[0040] The following refers to Figures 1 - 4 Describe the landing buffer device 100 and the monolithic flying car 1000 according to the embodiments of the present invention.

[0041] Combined with Figure 1 and Figure 3 For the landing buffer device 100 of the monolithic flying car 1000 according to the present utility model, the monolithic flying car 1000 is provided with an integrated power device 200. The integrated power device 200 can rotate around a first axis to switch between a first position suitable for driving the monolithic flying car 1000 to fly and a second position suitable for driving the monolithic flying car 1000 to travel on the ground.

[0042] It should be noted that the first axis is perpendicular to the central axis of the integrated power device 200.

[0043] Specifically, combined with Figure 1 and Figure 2 When the integrated power device 200 is in the first position, the integrated power device 200 is spaced from the ground and can output flight power. Combined with Figure 3 and Figure 4 When the integrated power device 200 is in the second position, the integrated power device 200 is in contact with the ground and can output ground travel power.

[0044] The integrated power device 200 can rotate around the first axis to adjust the position of the integrated power device 200. By adjusting the position of the integrated power device 200, the working mode of the monolithic flying car 1000 is switched.

[0045] Combined with Figures 1 to 4 The landing buffer device 100 is fixedly connected to the integrated power device 200. The landing buffer device 100 includes: a landing gear 110, and the landing gear 110 is connected to the integrated power device 200; a shock-absorbing wheel 120, and the shock-absorbing wheel 120 is arranged on the landing gear 110. Wherein, the shock-absorbing wheel 120 can roll and support on the ground when the integrated power device 200 is in the first position, and space the integrated power device 200 from the ground. The landing buffer device 100 can be spaced from the ground when the integrated power device 200 is in the second position, and the integrated power device 200 is supported on the ground.

[0046] Specifically, the landing buffer device 100 is installed on the integrated power device 200, and the landing buffer device 100 can rotate synchronously with the integrated power device 200 around the first axis. When the integrated power device 200 is in the first position, the landing gear 110 is located on the side of the integrated power device 200 opposite to the ground, and the shock-absorbing wheel 120 is located at one end of the landing gear 110 opposite to the ground. At this time, the single-body flying vehicle 1000 is in the flight mode. When the single-body flying vehicle 1000 lands on the ground, the shock-absorbing wheel 120 first contacts the ground and rolls to support on the ground. The shock-absorbing wheel 120 can play a shock-absorbing role to reduce the impact on the whole single-body flying vehicle 1000 when the single-body flying vehicle 1000 contacts the ground, so as to protect the single-body flying vehicle 1000.

[0047] Furthermore, the shock-absorbing wheel 120 can keep the integrated power device 200 spaced from the ground to prevent the integrated power device 200 from colliding with the ground when the single-body flying vehicle 1000 lands on the ground, so as to protect the integrated power device 200 and effectively reduce the possibility of damage to the integrated power device 200.

[0048] When the integrated power device 200 is in the second position, the wheel hub 240 of the integrated power device 200 contacts the ground, and the wheel hub 240 can roll on the ground. Among them, the landing buffer device 100 is spaced from the ground to prevent the landing buffer device 100 from interfering with the integrated power device 200 to output the ground walking power, ensure the smoothness of the single-body flying vehicle 1000 when walking on the ground, and prevent damage due to friction between the landing buffer device 100 and the ground.

[0049] According to the landing buffer device 100 of the present invention, the landing buffer device 100 can rotate synchronously with the integrated power device 200 around the first axis to synchronously adjust the position of the landing buffer device 100 when switching the position of the integrated power device 200. When the single-body flying vehicle 1000 is in the flight mode and lands on the ground, the landing buffer device 100 rolls to support on the ground to reduce the impact on the whole single-body flying vehicle 1000 when the single-body flying vehicle 1000 contacts the ground, and keep the integrated power device 200 spaced from the ground to prevent the integrated power device 200 from colliding with the ground. When the single-body flying vehicle 1000 is in the ground walking mode, the landing buffer device 100 is spaced from the ground to ensure the smoothness of the single-body flying vehicle 1000 when walking on the ground, and can prevent the landing buffer device 100 from being damaged due to friction with the ground.

