[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0026] See also Figure 1-4 , the utility model provides a technical solution:
[0027] The core design of this anti-deformation engine cylinder is to improve the structural strength and heat dissipation performance of the cylinder, while optimizing the weight distribution to ensure efficient and stable operation of the engine. The following is a detailed description of each component and its connection relationship:
[0028] The cylinder body 1 is the basic structure of the entire engine, and is provided with two obliquely symmetrical cylinder seats 2. This symmetrical layout is not only conducive to the balance of power output, but also can offset vibration to a certain extent and improve stability.
[0029] The cylinder seat 2 is provided with a plurality of precisely machined cylinder holes 3 for installing the cylinder sleeve 4. The cylinder sleeve 4, as a protective layer of the inner wall of the cylinder, withstands the high temperature and high pressure working environment, and ensures the sealing and durability of the cylinder.
[0030] A reinforcing plate 5 is fixedly mounted on the outside of each cylinder block 2. These reinforcing plates 5 are made of high-strength material and are tightly connected to the cylinder block 2 by welding or bolts, etc., effectively strengthening the side wall structure of the cylinder block 2 and enhancing its anti-deformation ability.
[0031] A plurality of heat sinks 6 are also arranged on the reinforcing plate 5. These heat sinks 6 are made of high-efficiency heat-conducting materials and are integrated with the reinforcing plate 5 or installed separately. When the engine is running, the heat sink 6 can quickly dissipate the heat generated by the cylinder block 2 into the air to ensure the stability of the engine operating temperature.
[0032] In order to further optimize the weight distribution of the cylinder body and improve its economy and fuel efficiency, we have specially designed a number of weight-reducing holes 8 on the cross section of the reinforcement plate 5. These weight-reducing holes 8 are not randomly opened, but are determined after precise calculation and simulation analysis to ensure that while reducing the weight, the strength and rigidity of the reinforcement plate 5 will not be significantly reduced.
[0033] In specific implementation, firstly, the number, size and distribution position of the weight-reducing holes 8 are determined according to the material properties, stress conditions and overall design requirements of the reinforcement plate 5. Then, the weight-reducing holes 8 are accurately opened at the corresponding positions of the reinforcement plate 5 by using advanced CNC machining technology. These weight-reducing holes 8 can be circular, elliptical or other shapes, but considering the difficulty of machining and the weight-reducing effect, we usually use a circular or nearly circular shape.
[0034] However, in order to further improve the weight reduction effect and take into account a certain structural strength, in this embodiment, a triangle is specially selected as the cross-sectional shape of the weight reduction hole 8. The triangle has good structural stability, and even at the position of the weight reduction hole 8, the local rigidity of the reinforcing plate 5 can be maintained to a certain extent. At the same time, the edge of the triangle has a certain guiding effect, which helps to reduce tool wear during processing and improve processing accuracy.
[0035] During the processing, the diameter, depth and edge finish of the weight-reducing hole 8 need to be strictly controlled to ensure that it meets the design requirements. After the processing is completed, the reinforcing plate 5 needs to be strictly tested, including dimensional inspection, geometric tolerance inspection and necessary mechanical property testing, to ensure that its quality meets the standards.
[0036] Using a triangle as the cross-sectional shape of the weight-reducing hole 8 has the following advantages over other shapes:
[0037] Better structural stability: The triangle has higher stability, and even if the lightening hole 8 occupies a certain area, the local stiffness of the reinforcing plate 5 can be maintained to a certain extent.
[0038] Easy processing: The triangular shape is relatively simple, and it is easy to control the tool path during processing, reducing processing difficulty and cost.
[0039] The weight reduction effect is significant: under the same area, the triangular weight reduction hole 8 can reduce the weight more effectively than the circular or elliptical shapes, thereby improving the economy of the cylinder body.
[0040] A plurality of first reinforcing ribs 7 are fixedly arranged between the reinforcing plate 5 and the cylinder block 2. These reinforcing ribs are distributed in a mesh or strip shape, further enhancing the connection strength between the cylinder block 2 and the reinforcing plate 5, and preventing local deformation caused by vibration or impact.
[0041] The symmetrically arranged cylinder seats 2 are fixedly connected by a plurality of first connecting rods 9. These connecting rods are arranged at the positions of the cylinder holes 3, ensuring the stable connection of the cylinder seats 2 on both sides in the horizontal and vertical directions. At the same time, inclined and crossed second connecting rods 10 are arranged between the first connecting rods 9, forming a stable mesh structure, which greatly improves the rigidity of the entire cylinder body.
[0042] In order to further improve the strength of the connection, a reinforced fillet 11 is also designed at the connection position between the first connecting rod 9 and the cylinder body 1. These fillet designs help to disperse stress concentration and prevent the connection from cracking due to long-term stress.
[0043] The cylinder body 1 is provided with a plurality of mounting holes 12 for mounting other engine components. In order to improve the strength and stability of the mounting holes 12, a boss 13 protruding from the cylinder body 1 is designed at the position of each mounting hole 12. These bosses 13 not only increase the contact area of the mounting surface, but also firmly fix the components to the cylinder body through fasteners such as bolts.
[0044] A second reinforcing rib 14 is also fixedly arranged between the bosses 13 on one side. The arrangement of these reinforcing ribs further optimizes the structural strength of the cylinder body 1, making it more stable and reliable when facing complex working conditions.
[0045] A plurality of third reinforcing ribs 15 are additionally provided between the cylinder body 1 and the cylinder seat 2. These reinforcing ribs extend from the cylinder body 1 and are connected to the reinforcing structure at the bottom of the cylinder seat 2 to form a more solid overall frame.
[0046] In particular, the hollow first connecting rod 9 is further fixed with an X-shaped reinforcing rib 16. This design not only ensures the lightweight of the connecting rod, but also significantly improves its anti-bending and anti-torsion capabilities, ensuring the stability of the cylinder body under high-intensity working conditions.
[0047] Working principle: When the engine is working, the high-temperature and high-pressure gas in the cylinder pushes the piston to reciprocate, thereby generating power. In this process, the cylinder block 2, the reinforcement plate 5 and various reinforcement ribs work together to ensure the overall strength and stability of the cylinder body. The heat sink 6 continuously dissipates the heat generated by the cylinder block 2 into the air to prevent the cylinder body from overheating and causing performance degradation or damage. Through this series of carefully designed structures and connection relationships, the anti-deformation engine cylinder block of the present invention can maintain an efficient and stable operating state in harsh working environments.
[0048] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
