedly installed on the reinforcing plate 102 located in the inside of outer plate 101 of door through handle base 9 connected therewith;As Figures 1-11 Shown, the application embodiment proposes a kind of installation structure of hidden outer opening handle, for handle base 9 is installed in the reinforcing plate 102 located in the inside of outer plate 101 of door, including first half cylinder part 11 and second half cylinder part 12;The outer periphery of first half cylinder part 11 has first threaded portion 111, and the outer periphery of second half cylinder part 12 has second threaded portion 121, and the thread rotation direction of first threaded portion 111 and second threaded portion 121 is matched;When first half cylinder part 11 and second half cylinder part 12 are spliced to form cylindrical outer threaded part 1, so that the outer periphery of cylindrical outer threaded part 1 has intermittent thread (as Figure 1 、 Figure 11The handle base 9 can be screwed on the outer periphery of the cylindrical outer threaded member 1, and the cylindrical outer threaded member 1 has a first direction X extending along its axial direction, and a locking member is arranged at the joint of the first half-cylinder part 11 and the second half-cylinder part 12, so as to lock and position the first half-cylinder part 11 and the second half-cylinder part 12 when the first half-cylinder part 11 and the second half-cylinder part 12 are combined into the cylindrical outer threaded member 1. The combination of the first half-cylinder part 11 and the second half-cylinder part 12 is as follows: adjust the positions of the first half-cylinder part 11 and the second half-cylinder part 12 in the first direction X, so that the first half-cylinder part 11 and the second half-cylinder part 12 are arranged at intervals in the first direction X, and then move the first half-cylinder part 11 in the first direction X (the second half-cylinder part 12 remains stationary), or move the second half-cylinder part 12 in the first direction X (the first half-cylinder part 11 remains stationary), or move the first half-cylinder part 11 and the second half-cylinder part 12 in the first direction X (the moving directions of the first half-cylinder part 11 and the second half-cylinder part 12 are opposite). During the above movement, it is necessary to ensure that the first half-cylinder part 11 and the second half-cylinder part 12 are kept in contact on one side. When the first half-cylinder part 11 and / or the second half-cylinder part 12 are moved to a predetermined position (i.e., when the two ends of the first half-cylinder part 11 and the second half-cylinder part 12 in the first direction X are flush), the locking member locks and positions the first half-cylinder part 11 and the second half-cylinder part 12. When the cylindrical outer threaded member 1 is installed on the reinforcing plate 102 (the handle base 9 is screwed on the outer periphery of the cylindrical outer threaded member 1), the first half-cylinder part 11 and the second half-cylinder part 12 will not move relative to each other, ensuring the stability of the overall structure of the cylindrical outer threaded member 1.

[0052] During installation, the cylindrical outer threaded member 1 is screwed into the handle base 9 from one end, achieving threaded connection between the cylindrical outer threaded member 1 and the handle base 9, and then the cylindrical outer threaded member 1 is fixedly installed on the reinforcing plate 102, thereby achieving installation of the handle. Since the handle base 9 and the cylindrical outer threaded member 1 can move axially, the support error between the installation point of the reinforcing plate 102 and the positioning point of the door outer panel 101 is eliminated, and the handle is installed on the reinforcing plate 102, thereby controlling the gap difference of the hidden outward-opening handle and ensuring the aesthetic appearance.

[0053] The cylindrical outer threaded part 1 in the scheme is provided in a split type, and is spliced by the first half cylinder part 11 and the second half cylinder part 12. When the first half cylinder part 11 and the second half cylinder part 12 are processed, only simple flat pushing is needed to complete the demolding of the first half cylinder part 11 and the second half cylinder part 12 from the mold (that is, the first half cylinder part 11 and the second half cylinder part 12 are withdrawn from the mold along the direction perpendicular to the length direction of the mold), avoiding the problem that the traditional integral adjusting ring is difficult to demold and only a small number of threads are arranged on the outer periphery of the adjusting ring (if a large number of threads are arranged on the outer periphery of the integral adjusting ring, the demolding needs to be performed in a rotating manner, and the demolding process is similar to the cutting process of a screw and a thread. The rotation out of the mold needs to increase rotating mechanisms such as rotating shafts, bearings, and transmission devices, which increases the complexity of demolding), and the adjusting range of the handle base 9 is limited. The first half cylinder part 11 and the second half cylinder part 12 designed in the scheme are no longer restricted by the demolding difficulty, and a large number of threads can be arranged on the outer periphery of the first half cylinder part 11 and the second half cylinder part 12, so that the cylindrical outer threaded part 1 spliced and the handle base 9 have a large adjusting range between them, and the manufacturing error between the reinforcing plate 102 and the positioning point of the outer plate 101 of the vehicle door can be large, and the handle can also be installed.

