Description

Sensor bracket Technical Field

[0001] This invention relates to a sensor bracket for mounting a sensor to a vehicle body. Background Technology

[0002] JP2020-91259A discloses a bracket for mounting a radar to a vehicle body. The bracket includes: a positioning part that abuts against a side edge of the radar; a pressing part that presses another side edge of the radar toward the positioning part; and a plurality of engaging parts that engage two edges of the radar to prevent the radar from detaching from the bracket.

[0003] Because the bracket disclosed in JP2020-91259A has multiple joints on either side of the positioning part and the pressing part, the position of the radar relative to the bracket is not as secure or accurate as expected. Summary of the Invention

[0004] In view of these problems in the prior art, the main objective of the present invention is to provide a sensor holder that can support the sensor with high precision.

[0005] To achieve this objective, one aspect of the invention provides a sensor bracket (1) for mounting a sensor (2) to a vehicle body, comprising: a base wall (10) opposite to the rear surface of the sensor; at least one first positioning portion (25) protruding from the base wall and abutting against a side edge of the sensor in a first direction extending along the base wall; at least one first pressing portion (26) protruding from the base wall and pressing the sensor against the first positioning portion in the first direction; and a first engaging portion (27) protruding from the base wall and engaging the sensor to resist movement of the sensor away from the base wall, the first engaging portion being disposed in the first direction between the at least one first positioning portion and the at least one pressing portion.

[0006] Since the first engagement portion engages the sensor at a position located between at least one first positioning portion and at least one first pressing portion along the first direction, the sensor can be accurately supported by the bracket.

[0007] Preferably, in this sensor bracket, the sensor includes a sensor body (4) and a connector (5-7) extending along the base wall in a second direction intersecting the first direction, and one of the at least one first positioning portion or one of the at least one first pressing portion abuts against the side edge of the connector.

[0008] Since one of the at least one first positioning part or one of the at least one first pressing part abuts against the side edge of the connector rather than the side edge of the sensor body, the positioning function of the at least one of the at least one first positioning part or one of the at least one first pressing part can be improved.

[0009] Preferably, in this sensor bracket, the connecting member is disposed along the first direction between the at least one first pressing portion and the at least one first positioning portion.

[0010] As a result, the sensor can be supported by the bracket with exceptional accuracy.

[0011] Preferably, in this sensor bracket, one of the at least one first positioning portion, one of the at least one first pressing portion, and the side edges of the first connector are substantially aligned with each other along the first direction.

[0012] As a result, the sensor can be supported by the bracket in a particularly stable manner.

[0013] Preferably, in this sensor bracket, the connecting member includes a first connecting member (5) and a second connecting member (6) arranged in a spaced-apart relationship along the first direction, and one of the at least one first pressing part presses against the first connecting member, while one of the at least one first positioning part abuts against the second connecting member.

[0014] As a result, the sensor can be supported by the bracket in a particularly accurate and stable manner.

[0015] Preferably, in this sensor bracket, the sensor further includes a third connector (7) and a second engagement portion, the third connector extending from the side of the sensor body opposite to the first connector and the second connector, and the second engagement portion extending from the base wall to engage the third connector against movement of the sensor away from the base wall.

[0016] As a result, the sensor can be supported by the bracket in a particularly accurate and stable manner.

[0017] Preferably, in this sensor holder, the first engagement portion includes a pair of first engagement portions disposed in a spaced-apart relationship along the first direction between one of the at least one first positioning portion and one of the at least one first pressing portion, and the sensor is substantially restricted from moving away from the base wall only at three points by the first engagement portions and the second engagement portions.

[0018] By restricting the sensor's movement away from the base wall at essentially three points, the position of the sensor's front surface, especially its angular position, can be made both stable and accurate.

[0019] Preferably, in this sensor bracket, each of the first, second, and third connectors has a front surface that retracts from the front surface of the sensor body.

[0020] This allows the joint to be sufficiently robust without protruding substantially from the front surface of the radar.

[0021] Preferably, in this sensor holder, the first engagement portion includes a pillar protruding from the base wall and a claw extending from the end of the pillar along the first direction, and the claw includes an engagement surface facing the base wall and a guide surface extending from the end of the engagement surface to the end of the pillar.

[0022] Therefore, the sensor can be easily engaged with the first engagement part. Due to the presence of a guide surface that can be formed by a curved and / or inclined surface, the sensor can be firmly engaged by the claw or its engagement surface without requiring excessive force to push the sensor into the engaged state.

[0023] Preferably, in this sensor bracket, the at least one first positioning part and the at least one first pressing part are each arranged in pairs and are spaced apart from each other in a second direction that intersects the first direction.

