Description

Tire monitoring device

[0001] The present invention relates to a tire monitoring device, and more particularly, to a tire monitoring device having a casing structure that improves the bonding strength and durability of a tire monitoring device that monitors and stores tire information such as pressure, temperature, and rotation speed of an automobile tire.

[0002] Checking tire pressure, temperature, rotation speed, etc. is a very important part of vehicle maintenance and safe driving. In particular, tire pressure must be maintained at the preset pressure to ensure that the tires drive safely as intended by the manufacturer.

[0003] For this reason, a Tire Monitoring System (TMS) has been developed and is being used to manage tire and driving conditions by wirelessly transmitting and receiving information related to the driving environment, including tire pressure, driving history, driving habits, and road conditions, to and from an external management device.

[0004] In the tire monitoring system as described above, the TMS module (10) is directly mounted on the tire (1) as shown in the attached drawing 1 to monitor the condition of the tire, and therefore resistance or durability to harsh environmental stresses such as high pressure and high heat applied during driving is required.

[0005] To this end, as shown in the attached drawing 2, when accommodating the functional part (13) and the battery part (14) in the bottom case (11) and the top case (12), an epoxy mold (15) (EMC, epoxy molding compound) was filled to secure fixation and durability.

[0006] However, the above conventional technology has a problem in that a micro-gap is formed between the top case (12) and the epoxy mold (15) due to a tolerance when the epoxy mold (15) is hardened, and the gap between the top case (12) and the epoxy mold (15) is further expanded by harsh environmental stress such as high pressure and high temperature including external pressure, thereby reducing the airtightness.

[0007] In addition, the conventional technology as described above has a problem in that shock or stress is transmitted to the built-in elements as the cases are pressed due to the above-mentioned clearance, which shortens the lifespan and reduces the durability of the tire monitoring module as a whole.

[0008] The present invention relates to a casing structure of a tire monitoring device, and aims to provide a tire monitoring device with an improved casing structure to improve the bonding strength and durability of the tire monitoring device, which monitors and stores tire information such as pressure, temperature, and rotation speed of an automobile tire.

[0009] The present invention may include a functional unit having an electric circuit having a sensing and wireless transmission / reception function, including a pressure sensor, mounted on a PCB; a power unit provided at a lower portion of the functional unit to supply power to the functional unit; a power terminal connecting the power unit and the circuit of the functional unit; a top case and a bottom case that are vertically coupled to accommodate the components; a top molding unit provided between the upper portion of the functional unit and the top case; a bottom molding unit provided between the power unit at the lower portion of the functional unit and the bottom case; and a reinforcing molding unit that is applied to an upper portion of the top molding unit and is diffusion-cured to an area excluding the pressure sensor by a bonding pressure of the top case.

[0010] In the present invention, the functional unit may include a PCB installed above the bottom case; and a functional circuit including a pressure sensor mounted on the upper portion of the PCB and a plurality of chips that monitor and provide stored tire information such as temperature and rotation speed.

[0011] In the present invention, the power supply unit may include a battery; and a power circuit that converts the power of the battery into rated power and supplies it as operating power of the functional unit.

[0012] In the present invention, the power terminal may be connected to the + and - terminals of the power supply unit, respectively, and may be connected to the terminal of the functional unit.

[0013] The power terminal of the present invention may be connected by protruding from the upper portion of the functional part.

[0014] In the present invention, the top molding part may be an epoxy mold formed to wrap the upper part of the functional part excluding the pressure sensor before being accommodated in the case assembly.

[0015] [Revised on 03.01.2024 by Rule 91] The top molding part of the present invention may be a volume body in which groove members are formed at intervals so that the part where the pressure sensor is located is exposed.

[0016] [Correction under Rule 91 03.01.2024] A flat cross-section may be formed by forming a '┏┓' shaped groove in a part of a circular volume.

[0017] In the present invention, the bottom molding part may be an epoxy mold formed to wrap the power supply part on the lower part of the functional part before being accommodated in the case assembly.

[0018] In the present invention, the reinforcing molding part may be a silicone mold that is applied to multiple areas on the upper part of the top molding part and is cured in a compressed and spread state by the pressure generated when the top case is joined to the bottom case.

