[0087] Please refer to Figure 1 . Figure 1 This is a perspective view illustrating an automated moving vehicle 100 according to an embodiment of the present invention. In this embodiment, as... Figure 1 As shown, an automated moving vehicle 100 includes a frame 110, two separate first wheel sets 210, and two separate second wheel sets 220. The frame 110 has a first plate 111 and a second plate 112, which are separate from each other. More specifically, the first plate 111 has two opposing first plate surfaces 111s, and the second plate 112 has two opposing second plate surfaces 112s, with one of the two second plate surfaces 112s corresponding to and separate from one of the two first plate surfaces 111s. The frame 110 is located between the first wheel sets 210 and the second wheel sets 220, and the first wheel sets 210 are secured by a first fastener 120 (see [link to first fastener 120]). Figures 2-5 The first plate 111 is connected to the second wheel assembly 220, which is connected to the second fastener 130 (see the second fastener 130). Figures 7-10 It is connected to the second plate 112.
[0088] Please refer to Figure 2 . Figure 2 For illustration Figure 1 A perspective view of the automated moving vehicle 100, wherein the first wheel assembly 210 is omitted. In this embodiment, as... Figure 2 As shown, the automated mobile vehicle 100 further includes a first fixing member 120 and a first axle 140, the first axle 140 passing through the first fixing member 120 and configured to connect two separate first wheel sets 210 (see [link to first wheel set 210]). Figure 1 ).
[0089] Please refer to Figure 3 . Figure 3 For illustration Figure 2 A perspective view of the first plate 111 and the first fixing member 120, wherein the two are separate from each other. In this embodiment, as... Figure 3 As shown, the first fixing member 120 has two side surfaces 121 and a first mating surface 122 connecting the side surfaces 121. The side surfaces 121 have through holes HP to pass through them. The first shaft 140 (see [reference to first shaft 140])... Figure 2 The first wheel assembly 210 is connected to the first fixed member 120 via the through hole HP. Furthermore, the automatic moving vehicle 100 includes two first protrusions 123, two second protrusions 124, and two third protrusions 125. The two first protrusions 123 are disposed on the first fixed member 120, the two second protrusions 124 are disposed on the first fixed member 120, and the two third protrusions 125 are disposed on the first fixed member 120, wherein the third protrusions 125 are separate from the second protrusions 124 and the first protrusions 123 respectively. Further, the first plate 111 has a plurality of first through holes H1 to penetrate the two first plate surfaces 111s of the first plate 111, and the first protrusions 123, second protrusions 124, and third protrusions 125 are correspondingly inserted into the first through holes H1. More specifically, the shapes of the first protrusion 123, the second protrusion 124 and the third protrusion 125 are substantially matched with their respective corresponding first through holes H1.
[0090] It is worth noting that in this embodiment, the rigidity of the first protrusion 123 is less than the rigidity of the third protrusion 125, or the rigidity of the third protrusion 125 is less than the rigidity of the first protrusion 123, and the rigidity of one of the two second protrusions 124 is less than the rigidity of the other second protrusion 124. Relatively speaking, the third protrusion 125 can be called a rigid member, while the first protrusion 123 can be called an elastic member. The rigid member and the elastic member can be made of the same material or different materials. If the rigid member and the elastic member are made of the same material, their cross-sectional area moment (width and / or thickness) can be selected according to the basic linear deformation formula, and their material can be metal and / or plastic or other suitable materials. In other embodiments, the first fixing member 120 can be called the body, and the first protrusion 123, the second protrusion 124, and the third protrusion 125, along with the body (i.e., the first fixing member 120), can be an integrally formed structure or an assembled structure.
[0091] For example, such as Figure 3 As shown, the first protrusion 123, the second protrusion 124, and the third protrusion 125 are arranged from top to bottom, that is, the elastic member (i.e., the first protrusion 123) is located at the top, and the rigid member (i.e., the third protrusion 125) is located at the bottom. However, depending on the actual situation, the first protrusion 123, the second protrusion 124, and the third protrusion 125 may be arranged from bottom to top, but the present invention is not limited thereto.
