Description

Technical Field

[0001] The utility model belongs to the technical field of automobile accessories, and in particular relates to an outer door handle structure, a door and a car. Background Art

[0002] With the development of the automobile industry, consumers are pursuing car comfort while also requiring their cars to have good sound quality. The door handle is the first part that consumers touch when opening the door, so the sound state at the moment of opening the door is particularly important for consumers to perceive the quality. A good quality door opening sound can give consumers a sense of safety, comfort, luxury, and heaviness, giving them a good first impression of the car. When the existing door handle is used to open the door, the door handle assembly and the door handle seat assembly bracket collide rigidly, which will produce a large abnormal sound and cause discomfort to consumers. At the same time, long-term rigid collision will also shorten the service life of the door handle seat assembly. Summary of the invention

[0003] The utility model provides a vehicle door outer handle structure, a vehicle door and a vehicle. By using a control rod in cooperation with a buffer block of a vehicle door outer handle base, a rigid collision between a vehicle door outer handle pull assembly and a vehicle door outer handle seat assembly bracket is avoided when the vehicle door is opened, thereby reducing the collision sound, improving the sound quality of the door opening, and extending the service life of the vehicle door outer handle seat assembly.

[0004] The specific contents of the plan are as follows:

[0005] A vehicle door outer handle structure includes a control rod arranged on a vehicle door outer handle seat assembly bracket, the control rod is in rotation-limiting contact with the vehicle door outer handle pull handle assembly, a vehicle door outer handle base buffer block is arranged in an upper hole position of the vehicle door outer handle seat assembly bracket, the vehicle door outer handle base buffer block is located between the control rod and the vehicle door outer handle seat assembly bracket, and the front end of the control rod can touch the vehicle door outer handle base buffer block.

[0006] The outer door handle seat assembly includes an outer door handle seat assembly bracket, a control rod, and an outer door handle base buffer block. The control rod is installed on the outer door handle seat assembly bracket through a pin shaft. The outer door handle pull assembly is connected to the outer door handle seat assembly bracket through a front end hook and a rear end hook provided by itself. The hook and the outer door handle seat assembly bracket are both in rotation limit contact. The rear end hook of the outer door handle pull assembly is in rotation limit contact with the front end of the control rod provided on the outer door handle seat assembly bracket. The outer door handle base buffer block is installed and fixed in the upper hole of the outer door handle seat assembly bracket and is located between the control rod and the outer door handle seat assembly bracket. When the door is not opened, the control rod is located below the outer door handle base buffer block and does not contact each other. When the door is opened, the outer door handle pull assembly pulls the pulling part at the front end of the control rod, so that the pulling part of the control rod rotates around the pin shaft and collides with the outer door handle base buffer block. The buffer block of the base of the outer door handle avoids rigid collision between the outer door handle pull assembly and the outer door handle seat assembly bracket, plays a buffering role, reduces the impact sound caused by the collision, improves the sound quality, and at the same time extends the service life of the outer door handle seat assembly.

[0007] Furthermore, the control rod includes a pin shaft, a control rod sleeve, a torsion spring and a pulling part. The control rod sleeve is sleeved outside the pin shaft, the torsion spring is sleeved outside the pin shaft and supported inside the control rod sleeve, a pulling part is provided at the front end of the control rod sleeve, the pulling part is in rotation limit contact with the handle assembly outside the vehicle door, a door lock pull wire clamping hole is provided at the upper end of the control rod sleeve, and a counterweight block is provided at the rear end.

[0008] The outer door handle assembly is in rotational contact with the pulling part at the front end of the control rod. When the outer door handle is pulled, the outer door handle assembly drives the pulling part of the control rod to rotate around the pin shaft and collide with the buffer block of the base of the outer door handle, thereby avoiding a rigid collision between the outer door handle assembly and the bracket of the outer door handle seat assembly, reducing the impact force on the bracket of the outer door handle seat assembly, extending the service life of the outer door handle seat assembly, and reducing the impact sound, thereby improving the sound quality of opening the door. The door lock cable clamping hole set at the upper end of the control rod jacket also translates with the torsion spring to unlock and open the door. A counterweight block is set at the rear end of the control rod jacket to effectively increase the weight. When the outer door handle assembly is reset, it can effectively improve the vibration of the control rod rebound, and cooperate with the buffer block of the base of the outer door handle to effectively reduce the impact sound.

