Description

Technical Field

[0001] This application relates to the field of force detection technology, and in particular to a force detection device for hand mounting. Background Technology

[0002] In the final assembly process of some equipment, such as vehicles, hundreds or thousands of clips and plugs need to be installed by workers by hand. If the installation force is too great, it will not only increase the labor intensity of workers, but also bring serious quality risks such as loose connections and detachment. Therefore, the problem of hand installation force is also the most common human-machine engineering problem in the trial manufacturing process.

[0003] There are abundant and detailed ergonomic standards for installation force issues. However, in the process of identifying and judging actual problems, the inherent limitations of measuring tools have caused many problems. On-site measurement of installation force mainly relies on handheld push rod force gauges. However, this type of measuring tool can only provide single-point thrust. During the measurement process, the plug rotates under off-center load, causing the guide groove to tighten and jam, which will cause the measured force to increase abnormally, affecting the judgment of installation force problems. Ultimately, the measured force results cannot match the actual feeling, and the measurement accuracy is not high. Utility Model Content

[0055] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0056] It should be noted that when a component is referred to as being "fixed to" or "set on" another component, it can be directly on or indirectly on that other component. When a component is referred to as being "connected to" another component, it can be directly connected to or indirectly connected to that other component.

[0057] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0058] In this specification, references to "one embodiment," "some embodiments," or simply "embodiment" mean that one or more embodiments of this application include a specific feature, structure, or characteristic described in connection with that embodiment. Therefore, the phrases "in one embodiment," "in some embodiments," "in other embodiments," "in still other embodiments," etc., appearing in different parts of this specification do not necessarily refer to the same embodiment, but rather mean "one or more, but not all, embodiments," unless otherwise specifically emphasized. Furthermore, in one or more embodiments, specific features, structures, or characteristics may be combined in any suitable manner.

[0059] To illustrate the technical solution of this application, the following description is provided in conjunction with specific accompanying drawings and embodiments.

[0060] In the final assembly process of some equipment, such as vehicles, hundreds or thousands of clips and plugs need to be installed by workers by hand. If the installation force is too great, it will not only increase the labor intensity of workers, but also bring serious quality risks such as loose connections and detachment. Therefore, the problem of hand installation force is also the most common human-machine engineering problem in the trial manufacturing process.

[0061] There are abundant and detailed ergonomic standards for installation force issues. However, in the process of identifying and judging actual problems, the inherent limitations of measuring tools have caused many difficulties. On-site measurement of installation force mainly relies on handheld push rod force gauges. However, such measuring tools can only provide single-point pushing force. For high-voltage wire harness plugs, which are large in size and have many guides, the operator needs to grasp the plug with the whole palm, align it with the guides, and then push it in. Therefore, the plug rotates under off-center load during the measurement process, causing the guide groove to tighten and jam, which will cause the measured force to increase abnormally and affect the judgment of installation force issues. In addition, since the force is applied by the fingertips or the front of the palm during actual operation, while the measuring tool is applied by the side of the hand, the measured force result cannot match the actual body feeling, resulting in low measurement accuracy.

[0062] In view of this, the present application provides a hand installation force detection device. Since the hand installation force detection device includes a first connector and a second connector connected to each other, the first connector and the second connector are arranged sequentially along a first direction. The first connector and the second connector can move relative to each other in a direction parallel to the first direction. The hand installation force detection device also includes a force sensor located between the first connector and the second connector. The force sensor is in contact with the second connector. Therefore, the first connector can be connected to the finger, and the second connector can be held against the force-receiving component. The force sensor can accurately measure the force applied to the force sensor by the first connector and / or the second connector, thereby measuring the force applied to the second connector by the force-receiving component. In this way, the installation force of the hand on the force-receiving component can be accurately measured by the force sensor.

[0063] Please refer to Figures 1 to 4 , Figure 1 This is a diagram showing the usage state of the hand mounting force detection device 100 in one embodiment of this application. Figure 2 yes Figure 1 Another usage diagram of the hand mounting force detection device 100 shown. Figure 3 yes Figure 2 The corresponding main view, Figure 4 yes Figure 3 The hand mounting force detection device 100 shown is a cross-sectional view along the AA direction.

[0064] This application provides a hand mounting force detection device 100, including a first connector 10 and a second connector 20 connected to each other. The first connector 10 and the second connector 20 are arranged sequentially along a first direction, and the first connector 10 and the second connector 20 can move relative to each other in a direction parallel to the first direction. The first connector 10 is used to connect with a finger, and the second connector 20 is used to resist a force-bearing component.

