[0037] In order to make the technical problems, technical solutions and beneficial effects solved by the present utility model more clearly understood, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0038] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "longitudinal", "radial", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model. In the description of the present utility model, unless otherwise specified, the meaning of "a plurality" is two or more.

[0039] In the description of the present utility model, it should be noted that unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0040] Such as Figure 1 And Figure 2As shown in the figure, an embodiment of the present utility model provides a vehicle caliper, which includes a caliper body 1 and an air flow driving member 21; a rotating cavity 11 communicating with the outside is provided on the caliper body 1, and an air outlet channel 12 communicating with the rotating cavity 11; the air flow driving member 21 is installed in the rotating cavity 11 to drive outside air to blow towards a target cooling area through the air outlet channel 12. Wherein, at least one end of the air outlet channel 12 far from the rotating cavity 11 is oppositely arranged to the target cooling area; and this target cooling area can be the brake pad 3 or other positions in the vehicle brake. The brake pad 3 can be installed on the caliper body 1. Thus, the outside air can be communicated with the target cooling area provided on the caliper body 1 through the rotating cavity 11 and the air outlet channel 12. Furthermore, when the air flow driving member 21 operates, it can drive the outside air to form a fixed and fast air flow blowing towards the target cooling area through the air outlet channel 12. During the above air flow process, the air outlet channel 12 can accurately direct the air flow to the target cooling area, and thus accurate air cooling and heat dissipation can be achieved, and high heat dissipation efficiency can be achieved without adding external structures.

[0041] In one embodiment, as Figure 1 、 Figure 2 and Figure 5 shown, an air suction channel 13 is further provided on the caliper body 1, and the rotating cavity 11 communicates with the outside through the air suction channel 13. In this embodiment, outside air enters the rotating cavity 11 through the air suction channel 13 and then blows towards the target cooling area through the air outlet channel 12. Further, the air suction channel 13 includes an air suction bend 131 communicating with the rotating cavity 11 and a plurality of air suction holes 132 connected to one end of the air suction bend 131 far from the rotating cavity 11; the plurality of air suction holes 132 are arranged at intervals on the caliper body 1 and communicate with the outside. Thus, after the outside air is sucked in from the plurality of air suction holes 132 and gathered to the air suction bend 131, it then enters the rotating cavity 11, and it is easier to form a fixed and fast air flow, further improving the heat dissipation efficiency.

[0042] In one embodiment, as Figure 1As shown, the caliper body 1 includes two caliper arms 191 and a connecting body 192 connected between the two caliper arms 191; the air suction hole 132 is provided on the connecting body 192; at least a part of the air suction bend 131, the rotary cavity 11 and the air outlet channel 12 are all located on the caliper arm 191. Among them, a brake pad 3 is symmetrically installed on the inner side of each of the two caliper arms 191, and the two brake pads 3 are respectively arranged on opposite sides of the brake disc of the vehicle brake. At this time, when the vehicle brake pedal is depressed, the two brake assemblies 4 of the vehicle caliper will gradually move closer to each other relative to the brake disc, and then approach and clamp the brake disc, and finally play a braking role through the friction between the brake pad 3 and the brake disc. In this embodiment, since the rotary cavity 11 and the air outlet channel 12 are provided on each caliper arm 191; and the air suction bend 131 is connected between the rotary cavity 11 and the air suction hole 132, and the air suction hole 132 is located on the connecting body 192, therefore, at least a part of the air suction bend 131 will be located on the caliper arm 191, and the end of the air suction bend 131 far from the rotary cavity 11 will be connected to the air suction hole 132 located on the connecting body 192. Therefore, the air suction bend 131 may be provided on both the caliper arm 191 and the connecting body 192, but it may also be entirely located on the caliper arm 191, which can be set according to specific requirements and is not limited herein. And, as Figure 1 shown, the air suction hole 132 can be provided at the top of the connecting body 192, which is the position on the caliper body 1 farthest from the brake pad 3 and the brake disc. Therefore, the relative temperature of the air flow inhaled from the air suction hole 132 will be lower, and thus the air cooling efficiency can be improved. However, in the present utility model, the air suction hole 132 can also be provided at other positions on the caliper body 1, such as on the side or bottom of the connecting body 192, or even on the caliper arm 191, which is not limited herein.