[0050] Combined with Figure 1 and Figure 2, in some embodiments of the present utility model, the landing gear 110 includes: a connecting seat 111 for mounting the integrated power device 200; a bracket main body 112 disposed on the connecting seat 111, and the shock-absorbing wheel 120 is rotatably mounted on the bracket main body 112 about a second axis; wherein, the second axis is parallel to the first axis.

[0051] Specifically, the integrated power device 200 is mounted on the connecting seat 111, and the connecting seat 111 is rotatably connected to the vehicle body 300 about the first axis. The bracket main body 112 is connected to the connecting seat 111 and is used for mounting the shock-absorbing wheel 120. When the single-body flying car 1000 is in the flight mode and lands on the ground, the shock-absorbing wheel 120 is located on the side of the bracket main body 112 close to the ground and rolls to support on the ground. The shock-absorbing wheel 120 can play a shock-absorbing role to reduce the impact on the overall single-body flying car 1000 when it contacts the ground.

[0052] Combined with Figure 2 and Figure 4 , when the single-body flying car 1000 switches from the flight mode to the ground walking mode, the connecting seat 111 rotates about the first axis to drive the integrated power device 200 and the bracket main body 112 to rotate about the first axis. Since the shock-absorbing wheel 120 is rotatably arranged on the bracket main body 112 about the second axis and the second axis is parallel to the first axis, during the rotation of the bracket main body 112 about the first axis, the shock-absorbing wheel 120 can rotate on the ground about the second axis to convert sliding friction into rolling friction, which is beneficial to improving the convenience of position switching of the integrated power device 200 and the landing buffer device 100.

[0053] Combined with Figure 1 and Figure 3 , in some embodiments of the present utility model, there are two bracket main bodies 112, and the two bracket main bodies 112 are respectively arranged on both sides of the connecting seat 111.

[0054] Specifically, the two bracket main bodies 112 are respectively arranged on both sides of the connecting seat 111 in the direction parallel to the first axis, and shock-absorbing wheels 120 are arranged on both of the two bracket main bodies 112. When the single-body flying car 1000 is in the flight mode and lands on the ground, the two bracket main bodies 112 and the shock-absorbing wheels 120 arranged on the two bracket main bodies 112 can respectively support on both sides of the integrated power device 200 in the direction parallel to the first axis, which is beneficial to improving the balance of the integrated power device 200, preventing the integrated power device 200 from tilting, and thus beneficial to improving the balance when the single-body flying car 1000 lands on the ground.

[0055] Combined with Figure 1And Figure 3 In some embodiments of the present utility model, the landing gear 110 further includes a support plate 113. The two ends of the support plate 113 are respectively connected to the two bracket bodies 112 and are used to support and fix the two bracket bodies 112.

[0056] Specifically, the support plate 113 extends along a direction parallel to the first axis, and the two ends of the support plate 113 in the direction parallel to the first axis are respectively connected to the two bracket bodies 112, which is beneficial to improving the connection strength between the two bracket bodies 112, preventing the two bracket bodies 112 from twisting relative to the connection seat 111 due to the large weight when the single - body flying vehicle 1000 lands on the ground, being beneficial to preventing the landing gear 110 from being damaged, and being beneficial to preventing the integrated power device 200 from colliding with the ground due to the twisting or damage of the bracket body 112.

[0057] As Figure 1 shown, in some embodiments of the present utility model, the landing gear 110 further includes a rotating shaft 114. The rotating shaft 114 is respectively connected to the two bracket bodies 112, and the shock - absorbing wheels 120 arranged oppositely in the two bracket bodies 112 are rotatably mounted on the rotating shaft 114.

[0058] Specifically, in the direction parallel to the central axis of the integrated power device 200, the rotating shaft 114 is arranged on the side of the bracket body 112 away from the connection seat 111, and the rotating shaft 114 extends along a direction parallel to the first axis. The rotating shaft 114 is respectively connected to the two bracket bodies 112, which is beneficial to further improving the connection strength between the two bracket bodies 112.

