Description

Technical Field

[0001] This utility model relates to the field of brake cables, specifically a sheath structure for a power brake cable. Background Technology

[0002] Power brake cables are key components in modern transportation vehicles used to transmit braking power commands. They transmit electrical energy or signals through internal conductive lines, thereby precisely controlling the start and operation of the braking system and playing an indispensable role in ensuring safe braking of vehicles.

[0003] In practical applications, the power brake cable is connected to the electronic control unit inside the brake and receives electrical signals from the vehicle's brake pedal or related control devices. When the driver presses the brake pedal, the pedal displacement signal is converted into an electrical signal and transmitted to the brake actuator via the power brake cable. The actuator controls the pressure between the brake pads and the brake disc based on the received signal strength and instructions, thereby achieving the effect of vehicle deceleration or braking.

[0004] However, during vehicle operation, the power brake cables are often exposed to a complex and ever-changing external environment. Sharp objects such as stones and sharp metal fragments scattered on the road can easily scratch or damage the surface of the brake cables. Once the surface of the brake cables is damaged, the internal conductive circuits lose effective protection and may experience abnormalities such as short circuits or open circuits, which in turn will cause the brakes to fail to receive and execute braking commands normally. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide a sheath structure for a power brake cable to solve the technical problem that the power brake cable is easily scratched by sharp objects on the road.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a sheath structure for a power brake cable, comprising a sheath and a cable, wherein a core is disposed inside the cable, and a sheath is fitted over the outer wall of the cable, wherein an inner tube, a skeleton, and a support tube are sequentially disposed inside the sheath, multiple sets of protective sleeves are fixed to the outer wall of the sheath, a protective ring is installed inside the protective sleeve, a protective sleeve is disposed between two sets of protective sleeves, and six sets of first protective plates and second protective plates are installed inside the protective sleeve.

[0007] By adopting the above technical solution, the problem that the power brake line of the electric wire and cable is easily scratched by sharp objects on the road is solved. The outer wall of the sleeve is equipped with multiple sets of protective sleeves, which are equidistant. The protective rings made of aluminum alloy inside the protective sleeves are set in the shape of an I-beam. The protective rings protect the sleeve and prevent sharp objects on the road from scratching the sleeve at a horizontal angle. In addition, when a sharp object scratches the sleeve at a vertical angle, the first and second protective plates located inside the protective sleeves protect the internal structure of the sleeve, so that the sharp object will not scratch the internal structure of the sleeve through the protective sleeves.

[0008] The present invention is further configured such that the multiple sets of protective sleeves are arranged at equal intervals, and the protective sleeves are made of polyurethane material.

[0009] Preferably, the protective sleeves arranged at equal intervals can protect the outer wall surface of the sleeve, and when the sleeve is partially bent, there will be no interference between the two sets of adjacent protective sleeves.

[0010] The present invention is further configured such that the inner wall diameter of the sleeve is larger than the outer wall diameter of the cable, and the difference between the inner wall diameter of the sleeve and the outer wall diameter of the cable is within 2 mm.

[0011] Preferably, the sleeve is movably mounted on the cable, making it convenient for personnel to replace the sleeve on the cable regularly.

[0012] The present invention is further configured such that the interior of the skeleton is provided with multiple sets of cavities, and the inner walls of the cavities are arc-shaped.

[0013] Preferably, the cavity can reduce the total weight of the casing, and when the casing undergoes local bending, the cavity can provide space for the deformation of the internal structure of the casing.

[0014] The present invention is further configured such that the protective ring is configured as an I-shape and is made of aluminum alloy.

[0015] Preferably, the I-shaped protective ring can withstand greater external compressive force, thus protecting the outer wall of the casing.

[0016] The present invention is further configured such that the width of the inner wall of the protective ring is greater than the width of the outer wall of the protective ring, and the inner wall of the protective ring is fixed to the outer wall of the support tube.

[0017] Preferably, when an external object compresses the protective ring, the pressure is transmitted to the support tube through the bottom wall of the protective ring. The width of the inner wall of the protective ring is greater than the width of the outer wall of the protective ring, which increases the contact area between the protective ring and the support tube, thereby reducing the compressive force of the protective ring on the support tube per unit area.

