Description

Technical Field

[0001] This utility model belongs to the field of new energy battery swapping station technology, and in particular relates to a support leg heavy truck swapping station. Background Technology

[0002] Existing battery swapping stations typically include a gantry crane assembly for transferring batteries between the vehicle and the swapping station for charging, and a lifting device assembly for grabbing batteries. Due to factors such as cost, space requirements, and mobility, the connection between the gantry crane assembly and the lifting device assembly can be achieved by means of slings.

[0003] In daily use, the applicant found that when connecting the gantry crane assembly and the spreader assembly via a hoisting rope, the inertia generated by the horizontal movement of the gantry crane assembly causes a waiting period for the spreader assembly to stabilize before it can operate when controlling the spreader assembly to grab or place batteries. This undoubtedly increases the battery swapping time. Therefore, a solution is needed to improve or solve the above problem. Utility Model Content

[0004] The purpose of this invention is to provide a support leg type heavy truck battery swapping station to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, one technical solution adopted by this utility model is: a support-type heavy truck battery swapping station, including a battery swapping container, wherein the battery swapping container is provided with a battery charging position, a gantry crane assembly and a lifting system; The gantry assembly includes a running frame, a horizontal dual-axis moving assembly mounted on the running frame, and a lifting assembly installed at the working end of the horizontal dual-axis moving assembly. The lifting assembly includes a mounting base, a hoisting rope, and a hoisting rope retraction assembly installed on the mounting base. The lifting system includes a connecting plate and an unlocking / unlocking assembly disposed on the bottom surface of the connecting plate, and the lifting rope is connected to the connecting plate so that it is in a horizontal state; At least two connecting posts are fixed on the top surface of the connecting plate, and an flared socket is provided on the mounting base so that the connecting plate can be inserted after it is lifted.

[0006] Preferably, the battery charging position includes a horizontal dual-axis guide limiting post, a plug-in port, and a positioning post. Several horizontal dual-axis guide limiting posts are provided and form a battery placement space. The battery slides into the battery placement space guided by the horizontal dual-axis guide limiting posts. The battery has a plug head for use with the plug-in port and a positioning hole for use with the positioning post.

[0007] Preferably, the unlocking / unlocking assembly includes several rotating blocks and a rotation drive assembly. The rotating blocks are rotatably connected to the connecting plate, and the rotation drive assembly is used to drive the rotating blocks to rotate so as to achieve engagement with the battery. The battery has an engagement part that cooperates with the rotating blocks.

[0008] Preferably, each pair of rotating blocks forms a group, and one rotation drive assembly drives a group of rotating blocks. Each rotating block has a gear fixed at one end. The rotation drive assembly is an electric push rod, and the working end of the electric push rod has two racks fixed. Each rack meshes with a gear on a rotating block. The electric push rod drives the two racks to move so that the two rotating blocks rotate, thereby simultaneously locking or unlocking the battery.

[0009] Preferably, a Y-axis guide rail is fixed on the running frame, an X-axis mounting bracket slides on the Y-axis guide rail, the mounting seat slides on the X-axis mounting bracket in the X-axis direction, a Y-axis drive assembly for controlling its movement on the Y-axis guide rail is mounted on the X-axis mounting bracket, and an X-axis drive assembly for controlling its movement along the X-axis direction on the X-axis mounting bracket is mounted on the mounting seat.

[0010] Preferably, a ventilation plate is installed vertically on the X-axis mounting bracket, and the plane containing the length and width of the ventilation plate is set perpendicular to the Y-axis guide rail.

[0011] Preferably, the ventilation plate includes a fixed plate and a telescopic plate, the telescopic plate slides down along the fixed plate, and a telescopic drive assembly for driving the movement of the telescopic plate is installed on the X-axis mounting bracket.

[0012] Preferably, the battery swapping container is also equipped with a charging pile, which is electrically connected to the battery charging station.

[0013] The beneficial effects of this utility model are as follows: This solution sets at least two connecting columns on the connecting plate and provides an flared socket on the mounting base so that it can be inserted after the connecting plate is lifted. When the gantry assembly moves to the position that needs to be lifted, the insertion process makes the lifting assembly fast and stable, thus improving the battery swapping efficiency. Conventional battery swapping stations require cooling systems to reduce the heat generated by battery charging inside the swapping container. However, in some regions, such as northern regions, the ambient temperature is generally suitable, and normal air circulation is sufficient to ensure that the temperature inside the swapping container remains within safe limits. Therefore, this solution uses ventilation panels to facilitate rapid air circulation during the swapping process, reducing the safety hazards associated with high temperatures, especially when affected by weather conditions or excessive heat generated by battery charging. This also avoids the need to install unnecessary cooling systems, thus reducing costs. Attached Figure Description

