Description

Technical Field

[0001] This invention relates to the field of heavy-duty truck battery swapping technology, and in particular to a heavy-duty truck battery swapping device and method for use in limited spaces within existing buildings. Background Technology

[0002] With the popularization of new energy heavy-duty trucks, heavy-duty truck battery swapping technology, as a key solution to address range anxiety, has been widely used in logistics parks, ports, and other scenarios. Currently, mainstream heavy-duty truck battery swapping equipment in the industry is deployed in the form of newly built independent buildings in outdoor sites. Under this deployment mode, the design of battery swapping equipment does not need to consider external space limitations and can be developed and manufactured according to standardized dimensions. For example, the gantry height, lateral span of the traversing mechanism, and length of the transporter guide rail of standard battery swapping equipment can all be set according to the need to maximize battery swapping efficiency, without the need to adapt to the spatial constraints of existing buildings. The installation and commissioning process only needs to match the preset parameters of the new building, making the overall implementation relatively easy.

[0003] However, in scenarios such as urban core logistics hubs and former industrial parks, due to factors such as scarce land resources, complex approval processes for new buildings, and controllable renovation costs, the market has gradually generated actual demand for equipping heavy trucks with battery swapping equipment based on existing buildings (such as original factories, existing warehouse buildings, indoor parking lots, etc.). However, the design of existing standard heavy-duty truck battery swapping equipment is not adapted to the spatial characteristics of existing buildings. There is a significant contradiction between its core structural dimensions and the interior space of existing buildings: on the one hand, the interior net height of existing buildings is usually lower than that of newly built dedicated battery swapping buildings, which means that components with large vertical dimensions, such as gantry frames and lifting drive mechanisms, in standard battery swapping equipment cannot meet the installation height requirements; on the other hand, the floor plan of existing buildings is fixed, and the available horizontal and vertical space inside is limited. The length of the guide rails of the standard battery swapping equipment and the lateral movement span of the horizontal lifting transport vehicle often exceed the floor plan size limitations of existing buildings. This directly results in the inability to install standard battery swapping equipment inside existing buildings. Even if forced to modify the space, the battery swapping action will be stuck due to space compression, the stability of equipment operation will decrease, and even the normal battery swapping function may not be realized. This seriously restricts the promotion and application of heavy-duty truck battery swapping equipment in existing building scenarios.

[0004] Therefore, existing battery swapping equipment has the problem of being difficult to adapt to existing buildings and being unable to be installed due to limitations in indoor height and floor plan dimensions. Summary of the Invention

[0005] The purpose of this invention is to provide a heavy-duty truck battery swapping device and method for use in the limited space of existing buildings, aiming to solve the problem that existing battery swapping devices are difficult to adapt to existing buildings and cannot be installed due to limitations in indoor height and floor plan dimensions.

[0006] In a first aspect, the present invention provides a heavy-duty truck battery swapping device for use in confined spaces within existing buildings, the heavy-duty truck battery swapping device comprising: The guide rail accessory includes a guide support frame and a transporter guide rail, wherein the transporter guide rail is disposed below the guide support frame; A gantry frame is disposed above and connected to the guide support frame to adjust its longitudinal position along the guide support frame. A transverse lifting transport vehicle is connected to the gantry frame and moves laterally along the gantry frame. The transverse lifting transport vehicle is equipped with a lifting drive mechanism. A battery gripping platform is located below the horizontal lifting transport vehicle and is lifted and lowered under the drive of the lifting drive mechanism to perform battery gripping and releasing actions. A transverse transporter is connected to the transporter guide rail and moves longitudinally along the transporter guide rail.

[0007] Furthermore, a camera is installed on the gantry frame, which is used to acquire the alignment reference information of the heavy truck to be swapped.

[0008] Furthermore, the battery gripping platform is equipped with a laser sensor, which is used to detect the tilt angle information between the new battery and the heavy truck battery compartment.

[0009] Furthermore, the lifting drive mechanism includes a lifting motor and a drum, the drum rotating under the drive of the lifting motor; A movable pulley is fixedly installed below the battery gripping platform, and the drum is connected to the movable pulley via a flexible transmission component.

[0010] Furthermore, both sides of the battery gripping platform are equipped with electric push rods and hooks that are connected to the electric push rods in a transmission manner. The hooks rotate under the drive of the electric push rods.

