Description

Technical Field

[0001] This utility model belongs to the field of automotive door handle technology, specifically, it relates to an automotive door panel handle structure. Background Technology

[0002] Cars have become a common means of transportation in modern life. With the development of automotive technology, the driving experience has gradually improved. As an important component for opening car doors, the structure of car door handles is also particularly important.

[0003] Chinese utility model patent CN215168987U discloses a protective car door handle, including a handle with a groove in the middle of the front and an annular smooth cavity on the outer side of the front. A limit ring is installed inside the annular smooth cavity, with its outer surface contacting the inner wall of the handle. A telescopic ring is fixedly connected to the front of the limit ring, and the telescopic ring can move through the front wall of the handle's inner cavity and is fixedly connected to a bumper plate at the front of the handle. This protective car door handle, through the combined action of a slider, auxiliary plate, rotating plate, working shaft, buffer spring, bumper plate, and limit ring, provides a certain degree of cushioning when subjected to external forces, extending the device's service life and reducing the impact on the car. The combined action of a threaded rod, threaded tube, rotating block, fixing screw, and rubber head makes installation and removal of the handle more convenient.

[0004] The aforementioned existing technology also has the following drawbacks: when the handlebars are impacted, the anti-collision plate can only retract laterally for protection. If the impact force hits the upper and lower edges of the anti-collision plate, the buffering effect is poor and it cannot provide a good protection effect. Utility Model Content

[0005] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0006] To address the problem mentioned in the background art that when the handlebars are impacted, the anti-collision plate can only retract laterally for protection, and if the impact force hits the upper and lower edges of the anti-collision plate, the buffering effect is poor and it cannot provide a good protective effect, the present invention adopts the following technical solution.

[0007] A car door handle structure includes a handle body, an inner groove on the outer wall of the handle body, and a protective component installed inside the inner groove. The protective component can buffer the impact force received by the handle body.

[0008] Preferably, a buffer component is installed between the handle body and the protective component, which can assist the protective component in buffering the impact force.

[0009] Preferably, the protective component includes a crash plate, a mounting plate, a sliding block, a buffer spring, a through hole, a torsion spring shaft, a sliding groove, and a sliding rod. Sliding grooves are provided on both sides of the inner wall of the inner groove, and sliding rods are fixedly connected inside the sliding grooves on both sides. A mounting plate is fixedly connected to the back of the crash plate, and a torsion spring shaft is provided inside the mounting plate. Buffer springs are fixedly connected to both ends of the torsion spring shaft, and a through hole is provided on the buffer spring, which is fitted onto the outer wall of the sliding rod. A buffer spring is fixedly connected to the back of the sliding block, and the buffer spring is fitted onto the outer wall of the sliding rod. When the crash plate impacts, it causes the buffer spring to move towards the door from the outer wall of the sliding rod, compressing the buffer spring.

[0010] Preferably, the edge of the mounting plate is completely flush with the outer wall of the handle body.

[0011] Preferably, the buffer assembly includes a buffer airbag, a connecting tube, an inflatable airbag, and a storage groove. The buffer airbag is detachably connected to the inside of the inner groove. Connecting tubes are fixedly connected to both the upper and lower sides of the buffer airbag. The ends of the connecting tubes on both sides are detachably connected to the inflatable airbag. The mounting plate is provided with an upper and lower opposite storage groove near the outer wall of the buffer airbag. The inflatable airbag is positioned opposite to the storage groove. The buffer airbag stores gas at a certain pressure inside. When the mounting plate moves and squeezes the buffer airbag, the gas inside the buffer airbag enters the interior of the inflatable airbag through the connecting tube, causing the inflatable airbag to expand. The movement of the anti-collision plate causes the inflatable airbag to enter the interior of the storage groove.

[0012] Preferably, the outer wall of the airbag is detachably connected to an inflation check valve, and a pressure sensor is installed inside the airbag. The inflation check valve is connected to an external inflation device to inflate the airbag. The pressure sensor can monitor whether the airbag is leaking in real time and transmits the data to the vehicle's dashboard.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. Through the protective components, when the anti-collision plate is hit from the front, the buffer springs on both sides move towards the door on the outer wall of the sliding rod and compress the buffer springs, thus achieving buffering of the frontal impact. When the upper and lower edges of the anti-collision plate are hit, the mounting plate rotates and the torsion spring of the torsion spring shaft buffers the impact, thereby buffering the impact force on the upper and lower edges of the anti-collision plate and making the protection effect better.

[0014] 2. By ensuring that the edge of the mounting plate fits perfectly against the outer wall of the handle body, the outer wall of the handle body becomes uniform and more aesthetically pleasing.

[0015] 3. Through the set buffer components, when the mounting plate moves and squeezes the buffer airbag, the gas inside the buffer airbag enters the interior of the expansion airbag through the connecting pipe, thereby causing the expansion airbag to expand. As the anti-collision plate moves, the expansion airbag can enter the interior of the storage groove, thereby increasing the buffering force against the impact.

[0016] 4. The airbag can be connected to an external inflation device via the one-way valve to inflate it, thus ensuring that there is enough gas inside the airbag. The pressure sensor can monitor whether the airbag is leaking in real time and transmits the data to the car's dashboard, so that maintenance or inflation can be performed in a timely manner.
