[0038] First refer to Figure 1 , the existing vehicle 1 without B-pillar and opening doors is described. Figure 1 The schematic diagram of the vehicle 1 with no B-pillar and double doors is that the vehicle with no B-pillar and double doors has won the favor of many car enthusiasts and consumers for its convenient entry and exit, large interior space, and unique sense of luxury. Figure 1 As shown in , due to the lack of a B-pillar, the collision strength of the side of the vehicle body cannot be guaranteed, which greatly increases the risk of injury to passengers and the vehicle 1 itself. Therefore, the present invention proposes a new B-pillar-free double-door vehicle 1. Next, the first embodiment of the vehicle 1 of the present invention is introduced.

[0039] like Figure 2 As shown, in order to solve the problem that the side strength of the existing vehicle 1 with no B-pillar and split doors cannot be guaranteed, the vehicle 1 of the present invention is provided with a retractable anti-collision structure 13 on the first door body 11 and the second door body 12 of the split doors. After the doors are closed, the anti-collision structure can enhance the strength of the first door body 11 and the second door body 12. Specifically, as shown in FIG. Figure 2-Figure 10As shown, a first telescopic anti-collision structure 13 is provided on the first door body 11, and the first telescopic anti-collision structure 13 includes a first driving member 131, a first telescopic anti-collision beam 132, a first inner beam 133 and a first outer beam 136. The first driving member 131 is fixedly arranged and connected to the first telescopic anti-collision beam 132, the first telescopic anti-collision beam 132 is fixedly arranged in the first inner beam 133, the first inner beam 133 is slidably arranged in the first outer beam 136, and the first outer beam 136 is fixedly arranged on the anti-collision beam reinforcement plate 112 of the first door body 11, and the corresponding A second telescopic anti-collision structure 14 is provided on the second door body 12, and the second telescopic anti-collision structure 14 includes a second driving member 141, a second telescopic anti-collision beam 142, a second inner beam 143 and a second outer beam 146. The second driving member 141 is fixedly arranged and connected to the second telescopic anti-collision beam 142, the second telescopic anti-collision beam 142 is fixedly arranged in the second inner beam 143, the second inner beam 143 is slidably arranged in the second outer beam 146, and the second outer beam 146 is fixedly arranged on the side door anti-collision beam auxiliary reinforcement plate 122 of the second door body 12.

[0040] When the above embodiment is adopted, after the first door body 11 and the second door body 12 are closed, the first driving member 131 first drives the first telescopic anti-collision beam 132 to move in the direction away from the first driving member 131. Since the first telescopic anti-collision beam 132 is fixedly arranged in the first inner cladding beam 133, and the first inner cladding beam 133 is slidably arranged in the first outer cladding beam 136, and the first outer cladding beam 136 is fixedly arranged on the anti-collision beam reinforcement plate 112 of the first door body 11, the first inner cladding beam 133 will also be driven by the first telescopic anti-collision beam 132 and move together with the first telescopic anti-collision beam 132 in the direction away from the first driving member 131. At the same time, the second driving member 141 will also drive the second telescopic anti-collision beam 142 and drive the second inner cladding beam 143 to move in the direction away from the second driving member 141. Figure 5-Figure 7As shown, the outer diameter of the first telescopic anti-collision beam 132 is smaller than the outer diameter of the second telescopic anti-collision beam 142, the outer diameter of the first inner beam 133 is also smaller than the outer diameter of the second inner beam 143, and a certain space is left between the first telescopic anti-collision beam 132 and the first inner beam 133 and between the second telescopic anti-collision beam 142 and the second inner beam 143. Therefore, when the first telescopic anti-collision beam 132 and the first inner beam 133, the second telescopic anti-collision beam 142 and the second inner beam 143 are respectively driven by the first driving member 131 and the second driving member 141 to move a certain distance, the first telescopic anti-collision beam 132 will be embedded in The second telescopic anti-collision beam 142 is embedded in the space between the first telescopic anti-collision beam 132 and the first inner beam 133, and the first inner beam 133 is also embedded in the space between the second telescopic anti-collision beam 142 and the second inner beam 143, thereby forming an anti-collision layer with a multi-layer overlapping structure. The first outer beam 136 and the second outer beam 146 are respectively fixed on the anti-collision beam reinforcement plate 112 of the first door body 11 and the side door anti-collision beam auxiliary reinforcement plate 122 of the second door body 12, so that the anti-collision layer of the multi-layer overlapping structure provides strength protection against impact.

[0041] The advantage of the above-mentioned setting method is that: through the above-mentioned embodiment, the first retractable anti-collision structure 13 and the second retractable anti-collision structure 14 will only be extended after the first door body 11 and the second door body 12 are closed, and normally when the first door body 11 and the second door body 12 are not closed or the first door body 11 or the second door body 12 is not completely closed, the first retractable anti-collision structure 13 and the second retractable anti-collision structure 14 will not be extended. The retractable structural design makes the anti-collision structure of the vehicle 1 of the present invention not occupy additional space in the vehicle, and improves the user experience as much as possible under the premise of ensuring the side safety of the vehicle 1 without B-pillar opening doors.

