In particular implementations, the first bracket 130 and the second bracket 140 may be movably coupled in a variety of ways. The following description of the movable connection structure between the first bracket 130 and the second bracket 140 is exemplary with reference to some specific embodiments, but should not be construed as limited to the following structural connection between the first bracket 130 and the second bracket 140.

As shown in fig. 1 and 2, in some embodiments, the first bracket 130 may include one or more first beams 135, the second bracket 140 may be movably connected to the first beams 135, and the second bracket 140 may be capable of moving along the first beams 135 and driving the rotating member 120 and the mounting frame 110 to rotate, so as to adjust a pitch angle of the photovoltaic module 200.

When the first bracket 130 includes a plurality of the first beams 135, the plurality of the first beams 135 may be disposed parallel to each other, and the second bracket 140 may be simultaneously movably connected with the plurality of the first beams 135. In this way, the stress between the first bracket 130 and the second bracket 140 can be balanced, which is beneficial to improving the stability of the connection structure between the first bracket 130 and the second bracket 140.

Alternatively, the first beam 135 may extend along the length direction of the photovoltaic support assembly 100, such that the second bracket 140 can move along the length direction of the photovoltaic support assembly 100 via the first beam 135.

For example, a sliding groove may be disposed along the length direction of the first beam 135, and the second bracket 140 may be provided with a sliding block, and the sliding block may be slidably connected in the sliding groove. For example, a linear guide may be provided on the first beam 135 along a length direction thereof, and the second bracket 140 may be movably connected to the first beam 135 through the linear guide.

It will be appreciated that the second bracket 140 may be movably connected to the first beam 135 by various structures, such as a ball screw or a rack bar, and the movable connection structure between the second bracket 140 and the first beam 135 is not limited herein.

In some embodiments, the second bracket 140 may include a plurality of second beams 142, the second beams 142 may be in one-to-one correspondence with the first beams 135, and the second beams 142 may be movably connected with the corresponding first beams 135. In this manner, a larger connection area may be formed between the first beam 135 and the second beam 142, which may be beneficial for improving stability and robustness between the first beam 135 and the second beam 142.

In some embodiments, a portion of the second beam 142 can extend or retract from the first beam 135. The first cross beam 135 and the second cross beam 142 are sleeved with each other, so that the second cross beam 142 can stably move relative to the first cross beam 135, and the connection firmness between the first bracket 130 and the second bracket 140 can be improved, so that the photovoltaic support assembly 100 can bear a larger weight.

Alternatively, the first cross member 135 may be tubular and extend in a lateral direction. One end of the second beam 142 extends into the first beam 135, and the other end of the second beam 142 extends out of the first beam 135.

Alternatively, the first bracket 130 may include two first beams 135 disposed in parallel, and the second bracket 140 may include two second beams 142 disposed in parallel. In this way, the stress between the first bracket 130 and the second bracket 140 is balanced, so as to improve the stability of the photovoltaic support assembly 100, and the structure is simplified, and the production cost is reduced.

Alternatively, the first cross member 135 may be an integral part of the first bracket body 131, or may be independent of the first bracket body 131. Taking the first bracket body 131 as an example of a frame, the first cross member 135 may be disposed at a top of the frame and extend along a length direction of the frame.

Alternatively, the second beam 142 may be an integral part of the second bracket body 141, or may be independent of the second bracket body 141. For example, the second bracket body 141 may include a connection beam 143 and a plurality of second beams 142 disposed in parallel, one ends of the second beams 142 extend into the first beams 135, the other ends of the second beams 142 extend out of the first beams 135, and the other ends of the plurality of second beams 142 may be connected to the mounting frame 110 through the connection beam 143.

In some embodiments, the second beam 142 is slidably coupled to the first beam 135 via a sliding coupling 150, as shown in fig. 1 and 12. In this way, the frictional resistance between the first beam 135 and the second beam 142 can be reduced, so that the photovoltaic support assembly 100 is easy to be unfolded and folded, which is beneficial to improving the user experience. The sliding connection 150 is described below in connection with a specific example, but it should not be understood that the first and second beams 135 and 142 are limited to being connected by the sliding connection 150 as shown below. In specific implementation, various types of sliding connection structures 150 may be selected according to actual requirements, so long as the sliding connection between the first beam 135 and the second beam 142 can be achieved.

