Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of vehicle manufacturing, in particular to a brake light switch assembly and a vehicle with the brake light switch assembly. Background Art
[0002] The current brake light switch uses a mechanical push rod structure. An iron sheet is welded on the pedal to match the brake light switch. When the pedal is stepped on, the iron sheet on the pedal sinks at the same time. When the iron sheet moves away from the switch to a certain distance, the brake light switch is turned on and the brake light is turned on. When the pedal is released, the pedal returns to its original position, and the iron sheet welded on the pedal also returns to its original position at the same time. When the distance between the iron sheet and the brake light switch is shortened to a certain distance, the brake light switch is disconnected and the brake light is turned off. In the related art, the iron sheet on the brake pedal is welded and fixed to the pedal. When the pedal is stepped on, the iron sheet moves away from the switch, and when the pedal is released, the iron sheet moves closer to the switch. When the pedal cannot return to its original position accurately, there is a gap between the iron sheet and the switch. When the brake light switch reaches the conduction stroke, the brake light will be always on, causing a malfunction. Utility Model Content

[0032] Reference below Figure 1-Figure 5 The brake light switch assembly according to the embodiment of the utility model is described. The brake light switch assembly can adjust the distance between the second sensor 13 and the brake light switch 2, which is beneficial to reduce the gap between the two, avoid the situation where the brake light is always on when the brake pedal 31 cannot be fully returned, improve the accuracy of brake light control, and ensure driving safety.
[0033] like Figure 5 As shown, a brake light switch assembly according to an embodiment of the utility model includes: a brake light switch 2 and an adjustment mechanism 1.
[0034] Among them, when the brake light switch assembly is installed in a vehicle, one of the brake light switch 2 and the adjustment mechanism 1 can be installed on the brake pedal bracket 32 and the other can be installed on the brake pedal 31, such as installing the brake light switch 2 on the brake pedal bracket 32 and installing the adjustment mechanism 1 on the brake pedal 31, or the brake light switch 2 can be installed on the brake pedal 31 and the adjustment mechanism 1 can be installed on the brake pedal bracket 32, so that when the brake pedal 31 moves relative to the brake pedal bracket 32, the adjustment mechanism 1 can move relative to the brake light switch 2.
[0035] It should be noted that the brake pedal bracket 32 is fixed relative to the vehicle body, and the brake pedal 31 is rotatably mounted on the brake pedal bracket 32 so that the brake pedal 31 can rotate relative to the vehicle body, that is, when the user uses the vehicle, the brake pedal 31 can move relative to the vehicle body and the brake pedal bracket 32. Therefore, when the user brakes, the adjustment mechanism 1 can move relative to the brake light switch 2.
[0036] The brake light switch 2 is provided with a first induction member, and the adjustment mechanism 1 includes a control member 11 and a second induction member 13, and the control member 11 is used to control the second induction member 13 to move closer to or farther from the brake light switch 2. In other words, when the user brakes, the second induction member 13 and the control member 11 can move relative to the first induction member along with the movement of the brake pedal 31, and at the same time, when the user does not brake, the distance between the second induction member 13 and the first induction member can also be actively adjusted by the control member 11, so that the distance between the second induction member 13 and the first induction member is flexibly adjustable.
[0037] The brake light switch 2 is configured to control the brake light to turn on when the distance between the brake light switch 2 and the second sensor 13 is greater than a set distance, and to control the brake light to turn off when the distance is less than the set distance. It should be noted that the set distance can be flexibly set according to actual needs, such as the distance between the brake light switch 2 and the second sensor 13 can be set to 2 mm. Therefore, when the user steps on the brake and the distance between the brake light switch 2 and the second sensor 13 is greater than 2 mm, it can be determined that the user has a clear intention to brake, and the brake light switch 2 controls the brake light to turn on. When the distance between the brake light switch 2 and the second sensor 13 is less than 2 mm, it can be determined that the user has not taken a braking operation or has the intention to stop braking. At this time, the brake light is controlled to turn off or remain not turned on, thereby ensuring that the brake light switch 2 can automatically and adaptively control the on state of the brake light during the user's use of the brake. Of course, the set distance is not limited to 2 mm, and can also be 1 mm, 1.2 mm, 1.3 mm or 2.5 mm, 2.8 mm, 2.9 mm, 3 mm, etc. Among them, the first sensing element may include a magnet and a Hall chip, and the second sensing element 13 can be set as an inductive iron sheet. When the distance between the first sensing element and the second sensing element 13 changes, the distance between the magnet and the inductive iron sheet changes, and the Hall chip can calculate the magnetic field change and output different voltage values, thereby realizing the on and off of the brake light switch 2.
