Description

Technical Field

[0001] This utility model belongs to the field of automotive interior and exterior technology, specifically a transmission structure for a concealed handle. Background Technology

[0002] Rotary concealed handles pop out by rotating around an axis. When in standby mode, they are flush with the door panel. When the door needs to be opened, they automatically or manually rotate to a certain angle to reveal the handle area, and then the user holds the handle and pulls it to unlock and open the door.

[0003] The transmission structure of a common rotary concealed door handle mainly consists of the handle body, handle shaft, rocker arm, and handle bracket.

[0004] When in use, the handle is popped out by the motor. The operator pulls the handle body, which rotates around the pivot. The ball head on the handle body presses the slide on the rocker arm, causing the rocker arm to rotate around the pivot. The other end of the rocker arm drives the pull cord to rotate, thus achieving the purpose of opening the door.

[0005] However, this structure also has some drawbacks. The rocker arm requires a very sturdy material, and since the slide rail on the rocker arm is integrated with the rocker arm, the slide rail material is also very hard. During operation, when the ball head presses against the rocker arm, there is a hard contact, which generates friction noise. Usually, a thin POM sleeve is put on the ball head to prevent noise through contact between the POM sleeve and the rocker arm slide rail. Although this can avoid noise, the ball head sleeve is very thin and is prone to breakage during use and installation, leading to functional failure. Therefore, we have developed a new structure to avoid these problems. Summary of the Invention

[0006] The technical solution of this utility model is as follows: a transmission structure for a concealed handle includes a handle body, a rocker arm, a drive block, and a bracket. The handle body is hinged to the bracket via a handle pivot. The end of the handle body is provided with a handle body ball joint, which is slidably connected to the drive block slide. A spring is indirectly connected to the handle body. When the handle body is pulled, the handle body ball joint can be driven to move within the drive block slide. The handle body is reset by the spring. A rocker arm is provided on the bracket, and a drive block slide is also provided on the bracket. The drive block is engaged with the rocker arm. When the handle body ball joint reciprocates within the drive block slide, it drives the rocker arm and the drive block to rotate around the rocker arm pivot. One end of the rocker arm pivot passes through the rocker arm and the drive block in sequence and is engaged with the rocker arm and the drive block. After the handle body rotates, the handle body ball joint can connect with the drive block on the rocker arm pivot. The handle body ball joint reciprocates within the rocker arm slide.

[0007] Furthermore, the drive block is provided with a protruding structure, and the rocker arm is provided with a grooved structure, with the protruding structure and the grooved structure engaging.

[0008] The beneficial effects of this utility model are as follows: It reduces the noise generated when the handle ball head and the slide rail rub against each other, and avoids the possibility of the handle ball head sleeve breaking during installation and use. Attached Figure Description

[0019] It should be noted that in the description of this utility model, the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", "clockwise", "counterclockwise", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation.

[0020] In this utility model, unless otherwise explicitly specified and limited, the terms "setting," "installing," "connecting," and "joining" should be interpreted broadly. For example, "fixing" can mean a fixed connection, a detachable connection, or an integral part; a connection can be a mechanical connection or an electrical connection; a joint can be a direct connection or an indirect connection through an intermediate medium, and can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0021] A transmission structure for a concealed handle includes a handle body 1, a rocker arm 2, a drive block 4, and a bracket 5. The handle body 1 is hinged to the bracket 5 via the handle pivot 6. The handle body 1 has a handle body ball head 101 at its end. The handle body ball head 101 is slidably connected to the drive block slide 402. When the handle body 1 is pulled, the handle body ball head 101 can move within the drive block slide 402. The handle body 1 is reset by a spring.

[0022] The bracket 5 is equipped with a drive block slide 402.

[0023] Drive block 4 is engaged with rocker arm 2. The drive block 4 is provided with a protrusion structure 401, and the rocker arm 2 is provided with a groove structure 201. The protrusion structure 401 and the groove structure 201 can be engaged and matched.

[0024] After the drive block 4 and the rocker arm 2 are matched, they can be regarded as a whole. When the ball head 101 of the handle body reciprocates in the drive block slide 402, it drives the rocker arm 2 and the drive block 4 to rotate about the rocker arm pivot 3.

[0025] One end of the rocker arm shaft 3 passes through the rocker arm 2 and the drive block 4 in sequence, and is engaged with the rocker arm 2 and the drive block 4. After the handle body 1 is rotated, the ball head 101 of the handle body can be connected to the drive block 4 on the rocker arm shaft 3.

[0026] The rocker arm 2 reciprocates within the rocker arm slide 3.

[0027] This invention removes the ball head sleeve from the handle body and the slide rail from the rocker arm. A new part called a drive block is added on this basis. The drive block is made of POM structure and has a slide rail. The drive block and the rocker arm are coaxial and connected together by some structure. When the ball head of the handle presses the ball head of the drive block, the drive block drives the rocker arm to rotate together. The other end of the rocker arm pulls the pull line to open the door.

[0028] The structure includes the drive block, rocker arm, and bracket mounting structure; the structure where the handle ball head presses the drive block when the handle is rotated, causing the drive block to rotate the rocker arm; the structure where the drive block has a slide rail; the structure where the protrusion on the drive block interlocks with the rocker arm; the structure where the groove on the rocker arm interlocks with the drive block; and the selection of POM material for the drive block.

[0029] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any modifications, equivalent substitutions, and improvements made by those skilled in the art within the scope of the technology disclosed in this utility model, and within the spirit and principles of this utility model, should be included within the protection scope of this utility model. Furthermore, all content not described in detail in this specification belongs to the prior art known to those skilled in the art.

[0030] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.
