Description

Technical Field

[0001] This application relates to the field of automotive parts technology, and in particular to an ESP bracket assembly. Background Technology

[0002] With the continuous development of the automotive industry, the Electronic Stability Program (ESP) has become an increasingly important component for ensuring driving safety. The ESP system can monitor and analyze vehicle driving status information in real time, and when the vehicle experiences oversteer, understeer, or other unstable conditions, it can promptly intervene with braking at each wheel to maintain the vehicle's dynamic balance and ensure driving safety.

[0003] In the manufacturing and assembly process of automobiles, the ESP bracket assembly, as a key component supporting and fixing the ESP control unit, plays a crucial role in the stable operation of the ESP system due to its structural design and performance. Relevant prior art, such as Chinese patent application "Automotive ESP Upper Bracket" (application number: CN201520823955.7), includes a mounting plate for installing the ESP. The edge of the mounting plate extends upwards to form three fixing plates for mounting and fixing. The projection positions of the three fixing plates in the vertical direction form a triangle, and the planes on which the three fixing plates are located are parallel to each other. The fixing plates have connection holes perpendicular to the planes on which they are located, and damping rubber rings are installed in the connection holes. The mounting plate also has assembly positioning holes.

[0004] Traditional ESP bracket structures typically connect the bracket to rubber via vulcanization, a method with several drawbacks. Firstly, the vulcanization process requires strict control over the production environment and processes. In actual production, improper control of process parameters can easily lead to delamination between the rubber and the bracket, affecting the bracket's reliability and stability. Secondly, over long-term use, the connection between the rubber and the bracket may gradually loosen due to various vibrations and impact loads during vehicle operation. This reduces the bracket's vibration isolation and support stiffness, affecting the normal operation of the ESP system and potentially causing safety hazards due to connection failure. Utility Model Content

[0005] The technical problem to be solved by this application is to provide an ESP bracket assembly that effectively avoids the risk of delamination, improves connection reliability and vibration isolation effect.

[0006] The technical solution adopted in this application is: an ESP bracket assembly, including a mounting bracket and several buffer components. One end of the mounting bracket is bent upward to form a first vertical plate, and the other end of the mounting bracket is bent downward to form a second vertical plate. The first vertical plate and the second vertical plate are connected by a horizontal plate. The entire mounting bracket includes a first vertical plate, a horizontal plate, and a second vertical plate connected in sequence in a stepped shape. The top surface of the first vertical plate is provided with a mounting slot, and the surface of the second vertical plate is provided with a mounting hole. The buffer components are interference-fitted into the mounting holes, and an inner core is assembled inside the buffer components.

[0007] Compared with the prior art, the advantages of this application are as follows: First, it adopts a mounting bracket and a buffer component that are fitted together, with the buffer component interference-fitted onto the mounting hole and an inner core installed inside, replacing the traditional bracket and rubber vulcanization connection. This avoids the degumming problem caused by improper production environment and parameter control during the vulcanization process, greatly reducing the risk of loosening of the connection under long-term vibration and impact loads, and effectively improving the reliability of the connection.

[0008] Secondly, the design of the buffer components and their assembly with the inner core can better utilize the vibration isolation function of rubber. Compared with traditional structures, various vibrations during vehicle operation can be buffered more effectively, making the working environment of the ESP system more stable, which helps to improve the smoothness and comfort of vehicle driving and ensures the normal operation of the ESP system.

[0009] Finally, the mounting bracket has a stepped design, consisting of a first vertical plate, a horizontal plate, and a second vertical plate connected in sequence. The first vertical plate has mounting slots, and the second vertical plate has mounting holes. This structural layout is reasonable and enhances the overall support rigidity and stability of the bracket, providing a more solid guarantee for the ESP control unit it supports, and enabling it to maintain stable operation under different vehicle operating conditions.

[0010] In this application, for ease of description, the figures in the specification are used as references. Figure 1 The description is based on the product's vertical position, but this does not mean the actual position of the product during use and installation.

[0011] In some embodiments of this application, the second vertical plate and the horizontal plate are connected by an arc surface. A weight-reducing hole is formed in the center of the arc surface, extending to the horizontal plate and the second vertical plate. The weight-reducing hole is oblong in shape. This design, with its arc surface connection, allows for a more uniform stress distribution, reducing the generation of stress concentration areas and thus improving the fatigue strength of the bracket. This makes it less prone to breakage due to stress concentration during long-term use. Furthermore, the weight-reducing hole design effectively reduces material usage and the weight of the bracket while ensuring structural strength, which is beneficial for lightweight automotive design and ultimately improves fuel economy and power performance.