[0054] As shown in some embodiments of the present application, Figure 1 , Figure 2 , Figure 3 The locking part includes a clamping plate 21 and a clamping groove 22 (the clamping plate 21 and the clamping groove 22 form a radial locking part 2). The clamping plate 21 is arranged on the side of the first half cylinder part 11 facing the second half cylinder part 12 (the splicing position of the first half cylinder part 11), and extends towards the inner side of the cylindrical outer threaded part 1. Preferably, the clamping plate 21 extends along the radial direction of the first half cylinder part 11 and towards the axial center line of the first half cylinder part 11. The clamping plate 21 has two clamping plates 21, and the two clamping plates 21 are symmetrically arranged at the two splicing positions on the side of the first half cylinder part 11 facing the second half cylinder part 12. The clamping groove 22 is arranged on the side of the second half cylinder part 12 facing the first half cylinder part 11, and extends along the first direction X. The clamping groove 22 has two clamping grooves 22, and the two clamping grooves 22 are symmetrically arranged at the two splicing positions on the side of the second half cylinder part 12 facing the first half cylinder part 11. That is, each clamping plate 21 corresponds to a clamping groove 22. The first half cylinder part 11 and the second half cylinder part 12 are arranged at intervals along the first direction X, and the splicing positions on the opposite sides of the first half cylinder part 11 and the second half cylinder part 12 are attached,

[0055] Then, the first half cylinder part 11 and / or the second half cylinder part 12 are moved along the first direction X, so that the clamping plate 21 is clamped into the corresponding clamping groove 22 (as shown in Figure 4As shown), this restricts the radial movement between the first half-cylinder 11 and the second half-cylinder 12.

[0056] In some embodiments of this application, such as Figure 3 , Figure 4 As shown, the snap-fit ​​groove 22 includes a first plate 221, a second plate 222, and a third plate 223; the first plate 221 is connected to the joint of the second semi-cylindrical portion 12 facing the first semi-cylindrical portion 11, and the first plate 221 extends toward the inner side of the cylindrical external threaded part 1; preferably, the first plate 221 extends radially along the second semi-cylindrical portion 12 and toward the direction close to the axial center line of the second semi-cylindrical portion 12; the second plate 222 is perpendicularly connected to the end of the first plate 221 near the axial center line of the second semi-cylindrical portion 12, and the second plate 222 extends into the inner cavity of the first semi-cylindrical portion 11; the third plate 223 is perpendicularly connected to the end of the second plate 222 away from the first plate 221, and the third plate 223 extends toward the direction away from the axial center line of the second semi-cylindrical portion 12; so that the space enclosed between the first plate 221, the second plate 222, and the third plate 223 forms the snap-fit ​​groove 22; as Figure 4 As shown, the outer peripheral wall of the snap-fit ​​plate 21 is fitted with the inner wall of the snap-fit ​​groove 22, thereby enabling the restriction of radial movement between the first half-cylinder portion 11 and the second half-cylinder portion 12 when the snap-fit ​​plate 21 enters into the snap-fit ​​groove 22 along the first direction X and snaps into the snap-fit ​​groove 22.

