Description

[Technical field]

[0001] The present invention relates to an injector clip and an injector mounting structure. [Background technology]

[0002] Generally, there is an injector clip that holds an injector that injects fuel into an engine. Patent Document 1 discloses a support clamp that is formed by punching a plate material with a press and bending the punched material into a predetermined shape. The support clamp described in Patent Document 1 has a rotation stopper protrusion that extends upward from the main surface.

[0003] Patent Document 2 discloses a clip for a fuel injection valve including a load transmission member formed from a single wire and a fitting member formed separately from the load transmission member. The load transmission member of the clip for a fuel injection valve described in Patent Document 2 has an abutting portion extending linearly in the y direction, a spring portion, and a pressed portion. The spring portion is formed so as to connect the pressed portion from one end of the abutting portion upward. The pressed portion is located at the apex of the mountain shape, i.e., the maximum point, directly above the middle portion of the abutting portion. The fitting member of the clip for a fuel injection valve described in Patent Document 2 has a plate shape extending in the z direction, and a fitting end portion that can be fitted into the fitted portion of the connection pipe is formed at the end in the positive z direction.

[0004] For example, as described in Patent Documents 1 and 2, injector clips that hold injectors generally have various functional parts that protrude outward, such as a part that stops the rotation of the injector clip and the injector, a part that is pressed against a connecting pipe or the like and elastically deforms to apply a biasing force, and a part that fits into the connecting pipe or the like.

[0005] However, if the injector clip is formed to protrude outward, there is a risk that the injector clip may be displaced from its correct position or come off from the injector if, for example, an operator's hand comes into contact with the injector clip during operation. If the injector clip is displaced from its correct position or comes off from the injector, the injector may be displaced from its correct position. [Prior art documents] [Patent documents]

[0006] [Patent Document 1] JP 2010-168965 A [Patent Document 2] JP 2016-180321 A Summary of the Invention [Problem to be solved by the invention]

[0007] The present invention has been made in consideration of the above-mentioned circumstances, and has an object to provide an injector clip and an injector mounting structure that can prevent the injector clip from being displaced from its correct position or coming off the injector due to a worker's hand or the like coming into contact with the injector clip during operation. [Means for solving the problem]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0012] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. The embodiments described below are preferred specific examples of the present invention, and therefore various technically preferable limitations are applied to them, but the scope of the present invention is not limited to these aspects unless otherwise specified in the following description to the effect that the present invention is limited to them. In addition, in each drawing, similar components are given the same reference numerals, and detailed descriptions thereof are omitted as appropriate.

[0013] FIG. 1 is a plan view showing an injector mounting structure according to the present embodiment. FIG. 2 is a cross-sectional view taken along the line AA in FIG. FIG. 3 is a cross-sectional view taken along the cutting plane BB shown in FIG. FIG. 4 is an exploded view showing the injector mounting structure according to this embodiment.

[0014] The injector mounting structure 2 according to this embodiment includes a fuel supply pipe 3, an injector clip 4, and an injector 5.

[0015] The fuel supply pipe 3 has a rail 31 and a cup 32. As shown in Fig. 2 and Fig. 3, the rail 31 is formed, for example, in a rectangular tube shape, and distributes high-pressure fuel supplied from a fuel pump to a plurality of paths according to the number of cylinders of the engine (internal combustion engine) 6. Figs. 1 to 3 show one of the plurality of paths. The cup 32 is formed in a cylindrical shape, and is attached to the bottom surface of the rail 31. In other words, the cup 32 is provided so as to protrude from the bottom surface of the rail 31 toward the engine 6.

[0016] The injector 5 is provided between the fuel supply pipe 3 and the engine 6. Specifically, as shown in FIG. 2, a portion of the injector 5 near the fuel inlet 51 is inserted into the cup 32 and is in close contact with the inner surface 321 of the cup 32 via an O-ring 541. That is, the portion of the injector 5 near the fuel inlet 51 is connected to the cup 32. Also, a portion of the injector 5 near the injection hole 52 is inserted into a mounting hole 61 of the engine 6 and is in close contact with the inner surface 611 of the mounting hole 61 via an O-ring 542. That is, the portion of the injector 5 near the injection hole 52 is connected to the engine 6.