Alternatively, the sliding connection 150 may include a guide rail, a bar-shaped hole 151, a shaft 152, and a roller 153. The guide rail may be disposed outside the first beam 135 and extend in a length direction of the first beam 135. The bar-shaped hole 151 penetrates through a side wall of the first beam 135, and the bar-shaped hole 151 extends along a length direction of the first beam 135. One end of the shaft 152 is connected to the second beam 142, and the other end of the shaft 152 penetrates the bar-shaped hole 151 and extends out of the first beam 135. The roller 153 is connected with the other end of the shaft 152, the rim of the roller 153 is abutted against the guide rail, and the roller 153 can roll along the guide rail. In this way, when the second beam 142 is extended or retracted from the first beam 135, the roller 153 rolls along the guide rail, so that frictional resistance between the first beam 135 and the second beam 142 can be significantly reduced.

Optionally, the sliding connection 150 may include one or more rollers 153. When the sliding connection structure 150 includes a plurality of rollers 153, the plurality of rollers 153 may be sequentially disposed at intervals along the length direction of the first beam 135, the plurality of rollers 153 may be abutted against the guide rail, and each roller 153 may be connected to the second beam 142 through a corresponding shaft 152.

Optionally, the first beam 135 and the second beam 142 may be slidably connected through a plurality of groups of sliding connection structures 150, so as to ensure that the first beam 135 and the second beam 142 are stressed uniformly, thereby improving the motion stability of the second beam 142. For example, the first beam 135 and the second beam 142 may be connected by two sets of sliding connection structures 150, two opposite sides of the first beam 135 are respectively provided with a guide rail and a bar hole 151, two bar holes 151 are respectively provided with a shaft 152 in a penetrating manner, one ends of the two shaft 152 are respectively connected to two opposite sides of the second beam 142, two rollers 153 are respectively connected to the other ends of the shaft 152, and the two rollers 153 are respectively connected to the corresponding guide rails.

Alternatively, the guide rails may include a first guide rail 154 and a second guide rail 155 disposed opposite to each other, the first guide rail 154 being located at the top of the roller 153, and the second guide rail 155 being located at the bottom of the roller 153. In this way, the first guide rail 154 and the second guide rail 155 form a limit on the roller 153 from two opposite sides, so that the roller 153 can stably roll along the transverse direction, and further the second cross beam 142 can stably stretch along the transverse direction.

For example, the first guide rail 154 and the second guide rail 155 may each be formed of a steel bar, the first guide rail 154 may be disposed near an upper edge of the bar-shaped hole 151, and the second guide rail 155 may be disposed near a lower edge of the bar-shaped hole 151. In this way, a rail groove can be formed on the outer side of the first cross member 135, and the roller 153 is disposed in the rail groove.

Alternatively, the roller 153 may be formed by a rolling bearing, an inner ring of the rolling bearing may be fixedly connected to the shaft 152, and an outer ring of the rolling bearing may abut against the guide rail. The rolling bearing is not only easy to obtain, but also has a low friction during rolling, which is beneficial for reducing the friction resistance between the first beam 135 and the second beam 142.

As shown in fig. 13 and 14, in some embodiments, the first beam 135 may be disposed on a top surface of the first bracket body 131, a roller pin row 156 is disposed on the top surface of the first bracket body 131 at a position opposite to the protruding portion of the second beam 142, and a bottom surface of the second beam 142 is in rolling connection with the roller pin row 156. The roller pin row 156 not only can support the extending portion of the second beam 142, avoid the second beam 142 from deflecting by a larger angle, ensure that the second beam 142 stably moves along the transverse direction, but also can avoid the second beam 142 from contacting the first bracket body 131 or reduce the friction resistance between the second beam 142 and the first bracket body 131, so that the second beam 142 can smoothly move along the transverse direction. Alternatively, the needle roller rows 156 may be disposed proximate to the first cross member 135. Alternatively, a plurality of needle roller rows 156 may be provided along the protruding portion of the second beam 142 in the vertical direction in the projection area of the first bracket body 131.

