The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0017] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the implementation of the utility model will be clearly and completely described below in conjunction with the drawings in the implementation of the utility model. Obviously, the described implementation is only a part of the implementation of the utility model, not all of the implementations. Based on the implementation of the utility model, other implementations obtained by those skilled in the art without making creative work are within the scope of protection of the utility model.

[0018] like Figure 1 and Figure 2As shown, the embodiment of the utility model proposes a measuring instrument 100, which includes a housing 10, a weighing component 20, a distance measuring component 30 and a processing component 40. The weighing component 20, the distance measuring component 30 and the processing component 40 are all installed on the housing 10, and the weighing component 20 is used to measure the weight information of an object. The distance measuring component 30 includes a tape measure 31 and a code reader 32. The tape measure 31 is provided with a code 311, and the code 311 is used to identify the distance between the position of the code 311 and the front end A of the tape measure 31. The code reader 32 is used to read the code 311 on the tape measure 31 and generate the size information of the object. The processing component 40 includes a processor 41 and a display screen 42. The processor 41 is electrically connected to the weighing component 20, the code reader 32 and the display screen 42. The processor 41 is used to receive the weight information transmitted by the weighing component 20 and process the weight information into a weight value displayed on the display screen 42. The processor 41 is further configured to receive the dimension information transmitted by the code reader 32 and process the dimension information into one of a length value, an area value and a volume value displayed on the display screen 42 according to the working mode.

[0019] Among them, the working mode includes a length measurement working mode, an area measurement working mode and a volume measurement working mode. It should be noted that in the length measurement working mode, the encoder 311 only needs to read the size information once. In the area measurement working mode, the encoder 311 needs to read the size information twice, that is, read the length and width information of the object, and the processor 41 calculates the area value according to the received length and width information. In the volume measurement working mode, the encoder 311 needs to read the size information three times, that is, read the length, width and height information of the object, and the processor 41 calculates the volume value according to the received length, width and height information.

[0020] Among them, the processor 41 can be a central processing unit (CPU), and the processor 41 can also be other general-purpose processors 41, digital signal processors 41 (DSP), application-specific integrated circuits (ASIC), field-programmable gate arrays (FPGA) or other programmable logic devices, discrete gate or transistor logic devices, discrete hardware components, etc.

[0021] The code 311 may be, but is not limited to, a black and white step code.

[0022] The measuring instrument 100 proposed in the embodiment of the utility model can not only measure the weight of an object through the weighing component 20, but also measure the length, area or volume of an object through the distance measuring component 30, that is, the measuring instrument 100 integrates several functions of weight measurement, length measurement, area measurement and volume measurement, and is simple to operate and convenient to carry. In addition, in the working mode of length measurement, area measurement and volume measurement, the processor 41 receives the dimension information transmitted by the code reader 32 and directly processes the dimension information into a length value, an area value or a volume value, without the operator having to perform manual conversion, which not only improves the convenience of use, but also reduces errors.

[0023] In some embodiments, the measuring tape 31 is provided with scales.

[0024] In some embodiments, the weighing component 20 has a measuring range of 0 to 10 kg.

[0025] like Figure 3 As shown, in some embodiments, the code reader 32 includes a structural member 321 and a photoelectric sensor 322 . The structural member 321 is provided with a slit 3211 , and the measuring tape 31 passes through the slit 3211 . The photoelectric sensor 322 is installed on the structural member 321 , and the photoelectric sensor 322 is used to read the code 311 on the measuring tape 31 .

[0026] like Figure 1 and Figure 4 As shown, in some embodiments, the weighing assembly 20 includes a suspension assembly 21, and the suspension assembly 21 is used to suspend the measured object. The housing 10 includes a top wall 11 and a bottom wall 12, and the top wall 11 and the bottom wall 12 are arranged opposite to each other in the first direction X. The top wall 11 is provided with an opening 111, and the front end A of the tape measure 31 extends from the opening 111. The suspension assembly 21 is arranged on the bottom wall 12 of the housing 10. The first direction X is the length direction of the housing 10, or when the user views the display screen 42 in a normal posture, the first direction X is the up and down direction of the housing 10.

[0027] Taking a right-handed person as an example, in a common usage scenario, when a user uses a handheld electronic scale, he holds the electronic scale with his right hand, then hangs the object on the suspension component 21 at the bottom of the electronic scale, and then lifts his right hand to make the object leave the ground, and the weight value of the object can be measured. When a user uses a tape measure 31, he holds the tape measure 31 with his right hand, and pulls out the tape of the tape measure 31 from the right hand's base with his left hand for measurement. In this embodiment, by setting the tape measure 31 to extend from the opening 111 of the top wall 11, and the suspension component 21 of the weighing component 20 is set on the bottom wall 12 of the housing 10, this embodiment satisfies the above two usage habits. In the process of switching from using the weighing component 20 for weight measurement to using the tape measure 31 for length measurement, or switching from using the tape measure 31 for length measurement to using the weighing component 20 for weight measurement, the user can maintain a grip to hold the measuring instrument without changing the grip, thereby improving the convenience of using the measuring instrument.

