[0022] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.

[0023] In this disclosure, unless otherwise stated, directional terms such as "upper" and "lower" generally refer to the upper and lower positions of a door handle in use; "inner" and "outer" refer to the inner and outer contours of the corresponding components; and "far" and "near" refer to the distance of a corresponding structure or component from or near another structure or component. Furthermore, the terms "first," "second," etc., used in this disclosure are for distinguishing one element from another and do not imply sequentiality or importance. In addition, in the following description, when referring to the accompanying drawings, unless otherwise explained, the same reference numerals in different drawings denote the same or similar elements. The above definitions are for explanation and illustration only and should not be construed as limiting this disclosure.

[0024] The purpose of this disclosure is to provide a door handle 100, a vehicle door, and a vehicle, wherein the door handle can be applied to a vehicle door, and the vehicle door can be applied to a vehicle. The door handle 100 can improve the overall aesthetics, and at the same time, it can open the cover 120 by inserting the opening member 200 into the opening slot 101 to satisfy the mechanical unlocking function.

[0025] To achieve the above objectives, according to the first aspect of this disclosure, such as Figures 1 to 8As shown, a door handle 100 is provided, which includes a door handle body 110 and a cover plate 120. The door handle body 110 includes a mechanical unlocking component; the cover plate 120 is detachably snapped onto the front end of the door handle body 110 and covers the mechanical unlocking component. An opening slot 101 is formed at the junction of the cover plate 120 and the door handle body 110. The opening slot 101 is used for inserting an opening component 200 and for opening the cover plate 120 by rotating the opening component 200.

[0026] The door handle 100 disclosed herein, based on the above technical solution, includes a door handle body 110 and a cover plate 120. The door handle body 110 includes a mechanical unlocking component (e.g., a mechanical lock cylinder). The cover plate 120 is snapped onto the front end of the door handle body 110 and can conceal the mechanical unlocking component (not shown in the figure). An opening slot 101 is formed at the junction of the cover plate 120 and the door handle body 110. By inserting an opening component 200 (e.g., a car key) into the opening slot 101 and rotating the opening component 200, the cover plate 120 is opened, thereby enabling the door to be unlocked using the mechanical unlocking component. The door handle 100 improves the overall aesthetics by concealing the mechanical unlocking component of the door handle body 110 with the cover plate 120. Simultaneously, by inserting the opening component 200 into the opening slot 101 to open the cover plate 120, the door can be unlocked using the mechanical unlocking component, thus fulfilling the mechanical unlocking function.

[0027] It should be noted that the opening slot 101 is located at the junction of the cover plate 120 and the door handle body 110, that is, between the two. This limitation allows the opening member 200 to be inserted into the opening slot 101 and then rotated to lift the cover plate 120, thereby achieving the purpose of removing the cover plate 120.

[0028] The number of opening slots 101 can be multiple. By inserting the opening member 200 into different opening slots 101, the cover plate 120 and the door handle body 110 in different positions can be opened, thereby making it easier to remove the cover plate 120 from the door handle body 110.

[0029] The opening slot 101 can be located at any suitable position where the cover plate 120 and the door handle body 110 meet. To further improve the aesthetics of the cover plate 120, such as... Figure 1 and Figure 4As shown, in some embodiments of this disclosure, the opening slot 101 is located on the lower inner side of the cover plate 120. Specifically, the opening slot 101 is located on the lower front inner side of the cover plate 120. When a person observes from outside the vehicle towards the door, they see a single, continuous cover plate 120, and the opening slot 101 is not visible, thus ensuring the aesthetics of the door handle 100 and the door. It is understood that the description of the opening slot 101 being located on the lower inner side of the cover plate 120 is merely to describe its position. Structurally, the opening slot 101 can be a recess in the cover plate 120 alone, which, together with the door handle body 110, forms the opening slot 101; or it can be a recess in the door handle body 110 alone, which, together with the cover plate 120, forms the opening slot 101; or it can be a recess in both the cover plate 120 and the door handle body 110, with both recesses forming the opening slot 101.

