Specific implementation
[0042] The following will be combined with the accompanying Figure 1 to the accompanying Figure 8 The technical scheme in the utility model embodiment is clearly and completely described, obviously, the described embodiment is only a part of the embodiment of the utility model, not all the embodiment. Based on the embodiment in the utility model, all other embodiments obtained by the person skilled in the art without making the creative labor belong to the scope of the utility model protection.
[0043] Embodiment 1
[0044] Figures 1 to 5 As shown in the structure schematic view of a gravity sensing indicating lamp provided by the utility model embodiment, referring to Figure 1 , the gravity sensing indicating lamp includes outer shell body 1 and bottom shell 2, after the bottom shell 2 is assembled on the outer shell body 1, an assembly cavity 3 is formed inside, the assembly cavity 3 has electric control board 4, the electric control board 4 has gravity sensor, microcontroller, light-emitting assembly 42 and battery 5 (not shown in the drawing), the bottom shell 2 can enclose the gravity sensor, microcontroller, light-emitting assembly 42 and battery 5 in the assembly cavity 3, to avoid the dust from outside. The gravity sensor, microcontroller and the light-emitting assembly 42 are all welded on the electric control board 4. The electric control board 4 has a plurality of lines, the gravity sensor, microcontroller and the light-emitting assembly 42 are electrically connected with each other through the lines. The battery 5 is electrically connected with the microcontroller and is controlled by the microcontroller to provide power supply for the gravity sensing indicating lamp.
[0045] The gravity sensor is an electronic device capable of sensing the gravity acceleration of an object, also known as a gravity acceleration sensor. In the gravity sensor, a small mass is usually manufactured using micro-electro-mechanical system (MEMS) technology, which is connected to the base of the sensor through an elastic structure. When the sensor is subjected to gravity, the mass will produce displacement, which will cause changes in physical quantities such as capacitance, resistance, or inductance inside the sensor. By measuring the changes in these physical quantities, the magnitude and direction of the gravity acceleration of the object can be calculated. Therefore, the gravity sensor can be used to detect the running state of the user.
[0046] In this embodiment, the gravity sensor is a three-axis acceleration sensor capable of detecting changes in acceleration of the device in three directions. The three-axis acceleration sensor can simultaneously measure the acceleration in three mutually perpendicular directions (usually defined as X, Y, Z axes). This is achieved by designing three directional sensitive structures inside the sensor, which include detection technologies such as capacitive, piezoelectric, or piezoresistive, each of which can independently measure the acceleration component in that direction. By synthesizing the acceleration data of the three axes, the acceleration vector data of the sensor in space can be obtained.
[0047] In the application of a piezoelectric three-axis acceleration gravity sensor, the X axis is defined as the forward direction of the rider, the Y axis is defined as the lateral movement direction of the rider, and the Z axis is defined as the up-down movement direction of the rider. During the forward movement of the rider, the acceleration on the X axis is close to zero. When the rider turns left, the acceleration on the X axis produces an acceleration component close to the right side of the Y axis. At this time, the sensitive structure in the gravity sensor captures this changing acceleration component and converts it into an electrical signal to send to the microcontroller. In this way, the microcontroller can obtain the real-time state information about the current riding state of the rider sent by the gravity sensor.
[0048] In some other embodiments, the gravity sensor is a capacitive gravity sensor that works based on the principle of capacitance change, which senses the effect of gravity by measuring the distance change between the capacitor plates. When gravity causes displacement of the capacitor plates, the capacitance value changes, and the direction and magnitude of gravity are determined by detecting the change in capacitance value.
[0049] The microcontroller is an electronic component that takes signal or data acquisition, calculation processing, analysis and judgment, and decision-making as input, and sends control instructions to command the work of each electronic device as output. The microcontroller has a program stored therein for changing the light pattern according to the gravity sensor; it is connected to the gravity sensor for receiving and processing the current real-time acceleration information and outputting the light-emitting instructions to the light-emitting component 42.
