Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of buffer components, and more particularly to buffer components and power systems. Background Technology
[0002] With the rapid development of new energy vehicles and intelligent vehicles, higher demands are being placed on the functionality, safety, and intelligence of vehicle electrical systems. As a core component of the vehicle's electrical architecture, the power distribution system is responsible for the efficient distribution of the vehicle's electrical energy and the power supply management of various electrical devices, playing a crucial role in ensuring the stable operation of all functional units and driving safety. In existing technologies, vehicle power distribution systems typically employ a rigid installation method, directly fixing components such as the distribution box to the vehicle body structure using metal brackets or fasteners. While this traditional installation method is simple in structure and low in cost, it has significant technical shortcomings in practical applications.
[0003] First, vehicles frequently encounter complex road conditions during operation, and vibrations from the road surface and occasional mechanical shocks inevitably transmit to various components of the vehicle body. Traditional rigidly installed electrical distribution systems are prone to problems such as loosening of mounting points, loosening of fasteners, and relative displacement between the electrical distribution system and the vehicle under long-term vibration and impact. This can further lead to poor contact of connectors, electrical connection failures, and even affect the normal operation of the system. Furthermore, the accumulation of mechanical stress can damage the outer casing or internal circuit boards of the electrical distribution system, reducing the overall reliability and lifespan of the system.
[0004] Secondly, the installation process of existing power distribution systems is generally cumbersome, requiring precise alignment and multiple tightening operations, which increases the difficulty of assembly and the intensity of manual labor, and is also detrimental to later maintenance and replacement. As some vehicles enhance their intelligence and high-voltage power distribution capabilities, they place higher demands on the size, weight, and protection level of the power distribution system itself. Traditional rigid installation methods are insufficient to meet the vibration and shock resistance requirements of high-performance electrical systems, easily becoming a weak link in vehicle safety management.
[0005] To address the aforementioned issues, some technical solutions attempt to add flexible pads, rubber gaskets, and other cushioning materials between the power distribution system and the vehicle body to absorb and mitigate some vibrations and impacts. However, these simple cushioning measures have limited structural design and performance, and suffer from drawbacks such as insecure installation and susceptibility to aging and failure, making it difficult to maintain continuous effectiveness under high-intensity operating conditions. Therefore, how to improve the vibration and impact resistance of the power distribution system while ensuring efficient and safe power supply, simplifying the assembly process, and enhancing overall reliability and service life has become a pressing technical challenge in the field of vehicle electrical systems.

[0017] Meanwhile, the inner sleeve is equipped with fixing holes, through which the first and second through holes can be passed in sequence, allowing fasteners to pass through and connect to the vehicle, thus achieving reliable locking of the power distribution system.

[0026] The embodiments of this utility model will be described in detail below with reference to the accompanying drawings, clearly and comprehensively demonstrating the technical solution. It should be noted that the listed embodiments are only a part of this utility model, and not all possible implementations. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.
[0027] Please see Figures 1 to 3 As shown, Figure 1 This is a schematic diagram of the structure of the power distribution system 200 and the buffer component 100 provided in this embodiment of the present invention. Figure 2 This is provided by the embodiment of the present utility model. Figure 1 A magnified view of a portion of region A in the middle. Figure 3 This is a schematic diagram of the structure of a buffer component 100 provided in an embodiment of the present invention.
[0028] This utility model relates to a vehicle comprising: a power distribution system 200, a buffer assembly 100, and fasteners 300. The power distribution system 200 is locked within the vehicle via the buffer assembly 100 and the fasteners 300. The power distribution system 200 is responsible for the vehicle's power distribution, safety protection, and intelligent management. Its core function is to achieve efficient energy transmission through high-voltage power distribution and ensure the stable operation of all vehicle systems. This technical solution, by installing the power distribution system 200 within the vehicle and using the buffer assembly 100 to lock the power distribution system 200 within the vehicle structure, provides an effective solution to the technical problem that traditional power distribution systems 200 are susceptible to loosening, poor contact, and even malfunctions during installation due to vehicle vibration and impact. The buffer assembly 100 can absorb and mitigate vibrations and impacts generated during vehicle operation, thereby significantly improving the installation stability and reliability of the power distribution system 200 and preventing displacement or damage due to mechanical stress.
