Detailed ways

In order to understand the above objects, features and advantages of the present disclosure more clearly, the solutions of the present disclosure will be further described below. It should be noted that, as long as there is no conflict, the embodiments of the present disclosure and the features in the embodiments can be combined with each other.

Many specific details are set forth in the following description to fully understand the present disclosure, but the present disclosure can also be implemented in other ways different from those described here; obviously, the embodiments in the description are only part of the embodiments of the present disclosure, and Not all examples.

With the more and more comprehensive development of vehicle manufacturing technology, existing vehicles generally have anti-collision parts protruding from the door outer panel on the outside of the door to block external impacts, thereby avoiding paint peeling, dents and other damage to the door sheet metal. . This kind of protection device can be used as a door anti-collision device to withstand a certain impact without causing damage, and the cost of repair or replacement is much lower than repairing the door sheet metal.

The door trim is generally located at the lower part of the door, and the upper area of the door, which is more susceptible to impact, is not protected, and the anti-collision device is not beautiful and affects the overall shape of the vehicle. Some vehicles will be equipped with door active anti-collision devices. That is, when the vehicle opens the door, a soft pad will extend out to cover the outer edge of the door to prevent its own door from hitting the vehicle parked next to it. There are similar products in the automotive after-sales market, which include anti-collision strips installed on the outer edges of car doors. However, this type of anti-collision device cannot prevent other vehicles from hitting their own doors when their doors are opened.

Due to the lack of effective door anti-collision devices, the car door sheet metal is very easy to be hit by other vehicles when the doors are opened, resulting in paint peeling and sheet metal dents. Paint repair is prone to color difference, and sheet metal repair is also prone to surface unevenness. phenomenon, especially the difficulty in repairing aluminum alloy door sheet metal. Generally, the entire door needs to be replaced, and the repair cost is high. If not repaired, the beauty of the car will be seriously affected.

In view of the above defects, this embodiment provides an anti-collision device for a vehicle. By providing an anti-collision structure that can move relative to the outer surface of the vehicle, it is used to realize real-time protection of the outer surface of the vehicle and avoid collision with external vehicles. The surface of this vehicle causes paint peeling and sheet metal dents to occur. Specifically, the detailed structural settings of the anti-collision device are described in the following content:

As shown in Figures 1-9, the embodiment of the present disclosure provides an anti-collision device 1, which is used to be arranged on the outer surface of a vehicle. The anti-collision device 1 includes an anti-collision structure and a fixed bracket 13 connected to the door.

The fixed frame 13 has an accommodating groove, and the notch of the accommodating groove faces the outside of the door 2. The anti-collision structure is arranged in the accommodating groove, and the anti-collision structure is included in the accommodating groove and can extend from the notch to The external movable part 12 of the vehicle door 2 .

In specific implementation, the anti-collision structure of the anti-collision device 1 uses driving force to cause the movable component 12 to protrude from the inside of the accommodating groove, so that it protrudes beyond the position of the vehicle, usually laterally. At this time, the vehicle is usually in a stopped state. When there is a collision near the vehicle, the external impact object first hits the surface of the anti-collision structure, thus preventing the impact object from directly contacting the outer surface of the vehicle and damaging the paint or vehicle sheet metal surface. . When the vehicle is ready to drive, the movable component 12 of the anti-collision structure can be retracted by operating the driving force, thereby preventing the anti-collision structure from being on the outside of the vehicle and affecting the normal driving of the vehicle.

The driving mode of the anti-collision structure can be controlled through the vehicle's control module. For example, the anti-collision structure is electrically connected to the control module of the vehicle, specifically, the movable component 12 is electrically connected to the control module of the vehicle. When the vehicle control module receives the extension signal, it sends a signal to drive the movable component 12 to move. , so that it extends to the outside of the door to form a protective protect the space; when the vehicle control module receives the retract signal, it sends a signal to further drive the movable component 12 to move. At this time, the direction of movement is opposite to the direction of movement when the drive signal receives the extension signal, so that the anti-collision structure can be retracted. The vehicle returns to normal condition.

The vehicle control module can receive signals through the central control system inside the vehicle or through an external vehicle remote control. Or, when the anti-collision device 1 is installed on the car door 2, when the vehicle is in the stalled state and receives the operating status of the door 2 being opened and then closed, the anti-collision device 1 is provided with the sensor through the sensor on the door 2. The application of the inductive anti-collision device 1 by using signals can make the vehicle's operation mode more intelligent.