[0011] Furthermore, a protective guardrail is provided below the guide support frame, and the protective guardrail is provided on one side of the transporter guide rail along the extension direction of the transporter guide rail.

[0012] Furthermore, a protective fence is provided on the outside of the transporter guide rail.

[0013] Furthermore, the transverse transporter is provided with a guide assembly.

[0014] Furthermore, a servo cylinder is provided on the gantry frame, and the gantry frame is adjusted longitudinally along the guide support frame under the drive of the servo cylinder; The lateral lifting transport vehicle is equipped with a first lateral motor, and the lateral lifting transport vehicle moves laterally along the gantry under the drive of the first lateral motor; The transverse transporter is equipped with a second transverse motor, and the transverse transporter moves longitudinally along the transporter guide rail under the drive of the second transverse motor.

[0015] Secondly, the present invention also provides a method for battery swapping of heavy-duty trucks within a limited space of an existing building, applied to the battery swapping equipment for heavy-duty trucks within a limited space of an existing building as described in the first aspect above, the method comprising: Once the heavy truck to be swapped enters the swapping area and stops at the work position, the gantry is longitudinally adjusted along the guide support frame according to the alignment reference information obtained by the camera to form a longitudinal fit with the heavy truck's battery compartment. The transverse lifting transport vehicle moves laterally along the gantry and moves to directly above the heavy truck's battery compartment. The lifting drive mechanism drives the battery gripping platform to descend to the battery gripping position, grips the heavy truck's primary battery, and then rises. The lateral lifting transport vehicle moves laterally to a position above the lateral transporter. The lifting drive mechanism drives the battery gripping platform to descend, releasing the heavy truck's primary battery onto the lateral transporter. The lateral transporter moves longitudinally along the transporter guide rail, transferring the heavy truck's primary battery to a preset storage position. The lateral transporter moves the new battery longitudinally to below the battery gripping platform. The lifting drive mechanism drives the battery gripping platform to descend, grip the new battery, and then rise. The lateral lifting transport vehicle moves laterally to above the heavy truck battery compartment. The lifting drive mechanism drives the battery gripping platform to descend, sending the new battery into the heavy truck battery compartment. The battery gripping platform releases the new battery and then resets. The lateral lifting transport vehicle resets along the gantry, and the gantry resets along the guide support frame. The battery swapping heavy truck leaves the battery swapping area, and the battery swapping process ends.

[0016] This invention discloses a heavy-duty truck battery swapping device and method for use in limited spaces within existing buildings. The heavy-duty truck battery swapping device includes: a guide rail accessory comprising a guide support frame and a transporter guide rail, the transporter guide rail being disposed below the guide support frame; a gantry frame disposed above and connected to the guide support frame for longitudinal position adjustment along the guide support frame; a lateral lifting transport vehicle connected to the gantry frame for lateral movement along the gantry frame, the lateral lifting transport vehicle being equipped with a lifting drive mechanism; a battery gripping platform disposed below the lateral lifting transport vehicle and lifted under the drive of the lifting drive mechanism for performing battery gripping and releasing actions; and a lateral transporter connected to the transporter guide rail for longitudinal movement along the transporter guide rail. This invention addresses the constraints of limited space in existing buildings by optimizing the equipment's structural layout and adaptable design, enabling the battery swapping equipment to be installed and operated stably within confined spaces. Technically, the transporter's guide rail is positioned below the guide support frame, efficiently utilizing vertical space and significantly reducing the overall vertical footprint of the equipment, thus adapting to the vertical height limitations of limited spaces. Simultaneously, the design incorporates a gantry that is longitudinally adjustable along the guide support frame, a transverse lifting transport vehicle that is laterally movable along the gantry, and a transverse transporter that moves longitudinally along the transporter's guide rail. This allows the core operating components of the equipment to flexibly adjust their positions according to the planar range of the limited space, avoiding exceeding spatial boundaries. This effectively solves the problem of existing standard equipment being unable to adapt to limited spaces due to its fixed dimensions. It not only allows the battery swapping equipment to be deployed smoothly within limited spaces but also enables the stable completion of the entire process of grabbing, transferring, and disassembling heavy-duty truck batteries, ensuring battery swapping efficiency and equipment stability.

