Description

Technical Field

[0001] This utility model belongs to the field of automotive parts technology, specifically relating to a semi-concealed car door handle. Background Technology

[0002] With the development of the automotive industry, car door handles, as an important component of vehicles, not only serve the function of opening and closing doors but also directly affect ease of use and the overall aesthetics of the vehicle. Most existing car door handles adopt an exposed structure, which, while meeting basic opening and closing requirements, still has some shortcomings in long-term use. For example, traditional car door handles lack effective sealing measures when installed with the door sheet metal, making it easy for rainwater and dust to enter the door interior, causing electrical control components to become damp or mechanical parts to rust, thus affecting their service life.

[0003] In addition, some door handles rely on a simple pivot structure for pulling and resetting, which has poor cushioning performance. When the handle returns to its original position, it is prone to direct collision with the base, generating significant noise and accelerating the wear of parts. Furthermore, the operating buttons in traditional door handles have an uncontrollable range of motion, and after frequent use, the buttons are prone to positional shifts or jamming, affecting the triggering stability of the electronic switches.

[0004] In addition, existing car door handles generally do not have a properly optimized reset mechanism. Some products rely solely on the force of a single spring to achieve reset. When the handle or button is used under complex working conditions, it is common for the reset to be untimely or incomplete, which reduces the reliability of the door opening and the user experience. Utility Model Content

[0005] In view of the problems existing in the prior art, the purpose of this utility model is to provide a semi-concealed car door handle, which has a reasonable structure, good sealing performance, buffering function, and can ensure stable reset of the handle and button.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A semi-concealed door handle includes a base assembly mounted on a door sheet metal, with a handle rotatably connected to the base assembly;

[0008] The back of the base assembly is symmetrically and fixedly connected with bushings;

[0009] Connecting blocks are symmetrically fixed to the back of the handle;

[0010] A pin is inserted between the bushing and the connecting block, and a return spring is fitted on the pin. The return spring allows the handle to automatically reset under the action of elastic force.

[0011] A through groove is provided on the handle, and a button is provided in the through groove. The button is rotatably connected to the handle, and a pin arm is provided on the back of the button. A return spring is provided between the two pin arms, and the return spring can make the button automatically return to its original position under the action of elastic force.

[0012] Furthermore, a sealing gasket is provided on the back of the base assembly, and the sealing gasket is located between the base assembly and the door sheet metal.

[0013] Furthermore, a pin hole is provided through the top side of the connecting block, and the pin shaft passes through the pin hole.

[0014] Furthermore, a spring limiting groove is provided on the back of the connecting block, and the two ends of the return spring are inserted into the guide spring limiting groove.

[0015] Furthermore, a cushioning pad is inserted into the base assembly, and the cushioning pad is located between the handle and the base assembly.

[0016] Furthermore, one end of the buffer pad is fixedly connected to a plug post.

[0017] Furthermore, a pressure post is provided on the back of the button, and a switch component is provided on the base assembly, with the pressure post corresponding to the switch component.

[0018] Furthermore, the inner ends of the through groove are provided with limiting hooks, and the button is located between the two limiting hooks. The limiting hooks are used to limit the range of motion of the button.

[0019] Furthermore, the handle is provided with a hand-holding groove for accommodating fingers used to open the handle.

[0020] Compared with the prior art, the beneficial effects of this utility model are:

[0021] This invention creates an effective seal at the structural joint by setting a sealing gasket between the base assembly and the door sheet metal, thereby preventing rainwater and dust from entering. This solves the problem of electrical components getting damp or mechanical parts corroding due to the lack of sealing measures in existing door handles, and improves the protective performance and service life of the door handle.

[0022] This invention adds a buffer pad between the handle and the base assembly, and the buffer pad is firmly fixed by the plug post. This effectively absorbs the impact force when the handle returns to its original position, and avoids direct collision between the handle and the base assembly. This solves the problems of noise and accelerated wear of parts in existing car door handles during the reset process, thereby ensuring the stability and durability of the car door handle.

[0023] This invention features a through groove inside the handle, with limiting hooks at both ends of the groove. The limiting hooks constrain the movement range of the button, which is held in its initial position by a reset spring. The button also works with the switch component via a contact pin to achieve reliable output of the electronic control signal. This solves the problem in the prior art where buttons tend to shift, jam, or become unresponsive after long-term use, ensuring the stability and reliability of the electronic control switch.