[0038] And, the control element 11 is configured to control the second sensing element 13 to be close to the brake light switch 2 when the master cylinder pressure of the brake pedal 31 is a set pressure. That is, the control element 11 can be electrically connected to the body controller so that the control element 11 can obtain the master cylinder pressure of the brake pedal 31 from the body controller.
[0039] It should be noted that the set pressure can be flexibly set according to actual needs, such as the set pressure can be set to 0, or close to 0 and can reflect the pressure value of stopping braking. Therefore, after the user stops braking, the master cylinder pressure of the brake pedal 31 is 0 or close to 0. At this time, if there is a gap between the second sensor 13 and the brake light switch 2, the control component 11 can control the second sensor 13 to approach the brake light switch 2, so that the distance between the second sensor 13 and the brake light switch 2 is less than the set distance, ensuring that the brake light is normally turned off, and after the second sensor 13 is close to the brake light switch 2, it can be ensured that when the brake is stepped on again, the second sensor 13 and the brake light switch 2 gradually increase from 0, ensuring that the brake light is more accurate when it lights up again.
[0040] According to the brake light switch assembly of the embodiment of the utility model, by arranging the brake light switch 2 to actively cooperate with the adjustment mechanism 1, the distance between the second sensor 13 and the brake light switch 2 can be actively adjusted when the brake pedal 31 cannot return to its original position normally, so as to ensure that there is no gap between the second sensor 13 and the brake light switch 2 after braking, thereby ensuring that the brake light is accurately turned off after braking, and ensuring the accuracy of turning the brake light on and off again, and the brake light switch 2 can be disconnected normally, thereby solving the defect of the brake light being always on and preventing the vehicle from being recalled due to the problem of the brake light being always on.
[0041] In some embodiments, the adjustment mechanism 1 also includes a driving member 12, the control member 11 is electrically connected to the driving member 12, the second sensing member 13 is installed at the output end of the driving member 12, and the control member 11 is suitable for controlling the driving member 12 to drive the second sensing member 13 to move closer to or away from the brake light switch 2. In other words, the control member 11 can actively analyze the master cylinder pressure of the brake pedal 31, and when it is necessary to adjust the distance between the second sensing member 13 and the brake light switch 2, a control signal can be output to the driving member 12. After receiving the control signal, the driving member 12 performs a driving operation, thereby controlling the second sensing member 13 to move relative to the first sensing member, thereby realizing the distance adjustment between the second sensing member 13 and the brake light switch 2.
[0042] The driving member 12 can be configured as a driving motor, a driving cylinder or other types of driving members 12, and the configuration method is flexible and optional. Thus, the distance between the second sensing member 13 and the brake light switch 2 can be actively adjusted, the structure is simple, and the adjustment method is easy to implement.
[0043] In some embodiments, Figure 3-Figure 5 As shown, the adjustment mechanism 1 also includes a mounting shell 14, and the control member 11 and the driving member 12 are both mounted in the mounting shell 14, wherein the mounting shell 14 is a relatively closed space, and the control member 11 and the driving member 12 can be relatively fixed in the mounting shell 14, so that the mounting shell 14 can protect the control member 11 and the driving member 12, and at the same time, the control member 11 and the driving member 12 are electrically connected, and the mounting shell 14 can be used to ensure that the electrical connection position is in a dry environment, thereby ensuring the safety of the control of the adjustment mechanism 1.
[0044] like Figure 3 and Figure 4 As shown, the second induction member 13 is located outside the mounting shell 14, and the output end of the driving member 12 penetrates the mounting shell 14 to be connected with the second induction member 13, so that when the driving member 12 performs the adjustment action, the output end of the driving member 12 can drive the second induction member 13 to move relative to the brake light switch 2. In this way, the space environment where the driving member 12 and the control member 11 are located can be relatively stable, and the induction effect of the second induction member 13 can be ensured not to be affected by the mounting shell 14, which is conducive to ensuring reliable control of the brake light.
[0045] In some embodiments, Figure 5 As shown, the mounting shell 14 includes a first shell 141 and a second shell 145, which are detachably connected and used to jointly define an installation space, and the control member 11 and the driving member 12 are located in the installation space. That is, the mounting shell 14 includes a first shell 141 and a second shell 145 which are detachably connected, and the control member 11 and the driving member 12 are installed between the first shell 141 and the second shell 145.
[0046] Therefore, when installing and removing the control member 11 and the driving member 12, the first housing 141 and the second housing 145 can be disassembled to open the installation space, which is convenient for installing and removing the control member 11 and the driving member 12. The structure is simple and the installation is convenient. At the same time, the first housing 141 and the second housing 145 can be formed separately, which is conducive to reducing the difficulty of forming a single structural member and reducing the installation cost.