[0065] The first connector 10 and the second connector 20 can be slidably connected together, and the first direction can be the direction indicated by arrow M in the figure. The first connector 10 can be fitted onto the fingers of the hand 200. For example, the first connector 10 can be fitted onto any finger; the figure illustrates this by showing the first connector 10 fitted onto the thumb.

[0066] Please refer to this as well. Figures 5 to 9 , Figure 5 yes Figure 4 The diagram shown is a structural schematic of the hand mounting force detection device 100. Figure 6 yes Figure 5 The exploded view of the hand mounting force detection device 100 shown is shown below. Figure 7 yes Figure 4This is a structural schematic diagram of the hand mounting force detection device 100 from another perspective. Figure 8 yes Figure 7 The exploded view of the hand mounting force detection device 100 shown is shown below. Figure 9 yes Figure 4 The cross-sectional view of the hand mounting force detection device 100 shown.

[0067] The hand-mounted force detection device 100 also includes a force sensor 30, which is located between the first connector 10 and the second connector 20. The force sensor 30 is used to detect the force applied to the force sensor 30 by the first connector 10 and / or the second connector 20.

[0068] The force sensor 30 can be a strain gauge pressure sensor, a piezoresistive pressure sensor, a capacitive pressure sensor, a piezoelectric pressure sensor, or an inductive pressure sensor, etc. In the illustrated embodiment, the second connector 20 abuts against the force sensor 30, and the first connector 10 abuts against the force sensor 30.

[0069] Please refer to the following for details. Figure 4 After connecting the first connector 10 to the finger, use the second connector 20 along... Figure 4 When the direction of the middle arrow is against the force-bearing component, the first connector 10 and the second connector 20 move closer together. The force sensor 30 is squeezed by the first connector 10 and / or the second connector 20, generating an electrical signal. After the signal is read by an external instrument, it can show the pressure that the force sensor 30 is subjected to by the first connector 10 and / or the second connector 20. This pressure is equal to the pressure exerted by the second connector 20 on the force-bearing component. The pressure of the second connector 20 on the force-bearing component is the installation force of the hand 200 on the force-bearing component. Thus, the force sensor 30 can measure the installation force of the hand 200 on the force-bearing component more accurately.

[0070] For example, the first connector 10 can move the pressure sensor 30 toward the direction of the second connector 20, or the second connector 20 can move the pressure sensor 30 toward the direction of the first connector 10.

[0071] It is worth noting that both the first connector 10 and the second connector 20 can abut against the force sensor 30. When the first connector 10 moves toward the second connector 20, it can apply pressure to the force sensor 30, which is equal in magnitude and opposite in direction to the force applied by the second connector 20 to the force sensor 30. Similarly, when the second connector 20 moves toward the first connector 10, it can apply pressure to the force sensor 30, which is equal in magnitude and opposite in direction to the force applied by the first connector 10 to the force sensor 30.

[0072] In this embodiment of the application, one of the first connector 10 and the second connector 20 can move toward the other of the first connector 10 and the second connector 20.

[0073] As can be seen from the above, the hand installation force detection device 100 provided in this application embodiment includes a first connector 10 and a second connector 20 connected to each other. The first connector 10 and the second connector 20 are arranged sequentially along a first direction. The first connector 10 and the second connector 20 can move relative to each other in a direction parallel to the first direction. The hand installation force detection device 100 also includes a force sensor 30 located between the first connector 10 and the second connector 20. Therefore, the first connector 10 can be connected to the finger, and the second connector 20 can be held against the force-receiving component. The force sensor 30 can accurately measure the force applied to the force sensor 30 by the first connector 10 and / or the second connector 20, thereby measuring the force applied to the second connector 20 by the force-receiving component. Thus, the installation force of the hand 200 on the force-receiving component can be accurately measured by the force sensor 30.

[0074] Please refer to Figures 5 to 9 In this embodiment, a limiting part is provided between the first connector 10 and the second connector 20, and the limiting part is used to restrict the first connector 10 and the second connector 20 from moving away from each other.

[0075] By adopting the above solution, the limiting part can restrict the first connector 10 and the second connector 20 to move away from each other, thus maintaining the connection state of the first connector 10 and the second connector 20.

[0076] The limiting part includes a suspension part 11 disposed on one of the first connector 10 and the second connector 20, and a mating part 21 disposed on the other of the first connector 10 and the second connector 20. The suspension part 11 is suspended on the mating part 21 to limit the first connector 10 and the second connector 20 from moving away from each other.

[0077] For example, the suspension part 11 can be configured as a hook, and the mating part 21 can be configured as a hanging groove or a hanging block.