[0050] The light-emitting component 42 is an electronic element or device capable of converting electrical energy into light energy, widely used in lighting, display, indication and other fields. In the lamp, the light-emitting component 42 is usually composed of several LED lamp beads. The light-emitting component 42 is arranged on the electric control board 4 and connected with the microcontroller, for emitting corresponding light mode according to the light-emitting instruction;
[0051] In use, the gravity sensor is responsible for real-time sensing of the motion state and direction change of the object, converting the detected gravity acceleration information into an electrical signal, and transmitting it to the microcontroller. After receiving data from the gravity sensor, the microcontroller analyzes and processes it. It will determine the user's riding state according to the preset algorithm and logic, such as whether turning, braking, etc. occurs. Then, the microcontroller determines a control signal to the light-emitting component 42, and the light-emitting component 42 executes the light mode matched with the control signal after receiving the control signal, such as receiving left turn, so that the light-emitting component 42 on the left side emits light, and the light-emitting component 42 on the right side does not emit light.
[0052] In some embodiments, as shown in Figure 4 The electric control board 4 includes three sub-electric control boards 41; each of the sub-electric control boards is arranged with at least one group of light-emitting components 42; the three sub-electric control boards 41 are arranged from left to right in the length direction of the shell body 1, and the sub-electric control boards 41 on the left and right sides are symmetrically arranged with the sub-electric control board 41 in the middle.
[0053] Because the overall structure of the gravity sensing indicator lamp is relatively small, the overall structure is a long strip-shaped solid structure, the space of the assembly cavity 3 is limited, the electric control board 4 is divided into three sub-electric control boards 41, and the sub-electric control boards 41 on the left and right sides are arranged symmetrically with the sub-electric control board 41 in the middle in the length direction of the shell body 1, which fully utilizes the space in the length direction of the shell body 1, so that the arrangement of the electric control board 4 in the assembly cavity 3 is more compact.
[0054] In some embodiments, as shown in Figure 5 The shell body 1 includes a basic shell 11 and a light-transmitting shell 12; the light-transmitting shell 12 is assembled on the basic shell 11 and cooperates with the inner wall 112 of the basic shell 11 to form at least one assembly area 14; each of the assembly areas 14 is assembled with one of the sub-electric control boards 41.
[0055] When one of the assembly areas 14 has a problem, since each assembly area 14 has an independent sub-ECU 41, the technician can quickly narrow down the fault range to the sub-ECU 41 of the area, without the need to conduct a comprehensive check on the entire ECU 4, greatly improving the efficiency of fault location. If the entire gravity sensing lamp has only one ECU 4, once the ECU 4 fails, it may cause the entire gravity sensing lamp to fail to work. However, since each assembly area 14 is equipped with an independent ECU 4, even if a sub-ECU 41 fails, it will only affect the display work of the area, and other areas can still operate normally, thereby improving the reliability and stability of the entire gravity sensing lamp.
[0056] In some embodiments, the shell body 1 comprises a basic shell 11 and a light-transmitting shell 12; the basic shell 11 has at least one through hole 111; the light-transmitting shell 12 is assembled on the basic shell 11 and cooperates with the through hole 111 to form at least one light-transmitting area 13.
[0057] It should be understood that the light-transmitting shell 12 can allow the light of the light-emitting assembly 42 to be transmitted to the outside. The light-transmitting area 13 allows the light emitted by the light-emitting assembly 42 to be transmitted in a specific angle and manner, and the light emitted by different light-transmitting areas 13 represents different riding states of the rider. Preferably, the light-transmitting area 13 is arranged in the light-emitting direction of the light-emitting assembly 42. In this way, the light-emitting light of the light-emitting assembly 42 can be transmitted to the outside.
[0058] In some embodiments, the light-transmitting area 13 has at least three, and correspondingly, the light-emitting assembly 42 is provided with at least three groups. The three groups of light-emitting assemblies 42 are arranged from left to right along the length direction of the shell body 1, and respectively represent a left turn light, a middle brake light, and a right turn light. Each light-transmitting area 13 is arranged in the light-emitting direction of each group of light-emitting assemblies 42.
