Description

Technical Field

[0001] This invention relates to a front-mounted reservoir assembly, and more specifically, to a front-mounted reservoir assembly mounted on the front surface of a hydraulic block to supply brake fluid to an integrated braking system. Background Technology

[0002] A braking system must be installed on a vehicle to perform braking, and various types of braking systems have been proposed for the safety of the driver and passengers.

[0003] Traditional braking systems primarily utilize mechanically connected boosters to supply the necessary hydraulic pressure to the wheel cylinders when the driver depresses the brake pedal. However, with increasing market demands for sophisticated vehicle operation and multi-functional braking, a new type of intelligent integrated braking (IDB) system has become widely adopted. This system receives electrical signals from a pedal displacement sensor that senses the driver's braking intention when the driver depresses the brake pedal, and then operates a hydraulic generator based on these signals to supply the required hydraulic pressure to the wheel cylinders.

[0004] An integrated braking system combines a master booster and Electronic Stability Control (ESC) to generate stable and powerful braking force. Typically, such an integrated braking system includes a configuration where a brake pedal operation is output as an electrical signal via a pedal displacement sensor to actuate a motor. Based on the motor's operation, a piston pump in a hydraulic generator produces brake fluid, and an electronic control unit controls this fluid and transmits it to each wheel. Additionally, a master cylinder is located within a hydraulic block forming the hydraulic circuit, allowing direct transmission of brake pedal force to the wheel cylinders in case of abnormal system operation.

[0005] To perform braking via this integrated braking system, a reservoir is provided that supplies brake fluid to the system. Typically, the reservoir stores brake fluid internally and is connected to the upper part of the master cylinder. Additionally, the reservoir can be connected to a piston pump to generate hydraulic pressure via a piston pump located in the hydraulic generation device of the integrated braking system.

[0006] Various reservoirs are installed to supply brake fluid to integrated braking systems, but there is a problem that it is difficult to install reservoirs in the limited space of a vehicle.

[0007] In addition, under driving and partial braking conditions, the oil ports of the brake fluid reservoir are exposed to air, which leads to a decrease in pedal feel and braking performance. Summary of the Invention

[0048] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. These embodiments are provided to fully convey the spirit of the invention to those skilled in the art. The invention is not limited to the embodiments given herein and may be embodied in other forms. To clarify the invention, figures of parts unrelated to the description will be omitted in the drawings, and the dimensions of components may be shown enlarged to aid understanding.

[0049] Figure 1 This is a perspective view illustrating a pre-loaded liquid reservoir assembly according to an embodiment of the present invention. Figure 2 This is a perspective view showing the state in which the main reservoir of the pre-installed reservoir assembly according to an embodiment of the present invention is installed on the front surface of the hydraulic block of an integrated braking system.

[0050] Reference Figure 1 and Figure 2According to an embodiment of the present invention, the pre-installed reservoir assembly 1 may include a main reservoir 100 provided with a plurality of oil ports 130 and a remote reservoir 200 connected to the main reservoir 100. In this case, the main reservoir 100 may be mounted on the front surface of the hydraulic block 30 to supply brake fluid to the integrated braking system. Therefore, before describing the construction of the pre-installed reservoir assembly 1, a brief description of the integrated braking system combined with the main reservoir 100 will be given.

[0051] Typically, an integrated braking system may include: a master cylinder (not shown) connected to the brake pedal; a hydraulic generator (not shown) that measures the displacement of the brake pedal to generate hydraulic pressure; a hydraulic block 30 machined with multiple flow paths to transmit the hydraulic pressure generated by the master cylinder or the hydraulic generator to the wheel cylinders; and an electronic control unit 40 for controlling the flow of hydraulic pressure. In this case, piston pumps for the master cylinder and the hydraulic generator may be installed within the hydraulic block 30, connected to the flow paths. Additionally, solenoid valves are installed at appropriate locations in the multiple flow paths to selectively allow the flow of brake fluid. Therefore, the electronic control unit 40 controls the flow of hydraulic pressure to the wheel cylinders and performs the braking operation by adjusting the respective solenoid valves.

[0052] This integrated braking system is a well-known technology, so a detailed description of it will be omitted.

Figure 7 This is an exploded perspective view showing a remote reservoir of a pre-loaded reservoir assembly according to an embodiment of the present invention. Figure 8 It is shown Figure 7 A floor plan of the interior of the remote storage tank. Figure 9 It is shown Figure 8 Side view of the remote storage tank.

[0055] Reference Figures 1 to 9According to the present invention, the main reservoir 100 can be installed on the front surface of the hydraulic block 30 to supply brake fluid to the master cylinder and the piston pump.

