[0049] The exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0050] The embodiment of the present invention provides a vehicle door, referring to Figure 1 to Figure 4 As shown, the vehicle door 1 may include: a safety protection mechanism 2 and a door panel 3. When the vehicle door 1 is assembled on the vehicle body,

[0051] The safety protection mechanism 2 can at least partially block the door opening of the vehicle;

[0052] When the door panel 3 is closed, it can completely cover the door opening of the vehicle;

[0053] The limit linkage assembly is connected to the safety protection mechanism 2 and the door panel 3 respectively, so that the safety protection mechanism 2 and the door panel 3 can switch between relative displacement and synchronous displacement.

[0054] The structure of the above-mentioned door provided by the embodiment of the present invention includes a safety protection mechanism 2, and the safety protection mechanism 2 and the door panel 3 can switch between relative displacement and synchronous displacement using a limit linkage assembly, which can not only provide safety protection for the driver and passengers and reduce side impact, but also realize a variety of opening and closing state changes, making it convenient for the driver and passengers to get on and off the vehicle, while meeting the needs of maintaining good ventilation and a wide field of vision, thereby improving the riding experience of the driver and passengers. The modular structure also reduces the number of parts and components and reduces the complexity of assembly.

[0055] Figure 1 The figure shows a state where the safety protection mechanism 2 and the door panel 3 are relatively displaced when the door is assembled to the vehicle body;

[0056] Figure 2 The figure shows a state where the vehicle door 1 is assembled on the vehicle body and the safety protection mechanism 2 and the door panel 3 open the door opening.

[0057] Figure 3 The figure shows a state where the vehicle door 1 is assembled on the vehicle body and the safety protection mechanism 2 and the door panel 3 jointly close the door opening.

[0058] During the process of the vehicle door 1 opening the door opening, the safety protection mechanism 2 and the door panel 3 may be opened successively to cause relative displacement; or the safety protection mechanism 2 and the door panel 3 may be opened together to cause synchronous movement.

[0059] During the process of the vehicle door 1 closing the door opening, the safety protection mechanism 2 and the door panel 3 may be closed successively and relatively displaced; or the safety protection mechanism 2 and the door panel 3 may be closed together and synchronously displaced.

[0060] During the process of opening and closing the door 1, the states between the safety protection mechanism 2 and the door panel 3 may be as follows:

[0061] 1. Whether the vehicle door 1 is being opened or closed, the safety protection mechanism 2 and the door panel 3 do not move synchronously, that is, the two can move one after the other to produce relative displacement.

[0062] Second, during the opening and closing process of the door 1, both are linked, that is, they move synchronously, and both produce synchronous displacement;

[0063] 3. During the opening process of the door 1, the two move asynchronously, move one after the other, and produce relative displacement; during the closing process of the door 1, the two move synchronously, and produce synchronous displacement;

[0064] 4. During the closing process of the door 1, the two move synchronously, resulting in synchronous displacement; during the closing process of the door 1, the two move successively, resulting in relative displacement.

[0065] 5. During the opening process of the door 1, the two doors first move asynchronously and then change to synchronous movement; the closing process is similar;

[0066] 6. During the process of opening or closing the door 1, the two first move synchronously and then change to asynchronous movement; the closing process is similar.

[0067] The above situations do not enumerate all possibilities of the vehicle door provided by the embodiment of the present invention in actual use. All structural methods that can realize the above state switching are within the protection scope of the present invention.

[0068] In one embodiment, the safety protection mechanism 2 is a hollow frame that can block the door opening of the vehicle, and the hollow frame is a combination of any one or more of the following structures:

[0069] Planks, strips or rods.