[0029] Through the above technical solutions, the power distribution system 200 can continuously and stably complete the efficient distribution and safety protection of the vehicle's electrical energy, ensuring the normal operation of each electrical unit in the vehicle, and improving the overall vehicle's operational safety and the level of intelligent system management. Furthermore, the high-voltage power distribution capability of the power distribution system 200, combined with the protective function of the buffer component 100, improves energy transmission efficiency, extends the service life of both the power distribution system 200 and the buffer component 100, reduces maintenance frequency, and further enhances the overall vehicle performance and user experience.
[0030] Therefore, the technical solution described in this embodiment effectively solves the problem of insufficient reliability caused by the susceptibility of the power distribution system 200 to vibration through the collaborative design of the power distribution system 200 and the buffer component 100, and achieves the technical effects of efficient and safe power distribution and stable system operation.
[0031] The buffer assembly 100 includes a first buffer member 10, a second buffer member 20, and an inner sleeve 30. The first buffer member 10 has a first through hole 18, and the second buffer member 20 has a second through hole 21. The second buffer member 20 is connected to the first buffer member 10, and the first through hole 18 and the second through hole 21 communicate with each other. A clamping groove 101 is formed between the outer peripheral surfaces of the first buffer member 10 and the second buffer member 20, spaced apart. The clamping groove 101 is used to clamp the power distribution system 200. The first buffer member 10 and the second buffer member 20 are separated, facilitating the insertion of the power distribution system 200 into the clamping groove 101 at the desired fixing position. The inner sleeve 30 has a fixing hole 35, through which the first through hole 18 and the second through hole 21 pass sequentially. The fixing hole 35 allows a fastener 300 to pass through and connect to the vehicle, thereby locking the power distribution system 200 into the vehicle. The inner sleeve 30 can hold the fixing member in place, thus preventing the fixing member from squeezing the second buffer member 20.
[0032] Specifically, the buffer assembly 100 consists of a first buffer member 10, a second buffer member 20, and an inner sleeve 30. The first buffer member 10 and the second buffer member 20 are respectively provided with a first through hole 18 and a second through hole 21, and form a clamping groove 101 on their outer peripheral surfaces through a spaced fit, for clamping the power distribution system 200. This structure allows the first buffer member 10 and the second buffer member 20 to be separated, enabling the power distribution system 200 to be easily inserted into the clamping groove 101 for positioning, greatly improving the convenience and accuracy of installation, reducing the difficulty of manual operation, and increasing assembly efficiency.
[0033] Meanwhile, the inner sleeve 30 is provided with a fixing hole 35, through which the first through hole 18 and the second through hole 21 can be passed in sequence, allowing the fastener 300 to pass through and connect to the vehicle, thereby achieving reliable locking of the power distribution system 200. It is worth mentioning that the inner sleeve 30 can hold the fixing component, effectively preventing the fastener 300 from squeezing and damaging the second buffer component 20 during the locking process, thus ensuring the structural integrity and buffering performance of the buffer assembly 100 and extending the service life of the components.
[0034] The above technical solutions solve the problems of easy damage, unstable fixing and complicated installation of the power distribution system 200 during installation, realize the rapid and reliable installation of the power distribution system 200, and effectively improve its vibration and shock resistance, further ensuring the safety and stability of the vehicle power distribution system.
[0035] The first buffer 10 includes a main portion 12 and a first extension 14. The first extension 14 is disposed on the side of the main portion 12 facing the second buffer 20. The first extension 14 and the second buffer 20 support each other, and the main portion 12 and the second buffer 20 form a clamping groove 101 at intervals.
[0036] This technical solution addresses the technical problems of existing buffer components 100 when clamping power distribution systems 200, such as unstable clamping, insufficient buffering effect, or the single structure of the clamping groove 101 making it difficult to adapt to power distribution systems 200 of different shapes, by setting a main part 12 and a first extension part 14 on the first buffer 10.
[0037] Specifically, the first extension 14 is disposed on the side of the main portion 12 facing the second buffer member 20. The first extension 14 and the second buffer member 20 form a top-holding engagement, thereby enhancing the structural stability between the first buffer member 10 and the second buffer member 20, and giving the clamping groove 101 better adaptive clamping force. The main portion 12 and the second buffer member 20 are spaced apart to form the clamping groove 101, providing a stable installation space for the power distribution system 200. This structure not only simplifies the clamping operation, allowing the power distribution system 200 to be easily and quickly inserted into the clamping groove 101 for positioning, but also effectively prevents the power distribution system 200 from loosening or shifting due to vibration or impact during vehicle operation.
