[0077] During the construction of a rooftop photovoltaic power station, the photovoltaic modules must first be transported to the roof of the building and then transported to the desired location. Conventional methods mainly rely on manual transportation or manual carts to transport the modules to the desired location.

[0078] When relying on manual transportation, the labor intensity is high, the transportation efficiency is low, and the labor cost is high because the photovoltaic modules are heavy, large in number, and have to be transported over long distances.

[0079] When relying on carts for transportation, the transportation efficiency is still low and the labor cost is high due to the rugged transportation surface on the roof; the slope of the guide rails on the roof causes the risk of photovoltaic panels falling.

[0080] Since the transportation surface of the roof is rugged, such as the color steel tile roof, both of the above two transportation methods have the safety risk of operators falling and getting injured.

[0081] Based on the above problems, an embodiment of the present application provides a photovoltaic module transportation device that can transport photovoltaic modules on a rooftop to reduce labor costs, improve transportation efficiency, and reduce safety risks.

[0082] The photovoltaic module transportation device is described in detail below through two embodiments.

[0083] Example 1

[0084] like Figure 1 and Figure 10 As shown, the photovoltaic module transportation device provided in the first embodiment of the present application includes: a chassis assembly 1, a driving mechanism 2 and a wheel assembly 3.

[0085] The chassis assembly 1 is used to place the photovoltaic assembly 03 .

[0086] The wheel assembly 3 is used to contact the guide rail 02 on the roof 01. The guide rail 02 can be understood as a connector for securing the photovoltaic module to the roof 01. This fully utilizes the connector (guide rail 02) on the roof 01, eliminating the need for a separate guide rail structure on the roof 01 and simplifying the roof structure.

[0087] The above-mentioned roof can be a color steel tile roof or a roof of other structures. The color steel tile roof can be an industrial or commercial color steel tile roof, which is not limited in the embodiments of the present application.

[0088] The drive mechanism 2 is disposed on the chassis assembly 1. For example, the drive mechanism 2 is located on the bottom side of the chassis assembly 1. The drive mechanism 2 drives the wheel assembly 3 to rotate and move along the guide rail 02, thereby moving the chassis assembly 1. This enables the photovoltaic module transport device to automatically move on the roof 01, effectively transporting the photovoltaic modules 03 on the roof 01. Compared to conventional technologies, this eliminates the need for manual transport of the photovoltaic modules 03, freeing up labor, effectively reducing labor costs, and improving transportation efficiency. It also reduces the risk of operator falls and injuries, thereby minimizing safety risks.

[0089] In the photovoltaic module transport device, the wheel assembly 3 and the drive mechanism 2 can be detachably mounted on the chassis assembly 1, for example, by means of threaded fasteners such as screws, thereby facilitating installation, disassembly, and maintenance.

[0090] The above-mentioned photovoltaic module transportation device realizes the automatic transportation of photovoltaic modules 03, providing a prerequisite for the subsequent fully automated installation of photovoltaic modules 03.

[0091] In the embodiment of the present application, the wheel assembly 3 includes a connecting shaft 31 and a wheel 32 , wherein the connecting shaft 31 is arranged on the chassis assembly 1 , the wheel 32 is used to contact the guide rail 02 , and the wheel 32 is arranged on the connecting shaft 31 .

[0092] To facilitate the movement of chassis assembly 1, wheel assembly 3 may include a driving wheel assembly 3a and a driven wheel assembly 3b. In the direction of movement of chassis assembly 1, driving wheel assembly 3a and driven wheel assembly 3b are located at opposite ends of chassis assembly 1. Each of driving wheel assembly 3a and driven wheel assembly 3b includes a connecting shaft 31 and a wheel 32. Drive mechanism 2 rotates wheel 32 of driving wheel assembly 3a, while wheel 32 of driven wheel assembly 3b supports chassis assembly 1 and rotates with wheel 32 of driving wheel assembly 3a.

[0093] In the above case, at least one wheel 32 is a driving wheel 32a, and at least one wheel 32 is a driven wheel 32b. The connecting shaft 31 corresponding to the driving wheel 32a can be called a driving shaft 31a, and the connecting shaft 31 corresponding to the driven wheel 32b can be called a driven shaft 31b.

[0094] In actual situations, it is also possible to choose to set the driven wheel assembly 3b or the driving wheel assembly 3a in the middle of the chassis assembly 1; or, the wheel assembly includes the driving wheel assembly 3a but does not include the driven wheel assembly 3b, and the driving wheel assembly 3a is distributed at both ends of the chassis assembly 1. In this case, all wheels 32 are active wheels 32a.

[0095] like Figure 4 and Figure 5As shown, there are two driving wheels 32a, which are arranged on the same driving shaft 31a, and the two driving wheels 32a are symmetrically distributed on the driving shaft 31a. Figure 1 and Figure 7 As shown, there are two driven wheels 32b, so that the number of driven wheels 32b is the same as the number of driving wheels 32a; the two driven wheels 32b are set on different driven shafts 31b, and the two driven wheels 32b are symmetrically distributed on both sides of the chassis assembly 1.

[0096] In actual situations, the number of driving wheels 32a and driven wheels 32b can also be selected to be other numbers, such as more than three; the number of driven wheels 32b and driving wheels 32a can be the same or different; all driven wheels 32b can also be set on the same driven shaft 31b; at least two driving wheels 32a are set on different driving shafts 31a.

[0097] In order to improve the stability of the photovoltaic module transportation device, at least two wheels 32 may be selected in the axial direction of the wheels 32 .

[0098] It should be noted that the axial direction of the wheel 32 is the same as the axial direction of the connecting shaft 31 , and the axial direction is perpendicular to the moving direction of the chassis assembly 1 .

[0099] The driving mechanism 2 drives the active wheel 32a to rotate and move along the guide rail 02, so that the chassis assembly 1 moves.

[0100] The drive mechanism 2 can drive all active wheels 32a to rotate synchronously. This improves the stability of the photovoltaic module transport device and simplifies the control system of the photovoltaic module transport device. In this case, all active wheels 32a can be installed on the same drive shaft 31a. The drive assembly 21 drives the drive shaft 31a through the transmission mechanism 22 to rotate, thereby achieving synchronous rotation of all active wheels 32a. This also effectively improves the synchronization of all active wheels 32a and further simplifies the control system of the photovoltaic module transport device.

[0101] The specific type of the driving mechanism 2 is selected according to the actual situation. In some embodiments, Figure 1 、 Figure 4 、 Figure 5 and Figure 8 As shown, the drive mechanism 2 includes a drive component 21, a transmission mechanism 22 and a bracket component 23, wherein the bracket component 23 includes a drive bracket component 23a and a driven bracket component 23b, the drive component 21, the transmission mechanism 22 and the driving shaft 31a are all arranged on the drive bracket component 23a, the driven shaft 31b is arranged on the driven bracket component 23b, and the drive bracket component 23a and the driven bracket component 23b are both fixedly connected to the chassis component 1.

[0102] The driving assembly 21 may include a driving component 211 and a reduction mechanism 212 , and the driving component 211 is connected to the transmission mechanism 22 via the reduction mechanism 212 .

[0103] The driving component 211 may be a motor or other component; the reduction mechanism 212 may be a gear reduction mechanism. The specific type of the gear reduction mechanism is selected according to actual conditions and is not limited in this embodiment of the present application.

[0104] The transmission mechanism 22 can be a belt transmission mechanism, a chain transmission mechanism, a gear transmission mechanism, etc., which is not limited in the first embodiment of the present application.