[0019] The reinforcing molding part of the present invention may be diffused or guided to a region excluding the pressure sensor by a diffusion-preventing part provided on the upper surface of the top molding part, and then filled in the gap between the top molding part and the top case and then cured.

[0020] In the present invention, the portion excluding the pressure sensor may be the upper portion including the sensor hole of the pressure sensor.

[0021] The reinforcing molding part of the present invention may be formed by inducing diffusion to a region other than the pressure sensor direction by a diffusion inducing part provided on the upper surface of the top molding part, and then filling the gap between the top molding part and the top case and then curing.

[0022] The reinforcing molding part of the present invention may be spread into the gap between the top molding part and the top case, passed through the outer edge of the functional part, and then guided into the gap between the power part and the bottom case and the bottom molding part, and then cured.

[0023] The top molding part of the present invention may be a volume body in which a groove member is formed so that a portion where a pressure sensor is located is exposed, and a diffusion blocking part in the shape of '∩' or '┏┓' may be protruded along the upper edge of the groove member to contact the lower surface of the top case.

[0024] The top molding part of the present invention may be inclined downward in the direction of the upper outer edge excluding the direction in which the pressure sensor is located.

[0025] The top molding part of the present invention may have an upper outer edge portion curved except for the direction in which the pressure sensor is located.

[0026] The top molding part of the present invention may be provided with a diffusion induction part composed of a plurality of radial slits in a direction excluding the direction in which the pressure sensor is located from the area where the reinforcing molding part is applied.

[0027] The top molding part of the present invention may have grooves formed in each part where the reinforcing molding part is applied.

[0028] A plurality of slits may be provided radially from the groove of the present invention in a direction other than the direction in which the pressure sensor is located.

[0029] The present invention provides a tire monitoring device that monitors and stores tire information such as pressure, temperature, and rotation speed of an automobile tire by applying a reinforcing molding part, which is an epoxy mold, to a plurality of areas on the upper surface of the top molding part, and by curing the reinforcing molding part while filling the gap between the top case and the functional part while compressing and spreading during the process of covering the top case and casing, thereby obtaining the effect of improving the fixing bonding strength of the entire case and internal components.

[0030] The present invention obtains the effect of improving the durability of a tire monitoring device applied in a tire that is exposed to high-speed rotation, strong vibration, and harsh temperature conditions for a long period of time by ensuring the overall sturdiness of the tire monitoring device by hardening the reinforcing molding part while mostly filling the gap between the top case, the functional part, and the top molding part through compression and diffusion as described above.

[0031] The present invention prevents the pressure sensor from being directly covered by the reinforcing molding part by diffusion or induction to a region other than the pressure sensor through a diffusion-preventing part provided on the upper edge of the groove member of the top molding part, thereby preventing the pressure sensor from being degraded or rendered inoperable by preventing the upper surface where the pressure sensor hole is located from being directly covered by the reinforcing molding part.

[0032] The present invention has the effect of preventing the pressure sensor from being degraded or rendered inoperable by preventing the pressure sensor from being directly covered by the reinforcing molding part, since the upper surface of the top molding part, excluding the direction in which the pressure sensor is located, is inclined downward toward the outer edge, so that the amount of diffusion in the other direction is greater than the direction in which the pressure sensor is located during the process of the reinforcing molding part being compressed by the pressure of the top case.

[0033] The present invention is characterized in that the reinforcing molding part is filled in the gap between the top molding part, the top case, and the top molding part and then hardened in a state where diffusion is concentrated in a region excluding the direction of the pressure sensor along a radial slit, which is a diffusion inducing part provided on the upper surface of the top molding part, thereby preventing the upper surface where the sensor hole of the pressure sensor is located from being directly covered by the reinforcing molding part, thereby obtaining the effect of preventing the occurrence of a state in which the pressure sensor is in a state of reduced operation or inoperability.

[0049]

[0050] Hereinafter, the present invention will be described with reference to the attached drawings.