[0018] The present invention is further configured such that the multiple sets of first protective plates are arranged at equal intervals, and there is a gap between the two sets of first protective plates.

[0019] Preferably, six sets of first protective plates are arranged around the inside of the protective sleeve, so that multiple sets of first protective plates protect the outer wall of the sleeve.

[0020] The present invention is further configured such that one side of the first protective plate and the second protective plate are provided with a protrusion and a groove, and the size of the groove and the protrusion are matched.

[0021] Preferably, when the sleeve bends, the first and second protective plates inside the protective sleeve are displaced inside the protective sleeve. The first and second protective plates located on the side of the protective sleeve that bends and contracts move closer to each other, and the protrusion on one side of the first protective plate snaps into the groove on one side of the second protective plate, so that the first and second protective plates can protect the protective sleeve between the two sets of protective sleeves.

[0022] In summary, the present invention has the following main advantages:

[0023] 1. This utility model solves the problem that power brake cables are easily scratched by sharp objects on the road by setting up a sleeve, cable, protective sleeve, first protective plate, second protective plate, protective sleeve and protective ring. The outer wall of the sleeve is provided with multiple sets of protective sleeves, which are equidistant. The protective ring made of aluminum alloy inside the protective sleeve is set as an I-shaped structure. The protective ring protects the sleeve and prevents sharp objects on the road from scratching the sleeve at a horizontal angle. In addition, when a sharp object scratches the sleeve at a vertical angle, the first and second protective plates located inside the protective sleeve protect the internal structure of the sleeve, so that the sharp object will not scratch the internal structure of the sleeve through the protective sleeve.

[0024] 2. This utility model, by setting a first protective plate, a second protective plate, a groove, and a protrusion, allows the cable to be laid with a partial bend. When the cable is partially bent, the sleeve wrapped around the cable also bends at the bend. When the sleeve bends, the first and second protective plates inside the protective sleeve are displaced. The first and second protective plates located on the side of the protective sleeve that is bent and contracted move closer to each other. The protrusion on one side of the first protective plate engages with the groove on one side of the second protective plate, so that the first and second protective plates can protect the protective sleeve between the two sets of protective sleeves.

[0033] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0034] The embodiments of this utility model will be described below based on its overall structure.

[0035] First embodiment:

[0036] Please see Figure 1 — Figure 5 The system includes a sleeve 1 and a cable 2. The cable 2 contains a wire core 201. The sleeve 1 is fitted over the outer wall of the cable 2. Inside the sleeve 1, an inner tube 101, a frame 102, and a support tube 104 are sequentially arranged. Multiple sets of protective sleeves 4 are fixed to the outer wall of the sleeve 1. Protective rings 401 are installed inside the protective sleeves 4. A protective sleeve 3 is placed between two sets of protective sleeves 4. Six sets of first protective plates 5 and second protective plates 501 are installed inside the protective sleeve 3. This system solves the problem that power brake cables are easily punctured by sharp objects on the road. To address the issue, the outer wall of the sleeve 1 is provided with multiple sets of protective sleeves 4, which are equidistantly arranged. The protective rings 401 made of aluminum alloy inside the protective sleeves 4 are set in an I-shape. The protective rings 401 protect the sleeve 1 and prevent sharp objects on the road from scratching the sleeve 1 at a horizontal angle. In addition, when a sharp object scratches the sleeve 1 at a vertical angle, the first protective plate 5 and the second protective plate 501 located inside the protective sleeve 3 protect the internal structure of the sleeve 1, so that the sharp object will not scratch the internal structure of the sleeve 1 through the protective sleeve 3.

[0037] For details regarding the above embodiments, please refer to [link / reference]. Figure 1 Multiple sets of protective sleeves 4 are set at equal intervals. The protective sleeves 4 are made of polyurethane. The equally spaced protective sleeves 4 can protect the outer wall surface of the sleeve 1. When the sleeve 1 is partially bent, there will be no interference between two adjacent sets of protective sleeves 4.

[0038] For details regarding the above embodiments, please refer to [link / reference]. Figure 2 The inner diameter of the sleeve 1 is larger than the outer diameter of the cable 2, and the difference between the inner diameter of the sleeve 1 and the outer diameter of the cable 2 is within 2mm. The sleeve 1 is movably fitted on the cable 2, which facilitates the replacement of the sleeve 1 on the cable 2 by personnel on a regular basis.

