[0037] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model. In addition, it should be understood that the specific implementation methods described herein are only used to illustrate and explain the utility model, and are not used to limit the utility model. In the utility model, unless otherwise stated, the directional words used, such as "upper" and "lower", generally refer to the upper and lower parts of the device in actual use or working state, specifically the drawing direction in the accompanying drawings; while "inside" and "outside" refer to the outline of the device.

[0038] Combine the following Figures 1 to 6 The vehicle of the present application is described.

[0039] Reference Figures 1 to 3 , Figure 1 is a schematic structural diagram of a vehicle (partial structure) provided by an embodiment of the utility model, Figure 2 yes Figure 1 The cross-sectional view at AA is shown in FIG. Figure 3 yes Figure 1 The cross-sectional schematic diagram at BB is shown. The vehicle includes a vehicle body 11 and a detection unit, a telescopic unit 12 is arranged outside the vehicle body 11 and extends along the height direction of the vehicle body 11, the telescopic unit 12 can be telescoped along its axial direction, and the telescopic unit 12 has a connecting section 121 and a mounting section 122 arranged at intervals along its axial direction, the connecting section 121 is connected to the top of the vehicle body 11, the mounting section 122 is provided with a mounting groove 1221, and the detection unit is installed in the mounting groove 1221, and the detection unit is used to identify the environmental parameters around the vehicle body 11.

[0040] In an embodiment of the utility model, the detection unit can identify environmental parameters around the vehicle body 11, such as temperature, humidity, wind speed, obstacles, etc. This enhanced environmental perception capability enables the vehicle to respond more intelligently to changes in the surrounding environment, thereby improving driving safety and comfort. The design of the telescopic portion 12 allows the detection unit to be retracted axially as needed. This adaptability enables the vehicle to adapt to different driving environments and scenarios, such as urban roads, highways, off-road, etc. When the detection unit is not needed, the telescopic portion 12 can be retracted to reduce the protruding portion outside the vehicle, thereby reducing wind resistance and visual interference. This has a positive impact on improving the fuel economy of the vehicle, reducing noise and reducing carbon emissions. Since the detection unit can be installed in the mounting groove 1221 of the telescopic portion 12, the portion of the detection unit protruding from the telescopic portion 12 can be reduced, and wind resistance can be reduced to a certain extent. Improve driving safety and enhance user experience.

[0041] It should be noted that the detection unit includes at least one of a camera, a laser radar and a millimeter-wave radar. The camera can capture rich color and texture information, which is suitable for target classification and segmentation. The laser radar can accurately measure distance and has high resolution. The millimeter-wave radar accurately perceives speed and distance and is not easily affected by bad weather. When the detection unit includes a camera, a laser radar and a millimeter-wave radar at the same time, since the camera can identify the color and texture characteristics of the target, the laser radar and the millimeter-wave radar can provide information such as the location and speed of the target. Combining the data of these sensors, fast and accurate identification and tracking of the target can be achieved. In addition, due to the different working principles and characteristics of different sensors, when one of the sensors fails or is interfered with, the other sensors can continue to work to ensure the overall performance of the vehicle detection system.

[0042] Of course, in other embodiments, the detection unit may also include other sensors, which is not limited in the present application. In addition, different sensor combinations and configurations may be selected according to specific application scenarios and requirements.

[0043] Reference Figures 4 to 6 , Figure 4 is a three-dimensional schematic diagram of the telescopic part provided by an embodiment of the utility model, Figure 5 yes Figure 4 The local enlarged schematic diagram of point C is shown. Figure 6 yes Figure 4The front view of the telescopic part (another angle) shown. In one embodiment, a plurality of mounting grooves 1221 are provided, and the plurality of mounting grooves 1221 are arranged at intervals along the axial direction of the telescopic part 12 and / or the circumferential direction of the telescopic part 12. In this way, a plurality of detection parts can be installed on the telescopic part 12, thereby realizing all-round and multi-angle detection of the surrounding environment of the vehicle body 11. This design can cover a wider detection range and improve the accuracy and reliability of the detection. Multiple detection parts can work at the same time to perform real-time detection of different environmental parameters and improve the detection efficiency. The mounting grooves 1221 are arranged at intervals along the axial and circumferential direction of the telescopic part 12, and the telescopic part 12 is installed accordingly. This design can ensure that the distribution of the detection parts on the telescopic part 12 is more uniform, avoiding local detection blind spots. In addition, through the coordinated work of multiple detection parts, comprehensive monitoring of the surrounding environment of the vehicle body 11 can be achieved. This helps to detect potential dangerous situations in a timely manner and improve the safety and reliability of driving.

