Japanese Patent No. 4541310

  Now, a liquid level detection module in which a liquid level detector is fixed to a container by a fixing member such as a bracket instead of the cup as in Patent Document 1 is generally known. Such a liquid level detection module does not have a configuration corresponding to a cup that protects the liquid level detector. Therefore, when the fixing member holding the liquid level detector is inserted into the container through the opening formed in the container, the liquid level detector can come into contact with the periphery of the opening of the container. Therefore, the liquid level detector may be damaged when the liquid level detection module is assembled to the container.

  The present invention has been made in view of the above problems, and an object of the present invention is to provide a liquid level detection module capable of avoiding damage to the liquid level detector when assembled to a container with a simple configuration.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings. A liquid level detection module 100 according to an embodiment of the present invention is installed in a vehicle and is installed in a fuel tank 90 that stores fuel as liquid as shown in FIG. First, the configuration of the liquid level detection module 100 will be described.

  The liquid level detection module 100 includes a fuel sender 10, a lid 20 attached to the fuel tank 90, a bracket plate 30 that holds the fuel sender 10, and the like. In the following description, the axial direction of the opening 95 provided in the ceiling portion 93 of the tank 90 in order to insert the liquid level detection module 100 into the fuel tank 90 is the insertion direction ID of the liquid level detection module 100. To do. Further, a direction substantially orthogonal to the insertion direction ID and along the planar direction of the bracket plate 30 is defined as a width direction WD, and further, a direction substantially orthogonal to the insertion direction ID and along the thickness direction of the bracket plate 30 Is a standing direction SD. The fuel sender 10 shown in FIGS. 1 and 2 detects the height of the liquid level of the fuel stored in the fuel tank 90. The fuel sender 10 includes a float 55, a magnet holder 50, a housing 40, a Hall IC 60, and the like.

  The float 55 is formed of a material having a specific gravity smaller than that of a fuel such as foamed ebonite. The float 55 can float on the fuel level. The float 55 is supported on the magnet holder 50 by a float arm 56 made of a metal material such as stainless steel.

  The magnet holder 50 is formed in a cylindrical shape using, for example, polyacetal (POM) resin. The magnet holder 50 holds the float arm 56. The magnet holder 50 is rotatably supported by the housing 40. A pair of magnets 53 exhibiting ferromagnetism are embedded in the magnet holder 50. These magnets 53 rotate integrally with the magnet holder 50.

  The housing 40 is made of, for example, polyphenylene sulfide (PPS) resin. The housing 40 is a member attached to the bracket plate 30 and includes a bottom wall portion 41, a peripheral wall portion 43, and a support shaft 45. The bottom wall portion 41 is formed in a plate shape and is supported by the bracket plate 30 in the standing direction SD. The peripheral wall portion 43 is erected from the peripheral portion 42 of the bottom wall portion 41 toward the magnet holder 50 along the erection direction SD. The peripheral wall 43 is formed so as to surround the bottom wall 41. The support shaft 45 protrudes in a cylindrical shape from the bottom wall portion 41 along the standing direction SD. The support shaft 45 accommodates the Hall IC 60. The housing 40 supports the magnet holder 50 rotatably by fitting the bearing portion of the magnet holder onto the support shaft 45.

  The Hall IC 60 is a detection element that detects the rotation angle of the magnet holder 50 with respect to the support shaft 45. The Hall IC 60 is embedded in the support shaft 45 of the housing 40 so as to be sandwiched between a pair of magnets 53 provided in the magnet holder 50. The Hall IC 60 is connected to equipment outside the fuel tank 90 via three lead wires 61 to 63 and a terminal. The Hall IC 60 receives an action of a magnetic field from the outside in a state where a voltage is applied, and outputs a voltage proportional to the density of the magnetic flux passing through the Hall IC 60 to an external device as an output result.