[0009] Furthermore, the buffer block of the base of the outside door handle is hammer-shaped, including a buffer head and a shaft. The cross-sectional area of ​​the buffer head is larger than the cross-sectional area of ​​the shaft. The buffer block of the base of the outside door handle is fixedly installed in the upper hole position of the outside door handle seat assembly bracket. The shaft portion passes through the upper hole position and is fixedly installed on the upper side of the mounting surface. The diameter of the shaft portion matches the diameter of the upper hole position. The buffer head is limited and fixed on the lower side of the mounting surface and is located above the control rod.

[0010] The buffer block of the base of the outside door handle is fixedly installed in the upper hole of the bracket of the outside door handle seat assembly. The shaft passes through the upper hole and is fixed on the upper side of the installation surface. The diameter of the shaft matches the diameter of the upper hole. The buffer block of the base of the outside door handle is shaped like a hammer as a whole. The cross-sectional area of ​​the buffer head is larger than the cross-sectional area of ​​the shaft. The buffer head is limited and fixed on the lower side of the installation surface. The shape of the buffer head can be various, such as a cube structure, an inverted frustum structure, a spherical structure, etc. When the outside door handle is pulled, the pulling part of the pull control rod of the outside door handle assembly rotates around the pin shaft and hits the buffer head of the base buffer block of the outside door handle. The buffer block of the base of the outside door handle is made of rubber, which is wear-resistant and elastic. The buffering function is mainly played by the buffer head.

[0011] Furthermore, the shape of the buffer head of the buffer block of the base of the outer door handle is a cube structure, and the side length of the buffer head of the cube structure is 3mm to 6mm; or, the shape of the buffer head of the buffer block of the base of the outer door handle is an inverted frustum structure, and the upper end surface diameter of the inverted frustum structure is 3mm to 6mm; or, the shape of the buffer head of the buffer block of the base of the outer door handle is a spherical structure, and the diameter of the buffer head of the spherical structure is 3mm to 6mm.

[0012] The buffer block at the base of the outer door handle plays a buffering role as a buffer head. The shape of the buffer head can be various, such as a cube structure, an inverted truncated cone structure or a spherical structure. If it is a cube structure, the side length of the buffer head is 3mm to 6mm; if it is an inverted truncated cone structure, the diameter of the upper end surface of the buffer head is 3mm to 6mm; if it is a spherical structure, the diameter of the buffer head of the spherical structure is 3mm to 6mm.

[0013] Furthermore, the material of the buffer block at the base of the outer door handle is rubber.

[0014] It is prior art that rubber is used as the material of the buffer block of the base of the outer door handle.

[0015] Furthermore, the material of the buffer block of the base of the outer door handle is NBR or EPDM.

[0016] NBR (Nitrile Butadiene Rubber, Chinese name is nitrile rubber). NBR has high wear resistance and slightly lower elasticity. It is used to make rubber sheets and wear-resistant parts. It is an indispensable elastic material in the automotive industry.

[0017] EPDM (Ethylene-Propylene-Diene Monomer, Chinese name is ethylene propylene diene monomer rubber). The elasticity of EPDM is second only to natural rubber and butadiene rubber, and it can still be maintained at low temperatures. It also has excellent aging resistance and can be widely used in automotive parts, automotive seals and other fields. The buffer block of the base of the outer door handle of the utility model uses NBR or EPDM with a hardness of 60-70 Shore hardness. If the hardness of the material is too low, it will lead to insufficient elasticity and cannot effectively withstand pressure; if the hardness is too high, it will lead to excessive rigidity and cannot effectively absorb impact and pressure. The buffer block of the base of the outer door handle uses NBR or EPDM with a hardness of 60-70 Shore hardness, which has the best buffering effect.

[0018] A vehicle door comprises a vehicle door inner panel, a vehicle door outer panel and the vehicle door outer handle structure, wherein the vehicle door outer handle structure is fixed to the vehicle door outer panel by screw connection and clamping connection.

