[0049] The present application will be described in further detail below with reference to the accompanying drawings. Figures 1 to 6 illustrate.

[0050] Example 1

[0051] This embodiment provides a battery assembly locking mechanism for a scraper, which is used in a scraper. Specifically, Figures 1 to 6 As shown, it includes a battery assembly 1, a locking mechanism 2 and a sensing device 3. The locking mechanism 2 is connected to the vehicle body and is arranged between the vehicle body and the battery assembly 1. The locking mechanism 2 can lock or unlock the battery assembly 1 and the vehicle body. The sensing device 3 can sense the working status of the locking mechanism 2 and, at the same time, transmit the working status information of the locking mechanism 2 to the control console of the cab, so that the staff in the cab can obtain information on whether the battery assembly 1 is locked on the vehicle body without leaving the cab. Then, when the staff needs to replace the battery assembly 1, they can operate the drive assembly 21 in the cab to open or lock the locking assembly 23 to unlock or lock the battery assembly 1.

[0052] Specifically, such as Figures 1 to 2 As shown, the battery assembly 1 includes a battery pack and a mounting base 11, the mounting base 11 is connected to the vehicle body, and the sensing device 3 is arranged on the mounting base 11, the sensing device 3 is used to sense and transmit the working status information of the locking mechanism 2, wherein the locking mechanism 2 includes a driving component 21 and a locking component 23, the locking component 23 is a locking pin shaft, the driving component 21 is connected to the locking component 23, the driving component 21 is used to drive the locking component 23 to lock or unlock the mounting base 11, and the mounting base 11 can be conveniently and reliably fixed by driving the locking component 23 by the driving component 21; when the battery assembly 1 needs to be replaced, the locking component 23 is driven by the driving component 21, and the fixed state of the mounting base 11 can be quickly released, without the operator having to lock the battery assembly 1 with bolts or other fasteners, or loosen it, etc., which can simplify the installation and replacement process of the battery assembly 1, improve the replacement efficiency of the battery assembly 1, and improve the operating time and work efficiency of the scraper.

[0053] Further, such as Figures 3 to 5As shown, the mounting base 11 is provided with a limit portion 111 that cooperates with the locking mechanism 2. The limit portion 111 is provided at one end of the mounting base 11 near the locking assembly 23. The limit portion 111 is provided with a socket for the locking assembly 23 to pass through. The driving assembly 21 drives the locking assembly 23 through the socket to connect with the sensing device 3. The sensing device 3 then transmits the working status information of the locking mechanism 2 to the work surface of the cab, so that the staff in the cab can know whether the battery assembly 1 is locked on the vehicle body without the need for a cab. The mounting base 11 also includes a fixing plate 112. The limit portion 111 is vertically connected to the fixing plate 112. The fixing plate 112 is provided with a guide pin 113 at the bottom. The guide pin 113 is connected to the fixing plate 112. The guide pin 113 can not only be used to locate and guide the movement direction of the locking mechanism 2, but also prevent the mounting base 11 from shaking or moving during transportation or use, which helps to improve the stability and safety of the battery assembly 1.

[0054] like Figure 5 As shown, the jack includes a coaxially arranged guide hole 1111 and a locking hole 1112. The guide hole 1111 is arranged on a side close to the driving component 21. When the driving component 21 drives the locking component 23, the locking component 23 passes through the guide hole 1111 and the locking hole 1112 in turn and is connected to the sensing device 3. The guide hole 1111 is a conical structure, and the side wall of the guide hole 1111 is an inclined surface. The aperture of the guide hole 1111 is D1, and the aperture of the locking hole 1112 is D2, wherein D1>D2. By setting the guide hole 1111, it is beneficial to provide a larger fault tolerance space for the locking component 23, ensuring that the locking component 23 can correctly pass through the locking hole 1112, and can also reduce friction and resistance during installation, improve installation efficiency, and simplify processing.

[0055] In this embodiment, if Figure 3 As shown, it also includes a fixed base 4, one side of the fixed base 4 is connected to the locking mechanism 2, and the other side is connected to the vehicle body, and the fixed base 4 is connected to the vehicle body by bolts; wherein, the fixed base 4 includes a side plate 42 and a bottom plate 41, the side plate 42 is vertically connected to the bottom plate 41, the side plates 42 are arranged on opposite sides of the bottom plate 41, and the side plates 42 are provided with connecting holes for the locking assembly 23 to pass through, the connecting holes and the sockets on the limiting portion 111 are respectively on the same straight line, and the sockets and the connecting holes are arranged correspondingly, the shape and size of the locking assembly 23 are consistent with the connecting holes, and the connecting holes have a guiding function, which is conducive to the driving assembly 21 to pass through the connecting hole and the socket in sequence when driving the locking mechanism, which can simplify the assembly process and also improve the assembly accuracy. Through precise alignment, the matching accuracy between the locking assembly 23 and the connecting hole can be guaranteed, the error is reduced, and the assembly quality is improved.

