Description

Technical Field

[0001] This invention relates to the field of vehicle design technology, and in particular to a method for separating and assembling a combined vehicle, and a combined vehicle. Background Technology

[0002] People are becoming increasingly reliant on cars, and the scenarios in which they are used in future life and work are becoming more and more complex. One car may not be able to meet all needs for a family, while purchasing two vehicles is relatively expensive. Furthermore, problems such as parking difficulties, traffic congestion, and energy shortages are becoming increasingly serious. Under the condition of meeting daily use functions, energy-efficient, compact, and economical vehicles are more likely to be favored by users. Summary of the Invention

[0003] The purpose of this invention is to provide a method for separating and assembling a combined vehicle, as well as a combined vehicle, to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a hybrid vehicle, comprising:

[0005] The combined vehicle can be separated into two vehicle body units, each of which can be used as a vehicle for independent driving.

[0006] The two vehicle body units are respectively provided with docking locking mechanisms. When the two vehicle body units are docked to form a combined vehicle, the docking locking mechanisms of the two vehicle body units are docked and locked to combine the two vehicle body units into a combined vehicle.

[0007] The vehicle body unit is provided with drive wheels and support wheels. The drive wheels are used for steering and driving the vehicle body unit, and the support wheels are used for supporting the vehicle body unit.

[0008] Furthermore, it also includes a sealing device and a vacuum pressure pump. The rear frame of the cabin of the vehicle body unit has the sealing device. When the two vehicle body units are docked to form a combined vehicle, the sealing devices of the two vehicle body units dock to form a sealed receiving cavity. The receiving cavity is connected to the vacuum pressure pump, which can remove the air in the receiving cavity to make the receiving cavity a vacuum state.

[0009] Furthermore, it also includes:

[0010] The tailgate has a closed position and an open position. When the tailgate is in the closed position, the tailgate closes the rear frame of the vehicle body unit cabin. When the tailgate is in the open position, the tailgate is located at the top of the vehicle body unit.

[0011] A moving mechanism, which is connected to the vehicle body unit and the tailgate respectively, is used to drive the tailgate to a closed position or an open position.

[0012] Furthermore, the vehicle body unit is provided with a support wheel drive mechanism, which is connected to the support wheel. The support wheel drive mechanism can drive the support wheel to move to a retracted position and a supported position. When the support wheel is in the retracted position, the support wheel is away from the ground. When the support wheel is in the supported position, the support wheel abuts against the ground to support the vehicle body unit.

[0013] Furthermore, the docking locking mechanism is an automatic rotation locking mechanism. The corresponding automatic rotation locking mechanisms of the two vehicle body units can rotate to the locking position to complete interlocking. When docking is a combined vehicle, the docking locking mechanisms of the two vehicle body units dock and lock together, combining the two vehicle body units into a combined vehicle, ensuring that the sealing elements are tightly pressed together.

[0014] Furthermore, it also includes a camera and radar, which can be used to detect the relative positions of the two vehicle body units and assist the two vehicle body units in adjusting their attitude to a position where they are directly opposite each other on the rear frame of the cockpit.

[0015] Furthermore, it also includes an infrared receiver and an infrared transmitter. When the two rear frames of the cockpit are in a facing position, the infrared transmitter emits infrared rays, and the infrared receiver receives the infrared signal to determine the docking status of the two vehicle body units, accurately identify the relative position of the vehicles, and adjust the attitude through the infrared signal to complete the precise docking of the two rear frames of the cockpit.

[0016] Furthermore, it also includes a pressure detection device, which sets a differential pressure threshold. When the differential pressure across the vacuum pressure pump is less than the differential pressure threshold, the vacuum pressure pump starts to work, and when the differential pressure across the vacuum pressure pump is greater than the differential pressure threshold, the vacuum pressure pump stops working.

[0017] On the other hand, a method for separating a combined vehicle is provided, applied to a combined vehicle as described in any of the above claims, comprising:

[0018] The two body units of the combined vehicle receive a signal indicating that it will be separated into two body units.

[0019] Detect whether there are obstacles within a preset distance between the two vehicle units;

[0020] If there is an obstacle, an alarm will be sounded, and the position of the combined vehicle will be adjusted to a preset distance where there is no obstacle.

