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 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, existing battery locking mechanisms have many shortcomings. Traditional mechanical locking methods often have reliability flaws. Existing battery locking devices mainly rely on two front and rear baffles and two shackles on the left and right sides to secure the battery box, which is large in size and weight. This design poses certain safety hazards during vehicle operation. In the harsh working environment of mining dump trucks, such as long periods of 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 creating safety hazards, such as electric sparks caused by poor contact, which may affect the normal operation of the vehicle and even cause safety accidents.

[0004] Furthermore, battery box replacement requires hoisting, which requires precise alignment of the upper and lower components of the four sets of shackles, a complex and challenging task. Alignment and fastening are difficult for unskilled operators, making them time-consuming and labor-intensive. Furthermore, some existing locking mechanisms are complex and difficult to operate, increasing vehicle manufacturing costs while requiring significant labor and time for maintenance and repair, reducing overall vehicle efficiency.

[0005] In addition, most of the existing battery locking mechanisms set the locking tongues on both sides of the battery frame and the lock buckles at the corresponding positions on the bottom bracket of the battery rack. They have poor compatibility with batteries of different specifications. When other models 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 battery technology for new energy mining dump trucks. Summary of the Invention

[0061] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments may be combined with each other.

[0062] In the description of the present invention, it should be noted that the terms "upper," "lower," "inner," and "back" and other terms indicating orientations or positional relationships are based on the orientations or positional relationships shown in the accompanying drawings and are intended solely to facilitate and simplify the description of the present invention. They are not intended to indicate or imply that the devices or components referred to must have, be constructed, or operate in a specific orientation, and therefore should not be construed as limitations on the present invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0063] Furthermore, in the description of the present invention, unless otherwise expressly defined, the terms "mounted," "connected," "connect," and "connector" should be interpreted broadly. For example, these terms may refer to fixed, removable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediary; or internal communication between two components. Those skilled in the art will appreciate the specific meanings of these terms in the present invention based on the 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. As a whole, 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 rack base 3. The first locking assembly 1 includes a first support base 101 and a connector 102. The second locking assembly 2 includes a second support base 201, a socket member 202 pivotally connected to the second support base 201, and a drive assembly 203 for locking the socket member 202. The socket member 202 is formed with a socket slot 2021. 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 exchange system described in this embodiment is configured by arranging a first locking component 1 on the battery frame and a second locking component on the battery rack base 3. The first locking component 1 is connected to the battery frame through a first support base 101, and the second locking component is connected to the battery rack base 3 through a second support base 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 descends into the socket slot 2021 along with the battery box, and the gravity of the battery box drives 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 drive 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 number of installation and removal steps required by the operator, improving installation efficiency, but also reduces the manufacturing cost of the locking mechanism. Furthermore, by inserting the connector 102 into the socket 2021, the positioning effect is improved, ensuring the stability of the battery replacement system for new energy mining dump trucks.

[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 are arranged at intervals on the battery rack base 3. The battery rack base 3 is installed on the vehicle frame. The second support base 201 is connected to the battery rack base 3, and the battery box frame is connected to the first support base. The first support base 101 of this embodiment includes a flat plate and a vertical plate vertically connected to the flat plate. The two vertical plates are spaced apart, and the space between the two vertical plates is used to accommodate the second support base 201 in the locked state to improve positioning accuracy. The first support base 101 is fixed to the battery box frame by welding the flat plate. In other embodiments, it can also be fixed by bolting.

[0071] As a preferred embodiment, 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 fixes the circular arc groove provided on the fixing column 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 axis of the fixing column 205. Figure 7 As shown, a flange portion is provided on the socket 202, 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 base 201 comprises two opposing L-shaped plates and a plurality of support columns 206 mounted on the L-shaped plates. The support columns 206 have threaded sections at both ends, and sleeves 207 are sleeved on the exterior of the support columns 206. The ends of the sleeves 207 abut between the two L-shaped plates. Nuts are sleeved on the threaded sections, and the nuts abut against the L-shaped plates. The provision of sleeves 207 facilitates controlling the thickness of the second support base 201 and adjusting the gap between the first and second support bases 101, ensuring smooth insertion of the connector 102 into the socket 2021 when the first support base 101 is lowered, thereby improving positioning accuracy.

