Description

Technical Field

[0001] This utility model relates to the field of noise testing technology, and in particular to a mounting bracket for an in-vehicle noise testing sensor. Background Technology

[0002] In the development of the modern automotive industry, in-vehicle noise control has become an important indicator for measuring vehicle quality and driving comfort. In order to achieve accurate monitoring and analysis of in-vehicle noise and thus optimize noise reduction design in a targeted manner, the installation and fixation of noise sensors are crucial.

[0003] Currently, a common method for testing in-vehicle noise is to directly attach the noise sensor to the driver's seat using tape. While this method is simple and flexible, the test position is inaccurate and the fixation is not secure, resulting in relatively poor accuracy and reliability of the test data. Another method is to fix the noise sensor to the seat using a mounting bracket. However, traditional mounting brackets typically use a multi-part assembly and complex bolt connection structure. The assembly and disassembly process requires multiple tightening and loosening operations using specialized tools, which is cumbersome and time-consuming. This not only increases the difficulty of later maintenance and debugging but also makes it difficult to meet the needs of rapid installation and on-site testing. At the same time, for scenarios requiring frequent relocation for testing, the large size of the bracket and the complex assembly and disassembly methods make it extremely inconvenient to carry, failing to meet the application requirements of portable noise detection and greatly reducing the efficiency and flexibility of in-vehicle noise testing.

[0004] Therefore, designing a mounting bracket for an in-vehicle noise testing sensor that can improve the assembly and disassembly efficiency of the mounting bracket while ensuring the accuracy of in-vehicle noise testing and making it easy to carry has become a technical problem that urgently needs to be solved in this field. Utility Model Content

[0005] The purpose of this invention is to at least solve the technical problem of how to design a mounting bracket for an in-vehicle noise testing sensor that, while ensuring the accuracy of in-vehicle noise testing, also improves the efficiency of mounting and dismounting the sensor and makes it easy to carry. This objective is achieved through the following technical solution:

[0006] In a first aspect, this utility model proposes a mounting bracket for an in-vehicle noise testing sensor, comprising: a bracket base for engaging with a seat in a vehicle; a bracket base having a bottom surface and a receiving groove extending along a first direction, the plane on which the bottom surface lies being a first plane, the first direction being parallel to the first plane, the bracket base being configured to be fixedly connected to the bracket base, and the relative position between the bracket base and the bracket base being adjustable along the first direction; a rotating mechanism including a first damping shaft; a bracket body, one end of which is rotatably connected to the bracket base via the first damping shaft, the first damping shaft being configured to drive the bracket body to switch between a retracted state and an extended state, wherein when the bracket body is in the retracted state, the entire bracket body is located within the receiving groove, and when the bracket body is in the extended state, at least a portion of the bracket body is located outside the receiving groove; and a mounting member for mounting the noise testing sensor body, the mounting member being connected to the bracket body, and when the bracket body is in the extended state, the mounting member is located outside the receiving groove.

[0007] This in-vehicle noise testing sensor mounting bracket can be stored in a stowed state when not in use. When in-vehicle noise testing is required, first determine the approximate test position on the seat and snap the bracket base into place. Then, connect the bracket base to the bracket base and adjust the relative position between the bracket bases in the first direction. Next, switch the bracket body from the stowed state to the unfolded state, causing the bracket body to move the mounting piece out of the receiving slot, and then install the noise testing sensor body onto the mounting piece. Since the bracket body and the bracket base are rotatably connected via a first damping shaft, the position of the noise testing sensor body inside the vehicle can be adjusted by rotating the bracket body relative to the bracket base until the position of the noise testing sensor body meets the test standards. Because the bracket body has both a stowed and unfolded state, this in-vehicle noise test sensor mounting bracket is easy to carry. Moreover, by adjusting the relative position between the bracket base and the bracket pedestal in the first direction and adjusting the specific position of the mounting component through the first damping pivot, the specific position of the final noise test sensor body can be adjusted in multiple directions, thereby ensuring the accuracy of in-vehicle noise testing. In addition, the bracket pedestal is snapped into place with the seat in the vehicle, making installation and disassembly simple and convenient, thus improving the efficiency of the in-vehicle noise test sensor mounting bracket.