[0105] like Figure 4 and Figure 5 As shown, the drive bracket assembly 23a includes a first drive bracket 231 and a second drive bracket 232; the drive assembly 21 and the transmission mechanism 22 are both arranged on the first drive bracket 231, the driving shaft 31a is arranged on the first drive bracket 231 and the second drive bracket 232, and the first drive bracket 231 and the second drive bracket 232 are both fixed to the chassis assembly 1.

[0106] To conserve space, the drive mechanism 2 can be positioned between the two ends of the driving shaft 31a. Accordingly, the first drive bracket 231 is positioned between the two ends of the driving shaft 31a. To ensure the stability of the driving shaft 31a, at least two second drive brackets 232 are provided, arranged axially along the driving shaft 31a. Two second drive brackets 232 are positioned at each end of the driving shaft 31a, while the remaining second drive brackets 232 are positioned between the two ends of the driving shaft 31a.

[0107] Exemplarily, there are three second drive brackets 232: one intermediate bracket 232a and two side brackets 232b. The first drive bracket 231 is located between the intermediate bracket 232a and one side bracket 232b. One driving wheel 32a is located between the intermediate bracket 232a and one side bracket 232b, and another driving wheel 32a is located between the first drive bracket 231 and another side bracket 232b.

[0108] In order to ensure the stability of the driving shaft 31a, the end of the driving shaft 31a and the second driving bracket 232 are relatively fixed in the axial direction. Figure 4-Figure 6The second drive bracket 232 shown at the end of the active shaft 31a is provided with a stepped hole 2321, and the stepped hole 2321 includes a large hole 23211 and a small hole 23212 that are connected. The large hole 23211 and the smaller hole 23212 are close to the first drive bracket 231, and the second bearing 35 is located in the large hole 23211, and the end wall of the large hole 23211 and the second bearing 36 are matched in the axial upper limit position; the end of the active shaft 31a is a stepped shaft structure 311, and the second bearing 36 is located in the thin shaft section of the stepped shaft structure 311, and the end face of the thick shaft section of the stepped shaft structure 311 and the second bearing 36 are matched in the axial upper limit position.

[0109] like Figure 1 and Figure 8 As shown, the driven bracket assembly 23b includes at least two driven brackets 233, and the driven shaft 31b is arranged on the driven bracket 233. When the driven shaft 31b is in transmission connection with the driven wheel 32b, the driven shaft 31b can be rotatably arranged on the driven bracket 233 through the third bearing 37.

[0110] To ensure the stability of the driven shaft 31b, at least both ends of the driven shaft 31b are rotatably mounted on the driven bracket 233. The ends of the driven shaft 31b and the driven bracket 233 are axially fixed relative to each other. For details on how this relative fixation is achieved, refer to the axially fixed structure of the driving shaft 31a and the second driving bracket 232, and will not be further described here.

[0111] The number of driven brackets 233 is selected according to actual conditions and is not limited in this embodiment of the present application.

[0112] To facilitate installation, disassembly and maintenance, the above-mentioned brackets (first drive bracket 231, second drive bracket 232, driven bracket 233) can be selected to be detachably fixed to the chassis assembly 1. For example, each bracket is detachably fixed to the chassis assembly 1 by screws or other components.

[0113] The shape and size of each of the above-mentioned brackets are selected according to actual conditions and are not limited in this embodiment of the present application.

[0114] The material of the bracket assembly 23 is selected based on actual conditions. To reduce the weight of the bracket assembly 23 and improve transportation convenience, the bracket assembly 23 can be selected to be a lightweight component. It should be noted that the material of the lightweight component is a lightweight material, which mainly includes titanium alloy, magnesium alloy, and aluminum alloy. Each of the above brackets can be an aluminum alloy profile or an aluminum alloy square tube, which is not limited in this embodiment of the present application.

[0115] There are multiple guide rails 02 on the roof 01, and the direction in which the multiple guide rails 02 are sequentially distributed is parallel to the axial direction of the wheels 32. In this way, the distance between two adjacent wheels 32 in the axial direction of the wheels 32 must be adapted to the distance between two adjacent guide rails 02 to ensure that the photovoltaic module transport device can move normally along the guide rails 02.

[0116] In practice, the spacing between two adjacent guide rails 02 can be the same or different. For example, the spacing between two adjacent guide rails 02 on a color-coated steel tile roof can be different. To ensure that the photovoltaic module transport device can adapt to roofs 01 with different guide rail spacings, the position of the wheels 32 on the chassis assembly 1 is adjustable along the axial direction of the wheels 32.

[0117] In an embodiment of the present application, the wheel 32 is detachably fixedly connected to the chassis assembly 1 via the connecting shaft 31. When the fixed connection between the wheel 32 and the chassis assembly 1 is removed, the wheel 32 and the chassis assembly 1 can slide relative to each other along the axial direction of the wheel 32, and the wheel 32 can be detachably fixedly connected to the chassis assembly 1 via the connecting shaft 31 at multiple positions during the sliding process.

[0118] When the guide rail spacing between two adjacent guide rails 02 changes, the fixed connection between the wheel 32 and the chassis assembly 1 is released, and the wheel 32 is slid along the axial direction of the wheel 32 so that the spacing between the two adjacent wheels 32 in the axial direction is adapted to the guide rail spacing. Then, the wheel 32 is fixedly connected to the chassis assembly 1 through the connecting shaft 31, and the driving mechanism 2 can drive the active wheel 32 to rotate.

[0119] Based on the above content, the photovoltaic module transport device provided in Example 1 of the present application realizes the adjustable spacing between two adjacent wheels 32 in the axial direction of the wheel 32, so that the photovoltaic module transport device can adapt to the roof 01 with a guide rail spacing within a set range, thereby improving the adaptability of the photovoltaic module transport device to the roof 01 (such as a color steel tile roof) and expanding the scope of use of the photovoltaic module transport device.

[0120] It should be noted that, in the adjustment state, the distance that the wheel 32 and the chassis assembly 1 can slide relative to each other in the axial direction is selected according to actual conditions, and this is not limited in the first embodiment of the present application.

[0121] In the first embodiment of the present application, in order to achieve that the position of the wheel 32 on the chassis assembly 1 can be adjusted along the axial direction of the wheel 32 , the position of the wheel 32 on the connecting shaft 31 can be adjusted along the axial direction of the wheel 32 .

[0122] In some embodiments, as Figure 4 and Figure 8 As shown, the driving wheel 32a and the driven wheel 32b are both regulating wheels 32c, which can be understood as: all wheels 32 are regulating wheels 32c.

[0123] In actual situations, at least one driven wheel 32b can be selected as the regulating wheel 32c, or at least one driving wheel 32a can be selected as the regulating wheel 32c. Figure 4 and Figure 8 The scheme shown.

[0124] The adjusting wheel 32c and the connecting shaft 31 are detachably fixedly connected, and the adjusting wheel 32c and its corresponding connecting shaft 31 are connected by a transmission key, which is a flat key or a spline.

[0125] like Figure 5 As shown, the connecting shaft 31 corresponding to the driving wheel 32a can be called the driving shaft 31a; Figure 5 and Figure 6 As shown, the driving wheel 32a and the driving shaft 31a can be connected by a second transmission key 38. The driving mechanism 2 drives the driving wheel 32a to rotate through the driving shaft 31a. The driving shaft 31a plays a supporting role and a torque transmission role for the driving wheel 32a. In this structure, the second transmission key 38 is fixed on the driving shaft 31a. The second transmission key 38 is a flat key; Figure 9 As shown, the wheel 32 (driving wheel 32a) is provided with a wheel keyway 3221 that cooperates with a flat key.