[0092] Additionally, for example, located in Figure 3 The rigidity of the second protrusion 124 on the left is less than that of the second protrusion 124 on the right. However, depending on the actual situation, the second protrusions 124 with different rigidities can be interchanged, but the present invention is not limited thereto.
[0093] In practical applications, at least one of the first protrusion 123 and the third protrusion 125 is elongated. However, depending on the actual situation, the first protrusion 123 and the third protrusion 125 may be other shapes, such as, but not limited to, rectangular, cylindrical or elliptical cylindrical shapes.
[0094] Furthermore, such as Figure 3 As shown, the automated moving vehicle 100 further includes a plurality of locking fasteners 170, and the first fixing member 120 further has a plurality of through holes HT corresponding to portions of the first through holes H1, and the locking fasteners 170 pass through the through holes HT and their corresponding first through holes H1. For example, the locking fasteners 170 may be screws or other suitable locking units.
[0095] Please refer to Figure 4 . Figure 4 For illustration Figure 2 A cross-sectional view along line segment AA. In this embodiment, as... Figure 4 As shown, the first mating surface 122 is mated to one of the first plate surfaces 111s of the first plate body 111. This is achieved by a rigid member (e.g., the third protrusion 125, see...). Figure 3 The first through hole H1, which matches the shape of the first plate 111, is inserted into the first plate 111, while the elastic element (e.g., the first protrusion 123, see...) Figure 3 After elastic deformation, it is inserted into other first through holes H1 on the first plate 111 that match the shape, and the first mating surface 122 of the first fixing member 120 is as follows: Figure 4 As shown, the first fastener 120, which is attached to the first plate 111, can be tightly attached to the first plate 111 of the frame 110, so that the first axle 140 passing through the first fastener 120 can have reliable dimensional accuracy relative to the frame 110, which is beneficial for the user to control the first wheel assembly 210 connected to the first axle 140 (see [link]). Figure 1 The position of the vehicle can be adjusted to effectively improve the accuracy of the automatic mobile vehicle 100 during movement.
[0096] Please refer to Figure 5 . Figure 5 For illustration Figure 4 A cross-sectional view along line segment EE. As described above, the shapes of the first protrusion 123, the second protrusion 124, and the third protrusion 125 are substantially matched with their respective corresponding first through holes H1. More specifically, as... Figure 5As shown, the edge of the first protrusion 123 away from the third protrusion 125 is shaped to match the first through hole H1 it passes through, and this edge abuts against the first plate 111. The remaining edges of the first protrusion 123 have gaps with the first plate 111, meaning the remaining edges of the first protrusion 123 do not contact the first plate 111. Similarly, the edge of the third protrusion 125 away from the first protrusion 123 is shaped to match the first through hole H1 it passes through, and this edge abuts against the first plate 111. The remaining edges of the third protrusion 125 have gaps with the first plate 111, meaning the remaining edges of the third protrusion 125 do not contact the first plate 111. Furthermore, the edge of the second protrusion 124 away from the other second protrusion 124 matches the shape of the first through hole H1 it passes through, and this edge abuts against the first plate 111, while the remaining edges of the second protrusion 124 have gaps with the first plate 111, that is, the remaining edges of the second protrusion 124 do not contact the first plate 111.
[0097] Furthermore, such as Figure 5 As shown, the cross-sectional width W1 of the first protrusion 123 extends along the first direction D1, the cross-sectional width W2 of the second protrusion 124 extends along the second direction D2, and the cross-sectional width W3 of the third protrusion 125 is substantially parallel to the first direction D1, and the first direction D1 is different from the second direction D2.