[0008] In some embodiments of this utility model, the in-vehicle noise test sensor mounting bracket further includes a rangefinder, and the mounting component is installed on the rangefinder. The rangefinder is used to measure the vertical distance between the noise test sensor body and the floor of the vehicle cabin.

[0009] In some embodiments of this utility model, the support base is provided with a length scale mark, which includes a plurality of scale lines arranged at intervals along a first direction.

[0010] In some embodiments of this utility model, the extension direction of the first damping shaft is parallel to the first plane, and the rotating mechanism further includes: a positioning member connected to the support base, the positioning member having a circular hole, the axis of the circular hole being perpendicular to the first plane; and a rotating member configured to be able to connect to the circular hole and rotate around the axis of the circular hole, the first damping shaft being fixedly connected to the rotating member.

[0011] In some embodiments of this utility model, the rotating component includes: a rotating part, the outer wall of which is annular, the inner wall of which is fitted onto the outer wall of which is rotating, and the rotating part being configured to rotate about the axis of which is circular; and a fixing part connected to the rotating part, the fixing part having a fixing hole, and a first damping shaft being fixedly connected to the fixing part through the fixing hole.

[0012] In some embodiments of this utility model, the bracket body includes: a first bracket, one end of which is rotatably connected to the bracket base via a first damping shaft; and a second bracket, one end of which is rotatably connected to the end of the first bracket away from the rotating mechanism via a second damping shaft, the extension direction of the second damping shaft being the same as the extension direction of the first damping shaft, and a mounting component being connected to the end of the second bracket away from the second damping shaft.

[0013] In some embodiments of this utility model, the first support includes two spaced-apart first sub-frames, and a first receiving space for accommodating the second support is formed between the two first sub-frames.

[0014] In some embodiments of this utility model, the support base is provided with a sliding groove, and the support base has a slide rail that cooperates with the sliding groove, the slide rail extending along a first direction.

[0015] In some embodiments of this utility model, the support base includes an annular structure with an opening, the annular structure being configured to undergo elastic deformation under the action of an external force to change the opening degree.

[0016] In some embodiments of this utility model, the mounting element is a snap-fit.

Figures 1 to 3 As shown, this utility model embodiment provides a vehicle interior noise test sensor mounting bracket 10, including: a bracket base 100 for engaging with a seat in a vehicle; a bracket base 200 having a bottom surface and a receiving groove 230 extending along a first direction, the plane on which the bottom surface lies is the first plane, the first direction being parallel to the first plane, the bracket base 200 being configured to be fixedly connected to the bracket base 100, and the relative position between the bracket base 200 and the bracket base 100 along the first direction being adjustable; a rotating mechanism 300 including a first damping rotating shaft 310; and a bracket body 400, one end of which is connected to the first damping rotating shaft. The first damping shaft 310 is rotatably connected to the support base 200. The first damping shaft 310 is configured to drive the support body 400 to switch between a retracted state and an extended state. When the support body 400 is in the retracted state, the entire support body 400 is located inside the receiving groove 230. When the support body 400 is in the extended state, at least a portion of the support body 400 is located outside the receiving groove 230. The mounting member 500 is used to mount the noise test sensor body. The mounting member 500 is connected to the support body 400. When the support body 400 is in the extended state, the mounting member 500 is located outside the receiving groove 230.

[0039] In this embodiment, when the in-vehicle noise test sensor mounting bracket 10 is not in use, the bracket body 400 can be switched to a retracted state for placement. When in-vehicle noise testing is required, the approximate test position is first determined on the seat in the vehicle, and the bracket base 100 is snapped into the seat. Then, the bracket base 200 is connected to the bracket base 100, and the relative position between the bracket base 200 and the bracket base 100 is adjusted in the first direction. Next, the bracket body 400 is switched from the retracted state to the unfolded state, that is, the bracket body 400 drives the mounting piece 500 to move out of the receiving slot 230, and then the noise test sensor body is installed on the mounting piece 500. Since the bracket body 400 and the bracket base 200 are rotatably connected by the first damping pivot 310, the position of the noise test sensor body in the vehicle can be adjusted by rotating the bracket body 400 relative to the bracket base 200 until the position of the noise test sensor body meets the test standard.