[0126] like Figure 8 As shown, the connecting shaft 31 corresponding to the driven wheel 32b can be called the driven shaft 31b. The driven wheel 32b and the driven shaft 31b can be connected by a first transmission key 33. In this structure, the first transmission key 33 is fixed on the driven shaft 31b, and the first transmission key 33 is a flat key; Figure 9 As shown, the wheel 32 (driven wheel 32b) is provided with a wheel keyway 3221 that cooperates with a flat key.

[0127] like Figure 7 As shown, the first transmission key 33 can also be a spline. Accordingly, the wheel 32 is provided with a wheel keyway that cooperates with the spline.

[0128] The transmission key (the first transmission key 33 and the second transmission key 38) is fixedly connected to the connecting shaft 31. The transmission key and the connecting shaft 31 can be detachably fixedly connected, for example, by a fastener. Of course, the transmission key and the connecting shaft 31 can be fixedly connected to each other in an inseparable manner, for example, by bonding the transmission key and the connecting shaft 31. This is not limited in the present embodiment.

[0129] like Figure 9As shown, the adjustable wheel 32c can be selected to include a wheel body 321 and a clamping sleeve 322. The wheel body 321 is used to contact the guide rail 02 and is externally mounted on the connecting shaft 31, with the wheel body 321 and the connecting shaft 31 slidingly engaging in the axial direction; the clamping sleeve 322 is externally mounted on the connecting shaft 31 and is located at one or both ends of the wheel body 321 in the axial direction.

[0130] The clamping sleeve 322 can clamp and release the connecting shaft 31. When the clamping sleeve 322 releases the connecting shaft 31, the clamping sleeve 322 and the connecting shaft 31 slide together in the axial direction, and the clamping sleeve 322 can clamp the connecting shaft 31 at any position during the sliding process. When the clamping sleeve 322 clamps the connecting shaft 31, the clamping sleeve 322 and the wheel body 321 are relatively fixed in the axial direction.

[0131] For example, on one hand, the clamping sleeve 322 is located at one axial end of the wheel body 321. When the clamping sleeve 322 clamps the connecting shaft 31, the clamping sleeve 322 and the wheel body 321 are fixedly connected, so that the clamping sleeve 322 and the wheel body 321 are relatively fixed in the axial direction. On the other hand, the clamping sleeve 322 is located at both axial ends of the wheel body 321. When the clamping sleeve 322 clamps the connecting shaft 31, the clamping sleeve 322 and the wheel body 321 are fixedly connected, so that the clamping sleeve 322 and the wheel body 321 are relatively fixed in the axial direction. Alternatively, when the clamping sleeve 322 clamps the connecting shaft 31, the clamping sleeves 322 located at both ends of the wheel body 321 are positioned at the upper limit of the axial position, so that the clamping sleeve 322 and the wheel body 321 are relatively fixed in the axial direction.

[0132] In the above structure, the position of the wheel 32c on the connecting shaft 31 can be adjusted by the clamping sleeve 322, thereby achieving the adjustment of the position of the wheel 32 on the chassis assembly 1 along the axial direction of the wheel 32; at the same time, it also avoids affecting the normal driving of the wheel 32. Moreover, the clamping sleeve 322 can clamp the connecting shaft 31 at any position during the sliding process, so that the wheel 32 can be detachably fixedly connected to the chassis assembly 1 at any position during the sliding process, and the stepless position adjustment of the wheel 32 can be achieved, further improving the adaptability of the photovoltaic module transport device to the roof 01 and further expanding the scope of use of the photovoltaic module transport device.

[0133] To facilitate installation, disassembly and maintenance, the clamping sleeve 322 and the wheel body 321 can be selected to be detachably fixedly connected. For example, the clamping sleeve 322 and the wheel body 321 are fixedly connected by a first screw 3222. In this case, the wheel body 321 has a fixing hole 32111 that cooperates with the first screw 3222; or, the clamping sleeve 322 and the wheel body 321 are detachably fixedly connected by a snap-fit structure or a magnetic structure, etc., which is not limited to the embodiments of the present application.

[0134] To facilitate the gripping sleeve 322's ability to grip and release the connecting shaft 31, the gripping sleeve 322 is designed to be an open ring. The gripping sleeve 322 is elastic, allowing the ends of the gripping sleeve 322 on either side of the opening 3224 to move toward and away from each other. Furthermore, the ends of the gripping sleeve 322 on either side of the opening 3224 are detachably fixedly connected. Thus, by releasing the fixed connection between the ends of the gripping sleeve 322 on either side of the opening 3224, the gripping sleeve 322 releases the connecting shaft 31; by reconnecting the ends of the gripping sleeve 322 on either side of the opening 3224, the gripping sleeve 322 grips the connecting shaft 31.

[0135] The ends of the holding sleeve 322 on both sides of the opening 3224 can be detachably fixedly connected by second screws 3223. Of course, the ends of the holding sleeve 322 on both sides of the opening 3224 can be detachably fixedly connected by means of snap connection, magnetic attraction, etc., which is not limited in this embodiment of the present application.

[0136] In practical applications, the clamping sleeve 322 can also be configured in other shapes. For example, the clamping sleeve 322 may include two clamping plates, each fixedly connected to the wheel body 321. Each clamping plate has a groove. The grooves of the two clamping plates are joined to form a receiving portion for the connecting shaft 31. The two clamping plates are joined and the ends of the two clamping plates are detachably connected. Releasing the fixed connection between the two clamping plates, separating them, releases the connecting shaft 31; and fixing the two clamping plates together secures the connecting shaft 31.

[0137] In the embodiment of the present application, the clamping sleeve 322 can also be replaced by other structures that can limit the wheel body 321, and is not limited to the above-mentioned structure of the clamping sleeve 322.

[0138] When the adjusting wheel 32c is the driven wheel 32b, the driven wheel 32b and the driven shaft 31b can be connected in transmission, the driven shaft 31b is rotatably set on the driven bracket 233, and the driven bracket 233 is fixed on the chassis assembly 1; or, the driven wheel 32b is rotatably set on the driven shaft 31b, the driven shaft 31b is fixed on the driven bracket 233, and the driven bracket 233 is fixed on the chassis assembly 1.

[0139] When the adjustment wheel 32c is the driving wheel 32a, the driving wheel 32a is connected to the driving shaft 31a, and the driving mechanism 2 drives the driving shaft 31a to rotate. Figure 1 、 Figure 4 and Figure 5 As shown, the transmission mechanism 22 is a belt transmission mechanism, and the driving assembly 21 drives the driving shaft 31a to rotate through the belt transmission mechanism.

[0140] For example, Figure 5As shown, the belt transmission mechanism includes a driving wheel 222, a driven wheel 223 and a belt 221. The belt 221 is wound around the driving wheel 222 and the driven wheel 223. The output shaft of the driving assembly 21 is in transmission connection with the driving wheel 222, and the driven wheel 223 is in transmission connection with the driving shaft 31a. The driven wheel 223 is rotatably arranged on the driven bracket 233 through the first bearing 35. Figure 5 and Figure 6 As shown, the driving shaft 31a is connected to the driving wheel 32a through the second transmission key 38, and the driving shaft 31a is connected to the driven wheel 223 through the third transmission key 34. The type of the third transmission key 34 is consistent with the type of the second transmission key 38. For example, the third transmission key 34 and the second transmission key 38 are both flat keys or splines. In the case that the third transmission key 34 and the second transmission key 38 are both splines, the third transmission key 34 and the second transmission key 38 are an integrated structure.