[0098] Please refer to Figure 6 . Figure 6 For illustration Figure 2 A cross-sectional view along line segment BB. In this embodiment, as... Figure 6As shown, the automated mobile carrier 100 further includes a screw 160. The outer surface 140s of the first shaft 140 has a first portion 140a and a second portion 140b. The first portion 140a of the outer surface 140s has a first thread S1, and the second portion 140b of the outer surface 140s has a first groove G1. The inner wall 120w of the through hole HP of the first fixing member 120 has a first portion 120a and a second portion 120b. The first portion 120a of the inner wall 120w has a second thread S2 that corresponds to and engages with the first thread S1, and the second portion 120b of the inner wall 120w has a screw hole HS that corresponds to the first groove G1. The top of the screw 160 passes through the screw hole HS and contacts a portion of the first groove G1. The rotation direction of the screw 160 is different from the rotation direction of the first thread S1. For example, when the first thread S1 of the first shaft 140 couples with the second thread S2 of the first fixing member 120 to fix their relative positions, if the first shaft 140 rotates clockwise relative to the first fixing member 120, the screw 160 rotates counterclockwise relative to the screw hole HS of the first fixing member 120, thereby pressing against the first groove G1 of the first shaft 140. Thus, when the first shaft 140 becomes detached from the first fixing member 120 and rotates counterclockwise relative to the first fixing member 120, the screw 160 will be driven by the first shaft 140 to rotate counterclockwise, causing the screw 160 to further press against the first groove G1 of the first shaft 140, thereby preventing the first shaft 140 from detaching from the first fixing member 120, thus improving the structural stability of the automatic moving vehicle 100.
[0099] Preferably, the first groove G1 surrounds the outer surface 140s of the first shaft 140, and the cross-sectional shape of the first groove G1 may be trapezoidal or V-shaped, while the top of the screw 160 is configured to contact the sidewall of the first groove G1 biased towards the first portion 140a of the first shaft 140.
[0100] Furthermore, such as Figure 6 As shown, a first stepped structure LS1 exists between the first portion 140a and the second portion 140b of the first shaft 140, meaning there is a thickness difference between the two portions. Correspondingly, a second stepped structure LS2 exists between the first portion 120a and the second portion 120b of the inner wall 120w of the through hole HP, meaning there is also a thickness difference between the two portions. In fact, the shapes of the first stepped structure LS1 and the second stepped structure LS2 match each other, and the first stepped structure LS1 and the second stepped structure LS2 correspond and abut.
[0101] Please refer to Figures 7 and 8. Figure 7 For illustration Figure 1A three-dimensional schematic diagram of the automated mobile vehicle 100 from another angle. Figure 8 For illustration Figure 7 A perspective view of the automated moving vehicle 100, wherein the second wheel assembly 220 is omitted. In this embodiment, as... Figure 8 As shown, the automated mobile vehicle 100 further includes a second fixing member 130 and a second axle 150, the second axle 150 passing through the second fixing member 130 and configured to connect two separate second wheel sets 220 (see [link to second wheel set 220]). Figure 7 ).
[0102] Please refer to Figure 9 . Figure 9 For illustration Figure 8 A perspective view of the second plate 112 and the second fixing member 130, wherein the two are separate from each other. In this embodiment, as... Figure 9 As shown, the second fastener 130 has two side surfaces 131 and a second mating surface 132 connecting the side surfaces 131. The side surfaces 131 have through holes HP to pass through them. The second shaft 150 (see [link to second shaft 150])... Figure 8 The second wheel assembly 220 is connected to the second fixed member 130 via the through hole HP. Furthermore, the automated moving vehicle 100 includes two fourth protrusions 133, two fifth protrusions 134, and two sixth protrusions 135. The two fourth protrusions 133, the two fifth protrusions 134, and the two sixth protrusions 135 are disposed on the second fixed member 130, wherein the sixth protrusions 135 are separate from the fifth protrusions 134 and the fourth protrusions 133, respectively. Further, the second plate 112 has a plurality of second through holes H2 to penetrate the two second plate surfaces 112s of the second plate 112, and the fourth protrusions 133, fifth protrusions 134, and sixth protrusions 135 are correspondingly inserted into the second through holes H2. More specifically, the shapes of the fourth protrusion 133, the fifth protrusion 134 and the sixth protrusion 135 are substantially matched with their respective corresponding second through holes H2.
