[0038] Embodiment 1

[0039] like Figure 1 As shown, the first aspect of the present application provides a brake device, which includes a brake disc and a brake pad (not shown in the figure), including a caliper 1, the caliper 1 has a first bracket 11 and a second bracket 12 that are spaced and relatively arranged, and a receiving space 13 is formed between the first bracket 11 and the second bracket 12, and the receiving space 13 is used to receive the brake disc and the brake pad, and a first surface 111 of the first bracket 11 on a side away from the second bracket 12, and / or a second surface 121 of the second bracket 12 on a side away from the first bracket 11 is provided with a connecting structure 14, and the connecting structure 14 is used to connect the counterweight component 2.

[0040] Specifically, the caliper 1 body of the caliper 1 has a first bracket 11 and a second bracket 12 that are spaced apart and arranged opposite to each other, and an accommodating space 13 is formed between the first bracket 11 and the second bracket 12. In the brake device, the brake disc and the brake pad in the brake assembly are placed in the accommodating space 13. When the brake device is installed on the tire of the car, the caliper 1 body and the tire are in a parallel state, so that one of the two brackets of the caliper 1 body will inevitably be close to the car body, while the other is away from the car body.

[0041] In one embodiment, a bracket close to the vehicle body is provided with a piston, which is connected to the brake oil circuit of the vehicle, while a bracket away from the vehicle body is not provided with a piston. In another embodiment, two brackets of the caliper 1 body are provided with pistons, one each, or more. The function of the piston is to drive the piston to move when the brake oil circuit is connected, thereby pushing the brake pad close to the brake disc surface to achieve braking. The present application does not limit the specific setting of the caliper 1.

[0042] The connection structure 14 can be a connection piece such as a boss 141 or a threaded hole, etc., which is arranged on the first surface 111 and / or the second surface 121 of the caliper 1. The connection structure 14 can be integrally formed with the first bracket 11 and / or the second bracket 12 of the caliper 1, or can be connected in other connection methods, which are not limited to the specific ones. In addition, the connection structure 14 provided by the present application has a simple structure, is easy to manufacture, saves costs, and provides users with a maintenance means for reducing noise and improving the brake device.

[0043] The specific setting position and quantity of the connection structure 14 on the first surface 111 or the second surface 121 are not limited. Preferably, in order to ensure the beauty or easy production and manufacturing of the caliper 1, it is possible to consider setting the connection structure 14 in the middle of the first surface 111 or the second surface 121 or to select a symmetrical setting form with the middle of the two as the symmetry center. The specific setting position is not limited. And the connection structure 14 can be selected to be set only on the first surface 111 or only on the second surface 121 in the caliper 1. When both surfaces are set at the same time, the corresponding setting positions of the connection structures 14 on the two surfaces should be kept as corresponding as possible, so as to facilitate production and manufacturing and the beauty of the product, and also to facilitate the overall balance and center of gravity stability of the caliper 1.

[0044] It should be noted that, due to the structural limitation of the automobile itself, the first surface 111 or the second surface 121 may be close to the inside or outside of the automobile body. In order to facilitate the installation of the connection structure 14 when it is connected to the counterweight component 2, it is possible to consider setting the connection structure 14 on the side close to the outside of the automobile body so that it can be installed next to the vehicle. When the connection structure 14 is set close to the inside of the automobile body, the installation operation can be performed by lifting the vehicle body or lowering it under the vehicle.

[0045] A first aspect of the present application provides a brake device, which is additionally provided with a connecting structure 14. The caliper 1 has a first bracket 11 and a second bracket 12 that are spaced and arranged opposite to each other, and a receiving space 13 is formed between the first bracket 11 and the second bracket 12, and the receiving space 13 is used to receive a brake disc and a brake pad, and a first surface 111 of the first bracket 11 on a side away from the second bracket 12, and / or a second surface 121 of the second bracket 12 on a side away from the first bracket 11 is provided with a connecting structure 14, and the connecting structure 14 is used to connect the counterweight component 2. The brake device is composed of a brake disc, a brake pad and a caliper 1. During the use of the car, the wear of the brake disc or the brake pad increases, resulting in a decrease in the overall weight of the brake device. The vibration frequency of the brake device with a reduced weight increases during the operation of the car, thereby causing a high-frequency noise problem. The present application provides a noise reduction maintenance method for the brake device through a connection structure 14 on the caliper 1 for connecting a counterweight component 2. When the brake device of the car has a noise problem, the user can use the counterweight component 2 to counterweight the caliper 1 through the connection structure 14 set on the caliper 1, thereby compensating for the weight lost in the brake device due to the wear of the brake disc or the brake pad, so as to ensure that the overall weight of the brake device is maintained at an appropriate level, and ensure that the brake device is at a normal vibration frequency during the operation of the car, thereby avoiding the increase in the vibration frequency after the weight is reduced and the noise generated by the increased tone, thereby playing a role in noise reduction. Through the application of the utility model, the problem that the brake device with a reduced overall weight will generate high-frequency noise during the driving of the car as the wear of the brake disc or the brake pad increases in the prior art is solved, which affects the driving experience of the user.