[0030] In some embodiments, there may be two opening slots 101. Both opening slots 101 are located on the inner side of the lower end of the cover plate 120 and are spaced apart in the front-rear direction of the vehicle. The opening member 200 can open the cover plate 120 by inserting it into one of the opening slots 101 and rotating it upward.

[0031] The access slot 101 can be constructed in any suitable manner, such as Figure 2 and Figure 3 As shown, in some embodiments of this disclosure, the door handle body 110 has a first groove 111, and the cover plate 120 has a second groove 121. The first groove 111, the cover plate 120, and the second groove 121 form an opening slot 101. The door handle body 110 may have a first groove 111, the opening of which may face the cover plate 120. Correspondingly, the cover plate 120 has a second groove 121, which may correspond to the opening of the first groove 111. The first groove 111, the second groove 121, and the back of the cover plate 120 together form the aforementioned opening slot 101. When the opening element 200, such as a car key or other lever-like element (including but not limited to a screwdriver), can be inserted to a certain depth through the opening of the opening slot 101, and the cover plate 120 can be lifted upward by rotating the opening element 200 upward, so as to remove the cover plate 120, and then the mechanical unlocking element on the door handle body 110 located below the cover plate 120 can be unlocked by using the car key, so as to realize the mechanical unlocking of the car door in an emergency.

[0032] To avoid scratching or damaging the paint surface of cover 120 during the opening process, such as Figure 3 and Figure 4As shown, in some embodiments of this disclosure, the bottom of the second groove 121 has a protrusion 123 protruding towards the door handle body 110. The protrusion 123 abuts against the opening member 200, so that when the opening member 200 rotates, the protrusion 123 is subjected to force, thereby opening the cover plate 120 and preventing scratches on the surface of the cover plate 120 due to contact between other parts of the cover plate 120 and the opening member 200. It should be noted that the protrusion 123 can be any suitable shape. For example, it can be an arc-shaped protrusion, and the surface of the arc-shaped protrusion makes point contact, line contact, or surface contact with the opening member 200 inserted into the opening slot 101. Of course, the protrusion 123 can also be cylindrical or other polygonal shapes.

[0033] To ensure better contact between the protrusion 123 and the opening member 200, and to improve its strength under stress, such as Figure 4 and Figure 5 As shown, in some embodiments, the protrusion 123 includes an abutment platform 1231 for abutting against the opening member 200. When the opening member 200 is inserted into the opening slot 101, the gap between the abutment platform 1231 and the opening member 200 is greater than or equal to 0.2 mm. The protrusion 123 has abutment platform 1231 specifically designed for abutting against the opening member 200. This abutment platform 1231 plays a crucial role in the process of the opening member 200 being inserted into the opening slot 101 and the cover 120 being opened, and its design purpose is to achieve precise mutual cooperation with the opening member 200. When the opening member 200 is inserted into the opening slot 101 according to the above-described operation procedure, the gap between the abutment platform 1231 and the opening member 200 needs to be limited in order to facilitate smooth insertion of the opening member 200 into the opening slot 101. Typically, the gap size must be greater than or equal to 0.2mm. This value is determined through rigorous design calculations and extensive experimental verification. It ensures that the opening component 200 maintains a suitable distance from the contact platform 1231 during insertion into the opening slot 101. This prevents excessive friction and collision during insertion due to an insufficient gap, which could affect the normal insertion of the opening component 200 and potentially damage the contact platform 1231 and the opening component 200. Conversely, an excessive gap would prevent inaccurate positioning of the opening component 200 within the opening slot 101, which could affect subsequent collaborative work with other components of the device. Ultimately, this ensures the stable, reliable, and efficient operation of the entire device.

[0034] In some embodiments, in order to enable the opening member 200 to enter the interior of the opening slot 101 more quickly after being inserted through the opening of the opening slot 101, such as... Figure 8As shown, in some embodiments, the width H2 of the first groove 111 is greater than the width H1 of the second groove 121. Specifically, the width H2 of the first groove 111 is greater than the width H1 of the second groove 121, and the width H1 of the second groove 121 is greater than the width H of the opening member 200.

