Description

Technical Field

[0001] This utility model relates to the field of vehicle door handle technology, and in particular to a welded cover plate assembly and a vehicle upward-opening semi-concealed door handle containing the assembly. Background Technology

[0002] The descriptions in this section are provided only as background information relating to this disclosure and do not constitute prior art.

[0003] A flip-up semi-concealed door handle is a door opening solution that typically flips up after being pressed or touched, and the user then pulls the handle to open the door. It strikes a balance between optimized aerodynamics, aesthetics, and ease of operation, and is widely used in new energy and high-end gasoline vehicles. Traditional flip-up semi-concealed door handles generally employ both electric and mechanical backup mechanisms. Electric opening is used for normal opening, while the mechanical backup mechanism is typically used for manual opening in emergency situations such as electronic system malfunctions or collisions.

[0004] A semi-concealed handle connection mechanism is disclosed in the prior art, as described in utility model patent CN222949640U. This patent discloses a mechanism including a car door sheet metal, a handle base, a handle body, a switch cover, a fixing connector, and a limiting structure. The car door sheet metal has a handle hole with an inwardly extending mounting portion from the edge of the handle hole. The handle base has a cavity, and the handle body is installed in the cavity. The switch cover is fixed to the outside of the handle body. The fixing connector passes sequentially through the handle base, handle body, and mounting portion and is fixedly connected to the switch cover. The fixing connector is fastened to the switch cover and clamps the handle base, handle body, and mounting portion. The mechanism also includes a limiting mechanism disposed on the handle base for limiting the fixing connector. The limiting mechanism includes components disposed on the handle... The hook on the base is screwed in, causing the hook to deform elastically. When the screw is screwed in to the set position, the hook deforms and locks the screw. However, the related technologies, including the above-mentioned technical solutions, still have many problems. For example, in the handle reset mechanism, the hook is prone to elastic loss due to long-term repeated use and high temperature use, which restricts the service life of the handle. In addition, in order to improve the safety of vehicle use, some designs rely on the automatic switching to mechanical mode after the failure of the electronic system, such as the disengagement of the electromagnetic clutch. However, the switching mechanism itself may not be able to respond due to failure. While the independent pure mechanical mode is more reliable, it also has the problem of occupying a lot of space. Therefore, the handles in the existing technology generally have the problem of poor reliability of the electric and mechanical switching mechanism, which is not conducive to opening the door in emergency situations. Utility Model Content

[0005] The purpose of this utility model is to provide a welded cover plate assembly and a vehicle flip-up semi-concealed door handle containing the assembly, in order to solve the technical problems of the handle reset mechanism being prone to failure and having a short lifespan, the mechanical mode opening in emergency situations being structurally redundant and occupying a large space, and the poor reliability of the existing semi-concealed door handles.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A welded cover plate assembly, comprising:

[0008] The lower cover plate is rotatably mounted on the handle body, and it contacts the tactile switch when rotated.

[0009] An elastomer is slidably mounted on the lower cover plate and deforms under force when the lower cover plate rotates, thus contacting the handle body.

[0010] The top cover is mounted on the handle body and is used to securely mount the tactile switch.

[0011] A tactile switch, which is electrically connected to a handle drive mechanism, is used to open the door.

[0012] After the elastomer recovers its shape, the lower cover plate is rotated and reset by contacting the handle body at one end.

[0013] Furthermore, the elastomer is configured as a sheet structure, and has guide holes on it that slide in conjunction with the guide posts of the lower cover plate.

[0014] Furthermore, the elastic body is provided with a through hole for the contact to pass through. When the lower cover plate rotates, the contact comes into contact with the tactile switch on the upper cover plate to trigger the tactile switch.

[0015] Furthermore, the elastomer includes a middle portion, transition portions at both ends of the middle portion, and side portions on both sides of the transition portions along its length, wherein the width of the middle portion is greater than the width of the transition portions and the side portions.

[0016] Furthermore, the angle between the middle part and the transition part is α, the side part is parallel to the middle part, the length of the middle part is H1, the projection of the length of the transition part along the direction parallel to the middle part is H2, the length of the side part is H3, and the thickness of the elastic body is m, wherein 5° < α < 15°, 2H2 < H1 < 4H2, 3H3 < H2 < 5H3, and 3m < H3 < 5m.

[0017] Furthermore, the guide hole is shaped like a pentagram, with the diameter of the inscribed circle inside the pentagram being d and the diameter of the guide post being D, where 0 < Dd < 2mm.