[0057] In some embodiments of this application, such as Figure 7 As shown, the locking member also includes a first abutment platform 312 and a second abutment platform 322; the lower end of the second plate 222 facing the latching plate 21 has a first inclined surface 311, which extends from top to bottom away from the latching plate 21 to form a groove 31 on the side of the second plate 222 facing the latching plate 21, and the bottom wall of the groove 31 forms the first abutment platform 312; the lower end of the latching plate 21 facing the second plate 222 has a second inclined surface 321, which extends from top to bottom towards the second plate 222 to form a protrusion 32 on the side of the latching plate 21 facing the second plate 222, and the bottom wall of the protrusion 32 forms The second abutment platform 322; the protrusion 32 and the inclined groove 31 form an axial locking part 3; in this embodiment, after adjusting the relative position between the first half-cylinder 11 and the second half-cylinder 12, the first half-cylinder 11 is kept stationary, and the second half-cylinder 12 moves from top to bottom along the first direction X, causing the locking plate 21 to gradually enter into the corresponding locking groove 22, so that when both ends of the first half-cylinder 11 and the second half-cylinder 12 along the first direction X are kept flush, the protrusion 32 on the locking plate 21 just enters into the inclined groove 31, and the first abutment platform 312 and the second abutment platform 322 abut against each other (e.g. Figure 7As shown), at this time, the first half-cylinder 11 and the second half-cylinder 12 abut against the reinforcing plate 102 on the side facing the reinforcing plate 102. Under the abutting cooperation between the first abutting platform 312 and the second abutting platform 322, the movement of the first half-cylinder 11 and the second half-cylinder 12 along the first direction X is restricted. The first half-cylinder 11 and the second half-cylinder 12 are locked in the first direction X, so that the cylindrical external threaded part 1 as a whole has strong structural stability (making the splicing between the first half-cylinder 11 and the second half-cylinder 12 more firm, stable and not easy to loosen), ensuring the stability and accuracy of the installation and adjustment process between the cylindrical external threaded part 1 and the handle base 9, and avoiding the failure rate caused by the loosening between the first half-cylinder 11 and the second half-cylinder 12.

[0058] In this embodiment, along the first direction X, as the second semi-cylindrical portion 12 moves downward, the snap-fit ​​groove 22 is engaged with the snap-fit ​​plate 21 on the first semi-cylindrical portion 11. During this process, when the bottom of the second plate 222 moves close to the protrusion 32, the bottom of the second plate 222 is compressed by the second inclined surface 321. As the second semi-cylindrical portion 12 continues to move downward, the lower end of the second plate 222 deforms to a certain extent towards the axial centerline of the second semi-cylindrical portion 12 (in this embodiment, the first semi-cylindrical portion 11, the second semi-cylindrical portion 12, the snap-fit ​​plate 21, the first plate 221, the second plate 222, and the third plate 223 are all plastic structural parts with a certain degree of deformation elasticity). When both ends of the first semi-cylindrical portion 11 and the second semi-cylindrical portion 12 are flush along the first direction X, the protrusion 32 on the snap-fit ​​plate 21 is just accommodated in the inclined groove 31 on the second plate 222 (e.g., ...). Figure 7 As shown), and the first abutting platform 312 and the second abutting platform 322 abut against each other, thereby achieving axial locking and positioning between the first half-cylinder 11 and the second half-cylinder 12.

[0059] In some embodiments of this application, such as Figure 7 As shown, the upper end of the snap-fit ​​plate 21 facing the second plate 222 has a third inclined surface 211. The third inclined surface 211 extends from top to bottom toward the second plate 222. The setting of the third inclined surface 211 allows the snap-fit ​​plate 21 to smoothly and easily enter the snap-fit ​​groove 22 when the second plate 222 moves from top to bottom with the second half-cylinder 12. The setting of the third inclined surface 211 has a guiding effect.

[0060] In some embodiments of this application, such as Figure 4As shown, the hidden outward-opening handle adjustable mounting structure further comprises a pressing ring 4 and a bolt 6; the pressing ring comprises a first semicircular ring 41 and a second semicircular ring 42; the first semicircular ring 41 is coaxially connected to the inner wall of the first half-cylindrical portion 11, and the second semicircular ring 42 is coaxially connected to the inner wall of the second half-cylindrical portion 12; the first semicircular ring 41 and the second semicircular ring 42 are flush with the side away from the reinforcing plate 102; when the first half-cylindrical portion 11 and the second half-cylindrical portion 12 are combined into the cylindrical external threaded part 1, the space between the first semicircular ring 41 and the second semicircular ring 42 forms the through hole 5 (at this time, the first semicircular ring 41 and the second semicircular ring 42 are combined to form the pressing ring 4); as shown Figure 5 As shown, the bolt 6 comprises a head end 61 and a screw rod 62; along the first direction X, the projection of the through hole 5 is located in the projection range of the head end, and the size of the head end 61 is larger than the size of the through hole 5, so that the screw rod 62 can pass through the through hole 5 and be screwed into the nut 63 arranged on the reinforcing plate 102, and the head end 61 cannot pass through the through hole 5 due to the size being larger than the through hole 5, and the head end 61 is pressed against the side of the pressing ring 4 away from the reinforcing plate 102, thereby achieving the fixed mounting of the cylindrical external threaded part 1 on the reinforcing plate 102.