[0042] Further reference below Figure 6-Figure 7 , the other contents of the first inner beam 133 and the second inner beam 143 of the present invention are described in detail.

[0043] like Figure 6-Figure 7 As shown, in a possible embodiment, a first driven anti-collision beam 134 is also fixedly provided in the first inner beam 133, and correspondingly, a second driven anti-collision beam 144 is also fixedly provided in the second inner beam 143; when the first telescopic anti-collision beam 132 and the second telescopic anti-collision beam 142 are nested and docked, the first driven anti-collision beam 134 and the second driven anti-collision beam 144 are also nested and docked, and are separated after retraction.

[0044] The advantage of the above-mentioned setting method is that: since the first driven anti-collision beam 134 and the second driven anti-collision beam 144 are respectively arranged on the inner side of the first inner beam 133 and the second inner beam 143, compared with only setting the first telescopic anti-collision beam 132 and the second telescopic anti-collision beam 142, the two more anti-collision beams are set, so that the first telescopic anti-collision structure 13 and the second telescopic anti-collision structure 14 have higher anti-collision strength, thereby better protecting the safety of the occupants and the vehicle 1 when the side of the vehicle 1 without a B-pillar and double-doors is hit.

[0045] like Figure 6-Figure 9 As shown, in a possible embodiment, the first telescopic anti-collision beam 132 is fixedly disposed in the first inner beam 133 through the first support frame 135, and the second telescopic anti-collision beam 142 is fixedly disposed in the second inner beam 143 through the second bracket.

[0046] The advantage of the above arrangement is that, as mentioned above, since a certain space needs to be left between the first telescopic anti-collision beam 132 and the first inner cladding beam 133 and between the second telescopic anti-collision beam 142 and the second inner cladding beam 143, the first telescopic anti-collision beam 132 and the first inner cladding beam 133, and the second telescopic anti-collision beam 142 and the second inner cladding beam 143 are connected respectively by the first support frame 135 and the second support frame 145. Since the first support frame 135 and the second support frame 145 themselves are relatively small in size, the first support frame 135 and the second support frame 145 are arranged at the ends of the first inner cladding beam 133 and the second inner cladding beam 143 without occupying the first inner cladding beam 133. 3 and the second inner beam 143 have too much volume for embedding, so that, while achieving the connection function, it also ensures the volume of the overlapping part of the first telescopic anti-collision structure 13 and the second telescopic anti-collision structure 14, thereby ensuring the anti-collision strength of the overlapping part. In addition, with respect to the first support frame 135 and the second support frame 145, support frames are also provided between the first inner beam 133 and the first driven anti-collision beam 134 and between the second inner beam 143 and the second driven anti-collision beam 144, respectively. It is just that the connection function of the support frame between the driven anti-collision beam and the inner beam is consistent with the function played by the first support frame 135 and the second support frame 145 in this embodiment, which will not be repeated here.

[0047] Continue reading below Figure 6-Figure 9In one possible embodiment, a first connecting sleeve 1321 and a first fastening nut 1322 are provided at the end of the first telescopic anti-collision beam 132, the output end of the first driving member 131 passes through the first connecting sleeve 1321, and the first fastening nut 1322 is provided at the end of the output end. Accordingly, a second connecting sleeve 1421 and a second fastening nut 1422 are provided at the end of the second telescopic anti-collision beam 142, the output end of the second driving member 141 passes through the second connecting sleeve 1421, and the second fastening nut 1422 is provided at the end of the output end.

[0048] The advantage of the above embodiment is that the ends of the output ends of the first driving member 131 and the second driving member 141 are respectively connected to the first telescopic anti-collision beam 132 and the second telescopic anti-collision beam 142 by means of the first connecting sleeve 1321 and the first fastening nut 1322 and the second connecting sleeve 1421 and the second fastening nut 1422. Since the outer diameter of the connecting sleeve is consistent with the inner diameter of the telescopic anti-collision beam, and the inner diameter of the connecting sleeve is consistent with the outer diameter of the output end of the driving member, a tight connection between the driving member and the telescopic anti-collision beam is achieved by setting the connecting sleeve, and then the connection between the output end of the driving member and the connecting sleeve is reinforced by the fastening nut, further ensuring the stability of the connection between the driving member and the telescopic anti-collision beam. On the other hand, compared with setting the output end of the driving member and the telescopic anti-collision beam as an integral molding, the connecting sleeve and the fastening nut are more convenient for disassembly and more conducive to subsequent maintenance work.

[0049] In a possible implementation, the first driving member 131 is a telescopic cylinder, or the first driving member 131 is a combination of a motor and a linear driving structure.

[0050] The advantage of the above embodiment is that no matter whether the first driving member 131 selects a telescopic cylinder or a combination of a motor and a linear drive structure, its ultimate goal is to realize the driving effect on the first telescopic anti-collision structure 13, but the driving cylinder is more likely to directly perform linear driving, and its structure and shape are often fixed and difficult to customize, while the combination of the motor and the linear drive structure can be set into different shapes according to the actual space, so as to adapt to different application scenarios. Technicians in this field can make a choice according to actual needs, or technicians in this field can also choose other common linear drive devices. These changes do not exceed the scope of protection of the invention.