[0035] The relatively wide design of the first slot 111 is primarily to facilitate the easier inward movement of the opening element 200 during insertion. This provides ample space for the opening element 200 to move within the opening slot 101, ensuring smooth sliding and preventing jamming or obstruction due to limited space, thus guaranteeing the overall operating efficiency of the device. The relatively narrow width of the second slot 121 is designed to accommodate the dimensional accuracy requirements of the opening element 200, allowing for better positioning and constraint, improving its stability and accuracy. For example, when the opening element 200 is a car key, the width of the first slot 111 needs to be slightly larger than the width of the car key. For instance, a car key is typically about 6.4mm wide, while the width of the first slot 111 can be 7.2mm. This larger width provides sufficient clearance for easy key insertion. The width of the second slot 121, approximately 7.4mm, is also larger than the car key width, and slightly larger than the width of the first slot 111, facilitating better insertion of the car key into the opening slot 101.

[0036] For the design where the opening slot 101 is located at the lower end of the cover plate 120, to avoid interference between the door handle 100 and the insertion of the opening member 200, such as Figure 4 and Figure 7 As shown, in some embodiments of this disclosure, the door handle 100 has an opening slot 101 extending obliquely upward from the lower end of the cover plate 120 in the direction from the outside to the inside. The opening of the opening slot 101 is arranged obliquely outward relative to the recess 102 of the door handle 100 (used for electronic unlocking or pulling the door). This design facilitates the insertion of the opening member 200 into the opening slot 101 and provides operating space for easy upward rotation to open the cover plate 120.

[0037] like Figure 7As shown, in some embodiments, the angle α between the extending direction of the opening slot 101 and the vertical direction is 30-50°. To facilitate the insertion of the opening member 200 (e.g., a car key) into the opening slot 101, the opening of the opening slot 101 is inclined outward and downward. The specific inclination angle can be designed according to actual conditions. For example, the angle α between the extending direction of the opening slot 101 and the vertical direction is 30°, 35°, 40°, 45°, or 50°. For example, in one possible embodiment, the angle α between the extending direction of the opening slot 101 and the vertical direction is 30°. When the car key is inserted into the opening slot 101, the distance L between the tail of the car key and the door handle is 15mm. When the car key is rotated upward by 15°, the cover plate 120 disengages from the door handle body 110.

[0038] To ensure that the opening element 200 has sufficient lever arm when opening, such as Figure 5 As shown, in some embodiments, the depth D of the opening slot 101 is greater than or equal to 8 mm. According to actual operation or theoretical calculation, when the opening member 200 is inserted into the opening slot 101 to a depth greater than or equal to 8 mm, the cover plate 120 can be opened easily.

[0039] The opening element 200 can be any suitable structural component. For example, when the opening element 200 is a car key, the dimensions of the opening slot 101 need to meet the key insertion requirements. Therefore, in some embodiments, the opening slot 101 is configured to accommodate car key insertion. The depth and opening size of the opening slot 101 need to correspond to the dimensions of the corresponding position on the car key. For example, the width of the opening slot 101 needs to be greater than the width of the car key, and the thickness of the opening slot 101 needs to be greater than the thickness of the car key. It is understood that the approximate dimensions of the car key are 6.4mm (width) × 3mm (thickness), the opening width of the opening slot 101 (the width of the first slot 111) can be 7.2mm, and the opening thickness of the opening slot 101 (the thickness of the first slot 111) can be 3.2-3.5mm.

[0040] To achieve the snap-fit ​​connection between the cover plate 120 and the door handle body 110, such as Figure 2 , Figure 3 and Figure 4 As shown, in some possible embodiments, the cover plate 120 is provided with one of a buckle 122 and a slot 112, and the door handle body 110 is provided with the other of a buckle 122 and a slot 112. The buckle 122 and the slot 112 cooperate to connect the cover plate 120 to the door handle body 110.

