Description

Technical Field

[0001] The invention relates to a vehicle door handle, and in particular to an automatic hiding and extending device for a vehicle door outer handle which has a more stable and simple structure, linear translation and precise positioning. Background Art

[0002] With the rapid development of the automobile industry, all kinds of automobile parts are pursuing high technology and high quality. The novelty of the vehicle's external handle is crucial to the overall aesthetics of the vehicle. The vehicle's door handles have evolved from the past exposed type to the more beautiful and convenient automatic extended hidden type. The spare parts industry has also put forward high requirements for the accuracy of hidden handles, that is, when the handle is retracted and hidden, the circumferential gap between the handle and the handle hole in the door is 2mm. Therefore: when the handle is hidden, if there is a small error, the circumferential gap of 2mm will be very obvious, which will seriously affect the overall appearance of the vehicle. In addition, because the handle is frequently used, high requirements are put forward for its technical structure and production quality.

[0003] There are also many technical solutions for hidden handles that are currently in use and disclosed. For example, the invention application with application number 2017109195634 discloses a hidden car exterior door handle. Although its structure is simple and reasonable, it can be fully implemented. Another example is the utility model with patent number 2019203504821, which also discloses a hidden car exterior door handle structure. Their technical structures are similar and basically represent the existing technical solutions.

[0004] The horizontal quadrilateral folding principle is adopted. Although its structure is reasonable and feasible, it is based on the principle of four-link axial connection, so its hiding and extension have an arc, and it cannot move linearly. Also, because there are many axial connection points, it will have problems such as low accuracy and complex structure. And because the connecting rod has a relative length, the connecting rod may be deformed during its production and use, resulting in low yield rate and other problems.

[0005] Currently, there is also a vertical quadrilateral folding and stretching principle, which is also being implemented, but it cannot avoid the various problems mentioned above.

[0006] In view of this, those skilled in the art have attempted to develop an automatic hiding and extending device for an outer door handle that is more stable, simple, linearly movable, and accurately positioned. Summary of the invention

[0016] A further preferred solution of the present invention is that a traction hanger is fixedly arranged on the inner side of the handle on the same side as the door opening linkage mechanism, a wire groove and a fixing hole are arranged on the handle traction wheel, a traction rope is arranged in the wire groove and the fixing hole between the handle traction wheel and the traction hanger, an inner reset spring is arranged on the linkage shaft between the handle traction wheel and the lower side of the inner sleeve frame, and the inner reset spring uses the handle traction wheel and the traction rope to always tighten the handle on the same side inward;

[0017] The torsion force of the inner return spring is relatively small.

[0018] A further preferred solution of the present invention is that: the linkage shaft and the door opening actuator are fixedly arranged, the upper side of the door opening actuator is movably sleeved with a door opening traction member, the door opening traction member is provided with a traction groove and a fixing hole, and the traction groove and the fixing hole are provided with a door opening cable;

[0025] The advantages of the present invention are:

[0026] 1. The handle extends and retracts in a straight line, and does not extend and hide in an arc like a four-bar linkage, so it has better accuracy.

[0027] Second, the use of extended straight slots and driving inclined slots to replace the existing quadrilateral connecting rod structure makes the slot holes less prone to deformation and has fewer shaft joints, so the stability will be better.

[0053] like Figures 1 to 5As shown: an automatic hidden extension device for an outer door handle, comprising a base frame 1, a hidden handle, a door opening linkage mechanism 4 and an electric retractor 29, the base frame 1 comprising an inner sleeve frame 11, an outer sleeve frame 13 and an outer mounting plate 14, the hidden handle comprising a translational connector 31 and a handle 37, an extension straight groove 21 is respectively arranged on the left and right sides of the upper and lower sides of the inner sleeve frame 11, a driving sleeve frame 12 is movably sleeved on the outer side of the inner sleeve frame 11, a driving inclined groove 22 is respectively arranged on the left and right sides of the upper and lower sides of the driving sleeve frame 12 corresponding to the extension straight groove 21, and the driving sleeve frame 12 can move left and right relative to the inner sleeve frame 11;

[0054] The left and right sides of the translation connecting member 31 are respectively provided with sliding shafts 32, and the upper and lower ends of the left and right sliding shafts 32 slide between the intersections of the left and right extending straight grooves 21 and the driving inclined grooves 22 on the upper and lower sides respectively;

[0055] The left and right movement of the driving sleeve 12 can utilize the interaction between the driving inclined groove 22 and the extended straight groove 21 on the sliding shaft 32 to drive the translational connecting member 31 to move inward and outward in the inner sleeve 11.

[0056] like Figure 2 , 4 8: A stretch spring 19 is provided between one end of the inner sleeve frame 11 and one end of the driving sleeve frame 12. The stretch spring 19 always moves the driving sleeve frame 12 to the right, and under the action of the driving inclined groove 22 on the sliding shaft 32, the translation connecting member 31 is always hidden inside the inner sleeve frame 11;

[0057] A buffer and silencer contact piece 28 is provided on the right side of the driving sleeve 12 , and an electric telescopic device 29 is provided on the right side of the base frame 1 . The electric telescopic device 29 includes a motor, a reducer and a telescopic rod, and the outer end of the telescopic rod abuts against the buffer and silencer contact piece 28 .

