DETAILED DESCRIPTION

[0060] The following will be combined with the drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application belong to the scope of protection of this application.

[0061] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0062] In the following, in conjunction with the accompanying drawings, the brake pump casting mold and the brake pump integrated with an ABS valve provided in the embodiments of the present application are described in detail through specific embodiments and their application scenarios.

[0063] Embodiment 1:

[0064] like Figures 1 to 12As shown, the embodiment of the present application provides a brake lower pump casting mold, including an upper mold 1 and a lower mold 2, and also includes a plurality of latch grooves 3, which are respectively arranged at the two ends of the front / rear side wall of the upper mold 1; two pairs of latch mechanisms are respectively installed on the left / right side wall of the lower mold 2, each including a pair of flippable latch frames 4 for corresponding sides and a latch head 5 installed at one end of each latch frame 4; an outer cover 6, which can be lifted and sleeved on the outer side of the lower mold 2, and a plurality of auxiliary locks corresponding to the latch frames 4 are movably provided on the inner side walls of the front / rear ends thereof. Stop plate 7; a plurality of linkage mechanisms 9, used to connect each auxiliary locking plate 7 with the lower mold 2 in a transmission manner, and when the outer cover 6 rises / falls, each auxiliary locking plate 7 approaches / moves away from the corresponding locking frame 4; a driving mechanism 8, used to control the rising / falling of the outer cover 6 and the separation / locking of each locking frame 4 and the locking groove 3, each locking head 5 is stationary after being locked with the corresponding locking groove 3, and the outer cover 6 continues to rise, and cooperates with each linkage mechanism 9 to move each auxiliary locking plate 7 until each auxiliary locking plate 7 is pressed against the inner wall and the outer wall of the corresponding locking head 5.

[0065] Meanwhile, a brake lower pump is disclosed, which includes an integrally formed lower pump housing 100 and an ABS housing 200.

[0066] In this embodiment of the present application, due to the adoption of the above-mentioned structure, after the upper mold 1 and the lower mold 2 are molded together, the driving mechanism 8 is actuated to control the outer cover 6 to rise, and the buckle frames 4 are turned over at the same time. After the buckle heads 5 are inserted and buckled with the buckle slots 3, the driving mechanism 8 disconnects the transmission from the buckle frames 4, and continues to control the outer cover 6 to rise, and cooperates with the linkage mechanism 9 to control the auxiliary locking plates 7 to approach the corresponding buckle heads 5, until the side of each locking plate facing the lower mold 2 and the side of each buckle heads 5 facing the inner wall of the outer cover 6 are pressed tightly, completing the mold closing and buckling action of the upper mold 1 and the lower mold 2, and the driving mechanism 8 stops the action;

[0067] Before the upper mold 1 and the lower mold 2 are separated, the driving mechanism 8 is activated to control the outer cover 6 to descend, and each auxiliary locking plate 7 is separated from the contact with the corresponding locking head 5, and each locking frame 4 is flipped in the opposite direction until each locking head 5 is released from the locking state with the corresponding locking groove 3, thereby releasing the fastening action of the upper mold 1 and the lower mold 2, and the upper mold 1 and the lower mold 2 can be separated.

[0068] Integrating the lower pump housing 100 of the brake lower pump with the ABS housing by one-piece casting has the following advantages:

[0069] 1. Structure and space

[0070] Compact and Lightweight: The integrated design reduces the number of components and the overall volume, making the brake system more compact, which helps the lightweight design of the vehicle and helps improve fuel economy and handling performance. At the same time, it reduces the overall weight of the vehicle and improves the vehicle's energy efficiency and range.

[0071] Simplified piping layout: In the traditional split design, the ABS valve body and the brake pump need to be connected by pipes to transfer brake fluid. After integration, these intermediate pipes are omitted, which not only reduces the risk of brake fluid leakage caused by pipe aging and rupture, but also makes the appearance of the braking system more concise, reduces the clutter in the vehicle's engine compartment, and facilitates the installation and maintenance of other components.