[0059] Further, along the direction parallel to the first axis, the two ends of the rotating shaft 114 respectively extend out of both sides of the two bracket bodies 112, so as to rotatably mount the shock - absorbing wheels 120 on the rotating shaft 114. And the central axis of the rotating shaft 114 is the second axis. During the rotation of the bracket body 112 and the integrated power device 200 around the first axis, the shock - absorbing wheels 120 can rotate on the ground around the second axis to convert sliding friction into rolling friction, which is beneficial to improving the convenience of position switching between the integrated power device 200 and the landing buffer device 100.

[0060] It should be noted that the diameter of the rotating shaft 114 is smaller than the diameter of the shock - absorbing wheel 120 to ensure that the shock - absorbing wheel 120 can rotate on the ground around the central axis of the rotating shaft 114.

[0061] As Figure 1 shown, in some embodiments of the present utility model, the landing gear 110 is provided with a hollow area 115, and at least part of the fan 210 of the integrated power device 200 is arranged opposite to the hollow area 115 in the axial direction of the integrated power device 200.

[0062] Exemplarily, the two bracket bodies 112 are spaced apart in a direction parallel to the first axis, and the two bracket bodies 112 are connected by a connecting shaft so that the landing gear 110 is formed with a hollow area 115, which is beneficial to reducing the production cost and weight of the landing gear 110.

[0063] In the axial direction of the integrated power device 200, the orthographic projection of the hollow area 115 and the orthographic projection of the fan 210 have an overlapping area. For example, the orthographic projection of the fan 210 may coincide with the orthographic projection of the hollow area 115, or the orthographic projection of part of the fan 210 near the rotation center of the fan 210 may coincide with the orthographic projection of the hollow area 115. By arranging the hollow area 115 relative to at least part of the fan 210, the hollow area 115 can avoid the airflow formed by the fan 210, which is beneficial to prevent the integrated power device 200 from outputting flight power due to the wind blocking of the landing gear 110.

[0064] Combination Figures 1 - 4 In some embodiments of the utility model, the bracket body 112 includes: a first support rod 1121, one end of the first support rod 1121 is connected to the connecting seat 111 and extends along the axial direction of the integrated power device 200; a second support rod 1122, one end of the second support rod 1122 is connected to the connecting seat 111 and extends along the radial direction of the integrated power device 200; a third support rod 1123, both ends of the third support rod 1123 are respectively connected to the other end of the first support rod 1121 and the other end of the second support rod 1122, and a part of the third support rod 1123 is suitable for sliding with the ground when the integrated power device 200 switches positions.

[0065] Specifically, the first support rod 1121 extends from the connecting seat 111 along the axial direction parallel to the integrated power device 200 to the end away from the fan 210, and the end of the first support rod 1121 away from the connecting seat 111 protrudes from the end of the integrated power device 200 away from the fan 210, that is, the end of the first support rod 1121 away from the connecting seat 111 is spaced apart from the end of the integrated power device 200 away from the fan 210, and the shock-absorbing wheel 120 is located at the end of the first support rod 1121 away from the connecting seat 111, so that when the single-body flying car 1000 lands on the ground, the shock-absorbing wheel 120 and the first support rod 1121 are supported between the ground and the integrated power device 200 to prevent the integrated power device 200 from colliding with the ground.

[0066] Further, the second support rod 1122 is connected to the connection seat 111 and extends in a direction away from the vehicle body 300 perpendicular to the first support rod 1121, and one end of the second support rod 1122 away from the first support rod 1121 is spaced from the outer peripheral wall of the wheel hub 240 of the integrated power device 200. Combining Figure 3 and Figure 4 , when the single-unit flying car 1000 is in the ground walking mode, the integrated power device 200 rotates to the second position. At this time, the shock-absorbing wheel 120 is separated from the ground, and the first support rod 1121 can be parallel to the ground, the wheel hub 240 is in contact with the ground, and one end of the second support rod 1122 away from the connection seat 111 is spaced from the ground to prevent interference with the rolling of the wheel hub 240 on the ground due to the contact of the second support rod 1122 with the ground.

