In addition, features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, unless otherwise specified, "multiple" means two or more.

[0032] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0033] like Figure 1 As shown, the utility model provides a battery pack entry device, including an entry vehicle 100 and a movable lifting mechanism 200. The movable lifting mechanism 200 is used to carry the entry vehicle 100 and can drive the entry vehicle 100 to rise and fall.

[0034] like Figure 2 As shown, the cabin entry vehicle 100 includes a base frame 110 , a roller assembly 120 , a pushing mechanism 130 and a front stop assembly 150 .

[0035] The base frame 110 is the main bearing mechanism.

[0036] The roller assembly 120 is disposed on the base frame 110 , and the roller assembly 120 is used to carry the battery pack.

[0037] Specifically, the roller assembly 120 serves to carry the battery pack, and the roller assembly 120 can also guide the battery pack. The friction force to which the battery pack is subjected when moving on the roller assembly 120 is small, which can improve the problem of battery pack wear.

[0038] It is understandable that, in the absence of the roller assembly 120, the battery pack is carried by the base frame 110. When the battery pack moves relative to the base frame 110, there is sliding friction between the battery pack and the base frame 110, and the friction between the two is relatively large, which can easily cause wear of the battery pack. However, by providing the roller assembly 120 on the base frame 110 and using the roller assembly 120 to carry the battery pack, when the battery pack moves relative to the base frame 110, there is rolling friction between the battery pack and the roller assembly 120, and the friction between the two is relatively small, which can improve the problem of battery pack wear.

[0039] The pushing mechanism 130 is disposed on the base frame 110 , and is used to push the battery pack.

[0040] It can be understood that, under the push of the pushing mechanism 130 and under the guidance of the roller assembly 120 , the battery pack moves along the first direction.

[0041] Combination Figure 2 and Figure 3Specifically, the pushing mechanism 130 includes a driving component (not shown) and a pushing component 132 drivingly connected to the driving component, the driving component is used to drive the pushing component 132 to move along a first direction or a second direction opposite to the first direction, wherein when the driving component drives the pushing component 132 to move along the first direction, the pushing component 132 can push the battery pack to move along the first direction.

[0042] It can be understood that the driving assembly is disposed on the base frame 110, and the driving assembly can drive the pushing assembly 132 to move in the first direction or the second direction. After the battery pack is placed on the roller assembly 120, the battery pack is located on the moving path of the pushing assembly 132 moving in the first direction, that is, when the driving assembly drives the pushing assembly 132 to move in the first direction, the pushing assembly 132 will push the battery pack to move in the first direction. When the driving assembly drives the pushing assembly 132 to move in the second direction, the pushing assembly 132 can be reset.

[0043] Furthermore, the driving assembly includes a motor and a chain 131 driven by the motor, wherein the chain 131 can be wound around a sprocket, and the motor drives the sprocket to rotate, thereby driving the chain 131 to run. The pushing assembly 132 is fixedly connected to the chain 131, and under the action of the motor, the chain 131 can run forward or reverse, thereby driving the pushing assembly 132 to move along the first direction or the second direction.

[0044] Combination Figure 3 and Figure 4 Furthermore, the pushing assembly 132 includes a bottom plate 1321 and a pushing member 1322 disposed on the bottom plate 1321 , and the bottom plate 1321 is fixedly connected to the chain 131 .

[0045] like Figure 2 As shown, it should be noted that the roller assembly 120 includes two groups of rollers 121, and the two groups of rollers 121 are arranged at intervals along a third direction perpendicular to the first direction, and each group of rollers 121 includes a plurality of rollers 121 spaced and arranged in parallel along the first direction.

[0046] It can be understood that each roller 121 is rotatably connected to the base frame 110, that is, the roller 121 can rotate relative to the base frame 110 around the axis of the roller 121, and the axis of the roller 121 is parallel to the third direction. The battery pack is carried on the two groups of rollers 121. When the battery pack is pushed by the pushing mechanism 130 and moves along the first direction, the battery pack drives the roller 121 to roll. Conversely, when the roller 121 rolls, it guides the battery pack to move along the first direction.

[0047] Combination Figure 5 and Figure 6The front block assembly 150 is movably connected to the base frame 110, that is, the front block assembly 150 can switch positions, and the front block assembly 150 has a blocking position and an avoidance position. When the front block assembly 150 is in the blocking position, the front block assembly 150 can block the battery pack from moving along the first direction. When the front block assembly 150 is in the avoidance position, the front block assembly 150 avoids the battery pack and does not hinder the pushing assembly 132 from pushing the battery pack to move along the first direction.

[0048] It can be understood that after the battery pack is placed on the roller assembly 120, and while the movable lifting mechanism 200 drives the cabin transport vehicle 100 to move or lift, the front block assembly 150 can be switched to a blocking position. At this time, the front block assembly 150 can block the battery pack from moving in the first direction, thereby reducing the risk of the battery pack falling off the cabin transport vehicle 100; when the battery pack needs to be pushed into the energy storage battery compartment, the front block assembly 150 can be switched to an avoidance position. At this time, the front block assembly 150 can avoid the battery pack, making it easier for the battery pack to move in the first direction under the push of the pushing mechanism 130 and be pushed into the energy storage battery compartment.