[0024] Please see Figures 1 to 5This invention proposes a heavy-duty truck battery swapping device 10 for use in confined spaces within existing buildings. The heavy-duty truck battery swapping device 10 includes: a guide rail accessory 110, which includes a guide support frame 111 and a transporter guide rail 112, the transporter guide rail 112 being disposed below the guide support frame 111; and a gantry frame 120, which is disposed above the guide support frame 111 and connected to it for longitudinal movement along the guide support frame 111. Position adjustment; a transverse lifting transport vehicle 130, which is connected to the gantry frame 120, moves laterally along the gantry frame 120, and is equipped with a lifting drive mechanism; a battery gripping platform 140, which is located below the transverse lifting transport vehicle 130, moves up and down under the drive of the lifting drive mechanism, and is used to perform battery gripping and releasing actions; a transverse transporter 150, which is connected to the transporter guide rail 112, moves longitudinally along the transporter guide rail 112.

[0025] In this embodiment, the driving direction of the heavy truck 160 entering the battery swapping area is taken as the longitudinal direction, the horizontal direction perpendicular to this longitudinal direction is taken as the lateral direction, and the vertical direction is taken as the lifting direction. The specific process of heavy truck battery swapping in the limited space of the existing building is as follows: Heavy truck parking and equipment alignment: The heavy truck 160 to be swapped enters the battery swapping area and parks at the working position below the guide support frame 111. According to the alignment reference information (i.e., the relative position information between the gantry 120 and the heavy truck battery compartment), the gantry 120 is longitudinally adjusted along the guide support frame 111 and moved to a position corresponding to the longitudinal orientation of the heavy truck battery compartment of the heavy truck 160 to be swapped. The transverse lifting transport vehicle 130 moves laterally along the gantry 120 and moves to directly above the heavy truck battery compartment, completing the spatial alignment of the battery swapping operation. Battery disassembly and transfer: The lifting drive mechanism drives the battery gripping platform 140 to descend to the battery gripping position. After gripping the heavy truck's primary battery, the battery gripping platform 140 is driven to rise. The transverse lifting transport vehicle 130 moves laterally along the gantry frame 120 to a position above the transverse transporter 150. The lifting drive mechanism drives the battery gripping platform 140 to descend, releasing the heavy truck's primary battery onto the transverse transporter 150. The transverse transporter 150 moves longitudinally along the transporter guide rail 112, transferring the heavy truck's primary battery to a preset storage position. New battery retrieval and installation: The transverse transporter 150 moves the new battery longitudinally to below the battery gripping platform 140. After the lifting drive mechanism drives the battery gripping platform 140 to descend and grip the new battery, it drives the battery gripping platform 140 to rise. The transverse lifting transporter 130 moves laterally along the gantry 120 to above the heavy truck battery compartment. The lifting drive mechanism drives the battery gripping platform 140 to descend and send the new battery into the heavy truck battery compartment. The battery gripping platform 140 then performs the new battery release action and subsequently rises to reset under the drive of the lifting drive mechanism. Equipment reset: The transverse lifting transport vehicle 130 resets along the gantry frame 120, the gantry frame 120 resets along the guide support frame 111, the battery swapping heavy truck 160 leaves the battery swapping area, and the battery swapping process ends.

[0026] Preferably, the heavy-duty truck battery swapping equipment 10 is provided with an enclosure wall 170 on its outer side (see details). Figure 6 The enclosure wall 170 is provided with an entrance and exit, through which the heavy truck 160 waiting to be swapped enters or leaves the battery swapping area.

[0027] In one embodiment, such as Figure 2 As shown, a camera is installed on the gantry 120, and the camera is used to acquire the alignment reference information of the heavy truck 160 to be battery swapped.

[0028] In this embodiment, a camera is installed on the gantry 120. The camera is used to acquire the alignment reference information of the heavy truck 160 to be swapped (i.e., the relative position information between the gantry 120 and the heavy truck battery compartment), generate longitudinal adjustment parameters based on the alignment reference information, and adjust the longitudinal position of the gantry 120 based on the longitudinal adjustment parameters so that it moves to a position corresponding to the longitudinal orientation of the heavy truck battery compartment.

[0029] In one embodiment, such as Figure 2 and Figure 6 As shown, a laser sensor is installed on the battery gripping platform 140, which is used to detect the tilt angle information between the new battery and the heavy truck battery compartment.

