Description

Technical Field

[0001] This utility model relates to the field of machinery, and in particular to a mechanically concealed flip-up door handle for vehicles. Background Technology

[0002] Existing new energy vehicles typically employ concealed door handle designs to reduce wind resistance and improve aesthetics. For example, utility model patent CN 222436135 U discloses a concealed car door handle and its assembly, including a base for connecting to the car door, a handle connected to the base, and a pivot penetrating both the base and the handle. The handle can rotate relative to the base around the axis of the pivot. It also includes a detachable limiting block connected to the base to prevent the pivot from disengaging from the base. However, the problem is that opening the door is achieved by pressing one end of the handle, which can easily lead to accidental opening of the door (e.g., on vibrating roads or due to accidental pressing), posing a risk. Therefore, improvements are needed. Furthermore, automatic return is usually achieved using a torsion spring, but this requires the torsion spring's return force to be precisely enough to cause the handle to return (i.e., the torsion spring's torque is 0 in the naturally closed state). The force cannot be too large or too small, making adjustment and installation difficult. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model proposes a mechanically concealed flip-up door handle for vehicles.

[0004] The objective of this utility model is achieved through the following technical solution:

[0005] A mechanically concealed flip-up door handle for a vehicle includes an upper handle and a lower handle; the top of the upper handle is hinged to the top of the outer end of the door handle groove by a first torsion spring, and the lower handle is hinged to the bottom of the outer end of the door handle groove by a second torsion spring; the free ends of the upper handle and the free ends of the lower handle are arranged opposite each other and close the door handle groove.

[0006] The upper ends of the arc-shaped guide plates are fixedly connected to both sides of the lower handle. Arc-shaped slides are formed on the arc-shaped guide plates, and spherical grooves are formed at the lower end of the arc-shaped slides.

[0007] A limiting groove is formed at the inner end of the handle groove; a limiting rod is connected to the bottom surface of the limiting groove through an elastic element, and the bottom of the limiting rod is spherical and fits into a spherical groove.

[0008] The upper handle is connected to an arc-shaped transmission arm that cooperates with the lower handle; in its natural state, the free end of the arc-shaped transmission arm contacts the inner wall of the handle groove; the bottom of the limiting rod is engaged in a spherical groove.

[0009] In a further improvement, both the first torsion spring and the second torsion spring are clip springs.

[0010] In a further improvement, the elastic element is a compression spring.

[0011] As a further improvement, both ends of the upper handle are connected to arc-shaped transmission arms that cooperate with the lower handle.

[0012] In a further improvement, the first torsion spring and the second torsion spring, in their natural state, respectively cause the free ends of the upper handle and the lower handle to maintain a torque that rotates inward toward the handle groove.

[0013] The beneficial effects of this utility model are as follows:

[0014] This invention uses a torsion spring, an arc-shaped transmission arm, a limiting rod, and an arc-shaped guide plate to limit the upper and lower handles respectively. In its natural state, the torsion spring maintains the torsion state, which also keeps the upper and lower handles in a naturally closed state. This reduces the installation requirements, improves the installation efficiency, and extends the service life of the handles. Attached Figure Description

[0015] The present invention will be further described with reference to the accompanying drawings, but the content of the drawings does not constitute any limitation on the present invention.

[0016] Figure 1 This is a schematic diagram of the upper and lower handle switches of this utility model.

[0017] Figure 2 This is a front structural diagram of the upper and lower handles;

[0018] Figure 3 This is a schematic diagram of the structure in which the limiting rod and the limiting groove cooperate. Detailed Implementation

[0019] To make the purpose, technical solution and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and examples. Example

[0020] like Figure 1 and Figure 2 The vehicle mechanical hidden flip door handle shown includes an upper handle 1, a first torsion spring 11, an arc-shaped transmission arm 12, a lower handle 2, a second torsion spring 21, a limiting groove 3, a limiting rod 4, an elastic element 5, an arc-shaped guide plate 6, an arc-shaped slide rail 61, and a spherical slot 611.

[0021] The upper handle 1 and the lower handle 2 are both hinged to the outer end of the handle groove and cooperate with each other to close the handle groove.

[0022] The upper handle 1 and the lower handle 2 are automatically rebounded by the first torsion spring 11 and the second torsion spring 21, respectively.

[0023] In its natural state, the first torsion spring (11) and the second torsion spring (21) respectively maintain a torque that rotates the free ends of the upper handle (1) and the lower handle (2) toward the inside of the handle groove. To counteract this torque and maintain the balance of the upper handle 1, the upper handle 1 is connected to an arc-shaped transmission arm 12 that cooperates with the lower handle 2; in its natural state, the free end of the arc-shaped transmission arm 12 contacts the inner wall of the handle groove. In this way, the arc-shaped transmission arm 12 will give the upper handle 1 an outward thrust opposite to that of the first torsion spring 11, thereby maintaining the balance of the upper handle 1. At the same time, the first torsion spring 11 does not need to maintain a torque of 0 in its natural state, but rather a torque > 0, thus making it easier to adjust and install.

[0024] Similarly, in order to maintain the balance of the lower handle 2, the upper ends of the arc-shaped guide plate (6) are fixedly connected to both sides of the lower handle (2). An arc-shaped slide (61) is formed on the arc-shaped guide plate (6), and a spherical groove (611) is formed at the lower end of the arc-shaped slide (61). A limiting groove (3) is formed at the inner end of the handle groove. A limiting rod (4) is connected to the bottom surface of the limiting groove (3) through an elastic element. The bottom of the limiting rod (4) is spherical and fits into the spherical groove (611). In this way, the limiting rod (4) inserted into the spherical groove (611) achieves the opposite and equal resistance to the second torsion spring (21), maintaining the balance of the lower handle 2. At the same time, the second torsion spring 21 does not need to maintain a torque of 0 in its natural state, but rather a torque > 0 state, thus making it easier to adjust and install.

[0025] like Figure 1 As shown, its specific usage process is as follows:

[0026] 1. Normal closed state: The upper and lower handles are aligned, and the entire structure is closed.

[0027] 2. When opening the door (apply slight pressure to spring back):

[0028] The user gently presses down on the handle to overcome the spring force, causing the handle to open and reveal hand space.

[0029] 3. Pull the top handle to open the door:

[0030] - The user pulls the upper handle (the upper handle is connected to the actuator that opens the car door (which is prior art and is not shown)) to open the car door. At the same time, the arc-shaped transmission arm 12 squeezes the already opened lower handle to reset it. Then, the user releases the handle, and the upper handle returns to its original position through the reset spring, restoring the entire door to a closed state.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the essence and scope of the technical solution of this utility model.