[0024] Therefore, the radar can be positioned in a particularly stable manner in the first direction.

[0025] Preferably, in this sensor bracket, the sensor bracket further includes at least one second positioning part that abuts against the sensor along the second direction, and at least one second pressing part that presses the sensor against the at least one second positioning part along the second direction.

[0026] Therefore, it is possible to properly position the sensor in the second direction.

[0027] Preferably, in this sensor bracket, the at least one second positioning part includes a pair of second positioning parts, and the at least one second pressing part includes a pair of second pressing parts, the pair of second positioning parts respectively abutting against the ends of the first connecting member and the second connecting member.

[0028] Therefore, the radar can be positioned in a particularly stable manner in the second direction.

[0029] Preferably, in this sensor bracket, the base wall is provided with a spring portion, which pushes the sensor away from the base wall.

[0030] By using a spring to elastically press the sensor against the joint, it is possible to achieve, in a particularly advantageous manner, the sensor facing towards and away from the base wall.

[0031] Therefore, the present invention provides a sensor bracket capable of supporting a sensor with high precision.

[0032] Another aspect of the present invention provides a sensor mounting structure comprising a sensor bracket as defined above and a sensor configured to be mounted to the sensor bracket. Attached Figure Description

[0040] Figure 8 is a cross-sectional view taken along line VIII-VIII in Figure 6. Detailed Implementation

[0041] The sensor mounting structure according to an embodiment of the present invention will now be described with reference to the accompanying drawings.

[0042] Figures 1 and 2 show sensor bracket 1, via which sensor 2 is mounted on the vehicle body. Sensor 2 can be radar, camera, LiDAR (light detection and ranging), or sonar. In this embodiment, sensor 2 consists of millimeter-wave radar, but it can also be microwave radar or submillimeter-wave radar.

[0043] Sensor 2 emits radio waves and measures the time it takes for the radio waves to bounce back from objects around the vehicle and the direction in which the radio waves arrive at the radar. This allows the detection of the location of surrounding objects.

[0044] As shown in Figures 1 and 3, the sensor 2 includes a sensor body 4 and three connecting members 5, 6, and 7 extending from the upper and lower edges of the sensor body 4. The sensor body 4 is formed as a flat cuboid member. In this embodiment, the sensor 2 is mounted at the front end of the vehicle, with its main plane extending perpendicular to the vehicle's direction of travel (forward and backward). Although the actual mounting posture of the sensor 2 is not limited to the mounting posture of the illustrated embodiment, this is assumed for ease of description. Furthermore, again for ease of description, the orientation of the sensor can be assumed as indicated in the figures.

[0045] The connectors include a first connector 5 and a second connector 6 that project downwards from either side of the lateral center point of the lower edge of the sensor body 4 in a mutually spaced-apart relationship (symmetrical about the centerline), and a third connector 7 that projects upwards from the lateral center point of the bottom edge of the sensor body 4. Each of the first connector 5, the second connector 6, and the third connector 7 is formed in a plate shape with its main surface facing forward and backward. The first connector 5, the second connector 6, and the third connector 7 (particularly their front surfaces) are disposed on a substantially common plane, which is located midway between the front and rear surfaces of the sensor body 4. More specifically, the front surfaces of the first connector 5, the second connector 6, and the third connector 7 recede or extend backward from the front surface of the sensor body 4. Radio waves are emitted forward from the front surface of the sensor body 4. Similarly, reflected waves are received through the front surface of the sensor body 4.

[0046] The connector portion 8 protrudes rearward from the right end of the sensor body 4. In this case, the connector portion 8 is vertically elongated and has an internal electrical connector for establishing an electrical connection between the sensor 2 and an external circuit (not shown in the figure).

[0047] The sensor bracket 1 can be attached to a structural component of the vehicle body, such as the front bulkhead. Alternatively, the sensor bracket 1 can be attached to an external component of the vehicle body, such as the front grille, the surface of the front bumper, the surface of the rear bumper, etc. In this embodiment, the sensor bracket 1 is attached to the rear surface of the front grille.

[0048] The sensor bracket 1 can be made of a plastic material such as polybutylene terephthalate resin, and is preferably reinforced with glass fiber.

[0049] As shown in Figures 4 and 5, the sensor holder 1 includes a plate-shaped base wall 10 with a rectangular shape facing forward and backward, and a side wall 11 extending forward from the outer edge of the base wall 10. Therefore, the base wall 10 and the side wall 11 together define a receiving recess 12 facing forward and accommodating the sensor 2 therein. The front surface of the base wall 10 faces the rear surface of the sensor 2. A connector opening 14 extends through the right end portion of the base wall 10 for accommodating a connector portion 8 therein. In the mounted state of the sensor 2, the connector portion 8 of the sensor 2 extends rearward through the connector opening 14 towards the base wall 10.