[0043] Further, in the air suction channel 13 and the air outlet channel 12 communicating with the same rotary cavity 11, the outlet of the air suction channel 13 and the inlet of the air outlet channel 12 are respectively provided on opposite sides of the air flow driving member 21. In this way, when the air flow driving member 21 is the fan blade of a fan, the fan blade rotates, and it can more easily drive the air flow entering the rotary cavity 11 from the air suction channel 13 to enter the air outlet channel 12 and flow to the target cooling area.

[0044] In one embodiment, the air outlet channel 12 is inclined with respect to the caliper body 1, and the air outlet channel 12 is arranged towards the target cooling area. That is, in this embodiment, the air outlet channel 12 is an inclined air hole arranged towards the target cooling area. In this way, the air flow can be accurately guided from the rotary cavity 11 to the target cooling area.

[0045] In the vehicle caliper of the above-mentioned embodiment of the present utility model, the air flow driving member 21 is installed in the rotary cavity 11 of the caliper body 1. The air flow driving member 21 can drive the air flow to blow through the air outlet channel 12 towards the target cooling area arranged opposite to the air outlet channel 12, thereby precisely dissipating heat from the target cooling area. In the present utility model, since the air flow driving member 21 only needs to drive the air flow to blow through the air outlet channel 12 towards the target cooling area without large-scale ventilation for temperature reduction, therefore, the air flow velocity is relatively fast, and the air flow can be precisely guided to the position of the target cooling area, realizing precise air-cooled heat dissipation for the target cooling area and improving the heat dissipation efficiency; moreover, since the present utility model sets the rotary cavity 11 on the caliper body 1 to integrally install the air flow driving member 21, it not only has a simple and compact structure, but also reduces the self-weight of the caliper body 1, realizing lightweight design.

[0046] In one embodiment, as Figure 4 shown, the air flow driving member 21 is a fan blade; the cavity volume of the air outlet cavity in the rotary cavity 11 is smaller than the cavity volume of the air suction cavity; the air outlet cavity refers to the cavity located on the side of the fan blade facing the air outlet channel 12; the air suction cavity refers to the cavity located on the side of the fan blade facing the air suction channel 13. That is to say, when the air flow driving member 21 is a fan blade, the fan blade 21 is eccentrically arranged in the rotary cavity 11, and the position of the fan blade 21 facing the air outlet channel 12 is deviated. Taking Figure 4 the fan blade in the left rotary cavity 11 as an example, the fan blade is eccentrically arranged in the left rotary cavity 11 towards the right air outlet channel 12. Thus, when the fan blade rotates clockwise, since the air suction cavity on the left side of the fan blade in the rotary cavity 11 is larger, therefore, when the fan blade rotates, it can bring the air in the larger air suction cavity into the narrower air outlet cavity on the right side. At this time, the cavity volume through which the air flow passes gradually becomes narrower, so the air flow velocity will gradually increase. Furthermore, at the position in the air outlet cavity opposite to the air outlet channel 12, the air flow velocity will increase to be able to quickly pass through the air outlet channel 12 and be squeezed out to the brake pad 3, thereby forming a fixed air flow direction and improving the air flow velocity.

[0047] In one embodiment, as Figure 5 shown, the vehicle caliper further includes a driving assembly 22 installed on the caliper body 1. The driving assembly 22 is connected to the air flow driving member 21 to drive the air flow driving member 21 to drive the outside air to blow through the air outlet channel 12 towards the target cooling area. For example, when the air flow driving member 21 is a fan, the driving assembly 22 can drive the fan blade 21 to rotate, so that the outside air enters the rotary cavity 11 and blows through the air outlet channel 12 towards the target cooling area (such as the brake pad 3) for heat dissipation, improving the heat dissipation efficiency.

[0048] In one embodiment, the driving assembly 22 includes a motor connected to the air flow driving member 21. That is, in this embodiment, the driving assembly 22 may include, but is not limited to, a motor. Thus, when it is necessary to cool the brake pads 3 and the brake disc in the target cooling area, the driving assembly 22 can directly drive the air flow driving member 21 (such as a fan blade) to rotate, and then drive the outside air to blow to the target cooling area through the rotary cavity 11 and the air outlet channel 12.