[0141] In the above-mentioned driving mechanism 2, the driving assembly 21 drives the driving shaft 31a to rotate through the transmission mechanism, so that the driving assembly 21 deviates from the driving shaft 31a, thereby facilitating adjustment of the position of the driving wheel 32a on the driving shaft 31a.

[0142] In actual situations, the driving assembly 21 can also drive the driving shaft 31 a to rotate through other transmission mechanisms such as a chain transmission mechanism, a gear transmission mechanism, etc., and is not limited to a belt transmission mechanism.

[0143] During the movement of the photovoltaic module transport device, the wheels 32 move along the top surface of the guide rail 02. Since the top surface area of the guide rail 02 is small, the wheels 32 are more likely to deviate from the guide rail 02 for normal movement of the photovoltaic module transport device. In order to improve the reliability of the photovoltaic module transport device moving along the guide rail 02, as shown in FIG. Figure 10-12 As shown, the wheel 32 includes a wheel body 3211 and a limiting flange 3212. The wheel body 3211 is used to contact the top of the guide rail 02. The limiting flange 3212 is fixedly connected to the wheel body 3211. The limiting flange 3212 is located at one or both ends of the wheel body 3211 in the axial direction. The limiting flange 3212 is used to limit the position of the wheel 32 in the axial direction of the guide rail 02. In this way, the wheel 32 itself and the guide rail 02 are used to limit the position of the wheel 32 in the axial direction of the wheel 32. This reduces the probability of the wheel 32 deviating from the guide rail 02, ensures that the wheel 32 moves along the top surface of the guide rail 02, and improves the reliability of the photovoltaic module transport device moving along the guide rail 02.

[0144] When the limiting flange 3212 is located at one end of the wheel body 3211 in the axial direction, Figure 10As shown, in two wheels 32 that are distributed sequentially and adjacent to each other in the axial direction of the wheel 32, the limiting flanges 3212 are distributed between the two guide rails 02 corresponding to the above two wheels 32; or, in two wheels 32 that are distributed sequentially and adjacent to each other in the axial direction of the wheel 32, the limiting flanges 3212 are distributed outside the two guide rails 02 corresponding to the above two wheels 32; or, in two wheels 32 that are distributed sequentially and adjacent to each other in the axial direction of the wheel 32, the limiting flange 3212 of one wheel 32 is distributed outside the two guide rails 02 corresponding to the above two wheels 32, and the limiting flange 3212 of the other wheel 32 is distributed between the two guide rails 02 corresponding to the above two wheels 32.

[0145] It should be noted that, when the limiting flange 3212 is located at one axial end of the wheel body 3211 , the wheel 32 can be understood as a T-shaped wheel.

[0146] In the case of the limiting flanges 3212 at the axial ends of the wheel body 3211, the two limiting flanges 3212 of the two wheels 32 are distributed between the two guide rails 02 corresponding to the above two wheels 32, and the other two limiting flanges 3212 of the two wheels 32 are distributed outside the two guide rails 02 corresponding to the above two wheels 32.

[0147] In order to facilitate drainage, the roof 01 can be tilted so that one of the two adjacent guide rails 02 is higher than the other. Of course, the roof 01 can also be horizontally arranged, in which case one of the two adjacent guide rails 02 can also be higher than the other.

[0148] like Figure 10 As shown, the guide rail 02 at section B is lower than the guide rail 02 at section C. As the PV module transport device moves along two guide rails 02 at different heights, the wheels 32 are more likely to detach from the higher guide rail 02, causing the PV module transport device to tip over to the lower side, potentially damaging the PV modules 03 and compromising transport safety. To address this issue, the limiting flange 3212 of at least one wheel 32 is positioned on the higher side of the corresponding guide rail 02 to prevent the PV module transport device from tipping over to the lower side. In this way, when the photovoltaic module transport device has a tendency to overturn to the lower side, the limiting flange 3212 distributed on the higher side of the guide rail 02 cooperates with the guide rail 02 to limit the movement of the wheel 32 itself to the lower side, avoiding the wheel 32 from leaving the higher guide rail 02, thereby limiting the photovoltaic module transport device from overturning to the lower side, effectively reducing the risk of derailment of the wheel 32 and the risk of overturning of the photovoltaic module transport device, and improving the transportation safety of the photovoltaic module transport device.

[0149] It should be noted that, when the wheel 32 includes a wheel body 321 and a clamping sleeve 322 , the wheel body 321 may include a wheel main body 3211 and a limiting flange 3212 .

[0150] For example, Figure 10-12 As shown, in two axially adjacent wheels 32, the limiting flanges 3212 of the two wheels 32 are located between the two guide rails 02 corresponding to the wheels 32. Figure 11 The wheel 32 shown in FIG is the right wheel. Figure 12 The wheel 32 shown in the figure is the left wheel, and the limiting flange 3212 in the right wheel is distributed on the higher side of the guide rail 02 corresponding thereto, limiting the positive axial movement of the right wheel (movement to the right), thereby limiting the left wheel from moving to the right, limiting the left wheel from separating from the guide rail corresponding thereto, and further limiting the photovoltaic module transport device from tipping over to the lower side. The limiting flange 3212 in the left wheel is distributed on the lower side of the guide rail 02 corresponding thereto, limiting the reverse axial movement of the left wheel (movement to the left). Of course, it is also possible to choose that the limiting flange 3212 in the right wheel is distributed on the lower side of the guide rail 02 corresponding thereto, and the limiting flange 3212 in the left wheel is distributed on the higher side of the guide rail 02 corresponding thereto, and is not limited to Figure 10-12 shown.

[0151] In the wheel 32, the limiting flange 3212 and the wheel body 3211 can be an integrated structure or a split structure. In order to simplify installation and improve limiting reliability, the limiting flange 3212 and the wheel body 3211 can be an integrated structure.

[0152] To facilitate determining whether the wheels 32 are adjusted to the desired position, the chassis assembly 1 may optionally be provided with wheel position indicators 14 corresponding to each wheel 32. The wheel position indicators 14 are used to indicate the position of the wheel 32. It should be noted that the wheel position indicators 14 can indicate each position of the wheel 32. Thus, the wheel position indicators 14 can also indicate the adjustment of the wheel 32.

[0153] For example, if there are four wheels 32 , wheel position indication marks 14 are provided at four positions of the chassis assembly 1 , namely, front, rear, left, and right, and the four positions correspond to the four wheels 32 one by one.

[0154] The wheel position indicator may include at least one of an indicator line, an indicator arrow, or an indicator number. To facilitate accurate determination of the position of wheel 32, the wheel position indicator may include at least one indicator line, with multiple indicator lines equally spaced. The distance between two adjacent indicator lines is determined based on practical circumstances and is not limited in this embodiment.

[0155] In the embodiment of the present application, the drive mechanism 2 is a bidirectional drive mechanism, which enables the drive mechanism 2 to drive the active wheel 32a to rotate in both directions, thereby enabling the chassis assembly 1 to move in both directions. In this way, the drive direction of the drive mechanism 2 can be selected according to actual conditions, thereby improving the ease of use and versatility of the photovoltaic module transport device.

[0156] In the above embodiment, the drive mechanism 2 can be disposed at one end of the chassis assembly 1 in the direction of movement. The drive mechanism 2 is located on the bottom side of the chassis assembly 1, so that the photovoltaic module transport device can have either a front-wheel drive or a rear-wheel drive structure. To facilitate both front-wheel drive and rear-wheel drive, the wheels 32 of the wheel assembly 3 of the photovoltaic module transport device can be symmetrically distributed in the front-to-back direction.