[0078] By adopting the above solution, the first connector 10 and the second connector 20 can be suspended by the suspension part 11 on the mating part 21 to limit the first connector 10 and the second connector 20 from moving away from each other and to maintain the connection state of the first connector 10 and the second connector 20.

[0079] It is understandable that when both the first connector 10 and the second connector 20 are against the force sensor 30, if the suspension part 11 is not used to suspend them from the mating part 21, the first connector 10 and the second connector 20 will move away from each other.

[0080] It is also understood that when the first connector 10 and the second connector 20 approach each other, the second connector 20 can slide with part of the suspension part 11, and the side of the suspension part 11 can provide guidance for the second connector 20. After the measurement is completed, the first connector 10 and the second connector 20 move away from each other until the suspension part 11 is suspended on the mating part 21, thereby limiting the first connector 10 and the second connector 20 from moving away from each other.

[0081] For example, the first connector 10 is provided with a suspension part 11, and the second connector 20 is provided with a mating part 21.

[0082] Optionally, multiple suspension parts 11 and mating parts 21 are provided, and the suspension parts 11 and mating parts 21 are provided correspondingly, with multiple suspension parts 11 arranged at intervals around the force sensor 30.

[0083] This configuration better restricts the first connector 10 and the second connector 20 from moving away from each other, thus preventing the first connector 10 and the second connector 20 from separating.

[0084] Please refer to Figures 5 to 9 In this embodiment, the force sensor 30 includes a main body 31 and a force receiving end 32 connected together. One of the first connecting member 10 and the second connecting member 20 is connected to the main body 31, and the other of the first connecting member 10 and the second connecting member 20 abuts against the force receiving end 32.

[0085] By adopting the above scheme, the force sensor 30 can better detect the force applied to the force sensor 30 by the second connector 20.

[0086] Optionally, at least one of the first connector 10 and the second connector 20 is provided with a limiting groove, and the main body 31 is located in the limiting groove.

[0087] By adopting the above solution, the main body 31 can be limited by the limiting groove, which can prevent the main body 31 from moving at will and facilitate the installation of the main body 31.

[0088] For example, the limiting groove includes a first limiting groove 101 and a second limiting groove 201. The first limiting groove 101 is provided on the first connecting member 10, and the second limiting groove 201 is provided on the second connecting member 20. The force-bearing end 32 abuts against the bottom surface of the first limiting groove 101, and the main body 31 abuts against the bottom surface of the second limiting groove 201.

[0089] Optionally, at least one of the first connector 10 and the second connector 20 is further provided with a wiring groove, which is connected to the limiting groove and is connected to the external space of the hand mounting force detection device 100.

[0090] This configuration facilitates the routing of the force sensor 30 wires through the wiring slot to the external space of the hand-mounted force detection device 100.

[0091] For example, the wiring groove includes a first wiring groove 102 and a second wiring groove 202, the first wiring groove 102 is disposed on the first connector 10, and the second wiring groove 202 is disposed on the second connector 20.

[0092] In this embodiment, the first connector 10 is provided with a mounting groove 103, which has a slot facing away from the first direction.

[0093] By adopting the above scheme, the fingertip can be inserted into the interior of the mounting groove 103 from the groove opening facing away from the first direction, and the second connector 20 can be used to resist the force-bearing component. The force-bearing end 32 of the force sensor 30 is squeezed by the first connector 10, so that the force sensor 30 can measure the installation force of the fingertip on the force-bearing component more accurately.

[0094] For example, the first connector 10 is configured as a sleeve.

[0095] Please refer to Figures 10 to 18 , Figure 10 This is a diagram showing the usage state of the hand mounting force detection device 100 in another embodiment of this application. Figure 11 yes Figure 10 Another usage diagram of the hand mounting force detection device 100 shown. Figure 12 yes Figure 11 The corresponding top view, Figure 13 yes Figure 12 The cross-sectional view of the hand mounting force detection device 100 shown along the BB direction. Figure 14 yes Figure 13 The diagram shown is a structural schematic of the hand mounting force detection device 100. Figure 15 yes Figure 14 The exploded view of the hand mounting force detection device 100 shown is shown below. Figure 16 yes Figure 13 This is a structural schematic diagram of the hand mounting force detection device 100 from another perspective. Figure 17 yes Figure 16 The exploded view of the hand mounting force detection device 100 shown is shown below. Figure 18 yes Figure 13 The cross-sectional view of the hand mounting force detection device 100 shown.