[0058] The sliding shafts 32 on the left and right of the translational connecting member 31 are restricted in the vertical and horizontal extension straight grooves 21 of the inner sleeve frame 11. By utilizing the left and right movement of the driving inclined grooves corresponding to the vertical and horizontal extension straight grooves 21 arranged on the driving sleeve frame 12, the sliding shafts 32, the translational connecting member 31 and the handle 37 are subjected to linear inward and outward movement (hiding and popping out). This technical solution is simple and practical, and has more accurate positioning and better stability than the existing technical solution.

[0059] The inner frame 11 and the outer frame 13 are designed as an integral whole, and the outer mounting plate 14 can be integral with them, or can be installed and fixed as an integral whole later.

[0060] like Figures 3 to 6 , 10: The left and right sides of the translational connecting member 31 are respectively fixedly provided with a shaft connecting member 33 and a stopper 35, and the right end of the handle 37 is axially connected to the shaft connecting member 33;

[0061] A handle spring 39 is provided on the axial connection between the handle 37 and the axial connection member 33 , and the handle spring 39 always presses the left end of the handle 37 inward.

[0062] like Figures 6 to 10 As shown: a door opening linkage mechanism 4 is movably arranged on the lower left side of the base frame 1, and the door opening linkage mechanism 4 includes a handle traction wheel 41 movably arranged in the inner sleeve frame 11 and a door opening actuator 47 movably arranged on the lower side of the outer sleeve frame 13, and a linkage shaft 42 is fixedly arranged on the lower side of the handle traction wheel 41, and the linkage shaft 42 passes through the lower side of the inner sleeve frame 11 and the lower side of the outer sleeve frame 13, and a door opening actuator 47 is arranged on the lower end of the linkage shaft 42.

[0063] like Figures 6 to 9 As shown: a traction hanger 38 is fixedly arranged on the inner side of the handle 37 on the same side of the door opening linkage mechanism 4, a wire groove and a fixing hole are arranged on the handle traction wheel 41, a traction rope 43 is arranged in the wire groove and the fixing hole between the handle traction wheel 41 and the traction hanger 38, and an inner return spring 45 is arranged on the linkage shaft 42 between the handle traction wheel 41 and the lower side of the inner sleeve frame 11. The inner return spring 45 uses the handle traction wheel 41 and the traction rope 43 to always tighten the handle 37 on the same side inward;

[0064] The torsion force of the inner return spring 45 is small, and only needs to be reset.

[0065] like Figure 6 , 9 As shown: the linkage shaft 42 and the door opening actuator 47 are fixedly arranged, and the upper side of the door opening actuator 47 is movably sleeved with a door opening traction member 46, and the door opening traction member 46 is provided with a traction groove and a fixing hole, and the traction groove and the fixing hole are provided with a door opening cable;

[0066] An external return spring 49 is provided between the door opening traction member 46 and the lower side of the coat rack 13, and the external return spring 49 always tightens the door opening cable by using the door opening traction member 46;

[0067] The torsion force of the external return spring 49 is small, and only needs to be reset.

[0068] like Fig. 9 As shown: a door opening top member 471 is provided on the door opening actuator 47, and the door opening traction member 46 includes a door opening force block 461 that can contact the door opening top member 471.

[0069] like Figure 2 , 4As shown in 10: damping racks 25 are fixedly arranged on the upper and lower sides of the driving sleeve frame 12, and dampers 26 are arranged on the upper and lower sides of the corresponding outer sleeve frame 13, and the damping racks 25 are meshed with the gears of the dampers 26. The arrangement of the damping racks 25 and the dampers 26 can make the handle 37 more cushioning and safer when it is retracted and hidden. The damping racks 25 and the dampers 26 can also be arranged as a set.

[0070] like Figure 2 , 5 As shown: the upper and lower sides of the inner sleeve frame 11 and the upper and lower sides of the driving sleeve frame 12 are respectively fixed with mutually matching translation grooves 23 and translation slide bars 24, and the upper and lower translation grooves 23 are each provided with an installation gap area A230, and the upper and lower translation slide bars 24 are each provided with an installation gap area B240.

[0071] like Fig.11 , 12 As shown, the upper and lower sides of the driving sleeve frame 12 and the upper and lower sides of the outer sleeve frame 13 are respectively fixed with mutually matching translation slide bars B241 and translation slots B231, and the upper and lower translation slide bars B241 and the upper and lower translation slots B231 are each provided with an installation gap area. The installation gap area is provided for installing the driving sleeve frame 12.

[0072] The driving sleeve frame 12 can utilize the translation slide bar 24 to cooperate with the translation slide groove 23 on the inner sleeve frame 11, such as Figure 2 , 5 As shown, this is a combined technical solution.

[0073] The driving sleeve frame 12 can also utilize the translation slide bar B241 to cooperate with the translation slide groove B231 on the outer sleeve frame 13, such as Fig.11 , 12 As shown, this is another combined technical solution.