[0050] The sidewall 11 includes a left edge wall 16 and a right edge wall 17 extending vertically along the left and right edges of the base wall 10, respectively. The sidewall 11 also includes an upper edge wall 18 extending horizontally along the upper edge of the base wall 10 between the upper ends of the left edge wall 16 and the right edge wall 17, and a lower edge wall 19 extending horizontally along the lower edge of the base wall 10 between the lower ends of the left edge wall 16 and the right edge wall 17.

[0051] The lower connector 21 extends downward from the lower edge of the base wall 10 at its center. A rectangular opening passes through the lower connector 21. A pair of upper connectors 22 extend upward on either side of a centerline perpendicular to the lower connector 21, spaced laterally. Each upper connector 22 has an opening therethrough. The sensor bracket 1 is attached to the vehicle body at the lower connector 21 and the upper connectors 22. In this embodiment, the lower connector 21 is inserted into a mounting hole formed on the rear side of the front grille, and the upper connector 22 is attached to the rear of the front grille with screws.

[0052] The sensor bracket 1 is provided with a lower first positioning part 25A and an upper first positioning part 25B, which abut against the left side of the sensor 2 to assist in the lateral positioning of the sensor 2. The lower first positioning part 25A is composed of a wall member connected to both the left edge wall 16 and the base wall 10, and has a right edge that evenly abuts against the left edge of the second connector 6. Similarly, the upper first positioning part 25B is composed of a wall member connected to both the left edge wall 16 and the base wall 10, and has a right edge that evenly abuts against the opposite side of the sensor body 4.

[0053] The sensor bracket 1 is provided with a lower first pressing part 26A consisting of a support column 31 or strip extending vertically from the base wall 10. The upper end of the support column 31 is provided with a raised part 32 having a circular surface, which is opposite to the right edge of the first connecting member 5.

[0054] With sensor 2 installed, the lower first pressing part 26A elastically presses against the right edge of the first connecting member 5, while the sensor body 4 itself is supported by the lower first positioning part 25A, which is laterally aligned with the lower first pressing part 26A. Therefore, sensor 2 is laterally and elastically clamped between the lower first pressing part 26A and the lower first positioning part 25A along the same line of action (see line L in FIG. 6).

[0055] The sensor bracket 1 is also provided with an upper first pressing part 26B, which is similar to the lower first pressing part 26A and is composed of a pillar or strip extending vertically from the base wall 10. The upper end of the pillar 31 is provided with a raised part 32 with a circular surface, which is opposite to the right side of the sensor body 4.

[0056] With sensor 2 installed, the upper first pressing part 26B elastically presses against the right side of the sensor body 4 of sensor 2, while the sensor body 4 itself is supported by the upper first positioning part 25B, which is laterally aligned with the upper first pressing part 26B. Therefore, sensor 2 is laterally and elastically sandwiched between the upper first pressing part 26B and the upper first positioning part 25B along the same line of action.

[0057] The base wall 10 is provided with four spring members 57, which are formed by cutting away material from the base wall 10 and are raised away from the base wall 10 (extending from the base wall 10 in the same direction as the side wall 11). These spring members 57 thus form cantilever springs, which push the sensor 2 away from the base wall 10 in the installed state of the sensor 2, as will be described below.

[0058] A pair of first engagement portions 27 protrude vertically from the lower part of the base wall 10 on both sides of the centerline passing through the lower connector 21. The right first engagement portion 27A includes a support post 34 and a claw portion 35 formed at the free end of the support post 34. The right first engagement portion 27A is configured to bend to the left under external load. The claw portion 35 is provided with a guide surface 35B that slopes to the right and downward from the free end of the claw portion 35 and an engagement surface 35A that extends between the lower end of the guide surface 35B and the support post 34. The guide surface 35B is convex in side view, and the engagement surface 35A is substantially perpendicular to the extension direction of the support post 34, and more preferably, the engagement surface is recessed or slightly inclined away from the base wall 10 as it moves from the lower end of the guide surface toward the support post 34.

[0059] The left first joint 27B is structurally similar to the right first joint 27A, but is a mirror image of it with respect to the center line. In other words, the left first joint 27B is provided with a claw 35, which defines a guide surface 35B that slopes to the left and downward from the free end of the claw 35, and a joint surface 35A that extends between the lower end of the guide surface 35B and the support 34.