[0024] This invention solves the problem of existing car door handles relying on a single spring, which easily leads to untimely or incomplete reset, by setting a spring limiting groove on the back of the connecting block, and forming a reasonable cooperation with the pin shaft. This improves the reliability of car door opening and the convenience of user operation. Attached Figure Description

[0040] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0041] Example 1:

[0042] See Figure 1-5 A semi-concealed car door handle includes a base assembly 2 mounted on the door sheet metal, with a handle 1 rotatably connected to the base assembly 2; bushings 6 are symmetrically fixedly connected to the back of the base assembly 2 to provide stable rotational support for a pin 5; connecting blocks 7 are symmetrically fixedly connected to the back of the handle 1, and the connecting blocks 7 are installed in conjunction with the pin 5 through pin holes 104; a pin 5 is inserted between the bushings 6 and the connecting blocks 7, and a return spring 4 is sleeved on the pin 5. The return spring 4 allows the handle 1 to automatically return to its original position under the action of elastic force, thereby preventing... The lack of a reset mechanism causes the handle 1 to remain in a non-initial position, resulting in abnormal door opening. A through groove 102 is provided through the handle 1, and a button 3 is provided in the through groove 102. The button 3 is rotatably connected to the handle 1. A pin arm 32 is provided on the back of the button 3, and a reset spring 33 is provided between the two pin arms 32. The reset spring 33 can make the button 3 automatically reset under the action of elasticity, thereby ensuring that the switch component 10 can be reliably triggered and avoiding the inability of the electric lock to open normally due to the button 3 being stuck or not resetting in time.

[0043] See Figure 1-2 A sealing gasket 8 is provided on the back of the base assembly 2. The sealing gasket 8 is located between the base assembly 2 and the door sheet metal to form a sealing barrier at the structural joint. The sealing gasket 8 can effectively prevent rainwater and dust from entering the interior of the door, thereby reducing the failure of electronic control components due to moisture. The use of the sealing gasket 8 further improves the protective performance and service life of the door handle.

[0044] See Figure 1-3 A pin hole 104 is provided on the top side of the connecting block 7, and the pin 5 passes through the pin hole 104. The pin hole 104 ensures that the pin 5 can be stably engaged with the connecting block 7 and provides a reliable fulcrum for the rotation of the handle 1. This structure can avoid loosening and noise problems caused by inaccurate positioning during frequent opening and closing of the car door.

[0045] See Figure 1-4The back of the connecting block 7 is provided with a spring limiting groove 105, and the two ends of the return spring 4 are inserted into the spring limiting groove 105. The spring limiting groove 105 is used to fix the position of the return spring 4 to prevent the return spring 4 from falling off or shifting after long-term use. With the cooperation of the spring limiting groove 105, the handle 1 can quickly return to its original position after being released, thereby improving the reliability and safety of the door opening.

[0046] See Figure 2-5 A buffer pad 9 is inserted into the base assembly 2, and the buffer pad 9 is located between the handle 1 and the base assembly 2. The buffer pad 9 can absorb part of the impact force when the handle 1 returns to its original position, so as to prevent the handle 1 from directly colliding with the base assembly 2. The setting of the buffer pad 9 not only reduces the noise during the return process, but also effectively delays the wear of parts and solves the problem of insufficient return life of the door handle in the prior art.

[0047] See Figure 5 One end of the buffer pad 9 is fixedly connected to a plug post 91, which is used to firmly position the buffer pad 9 on the base assembly 2. The fixing method of the plug post 91 ensures the stability of the buffer pad 9 during long-term use and avoids shock absorption failure caused by the loosening of the buffer component.

[0048] See Figure 2-4 The back of button 3 is provided with a pressing post 31, and the base assembly 2 is provided with a switch component 10. The pressing post 31 corresponds to the switch component 10. When button 3 is pressed, the pressing post 31 can accurately press the switch component 10, thereby outputting a control signal to realize the opening or closing of the door electric lock. The cooperation between the pressing post 31 and the switch component 10 avoids the situation of insensitive or malfunctioning electric triggering, and improves the safety of door opening.

[0049] See Figure 3-4 Limiting claws 103 are provided at both ends of the inner side of the through groove 102. The button 3 is located between the two limiting claws 103. The limiting claws 103 are used to limit the range of motion of the button 3. The limiting claws 103 can prevent the button 3 from being excessively offset during operation, thereby avoiding damage to the switch component 10 due to uneven force. This design improves the stability and durability of the button 3.

[0050] See Figure 1-3 The handle 1 is provided with a hand groove 101, which is used to place the fingers of the handle 1 to open it. Through the hand groove 101, the user can operate the handle 1 more conveniently, thereby realizing the smooth opening of the car door. The hand groove 101 not only improves the human-computer interaction performance of the door handle, but also optimizes the overall comfort and convenience of operation.

[0051] Example 2:

[0052] See Figure 1-5 In this embodiment, a semi-concealed door handle includes a base assembly 2 mounted on the door sheet metal. The base assembly 2 is fixed to the door sheet metal with screws. A bushing 6 is symmetrically fixed to the back of the base assembly 2. The bushing 6 has a precision-machined round hole inside to ensure the rotational flexibility and stability of the pin 5. A connecting block 7 is symmetrically fixed to the back of the handle 1. A pin hole 104 is provided through the top side of the connecting block 7. The pin 5 passes through the pin hole 104 and is installed in cooperation with the bushing 6, so that the handle 1 can rotate around the pin 5. A return spring 4 is sleeved on the pin 5. The two ends of the return spring 4 are engaged in the spring limiting groove 105 on the back of the connecting block 7. The spring limiting groove 105 is used to limit and support the return spring 4 to ensure that the return spring 4 will not shift during long-term vibration or repeated use.