[0056] A main reservoir 120 for storing brake fluid is provided inside the main reservoir 100. The main reservoir 120 is the space formed inside the main upper body 101 and the main lower body 102 of the main reservoir 100 when they are combined. Therefore, the main reservoir 120 can store brake fluid supplied to the integrated braking system.

[0057] The main reservoir 100 may be provided with a first connection port 110 and a plurality of oil ports 130. The first connection port 110 is configured to receive brake fluid from the remote reservoir 200, which will be described below. The plurality of oil ports 130 are connected to the front surface of the hydraulic block 30 to supply brake fluid.

[0058] The first connection port 110 can be integrally set in the upper main body 101, and multiple oil ports 130 can be integrally set in the lower main body 102.

[0059] The upper main body 101 and the lower main body 102 can be thermally fused together to form a single body.

[0060] The first connection port 110 can be connected to the remote storage tank 200 via the connection component 300. The structure connected via the connection component 300 will be described further below.

[0061] As shown in the figure, multiple oil ports 130 can be configured as first to third oil ports 131, 132, and 133. For example, the first oil port 131 and the second oil port 132 can be connected to a first hydraulic chamber (not shown) and a second hydraulic chamber (not shown) formed in the master cylinder, respectively, and the third oil port 133 can be connected to the piston pump hydraulic chamber (not shown) of the hydraulic generating device. This connection structure of the first to third oil ports 131, 132, and 133 is an example, and the present invention is not limited thereto. That is, the first oil port 131 and the third oil port 133 can be connected to the master cylinder, or the second oil port 132 and the third oil port 133 can be connected to the master cylinder.

[0062] Within such a main reservoir 100, at least one partition plate 140 can be provided to divide the main reservoir 120 into multiple reservoirs. Preferably, the main reservoir 120 is divided into two hydraulic chambers supplying brake fluid to the master cylinder and one hydraulic chamber of the hydraulic generating device, respectively.

[0063] More specifically, the partition plate 140 can be configured to divide the main liquid storage chamber 120 into first to third liquid storage chambers 121, 122, and 123. That is, as shown in the figure, the partition plate 140 may include a first partition plate 141 and a second partition plate 142. The first partition plate 141 and the second partition plate 142 may be formed to be spaced apart from each other by a predetermined interval. Therefore, the main liquid storage chamber 120 may include a first main liquid storage chamber 121 formed between the inner wall of the main liquid storage tank 100 and the first partition plate 141, a second main liquid storage chamber 122 formed between the inner wall of the main liquid storage tank 100 and the second partition plate 142, and a third main liquid storage chamber 123 formed between the first partition plate 141 and the second partition plate 142.

[0064] Since the main reservoir 120 is divided into first to third reservoirs 121, 122, and 123, the first oil port 131 can be configured to communicate with the first main reservoir 121, the second oil port 132 can be configured to communicate with the second main reservoir 122, and the third oil port 133 can be configured to communicate with the third main reservoir 123. Therefore, the brake fluid stored in each main reservoir 121, 122, and 123 can flow in and out through each oil port 131, 132, and 133.

[0065] This partition plate 140 can be formed by extending vertically from the bottom surface of the main storage tank 100. At this time, an opening 145 can be formed in a predetermined portion of the partition plate 140. That is, an opening 145 can be formed in the first partition plate 141 and the second partition plate 142 respectively.

[0066] An opening 145 can be formed extending vertically within the partition plate 140. The opening 145 can be configured to communicate with adjacent main liquid storage chambers 121, 122, and 123. Specifically, the first main liquid storage chamber 121 can communicate with the third main liquid storage chamber 123 through the opening 145 formed in the first partition plate 141. Similarly, the second main liquid storage chamber 122 can communicate with the third main liquid storage chamber 123 through the opening 145 formed in the second partition plate 142. Therefore, the first to third main liquid storage chambers 121, 122, and 123 can be connected to each other through the opening 145.

[0067] However, the lower part of the opening 145 can be configured to prevent brake fluid stored in each of the main reservoirs 121, 122, 123 from moving to adjacent main reservoirs 121, 122, 123. That is, as... Figure 4As shown, the lower part of the partition plate 140 is configured to protrude a predetermined length from the bottom surface of the main reservoir 100, such that a predetermined amount of brake fluid stored in the first to third main reservoirs 121, 122, 123 cannot move to another main reservoir 121, 122, 123. This is to ensure that there is a minimum amount of brake fluid in any of the multiple main reservoirs 121, 122, 123, so that braking operation can be performed in the event of brake fluid leakage due to damage to the main reservoir 100 or poor connection.

