Description

Technical Field

[0001] This application relates to the field of metal brackets, and in particular to a shock-absorbing metal bracket. Background Technology

[0002] In the fields of mechanical manufacturing and electrical equipment installation, metal brackets are crucial as fundamental support and fixing components. With continuous technological advancements and significant increases in the integration of electrical equipment, the functional and performance requirements for metal brackets are becoming increasingly diverse. Metal brackets must not only provide sufficient support strength for components such as wire harnesses and aluminum busbars, but also ensure ease of installation, good vibration damping performance, and adaptability to different spatial environments. A well-designed metal bracket can significantly improve equipment stability and reliability, reduce maintenance costs, and ensure the safe and stable operation of electrical systems. To address the issue of fixing wire harnesses or aluminum busbars with metal brackets, several methods exist for fixing and damping related wire harnesses. One method consists of a metal bracket, a rubber component, and cable ties. First, the middle of the metal bracket is bent to form a placement groove. Through holes are pre-drilled in the rubber component, allowing the wire harness or aluminum busbar to pass through the through holes and be covered by the rubber component. Then, the rubber component is placed in the placement groove of the metal bracket. Finally, cable ties are used to secure the rubber component, which covers the wire harness or aluminum busbar, to the metal bracket. Another method uses clips, which are attached to a metal bracket via elastic bands. The elasticity of the bands secures the rubber component covering the wire harness or aluminum busbar to the metal bracket. These methods can meet basic fixing requirements in simple installation scenarios, and the rubber component provides some cushioning and shock absorption for the wire harness or aluminum busbar. However, existing fixing and shock-absorbing devices have significant drawbacks. Firstly, their support strength is low, the assembly process is complex, and the bracket is prone to breakage under prolonged external force or vibration. Furthermore, installation requires multiple steps, including wire harness threading, rubber component placement, and cable tie binding, increasing installation time and labor costs, and increasing the risk of errors that affect installation quality. Secondly, existing fixing devices are bulky, making effective installation difficult in confined spaces, whether using rubber components with cable ties or clips, failing to meet practical application requirements. Utility Model Content

[0003] To meet the design requirements of miniaturization and improve the structural strength and installation convenience of existing wire harness vibration damping and fixing devices, this application provides a vibration damping metal bracket.

