Description

Technical Field

[0001] The present invention relates to the technical field of battery locking for new energy mining vehicles, and in particular to a battery locking mechanism for a battery replacement system of a new energy mining dump truck. Background Art

[0002] As the application of new energy technologies in the field of mining dump trucks continues to expand, the battery swap model has attracted much attention due to its efficient and rapid energy replenishment characteristics.

[0003] However, the existing battery locking mechanism has many shortcomings. Traditional mechanical locking methods often have defects in reliability. The existing battery locking device mainly relies on two front and rear baffles and two shackles on the left and right sides to fix the battery box with large size and weight. This design has certain safety hazards during vehicle operation. In the harsh working environment of mining dump trucks, such as long-term bumps, frequent heavy-load starting and braking, the battery box may become loose during operation due to insufficient locking strength. Once loose, the battery pack may shift, affecting the stability of the electrical connection, and even causing safety hazards, such as electric sparks caused by poor contact, which will affect the normal operation of the vehicle and even cause safety accidents.

[0004] In addition, the replacement of the battery box needs to be carried out by hoisting, which requires the upper and lower components of the four sets of shackles to be precisely aligned, which is difficult to operate. It is difficult for unskilled operators to complete the alignment and buckling, which is time-consuming and laborious. At the same time, some existing locking mechanisms have complex structures and are inconvenient to operate, which not only increases the manufacturing cost of the vehicle, but also requires a lot of manpower and time costs during maintenance and repair, reducing the overall operating efficiency of the vehicle.

[0005] In addition, most of the existing battery locking mechanisms set the locking tongues on both sides of the battery frame and the locking buckles at the corresponding positions on the bottom bracket of the battery frame. They have poor compatibility with batteries of different specifications. When other types of batteries need to be replaced, they may not be well adapted and the locking mechanism needs to be modified or replaced. It is difficult to adapt to the continuous development and diversification of new energy mining dump truck battery technology. Summary of the invention

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 an indirect connection through an intermediate medium, or it can be the internal communication of two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood in combination with specific circumstances.

[0064] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0065] This embodiment relates to a battery locking mechanism for a new energy mining dump truck battery replacement system. Figures 1 to 8 As shown, the locking mechanism includes a first locking assembly 1 connected to the battery frame, and a second locking assembly 2 connected to the battery frame bottom bracket 3. The first locking assembly 1 includes a first support seat 101 and a plug-in connector 102, and the second locking assembly 2 includes a second support seat 201, a socket member 202 pivotally connected to the support seat, and a driving assembly 203 for locking the socket member 202. A socket slot 2021 is formed on the socket member 202, and when in a free state, the socket slot 2021 opens upward.

[0066] When the connector 102 moves toward the socket 202, the connector 102 is inserted into the socket slot 2021, and the socket 202 rotates relative to the second support seat 201 as the connector 102 continues to move downward, so that the opening of the socket slot 2021 rotates to a preset angle and is in a locked state; the power output end of the drive component 203 abuts against the socket 202, and the socket 202 is locked by the drive component 203 and the connector 102.

[0067] The battery locking mechanism of the new energy mining dump truck battery replacement system described in this embodiment is configured by setting a first locking component 1 on the battery frame, and a second locking component on the battery frame base 3. The first locking component 1 is connected to the battery frame through a first support seat 101, and the second locking component is connected to the battery frame base 3 through a second support seat 201, so as to adapt to the needs of adjusting the locking position of batteries of different specifications.

[0068] At the same time, the connector 102 is lowered into the socket slot 2021 along with the battery box, and the gravity of the battery box is used to drive the socket slot 202 to rotate relative to the second support seat 201, so that the opening of the socket slot 2021 rotates a preset angle to limit the displacement of the connector 102, and the power output end of the driving component 203 abuts against the socket slot 202 to lock the socket slot 202 to prevent the socket slot 202 from rotating and causing the battery box and the battery rack base 3 to be displaced and misaligned.

