DETAILED DESCRIPTION

[0029] In order to further understand the content of the utility model, the utility model is described in detail in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments are only used to explain the utility model but not to limit it.

[0030] With the gradual improvement of the performance level and maturity of the intelligent driving system, the functions of the vehicle's braking system are becoming more and more perfect. These are all achieved through the structure of the valve block 1 in the braking system. Generally, various circuits and other structures are integrated inside the valve block 1, so the integration of the internal structure of the valve block 1 is required to be high. However, since the size of the valve block 1 itself is fixed, the space between the various circuits formed inside the valve block 1 is small, that is, the internal space of the valve block 1 is limited, so the internal structure of the valve block 1 needs to be rationally arranged.

[0031] In view of this, combined with Figure 1-6As shown, the present embodiment discloses a valve block structure of a hydraulic brake system, wherein the valve block 1 comprises a valve side 100 and a motor side 200 which are arranged opposite to each other, and a fixed side 300 which is adjacent to both the valve side 100 and the motor side 200; a simulation cavity hole 110 for simulating pedal feel is provided on the valve side 100 of the valve block 1, and the simulation cavity hole 110 is a blind hole; a first valve hole 120 is also provided on the valve side 100 of the valve block 1, and the first valve hole 120 is also a blind hole, in which a control valve with corresponding functions can be installed for use; a master brake cylinder hole 310 for forming a master brake cylinder is provided on the fixed side 300 of the valve block 1, and the master brake cylinder hole 310 is a blind hole, and the master brake cylinder hole 310 has two chambers, namely a first chamber 311 and a second chamber 312, wherein the first chamber 311 is closer to the fixed side 300 of the valve block 1 than the second chamber 312.

[0032] Furthermore, a first flow channel hole 2 for connecting the simulation cavity hole 110 and the first valve hole 120, and a second flow channel hole 3 for connecting the first valve hole 120 and the first chamber 311 are formed inside the valve block 1, so that the simulation cavity hole 110 can be connected to the first chamber 311 through the first valve hole 120. Figure 1 and Figure 3 As shown, it can be understood that the position of the first valve hole 120 is between the simulation cavity hole 110 and the master brake cylinder hole 310, so that the straight-line distance between the first valve hole 120 and the simulation cavity hole 110 and the master brake cylinder hole 310 is relatively short, for example, the first valve hole 120 is connected to the simulation cavity hole 110 through the first flow channel hole 2; at the same time, the position of the first valve hole 120 is also between the first chamber 311 and the second chamber 312, so that the distance between the first valve hole 120 and the first chamber 311 and the second chamber 312 can be kept relatively short, for example, the distance between the first valve hole 120 and the first chamber 311 is connected. The second flow channel hole 3 is connected through the inclined; through the above arrangement, the first valve hole 120 can better maintain a shorter distance with the simulation cavity hole 110, the first chamber 311 and the second chamber 312, so that the internal structure of the valve block 1 is more compact and the layout is more reasonable, so that the connection can be achieved through a shorter flow channel hole, such as the first flow channel hole 2 and the second flow channel hole 3; when the valve block 1 is in working state, the first valve hole 120, the simulation cavity hole 110, the first chamber 311 and the second chamber 312 can achieve rapid response through the shorter flow channel hole, thereby improving the performance of the vehicle's braking system.

[0033] The valve block 1 also includes a first side 400 adjacent to the valve side 100, the motor side 200 and the fixed side 300, and a second side 500 opposite to the first side 400.