[0072] 2. Performance and responsiveness

[0073] Improve response speed: Due to the reduction of pipeline length and connection points, the transmission path of brake fluid in the system is shorter, and the pressure transmission is more direct and rapid, so that the ABS system can respond more quickly to the locking tendency of the wheels and adjust the brake pressure more promptly during emergency braking, thereby effectively shortening the braking distance and improving driving safety.

[0074] Optimized brake pressure control: The integrated design makes the cooperation between the ABS valve body and the brake pump tighter and more precise, which can more accurately control the brake pressure of each wheel, so that the wheel always maintains the best slip rate during braking, further improves braking efficiency and stability, and reduces unstable phenomena such as deviation and side slip during braking.

[0075] 3. Cost and maintenance

[0076] Reduce production costs: The integration of components reduces the procurement, production and assembly costs of components, while also reducing quality problems and scrap rates that may arise from too many components, thereby reducing the manufacturing cost of the vehicle to a certain extent.

[0077] Easy maintenance and inspection: The integrated design allows maintenance personnel to perform overall inspection and maintenance on the integrated module instead of separately inspecting and repairing the ABS valve body and brake pump during fault diagnosis and maintenance, greatly improving maintenance efficiency and reducing maintenance difficulty and cost. Moreover, if a component fails, it is relatively simple to replace the integrated module as a whole, reducing maintenance time and workload.

[0078] Embodiment 2:

[0079] like Figures 2 to 12As shown, in this embodiment, in addition to the structural features of the aforementioned embodiments, it also includes a pair of side grooves 10, which are respectively arranged on the left / right side walls of the lower mold 2; a plurality of vertical grooves 11, which are respectively arranged at the four corners of the lower mold 2 and connected with the corresponding side grooves 10; a transverse groove, which connects the pair of side grooves 10, and has transmission grooves 12 connected with the front / rear side walls of the lower mold 2 at both ends. Each locking frame 4 is L-shaped, with a torsion spring installed at the bend and installed at one end of the corresponding side groove 10 through a hinge shaft. The locking head 5 is installed at one end of the locking frame 4 and extends upward through the corresponding vertical groove 11, and the other end extends to the middle section of the side groove 10, and cooperates with the driving mechanism 8 in transmission. The linkage mechanism 9 is installed in the side groove 10.

[0080] Furthermore, the driving mechanism 8 includes a sliding frame 81, which is driven by a straight-moving actuator 82 and can be slidably installed in the transverse groove forward and backward, and the left and right sides extend into the corresponding side grooves 10 respectively; a pair of linkage arms 83, which are movably installed in each transmission groove 12, one end of which is hinged to the front / rear end of the sliding frame 81, and the other end is hinged to the top / bottom end of the front / rear inner wall of the outer cover 6; a plurality of flip control grooves 84, which are respectively arranged on the top surface of the lower section of each linkage arm 83, and all include a recessed groove 841 and a retaining groove 842; a plurality of push blocks 85, which are respectively fixed on the front and rear ends of the left and right sides of the sliding frame 81, and slideably cooperate with the corresponding flip control grooves 84.

[0081] Preferably, each groove 841 is arranged at the rear end of the corresponding retaining groove 842, and each retaining groove 842 located on the front side extends downward away from the corresponding groove 841 end, and each retaining groove 842 on the rear side extends upward away from the corresponding groove 841 end.