[0017] The fuel supply pipe 3 distributes the fuel supplied from the fuel pump to multiple paths through a rail 31, and supplies the fuel to an injector 5 connected to a cup 32. The injector 5 opens and closes a needle valve, for example, by a solenoid, based on a signal input from an electronic control unit (ECU) to a connector 53, and injects the fuel supplied from the fuel supply pipe 3 into the engine 6 from an injection hole 52.

[0018] The injector clip 4 is attached to the injector 5 and the cup 32, and holds the injector 5 to maintain the injector 5 attached to the cup 32 of the fuel supply pipe 3. As shown by an arrow A1 in FIG. 4, the injector clip 4 is first attached to the outer periphery of the injector 5. Specifically, the injector clip 4 fits into a groove 55 provided on the outer periphery of the injector 5. The direction of the arrow A1 in FIG. 4 is an example of the "attachment direction" of the present invention. Next, as shown by an arrow A2 in FIG. 4, the injector 5 is attached to the cup 32 of the fuel supply pipe 3 with the injector clip 4 attached to the injector 5. Specifically, as shown in FIG. 3 and FIG. 4, the flange 323 of the cup 32 extends from the cylindrical outer surface 324 of the cup 32 toward the outside in the radial direction, and fits into the second hole 433 formed in the injector clip 4. In this manner, the injector clip 4 retains the injector 5 and keeps the injector 5 attached to the cup 32 of the fuel supply tube 3 .

[0019] Next, the injector clip 4 according to this embodiment will be described with reference to the drawings. FIG. 5 is a perspective view showing the injector clip according to the present embodiment. FIG. 6 is a perspective view showing the injector clip according to the present embodiment. FIG. 7 is a top view showing the injector clip according to the present embodiment. FIG. 8 is a side view showing the injector clip according to the present embodiment. FIG. 9 is a rear view showing the injector clip according to the present embodiment. FIG. 10 is a bottom view showing the injector clip according to the present embodiment.

[0020] Fig. 7 corresponds to a plan view of the injector clip 4 when viewed in the direction of the arrow A4 shown in Fig. 5. Fig. 8 corresponds to a plan view of the injector clip 4 when viewed in the direction of the arrow A5 shown in Fig. 5. Fig. 9 corresponds to a plan view of the injector clip 4 when viewed in the direction of the arrow A1 shown in Fig. 5. Fig. 10 corresponds to a plan view of the injector clip 4 when viewed in the direction of the arrow A2 shown in Fig. 5.

[0021] As described above with reference to FIG. 4, the direction of the arrow A1 is an example of the "attachment direction" of the present invention. The direction of the arrow A3 is the opposite direction to the arrow A1, and is an example of the "opposite direction" of the present invention. The directions of the arrows A2 and A4 are perpendicular to the surface 411 of the base 41 of the injector clip 4, and are an example of the "vertical direction" of the present invention. As described above with reference to FIG. 4, the direction of the arrow A2 is the insertion direction of the injector 5 into the cup 32. The directions of the arrows A5 and A6 are parallel to the surface 411 of the base 41 of the injector clip 4 and perpendicular to the directions of the arrows A1 and A3. That is, the directions of the arrows A5 and A6 are perpendicular to the directions of the arrows A1 and A3, and perpendicular to the directions of the arrows A2 and A4.

[0022] The injector clip 4 is formed, for example, by pressing a metal plate. However, the method of forming the injector clip 4 is not limited to this. As shown in Figs. 5 to 7, the injector clip 4 has a base 41. The base 41 is a portion that is attached to the outer periphery of the injector 5, and has an opening 412 and a passing portion 413. The opening 412 is formed by penetrating the center of the base 41. The passing portion 413 spatially connects the opening 412 and the outside of the base 41, and is formed to allow the outer periphery of the injector 5 to pass through.