[0012] In some embodiments of this application, the horizontal plate is a rectangular structure, the upper end of the second vertical plate is connected to the horizontal plate, the upper part of the second vertical plate has a trapezoidal structure that is smaller at the top and larger at the bottom, and the two sides of the upper part of the vertical plate are inclined surfaces. The structural design of the second vertical plate effectively enhances the bending and torsional resistance of the second vertical plate, improves the structural strength and stability of the entire support, and the trapezoidal structure of the upper part of the second vertical plate facilitates installation and arrangement.

[0013] In some embodiments of this application, the lower part of the second vertical plate has an inverted triangular structure with mounting holes at each of the three corners. The bottom of the weight-reducing hole extends between the left and right mounting holes, with one of the mounting holes located directly below the weight-reducing hole. The lower part of the second vertical plate with the inverted triangular structure has high strength and stability, enabling it to better withstand forces from different directions and ensuring the stability of the bracket. The mounting holes at the three corners allow for multi-point fixing, making the connection between the bracket and the car body or other components more secure, distributing the force at the fixing points, and reducing stress concentration at individual connection points. The extended design of the weight-reducing hole further reduces the weight of the bracket without weakening the structural strength, thus reducing material costs and resource waste.

[0014] In some embodiments of this application, the buffer component is generally in the shape of a cylindrical tube, with a groove in the middle of its outer circumference that is adapted to the structure of the mounting hole. The cylindrical buffer component has a simple structure, is easy to manufacture and process, and has good elasticity and toughness, which can effectively absorb and buffer vibrations and impact loads during vehicle operation, improve vibration isolation effect, and protect the ESP system from vibration interference.

[0015] The design of the slot matches the mounting hole, allowing for an interference fit between the buffer and the mounting hole. This ensures that the buffer is secure and reliable within the mounting hole, preventing it from loosening. This improves the stability and reliability of the connection and avoids problems such as reduced vibration isolation and connection failure caused by loose buffers.

[0016] In some embodiments of this application, the slot divides the buffer into a first segment and a second segment, which are located on opposite sides of the second vertical plate. The outer diameter of the first segment is smaller than that of the second segment. This segmented design makes the structure of the buffer different on both sides of the second vertical plate. The smaller outer diameter of the first segment reduces friction and interference with one side of the second vertical plate, facilitating the installation and disassembly of the buffer. It also allows for more flexible adaptation to deformation under stress, improving the buffer's cushioning performance. The larger outer diameter of the second segment enhances the support and fixation of the buffer on the other side of the second vertical plate, making the connection between the buffer and the mounting hole tighter. This effectively prevents displacement or loosening of the buffer during operation, ensuring the stability and reliability of the vibration isolation effect.

[0017] In some embodiments of this application, the inner core has an overall T-shaped structure, containing interconnected tubular and ring-shaped components. The tubular components line the inner wall of the buffer chamber, and the ring-shaped components fit against the outer side of the first section, with the outer diameter of the ring-shaped components being larger than that of the first section. The tubular components lining the inner wall of the buffer increase its internal support, preventing excessive deformation under pressure and maintaining stable vibration isolation performance. The ring-shaped components fitting against the outer side of the first section, with an outer diameter larger than that of the first section, further enhance the sealing and fixation between the buffer and the mounting hole, preventing radial displacement of the buffer within the mounting hole, improving connection reliability, and also helping to disperse stress on the buffer under load, thus extending its service life.

[0018] In some embodiments of this application, the horizontal plate is provided with stepped holes, and a buffer pad is installed at each stepped hole, the buffer pad engaging with the stepped hole. The engagement of the buffer pad with the stepped hole allows for secure installation without additional fasteners, simplifying the installation process and improving assembly efficiency. The buffer pad effectively absorbs and buffers vibrations and impacts from different directions, further improving the vibration isolation effect of the bracket and protecting the stable operation of the ESP system.

[0019] Specifically, the bottom of the buffer pad is provided with an inverted fastener, and the bottom of the buffer pad passes through the stepped hole from the small hole side and is engaged with the stepped hole.

[0020] In some embodiments of this application, a localized reinforcing region is provided on the outer periphery of the stepped hole on the horizontal plate, and the thickness of the localized reinforcing region is greater than the thickness of the horizontal plate. This localized reinforcing region effectively improves the strength and rigidity of the horizontal plate around the stepped hole, preventing deformation or damage due to excessive local stress during installation and use, thus ensuring the structural stability and reliability of the horizontal plate. Simultaneously, the reinforcing region is only located in the specific areas requiring reinforcement, without excessively increasing the overall weight of the horizontal plate, which helps maintain the lightweight design of the bracket.