[0103] It is worth noting that in this embodiment, the rigidity of the fourth protrusion 133 is less than that of the sixth protrusion 135, or the rigidity of the sixth protrusion 135 is less than that of the fourth protrusion 133, and the rigidity of one of the two fifth protrusions 134 is less than that of the other fifth protrusion 134. Relatively speaking, the sixth protrusion 135 can be called a rigid member, while the fourth protrusion 133 can be called an elastic member. The rigid member and the elastic member can be made of the same material or different materials. If the rigid member and the elastic member are made of the same material, their cross-sectional area moment (width and / or thickness) can be selected according to the basic linear deformation formula, and their material can be metal and / or plastic or other suitable materials. In other embodiments, the second fixing member 130 can be called the body, and the fourth protrusion 133, the fifth protrusion 134, and the sixth protrusion 135 and the body (i.e., the second fixing member 130) can be an integrally formed structure or an assembled structure.
[0104] For example, such as Figure 9 As shown, the fourth protrusion 133, the fifth protrusion 134, and the sixth protrusion 135 are arranged from top to bottom, that is, the elastic member (i.e., the fourth protrusion 133) is located at the top, and the rigid member (i.e., the sixth protrusion 135) is located at the bottom. However, depending on the actual situation, the fourth protrusion 133, the fifth protrusion 134, and the sixth protrusion 135 may be arranged from bottom to top, but the present invention is not limited thereto.
[0105] Additionally, for example, located in Figure 9 The rigidity of the fifth protrusion 134 on the left side is less than that of the fifth protrusion 134 on the right side. However, depending on the actual situation, the fifth protrusions 134 with different rigidities can be interchanged, but the present invention is not limited thereto.
[0106] In practical applications, at least one of the fourth protrusion 133 and the sixth protrusion 135 is elongated. However, depending on the actual situation, the fourth protrusion 133 and the sixth protrusion 135 may be other shapes, such as, but not limited to, rectangular, cylindrical or elliptical cylindrical shapes.
[0107] Furthermore, such as Figure 9 As shown, the automated moving vehicle 100 further includes a plurality of locking fasteners 170, and the second fastener 130 further has a plurality of through holes HT corresponding to portions of the second through holes H2, and the locking fasteners 170 pass through the through holes HT and their corresponding second through holes H2. For example, the locking fasteners 170 may be screws or other suitable locking units.
[0108] Please refer to Figure 10 . Figure 10 For illustration Figure 8 A cross-sectional view along line segment CC. In this embodiment, as... Figure 10As shown, the second mating surface 132 is mated to one of the second plate surfaces 112s of the second plate body 112. This is achieved by a rigid member (e.g., the sixth protrusion 135, see...). Figure 9 The second through hole H2, which matches the shape of the second plate 112, is inserted into the second plate body 112, while the elastic element (e.g., the fourth protrusion 133, see...) Figure 9 After elastic deformation, it is inserted into other second through holes H2 on the second plate 112 that match the shape, and the second mating surface 132 of the second fastener 130 is as follows: Figure 10 As shown, the second fastener 130, which is attached to the second plate 112, can be tightly attached to the second plate 112 of the frame 110, so that the second axle 150 passing through the second fastener 130 can have reliable dimensional accuracy relative to the frame 110, which is beneficial for the user to control the second wheel assembly 220 connected to the second axle 150 (see...). Figure 1 , 2 The position of 7) can effectively improve the accuracy of the automatic mobile vehicle 100 when it moves.
[0109] Please refer to Figure 11 . Figure 11 For illustration Figure 10 A cross-sectional view along line segment FF. As described above, the shapes of the fourth protrusion 133, the fifth protrusion 134, and the sixth protrusion 135 are substantially matched with their respective corresponding second through holes H2. More specifically, as... Figure 11 As shown, the edge of the fourth protrusion 133 away from the sixth protrusion 135 is shaped to match the second through hole H2 it passes through, and this edge abuts against the second plate 112. The remaining edges of the fourth protrusion 133 have gaps with the second plate 112, meaning the remaining edges of the fourth protrusion 133 do not contact the second plate 112. Similarly, the edge of the sixth protrusion 135 away from the fourth protrusion 133 is shaped to match the second through hole H2 it passes through, and this edge abuts against the second plate 112. The remaining edges of the sixth protrusion 135 have gaps with the second plate 112, meaning the remaining edges of the sixth protrusion 135 do not contact the second plate 112. Furthermore, the edge of the fifth protrusion 134 away from the other fifth protrusion 134 matches the shape of the second through hole H2 it passes through, and this edge abuts against the second plate 112, while the remaining edges of the fifth protrusion 134 have gaps with the second plate 112, that is, the remaining edges of the fifth protrusion 134 do not contact the second plate 112.