[0041] To achieve a reliable connection between the cover plate 120 and the door handle body 110, a flexible and practical snap-fit ​​connection method is adopted. The cover plate 120 may have either a snap-fit ​​122 or a slot 112, while the door handle body 110 may have either a snap-fit ​​122 or a slot 112. This design provides two optional assembly combinations to meet different production process requirements and product designs. One option is that the cover plate 120 has a snap-fit ​​122, and the door handle body 110 has a slot 112. Another option is that the cover plate 120 has a slot 112, and the door handle body 110 has a snap-fit ​​122. It should be noted that both the cover plate 120 and the door handle body 110 can have multiple snap-fit ​​122s and slots 112, and they can correspond one-to-one.

[0042] During assembly, the snap fastener 122 and the slot 112 cooperate to establish the connection between the cover plate 120 and the door handle body 110. The snap fastener 122 typically possesses a certain degree of elastic deformation capability. Its structural design allows it to smoothly embed into the slot 112 through moderate elastic compression when mating with it. After embedding, it relies on its own elastic recovery force to tightly engage within the slot 112, thus achieving a stable connection. This connection method offers several advantages. Firstly, from an operational convenience perspective, the cooperation between the snap fastener 122 and the slot 112 is simple and intuitive, effectively improving assembly efficiency and reducing assembly time and labor costs during production and assembly. On the other hand, from the perspective of structural stability, once the buckle 122 and the slot 112 are engaged, they can provide reliable connection strength between the cover plate 120 and the door handle body 110, ensuring that even if the cover plate 120 is subjected to a certain degree of external force pulling, vibration or collision during the daily use of the product, it will not easily fall off the door handle body 110, thereby ensuring the integrity and stability of the overall structure of the product, and improving the durability of the product and the user experience.

[0043] The door handle 100 of this embodiment can be a semi-concealed door handle 100 based on the requirement to reduce wind resistance of the vehicle. This type of door handle 100 does not protrude from the outer surface of the door. To improve the tensile strength, a fixed semi-concealed door handle 100 is used. To improve the operation feel to match the electric door lock, the door handle 100 needs to have electronic operation buttons. At the same time, to ensure security, a mechanical unlocking channel (e.g., mechanical lock cylinder, outward opening cable) needs to be reserved. For aesthetic performance, the mechanical lock cylinder is not exposed. The cover plate 120 is detachably connected to the door handle body 110. An opening slot 101 is formed at the junction of the cover plate 120 and the door handle body 110. By inserting the opening member 200 (e.g., car key) into the opening slot 101 and turning the car key upward to open the cover plate 120, the car door can be unlocked by inserting the car key into the mechanical unlocking member (mechanical lock cylinder).

[0044] According to a second aspect of this disclosure, a vehicle door is provided, which includes a door body and the aforementioned door handle 100 disposed on the door body, and thus the vehicle door also has all the advantages of the door handle 100.

[0045] According to a third aspect of this disclosure, a vehicle is also provided that includes the aforementioned door, and thus the vehicle also possesses all the advantages of a door, which will not be elaborated upon here.

[0046] The present disclosure includes a door handle 100, a car door, and a vehicle. The door handle 100 includes a door handle body 110 and a cover plate 120. The door handle body 110 includes a mechanical unlocking component (e.g., a mechanical lock cylinder). The cover plate 120 is snapped onto the front end of the door handle body 110 and can cover the mechanical unlocking component. An opening slot 101 is formed at the junction of the cover plate 120 and the door handle body 110. By inserting an opening component 200 (e.g., a car key) into the opening slot 101 and rotating the opening component 200, the cover plate 120 is opened, thereby enabling the car door to be unlocked using the mechanical unlocking component. The door handle 100 improves the overall aesthetics of the door handle 100 by covering the mechanical unlocking component of the door handle body 110 with the cover plate 120. At the same time, after inserting the opening component 200 into the opening slot 101 to open the cover plate 120, the car door can be unlocked using the mechanical unlocking component, thus fulfilling the mechanical unlocking function.

[0047] The preferred embodiments of this disclosure have been described in detail above with reference to the accompanying drawings. However, this disclosure is not limited to the specific details of the above embodiments. Within the scope of the technical concept of this disclosure, various simple modifications can be made to the technical solutions of this disclosure, and these simple modifications all fall within the protection scope of this disclosure.

[0048] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction.