[0021] In some embodiments of this application, two reinforcing plates are provided below the horizontal plate, located on either side of the weight-reducing hole. These reinforcing plates connect the horizontal plate to the second vertical plate. The reinforcing plates further strengthen the connection between the horizontal plate and the second vertical plate, tightly integrating them into a more stable whole and improving the bending and torsional resistance of the bracket. During vehicle operation, especially under heavy loads or complex conditions, the reinforcing plates can better disperse and transmit stress, preventing breakage or deformation at the connection between the horizontal plate and the second vertical plate, thus enhancing the structural integrity and reliability of the entire bracket.

[0029] The present application will now be described in detail with reference to the accompanying drawings.

[0030] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0031] ESP bracket assembly, Example 1 as follows Figures 1 to 2As shown, the system includes a mounting bracket and several buffer components 2. One end of the mounting bracket is bent upwards to form a first vertical plate 3, and the other end is bent downwards to form a second vertical plate 5. The first vertical plate 3 and the second vertical plate 5 are connected by a horizontal plate 4. The entire mounting bracket, consisting of the first vertical plate 3, the horizontal plate 4, and the second vertical plate 5 connected in sequence, forms a stepped structure. This structural layout is reasonable and enhances the overall support rigidity and stability of the bracket, providing a more solid guarantee for the ESP control unit it supports, ensuring stable operation under different vehicle operating conditions. The top surface of the first vertical plate 3 is provided with a mounting slot 6, and the surface of the second vertical plate 5 is provided with mounting holes 7. The buffer components 2 are interference-fitted into the mounting holes 7, and an inner core 8 is installed inside the buffer components 2. The method of using a mounting bracket and a buffer component 2 in combination, with the buffer component 2 interference fit into the mounting hole 7 and an inner core 8 inside, replaces the traditional bracket and rubber vulcanization connection. This avoids the degumming problem caused by improper production environment and parameter control during the vulcanization process, greatly reduces the risk of loosening of the connection under long-term vibration and impact loads, and effectively improves the reliability of the connection.

[0032] The setting of buffer 2 and its assembly with inner core 8 can better utilize the vibration isolation function of rubber. Compared with traditional structures, various vibrations during vehicle operation can be buffered more effectively, making the working environment of the ESP system more stable, which helps to improve the smoothness and comfort of vehicle driving and ensure the normal operation of the ESP system.

[0033] In this application, for ease of description, the figures in the specification are used as references. Figure 1 The description is based on the product's vertical position, but this does not mean the actual position of the product during use and installation.

[0034] Example 2, as Figures 1 to 4 As shown, the second vertical plate 5 and the horizontal plate 4 are connected by an arc surface. A weight-reducing hole 10 is formed in the center of the arc surface, extending to the horizontal plate 4 and the second vertical plate 5. The weight-reducing hole 10 is oblong in shape. This design, with its arc surface connection, allows for a more uniform stress distribution, reducing stress concentration areas and thus improving the fatigue strength of the bracket. This makes it less prone to breakage due to stress concentration during long-term use. Furthermore, the design of the weight-reducing hole 10 effectively reduces material usage and weight while maintaining the structural strength of the bracket, which is beneficial for lightweight automotive design and ultimately improves fuel economy and power performance.

[0035] The horizontal plate 4 has a rectangular structure, and the upper end of the second vertical plate 5 is connected to the horizontal plate 4. The upper part of the second vertical plate 5 has a trapezoidal structure that is smaller at the top and larger at the bottom, and the two sides of the upper part of the vertical plate are inclined surfaces. The structural design of the second vertical plate 5 effectively enhances the bending and torsional resistance of the second vertical plate 5, improves the structural strength and stability of the entire support, and the trapezoidal structure of the upper part of the second vertical plate 5 facilitates installation and arrangement.

[0036] The lower part of the second vertical plate 5 has an inverted triangular structure with mounting holes 7 at each of its three corners. The bottom of the weight-reducing hole 10 extends between the two mounting holes 7 on the left and right, with one of the mounting holes 7 located directly below the weight-reducing hole 10. The lower part of the inverted triangular structure of the second vertical plate 5 has high strength and stability, enabling it to better withstand forces from different directions and ensuring the stability of the bracket. The mounting holes 7 at the three corners allow for multi-point fixing, making the connection between the bracket and the car body or other components more secure, distributing the force at the fixing points, and reducing stress concentration at individual connection points. The extended design of the weight-reducing hole 10 further reduces the weight of the bracket without weakening the structural strength, thus reducing material costs and resource waste.