[0070] The above-mentioned limit linkage assembly can make the door panel and the safety protection mechanism produce relative displacement, and play the role of limiting and driving the safety protection mechanism and the door panel to synchronize with each other;

[0071] Reference Figures 6B to 6CAs shown, the safety protection mechanism 2 includes, for example: at least one crossbeam 21;

[0072] The limit linkage assembly includes: a slider 31;

[0073] The slider 31 is fixedly connected to the door panel 3 and is slidably connected to the cross beam 21 . The slider 31 can slide along the cross beam 21 , so that the safety protection mechanism 2 can generate relative displacement with the door panel 3 in a relative sliding manner.

[0074] Furthermore, the slider 31 can abut against the safety protection mechanism 2 in the direction of sliding along the crossbeam 21 , and the safety protection mechanism 2 and the door panel 3 can be displaced synchronously when the slider 31 abuts against the safety protection mechanism 2 .

[0075] Furthermore, the slider 31 includes: a first slider 311 and a second slider 312, the first slider 311 is set at a first position of the door panel 3, and the second slider 312 is set at a second position of the door panel 3, the above-mentioned first position is closer to the front end of the door panel 3 relative to the second position, and the second position is farther away from the front end of the door panel 3 relative to the first position.

[0076] The first slider 311 and the second slider 312 can slide synchronously along the cross beam 21 , so that when the connector 22 at the end of the cross beam 21 is in contact with the second slider 312 , the safety protection mechanism 2 and the door panel 3 can be displaced synchronously.

[0077] When the door is installed on the vehicle body, when the door is opened, if the door panel 3 is pushed by an external force, the first slider 311 and the second slider 312 will slide synchronously along the cross beam 21 toward the rear of the vehicle body, and the door panel 3 and the safety protection mechanism 2 will have relative movement. When the second slider 312 slides and abuts against the connecting head 22 at the end of the cross beam 21, the relative displacement between the door panel 3 and the safety protection mechanism 2 stops, and the two can continue to move synchronously toward the rear of the vehicle body. However, if the safety protection mechanism 2 is pushed by an external force (the door panel 3 is no longer pushed by an external force), the safety protection mechanism 2 can move relative to the door panel 3 again.

[0078] When closing the door, an external force pulls the door panel 3, and since the first slider 311 abuts against the connector 22 at the front end of the beam 21, the safety protection mechanism 2 is driven to move together, and the safety protection mechanism 2 and the door panel 3 are synchronously displaced, and the door is closed at the same time. Alternatively, when closing the door, an external force pulls the safety protection mechanism 2, and the safety protection mechanism 2 moves to the connector 22 at the end of the beam 21 abuts against the second slider 312, thereby driving the door panel 3 to move together, and the safety protection mechanism 2 and the door panel 3 are synchronously displaced, until the safety protection mechanism 2 completely blocks the door opening, and the door panel 3 can continue to have relative displacement with the safety protection mechanism 2 until the door panel 3 completely covers the door opening.

[0079] The connector 22 at the end of the beam 21 has a surface shape that matches the surface of the first slider 311 in the direction for abutting the first slider 311, so that when the two abut, the contact area is as large as possible to ensure stability during linkage.

[0080] Reference Fig. 6A As shown, the hollow frame further includes a longitudinal beam 23 and / or an oblique beam 24 connected to at least one cross beam 21;

[0081] The transverse beams 21 , longitudinal beams 23 and / or diagonal beams 24 in the hollow frame are connected to each other via connecting heads 22 .

[0082] Further, refer to Fig. 6A As shown, the safety protection mechanism 2 includes: an outer frame composed of an upper cross beam 211 and a lower cross beam 212 and a front longitudinal beam 231 and a rear longitudinal beam 232; an oblique beam 24 arranged at a roughly diagonal position along the outer frame; and a middle cross beam 213 located between the upper cross beam 211 and the lower cross beam 212, intersecting with the oblique beam 24 and the rear longitudinal beam 232 respectively.

[0083] The upper cross beam 211 , the lower cross beam 212 , the front longitudinal beam 231 , the rear longitudinal beam 232 , the oblique beam 24 and the middle cross beam 213 may be connected via a connector 22 .