[0046] like Figure 1 As shown, in some embodiments, there are an even number of connection structures 14, and the even number of connection structures 14 are all arranged on the first surface 111, and are spaced apart and symmetrically arranged relative to the middle of the first surface 111; or, the even number of connection structures 14 are all arranged on the second surface 121, and are spaced apart and symmetrically arranged relative to the middle of the second surface 121; or, half of the even number of connection structures 14 are arranged in the middle of the first surface 111, and the other half are arranged in the middle of the second surface 121; or, half of the even number of connection structures 14 are symmetrically arranged relative to the middle of the first surface 111, and the other half are symmetrically arranged relative to the middle of the second surface 121.

[0047] Specifically, the present application provides four embodiments when the number of the connection structures 14 is an even number, specifically:

[0048] An even number of connection structures 14 are disposed on the first surface 111 and are spaced apart and symmetrically disposed relative to the middle of the first surface 111;

[0049] An even number of connection structures 14 are disposed on the second surface 121 and are spaced apart and symmetrically disposed relative to the middle of the second surface 121;

[0050] It should be noted that, due to the structural limitation of the automobile itself, the first surface 111 or the second surface 121 may be close to the inside or outside of the automobile body. In order to facilitate the installation of the connection structure 14 when it is connected to the counterweight component 2, it is possible to consider setting the connection structure 14 on the side close to the outside of the automobile body so that it can be installed next to the vehicle. When the connection structure 14 is set close to the inside of the automobile body, the installation operation can be performed by lifting the vehicle body or lowering it under the vehicle.

[0051] Half of the even-numbered connection structures 14 are arranged at intervals in the middle of the first surface 111 , and the other half are arranged at intervals in the middle of the second surface 121 ;

[0052] Half of the even-numbered connection structures 14 are symmetrically arranged relative to the middle of the first surface 111 , and the other half are symmetrically arranged relative to the middle of the second surface 121 .

[0053] In both embodiments, the configuration is based on the overall balance and center of gravity stability of the caliper 1. More position options are provided for installing the counterweight component 2. When there are four connecting structures 14, in one case, two connecting structures 14 are spaced apart in the middle of the first surface 111, and the other two connecting structures 14 are spaced apart in the middle of the second surface 121. When installing the counterweight component 2, one counterweight component 2 may be installed on each of the first surface 111 and the second surface 121, or two may be installed on each, to ensure the overall balance and center of gravity stability of the caliper 1. In another case, two connecting structures 14 are symmetrically arranged relative to the middle of the first surface 111, and the other two are symmetrically arranged relative to the middle of the second surface 121. The installation positions also need to follow the principle of balanced symmetry.

[0054] like Figure 2 As shown, in some embodiments, there are an odd number of connecting structures 14, and the odd number of connecting structures 14 are all arranged on the first surface 111, and any connecting structure 14 is located in the middle of the first surface 111, and the remaining connecting structures 14 are spaced and symmetrically arranged relative to the middle of the first surface 111; or, an odd number of connecting structures 14 are all arranged on the second surface 121, and any connecting structure 14 is connected to the middle of the second surface 121, and the remaining connecting structures 14 are spaced and symmetrically arranged relative to the middle of the second surface 121.

[0055] Specifically, in order to prevent the weight component 2 from affecting the center of gravity of the caliper 1, ensure the stable operation of the caliper 1 in the brake device, and increase the weight of the brake device to achieve noise reduction, the present application can also set an odd number of weight components 2. In this embodiment, an odd number of connecting structures 14 are all set on the first surface 111, and any connecting structure 14 is located in the middle of the first surface 111, and the other connecting structures 14 are spaced and symmetrically arranged relative to the middle of the first surface 111; or, an odd number of connecting structures 14 are all set on the second surface 121, and any connecting structure 14 is connected to the middle of the second surface 121, and the other connecting structures 14 are spaced and symmetrically arranged relative to the middle of the second surface 121. And when it is necessary to slightly adjust the weight of the weight component 2, it can be achieved by only disassembling or installing the weight component 2 in the middle, which simplifies the operation process required for weight balancing.

[0056] In some embodiments, the connection structure 14 is a boss 141 , and the boss 141 protrudes from the first surface 111 and / or the second surface 121 along a direction away from the caliper 1 .

