[0041] As described in the background section, a leaf spring mounting assembly is an elastic suspension structure made up of multiple layers of spring steel plates. It is typically installed between the axle and the frame to cushion road impacts through elastic deformation, while also bearing vehicle loads and transmitting forces and torques.
[0042] In related technologies, a leaf spring mounting assembly includes a leaf spring support and a leaf spring mounted on the leaf spring support. The leaf spring is connected to the axle, and the leaf spring support is connected to the vehicle frame via bolts and nuts.
[0043] However, as the required driving range of automobiles continues to increase, the size of automobile batteries also increases, which will encroach on the space of the vehicle frame, and in turn, encroach on the space for the installation and removal of leaf spring supports, making it difficult to disassemble the leaf spring supports.
[0044] The leaf spring mounting mechanism and automobile provided in this application include a leaf spring mounting assembly and a connector. The leaf spring mounting assembly is configured to connect to the vehicle frame. The leaf spring mounting assembly has a mounting cavity and a first mounting hole and a second mounting hole. The first mounting hole and the second mounting hole are located on two opposing cavity walls of the mounting cavity. The first mounting hole is near the outer side of the vehicle frame, and the second mounting hole is near the inner side of the vehicle frame. The connector includes a connecting part and a force-applying part. The connecting part is located in the mounting cavity and also passes through the first mounting hole and the second mounting hole. One end of the connecting part passing through the second mounting hole is threadedly connected to the leaf spring mounting assembly. The connecting part is configured to connect to the leaf spring. The force-applying part is connected to the end of the connecting part adjacent to the first mounting hole, and the force-applying part is configured to drive the connecting part to rotate relative to the leaf spring mounting assembly under the action of an external force. By rotating the force-applying part, the connector can be directly removed from the outer side of the vehicle frame, thus eliminating the need to disassemble the spring mounting assembly from the inner side of the vehicle frame and greatly improving the disassembly and assembly efficiency.
[0045] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will be described below with reference to the accompanying drawings.
[0046] Please refer to Figures 1 to 5 In a first aspect, this embodiment provides a leaf spring 10 mounting mechanism, including a leaf spring 10 mounting assembly configured to connect to the vehicle frame. The leaf spring 10 mounting assembly has a mounting cavity and a first mounting hole 111 and a second mounting hole 112. The first mounting hole 111 and the second mounting hole 112 are located on two opposing cavity walls of the mounting cavity. The first mounting hole 111 is near the outer side of the vehicle frame, and the second mounting hole 112 is near the inner side of the vehicle frame. A connecting member 200 includes a connecting portion 210 and... The force-applying part 220 and the connecting part 210 are located in the mounting cavity, and the connecting part 210 also passes through the first mounting hole 111 and the second mounting hole 112. One end of the connecting part 210 passing through the second mounting hole 112 is threadedly connected to the mounting assembly of the leaf spring 10. The connecting part 210 is configured to connect with the leaf spring 10. The force-applying part 220 is connected to one end of the connecting part 210 adjacent to the first mounting hole 111, and the force-applying part 220 is configured to drive the connecting part 210 to rotate relative to the mounting assembly of the leaf spring 10 under the action of external force.
[0047] Specifically, in this embodiment, the leaf spring 10 mounting assembly is connected to the vehicle frame. The leaf spring 10 mounting assembly is used to fix the leaf spring 10 to the vehicle frame to support the leaf spring 10, ensure that the leaf spring 10 can reliably transmit loads, and facilitate adjustment or replacement when needed.
[0048] The leaf spring 10 mounting assembly is typically installed next to the car battery. As the required driving range of vehicles continues to increase, the size of car batteries also increases accordingly. However, in existing technologies, disassembling the leaf spring 10 mounting assembly requires an operator to reach between the car battery and the assembly. Therefore, as the size of car batteries increases, it will reduce the space between the leaf spring 10 mounting assembly and the battery, making disassembly of the assembly difficult.
[0049] To address the aforementioned issues, the leaf spring 10 mounting assembly in this proposal features a mounting cavity. A first mounting hole 111 and a second mounting hole 112 are located on opposite cavity walls. The first mounting hole 111 is closer to the outer side of the frame, and the second mounting hole 112 is closer to the inner side of the frame. This design allows the connecting member 200 to be inserted into the first and second mounting holes 111 and 112, with the force-applying part 220 located on the side of the first mounting hole 111 away from the second mounting hole 112. Therefore, during disassembly, the operator can use tools or their hands to twist the force-applying part 220 and then pull the connecting member 200 outwards from the frame to complete the disassembly. Since the disassembly operation is performed on the outer side of the frame, it is unaffected by the increased size of the automotive battery. Even if the gap between the battery and the leaf spring 10 mounting assembly decreases, it will not hinder the disassembly operation, greatly improving the ease of disassembly.