[0004] This application provides a shock-absorbing metal bracket, including a first metal frame, a second metal frame, and fasteners. The first or second metal frame is detachably connected to an external workpiece. A first elastic portion is provided in the middle of the first metal frame; a second elastic portion is provided in the middle of the second metal frame. The first and second metal frames are detachably connected via the fasteners. The first and second elastic portions enclose a first receiving cavity for wire harness passage. By adopting the above technical solution, the first or second metal frame is detachably connected to the external workpiece, allowing the metal bracket to be flexibly installed and disassembled, facilitating maintenance and replacement. The first elastic portion is provided in the middle of the first metal frame, and the second elastic portion is provided in the middle of the second metal frame, with the first and second elastic portions enclosing a first receiving cavity for wire harness passage. The elastic parts are elastic. When the wire harness is inserted into the first receiving cavity, the two elastic parts surround the wire harness, providing cushioning and shock absorption, reducing damage caused by vibration. The two metal frames provide support, improving the overall structural strength. Even under long-term external force or vibration, the metal frames will not break, extending the service life of the wire harness. Simultaneously, the first and second metal frames are detachably connected via fasteners. This detachable connection simplifies the assembly process, avoiding the complex steps of sequentially inserting the wire harness, placing rubber parts, and securing with cable ties, reducing installation time and labor costs, minimizing the possibility of operational errors, and improving installation quality. Moreover, compared to existing fixing devices, this shock-absorbing metal bracket structure is more compact, enabling effective installation even in space-constrained areas, meeting practical application needs. Preferably, the first and second elastic parts enclose a second receiving cavity for the wire harness to be inserted. By adopting the above technical solution, the first elastic part and the second elastic part are enclosed together. Due to their structural and positional relationship, a space for wire harnesses to pass through, namely the second receiving cavity, is naturally formed. This provides a new path and receiving space for the wire harnesses, meeting the needs of arranging more wire harnesses. Preferably, the first elastic part is provided with a first groove, and a first protrusion is formed on one side of the first groove. The second elastic part is provided with a second groove, and a second protrusion is formed on one side of the second groove. The first protrusion blocks the opening of the second groove to form the first receiving cavity, and the second protrusion blocks the opening of the first groove to form the second receiving cavity.By adopting the above technical solution, the first elastic part is provided with a first groove and a first protrusion on one side, and the second elastic part is provided with a second groove and a second protrusion on one side. Since the first protrusion can block the opening of the second groove, the two enclose a relatively closed space, which forms a first receiving cavity for wire harnesses to pass through. Similarly, the second protrusion blocks the opening of the first groove, also enclosing a relatively closed space, thus forming a second receiving cavity for wire harnesses to pass through. In this way, two independent passing spaces are provided for the wire harnesses, which facilitates the classification, passing through, and management of different wire harnesses. Preferably, the first groove is a U-shaped groove and the second groove is an L-shaped groove. By adopting the above technical solution, the first groove is configured as a U-shaped groove and the second groove as an L-shaped groove. The U-shaped groove has two parallel sides and a bottom, providing a relatively stable and spacious support space for the wire harness. The shape of the L-shaped groove can cooperate with the U-shaped groove. When the first protrusion blocks the opening of the second groove to form a first receiving cavity, and the second protrusion blocks the opening of the first groove to form a second receiving cavity, this special groove combination makes the structure of the two receiving cavities more reasonable and compact. This ensures effective accommodation of the wire harness and achieves a good layout within a limited space, improving the space utilization efficiency of the metal bracket and enhancing the fixation and protection effect of the wire harness. Preferably, the first receiving cavity and the second receiving cavity are staggered in the vertical direction. By adopting the above technical solution, the first and second receiving cavities are staggered vertically, avoiding overlap in the same vertical position and reducing the space occupied by the shock-absorbing metal bracket in the vertical direction. This allows the metal bracket to better adapt to installation in places with limited space. Simultaneously, this staggered arrangement allows the wire harnesses to be distributed more orderly in different receiving cavities during installation, reducing the possibility of mutual interference and tangling between wire harnesses, and improving the rationality and stability of the wire harness arrangement. Preferably, the first and second receiving cavities are of equal size. By adopting the above technical solution, the equal size of the first and second receiving cavities provides uniform space for wire harnesses at different positions when accommodating them, achieving a good layout within limited space and improving the space utilization efficiency of the metal bracket. Preferably, both the first and second metal frames are bent to form U-shaped mounting grooves. By adopting the above technical solution, both the first and second metal frames are bent to form U-shaped mounting grooves. The U-shaped structure has better stability and support, providing higher support strength for the shock-absorbing metal bracket. Compared with existing fixing devices with lower support strength, this structure can better withstand external forces and vibrations, reducing the risk of bracket breakage. Preferably, the first elastic part is integrally vulcanized in the mounting groove of the first metal frame, and the second elastic part is integrally vulcanized in the mounting groove of the second metal frame.By adopting the above technical solution, since the first elastic part is integrally vulcanized in the mounting groove of the first metal frame and the second elastic part is integrally vulcanized in the mounting groove of the second metal frame, the integral vulcanization method tightly integrates the elastic part and the metal frame into a whole. This integration method enhances the stability of the structure. When supporting the wire harness, it can provide more reliable support, reduce swaying and displacement caused by vibration or external force, and thus improve the support strength and vibration damping performance of the entire shock-absorbing metal bracket. At the same time, the integral vulcanization process reduces assembly steps, eliminating the need to complete multiple operations sequentially as in the traditional method, reducing installation time and labor costs, reducing the possibility of operational errors, and improving installation quality. Preferably, the first metal frame extends horizontally outward on both sides to form a first fixing part, and the first fixing part is provided with a first screw hole. The second metal frame extends horizontally outward on both sides to form a second fixing part, and the second fixing part is provided with a second screw hole. The first screw hole is fastened to the second screw hole by the fastener. By adopting the above technical solution, the first metal frame extends horizontally outward from both sides to form a first fixing part and is provided with a first screw hole, and the second metal frame extends horizontally outward from both sides to form a second fixing part and is provided with a second screw hole. Since the fasteners can pass through the first screw hole and the second screw hole, the first metal frame and the second metal frame can be stably connected together, ensuring the stability of the overall structure of the shock-absorbing metal bracket. Moreover, this connection method is convenient for disassembly and installation, improving the ease of operation. Preferably, the first metal frame is detachably connected to an external workpiece, and the first fixing part extends toward the bottom of the mounting groove of the second metal frame to form a mounting part, the mounting part being provided with mounting holes for connecting the external workpiece. By adopting the above technical solution, the first fixing part of the first metal frame extends toward the bottom of the mounting groove of the second metal frame to form a mounting part, and the mounting part is provided with mounting holes. Since the mounting holes are used to connect external workpieces, the first metal frame can be detachably connected to the external workpieces. This structural design makes the shock-absorbing metal bracket more flexible in installation. The first metal frame can be installed on different external workpieces according to actual needs, and it can be easily removed from the external workpieces when replacement or maintenance is required, thus improving the operability and practicality of the bracket.