[0061] As shown in some embodiments of the present application, Figure 2 , Figure 5 As shown, the first semicircular ring 41 is coaxially connected with a third semicircular ring 43 on the side facing the second semicircular ring 42 (the third semicircular ring 43, the first semicircular ring 41, and the first half-cylindrical portion 11 are integrally arranged); as shown Figure 3 , Figure 8As shown, along the first direction X, the second half ring 42 is arranged at an interval between the cylindrical outer thread 1 and one end of the reinforcing plate 102, so that the space on the side of the second half ring 42 facing the reinforcing plate 102 forms a receiving cavity 122 matched with the third half ring 43, and the third half ring 43 is received in the receiving cavity 122; when the two parts are spliced, the second half cylinder 12 is moved from top to bottom along the first direction X, so that the two clamping plates 21 arranged on the side of the first half cylinder 11 facing the second half cylinder 12 enter the corresponding clamping grooves 22, until the protrusions 32 on the clamping plates 21 just enter the inclined grooves 31 on the second plate 222 (at this time, the splicing of the cylindrical outer thread 1 is completed), and at the same time, the third half ring 43 is just completely received in the receiving cavity 122, and the upper surface of the third half ring 43 abuts against the lower surface of the second half ring 42; at this time, the first half ring 41 and the second half ring 42 are spliced to form the pressing ring 4, and at the same time, the abutting of the third half ring 43 and the second half ring 42 also achieves the locking positioning of the first half cylinder 11 and the second half cylinder 12 in the first direction X; in cooperation with the first abutting table 312 and the second abutting table 322, reliable positioning of the first half cylinder 11 and the second half cylinder 12 in the first direction X is achieved (under the cooperation of the above two structures, the first half cylinder 11 and the second half cylinder 12 cannot move in the first direction X), which further improves the stability of the structure of the spliced cylindrical outer thread 1 and helps to improve the accuracy of the adjustment and installation between the cylindrical outer thread 1 and the handle base 9.

[0062] As shown in some embodiments of the present application, Figure 2 , Figure 3 As shown, a half-ring protrusion 13 is arranged on the outer peripheral wall of the first half cylinder 11 and / or the second half cylinder 12 close to one end of the vehicle door plate 10, and the half-ring protrusion 13 extends away from the axial center line of the cylindrical outer thread 1; when the spliced cylindrical outer thread 1 is screwed into the handle base 9, the end of the cylindrical outer thread 1 away from the half-ring protrusion 13 is screwed into the handle base 9 first, and then the threaded assembly between the cylindrical outer thread 1 and the handle base 9 is achieved; when the handle base 9 is threadedly connected to the outer periphery of the cylindrical outer thread 1, the arrangement of the half-ring protrusion 13 (so that the handle base 9 cannot be pulled out of the cylindrical outer thread 1 from the end where the half-ring protrusion 13 is arranged) can reduce the probability of the handle base 9 being pulled out of the cylindrical outer thread 1, and avoid the cylindrical outer thread 1 from being lost due to misoperation.