[0040] As can be seen from the above analysis, since the bracket body 400 has a folded state and an unfolded state, this in-vehicle noise test sensor fixing bracket 10 has the advantage of being easy to carry. Moreover, by adjusting the relative position between the bracket base 200 and the bracket base 100 in the first direction and adjusting the specific position of the mounting part 500 through the first damping pivot 310, the specific position of the final noise test sensor body can be adjusted in multiple directions, thereby ensuring the accuracy of in-vehicle noise testing. In addition, the bracket base 100 is snapped into place with the seat in the vehicle, making installation and disassembly simple and convenient, thus improving the efficiency of the in-vehicle noise test sensor fixing bracket 10.

[0041] It is easy to understand why the first damping shaft 310 is chosen to rotatably connect one end of the bracket body 400 to the bracket base 200. This is because, in addition to having the basic function of being rotatable and adjustable, the damping shaft can also maintain the relative stability between the two rotatably connected components through damping force, making the assembly of the in-vehicle noise test sensor mounting bracket 10 more convenient and thus improving the working efficiency of the in-vehicle noise test sensor mounting bracket 10.

[0042] Specifically, when adjusting the relative position between the bracket body 400 and the bracket base 200, the operator can first utilize the rotatable adjustment characteristic of the first damping shaft 310, holding the bracket body 400 to rotate it relative to the bracket base 200 around the axis of the first damping shaft 310. Once the relative position between the bracket body 400 and the bracket base 200 is adjusted, the operator removes their hand from the bracket body 400, ensuring that no external force is applied between them. Under the damping force, the first damping shaft 310 keeps the bracket body 400 and the bracket base 200 stationary, maintaining their relative position and thus ensuring the stability of the final position of the noise test sensor body. Therefore, the first damping shaft 310 facilitates the assembly of the in-vehicle noise test sensor mounting bracket 10, thereby improving its working efficiency.

[0043] Continue to refer to Figures 1 to 3 According to an optional embodiment of the present invention, the in-vehicle noise test sensor mounting bracket 10 further includes a rangefinder 600, and the mounting component 500 is mounted on the rangefinder 600. The rangefinder 600 is used to measure the vertical distance between the noise test sensor body and the floor of the vehicle cabin.

[0044] In this embodiment, it is easy to understand that, in order to further ensure the accuracy of the final installation position of the noise test sensor body, the position of the noise test sensor body can be controlled in the second direction (which can be understood as the height direction); and it is very convenient to measure the distance between the noise test sensor body and the vehicle cabin floor in the second direction using the rangefinder 600.

[0045] Specifically, the rangefinder 600 can be a laser rangefinder. A laser rangefinder is an instrument that uses laser light to accurately measure the distance to a target. Due to the high directionality and monochromaticity of laser light, its energy is concentrated during propagation, and it is less susceptible to external interference, enabling high-precision distance measurement, typically reaching millimeter-level accuracy or even higher. This further improves the accuracy of locating the noise test sensor. Laser ranging is simple to operate and fast; the measurement result is obtained instantly after pressing the measurement button, improving work efficiency. Moreover, the internal structure of the laser rangefinder is relatively simple, without complex mechanical transmission parts, making it less affected by environmental factors, with stable performance and a long service life. It can also work reliably in harsh environments (such as high temperature, low temperature, or humidity inside a vehicle). In addition, the laser rangefinder has rich data processing capabilities, with data storage, calculation, and transmission functions. It can be connected to computers and other devices for convenient data processing and analysis, and can also achieve automated measurement and remote control, further improving the efficiency of in-vehicle noise testing.

[0046] Figure 4 for Figure 3 A structural diagram of the support body from another angle is also provided for reference. Figure 4 According to an optional embodiment of the present invention, the support base 200 is provided with a length scale mark 210, which includes a plurality of scale lines arranged at intervals along a first direction.