[0110] Furthermore, such as Figure 11 As shown, the cross-sectional width W4 of the fourth protrusion 133 extends along the first direction D1, the cross-sectional width W5 of the fifth protrusion 134 extends along the second direction D2, and the cross-sectional width W6 of the sixth protrusion 135 is substantially parallel to the first direction D1.
[0111] Please refer to Figure 12 . Figure 12 For illustration Figure 8 A cross-sectional view along line segment DD. In this embodiment, as... Figure 12 As shown, the automated mobile carrier 100 further includes a screw 160. The outer surface 150s of the second shaft 150 has a first portion 150a and a second portion 150b. The first portion 150a of the outer surface 150s has a first thread S1, and the second portion 150b of the outer surface 150s has a second groove G2. The inner wall 130w of the through hole HP of the second fastener 130 has a first portion 130a and a second portion 130b. The first portion 130a of the inner wall 130w has a second thread S2 that corresponds to and engages with the first thread S1, and the second portion 130b of the inner wall 130w has a screw hole HS that corresponds to the second groove G2. The top of the screw 160 passes through the screw hole HS and contacts a portion of the second groove G2. The rotation direction of the screw 160 is different from the rotation direction of the first thread S1. For example, when the first thread S1 of the second shaft 150 couples with the second thread S2 of the second fixing member 130 to fix their relative positions, if the second shaft 150 rotates clockwise relative to the second fixing member 130, the screw 160 rotates counterclockwise relative to the screw hole HS of the second fixing member 130, thereby pressing against the second groove G2 of the second shaft 150. Thus, when the second shaft 150 becomes detached from the second fixing member 130 and rotates counterclockwise relative to the second fixing member 130, the screw 160 will be driven by the second shaft 150 to rotate counterclockwise, causing the screw 160 to further press against the second groove G2 of the second shaft 150, thereby preventing the second shaft 150 from detaching from the second fixing member 130, thus improving the structural stability of the automatic moving vehicle 100.
[0112] Preferably, the second groove G2 surrounds the outer surface 150s of the second shaft 150, and the cross-sectional shape of the second groove G2 may be trapezoidal or V-shaped, while the top of the screw 160 is configured to contact the sidewall of the second groove G2 biased toward the first portion 150a of the second shaft 150.
[0113] Furthermore, such as Figure 12As shown, a first stepped structure LS1 exists between the first portion 150a and the second portion 150b of the second shaft 150, meaning there is a thickness difference between the two portions. Correspondingly, a second stepped structure LS2 exists between the first portion 130a and the second portion 130b of the inner wall 130w of the through hole HP, meaning there is also a thickness difference between the two portions. In fact, the shapes of the first stepped structure LS1 and the second stepped structure LS2 match each other, and the first stepped structure LS1 and the second stepped structure LS2 correspond and abut.
[0114] In summary, the technical solutions disclosed in the above embodiments of the present invention have at least the following advantages:
[0115] (1) The rigid part of the fastener is inserted into the through hole on the plate body with a matching shape, and the elastic part of the fastener is inserted into other through holes on the plate body with a matching shape after elastic deformation. The mating surface of the fastener is engaged with the plate body. The fastener can be tightly connected to the plate body of the frame, so that the axle passing through the fastener can have reliable dimensional accuracy relative to the frame. This is beneficial for the user to grasp the position of the wheel set connected to the axle, thereby effectively improving the accuracy of the automatic mobile vehicle when it moves.
[0116] (2) Since the rotation direction of the screw is different from the rotation direction of the thread on the shaft, when the shaft comes loose from the fixing part and rotates in a certain direction relative to the fixing part, the screw will be driven by the shaft to rotate in the opposite direction, so that the screw is pressed further into the groove of the shaft, thereby preventing the shaft from coming off the fixing part, thus improving the structural stability of the automatic moving vehicle.
[0117] Although the present invention has been disclosed above by way of embodiments, it is not intended to limit the present invention. Any person skilled in the art can make various modifications and refinements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