[0063] In some embodiments of the present application, in order to further reduce the probability of the cylindrical outer thread 1 being pulled out of the handle base 9 due to misoperation, as shown in Figure 2 , Figure 3As shown, a stop portion 7 is provided at the end of the first semi-cylindrical portion 11 and / or the second semi-cylindrical portion 12 away from the reinforcing plate 102. The stop portion 7 has a stop position and a retracted position. In the natural state, the stop portion 7 is in the stop position (the stop portion 7 protrudes outward from the first semi-cylindrical portion 11 and / or the second semi-cylindrical portion 12), which is used to stop the handle base 9 threaded to the cylindrical external threaded component 1. It cooperates with the semi-annular protrusion 13 provided at the other end of the first semi-cylindrical portion 11 and / or the second semi-cylindrical portion 12 to jointly restrict the cylindrical external threaded component 1 within the handle base 9, so that the cylindrical external threaded component 1 will not easily come out of the handle base 9 under a certain external force. Figure 12 As shown, after the handle is installed, the handle base 9 must pass through the stop 7 to be removed from the cylindrical external threaded part 1. Therefore, the stop 7 also prevents the handle base 9 from coming off the cylindrical external threaded part 1 later (ensuring a reliable connection between the handle and the vehicle door panel 10). When the stop 7 is in the retracted position (the stop 7 no longer protrudes outward from the first half-cylinder 11 and / or the second half-cylinder 12), the stop 7 will not hinder the axial movement between the cylindrical external threaded part 1 and the handle base 9, and the cylindrical external threaded part 1 can be removed from the handle base 9.

[0064] In some embodiments of this application, such as Figure 9 , Figure 11 As shown, the first semi-cylindrical portion 11 and / or the second semi-cylindrical portion 12 have a mounting groove 8 for accommodating the stop portion 7 at the end away from the vehicle door panel 10. The mounting groove 8 is provided radially through the first semi-cylindrical portion 11 and / or the second semi-cylindrical portion 12. The stop portion 7 protrudes outward from the mounting groove 8 at least partially in a direction away from the axial centerline of the cylindrical external thread member 1 to achieve a stopping effect. The stop portion 7 has a connecting end 71 connected to the mounting groove 8 and a free end 72 away from the connecting end 71. (The free end 72 does not contact the inner wall of the mounting groove 8). Press the free end 72 towards the inner cavity of the first half-cylinder 11 and / or the second half-cylinder 12, so that the stop part 7 moves from the stop position to the retracted position (the stop part 7 no longer protrudes outward from the mounting groove 8), so that the stop part 7 no longer obstructs the axial movement between the cylindrical external threaded part 1 and the handle base 9, so that the cylindrical external threaded part 1 can be screwed out from the handle base 9 (after releasing the pressure on the free end 72 of the stop part 7, the stop part 7 moves from the retracted position to the stop position). The stop part 7 in this solution is a plastic structural part with certain elastic deformation characteristics. When the free end 72 of the stop part 7 is pressed, the connecting end 71 of the stop part 7 can produce a certain degree of elastic bending deformation.

[0065] The working process of the utility model is: firstly, the first half cylinder part 11 and the second half cylinder part 12 are spliced, the first half cylinder part 11 and the second half cylinder part 12 are stably kept in respective states under the action of the locking part, and the stability of the cylindrical external screw part 1 structure is ensured; then the cylindrical external screw part 1 is screwed into the handle base 9 (the installation between the handle base 9 and the cylindrical external screw part 1 is completed), subsequently the cylindrical external screw part 1 is fixedly installed on the reinforcing plate 102 through the bolt 6, and the installation process of the handle is realized.

[0066] In conclusion, the utility model embodiment provides a kind of installation structure of hidden external handle, and the first half cylinder part 11 with first threaded portion 111 and the second half cylinder part 12 with second threaded portion 121 are set, and the two are spliced to form cylindrical external screw part 1, since thread is all set on the first half cylinder part 11 and the second half cylinder part 12 in half cylinder, so that it is only necessary to simply push when demoulding first half cylinder part 11, second half cylinder part 12, and demoulding can be completed, compared with traditional integrated adjusting ring, without setting additional mechanism for demoulding rotation, reduce the cost investment of mould, with higher economic benefit;In the scheme, the way of split setting is adopted, so that the number of thread turns of the cylindrical external screw part 1 spliced is no longer limited, and then the adjustment range of the cylindrical external screw part 1 can be greatly improved, to meet the case that there is larger manufacturing error between reinforcing plate 102 and vehicle door outer plate 101 positioning point, realize the installation of handle.

[0067] The above is only preferred embodiment of the utility model, and it should be pointed out that, for ordinary skilled person in the art, without departing from the technical principle of the utility model, a number of improvements and substitutions can be made, and these improvements and substitutions should be regarded as the protection range of the utility model.