[0030] In this embodiment, a laser sensor is installed on the battery gripping platform 140. The laser sensor is used to detect the tilt angle information between the new battery and the heavy truck battery compartment. Based on the tilt angle information, lateral adjustment parameters and descent adjustment parameters are generated. Based on the lateral adjustment parameters, the lateral position of the transverse lifting transport vehicle 130 is adjusted so that it moves directly above the heavy truck battery compartment. Based on the descent adjustment parameters, the descent height of the battery gripping platform 140 is adjusted. The descent stops when the battery gripping position is reached.

[0031] In one embodiment, such as Figure 3 and Figure 4 As shown, the lifting drive mechanism includes a lifting motor 131 and a drum 132. The drum 132 rotates under the drive of the lifting motor 131. A movable pulley 141 is fixedly arranged below the battery gripping platform 140, and the drum 132 is connected to the movable pulley 141 through a flexible transmission component.

[0032] In this embodiment, the lifting drive mechanism includes a lifting motor 131 and a drum 132. The drum 132 rotates under the drive of the lifting motor 131. Several movable pulleys 141 are fixedly arranged below the battery gripping platform 140. The drum 132 is connected to each of the movable pulleys 141 via several flexible transmission components (such as steel wire ropes). One end of each flexible transmission component is fixed to the frame of the transverse lifting transport vehicle 130, and the other end passes around the corresponding movable pulley 141 and winds around the drum 132. When it is necessary to drive the battery gripping platform 140 to rise or fall, the lifting motor 131 drives the drum 132 to rotate in the forward or reverse direction, and the coordinated action of the movable pulleys 141 drives the battery gripping platform 140 to rise or fall vertically.

[0033] Preferably, the lifting drive mechanism further includes a lifting reducer. When it is necessary to drive the battery grabbing platform 140 to lift, the lifting motor 131 outputs power, which is reduced and increased in torque by the lifting reducer to drive the drum 132 to rotate in the forward or reverse direction.

[0034] In one embodiment, such as Figure 3 and Figure 4 As shown, both sides of the battery gripping platform 140 are provided with electric push rods 142 and hooks 143 that are connected to the electric push rods 142 in a transmission manner. The hooks 143 rotate under the drive of the electric push rods 142.

[0035] In this embodiment, electric push rods 142 are provided on both sides of the battery gripping platform 140. Each electric push rod 142 is connected to a number of hooks 143. The number of hooks 143 can be flexibly set according to the mounting point requirements of the heavy truck battery.

[0036] When a battery gripping or releasing action is required, the electric push rod 142 drives the hook 143 to rotate to engage or disengage with the battery mounting part.

[0037] In one embodiment, such as Figure 2 As shown, a protective railing 113 is provided below the guide support frame 111, and the protective railing 113 is provided on one side of the transporter guide rail 112 along the extension direction of the transporter guide rail 112.

[0038] In this embodiment, a protective guardrail 113 is provided below the guide support frame 111. The protective guardrail 113 is provided on one side of the transporter guide rail 112 along the extension direction of the transporter guide rail 112. The protective guardrail 113 encloses and forms a battery swapping area. The heavy truck 160 to be swapped drives into the battery swapping area and stops at the preset working position.

[0039] In one embodiment, such as Figure 1 As shown, a protective fence 114 is provided on the outer side of the transporter guide rail 112.

[0040] In this embodiment, a protective fence 114 is provided on the outer side of the transporter guide rail 112 to prevent non-operating personnel, tools or other foreign objects from approaching or entering the running path of the transverse transporter 150 from the outside, further ensuring the safety of the transverse transporter 150 during the transfer of heavy truck batteries and avoiding interference with the external environment.

[0041] In one embodiment, such as Figure 5 As shown, the transverse transporter 150 is provided with a guide assembly 151.

[0042] In this embodiment, the transverse transporter 150 is provided with a plurality of guide components 151. The guide components 151 may take the form of protrusions, limiting plates or guide strips, etc., to accurately limit the placement position of the heavy truck battery and improve the stability of the transfer process.

[0043] The transverse transporter is also equipped with a battery placement detection switch. When the heavy truck battery is placed on the transverse transporter 150 by the guide component 151, the battery placement detection switch can detect in real time whether the heavy truck battery is accurately placed in place. After confirming that the heavy truck battery is placed stably, a signal is sent to ensure that the heavy truck battery is in a preset safe state when the transverse transporter 150 starts to transport, avoiding the risk of falling off during the transport process due to placement deviation, and further ensuring the accuracy and safety of the operation.