  With the above configuration, the reciprocating motion of the float 55 that moves up and down following the fuel by the float arm 56 supported by the magnet holder 50 is converted into a rotational motion to be an integral element composed of the float arm 56 and the magnet holder 50. Communicated. Therefore, the magnet holder 50 follows the liquid level of the fuel stored in the fuel tank 90 and rotates relative to the housing 40. Due to the relative rotation of the magnet holder 50, the magnetic flux density of the magnetic field acting on the Hall IC 60 changes, whereby the voltage output from the Hall IC 60 changes. In this way, the fuel sender 10 realizes detection of the rotation angle of the magnet holder 50 and consequently the height of the fuel level.

  The lid 20 shown in FIG. 1 is formed of a resin material or the like in a disk shape having a larger diameter than the opening 95 and closes the opening 95. A lid 21 and a connector part 23 are formed on the lid 20. The flange 21 protrudes annularly outward in the radial direction from the main body portion of the lid body 20, and is in liquid-tight contact with the peripheral portion 96 of the opening 95 from the outside of the fuel tank 90. The connector portion 23 protrudes from the main body portion of the lid body 20 toward the outside of the fuel tank 90. In order to electrically connect the Hall IC 60 and an external device, a mating connector portion (not shown) connected to the external device is fitted into the connector portion 23.

  The bracket plate 30 shown in FIGS. 1, 3 and 4 is formed of a metal material or the like in a plate shape having a longitudinal direction, and is held by the lid body 20. The bracket plate 30 includes a guard wall portion 37 to be described later in addition to the bracket main body portion 31, the clamping claw portion 32, the guide wall portion 33, and the restriction portion 35.

  The bracket main body 31 extends in a strip shape from the lid 20 along the insertion direction ID that is the axial direction of the lid 20. The extending direction in which the bracket body 31 extends is the longitudinal direction of the bracket plate 30. The bracket main body 31 is located on the opposite side of the magnet holder 50 with the housing 40 interposed therebetween, and can support the contacting bottom wall 41 in the standing direction SD.

  The sandwiching claw portion 32 is located between the guide wall portion 33 and the guard wall portion 37 in the insertion direction ID. One clamping claw portion 32 faces the other one clamping claw portion 32 in the width direction WD. Two such pair of clamping claws 32 are arranged in the insertion direction ID. These four clamping claws 32 extend from the outer edge portion of the bracket body 31 in the width direction WD toward the outside in the width direction WD. Each distal end portion in the extending direction of each clamping claw portion 32 is folded back toward the inner side in the width direction WD, and is positioned to face the main body portion 31 in the standing direction SD.

  The guide wall portion 33 is located in a direction opposite to the insertion direction ID of the clamping claw portion 32. The guide wall portion 33 is erected along the standing direction SD from the outer edge portion in the width direction WD of the bracket main body portion 31 toward the housing 40 side. A pair of guide wall portions 33 are provided facing the width direction WD. The pair of guide wall portions 33 each extend along the insertion direction ID. In addition, the distance between the pair of guide wall portions 33 corresponds to the dimension of the housing 40 in the width direction WD.

  The restriction portion 35 is formed by a restriction opening 35 a provided between the pair of guide wall portions 33. The restriction opening 35a has a shape in which two band-shaped openings extending along the width direction WD are made continuous at the end portions with band-shaped openings extending along the insertion direction ID. Due to the shape of the restriction opening 35 a, the restriction part 35 has a rectangular shape in which one side is continuous with the bracket body part 31. In addition, one of the two sides of the restricting portion 35 along the width direction WD, which is located in the insertion direction ID, is in a direction opposite to the insertion direction ID as the distance from the continuous portion of the restricting portion 35 and the bracket body portion 31 increases. An inclined portion 36 that is inclined is formed.

  The process of attaching the fuel sender 10 to the bracket plate 30 will be described with reference to FIGS.

