Description

Technical Field

[0001] The utility model relates to the technical field of vehicle door handles, and more specifically, to a hidden vehicle door handle and a door handle assembly thereof. Background Art

[0002] Hidden car door handles are a frequently used element in modern car design. Similar to traditional car door handles, hidden car door handles can be completely integrated into the car body when not in use, thereby improving the overall appearance and aerodynamic performance of the car. Currently, most forms of hidden door handles are fixed at one end through a handle shaft. When one end is pressed externally or electrically controlled, the door handle rotates around the shaft, so that one end of the door handle is tilted up for the user to grab.

[0003] The assembly structure between the handle shaft and the handle base and between the shaft and the handle of the hidden car door handle is not designed with an anti-drop structure. The assembly method is to directly insert the shaft into the shaft mounting hole in the handle frame and the shaft mounting hole on the handle base body. Therefore, after the door handle base assembly is completed, during the transportation of the door handle from the supplier to the OEM, there is a risk of the handle shaft being dislocated or partially dislocated due to shaking and bumping during the logistics process. This results in the need to inspect and repair the handle shaft before final assembly after the door handle arrives at the OEM, which costs manpower costs and repair time.

[0004] In response to this situation, technicians have tried to reduce the fitting clearance between the shaft and the connecting hole to make the connection strength of the shaft stronger and less likely to fall out, or to directly lock the shaft in the connecting hole before leaving the factory. However, other problems will arise: If the shaft is directly thickened to reduce the clearance between it and the connecting hole to tighten it, under high temperature and high humidity conditions, the nylon material in the base and handle absorbs water and swells, and the shaft holes on the base and handle become smaller. At this time, when the handle is rotated, there will be a slow rotation speed, risk of jamming and risk of abnormal noise when rotating; if the shaft is directly locked in the connecting hole before leaving the factory, during the handle assembly process, for example, when the handle base assembly is tested for single product gap difference in the subsequent link or when the face difference is tested after being installed in the car door, if gap face difference or out-of-tolerance problems occur, the shaft needs to be pulled out and the handle needs to be reassembled to improve the gap face difference problem. Therefore, the shaft needs to be taken out for reassembly. If the shaft is directly locked in the connecting hole before leaving the factory and cannot be taken out, it is not conducive to product repair. Therefore, it is necessary to improve the structure of the current hidden car door handle, add an anti-drop design to prevent it from falling out during transportation, and facilitate the disassembly and repair of the shaft. Utility Model Content

[0005] The purpose of the utility model is to overcome the problem that the shaft of the existing hidden car door handle is in the form of a movable plug-in connection, which leads to the problem that the shaft is easy to fall out during transportation, and to provide a hidden car door handle and a door handle assembly thereof. The utility model is convenient for disassembly and assembly of the shaft, and can also prevent the shaft from falling out, so as to avoid the risk of the shaft of the hidden car door handle falling out during transportation, thereby saving the labor cost and repair time of checking the shaft position after the product arrives at the main engine factory.

[0006] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0007] A hidden car door handle comprises a base for connecting to a car door, a handle connected to the base, and a rotating shaft respectively passing through the base and the handle, wherein the handle can rotate relative to the base around the axis of the rotating shaft, and further comprises a limit block detachably connected to the base, wherein the limit block is used to prevent the rotating shaft from escaping from the base.

[0008] The utility model provides a limit block detachably connected to the base to prevent the rotating shaft from coming out of the base. During the transportation from the factory, the limit block can play a role of limiting and preventing coming out, thereby preventing the risk of the rotating shaft coming out or partially coming out due to shaking and bumping in the logistics process, so that the door handle can maintain its structure and performance after long-distance transportation to the main engine factory, and does not need to be reassembled and repaired. During the assembly of the door handle, if problems such as gap face difference or out-of-tolerance occur, the rotating shaft can be released by removing the limit block from the base, so that the rotating shaft can be pulled out and the handle can be reassembled to improve the gap face difference and other problems. In this way, the utility model well solves the problem that the hidden door handle rotating shaft is easy to come out during transportation or bumpy conditions, and at the same time can meet the demand for disassembly and assembly of the rotating shaft for product repair.

[0009] Furthermore, a storage cavity for accommodating the handle is provided on the base. The embedded storage cavity can store the handle therein, so that the handle can be hidden on the vehicle door.