[0157] In some other embodiments, the driving mechanism 2 may also be selected as a unidirectional driving mechanism, which is not limited to the above embodiment.

[0158] like Figure 1 As shown, in some embodiments, a safety touch edge 4 and a buffer bracket 5 are provided at the front end of the chassis assembly 1; wherein, the safety touch edge 4 is connected to the chassis assembly 1 through the buffer bracket 5.

[0159] It should be noted that the driving direction is the forward or reverse direction of the moving direction of the chassis assembly 1 .

[0160] The safety touch edge 4 is in an elongated strip shape, and the length direction of the safety touch edge 4 is parallel to the length direction of the wheel 32 .

[0161] The safety edge 4 is electrically connected to the controller 7 of the PV module transporter, which is used to control the operation of the PV module transporter. The controller 7 can be understood as the main control cabinet or main controller of the PV module transporter. The controller 7 can also be understood as the central control device within the intelligent control or automated control system of the PV module transporter, which has system data processing, gateway communication connection, and centralized control capabilities.

[0162] The aforementioned safety edge 4 is a pressure-sensitive switch in the form of a rubber band. When compressed, it generates an electrical signal indicating a current change and transmits it to the controller 7. Based on this electrical signal, the controller 7 controls the PV module transporter to an emergency stop, protecting the PV modules 03 and achieving obstacle avoidance for the PV module transporter. In practice, the controller 7 can achieve this by controlling the drive mechanism 2 to an emergency stop.

[0163] The above embodiment realizes the obstacle avoidance protection of the volt component transport device; at the same time, the safety touch edge 4 is connected to the chassis assembly 1 through the buffer bracket 5. When the safety touch edge 4 is compressed, the buffer bracket 5 can play a buffering role, avoiding serious damage to the safety touch edge 4 and improving the obstacle avoidance protection performance.

[0164] In order to facilitate installation, disassembly and maintenance, the safety touch edge 4 and the buffer bracket 5 can be detachably connected, and / or the buffer bracket 5 and the chassis assembly 1 can be detachably connected. Among them, screws or other methods can be used to achieve detachable connection, which is not limited in this embodiment of the application.

[0165] The specific structure of the buffer bracket 5 can be selected according to actual conditions, so as to ensure that the buffer bracket 5 has a buffering performance. Exemplarily, the buffer bracket 5 includes a bent plate, which can be a special-shaped sheet metal bracket or other regular sheet metal bracket.

[0166] The bending structure of the above-mentioned bending plate is designed according to actual needs. For example, the bending structure includes a right-angle bending structure and / or an arc-shaped bending structure, etc. The embodiments of the present application do not simplify this.

[0167] In order to improve the buffering performance of the buffer bracket 5, at least two buffer brackets 5 can be selected and distributed in sequence along the length direction of the safety touch edge 4. The shapes of the at least two buffer brackets 5 can be the same or different, depending on the actual situation.

[0168] For example, Figure 3 As shown, there are five buffer brackets 5 , four of which have the same structure, and another buffer bracket 5 has a structure different from that of the other four buffer brackets 5 .

[0169] Of course, it is possible to select only one buffer bracket 5 in an elongated strip shape, with the length direction of the buffer bracket 5 being parallel to the length direction of the safety touch edge 4 .

[0170] The material of the buffer bracket 5 is selected according to the actual situation. In order to reduce the weight of the buffer bracket 5 and improve the transportation convenience, the buffer bracket can be selected to be a lightweight material component. For the description of lightweight material components, please refer to the previous text and will not be repeated here.

[0171] When the driving mechanism 2 is a bidirectional driving mechanism, in order to achieve bidirectional obstacle avoidance protection, the safety contact edges 4 are located at both ends of the chassis assembly 1 in the moving direction. Correspondingly, the buffer brackets 5 are also distributed at both ends of the chassis assembly 1 in the moving direction.

[0172] In actual situations, the safety touch edge 4 may be fixedly connected to the chassis assembly 1 via a rigid bracket, or the safety touch edge 4 may be directly fixedly connected to the chassis assembly 1 , and the present invention is not limited to the above embodiments.

[0173] In some embodiments, as Figure 1 and Figure 2As shown, the photovoltaic module transport device also includes a detector assembly 6, which includes a detection bracket and a detector 61. The detection bracket is mounted on the chassis assembly 1, and the detector 61 is mounted on the detection bracket. The detector 61 is electrically connected to the controller 7 of the photovoltaic module transport device. For a description of the controller 7, please refer to the previous text and will not be repeated here.

[0174] On the one hand, detector 61 is used to detect obstacles in front of chassis assembly 1. Thus, when detector 61 detects an obstacle, controller 7 controls the photovoltaic module transporter to an emergency stop, enabling the photovoltaic module transporter to implement obstacle avoidance and protection, thereby protecting both the photovoltaic module transporter and photovoltaic modules 03. In this case, the photovoltaic module transporter also includes a safety edge 4, thus achieving dual obstacle avoidance. In the event of failure of the safety edge 4 or detector 61, the photovoltaic module transporter still maintains its obstacle avoidance function, effectively improving the photovoltaic module transporter's obstacle avoidance performance.

[0175] On the other hand, the detector 61 is used to detect the position of the chassis assembly 1. In this way, the controller 7 and the detector 61 cooperate to enable the photovoltaic assembly transport device to automatically reach the required position, thereby improving the degree of automation of the photovoltaic assembly transport device.

[0176] In actual situations, the above two aspects can be implemented simultaneously or separately, and the embodiments of the present application do not limit this.

[0177] The type of detector 61 is selected according to actual conditions. For example, the detector 61 is a radar detector, which enables the detector 61 to have higher detection accuracy. Of course, the detector 61 can also be an ultrasonic sensor, a visual sensor, an infrared sensor, or a laser sensor, etc., which is not limited in this embodiment of the present application.

[0178] In the photovoltaic module transport device described above, the pitch angle of the detector 61 relative to the moving direction of the chassis assembly 1 affects the detection effect of the detector 61. To ensure the detection effect of the detector 61, the pitch angle of the detector 61 relative to the moving direction of the chassis assembly 1 is adjustable. To facilitate adjustment of the pitch angle, a detection bracket can be selected to adjust the pitch angle of the detector 61 relative to the moving direction of the chassis assembly 1.

[0179] For installation, disassembly and maintenance, the detector 61 can be detachably mounted on the detection bracket, and / or the detection bracket can be detachably mounted on the chassis assembly 1. The detachable mounting can be achieved by screws or other components or structures, which is not limited in this embodiment of the present application.

[0180] The specific structure of the detection bracket is selected based on actual conditions. In some embodiments, the detection bracket includes: an adjustment bracket 62 and a mounting plate 63; wherein two adjustment brackets 62 are arranged in sequence along the axial direction of the wheel 32; one end of the adjustment bracket 62 is fixedly connected to the chassis assembly 1, and the other end of the adjustment bracket 62 has a clamping portion; the mounting plate 63 is located between the two adjustment brackets 62, and the detector 61 is mounted on the mounting plate 63; the mounting plate 63 is connected to the clamping portion.

[0181] The clamping portion has a clamping state and an adjustable state. In the adjustable state, the mounting plate 63 and the clamping portion are hingedly connected to allow the pitch angle of the mounting plate 63 to be adjusted. In the clamping state, the clamping portion and the mounting plate 63 are fixedly connected. It should be noted that the pitch angle of the mounting plate 63 is the pitch angle of the detection bracket.