[0060] The claw portion 35 of the right first engaging portion 27A engages with the left edge of the first connecting member 5. Specifically, the engaging surface 35A of the claw portion 35 of the right first engaging portion 27A engages with the front surface of the first connecting member 5 from the left edge. Similarly, the claw portion 35 of the left first engaging portion 27B engages with the right edge of the second connecting member 6. Specifically, the engaging surface 35A of the claw portion 35 of the left first engaging portion 27B engages with the front surface of the second connecting member 6 from the right edge.

[0061] The first engagement portion 27 is disposed between the first positioning portion 25 and the first pressing portion 26 in the lateral direction (first direction). In particular, the first engagement portion 27 is disposed between the lower first positioning portion 25A and the lower first pressing portion 26A substantially along a single straight line (L) in the lateral direction (first direction).

[0062] Therefore, the first connecting member 5 is positioned in the first direction between the lower first pressing portion 26A and the right first engaging portion 27A. As best shown in FIG7, the right first engaging portion 27A restricts the movement of the first connecting member 5 (sensor 2) away from the base wall 10, but substantially does not restrict the lateral movement of the first connecting member 5 (sensor 2).

[0063] The second connector 6 is positioned in the first direction between the lower first positioning portion 25A and the left first joint portion 27B. As best shown in FIG7, the left first joint portion 27B restricts the movement of the first connector 5 (sensor 2) away from the base wall 10, but substantially does not restrict the lateral movement of the second connector 6 (sensor 2).

[0064] The upper edge wall 18 has a central engagement hole 41, which forms a rod-shaped second engagement portion 42 at the front edge of the upper edge wall 18. The third connector 7 passes upward through the engagement hole 41, thereby restricting the movement of the third connector 7 (sensor 2) away from the base wall 10 due to the engagement between the second engagement portion 42 and the third connector 7.

[0065] (In addition to Figures 4, 5 and 6) Referring to Figure 8, a pair of second positioning portions 51 are formed on both sides of the center line of the lower edge wall 19, and each second positioning portion is formed as a thick wall portion of the lower edge wall 19.

[0066] A third engaging portion 45A protruding forward from the corresponding second positioning portion 51 is provided on the second positioning portion 51 on the right side. A guide surface that slopes backward and upward is provided at the front end of the third engaging portion 45A on the right side. The upper (or rear) end of the guide surface extends to the engaging surface (or undercut surface) facing upward and backward. The right second positioning portion 51 is laterally positioned in the middle between the lower first pressing portion 26A and the right first engaging portion 27A, such that the right second positioning portion 51 abuts against the lower edge or end of the first connecting member 5 when the sensor 2 is installed.

[0067] A third engaging portion 45B protruding forward from the corresponding second positioning portion 51 is provided on the upper left side of the second positioning portion 51. A guide surface that slopes backward and upward is provided at the front end of the third engaging portion 45B on the upper left side. The upper (or rear) end of the guide surface extends to the engaging surface (or undercut surface) facing upward and backward. The left second positioning portion 51 is laterally positioned in the middle between the lower first positioning portion 25A and the left first engaging portion 27B, such that the left second positioning portion 51 abuts against the lower edge or end of the second connecting member 6 when the sensor 2 is installed.

[0068] The engagement surface of the third joint 45 elastically restricts the movement of the sensor 2 away from the base wall 10, but this restrictive force is relatively small and provides virtually no restriction effect when the sensor 2 is installed. The engagement surface of the third joint 45 is mainly provided for the convenience of assembly.

[0069] Below the upper edge wall 18, a pair of second pressing portions 52 are provided on both sides of the centerline. The right second pressing portion 52A includes a support column 54 extending forward from the base wall 10 and a raised portion 55 protruding downward from the front end of the support column 54. The raised portion 55 is provided with a downwardly and rearwardly inclined guide surface. The support column 54 provides elasticity to the right second pressing portion 52A. When the sensor 2 is placed in the receiving recess 12 defined by the side wall 11 and the base wall 10, the raised portion 55 elastically presses the sensor 2 downward, and the sensor 2 is supported from below by the second positioning portion 51. The guide surface helps to insert the sensor 2 into this receiving recess 12.

[0070] The left second pressing part 52B is basically the same as the right second pressing part 52A in both structure and function, and can also be considered as a mirror image of the right second pressing part 52A about the center line.