[0050] The connecting part 210 passes through one end of the second mounting hole 112 and is threadedly connected to the mounting assembly of the leaf spring 10. Thus, the self-locking property of the thread can be used to prevent the connecting part 200 from loosening when subjected to vibration.
[0051] Specifically, when the connecting part 210 is inserted into the second mounting hole 112 and threadedly connected to the leaf spring 10 mounting assembly, the friction generated between the threaded pairs will form a self-locking effect, ensuring that the connecting part 200 will not gradually loosen due to bumps or vibrations during vehicle operation.
[0052] Meanwhile, by using a threaded connection, when it is necessary to disassemble the leaf spring 10 mounting assembly, the threaded connection can be released simply by rotating the force application part 220 in the opposite direction, resulting in low maintenance costs.
[0053] Please refer to Figures 1 to 5 In an optional embodiment, the circumferential outer wall of the force-applying portion 220 is non-circular in shape.
[0054] Specifically, the circumferential outer wall of the force-applying part 220 can be hexagonal, dodecagonal, or other polygonal contours. This non-circular structural feature facilitates installation and disassembly using hand tools (such as wrenches or sockets). When the operator needs to adjust the tightness of the connector 200, they simply need to engage a tool of the appropriate size on the outer circumferential surface of the force-applying part 220 to effectively transmit torque. Compared to a circular cross-section, the non-circular structure completely prevents tool slippage, ensuring reliability when the operator applies rotational torque.
[0055] Please refer to Figures 1 to 5 In an optional embodiment, the circumferential outer wall of the force-applying portion 220 is hexagonal in shape.
[0056] Specifically, in automotive repair work, commonly used standard tools such as hexagonal wrenches and sockets are designed with hexagonal interfaces. Therefore, in this embodiment, the circumferential outer wall of the force-applying part 220 is designed as a hexagonal structure, allowing repair personnel to directly use these conventional tools for operation, avoiding the use of special tools. This improves the convenience of repair and reduces maintenance costs.
[0057] In addition, the six evenly distributed planes of the hexagonal structure can form a stable contact with the tool, ensuring effective torque transmission, while also preventing tool slippage and ensuring operational safety.
[0058] Please refer to Figures 1 to 5 In an optional embodiment, the leaf spring 10 mounting assembly includes a mounting bracket 110, which has a mounting cavity, a first mounting hole 111, and a second mounting hole 112. The second mounting hole 112 is a threaded hole, and a connecting portion 210 passes through one end of the second mounting hole 112 and is threadedly connected to the mounting bracket 110.
[0059] Specifically, the leaf spring 10 is disposed within the mounting cavity, and the mounting bracket 110 is used to support the leaf spring 10. The leaf spring 10 and the mounting bracket 110 can be connected by bolts or other means that can achieve the connection, and this embodiment does not impose any restrictions on this.
[0060] In this embodiment, both the first mounting hole 111 and the second mounting hole 112 are located on the mounting bracket 110, and the second mounting hole 112 is a threaded hole. During installation, the connecting part 210 is first inserted through the first mounting hole 111 on the outside of the frame, so that it passes through the entire mounting cavity. Then, the end is screwed into the thread of the second mounting hole 112 on the inside of the frame. This allows the force on the connecting part 200 to be evenly transmitted to the entire mounting bracket 110 when the connecting part 200 bears the load of the leaf spring 10, so as to resist the vibration and loosening during vehicle operation.
[0061] Meanwhile, by making the second mounting hole 112 a threaded hole, there is no need to add an additional fixing structure to the mounting bracket 110 to fix the connector 200, thereby simplifying the overall structure and reducing manufacturing costs.
[0062] Specifically, since the connector 200 in this embodiment directly engages with the threaded second mounting hole 112, it eliminates the need for additional parts such as nuts and washers commonly found in traditional designs, reducing assembly steps and potential failure points.