  First, the bottom wall portion 41 is brought into contact with a portion of the bracket body portion 31 that is located closer to the guide wall portion 33 than the pinching claw portion 32. At this time, the housing 40 is sandwiched by the pair of guide wall portions 33 from the outside in the width direction WD. Then, the peripheral wall 43 is slid with respect to the guide wall 33 and the bottom wall 41 is slid with respect to the bracket body 31, whereby the housing 40 is relatively displaced with respect to the bracket plate 30 in the insertion direction ID. Thereby, the housing 40 pushed between the clamping claw part 32 and the bracket main body part 31 is clamped by the clamping claw part 32 and the bracket main body part 31 that cooperate with each other by the restoring force of the clamping claw part 32.

  Further, the restricting portion 35 is positioned closer to the housing 40 than the bracket main body portion 31 by plastically deforming the continuous portion of the restricting portion 35 and the bracket main body portion 31 (see the arrow in FIG. 6). At this time, the inclined portion 36 that comes into contact with the peripheral wall portion 43 exerts an action of pushing down the housing 40 in the insertion direction ID. As a result, the housing 40 moves to a predetermined position on the bracket plate 30. In addition, in a posture inclined with respect to the bracket main body 31, the restricting portion 35 positioned in the standing direction SD with respect to the main body 31 comes in contact with the housing 40, and thus the direction opposite to the insertion direction ID. The relative displacement of the housing 40 toward is regulated. As described above, the fuel sender 10 is held by the bracket plate 30.

  The guard wall portion 37 and the like that are characteristic configurations of the bracket plate 30 will be described in detail. As shown in FIGS. 1 and 3, the guard wall portion 37 is erected from the distal end portion in the insertion direction ID of the bracket main body portion 31 toward the housing 40 side in the erection direction SD. The guard wall portion 37 has a flat plate shape and is formed by bending the base material of the bracket plate 30 in the standing direction SD at the tip portion in the insertion direction ID. In the present embodiment, the pair of guard wall portions 37 formed by bending the base material of the bracket plate 30 is located in the insertion direction ID of the housing sandwiched by the sandwiching claws 32. The pair of guard wall portions 37 are opposed to each other in the width direction WD, and are symmetrical with respect to the center line of the bracket main body portion 31 in the width direction WD. Each guard wall 37 is inclined toward the center of the bracket body 31 in the width direction WD as it goes in the insertion direction ID.

  In addition, as shown in FIGS. 5 and 7, the top portion 38 of the guard wall portion 37 is closer to the magnet holder 50 than the top portion 44 of the peripheral wall portion 43 in the standing direction SD along the rotation axis RAL of the magnet holder 50. The height is defined to be separated. Thereby, the guard wall part 37 can be located avoiding the rotation track of the magnet holder 50.

  Further, as shown in FIGS. 1 and 6, the intermediate portion in the extending direction of the clamping claw portion 32 projects outward from the outer edge portion of the housing 40 in the width direction WD. Moreover, the intermediate part of the clamping claw part 32 is located inside the outer edge part of the guard wall part 37 in the width direction WD. Further, the guide wall portion 33 is located outside the housing 40 in the width direction WD and located inside the intermediate portion of the clamping claw portion 32. As described above, the outer edge dimensions W1, W2, and W3 in the width direction WD are opposite to the insertion direction ID in the guide wall portion 33, the clamping claw portion 32, and the guard wall portion 37 that are aligned in the insertion direction ID. It is made small in order as it goes to.

  A process of assembling the liquid level detection module 100 having the above configuration to the fuel tank 90 will be described with reference to FIG. First, the bracket plate 30 is inserted from the outside to the inside of the fuel tank 90 through the opening 95 along the insertion direction ID. Thereby, the bracket plate 30 holding the fuel sender 10 gradually passes through the opening 95 from the guard wall portion 37 side. As described above, the fuel sender 10 and the bracket plate 30 are accommodated in the fuel tank 90. The liquid level detection module 100 is fixed to the fuel tank 90 by being attached to the ceiling portion 93 so that the lid 20 is in liquid tight contact with the peripheral portion 96.