[0047] In this embodiment, as can be seen from the above analysis, when the in-vehicle noise test sensor mounting bracket 10 is installed, after the bracket base 100 is snapped into the seat, it is necessary to adjust the relative position between the bracket base 200 and the bracket base 100 in the first direction so as to facilitate the final positioning of the noise test sensor body.

[0048] Therefore, in this embodiment, a length scale mark 210 is provided on the bracket base 200; thus, when the relative position between the bracket base 200 and the bracket base 100 is adjusted in the first direction, the specific displacement can be determined by the length scale mark 210, thereby improving the efficiency of the position adjustment of the bracket base 200 and thus improving the overall installation efficiency of the in-vehicle noise test sensor fixing bracket 10.

[0049] It should be noted that the display scale of the length scale mark 210 should not be too large or too small. If it is too large, it will be inconvenient to install in the vehicle interior and will also be inconvenient to store and carry the entire vehicle interior noise test sensor mounting bracket 10. If it is too small, there will be insufficient relative displacement between the bracket base 200 and the bracket base 100 during adjustment. Generally, the display scale range of the length scale mark 210 should be at least greater than 20cm. Specifically, 23mm, 25mm, etc. can be selected. The specific size range of the length scale mark 210 can be determined according to the actual working conditions and is not limited.

[0050] like Figure 2 As shown, according to an optional embodiment of the present invention, the extension direction of the first damping shaft 310 is parallel to the first plane. The rotating mechanism 300 further includes: a positioning member 320 connected to the support base 200, the positioning member 320 having a circular hole 321, the axis of the circular hole 321 being perpendicular to the first plane; and a rotating member 330 configured to connect to the circular hole 321 and rotate about the axis of the circular hole 321, the first damping shaft 310 being fixedly connected to the rotating member 330. The rotating member 330 includes: a rotating part 331, the outer wall of the rotating part 331 being annular, the inner wall of the circular hole 321 being sleeved on the outer wall of the rotating part 331, the rotating part 331 being configured to rotate about the axis of the circular hole 321; and a fixing part 332 connected to the rotating part 331, the fixing part 332 having a fixing hole, the first damping shaft 310 being fixedly connected to the fixing part 332 through the fixing hole.

[0051] The first damping shaft 310 can be interference-fitted with the fixing hole, or the two can be connected by a key to ensure the stability of the connection between the first damping shaft 310 and the fixing hole. The connection method can be determined according to the actual working conditions and is not specifically limited.

[0052] Additionally, it is easy to understand that the positioning element 320 can be placed in the receiving groove 230 so that when the bracket body 400 is in the storage state, the bracket body 400 can be completely accommodated in the receiving groove 230.

[0053] In this embodiment, as described above, the bracket body 400 can switch between a retracted state and an unfolded state. To achieve this state switching, the extension direction of the first damping shaft 310 must be parallel to the first plane. Therefore, to further increase the adjustment range of the bracket body 400, the most direct solution is to allow the relative position between the first damping shaft 310 and the bracket base 100 to be changed, while maintaining the extension direction of the first damping shaft 310 always parallel to the first plane. Therefore, this embodiment provides a positioning member 320 and a rotating member 330 to adjust the relative position between the first damping shaft 310 and the bracket base 100.

[0054] Specifically, since the first damping shaft 310 is fixedly connected to the fixing part 332 of the rotating member 330, and the fixing part 332 is connected to the rotating part 331, during assembly, the rotating part 331 is inserted into the circular hole 321 of the positioning member 320 so that the inner wall of the circular hole 321 is fitted onto the outer wall of the rotating part 331, thereby enabling the rotating member 330 to rotate around the axis of the circular hole 321 as a whole, so that the first damping shaft 310 can rotate around the axis of the circular hole 321. Since the axial direction of the circular hole 321 is perpendicular to the first plane, it is easy to understand that no matter how the first damping shaft 310 rotates relative to the axis of the circular hole 321, the first damping shaft 310 will always remain parallel to the first plane.

[0055] Therefore, this configuration not only increases the adjustment range of the bracket body 400, but also does not affect the switching between the stowed and unfolded states of the bracket body 400.