[0018] Furthermore, the lower cover plate is also provided with a positioning boss, which is inserted into and cooperates with the positioning slot provided on the elastic body.

[0019] A semi-concealed door handle for vehicles with an upward flip-up design includes the aforementioned welded cover plate assembly, a bracket, a handle recess fixedly mounted on the bracket, and a handle body rotatably mounted on the bracket. A blocking portion is provided between the support arm of the handle body and the side arm of the bracket, which is used to increase the resistance when the handle body rotates relative to the bracket.

[0020] Furthermore, the blocking part is configured as L-shaped, and there is an included angle β between the free end of the blocking part and the connection between the free end and the side arm of the support, wherein 30° < β < 60°.

[0021] Furthermore, the free end of the blocking part is interference-fitted with the handle body support arm, and the interference between the outer surface of the free end and the handle body support arm is e, where 0.2mm < e < 3mm.

[0022] Compared with the prior art, the technical solution of this utility model has the following beneficial effects:

[0023] (1). By setting the specific structure of the welded cover plate assembly, the present invention uses an elastic body to compress the elastic body and rotate it towards the tactile switch when the lower cover plate is subjected to force, thereby triggering the tactile switch and driving the handle body to rotate around the bracket to realize the electric opening operation of the car door; at the same time, the lower cover plate is reset under the action of the elastic body. The simple structure realizes complex operation, with low failure rate, reducing the frequency of maintenance and replacement of parts, and extending service life.

[0024] (2). By setting a blocking part between the handle body and the bracket, this utility model realizes that in case of abnormal opening in an emergency, the external force must overcome the resistance of the blocking part and the return spring between the handle body and the bracket in order to open the door in an emergency, which greatly improves the safety of the door.

The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0043] To address the limitations of existing technologies, this embodiment provides a technical solution. The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0044] This utility model is mainly aimed at optimizing and improving the existing vehicle flip-up semi-concealed door handle, which has common problems such as high failure rate, short service life, and complex structure, large space occupation, and poor reliability in emergency opening. The specific improved structure is as follows.

[0045] See appendix Figure 1-5A welded cover plate assembly 100 includes: a lower cover plate 101, rotatably mounted on a handle body 400, which contacts a tactile switch 103 when rotated; the lower cover plate 101 is also provided with a positioning boss 1013, which is inserted into a positioning groove 1026 provided on an elastic body 102. It can be understood that the lower cover plate 101 is rotatably mounted to the handle body 400 via a rotating shaft 402 and a rotating sleeve. The insertion and engagement of the positioning boss 1013 and the positioning groove 1026 is to better achieve the positional positioning of the elastic body 102 after reset. The shape of the positioning boss 1013 can be rectangular, circular, or other shapes; the elastic body 102 is slidably mounted on the lower cover plate 101 and deforms under force when the lower cover plate 101 rotates, thus contacting the handle body 400.After the elastic body 102 returns to its original shape, it abuts against the handle body 400 at one end to achieve the rotational reset of the lower cover plate 101. Specifically, the elastic body 102 is configured as a sheet structure, and a guide hole 1024 is provided on it to slide and cooperate with the guide post 1011 of the lower cover plate 101. The guide hole 1024 can be circular or other shapes, and the number of guide holes 1024 is set to two. The elastic body 102 is provided with a through hole 1025 for the contact point 1012 to pass through. When the lower cover plate 101 rotates, the contact point 1012 contacts the tactile switch 103 on the upper cover plate 104 to trigger the tactile switch 103. It can be understood that the contact point 1012 is located on the lower cover plate 101. The columnar structure on the upper part can have a cross-shaped, circular, or other cross-shaped cross-section. The contact point 1012 is located in the middle between the two guide holes 1024. The elastic body 102 includes a middle part 1021, transition parts 1022 at both ends of the middle part 1021, and side parts 1023 on both sides of the transition parts 1022 along its length. It can be understood that the two ends of the middle part 1021 are the transition parts 1022, and the two sides of the transition parts 1022 are the side parts 1023. The side parts 1023 and the transition parts 1022 are symmetrically arranged with respect to the middle part 1021. The width of the middle part 1021 is greater than the width of the transition parts 1022 and the side parts 1023. The purpose of this arrangement is to increase the elastic body's elasticity. The overall strength of the elastic body 102 is such that the angle between the middle part 1021 and the transition part 1022 is α, and the side part 1023 is parallel to the middle part 1021. This means that the planes containing the middle part 1021 and the side part 1023 are perpendicular to the deformation direction of the elastic body 102. The length of the middle part 1021 is H1, the projection of the length of the transition part 1022 along the direction parallel to the middle part 1021 is H2, the length of the side part 1023 is H3, and the thickness of the elastic body 102 is m, where 5° < α < 15°, 2H2 < H1 < 4H2, 3H3 < H2 < 5H3, 3m < H3 < 5m. Preferably, α < 10°, H1 = 3H2, H2 = 4H3, H... 3 = 4m. This can be understood as setting the size relationship between the middle part 1021, the transition part 1022, and the edge part 1023, as well as their relationship with the thickness, to optimize the elasticity and strength of the elastic body 102. This ensures that the force required for the operator to rotate the lower cover of the handle socket 300 is moderate, greatly improving user comfort. The guide hole 1024 is shaped like a pentagon, with the diameter of the inscribed circle inside the pentagon being d, and the diameter of the guide post 1011 being D, where 0 < Dd < 2mm, preferably Dd = 1mm. This design facilitates smoother sliding of the elastic body 102 along the guide post 1011 while also providing guidance. The upper cover plate 104 is installed on the handle body 400 and used to fix the tactile switch 103.The tactile switch 103 is electrically connected to the handle drive mechanism to achieve the door opening action. It can be understood that the handle drive mechanism is a relatively conventional drive structure for door handles in the prior art, so it will not be described in detail here.