  Functions of the guard wall portion 37 and the like in the above steps will be described with reference to FIG. As shown in FIG. 8A, when the bracket plate 30 is inserted into the opening 95, the insertion position may deviate from the center of the opening 95. In such a case, the guard wall portion 37 positioned in the insertion direction ID with respect to the housing 40 can contact the peripheral portion 96 of the opening 95 before the housing 40. Therefore, the housing 40 is protected by the guard wall portion 37.

  Further, the guard wall portion 37 that is inclined with respect to the insertion direction ID receives a reaction force RF directed toward the center of the opening 95 by contacting the peripheral portion 96 of the opening 95. Therefore, the insertion position of the liquid level detection module 100 can be corrected toward the center of the opening 95.

  In addition, it is assumed that the insertion position of the liquid level detection module 100 is shifted along the width direction WD after the guard wall portion 37 passes through the opening 95 as shown in FIG. 8B. Even in this case, the clamping claws 32 projecting outward from the housing 40 come into contact with the peripheral portion 96 of the opening 95 before the housing 40. Therefore, the housing 40 is protected.

  Furthermore, it is assumed that the insertion position of the liquid level detection module 100 is shifted along the width direction WD after the clamping claw portion 32 passes through the opening 95 as shown in FIG. 8C. Even in this case, the guide wall portion 33 positioned outside the housing 40 contacts the peripheral portion 96 of the opening 95 before the housing 40. Therefore, the housing 40 is protected.

  As described so far, in the present embodiment, the housing 40 is protected by the guard wall portion 37, so that damage to the fuel sender 10 when the liquid level detection module 100 is assembled to the fuel tank 90 can be avoided with a simple configuration. It becomes.

  In addition, in the present embodiment, since the reaction force RF in the direction of correcting the insertion position can act on the guard wall portion 37, the guard wall portion 37 has the effect of avoiding damage to the fuel sender 10 and the liquid level detection module 100. The effect of facilitating the process of inserting the into the opening 95 can also be exhibited.

  Further, according to the present embodiment, not only the guard wall portion 37 but also the sandwiching claw portion 32 and the guide wall portion 33 can exhibit the protective action of the housing 40. In this way, the configuration for the other functions of holding the housing 40 and assisting the mounting of the housing 40 exerts a protective action, so that the configuration of the liquid level detection module 100 is complicated and the fuel sender 10 is damaged during the assembly. Both can be reliably avoided.

  Furthermore, in this embodiment, the dimensions W1, W2, and W3 in the width direction WD of the guard wall portion 37, the clamping claw portion 32, and the guide wall portion 33 that sequentially pass through the opening 95 are narrowly defined in this order. Therefore, the situation where the nail claw 32 is caught by the peripheral portion 96 after the guard wall portion 37 passes through the opening 95 and the situation where the guide wall 33 is caught by the peripheral portion 96 after the holding claw 32 passes through the opening 95 are: Both can be suppressed. As described above, even in the liquid level detection module 100 including the bracket plate 30 that can protect the fuel sender 10, the workability of inserting the plate 30 into the opening 95 is maintained high.

  In addition, according to the present embodiment, the guard wall portion 37 can be positioned out of the rotation orbit of the magnet holder 50. Therefore, even if the guide wall portion 37 is provided in order to avoid damage to the fuel sender 10, a situation in which the rotation of the magnet holder 50 is prevented is avoided.

  In addition, according to the present embodiment, the housing 40 which is pushed down in the insertion direction ID by the inclined portion 36 and whose relative displacement in the direction opposite to the insertion direction ID is restricted by the restriction portion 35 is relative to the bracket plate 30. The relative position can be accurately defined. Thus, by holding the housing 40 at the correct position of the bracket plate 30, the protective action of the housing 40 by the guard wall portion 37 can be surely exhibited. Therefore, the reliability of avoiding damage to the fuel sender 10 is improved.

  In the above embodiment, the fuel sender 10 corresponds to the “liquid level detector” described in the claims, the bracket plate 30 corresponds to the “fixing member” described in the claims, and the guide wall portion. 33 corresponds to the “extending wall portion” described in the claims, the bracket body portion 31 corresponds to the “extending body portion” described in the claims, and the guard wall portion 37 corresponds to the claims. The housing 40 corresponds to the “support” described in the claims, and the bottom wall 41 corresponds to the “support bottom wall” described in the claims. The magnet holder 50 corresponds to the “rotor” described in the claims, and the fuel tank 90 corresponds to the “container” described in the claims.

(Other embodiments)
As mentioned above, although one embodiment by the present invention was described, the present invention is not interpreted limited to the above-mentioned embodiment, and is applied to various embodiments and combinations within the range which does not deviate from the gist of the present invention. be able to.

  In the said embodiment, a pair of guard wall part 37 was a form which inclines toward the outer side from the inner side of the width direction WD as it goes to the opposite direction to insertion direction ID. However, the form of the guard wall portion 37 is not limited to the above form, and may be changed as appropriate. For example, a flat guard wall that extends along the width direction WD may be provided at the tip of the bracket body. In addition, the guard wall portion may not be flat, and may be, for example, a shape that is curved along the outer peripheral edge of the magnet holder or a shape that is bent along the outer edge of the housing.

  In the above embodiment, the top portion 38 of the guard wall portion 37 is defined at a position farther from the magnet holder 50 than the top portion 44 of the peripheral wall portion 43. However, if interference with the magnet holder 50 can be avoided, the position of the top portion of the guard wall portion may be closer to the magnet holder 50 than the top portion of the peripheral wall portion. Or the interference between a guard wall part and a magnet holder may be avoided by forming a notch in a guard wall part.

  In the above embodiment, the two pairs of clamping claws 32 facing the width direction WD are arranged in the insertion direction ID. However, the position, shape, and arrangement of the clamping claws may be changed as appropriate. For example, one clamping nail part extended from a bracket main-body part may be the form which clamps a housing in cooperation with a bracket main-body part by latching a bottom wall part. In addition, a part of the clamping claw portion may be located outside the outer edge portion of the guard wall portion in the width direction WD.

  In the above embodiment, the form of the guide wall portion 33 that assists the attachment of the fuel sender 10 to the bracket plate 30 may be changed as appropriate. For example, the guide wall part may be located outside the outer edge part of the guard wall part and the outer edge part of the clamping claw part in the width direction WD. Further, the guide wall portion 33 may be omitted.

  In the above embodiment, the restricting portion 35 bent with respect to the bracket main body portion 31 restricts the relative displacement of the housing in the direction opposite to the insertion direction ID. The form of the restricting portion may be appropriately changed as long as the relative displacement of the housing 40 can be restricted. In addition, the restricting portion may be omitted if the relative displacement of the housing 40 can be reliably restricted, for example, by clamping with the clamping claws.

  In the above-described embodiment, the fuel sender 10 is configured to realize the detection of the fuel liquid level by measuring the rotation angle of the magnet holder 50 by the Hall IC 60. However, the fuel sender is not of the magnetoelectric conversion type as in the above embodiment, for example, by measuring the electric resistance value that increases or decreases due to the rotation of the rotating body, to realize the detection of the fuel level. An electric resistance type may be used.

  As described above, the present invention has been described based on the example applied to the liquid level detection module that detects the height of the liquid level of the fuel stored in the fuel tank 90 of the vehicle. However, the application target of the present invention is the liquid level of the fuel. It is not limited to height detection. The present invention can be applied to a liquid level detection module in a container of other liquids mounted on the vehicle, such as brake fluid, engine cooling water, and engine oil. Furthermore, the present invention may be applied not only to vehicles but also to liquid level detection modules in containers provided in various consumer devices and various transport machines.
