Description

Technical Field

[0001] This utility model relates to the field of work machinery technology, specifically to braking control devices, braking systems, and work machinery. Background Technology

[0002] Backhoe loaders are multi-purpose construction machines that integrate loading and digging functions. They operate in complex environments and often require parking on slopes or uneven terrain. Currently, existing backhoe loaders typically use a mechanical handbrake, which is activated by pulling a cable to directly engage the rear axle brake, thus achieving parking.

[0003] Currently, conventional mechanical handbrakes typically include a mounting base and a swingable handle return spring. The end of the handle is connected to the brake cable. When the handle needs to be swung to brake, the driver usually relies entirely on the strength of their arm to overcome the tension of the brake spring. For operators with less strength, pulling the handbrake is very difficult and may result in the handbrake not being pulled to the designated position, thus failing to generate sufficient braking force. Utility Model Content

[0004] This utility model provides a braking control device, a braking system, and a working machine to solve the problem of difficult operation of existing mechanical handbrakes.

[0005] In a first aspect, this utility model provides a braking control device, having a first direction, comprising: a mounting base having a hinge structure and a guide structure spaced apart along the first direction, the guide structure extending away from the hinge structure, and the mounting base having a dividing line passing sequentially through the hinge structure and the guide structure along the first direction; a brake lever including a mating section, a connecting section, and a gripping section connected sequentially, the mating section being hinged to the hinge structure at one end near the connecting section, and the other end being connected to a brake cable; a connecting rod having a first mating end at one end and a second mating end at the other end, the first mating end being hinged to the connecting section, and the second mating end being slidably mated to the guide structure; and an elastic element located on the side of the guide structure away from the hinge structure, the second mating end being connected to the mounting base via the elastic element; wherein the brake lever has a first swing position in an unlocked state and a second swing position in a braking state, and when the brake lever swings from the first swing position to the second swing position, the angle between the extension line of the brake lever and the dividing line first decreases and then increases.

[0006] Beneficial effects: While the brake lever is hinged to the hinged structure, it also cooperates with the guide structure through the connecting rod. When the brake lever swings, it will synchronously drive the connecting rod to move. When the brake lever swings from the first swing position to the second swing position, as the angle between the extension line of the brake lever and the dividing line gradually decreases, the brake lever needs to overcome the tension of the brake cable and the elastic force of the elastic element. When the extension line of the brake lever coincides with the dividing line, the elastic force of the elastic element is at its maximum and the direction of the tension is perpendicular to the direction of movement of the brake lever. At this time, the brake lever only needs to overcome the tension of the brake cable when moving. When the extension line of the brake lever passes through the dividing line and the angle between the two gradually increases, the tension of the elastic element will assist the movement of the brake lever. Therefore, it can effectively reduce the resistance when the brake lever approaches the second swing position, making it easier for the operator to move the brake lever to the second swing position, improving the braking reliability of the handbrake, and effectively solving the problem of difficult operation of existing mechanical handbrakes.

[0007] In one optional embodiment, the mounting base further has a limiting structure disposed on one side of the hinge structure. The limiting structure has an abutting surface. When the brake rod abuts against the abutting surface, the brake rod is in a second swing position. Any point on the abutting surface and the connecting line of the hinge structure form a limiting line. The angle between the limiting line and the dividing line is an acute angle.

[0008] Beneficial effects: The limiting structure can reliably limit the brake lever. When the angle between the limiting line and the dividing line is an acute angle, the elastic element is still in a state of greater elasticity, which can more stably keep the brake lever in the second swing position.

[0009] In one optional implementation, when the brake lever is in the second swing position, the angle between the extension line of the brake lever and the dividing line is angle A, where angle A is greater than 0 degrees and less than or equal to 10 degrees.

[0010] Beneficial effects: The smaller angle of angle A not only reduces the travel of the brake lever during the process of reaching the second swing position, but also makes it easier to pull the brake lever, which is located in the second swing position, toward the first swing position.

[0011] In one alternative embodiment, the brake lever has a first through groove that passes through the mating section and the connecting section, and one end of the connecting rod passes through the first through groove and is hinged to the connecting section via a first hinge shaft.

[0012] Beneficial effects: This type of brake lever connects to the connecting rod, resulting in a more even distribution of force on the brake lever as a whole, and a more stable and reliable connecting rod structure.

[0013] In one optional embodiment, the braking control device further has a second direction perpendicular to the first direction; the connecting section is provided with a strip-shaped hole extending along the second direction, the strip-shaped hole extending along the extension direction of the brake rod and communicating with the first through groove, and the first hinge shaft passing through the strip-shaped hole.