Of course, in other embodiments, it can also be manually driven. For example, by operating a component on the outer surface of the vehicle that can be connected to the movable component 12 to extend or retract the movable component 12 relative to the vehicle, the anti-collision effect can also be achieved. . When manual driving is adopted, it can be realized through a rocker or a pulley, that is, the rocker or the pulley is connected to the movable part 12, and it can be conveniently installed on the exposed surface of the vehicle to facilitate manual operation by the user. .

To sum up, the anti-collision device 1 and the vehicle provided by this embodiment are provided with a fixing bracket 13 on the door of the vehicle, and an accommodating groove is formed on the door through the fixing bracket 13. Furthermore, an anti-collision device 1 is provided in the accommodating groove. The anti-collision structure allows the movable part 12 of the anti-collision structure to protrude from the door toward the outside of the door. During normal driving, the anti-collision device does not need to protrude from the surface of the vehicle body, so as not to affect the wind resistance and the overall beautiful appearance. In the parking state, the anti-collision device extends out of the anti-collision structure through the movable part 12, making it protrude from the sheet metal of the door 2. When an external entity approaches the vehicle, it will first contact the anti-collision device 1. Instead of directly touching the outer surface of the door 2, it has the function of blocking surrounding vehicles from hitting the own vehicle when the door 2 is opened, and plays a role in protecting the outer surface of the vehicle. At the same time, it also has high flexibility in use. It will not have a major impact on the appearance of the vehicle and can ensure the overall aesthetic effect.

The anti-collision device 1 can be applied not only on the door panel of the vehicle, but also on other locations on the outer surface of the vehicle. In this embodiment, the anti-collision device 1 is applied on the panel of the vehicle door 2 as an example. During actual production and installation, the anti-collision structure can be extended on the panel of the door 2 along the transverse direction of the vehicle. When applied to other locations on the outer surface of the vehicle, the anti-collision device 1 can be adaptively adjusted and installed according to the size of the installation space and the extent of extension required to be protected.

The anti-collision structure further includes an anti-collision piece 11. One end of the movable part 12 is rotationally connected to the inner wall of the accommodation slot. The anti-collision piece 11 is disposed at one end of the movable part 12 close to the slot. Through the rotational connection, the movable component 12 can push the anti-collision member 11 to move in a direction away from the outer surface of the vehicle. In some embodiments, one end of the movable component 12 is connected to the bottom of the accommodating groove, and the bottom of the accommodating groove refers to the inner wall of one side of the accommodating groove relative to the slot opening.

In order to realize the rotational connection between the movable part 12 and the accommodating groove, the movable part 12 is further a rotating link 121. One end of the rotating link 121 is connected to the inner wall of the accommodating slot, and the other end of the rotating link 121 is connected to the anti-collision The member 11 is rotatably connected, so that the anti-collision member 11 is pushed out of the accommodating groove by rotating relative to the inner wall of the accommodating groove.

In this embodiment, a rotating shaft support 132 can be provided at the bottom of the accommodating groove, and a rotating shaft connecting hole is provided on the rotating shaft supporting member 132. Similarly, a rotating shaft connecting hole is provided at one end of the rotating connecting rod 121, so that the rotating shaft can The support member 132 is opposite to the rotation shaft connection hole of the rotation link 121, and has a rotation shaft passing through it to realize the rotation connection between the rotation link 121 and the accommodating groove. Of course, in other embodiments, other rotational connection methods may also be used.

For the end of the rotating link 121 that is connected to the anti-collision piece 11 , the same connection method between the rotating link 121 and the accommodating groove can also be used. In some embodiments, a connecting bracket 111 can be provided on the anti-collision member 11, and a connecting bracket 111 is provided with Rotating shaft connection hole, similarly, a rotating shaft connecting hole is opened at one end of the rotating connecting rod 121, by making the connecting bracket 111 and the rotating shaft connecting hole of the rotating connecting rod 121 face each other, and passing through the rotating shaft, to realize the rotating connecting rod 121 and the anti-collision piece 11 rotational connections. Of course, in other embodiments, other rotational connection methods may also be used.

In this embodiment, a rotational connection is used between the movable component 12 and the fixed frame 13 to realize the movement of the anti-collision member 11 relative to the door 2. Of course, in other embodiments, it can also be realized through other transmission components. The movement of the anti-collision member 11 relative to the vehicle door 2 can also be accomplished by making the movable component 12 have a telescopic structure and the telescopic direction is from the receiving groove toward the outside of the vehicle door 2 . This can also achieve positional movement relative to the vehicle door 2 .