[0067] Further, the third support rod 1123 is connected between the first support rod 1121 and the second support rod 1122, which is beneficial to improving the structural strength of the landing gear 110. And when the integrated power device 200 switches between the first position and the second position, the third support rod 1123 can slide on the ground to play a role of transition and guiding, effectively improving the convenience of the position switching of the integrated power device 200.

[0068] Combining Figures 1 - 4 , in some embodiments of the present invention, the third support rod 1123 includes: a straight rod section 11231, one end of the straight rod section 11231 is connected to the first support rod 1121, the straight rod section 11231 is arranged parallel to the second support rod 1122, and the shock-absorbing wheel 120 is arranged on the straight rod section 11231; an arc rod section 11232, the arc rod section 11232 is connected between the other end of the straight rod section 11231 and the second support rod 1122, and the arc opening of the arc rod section 11232 faces away from the ground side and is used for sliding cooperation with the ground.

[0069] Specifically, the straight rod section 11231 is arranged parallel to the second support rod 1122, and in the axial direction of the integrated power device 200, the straight rod section 11231 is opposite and spaced from the second support rod 1122. When the single-unit flying car 1000 lands on the ground, the straight rod section 11231 is closer to the ground than the arc rod end. By arranging the shock-absorbing wheel 120 on the straight rod section 11231, it is beneficial to ensure that the shock-absorbing wheel 120 can contact the ground first when the single-unit flying car 1000 lands on the ground, ensuring that the shock-absorbing wheel 120 can play a shock-absorbing effect.

[0070] Further, one end of the arc-shaped rod segment 11232 is connected to the end of the straight rod segment 11231 away from the first support rod 1121, and the other end of the arc-shaped rod segment 11232 is connected to the end of the second support rod 1122 away from the connecting seat 111. The arc-shaped rod segment 11232 is formed with an arc-shaped opening, and the arc-shaped opening is arranged facing the first support rod 1121 and the second support rod 1122. During the process of the integrated power device 200 switching between the first position and the second position, the arc-shaped rod segment 11232 can rotate and slide on the ground to improve the transition and guiding effect of the third support rod 1123, effectively improving the convenience of the position switching of the integrated power device 200.

[0071] Combined Figure 1 with Figure 2 , in some embodiments of the present utility model, the straight rod segment 11231 is provided with a plurality of shock-absorbing wheels 120, and the plurality of shock-absorbing wheels 120 are arranged at intervals in sequence along the extending direction of the straight rod segment 11231.

[0072] Specifically, a plurality of rotating shafts 114 are arranged between the straight rod segments 11231 of the two bracket bodies 112, and the plurality of rotating shafts 114 are arranged parallel and at intervals along the extending direction of the straight rod segment 11231. Shock-absorbing wheels 120 are arranged at both axial ends of each rotating shaft 114. By arranging a plurality of shock-absorbing wheels 120 on the straight rod segment 11231, the contact points between the single-body flying vehicle 1000 and the ground when landing are increased, which is beneficial to improving the stability of the single-body flying vehicle 1000 when landing on the ground.

[0073] Among them, the rotating shaft 114 can be set to two, and shock-absorbing wheels 120 are arranged at both axial ends of each rotating shaft 114, that is, four shock-absorbing wheels 120 are arranged on the landing buffer device 100, which can ensure the buffer and shock-absorbing effect of the landing buffer device 100 while being beneficial to simplifying the component setting of the landing buffer device 100 and reducing the production cost of the landing buffer device 100.

[0074] In some embodiments of the present utility model, the shock-absorbing wheel 120 is configured as a rubber wheel to improve the buffer and shock-absorbing effect of the shock-absorbing wheel 120, effectively reducing the vibration and noise when the single-body flying vehicle 1000 lands and walks on the ground, and the rubber wheel has good wear resistance, which is beneficial to improving the service life of the shock-absorbing wheel 120.

[0075] The single-body flying vehicle 1000 according to the present utility model includes the above-mentioned landing buffer device 100.