[0044] It should be noted that the number and position of the installation slots 1221 can be adjusted as needed, and this application does not limit this.

[0045] Reference Figure 5 In one embodiment, along the axial direction of the telescopic portion 12, the cross-sectional area of ​​the telescopic portion 12 is first increased and then decreased along the length direction of the vehicle body 11, so that the telescopic portion 12 can form a streamlined appearance. The streamlined design helps air flow through the telescopic portion 12 more smoothly, reducing the resistance and turbulence of air flow, thereby reducing wind resistance. Reducing wind resistance not only means that the vehicle encounters less resistance during driving, but also means that the vehicle needs to consume less energy. This helps to improve the energy efficiency of the vehicle.

[0046] Specifically, there are many ways to achieve that the cross-sectional area of ​​the telescopic portion 12 along the axial direction of the telescopic portion 12 is first increased and then decreased along the length direction of the vehicle body 11. For example, Figures 3 to 5In one embodiment, the telescopic portion 12 includes a plurality of sleeves 123 that are sequentially sleeved. Thus, the structure in which the plurality of sleeves 123 are sequentially sleeved allows the telescopic portion 12 to have a certain telescopic ability in the axial direction. In addition, the structure in which the plurality of sleeves 123 are sequentially sleeved makes the assembly and disassembly of the telescopic portion 12 relatively simple. When maintenance or replacement is required, a certain sleeve 123 can be disassembled separately without disassembling the entire telescopic portion 12, thereby improving the convenience of maintenance. Each sleeve 123 has a first side surface 1231, a second side surface 1232, a third side surface 1233 and a fourth side surface 1234 which are connected in sequence, the first side surface 1231 and the third side surface 1233 are arranged opposite to each other, and the second side surface 1232 and the fourth side surface 1234 are opposite to each other, wherein the intersection line of the first side surface 1231 and the second side surface 1232 and the intersection line of the third side surface 1233 and the fourth side surface 1234 are located in a plane extending along the length direction of the vehicle body 11, so that the structure is simple and easy to process, and the wind resistance of the telescopic portion 12 can be reduced to a certain extent.

[0047] Reference Figure 5 In one embodiment, the intersection of the first side surface 1231 and the fourth side surface 1234 is arranged in an arc transition. In this way, the setting of the arc transition makes the first side surface 1231 and the fourth side surface 1234 smoother at the intersection, reduces the stress concentration phenomenon caused by the intersection of right angles or acute angles, thereby improving the stability and durability of the telescopic part 12. In addition, the wind resistance can be further reduced. The setting of the arc transition makes the overall appearance of the telescopic part 12 smoother and rounder, and improves the aesthetics of the telescopic part 12. During the manufacturing and processing process, the setting of the arc transition is easier to achieve than the intersection of right angles or acute angles. This can reduce the difficulty of processing and improve production efficiency and product quality.

[0048] Reference Figure 5 In one embodiment, the intersection of the second side surface 1232 and the third side surface 1233 is set in an arc transition. In this way, the setting of the arc transition makes the second side surface 1232 and the third side surface 1233 smoother at the intersection, reducing the stress concentration phenomenon caused by the intersection of right angles or acute angles, thereby improving the stability and durability of the telescopic part 12. In addition, the wind resistance can be further reduced. The setting of the arc transition makes the overall appearance of the telescopic part 12 smoother and rounder, and improves the aesthetics of the telescopic part 12. During the manufacturing and processing process, the setting of the arc transition is easier to achieve than the intersection of right angles or acute angles. This can reduce the difficulty of processing and improve production efficiency and product quality.

[0049] Reference Figures 1 to 3In one embodiment, the connecting section 121 of the telescopic part 12 is hinged to the top of the vehicle body 11 so that the telescopic part 12 has a working position in a vertical state and a storage position in a horizontal state. The vehicle also includes a driving assembly, which is installed on the vehicle body 11 and is drivingly connected to the telescopic part 12. The driving assembly is used to drive the telescopic part 12 to switch between the working position and the storage position. In this way, when the telescopic part 12 is in the horizontal storage position, the overall size of the vehicle will be reduced, which is convenient for the vehicle to drive in a garage, parking lot or narrow environment. When the vehicle is in an open field and needs to detect environmental parameters, the driving assembly can be used to drive the telescopic movement to the working position, and the length of the telescopic part 12 can be adjusted as needed to ensure that the vehicle can accurately detect the environmental parameters around the vehicle body 11. In addition, the user can easily switch the telescopic part 12 between the working position and the storage position through the driving assembly without manual operation or complicated steps.

