[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0036] The utility model provides a vehicle head structure, which is convenient for maintenance personnel to quickly disassemble the vehicle head structure, thereby improving disassembly and assembly efficiency and simplifying operation steps.

[0037] Please refer to the comprehensive Figures 1 to 3 An embodiment of the present invention provides a vehicle head structure, including a courtyard function actuator 1, a mounting frame 2, a first rotating shaft 3 and a connecting seat 4.

[0038] The yard function actuator 1 is used to perform yard maintenance functions, and may be, but is not limited to, an actuator with functions such as mowing, sweeping snow, and blowing leaves, and may be set according to actual needs.

[0039] The first rotating shaft 3 is rotatably connected to the mounting bracket 2. The connecting base 4 is arranged on the first rotating shaft 3, and the connecting base 4 and the first rotating shaft 3 rotate synchronously.

[0040] In this way, the rotation function of the courtyard function execution mechanism 1 can be realized. The courtyard function execution mechanism 1 can rotate with the first rotation axis 3 as the rotation axis, which makes it easier for the courtyard function execution mechanism 1 to adapt to different terrains and optimize the courtyard function execution effect.

[0041] A first fastener 5 is provided between the courtyard function actuator 1 and the connecting seat 4 for detachable connection. An inspection hole 211 is provided on the mounting frame 2, and the inspection hole 211 is aligned with the first fastener 5. External force can pass through the inspection hole 211 to disassemble the first fastener 5.

[0042] Before the present embodiment is adopted, when maintenance personnel need to repair the courtyard function actuator 1, they need to remove the first rotating shaft 3 and other components from the mounting frame 2, and then separate the courtyard function actuator 1. After the repair is completed, the first rotating shaft 3 and other components must be reinstalled on the mounting frame 2. However, the maintenance personnel do not need to repair the first rotating shaft 3 and other components. Therefore, after adopting this embodiment, a first fastener 5 is set between the courtyard function actuator 1 and the connecting seat 4 for detachable connection, and the first fastener 5 is exposed to the outside by opening a maintenance through hole 211, so that the maintenance personnel can remove the first fastener 5 manually or with a tool through the maintenance through hole 211, thereby separating the courtyard function actuator 1 and the connecting seat 4. The maintenance personnel can directly remove the courtyard function actuator 1 without additionally removing the first rotating shaft 3 from the mounting frame 2. When resetting after the maintenance is completed, the external force can similarly act on the first fastener 5 through the maintenance through hole 211 to lock the courtyard function actuator 1 and the connecting seat 4, which can simplify the disassembly and assembly process. This embodiment has a simple structure and low improvement cost, is convenient for maintenance personnel to disassemble and install, and avoids unnecessary operating procedures.

[0043] Optionally, the mounting bracket 2 may be used to connect to an external structure, such as a vehicle body 10 .

[0044] Optionally, the first fastener 5 may be, but is not limited to, a screw, a positioning pin, a buckle, etc. Optionally, the number of the first fasteners 5 may be set according to actual connection stability requirements.

[0045] Optionally, the first rotating shaft 3 and the connecting seat 4 may be fixedly connected or detachably connected. For example, the first rotating shaft 3 and the connecting seat 4 are welded.

[0046] In some optional embodiments, such as Figure 1 As shown in FIG, the first fastener 5 is a screw with its head facing the inspection through-hole 211. The screw locks the courtyard function actuator 1 to the connecting base 4. When disassembly is required, maintenance personnel can use a tool from the outside through the inspection through-hole 211 to remove the screw and separate the courtyard function actuator 1 and the mounting bracket 2.

[0047] In some optional embodiments, please refer to Figures 3 to 5 The mounting frame 2 includes a rear end wall 21 and two side end walls 22 connected to the left and right sides of the rear end wall 21. An inspection through-hole 211 is opened on the rear end wall 21. The two ends of the first rotating shaft 3 are rotatably connected to the two side end walls 22 respectively. The first rotating shaft 3 can rotate relative to the mounting frame 2, and the connecting seat 4 and the first rotating shaft 3 rotate synchronously, so that the courtyard function actuator 1 can pitch and swing. When the front structure moves on uneven ground, the courtyard function actuator 1 can swing up and down under the action of external force to adapt to different terrains, thereby improving the adaptability of the front structure.

[0048] In some optional embodiments, such as Figure 4 As shown in FIG, shaft sleeves 6 are provided on both side end walls 22, and the two ends of the first rotating shaft 3 are rotatably inserted into the two shaft sleeves 6. The shaft sleeves 6 can play a supporting role, making the rotation of the courtyard function actuator 1 more stable and reliable, protecting the first rotating shaft 3 from unnecessary external damage, and ensuring the correct position of the first rotating shaft 3, so that the courtyard function actuator 1 can obtain more stable rotation performance.

[0049] In some optional embodiments, such as Figure 4 As shown in FIG, both ends of the first rotating shaft 3 are provided with recessed slots, and the two recesses are clamped with retaining springs 7, which are used to press against the shaft sleeve 6 to axially limit the first rotating shaft 3. The shaft sleeve 6 is provided with a second fastener 8, which locks the shaft sleeve 6 to the side end wall 22.