[0059] It should be understood that in this way, when the light-emitting assembly 42 at the left light-transmitting area 13 emits light, it represents that the rider is in a left turn state at this time; when the light-emitting assembly 42 at the middle light-transmitting area 13 emits light, it represents that the rider is in a brake state at this time; and when the light-emitting assembly 42 at the right light-transmitting area 13 emits light, it represents that the rider is in a right turn state at this time.
[0060] It should be noted that the current riding state of the rider represented by the light-emitting component 42 of any one of the light-transmitting areas 13 can be customized, such as when the rider turns left, at which time the light-emitting components 42 on the left side and in the middle emit light at the same time. In actual use scenarios, the number of light-transmitting areas 13 and the number of light-transmitting areas 13 that need to emit light at the same time can be set according to the use scenario, as long as it is convenient for the rider to use.
[0061] Further, the gravity sensing indicator light comprises a bottom shell 2, a connecting piece 6 and a gravity sensing component 4. Figures 6 to 7 As shown, the bottom shell 2 has a clamping groove 21 recessed inward from its surface; the connecting piece 6 has a clamping protrusion 61 on one side, and the other side of the connecting piece 6 is connected with an external device; the clamping protrusion 61 is clamped in the clamping groove 21 to achieve detachable connection of the connecting piece 6 and the bottom shell 2.
[0062] It should be understood that the external device is, for example, a helmet, and the gravity sensing indicator light can be detachably connected with the helmet through the connecting piece 6. In this way, when the gravity sensing indicator light is damaged, a new gravity sensing indicator light can be replaced, avoiding the entire helmet from being unable to display the riding state.
[0063] In use, the connection of the connecting piece 6 and the helmet can be achieved by adhesion, such as setting a double-sided adhesive or other adhesive material on the side of the connecting piece 6 connected with the helmet to fix the connecting piece 6 on the helmet. The side of the connecting piece 6 connected with the gravity sensing indicator light is detachably connected with the gravity sensing indicator light through the cooperation of the clamping protrusion 61 and the clamping groove 21, so that the gravity sensing indicator light can be replaced in time when it is damaged.
[0064] Since the rider will have bumps during riding, in order to prevent the gravity sensing indicator light from falling off the helmet. Further, the bottom of the clamping groove 21 has an upward protruding locking piece 22; the side of the connecting piece 6 connected with the bottom shell 2 has a through hole 62; the through hole 62 extends inward on one side to form an extension piece 621 located in the through hole 62; the extension piece 621 and the through hole 62 cooperate to form an assembly area 622; the assembly area 622 is used to assemble the locking piece 22.
[0065] In use, after the protruding part 61 is engaged into the slot 21, it is further moved along the engagement direction so that the locking member 22 enters the assembly area 622 in the through hole 62. It should be understood that the outer contour of the assembly area 622 matches the outer contour of the locking member 22 so that the assembly area 622 can constrain the locking member 22 within it. This achieves further connection and fixation between the gravity sensor lamp and the connector 6.
[0066] Furthermore, in order to facilitate the removal of the gravity sensor indicator light from the connector 6 during replacement, the outward-facing end face of the extension 621 has an outwardly protruding guide portion 623 with an arc-shaped longitudinal section.
[0067] like Figure 8 As shown, the longitudinal section of the guide portion 623 is arc-shaped, so that when the locking member 22 is unlocked from the assembly area 622, the locking member 22 unlocks along the guide surface of the guide portion 623 in a direction opposite to the snap-fit direction. In this way, the gravity sensor indicator light can be detached from the connector 6 to replace it.
[0068] In summary, this technical solution provides a gravity sensor indicator light that senses the rider's current riding status to emit a corresponding light pattern. It also includes the aforementioned connector 6, which enables a detachable connection between the gravity sensor indicator light and the helmet, allowing for timely replacement of the indicator light in case of damage.