[0049] In one embodiment, the driving assembly 22 includes a synchronizing member 221 and a transmission assembly; the transmission assembly is connected between the synchronizing member 221 and the air flow driving member 21; one end of the synchronizing member 221 away from the transmission assembly is connected to the brake assembly 4; the synchronizing member 222 is used to drive the transmission assembly to move towards the brake disc under the drive of the brake assembly 4; the transmission assembly is used to drive the air flow driving member 21 to rotate by the frictional force of the brake disc when it moves to fit with the brake disc. That is, the brake assembly 4 can drive the brake pads 3 and the synchronizing member 221 to move towards the brake disc synchronously. At this time, since the synchronizing member 221 is connected to the transmission assembly, when the brake assembly 4 drives the synchronizing member 221 to move towards the brake disc, the synchronizing member 221 will also drive the transmission assembly to move towards the brake disc synchronously; after the transmission assembly moves to fit with the brake disc, a frictional force is generated between the transmission assembly and the brake disc. Then, the transmission assembly transmits the frictional force of the brake disc to the air flow driving member 21, so as to drive the air flow driving member 21 to rotate by the frictional force of the brake disc, and then drive the outside air to blow to the target cooling area through the air outlet channel 12.

[0050] Further, as Figure 1 、 Figure 5 and Figure 6As shown, the transmission assembly includes a drive box 222, a follower wheel 223, a first bevel gear 224, a second bevel gear 225, a multi-faceted rod 226, a spring 227, and a rotating shaft 228 rotatably mounted on the caliper body 1; a synchronizer 221 is connected to the drive box 222. Specifically, the synchronizer 221 is fixedly connected between the drive box 222 and a brake assembly 4 for driving the brake pad 3 to move; the first bevel gear 224 and the second bevel gear 225 are both rotatably mounted on the drive box 222; the first bevel gear 224 is coaxially and fixedly connected to the follower wheel 223; the first bevel gear 224 meshes with the second bevel gear 225; one end of the rotating shaft 228 is provided with a sliding hole 229 adapted to the multi-faceted rod 226, and the air flow driving member 21 is mounted at the end of the rotating shaft 228 away from the sliding hole 229; the spring 227 is mounted in the sliding hole 229; one end of the multi-faceted rod 226 is fixedly connected to the second bevel gear 225, and the other end of the multi-faceted rod 226 is slidably inserted into the sliding hole 229 and presses against the spring 227; the second bevel gear 225 is coaxially arranged with the rotating shaft 228.

[0051] In this embodiment, as Figure 1 shown, when stepping on the brake pedal to brake, the brake assembly 4 drives the brake pad 3 to move towards the brake disc. At this time, the synchronizer 221 (the synchronizer 221 can be a synchronizing plate) fixedly connected to the brake assembly 4 will move synchronously towards the brake disc following the brake assembly 4. Thus, the drive box 222 fixedly connected to the synchronizer 221 will move synchronously towards the brake disc; it can be understood that the follower wheel 223 and the brake pad 3 are both arranged opposite to the brake disc. Therefore, as Figure 5 shown, when the brake pad 3 contacts the brake disc, the follower wheel 223 also fits against the side wall of the brake disc. At this time, the rotation of the brake disc will drive the follower wheel 223 to rotate. Then, the follower wheel 223 will drive the first bevel gear 224 to rotate. Furthermore, since the multi-faceted rod 226 is inserted into the sliding hole 229 to limit the circumferential rotational freedom between the multi-faceted rod 226 and the rotating shaft 228, therefore, the meshing of the first bevel gear 224 and the second bevel gear 225 can drive the multi-faceted rod 226 and the rotating shaft 228 to rotate synchronously, so that the air flow driving member 21 rotates, accelerating the air circulation to play a heat dissipation role. And in this embodiment, braking and heat dissipation can be carried out simultaneously, and the brake disc can be used as a power source to drive the follower wheel 223 etc. to drive the air flow driving member 21 to rotate, without setting other power sources, saving costs. Also, during normal driving, the brake pad 3 does not contact the brake disc and generate friction, and there is no need for heat dissipation. At this time, the follower wheel 223 also does not contact the brake disc, reducing wear and noise, etc.

