[0033] In the description of the present invention, "plurality" means two or more.

[0034] Hereinafter, a vehicle door outer handle 1 according to an embodiment of the present invention will be described with reference to the accompanying drawings.

[0035] like Figures 1-4 As shown, the vehicle door outer handle 1 according to an embodiment of the present invention includes a base 100 and a handle grip 200 .

[0036] The base 100 is provided with a hand latch groove 110 and is suitable for being installed on a vehicle door. The handle 200 is rotatably installed on the base 100 between a closed position and an open position. When the handle 200 is in the closed position, the outer surface of the handle 200 does not protrude from the outer surface of the vehicle door and covers the hand latch groove 110. When the handle 200 is rotated from the closed position to the open position by rotating into the hand latch groove 110, the handle 200 does not protrude from the outer surface of the vehicle door and the hand latch groove 110 is exposed.

[0037] Among them, the handle 200 is in the closed position, which means that the car door is in a locked state and the car door cannot be opened at this time; the handle 200 is in the open position, which means that the car door is in an unlocked state and the user can open the car door by pulling the handle 200; the handle 200 is rotated from the closed position to the open position, which can control the car door from a locked state to an unlocked state.

[0038] According to an embodiment of the present invention, the outer door handle 1 is provided with a hand groove 110 on the base 100 and is suitable for being installed on the vehicle door. The handle 200 is rotatably installed on the base 100 between a closed position and an open position. There is a vehicle door space inside the vehicle door for installing the outer door handle 1. The hand groove 110 can reserve an operating space for the user to operate the handle 200. The user can extend his hand into the hand groove 110 of the base 100 to touch the handle 200 and control the opening and closing of the vehicle door. In addition, the base 100 can separate the hand groove 110 from other components inside the vehicle door to prevent the user from touching other components while touching the handle 200, and prevent dust and liquid from entering the vehicle door space from the hand groove 110 when the hand groove 110 is exposed, which is beneficial to ensuring the cleanliness of the vehicle door space and reducing the chance of corrosion of parts in the vehicle door space.

[0039] In addition, when the handle 200 is in the closed position, the outer surface of the handle 200 does not protrude from the outer surface of the vehicle door and covers the hand latch groove 110. When the handle 200 is rotated from the closed position to the open position by rotating into the hand latch groove 110, the handle 200 does not protrude from the outer surface of the vehicle door and exposes the hand latch groove 110.

[0040] When the handle 200 is in the closed position, the handle 200 is in a hidden state, and the handle 200 and the vehicle door look more like a whole. When the user looks at the vehicle door, the handle 200 does not appear abrupt, and the outer surface of the vehicle door is more beautiful and neat. When the handle 200 is rotated from the closed position to the open position, the handle 200 rotates toward the inside of the vehicle door. At this time, the handle 200 still does not protrude from the outer surface of the vehicle door, thereby preventing the handle 200 from being exposed to the outside of the vehicle door, so that the handle 200 is in a hidden state regardless of whether it is in the closed state, the open state, or any position between the closed and open states. The vehicle door is neater in the locked state or the unlocked state, and there is no problem of the handle 200 colliding with or being scratched by objects outside the vehicle. The use safety is high, and when the temperature is low, even if the outer surface of the vehicle door is cold and frosted, since the handle 200 rotates toward the inside of the vehicle, it will not be affected by the frost on the outer surface of the vehicle door, so that the rotation of the handle 200 is still smooth when the temperature is low.

[0041] Furthermore, when the handle 200 is rotated from the closed position to the open position, the hand grip groove 110 is exposed, allowing the user to insert their hand into the hand grip groove 110 and pull the handle 200 to open the door, providing a better user experience. Furthermore, when the handle 200 is in either the closed or open position, it does not protrude from the outer surface of the door. This prevents the handle 200 from increasing the vehicle's wind resistance while driving, thereby reducing the vehicle's driving resistance and lowering its energy consumption.

[0042] In this way, the vehicle door exterior handle 1 according to the embodiment of the present invention can be completely hidden, and has the advantages of neat appearance, high safety in use, easy rotation and low wind resistance.

[0043] In some specific embodiments of the present invention, Figure 1 As shown, when the handle 200 is in the closed position, the outer surface of the handle 200 is flush with the outer surface of the vehicle door.

[0044] In this way, the handle 200 can be hidden when in the closed position, the integrity of the outer surface of the door is higher, the entire vehicle is more beautiful, and the joint between the handle 200 and the door remains flush and not easy to accumulate dust, making the outer surface of the door more tidy.