[0047] In some embodiments, the first shell 141 is provided with a first clamping portion, and the second shell 145 is provided with a second clamping portion. The first clamping portion is clamped and connected with the second clamping portion. Therefore, the first shell 141 and the second shell 145 can be flexibly disassembled relative to each other, with a simple structure and easy installation.
[0048] Among them, the first clamping part and the second clamping part are multiple and matched one by one, so that the first shell 141 and the second shell 145 can be clamped and fixed at multiple positions, improving the connection stability between the first shell 141 and the second shell 145 and preventing the two from automatically separating.
[0049] One of the first clamping portion and the second clamping portion can be configured as a clamping protrusion 147 , and the other can be configured as a clamping hole 142 , so that the clamping protrusion 147 is clamped with the clamping hole 142 to achieve a detachable connection between the first shell 141 and the second shell 145 .
[0050] Specifically, Figure 5 As shown, the inner circumferential wall of the first shell 141 is provided with a plurality of first clamping parts, which can be configured as clamping holes 142, which are spaced apart and distributed on the inner circumferential wall of the first shell 141, and the clamping holes 142 penetrate the first shell 141. Meanwhile, a plurality of second clamping parts are provided at the outer circumferential edge of the second shell 145, which are configured as clamping protrusions 147, and the clamping protrusions 147 are protrudingly provided at the edge of the second shell 145. Therefore, in actual installation, as shown in FIG. Figure 5 As shown, the second shell 145 is buckled toward the first shell 141 so that the multiple snap-in protrusions 147 are snap-into the multiple snap-in holes 142 one by one, thereby achieving snap-in fixation, which is beneficial to improving installation efficiency and facilitating disassembly.
[0051] In some embodiments, the control member 11 is connected to the first housing 141, the control member 11 is provided with a connecting wire harness 111, the second housing 145 is provided with a threading port 146, and the connecting wire harness 111 is passed through the threading port 146. Figure 5 As shown, the first shell 141 is constructed as a box-shaped member with one side open, that is, a box cavity 144 is formed in the first shell 141, and the control member 11 and the driving member 12 can be installed in the box cavity 144.
[0052] At the same time, if Figure 5 As shown, the second shell 145 is constructed as a plate-like member, and the second shell 145 can be snapped onto the open side of the first shell 141 to close the open side, so that the first shell 141 and the second shell 145 jointly define an installation space, and the second shell 145 is provided with a threading port 146 that passes through the second shell 145 along its thickness direction.
[0053] It should be noted that, Figure 5 As shown, the control component 11 can be constructed as a printed circuit board, which includes electrical components such as a CAN chip, and the printed circuit board is connected to a connecting harness 111 and two PIN pins, which can be electrically connected to the driving component 12. The connecting harness 111 on the control component 11 can be passed through the threading port 146 to be electrically connected to an external body controller and power supply.
[0054] In some embodiments, the control component 11 is positioned and matched with the mounting shell 14, and relatively fixed by connecting parts. For example, an axial hole can be set in the mounting shell 14, and a positioning column can be set on the control component 11, so that the control component 11 and the mounting shell 14 can be positioned and installed by plugging and positioning the positioning column and the axial hole. At the same time, connecting parts such as screw joints or rivets can be set to fix the control component 11 and the mounting shell 14, so as to realize the installation method of positioning first and then fixing, which is beneficial to improve the installation efficiency and ensure the installation stability.
[0055] And / or, the driving member 12 is pressed into the mounting shell 14. If a soft rib structure 1411 is set in the mounting shell 14, the driving member 12 can be pressed into the soft rib structure 1411 to achieve the connection and fixation between the driving member 12 and the mounting shell 14, simplify the mounting structure, and reduce the installation cost.
[0056] In some embodiments, the driving member 12 is constructed as a telescopic motor, and the telescopic motor may be provided with a motor harness 121, and the motor harness 121 is welded and fixed to two PIN needles of the control member 11 to form a loop, which is conducive to the control of the telescopic motor.
[0057] The motor shaft of the driving member 12 is configured as a telescopic shaft 122, that is, the telescopic shaft 122 is the output end of the driving member 12, and the second induction member 13 is installed at the free end of the telescopic shaft 122. Figure 3 and Figure 4 As shown, the motor shaft of the driving member 12 passes through the top of the mounting shell 14 to extend outside the mounting shell 14, and a second sensing member 13 is arranged above the driving member 12. Therefore, when the telescopic motor is running, the telescopic shaft 122 extends relative to the mounting shell 14 to drive the second sensing member 13 to approach the brake light switch 2, thereby facilitating reducing the gap between the second sensing member 13 and the brake light switch 2.