[0039] For details regarding the above embodiments, please refer to [link / reference]. Figure 2 The skeleton 102 has multiple cavities 103 inside, and the inner wall of the cavity 103 is arc-shaped. The cavity 103 can reduce the total weight of the sleeve 1, and when the sleeve 1 is partially bent, the cavity 103 can provide space for the deformation of the internal structure of the sleeve 1.

[0040] For details regarding the above embodiments, please refer to [link / reference]. Figure 4 The protective ring 401 is designed in the shape of an I-beam and is made of aluminum alloy. The I-beam protective ring 401 can withstand large external compressive forces, thus protecting the outer wall of the sleeve 1.

[0041] For details regarding the above embodiments, please refer to [link / reference]. Figure 4 The inner wall width of the protective ring 401 is greater than the outer wall width of the protective ring 401, and the inner wall of the protective ring 401 is fixed to the outer wall of the support tube 104. When an external object squeezes the protective ring 401, the pressure is transmitted to the support tube 104 through the bottom wall. The inner wall width of the protective ring 401 is greater than the outer wall width of the protective ring 401, which increases the contact area between the protective ring 401 and the support tube 104, thereby reducing the squeezing force of the protective ring 401 on the support tube 104 per unit area.

[0042] For details regarding the above embodiments, please refer to [link / reference]. Figure 5 Multiple sets of first protective plates 5 are arranged at equal intervals, and there are gaps between two sets of first protective plates 5. Six sets of first protective plates 5 are arranged around the inside of the protective sleeve 3, so that multiple sets of first protective plates 5 protect the outer wall of the sleeve 1.

[0043] For details regarding the above embodiments, please refer to [link / reference]. Figure 5The first protective plate 5 and the second protective plate 501 are provided with a protrusion 503 and a groove 502 on one side, and the groove 502 and the protrusion 503 are matched in size. When the sleeve 1 bends, the first protective plate 5 and the second protective plate 501 inside the protective sleeve 3 are displaced inside the protective sleeve 3. The first protective plate 5 and the second protective plate 501 located on the side of the protective sleeve 3 that bends and contracts are close to each other. The protrusion 503 on the side of the first protective plate 5 is engaged in the groove 502 on the side of the second protective plate 501, so that the first protective plate 5 and the second protective plate 501 can protect the protective sleeve 3 between the two sets of protective sleeves 4.

[0044] Second embodiment:

[0045] Please see Figure 6 The protective sleeve 3 has multiple sets of honeycomb holes 301 inside, and the porosity inside the protective sleeve 3 is 40%. When the cable 2 is bent and laid inside the car, the sleeve 1 wrapped around the outer wall of the cable 2 bends locally along with the cable 2. During the bending process of the sleeve 1, the first protective plate 5 and the second protective plate 501 inside the protective sleeve 3 are displaced inside the protective sleeve 3, so that the first protective plate 5 and the second protective plate 501 squeeze the protective sleeve 3 inside the protective sleeve 3. The honeycomb holes 301 inside the protective sleeve 3 provide sufficient space for the displacement of the first protective plate 5 and the second protective plate 501.

[0046] In practical operation: the sleeve 1 is fitted onto the outer wall of the cable 2. The inner tube 1 and the support tube 104 inside the sleeve 1 are both made of polyurethane, while the skeleton 102, which provides structural support and shape protection for the inside of the sleeve 1, is made of polyester fiber. If the cable 2 is laid along the direction of vehicle travel, the protective ring 401 made of aluminum alloy inside the protective sleeve 4 protects the sleeve 1 during vehicle travel, preventing sharp objects on the road from scratching the sleeve 1 at a lateral angle. The protective ring 401 is set in an I-shape, and the inner wall of the protective ring 401 is fixedly set on the outer wall of the support tube 104. The I-shaped protective ring 401 can withstand large external compressive forces. In addition, when a sharp object scratches the sleeve 1 at a longitudinal angle, the first protective plate 5 and the second protective plate 501 located inside the protective sleeve 3 protect the internal structure of the sleeve 1. The first protective plate 5 and the second protective plate 501 are made of aluminum alloy, so that sharp objects will not scratch the internal structure of the sleeve 1 through the protective sleeve 3.