[0044] In one embodiment, such as Figure 1 , Figure 4 and Figure 5As shown, a servo cylinder 121 is installed on the gantry frame 120, and the gantry frame 120 is adjusted longitudinally along the guide support frame 111 under the drive of the servo cylinder 121; a first transverse motor 133 is installed on the transverse lifting transport vehicle 130, and the transverse lifting transport vehicle 130 moves laterally along the gantry frame 120 under the drive of the first transverse motor 133; a second transverse motor 152 is installed on the transverse transporter 150, and the transverse transporter 150 moves longitudinally along the transporter guide rail 112 under the drive of the second transverse motor 152.

[0045] In this embodiment, a first guide rail is provided above the guide support frame 111, and the gantry frame 120 is connected to the first guide rail. Under the drive of the servo cylinder 121, the gantry frame 120 adjusts its longitudinal position along the first guide rail.

[0046] A second guide rail is provided above the gantry frame 120. The transverse lifting transport vehicle 130 is connected to the second guide rail. Driven by the first transverse motor 133, the transverse lifting transport vehicle 130 can move laterally along the second guide rail. Preferably, the transverse lifting transport vehicle 130 is also equipped with a transverse reducer. After the first transverse motor 133 provides power, the transverse reducer reduces speed and increases torque, allowing the transverse lifting transport vehicle 130 to move smoothly laterally along the second guide rail.

[0047] The transverse transporter 150 is equipped with a second transverse motor 152. The transverse transporter 150 is connected to the transporter guide rail 112. Driven by the second transverse motor 152, the transverse transporter 150 moves longitudinally along the transporter guide rail 112 to complete the transfer operation of the heavy truck battery.

[0048] This invention also provides a method for battery swapping of heavy-duty trucks within the limited space of an existing building. This method is applied to the aforementioned battery swapping equipment for heavy-duty trucks within the limited space of an existing building. Figure 7 As shown, the method includes steps S110-S140: S110. The heavy truck to be swapped enters the battery swapping area and stops at the working position. According to the alignment reference information obtained by the camera, the gantry is longitudinally adjusted along the guide support frame to form a longitudinal fit with the heavy truck battery compartment. The transverse lifting transport vehicle moves laterally along the gantry and moves to directly above the heavy truck battery compartment. S120, the lifting drive mechanism drives the battery gripping platform to descend to the battery gripping position, performs the gripping of the heavy truck's primary battery and then rises, the transverse lifting transport vehicle moves laterally to the position above the transverse transporter, the lifting drive mechanism drives the battery gripping platform to descend, release the heavy truck's primary battery onto the transverse transporter, the transverse transporter moves longitudinally along the transporter guide rail, and transfers the heavy truck's primary battery to the preset storage position; S130, the transverse transporter moves the new battery it carries longitudinally to below the battery gripping platform, the lifting drive mechanism drives the battery gripping platform to descend and grip the new battery and then rises, the transverse lifting transporter moves laterally to above the heavy truck battery compartment, the lifting drive mechanism drives the battery gripping platform to descend and send the new battery into the heavy truck battery compartment, and the battery gripping platform releases the new battery and then resets. S140, the lateral lifting transport vehicle resets along the gantry, the gantry resets along the guide support frame, the heavy truck to be swapped leaves the swapping area, and the swapping process ends.

[0049] In this embodiment, the driving direction of the heavy truck entering the battery swapping area is taken as the longitudinal direction, the horizontal direction perpendicular to this longitudinal direction is taken as the lateral direction, and the vertical direction is taken as the lifting direction. The specific process of heavy truck battery swapping in the limited space of an existing building is as follows: Heavy truck parking and equipment alignment: The heavy truck to be swapped drives into the battery swapping area and parks at the working position below the guide support frame.

The transverse lifting transporter moves laterally along the gantry to above the heavy truck battery compartment. The lifting drive mechanism drives the battery gripping platform to descend and send the new battery into the heavy truck battery compartment. The battery gripping platform then performs the new battery release action and subsequently rises to reset under the drive of the lifting drive mechanism. Equipment reset: The lateral lifting transport vehicle resets along the gantry, and the gantry resets along the guide support frame.