[0023] When base 41 is inserted into groove 55 (see FIG. 4) of injector 5 in the direction of arrow A1 (i.e., the mounting direction), bottom 551 (see FIG. 4) of groove 55 of injector 5 passes through passing portion 413 of injector clip 4. At this time, passing portion 413 of injector clip 4 expands in the directions of arrows A5 and A6. Bottom 551 of groove 55 of injector 5 passes through passing portion 413 of injector clip 4 and fits into opening 412. In this way, base 41 of injector clip 4 fits into groove 55 provided on the outer periphery of injector 5, and is mounted to injector 5.

[0024] Here, as shown in FIG. 7 and FIG. 10, the diameter R1 of the first round portion 414 of the base 41 formed at the boundary between the opening 412 and the passing portion 413 is smaller than the diameter R2 of the second round portion 415 of the base 41 formed at the boundary between the outside of the base 41 and the passing portion 413. In other words, the diameter R2 of the second round portion 415 of the base 41 is larger than the diameter R1 of the first round portion 414 of the base 41. As a result, the bottom portion 551 of the groove 55 of the injector 5 is guided by the second round portion 415 and easily passes through the passing portion 413 of the injector clip 4, and is easily fitted into the opening 412. On the other hand, since the diameter R1 of the first round portion 414 is smaller than the diameter R2 of the second round portion 415, the bottom portion 551 of the groove 55 of the injector 5 is difficult to come out of the opening 412 once it is fitted into the opening 412. In other words, the base 41 of the injector clip 4 can be prevented from easily coming out of the groove 55 of the injector 5.

[0025] As shown in FIG. 5 and FIG. 6, the injector clip 4 has a first side portion 42 and a second side portion 43. The first side portion 42 is connected to the base portion 41 on one side with respect to the mounting direction of the base portion 41 (i.e., the direction of the arrow A1), and extends from a connection portion on one side of the base portion 41 in a direction perpendicular to the surface 411 of the base portion 41 (in the present embodiment, the direction of the arrow A2). In the present embodiment, the one side with respect to the mounting direction of the base portion 41 is the direction of the arrow A5. That is, the first side portion 42 is connected to a side end of the base portion 41 in the direction of the arrow A5. The second side portion 43 is connected to the base portion 41 on the other side with respect to the mounting direction of the base portion 41, and extends from a connection portion on the other side of the base portion 41 in a direction perpendicular to the surface 411 of the base portion 41 (in the present embodiment, the direction of the arrow A2). In the present embodiment, the other side with respect to the mounting direction of the base portion 41 is the direction of the arrow A6. That is, the second side portion 43 is connected to the side end of the base portion 41 in the direction of the arrow A6.

[0026] The first side portion 42 has a first side wall portion 421 and a first enlarged portion 422. The first side wall portion 421 is connected to the base portion 41 on one side with respect to the mounting direction of the base portion 41, and is a portion extending from the connection portion on one side of the base portion 41 in a direction perpendicular to the surface 411 of the base portion 41. As shown in FIG. 5, the first side wall portion 421 has a first hole portion 423. The first hole portion 423 is formed extending along the directions of the arrows A1 and A3, and penetrates the first side wall portion 421. As shown in FIG. 5 and FIG. 9, the first enlarged portion 422 is connected to an end portion (i.e., the upper end) of the first side wall portion 421 in the direction of the arrow A2, and extends so as to enlarge in the direction of the arrow A5 as it moves away from the first side wall portion 421.

[0027] The second side portion 43 has a second side wall portion 431 and a second enlarged portion 432. The second side wall portion 431 is connected to the base portion 41 on the other side with respect to the mounting direction of the base portion 41, and is a portion extending from the connection portion on the other side of the base portion 41 in a direction perpendicular to the surface 411 of the base portion 41. As shown in FIG. 6, the second side wall portion 431 has a second hole portion 433. The second hole portion 433 is formed extending along the directions of the arrows A1 and A3, and penetrates the second side wall portion 431. As shown in FIG. 6 and FIG. 9, the second enlarged portion 432 is connected to the end (i.e., the upper end) of the second side wall portion 431 in the direction of the arrow A2, and extends so as to widen in the direction of the arrow A6 as it moves away from the second side wall portion 431.