[0076] Since the single - body flying vehicle 1000 is provided with the above - mentioned landing buffer device 100, the landing buffer device 100 can rotate synchronously with the integrated power device 200 around the first axis to synchronously adjust the position of the landing buffer device 100 when switching the position of the integrated power device 200. When the single - body flying vehicle 1000 is in the flight mode and lands on the ground, the landing buffer device 100 rolls and supports on the ground to reduce the impact on the whole single - body flying vehicle 1000 when it contacts the ground, and makes the integrated power device 200 spaced from the ground to avoid the integrated power device 200 colliding with the ground. When the single - body flying vehicle 1000 is in the ground walking mode, the landing buffer device 100 is spaced from the ground to ensure the smoothness of the single - body flying vehicle 1000 when walking on the ground and prevent the landing buffer device 100 from being damaged due to friction with the ground.

[0077] Referring to Figure 1 , in some embodiments of the present utility model, the single - body flying vehicle 1000 includes an integrated power device 200. The integrated power device 200 includes a fan 210, a driving motor 220, a duct wall 230, and a wheel hub 240. A connecting seat 111 is sleeved on the radial outer side of the driving motor 220 and is connected to the driving motor 220. A shock - absorbing wheel 120 is spaced from one end of the driving motor 220 away from the fan 210 in the axial direction, so that when the single - body flying vehicle 1000 lands on the ground, the landing buffer device 100 can support on the ground and keep the driving motor 220 spaced from the ground, preventing the driving motor 220 from colliding with the ground.

[0078] Further, the fan 210 is arranged on the duct wall 230, the wheel hub 240 is sleeved on the radial outer side of the duct wall 230, the driving motor 220 is respectively power - connected to the fan 210 and the wheel hub 240. The driving motor 220 can drive the fan 210 to rotate, and the driving motor 220 can drive the wheel hub 240 to rotate relative to the duct wall 230.

[0079] Among them, in combination with Figure 1 and Figure 2 , when the integrated power device 200 is in the first position, the central axis of the integrated power device 200 (which can also be understood as the central axis of the driving motor 220) is perpendicular to the ground, and the fan 210 is located on the side of the integrated power device 200 away from the ground in the axial direction. The driving motor 220 drives the fan 210 to rotate and generates an air flow to form a thrust, so as to realize that the integrated power device 200 provides flight power for the single - body flying vehicle 1000 and realize the flight mode of the single - body flying vehicle 1000.

[0080] Combined with Figure 3 and Figure 4, when the integrated power device 200 is in the second position, the central axis of the integrated power device 200 is parallel to the ground, and the wheel hub 240 contacts the ground. The drive motor 220 can drive the wheel hub 240 to rotate relative to the duct wall 230, so that the wheel hub 240 can roll on the ground, realizing that the integrated power device 200 provides ground walking power for the single-body flying car 1000 and realizing the ground walking mode of the flying car.

[0081] The integrated power device 200 can rotate around the first axis to switch the integrated power device 200 between the first position and the second position, thereby switching the working mode of the single-body flying car 1000. Thus, by driving the drive motor 220 to drive the wheel hub 240 and the fan 210 to rotate, the integrated power device 200 can output flight power and ground walking power without setting an additional motor to drive the wheel hub 240 to rotate, effectively simplifying the structure of the integrated power device 200, realizing weight reduction and cost reduction of the integrated power device 200, and thus being beneficial to realizing weight reduction and cost reduction of the single-body flying car 1000.

[0083] Specifically, the vehicle body 300 serves as an installation carrier for installing the attitude adjustment device 400 and the integrated power device 200. The conversion servo 410 is installed on the vehicle body 300, and the conversion servo 410 is power-connected to the landing gear rotating shaft complex 420. When the conversion servo 410 works, the conversion servo 410 can drive the landing gear rotating shaft complex 420 to rotate around the first axis, and the landing gear rotating shaft complex 420 drives the integrated power device 200 to rotate around the first axis to switch the position of the integrated power device 200.

[0085] Specifically, the connecting shaft assembly 520 is arranged on the connecting seat 111, and the connecting shaft assembly 520 extends away from the connecting seat 111 along a direction parallel to the radial direction of the integrated power device 200. The central axis of the connecting shaft assembly 520 is the third axis, and the third axis is perpendicular to the first axis, the second axis, and the central axis of the integrated power device 200.