[0019] A car comprises the car door.

[0020] Compared with the prior art, the utility model has the following beneficial effects:

[0021] 1. The control lever of the utility model is provided with a counterweight block, which can effectively increase the weight and effectively improve the vibration of the control lever rebound. Cooperating with the buffer block of the base of the outer door handle, it can effectively reduce the impact sound when the outer door handle assembly is reset.

[0022] 2. The buffer block of the base of the outer door handle of the utility model is installed in the upper hole of the bracket of the outer door handle seat assembly. When the car door is opened, the outer door handle pull assembly pulls the control rod to hit the buffer block of the base of the outer door handle. The buffer block of the base of the outer door handle plays a buffering role. The impact force is much smaller than that of directly hitting the bracket of the outer door handle seat assembly, and the impact sound caused is also reduced accordingly, thereby reducing the echo of the impact sound inside the car door and improving the sound quality when opening the door.

[0023] 3. The buffer block of the base of the outer door handle of the utility model is made of NBR or EPDM with a hardness of 60-70 Shore hardness, has good wear resistance and appropriate elasticity, and plays an optimal buffering role. It can avoid rigid collision during long-term use, effectively reduce the impact sound, and extend the service life of the outer door handle seat assembly. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] Combine the following Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 The embodiments of the present application are described in detail.

[0042] Embodiment 1:

[0043] A door handle structure, see Figure 1 , Figure 2 , Figure 5 As shown, it includes a control rod 2 arranged on the vehicle exterior door handle seat assembly bracket 1, the control rod 2 is in rotationally limited contact with the vehicle exterior door handle pull assembly 3, the vehicle exterior door handle base buffer block 4 is arranged in the upper hole position of the vehicle exterior door handle seat assembly bracket 1, the vehicle exterior door handle base buffer block 4 is located between the control rod 2 and the vehicle exterior door handle seat assembly bracket 1, and the front end of the control rod 2 can touch the vehicle exterior door handle base buffer block 4.

[0044] See Figure 3 As shown, the control rod 2 includes a pin 2-1, a control rod sleeve 2-2, a torsion spring 2-3 and a pulling portion 2-4. The control rod sleeve 2-2 is sleeved outside the pin 2-1, the torsion spring 2-3 is sleeved outside the pin 2-1 and supported in the control rod sleeve 2-2, a pulling portion 2-4 is provided at the front end of the control rod sleeve 2-2, and the pulling portion 2-4 is in rotation-limiting contact with the outer door handle assembly 3, a door lock pull wire clamping hole 2-2-1 is provided at the upper end of the control rod sleeve 2-2, and a counterweight block 2-2-2 is provided at the rear end.

[0045] See Figure 4As shown, the buffer block 4 of the base of the outer door handle is hammer-shaped, including a buffer head 4-1 and a shaft 4-2. The cross-sectional area of ​​the buffer head 4-1 is larger than the cross-sectional area of ​​the shaft 4-2. The buffer block 4 of the base of the outer door handle is fixedly installed in the upper hole of the outer door handle seat assembly bracket 1. The shaft 4-2 passes through the upper hole and is fixedly installed on the upper side of the mounting surface. The diameter of the shaft 4-2 matches the diameter of the upper hole. The buffer head 4-1 is limited and fixed on the lower side of the mounting surface and is located above the control rod 2.

[0046] The buffer head of the buffer block of the door outer handle base is in the shape of a cube structure, and the side length of the buffer head of the cube structure is 3mm to 6mm.

[0047] The material of the door outer handle base buffer block 4 is rubber.

[0048] The material of the door outer handle base buffer block 4 is NBR or EPDM.