[0038] In addition, the supporting action of the first extension 14 and the second buffer 20 helps to disperse and absorb the mechanical stress applied by the outside, improve the overall impact and shock resistance of the buffer assembly 100, and further protect the power distribution system 200 from damage.
[0039] In summary, this technical solution achieves efficient clamping and buffering of the power distribution system 200 through the reasonable structural design of the main part 12 and the first extension part 14 of the first buffer 10, solving the problems of weak clamping and limited buffering capacity of the traditional clamping groove 101 structure, thereby improving the installation stability and reliability of the power distribution system 200.
[0040] The second buffer member 20 has a limiting groove 23, and the first extension 14 is inserted into the limiting groove 23 to support the second buffer member 20. This technical solution provides an effective solution to the technical problems of inaccurate positioning, easy loosening of structure, and displacement of buffer member in the existing buffer assembly 100 during the clamping of the power distribution system 200 by setting a limiting groove 23 on the second buffer member 20 and inserting the first extension 14 into the limiting groove 23 to support the second buffer member 20.
[0041] Specifically, the limiting groove 23 provided in the second buffer member 20 can accurately limit the insertion position of the first extension 14, so that the first buffer member 10 and the second buffer member 20 are precisely positioned. The first extension 14 is inserted into the limiting groove 23 and abuts against the second buffer member 20, which not only effectively prevents relative slippage or misalignment between the first buffer member 10 and the second buffer member 20, but also further improves the stability of the overall structure. In this way, the structure of the clamping groove 101 is more stable, and the power distribution system 200 can be more reliably clamped after being inserted into the clamping groove 101, avoiding the risk of the power distribution system 200 loosening or falling off due to component displacement.
[0042] In addition, the top-holding cooperation between the limiting groove 23 and the first extension 14 can disperse and absorb the impact of external forces, improve the vibration resistance and impact resistance of the buffer assembly 100, and thus further protect the power distribution system 200 from damage during vehicle operation.
[0043] In summary, this technical solution, through the cooperation of the limiting groove 23 and the first extension 14, effectively solves the problems of inaccurate positioning and easy loosening of the buffer assembly 100 in practical applications, realizes the precise positioning and stable clamping of the power distribution system 200, and improves the overall buffering effect and reliability of use.
[0044] The distance between the main part 12 and the second buffer member 20 gradually decreases from the opening of the clamping groove 101 to its interior, presenting a trumpet shape. This technical solution addresses the technical problems of existing buffer components 100 when clamping the power distribution system 200, such as insertion difficulties, inaccurate positioning, and insufficient clamping stability. It proposes a structural design in which the distance between the main part 12 and the second buffer member 20 gradually decreases from the opening of the clamping groove 101 to its interior, presenting a trumpet shape.
[0045] Specifically, by increasing the spacing at the entrance of the clamping slot 101 to form a flared structure, the power distribution system 200 can be inserted into the clamping slot 101 more smoothly, reducing the insertion force and solving the problem of difficulty in inserting the power distribution system 200 and easy jamming caused by the narrow entrance of the traditional clamping slot 101. At the same time, the gradually decreasing internal spacing of the clamping slot 101 allows the power distribution system 200 to automatically orient itself and gradually conform to the wall of the clamping slot 101 during the insertion process, achieving automatic guidance and centering positioning, and improving the clamping accuracy.
[0046] In addition, the flared structure, combined with the gradually tightening clamping space, can generate a progressive clamping force on the power distribution system 200, avoiding the phenomenon of excessive local force or weak clamping caused by uneven distribution of clamping force, effectively improving the stability and reliability of clamping, and preventing the power distribution system 200 from loosening or falling off during use.
[0047] In summary, this technical solution, through the flared structure design of the spacing between the main part 12 and the second buffer 20, solves the problems of inconvenient insertion, inaccurate positioning, and weak clamping in the prior art, and realizes smooth insertion, accurate positioning, and firm clamping of the power distribution system 200, thereby improving the installation convenience and reliability of the buffer assembly 100.
