Description

Technical Field

[0001] This utility model relates to the field of exterior door handle technology, and more specifically, to an exterior door handle for automobiles that reduces rebound noise. Background Technology

[0002] Car door handles are components installed on the outside of car doors for opening and closing them. Pulling the handle triggers the door lock mechanism to open the door, and pulling the handle closes the door. Car door handles are not only functional components, but also affect the vehicle's appearance and safety.

[0003] Chinese Patent Publication No. CN222310494U discloses a car door handle light. This design involves installing an LED light body inside the handle body, with a sealing cover fitted over the outside. A rotating positioning disc limits the position of the sealing cover, improving the stability of the LED light body during installation. When the LED light body is activated, it emits light both inside and outside the handle body, enhancing the ease of observation of the handle body's position. A telescopic sleeve is installed inside the mounting sleeve. When the handle body is closed, the telescopic rod moves inward, creating an opening between the telescopic sleeve and the telescopic rod, allowing the LED light body to be activated. When the handle body is opened, the telescopic rod's position is reduced, and a spring pushes the telescopic rod into contact with the telescopic sleeve, stopping the LED light body from activating and emitting light, thus reducing resource consumption.

[0004] When a car door handle is opened, it is pulled outwards first. After the door is opened, the user releases the handle, and the handle is reset by an internal torsion spring or pull-back mechanism. However, in the above-mentioned solutions and the handles currently on the market, the handle will collide with the door frame when it rebounds and resets, which will generate noise. The noise means that the door handle has been impacted. As a result, after a long period of use, the plastic fasteners inside the handle are prone to damage, thus reducing the service life.

[0005] Therefore, a car door handle with reduced rebound noise is proposed to address the above problems. Utility Model Content

[0006] 1. Technical problem to be solved:

[0007] This utility model provides a car door handle with reduced rebound noise, which can improve the problems existing in related technologies: when the handle rebounds and resets, the handle will collide with the door frame, thereby generating noise. The noise means that the door handle has been impacted, and the plastic fasteners inside the handle are easily damaged after long-term use.

[0008] 2. Technical Solution:

[0009] To solve the above problems, the present invention adopts the following technical solution.

[0010] This application provides a car door handle for reducing rebound noise, including a handle and a mounting plate, with a car door panel spaced between the handle and the mounting plate. A handle groove is provided at the outer end of the handle. A connecting block two is fixedly connected to one end of the mounting plate. A noise reduction component is provided at the outer end of the connecting block two. A fixed pull head is fixedly installed at the top of the connecting block two. A buffer component is provided at the outer end of the fixed pull head. The noise reduction component includes a movable pressure plate and two sets of rubber balls. The movable pressure plate abuts against the rubber balls. An abutting plate is fixedly connected to the top of the movable pressure plate. The abutting plate movably abuts against the bottom of the handle. When the abutting plate is squeezed by the handle, the movable pressure plate squeezes the rubber balls to achieve slow noise reduction.

[0011] The technical solutions described in this application embodiment have at least the following technical effects:

[0012] When the handle springs back to its original position, the outward-rotating end of the handle first comes into contact with the movable plate. At this time, the movable plate rotates inward to compress the metal spring, initially slowing down the handle. Then, as the handle continues to move downward, it comes into contact with the abutment plate. The abutment plate then drives the movable pressure plate to compress the rubber ball downward. Because the movable plate slows down the handle once, the noise is reduced when the handle hits the abutment plate. The compressed rubber ball then slows down the handle a second time until it comes to a stop, reducing the damage to the door handle from collisions and increasing its service life.

[0013] In some embodiments, the mounting plate is fixedly connected to a connecting block 1 at one end away from the connecting block 2. A through groove is provided inside the connecting block 1. A rotating head and a movable head are fixedly connected to both ends of the handle, respectively. The rotating head is rotatably connected to the inside of the through groove, and the movable head extends through the connecting block 2 to the bottom.

[0014] In some embodiments, the buffer assembly includes a movable plate and a mounting bracket. The fixed pull head has a mounting groove on the side near the handle. The movable plate is rotatably connected to the inner wall of the mounting groove. Guide side plates are fixedly connected to both sides of the movable plate, and the guide side plates abut against the inner sides of the mounting groove.

[0015] In some embodiments, the mounting bracket is fixedly installed inside the fixed pull head, and a metal spring is fixedly connected to the outer end of the mounting bracket. The outer end of the metal spring abuts against the outer end of the movable plate. After one end of the handle abuts against the movable plate, the metal spring is compressed to decelerate the handle.

[0016] In some embodiments, the noise reduction component further includes a mounting housing, with a fixing ring fixedly connected to the outer end of the mounting housing. The mounting housing is fixedly mounted on the outer end of the connecting block two via the fixing ring. The mounting housing has a movable cavity and two buffer cavities inside, which are interconnected. The movable pressure plate is slidably connected to the movable cavity.