[0028] 5 to 10, the injector clip 4 has a back portion 44. The back portion 44 is connected to the first side portion 42 and the second side portion 43, and extends along a direction perpendicular to the surface 411 of the base portion 41 of the injector clip 4 (i.e., the direction of the arrow A2 and the direction of the arrow A4). The back portion 44 may be connected to the base portion 41.

[0029] As shown in FIG. 5, FIG. 6, and FIG. 9, the back portion 44 has a recess 441 formed in a central portion 446. The back portion 44 also has a fitting portion 445. The fitting portion 445 is provided at an end of the back portion 44 in the direction of the arrow A4, and has a first claw portion 442 and a second claw portion 443. The end of the back portion 44 in the direction of the arrow A4 is an example of the "one end in the vertical direction" of the present invention. As shown in FIG. 8, the first claw portion 442 and the second claw portion 443 are bent at an acute angle from the direction of the arrow A4 at the end of the back portion 44 in the direction of the arrow A4 and extend. Also, as shown in FIG. 6 and FIG. 10, the first claw portion 442 and the second claw portion 443 are separated from each other in the directions of the arrows A5 and A6. Therefore, a gap 444 is formed between the first claw portion 442 and the second claw portion 443.

[0030] 1, when the injector clip 4 is attached to the injector 5, that is, when the base 41 of the injector clip 4 fits into the groove 55 of the injector 5, the protrusion 56 protruding outward from the outer surface of the injector 5 fits into the gap 444 between the first claw portion 442 and the second claw portion 443. This prevents the injector clip 4 from rotating relative to the injector 5.

[0031] 4, the injector 5 is attached to the cup 32 of the fuel supply pipe 3 with the injector clip 4 attached to the injector 5. At this time, the first expanded portion 422 extends so as to widen in the direction of the arrow A5 as it moves away from the first side wall portion 421, and the second expanded portion 432 extends so as to widen in the direction of the arrow A6 as it moves away from the second side wall portion 431. Therefore, an operator can easily attach the injector 5 to the cup 32 of the fuel supply pipe 3 with the injector clip 4 attached to the injector 5. Then, the flange portion 323 of the cup 32 fits into the first hole portion 423 formed in the first side wall portion 421 and the second hole portion 433 formed in the second side wall portion 431.

[0032] At this time, as shown in FIG. 1 and FIG. 2, the protrusion 322 of the cup 32 extends radially outward from the cylindrical outer surface 324 of the cup 32 and fits into a recess 441 formed in the back portion 44 of the injector clip 4. The protrusion 322 is a portion that extends further radially outward from the cylindrical outer surface 324 of the cup 32 compared to the flange portion 323. The protrusion 322 of the cup 32 fits into the recess 441 of the injector clip 4, thereby suppressing rotation of the injector clip 4 relative to the cup 32. As a result, the rotation of the injector 5 relative to the cup 32 is suppressed by the injector clip 4. In this way, the injector clip 4 holds the injector 5 and maintains a state in which the injector 5 is attached to the cup 32 of the fuel supply pipe 3.

[0033] Here, as shown in FIG. 2 and FIG. 3, when the injector clip 4 holds the injector 5 and the injector 5 is attached to the cup 32 of the fuel supply pipe 3, the connector 53 of the injector 5 is present near the injector clip 4. For this reason, for example, if the injector clip is formed to protrude outward, the worker's hand may come into contact with the injector clip when connecting the harness to the connector. This may cause the injector clip to be displaced from its correct position or to come off from the injector. If the injector clip is displaced from its correct position or to come off from the injector, the injector may be displaced from its correct position. The risk of the worker's hand coming into contact with the injector clip during work may occur not only when the worker is connecting the harness to the connector, but also during other work.