[0049] When the battery pack loading device of the utility model is used, first, the battery pack is placed on the roller assembly 120, and then the movable lifting mechanism 200 drives the loading vehicle 100 to align the battery pack with the installation layer corresponding to the energy storage battery compartment, and then the driving assembly drives the pushing assembly 132 to move along the first direction, so as to push the battery pack into the installation layer corresponding to the energy storage battery compartment. Among them, the roller assembly 120 plays the role of carrying the battery pack, and the roller assembly 120 can also guide the battery pack. The friction force on the battery pack when moving on the roller assembly 120 is small, which can improve the problem of battery pack being worn. In addition, after the battery pack is placed on the roller assembly 120 and in the process of being moved into the cabin vehicle 100, the front block assembly 150 can be switched to a blocking position. At this time, the front block assembly 150 can block the battery pack from moving in the first direction, thereby reducing the risk of the battery pack falling off the cabin transport vehicle 100; when the battery pack needs to be pushed into the energy storage battery compartment, the front block assembly 150 can be switched to an avoidance position. At this time, the front block assembly 150 can avoid the battery pack, making it easier for the battery pack to move in the first direction under the push of the pushing mechanism 130 and be pushed into the energy storage battery compartment.

[0050] like Figure 6 As shown, in some embodiments, the front stopper assembly 150 includes a hinge seat 151 disposed on the base frame 110, and a front stopper 152 rotatably connected to the hinge seat 151, and the front stopper 152 can rotate in a plane perpendicular to the first direction.

[0051] It can be understood that the hinge seat 151 is fixed to the upper surface of the base frame 110, and the hinge seat 151 is used to install the front stop block 152 and enable the front stop block 152 to rotate relative to the base frame 110. When the front stop assembly 150 is in the blocking position, the front stop block 152 is in a horizontal state. At this time, the front stop block 152 can prevent the battery pack from moving along the first direction and falling. When the front stop assembly 150 is in the avoidance position, the front stop block 152 is in a vertical state to avoid the battery pack.

[0052] Specifically, there are two front block assemblies 150, which are respectively arranged on both sides of the base frame 110 along the third direction. When the two front block assemblies 150 are in the blocking position at the same time, the two front block assemblies 150 can limit the battery pack at the same time, so that the battery pack is more stably stressed.

[0053] Combination Figure 3 and Figure 4 In some embodiments, the cabin entry vehicle 100 further includes an auxiliary push rod 140 , one end of which is detachably connected to the pushing assembly 132 , and the auxiliary push rod 140 extends from the pushing assembly 132 along a first direction.

[0054] It is understandable that when the battery pack entry device of the utility model is used, first, the battery pack is placed on the roller assembly 120, and the movable lifting mechanism 200 drives the entry vehicle 100 to move and lift, so that the battery pack is aligned with the installation layer corresponding to the energy storage battery compartment. Then, the driving assembly drives the pushing assembly 132 to move along the first direction, thereby pushing the battery pack to move along the first direction. After the pushing assembly 132 moves a certain distance along the first direction, the driving assembly drives the pushing assembly 132 to move along the second direction, and then the auxiliary push rod 140 is installed on the pushing assembly 132. After that, the driving assembly drives the pushing assembly 132 and the auxiliary push rod 140 to move together along the first direction, and the battery pack is pushed into the energy storage battery compartment. The function of the auxiliary push rod 140 is to increase the pushing stroke of the battery pack and ensure that the battery pack is installed in place. After the battery pack is pushed into the energy storage battery compartment, the auxiliary push rod 140 needs to be removed, and the pushing assembly 132 needs to be driven to move along the second direction to reset.

[0055] Furthermore, a plurality of abutment blocks 141 are provided at one end of the auxiliary push rod 140 away from the pushing assembly 132. The plurality of abutment blocks 141 are arranged at intervals along the third direction. The plurality of abutment blocks 141 are used to jointly abut the battery pack. In this way, the pressure on the battery pack can be more uniform, thereby improving the problem of damage to the battery pack due to excessive local pressure.

[0056] In some embodiments, the pushing component 132 is provided with a first assembly hole, and one end of the auxiliary push rod 140 is provided with a second assembly hole corresponding to the first assembly hole. A fastener is passed through the first assembly hole and the second assembly hole to make the auxiliary push rod 140 detachably connected to the pushing component 132.

[0057] Specifically, the fastener is a screw, one of the first assembly hole and the second assembly hole is a screw hole, and the other is a through hole.

[0058] like Figure 2 As shown, in some embodiments, guide blocks 160 are further provided on both sides of the base frame 110 arranged along the third direction. The guide blocks 160 are used to guide the battery pack and prevent the battery pack from falling from the side of the base frame 110 .

[0059] like Figure 5 and Figure 6 As shown, in some embodiments, the cabin vehicle 100 further includes a fine-tuning assembly 170, which is disposed on the base frame 110. There are two fine-tuning assemblies 170, which are spaced apart along a third direction, and the two fine-tuning assemblies 170 can be close to or away from each other.