[0028] like Figure 1 and Figure 4 As shown, in some embodiments, the measuring instrument 100 further includes a first button 50 electrically connected to the processor 41, and the first button 50 is used to generate trigger information when pressed by a user, and the processor 41 is used to record the size information read by the code reader 32 when receiving the trigger information. For example, in the working mode of volume measurement, it is necessary to measure the three values ​​of length, width and height of the object. When the user pulls the measuring tape 31 into place along the length direction of the object, press the first button 50, and the processor 41 records the size information read by the code reader 32 and processes it into the length value of the object. When the user pulls the measuring tape 31 into place along the width direction of the object, press the first button 50, and the processor 41 records the size information read by the code reader 32 and processes it into the width value of the object. When the user pulls the measuring tape 31 into place along the height direction of the object, press the first button 50, and the processor 41 records the size information read by the code reader 32 and processes it into the height value of the object. Then, the processor 41 multiplies the length value, the width value and the height value to obtain the volume value of the object.

[0029] like Figure 1 and Figure 4As shown, in some embodiments, the housing 10 includes a top wall 11, a bottom wall 12, a first side wall 13, and a second side wall 14. The top wall 11 and the bottom wall 12 are arranged opposite to each other in a first direction X, and the first side wall 13 and the second side wall 14 are arranged opposite to each other in a second direction Y. The second direction Y is perpendicular to the first direction X, and the second direction Y is the width direction of the housing 10, or when the user watches the display screen 42 in a normal posture, the second direction Y is the left and right direction of the housing 10. The top wall 11 is provided with an opening 111, and the front end A of the tape measure 31 extends from the opening 111. The opening 111 is arranged near the first side wall 13, and the first button 50 is arranged on the second side wall 14, and the first button 50 is arranged near the top wall 11. In this embodiment, the opening 111 is set on the top wall 11 of the shell 10 and close to the first side wall 13, and the first button 50 is set on the second side wall 14 and close to the top wall 11. In this way, when the user uses the measuring instrument to measure the length, the user holds the shell 10 of the measuring instrument with his hand, and the position where the thumb is naturally placed is the position of the first button 50. The user can press the first button 50 with the thumb. The position design of each component in this design method is ergonomic, which improves the comfort of user use.

[0030] like Figure 1 and Figure 5 As shown, in some embodiments, the measuring instrument 100 further includes a locking assembly 60 and a second button 70. The locking assembly 60 is mounted on the housing 10. The locking assembly 60 is used to automatically lock the measuring tape 31 after the measuring tape 31 is pulled out of the housing 10 to prevent the measuring tape 31 from retracting into the housing 10. The second button 70 is connected to the locking assembly 60. The second button 70 is used to unlock the locking assembly 60 when pressed by a user, so that the measuring tape 31 automatically retracts into the housing 10. The existing measuring tape 31 is mostly designed so that the measuring tape 31 automatically retracts into the housing 10 in the absence of external force. In the case of improper use by the user, the sudden retraction of the measuring tape 31 may cause cuts to the user. In this embodiment, by setting the locking assembly 60 to automatically lock the measuring tape 31 after the measuring tape 31 is pulled out of the housing 10, the risk of the measuring tape 31 causing cuts to the user due to the sudden retraction of the measuring tape 31 is avoided, thereby improving the safety of the measuring instrument.

[0031] like Figure 6As shown, in one embodiment, the locking assembly 60 includes a connecting rod 61 and an elastic member 62. The middle portion of the connecting rod 61 is rotatably connected to the housing 10 to form a lever. The connecting rod 61 includes a first end and a second end. The first end of the connecting rod 61 abuts against the tape measure 31. The elastic member 62 is installed on the housing 10 and abuts against the first end of the connecting rod 61. The elastic member 62 is used to provide elastic force so that the first end of the connecting rod 61 presses the tape measure 31. The second button 70 is arranged opposite to the second end of the connecting rod 61. When the user presses the second button 70, the second button 70 pushes the second end of the connecting rod 61. The first end of the connecting rod 61 is tilted due to the lever action, and the tape measure 31 automatically retracts into the housing 10 without the friction of the first end of the lever. Specifically, the user pulls out the measuring tape 31 along the direction E1, the elastic member 62 abuts against the first end of the connecting rod 61 along the direction E2, the first end of the connecting rod 61 presses the measuring tape 31, and the measuring tape 31 cannot automatically retract into the housing 10. When the measuring tape 31 needs to be retracted into the housing 10, the user presses the second button 70 along the direction E3, the connecting rod 61 swings along the direction E4, and the first end of the connecting rod 61 leaves the measuring tape 31, so that the measuring tape 31 can automatically retract into the housing 10. The elastic member 62 can be, but is not limited to, a spring or a spring.