[0182] The specific structure of the clamping portion is selected according to actual conditions. In some embodiments, the clamping portion includes a first clamping plate 621 and a second clamping plate 622, and the first ends of the first clamping plate 621 and the second clamping plate 622 are fixedly connected to one end of the adjustment frame 62. The first clamping plate 621 and the second clamping plate 622 are both provided with grooves, and the grooves of the first clamping plate 621 and the second clamping plate 622 are connected to form a mounting hole for accommodating a rotating shaft, and the rotating shaft is fixed to the mounting plate 63, and the axial direction of the rotating shaft is parallel to the axial direction of the wheel 32; the second ends of the first clamping plate 621 and the second clamping plate 622 are detachably fixedly connected, for example, the second ends of the first clamping plate 621 and the second clamping plate 622 are fixedly connected by screws. In this way, the fixed connection between the second ends of the first clamping plate 621 and the second clamping plate 622 is released, so that the mounting hole formed by the two grooves releases the rotating shaft, and the rotating shaft can rotate in the mounting hole, so that the clamping part is in an adjustable state; the second ends of the first clamping plate 621 and the second clamping plate 622 are fixedly connected, so that the first clamping plate 621 and the second clamping plate 622 clamp the rotating shaft, and the rotating shaft cannot rotate in the mounting hole, so that the clamping part is in a clamping state.

[0183] Of course, the clamping portion may also have other structures and is not limited to the above structure.

[0184] To extend the service life of the detector 61, the detector assembly 6 further includes a protective cover 64, which is disposed on the top of the detector 61. The protective cover 64 can also be fixed to the adjustment frame 62. Thus, the protective cover 64 protects the detector 61, thereby extending the service life of the detector 61.

[0185] In the case where the driving mechanism 2 is a bidirectional driving mechanism, in order to achieve bidirectional detection, the detector assemblies 6 are located at both ends of the chassis assembly 1 in the moving direction of the chassis assembly 1 .

[0186] In the embodiment of the present application, when the photovoltaic component transport device includes a buffer bracket 5, at least one buffer bracket 5 can be selected to have an avoidance space, and the detector component 6 is located in the avoidance space.

[0187] like Figure 1 and Figure 3 As shown, in some embodiments, the photovoltaic module transport device further includes a power battery 8, which is disposed on the chassis assembly 1 and is used to provide power to the photovoltaic module transport device. For example, when the drive mechanism 2 is an electric drive mechanism, the power battery 8 is used to power the drive mechanism 2; when the photovoltaic module transport device includes a controller 7, the power battery 8 is used to power the controller 7; when the photovoltaic module transport device includes a safety contact edge 4, the power battery 8 is used to power the safety contact edge 4; and when the photovoltaic module transport device includes a detector 61, the power battery 8 is used to power the detector 61.

[0188] like Figure 1 and Figure 3 As shown, in some embodiments, the photovoltaic module transport device further includes a debugger 9, which is disposed on the chassis assembly 1 and is used to debug and troubleshoot the photovoltaic module transport device. This allows for debugging and troubleshooting of the photovoltaic module transport device, thereby improving its performance.

[0189] In the above embodiment, the power battery 8 can power the debugger 9. The specific structure of the debugger 9 is selected according to actual conditions and is not limited in the embodiment of the present application.

[0190] like Figure 1 and Figure 3 As shown, in some embodiments, the photovoltaic module transport device further includes an auxiliary control console 10, which is provided on the chassis assembly 1 and is used to perform auxiliary control on the photovoltaic module transport device. It should be noted that the controller 7 performs the main control on the photovoltaic module transport device.

[0191] The auxiliary control panel 10 has an operating portion for the staff to operate. In order to facilitate the staff's operation, the auxiliary control panel 10 has a set height. The set height is in line with ergonomics and improves the operating comfort of the auxiliary control panel 10.

[0192] In the above embodiment, the power battery 8 can supply power to the auxiliary console 10. The specific structure of the auxiliary console 10 can be selected according to actual conditions and is not limited in the embodiment of the present application.

[0193] In the embodiment of the present application, the specific structure of the chassis assembly 1 is selected according to the actual situation. Figure 1 and Figure 3In some embodiments, the chassis assembly 1 includes: a chassis frame 11, and a supporting component 13 arranged on the chassis frame 11; wherein the supporting component 13 is used to place the photovoltaic component 03, and the driving mechanism 2 and the connecting shaft 31 are both arranged on the chassis frame 11.

[0194] The chassis frame 11 plays a supporting role. The specific structure and shape of the chassis frame 11 are selected according to actual conditions. For example, the chassis frame is a "field"-shaped structure.

[0195] For ease of production and use, the chassis frame 11 can be selected to have an axisymmetric structure, and the axisymmetric structure can have one or two axes of symmetry. For example, one axis of symmetry of the axisymmetric structure can be parallel to the movement direction of the chassis assembly 1, and / or one axis of symmetry of the axisymmetric structure can be parallel to the axial direction of the wheel 32.

[0196] In the case where one axis of symmetry of the axisymmetric structure can be parallel to the axial direction of the wheel 32, both ends of the chassis frame 11 can serve as the front ends, thereby facilitating bidirectional transportation of the photovoltaic module transport device.

[0197] The material of the chassis frame 11 is selected according to the actual situation. In order to reduce the weight of the chassis frame 11 and improve the transportation convenience, the chassis frame 11 can be selected to be a lightweight material component. For the description of the lightweight material component, please refer to the above text and will not be repeated here.

[0198] There can be one or more supporting components 13, which can be selected based on actual conditions and is not limited in the embodiment of the present application.

[0199] In practical applications, photovoltaic modules 03 can be manually placed on support member 13. To facilitate manual placement of photovoltaic modules 03, support member 13 has a set height. This set height is ergonomic and improves the comfort of manual placement of photovoltaic modules 03. To ensure that the height of support member 13 meets the required height, support member 13 can be optionally mounted on chassis frame 11 via support columns 12. This allows the height of support member 13 to be controlled by controlling the height of support columns 12.

[0200] In the above structure, the controller 7, power battery 8, debugger 9, and auxiliary console 10 are all lower than the support member 13. In this way, the controller 7, power battery 8, debugger 9, and auxiliary console 10 can be distributed in the chassis frame 11 in the area corresponding to the photovoltaic module 03. In this way, the controller 7, power battery 8, debugger 9, and auxiliary console 10 are all located on the bottom side of the photovoltaic module 03, which improves the structural compactness of the photovoltaic module transport device, reduces the floor space of the entire photovoltaic module transport device (the area occupied by the roof 01), and facilitates the transportation of the photovoltaic module 03 on the roof 01. To facilitate the operation of the auxiliary console 10, the auxiliary console 10 can be located at the edge of the chassis frame 11.

[0201] In order to reduce the probability of damage to the photovoltaic module 03, the support member 13 can be selected as a buffer. In this way, the support member 13 can have impact resistance and energy absorption functions. It should be noted that the strength of the support member 13 needs to meet the requirements.

[0202] Exemplarily, the supporting component 13 is a polyurethane component, a rubber component, a silicone component, etc., which is not limited in the embodiment of the present application.