[0017] In some embodiments, a fixed vertical rod is fixedly installed inside each of the two buffer cavities, and the rubber ball is movably sleeved on the outer end of the fixed vertical rod, with the rubber ball located inside the buffer cavity.

[0018] In some embodiments, both ends of the movable pressure plate are provided with through holes that match the fixed vertical rod, and the movable pressure plate is slidably connected to the fixed vertical rod through the through holes. Attached Figure Description

[0037] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0038] Please see Figures 1-5 A car door handle for reducing rebound noise includes a handle 1 and a mounting plate 2. A car door panel is spaced between the handle 1 and the mounting plate 2. The handle 1 has a handle groove 10 at its outer end. A connecting block 2 9 is fixedly connected to one end of the mounting plate 2. A noise reduction component 4 is provided at the outer end of the connecting block 2 9. A fixed pull head 3 is fixedly installed at the top of the connecting block 2 9. A buffer component 5 is provided at the outer end of the fixed pull head 3. The noise reduction component 4 includes a movable pressure plate 43 and two sets of rubber balls 46. The movable pressure plate 43 abuts against the rubber balls 46. An abutting plate 44 is fixedly connected to the top of the movable pressure plate 43. The abutting plate 44 is in movable contact with the bottom of the handle 1. The abutting plate 44 is squeezed by the handle 1, which drives the movable pressure plate 43 to squeeze the rubber balls 46 to complete the slow noise reduction.

[0039] The mounting plate 2 is fixedly connected to the connecting block 8 at the end away from the connecting block 9. The connecting block 8 has a through groove 12 inside. The handle 1 is fixedly connected to a rotating head 6 and a movable head 7 at both ends. The rotating head 6 is rotatably connected to the inside of the through groove 12, and the movable head 7 extends through the connecting block 9 to the bottom.

[0040] The handle in this design is a traditional mechanical handle used on the outer door of a car. Mounting plate 2 is installed on the inside of the car door panel, while handle 1 is installed on the outside. Connecting block 1 8 and connecting block 2 9 are fixedly installed at both ends of mounting plate 2, respectively. Connecting blocks 1 8 and 2 9 are installed on the inside of the door panel via their own clips and screws. Rotating head 6 and movable head 7 are fixed on both sides of handle 1. A through groove 12 is formed on the inside of connecting block 1 8, allowing rotating head 6 to be rotatably installed inside the through groove 12. A torsion spring mechanism can also be installed inside the through groove 12 to assist handle 1 in rebounding and resetting. Movable head 7 penetrates the door panel and connecting block 2 9, extending into the interior of the door. Movable head 7 is mainly used to connect with the unlocking mechanism, which can be done by a wire or a linkage. When handle 1 is pulled, movable head 7 pulls the unlocking mechanism, triggering the latch to release and unlock. A handle groove 10 is formed at the outer end of handle 1 for easy gripping by the user.

[0041] A fixed pull head 3 is fixed to the top of the connecting block 2 9. A buffer component 5 is installed on the outside of the fixed pull head 3. The buffer component 5 is mainly used to decelerate the handle 1. A noise reduction component 4 is installed on the top of the connecting block 2 9. The noise reduction component 4 is mainly used to reduce noise and decelerate the handle 1 to a standstill. When the handle 1 springs back to its original position, the outward rotating end of the handle 1 will first abut against the movable plate 51. At this time, the movable plate 51 rotates inward to compress the metal spring 54, which initially decelerates the handle 1. Then, when the handle 1 continues to move downward, it will abut against the abutment plate 44. At this time, the abutment plate 44 will drive the movable pressure plate 43 to compress the rubber ball 46 downward. Since the movable plate 51 decelerates the handle 1 once, the noise can be reduced when the handle 1 hits the abutment plate 44. The compressed rubber ball 46 can decelerate the handle 1 a second time until it stops, reducing the damage to the door handle caused by the collision and improving its service life.

[0042] Please see Figure 4 and Figure 5 The buffer assembly 5 includes a movable plate 51 and a mounting bracket 53. The fixed pull head 3 has a mounting groove 11 on the side near the handle 1. The movable plate 51 is rotatably connected to the inner wall of the mounting groove 11. Guide side plates 52 are fixedly connected to both sides of the movable plate 51, and the guide side plates 52 abut against the inner sides of the mounting groove 11.

[0043] The mounting bracket 53 is fixedly installed inside the fixed pull head 3. A metal spring 54 is fixedly connected to the outer end of the mounting bracket 53. The outer end of the metal spring 54 abuts against the outer end of the movable plate 51. After one end of the handle 1 abuts against the movable plate 51, the metal spring 54 is compressed to decelerate the handle 1.

[0044] In this design, the fixed pull head 3 is hollow inside and fixed to the connecting block 9. An installation groove 11 is opened on the side of the fixed pull head 3 closest to the handle 1. The two sides of the movable plate 51 are rotatably connected to the inner wall of the installation groove 11 through a pivot, so that the movable plate 51 can rotate inside the installation groove 11. Guide side plates 52 are fixed on both sides of the movable plate 51. The guide side plates 52 abut against the inner sides of the installation groove 11. The guide side plates 52 mainly serve as a limit. When the movable plate 51 rotates in the installation groove 11, its guide side plates 52 will always abut against the inner side wall of the installation groove 11, thereby limiting the movable plate 51 and preventing the movable plate 51 from deviating from the rotation trajectory.