[0045] In some specific embodiments of the present invention, Figure 2 and Figure 4 As shown, a portion of the door covers the hand groove 110, another portion of the door covers the hand groove 110 when the handle 200 is in the closed position, and a portion of the door covers the hand groove 110 when the handle 200 is in the open position.

[0046] For example, the side of the base 100 facing away from the passenger compartment is open. When the handle 200 is in the closed position and the vehicle door is in place, the open portion of the base 100 is covered to seal the hand latch groove 110. When the handle 200 is in the open position, the base 100 is partially open to connect the hand latch groove 110 to the outside world. In addition, the outer and inner contours of the cross section of the base 100 are both arc-shaped, which not only ensures that the thickness of the groove wall of the hand latch groove 110 is uniform, but also reduces the material, weight and cost of the base 100 while ensuring that the human hand has sufficient operating space. In addition, the base 100 is subjected to uniform force and is less prone to stress concentration.

[0047] In other words, the cross-sectional area of ​​the hand latch groove 110 is larger than the cross-sectional area of ​​the handle 200, which makes it easier for the handle 200 to rotate within the hand latch groove 110 so that the handle 200 can switch between an open position and a closed position. Moreover, when the handle 200 is in the closed position, the user's hand can be inserted into a portion of the hand latch groove 110 covered by the door. The hand latch groove 110 can reserve a larger operating space for the user to operate the handle 200, making the operation more convenient.

[0048] In some specific embodiments of the present invention, Figure 2 and Figure 3 As shown, the handle 200 is provided with a rotating shaft 210 , and the handle 200 is rotatably mounted on the base 100 via the rotating shaft 210 . The rotating shaft 210 is located at the lower edge of the handle 200 when it is in the closed position.

[0049] Specifically, the rotating shaft 210 can extend in the horizontal direction, and the two ends of the rotating shaft 210 can extend out of the front and rear sides of the handle 200. The front and rear sides of the base 100 can be provided with rotating shaft holes, and the two ends of the rotating shaft 210 are respectively matched with the rotating shaft holes. In this way, through the cooperation of the rotating shaft 210 and the rotating shaft hole, the handle 200 can be rotated relative to the base 100, and the rotation structure is simple and easy to implement. Moreover, the rotating shaft 210 is small in size and does not occupy a large space when arranged on the car door, and it is more convenient to arrange.

[0050] In addition, since most people are naturally right-handed and the palm of their right hand is usually extended to the left or downward, rotating the handle 200 with its lower edge as the rotation axis is more in line with the human body's force exertion habits and is convenient for users to use.

[0051] Furthermore, if Figure 3 and Figure 4 As shown, the exterior door handle 1 also includes a driving device, which is suitable for being connected to the door lock and to the handle 200. When the door lock is unlocked, the driving device drives the handle 200 to an intermediate position between the open position and the closed position. When the handle 200 is in the intermediate position, the hand groove 110 is fully exposed.

[0052] In other words, when the handle 200 is rotated from the closed position to the open position, it will first pass through the middle position. When the handle 200 is in the middle position, the car door is in an unlocked state. The user can open the car door by pressing the handle 200 with his hand and pulling it toward the outside of the car. When the user does not press the handle 200 to the open position, the car door is still in a closed state. In this way, the car door can be doubly locked to prevent the user from accidentally touching the rear door and opening it directly, which is safer.

[0053] For example, the user can send an unlocking signal through the vehicle's Bluetooth key. After receiving the unlocking signal, the door lock will unlock the door. At this time, the driving device will run and drive the handle 200 to rotate from the closed position to the middle position, and the hand latch groove 110 will be exposed. The user can observe that the door is already in the unlocked state, and then put his hand into the hand latch groove 110 to press and pull the handle 200 to open the door.

[0054] Optionally, the handle 200 is rotated from the closed position to the middle position by rotating 110° to 120° into the hand groove 110, and the handle 200 is rotated from the middle position to the open position by rotating 50° to 60° into the hand groove 110, that is, the handle 200 needs to be rotated 160° to 180° from the closed position to the open position.