[0051] First, the tire monitoring device (100) of the present invention, as illustrated in the attached drawings Figs. 3 to 6, includes: a functional unit (110) in which an electric circuit (112) having a sensing and wireless transmission / reception function, including a pressure sensor (111), is mounted on a PCB (113); a power supply unit (120) provided at the bottom of the functional unit (110) to supply power to the functional unit (110); a power terminal (130) connecting the power supply unit (120) and the circuit of the functional unit (110); a top case (140) and a bottom case (150) that are vertically coupled to accommodate the components; a top molding unit (160) provided between the upper portion of the functional unit (110) and the top case (140); a bottom molding unit (170) provided between the power supply unit (120) at the bottom of the functional unit (110) and the bottom case (150); And it may include a reinforcing molding part (180) that is applied on the upper part of the top molding part (160) and is diffusion-hardened to an area excluding the pressure sensor (111) by the bonding pressure of the top case (140).

[0052] The tire monitoring device (100) of the present invention may be installed on each tire mounted on a vehicle, i.e., a left front tire, a right front tire, a left rear tire, and a right rear tire, and may collect or measure and store information related to the condition of the corresponding tire (e.g., tire condition information).

[0053] The method of measuring this tire condition information may vary depending on the condition information measurement mode, which is the measurement mode.

[0054] For example, the type of status information measurement mode may include a continuous mode that continuously measures the status information when the vehicle is in a driving state and a power saving mode that measures the status information at set intervals, and the type of status information measurement mode may be determined according to a signal transmitted from a user terminal (not shown).

[0055] The present invention provides a tire monitoring device (100) that monitors and stores tire information such as pressure, temperature, and rotation speed of an automobile tire by applying a reinforcing molding part (180) which is an epoxy mold to multiple parts on the upper surface of the top molding part (160), and as shown in the attached drawing, FIG. 6, in the process of covering the top case (140) and forming a casing, the reinforcing molding part (180) is compressed and spread, thereby filling the gap between the top case (140) and the functional part (110) and curing, thereby increasing the bonding strength of the entire case (140) (150) and the internal components (110) (120) (130) (160) (170).

[0056] In addition, the present invention hardens while the reinforcing molding part (180) is compressed and spread as described above, thereby filling most of the gap between the top case (140), the functional part (110), and the top molding part (160), thereby securing the overall sturdiness of the tire monitoring device (100), thereby increasing the durability of the tire monitoring device (100) applied in a tire that is exposed to high-speed rotation, strong vibration, and harsh temperature conditions for a long time.

[0057] Here, the functional part (110) of the present invention may include a PCB (113) placed above a bottom case (150); and a pressure sensor (111) mounted on the upper portion of the PCB (113) and a functional circuit (112) including a plurality of chips that monitor and provide stored tire information such as temperature and rotation speed.

[0058] The type of tire condition information collected by the functional unit (110) of the present invention may be at least one of tire pressure, tire temperature, tire rotation speed, driving time and driving distance, and tire humidity.

[0059] In order to obtain such tire condition information, the functional unit (110) may be equipped with various types of sensors, and may be equipped with a control unit and memory that can calculate driving time and driving distance, etc. using signals detected by the sensors.

[0060] At this time, the sensor mounted on the functional unit (110) of the present invention may be a pressure sensor that detects the air pressure inside the tire, a temperature sensor that detects the temperature inside the tire, an acceleration sensor that detects acceleration to calculate the driving time and driving distance of the vehicle, and a humidity sensor that detects the humidity inside the tire.

[0061] At this time, the functional unit (110) of the present invention may further include a low-frequency communication module or a short-range communication module to enable two-way communication between each component or with an external control device.

[0062] Meanwhile, the power supply unit (120) of the present invention may include a battery; and a power circuit that converts the power of the battery into rated power and supplies it as operating power of the functional unit.

[0063] The power supply unit (120) of the present invention may be equipped with a TMS self-location solution.

[0064] At this time, the battery of the present invention may be a coin-type dedicated battery that can be operated for 5-7 years or more.

[0065] At this time, the battery of the present invention may also be mounted so that the negative electrode is positioned toward the outside (toward the tire attachment surface) to prevent electrolyte separation.

[0066] At this time, the power circuit of the present invention may also be applied with a wireless charging solution.

[0067] Meanwhile, the power terminal (130) of the present invention may be connected to the + and - terminals of the power unit (120), respectively, and may be connected to the terminal of the functional unit (110).