[0096] In another embodiment, the first connector 10 includes a connecting portion 12 and a mounting portion 13 connected to each other. The force sensor 30 is located between the connecting portion 12 and the second connector 20. The mounting portion 13 is located on the side of the connecting portion 12 away from the force sensor 30. The mounting portion 13 is provided with a mounting hole 104, and the axis of the mounting hole 104 is perpendicular to the first direction.

[0097] By adopting the above scheme, a finger can be inserted into the mounting hole 104, and the second connector 20 can be used to resist the force-bearing component. The first connector 10 and the second connector 20 approach each other, and the force-bearing end 32 of the force sensor 30 is squeezed by the first connector 10, generating an electrical signal. After the signal is read by an external instrument, it can show the pressure of the first connector 10 on the force-bearing end 32. This pressure is equal to the pressure of the second connector 20 on the force-bearing component, and the pressure of the second connector 20 on the force-bearing component is the installation force of the finger on the force-bearing component. Thus, the force sensor 30 can measure the installation force of the finger on the force-bearing component more accurately.

[0098] It should be noted that the connecting part 12 and the mounting part 13 can be integrally formed, such as by injection molding or machining. Alternatively, the connecting part 12 and the mounting part 13 can be separate parts, and connected by means of bonding, welding, snap-fitting, bolting or screwing.

[0099] Optionally, the mounting hole 104 penetrates the mounting portion 13.

[0100] With this setup, different parts of the finger can be inserted into the mounting hole 104, thereby allowing for more accurate measurement of the installation force exerted by different parts of the finger on the load-bearing component.

[0101] Please refer to Figures 19 to 27 , Figure 19 This is a usage diagram of the hand mounting force detection device 100 in another embodiment of this application. Figure 20 yes Figure 19 Another usage diagram of the hand mounting force detection device 100 shown.

Figure 23 yes Figure 21 The diagram shown is a structural schematic of the hand mounting force detection device 100. Figure 24 yes Figure 23 The exploded view of the hand mounting force detection device 100 shown is shown below. Figure 25 yes Figure 21 This is a structural schematic diagram of the hand mounting force detection device 100 from another perspective. Figure 26 yes Figure 25The exploded view of the hand mounting force detection device 100 shown is shown below. Figure 27 yes Figure 21 The cross-sectional view of the hand mounting force detection device 100 shown.

[0102] In another embodiment, the connecting portion 12 protrudes from the mounting portion 13 in a second direction parallel to the axis of the mounting hole 104, and the first direction may be the direction indicated by arrow N in the figure.

[0103] By adopting the above scheme, not only can a finger be inserted into the mounting hole 104, but the second connector 20 can also be used to resist the force-bearing component. With the first connector 10 and the second connector 20 approaching each other, the force-bearing end 32 of the force sensor 30 is squeezed by the first connector 10, generating an electrical signal. This signal, when read by an external instrument, shows the pressure exerted by the first connector 10 on the force-bearing end 32. This pressure is equal to the pressure exerted by the second connector 20 on the force-bearing component, and the pressure exerted by the second connector 20 on the force-bearing component is the installation force of the finger on the force-bearing component. This allows the force sensor 30 to measure the installation force of the finger on the force-bearing component more accurately. Furthermore, the connecting part 12 can protrude from the mounting part 1. The part 3 abuts against the palm of the hand 200, causing the palm to squeeze the first connector 10, force sensor 30 and second connector 20. The second connector 20 can also be used to abut against the force-bearing component. The first connector 10 and the second connector 20 move closer to each other. The force-bearing end 32 of the force sensor 30 is squeezed by the first connector 10, generating an electrical signal. After the signal is read by an external instrument, it can show the pressure of the first connector 10 on the force-bearing end 32. This pressure is equal to the pressure of the second connector 20 on the force-bearing component. The pressure of the second connector 20 on the force-bearing component is the installation force of the palm on the force-bearing component. Thus, the force sensor 30 can measure the installation force of the palm on the force-bearing component more accurately.

[0104] Optionally, multiple force sensors 30 are provided, and the multiple force sensors 30 are spaced apart along the second direction.

[0105] With this setup, not only can the installation force at different locations be measured using different force sensors 30, but the total installation force can also be obtained by summing the values ​​measured by the different force sensors 30.

[0106] For example, two force sensors 30 can be set and used in parallel, and the force display reading is the sum of the readings of the two force sensors 30.

[0107] The hand force detection device 100 provided in the above embodiment is small in size and easy to operate. It can be worn on various parts of the fingers to detect the force results under different postures. It can closely approximate the actual operation scenario and provide real feedback on the force feeling.