[0055] By rotating the handle 200 110° to 120° into the hand groove 110, on the one hand, the hand groove 110 can be fully exposed, making it convenient for the user to put his hand into the hand groove 110 for operation. On the other hand, the handle 200 is in a downward tilted state at this time. After the user puts his hand into the hand groove 110, he can easily press the surface of the handle 200 facing the inside of the car when it is in the middle position, thereby making it convenient for the user to exert force toward the outside of the car to apply force to the car door and open the car door.

[0056] In addition, the handle 200 needs to be rotated 50° to 60° from the middle position to the open position, so that the user can feel the rotation of the handle 200 and thus more intuitively feel the effectiveness of the operation. Moreover, when the handle 200 is in the closed position, the outer surface of the handle 200 is flush with the outer surface of the vehicle door, that is, the handle 200 is in a vertical state. Since the handle 200 needs to be rotated 160° to 180° from the closed position to the open position, that is, when the handle 200 is in the open position, the handle 200 is also close to the vertical state, and it is easier for the finger to exert force after contacting the handle 200, which makes it more convenient for the user to pull the handle 200. Most of the force applied by the user to the handle 200 is used to pull the vehicle door open, which is more labor-saving and energy-saving.

[0057] In some embodiments of the present invention, the driving device is a motor (not shown in the figure), which is installed outside the base 100. The motor is connected to the handle 200 and is suitable for door lock communication. Therefore, after the door lock is opened, a signal can be transmitted to the motor. The motor can control the rotation of the handle 200 according to the unlocking signal, thereby achieving the goal of unlocking the door while rotating the handle 200 to the middle position, further facilitating user operation, and the motor has good locking performance, which can achieve reliable positioning of the handle 200. The motor can also achieve the resetting of the handle 200 from the middle position to the closed position.

[0058] In other embodiments of the present invention, Figure 3 and Figure 4 As shown, the driving device includes a push rod and an unlocking rocker arm 300.

[0059] Specifically, one end of the push rod is suitable for transmission connection with the car door lock, the unlocking rocker arm 300 is transmission connected with the handle 200 and is connected to the other end of the push rod through the unlocking push rod buckle 310. Therefore, when the car door lock is unlocked, the push rod can be driven to move, and the push rod can then drive the unlocking rocker arm 300 to rotate through the unlocking push rod buckle 310. When the unlocking rocker arm 300 rotates, it can also drive the handle 200 to rotate to the middle position, so as to realize the rotation of the handle 200 between the closed position and the middle position.

[0060] For example, the unlocking rocker arm 300 can be connected to the rotating shaft 210 and rotate synchronously with the rotating shaft 210. The rear end of the rotating shaft 210 extends out of the rear end of the base 100. The unlocking rocker arm 300 is connected to the rear end of the rotating shaft 210. The unlocking rocker arm 300 is located outside the hand latch groove 110 of the base 100. The rear end surface of the base 100 can be provided with a limiting portion 900. The limiting portion 900 can limit the rotation angle of the unlocking rocker arm 300 to prevent the unlocking rocker arm 300 from excessive rotation and affecting the normal use of the car door lock.

[0061] Furthermore, when the handle 200 is manually pushed from the middle position to the open position, the rotating shaft 210 drives the unlocking rocker arm 300 to rotate to push the push rod to move, thereby achieving complete unlocking of the door lock. At this time, the door can be rotated relative to the vehicle body to expose the passenger compartment.

[0062] The door lock is used to rotate the handle 200 through the unlocking rocker arm 300, so there is no need to set up other driving mechanisms (such as motors), which reduces the number of parts of the door exterior handle 1, not only reduces costs, but also facilitates the miniaturization and lightweight setting of the door exterior handle 1.

[0063] It should be noted that when the driving device is a motor, the handle 200 is still connected to the unlocking rocker arm 300. In this case, the unlocking rocker arm 300 does not have to perform the function of driving the handle 200 from the closed position to the intermediate position. In addition, the two aforementioned methods of moving the handle 200 from the closed position to the intermediate position can be provided simultaneously. Therefore, if one method fails to work properly, a backup method is provided to open the door. This provides more diverse ways to open the door from outside the vehicle, making it more convenient for users.

[0064] A vehicle door assembly according to an embodiment of the present invention will be described below with reference to the accompanying drawings. The vehicle door assembly includes a vehicle door and an outer door handle 1 according to the above embodiment of the present invention.

[0065] According to the vehicle door assembly of the embodiment of the present invention, by utilizing the vehicle door outer handle 1 of the above embodiment of the present invention, the vehicle door outer handle 1 can be completely hidden, and has the advantages of neat appearance, high safety in use, easy rotation and low wind resistance.