[0014] Beneficial effects: This type of connecting section can adjust the position of the brake lever when it is in the first swing position by adjusting the position of the first hinge shaft in the strip hole, which can effectively improve the positional flexibility of the brake lever.

[0015] In one alternative embodiment, the brake lever further includes a movable adjusting section inserted into a first through slot and having a second through slot for a connecting rod to pass through. The adjusting section has an adjusting hole extending in the same direction as the strip hole. A first hinge shaft passes through the adjusting hole and connects to the strip hole. The adjusting section is used to connect to the brake cable. The hinge structure has a second hinge shaft that passes through a mating section and into the adjusting hole.

[0016] Beneficial effect: The adjusting section is used to connect with the brake cable.

[0017] In one alternative embodiment, the brake lever further includes an adjustment structure disposed inside the grip section, one end of the adjustment structure being connected to the adjustment section and the other end protruding from the end of the grip section, the adjustment structure being adapted to drive the adjustment section to move.

[0018] Beneficial effects: This type of adjustment structure can make full use of the space inside the grip section and improve the space utilization rate inside the brake lever. Operators can easily and quickly change the position of the adjustment section by using the adjustment structure, which can further improve the convenience of adjusting the tightness of the brake cable.

[0019] In one optional embodiment, the adjustment structure includes an adjustment part and a connecting part. The adjustment part is rotatably inserted into the holding section, with one end of the holding section protruding. The connecting part is disposed in the holding section and sleeved on the outside of the adjustment part. The connecting part is threadedly connected to the adjustment part and fixedly connected to the adjustment section. The adjustment part is adapted to drive the connecting part to move along the axial direction by rotating itself.

[0020] Beneficial effects: The overall adjustment structure is simple and reliable. Operators can easily and quickly adjust the position of the adjustment section by rotating the adjustment part, thereby achieving the effect of changing the tension of the cable at the grip section.

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0027] The following is combined Figures 1 to 6 The following describes embodiments of the present invention.

[0028] According to an embodiment of the present invention, a braking control device is provided, having a first direction X, comprising: a mounting base 1, a brake lever 2, a connecting rod 3, and an elastic element 4.

[0029] Mounting base 1 has a hinge structure 101 and a guide structure 102 spaced apart along a first direction X. The guide structure 102 extends in a direction away from the hinge structure 101. Along the first direction X, mounting base 1 has a dividing line 103 that passes through the hinge structure 101 and the guide structure 102 in sequence. Brake lever 2 includes a mating section 201, a connecting section 202 and a gripping section 203 connected in sequence. The end of the mating section 201 near the connecting section 202 is hinged to the hinge structure 101, and the end away from the connecting section 202 is used to connect to the brake cable. The connecting rod 3 has a first mating end 301 at one end and a second mating end 302 at the other end. The first mating end 301 is used to hinge with the connecting section 202, and the second mating end 302 is used to slide with the guide structure 102. The elastic element 4 is located on the side of the guide structure 102 away from the hinge structure 101, and the second mating end 302 is connected to the mounting base 1 through the elastic element 4. The brake lever 2 has a first swing position in the unlocked state and a second swing position in the braking state. When the brake lever 2 swings from the first swing position to the second swing position, the angle between the extension line 204 of the brake lever 2 and the dividing line 103 first decreases and then increases.

[0030] In the braking control device of this embodiment, the brake lever 2 is hinged to the hinge structure 101 and also cooperates with the guide structure 102 through the connecting rod 3. When the brake lever 2 swings, it will synchronously drive the connecting rod 3 to move. When the brake lever 2 swings from the first swing position to the second swing position, as the angle between the extension line 204 of the brake lever 2 and the dividing line 103 gradually decreases, the brake lever 2 needs to overcome the tension of the brake cable and the elastic force of the elastic element 4. When the extension line 204 of the brake lever 2 coincides with the dividing line 103, the elastic force of the elastic element 4 is at its maximum. When the pulling force is large and the direction of the pulling force is perpendicular to the direction of movement of the brake lever 2, the brake lever 2 only needs to overcome the tension of the brake cable when it moves. When the extension line 204 of the brake lever 2 passes through the dividing line 103 and the angle between the two gradually increases, the pulling force of the elastic element 4 will assist the movement of the brake lever 2. Therefore, it can effectively reduce the resistance when the brake lever 2 approaches the second swing position, so that the operator can move the brake lever 2 to the second swing position more easily, improve the braking reliability of the handbrake, and effectively solve the problem of difficult operation of the existing mechanical handbrake.