[0045] A mounting bracket 53 is fixed inside the fixed pull head 3, and the mounting bracket 53 faces the mounting groove 11. A metal spring 54 is set between the mounting bracket 53 and the movable plate 51. The metal spring 54 is V-shaped. One end of the metal spring 54 is fixed to the inside of the mounting bracket 53 by a rivet, and the other end of the metal spring 54 is in contact with the movable plate 51. In the stationary state, the force of the metal spring 54 can push the movable plate 51 outward, so that the movable plate 51 protrudes from the outer surface of the fixed pull head 3. When the handle 1 rebounds, it will first contact the movable plate 51. At this time, the handle 1 will push the movable plate 51 inward, so that it compresses the metal spring 54. This can consume part of the kinetic energy of the handle 1, so that it can reduce its speed and slow down the speed when the handle 1 contacts the noise reduction component 4.

[0046] Please see Figure 2 and Figure 3 The noise reduction component 4 also includes a mounting housing 41. A fixing ring 42 is fixedly connected to the outer end of the mounting housing 41. The mounting housing 41 is fixedly installed on the outer end of the connecting block 9 through the fixing ring 42. The mounting housing 41 has a movable cavity and two buffer cavities inside. The movable cavity and the two buffer cavities are interconnected. The movable pressure plate 43 is slidably connected to the movable cavity.

[0047] Both buffer chambers are fixedly installed with a fixed vertical rod 45, and a rubber ball 46 is movably sleeved on the outer end of the fixed vertical rod 45, with the rubber ball 46 located inside the buffer chamber.

[0048] Both ends of the movable pressure plate 43 are provided with through holes 47 that match the fixed vertical rod 45. The movable pressure plate 43 is slidably connected to the fixed vertical rod 45 through the through holes 47.

[0049] The noise reduction component 4 in this solution is mainly used to decelerate the handle 1 a second time until it comes to a stop. A fixing ring 42 is fixed to the outer end of the mounting housing 41. The mounting housing 41 can be fixed to the connecting block 9 using screws via the fixing ring 42. Inside the mounting housing 41, there is one movable cavity and two buffer cavities. The movable cavity is located between the two buffer cavities and is interconnected. Inside each of the two buffer cavities, there is a set of rubber balls 46, each set consisting of two or more rubber balls 46. A fixing ring is fixed inside the buffer cavity. The vertical rod 45 and the rubber ball 46 are movably sleeved on the outer end of the fixed vertical rod 45. Inside the movable cavity, the movable pressure plate 43 is slidably installed. Both ends of the movable pressure plate 43 extend into the buffer cavity, and each end has a through hole 47. The movable pressure plate 43 is also slidably connected to the fixed vertical rod 45 through the through hole 47 and abuts against the rubber ball 46. An abutment plate 44 is fixed on the top of the movable pressure plate 43. The abutment plate 44 is located above the mounting housing 41 and connects to the movable pressure plate 43 through the mounting housing 41.

[0050] After the handle 1 rebounds and is decelerated once by the buffer assembly 5, the speed of the handle 1 will decrease. At this time, the handle 1 will come into contact with the abutment plate 44. Since the speed of the handle 1 is relatively slow, the sound when it comes into contact with the abutment plate 44 is relatively small. Then, the abutment plate 44, which is in contact with the handle 1, will drive the movable pressure plate 43 to slide downward. The movable pressure plate 43, which slides downward, will compress the rubber ball 46 in the buffer cavity. Since the rubber ball 46 is relatively soft, it will deform. At this time, the handle 1 can be decelerated a second time until it comes to a stop, and no noise will be generated in this process.

[0051] By combining the noise reduction component 4 and the buffer component 5, the noise generated when the handle 1 rebounds and resets can be reduced, improving the user experience. At the same time, no violent collision will occur during the rebound to a standstill, thereby reducing damage to plastic parts and extending their service life.

[0052] Working principle: When the handle is used to open the door and the handle 1 is released, the rebounding handle 1 will first abut against the movable plate 51. At this time, the handle 1 will push the movable plate 51 inward, compressing the metal spring 54, so that the handle 1 can reduce its speed. After the handle 1 is decelerated by the buffer component 5, the sound when it abuts against the abutment plate 44 is smaller. Then, the abutment plate 44 abutting against the handle 1 will drive the movable pressure plate 43 to slide downward. The sliding movable pressure plate 43 will compress the rubber ball 46 in the buffer cavity. At this time, the handle 1 can be decelerated a second time until it comes to a stop, reducing the generation of noise. At the same time, there will be no violent collision during the rebound to a stop, thereby reducing the damage to the plastic parts and improving their service life.