[0050] Reference Figures 1 to 3 In one embodiment, the connecting section 121 is provided with an articulated shaft 1211 extending in the horizontal direction, the articulated shaft 1211 is hinged to the top of the vehicle body 11, the driving assembly 14 includes a gear 141, a rack 142 meshing with the gear 141, and a first linear driving portion 143, the gear 141 is sleeved on the articulated shaft 1211, and rotates synchronously with the articulated shaft 1211, the rack 142 is slidably installed on the top of the vehicle body 11, and the first linear driving portion 143 is used to drive the rack 142 to slide, so that the articulated shaft 1211 extends in the horizontal direction and is hinged to the top of the vehicle body 11, ensuring the smooth conversion of the telescopic portion 12 between the vertical and horizontal states, this design has a compact structure and ensures the stability of the connection between the telescopic portion 12 and the vehicle body 11. The transmission method of combining the gear 141 and the rack 142 is used, so that when the first linear drive unit 143 drives the rack 142 to slide, the gear 141 can rotate synchronously and drive the hinge shaft 1211 to rotate, thereby driving the telescopic part 12 to switch between the working position and the storage position. The transmission of the gear 141 and the rack 142 makes the telescopic part 12 switch between the working position and the storage position with high efficiency, high switching accuracy and low noise. By driving the rack 142 to slide by the first linear drive unit 143, the position switching of the telescopic part 12 can be easily achieved, and the operation is simple and convenient.

[0051] It should be noted that there are many types of the first linear drive unit 143. For example, the first linear drive unit 143 may include a linear motor, a gas lever, a hydraulic lever, an electric push rod, etc. Specifically, the present application does not limit this.

[0052] In other embodiments, the driving assembly 14 may further include an articulated rod and a second linear driving part, one end of the articulated rod is articulated with the end of the connecting section 121 away from the vehicle body 11, the second linear driving part has a driving shaft extending in the horizontal direction, the driving shaft has a movable stroke close to or away from the connecting section 121 in the horizontal direction, and the other end of the articulated rod is articulated with the driving shaft, so that when the driving shaft moves away from the connecting section 121, the driving shaft will drive the articulated rod to pull the end of the connecting section 121 away from the vehicle body 11 to rotate toward the vehicle body 11, so that the telescopic part 12 moves to the storage position, and when the driving shaft moves toward the connecting section 121, the driving shaft will drive the articulated rod to push the end of the connecting section 121 away from the vehicle body 11 to rotate away from the vehicle body 11, so that the telescopic part 12 moves to the working position, so as to realize automation and simple operation. In addition, since a stable triangular structure can be formed between the articulated rod, the connecting section 121 and the vehicle body 11, the stability of the connection between the connecting section 121 and the top of the vehicle body 11 is increased to a certain extent.

[0053] It should be noted that there are many types of the second linear drive unit. For example, the second linear drive unit may include a linear motor, a gas lever, a hydraulic lever, an electric push rod, etc. Specifically, the present application does not limit this.

[0054] In one embodiment, when the telescopic portion 12 is in the working position, the distance between the top of the telescopic portion 12 and the ground is H, wherein 2m≤H≤4m. In this way, the telescopic portion 12 is ensured to be within an appropriate range, and it is avoided that the distance between the top of the telescopic portion 12 and the ground is too small, resulting in the detection portion being unable to accurately identify the environmental parameters around the vehicle body 11. At the same time, it is also avoided that the distance between the top of the telescopic portion 12 and the ground is too large, resulting in the structural instability of the telescopic portion 12 or the telescopic portion 12 being easy to collide with other objects, resulting in damage to the telescopic portion 12 or the detection portion.

[0055] In one embodiment, a wire harness channel is provided in the telescopic portion 12, and the wire harness channel is connected to the mounting groove 1221. The wire harness channel is used for the wire harness to pass through, so that the wire harness can be arranged in an orderly manner in the telescopic portion 12, avoiding the disorder of the wire harness and improving the overall neatness of the vehicle. The wire harness channel provides a safe channel, so that the wire harness is effectively protected in the telescopic portion 12. Whether the telescopic portion 12 is in the working position or the storage position, the wire harness will not be directly squeezed or worn by the outside world, thereby extending the service life of the wire harness. When the wire harness needs to be repaired or replaced, it can be conveniently operated through the wire harness channel. Maintenance personnel can easily find and deal with wire harness problems without disassembling too many parts, thereby reducing the difficulty and time cost of maintenance. Since the wire harness channel is connected to the mounting groove 1221, it can adapt to wire harnesses of different lengths and types. This design enables the telescopic portion 12 to be compatible with a variety of different wire harness systems, improving its versatility and adaptability.