[0005] In summary, this application includes at least one of the following beneficial technical effects: 1. Since the first metal frame and the second metal frame are detachably connected by fasteners, and the first elastic part and the second elastic part form a cavity for the wire harness to be threaded through, it is not necessary to complete multiple operation steps such as threading the wire harness, placing the rubber parts and binding the cable ties in sequence as in the prior art. Therefore, the installation steps are simplified, thereby reducing the installation time and labor costs, while reducing the possibility of operational errors and improving the installation quality. 2. Because the first elastic part is integrally vulcanized in the mounting groove of the first metal frame and the second elastic part is integrally vulcanized in the mounting groove of the second metal frame, this integral vulcanization method enhances the connection strength between the elastic part and the metal frame, making the overall structure of the metal bracket more stable. Therefore, it improves the support strength of the metal bracket and can prevent it from breaking under long-term external force or vibration. 3. The shock-absorbing metal bracket integrates the first and second elastic parts into the corresponding metal frame mounting grooves and rationally sets up two receiving cavities, making the overall structure compact. This solves the problems of existing fixing devices being large in size and difficult to install in space-constrained areas, and is applicable to the partitioned fixing of various types of wire harnesses.

[0008] The following is in conjunction with the appendix Figure 1-2 This application will be described in further detail.

[0009] This application provides an embodiment of a shock-absorbing metal bracket, referring to... Figure 1 and Figure 2 The assembly includes a first metal frame 1, a second metal frame 2, and fasteners 3. The first metal frame 1 has a first elastic part 4 in the middle, and the second metal frame 2 has a second elastic part 5 in the middle. In this embodiment, the first metal frame 1 is detachably connected to an external workpiece. The first metal frame 1 and the second metal frame 2 are fastened together by fasteners 3. When the first metal frame 1 and the second metal frame 2 are assembled by fasteners 3, the first elastic part 4 and the second elastic part 5 enclose and form a first receiving cavity 6 and a second receiving cavity 7 for wire harnesses to pass through, so that aluminum busbars and cables can be placed in the first receiving cavity 6 and the second receiving cavity 7 respectively.

[0010] In this embodiment, the first elastic part 4 and the second elastic part 5 provide shock-absorbing and buffering support for the aluminum busbar and cables, achieving the effect of convenient installation of wire harnesses and shock absorption function. The first metal frame 1 and the second metal frame 2 are fastened together by two fasteners 3, which adopts a two-point installation support method, enabling stable installation in narrow spaces. Furthermore, the detachable connection of the first metal frame 1 and the second metal frame 2 also simplifies the installation process.

[0011] Specifically, the first metal frame 1 is bent in the middle to form a U-shaped mounting groove, and the two sides of the first metal frame 1 extend horizontally outward to form a first fixing part 11. The first elastic part 4 is integrally vulcanized in the U-shaped mounting groove formed by bending the first metal frame 1; the second metal frame 2 is bent in the middle to form a U-shaped mounting groove, and the two sides of the second metal frame 2 extend horizontally outward to form a second fixing part 21. The first elastic part 4 is integrally vulcanized in the U-shaped mounting groove formed by bending the first metal frame 1; the second elastic part 5 is integrally vulcanized in the U-shaped mounting groove formed by bending the second metal frame 2.

[0012] Specifically, the first fixing part 11 is provided with a first screw hole 111, and the second fixing part 21 is provided with a second screw hole 211. The second screw hole 211 corresponds to the first screw hole 111 of the first fixing part 11. The first screw hole 111 is used to mate with the second screw hole 211 on the second metal frame 2, and the connection between the first metal frame 1 and the second metal frame 2 is achieved by fastener 3. The shapes of the first fixing part 11 and the second fixing part 21 are relatively regular, which facilitates processing and installation. This connection method is simple and reliable, and facilitates installation and disassembly. When it is necessary to maintain or replace the wire harness, the bracket can be easily opened. By tightening or loosening the fastener 3, the connection or separation of the first metal frame 1 and the second metal frame 2 can be easily achieved. The fastener 3 is a bolt, screw, screw, etc.

[0013] The first metal frame 1 is detachably connected to an external workpiece. A first fixing part 11 extends towards the bottom of the mounting groove of the second metal frame 2 to form a mounting part 12. The mounting part 12 is provided with mounting holes 121 for connecting to the external workpiece. The mounting part 12 allows the first metal frame 1 to be stably connected to the external workpiece, further improving the overall stability of the support. The first metal frame 1 can be securely fixed to the external workpiece via the mounting holes 121 and corresponding connectors, such as bolts.