[0010] Furthermore, the hidden car door handle also includes a sealing gasket that is detachably connected to the outer periphery of the storage cavity and is used to be closely attached to the outer surface of the door. The sealing gasket can prevent rainwater and other liquids from flowing into the connection gap between the base of the hidden door handle and the door along the door, thereby reducing the corrosion of internal electronic components or parts by rainwater. It should be noted that the assembly order of the sealing gasket is to first assemble the handle and the base together with the rotating shaft, and then assemble the two-color sealing gasket to the outer periphery of the storage cavity and seal it with the base.

[0011] As a preferred solution, one end of the limit block is connected to the base, and the other end of the limit block is provided with an anti-detachment hook, which abuts against the end surface of the rotating shaft.

[0012] Furthermore, a guide portion is provided at one section of the anti-slip hook, and an abutment portion is provided at the other end of the anti-slip hook. The abutment portion abuts against the end surface of the rotating shaft after the rotating shaft is inserted into the base. Therefore, the anti-slip hook can easily enter the connecting hole along the guide portion of the anti-slip hook when the rotating shaft is inserted into the base, and the abutment portion abuts to prevent the rotating shaft from falling out.

[0013] Furthermore, a convex buckle is provided at one end of the limit block connected to the base, and a slot for the convex buckle to engage is provided on the base. The detachable connection is performed by detachable connection of the slot and the convex buckle, and the convex buckle and the slot have an interference fit, and the connection method is simple and effective.

[0014] Furthermore, the number of the limit blocks includes two groups, and the two groups of limit blocks are symmetrically distributed along the axis of the rotating shaft. Providing two groups of limit blocks can make the anti-slip hook symmetrically abut the end face of the rotating shaft, and the force is more evenly applied, so as to prevent one limit block from failing to limit when a large collision or bump occurs. Providing two groups of limit blocks has a more stable and effective limiting effect.

[0015] As another preferred solution, one end of the limit block is connected to the sealing pad, and the other end of the limit block extends above the rotating shaft and is used to prevent the rotating shaft from falling out of the base. The limit block is arranged on the sealing pad, and the limit block can be used to prevent the rotating shaft from falling out and release the limit by disassembling and assembling the sealing pad;

[0016] On the other hand, the limit block and the sealing gasket can be integrally injection molded, or a clamping hole for installing the limit block can be opened on the sealing gasket, and a buckle can be provided at one end of the limit block connected to the rotating shaft.

[0017] Furthermore, an avoidance groove is provided on the periphery of the storage cavity, the shaft passes through the avoidance groove and the handle in the storage cavity, and the other end of the limit block extends into the avoidance groove and blocks the top of the shaft. Providing the avoidance groove on the periphery of the storage cavity can reduce the gap between the sealing gasket and the base, so that the sealing gasket can better fit closely with the periphery of the storage cavity, thereby achieving a better sealing effect.

[0018] Furthermore, the limit block is an elastic member. It should be noted that when the limit block is an elastic member, when the rotating shaft needs to be released or pulled out, an external force can be applied to the limit block to cause it to deform, thereby avoiding the pull-out path of the rotating shaft, so that it is not necessary to remove the limit block to release the interference position between the limit block and the rotating shaft, which can further improve the efficiency and convenience of removing the rotating shaft.

[0019] A door handle assembly includes the above-mentioned hidden automobile door handle, and also includes an actuator arranged on a base, and a transmission mechanism respectively connected to the output end of the actuator and the handle. Under the drive of the actuator, the transmission mechanism drives the handle to rotate around the axis of the rotating shaft.

[0020] It should be noted that the transmission mechanism includes but is not limited to cams, swing arms, and a cable mechanism for controlling the handle door lock to unlock. The actuator is an electronically controlled actuator that can drive the transmission mechanism to work in conjunction under the control of the vehicle computer, thereby driving the handle to rotate around the axis of the rotating shaft, so that one end of the handle swings out of the accommodating cavity in the base, making it easier for the operator to hold it.

[0021] Compared with the prior art, the beneficial effects of the utility model are:

[0022] (1) The utility model provides a limit block detachably connected to the base to prevent the shaft from falling out of the base. During the transportation process from the factory, the limit block can play a role in limiting and preventing the shaft from falling out, thereby preventing the shaft from falling out or partially falling out due to shaking and bumping during the logistics process. This allows the door handle to maintain its structure and performance after long-distance transportation to the main engine factory, without the need for reassembly and overhaul.

[0023] (2) The limit block of the utility model is detachably connected to the base. After the limit block is removed, the rotating shaft can be released, so that the rotating shaft can be pulled out and the handle can be reassembled to improve the gap and surface difference problems, thereby meeting the need to disassemble and assemble the rotating shaft when the product is returned for repair.