[0084] The number of the first slider 311 and the second slider 312 can be more than one, and the first slider 311 and the second slider 312 can be arranged in pairs on the moving track of the beam 21 .

[0085] Reference Figures 6A to 6C As shown, in order to ensure the effect of position-limiting linkage, multiple second sliders 312 can be respectively arranged at positions on the door panel that are consistent in horizontal direction but different in height direction. The cooperation between the second slider 312 and the connector 22 can ensure the stability of the overall structure when the two move synchronously while exerting the effect of position-limiting linkage.

[0086] Reference Fig. 6A As shown, the upper cross beam 211, the lower cross beam 212, the front longitudinal beam 231, the rear longitudinal beam 232, the oblique beam 24 and the middle cross beam 213 included in the safety protection mechanism 2 can form at least one perspective space. The perspective space allows the driver and passengers to have their left and right fields of vision unobstructed while riding. The wider field of vision not only improves the driving and riding experience, but more importantly, for the driver, it can better avoid the existence of blind spots in the field of vision and better ensure driving safety.

[0087] In order to ensure the structural rigidity of the safety protection mechanism 2 and reduce the overall weight of the vehicle, the safety protection mechanism 2 may be made of carbon fiber material.

[0088] Reference Figure 7As shown, the hollow frame of the safety protection mechanism 2 has a solid frame part and a hollow part, and a vertical projection from the seating reference point of the vehicle (i.e., point R of the human body) to the safety protection mechanism 2 is projected onto the solid frame part.

[0089] Point R is called the "riding reference point" or "seat reference point". Point R is a reference point or seat coordinate point set by the product manufacturer for the seat during the design process. It is used to determine the position of the hinge point between the human torso line and the center of the thigh hip joint when the vehicle is in the normal driving position or the passenger sitting position according to various adjustment methods of the seat such as horizontal, vertical and tilt angle.

[0090] In the embodiment of the present invention, the sitting reference point of the above-mentioned vehicle is vertically projected to the safety protection mechanism 2 and projected onto the solid frame part of the safety protection mechanism 2. It can better provide side safety barriers for various groups of people under different seat adjustment methods and improve the protection performance of the safety protection mechanism.

[0091] In one embodiment, when installed on the vehicle body, the safety protection mechanism 2 is located on the inner side of the door panel 3 ; or the safety protection mechanism 2 is located on the outer side of the door panel 3 .

[0092] In one embodiment, referring to Figure 1-3 , Figure 6C As shown, the limit linkage assembly may further include: a locking structure 4;

[0093] The locking structure 4 includes a first structure and a second structure cooperating with the first structure. The first structure is arranged on the door panel 3, and the second structure is arranged on the safety protection mechanism 2. The first structure and the second structure can automatically cooperate so that the safety protection mechanism 2 and the door panel 3 can switch between mutual locking and unlocking.

[0094] The locking structure 4 can lock or unlock the safety protection mechanism 2 and the door panel 3, so that the safety protection mechanism 2 and the door panel 3 can switch between relative displacement and synchronous displacement.

[0095] In the embodiment of the present invention, the locking structure 4 includes: a mechanical lock and / or an electromagnetic lock.

[0096] In one embodiment, referring to Figure 8 As shown, the locking structure 4 is a mechanical lock, which includes: a lock body 41 and a clamping portion 42 cooperating with the lock body 41 , the lock body 41 is arranged on the door panel 3 , and the clamping portion 42 is arranged on the safety protection mechanism 2 .

[0097] In one embodiment, the locking portion 42 is a slot or a protrusion structure, and the lock body 41 includes an elastic hook and a pressing structure. Releasing the pressing structure can press down the elastic hook so that it can hook the slot or the protrusion, thereby locking the safety protection mechanism 2 and the door panel 3.

[0098] In one embodiment, pressing the pressing structure can lift the elastic hook so that it can be disengaged from the groove, so that the safety protection mechanism 2 and the door panel 3 are unlocked.