[0056] refer to Figures 1 to 3According to an optional embodiment of the present invention, the bracket body 400 includes: a first bracket 410, one end of which is rotatably connected to the bracket base 200 via a first damping shaft 310; and a second bracket 420, one end of which is rotatably connected to the end of the first bracket 410 opposite to the rotating mechanism 300 via a second damping shaft 700, the extension direction of the second damping shaft 700 being the same as the extension direction of the first damping shaft 310, and the mounting member 500 being connected to the end of the second bracket 420 opposite to the second damping shaft 700.

[0057] In this embodiment, since the support body 400 includes a first support 410 and a second support 420 that are rotatably connected, the position adjustment range of the noise test sensor body can be further improved by rotating the second support 420 relative to the first support 410.

[0058] It should be noted that when the in-vehicle noise test sensor mounting bracket 10 includes a rangefinder 600, the mounting component 500 can be directly connected to the rangefinder 600. The rangefinder 600 can be rotatably connected to the end of the second bracket 420 opposite to the second damping shaft 700 via the third damping shaft 800. The extension direction of the third damping shaft 800 can be set to be the same as the extension direction of the second damping shaft 700. In other words, the position test of the noise test sensor body in the second direction can be more accurate by adjusting the relative position of the rangefinder 600 and the noise test sensor body with the second bracket 420.

[0059] The beneficial effects of the second damping shaft 700 and the third damping shaft 800 are the same as those of the first damping shaft 310. They are able to maintain the relative stability between the two rotating connecting parts through damping force while having the basic function of rotational adjustment. This makes the assembly of the in-vehicle noise test sensor mounting bracket 10 more convenient and improves the working efficiency of the in-vehicle noise test sensor mounting bracket 10. For details, please refer to the detailed analysis of the first damping shaft 310 mentioned above. It will not be repeated here.

[0060] refer to Figures 2 to 4 According to an optional embodiment of the present invention, the first support 410 includes two spaced-apart first sub-frames 411, and a first receiving space 901 for accommodating the second support 420 is formed between the two first sub-frames 411.

[0061] In this embodiment, since the first accommodating space 901 can accommodate the second bracket 420, when the bracket body 400 is in the storage state, it will occupy less space, making it more convenient to carry.

[0062] It is easy to understand that the first accommodating space 901 can also be used to accommodate the fixing part 332, that is, the rotating part 330 is also arranged between the two first sub-frames 411 to further save space.

[0063] In addition, as can be seen from the above, when the in-vehicle noise test sensor mounting bracket 10 includes a rangefinder 600, the second bracket 420 may also include two spaced second sub-frames 421, with a second accommodating space 902 formed between the two second sub-frames 421. The second accommodating space 902 is used to accommodate the rangefinder 600 (at least part of the rangefinder 600 can be located in the accommodating space), which can also save space to a certain extent.

[0064] Specifically, the following section, combining all the above solutions, details the state adjustment process of the bracket body 400 using the complete disassembly and assembly process of an in-vehicle noise test sensor mounting bracket 10 as an example:

[0065] When not in use, the bracket 10 for the in-vehicle noise testing sensor is stored in a retracted state, with both the first bracket 410 and the second bracket 420 located in the receiving groove 230, and the second bracket 420 located in the first receiving space 901 of the first bracket 410. It is easy to understand that at this time, the first damping shaft 310 extends along a third direction, which is parallel to the first plane and perpendicular to the first direction.

[0066] When conducting in-vehicle noise testing, first determine the approximate test location on the seat inside the vehicle and engage the bracket base 100 with the seat; then, connect the bracket base 200 to the bracket base 100 and adjust the relative position between the bracket base 200 and the bracket base 100 in the first direction; next, rotate the first bracket 410 around the first damping pivot 310 to move the second bracket 420, together with the first bracket 410, out of the receiving slot 230; then, rotate the second bracket 420 around the second damping pivot to move the second... The bracket 420 is removed from the receiving space of the first bracket 410. At this time, the bracket body 400 is fully extended. Then, the noise test sensor body can be installed on the mounting piece 500. The position of the noise test sensor body is adjusted by rotating the first bracket 410 around the first damping axis 310, rotating the second bracket 420 around the second damping axis 700, and rotating the rangefinder 600 around the third damping axis 800 until the position of the noise test sensor body meets the test standard. Then, the in-vehicle noise test can begin.