[0073] Further, if Figures 2 to 6 As shown, the L-shaped plate includes a longitudinal plate 2011 and a transverse plate 2012 connected together. The drive assembly 203 and the socket 202 are both arranged on the longitudinal plate 2011. The upper end of the longitudinal plate 2011 is also provided with an open slot 20111 for accommodating the plug-in component 102. The transverse plate 2012 is provided with a first mounting portion 20121 connected to the battery rack base 3. The second support base 201 is connected and fixed to the battery rack base 3 via the first mounting portion 20121. In this embodiment, the first mounting portion 20121 is a plurality of circular holes spaced apart on the transverse plate 2012. The second support base 201 is connected to the battery rack base 3 by bolts.

[0074] Furthermore, if Figures 2 to 4 As shown, the opening slot 20111 includes an upwardly opening tapered section 20112 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 connector 102 includes a connecting post 1021 and an inserting barrel 1022 that is sleeved on the outer side of the connecting post 1021. The width of the vertical section 20113 matches the outer diameter of the inserting barrel 1022. The provision of the tapered section 20112 enables the socket 202 to be guided into the vertical section 20113 by the tapered section 20112 when the first locking assembly 1 and the second locking assembly 2 are not aligned, thereby achieving accurate positioning when the battery box moves downward.

[0075] Preferably, if Figures 2 to 8 As shown, the drive assembly 203 includes a drive portion 2031 pivotally connected to the second support base 201, and a locking member 2032 connected to the power output end of the drive portion 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 drive portion 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 drive portion 2031 uses a hydraulic pump, and the controller controls the hydraulic pump to rotate forward or reverse to cause the locking member 2032 to abut or move away from the socket 202.

[0076] In order to improve the locking effect, such as 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] Further, if Figure 7As shown, the socket 202 further has a first rounded corner 2023, the first abutting surface 2022 being connected to the first rounded corner 2023. The locking member 2032 further has a second rounded corner 20322, the second abutting surface 20321 being connected to the second rounded corner 20322. The radius of the first rounded corner 2023 is 5 mm or 10 mm, respectively, and the radius of the second rounded corner 20322 is 10 mm or 5 mm, respectively. This arrangement ensures that the locking member 2032 and the socket 202 move smoothly and without jamming during the locking or unlocking process between 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 disposed between the two L-shaped plates. A mounting seat 209 is provided at the fixed end of the driving unit 2031. The mounting seat 209 is sleeved onto the first fixed shaft 208. A first limiting sleeve 210 is provided at each end of the mounting seat 209. The first limiting sleeve 210 abuts between the L-shaped plate and the mounting seat 209. The first limiting sleeve 210 sleeves onto the first fixed shaft 208. The provision of the first limiting sleeve 210 allows the axial position of the driving unit 2031 along the first fixed shaft 208 to be adjusted, thereby ensuring smooth movement of the locking member 2032 and the driving unit 2031.

[0079] In addition, as Figures 4 to 8 As shown, a second limiting sleeve 211 is sleeved on the outside 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. Third limiting sleeves 213 are provided on both sides of the socket 202, and the third limiting sleeves 213 abut 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 a locking effect.

[0080] The controller for the battery locking mechanism in the battery swapping system for new energy mining dump trucks in this embodiment utilizes control elements such as a PLC. Furthermore, a pressure sensor for real-time monitoring of the hydraulic system's pressure is located within the drive unit 2031 or on the hydraulic pipeline. This pressure sensor transmits data to the controller, which stops the hydraulic pump when the pressure reaches a preset safe and stable locking pressure. Based on the preset pressure range and data fed back by the pressure sensor, the controller precisely controls the hydraulic pump's operating state, thereby adjusting the hydraulic cylinder's motion and achieving precise control of the battery locking force.

[0081] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