It should be noted that the above structure for realizing the movable connection between the first bracket 130 and the second bracket 140 by the first beam 135 and the second beam 142 is only exemplary, and should not be construed as limiting the movable connection between the first bracket 130 and the second bracket 140 to be realized by the first beam 135 and the second beam 142. In particular embodiments, the first bracket 130 and the second bracket 140 may be movably coupled by a variety of structures. For example, the first bracket 130 and the second bracket 140 may be movably connected by a linear guide, a ball screw, a sliding groove structure, or the like.

In some embodiments, the photovoltaic support assembly 100 further comprises a locking structure for locking the first bracket 130 and the second bracket 140. In this way, after the photovoltaic support assembly 100 is switched to the folded state, the semi-unfolded state or the unfolded state, the locking structure can lock the first bracket 130 and the second bracket 140, so as to avoid that the photovoltaic support assembly 100 is folded or unfolded by itself under an uncontrolled condition. For example, the photovoltaic support assembly 100 may be adjusted to a folded state before transportation, and the first and second brackets 130 and 140 may be locked by the locking structure, so that the photovoltaic support assembly 100 may be maintained in the folded state during transportation. Also for example, when the photovoltaic support assembly 100 is deployed, the photovoltaic support assembly 100 may be unfolded according to the local sunlight irradiation angle, and then the first bracket 130 and the second bracket 140 are locked by the locking structure, so that the photovoltaic assembly 200 maintains an optimal pitching angle, so as to improve the power generation efficiency of the photovoltaic assembly 200.

In particular implementations, the photovoltaic support assembly 100 can employ various types of locking structures capable of locking the first bracket 130 and the second bracket 140. The locking arrangement is described below in connection with several specific embodiments, but it should not be understood that the locking arrangement is limited to the arrangement shown below.

As shown in fig. 13 and 14, in some embodiments, the locking structure may include a latch 161, and a sidewall of the first beam 135 is provided with a first locking hole 162 therethrough. One or more second lock holes 163 are provided at positions of the second cross beam 142 corresponding to the first lock holes 162, and when a plurality of second lock holes 163 are provided on the second cross beam 142, the plurality of second lock holes 163 are sequentially spaced apart in the transverse direction. The latch lock 161 is disposed outside the first beam 135 and opposite to the first locking hole 162, and the latch lock 161 is configured to penetrate the first locking hole 162 and the second locking hole 163 to lock the first beam 135 and the second beam 142. For example, a plurality of second locking holes 163 may be provided at equal intervals along the moving direction of the second beam 142. When the pitch angle of the photovoltaic module 200 is adjusted to be close to the target pitch angle and one second lock hole 163 is opposite to the first lock hole 162, the latch lock 161 can be controlled to be inserted into the first lock hole 162 and the second lock hole 163, so as to achieve the purpose of locking the first beam 135 and the second beam 142. The locking structure is simple in structure and has a good locking effect.

With continued reference to fig. 13 and 14, in some embodiments, the latch 161 may include a keyway 1611, a locking pin 1613, a spring 1614, a first stop 1615, and a second stop 1616. The pin receptacle 1611 may be fixedly coupled to the first cross member 135. It will be appreciated that the keyway 1611 is disposed adjacent to the first locking aperture 162. When the first locking hole 162 is formed on the side surface of the first beam 135 and penetrates through the side wall of the first beam 135 along the beam, the pin seat 1611 may be disposed on the outer side wall of the first beam 135. When the first locking hole 162 is formed on the top surface of the first cross member 135 and vertically penetrates through the top wall of the first cross member 135, the pin seat 1611 may be disposed on the top surface of the first cross member 135.

The locking pin 1613 is movably and rotatably disposed on the keyway 1611, with one end of the locking pin 1613 opposite the first locking aperture 162. Alternatively, the axis extending line of the lock pin 1613 may be disposed through the first lock hole 162, and the lock pin 1613 may be configured to be movable in the direction of its own axis and rotatable about its own axis.

Optionally, the pin base 1611 may be provided with a pin hole 1612 opposite to the first lock hole 162, an axis extending line of the pin hole 1612 may penetrate the first lock hole 162, and the lock pin 1613 may penetrate the pin hole 1612 and be configured to move and rotate under the limit of the pin hole 1612.

Alternatively, the pin base 1611 may have two support plates with opposite plate surfaces, where the plate surfaces of the two support plates are opposite to the first lock hole 162, one of the two support plates is relatively close to the first lock hole 162, and the other of the two support plates is relatively far from the first lock hole 162. The two support plates are provided with pin holes 1612 opposite to the first lock hole 162, and the two pin holes 1612 may be penetrated by the lock pin 1613.