[0056] Further, such as Figure 4As shown, the drive assembly 21 is a drive cylinder or air cylinder. The drive cylinder is a double-piston hydraulic cylinder. The drive cylinder includes a cylinder body 211 and a piston rod 212. The ends of the cylinder body 211 are connected to the piston rod 212. The ends of the piston rod 212 are arc-shaped structures. The piston rods 212 are arranged on both sides of the cylinder body 211 near the locking assembly 23. The cylinder body 211 is provided with a piston. One end of the piston rod 212 is connected to the piston and the other end is connected to the locking assembly 23. The piston rod 212 is used to transmit the pressure of the piston to the locking assembly 23. The bottom of the cylinder body 211 is connected to the fixed base 4. The length of the piston rod 212 when driven is L1, and the length from the cylinder body 211 to the side plate 42 is L2, where L1>L2. A stop ring 215 or protrusion is provided on the piston rod 212. The diameter of the stop ring 215 is larger than the outer diameter of the locking assembly 23. The stop ring 215 is sleeved onto the piston rod 212. When the piston rod 212 moves toward the mounting base 11, the stop ring 215 can be used to limit the extension of the piston rod 212, preventing the piston rod 212 from extending too long or retracting into the cylinder 211 and becoming difficult to remove, thereby helping to limit the length of the piston rod 212 to a controllable range. The bottom of the cylinder 211 is provided with fixed legs 216. There are at least a plurality of fixed legs 216, which are arranged on both sides of the cylinder and are symmetrically arranged to provide more uniform support and force distribution, reducing the possibility of tilting and shaking. The fixed legs 216 are provided with bolt holes, and the fixed base 4 is connected to the fixed legs 216 through the bolt holes with bolts, thereby enhancing the stability of the cylinder 211.

[0057] like Figure 4 As shown, the cylinder body 211 is provided with an oil inlet 213 and an oil outlet 214, there are two oil inlets 213 and two oil outlets 214, the cylinder body 211 includes a rodless chamber and a rod chamber, the piston is arranged in the rod chamber, and the piston is connected to the piston rod 212 through the rod chamber. When the hydraulic oil enters the rodless chamber from the oil inlet 213, the piston rod 212 will push the locking assembly 23 to move along the axial direction of the jack, extend into the locking hole 1112 through the guide hole 1111, and connect with the sensing device 3, thereby realizing the locking of the mounting base 11 and pushing the sensing device 3 to transmit to the control console surface in the cab. The information that the battery assembly 1 has been locked is transmitted; when the battery assembly 1 needs to be replaced, when the hydraulic cylinder enters the rodless cavity from the oil outlet 214 on both sides, the hydraulic oil pushes the piston rod 212 to drag the locking assembly 23 back to its original position, thereby unlocking the mounting base 11. The sensing device 3 transmits the information that the mounting base 11 has been locked to the control console surface in the cab, and maintenance personnel do not need to perform additional locking with bolts or other fasteners, which can simplify the installation and replacement process of the battery assembly 1, improve the replacement efficiency of the battery assembly 1, and improve the operating time and work efficiency of the scraper.

[0058] In this embodiment, if Figure 3 As shown, the locking assembly 23 is rotatably connected to the driving assembly 21 through the fastening assembly 5. The locking assembly 23 is provided with a positioning groove adapted to the piston rod 212. The end of the piston rod 212 is placed in the positioning groove and then fixed by the fastening assembly 5, thereby realizing a rotational connection, preventing the piston rod 212 and the locking assembly 23 from loosening, and strengthening the connection strength between the piston rod 212 and the locking assembly 23. After using the locking assembly 23 for a long time, when the locking assembly 23 is worn, a new locking assembly 23 can be replaced in time without the need to disassemble and repair the entire locking assembly 23. The size of the locking assembly 23 can be replaced according to the needs of the vehicle, and disassembly and assembly are convenient, which improves the efficiency and flexibility of use and saves costs. A first mounting hole is provided on the locking assembly 23, and a second mounting hole is provided on the piston rod 212. The first mounting hole and the second mounting hole are arranged correspondingly, and the size and shape of the first mounting hole and the second mounting hole are consistent and adapted. The fastening assembly 5 includes a pin 51 and a cotter pin 52. A hole for inserting the cotter pin 52 is provided at one end of the pin 51. The pin 51 passes through the first mounting hole and the second mounting hole in turn, and the cotter pin 52 is inserted into the hole of the pin 51, which can fix the piston rod 212 and the locking assembly 23. The diameter of the pin 51 away from the cotter pin 52 is larger than the outer diameter of the first mounting hole, which can prevent the pin 51 from easily falling out of the first mounting hole and increase the connection strength.

[0059] Example 2

[0060] This embodiment is different from the first embodiment in that, in this embodiment, the aperture and size of the guide hole 1111 and the locking hole 1112 are consistent, the locking assembly 23 passes through the socket in turn and is connected to the sensing device 3, the driving assembly 21 drives the locking assembly 23 to pass through the socket and connect to the sensing device 3, and the sensing device 3 then transmits the working status information of the locking mechanism 2 to the work surface of the cab, so that the staff in the cab can obtain information on whether the battery assembly 1 is locked on the vehicle body without the need for a cab.