[0021] If there are no obstacles within the preset distance, a signal is sent to control the support wheel drive mechanism to drive the support wheels to contact the ground and support the vehicle body unit.

[0022] A signal is sent to inflate the cavity with air using a vacuum pressure pump, making the pressure difference inside and outside the cavity the same.

[0023] Send a signal to unlock the automatic locking mechanism;

[0024] A signal is sent to drive the two vehicle body units to separate at a preset distance;

[0025] The two vehicle body units move the tailgate from the open position to the closed position via a moving mechanism.

[0026] Furthermore, a method for assembling a combined vehicle is provided, applicable to any of the combined vehicles described above, comprising:

[0027] The two separated vehicle body units receive a rejoining signal;

[0028] Detect whether the tailgate of the vehicle body unit is in the open or closed position;

[0029] An alarm will sound if the tailgate is closed, prompting the user to open the tailgate.

[0030] If the tailgate is in the open position, determine whether the two vehicle units are in the other's radar detection range.

[0031] If the vehicle is not within the enemy's radar detection range, an alarm will be issued, and the positions of the two vehicle units will be adjusted to the enemy's radar detection range.

[0032] The radar and cameras identify the positions of the two vehicle units and automatically adjust their positions to be basically aligned.

[0033] The fitting position of the two vehicle body units is calibrated, and the relative position of the two vehicle body units is precisely adjusted according to the infrared signal. When the infrared signal determines that the two vehicle body units are in the calibrated fitting position, the automatic locking mechanism locks, and the vacuum pressure pump evacuates the cavity until the preset pressure difference threshold is reached.

[0034] The signal is sent to control the support wheel drive mechanism to move the support wheel to the retracted position.

[0035] Compared with existing technologies, the advantages of this invention are: it can solve the problem of multi-scenario use for users, meeting the needs of family travel as well as the need to use two vehicles simultaneously. When used separately in the front and rear, the vehicle size is smaller, making parking easier, and energy consumption is lower, making it economical and practical. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0047] Please refer to the accompanying drawings in the specification. This invention provides a technical solution: such as... Figure 1 As shown, a hybrid vehicle includes:

[0048] The combined vehicle 100 can be separated into two vehicle body units, each of which can be used as a vehicle for independent driving.

[0049] The two car body units include car body units 110 and 120.

[0050] The docking locking mechanism 200 is provided on the rear frame of the cabin of the two vehicle body units respectively. When the two vehicle body units are docked to form a combined vehicle 100, the docking locking mechanisms 200 corresponding to the two vehicle body units are docked and locked to combine the two vehicle body units into a combined vehicle 100.

[0051] The vehicle body unit is provided with a drive wheel 300 and a support wheel 400. The drive wheel 300 is used for steering and driving the vehicle body unit, and the support wheel 400 is used for supporting the vehicle body unit.

[0052] In the above embodiments, the combined vehicle 100 can be separated into two vehicle body units, each of which can be used as a vehicle for independent driving. Two flip-up wheels are provided at the bottom center of the vehicle; when used as two vehicles, these wheels can serve as support wheels 400 for the rear wheels. The four wheels at the front and rear of the combined vehicle 100 are drive wheels 300, providing steering and driving functions. They have an internal self-balancing system that adjusts the wheel angles according to road conditions and vehicle status to ensure stable vehicle operation.

[0053] Optionally, it also includes a sealing device 500 and a vacuum pressure pump 510, with the sealing device 500 located on the rear frame of the cabin of the vehicle body unit; when the two vehicle body units are docked to form a combined vehicle 100, the sealing devices 500 of the two vehicle body units dock to form a sealed receiving cavity 520, the receiving cavity 520 being connected to the vacuum pressure pump 510, and the vacuum pressure pump 510 being able to extract the air from the receiving cavity 520, so that the receiving cavity 520 is in a vacuum state.

[0054] In the above embodiment, the vacuum pressure pump 510 starts working to remove the air from the middle position of the two sealing elements. When it is in a near-vacuum state, the vacuum pressure pump 510 stops working.