[0051] Different from the first embodiment of the present invention mentioned above, in the second embodiment of the present invention, a first retractable anti-collision structure 13 is only provided on the first double-door type door body 11. The first retractable anti-collision structure 13 includes a first driving member 131 and a first retractable anti-collision beam 132. The first driving member 131 is fixedly arranged and connected to the first retractable anti-collision beam 132. The first retractable anti-collision beam 132 is retractably arranged on the first door body 11. Correspondingly, a groove is provided on the second door body 12 (not shown in the figure). The first retractable anti-collision beam 132 can be embedded in the groove after being extended. Of course, the structure of the first retractable anti-collision structure 13 can also be the same as that of the first embodiment. The structure of the groove can be changed accordingly so that it can be nested to match the first retractable anti-collision structure 13.

[0052] The advantages of the above embodiment are: by only setting the first retractable anti-collision structure 13 on the first door body 11, the retractable anti-collision structure is simplified, which is more conducive to reducing production costs. At the same time, the first retractable anti-collision beam 132 at one end is embedded in the groove at the other end. Since it is relatively easier to embed into the groove, it also reduces the possibility of misalignment caused by errors when the two sides are aligned, thereby making it impossible for the anti-collision structure to perform its function, thereby providing protection for the safety of passengers.

[0053] The present invention further provides a control method for a vehicle 1, wherein the vehicle 1 is the vehicle 1 according to any one of the above embodiments, and the control method includes:

[0054] S01, after receiving a signal to close the door, detecting the status of the first door body 11 and the second door body 12;

[0055] S02 , when it is detected that the first door body 11 and the second door body 12 are completely closed, controlling the extended end of the first retractable anti-collision structure 13 to be connected to the second door body 12 .

[0056] The control method also includes:

[0057] S001, when receiving a signal to open the vehicle door, controlling the extended end of the first retractable anti-collision structure 13 to retract;

[0058] S002: Control the first door 11 and / or the second door 12 to open.

[0059] When adopting the above-mentioned embodiment, when the controller receives a signal to close the vehicle door, it starts to detect the status of the first door body 11 and the second door body 12. If the first door body 11 and the second door body 12 are both in a closed state, the extended end of the first retractable anti-collision structure 13 is controlled to be connected to the second door body 12. If it is detected that there is at least one door body that is not completely closed between the first door body 11 and the second door body 12, the first retractable anti-collision structure 13 is controlled to always be in a retracted state; when the controller receives a signal to open the vehicle door, the extended end of the first retractable anti-collision structure 13 is controlled to retract. After the extended end of the first retractable anti-collision structure 13 is retracted, the first door body 11 and / or the second door body 12 corresponding to the received signal is controlled to open.

[0060] The advantage of the above embodiment is that: since the extended end of the first retractable anti-collision structure 13 is connected to the second door body 12 only when the first door body 11 and the second door body 12 are both in the closed state, from the perspective of safety, regardless of whether the passengers are in the vehicle, this design method can maximize the safety of both people and the vehicle. Specifically, when there are people in the vehicle, adding the first retractable anti-collision structure 13 to the side of the vehicle 1 with no B-pillars can ensure the safety of the passengers to a greater extent. When there is no one in the vehicle but the first door body 11 and the second door body 12 are both in the closed state, When in the closed state, controlling the first retractable anti-collision structure 13 to extend can also protect the side of the vehicle 1 from serious damage due to the lack of a B-pillar, solving the problem that the strength of the side of the existing vehicle 1 with open doors without a B-pillar cannot be guaranteed. On the other hand, from the perspective of convenience, when the first door body 11 or the second door body 12 is not completely closed, the vehicle 1 will not be in a driving state or other situations prone to collision by default. Therefore, controlling the first retractable anti-collision structure 13 not to extend at this time is more conducive to people getting on or off the vehicle, thereby improving the user experience.

[0061] It should be noted that the above-mentioned embodiments are only used to illustrate the principles of the present invention and are not intended to limit the scope of protection of the present invention. Without departing from the principles of the present invention, those skilled in the art can adjust the above-mentioned structure so that the present invention can be applied to more specific application scenarios.

[0062] Those skilled in the art will appreciate that the vehicle 1 also includes some other well-known structures, such as a processor, a controller, and a memory. The memory includes, but is not limited to, random access memory, flash memory, read-only memory, programmable read-only memory, volatile memory, non-volatile memory, serial memory, parallel memory, or registers. The processor includes, but is not limited to, CPLD / FPGA, DSP, ARM processor, MIPS processor, etc. To unnecessarily obscure the embodiments of the present disclosure, these well-known structures are not shown in the drawings.

[0063] Thus far, the technical solutions of the present invention have been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the scope of protection of the present invention is obviously not limited to these specific embodiments. Without departing from the principles of the present invention, those skilled in the art may make equivalent changes or substitutions to the relevant technical features, and the technical solutions after such changes or substitutions will fall within the scope of protection of the present invention.