[0048] The buffer assembly 100 also includes an outer sleeve 40, which is disposed in the clamping groove 101 and contacts the main part 12, and surrounds the first extension 14. The power distribution system 200 contacts the main part 12 through the outer sleeve 40, thereby preventing the main part 12 from being worn. This technical solution addresses the technical problem that in the actual use of the existing buffer assembly 100, the power distribution system 200 directly contacts the main part 12, which easily leads to wear of the main part 12 due to repeated insertion and removal and friction, thus affecting the clamping stability and component life. The solution proposes a structural design that adds an outer sleeve 40 in the clamping groove 101, and makes the outer sleeve 40 contact the main part 12 and surround the first extension 14.
[0049] Specifically, by providing an outer sleeve 40 within the clamping groove 101, the power distribution system 200 first contacts the outer sleeve 40 upon insertion into the clamping groove 101, rather than directly rubbing against the main part 12. The outer sleeve 40 surrounds the first extension 14 and fits snugly against the main part 12, acting as a buffer and protector, effectively distributing the frictional force generated during the insertion and removal of the power distribution system 200, thereby preventing damage to the surface of the main part 12 due to long-term use. In this way, the main part 12 can maintain its original structural strength and surface integrity for a longer period, extending the service life of the buffer assembly 100.
[0050] In addition, with the outer jacket 40 installed, as an easily replaceable consumable part, when the performance of the outer jacket 40 is affected by wear, the outer jacket 40 can be replaced separately without replacing the entire cushioning assembly 100, which reduces maintenance costs and improves the convenience and economy of use.
[0051] In summary, this technical solution, by setting an outer sleeve 40 in the clamping groove 101 that contacts the main part 12 and surrounds the first extension part 14, effectively protects the main part 12 during the insertion and removal of the power distribution system 200, solves the problem of easy wear of the main part 12, thereby improving the durability and maintainability of the buffer assembly 100 and achieving a better buffer protection effect.
[0052] The outer casing 40 includes a first part 41 and a second part 43 that are interconnected. The first part 41 is connected to the main part 12, and the second part 43 contacts the first extension 14, providing protection for the first extension 14. Specifically, by designing the outer casing 40 to consist of the first part 41 and the second part 43, with the first part 41 firmly connected to the main part 12, the positioning stability of the outer casing 40 in the clamping groove 101 is ensured. The second part 43 directly contacts the first extension 14, so that when the power distribution system 200 is inserted or removed, the power distribution system 200 does not directly rub against the first extension 14, but instead contacts the second part 43. In this way, the second part 43 can effectively provide isolation and protection for the first extension 14, preventing the first extension 14 from wearing, deforming, or being damaged due to frequent friction.
[0053] Furthermore, the second part 43, as a component of the outer casing 40, can have its material and structure optimized according to actual needs, giving it better wear resistance and cushioning performance, further enhancing the protection of the first extension 14. When the second part 43 wears out due to long-term use, only the outer casing 40 needs to be replaced without replacing the entire cushioning assembly 100, reducing maintenance costs and improving the efficiency and economy of the component.
[0054] The first buffer 10 also includes a second extension 16, which is connected to the first extension 14. A second part 43 is inserted into the limiting groove 23 and supports the second extension 16. This technical solution addresses the technical problems of existing buffer components 100 in practical applications, such as unstable position of the first extension 14, stress concentration leading to structural deformation, wear, or even failure, due to the lack of effective support between the first extension 14 and the limiting groove 23. The solution proposes a design where the first buffer 10 also includes a second extension 16, which is connected to the first extension 14 and supported by the second part 43 inserted into the limiting groove 23.
[0055] Specifically, by providing a second extension 16 on the first buffer member 10, the first extension 14 and the second extension 16 form an integral connection structure, enhancing the overall mechanical strength and rigidity. Based on this, the second part 43 is inserted into the limiting groove 23 and supports the second extension 16. This provides stable support for the second extension 16 within the limiting groove 23, preventing it from shaking or shifting during insertion, removal, or under stress. Furthermore, the supporting action of the second part 43 effectively disperses the external force borne by the first extension 14, reducing its stress burden and preventing structural damage caused by excessive local stress.
[0056] Furthermore, this structure facilitates the assembly and disassembly of the buffer component, improving maintenance convenience. The cooperation between the second extension 16 and the limiting groove 23 further enhances the positioning accuracy and operational reliability of the buffer component.