The first stop 1615 is disposed on the keyway 1611 at a location near the locking pin 1613. Alternatively, the first stopper 1615 may be disposed between two of the support plates. Alternatively, the latch lock 161 may include two first stops 1615, and two first stops 1615 may be disposed on opposite sides of the latch 1613. Optionally, the first stop block 1615 may be cylindrical, and a groove for clamping the second stop block 1616 may be disposed on the first stop block 1615.

The second stopper 1616 is provided on the outer circumferential surface of the lock pin 1613. Alternatively, the second stop 1616 may be cylindrical, and the second stop 1616 may extend along a radius of the lock pin 1613.

The two ends of the spring 1614 are respectively abutted against the lock pin 1613 and the pin seat 1611, and the spring 1614 is configured to apply an elastic force to the lock pin 1613 so that the lock pin 1613 has a tendency to move in a direction extending into the first lock hole 162. Alternatively, the spring 1614 may be a coil spring 1614, and the spring 1614 may be sleeved on the latch 1613. One end of the spring 1614 may abut against a support plate relatively far from the first lock hole 162 of the two support plates, the other end of the spring 1614 may abut against the second stop block 1616, and the spring 1614 may be configured to be in a compressed state. In this manner, the spring 1614 can apply a spring force to the latch 1613 in a direction extending into the first latch aperture 162, such that the latch 1613 has a tendency to move in a direction extending into the first latch aperture 162, and the spring 1614 can also limit the release of the latch 1613 from the keyway 1611.

When the first beam 135 and the second beam 142 need to be locked, the lock pin 1613 may be rotated to enable the second stop block 1616 to avoid the first stop block 1615, and the lock pin 1613 may be automatically inserted into the first lock hole 162 and the second lock hole 163 under the action of elastic force, and may be kept inserted into the first lock hole 162 and the second lock hole 163 under the action of elastic force, so as to maintain a locked state. When unlocking is desired, the latch 1613 may be pulled out in the opposite direction until the second stop 1616 is positioned on the side of the first stop 1615 remote from the first latch aperture 162. The lock pin 1613 is rotated, so that at least part of the second stop block 1616 is opposite to the first stop block 1615, and the lock pin 1613 is released, and the second stop block 1616 can abut against the first stop block 1615 under the action of elastic force, so as to limit the lock pin 1613 to move towards the direction extending into the first lock hole 162, so as to maintain the unlock state.

The latch lock 161 is not limited to the above-described structure. For example, the latch 161 may include only a keyway 1611, a locking pin 1613, and a spring 1614.

In some embodiments, the locking structure includes a fastening bolt 164, as shown in fig. 13. The side wall of the first cross beam 135 is provided with a through hole (not shown in the figure), the fastening bolt 164 is in threaded connection with the first cross beam 135, one end of the fastening bolt 164 extends into the first cross beam 135 via the through hole, and one end of the fastening bolt 164 can abut against the second cross beam 142 to lock the first cross beam 135 and the second cross beam 142. The first cross beam 135 and the second cross beam 142 are locked through the fastening bolts 164, so that the structure is simple, the implementation is easy, the first cross beam 135 and the second cross beam 142 can be locked at any position, and the pitch angle of the photovoltaic module 200 can be accurately regulated. Alternatively, the through hole may be a threaded hole, and the fastening bolt 164 may be screwed with the threaded hole. Alternatively, a fastening nut 165 may be disposed on the first beam 135, a threaded hole of the fastening nut 165 may be opposite to the through hole, and the fastening bolt 164 may be screwed with the fastening nut 165 and pass through the through hole.

In some embodiments, the locking structure may include a first security aperture (not shown), a second security aperture (not shown), a security nut 166, and a security bolt 167, as shown in fig. 15. The first safety hole extends through the first cross member 135. The safety nut 166 is fixedly connected with the first cross beam 135, and a screw hole of the safety nut 166 is opposite to the first safety hole. The second safety vent extends through the second beam 142 and is configured to oppose the first safety vent when the second beam 142 is moved to a first target position relative to the first beam 135. The safety bolt 167 is used to pass through the first safety hole and the second safety hole, and is in threaded connection with the safety bolt 167 to lock the first beam 135 and the second beam 142. The locking structure has a good locking effect, is simple in structure and is easy to realize. Alternatively, the first target position may be a relative position of the second beam 142 and the first beam 135 when the photovoltaic support assembly 100 is in a folded state, an unfolded state, or other posture. For example, when the photovoltaic support assembly 100 is switched to the folded state, the first safety hole and the second safety hole are opposite, and the first beam 135 and the second beam 142 are locked by the safety bolt 167, so that uncontrolled unfolding of the photovoltaic support assembly 100 during transportation can be avoided.