[0053] A through groove 102 is formed on the upper surface of the handle 1, and a button 3 is installed in the through groove 102. The button 3 is rotatably connected to the handle 1 via a pivot. Symmetrical pin arms 32 are arranged on the back of the button 3, and a return spring 33 is installed between the two pin arms 32. The return spring 33 is used to ensure that the button 3 returns to its initial position after being released. Limiting claws 103 are arranged opposite each other at both ends of the through groove 102. The limiting claws 103 are used to limit the range of motion of the button 3, thereby preventing the button 3 from excessively swinging and causing misalignment between the contact post 31 and the switch component 10. A contact post 31 is provided on the back of the button 3, corresponding to the switch component 10 on the base assembly 2. When the user presses the button 3, the contact post 31 can directly press against the switch component 10, realizing the output of an electrical signal, thereby driving the electric lock of the door to unlock or lock.

[0054] A sealing gasket 8, made of aging-resistant rubber, is located on the back of the base assembly 2. It is situated between the base assembly 2 and the door sheet metal, effectively preventing rainwater and dust from entering the door interior and preventing malfunctions in the electronic lock or corrosion of components due to moisture or dust accumulation. A buffer pad 9, made of high-polymer elastic material, is located between the base assembly 2 and the handle 1. One end of the buffer pad 9 is fixedly connected to a connector 91, which is inserted into a slot in the base assembly 2 for secure installation. The buffer pad 9 absorbs impact when the handle 1 returns to its original position, preventing direct hard collisions between the handle 1 and the base assembly 2, thereby reducing noise and extending the service life of components.

[0055] During use, the user places their finger into the handle groove 101 on the handle 1 and pulls the handle 1 outward, causing it to rotate around the pin 5, which in turn deforms the return spring 4. When the handle 1 reaches the set angle, the switch component 10 is triggered, and the door's electric lock unlocks. When the user releases the handle 1, the return spring 4 releases its elasticity, pushing the handle 1 to automatically return to its initial position. At the same time, the buffer pad 9 absorbs the impact force during the return, ensuring a smooth return process. If the user needs to operate the door electrically, they only need to press the button 3. The contact pin 31 will press against the switch component 10, triggering an electrical signal to complete the door control function. The button 3 can automatically return to its original position under the action of the return spring 33, thus ensuring that the door's electric lock is always in a stable state.

[0056] The structure and operation of this embodiment can solve the problems of insufficient sealing, untimely reset, lack of buffering and button jamming in existing car door handles during use, thereby improving the protective performance, reliability and service life of car door handles.

[0057] The working principle of this utility model is as follows:

[0058] During installation, the base assembly 2 of this semi-concealed door handle is fixed to the door sheet metal, and a sealing gasket 8 is installed on the back to form a seal between the door sheet metal and the base assembly 2, preventing rainwater and dust from entering the door interior. The handle 1 is rotatably connected between the bushing 6 and the connecting block 7 of the base assembly 2 via a pin 5. A return spring 4 is sleeved on the pin 5, and both ends of the return spring 4 are engaged in the spring limiting grooves 105 of the connecting block 7. When the user pulls the handle 1, the handle 1 can rotate around the pin 5, and after release, it returns to its initial position under the action of the return spring 4.

[0059] During use, the user's fingers can be inserted into the handle groove 101 on the handle 1 for easy pulling operation. To prevent the handle 1 from directly contacting the base assembly 2, a buffer pad 9 is installed on the base assembly 2. The buffer pad 9 is fixed by the plug post 91, which can effectively absorb the impact force when the handle 1 returns to its original position, thereby extending its service life.

[0060] A through groove 102 is provided through the surface of the handle 1. Limiting claws 103 are symmetrically arranged at both ends of the inner side of the through groove 102 to limit the range of motion of the button 3. The button 3 is rotatably mounted on the handle 1. A pin arm 32 is provided on its back, and a return spring 33 is installed between the two pin arms 32 to automatically return the button 3 to its original position after operation. A pressing post 31 is also provided on the back of the button 3. When the button 3 is pressed, the pressing post 31 presses against the switch component 10 on the base assembly 2, thereby outputting an electrical signal to drive the electric lock of the vehicle door to open or close.

[0061] During operation, the user pulls the handle 1 through the handle groove 101, causing the pin 5 to rotate and triggering the switch component 10 to complete the unlocking action; at the same time, the button 3 can be electrically triggered through the contact pin 31. After pulling is completed or the button is released, the return spring 4 and the reset spring 33 can respectively restore the handle 1 and the button 3 to their initial state, ensuring the stability and reliability of the door handle.

[0062] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