[0031] In addition, such as Figure 3 and Figure 6 As shown, Figure 3 This refers to the state when brake lever 2 is in the first swing position. Figure 6 When the brake lever 2 is in the second swing position, the elastic element 4 applies a pulling force to the brake lever 2 through the connecting rod 3, which can make the brake control device become self-locking. When it is necessary to return the brake lever 2 to the first swing position, the operator can pull the brake lever 2 in the opposite direction.

[0032] Wherein, the first direction X refers to Figure 1 The direction of "X" indicated by the middle arrow is introduced simply to facilitate the description of spatial relationships. The first direction X can be the direction of gravity or a direction that has an angle with the direction of gravity, and can be flexibly selected according to the needs.

[0033] Specifically, the specific structure of the mounting base 1 is not limited; it can be an integral structure or a split structure. The specific form of the hinge structure 101 is not limited; it can be a hinge shaft or a hinge cylinder set on the hinge plate. The specific form of the guide structure 102 is not limited; it can be a guide groove, a guide hole, etc., as long as it can guide the second mating end 302.

[0034] Furthermore, in order to ensure that the pulling action of the elastic element 4 is stable and reliable, the elastic element 4 also extends along the first direction X. As an alternative implementation, the second mating end 302 can also be directly connected to the vehicle body through the elastic element 4.

[0035] In one embodiment, such as Figure 2 As shown, the mounting base 1 also has a limiting structure 104 disposed on one side of the hinge structure 101. The limiting structure 104 has an abutment surface 1041. When the brake lever 2 abuts against the abutment surface 1041, the brake lever 2 is in the second swing position. Any point on the abutment surface 1041 and the connecting line of the hinge structure 101 form a limiting line. The angle between the limiting line and the dividing line 103 is an acute angle. The limiting structure 104 can reliably limit the brake lever 2. When the angle between the limiting line and the dividing line 103 is an acute angle, the elastic element 4 is still in a state of greater elasticity, which can more stably keep the brake lever 2 in the second swing position.

[0036] In one embodiment, such as Figure 6 As shown, when the brake lever 2 is in the second swing position, the angle between the extension line 204 of the brake lever 2 and the dividing line 103 is angle A. The angle of angle A is greater than 0 degrees and less than or equal to 10 degrees. The smaller angle of angle A not only reduces the stroke of the brake lever 2 in the process of reaching the second swing position, but also makes it easier to pull the brake lever 2 in the second swing position toward the first swing position.

[0037] Preferably, such as Figure 2 and Figure 6 As shown, angle A is 5 degrees. Figure 2 The dotted line shown is perpendicular to the first direction X. When the brake lever 2 swings from the position of the dotted line to the second swing position, the angle of the swing of the brake lever 2 is 95 degrees.

[0038] It is understandable that, as an alternative implementation method, the angle of angle A can also be 6 degrees, 7 degrees, 8 degrees, 9 degrees, etc.

[0039] In one embodiment, such as Figures 3 to 5 As shown, the brake lever 2 has a first through groove 205 that passes through the mating section 201 and the connecting section 202. One end of the connecting rod 3 passes through the first through groove 205 and is hinged to the connecting section 202 through the first hinge shaft 303. With this type of brake lever 2 connected to the connecting rod 3, the brake lever 2 is subjected to more uniform force, and the resulting connecting rod structure is more stable and reliable.

[0040] It is understood that, as an alternative implementation, the connecting rod 3 may also be provided on one side of the brake rod 2 along the axial direction of the first hinge shaft 303, with the first hinge shaft 303 passing through the connecting rod 3 and the connecting section 202 in sequence to hinge the two together.

[0041] In one embodiment, such as Figures 3 to 5 As shown, the braking control device also has a second direction Y that is perpendicular to the first direction X; The connecting section 202 is provided with a strip hole 206 that runs through the second direction Y. The strip hole 206 extends along the extension direction of the brake lever 2 and communicates with the first through groove 205. The first hinge shaft 303 passes through the strip hole 206. With this type of connecting section 202, the position of the brake lever 2 when it is in the first swing position can be adjusted by adjusting the position of the first hinge shaft 303 in the strip hole 206, which can effectively improve the positional flexibility of the brake lever 2.

[0042] Specifically, such as Figure 1 As shown, when the brake lever 2 is in the first swing position, it is mainly supported by the connecting rod 3. When the hinge position between the connecting rod 3 and the brake lever 2 changes, the final support position of the two will also change.