[0049] The realization process of the buffering effect of the utility model is as follows:

[0050] The vehicle door outer handle seat assembly includes a vehicle door outer handle seat assembly bracket 1, a control rod 2, and a vehicle door outer handle base buffer block 4. The front end hook 3-1 and the rear end hook 3-2 of the vehicle door outer handle handle assembly are rotationally limited and contacted on the vehicle door outer handle seat assembly bracket 1, so that it can be limited and rotated. Specifically, the rear end hook 3-2 of the vehicle door outer handle handle assembly is connected to the pulling part 2-4 at the front end of the control rod 2, and the control rod 2 is installed on the vehicle door outer handle seat assembly bracket 1 through the shaft pin 2-1. When the vehicle door is opened, the vehicle door outer handle handle assembly is pulled, and the rear end hook 3-2 of the vehicle door outer handle handle assembly pulls the pulling part 2-4 of the control rod 2 to drive the torsion spring 2-3 to twist around the pin shaft 2-1, so that the pulling part 2-4 hits the vehicle door outer handle base buffer block 4 installed in the upper hole of the vehicle door outer handle seat assembly bracket 1. The hole 2-2-1 for the clamping wire set at the upper end of the control rod 2 also moves horizontally, and the wire will be stretched at this time to unlock and open the door. A counterweight block 2-2-2 is set at the rear end of the control rod 2 to increase the weight and effectively improve the vibration of the control rod rebound. It cooperates with the buffer block of the base of the outer door handle to effectively reduce the impact sound when the outer door handle handle assembly is reset. In summary, the setting of the buffer block 4 of the base of the outer door handle avoids direct rigid collision between the outer door handle handle assembly and the bracket 1 of the outer door handle seat assembly, plays a buffering role, reduces the impact sound, improves the quality of the door opening sound, and extends the service life of the outer door handle seat assembly.

[0051] By comparing the stress state and deflection change of the vehicle door outer handle seat assembly bracket 1 without and with the utility model installed, the effectiveness of the buffering effect of the utility model is proved:

[0052] 1. Without the buffer block of the door outer handle base, when the door outer handle assembly 3 is pulled to hit the door outer handle seat assembly bracket 1, the stress state and deflection changes of the door outer handle seat assembly bracket 1 are as follows:

[0053] See Figure 8 As shown, ACB are three points in the outer door handle base assembly bracket 1, L is the length of the outer door handle base assembly bracket 1, and Fd represents the dynamic load.

[0054] Solving the internal force formula X1δ using a hyperstatic structure in material mechanics 11 +Δ 1F =0 for calculation, where X1 represents internal force, δ11 and Δ1F represent two parameters involved in solving the canonical equation of a super statically indeterminate structure using the force method, where Δ1F represents the multiplication of the M diagram and the M-pull diagram, and δ11 represents the multiplication of the M-pull diagram and its own diagram, which has no practical meaning. The calculation process is as follows:

[0055]

[0056]

[0057] Among them, E represents the elastic modulus, which is related to the material, I represents the moment of inertia, and W represents the bending section coefficient, which are all related to the cross section of the outer door handle seat assembly bracket 1.

[0058] 2. Install the buffer block 4 of the door outer handle base. When the door outer handle assembly 3 is pulled to hit the door outer handle seat assembly bracket 1, the stress state and deflection changes of the door outer handle seat assembly bracket 1 are as follows:

[0059] See Fig. 9 As shown, ACB are three points in the outer door handle seat assembly bracket 1, L is the length of the outer door handle seat assembly bracket 1, and Fd represents the dynamic load. The internal force formula is calculated by solving the hyperstatic structure of material mechanics:

[0060]

[0061] By comparison, we can get f max1 >f max2 σ max1 >σ max2 That is, after installing the buffer block 4 of the door outer handle base, the deformation caused by pulling the door outer handle pull assembly 3 to impact the door outer handle seat assembly bracket 1 is smaller, and the stress on the door outer handle seat assembly bracket 1 is smaller, which is beneficial to reducing the impact sound generated by pulling the door outer handle pull assembly 3 to impact the door outer handle seat assembly bracket 1, thereby reducing the echo of the sound inside the door, improving the sound quality of opening the door, and extending the life of the door outer handle seat assembly.

[0062] Embodiment 2:

[0063] The shape of the buffer head of the buffer block of the vehicle door outer handle base of the utility model can also be an inverted truncated cone structure, and the diameter of the upper end surface of the buffer head of the inverted truncated cone structure is 3mm to 6mm.

[0064] Embodiment 3:
