[0024] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with embodiments

[0025] It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention

[0026] In the embodiments, unless otherwise specified, the means used are all conventional means in the art

[0027] Please refer to Figures 1 - 4 , this application provides a cylinder block structure with a reinforcing plate, including an anti-deformation component 100. A reinforcing plate body 120 is arranged on the top surface of the cylinder block structure, effectively preventing the top surface of the cylinder block 110 from deforming and improving the service life of the cylinder block 110

[0028] Please refer to Figures 1 - 4 , the anti-deformation component 100 includes: a cylinder block 110, a reinforcing plate body 120 and a screw 140. A positioning groove 150 is opened on the cylinder block 110, and the reinforcing plate body 120 is clamped in the positioning groove 150. The area of the positioning groove 150 is equal to the area of the reinforcing plate body 120, and the depth of the positioning groove 150 is equal to the thickness of the reinforcing plate body 120, so that the reinforcing plate body 120 can be inserted into the cylinder block 110 more accurately. A cylinder hole 130 is opened on the cylinder block 110, and a through hole 170 is opened on the reinforcing plate body 120. The cylinder hole 130 and the through hole 170 are arranged corresponding to each other, and the area of the cylinder hole 130 is the same as the area of the through hole 170. The through hole 170 ensures the normal operation of the cylinder block 110. The screw 140 threadedly penetrates through the reinforcing plate body 120, and the screw 140 is also threaded in the cylinder block 110. A first screw hole 160 is opened on the reinforcing plate body 120, and the screw 140 threadedly penetrates through the first screw hole 160. The first screw hole 160 facilitates passing the screw 140 through the reinforcing plate body 120

[0029] A second screw hole 191 is provided on the cylinder block 110. The end thread of the screw 140 is inside the second screw hole 191. The first screw hole 160 and the second screw hole 191 are arranged corresponding to each other. The second screw hole 191 facilitates screwing the end thread of the screw 140 into the cylinder block 110. A hidden groove 190 is provided on the reinforcing plate body 120. The hidden groove 190 and the first screw hole 160 are arranged corresponding to each other. The upper end of the screw 140 is arranged inside the hidden groove 190. The hidden groove 190 facilitates hiding the screw 140 into the reinforcing plate body 120. The cylinder block 110 and the reinforcing plate body 120 are provided with the same positioning pin holes 180. There are two positioning pin holes 180 on both the cylinder block 110 and the reinforcing plate body 120. The positioning pin holes 180 can fix the reinforcing plate body 120 more firmly on the cylinder block 110. The reinforcing plate body 120 is a steel plate, and the cylinder block 110 is a cast aluminum cylinder block. The steel plate of the reinforcing plate body 120 can better protect the top surface of the cast aluminum cylinder block from deformation. There are eight first screw holes 160 on the reinforcing plate body 120. The eight first screw holes 160 are respectively around the cylinder bore 130. The eight first screw holes 160 fix the reinforcing plate body 120 more firmly on the cylinder block 110. The reinforcing plate body 120 is provided with weight-reducing holes 192. The weight-reducing holes 192 are distributed around the cylinder bore 130. While ensuring the rigidity of the reinforcing plate body 120, the weight-reducing holes 192 also reduce the material and the mass of the reinforcing plate body 120.

[0030] Specifically, the working principle of the cylinder block structure with a reinforcing plate: Clamp the reinforcing plate body 120 into the positioning groove 150 on the cylinder block 110 to quickly and accurately align the first screw hole 160 and the second screw hole 191. Then screw the screw 140 into the first screw hole 160 and the second screw hole 191, and make the upper end of the screw 140 enter the hidden groove 190. The hidden groove 190 ensures that the screw 140 will not affect the operation of the cylinder block 110, realizing the fixation of the reinforcing plate body 120 on the cylinder block 110. The cylinder bore 130 on the cylinder block 110 and the through hole 170 on the reinforcing plate body 120 are aligned with each other to ensure the normal operation of the cylinder block 110. The corresponding positioning pin holes 180 on the cylinder block 110 and the reinforcing plate body 120 fix them more firmly together. The reinforcing plate body 120 is a steel plate, and the cylinder block 110 is a cast aluminum cylinder block. The steel plate of the reinforcing plate body 120 can better protect the top surface of the cast aluminum cylinder block from deformation. The reinforcing plate body 120 is provided with weight-reducing holes 192. While ensuring the rigidity of the reinforcing plate body 120, the weight-reducing holes 192 also reduce the material and the mass of the reinforcing plate body 120. There is a reinforcing plate body 120 on the top surface of the cylinder block structure, effectively preventing the top surface of the cylinder block 110 from deforming and improving the service life of the cylinder block 110.