[0037] The horizontal plate 4 has stepped holes 12, and a buffer pad 11 is installed at the stepped holes 12, engaging with the stepped holes 12. This engagement of the buffer pad 11 with the stepped holes 12 allows for secure installation without additional fasteners, simplifying the installation process and improving assembly efficiency. The buffer pad 11 effectively absorbs and buffers vibrations and impacts from different directions, further improving the vibration isolation effect of the bracket and protecting the stable operation of the ESP system. Specifically, the bottom of the buffer pad 11 has an inverted fastener; the bottom of the buffer pad 11 passes through the stepped hole 12 from one side and engages with it.

[0038] A localized reinforcing region 18 is provided on the horizontal plate 4 around the stepped hole 12, and the thickness of the localized reinforcing region 18 is greater than the thickness of the horizontal plate 4. The localized reinforcing region 18 can effectively improve the strength and rigidity of the horizontal plate 4 around the stepped hole 12, preventing deformation or damage due to excessive local stress during installation and use, and ensuring the structural stability and reliability of the horizontal plate 4. At the same time, the reinforcing region is only set in the specific parts that need reinforcement, without excessively increasing the overall weight of the horizontal plate 4, which is conducive to maintaining the lightweight design of the bracket.

[0039] Two reinforcing plates 19 are provided below the horizontal plate 4, located on either side of the weight-reducing hole 10. These reinforcing plates 19 connect the horizontal plate 4 to the second vertical plate 5. The reinforcing plates 19 further strengthen the connection between the horizontal plate 4 and the second vertical plate 5, tightly binding them into a more stable whole and improving the bending and torsional resistance of the bracket. During vehicle operation, especially under heavy loads or complex conditions, the reinforcing plates 19 can better disperse and transmit stress, preventing breakage or deformation at the connection between the horizontal plate 4 and the second vertical plate 5, thus enhancing the structural integrity and reliability of the entire bracket.

[0040] The rest of the contents of Example 2 are the same as those of Example 1.

[0041] Example 3, as Figures 1 to 4 As shown, the buffer 2 has an overall cylindrical structure, and a groove 13 is provided in the middle of the outer circumference of the buffer 2. The groove 13 is adapted to the structure of the mounting hole 7. The cylindrical buffer 2 has a simple structure, is easy to manufacture and process, and has good elasticity and toughness. It can effectively absorb and buffer the vibration and impact load during vehicle operation, improve the vibration isolation effect, and protect the ESP system from vibration interference.

[0042] The design of the slot 13 matches the mounting hole 7, which allows the buffer 2 to achieve an interference fit with the mounting hole 7. This ensures that the buffer 2 is firmly and reliably installed in the mounting hole 7 and is not easy to loosen, thus improving the stability and reliability of the connection and avoiding problems such as reduced vibration isolation effect and connection failure caused by loosening of the buffer 2.

[0043] The slot 13 divides the buffer 2 into a first segment 14 and a second segment 15, which are located on opposite sides of the second vertical plate 5. The outer diameter of the first segment 14 is smaller than that of the second segment 15. This segmented design makes the structure of the buffer 2 different on both sides of the second vertical plate 5. The smaller outer diameter of the first segment 14 reduces friction and interference with one side of the second vertical plate 5, facilitating the installation and disassembly of the buffer 2. It also allows for more flexible adaptation to deformation under stress, improving the buffer performance of the buffer 2. The larger outer diameter of the second segment 15 enhances the support and fixation of the buffer 2 on the other side of the second vertical plate 5, making the connection between the buffer 2 and the mounting hole 7 tighter. This effectively prevents the buffer 2 from shifting or loosening during operation, ensuring the stability and reliability of the vibration isolation effect.

[0044] The inner core 8 has an overall T-shaped structure, enclosing interconnected tubular components 16 and ring components 17. The tubular components 16 line the inner wall of the buffer chamber, and the ring components 17 fit against the outer side of the first section 14, with the outer diameter of the ring components 17 being larger than that of the first section 14. The tubular components 16, lining the inner wall of the buffer component 2, increase the internal support force of the buffer component 2, preventing excessive deformation under pressure and maintaining stable vibration isolation performance. The ring components 17, fitting against the outer side of the first section 14, with an outer diameter larger than that of the first section 14, further enhance the sealing and fixation between the buffer component 2 and the mounting hole 7, preventing radial displacement of the buffer component 2 within the mounting hole 7, improving connection reliability, and also helping to disperse stress on the buffer component 2 under load, extending its service life.

[0045] The other contents of Example 3 are the same as those of Example 1 or Example 2.