[0043] In one embodiment, such as Figures 2 to 5 As shown, the brake lever 2 also has a movable adjustment section 207. The adjustment section 207 is inserted into the first through slot 205 and has a second through slot 2071 for the connecting rod 3 to pass through. The adjustment section 207 has an adjustment hole 2072 whose extension direction is consistent with the strip hole 206. The first hinge shaft 303 passes through the adjustment hole 2072 and is connected to the strip hole 206. The adjustment section 207 is used to connect with the brake cable.

[0044] The hinge structure 101 has a second hinge shaft 1011, which passes through the mating section 201 and enters the adjustment hole 2072.

[0045] Since the adjusting section 207 is connected to the brake cable, the brake cable can be tensioned by moving the adjusting section 207 toward the bottom of the first through groove 205, and the brake cable can be loosened by moving the adjusting section 207 toward the opening of the first through groove 205. By changing the position of the adjusting section 207, the tension of the brake cable can be adjusted conveniently and quickly, which significantly improves the flexibility of the brake control device.

[0046] In addition, since an adjustment hole 2072 is provided for the first hinge shaft 303 and the second hinge shaft 1011 to pass through, the adjustment section 207 can not only avoid the first hinge shaft 303 and the second hinge shaft 1011 when it moves, but the first hinge shaft 303 and the second hinge shaft 1011 can also effectively limit the adjustment section 207. This not only prevents the adjustment section 207 from coming out of the first through groove 205, but also prevents the adjustment section 207 from rotating under the pull of the brake cable, thus improving the working reliability of the brake control device.

[0047] Specifically, such as Figure 5As shown, the second hinge shaft 1011 is a shorter shaft. The two second hinge shafts 1011 pass through the mating section 201 from opposite sides and then enter the adjustment hole 2072. This type of second hinge shaft 1011 can effectively avoid the connecting rod 3 and prevent the connecting rod 3 from interfering with the second hinge shaft 1011 when passing through the second through groove 2071.

[0048] It is understood that, as an alternative implementation, if the connecting rod 3 is arranged along the axial direction of the first hinge shaft 303 on one side of the brake rod 2, and the first hinge shaft 303 passes through the connecting rod 3 and the connecting section 202 in sequence to hinge the two, the second hinge shaft 1011 at this time can also be a longer shaft that passes through the adjustment hole 2072.

[0049] In one embodiment, such as Figure 2 As shown, the brake lever 2 also includes an adjustment structure 208, which is located inside the grip section 203. One end of the adjustment structure 208 is connected to the adjustment section 207, and the other end protrudes from the end of the grip section 203. The adjustment structure 208 is adapted to move the adjustment section 207. This type of adjustment structure 208 can make full use of the space inside the grip section 203 and improve the space utilization rate inside the brake lever 2. The operator can conveniently and quickly change the position of the adjustment section 207 by using the adjustment structure 208, which can further improve the convenience of adjusting the tension of the brake cable.

[0050] In one embodiment, such as Figure 2 and Figure 7 As shown, the adjustment structure 208 includes an adjustment part 2081 and a connecting part 2082. The adjustment part 2081 is rotatably inserted into the grip section 203, with one end of the adjustment part 2081 protruding from the end of the grip section 203. The connecting part 2082 is disposed in the grip section 203 and sleeved on the outside of the adjustment part 2081. The connecting part 2082 is threadedly connected to the adjustment part 2081 and fixedly connected to the adjustment section 207. The adjustment part 2081 is adapted to rotate itself to drive the connecting part 2082 to move along the axial direction. The overall design of the adjustment structure 208 is simple and reliable. The operator can conveniently and quickly adjust the position of the adjustment section 207 by rotating the adjustment part 2081, thereby achieving the effect of changing the tension of the cable at the grip section 203.

[0051] Specifically, such as Figure 7As shown, in order to facilitate the connection between the connecting part 2082 and the adjusting section 207, the adjusting structure 208 also includes a connecting member 2083. The connecting part 2082 and the adjusting section 207 are connected by the connecting member 2083. The adjusting part 2081 has at least one threaded rod. The threaded rod of the adjusting part 2081 passes through the connecting part 2082 and the connecting member 2083 respectively, and the threaded rod of the adjusting part 2081 is threadedly engaged with both the connecting part 2082 and the connecting member 2083. At this time, rotating the adjusting part 2081 can more reliably drive the adjusting section 207 to move.

[0054] In this embodiment, the operating machinery includes excavators, loaders, cranes, rotary drilling rigs, etc., as long as the braking control device or braking system of this embodiment can be used.

[0055] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