[0060] It is understandable that the fine-tuning assembly 170 can fine-tune the left and right positions of the battery pack, thereby ensuring that there is no large deviation in the angle of the battery pack after it enters the energy storage battery compartment.

[0061] Specifically, the fine-tuning assembly 170 includes a mounting plate 171 disposed on the base frame 110, an adjustment plate 172 disposed on the inner side of the mounting plate 171, and an adjustment member 173 passing through the mounting plate 171 and connected to the adjustment plate 172. The adjustment member 173 can be operably driven to drive the adjustment plate 172 to move along a third direction or a fourth direction opposite to the third direction.

[0062] Specifically, the mounting plate 171 is provided with a screw hole, and the adjusting member 173 is provided with a threaded section. The threaded section is passed through the screw hole and is connected to the adjusting member 173, and the threaded section is rotatable relative to the adjusting member 173. By rotating the adjusting member 173, the adjusting plate 172 can be driven to move along the third direction or the fourth direction opposite to the third direction, thereby correcting the battery pack.

[0063] Furthermore, the adjusting member 173 is also connected to a hand wheel 174 for user convenience.

[0064] like Figure 7 As shown, the movable lifting mechanism 200 includes a base assembly 210, a stand assembly 220, a bracket assembly 230 and a lifting drive assembly 240.

[0065] The base assembly 210 is provided with rollers 211 . The base assembly 210 is the main bearing mechanism, and the entire movable lifting mechanism 200 can be moved by means of the rollers 211 .

[0066] The stand assembly 220 is disposed on the base assembly 210 , and the stand assembly 220 is used to guide the lifting and lowering of the bracket assembly 230 , wherein the bracket assembly 230 is used to carry the vehicle 100 into the cabin.

[0067] The lifting drive assembly 240 is used to drive the bracket assembly 230 to rise and fall, thereby driving the cabin vehicle 100 and the battery pack to rise and fall.

[0068] In some embodiments, the lifting drive assembly 240 is an electric screw. In other embodiments, the lifting drive assembly 240 can be in the form of a motor and a chain. The motor has a built-in brake function and can be stopped and positioned at any time.

[0069] like Figure 7 As shown, it can be understood that when the battery pack loading device of the utility model is in use, first, the battery pack is placed on the loading vehicle 100, and then the loading vehicle 100 is driven to move and lift by the movable lifting mechanism 200, so that the battery pack is aligned with the installation layer corresponding to the energy storage battery compartment, and then the loading vehicle 100 pushes the battery pack into the energy storage battery compartment.

[0070] like Figure 7 , Fig. 9 As shown, further, the bracket assembly 230 includes two brackets 231 arranged at intervals in the horizontal direction, and the two brackets 231 jointly support the cabin vehicle 100.

[0071] It should be noted that the lifting drive assembly 240 can simultaneously drive the two brackets 231 to lift, and the two brackets 231 can also be synchronously driven to lift by the two lifting drive assemblies 240. The lifting drive assembly 240 can be an electric screw structure or other driving devices.

[0072] Combination Figure 7 and Figure 8 Further, the bracket 231 has two guide rollers 2311 arranged at intervals in the horizontal direction, and the frame assembly 220 has a guide column 221, and the two guide rollers 2311 respectively roll with the two sides of the guide column 221. In this way, the stability of the bracket 231 during the lifting process can be improved.

[0073] When the battery pack loading device of the utility model is used, first, the battery pack is placed on the roller assembly 120, and then the movable lifting mechanism 200 drives the loading vehicle 100 to lift and lower, so that the battery pack is aligned with the installation layer corresponding to the energy storage battery compartment, and then the driving assembly drives the pushing assembly 132 to move along the first direction, so as to push the battery pack into the installation layer corresponding to the energy storage battery compartment. Among them, the roller assembly 120 plays the role of carrying the battery pack, and the roller assembly 120 can also guide the battery pack. The friction force on the battery pack when moving on the roller assembly 120 is small, which can improve the problem of battery pack wear. It is understandable that, in the absence of the roller assembly 120, the battery pack is carried by the base frame 110. When the battery pack moves relative to the base frame 110, there is sliding friction between the battery pack and the base frame 110, and the friction between the two is relatively large, which can easily cause wear of the battery pack. However, by providing the roller assembly 120 on the base frame 110 and using the roller assembly 120 to carry the battery pack, when the battery pack moves relative to the base frame 110, there is rolling friction between the battery pack and the roller assembly 120, and the friction between the two is relatively small, which can improve the problem of battery pack wear. In addition, after the battery pack is placed on the roller assembly 120 and in the process of being moved into the cabin vehicle 100, the front block assembly 150 can be switched to a blocking position. At this time, the front block assembly 150 can block the battery pack from moving in the first direction, thereby reducing the risk of the battery pack falling off the cabin transport vehicle 100; when the battery pack needs to be pushed into the energy storage battery compartment, the front block assembly 150 can be switched to an avoidance position. At this time, the front block assembly 150 can avoid the battery pack, making it easier for the battery pack to move in the first direction under the push of the pushing mechanism 130 and be pushed into the energy storage battery compartment.