[0067] After the in-vehicle noise test is completed, the noise test sensor body is first removed from the mounting part 500. Then, the rangefinder 600 is rotated around the third damping pivot 800 to adjust the position of the rangefinder 600 in the second receiving space 902, so that most of the rangefinder 600 can be located in the second receiving space 902 in preparation for subsequent storage. Next, the second bracket 420 is rotated around the second damping pivot 700 so that the second bracket 420 is located in the first receiving space 901 of the first bracket 410. Finally, the first bracket 410 is rotated around the first damping pivot 310 so that the first bracket 410 drives the second bracket 420 to be stored together in the receiving slot 230. At this time, the bracket body 400 returns to the stored state.

[0068] Therefore, the in-vehicle noise test sensor mounting bracket 10 provided in this embodiment can adjust the position of the noise test sensor body by rotating the first bracket 410 around the first damping axis 310, rotating the second bracket 420 around the second damping axis 700, and rotating the rangefinder 600 around the third damping axis 800, thus ensuring the accuracy of in-vehicle noise testing.

[0069] In addition, the above adjustment process does not affect the switching between the stowed and unfolded states of the bracket body 400. The space occupied by the stowed bracket body 400 is significantly reduced compared to the unfolded bracket body 400. Therefore, this in-vehicle noise test sensor fixing bracket 10 has the advantage of being easy to carry.

[0070] like Figure 2 As shown, according to an optional embodiment of the present invention, the bracket base 100 is provided with a sliding groove 110, and the bracket base 200 has a sliding rail 220 that cooperates with the sliding groove 110, and the sliding rail 220 extends along a first direction.

[0071] In this embodiment, as can be seen from the above analysis, when it is necessary to conduct an in-vehicle noise test, it is necessary to first determine the approximate test position on the seat in the vehicle and snap the bracket base 100 into the seat; then, it is also necessary to connect the bracket base 200 to the bracket base 100 and adjust the relative position between the bracket base 200 and the bracket base 100 in the first direction. Therefore, this embodiment uses the sliding groove 110 and the sliding rail 220 to facilitate the adjustment of the relative position between the bracket base 200 and the bracket base 100 in the first direction.

[0072] Continue to refer to Figure 2 According to an optional embodiment of the present invention, the support base 100 includes an annular structure with an opening 120, the annular structure being configured to undergo elastic deformation under the action of an external force to change the opening degree of the opening 120.

[0073] In this embodiment, when it is necessary to conduct in-vehicle noise testing, after determining the approximate test position on the seat inside the vehicle, it is necessary to first snap the bracket base 100 to the seat. It is easy to understand that the most convenient way to snap the connection is to achieve this through a structure such as a clamp.

[0074] Therefore, in this embodiment, the bracket base 100 is configured as an annular structure with an opening 120. When it is necessary to snap the bracket base 100 with the seat, it is only necessary to clamp the seat through the opening 120, which improves the convenience of assembly.

[0075] In addition, this embodiment of the bracket base 100 also takes into account the assembly problem under different application scenarios, and configures the annular structure so that the opening 120 is adjustable under external force to adapt to seats of different specifications and sizes in different vehicles.

[0076] Specifically, the ring structure can be made of metal, such as alloys. Metal has high strength, which can ensure service life. Furthermore, the ring structure with an opening 120 made of metal can produce a certain elastic deformation under external force to change the opening degree of the opening 120, thereby satisfying the above-mentioned problem of adapting to seats of different specifications and sizes in different vehicle configurations.

[0077] In addition, the slide groove 110 can be provided on the outer wall of the annular structure, and the slide groove 110 can be symmetrically arranged with the opening 120.

[0078] According to an optional embodiment of the present invention, the mounting component 500 is a snap-fit.

[0079] In this embodiment, it is easy to understand that the buckle has advantages such as stable connection and convenient assembly and disassembly; therefore, when the buckle is used to install the noise test sensor body, it can improve the installation efficiency while ensuring the stability of the noise test sensor body, and disassembly is also very convenient.

[0080] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