[0068] According to one aspect of the invention, a baffle 150 may be provided in at least one of the plurality of main reservoirs 121, 122, 123 to increase the flow resistance of the brake fluid. This is because, under vehicle driving and partial braking conditions, the oil port 130 is severely exposed to air, which may cause air to flow into the braking system. For example, brake fluid and air coexist within the main reservoir 100. Therefore, when turning under acceleration conditions, or in the event of emergency braking, the possibility of air flowing into the brake fluid is increased due to the rapid outflow of brake fluid from the main reservoir 120 through the oil port 130. Therefore, to prevent the rapid outflow of brake fluid through the oil port 130, the baffle 150 is provided to increase the flow resistance of the brake fluid.

[0069] Multiple partitions 150 can be provided, and the multiple partitions 150 can be arranged in a zigzag pattern. More specifically, the partitions 150 may include: a first partition 151, one end fixed to the inner wall of the main liquid storage tank 100, and the other end extending towards the partition plate 140; and a second partition 152, one end fixed to the partition plate 140, and the other end extending towards the inner wall. As shown, the partitions 150 are formed in the second main liquid storage chamber 122, but the invention is not limited thereto. The partitions 150 may be formed in the first main liquid storage chamber 121 or the third main liquid storage chamber 123, or the partitions 150 may be formed in two or more main liquid storage chambers. Preferably, through experimentation, the partitions 150 can be provided in the main liquid storage chambers 121, 122, and 123 connected to the oil ports 131, 132, and 133 exposed to air.

[0070] Multiple first baffles 151 and multiple second baffles 152 can be provided, and the first baffles 151 and the second baffles 152 can be formed extending vertically from the bottom surface of the main reservoir 100. Therefore, the first baffles 151 and the second baffles 152 can be configured such that brake fluid is guided in a zigzag pattern along the first baffles 151 and the second baffles 152 and flows to the second oil port 132.

[0071] The partition 150 and the partition plate 140 can be integrally formed together during the molding of the main storage tank 100. Therefore, the partition 150 and the partition plate 140 are formed in the vertical direction.

[0072] On the other hand, although no reference numerals are added, separate baffles can also be provided in the first main reservoir 121 and the third main reservoir 123. Separate baffles can reduce oil flow caused by vibration or bumps during vehicle operation.

[0073] In addition, the aforementioned partition plate 140 and partition plate 150 can be formed on the lower main body 102, and partition plates and partition plates can also be provided in the upper main body 101 at the portions corresponding to partition plates 140 and partition plates 150.

[0074] A floating part 160 may be provided inside the main lower body 102. The floating part 160 may include: a float 161, which moves up and down with the oil surface in the main reservoir 120 to measure the remaining oil in the main reservoir 120; a float guide 162 for guiding the up and down movement of the float 161; and an oil detection part 165 provided at the lower part of the float 161.

[0075] The float guide 162 can be disposed vertically inside the main reservoir 100. The float 161 can be disposed inside the float guide 162 and moves vertically according to the oil volume. The oil detection unit 165 can be housed in the receiving portion 103 formed in the lower main body 102. The oil sensor inside the oil detection unit 165 can be housed in the receiving portion 103 and detects whether the oil level between the float 161 and the oil detection unit 165 is lower than or equal to a predetermined level.

[0076] When the brake fluid level in the main reservoir 100 is high, the float 161, being less dense than the fluid, floats on the surface of the fluid and moves upwards, moving away from the fluid detection unit 165. When the brake fluid level decreases, causing the surface to drop, the float 161 moves downwards, moving closer to the fluid detection unit 165. At this time, when the fluid level in the main reservoir 100 decreases, the amount of fluid between the float 161 and the fluid detection unit 165 decreases, and the distance between them becomes less than or equal to a predetermined level. The detection sensor can detect this and warn the driver by illuminating a warning light on the vehicle's interior display.

[0077] The remote storage tank 200 can be configured to supply oil to the main storage tank 100. Therefore, the remote storage tank 200 can be configured to be spaced apart from the upper side of the main storage tank 100 by a predetermined interval.

[0078] The remote reservoir 200 may include: a filling section 210 for injecting brake fluid; and a second connection port 220 for supplying brake fluid to the main reservoir 100. Additionally, a remote reservoir chamber 230 for storing brake fluid is provided inside the remote reservoir 200. The remote reservoir chamber 230 is the space formed inside the remote upper body 201 and remote lower body 202 of the remote reservoir 200 when they are combined. Therefore, the remote reservoir chamber 230 can store the brake fluid supplied to the main reservoir 100.

[0079] The oil filling section 210 can be located on the upper remote body 201, and the second connection port 220 can be located on the lower remote body 202. The upper remote body 201 and the lower remote body 202 can be heat-fused together and installed as a single unit.