It should be noted that, in the implementation, one of the locking structures described above may be disposed on the photovoltaic support assembly 100, or a plurality of locking structures may be disposed on the photovoltaic support assembly 100 at the same time. For example, the latch lock 161, the fastening bolt 164 and the safety bolt 167 may be simultaneously provided on the photovoltaic support module 100, locking of a fixed step length is achieved by the latch lock 161, locking of an arbitrary relative position is achieved by the fastening bolt 164, and locking of a folded state or an unfolded state is achieved by the safety bolt 167.

In some embodiments, the photovoltaic support assembly 100 further includes a limiting structure for limiting the relative position of the first bracket 130 and the second bracket 140. By providing a limiting structure, the first bracket 130 and the second bracket 140 can be ensured to move within a target relative position range, so that the second beam 142 is prevented from completely falling out of the first beam 135 or excessively shrinking into the first beam 135.

The limit structure is described below in connection with several embodiments, but should not be construed as limited to the structures shown below.

In some embodiments, the stop structure may include a first stop member 171, as shown in fig. 13. The first limiting member 171 is disposed on the outer side of the second beam 142, and the first limiting member 171 is configured to abut against an end surface of the first beam 135 when the second beam 142 is retracted to the second target position, so as to limit the second beam 142 from continuously retracting into the first beam 135. The second target position may be a relative position of the second beam 142 and the first beam 135 when the photovoltaic support assembly 100 is in the folded state. In this way, excessive retraction of the second beam 142 into the first beam 135 can be avoided. Alternatively, the first limiting member 171 may include a limiting block, which may be fixed to the outer side surface of the second beam 142 by, for example, a bolt.

In some embodiments, the stop feature may include a second stop feature 172, as shown in fig. 16. The second limiting member 172 is disposed on the first bracket 130 and located within a rotation radius of the rotating member 120, and the second limiting member 172 is configured to stop against the rotating member 120 when the second beam 142 extends to a third target position, so as to limit the rotating member 120 from continuing to rotate and limit the second beam 142 from continuing to extend. The third target position may be a relative position of the second beam 142 and the first beam 135 when the photovoltaic support assembly 100 is in the deployed state. In this way, the second beam 142 can be prevented from protruding excessively from the first beam 135.

Optionally, two connection plates 133 with plate surfaces spreading vertically may be disposed at a position on the support base 132 near the top end, and the two connection plates 133 may be disposed opposite to each other with a connection space reserved therebetween. The other end of the rotating member 120 may extend into the connection space, and the rotating member 120 may be rotatably connected to the two connection plates 133 through a pin or a rotation shaft. The second limiting member 172 may include a limiting rod connected between the two connection plates 133 and located within a radius of rotation of the rotating member 120. For example, the limit rod may be disposed above the rotating member 120 and near the other end of the rotating member 120, and during the process that the second beam 142 extends out from the first beam 135, the pitch angle of the rotating member 120 is gradually reduced, and the other end of the rotating member 120 is gradually lifted until the photovoltaic support assembly 100 is switched to the unfolded state, the rotating member 120 abuts against the limit rod, and the limit rod limits the rotating member 120 from continuing to rotate.

It should be noted that, only one of the first limiting member 171 and the second limiting member 172 may be provided on the photovoltaic support assembly 100, and the first limiting member 171 and the second limiting member 172 may be provided at the same time. That is, the limiting structure includes a first limiting member 171 and/or a second limiting member 172.

In some embodiments, the photovoltaic support assembly 100 further comprises a driving device for driving the second bracket 140 to move. As such, it is beneficial to improve the degree of automation and the state switching efficiency of the photovoltaic support assembly 100. Alternatively, the driving means may include a winch 180, and a rope 181 of the winch 180 is connected to the second bracket 140, as shown in fig. 1 and 7.