[0068] At this time, the power terminal (130) of the present invention is connected to the upper portion of the functional portion (110) in an exemplary manner, but may be connected to the lower portion without protruding from the upper portion of the functional portion (110).

[0069] Meanwhile, the top case (140) of the present invention may have an air hole formed through the upper portion.

[0070] The air hole of the present invention may be a path through which gas generated during the process of hardening the reinforcing molding part (180) is exhausted.

[0071] At this time, the top case (140) and bottom case (150) of the present invention primarily block or provide resistance to stress conditions including external pressure acting within the tire (1), while providing an external surface that enables the tire (1) to be fixed within the tire.

[0072] Meanwhile, the top molding part (160) of the present invention may be an epoxy mold formed to wrap the upper part of the functional part (110) excluding the pressure sensor (111) before accommodating the components in the case assembly, i.e., the top case (140) and the bottom case (150).

[0073] The top molding part (160) of the present invention may be a volume body in which groove members (161) are formed at intervals so that the part where the pressure sensor (111) is located is exposed.

[0074] [Revised 03.01.2024 according to Rule 91] At this time, the top molding part (160) may be formed by forming a groove in the shape of '┏┓' on a part of a circular volume with a flat cross section.

[0075] The home member (161) of the top molding part (160) as described above provides a space in which the pressure sensor (111) can be exposed to the outside, thereby preventing the pressure sensor (111) that detects external pressure through the sensor hole from being wrapped by the top molding part (160) and becoming airtight, thereby ensuring that the pressure sensor (111) operates accurately.

[0076] For reference, the reason why the reinforcing molding part (180) in the present invention prevents or minimizes the pressure sensor from being guided in the direction of the pressure sensor during compression diffusion is to prevent the pressure sensor (111) from being directly wrapped by the reinforcing molding part (180) and becoming airtight, thereby ensuring that the pressure sensor (111) operates accurately.

[0077] The top molding part (160) of the present invention as described above blocks stress conditions including external pressure from being applied to the functional part (110) accommodated in the top case (140).

[0078] Meanwhile, the bottom molding part (170) of the present invention may be an epoxy mold formed to wrap the power supply part (120) around the lower part of the functional part (110) before accommodating the components in the case assembly, i.e., the top case (140) and the bottom case (150).

[0079] The bottom molding part (170) of the present invention as described above blocks stress conditions including external pressure from being applied to the power supply part (120) accommodated in the bottom case (140).

[0080] Meanwhile, the reinforcing molding part (180) of the present invention may be a silicone mold that is applied to multiple areas on the upper part of the top molding part (160) and is cured in a compressed and spread state by the pressure generated when the top case (140) is joined to the bottom case (150).

[0081] The reinforcing molding part (180) of the present invention may be applied in 2 to 6 parts at intervals on the upper part of the top molding part (160).

[0082] At this time, the amount of the reinforcing molding part (180) of the present invention applied is sufficient if it is a volume that can fill about 80 to 90% of the empty space (excluding a portion of the pressure sensor) excluding the functional part (110) and the top molding part (160) within the top case (140) in a compressed and spread state.

[0083] The reinforcing molding part (180) of the present invention as described above is applied to the upper surface of the top molding part (160), and then is compressed and spread outward from the upper surface of the top molding part (160) by the downward pressure of the top case (140), thereby filling the gap between the top case (140), the functional part (110), and the top molding part (160) and curing, thereby increasing the bonding strength and durability of the entire case (140) (150) and the internal components (110) (120) (130) (160) (170).

[0084] And, as shown in the attached drawing 7, the top molding part (160) of the present invention may be a volume body in which a groove member (161) is formed so that a portion where a pressure sensor (111) is located is exposed, and a diffusion blocking part (162) in the shape of '∩' or '┏┓' may be protruded along the upper edge of the groove member (161) to contact the lower surface of the top case (140).

[0085] In this way, the reinforcing molding part (180) is diffused or guided to a region other than the pressure sensor (111) by the diffusion preventing part (162) provided on the upper edge of the groove member (161) of the top molding part (160), thereby preventing the upper surface where the sensor hole of the pressure sensor (111) is located from being directly covered by the reinforcing molding part (180), thereby preventing the pressure sensor (111) from being degraded or rendered inoperable.