[0052] Understandably, the multi-faceted rod 226 is a long rod with a multi-faceted column shape, such as a square rod, a triangular prism rod, a hexagonal prism rod, etc. The number of edges of the multi-faceted rod 226 is not limited here. The shape of the sliding hole 229 is correspondingly set according to the multi-faceted column, so as to limit the circumferential rotational freedom between the multi-faceted rod 226 and the rotating shaft 228 through the insertion connection between the multi-faceted rod 226 and the sliding hole 229. Among them, during the process of the drive box 222 moving outward towards the brake disc, the multi-faceted rod 226 slides relative to the rotating shaft 228 under the compressive elastic force of the spring 227, so that the distance between the multi-faceted rod 226 and the air flow driving member 21 increases. However, the multi-faceted rod 226 is always located in the sliding hole 229 under the action of the square rod of the second cone pulley 225. Therefore, it can continuously drive the rotating shaft 228 to rotate. When the brake pads 3 are tightly attached to the brake disc for braking by friction, the multi-faceted rod 226 can also gradually approach the air flow driving member 21 when the follower wheel 223 is tightly attached to the brake disc, so as to adapt to the fitting brake position and clamping degree between the brake pads 3 and the brake disc, so that the follower wheel 223 can be easily driven to rotate, but will not be pressed too tightly on the brake disc, avoiding damage to the internal components of the drive box 222.

[0053] In one embodiment, the caliper body 1 further includes a liquid cooling mechanism 17 installed on the caliper body 1 and used for liquid cooling of the target cooling area. In this embodiment, the liquid cooling mechanism 17 is installed on the caliper body 1. Thus, when it is necessary to cool the brake pads 3 and the brake disc in the target cooling area, the above-mentioned liquid cooling mechanism 17 can be directly operated to cool the target cooling area. For example, the liquid cooling mechanism 17 can spray coolant into the target cooling area, and then cool the target coolant through the sprayed coolant, thereby realizing the liquid cooling of the target cooling area; or, the liquid cooling mechanism 17 can spray coolant into the rotary cavity 11. Then, while the vehicle caliper drives the outside air to pass through the rotary cavity 11 and the air outlet channel 12 and blow towards the target cooling area through the air flow driving member 21 arranged in the rotary cavity 11, it can also carry the coolant sprayed into the rotary cavity 11 to jointly cool the target cooling area, thereby realizing the simultaneous air cooling and liquid cooling of the target cooling area.

[0054] In one embodiment, the liquid cooling mechanism 17 includes a liquid outlet passage 171 communicating with the rotary cavity 11 and a liquid cooling driving assembly connected to the liquid outlet passage 171. The liquid cooling driving assembly is configured to drive the coolant to be sprayed into the rotary cavity 11 through the liquid outlet passage 171. That is, in this embodiment, the liquid cooling mechanism 17 does not directly spray the coolant onto the target cooling area, but sprays the coolant into the rotary cavity 11 through the liquid outlet passage 171, so that the coolant can follow the air flow and act on the target cooling area through the air outlet passage 12 from the rotary cavity 11, thereby realizing air cooling and liquid cooling of the target cooling area simultaneously. It can be understood that the above liquid cooling driving assembly can drive the coolant to enter the rotary cavity 11 from the liquid outlet passage 171. In a specific embodiment, the liquid cooling driving assembly includes, but is not limited to, a driving cylinder or a driving pump. That is, in this embodiment, a driving device such as a driving cylinder or a driving pump can be used to control the coolant to enter the rotary cavity 11 from the liquid outlet passage 171. However, in the present invention, the liquid cooling driving assembly can also be of other structures, as long as it can drive the coolant to enter the rotary cavity 11 from the liquid outlet passage 171.