[0080] The oil filling section 210 is formed on the upper side of the remote upper body 201, through which brake fluid flows in. At this time, the oil filling section 210 may be provided with a cover to prevent brake fluid from leaking to the outside.

[0081] The second connection port 220 can be integrally formed on the remote lower body 202. The second connection port 220 can be connected to the first connection port 110 via the connection component 300. At this time, since the remote reservoir 200 is positioned higher than the main reservoir 100, brake fluid can be easily transferred to the main reservoir 100.

[0082] One end of the connecting component 300 is connected to the first connecting port 110, and the other end is connected to the second connecting port 220 to transfer brake fluid from the remote reservoir 200 to the main reservoir 100. The connecting component 300 can be configured as a rubber hose, allowing easy transfer of brake fluid even when the installation positions of the remote reservoir 200 or the main reservoir 100 are selectively changed.

[0083] A guide plate 240 may be provided within the remote reservoir 200 to increase the flow resistance of the brake fluid guided to the second connection port 220. The guide plate 240 may be formed by extending vertically from the bottom surface of the remote reservoir 200.

[0084] More specifically, the guide plate 240 may include: a first guide partition 241 formed along a direction corresponding to the length direction of the second connection port 220; and a second guide partition 242 disposed between the first guide partition 241 and the inner wall of the remote storage tank 200, along a direction orthogonal to the first guide partition 241.

[0085] A pair of first guide partitions 241 can be provided, and the pair of first guide partitions 241 can be set apart from each other by a predetermined interval. At this time, the second connection port 220 can be set to one side of the remote lower body 202 to prevent brake fluid from easily flowing out of the second connection port 220 through the space between the first guide partitions 241.

[0086] Multiple second guide baffles 242 can be provided, and these second guide baffles 242 can be arranged in a zigzag pattern. That is, when one end of a second guide baffle 242 is fixed to a first guide baffle 241, the other end can extend toward the inner wall; when the other end of a second guide baffle 242 is fixed to the inner wall, one end can extend toward the first guide baffle 241. Therefore, brake fluid can flow along the second guide baffles 242 in a zigzag pattern.

[0087] On the other hand, a flow path hole 243 can be formed in the first guide partition 241 to allow the brake fluid stored between the first guide partition 241 and the inner wall of the remote reservoir 200 to flow. This is because the brake fluid between the first guide partition 241 and the inner wall is supplied in a stagnant state. Therefore, the brake fluid between the first guide partition 241 and the inner wall flows to the second connection port 220 through the flow path hole 243 under conditions where the flow resistance increases through the second guide partition 242. Therefore, it is possible to prevent the brake fluid in the remote reservoir 200 from flowing out of the second connection port 220 rapidly, thereby preventing air from entering.

[0088] On the other hand, the bottom surface of the remote reservoir 200 can be provided with a planar section A and an inclined section B. In this case, a guide plate 240 can be provided in the planar section A. The inclined section B can be set to be inclined so that the brake fluid flows towards the planar section A. Therefore, not only can the brake fluid be easily guided to the side of the second connection port 220 formed in the planar section A, but the flow resistance of the oil can also be increased by the guide plate 240 formed in the planar section A.

[0089] Furthermore, although the remote storage tank 200 according to an embodiment of the present invention is shown and described as having a pair of first guide partitions 241 disposed internally, the present invention is not limited thereto, and a single first guide partition may be disposed. Figure 10 Such an embodiment is shown in the figure.

[0090] Figure 10 This is a plan view showing the interior of a remote reservoir of a pre-loaded reservoir assembly according to another embodiment of the present invention. The same reference numerals as in the above embodiment denote components having the same function.

[0091] Reference Figure 10The remote liquid storage tank 200 according to this embodiment can be the same as the remote liquid storage tank 200 described above, except that it is provided with a first guide partition 241.

[0092] The first guide partition 241 extends along a direction corresponding to the length direction of the second connection port 220, and can extend vertically from the bottom surface of the remote reservoir 200. Multiple second guide partitions 242 can be arranged in a zigzag pattern on both sides of the first guide partition 241. Flow passage holes 243 need to be formed in the first guide partition 241 to allow brake fluid passing through the second guide partitions 242 to flow to the second connection port 220. The flow passage holes 243 not only connect the remote reservoirs 230 on both sides of the first guide partition 241, but also allow brake fluid with increased flow resistance due to passing through the second guide partitions 242 to flow to the second connection port 220.

[0093] As described above, although the present invention has been illustrated by means of limited embodiments and drawings, the present invention is not limited thereto. Those skilled in the art can make various modifications and variations within the scope of the technical concept of the present invention and the equivalents of the appended claims.