[0203] Multiple photovoltaic modules 03 need to be stacked on the support component 13. In order to facilitate the placement of the photovoltaic modules 03, the support component 13 can limit the bottom photovoltaic module 03 in the moving direction of the chassis component 1. Figure 3 and Figure 13 As shown, in some embodiments, at least one support component 13 is a first support component 13a, and at least one support component 13 is a second support component 13b. The first support component 13a and the second support component 13b are distributed in sequence along the moving direction of the chassis component 1, and the first support component 13a and the second support component 13b are both provided with a component limiting portion 131; the component limiting portion 131 of the first support component 13a and the component limiting portion 131 of the second support component 13b cooperate to limit the photovoltaic component 03 in contact with the component limiting portion 131 in the moving direction.

[0204] In order to simplify the structures of the first supporting member 13a and the second supporting member 13b, the first supporting member and the second supporting member can be selected to be U-shaped. In this way, it can also be applicable to the case where the driving mechanism 2 is a bidirectional driving mechanism.

[0205] The number of first support members 13a and second support members 13b is selected based on practical needs. To improve support stability, there are at least two first support members 13a, distributed sequentially along the axial direction of the wheel 32; and / or there are at least two second support members 13b, distributed sequentially along the axial direction of the wheel 32.

[0206] A method for using the photovoltaic module transport device provided in an embodiment of the present application is as follows:

[0207] According to the guide rail spacing between two adjacent guide rails 02 on the roof 01 and based on the centering of the chassis frame 11 relative to the guide rail 02, according to the wheel position indicator 14 on the chassis frame 11, release the fixed connection of the ends of the clamping sleeve 322 on both sides of the opening, so that the clamping sleeve 322 releases the connecting shaft 31, and adjust the axial position of the wheel 32. After the adjustment, the ends of the clamping sleeve 322 on both sides of the opening are fixedly connected, so that the clamping sleeve 322 clamps the connecting shaft 31. The wheel 32 and the connecting shaft 31 are relatively fixed in the axial direction. The photovoltaic module transport device is placed on the guide rail 02. The wheel 32 and the guide rail 02 are matched at the axial upper limit of the wheel 32. That is, the preparation work is completed;

[0208] Then, test whether the electrical components of the photovoltaic module transport device are functioning normally, debug the software functions, and conduct a no-load operation test of the photovoltaic module transport device on the guide rail 02. After the test is normal, the preparation phase ends;

[0209] Then, the photovoltaic module transport device is put into use, and the photovoltaic module 03 is manually placed on the chassis module 1. The photovoltaic module transport device automatically runs to the destination and stops, and the photovoltaic module 03 is manually removed. At the same time, during the automatic transportation process, the detector module 6 and the safety touch edge 4 play an obstacle avoidance role, which can perform double obstacle avoidance and improve the safety protection performance.

[0210] It can be seen from the above-mentioned usage method that the above-mentioned photovoltaic component transportation device is easy to use.

[0211] In actual situations, the above-mentioned usage method can be adjusted accordingly according to changes in the structure of the photovoltaic module transportation device, and is not limited to the above-mentioned usage method.

[0212] In order to adjust the position of the wheel 32 on the chassis assembly 1 along the axial direction of the wheel 32, the position of the connecting shaft 31 on the chassis assembly 1 can also be adjusted along the axial direction of the wheel 32. This solution is specifically described below through Example 2.

[0213] Example 2

[0214] like Figure 14 and Figure 17 As shown, the photovoltaic module transportation device provided in the embodiment of the present application includes a chassis assembly 1, a drive mechanism 2 and a wheel assembly 3.

[0215] In the second embodiment of the present application, for the chassis assembly 1, reference can be made to the first embodiment, which will not be repeated here.

[0216] In the second embodiment of the present application, the wheel assembly 3 includes a connecting shaft 31 and a wheel 32. For the description of the connecting shaft 31 and the connection between the wheel 32 and the connecting shaft 31, please refer to the first embodiment and will not be repeated here.

[0217] In the second embodiment of the present application, at least one wheel 32 is a driving wheel 32a, and at least one wheel 32 is a driven wheel 32b. The driving wheel 32a includes a wheel body 321. The specific structures of the wheel body 321 and the driven wheel 32b can be referred to in the first embodiment and will not be repeated here.

[0218] In the second embodiment of the present application, the specific type of the driving mechanism 2 is selected according to actual conditions.

[0219] In the second embodiment of the present application, Figure 15 and Figure 18 As shown, the driving shaft 31a is the adjustment shaft 31c, both ends of the adjustment shaft 31c are arranged on the adjustment bracket 24, the adjustment bracket 24 and the chassis assembly 1 are detachably fixedly connected, and the position of the adjustment bracket 24 on the chassis assembly 1 is adjustable along the axial direction of the adjustment shaft 31c.

[0220] When the chassis assembly 1 includes the chassis frame 11 , the adjustment bracket 24 and the chassis frame 11 are detachably fixedly connected, and the position of the adjustment bracket 24 on the chassis frame 11 is adjustable along the axial direction of the adjustment shaft 31 c .

[0221] When the fixed connection between the adjustment bracket 24 and the chassis assembly 1 is removed, the adjustment bracket 24 and the chassis assembly 1 can slide relative to each other along the axial direction of the adjustment shaft 31c, and the adjustment bracket 24 can be detachably fixedly connected to the chassis assembly 1 at multiple positions during the sliding process, thereby achieving adjustable position of the adjustment bracket 24 on the chassis assembly 1 along the axial direction of the adjustment shaft 31c.

[0222] In order to achieve the position of the adjustment bracket 24 on the chassis assembly 1 being adjustable along the axial direction of the adjustment shaft 31c, as shown in FIG. Figure 15 、 Figure 16 、 Figures 18-20 As shown, in the first aspect, the adjustment bracket 24 can be selected to be fixed to the chassis assembly 1 by means of bolts 25 and nuts 26; wherein, the chassis assembly 1 is provided with a slide groove 15, and the length direction of the slide groove 15 is the axial direction of the adjustment shaft 31c; the adjustment bracket 24 is provided with a bracket fixing hole 244 that cooperates with the bolt 25, and the head of the bolt 25 is located in the slide groove 15 and slides with the slide groove 15, and the head of the bolt 25 and the slide groove 15 are upper-limited in the depth direction of the slide groove 15, and the head of the bolt 25 is distributed at one end of the bracket fixing hole 244, and the bolt 25 passes through the bracket fixing hole 244, and the nut 26 is distributed at the other end of the bracket fixing hole 244.

[0223] It should be noted that the depth direction of the sliding groove 15 is the axial direction of the nut 26 and also the axial direction of the bolt 25 .

[0224] The structure of the chute 15 is selected according to the actual situation. For example, the chute 15 is a dovetail groove, a T-slot or a Figure 15 The shape shown, etc., only needs to ensure that "the bolt and the slide groove 15 are slidably matched, the nut is located in the slide groove 15 and can move along the slide groove 15, and the nut and the slide groove 15 are limited in the depth direction of the slide groove 15".

[0225] The adjustment method of the adjustment bracket 24 in the above structure is: when the position of the bracket 24 needs to be adjusted, loosen the nut 26 to loosen the connection between the bolt 25 and the nut 26, and the fixed connection between the adjustment bracket 24 and the chassis assembly 1 at both ends of the adjustment shaft 31c is removed. The adjustment bracket 24 can be moved axially along the adjustment shaft 31c, and the bolt 25 and the nut 26 move synchronously with the adjustment bracket 24. After the adjustment bracket 24 moves to the set position, tighten the nut 26 to fix the adjustment bracket 24 and the chassis assembly 1.