[0063] In another optional embodiment, the first mounting hole 111 can also be a threaded hole, so that both ends of the connector 200 can be threaded to form a double threaded locking structure, which further enhances the fixing effect of the connector 200 and the stability of the overall structure.
[0064] Please refer to Figures 1 to 5 In an optional embodiment, the leaf spring 10 mounting assembly includes a mounting bracket 110 and a protective sleeve 120. The mounting bracket 110 has a mounting cavity, a first mounting hole 111, and a second mounting hole 112. The protective sleeve 120 is located inside the second mounting hole 112 and is fixed relative to the mounting bracket 110. The protective sleeve 120 has a threaded hole. One end of the connecting portion 210 passes through the second mounting hole 112 and is threadedly connected to the protective sleeve 120.
[0065] Specifically, in this embodiment, the leaf spring 10 mounting assembly includes a mounting bracket 110 and a protective sleeve 120. The protective sleeve 120 is disposed within the second mounting hole 112 and has a threaded hole. The connecting part 210 is threadedly connected to the protective sleeve 120 to achieve connection with the mounting bracket 110. By setting the thread within the protective sleeve 120, when the thread wears due to repeated disassembly and assembly, only the protective sleeve 120 needs to be replaced, without replacing the entire mounting bracket 110. This simplifies the maintenance process and reduces repair costs.
[0066] In this embodiment, the protective sleeve 120 and the second mounting hole 112 are connected by an interference fit. The outer diameter of the protective sleeve 120 is larger than the inner diameter of the second mounting hole 112. During assembly, the protective sleeve 120 is pressed into the second mounting hole 112 using a press or special tooling. Due to the dimensional interference fit, the protective sleeve 120 generates radial elastic deformation with the hole wall of the second mounting hole 112 after being pressed in, resulting in continuous contact pressure. This ensures that the protective sleeve 120 is firmly fixed in the second mounting hole 112 and will not loosen due to vibration or load.
[0067] Please refer to Figures 1 to 5 In an optional embodiment, one of the hole wall of the second mounting hole 112 and the circumferential outer wall of the protective sleeve 120 has a limiting protrusion 121, and the other has a limiting groove 1121, with the limiting protrusion 121 disposed within the limiting groove 1121.
[0068] Specifically, in this embodiment, the wall of the second mounting hole 112 and the circumferential outer wall of the protective sleeve 120 adopt a limiting structure with a concave-convex fit.
[0069] Specifically, in this embodiment, a limiting groove 1121 is provided on the wall of the second mounting hole 112, and a limiting protrusion 121 is provided at a corresponding position on the outer wall of the protective sleeve 120. By interlocking the limiting groove 1121 and the limiting protrusion 121, when an operator uses a tool to screw on the connector 200, the protective sleeve 120 will not rotate with the connector 200 because it is locked by the limiting protrusion 121 and the groove. This allows the connector 200 to smoothly screw into or out of the threaded hole of the protective sleeve 120 without causing the protective sleeve 120 to rotate due to the connector 200. Simultaneously, this also prevents the protective sleeve 120 from loosening due to vibration during long-term use.
[0070] In another embodiment, a limiting protrusion 121 may be provided on the wall of the second mounting hole 112, and a limiting groove 1121 may be provided at the corresponding position on the outer wall of the protective sleeve 120. Alternatively, a limiting protrusion 121 may be provided on part of the wall of the second mounting hole 112, and a limiting groove 1121 may be provided on another part of the wall. The corresponding position on the outer wall of the protective sleeve 120 may match the second mounting hole 112. This embodiment does not impose any restrictions on this.
[0071] Please refer to Figures 1 to 5 In an optional embodiment, the leaf spring 10 mounting assembly includes a mounting bracket 110 and a first locking member 130. The mounting bracket 110 has a mounting cavity, a first mounting hole 111, and a second mounting hole 112. The first locking member 130 is located on the side of the second mounting hole 112 opposite to the first mounting hole 111, and the first locking member 130 is fixed relative to the mounting bracket 110. The connecting portion 210 passes through the second mounting hole 112 and is threadedly connected to the first locking member 130.
[0072] Specifically, in this embodiment, the leaf spring 10 mounting assembly includes a mounting bracket 110 and a first locking member 130. The first locking member 130 is disposed on the side of the second mounting hole 112 opposite to the first mounting hole 111. When the connector 200 passes through the mounting cavity, the connecting part 210 of the connector 200 forms a threaded connection with the first locking member 130. This makes the threaded connection interface located on the independent first locking member 130. When the thread is worn, the first locking member 130 can be directly replaced, protecting the mounting bracket 110 from the influence of thread wear.