For example, the first bracket body 131 may be a frame, a front end of the frame may be provided with a beam, and the second bracket body 141 may be connected at a rear end of the frame. The winch 180 may be disposed on the beam, and the rope 181 of the winch 180 may be connected to the middle portion of the connection beam 143 of the second bracket body 141.

During deployment, the locking structure may be switched from the locked state to the unlocked state. The caster assembly 144 is lowered such that the caster assembly 144 contacts the ground. Then, the rotatable winch 180 releases the rope 181, and the second bracket 140 moves toward the tail direction under the gravity action of the photovoltaic module 200 and the mounting frame 110, and the pitch angle of the photovoltaic module 200 is gradually reduced. Until the pitch angle of the photovoltaic module 200 reaches the target pitch angle, the rotation of the winch 180 may be stopped, and the locking structure may be switched from the unlocking state to the locking state, as shown in fig. 5, or as shown in fig. 6 and 7.

During folding, the locking structure may be switched from the locked state to the unlocked state. Then, the winch 180 is rotated to wind the rope 181, the second bracket 140 is pulled to move toward the direction of the vehicle head, the length of the rope 181 in the transverse direction of the photovoltaic module 200 is gradually reduced, and the pitching angle of the photovoltaic module 200 is gradually increased. Until the photovoltaic module 200 is switched to the folded state, the rotation of the winch 180 may be stopped, the locking mechanism may be switched from the unlocked state to the locked state, and the caster assembly 144 may be lifted to disengage the caster assembly 144 from the ground, as shown in fig. 3 and 4.

It will be appreciated that the driving means is not limited to the capstan 180, but may be a hydraulic rod, a pneumatic rod, a servo rod, or a motor, etc. to drive the second bracket 140 to move.

In some embodiments, as shown in fig. 1, the rotating member 120 may include a first rod 121 and a second rod 122, where the first rod 121 is rotatably connected to the mounting bracket 110, and the first rod 121 extends along a rotation center line direction of the first rod 121 and the mounting bracket 110, and one end of the second rod 122 is fixedly connected to a middle portion of the second rod 122, and the other end of the second rod 122 is rotatably connected to the first bracket 130. In this way, the rotation member 120 is approximately T-shaped as a whole, and can stably support the mounting frame 110 and the photovoltaic module 200 mounted on the mounting frame 110. Alternatively, the first rod 121 may be connected to the mounting rack 110 through a plurality of hinge structures, and the plurality of hinge structures may be sequentially spaced along the length direction of the first rod 121. Alternatively, the other end of the second rod 122 may extend into the connection space of the supporting seat 132, and may be rotatably connected to two connection plates 133 by, for example, a pin, as shown in fig. 16.

Embodiments of the present application also provide a photovoltaic light truck, as shown in fig. 3 to 7, which may include a light assembly 300, a photovoltaic assembly 200, and a photovoltaic support assembly 100 as described in any of the embodiments above. The photovoltaic module 200 is mounted on the mounting frame 110 of the photovoltaic support module 100. The first bracket 130 includes a first bracket body 131 and a wheel assembly 134, and the wheel assembly 134 is supported at the bottom of the first bracket body 131. The lamp assembly 300 is disposed on the first bracket body 131 and/or the second bracket 140 of the photovoltaic support assembly 100. Alternatively, the lamp assembly 300 may include a lamp post supported at a front end of the first bracket 130 by a support base 132, and electrical equipment arranged on top of the first bracket 130.

Because the photovoltaic support assembly 100 has the folded state and the unfolded state, the occupied area is smaller in the folded state, which is beneficial to reducing the transportation cost. During deployment, the length of the photovoltaic support assembly 100 in the lateral direction can be increased. Even if the size of the supported photovoltaic module 200 is large, a stable supporting effect can be formed for the photovoltaic module 200. Moreover, the pitching angle of the photovoltaic module 200 can be adjusted in the unfolding process, so that the power generation efficiency of the photovoltaic module 200 is improved, and an adjusting mechanism special for adjusting the pitching angle of the photovoltaic module 200 is omitted. Therefore, the photovoltaic lamp car applying the photovoltaic support assembly 100 has simple structure and lower transportation cost, and has higher stability even if the photovoltaic assembly 200 with a large size is arranged.