[0086] Furthermore, the connecting shaft assembly 520 connects the integrated power device 200 to the output shaft of the steering servo 510, and the third axis is collinear with the central axis of the output shaft of the steering servo 510. When the monolithic flying car 1000 is in the ground walking mode, the output shaft of the steering servo 510 can drive the connecting shaft assembly 520 to rotate, and the connecting shaft assembly 520 drives the integrated power device 200 to rotate around the third axis, thereby adjusting the rotation angle of the integrated power device 200 on the ground and realizing the adjustment of the steering angle of the monolithic flying car 1000 in the ground walking mode.

[0087] Combined Figure 1 and Figure 3 , in some embodiments of the present utility model, a main take-off and landing shaft rotating shaft 310 is arranged on the vehicle body 300, and the central axis of the main take-off and landing shaft rotating shaft 310 is the first axis. The take-off and landing frame rotating shaft complex 420 includes: a connecting main body 421, which is connected to the output end of the conversion servo 410; a connecting arm 422, which is connected to the end of the connecting main body 421 away from the conversion servo 410, and the connecting arm 422 extends along a direction parallel to the first axis; a steering shaft 423, which is arranged at the end of the connecting arm 422 and sleeved on the connecting shaft assembly 520, and the steering shaft 423 is rotatably connected to the main take-off and landing shaft rotating shaft 310 and is adapted to rotate around the first axis relative to the main take-off and landing shaft rotating shaft 310.

[0088] Specifically, the rotation center line of the output end of the conversion servo 410 is parallel and collinear with the first axis. The conversion servo 410 can drive the connection body 421 to rotate around the first axis. The connection body 421 is connected to the connection arm 422, and a steering shaft 423 is arranged at the axial end of the connection arm 422. The steering shaft 423 is rotatably mounted on the vehicle body 300 through the main rotation shaft 310 of the take-off and landing shaft. When the conversion servo 410 drives the connection body 421 to rotate around the first axis, the connection body 421 drives the steering shaft 423 to rotate around the first axis relative to the main rotation shaft 310 of the take-off and landing shaft through the connection arm 422.

[0089] Further, one end of the steering shaft 423 away from the main rotation shaft 310 of the take-off and landing shaft is sleeved and fitted with the connection shaft assembly 520. When the conversion servo 410 drives the steering shaft 423 to rotate around the first axis through the connection body 421 and the connection arm 422, the steering shaft 423 can drive the connection shaft assembly 520 to rotate around the first axis, and the connection shaft assembly 520 can drive the integrated power device 200 to rotate around the first axis to switch the position of the integrated power device 200.

[0090] Wherein, by arranging the steering shaft 423, the connection shaft assembly 520 is arranged in a dislocation manner with respect to the main rotation shaft 310 of the take-off and landing shaft, which facilitates the independent rotation of the connection shaft assembly 520 around the main rotation shaft 310 of the take-off and landing shaft to avoid the interference between the rotation of the connection shaft assembly 520 around the third axis and the rotation of the connection shaft assembly 520 around the first axis.

[0091] Combined with Figure 1 and Figure 3 , in some embodiments of the present invention, a guide seat 320 is arranged on the vehicle body 300, and the guide seat 320 is in guiding cooperation with the steering servo 510.

[0092] Specifically, when the attitude adjustment device 400 drives the integrated power device 200 to rotate around the first axis, since the steering servo 510 is connected to the integrated power device 200 through the connection shaft assembly 520, when the integrated power device 200 rotates around the first axis, it can drive the steering servo 510 to rotate around the first axis synchronously through the connection shaft assembly 520. By arranging the guide seat 320 to guide the rotation direction of the steering servo 510, the stability of the rotation direction of the steering servo 510 when rotating around the first axis is ensured, and the deviation of the steering servo 510 is prevented.

[0093] Wherein, the guide seat 320 can be formed with a guide groove 321, and the groove wall of the guide groove 321 can be in limit cooperation with the steering servo 510 to prevent the steering servo 510 from rotating around the third axis, and at the same time, it can prevent the steering servo 510 from rotating excessively when rotating around the first axis, thereby preventing the integrated power device 200 from rotating excessively around the first axis and deviating.