[0058] In some embodiments, the adjustment mechanism 1 further includes a connecting bracket 15 , which is suitable for being detachably connected to the brake pedal 31 , and the connecting bracket 15 is formed with a connecting groove 151 , and the mounting shell 14 is detachably mounted at the connecting groove 151 .
[0059] like Figure 5 As shown, a connection groove 151 is formed on one side of the connection bracket 15 facing the first shell 141, and the shape of the connection groove 151 is adapted to the shape of the mounting shell 14, so that the mounting shell 14 and the internal structural parts are all installed in the connection groove 151. Among them, the connection bracket 15 is a semi-open structure. After the mounting shell 14 is installed in the connection groove 151, the second sensor 13 is located outside the connection groove 151 and can extend relative to the connection bracket 15 to flexibly adjust the distance between the second sensor 13 and the first sensor.
[0060] Among them, by providing the connecting bracket 15, the adjustment mechanism 1 can be effectively installed on the brake pedal 31, and during the actual installation, the connecting bracket 15 can be connected and fixed to the brake pedal 31 through the connecting bolts 16, such as Figure 3-Figure 5 As shown, the connection bracket 15 is provided with three connection bolts 16, which can be connected and fixed with the brake pedal 31 at different positions, which is conducive to ensuring the connection stability. Figure 5 As shown, a snap-in boss 143 is provided on the outer peripheral wall of the first shell 141. At the same time, the connecting bracket 15 is provided with a snap-in interface 152. There are two snap-in bosses 143 and they can be snap-into the two snap-in interfaces 152 one by one, so as to realize the snap-in fixation of the mounting shell 14 and the connecting bracket 15. The connection is simple and the disassembly is convenient.
[0061] Furthermore, the brake light switch 2 further includes a switch bracket 21 , and the brake light switch 2 can also be installed on the brake pedal bracket 32 through the switch bracket 21 , so that the brake light switch 2 and the brake pedal bracket 32 are relatively fixed.
[0062] The utility model also provides a vehicle.
[0063] According to the vehicle of the embodiment of the utility model, a brake light switch assembly of any one of the above-mentioned embodiments is provided, and by arranging the brake light switch 2 to actively cooperate with the adjustment mechanism 1, the distance between the second sensor 13 and the brake light switch 2 can be actively adjusted when the brake pedal 31 cannot return to its position normally, so as to ensure that there is no gap between the second sensor 13 and the brake light switch 2 after braking, thereby ensuring that the brake light is accurately turned off after braking, and ensuring the accuracy of the brake light being turned on and off again, and the brake light switch 2 can be disconnected normally, thereby solving the defect of the brake light being always on, and preventing the vehicle from being recalled due to the problem of the brake light being always on.
[0064] Among them, when the brake light switch assembly is actually used in a vehicle, the following adjustment operations can be performed:
[0065] 1. When the user steps on the brake pedal 31: the brake pedal 31 sinks. Since the adjustment mechanism 1 is screwed to the brake pedal 31 through the connecting bracket 15, the brake pedal 31 will drive the adjustment mechanism 1 to sink as a whole, and the inductive iron sheet on the adjustment mechanism 1 will move away from the brake light switch 2. When the gap between the inductive iron sheet and the brake light switch 2 is greater than 2 mm, the brake light switch 2 is turned on, and the body controller detects the switch-on signal and turns on the brake light.
[0066] 2. Release the pedal: the brake pedal 31 is lifted, and the brake pedal 31 drives the adjustment mechanism 1 to lift as a whole, and the inductive iron sheet on the adjustment mechanism 1 will be close to the brake light switch 2. When the gap between the inductive iron sheet and the brake light switch 2 is less than 2mm, the brake light switch 2 is disconnected, and the body controller detects the switch disconnection signal and turns off the brake light. In the present invention, the adjustment mechanism 1 is set, and the adjustment mechanism 1 receives the master cylinder pressure signal of the brake pedal 31. When the brake pedal 31 automatically returns to its position and the master cylinder pressure signal is 0 bar, the telescopic motor of the adjustment mechanism 1 drives the inductive iron sheet to extend. When the inductive iron sheet touches the brake light switch 2, the motor is subjected to resistance, and the motor working current will rise sharply. The chip of the adjustment mechanism 1 detects the increase in current. When the current exceeds a certain threshold (such as 1A, this value can be calibrated by experiment), the chip controls the motor to stop immediately. At this time, it can ensure that the gap between the inductive iron sheet and the brake light switch 2 is 0, and the brake light remains off.