[0034] In contrast, as shown in FIG. 5 and FIG. 8, each of the first side portion 42 and the second side portion 43 of the injector clip 4 according to this embodiment has a notch portion 451. The notch portion 451 is formed at an end portion in the mounting direction (i.e., the direction of the arrow A1) of the extension end portion in the direction in which each of the first side portion 42 and the second side portion 43 extends from the connection portion of the base portion 41 (the direction of the arrow A2 in this embodiment). The notch portion 451 is formed in a direction inclined with respect to the vertical direction of the surface 411 of the base portion 41. This makes it possible to prevent the hand of the worker from touching the injector clip 4 when the worker is working to connect the harness to the connector 53. This makes it possible to prevent the injector clip 4 from being displaced from the correct position or coming off the injector 5 due to the hand of the worker or the like touching the injector clip 4 during the work.

[0035] As shown in FIG. 5 and FIG. 8, each of the first side portion 42 and the second side portion 43 of the injector clip 4 according to this embodiment has a notch portion 452. The notch portion 452 is formed at an end portion of the first side portion 42 and the second side portion 43 in a direction in which the first side portion 42 and the second side portion 43 extend from the connection portion of the base portion 41 (in the direction of the arrow A2 in this embodiment) in the opposite direction to the mounting direction (i.e., the direction of the arrow A3). The notch portion 452 is formed in a round shape (i.e., a circular shape) at an end portion of the first side portion 42 and the second side portion 43 in the opposite direction to the mounting direction in the extension end portion. Therefore, when an operator works at a position opposite to the position of the connector 53, the operator's hand can be prevented from coming into contact with the injector clip 4. This can prevent the injector clip 4 from being displaced from the correct position or coming off the injector 5 due to the operator's hand or the like coming into contact with the injector clip 4 during work.

[0036] As described above, when the bottom 551 of the groove 55 of the injector 5 passes through the passing portion 413 of the injector clip 4, the passing portion 413 of the injector clip 4 expands in the directions of the arrows A5 and A6. Specifically, the first side portion 42 in the vicinity of the passing portion 413 moves in the direction of the arrow A5, and the second side portion 43 in the vicinity of the passing portion 413 moves in the direction of the arrow A6. Therefore, the central portion 446 of the back portion 44 is subjected to bending stress. Therefore, if an attempt is made to ensure the dimension L11 (see FIG. 9) in the vertical direction (i.e., the direction of the arrows A2 and A4) of the central portion 446 of the back portion 44 while ensuring the depth of the recess 441 for the projection 322 of the cup 32 to be securely fitted into the recess 441 of the back portion 44, there is a risk that the first claw portion 442 and the second claw portion 443 cannot face the surface of the projection 56 of the injector 5. If the first claw portion 442 and the second claw portion 443 cannot face the surface of the protrusion 56 of the injector 5, the protrusion 56 of the injector 5 cannot fit into the gap 444 between the first claw portion 442 and the second claw portion 443.

[0037] In contrast, the first claw portion 442 and the second claw portion 443 are bent at an acute angle from the direction of the arrow A4 at the end of the back portion 44 in the direction of the arrow A4 and extend. Therefore, the first claw portion 442 and the second claw portion 443 can reliably face the surface of the protrusion portion 56 of the injector 5 while ensuring the depth of the recessed portion 441 for reliably fitting the protrusion portion 322 of the cup 32 into the recessed portion 441 of the back portion 44 and while ensuring the vertical dimension L11 of the central portion 446 of the back portion 44. Therefore, the protrusion portion 56 of the injector 5 can reliably fit into the gap 444 between the first claw portion 442 and the second claw portion 443. As a result, the fitting portion 445 can exert a function of preventing the injector clip 4 from rotating relative to the injector 5 while ensuring the depth of the recessed portion 441 of the back portion 44 and while ensuring the vertical dimension L11 of the central portion 446 of the back portion 44.