[0050] Furthermore, the diameters of both ends of the first rotating shaft 3 are reduced and respectively inserted into two shaft sleeves 6 .

[0051] In some optional embodiments, such as Figure 4 As shown in FIG, in order to facilitate the installation of the first rotating shaft 3 and the shaft sleeve 6, the side end wall 22 is provided with an assembly hole 221, and the assembly hole 221 extends forward to communicate with the outside.

[0052] In some optional embodiments, such as Figure 2 and Figure 4 As shown in , a detachable cover is provided on the inspection through hole 211. The cover 9 is used to prevent foreign matter from entering the vehicle head structure from the outside.

[0053] In some optional embodiments, such as Figure 5 As shown in , the courtyard function actuator 1 has a second rotating shaft 12 at one end facing the connecting seat 4, and the second rotating shaft 12 extends along the front-to-back direction. A bearing 13 is provided between the second rotating shaft 12 and the connecting seat 4 for rotational connection, and a first fastener 5 fastens the bearing 13 and the connecting seat 4. In this way, the second rotational freedom of the courtyard function actuator 1 can be achieved. The courtyard function actuator 1 can swing left and right with the second rotating shaft 12 as the rotating axis, and the first rotational freedom is pitching and swinging with the first rotating shaft 3. When the front structure moves on uneven ground, the courtyard function actuator 1 can swing left and right and up and down under the action of external force to adapt to different terrains, further improving the adaptability of the front structure.

[0054] The bearing 13 is used to reduce the rotation friction and make the rotation smoother. Figure 5As shown in , the outer ring of the bearing 13 is detachably connected to the connecting seat 4, that is, the first fastener 5 locks the outer ring of the bearing 13 on the connecting seat 4. The inner ring of the bearing 13 is plugged into the second rotating shaft 12, and the outer ring and inner ring of the bearing 13 rotate relative to each other.

[0055] In some optional embodiments, such as Figure 1 and Figure 5 As shown in FIG, the yard function actuator 1 includes a bracket 11, and the end of the second shaft 12 away from the bearing 13 is connected to the bracket 11, and the second shaft 12 rotates synchronously with the bracket 11. The bracket 11 can be used to carry various functional modules, such as a mowing module 14 and the like.

[0056] In some optional embodiments, such as Figure 3 As shown in FIG, a mowing module 14 is provided on the bracket 11. The mowing module 14 includes a first lifting mechanism 141 and a cutter head unit 142. The first lifting mechanism 141 is provided on the bracket 11. The first lifting mechanism 141 is connected to and controls the lifting of the cutter head unit 142.

[0057] The cutter head unit 142 is used to rotate and cut the grass, thereby realizing the mowing function of the vehicle head structure. The first lifting mechanism 141 is used to control the height of the cutter head unit 142, thereby meeting the user's need to cut grass of different heights.

[0058] In some optional embodiments, such as Figure 3 As shown in FIG, the first lifting mechanism 141 includes a first drive device 1411, a guide structure 1412, and a lifting frame 1413. The first drive device 1411 is connected to and controls the lifting of the lifting frame 1413. The cutter head unit 142 is connected to the lifting frame 1413, thereby achieving lifting and lowering control of the cutter head unit 142. The guide structure 1412 is vertically mounted on the bracket 11, and the lifting frame 1413 is slidably connected to the guide structure 1412. Driven by the first drive device 1411, the lifting frame 1413 slides up and down along the guide structure 1412.

[0059] Optionally, the first drive device 1411 may include a first motor and a threaded member. The first motor is connected to and controls the rotation of the threaded member. A nut member is sleeved on the threaded member, the threaded member and the nut member are threadedly connected, and the nut member is fixedly connected to the lifting frame 1413. When the first motor drives the threaded member to rotate, the nut member and the lifting frame 1413 as a whole move up and down along the threaded member. Because the first motor rotates continuously, the position of the nut member and the lifting frame 1413 as a whole within the guide structure 1412 can be continuously and infinitely adjusted, thereby achieving the infinite height adjustment function of the mowing module 14.

[0060] The guide structures 1412 can be columnar, and their number can be adjusted based on actual needs. To improve lifting stability, multiple guide structures 1412 can be distributed circumferentially around the outer perimeter of the threaded member, providing greater balance and stability. During mowing, if the lawn is uneven, the cutterhead unit 142 may accidentally cut into dirt or other debris. Multiple guide structures 1412 can mitigate the impact force on the cutterhead unit 142, improving stability and preventing damage to the mowing module 14.

[0061] In some optional embodiments, the cutter disc unit 142 may include a second drive device and a cutter head. The second drive device is connected to the lifting frame 1413, and the output end of the second drive device is connected to the cutter head. The second drive device controls the rotation of the cutter head, thereby realizing the rotary mowing function of the cutter head.

[0062] In some optional embodiments, such as Figure 3 As shown in FIG, the support 11 is provided with a moving wheel module 15, which includes a second lifting mechanism 151 and a moving wheel 152. The moving wheel 152 is used to roll on the ground. The second lifting mechanism 151 is provided on the support 11, and the second lifting mechanism 151 is connected to and controls the raising and lowering of the moving wheel 152, thereby achieving the height adjustment function of the moving wheel 152.