[0057] In summary, this technical solution, by setting the second extension 16 and its cooperation structure with the limiting groove 23, effectively supports and disperses the force of the first extension 14, solves the problem of easy deformation and wear of the first extension 14, thereby improving the stability, durability and overall service life of the buffer assembly 100, and achieving the technical effect of structural stability and buffer protection.
[0058] In the axial direction of the fixing hole 35, the length of the inner sleeve 30 is greater than or equal to the distance between the first buffer 10 and the second buffer 20, so that the inner sleeve 30 is higher than the second buffer 20, thereby preventing the fastener 300 from directly contacting the second buffer 20. This technical solution addresses the technical problem in existing structures where the fastener 300 directly contacts the second buffer 20, which easily leads to deformation and damage of the buffer under pressure, affecting the buffering performance and component life.
[0059] Specifically, by designing the length of the inner sleeve 30 to be greater than or equal to the distance between the first buffer 10 and the second buffer 20, the inner sleeve 30 is ensured to protrude above the second buffer 20 after installation. When the fastener 300 is tightened through the fixing hole 35, the fastener 300 will act directly on the protruding inner sleeve 30, without directly contacting the second buffer 20. This effectively avoids the squeezing, wear, or damage to the second buffer 20 caused by the fastener 300 during tightening or long-term stress, significantly improving the structural integrity and service life of the second buffer 20.
[0060] Meanwhile, the inner sleeve 30, acting as an isolation and support component 31 between the fastener 300 and the buffer component, can secure the installation positions of the first buffer component 10 and the second buffer component 20, preventing displacement of the buffer components under stress or vibration, and effectively ensuring the stability and buffering performance of the buffer system. Furthermore, this structural design facilitates subsequent assembly and maintenance of the product, improving the reliability and consistency of the overall assembly.
[0061] In summary, this technical solution, by setting the length of the inner sleeve 30 to be greater than or equal to the spacing between the buffer components, makes the inner sleeve 30 higher than the second buffer component 20, thus achieving effective isolation between the fastener 300 and the second buffer component 20. This effectively solves the problem of damage caused by the fastener 300 directly acting on the buffer component, thereby improving the durability of the buffer component and the stability of the component, achieving the technical effects of protecting the buffer component, extending product life, and improving structural reliability.
[0062] Please see Figure 1 and Figure 4As shown, Figure 4 This is a schematic diagram of the structure of a buffer component 100 provided in another embodiment of the present invention.
[0063] The inner sleeve 30 includes a support portion 31 and an overlapping portion 33. The support portion 31 has a fixing hole 35 and a first through hole 18 and a second through hole 21 passing through it in sequence. The overlapping portion 33 is connected to one end of the support portion 31 and extends to connect with the side of the second buffer member 20 away from the first buffer member 10, thereby completely preventing the fastener 300 from contacting the second buffer member 20.
[0064] Specifically, the support portion 31 of the inner sleeve 30 is the main stress-bearing area of the fastener 300. The fastener 300 passes through the fixing hole 35, the first through hole 18, and the second through hole 21 in sequence. When stressed, it acts directly on the support portion 31 without affecting the second buffer member 20. The overlapping portion 33 extends further to the side of the second buffer member 20 away from the first buffer member 10, isolating the second buffer member 20 from the fastener 300. With this structure, the fastener 300 will not come into direct contact with the second buffer member 20 during assembly and use, regardless of the stress, effectively avoiding the risk of the second buffer member 20 being squeezed, worn, deformed, or even damaged by the fastener 300.
[0065] Therefore, this technical solution can completely solve the problem of premature failure of the buffer component caused by the fastener 300 directly acting on the second buffer component 20, greatly improving the structural reliability and service life of the buffer device. At the same time, since the fastener 300 and the buffer component are completely isolated, the buffering performance is also optimized, making the buffering effect more stable and consistent.
[0066] In summary, this technical solution, by adding a support portion 31 and an overlapping portion 33 to the inner sleeve 30 structure and extending the overlapping portion 33 to the outside of the second buffer member 20, achieves complete isolation between the fastener 300 and the second buffer member 20, completely eliminating the possibility of contact between the fastener 300 and the second buffer member 20, effectively solving the technical problem of the buffer member being easily damaged, and thus achieving the technical effect of improving the durability and performance stability of the buffer assembly 100.