[0057] Specifically, the connection structure 14 provided by the present application has a simple structure and is easy to manufacture and assemble, thereby improving the working efficiency when balancing weights through the counterweight component 2. The boss 141 protrudes from the first surface 111 and / or the second surface 121 in a direction away from the caliper 1, which facilitates the operator to install the counterweight component 2 on the boss 141. In addition, the boss 141 can be integrally formed with the caliper 1 body, so that the boss 141 is firmly connected to the first surface 111 and / or the second surface 121, saving additional connection costs.

[0058] The counterweight component 2 and the boss 141 can be connected by pin holes, screw holes, connecting rods, etc., so that counterweighting can be performed when noise problems occur in the vehicle to solve the corresponding problems.

[0059] In some embodiments, the boss 141 defines a first threaded hole 142 .

[0060] Specifically, in order to facilitate the mating connection between the boss 141 and the mating component, in one embodiment, the boss 141 is provided with a first threaded hole 142, and the weight component 2 may be provided with a corresponding threaded hole, the threaded hole of the weight component 2 and the first threaded hole 142 having the same aperture and being arranged opposite to each other, so that the weight component 2 and the boss 141 can be detachably connected by passing a bolt through the first threaded hole 142 and the threaded hole of the weight component 2. In another embodiment, the weight component 2 may be provided with a threaded rod corresponding to the first threaded hole 142, and the detachable connection between the weight component 2 and the boss 141 is achieved by the mating of the two.

[0061] And in the case where the boss 141 is provided with a first threaded hole 142, there can be multiple counterweight components 2, and the multiple counterweight components 2 are all provided with threaded holes with the same aperture as the first threaded hole 142 and arranged relatively to each other, and are connected by passing bolts through the above-mentioned multiple threaded holes, and the weight of the counterweight can be adjusted by the number of counterweight components 2. When the weight required for counterweighting is large, the boss 141 and multiple counterweight components 2 are passed through bolts. When the weight required for counterweighting is small, the number of assembled counterweight components 2 is appropriately reduced.

[0062] In some embodiments, the boss 141 is stepped.

[0063] Specifically, in order to achieve weight adjustment of the counterweight component 2, the present application can realize the matching connection of multiple counterweight components 2 through the stepped boss 141. Threads are set on each step of the stepped boss 141, and the connection is achieved by matching with threaded holes of different apertures of multiple counterweight components 2. The stepped boss 141 makes the weight of the counterweight component 2 connected to each step different. The weight range of the counterweight is adjusted as needed, and the number of steps of the boss 141, the size of the counterweight component 2, or the number of counterweight components 2 installed are selected without specific limitation.

[0064] Embodiment 2

[0065] A second aspect of the present application provides a brake noise reduction assembly, including a brake device and a weight component 2, wherein the weight component 2 is cooperatively connected to a connection structure 14 of the brake device.

[0066] Specifically, the specific structure of the brake device refers to the first embodiment, which will not be described in detail here.

[0067] Specifically, the function of the counterweight component 2 is to increase the weight of the caliper 1. Since the caliper 1 and brake components such as the brake disc and brake pad together constitute the brake device, the counterweight component 2 actually also adds weight to the brake device. During the use of the car, as the degree of wear of the brake disc increases, the overall weight of the brake device decreases. The brake device with reduced weight has a higher vibration frequency during the operation of the car, thereby causing high-frequency noise problems. The counterweight component 2 compensates for the weight loss of the brake device due to the wear of the brake disc or brake pad, thereby reducing the vibration frequency of the brake device and the tone of the sound generated, thereby playing a role in noise reduction.

[0068] The weight component 2 and the connection structure 14 can be detachably connected, so that when the vehicle has no noise problem, the weight component 2 is not installed. Once the brake disc or brake pad and the brake device become lighter and noise occurs due to long-term wear, the weight component 2 is connected through the connection structure 14 to adjust the weight. In addition, a variety of weight components 2 of different weights can be configured to meet the needs of solving noise problems of different degrees. Weight components 2 of different materials can also be configured, and the specific weight balancing method is not limited. It should also be noted that the structure or shape of the weight component 2 can be adjusted according to the connection structure 14 of the caliper 1 and the overall structure or external contour of the caliper 1, so that the weight component 2 can achieve noise reduction while keeping the caliper 1 beautiful.

[0069] It should be noted that, due to the structural limitations of the automobile itself, the first surface 111 or the second surface 121 of the brake device may be close to the inside or outside of the automobile body. In order to facilitate the installation of the connection structure 14 when it is connected to the counterweight component 2, it is possible to consider setting the connection structure 14 on the side close to the outside of the automobile body, so that the counterweight component 2 can be installed next to the vehicle. When the connection structure 14 is set close to the inside of the automobile body, the counterweight component 2 can be installed by lifting the vehicle body or lowering it under the vehicle.