[0099] The buckle has a simple structure and a light weight, and is more suitable for vehicles with a lighter body and a lower cost.

[0100] In one embodiment, the locking structure 4 can be an electromagnetic lock, which specifically includes: an electromagnetic body and an iron core part cooperating with the electromagnetic body, the electromagnetic body is arranged on the door panel 3, and the iron core part is arranged on the safety protection mechanism 2.

[0101] The electromagnetic body includes a magnetic attraction structure and a pressing structure. Releasing the pressing structure can energize the magnetic attraction structure to generate magnetic force, so that it can attract the iron core part, so that the safety protection mechanism 2 and the door panel 3 are locked; the pressing structure can stop energizing the magnetic attraction structure and cancel the magnetic force, so that it can detach from the iron core part, so that the safety protection mechanism 2 and the door panel 3 are unlocked.

[0102] The electromagnetic lock may adopt a structure in the prior art, which is not limited here.

[0103] The advantage of electromagnetic locks is that they can generate stronger suction than traditional locks, better lock door panels and safety protection mechanisms, and can realize automatic control of the locking process.

[0104] When the safety protection mechanism 2 and the door panel 3 move to a predetermined relative position (ie, a locking position), the first structure and the second structure automatically cooperate to lock the safety protection mechanism 2 and the door panel 3 .

[0105] Figure 1 to Figure 3 , Figure 6C In the structure shown, the above-mentioned locking position is arranged at the edge position of the safety protection mechanism 2 and the door panel 3. In the embodiment of the present invention, the locking position may include the edge of the safety protection mechanism 2, the edge of the door panel 3, or any intermediate position of the non-edge of the safety protection mechanism 2, any intermediate position of the non-edge of the door panel 3, but it is necessary to ensure that the two are matched in the height direction to facilitate the locking or unlocking operation of the locking mechanism. The present invention does not limit the preset locking position.

[0106] When the door 1 opens the door opening, the safety protection mechanism 2 and the door panel 3 are opened successively and relative displacement occurs; and when the door 1 closes the door opening, the safety protection mechanism 2 and the door panel 3 can be moved synchronously through the limit linkage assembly. This opening and closing method can achieve the effect of fully or partially opening the door panel 3 and closing or partially opening the door opening space of the door because the safety protection mechanism 2 and the door panel 3 can be moved asynchronously during the opening process, providing good ventilation and a wider field of view in the vehicle. When the door 1 is closed, the two are linked through the limit linkage assembly, which can simplify the door closing operation process.

[0107] The door panel 3 can be an integrated structure, which means that the door panel 3 can be formed in one piece from the same material, or can include multiple components, but the components are relatively fixed and cannot be moved. The integrated molding makes the manufacturing easier and the overall structural performance is better.

[0108] In order to obtain a good field of vision, in the embodiment of the present invention, the door panel 3 may be made of a transparent material, such as various glasses, plastics, resins, and the like.

[0109] Preferably, the door panel 3 in the embodiment of the present invention can be made of PC polycarbonate glass, which is light in weight, resistant to high temperatures, highly transparent, has good light transmittance and good impact resistance, which can make the overall weight of the door lighter and safer.

[0110] Of course, in the embodiment of the present invention, the door panel 3 can also be made of a translucent material, so that while satisfying a certain light transmittance inside the vehicle, the privacy inside the vehicle can be improved. The embodiment of the present invention does not limit the specific material used.

[0111] The door panel 3 may also be made of an opaque material.

[0112] Figure 1 to Figure 3 In the embodiment, the door panel 3 is made of transparent material.

[0113] Reference Figure 4 and Figure 5 As shown, the door panel 3 is made of an opaque material.

[0114] The safety protection mechanism 2 can be switched between a first position at least partially blocking the vehicle door opening and a second position completely opening the vehicle door opening.

[0115] The safety protection mechanism 2 is switched between the first position and the second position by sliding and / or rotating relative to the vehicle body.

