Description

Technical Field

[0001] This utility model belongs to the field of automotive parts technology, specifically relating to the structure of the injection-molded trim panel on the inner side of a car door. Background Technology

[0002] With the continuous development of science and technology, cars have gradually been introduced to every household. From traditional transportation cars to the present, people are increasingly pursuing aesthetics, especially the interior of the car. Currently, the door panel handle cups of car models are all molded in the Z direction. Due to the limitations of the mold structure, the handle cup gripping area cannot be made into an arc shape. When passengers grip the handle cup to open and close the door, their fingers cannot bend, resulting in poor ergonomics. If the mold direction of the handle cup is changed, the snap structure (clamping structure) connecting the handle cup and the door panel body cannot be molded, which cannot be realized on the mold.

[0003] Currently, there is a type of car interior handle on the market, such as the automotive door trim panel handle cup installation structure proposed in publication number CN205172219U, in which the handle cup gripping area is curved; the handle cup is fixedly connected to the door panel body by screws; the armrest trim panel is snapped to the door panel body by buckles; the handle cup is fixedly connected to the center trim panel by screws; and the switch panel is connected to the handle cup by gantry buckles.

[0004] The existing handle rings can serve many purposes, such as beautifying the interior. However, during installation, the armrest trim and handle ring are fixedly connected by threads. When the armrest trim is placed in the door panel groove, it will block the space inside the groove, making it inconvenient to install the screws. Both installation and disassembly are difficult. Moreover, if the thread is not removed for a long time, the threads may rust and lock, making it inconvenient for later maintenance and replacement, thus having certain limitations. Utility Model Content

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-3 This utility model provides a technical solution: an injection-molded trim panel structure for the inner side of a car door, including a door panel body 3 and a middle trim panel 7. A pull ring 1 is threadedly fixed to one side of the middle trim panel 7. One end of the door panel body 3 is threadedly fixed to the other end of the pull ring 1. One end of the pull ring 1 is provided with an arc surface 2. A pin seat device 4 is fixedly connected to one side of the pull ring 1. An armrest plate 6 is provided on one side of the door panel body 3. A pin post device 5 is slidably sleeved on one side of the armrest plate 6. The pin post device 5 is limited and inserted into the inside of the pin seat device 4. An armrest decorative outer panel 17 is fastened to the outer surface of the armrest plate 6.

[0019] In this embodiment, the handrail 6 and the latch seat device 4 are connected by a latch pin device 5 for limiting and sleeved connection. When the handrail 6 is pulled outward, the latch pin device 4 can be pulled outward under the limiting action of the latch pin device 5, thereby pulling the pull ring 1 to open the door. During installation, the handrail 6 and the latch pin device 5 are placed as a whole inside the door panel body 3. At this time, the latch pin device 5 is slidably sleeved in the groove of the latch seat device 4. Pushing and rotating the latch pin device 5 locks it in place, so that the latch pin device 5 can be limited and sleeved in the latch. The seat device 4 is inserted into the interior to lock the pin seat device 4 and the armrest plate 6. Then, the armrest decorative outer panel 17 is fitted to decorate the armrest plate 6. Similarly, when disassembling, the armrest decorative outer panel 17 is removed in advance, and then the pin post device 5 is pushed inward to rotate, which can release the locking state of the pin post device 5, so that disassembly can be completed quickly. Compared with the traditional threaded fixing, this design method will not cause rust and difficulty in disassembly after long-term disuse. Installation and disassembly are very convenient, the operation is simple, and it is easy for the driver to operate, replace and maintain.

[0020] Specifically, the pin holder device 4 includes a pin base 8, a limiting block 10, an abutment spring 11 and an abutment ring 12, and a pin groove 9 is fixedly opened in the center of the pin base 8.

[0021] In this embodiment, the pin post device 5 can be sleeved inside the pin slot 9 opened in the center of the pin base 8.

[0022] Specifically, a limit stop 10 is fixedly connected to one end of the pin base 8, and a notch 16 is fixedly opened on one side of the limit stop 10.

[0023] In this embodiment, by setting the limiting block 10, the pin device 5 is inserted through the notch 16 and then rotated to abut against the inner side of the limiting block 10, thereby limiting and fixing the pin device 5.

[0024] Specifically, a retaining spring 11 is fixedly connected to the bottom of the inner side of the pin groove 9, and a retaining ring 12 is fixedly connected to one end of the retaining spring 11. A through hole is opened in the center of the retaining ring 12.

[0025] In this embodiment, when the pin device 5 is inserted, it can abut against the abutment ring 12, thereby compressing the pull ring 1. After rotating the pin device 5, it is released. Under the elastic action of the abutment spring 11, the abutment effect of the pin device 5 can be made more secure. When pulled outward, the pin device 5 abuts against the inner side of the limit block 10 and does not act on the abutment spring 11, so it does not affect the abutment effect.

[0026] Specifically, the pin device 5 includes a pin body 13, a rotary knob 14, and a stop 15. The stop 15 is fixedly connected to one end of the pin body 13, and the rotary knob 14 is fixedly connected to the other end of the pin body 13.

[0027] In this embodiment, by pressing the rotary knob 14, the pin body 13 is pushed deeper into the pin groove 9. At this time, the stop block 15 also enters the pin groove 9 through the notch 16. The stop block 15 presses against the abutment ring 12, causing the abutment spring 11 to deform. Then, rotating the rotary knob 14 causes the stop block 15 to be offset from the notch 16. Under the elastic action of the abutment spring 11, the stop block 15 can abut against the inner side of the limiting stop block 10, so that the handrail 6 can be abutted and fixed. During use, the handrail 6 and the pin seat device 4 are connected by the pin device 5 for limiting. When the handrail 6 is pulled outward, under the limiting action of the pin device 5, it can be pulled back. Pulling the outer latch seat 4 will pull the latch ring 1 to open the door. During installation, the handrail plate 6 and the latch post device 5 are placed inside the door panel body 3. At this time, the latch post device 5 is slidably sleeved in the groove of the latch seat device 4. Pushing and rotating the latch post device 5 will lock it, so that the latch post device 5 can be limited and sleeved inside the latch seat device 4, thereby locking the latch seat device 4 and the handrail plate 6. Then, the handrail decorative outer panel 17 is sleeved on to decorate the handrail plate 6. Similarly, when disassembling, the handrail decorative outer panel 17 is removed in advance, and then the latch post device 5 is pushed inward and rotated to release the latch post device 5 from the locked state, so that disassembly can be completed quickly.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