[0070] A second aspect of the present application provides a brake noise reduction assembly, comprising a brake device and a counterweight component 2. The brake device caliper 1 comprises a first bracket 11 and a second bracket 12 which are spaced apart and arranged opposite to each other, and a receiving space 13 is formed between the first bracket 11 and the second bracket 12, and the receiving space 13 is used to receive a brake disc and a brake pad, and a first surface 111 of the first bracket 11 on a side away from the second bracket 12, and / or a second surface 121 of the second bracket 12 on a side away from the first bracket 11 is provided with a connecting structure 14, and the connecting structure 14 is used to connect the counterweight component 2. The brake device is composed of a brake disc, a brake pad and a caliper 1. During the use of the car, the wear of the brake disc or the brake pad increases, resulting in a decrease in the overall weight of the brake device. The vibration frequency of the brake device with a reduced weight increases during the operation of the car, thereby causing a high-frequency noise problem. The present application provides a noise reduction maintenance method for the brake device through a connection structure 14 on the caliper 1 for connecting a counterweight component 2. When the brake device of the car has a noise problem, the user can use the counterweight component 2 to counterweight the caliper 1 through the connection structure 14 set on the caliper 1, thereby compensating for the weight lost in the brake device due to the wear of the brake disc or the brake pad, so as to ensure that the overall weight of the brake device is maintained at an appropriate level, and ensure that the brake device is at a normal vibration frequency during the operation of the car, thereby avoiding the increase in the vibration frequency after the weight is reduced and the noise generated by the increased tone, thereby playing a role in noise reduction. Through the application of the utility model, the problem that the brake device with a reduced overall weight will generate high-frequency noise during the driving of the car as the wear of the brake disc or the brake pad increases in the prior art is solved, which affects the driving experience of the user.

[0071] In some embodiments, the weight component 2 includes a plurality of detachably connected resonant blocks, and any resonant block among the plurality of resonant blocks is cooperatively connected to the connection structure 14 .

[0072] Specifically, in order to adjust the weight of the counterweight component 2, the present application sets the counterweight component 2 to include a plurality of detachably connected resonance blocks, and the arrangement of the plurality of resonance blocks can be a stacked arrangement, or one of the resonance blocks can be connected to the connection structure 14, and the remaining resonance blocks are arranged in a circumferential array at the center of the resonance block. The weight of the counterweight can be adjusted by the number of connection structures 14 connected to the resonance blocks. When the weight required for counterweighting is large, more resonance blocks are installed in the hole. When the weight required for counterweighting is small, the number of assembled resonance blocks is appropriately reduced.

[0073] Embodiment 3

[0074] A third aspect of the present application provides a new energy vehicle, including a brake noise reduction component.

[0075] The third aspect of the present application provides a new energy vehicle, wherein the brake noise reduction assembly used in the new energy vehicle includes a brake device and a weight component 2, and the weight component 2 is connected with the connection structure 14 of the brake device. The caliper 1 of the brake device has a first bracket 11 and a second bracket 12 that are spaced and arranged opposite to each other, and a receiving space 13 is formed between the first bracket 11 and the second bracket 12, and the receiving space 13 is used to receive a brake disc and a brake pad, and a first surface 111 of the first bracket 11 on a side away from the second bracket 12, and / or a second surface 121 of the second bracket 12 on a side away from the first bracket 11 is provided with a connection structure 14, and the connection structure 14 is used to connect the weight component 2. The brake device is composed of a brake disc, a brake pad and a caliper 1. During the use of the car, the wear of the brake disc or the brake pad increases, resulting in a decrease in the overall weight of the brake device. The vibration frequency of the brake device with a reduced weight increases during the operation of the car, thereby causing a high-frequency noise problem. The present application provides a noise reduction maintenance method for the brake device through a connection structure 14 for connecting a counterweight component 2 on the caliper 1. When the brake device of the car has a noise problem, the user can use the counterweight component 2 to counterweight the caliper 1 through the connection structure 14 set on the caliper 1, thereby compensating for the weight lost in the brake device due to the wear of the brake disc or the brake pad, so as to ensure that the overall weight of the brake device is maintained at an appropriate level, and ensure that the brake device is at a normal vibration frequency during the operation of the car, thereby avoiding the increase in the vibration frequency after the weight is reduced and the noise generated by the increased tone, playing a role in noise reduction, thereby improving the driving environment of the new energy vehicle and improving the user's experience. Through the application of the utility model, the problem that the brake device with a reduced overall weight will generate high-frequency noise during the driving of the car and affect the user's driving experience in the prior art as the wear of the brake disc or the brake pad increases is solved.

[0076] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