[0066] In some specific embodiments of the present invention, Figures 1-4 As shown, the vehicle door includes a vehicle door outer panel 2 and a vehicle door inner panel. The vehicle door outer panel 2 is installed on the outer side of the vehicle door inner panel, that is, the vehicle door outer panel 2 is installed on the side of the vehicle door inner panel facing away from the passenger compartment. The base 100 is installed on the vehicle door outer panel 2 and is located between the vehicle door outer panel 2 and the vehicle door inner panel. The vehicle door outer panel 2 is provided with a handle opening 400 corresponding to the position of the hand groove 110.

[0067] For example, the door outer panel 2 and the door inner panel can jointly define a door panel space for accommodating the drive device and the door outer handle 1. This not only protects the drive device and the door outer handle 1, but also makes the outer surface of the door assembly cleaner, facilitating the overall disassembly and assembly of the door assembly. In addition, the outer surface of the door outer panel 2 is located on the outside of the vehicle, making it easily accessible to passengers. By providing a handle opening 400 in the door outer panel 2, passengers can easily access the door outer handle 1, making opening the door more convenient and quick.

[0068] Furthermore, if Figure 3 and Figure 4 As shown, the side of the vehicle door outer panel 2 facing the vehicle door inner panel is provided with a first positioning protrusion 500 and a second positioning protrusion 600 spaced apart in the up and down directions, the base 100 is provided with a first fixing ear 700 and a second fixing ear 800, the base 100 is located between the first positioning protrusion 500 and the second positioning protrusion 600, the first fixing ear 700 is fixed to the side of the first positioning protrusion 500 facing the vehicle door inner panel, and the second fixing ear 800 is fixed to the side of the second positioning protrusion 600 facing the vehicle door inner panel.

[0069] For example, the first fixing ear 700 and the first positioning protrusion 500 can be connected by threaded fasteners such as bolts, and the second fixing ear 800 and the second positioning protrusion 600 can be connected by threaded fasteners such as bolts. One of the first fixing ear 700 and the second fixing ear 800 can be multiple, for example, there are two second fixing ears 800 and one first fixing ear 700, and the first fixing ear 700 can be located between the two second fixing ears 800 in the front-to-back direction. In this way, by staggering the first fixing ear 700 and the second fixing ear 800 in the length direction of the base 100, the fixing force applied to the base 100 in its length direction is more uniform, so that the position of the base 100 is more stable.

[0070] In addition, since the first positioning protrusion 500 and the second positioning protrusion 600 both protrude from the inner side of the vehicle door outer panel 2 toward the vehicle door inner panel, by installing the base 100 between the first positioning protrusion 500 and the second positioning protrusion 600, the base 100 can be closer to the inner side of the vehicle door outer panel 2, or even fit into the inner side of the vehicle door outer panel 2. In this way, the size of the base 100 protruding from the inner side of the vehicle door outer panel 2 is smaller, which is conducive to reducing the overall size of the vehicle door outer panel 2 and the base 100 in the left and right directions, thereby improving space utilization.

[0071] In addition, the side of the first positioning protrusion 500 facing the inner door panel and the side of the second positioning protrusion 600 facing the inner door panel can both be flat surfaces, and the first fixing ear 700 and the second fixing ear 800 are both flat plates extending in the up and down directions. In this way, the fitting area between the first fixing ear 700 and the first positioning protrusion 500 is larger, and the fitting area between the second fixing ear 800 and the second positioning protrusion 600 is larger, which is beneficial to improving the connection strength between the base 100 and the outer door panel 2.

[0072] Among them, the distance between the upper edge of the first positioning protrusion 500 and the lower edge of the second positioning protrusion 600 is greater than the distance between the upper edge of the first fixing ear 700 and the lower edge of the second fixing ear 800. In this way, the first fixing ear 700 and the second fixing ear 800 will not protrude from the first positioning protrusion 500 and the second positioning protrusion 600 in the upper and lower directions, and the fixation of the base 100 is more reliable.

[0073] A vehicle according to an embodiment of the present invention will be described below with reference to the accompanying drawings. The vehicle includes the door assembly according to the above-described embodiment of the present invention.

[0074] The vehicle according to the embodiment of the present invention can achieve complete concealment of the outer door handle 1 by utilizing the door assembly of the above embodiment of the present invention, and has the advantages of neat appearance, high safety in use and low wind resistance.