[0226] It should be noted that during the process of tightening the nut 26, a tool can be used to act on the bolt 25 to prevent the bolt 25 from rotating. In this case, there is a manipulation space near the head or tail of the bolt 25 to ensure that the tool acts on the bolt 25; alternatively, the slide groove 15 and the bolt 25 cooperate to limit the circumference of the bolt 25 to prevent the bolt 25 from rotating.

[0227] Secondly, the adjustment bracket 24 is fixed to the chassis assembly 1 by means of bolts 25 and nuts 26. The chassis assembly 1 is provided with a strip hole, the length direction of which is the axial direction of the adjustment shaft 31c. The adjustment bracket 24 is provided with a bracket fixing hole 244 that cooperates with the bolt 25.

[0228] In the above structure, the adjustment method of the adjustment bracket 24 is consistent with the adjustment method described above and will not be repeated here.

[0229] Thirdly, the adjustment bracket 24 is fixed to the chassis assembly 1 by means of bolts 25 and nuts 26. The chassis assembly 1 is provided with a plurality of adjustment holes sequentially distributed along the axial direction of the adjustment shaft 31c; the bolts 25 pass through the adjustment holes.

[0230] In the above structure, the adjustment method of the adjustment bracket 24 is consistent with the adjustment method described above and will not be repeated here.

[0231] In the three aspects described above, the positions of the bolt 25 and the nut 26 are interchangeable. After this interchange, the nut 26 is located within the chute 15 and can move along the chute 15. The nut 26 and the chute 15 are engaged at the upper limit position in the depth direction of the chute 15. In this case, while tightening the bolt 25, a tool can be used to act on the nut 26 to prevent it from rotating. In this case, there is room for manipulation near the nut 26 to ensure that the tool can act on the nut 26; alternatively, the chute 15 and the nut 26 are engaged at the upper limit position in the circumferential direction of the nut 26 to prevent it from rotating.

[0232] In order to facilitate production and manufacturing, the chassis frame 11 may include aluminum profiles, which are convenient for forming the slide groove 15. Therefore, the first aspect may be preferred.

[0233] The specific structure of the adjustment bracket 24 is selected according to actual conditions.

[0234] like Figure 15 As shown, the adjustment bracket 24 includes: a first bracket sub-plate 241 and a second bracket sub-plate 242; wherein, one end of the adjustment shaft 31c is arranged on the first bracket sub-plate 241, and the other end of the adjustment shaft 31c is arranged on the second bracket sub-plate 242; the first bracket sub-plate 241 and the chassis assembly 1 are detachably fixedly connected, and the position of the first bracket sub-plate 241 on the chassis assembly 1 is adjustable along the axial direction of the adjustment shaft 31c; the second bracket sub-plate 242 and the chassis assembly 1 are detachably fixedly connected, and the position of the second bracket sub-plate 242 on the chassis assembly 1 is adjustable along the axial direction of the adjustment shaft 31c.

[0235] The first bracket sub-plate 241 can adopt the structures described in the first, second, and third aspects above to achieve adjustable position on the chassis assembly 1 along the axial direction of the adjustment shaft 31 c. Correspondingly, the second bracket sub-plate 242 can adopt the structures described in the first, second, and third aspects above to achieve adjustable position on the chassis assembly 1 along the axial direction of the adjustment shaft 31 c.

[0236] like Figure 15 and Figure 16 As shown, to ensure the installation of bolt 25 and nut 26, both the first bracket sub-plate 241 and the second bracket sub-plate 242 are provided with bracket mounting holes 245, which are connected to the bracket fixing hole 244. When the head of bolt 25 is located in the chute 15, bracket mounting holes 245 provide space for installing bolt 25 and nut 26 and tightening nut 26; when nut 26 is located in the chute 15, bracket mounting holes 245 provide space for installing bolt 25 and tightening bolt 25.

[0237] The bracket mounting hole 245 can be circular, quadrilateral or other shapes, which is not limited in the embodiment of the present application.

[0238] In order to facilitate the movement of the first bracket sub-plate 241 and the second bracket sub-plate 242 , both the first bracket sub-plate 241 and the second bracket sub-plate 242 are provided with bracket limiting grooves 246 , which are limitedly matched with the chassis frame 11 .

[0239] Of course, the first bracket sub-plate 241 and the second bracket sub-plate 242 may also not be provided with the bracket limiting groove 246 , and are not limited to the above structure.

[0240] like Figure 18 and Figure 19 As shown, the adjustment bracket 24 includes: a first bracket sub-plate 241, a second bracket sub-plate 242, and a connecting plate 243 connecting the first bracket sub-plate 241 and the second bracket sub-plate 242; wherein, one end of the adjustment shaft 31c is set on the first bracket sub-plate 241, and the other end of the adjustment shaft 31c is set on the second bracket sub-plate 242, the connecting plate 243 and the chassis assembly 1 are detachably fixedly connected, and the position of the connecting plate 243 on the chassis assembly 1 is adjustable along the axial direction of the adjustment shaft 31c.

[0241] The connecting plate 243 can adopt the structures described in the first, second and third aspects above to achieve an adjustable position on the chassis assembly 1 along the axial direction of the adjustment shaft 31 c.

[0242] In actual situations, the adjustment bracket 24 can also be Figure 18 On the basis of the structure shown, other structures are added, for example, another plate is added and arranged parallel to the first bracket sub-plate 241 and the second bracket sub-plate 242. The plate is located between the first bracket sub-plate 241 and the second bracket sub-plate 242. The structure of the plate is the same as that of the first bracket sub-plate 241 and the second bracket sub-plate 242, and is not limited to the above two structures.

[0243] In the second embodiment of the present application, the driving mode of the driving mechanism 2 is selected according to the actual situation. Figure 15 As shown, the driving mechanism 2 drives the active wheel 32a to rotate through the adjusting shaft 31c.

Both ends of the adjusting shaft 31c are rotatably provided on the adjusting bracket 24.

[0244] Because both the drive mechanism 2 and the adjustment shaft 31c are supported by the adjustment bracket 24, the drive mechanism 2 should be as simple in structure, as small in size, and as light in weight as possible. Therefore, the drive mechanism 2 includes a drive component 211 and a reduction mechanism 212. The drive component 211 drives the adjustment shaft 31c to rotate via the reduction mechanism 212, which is a gear reduction mechanism.

[0245] Of course, without considering the volume and weight, the driving mechanism 2 may also be other structures, such as the structure described in the first embodiment.

[0246] On the other hand, Figure 17 As shown, the drive mechanism 2 includes an in-wheel motor 211a, which includes a stator that is mounted on and fixed to an adjustment shaft 31c, and a rotor that is mounted on the stator. The rotor and stator are relatively fixed in the axial direction, and the driving wheel 32a is mounted on and fixed to the rotor. Both ends of the adjustment shaft 31c are fixed to the adjustment bracket 24. In this case, the in-wheel motor 211a, the driving wheel 32a, and the driving shaft 31a (adjustment shaft 31c) are integrated into one body.

[0247] In the second embodiment of the present application, the installation structure and adjustment method of the driven wheel 32b can refer to the first embodiment and will not be repeated here.

[0248] In practical applications, the adjustment method for the driven wheel 32b can also employ the adjustment method provided in the second embodiment of the present application. For example, the driven shaft 31b is an adjustment shaft 31c, with both ends of the adjustment shaft 31c disposed on an adjustment bracket 24. The adjustment bracket 24 is detachably fixedly connected to the chassis assembly 1, and the position of the adjustment bracket 24 on the chassis assembly 1 is adjustable along the axial direction of the adjustment shaft 31c. The specific structure of this adjustment method can be found in the previous section and will not be further described here.