[0074] When installing the drive sleeve 12, from the inside to the outside, align the installation gap area A230 and the installation gap area B240 and push them flat, and then move them to the left. Figure 4 , 11 shown.

[0075] Under the interaction between the translational slide groove 23 and the translational slide bar 24 , the driving sleeve 12 can only move left and right relative to the inner sleeve 11 , and the left and right movement of the driving sleeve 12 can drive the translational connector 31 and the handle 37 to perform inward and outward linear movement.

[0076] like Figure 6 As shown, the inner side of the outer frame 13 is provided with installation notches for the slide shaft 32, so that the inner end of the driving inclined groove 22 is completely exposed to facilitate the installation of the slide shaft 32.

[0077] When installing the translational connector 31, first move the drive sleeve 12 to the right until the inner end of the drive inclined groove 22 is aligned with the extended straight groove 21, and put the translational connector 31 into the inner sleeve 31, and then install the left and right sliding shafts 32 in the translational connector 31 from the upper and lower sides. Figure 4 The slide shaft 32 can be designed to be four pieces, left and right, up and down, or two pieces, left and right.

[0078] Under the action of the extension spring 19, the driving sleeve 12 always moves to the right, so that the translation connecting member 31 is located inside the inner sleeve 11 (hidden state), as shown in FIG. Figure 8 shown.

[0079] The installation of the handle 37 is relatively simple and will not be elaborated in detail in this application.

[0080] The door opening traction mechanism 4 is provided for mechanical door opening of the vehicle; however, it can also be designed as a touch-sensitive electric door opening, that is, a touch sensor is provided on the inner side of the handle 37, and an electromagnetic or electric door catch device is provided between the vehicle door and the vehicle door frame, and the two are electrically connected through the vehicle-mounted controller. When people's hands grasp the handle 37, the door can be automatically opened.

[0081] The handle traction wheel 41 and the linkage shaft 42 are integrally formed. The upper sides of the inner frame 11 and the outer frame 13 are each provided with a mounting hole 16 . The diameter of the mounting hole 16 is larger than the diameter of the handle traction wheel 41 , so that the handle traction wheel 41 can be easily installed into the mounting hole 16 .

[0082] The handle traction wheel 41 is arranged on the left side of the translation connecting member 31, and the two do not affect each other.

[0083] Installation instructions for door opening traction mechanism 4: Fig. 9 As shown: an inner return spring 45 (with a small torque and can be reset) is first put on the linkage shaft 42, passed through the mounting hole 16, and the lower end of the linkage shaft 42 is passed through the shaft holes on the lower sides of the inner sleeve frame 11 and the outer sleeve frame 13; the round block on the lower side of the handle traction wheel 41 is the force point of one end of the inner return spring 45, and the other end is subjected to force on the inner sleeve frame 11; the triangular block on the lower side of the outer sleeve frame 13 is the force point of one end of the outer return spring 49, and the other end is subjected to force on the upper side of the door opening traction member 46; the outer return spring 49 (with a small torque and can be reset) and the door opening traction member 46 are sleeved on the lower end of the linkage shaft 42, and then the door opening actuator 47 is fixed; the traction rope 43 is installed between the handle traction wheel 41 and the traction hanger 38 in the left end of the handle 37.

[0084] When the handle 37 is hidden, the door opening top member 471 fixed on the door opening actuator 47 is at a distance from the door opening force block 461 in the door opening traction member 46. Figure 2 , 9 shown.

[0085] When the handle 37 pops outward and stretches (i.e., the electric retractor 29 stretches after the vehicle's master lock is unlocked by the remote control), the door opening top member 471 fixed on the door opening actuator 47 just contacts the door opening force block 461 in the door opening traction member 46. Figure 3 , 9 shown.

[0086] When one end of the handle 37 is pulled outward, Figure 6 , 9 As shown: the door opening top member 471 drives the door opening force block 461, which drives the door opening traction member 46 to rotate, and the door opening cable installed on the door opening traction member 46 is used to open the door.

[0087] The electric telescopic device 29 on the right side of the base frame 1 is installed last; and the damper 26 is installed on the upper and lower sides or one side of the outer coat frame 13.

[0088] like Figure 8 As shown in the figure, the telescopic rod in the electric telescopic device 29 is arranged in a contacting manner (rather than connected) with the buffer and silencer contact member 28 fixed on the right side of the driving sleeve 12, so that the door can be opened manually in case the electric telescopic device 29 is out of power or fails. Fig.13 As shown: when the right end of the axial connection point between the handle 37 and the axial connection member 33 is pressed inward, the left end will pop outward. At this time, the handle 37 can be pulled out by hand to open the door.

[0089] like Figure 8 As shown: when the vehicle is started or the main lock is locked, the translational connector 31 and the handle 37 are automatically hidden.

[0090] like Figure 1 , 3 As shown: when the master lock is opened, the translation connecting member 31 and the handle 37 automatically extend and pop out.

[0091] The above is a detailed introduction to the present invention. Specific examples are used in this article to illustrate the principles and implementation methods of the present invention. The description of the above embodiments is only used to help understand the core idea of ​​the present invention and is not intended to limit the present invention.