[0038] Next, the injector mounting structure according to this embodiment will be further described with reference to the drawings. FIG. 11 is a cross-sectional view taken along the cutting plane CC shown in FIG. FIG. 12 is a cross-sectional view taken along the cutting plane DD shown in FIG.

[0039] 5 to 10, when the injector 5 is attached to the cup 32 of the fuel supply pipe 3 with the injector clip 4 attached to the injector 5, the flange 323 of the cup 32 fits into the first hole 423 formed in the first side wall 421 of the first side 42 and the second hole 433 formed in the second side wall 431 of the second side 43. At this time, the first side 42 and the second side 43 are separated from the flange 323 of the cup 32 at both ends in the directions in which the first hole 423 and the second hole 433 extend (i.e., the directions of the arrows A1 and A3).

[0040] Specifically, as shown in FIG. 11, at the end of the first hole 423 in the direction of the arrow A1, a gap of distance L1 is generated between the first side wall 421 of the first side 42 and the flange 323 of the cup 32. At the end of the first hole 423 in the direction of the arrow A3, a gap of distance L2 is generated between the first side wall 421 of the first side 42 and the flange 323 of the cup 32. At the end of the second hole 433 in the direction of the arrow A1, a gap of distance L3 is generated between the second side wall 431 of the second side 43 and the flange 323 of the cup 32. At the end of the second hole 433 in the direction of the arrow A3, a gap of distance L4 is generated between the second side wall 431 of the second side 43 and the flange 323 of the cup 32.

[0041] This allows flange 323 of cup 32 to come into contact with first side portion 42 and second side portion 43 at both ends in the direction in which first hole portion 423 and second hole portion 433 extend, and prevents the injector clip 4 from climbing up onto first side portion 42 and second side portion 43. This prevents injector clip 4 from shifting from its correct position or coming off injector 5 due to the worker's hand or the like coming into contact with injector clip 4 during work.

[0042] 11 and 12, distances L1 to L4 between the first side portion 42 and the second side portion 43 at both ends of the first hole portion 423 and the second hole portion 433 and the flange portion 323 of the cup 32 are longer than distances L5 and L6 between the inner edge 416 (see FIGS. 7 and 10) of the opening 412 of the base 41 and the outer periphery of the injector 5. Specifically, distance L5 between the inner edge 416 of the opening 412 of the base 41 connected to the first side portion 42 and the bottom 551 of the groove 55 of the injector 5 is shorter than distances L1 to L4 between the first side portion 42 and the second side portion 43 at both ends of the first hole portion 423 and the second hole portion 433 and the flange portion 323 of the cup 32. Further, the distance L6 between the inner edge 416 of the opening 412 of the base 41 connected to the second side portion 43 and the bottom 551 of the groove 55 of the injector 5 is shorter than the distances L1 to L4 between each of the first side portion 42 and the second side portion 43 at both ends of the first hole portion 423 and the second hole portion 433 and the flange portion 323 of the cup 32.

[0043] According to this, when the injector clip 4 moves due to contact with the hand of an operator during work, the bottom 551 of the groove 55 of the injector 5 comes into contact with the inner edge 416 of the opening 412 of the base 41 before the flange 323 of the cup 32 comes into contact with the first side portion 42 and the second side portion 43 at both ends of the first hole portion 423 and the second hole portion 433. Therefore, even when the injector clip 4 moves, the flange 323 of the cup 32 comes into contact with the first side portion 42 and the second side portion 43 at both ends in the extension direction of the first hole portion 423 and the second hole portion 433, and can be prevented from riding up onto the first side portion 42 and the second side portion 43. This makes it possible to more reliably prevent the injector clip 4 from being displaced from the correct position or coming off the injector 5 due to contact with the hand of an operator during work.

[0044] The above describes the embodiments of the present invention. However, the present invention is not limited to the above embodiments, and various modifications can be made without departing from the scope of the claims. The configurations of the above embodiments can be partially omitted or arbitrarily combined in a manner different from the above. [Explanation of symbols]