[0071] The process of mounting sensor 2 to sensor bracket 1 will now be described. The operator first tilts the upper end of sensor body 4 backward and inserts the third connector 7 into the engagement hole 41 of the second engagement portion 42 from below. Then, using the third connector 7 engaged by the second engagement portion 42 as a fulcrum, the operator tilts the lower end of sensor body 4 backward until the first connector 5 is engaged by the right first engagement portion 27A and the second connector 6 is engaged by the left first engagement portion 27B. At this point, the connector portion 8 of sensor 2 passes backward through the connector opening 14 and protrudes backward from the base wall 10. Sensor 2 is pushed forward by four springs 57 and held in place by overcoming the force of the springs 57 through the first engagement portion 27 and the second engagement portion 42. As a result, the front-rear position of sensor 2 relative to sensor bracket 1 can be securely determined.

[0072] When sensor 2 is thus held in the receiving recess 12 of sensor bracket 1, the lower first pressing part 26A presses the first connecting member 5 to the left, and the upper first pressing part 26B presses the sensor body 4 to the left. At the same time, the left end of the second connecting member 6 is supported by the lower first positioning part 25A, and the left end of the sensor body 4 is supported by the upper first positioning part 25B. As a result, the lateral position of sensor 2 relative to sensor bracket 1 (in the first direction) can be firmly determined.

[0073] Furthermore, the right second pressing part 52A and the left second pressing part 52B press downwards on the upper edge of the sensor body 4. The lower edges of the first connecting member 5 and the second connecting member 6 are supported from below by the corresponding second positioning part 51. As a result, the vertical position of the sensor 2 relative to the sensor bracket 1 can be firmly determined (in the second direction).

[0074] In this sensor mounting structure, it is important that the sensor 2 is easily assembled or mounted to the bracket 1. According to the illustrated embodiment, the sensor 2 can be securely placed in the receiving recess 12 simply by inserting the third connector 7 through the engagement hole 41 and overcoming the biasing force of the first engagement portion 27 (provided by its support 34) and the biasing force of the spring member 57 to push the lower part of the sensor 2 into the receiving recess 12. The guide surface 35B of the first engagement portion 27 facilitates this process. Once the sensor 2 is fully received in the receiving recess 12, the spring member 57 pushes the sensor 2 forward, while the engagement between the second engagement portion 42 and the third connector 7, and the engagement between the first and second connectors 5 and 6 and the engagement surfaces 35A of the corresponding first engagement portion 27, restrict the forward movement of the sensor 2. Therefore, the sensor 2 is securely and precisely positioned and held in the front-back direction at essentially only three points (the first connector 5, the second connector 6, and the third connector 7).

[0075] Because the front surfaces of the first connector 5, the second connector 6, and the third connector 7 recede backward relative to the front surface of the sensor body 4, the sensor 2 can be securely held by the first joint 27, which has a relatively robust structure, while minimizing the front-to-back dimensions of the sensor mounting structure.

[0076] Lateral positioning of sensor 2 is achieved by pressing sensor 2 against first positioning part 25 using first pressing part 26. First positioning part 25 and first pressing part 26 do not provide holding force in the front-rear direction, so the holding function of first engaging part 27 and second engaging part 42 is not interfered with by the action of first positioning part 25 and first pressing part 26. Similarly, the lateral holding function of first positioning part 25 and first pressing part 26 of sensor 2 is not interfered with by the holding function of first engaging part 27 and second engaging part 42.

[0077] Since the lower first positioning part 25A and the lower first pressing part 26A are laterally aligned with each other and / or the upper first positioning part 25B and the upper first pressing part 26B are laterally aligned with each other, the sensor 2 can be held laterally in a particularly advantageous manner.

[0078] Vertical positioning of sensor 2 is achieved by pressing sensor 2 against second positioning part 51 using second pressing part 52. Once sensor 2 is in place, second pressing part 52, second positioning part 51, and third engaging part 45 provide essentially no holding force in the front-to-back direction, so that the holding function of first engaging part 27 and second engaging part 42 is not interfered with by the action of second pressing part 52, second positioning part 51, and third engaging part 45. Similarly, the vertical holding function of second pressing part 52 and second positioning part 51 of sensor 2 is not interfered with by the holding function of first engaging part 27 and second engaging part 42.

[0079] The invention has been described with reference to specific embodiments, but the invention is not limited to such embodiments and can be modified in various ways without departing from the scope of the invention.

[0080] For example, in the illustrated embodiment, the first pressing part 26, the first positioning part 25, the second pressing part 52, and the second positioning part 51 are all arranged in pairs, but any one of them may be single or more than two without departing from the general idea of ​​the present invention.

[0081] Furthermore, not all of the constituent elements shown in the above embodiments are essential to the broad concept of the present invention, and they may be appropriately selected, omitted, or substituted without departing from the spirit of the invention.