[0055] Optionally, it also includes:

[0056] The tailgate 600 has a closed position and an open position. When the tailgate 600 is in the closed position, the tailgate 600 closes the rear frame of the vehicle body unit cabin. When the tailgate 600 is in the open position, the tailgate 600 is located at the top of the vehicle body unit.

[0057] The moving mechanism 610 is connected to the vehicle body unit and the tailgate 600 respectively, and is used to drive the tailgate 600 to move to the closed position or the open position.

[0058] In the above embodiments, two opposing flip-up tailgates 600 are provided in the middle of the combined vehicle 100, respectively located in two vehicle body units. After the tailgates 600 are opened, docking locking mechanisms 200 and sealing devices 500 are provided around them. The movable tailgates 600 and the moving mechanism 610 of the present invention are not limited to the mechanism forms described herein, and other retractable, flip-up, and moving motion methods are also possible.

[0059] Optionally, the vehicle body unit is provided with a support wheel drive mechanism 410, which is connected to the support wheel 400. The support wheel drive mechanism 410 can drive the support wheel 400 to move to a retracted position and a supported position. When the support wheel 400 is in the retracted position, the support wheel 400 is away from the ground. When the support wheel 400 is in the supported position, the support wheel 400 is in contact with the ground to support the vehicle body unit.

[0060] Optionally, the docking locking mechanism 200 is an automatic rotation locking mechanism. The corresponding automatic rotation locking mechanisms of the two vehicle body units can rotate to the locking position to complete interlocking. When docking is a combined vehicle, the docking locking mechanisms 200 of the two vehicle body units dock and lock together, combining the two vehicle body units into a combined vehicle 100, ensuring that the sealing elements are tightly pressed together.

[0061] In the above embodiments, preferably, the docking locking mechanism 200 is an automatic rotary locking mechanism. The locking structure is not limited to the mechanism form described herein; snap-fit, press-fit, and fastening are all acceptable.

[0062] Optionally, it also includes a camera 700 and a radar 710, which can be used to detect the relative positions of the two vehicle body units and assist the two vehicle body units in adjusting their attitude to a position where they are directly opposite each other on the rear frame of the cockpit.

[0063] Optionally, it also includes an infrared receiver 900 and an infrared transmitter 910. When the two rear frames of the cockpit are in a facing position, the infrared transmitter 900 emits infrared rays, and the infrared receiver 910 receives the infrared signal to determine the docking status of the two vehicle body units, accurately identify the relative position of the vehicles, and adjust the attitude through the infrared signal to complete the precise docking of the two rear frames of the cockpit.

[0064] In the above embodiments, when the two vehicle body units transform into a combined vehicle, the camera 700 and radar 710 can be used to detect the relative position of the two vehicle body units, helping them adjust their posture. When the two vehicle body units are basically facing each other, the infrared emitters 910 on both sides emit infrared rays, which are received by the infrared receiver 900 to more accurately identify the relative position of the two vehicle body units and make adjustments accordingly. When the infrared receiver 900 detects that the two vehicle body units have been properly fitted, the automatic locking mechanism rotates to the locking position to ensure that the sealing device 500 is tightly pressed together.

[0065] Optionally, it also includes a pressure detection device, which sets a differential pressure threshold. When the differential pressure across the vacuum pressure pump 510 is less than the differential pressure threshold, the vacuum pressure pump 510 starts to work, and when the differential pressure across the vacuum pressure pump 510 is greater than the differential pressure threshold, the vacuum pressure pump 510 stops working.

[0066] In the above embodiments, such as Figure 6 As shown, the two vehicle body units are joined together by mechanical locking and atmospheric pressure. When the pressure detection device detects that the pressure difference across the air pump is less than a set value, the air pump restarts.

[0067] On the other hand, a method for separating a combined vehicle is provided, applied to a combined vehicle as described in any of the above claims, characterized in that it includes:

[0070] If there is an obstacle, an alarm will be sounded, and the position of the combined vehicle will be adjusted to a preset distance where there is no obstacle.

[0071] If there are no obstacles within the preset distance, a signal is sent to control the support wheel drive mechanism to drive the support wheels to contact the ground and support the vehicle body unit.

[0072] A signal is sent to inflate the cavity with air using a vacuum pressure pump, making the pressure difference inside and outside the cavity the same.