[0046] See appendix Figure 6-11 A semi-concealed, flip-up door handle for vehicles includes the aforementioned welded cover assembly 100. As described above, the lower cover 101 of the welded cover assembly 100 is rotatably mounted on the handle body 400, and the upper cover 104 of the welded cover assembly 100 is mounted on the handle body 400. It also includes a bracket 200, a handle recess 300 fixedly mounted on the bracket 200, and a handle body 400 rotatably mounted on the bracket 200. The handle body 400 rotates with the bracket 200 via a pivot 402 and a return spring 401 mounted on the pivot 402. The bracket 200 is installed with the vehicle body via a tolerance adjuster for the installation and reset action after rotation. The reset spring 401 is generally a torsion spring. Compared with conventional technology, the main improvement here is the blocking part 201. A blocking part 201 is provided between the arm of the handle body 400 and the side arm of the bracket 200. The blocking part 201 is used to increase the resistance when the handle body 400 rotates relative to the bracket 200. The purpose of increasing the resistance here is to prevent the door from being opened accidentally in the event of a collision or other abnormal external force due to insufficient resistance, thereby reducing the risk of vehicle use. The blocking part 201 is L-shaped, comprising a connecting part 2011 and a free end 2012. The free end 2012 is integrally formed with the bracket 200 through the connecting part 2011. An included angle β exists between the free end 2012 of the blocking part 201 and the side arm of the bracket 200, wherein 30° < β < 60°, preferably β < 45°. The free end 2012 of the blocking part 201 is interference-fitted with the arm of the handle body 400. The interference between the outer side of 2012 and the arm of the handle body 400 is e, where 0.2mm < e < 3mm. It can be understood that the setting of the β angle helps to reduce the impact force between the handle body 400 and the bracket 200 when the handle body 400 rotates, and avoids the impact force of the initial contact between the two being too large, which would reduce the service life of the blocking part 201. By setting the interference amount, the purpose of increasing the resistance between the handle body 400 and the bracket 200 is achieved. At the same time, the interference force of this interference fit is less than the torque of the return spring 401.

[0047] When using the vehicle flip-up semi-concealed door handle disclosed in this utility model, the operator's hand enters the handle recess 300 and acts on the lower cover plate 101, causing it to rotate around the handle body 400. At the same time, it compresses the elastic body 102, causing it to deform. The elastic body 102 abuts against the inner side of the handle body 400. At this time, the contact point 1012 on the lower cover plate 101 contacts the tactile switch 103, triggering the electric unlocking mechanism of the door to achieve normal opening. When the vehicle encounters an emergency and cannot be opened normally, the operator applies force to the lower cover plate 101, and the lower cover plate 101 transmits the force to the handle body 400. After overcoming the resistance of the return spring 401 and the blocking part 201, the handle body 400 can also achieve mechanical opening.

[0048] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.

[0049] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