[0082] In this embodiment of the present application, due to the adoption of the above-mentioned structure, the straight-moving actuator 82 (which can be a cylinder, a hydraulic cylinder or an electric push rod) is actuated to push the sliding frame 81 to slide toward the front end or rear end of the lower mold 2. When the sliding frame 81 moves forward in the transverse groove, each push block 85 slides from the corresponding groove 841 to the corresponding retaining groove 842, pushing each buckle lock frame 4 to flip around the corresponding hinge axis, so that each buckle lock head 5 moves into the corresponding buckle lock groove 3, and each torsion spring is deformed to store elastic potential energy. After the locking action is completed with the corresponding locking groove 3, each push block 85 enters the holding groove 842 and cooperates with each torsion spring to keep the flip angle of each locking frame 4 at this time. In this process, the front linkage arm 83 and the rear linkage arm 83 are flipped around the hinge point with the sliding frame 81, and the ends of the pair of linkage arms 83 away from the sliding frame 81 are both raised, pushing / pulling the outer cover 6 to continue to rise until each auxiliary locking plate 7 contacts the corresponding locking head 5, and the straight actuator 82 stops;

[0083] When the sliding frame 81 moves backward in the transverse groove, each push block 85 slides from the corresponding retaining groove 842 to the corresponding recessed groove 841, and the front end linkage arm 83 and the rear end linkage arm 83 both flip around the hinge point with the sliding frame 81. The end of a pair of linkage arms 83 away from the sliding frame 81 both descends, pushing / pulling the outer cover 6 to descend until each auxiliary locking plate 7 is away from the corresponding buckle lock head 5, and each push block 85 enters the corresponding recessed groove 841 and moves to the lowest point of the corresponding recessed groove 841. Each torsion spring deforms to release elastic potential energy, pushing each buckle lock frame 4 to flip around the corresponding hinge axis, so that each buckle lock head 5 moves out of the corresponding buckle lock groove 3 until the buckle lock state of each buckle lock head 5 and the corresponding buckle lock groove 3 is released, and the straight-moving actuator 82 stops.

[0084] Embodiment 3:

[0085] like Figure 4 and Fig.11 As shown, in this embodiment, in addition to the structural features of the aforementioned embodiments, the linkage mechanism 9 includes a plurality of guide columns 91, which are symmetrically fixed on the front / rear end side walls of the lower mold 2; a plurality of guide grooves 92, which are respectively arranged on each auxiliary locking plate 7 and slidably cooperate with the corresponding guide columns 91, and each includes an upright section 921 and an inclined section 922, the upper end of the inclined section 922 is connected to the lower end of the upright section 921, and the other end extends downwardly at an angle toward the center position of the lower mold 2.

[0086] Preferably, a plurality of slide grooves 13 are symmetrically arranged on the front / rear end side walls of the outer cover 6, and a dovetail groove is provided at the bottom; a plurality of dovetail sliders 14 are respectively fixed at the bottom end of each auxiliary locking plate 7 and slidably cooperate with the corresponding dovetail groove.

[0087] In this embodiment of the present application, due to the adoption of the above-mentioned structure, when the outer cover 6 rises, each auxiliary locking plate 7 and the guide groove 92 also rise at the same time. Relatively speaking, each guide column 91 slides from the upper end of the corresponding upright section 921 to the bottom end of the inclined section 922. When each guide column 91 moves to the connection position of the corresponding upright section 921 and the inclined section 922, each buckle lock head 5 has moved to complete the buckle lock with the corresponding buckle lock groove 3, and each buckle lock head 5 completely enters the corresponding vertical groove 11, and the outer side wall is flush with the side surface of the lower mold 2. The outer cover 6 continues to rise, and each guide column 91 enters the inclined section 922 and slides to its lower end, so that the corresponding auxiliary locking plate 7 can be pushed to move toward the corresponding buckle lock head 5 until each auxiliary locking plate 7 is pressed against the adjacent side of the buckle lock head 5. In this process, the dovetail slider 14 slides in the corresponding dovetail groove, and the auxiliary locking plate 7 slides in the slide groove 13;