[0055] In one embodiment, as Figure 4 and Figure 5 shown, the liquid cooling driving assembly includes a pressing plate 172; a driving passage (not shown in the figure) and a conversion cavity 16 are further provided on the caliper body 1; the pressing plate 172 is installed in the conversion cavity 16 and is used to divide the conversion cavity 16 into a braking cavity 161 and a cooling cavity 162; the braking cavity 161 communicates with the driving passage; the cooling cavity 162 communicates with the rotary cavity 11 through the liquid outlet passage 171; a return spring (not shown in the figure) is provided in the cooling cavity 162, and the return spring abuts between the pressing plate 172 and the inner side wall of the cooling cavity 162 away from the pressing plate 172. In this embodiment, on the basis of air cooling, liquid cooling can be added to further improve the heat dissipation efficiency and effectively protect the brake pads 3, etc. In this embodiment, since the driving passage communicates with the braking cavity 161, when the vehicle brake pedal is depressed, the hydraulic oil can enter the braking cavity 161 through the driving passage ( Figure 3In the brake chamber 161 located on the left side, the pressing plate 172 is further pushed inward. At this time, the brake chamber 161 becomes larger, and the cooling chamber 162 becomes smaller under the extrusion of the pressing plate 172. Then, the coolant (such as water, etc.) filled inside the cooling chamber 162 is extruded out from the liquid outlet channel 171 communicating with the cooling chamber 162, so that the coolant enters the rotating chamber 11 from the outlet of the liquid outlet channel 171. Further, under the action of the continuously operating air flow driving member 21 (such as a continuously rotating fan blade), the coolant extruded into the rotating chamber 11 will be broken up into fine droplets or water mist, and then blown towards the brake pad 3 through the air outlet channel 12, thereby simultaneously realizing liquid cooling and air cooling of the brake pad 3. At this time, the coolant in the form of water mist or fine droplets can quickly and evenly absorb the heat of the brake pad 3, achieving a better heat dissipation effect and expanding the heat dissipation area. It can be understood that in this embodiment, after braking, the vehicle brake pedal is released. At this time, the pressure of the hydraulic oil in the brake chamber 161 becomes smaller. Therefore, under the elastic force of the return spring, the pressing plate 172 will be pushed to squeeze the brake chamber 161, so that the hydraulic oil in the brake chamber 161 flows out from the driving channel. Further, the brake chamber 161 gradually becomes smaller, and the corresponding space of the cooling chamber 162 gradually becomes larger. At this time, the pressing plate 172 will gradually return to its original position, that is, as Figure 3 shown in the figure, the pressing plate 172 moves to the left until it fits against the inner wall of the conversion cavity 16.

[0056] It can be understood that when the above-mentioned air flow driving member 21 (such as a fan blade) is eccentrically arranged in the rotating chamber 11, through the settings of the above-mentioned pressing plate 172, conversion cavity 16, liquid outlet channel 171, etc., the method of directional ventilation combined with liquid cooling can be better realized, greatly improving the cooling efficiency and heat dissipation effect. Among them, the outer side wall of the pressing plate 172 is hermetically and fittingly connected with the inner side wall of the conversion cavity 16, and the pressing plate 172 can slide in the conversion cavity 16, but the liquids in the brake chamber 161 and the cooling chamber 162 separated by the pressing plate 172 will not flow into each other. The liquid flowing in the brake chamber 161 is hydraulic oil, while the liquid flowing in the cooling chamber 162 is coolant.

[0057] In one embodiment, as Figure 4 shown, a liquid replenishing channel 18 communicating with the liquid outlet channel 171 is further provided on the caliper body 1; a first one-way valve 181 is provided in the liquid replenishing channel 18, and the first one-way valve 181 is used to control the one-way flow of the coolant in the liquid replenishing channel 18 into the liquid outlet channel 171; a second one-way valve 1711 is provided in the liquid outlet channel 171; the second one-way valve 1711 is used to control the one-way flow of the coolant in the liquid outlet channel 171 into the rotating chamber 11.

[0058] Among them, the liquid outlet channel 171 is also connected to a liquid replenishing channel 18 (when the conversion cavity 16 exists, the liquid replenishing channel 18 can also be directly connected to the cooling cavity 162, and then connected to the liquid outlet channel 171 through the cooling cavity 162). A first one-way valve 181 is provided in the liquid replenishing channel 18 to control that the coolant can only enter the liquid outlet channel 171 (or the cooling cavity 162) unidirectionally from an external liquid storage container through the liquid replenishing channel 18, but the coolant in the liquid outlet channel 171 (or the cooling cavity 162) cannot flow out to the external liquid storage container through the liquid replenishing channel 18; and a second one-way valve 1711 is provided in the liquid outlet channel 171 to control that the coolant can flow unidirectionally from the liquid outlet channel 171 (or from the cooling cavity 162 through the liquid outlet channel 171) into the rotating cavity 11, but cannot flow back from the rotating cavity 11. In this embodiment, after braking is completed, the pressing plate 172 will return to its original position (that is, as shown in Figure 3 ), the pressing plate 172 moves to the left and fits against the inner wall of the conversion cavity 16. At this time, the space corresponding to the cooling cavity 162 gradually becomes larger. Since the first one-way valve 181 is provided in the liquid replenishing channel 18 and the second one-way valve 1711 is provided in the liquid outlet channel 171, at this time, the coolant in the external liquid storage container can be timely sucked into the liquid outlet channel 171 (or the cooling cavity 162) through the liquid replenishing channel 18, so as to ensure the continuity of liquid cooling and facilitate automatic liquid replenishment for the next use.