[0116] The above sliding includes: sliding left and right, sliding up and down relative to the vehicle body;

[0117] The above-mentioned rotation includes: rotating inwards, outwards, and flipping upwards or downwards in the door space.

[0118] In an embodiment of the present invention, the safety protection mechanism 2 can adopt a single sliding method or a single rotation method to switch between two positions. Of course, it can also slide first and then rotate, or rotate first and then slide, to achieve switching from the first position to the second position.

[0119] The above structure makes the operation mode of the safety protection mechanism more flexible.

[0120] The safety protection mechanism 2 is provided with a sliding mechanism matched with the vehicle body, so that the safety protection mechanism 2 can slide forward and backward relative to the vehicle body.

[0121] Specifically, the safety protection mechanism 2 can adopt a sliding groove or sliding rail structure to slide relative to the vehicle body. For example, a sliding groove or sliding rail is set on the vehicle body, and the safety protection mechanism 2 can slide directly on the sliding groove or sliding rail, or by setting a pulley or sliding block on the safety protection mechanism 2, it can slide on the matching sliding groove or sliding rail on the vehicle body, or vice versa, a sliding groove or sliding rail is set on the safety protection mechanism 2, and a matching pulley or sliding block is set on the vehicle body to achieve relative sliding of the two.

[0122] For the door panel 3, similar to the safety protection mechanism 2, it can also adopt sliding and / or rotating methods to produce relative displacement between the vehicle body. The door panel 3 is provided with a sliding mechanism that can be matched with the vehicle body, so that the door panel 3 can slide back and forth relative to the vehicle body.

[0123] Reference Fig. 9 The enlarged image shown is from Fig. 9 It can be seen that the door panel 3 and the bottom of the safety protection mechanism 2 cooperate with the sliding rail 5 on the vehicle body to achieve synchronous movement or sequential movement along the front and rear direction of the vehicle body.

[0124] The safety protection mechanism may be provided with an articulated structure matched with the vehicle body, so that the safety protection mechanism 2 and the door panel 3 can rotate relative to the vehicle body respectively. The articulated structure can refer to the prior art and will not be described in detail here.

[0125] In addition, under the action of the limiting mechanism, the vehicle door can maintain a state in which the protective mechanism and the door panel are staggered at a certain distance. At this time, the protective mechanism can maintain a state in which the door opening is fully or partially opened, and the door panel can maintain a state in which the door opening is fully opened. On the basis of ensuring the safety of the passengers, a good ventilation effect can be achieved. It is suitable for situations where the temperature is high and the vehicle has no air conditioning.

[0126] In one embodiment, the safety protection mechanism 2 is further provided with a first locking mechanism. When the vehicle door 1 is assembled to the vehicle body, the safety protection mechanism 2 can be locked with the vehicle body through the first locking mechanism.

[0127] In one embodiment, the door panel 3 is further provided with a second locking mechanism. When the vehicle door 1 is assembled to the vehicle body, the door panel can be locked with the vehicle body through the second locking mechanism.

[0128] Based on the same inventive concept, an embodiment of the present invention also provides a vehicle using the vehicle door and a method for using the vehicle. Since the principles of the problems solved by the vehicle and the method for using the vehicle are similar to those of the aforementioned vehicle door, the implementation of the vehicle and the method for using the vehicle can refer to the implementation of the aforementioned method, and the repeated parts will not be repeated.

[0129] A vehicle provided by an embodiment of the present invention, referring to Figure 1 to Figure 5 As shown, it comprises: a vehicle body and at least one vehicle door 1 as mentioned above installed on the vehicle body.

[0130] In one embodiment, a matching sliding mechanism is provided between the door panel and the vehicle body, so that the door panel can slide along the front-rear direction of the vehicle body.

[0131] In one embodiment, the safety guard mechanism is slidably connected to the vehicle body.

[0132] In one embodiment, the vehicle body is provided with slide rails or slide grooves adapted to the door panel and the vehicle body, respectively.