[0069] The locking mechanism has a simple structure and few parts, which not only reduces the installation and disassembly steps of the staff, improves the installation efficiency, but also reduces the manufacturing cost of the locking mechanism. In addition, by inserting the connector 102 into the socket 2021, the positioning effect is improved, ensuring the stability of the use of the new energy mining dump truck battery replacement system.

[0070] Based on the above overall introduction, an exemplary structure of the battery locking mechanism of the new energy mining dump truck battery replacement system of this embodiment is as follows: Figure 1 As shown, six locking mechanisms arranged at intervals are provided on the battery rack base 3, the battery rack base 3 is installed on the vehicle frame, the second support seat 201 is connected to the battery rack base 3, and the battery box frame is connected to the first support frame. The first support seat 101 of this embodiment includes a flat plate and a vertical plate vertically connected to the flat plate, the two vertical plates are arranged at intervals, and the space between the two vertical plates is used to accommodate the second support seat 201 in the locked state to improve the positioning accuracy. The first support seat 101 is fixed to the battery box frame by welding the flat plate. In other embodiments, it can also be fixed by bolt connection.

[0071] As a preferred implementation mode, Figures 2 to 7 As shown, the second locking assembly 2 also includes an elastic member 204, a fixing column 205 is provided on the second support seat 201, one end of the elastic member 204 is connected to the fixing column 205, and the other end is connected to the socket 202. The elastic member 204 of this embodiment adopts a telescopic tension spring, which is fixed with an arc groove for one end of the elastic member 204 to be clamped, so as to prevent the elastic member 204 from moving up and down along the axial direction of the fixing column 205. Figure 7 As shown, the socket 202 is provided with a flange portion, and the other end of the elastic member 204 is connected to the flange portion. When the locking mechanism is in a free state, the elastic member 204 is in a free state. When the locking mechanism is in a locked state, the elastic member 204 is stretched and stores energy. When it is necessary to change from the locked state to the free state, the driving component 203 moves away from the socket 202, and the connector 102 rotates due to the upward movement of the battery box. The elastic member 204 releases energy to reset the socket 202 to the free state.

[0072] like Figures 2 to 8 As shown, the second support seat 201 includes two L-shaped plates arranged opposite to each other, and a plurality of support columns 206 arranged on the L-shaped plates. Threaded sections are arranged at both ends of the support column 206, and sleeves 207 are sleeved on the outside of the support column 206. Both ends of the sleeve 207 abut between the two L-shaped plates, and nuts are sleeved on the threaded sections, and the nuts abut on the L-shaped plates. The sleeve 207 is arranged to facilitate the control of the thickness of the second support seat 201, and to facilitate the adjustment of the gap between the first support seat 101 and the second support seat 201, so as to ensure that the connector 102 is smoothly inserted into the socket 2021 when the first support seat 101 moves downward, thereby improving the positioning accuracy.

[0073] Furthermore, if Figures 2 to 6 As shown, the L-shaped plate includes a longitudinal plate 2011 and a transverse plate 2012 connected to each other, the driving assembly 203 and the socket 202 are both arranged on the longitudinal plate 2011, and the upper end of the longitudinal plate 2011 is also provided with an open groove 20111 for accommodating the plug-in component 102, and the transverse plate 2012 is provided with a first mounting portion 20121 connected to the battery rack base 3, and the second support seat 201 is connected and fixed to the battery rack base 3 through the first mounting portion 20121. The first mounting portion 20121 of this embodiment is a plurality of circular holes arranged at intervals on the transverse plate 2012, and the second support seat 201 is connected to the battery rack base 3 by bolt connection.

[0074] Furthermore, if Figures 2 to 4 As shown, the opening groove 20111 includes a tapered section 20112 opening upward, and a vertical section 20113; the width of the upper end of the tapered section 20112 is greater than that of the lower end, and the width of the vertical section 20113 is equal to the width of the lower end of the tapered section 20112. The plug-in connector 102 includes a connecting column 1021, a plug-in barrel 1022 sleeved on the outer side of the connecting column 1021, and the width of the vertical section 20113 is adapted to the outer diameter of the plug-in barrel 1022. The setting of the tapered section 20112 can guide the socket 202 into the vertical section 20113 through the guidance of the tapered section 20112 when the positions of the first locking assembly 1 and the second locking assembly 2 do not correspond, when the battery box moves downward, so as to achieve the purpose of accurate positioning.