[0086] The reinforcing molding part (180) as described above is filled in the gap between the top molding part (160) and the top case (140) and then hardened while being diffused or guided to a region excluding the pressure sensor (111) by the diffusion blocking part (162) provided on the upper edge of the groove member (161) of the top molding part (160). Of course, at this time, the reinforcing molding part (180) diffused or guided to a region excluding the pressure sensor (111) may pass through another region and then diffuse to the pressure sensor (111) region according to the volume, thereby filling up to a portion of the lower portion of the pressure sensor (111).

[0087] At this time, in the present invention, the part excluding the pressure sensor (111) may be the upper part including the sensor hole of the pressure sensor (111).

[0088] And, as shown in a) and b) of the attached drawing Fig. 8, the top molding part (160) of the present invention may have an upper surface slanted downward toward the outer edge, excluding the direction in which the pressure sensor (111) is located.

[0089] As described above, the present invention has a top molding part (160) that slopes downward in the direction of the outer edge except for the direction in which the pressure sensor (111) is located, so that when the reinforcing molding part (180) is compressed by the pressure of the top case (140), the amount of diffusion in the other direction is greater than the direction in which the pressure sensor (111) is located, thereby preventing the upper surface where the sensor hole of the pressure sensor (111) is located from being directly covered by the reinforcing molding part (180), thereby preventing the pressure sensor (111) from being degraded or rendered inoperable.

[0090] In addition, the top molding part (160) of the present invention may have an upper outer edge portion curved except for the direction in which the pressure sensor (111) is located, as shown in the attached drawing, FIG. 9.

[0091] As described above, the present invention has a top molding part (160) with an upper outer edge portion curved and inclined except for the direction in which the pressure sensor (111) is located, so that when the reinforcing molding part (180) is pressed by the pressure of the top case (140), the pressure sensor (111) is rapidly induced to spread along the curved portion compared to the direction in which the pressure sensor (111) is located, thereby minimizing direct covering of the upper surface where the sensor hole of the pressure sensor (111) is located by the reinforcing molding part (180), thereby preventing the pressure sensor (111) from being degraded or rendered inoperable.

[0092] And, as shown in the attached drawing Figure 10, the top molding part (160) of the present invention may be provided with a diffusion inducing part (163) composed of a number of radial slits in a direction excluding the direction in which the pressure sensor (111) is located from the area where the reinforcing molding part (180) is applied.

[0093] The present invention, as described above, is such that the reinforcing molding part (180) is diffusion-induced in a concentrated manner in a region excluding the direction of the pressure sensor (111) along the radial slit, which is the diffusion-inducing part (163) provided on the upper surface of the top molding part (160) by the pressure of the top case (140), and is then filled in the gap between the top molding part (160), the top case (140), and the top molding part (160), and then hardened, thereby preventing the upper surface where the sensor hole of the pressure sensor (111) is located from being directly covered by the reinforcing molding part (180), thereby preventing the pressure sensor (111) from being degraded or rendered inoperable.

[0094] At this time, the reinforcing molding part (180) may be spread into the gap between the top molding part (160) and the top case (140), and may be guided through the outer edge of the functional part (110) to the gap between the power part (120), the bottom case (150), and the bottom molding part (170), and then hardened, thereby making it possible to fill the entire gap or free space inside the case.

[0095] At this time, the top molding part (160) of the present invention may have a groove (not shown) formed in each portion where the reinforcing molding part (180) is applied, and at this time, a diffusion inducing part (163) which is a plurality of radial slits may be further provided from the groove in a direction other than the direction in which the pressure sensor (111) is located.

[0096] Since this has the same effect as that of the attached drawing 10, a detailed description is omitted.

[0097] The technical features disclosed in each embodiment of the present invention are not limited to that embodiment, and, unless they are mutually incompatible, the technical features disclosed in each embodiment may be combined and applied to different embodiments.

[0098] Therefore, although each embodiment focuses on its own technical features, each technical feature can be applied in combination with each other as long as they are not mutually incompatible.

[0099] The present invention is not limited to the above-described embodiments and the attached drawings, and various modifications and variations are possible within the scope of those skilled in the art. Therefore, the scope of the present invention should be defined not only by the claims of this specification but also by equivalents thereof.