[0088] When the outer cover 6 descends, each auxiliary locking plate 7 and the guide slot 92 also descends at the same time. Relatively speaking, each guide column 91 slides from the lower end of the corresponding inclined section 922 to the upper end of the upright section 921, pushing the corresponding auxiliary locking plate 7 to move away from the corresponding buckle lock head 5, until each auxiliary locking plate 7 is away from the corresponding buckle lock head 5, each guide column 91 moves to the connection position between the corresponding upright section 921 and the inclined section 922, each buckle lock head 5 still maintains the buckle lock with the corresponding buckle lock slot 3, and the outer cover 6 continues to descend. The guide column 91 enters the upright section 921 and slides toward its upper end. At this time, each push block 85 enters the corresponding groove 841 and moves to the lowest point of the corresponding groove 841. The deformation of each torsion spring releases elastic potential energy, pushing each locking frame 4 to flip around the corresponding hinge axis, so that each locking head 5 moves toward the outside of the corresponding locking groove 3 until the locking state of each locking head 5 and the corresponding locking groove 3 is released. During this process, the dovetail slider 14 slides in the corresponding dovetail groove, and the auxiliary locking plate 7 slides in the slide groove 13.

[0089] Embodiment 4:

[0090] like Figure 11 to Figure 12 As shown, in this embodiment, it also includes a plurality of elastic members 15, which are used to movably mount each buckle lock head 5 on the upper end of the corresponding buckle lock frame 4; a plurality of closing mechanisms 16, which are used to drive each auxiliary locking plate 7 with the corresponding buckle lock frame 4 and the buckle lock head 5, and when the auxiliary locking plate 7 approaches / moves away from the corresponding buckle lock frame 4, the buckle lock head 5 is controlled to descend / rise;

[0091] Furthermore, the elastic member 15 includes an insertion hole 151, which is arranged at the lower end of the buckle lock head 5 and has a spring 153 at the inner end; a column 152, which is fixed on the upward end surface of the buckle lock frame 4 and is slidably inserted in the insertion hole 151; an anti-slip groove 154, which passes through the column 152 from front to back; and an anti-slip rod 155, which is inserted in the anti-slip groove 154 and has its two ends fixedly connected to the inner wall of the insertion hole 151.

[0092] Furthermore, the closing mechanism 16 includes a pair of clamping blocks 161, which are respectively fixed on the side walls of the locking frame 4 and the locking head 5 facing the outer cover 6; a locking notch 162, which is arranged on the side wall of the auxiliary locking plate 7 facing the locking frame 4, and the upper and lower side surfaces are inclined, and is used to cooperate with the pair of clamping blocks 161 to control the locking head 5 to move toward the locking frame 4.

[0093] In this embodiment of the present application, due to the adoption of the above-mentioned structure, during the movement of each auxiliary locking plate 7 toward the corresponding buckle lock head 5, each buckle lock notch 162 moves toward a pair of clamping blocks 161, and then the upper and lower side walls contact the upper side wall of the upper clamping block 161 and the lower side wall of the lower clamping block 161 respectively. As the auxiliary locking plate 7 continues to move, each clamping block 161 moves toward the inner end of the buckle lock notch 162, and each upper clamping block 161 moves downward in this process until it closes with the corresponding lower clamping block 161. Correspondingly, each buckle lock head 5 also descends, and the top of each plug column 152 approaches the top of the corresponding plug hole 151. The spring 153 is compressed and shortened, and the top of the buckle lock head 5 is bent. The inner end surface of the buckle lock groove 3 is provided with a groove for buckling with the bent top of the buckle lock head 5. The descent of the buckle lock head 5 makes the bent bottom surface of its top contact with the bottom surface of the groove set in the buckle lock groove 3, thereby making the upper mold 1 and the lower mold 2 approach each other, and the contact surface is further pressed;

[0094] When each auxiliary locking plate 7 moves away from the corresponding locking head 5, each clamping block 161 moves toward the outer end of the corresponding locking notch 162, and the spring 153 releases its elastic potential energy to push the locking head 5 up until each clamping block 161 is disengaged from the corresponding locking notch 162, and the pressing state between the locking head 5 and the locking groove 3 is released.