[0059] Understandably, the position and shape of the liquid replenishing channel 18 can be set according to requirements. For example, in the embodiment shown in Figure 4 , the liquid replenishing channel 18 can be arranged near the brake pad 3. However, in the present invention, as long as the liquid replenishing channel 18 can supply coolant to the cooling cavity 162, its installation position is not limited.

[0060] Understandably, as shown in Figure 4 , the shapes and structures of the first one-way valve 181 and the second one-way valve 1711 can be set according to requirements. For example, both the first one-way valve 181 and the second one-way valve 1711 can include a bucket-shaped ring 1812 and a sealing ball 1811 installed in the bucket-shaped ring 1812. Specifically, in the embodiment shown in Figure 4 , during liquid replenishment, the sealing ball 1811 of the second one-way valve 1711 in the liquid outlet channel 171 will tightly adhere to the bucket-shaped ring 1812 under the action of internal pressure, so as to achieve sealing, preventing external air from entering the cooling cavity 162 from the liquid outlet channel 171, and thus realizing smooth liquid replenishment. When the pressing plate 172 squeezes the cooling cavity 162 to discharge liquid from the liquid outlet channel 171 to the rotating cavity 11, the sealing ball 1811 of the first one-way valve 181 in the liquid replenishing channel 18 is pressed tightly in its corresponding bucket-shaped ring 1812. At this time, the liquid replenishing channel 18 is sealed, and the sealing ball 1811 of the second one-way valve 1711 in the liquid outlet channel 171 is pushed open, realizing smooth liquid discharge.

[0061] The present utility model also provides a vehicle brake, including the above-mentioned vehicle caliper. In the vehicle brake of the above-mentioned embodiment of the present utility model, the air flow driving member 21 of the vehicle caliper is installed in the rotary cavity 11 of the caliper body 1. The air flow driving member 21 can drive the outside air into the rotary cavity 11, and then drive the air flow in the rotary cavity 11 to blow towards the target cooling area through the air outlet channel 12, so as to accurately dissipate heat from the target cooling area. In the present utility model, since the air flow driving member 21 only needs to drive the air flow to blow towards the target cooling area through the air outlet channel 12 without large-scale ventilation and cooling, the air flow velocity is relatively fast, and the air flow can be accurately guided to the position of the target cooling area, realizing accurate air-cooled heat dissipation of the target cooling area and improving the heat dissipation efficiency. Moreover, since the present utility model sets the rotary cavity 11 on the caliper body 1 to integrally install the air flow driving member 21, it not only has a simple and compact structure, but also reduces the self-weight of the caliper body 1, realizing lightweight design.

[0062] In one embodiment, as Figure 3 shown, a sliding cavity 14 is further provided on the caliper body 1; the vehicle brake further includes a brake pad 3 installed on the caliper body 1; the vehicle caliper further includes a brake assembly 4 slidably installed in the sliding cavity 14, and the brake pad 3 is installed on the end face of the brake assembly 4 away from the sliding cavity 14. Understandably, as Figure 1 shown, two sliding cavities 14 are symmetrically provided on the caliper body 1, and a brake assembly 4 is slidably installed in each of the two sliding cavities 14, and a brake pad 3 is installed on each brake assembly 4, and the two brake pads 3 are respectively arranged on opposite sides of the brake disc of the vehicle brake. At this time, when the vehicle brake pedal is depressed, the two brake assemblies 4 will be controlled to push out along the sliding cavity 14, so that the brake pads 3 on both sides of the caliper body 1 gradually approach each other relatively towards the brake disc, and then approach and clamp the brake disc, and finally play a braking role through the friction between the brake pad 3 and the brake disc. Further, one end of at least one of the air outlet channels 12 away from the rotary cavity 11 is arranged opposite to the brake pad 3; at this time, the target cooling area includes the brake pad 3.