[0015] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0016] Example: See Figure 1-4 A type of outrigger heavy truck battery swapping station includes a battery swapping container 1, wherein the battery swapping container 1 is equipped with a battery charging position 5, a gantry crane assembly 3 and a lifting system; The gantry crane assembly 3 includes a running frame, a horizontal dual-axis moving assembly mounted on the running frame, and a lifting assembly installed at the working end of the horizontal dual-axis moving assembly. The lifting assembly includes a mounting base 34, a hoisting rope, and a hoisting rope retraction assembly 36 mounted on the mounting base 34. (See reference...) Figure 4 , Figure 7 The rope winding and unwinding assembly 36 can be a motor, which drives a roller 37 rotatably connected to the mounting base 34 to rotate. The rope is wound around the roller 37 and is wound and unwinded by the motor. The lifting system includes a connecting plate 61 and an unlocking / unlocking assembly disposed on the bottom surface of the connecting plate 61, and the lifting rope is connected to the connecting plate 61 so that it is in a horizontal state; At least two connecting posts 62 are fixed on the top surface of the connecting plate 61, and the same number of plug-in posts 38 as the connecting posts 62 are fixed on the mounting base 34. The plug-in posts 38 are tubular and have flared openings to facilitate the insertion of the connecting posts 62.

[0017] Among them, see Figure 3 The battery charging station 5 includes a horizontal dual-axis guide limiting post 51, a power inlet 53, and a positioning post 52. Several horizontal dual-axis guide limiting posts 51 are arranged to form a battery placement space. The battery 4 slides into the battery placement space guided by the horizontal dual-axis guide limiting posts 51. The battery has a power plug for use with the power inlet 53 and a positioning hole for use with the positioning post 52. The horizontal dual-axis guide limiting post 51 has a beveled top; its specific location can be found in [reference needed]. Figure 3 set up.

[0018] Among them, see Figure 5 , Figure 6 The unlocking and locking assembly includes several rotating blocks 66 and a rotation drive assembly. The rotating blocks 66 are rotatably connected to the connecting plate 61. The rotation drive assembly is used to drive the rotating blocks 66 to rotate so as to achieve engagement with the battery. The battery has an engagement part that cooperates with the rotating blocks 66.

[0019] In this configuration, every two rotating blocks 66 form a group, and one rotation drive assembly drives a group of rotating blocks 66. Each rotating block 66 has a gear 65 fixed at one end. The rotation drive assembly is an electric push rod 63, and the working end of the electric push rod 63 is fixed with two racks 64. Each rack 64 meshes with a gear 65 on a rotating block 66. The electric push rod 63 drives the two racks 64 to move, so that the two rotating blocks 66 rotate, thereby simultaneously locking or unlocking the battery.

[0020] Among them, see Figure 7 The running frame is fixed with a Y-axis guide rail 31, and an X-axis mounting bracket 32 ​​slides on the Y-axis guide rail 31. The mounting base 34 slides on the X-axis mounting bracket 32 ​​in the X-axis direction. A Y-axis drive assembly 33 is mounted on the X-axis mounting bracket 32 ​​to control its movement on the Y-axis guide rail 31. An X-axis drive assembly 35 is mounted on the mounting base 34 to control its movement along the X-axis direction on the X-axis mounting bracket 32. Both the Y-axis drive assembly 33 and the X-axis drive assembly 35 can be motors. The linear movement components driven by them are conventional means and will not be described further here.

[0021] Among them, see Figure 8 , Figure 9A ventilation plate 7 is vertically mounted on the X-axis mounting bracket 32. The plane containing the length and width of the ventilation plate 7 is perpendicular to the Y-axis guide rail 31. The ventilation plate 7 includes a fixed plate 71 and a telescopic plate 72. Several limiting blocks 73 are fixed on both sides of the fixed plate 71. The telescopic plate 72 can fit against the fixed plate 71 and slide down along the fixed plate 71 by the limiting action of the limiting blocks 73. A telescopic drive assembly 74 for driving the movement of the telescopic plate 72 is mounted on the X-axis mounting bracket 32. Specifically, a vertically arranged rack 76 is fixed on the telescopic plate 72. The telescopic drive assembly 74 can be a motor, and a gear 75 that can mesh with the rack 76 is connected to its output shaft.

[0022] The battery swapping container 1 is also equipped with a charging pile 2, which is electrically connected to the battery charging position 5.

[0023] Working principle and process: When using the battery swapping station of this solution, the gantry crane assembly 3 controls the lifting assembly 6 to be positioned above the vehicle battery (connecting post 62 is inserted into the plug post 38), then the lifting assembly controls the lifting assembly 6 to descend to retrieve the battery, then rises to reset, and then the gantry crane assembly 3 controls the lifting assembly 6 to be positioned above the empty battery charging position 5, and controls the battery to descend for charging. During the above process, since the battery charging inside the battery swapping container 1 generates heat and its air circulation is poor, when the air temperature is suitable but the temperature inside the battery swapping container is high, the air exchange plate 7 can be moved by the gantry assembly 3 during the battery swapping process to allow air circulation inside the battery swapping container 1 and reduce safety hazards. When the temperature inside the battery swapping container is not high, the telescopic plate 72 can be retracted to reduce the operating components of the gantry assembly 3. Temperature monitoring can be carried out by installing a temperature sensor inside the battery swapping container 1.

[0024] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