[0075] Preferably, if Figures 2 to 8 As shown, the driving assembly 203 includes a driving part 2031 pivotally connected to the second support seat 201, and a locking member 2032 connected to the power output end of the driving part 2031. A mounting shaft 2033 is also provided between the two L-shaped plates. The locking member 2032 is sleeved on the mounting shaft 2033. The driving part 2031 drives the locking member 2032 to rotate along the mounting shaft 2033 so that the locking member 2032 abuts against the socket 202. The driving part 2031 adopts a hydraulic pump, and the hydraulic pump is controlled by a controller to rotate forward or reverse so that the locking member 2032 abuts against or moves away from the socket 202.

[0076] In order to improve the locking effect, Figure 7 and Figure 8 As shown, the socket component 202 is provided with a first abutting surface 2022, and the locking component 2032 is provided with a second abutting surface 20321. The first abutting surface 2022 is connected to the notch on one side of the socket slot 2021. When the first abutting surface 2022 is abutted and connected with the second abutting surface 20321, the locking mechanism is in a locked state.

[0077] Furthermore, if Figure 7As shown, the socket 202 is also provided with a first fillet 2023, the first abutting surface 2022 is connected to the first fillet 2023, the locking member 2032 is also provided with a second fillet 20322, the second abutting surface 20321 is connected to the second fillet 20322, the radius of the first fillet 2023 is 5mm or 10mm, and the radius of the second fillet 20322 is 10mm or 5mm. Such an arrangement ensures that the locking member 2032 and the socket 202 move smoothly without jamming during the locking or disengagement of the battery box and the battery rack base 3.

[0078] In addition, if Figures 4 to 8 As shown, a first fixed shaft 208 is further provided between the two L-shaped plates, and a mounting seat 209 is provided at the fixed end of the driving part 2031, and the mounting seat 209 is sleeved on the first fixed shaft 208. First limiting sleeves 210 are respectively provided at both ends of the mounting seat 209, and the first limiting sleeves 210 abut between the L-shaped plate and the mounting seat 209; the first limiting sleeves 210 are sleeved on the first fixed shaft 208. By providing the first limiting sleeves 210, the axial position of the driving part 2031 along the first fixed shaft 208 can be adjusted to ensure the smoothness of the movement of the locking member 2032 and the driving part 2031.

[0079] In addition, Figures 4 to 8 As shown, the second limiting sleeve 211 is sleeved on the outer side of the installation shaft 2033, and the second limiting sleeve 211 abuts between the L-shaped plate and the locking member 2032. A second fixed shaft 212 is also provided between the two L-shaped plates, and the socket 202 is sleeved on the second fixed shaft 212. A third limiting sleeve 213 is provided on both sides of the socket 202, and the third limiting sleeve 213 abuts between the L-shaped plate and the socket 202. By providing the second limiting sleeve 211 and the third limiting sleeve 213, the contact area between the locking member 2032 and the socket 202 can be adjusted to ensure the locking effect.

[0080] The controller of the battery locking mechanism of the battery replacement system of the new energy mining dump truck of this embodiment adopts control elements such as PLC. In addition, a pressure sensor for real-time monitoring of the pressure value of the hydraulic system is provided inside the driving unit 2031 or on the hydraulic pipeline. The pressure sensor transmits data to the controller. When the pressure reaches the preset safe and stable locking pressure value, the controller stops the hydraulic pump. The controller accurately controls the working state of the hydraulic pump according to the preset pressure value range and the data fed back by the pressure sensor, thereby adjusting the action of the hydraulic cylinder and realizing precise control of the battery locking force.