Furthermore, the anti-collision piece 11 can adopt a strip-shaped rod structure, and its edges are chamfered to avoid being too sharp and causing safety hazards. Its extension length can be extended and covered by maximizing the range based on the settings of other components inside the panel of the door 2, so as to ensure the anti-collision effect in as much scope and space as possible. In this embodiment, the extension direction of the rod of the anti-collision member 11 may be set along the length direction of the vehicle.

Usually, the height of the anti-collision member 11 disposed on the door 2 panel in the direction perpendicular to the ground is between 650 mm and 850 mm, and the specific value is determined according to the size of the vehicle body. Its position at the front and rear of the door 2 should also try to cover the extended front and rear range of the door 2. On this basis, a certain distance is generally left from the edge of the opening of the door 2 and the hinge of the door 2 for use inside the door 2. For the layout of other structures, a distance of up to 50mm is usually left. In other embodiments, the beautification design can also be carried out according to the modeling intention to form other shapes or other sizes.

When the anti-collision piece 11 is driven to the extended state by the movable part 12, its distance from the panel of the door 2 is set to no more than 50 mm to meet the specification requirements of the vehicle appearance, and at the same time it will not have an excessive impact on the external shape, so that The overall appearance is flatter. When the anti-collision part 11 is in the retracted state, it may not protrude from the outer surface of the vehicle at all, that is, the outer surface of the anti-collision part 11 is flush with the outer side of the door 2 to make the appearance smooth, but it can also ensure a smooth appearance. , on the basis of the smooth connection between the anti-collision part 11 and the outer panel surface of the vehicle, an appropriate amount of protrusion is formed on the outer surface of the vehicle.

Among them, the anti-collision part 11 can be made of TPO (Thermoplastic polyolefin, referring to thermoplastic polyolefin elastomer) material, which has the advantages of lower density, more energy saving and environmental protection compared to PVC (Polyvinyl chloride, referring to polyvinyl chloride) material. Of course, in other embodiments, other materials can also be used to make the anti-collision part 11, for example, ABS (Acrylonitrile butadiene Styrene copolymers, refers to acrylonitrile-butadiene-styrene copolymers) material can be used to make the anti-collision part 11 with chrome plating and surface treatment. and other materials suitable for automotive exterior decoration.

During assembly, the surface spray color of the anti-collision part 11 is consistent with the surface spray color of the vehicle body, so that the overall appearance is consistent. A textured surface treatment can also be used to make the surface of the anti-collision piece 11 less likely to be damaged after being hit, and to make smaller bumps and scratches more difficult to detect.

Further, when realizing the connection between the anti-collision device 1 and the outer surface of the vehicle, the relative fixation is carried out through the fixing bracket 13. In some embodiments, there is a mounting opening 21 on the outer surface of the vehicle door, and the fixing bracket 13 is provided. 13 is set at the installation port 21. The above-mentioned accommodating groove is formed on the surface of the fixing bracket 13 , and the notch of the accommodating groove is exposed at the installation opening 21 . By opening an installation opening 21 on the outer surface of the vehicle and correspondingly setting the fixing bracket 13 at the installation opening 21, it is convenient for the vehicle door 2 and the anti-collision device 1 to be produced separately and assembled after the production is completed, which greatly reduces the cost. The production and installation difficulties of each component of the vehicle are reduced.

When installing the fixing bracket 13 and the outer panel of the door 2, the fixing bracket 13 and the outer plate of the door 2 are sealedly connected to avoid This prevents dust or rainwater from entering the inside of the door 2 and causing damage to other electrical components arranged inside the door 2 . In some embodiments, a ring 131 can be provided along the edge of the notch of the accommodating groove of the fixing bracket 13 so that the ring 131 fits the inside of the installation opening 21 on the outer surface of the vehicle and is sealed at the joint. deal with. The sealing treatment can be done by bonding the rim 131 to the inside of the vehicle's mounting opening 21, or by riveting, as long as only the mounting slot is exposed from the mounting opening 21.

In addition, in order to further ensure the sealing effect and surface smoothness, the outer contour shape of the anti-collision member 11 can also be set to match the shape of the notch of the accommodating groove.

The fixed frame 13 can be made of TPO or ABS material, and the rotating shaft support 132 and the connecting bracket 111 can be made of TPO or ABS material, or other materials that can ensure the structural strength can be used, and can be made of buckles, welding, gluing, Fix it with the fixing bracket 13 or the anti-collision bar by screws or other means. The material of the rotating connecting rod 121 can be made of PA (Polyamide, referring to nylon), or other materials with good stability to transmit torque.

When arranging the rotating links 121, the number of the rotating links 121 can be set to at least two to ensure the smooth effect of the anti-collision member 11 during movement. Moreover, all the rotating links 121 are arranged along the axial direction of the anti-collision member 11 .