[0073] For example, the first locking element 130 is a nut.
[0074] In addition, in other embodiments, the first locking member 130 can be detachably connected to the mounting bracket 110. When the threads are worn due to repeated disassembly and assembly, the connection function can be restored simply by disassembling and replacing the first locking member 130, without having to replace the entire mounting bracket 110, thereby reducing maintenance costs.
[0075] Please refer to Figures 1 to 5 In an optional embodiment, the mounting bracket 110 has an anti-rotation boss that abuts against the first locking member 130 to restrict the first locking member 130 from rotating relative to the mounting bracket 110.
[0076] Specifically, in this embodiment, the mounting bracket 110 is provided with an anti-rotation boss, which abuts against the side of the first locking member 130. Thus, when the connector 200 is screwed into the first locking member 130, the anti-rotation boss will abut against the first locking member 130, preventing it from rotating with the connector 200. This allows the operator to install or remove the connector 200 without using additional tools to restrict the rotation of the first locking member 130, greatly improving the convenience of installation and removal.
[0077] Specifically, the first locking member 130 is provided with an anti-rotation groove that engages with the anti-rotation boss. During assembly, the operator first aligns the first locking member 130 with the mounting bracket 110, so that the anti-rotation boss is embedded in the anti-rotation groove, forming a double limit in both the axial and circumferential directions. At this time, since the car battery has not yet been installed, there is ample operating space, making it easy to adjust the position of the first locking member 130 and ensure accurate engagement between the anti-rotation boss and the anti-rotation groove. Simultaneously, as the connecting member 200 is continuously screwed in, its force-applying part 220 presses against one side of the mounting bracket 110, firmly pressing the first locking member 130 onto the mounting bracket 110. At this point, the engagement between the anti-rotation boss and the anti-rotation groove further prevents the first locking member 130 from rotating, ensuring that the connecting member 200 can be tightened smoothly without causing assembly difficulties due to the first locking member 130 rotating.
[0078] Please refer to Figures 1 to 5 In an optional embodiment, the end of the connecting portion 210 that passes through the first mounting hole 111 has a first recess 211, which surrounds at least a portion of the connecting portion 210 circumferentially; the wall of the first mounting hole 111 has a second recess 1111, which, together with the first recess 211, forms a mounting space; the leaf spring 10 mounting mechanism further includes a limiting member 300 and a second locking member 400, the limiting member 300 passing through the mounting space and the end of the limiting member 300 extending outside the mounting space; the second locking member 400 is detachably connected to the end of the limiting member 300.
[0079] Specifically, in this embodiment, the end of the connecting part 210 that passes through the first mounting hole 111 is machined with an annular first recess 211, and the corresponding position of the hole wall of the first mounting hole 111 is provided with an annular second recess 1111. When the connecting part 210 is inserted into place, the two recesses align to form an annular mounting space. The limiting member 300 is radially inserted into the mounting space from the connecting part 200, with both ends extending out of the mounting space. The second locking member 400 is connected to the extended ends of the limiting member 300. This constrains the connecting part 210 in both the axial and radial directions, preventing the connecting part 200 from loosening or rotating due to bumps when the vehicle is in motion.
[0080] In an optional embodiment, the second locking member 400 may be a lock nut. The lock nut is tightened onto the threaded end of the limiting member 300, and the locking force of the nut securely fixes the limiting member 300, thus preventing the limiting member 300 from falling off due to vibration and further ensuring the stability of the connection 210.
[0081] In another alternative embodiment, the second locking member 400 may be a cotter pin. The cotter pin is pried open after passing through the pin hole at the end of the limiting member 300, thereby fixing the limiting member 300 by this mechanical locking method. This ensures that the connection structure can maintain a reliable connection under long-term vibration conditions, while also facilitating disassembly and maintenance.
[0082] Secondly, this embodiment provides an automobile, including a frame, a leaf spring 10, and a leaf spring 10 mounting mechanism as described in any of the first aspects, wherein the leaf spring 10 mounting assembly in the leaf spring 10 mounting mechanism is connected to the frame, and the connecting member 200 in the leaf spring 10 mounting mechanism is connected to the leaf spring 10.
[0083] The mounting mechanism for the leaf spring 10 has been described in the above embodiments and will not be repeated here.