[0014] In this embodiment, both the first elastic part 4 and the second elastic part 5 are made of rubber. Integrated vulcanization refers to the process of vulcanizing the rubber-made first elastic part 4 and the second elastic part 5 with the first metal frame 1 and the second metal frame 2 under specific process conditions in an environment with high temperature and high pressure, so that the two are tightly bonded into a single unit. This integrated vulcanization method results in a tight, reliable bond, preventing loosening or separation between the elastic part and the metal frame during long-term use. Rubber has good elasticity and shock absorption properties, effectively buffering the vibrations experienced by the wire harness. When the wire harness is subjected to external vibrations, the rubber material undergoes elastic deformation, absorbing the vibration energy and converting it into its own internal energy, thereby reducing the vibration energy transmitted to the wire harness and playing a shock-absorbing role. Of course, other embodiments can also use other elastic materials such as silicone to replace rubber. Silicone also has good elasticity and stability, meeting the requirements for shock absorption.

[0015] Specifically, the first elastic part 4 is provided with a first groove 41, and a first protrusion 42 is formed on one side of the first groove 41. The second elastic part 5 is provided with a second groove 51, and a second protrusion 52 is formed on one side of the second groove 51. Both the first groove 41 and the second groove 51 are U-shaped grooves. The structure of the U-shaped groove can better accommodate the wire harness and provide a stable placement space for the wire harness. The side walls of the U-shaped groove can limit the wire harness and prevent the wire harness from swaying left and right during vibration. The second groove 51 is an L-shaped groove. The L-shaped groove cooperates with the U-shaped groove of the first elastic part 4 to better enclose and form a receiving cavity.

[0016] The combination logic of the first elastic part 4 and the second elastic part 5 is as follows: the first protrusion 42 blocks the opening of the second groove 51 to form the first receiving cavity 6, and the second protrusion 52 blocks the opening of the first groove 41 to form the second receiving cavity 7. The first receiving cavity 6 and the second receiving cavity 7 are vertically offset and of equal size. This design allows the two receiving cavities to accommodate different wire harnesses, improving the efficiency of the bracket. The offset arrangement also avoids mutual interference between the wire harnesses. Furthermore, due to the elasticity of the first elastic part 4 and the second elastic part 5, when the wire harness is subjected to vibration, the elastic parts can absorb and buffer the vibration energy, protecting the wire harness from damage. Specifically, when vibration is transmitted to the wire harness, the first elastic part 4 and the second elastic part 5 simultaneously undergo elastic deformation, dispersing and absorbing the vibration energy, reducing the impact force on the wire harness.

[0017] The implementation principle of this embodiment is as follows: The shock-absorbing metal bracket of this embodiment provides good shock absorption protection for the wire harness through the integrally vulcanized first elastic part 4 and second elastic part 5, reducing the risk of damage to the wire harness due to vibration. The integral vulcanization structure ensures a tight connection between the elastic part and the metal frame, allowing the elastic part to better perform its shock absorption function. The first metal frame 1 and the second metal frame 2 are detachably connected by fasteners 3, and the first metal frame 1 is also detachably connected to the external workpiece, making the installation and disassembly of the bracket very convenient, greatly improving installation efficiency and reducing installation costs. At the same time, the design of the first receiving cavity 6 and the second receiving cavity 7 can accommodate multiple wire harnesses simultaneously, improving the utilization efficiency of the bracket. Significant improvements and enhancements have been made in terms of support strength, installation convenience, and shock absorption performance, better meeting the needs of practical applications.

[0018] Example 2 The difference between this embodiment and the previous embodiment is that the way the first elastic part 4 and the second elastic part 5 enclose to form the receiving cavity can be designed differently. For example, the first elastic part 4 and the second elastic part 5 can use grooves and protrusions of other shapes to form the receiving cavity, and are not necessarily limited to a combination of U-shaped grooves and L-shaped grooves. It can be designed that two semi-circular grooves cooperate with each other to form a circular receiving cavity.

[0019] The implementation principle of this embodiment is as follows: by changing the shape of the groove and the protrusion of the first elastic part 4 and the second elastic part 5, accommodating cavities of different shapes can be formed. This allows for a more optimized design based on the actual shape of the wire harness, improving the adaptability of the bracket to wire harnesses of different shapes, thereby better protecting the wire harness, and also improving the versatility of the bracket to a certain extent.

[0020] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