[0056] Reference Figure 1 and Figure 2 In one embodiment, the vehicle further includes a support portion 15, one end of the support portion 15 is connected to the vehicle body 11, and the other end is used to support the mounting section 122. In this way, the support portion 15 can provide necessary support for the telescopic portion 12 to prevent the telescopic portion 12 from shaking or displacing due to its own weight or external factors, thereby ensuring that the telescopic portion 12 can remain stable under various road conditions and driving conditions.

[0057] Reference Figure 1 and Figure 2 In order to reduce wind resistance, the support portion 15 and the telescopic portion 12 are arranged at intervals along the length direction of the vehicle body 11, and one end of the support portion 15 is hinged to the top of the vehicle body 11, so that the other end of the support portion 15 has a support position that moves to abut against the mounting section 122 and a laid-down position that moves to contact the top of the vehicle body 11, so that the other end of the support portion 15 is allowed to switch freely between the support position and the laid-down position. When the support portion 15 is in the laid-down position, it can contact the top of the vehicle body 11, thereby reducing the occupied space and facilitating the vehicle to pass through areas with limited space. When the support portion 15 is in the support position, it can abut against the mounting section 122 to provide stable support for the telescopic portion 12.

[0058] It should be noted that the present application does not limit the specific structure of the support portion 15. The support portion 15 can be a support rod or a telescopic rod with a telescopic function. The specific structure of the support portion 15 can be set as needed.

[0059] In addition, in order to improve the supporting stability of the support part 15 for the telescopic part 12, a fixed structure is also arranged between the support part 15 and the mounting section 122. The fixed structure includes a connecting part and a matching part adapted to the connecting part. One of the connecting part and the matching part is arranged on the support part 15, and the other is arranged on the mounting section 122. Through the design of the fixed structure, the support part 15 and the mounting section 122 can be tightly connected, thereby ensuring the stability of the support for the telescopic part 12.

[0060] Specifically, in one embodiment, one of the connecting portion and the matching portion includes a slot, and the other includes a protrusion, so that the connection and separation of the support portion 15 and the mounting section 122 become simple and quick, and the user does not need to use complex tools or perform cumbersome operations, and can complete the installation and removal of the support portion 15 and the mounting section 122 through simple snap-on and unlocking actions, which greatly improves the operating efficiency. The design of the slot and the protrusion has a certain degree of versatility and adjustability, and can adapt to support portions 15 and mounting sections 122 of different models, sizes and structures. This design allows the fixing structure to be widely used in different types of vehicles and equipment, improving its applicability and flexibility.

[0061] Of course, in other embodiments, the fixing structure may also include a magnetic attraction portion and a magnetic attraction matching portion adapted to the magnetic attraction portion, one of the magnetic attraction portion and the magnetic attraction matching portion is provided on the support portion 15, and the other is provided on the mounting section 122, so that the magnetic attraction portion and the magnetic attraction matching portion are automatically aligned and tightly connected by magnetic force, without the need for complicated alignment or plug-in and pull-out actions. This not only simplifies the installation process, but also greatly improves the installation efficiency. The magnetic connection has a strong adsorption force, which can ensure a stable connection between the support portion 15 and the mounting section 122. Even under vibration or external force, the magnetic connection can maintain good stability and reduce the risk of accidental detachment. Compared with traditional connection methods such as screws or welding, the magnetic connection is easier to disassemble and reassemble. This flexibility makes it more convenient when parts need to be adjusted or replaced, and reduces maintenance costs. The magnetic connection can adapt to support portions 15 and mounting sections 122 of different shapes and sizes, and only the shape and size of the magnetic attraction portion and the magnetic attraction matching portion need to be adjusted.

[0062] To reduce wind resistance, refer to Figures 1 to 3 The top of the vehicle body 11 is also provided with a storage groove 111. When the telescopic part 12 is in the storage position, the telescopic part is completely in the storage groove 111. In addition, the drive assembly 14 and the support part 15 in the laid-down position are completely in the storage groove 111. In this way, the telescopic part in the storage position, the drive assembly 14 and the support part 15 in the laid-down position will not protrude from the top of the vehicle body, thereby reducing the wind resistance during the driving of the vehicle, reducing the fuel consumption of the vehicle, and improving the driving efficiency. In addition, this design can also improve the overall aesthetics of the vehicle.