[0063] Further, as Figure 3As shown, the brake assembly 4 includes a brake lever 41 and a mounting disc 42 mounted on the brake lever 41; one end of the brake lever 41 away from the mounting disc 42 is slidably inserted into the sliding cavity 14; the brake pads 3 are mounted on the end face of the mounting disc 42 facing away from the brake lever 41. In this embodiment, the brake lever 41 is slidably connected in the sliding cavity 14, and the end of the brake lever 41 is fixedly connected with a mounting disc 42, and the brake pads 3 are mounted on the end face of the mounting disc 42 away from the brake lever 41; furthermore, by the relative sliding between the sliding cavity 14 and the brake lever 41, the brake pads 3 can be pushed closer to or away from the brake disc.

[0064] In one embodiment, as Figure 3 shown, the caliper body 1 is further provided with a transmission oil passage 15 communicating with the sliding cavity 14 to drive the brake assembly 4 and the brake pads 3 to slide along the sliding cavity 14 by the liquid transmitted through the transmission oil passage 15. In this embodiment, a transmission oil passage 15 is provided inside the caliper body 1, and the transmission oil passage 15 communicates with the sliding cavity 14. Thus, when the vehicle brake pedal is depressed, the hydraulic oil will be controlled to enter the sliding cavity 14 through the transmission oil passage 15, so that the brake lever 41 is pushed out by the pressure of the hydraulic oil, and then the brake pads 3 on both sides of the caliper body 1 gradually approach both sides of the brake disc until they clamp the brake disc, and finally the braking effect is achieved through the friction between the brake pads 3 and the brake disc.

[0065] In one embodiment, the drive channel is the transmission oil passage 15. In this embodiment, the transmission oil passage 15 is the drive channel communicating with the brake cavity 161, that is, the transmission oil passage 15 communicates with the sliding cavity 14 and the brake cavity 161 at the same time. Therefore, when the vehicle brake pedal is depressed, while the hydraulic oil enters the sliding cavity 14 through the transmission oil passage 15, it will also synchronously enter the brake cavity 161 ( Figure 3 the brake cavity 161 located on the left side in it), and then the pressing plate 172 is pushed inward. At this time, the brake cavity 161 becomes larger, and the cooling cavity 162 becomes smaller under the extrusion of the pressing plate 172, and then the coolant (such as water, etc.) filled in the cooling cavity 162 is squeezed out from the liquid outlet passage 171 communicating with the cooling cavity 162, so that the coolant enters the rotary cavity 11 from the outlet of the liquid outlet passage 171.

[0066] The present utility model further provides a braking system, including the above-mentioned vehicle brake. In the braking system of the above-mentioned embodiment of the present utility model, the air flow driving member 21 of the vehicle caliper is installed in the rotary cavity 11 of the caliper body 1. The air flow driving member 21 can drive the outside air into the rotary cavity 11, and then drive the air flow in the rotary cavity 11 to blow towards the target cooling area through the air outlet channel 12. In the present utility model, since the air flow driving member 21 only needs to drive the air flow to blow towards the target cooling area through the air outlet channel 12 without large-scale ventilation and cooling, the air flow velocity is relatively fast, and the air flow can be accurately guided to the position of the target cooling area, realizing accurate air-cooled heat dissipation of the target cooling area and improving the heat dissipation efficiency; moreover, since the present utility model sets the rotary cavity 11 on the caliper body 1 to integrally install the air flow driving member 21, it not only has a simple and compact structure, but also reduces the self-weight of the caliper body 1, realizing lightweight design.

[0067] The present utility model further provides a vehicle, including a vehicle body and the above-mentioned braking system. Among them, the braking system is installed on the vehicle body. In the vehicle of the above-mentioned embodiment of the present utility model, the air flow driving member 21 of the vehicle caliper is installed in the rotary cavity 11 of the caliper body 1. The air flow driving member 21 can drive the outside air into the rotary cavity 11, and then drive the air flow in the rotary cavity 11 to blow towards the target cooling area through the air outlet channel 12. In the present utility model, since the air flow driving member 21 only needs to drive the air flow to blow towards the target cooling area through the air outlet channel 12 without large-scale ventilation and cooling, the air flow velocity is relatively fast, and the air flow can be accurately guided to the position of the target cooling area, realizing accurate air-cooled heat dissipation of the target cooling area and improving the heat dissipation efficiency; moreover, since the present utility model sets the rotary cavity 11 on the caliper body 1 to integrally install the air flow driving member 21, it not only has a simple and compact structure, but also reduces the self-weight of the caliper body 1, realizing lightweight design.

[0068] The above are only the preferred embodiments of the present utility model, and are not intended to limit the present utility model. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