[0032] like Figure 1 and Figure 4 As shown, in some embodiments, the second button 70 is disposed on the first side wall 13, and the second button 70 is disposed close to the top wall 11. In this embodiment, by disposing the second button 70 on the first side wall 13, and disposing the second button 70 close to the top wall 11, when the user uses the measuring instrument to measure the length, the position where the index finger is naturally placed when holding the housing 10 of the measuring instrument is the position of the second button 70, and the user can press the second button 70 with the index finger. The position design of each component in this design method is ergonomic, which improves the comfort of the user.

[0033] like Figure 4 and Figure 5 As shown, in some embodiments, a portion of the first side wall 13 is recessed toward the second side wall 14 to form a first recessed portion 131, and a portion of the second side wall 14 is recessed toward the first side wall 13 to form a second recessed portion 142. The first recessed portion 131 and the second recessed portion 142 form a holding position for a user to hold the measuring instrument 100.

[0034] Specifically, when the user holds the measuring instrument 100, the thumb of one hand of the user is located in the second recessed portion 142, and the other four fingers are located in the first recessed portion 131, so that the measuring instrument is not easy to fall off from the user's hand. In particular, when the user uses the measuring instrument to measure the weight of an object, the top of the first recessed portion 131 and the top of the second recessed portion 142 can form a good mechanical support to prevent the measuring instrument from falling off from the user's hand.

[0035] Of course, the shell 10 is not provided with the first recessed portion 131 and the second recessed portion 142. For example, in some other embodiments, the first side wall 13 is provided with a first rough structure for increasing friction, and the second side wall 14 is provided with a second rough structure for increasing friction. By providing the first rough structure and the second rough structure, the user can hold the measuring instrument 100 more firmly.

[0036] like Figure 1 and Figure 4 As shown, in some embodiments, the first button 50 is provided with a first protrusion 51. By providing the first protrusion 51, the friction between the first button 50 and the user's finger can be increased, so that the user's finger will not shift when pressing the first button 50, thereby improving the user's experience. In some embodiments, the first protrusion 51 is a convex ridge protruding from the surface of the first button 50. Of course, the first protrusion 51 is not limited to being set as a convex ridge. For example, in some other embodiments, the first protrusion 51 is also a convex point protruding from the surface of the first button 50. Of course, in some other embodiments, the first button 50 is not provided with the first protrusion 51. It can be determined according to actual design requirements.

[0037] like Figure 1 and Figure 5 As shown, in some embodiments, the second button 70 is provided with a second protrusion 71. By providing the second protrusion 71, the friction between the second button 70 and the user's finger can be increased, so that the user's finger will not be displaced when pressing the second button 70, thereby improving the user's experience. In some embodiments, the second protrusion 71 is a convex ridge protruding from the surface of the second button 70. Of course, the second protrusion 71 is not limited to being set as a convex ridge. For example, in some other embodiments, the second protrusion 71 is also possible to be a convex point protruding from the surface of the first button 50. Of course, in some other embodiments, the second button 70 is not provided with the second protrusion 71. It can be determined according to actual design requirements.

[0038] like Figure 1As shown, in some embodiments, the weighing assembly 20 includes a suspension assembly 21 and a load sensor 22. The suspension assembly 21 is arranged outside the housing 10 and is used to suspend the measured object. The load sensor 22 is arranged inside the housing 10 and connected to the suspension assembly 21. The load sensor 22 is electrically connected to the processor 41. The load sensor 22 is used to measure the weight information of the object suspended on the suspension assembly 21 and transmit the weight information to the processor 41. Specifically, in the actual measurement process, when an object is suspended on the suspension assembly 21, the object forms a pulling force on the suspension assembly 21, and the components of the load sensor 22 are deformed or displaced under the action of the pulling force of the suspension assembly 21. The load sensor 22 generates a corresponding measurement signal through the deformation or displacement of the components, and transmits the measurement signal to the processor 41. The suspension assembly 21 can be, but is not limited to, a hook.

[0039] like Figure 1 As shown, in some embodiments, the measuring instrument 100 also includes a third button 80, which is electrically connected to the processor 41. The third button 80 is used to switch the working mode of the measuring instrument 100 when pressed by a user. The working mode includes at least one of distance measurement, area measurement, volume measurement and weight measurement.

[0040] like Figure 1 and Figure 5 As shown, in one embodiment, the shell 10 also includes a panel 15 and a back panel 16, the panel 15 and the back panel 16 are arranged relative to each other in a third direction Z, the third direction Z is perpendicular to the first direction X and the second direction Y, the third direction Z is the thickness direction of the shell 10, the panel 15 is connected to the top wall 11, the bottom wall 12, the first side wall 13 and the second side wall 14, the back panel 16 is connected to the top wall 11, the bottom wall 12, the first side wall 13 and the second side wall 14, and the display screen 42 and the third button 80 are both arranged on the panel 15 of the shell 10.

[0041] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of various equivalent modifications or replacements within the technical scope disclosed by the utility model, and these modifications or replacements should be included in the protection scope of the utility model.
